Title: Kayak smart propulsion system

Description:
TECHNICAL FIELD 
     The utility model relates to the field of attachment technologies, and more particularly, to a kayak smart propulsion system. 
     BACKGROUND 
     As we all know, with the development of automation and intelligence of fishing kayaks, more and more fishing kayaks are currently propelled by electrical motors, can walk in a straight line automatically, can navigate automatically, and can even fix a fishing spot automatically, so that fishermen can concentrate on fishing. 
     At present, single-propeller propulsion systems are mostly used in the market, which are expensive while being mounted in the front, and complicated while being mounted in the rear, and most of the single-propeller propulsion systems do not have a smart control function. 
     At present, a trolling motor is generally mounted in a middle-front part of a body of the fishing kayak in the market, or the trolling motor is mounted at a quarter of the fishing kayak. The first manner is factory standard, which is generally expensive, while the second manner is to install the trolling motor by users themselves, which is generally complicated and troublesome in a process. 
     Many kayak propulsion systems in the market may encounter a circumstance that a bottom part of the propulsion system will touch a bottom of a river (sea) when the water is shallow to damage the propulsion system. 
     SUMMARY 
     In order to solve the above technical problems, the utility model provides a kayak smart propulsion system, which can be quickly and conveniently contracted, conveniently folded and unfolded, and easily mounted and dismounted, is elastically propelled by a two-propeller propulsion system, can walk in a straight line automatically, can navigate automatically, and can fix a fishing spot automatically. 
     The kayak smart propulsion system of the utility model includes a kayak body, a propulsion system body, two susceptors, two clamps, two motor arms, and two propellers, wherein the two susceptors are mounted at two sides of the kayak body, the propulsion system body is fixed on the two susceptors through the two clamps, two rotating joints are arranged at two sides of the propulsion system body, the two motor arms are respectively connected with the two rotating joints, and the two propellers are respectively mounted on the two motor arms. 
     The kayak smart propulsion system of the utility model further includes two butterfly screws, wherein the two clamps are respectively fixed on two susceptors through the two butterfly screws. 
     According to the kayak smart propulsion system of the utility model, the two clamps are both U-shaped. 
     Compared with the prior art, the utility model has the beneficial effects that: the utility model implements the functions of electric propulsion of the two-propeller propulsion system, automatic walking in a straight line, automatic navigation, and automatic fixing of the fishing spot, is friendly to be mounted on a kayak, and can be conveniently mounted on almost all kayaks by a user to update the kayak of the user into an electric smart kayak. Moreover, the propulsion system can be dismounted at will and mounted on other kayaks in a later stage, can be electrically contracted and lifted very quickly and easily to avoid the two propellers from touching bottom of a river (sea). Moreover, after a depth sensor is mounted, the propulsion system has functions of automatic shallow water warning and motor arm lifting.

     According to the kayak smart propulsion system of the utility model, the mounting manner, the connecting manner or the setting manner of all the above components are all common mechanical manners, and the specific structure, the model and the coefficient index of all the components are all self-provided technologies, which can be implemented as long as the beneficial effects thereof can be achieved, and will not be repeated herein. According to the kayak smart propulsion system of the utility model, unless otherwise stated, the orientation words included in the terms, such as “up, down, left, right, front, back, inside and outside, as well as vertical and horizontal” only represent the orientations of the terms in a normal use state, or are popular names understood by those skilled in the art, and shall not be regarded as limiting the terms. Meanwhile, the sequence nouns, such as “first”, “second”, and “third” do not represent specific numbers and orders, and are merely used for distinguishing names. In addition, the terms “comprise” and “include” or any other variant forms thereof are intended to cover non-exclusive inclusion, so that a process, a method, an article or a device including a series of factors may not only include those factors, but also include other factors which are not listed definitely, or may also include initial factors of the process, the method, the article or the device. 
     The above is only the preferred implementation manner of the utility model.
