CROSS REFERNCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of priority to an Iran patent application having serial number 139450140003000073 filed on Mar. 28, 2015, which subsequently issued as Iran patent number 86446 on Aug. 12, 2015, the entire content of which is incorporated herein by reference. 
       TECHNICAL FIELD 
       [0002]    The present application relates generally to drip irrigation systems, more particularly, to an electro-anti deposit device for removing mineral deposits that block irrigation drippers, by using electricity. 
       BACKGROUND 
       [0003]    Drip irrigation systems, save water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes (e.g., drippers) that deliver water directly to the base of the plant. In such drip irrigation systems, pressure produced by a pump or due to difference of elevation can cause water to flow in the network of pipes and drip onto the designated areas via drippers placed on the pipes. In order to prevent substances such as sand and soil from entering the water, and clog the drippers, the water may be filtered prior to entering the irrigation system. In addition, fertilizers and plant food and nutrients may be added to the water. 
         [0004]    However, issues may arise while using drip irrigation systems. In various geographical areas, for example in areas having hard water resources, salt, minerals or other particles contained in water may settle in the pipes and in the drippers over time and block the dripper openings. The mineral deposit can disable the irrigation system and prevent the irrigation process, for example, by causing uneven irrigation. Removal of the mineral deposits from the irrigation systems can be a costly process, which includes replacing the blocked drippers or pipes or cleaning the drippers and pipes, which may require disassembling and reassembling whole or parts of the system. 
         [0005]    In some instances, refining or filtering water prior to feeding the water into the irrigation system may reduce the particles contained in the water. In other cases, washing and cleaning the drippers may solve the problem by removing the mineral deposit. In yet other instances, control of water pressure has been suggested such that the pressure causes the mineral deposit to be removed from drippers. However, the solutions previously suggested require the drip irrigation network to be restructured and redesigned. As a result, the cost of maintenance can be high and unaffordable for farmers. 
         [0006]    Therefore, a need exists for an economically beneficial solution for removing mineral deposit from drip irrigation drippers without a need for restructuring the irrigation network. 
       SUMMARY 
       [0007]    An electro-anti deposit device coupled to an irrigation pipe for removing mineral deposit from a set of irrigation drippers of the irrigation pipe is provided. The electro-anti deposit device includes an engine configured to move the electro-anti deposit device along the irrigation pipe; and a mineral deposit removal module. The mineral deposit removal module includes a water container for creating an ionic environment at an irrigation dripper from among the set of irrigation drippers, wherein the irrigation dripper is covered with the mineral deposit; a first battery for generation electric current; and two electrodes connected to two poles of the first battery, wherein a space separates tips of the two electrodes. The electro-anti deposit device can be moving configured to moisten the mineral deposit at the irrigation dripper using the water from the water container, enable contact between the two electrodes through the moistened mineral deposit, and generate an electric current using the first battery and pass the generated electric current through the mineral deposit from one of the two electrodes to other of the two electrodes, such that the electric current dissolves the mineral deposit. 
         [0008]    The electro-anti deposit device includes a remote control module configured to control the engine for moving the electro-anti deposit device along the irrigation pipe. The engine can be operated by a second battery. The first battery or the second battery can be a rechargeable battery. 
         [0009]    The electro-anti deposit device includes a set of rollers, wherein the movement of the electro-anti deposit device includes sliding on the irrigation pipe using the set of rollers. At least one of the set of rollers can be coupled to a belt and the belt can be coupled to a shaft rotated by the engine, and the rotation of the shaft rotates the belt, which in turn rotates the at least one roller, and the rotation of the at least one roller causes the electro-anti deposit device to move along the irrigation pipe. 
         [0010]    The electro-anti deposit device includes two vertical plates, wherein each vertical plate is placed on one side of the irrigation pipe such that together the vertical plates squeeze the irrigation pipe and hold the electro-anti deposit device tight thereto. 
         [0011]    The electro-anti deposit device includes a horizontal plate coupled to one of the two vertical plates, wherein the horizontal plate is configured to mount the engine via a fastening element. The fastening element includes nuts and bolts. The engine can be configured to move the electro-anti deposit device until the water container is aligned with the irrigation dripper. 
         [0012]    The electro-anti deposit device includes a controller configured to stop the movement of the electro-anti deposit device once the water container is aligned with the irrigation dripper. The controller can be configured to automatically stop the movement of the electro-anti deposit device once the water container is aligned with the irrigation dripper. The controller can be configured to stop the movement of the electro-anti deposit device once the water container is aligned with the irrigation dripper based on a manual input from a user.

     DETAILED DESCRIPTION 
       [0018]    In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings. 
         [0019]    In drip irrigation systems, water enters irrigation pipes with a pressure provided by one or more pumps or due to a difference in elevation. The water entering the irrigation pipes drops on crops, shrubs or under trees from emitters or drippers installed on the pipe. In some cases, in order to prevent particles from entering the irrigation pipe and blocking the drippers, water may be filtered prior to entering the irrigation pipe. Fertilizers and plant food can be added to the water. Prior to irrigation, various tests may be performed to determine the amount of water needed at a location and by the plantation at that location. Based on the test results, number of drippers are adjusted such that each tree, bush or shrub receives adequate amount of water. 
         [0020]    The drip irrigation method can be used in various locations. In large farms, the area of the farm may be divided into smaller pieces and each piece provided with an irrigation system. However, issues may arise while using drip irrigation. In some cases, the minerals and particles in water, especially in areas with heavy water, may cause creation of mineral deposits inside the drippers that may cause blockage of the drippers. Blockage of drippers overtime may damage the irrigation system and prevent plantations from receiving enough water supply. 
         [0021]    Various solutions may be considered to solve the dripper blockage issue. Some of the solutions may include water filtration, washing the irrigation pipes drippers, using chemicals to dissolve and clean mineral deposits. Each of these solutions have disadvantages such as high costs and limited availability. In some cases, due to unavailability of the solutions, farmers may stop using drip irrigation systems altogether. 
         [0022]    Some other suggested solutions include increasing water pressure, designing special types of anti-clogging drippers, etc. However, the suggested solutions would require special preparations of the land, or replacing part of or the whole irrigation system with improved suggested components, which may incur extra costs and as a result not practical for farmers. 
         [0023]    The disclosed electro-anti deposit device can be installed on existing drip irrigation systems without a need for changes in the irrigation system. The electro-anti deposit device is a low cost device that can facilitate removal of mineral deposits from drippers of a drip irrigation system. 
         [0024]      FIG. 1  illustrates an electro-anti deposit device, according to an implementation. The electro-anti deposit device, as disclosed, facilitates removal of mineral deposit on drippers of a drip irrigation system using an electric current. An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma. 
         [0025]    For a steady flow of charge through a surface, the current I (in amperes) can be calculated with the equation (1):

         [0026]    In equation (1), the electric current I can vary by time. More generally, electric current can be represented as the rate at which charge flows through a given surface as:

         [0027]    As shown in  FIG. 1 , an electro-anti deposit device  105  includes an engine  109  that operates with a battery  111 . The engine  109  produces power for the electro-anti deposit device  105  to slide on an irrigation pipe  101 . Arrow  107  illustrates the direction of sliding of electro-anti deposit device  105  on pipe  101 . To this end, the electro-anti deposit device  105  may also include a set of rollers  113 . The rollers  113  can have a spool shape to fit the shape of the irrigation pipe  101 . 
         [0028]      FIG. 2  illustrates a cross section of a roller  113  of an electro-anti deposit  105  device (not shown) attached to an irrigation pipe  101 . The rollers  113  enable the electro-anti deposit device  105  to slide on irrigation pipe  101 . The electro-anti deposit device  105  may also include one or more plates  115  made from non-corrosive material such as, for example, polyethylene, to protect the electro-anti deposit device  105  against corrosion. 
         [0029]    The electro-anti deposit device  105  may also include a mineral deposit removal module. The mineral deposit removal module may include a water container  117  two electrodes  123  and  125  and a battery  119 . The water container  117  may be in the form of a sponge, a spraying device, etc. The irrigation pipe  101  includes multiple emitters or drippers  103   a - 103   n  via which the water flowing inside the irrigation pipe  101  drops on the earth below the pipe  101 . 
         [0030]    The power generated by battery  119  runs through electrodes  123  and  125  via wires  121 . The electrodes  123  and  125  can be installed on a base such that a distance of a few millimeters separates the tips of the electrodes (e.g., a cathode and an anode). When the electro-anti deposit device  105  slides forward on the irrigation pipe  101  in the direction of arrow  107 , the water container (e.g. sponge  117 ) comes to contact with the tip of each dripper  103   a - 103   n . The water from the container  117  dampens the tip of the dripper  103   a - 103   n  and creates an ionic environment. The moisture from water can also loosen the mineral deposit at the dripper tip. After the dripper tip  103   a - 103   n  being moistened by the water from the container  117 , while the electro-anti deposit device  105  is still sliding in direction  107 , the electrodes  123  and  125  come in contact with the dripper tip  103   a - 103   n . Coming to contact with the moist mineral deposit at the tip of the dripper, the circuit between battery  119  and electrodes  123  and  125  can be established and the electric current produced by battery  119  flows through wires  121  and electrodes  123  and  125 . The electric current passing through the mineral deposit  201  raises the temperature of the mineral deposit and dissolves the mineral deposit. The wires  121  can be from stainless type wires which are resistant against corrosion due to water and minerals contained in water. The batteries  119  and  111  can be selected from various battery types such as primary cell batteries, rechargeable batteries, solar batteries, etc. 
         [0031]      FIG. 3  illustrates a close-up view of the electrical circuit facilitating removal of the mineral deposit on a dripper. As shown in  FIG. 3 , the electric current produced by battery  119  flows through wires  121  into electrodes  123  and  125 . The water container  117  and the electrodes  123  and  125  are positioned on the electro-anti deposit device  105  such that the water container comes in contact with the mineral deposit  201  and moistens the mineral deposit  201  prior to the electrodes  123  and  125  come to contact with the mineral deposit  201 . 
         [0032]    The moist mineral deposit  201  at the tip of dripper  103  can conduct the electric current from electrode  125  to electrode  123 . In some cases, the electric current can generate a spark between electrodes  123  and  125  such that the current passes through the mineral deposit  201 . The electric current passing through mineral deposit  201  can raise the temperature of the mineral deposit and facilitate decomposing of the mineral deposits. The raised temperature can also dissolve the mineral deposit. The decomposed mineral deposits can then be loosen due to temperature and exit the dripper by water dripping from the drippers. 
         [0033]      FIGS. 4A-4B  illustrate different views of an electro-anti deposit device, according to an implementation of the instant application. As shown in  FIGS. 4A and 4B , in one implementation, the electron-anti deposit device  105  includes two vertical plates  115 . Each vertical plate  115  may be placed on one side of the irrigation pipe  101  (not shown) such that together they squeeze the irrigation pipe  101  and hold the device  105  tight thereto. 
         [0034]    The rollers  113  may also be placed between the two vertical plates  115  on the top of the irrigation pipe  101 . Each roller  113  may be coupled on a first side thereof to the first vertical plate  115  and on a second side thereof to the second vertical plate  115 . The fastening element used may include a bolt and a screw  401 , for example. The bolt may pass through an aperture within the first vertical plate  115 , an aperture within a center of the roller  113  and then an aperture within the second vertical plate  115  and may then engage with a screw to maintain its position. 
         [0035]    The electro-anti deposit device  105  may also include a horizontal plate  403 . The horizontal plate  403  may be coupled to one of the vertical plates  115 . The horizontal plate may be used for mounting the engine  109 . The engine  109  may be mounted to the horizontal plate by a fastening element. The fastening element may include nuts and bolts, in one example. 
         [0036]    Referring back to  FIG. 1 , the electro-anti deposit device  105  may also include a remote control  129  for remotely controlling the engine  109 . A person working with the electro-anti deposit device  105  can use the remote controller  129  to turn ON/OFF and Start/Stop the engine  109  to slide in direction  107  or in a direction opposite  107  and adjust the position of the electro-anti deposit device  105  on the irrigation pipe  101 . When ON and in the start mode, the engine  109  rotates a shaft  133 , which is coupled to a belt  131 . The belt  131  is in turn coupled to the one of the rollers  113  as shown. The rotation of the shaft  133  rotates the belt  131 , which in turn rotates the roller  113 . As a result, the electro-anti deposit device  105  moves on the pipe  101 . 
         [0037]    The engine  109  can be configured to move the electro-anti deposit device  105  until the water container  117  is aligned with an irrigation dripper  103   a - 103   n.    
         [0038]    The electro-anti deposit device  105  may include a controller  129  configured to stop the movement of the electro-anti deposit device  105  once the water container  117  is aligned with the irrigation dripper  103   a - 103   n . The controller  129  can be configured to automatically stop the movement of the electro-anti deposit device  105  once the water container  117  is aligned with the irrigation dripper  103   a - 103   n . The controller  129  can be configured to stop the movement of the electro-anti deposit device  105  once the water container  117  is aligned with the irrigation dripper  103   a - 103   n  based on a manual input from a user. 
         [0039]    For example, the remote control  129  can be used by a user to stop the electro-anti deposit device  105  at each dripper  103   a - 103   n  such that the electric current from batteries  119  pass through the electrodes  123  and  125  and the mineral deposit  201 . In some instances, a timer may be attached to the engine  109  such that the movement and stopping intervals of the electro-anti deposit device  105  is automatically controlled via the timer. For example, a 2 seconds stop time at each dripper  103   a - 103   n  may provide enough time for the electric current from battery  119  to pass through the mineral deposit  201 . 
         [0040]    The electro-anti deposit device  105  may also include one or more ball bearings  127  or other similar components to provide a balance of the electro anti-deposit device  105  on the irrigation pipe  101 .
