TECHNICAL FIELD 
       [0001]    The present invention relates to a device provided in a farmland, orchard, fish farm and the like to repel wild animals and pest birds, and particularly, to a device for effectively scaring away wild animals and pest birds using laser beams, regardless of place or time. 
       BACKGROUND ART 
       [0002]    As use of scarecrows does not work well for the purpose of scaring away wild animals or birds, more and more farm holders are adopting electric fences. Although considered one of the most effective ways to keep wild animals away, electric fencing is challenged by a few shortcomings, such as failure to respond to birds and high costs for installation and maintenance. 
         [0003]    Birds&#39; excreta, not only insanitary but even corrosive as well, may do severe damage to, e.g., food storage facilities. 
         [0004]    Boar, water deer, or other pest wild animals are recently in sharp overpopulation, harming farmlands or graveyards. Boar are nocturnal animals that only come out at night to forage for food. Water deer are active both day and night. Such pest animals are impossible to repel only with alert sirens or lighting devices. 
         [0005]    Introduced were several approaches for repelling or deterring wild animals. Korean Utility Model Registration No. 20-0408878 discloses a wild animal repelling device that keeps away animals with light radiations, but not with sounds. This device, however, is helpless with day-active animals, Further, the device is limited in effect by its design to reflect light only in some directions, not all. This type of devices adopt only light beaming for animal repelling, and to achieve an effect, many units of such device should be deployed in a target area. 
         [0006]    Another conventional way is the use of alert sounds for repelling birds, an example of which is disclosed in Korean Utility Model Registration No. 20-0239741. The device set forth therein is limited in effect by repelling birds only by way of distressing sounds. 
         [0007]    Some other types of wild animal repelling devices are equipped with a laser, which are used in airports or farms. For these devices to work properly, laser beams need to be aimed at the target pests.

       SUMMARY 
     Objects 
       [0011]    The conventional devices for repelling, pest birds and wild animals, as described above, are provided for a single purpose only, and thus are limited in use. The conventional wild animal repelling devices using laser should be configured with a laser beaming device that itself emits a laser beam, and it thus works well for pest repelling. However, the laser repelling devices overburden farm holders with installation/maintenance costs. 
         [0012]    The present invention has been made to address the above issues, and an object of the present invention is to provide a device for repelling wild animals and pest birds using laser that is configured to have a rotational body, rotated by drive of a motor, installed on a support at a predetermined height and modules for producing laser installed in the rotational body, so as to emit laser in all directions as the motor drives, wherein the device may be installed and used regardless of time or place, e.g. in a farmland, orchard, fish farm, grain silo, highway, or airport, effectively repelling or deterring pest birds or other wild animals. 
         [0013]    Another object of the present invention is to enable the height and angle at which laser is emitted to be adjusted, so as to vary the range of laser beaming depending on the type of wild animals or pest birds for diversified applications. 
       Configuration 
       [0014]    To achieve the above objects, according to the present invention, a device for repelling wild animals and pest birds using laser comprises a support; a cylindrical fixing body connected with the support, the fixing body having a bottom surface opened to allow a driving motor to be installed therein; and a cylindrical rotational body having an upper portion partially inserted into an inside of the fixing body, the rotational body having a top surface closed to allow the rotational body to be rotated by a driving shaft connected with the driving motor and a bottom surface opened, wherein a rotatable slip ring is inserted and installed in the rotational body to supply power to a rotating part of the rotational body, and wherein a laser module is inserted and installed in an outer side of the rotational body to emit laser. 
       Effects 
       [0015]    Accordingly, according to the present invention, the device for repelling wild animals and pest birds using laser may be installed and used regardless of time or place, e.g., a farmland, orchard, fish farm, grain silo, highway, or airport. 
         [0016]    The device adopts the laser modules that are inexpensive and produces laser beams traveling long distances, and thus, offers an effective means for deterring wild animals or pest birds. 
         [0017]    The height or angle at which laser beams are radiated may be easily adjusted depending on the direction in which pest birds or wild animals approach, allowing for effective repelling of the animals.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0023]    Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings to be easily made by one of ordinary skill in the art to which the present invention pertains. 
         [0024]    According to the present invention, a device  100  for repelling wild animals and pest birds using laser, as shown in  FIGS. 1 to 3 , includes a support  110  firmly secured to as ground or a bottom of a building; a cylindrical fixing body  130  fixed to an upper end portion of the support  110 , having a top surface closed to allow the cylindrical fixing body  130  to be connected with the support  110  at a middle portion thereof and a bottom surface opened to allow a driving motor  120  to be inserted and installed therein; a decelerator  140  connected with a driving shaft  121  of the driving motor  120  to reduce a rotation count; and a cylindrical rotational body  160  having an upper portion partially inserted into the inside of the fixing body  130 , the cylindrical rotational body  160  having a top surface closed to have a small diameter part  161  and a bottom surface opened to have a brush-type slip ring  150  inserted and installed therein, wherein the small diameter part  161  is connected with the driving shaft  121  of the driving motor  120  and a driving shaft (not shown) of the decelerator  140 , and the slip ring  150  allow for supply of DC power. 
         [0025]    The rotational body  160  has laser module installation holes  162  in an outer side thereof, and laser modules  170  are inserted in the laser module installation holes  162  to receive power from the slip ring  150  and to emit laser. 
         [0026]    The slip ring  150  includes a slip part  151  that is inserted into the rotational body  160  from under the rotational body  160  and that may rotate to supply power to the laser modules  170 , a fixing bracket part  152  fixed to the bottom surface of the rotational body  160 , and a fixing part  153  supplying power to the driving motor  120 . 
         [0027]    The support  110  may be shaped as a “U” lying at 90 degrees to firmly secure itself to, e.g., a supporting table of a ground or orchard. 
         [0028]    Accordingly, DC power may be supplied through the slip ring  150  to the laser modules  170  to allow the laser modules  170  to emit laser, simultaneously supplied to the driving motor  120 . 
         [0029]    Here, the driving motor  120  may be an AC driving motor or a DC driving motor. The power supplied to the laser modules  170  may be configured separately from the power supplied to the driving motor  120 . 
         [0030]    The above-described slip ring  150  may be configured by one of ordinary skill in the art from known techniques, and no further detailed description thereof is given. 
         [0031]    The laser modules  170  in the rotational body  160  may be configured to have heights or angles adjusted relative to the ground. 
         [0032]    In other words, the rotational body  160  has trenches  163  formed in an outer surface thereof in a longitudinal direction thereof. Sliding parts  164  where the laser modules  170  are installed are inserted into the trenches  163 , respectively, to slide up and down. Each trench  163  has multiple grooves  163   a  formed at predetermined intervals on both side surfaces thereof. Each sliding part  164  has protrusions  164   a  that, when the sliding part  164  slides up and down, are engaged with the grooves  163   a  to hold the sliding part  164  at a height. 
         [0033]    The sliding parts  164  are connected with a rotational shaft (not shown) provided at the center of the rotational body  160  and may be slid up and down along the grooves  163  with respect to the rotational shaft (not shown). Accordingly, the height or angle at which laser is radiated may be easily adjusted. 
         [0034]    The fixing body  130  has therein, an installation hole  132  for fixing the driving motor  120  and motor fixing bolt holes  133 . The driving motor  120  may be installed and fixed in the fixing body  130  through the installation hole  132  and the motor fixing bolt holes  133  by way of a fixing bracket (not shown) 
         [0035]    The fixing body  130  further has a power line inserting hole  134  that allows a power line A connected with the slip ring  150  to connect to the driving motor  120  so that the driving motor  120  may be fed with power. 
         [0036]    The fixing body  130  further has a connection pathway  135  therein, to allow the power line A wired through the power line inserting hole  134  to be easily connected with the driving motor  120 . 
         [0037]    In the device  100  for repelling wild animals and pest birds configured as above, according to the present invention, the support  110  is firmly secured to a ground or floor in an area where the device  100  desires to install. 
         [0038]    In this case, the fixing body  130  has a fixing mechanism  131  on the top surface thereof, and the fixing body  130  is installed at an end of the support  110  by way of the fixing mechanism  131  so that the fixing body  130  faces the ground. 
         [0039]    The rotational body  160  is inserted and installed ink the fixing body  130  so that a portion of the rational body  160  is positioned inside the fixing body  130  while the rest of the rational body  160  is exposed to the outside. 
         [0040]    The laser modules  170  are installed in the exposed part of the rotational body  160 . 
         [0041]    The slip ring  150  is fixed and installed to the rotational body  160  under the rotational body  160 . The slip ring  150  is connected with a power source. 
         [0042]    Now described is a process for repelling pest animals by supplying power to the device  100  for repelling wild animals and pest birds using laser configured as above. 
         [0043]    First, upon power on, the driving motor  120  is powered and driven while the laser modules  170  are simultaneously suppled with power through the slip ring  150  to emit laser. 
         [0044]    When the driving motor  120  is driven, the decelerator  140  connected to the driving shaft  121  is rotated. 
         [0045]    When the decelerator  140  is rotated, the rotational body  160  connected thereto is also rotated, turning around the laser modules  170  provided in the outer side thereof. Accordingly, laser beams may be emitted in all directions. 
         [0046]    The emitted laser beams may keep away pest birds or wild animals. 
         [0047]    In case the trenches  163  are formed in the rotational body  160 , the sliding parts  164  may be slid up and down and stopped in the trenches  163 , adjusting the height at which the laser modules  170  radiate laser. 
         [0048]    As described above, the device for repelling wild animals and pest birds using laser is configured to have the rotational body, rotated by drive of the motor, installed on the support at a predetermined height and the modules for producing laser installed in the rotational body, so as to emit laser in all directions as the motor drives. The device according to the present invention may be installed and used regardless of time or place, e.g., in a farmland, orchard, fish farm, grain silo, highway, or airport, effectively repelling or deterring pest birds or other wild animals.
