[0002] In agricultural production, water conservancy irrigation is a key link to ensure the healthy growth of crops and achieve high and stable yields. Among them, water conservancy irrigation canals are important carriers for conveying irrigation water. Existing water conservancy irrigation canals are provided with interception gratings made of corrosion-resistant metal materials or high-strength engineering plastic materials at the water inlet of the irrigation canal or key node positions to intercept impurities in the water body and prevent the water conservancy irrigation canal from being blocked.

[0029] Among them, the cleaning structure also includes a positioning mounting plate 101 and a first filter screen 102; a plurality of positioning mounting plates 101 are provided, and the plurality of positioning mounting plates 101 are respectively fixedly connected to the lower end surfaces of a plurality of positioning connecting ear plates 106, and the plurality of positioning mounting plates 101 are bolted to each other; a plurality of first filter screens 102 are provided, and the plurality of first filter screens 102 are respectively fixedly connected to the middle parts of the plurality of positioning mounting plates 101.

[0030] Among them, the cleaning structure also includes a height adjustment screw rod 108 and a synchronous transmission structure 109; there are four height adjustment screw rods 108, and the four height adjustment screw rods 108 are evenly distributed and rotatably connected to the front and rear sides of the irrigation channel body 1; there are two synchronous transmission structures 109, and the synchronous transmission structure 109 is a synchronous belt transmission mechanism, and the two front height adjustment screw rods 108 and the two rear height adjustment screw rods 108 are respectively connected through a synchronous transmission structure 109.

[0031] Among them, the cleaning structure further includes a limit connecting plate 107 and a second filter screen 110; there are two limit connecting plates 107, and the two limit connecting plates 107 are respectively threadedly connected to the two front height adjustment screw rods 108 or the two rear height adjustment screw rods 108; there are two second filter screens 110, and the two second filter screens 110 are respectively fixedly connected to the lower parts of the two limit connecting plates 107.

[0034] The specific usage method and function of this embodiment: When irrigation is required for farmland, water will flow along the main body 1 of the irrigation canal. At this time, the second filter screen 110 will filter impurities in the water body. When the water is flowing, it will push the hydraulic driving wheel 104 and the positioning and mounting rotating shaft 103 to rotate. When the positioning and mounting rotating shaft 103 rotates, it drives the water body stirring paddle 105 to rotate. At this time, the water body stirring paddle 105 will stir the water body and change the flow direction of the water body. The first filter screen 102 can prevent impurities carried in rainwater or impurities blown by the wind from falling into the water conservancy irrigation canal. After some of the first filter screens 102 are damaged, the bolts installed on the positioning mounting plate 101 and the positioning connecting ear plate 106 can be removed to replace the damaged first filter screen 102 separately. When there is a large accumulation of impurities, rotate the height adjustment screw rod 108 to move the limit connecting plate 107 and the second filter screen 110 upward, and pull out the impurities accumulated at the arc-shaped collecting plate 111 from the water conservancy irrigation canal. The synchronous transmission structure 109 can make the height adjustment screw rods 108 on both sides rotate simultaneously. The falling prevention baffle 112 can reduce the falling of impurities during the movement of the arc-shaped collecting plate 111. The limit water baffle 113 can reduce the diameter of the water conservancy irrigation canal near the second filter screen 110. When the water flows through the second filter screen 110, the reduced flow path makes the water flow speed increase, and the resistance of the second filter screen 110 to the water restores the water flow speed.

[0035] Embodiment Two: As Figures 6 to 8 shown below: Based on the first embodiment, it further includes a limiting structure; the limiting structure is arranged inside the main body 1 of the irrigation canal.

[0036] Among them, the limiting structure includes a first reset elastic member 401, a guiding connecting plate 402, and a limiting traction rope 403; a plurality of first reset elastic members 401 are provided, and the sliding bearing plate 4 is elastically connected to the main body 1 of the irrigation canal through the plurality of first reset elastic members 401; a plurality of guiding connecting plates 402 are provided, and the plurality of guiding connecting plates 402 are evenly distributed and fixedly connected to the left and right sides of the sliding bearing plate 4, and the plurality of guiding connecting plates 402 are respectively slidably connected to the upper and lower two limiting guiding plates 3; a plurality of limiting traction ropes 403 are provided, and the plurality of limiting traction ropes 403 are respectively fixedly connected to the outer sides of the plurality of guiding connecting plates 402, and the plurality of limiting traction ropes 403 pass through the main body 1 of the irrigation canal and are respectively fixedly connected to the two power transmission rotating shafts 5.

[0037] Among them, the limiting structure further includes a reset scroll spring 501 and a second reset elastic member 701; a plurality of reset scroll springs 501 are provided, and the two power transmission rotating shafts 5 are elastically connected to the main body 1 of the irrigation canal through the plurality of reset scroll springs 501; a plurality of second reset elastic members 701 are provided, and the plurality of sliding mounting seats 7 are elastically connected to the main body 1 of the irrigation canal through the plurality of second reset elastic members 701.

[0038] The specific usage mode and function of this embodiment: When cracks appear in the main body 1 of the irrigation canal, water will flow into the inside of the main body 1 of the irrigation canal along the cracks. At this time, the leak-proof water-receiving film 2 will intercept the leaked water, so that the water flow is blocked above the leak-proof water-receiving film 2. When the water accumulates more, the gravity of the water will cause the sliding bearing plate 4 to compress the first reset elastic member 401 and slide downward along the limiting guiding plate 3. The guiding connecting plate 402 will guide the sliding of the sliding bearing plate 4. When the sliding bearing plate 4 and the guiding connecting plate 402 slide, they will pull the limiting traction rope 403, so that the limiting traction rope 403 pulls the power transmission rotating shaft 5 to rotate. When the power transmission rotating shaft 5 rotates, it will drive the position-limiting push plate 6 to rotate, so that the position-limiting push plate 6 pushes the sliding mounting seat 7 and the water leakage warning plate 8 to compress the second reset elastic member 701 and slide upward, so that the water leakage warning plate 8 is higher than the main body 1 of the irrigation canal, reminding the user that cracks have appeared in the main body 1 of the irrigation canal. When repairing the main body 1 of the irrigation canal, the water above the leak-proof water-receiving film 2 is pumped out. At this time, the first reset elastic member 401, the reset scroll spring 501, and the second reset elastic member 701 will drive the sliding bearing plate 4, the power transmission rotating shaft 5, and the sliding mounting seat 7 to reset.
