[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 , Figure 2 and Figure 3As shown, a filtering device for irrigation canals in fish-rice symbiotic fields includes a shell 1, a drainage component 2 is fixedly connected to the right side of the inner cavity of the shell 1, a disinfection component 3 is fixedly connected to the left side of the outer surface of the drainage component 2, a filtering component 4 is fixedly connected to the middle of the rear side of the disinfection component 3, a collecting component 6 is rotatably connected to the right end of the filtering component 4, and a flushing component 5 is fixedly connected to the left side of the inner cavity of the shell 1.

[0035] When the operator is using the device, the device needs to be installed parallel to the water channel. Furthermore, when the rice needs to be harvested and the paddy field needs to be filled with water, the operator only needs to turn the drainage component 2 to open the doors on both sides to drain the water flow in the water channel. Therefore, when the drainage components 2 on the front and rear sides are opened, the drainage component 2 located on the front side will block the water flow in the water channel, so that the water flow in the water channel enters the inner cavity of the shell 1, and then the water entering the inner cavity of the shell 1 will be drained by the power source inside the disinfection component 3, so as to disinfect and sterilize it, and further discharged into the filter component 4. Through the cooperation between the filter component 4 and the flushing component 5, the drained water is filtered, and the larger residue will be transported by the filter component 4 to the inner cavity of the collection component 6, so as to complete the filtration of the water, and then discharged into the paddy field for planting rice or releasing fish fry again;

[0036] Furthermore, by setting up a drainage component 2 to drain the water in the drainage channel and cooperate with the disinfection component 3, it helps to purify the water quality, create a healthier living environment for aquatic organisms such as carp, and promote the growth and reproduction of fish. Further, by setting up a filtering component 4 and a collecting component 6 to cooperate, the water after disinfection can be filtered and collected again, thereby preventing the materials generated during the disinfection process from flowing into the fish field and causing environmental impacts.

[0037] Further, in order to achieve the purpose of draining the water in the water and disinfecting the drained water at the same time;

[0038] Please refer to Figure 4 , Figure 5 and Figure 6As shown, the drainage component 2 includes a shell 21, the left side of the outer surface of the shell 21 is fixedly connected to the right side of the disinfection component 3, the top wall and the bottom wall of the inner cavity of the shell 21 are fixedly connected to two fixed blocks 23, the middle of the inner surface of the two fixed blocks 23 on the same side are slidably connected to a sliding rod 22, the middle of the left side of the inner cavity of the shell 21 is rotatably connected to a rotating column 24, the middle of the outer surface of the rotating column 24 is fixedly connected to a matching gear 25, the right end of the rotating column 24 passes through the right part of the inner surface of the shell 1 and extends to the outer surface of the shell 1 and is fixedly connected to a rotating handle 26, the ends of the two sliding rods 22 away from each other are slidably connected to a drainage plate 27, and the two drainage The plates 27 are provided with slide rails 28 that cooperate with the two sliding rods 22 on the sides where they are close to each other. The disinfection component 3 includes a fixed plate 31. The bottom right side of the fixed plate 31 is fixedly connected to the middle of the outer surface of the shell 21. The bottom front side of the fixed plate 31 is fixedly connected to a filter plate 32. The upper end of the filter plate 32 is fixedly connected to a water pump 34. The input end of the water pump 34 is fixedly connected to a suction pipe 33. The output end of the water pump 34 is fixedly connected to a drain pipe 35. The upper end of the drain pipe 35 is fixedly connected to a separation plate 36. The middle part of the upper side of the separation plate 36 is fixedly connected to a pumping pipe 37. The upper left part of the fixed plate 31 is fixedly connected to a pumping pipe 2 38.

[0039] Furthermore, when the operator is injecting water into the rice field, the operator needs to rotate the rotating handle 26, so that when the rotating handle 26 is rotated, the rotating column 24 fixedly connected to the left end thereof will be driven to rotate, so that the matching gear 25 fixedly connected to the outer surface cooperates with the two sliding rods 22, thereby driving the two sliding rods 22 to move in the opposite direction, thereby driving the two drainage plates 27 to open along the corresponding slide rails 28, and then the water in the drainage channel will be blocked by the drainage plate 27 connected to the front side, so that the water in the drainage channel enters the inner cavity of the shell 1, and at this time, the filter plate 32 fixedly installed in the inner cavity of the shell 1 Larger objects will be filtered, and the water pump 34 fixedly installed above will extract them through the suction pipe 33 fixedly connected to the input end, and then discharge them into the upper part of the separation plate 36. Furthermore, by placing bamboo charcoal and volcanic rocks on the left and right sides of the separation plate 36, the bacteria in the canal will be disinfected and preliminarily filtered. After the water volume on the right side of the separation plate 36 is higher than the water pump 37, the water pump 37 will pump the water on the upper right side of the separation plate 36 to the left side of the separation plate 36 through the siphon principle, and then the water in the canal will be disinfected again, thereby completing the purpose of draining the water in the canal and disinfecting it at the same time;

[0040] In addition, it should be noted that when disinfecting bacteria in the canal, it is only necessary to place an appropriate amount of bamboo charcoal and volcanic stone on the left and right sides of the separation plate 36, and a filter plate is also required to be placed at the connection between the right side of the separation plate 36 and the drain pipe 35 to prevent the disinfecting material from falling into the inner cavity of the drain pipe 35. Further disinfecting materials can also be selected from rattan cotton or ceramsite and other materials with disinfecting effects;

[0041] Furthermore, by adding an appropriate amount of disinfectant material on the left and right sides of the separation plate 36, it can be ensured that the water flowing into the rice field does not contain bacteria that are harmful to the fry or the rice field, thereby improving the yield and quality of rice and fry. Further, by turning the rotating handle 26 to control the opening or closing of the drainage plate 27 rotatably connected to the shell 1 on the front and rear sides, the device can drain the water in the canal, thereby improving the irrigation efficiency of the canal.

[0042] Embodiment 2: Based on Embodiment 1, this embodiment achieves the purpose of filtering and collecting the water after disinfection;

[0043] For further information, please refer to Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the filter assembly 4 includes a filter barrel 41, and the middle parts of the left and right ends of the filter barrel 41 are fixedly connected with fixed pipes 43, and the middle part of the right side of the filter barrel 41 is provided with a support groove 42. The inner surface of the right fixed pipe 43 is closely attached to a sewage pipe 44, and the outer surface of the left fixed pipe 43 is closely attached to a support assembly 45. The left and right sides of the support assembly 45 are fixedly connected with support plates 1 46. The support assembly 45 includes a shell 2 451. The left wall of the inner cavity of the shell 2 451 has four fixed columns 453 in an annular array. The middle part of the outer surface of the four fixed columns 453 is rotatably connected with a gear. The outer surfaces of the four meshing wheels 452 are tightly attached to the middle of the outer surface of the left fixed tube 43. The bottom of the limiting plate 61 is provided with a plurality of drainage holes communicating with the inner cavity of the collecting bin 66. The upper part of the diverter plate 63 and the upper part of the waterproof shell 64 are inclined. A motor is fixedly installed in the inner cavity of the waterproof shell 64. The output end of the motor is fixedly connected to the transmission shaft through a coupling. The fixed tube 43 on the right is connected to the transmission shaft with a belt wrapped around it. The collecting assembly 6 includes a limiting plate 61. The front end of the limiting plate 61 is fixedly connected to the rear end of the fixing plate 31. The middle of the left side of the limiting plate 61 is fixed. The bottom end of the limit plate 61 is fixedly connected with a matching column 62, and the bottom end of the limit plate 61 is fixedly connected with an inclined plate 65. The upper right part of the inclined plate 65 is fixedly connected with a diverter plate 63, and the left side of the diverter plate 63 is fixedly connected with a waterproof shell 64. The middle right part of the limit plate 61 is fixedly connected with a collecting bin 66. The output ends of the two matching columns 62 are rotatably connected with a rotating wheel. The outer surfaces of the two rotating wheels are matched with the supporting groove 42. The right side of the collecting bin 66 is rotatably connected with two trap doors. The flushing assembly 5 includes a submersible pump 51. The bottom end of the submersible pump 51 is fixedly connected to the left rear of the inner cavity of the shell 1. The output of the submersible pump 51 An output pipe 52 is fixedly connected to the output end, and two fixed blocks 53 are fixedly connected to the outer surface of the output pipe 52. The left sides of the two fixed blocks 53 are fixedly connected to the left wall of the inner cavity of the shell 1, and two support plates 54 are fixedly connected to the upper side of the outer surface of the output pipe 52. A plurality of sprinkler heads 55 are fixedly connected to the upper side of the outer surface of the output pipe 52. The right side of the outer surface of the sewage pipe 44 is fixedly connected to the middle part of the collecting component 6. The inner surface of the sewage pipe 44 is inclined. The right end of the sewage pipe 44 is communicated with the collecting component 6. The inner surface of the fixed pipe 43 on the left is communicated with the inner cavity of the water pumping pipe 38.

[0044] Furthermore, when the disinfected water flows into the inner cavity of the filter barrel 41 through the suction pipe 38, the motor in the inner cavity of the device waterproof shell 64 will be started, thereby driving the filter barrel 41 to rotate as a whole through the belt connected to the output end, thereby filtering the disinfected water source, and then, through the inclined plate 65, the filtered water flows out from the left side of the rear end of the fixed plate 31. After the submersible pump 51 contacts the filtered water, it will be controlled by the internal induction switch to start automatically, and the filter barrel 41 will be driven by the outer surface of the output pipe 52. The plurality of water spray heads 55 are fixedly connected to the bottom of the filter barrel 41, and the surface of the filter barrel 41 is cleaned. The impurities washed down will fall into the inner cavity of the sewage pipe 44, and then be brought into the inner cavity of the collection bin 66 by the sewage pipe 44, while the impurities not washed down will wait for the next flushing. The water that further falls into the inner cavity of the collection bin 66 will be discharged through the drainage hole opened at the bottom of the limit plate 61, thereby avoiding the operator from increasing the workload when cleaning the collection bin 66. After the water change is completed, the operator only needs to reversely rotate the rotating handle 26 again to control the two drainage plates 27 to close;

[0045] It should be further explained that the water pump 34 and the submersible pump 51 in this solution and the controller inside the submersible pump 51 are all conventional designs in the prior art, wherein the working principle of the water pump 34 is as follows: the water pump 34 utilizes the power generated by the internal power source to convert it into the power of the liquid, thereby generating the force of flow. When the built-in power source is started, the impeller starts to rotate, thereby sucking the liquid into the pump casing, forming a vacuum or negative pressure at the inlet, so that the liquid is sucked in; a slight positive pressure is formed at the exhaust nozzle to push the liquid out, and finally, the liquid is transported from the low-pressure area to the high-pressure area, thereby achieving the purpose of pumping and transporting water;

[0046] The working principle of the submersible pump 51 is as follows: after receiving the induction from the internal sensor, the impeller will rotate at a high speed, and the liquid will rotate with the blades, and will fly away from the impeller and eject outward under the action of centrifugal force. The ejected liquid will gradually slow down in the diffusion chamber of the pump casing, and the pressure will gradually increase, and then it will flow out from the discharge pipe at the pump outlet. At this time, a vacuum low-pressure area with neither air nor liquid is formed at the center of the blades because the liquid is thrown to the surroundings. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface. In this way, the liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe;

[0047] Furthermore, by providing a water spray head 55 fixedly connected to the upper portion of the outer surface of the output pipe 52 to cooperate with the outer surface of the filter barrel 41, when the filter barrel 41 filters the disinfected water, the disinfection material attached to the inner cavity of the filter barrel 41 can be cleaned up, thereby avoiding clogging of the filter barrel 41 by the disinfection material, thereby extending the service life of the filter barrel 41. Furthermore, by providing an inclined inner surface of the sewage pipe 44, the disinfection impurities flushed down by the water spray heads 55 can be transported to the inner cavity of the collection bin 66, so that the operator can collect and clean them.

[0048] In addition, it should be further explained that any circuit connection in this device is a conventional design in the prior art, and the specific situation shall be subject to actual production, and this solution will not be elaborated in detail.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
