DETAILED DESCRIPTION

[0026] Embodiment one, as shown in Figures 1-5 .

[0027] A water gate for an irrigation ditch includes a water gate 2 erected on the top surface of the ditch 1 and a cleaning mechanism 3 coupled to the water gate 2. The cleaning mechanism 3 is used to remove mud and sand deposited on the water-facing side of the water gate 2.

[0028] like Figure 1 As shown, the ditch 1 has a rectangular cross-section, with a horizontal bottom plate 101 at the bottom, vertical side plates 102 on both sides, and an opening at the top, forming a water passage inside, through which irrigation water flows.

[0029] The sluice gate 2 includes a gate plate 201 rotatably connected to the two side plates 102. The gate plate 201 includes an arc-shaped plate body 202 and a cantilever section 203 located at the top of the arc-shaped plate body 202. The arc-shaped convex surface of the plate body 202 is the water-facing surface, and the arc-shaped concave surface of the plate body 202 is the connecting surface. The water-facing surface is in contact with the water, and the cantilever section 203 extends outward in a direction away from the water-facing surface. It should also be emphasized that the bottom end face of the plate body 202 is a connecting surface, which is planar. The width of the gate plate 201 is the same as the width of the water passage, and rubber strips are glued to both sides of the gate plate 201 to enhance the sealing between the gate plate 201 and the side plates 102. The height of the gate plate 201 is greater than the height of the water passage. When the sluice gate 2 is closed, the top of the gate plate 201 is exposed on the upper surface of the side plates 102.

[0030] Mounting seats 207 are provided opposite to each other on the top surface of the two side plates 102. The mounting seats 207 and the side plates 102 are of equal thickness and are fixedly connected by screws. A rotating shaft 204 is rotatably connected between the two mounting seats 207. The mounting seats 207 have shaft holes, the rotating shaft 204 extends into the shaft holes, and a bearing (not shown in the figure) is provided between the rotating shaft 204 and the shaft holes. The rotating shaft 204 and the mounting seats 207 are rotatably connected by the bearing.

[0031] The rotating shaft 204 and the gate plate 201 are fixedly connected by two sets of connectors arranged parallel to each other along the axis of the rotating shaft 204. In this embodiment, each set of connectors includes two fixing rods 205 spaced apart along the circumference of the rotating shaft 204. One end of the fixing rod 205 is welded to the connecting surface of the gate plate 201, and the other end of the fixing rod 205 is welded to the outer side of the rotating shaft 204. A reinforcing rod 206 is welded between the waists of the two fixing rods 205. The reinforcing rod 206 further enhances the stability and strength of the connector structure, thereby ensuring the stability between the rotating shaft 204 and the gate plate 201.

[0032] like Figure 1 As shown, a motor 208 is provided at one end of the rotating shaft 204. The output shaft of the motor 208 is connected to the rotating shaft 204 through a coupling to achieve transmission. The motor 208 is fixedly connected to the outer wall of the side plate 102 by screws.

[0033] When it is necessary to close the sluice gate 2, the motor 208 is started. Driven by the motor 208, the rotating shaft 204 and the gate plate 201 rotate synchronously. When the gate plate 201 rotates towards the bottom plate 101 until the plate body 202 contacts the bottom plate 101, the connecting surface of the plate body 202 is in a vertical state, and the cantilever section 203 of the gate plate 201 is in a horizontal state, thus blocking the water passage through the gate plate 201. In order to further improve the working stability of the sluice gate 2, horizontally protruding limiting blocks 103 are provided at the bottom of the two side plates 102. The limiting blocks 103 are integrally formed with the side plates 102, and the connecting surface of the plate body 202 abuts against the limiting blocks 103, providing support and limiting function for the gate plate 201.

[0034] By setting the main plate 202 of the gate 201 to an arc shape, on the one hand, the arc structure itself has good bending and torsion resistance and can withstand greater water pressure; on the other hand, compared with flat gates, there is no need to reserve lifting space, the space occupies less, and the layout is flexible.

[0035] However, in actual operation, a large amount of particulate impurities such as silt and gravel (hereinafter collectively referred to as silt) will be deposited in front of the gate 201. This will not only increase the frictional resistance encountered during the opening and closing of the sluice gate 2, but also create uneven pressure on the bottom of the gate 201, causing the gate 201 to deform. In addition, the silt deposited at the bottom of the water is not easy to remove, and will still flow into the farmland after the gate is opened to release water. The deposition of fine silt will block soil pores, reduce aeration and permeability, lead to soil hardening, and affect root development; coarse silt (such as gravel) will cover the surface layer, destroy the soil aggregate structure, and reduce the water and fertilizer retention capacity.

[0036] Based on this, in this embodiment, a clearing mechanism 3 is coupled to the sluice gate 2, such as... Figures 2-5 As shown, the clearing mechanism 3 includes multiple flow channels 301 evenly spaced along the width of the gate 201 inside the gate 201. The inlet 302 of the flow channel 301 is located at the bottom of the water-facing side of the plate 202, and the outlet 303 of the flow channel 301 is located at the end face of the free end of the cantilever section 203. It is worth noting that the bottom surface of the inlet 302 slopes downwards towards the water-facing side, and a transition block 304 is provided below the inlet 302, which is in contact with the bottom surface of the inlet 302. Specifically, the length of the transition block 304 is the same as the width of the gate 201, the cross-section of the transition block 304 is triangular, the bottom surface of the transition block 304 is in contact with the bottom plate 101, one inclined surface of the transition block 304 is in contact with the water-facing side of the plate 202, and the other inclined surface of the transition block 304 is in contact with the inlet 302, with both having the same degree of inclination.

[0037] The space at the angle between the plate 202 and the bottom plate 101 is narrow and is a dead angle. By setting the transition block 304, on the one hand, the dead angle between the plate 202 and the bottom plate 101 is filled to prevent the accumulation of mud and sand. On the other hand, it plays a connecting role between the bottom plate 101 and the inlet 302, so that water and mud and sand can enter the interior of the flow channel 301 along the transition block 304 and the inlet 302.

[0038] An air inlet 305 communicating with the flow channel 301 is provided on the connecting surface of the plate 202. The air inlet 305 gradually slopes upward from the outside to the inside and is located at the top of the flow channel. An exhaust pipe 306 is fitted inside the air inlet 305 and the two are welded together. The axis of the exhaust pipe 306 coincides with the axis of the air inlet 305. It should be noted in detail that in this embodiment, the exhaust pipe 306 is made of stainless steel, which has high strength and strong corrosion resistance.

[0039] A mounting plate 312 is also provided on the top surface of the side plate 102 away from the gate plate 201. The mounting plate 312 spans both sides of the side plate 102 and is fixedly connected to them by screws. A gas compressor 307 and a gas-gathering pipe 308 are connected to each other on the mounting plate 312, with a gap between them. Specifically, the gas compressor 307 is fixed to the mounting plate 312 by screws, and the gas-gathering pipe 308 is welded to the mounting plate 312. The gas-gathering pipe 308 extends in the same direction as the width of the water passage. The gas-gathering pipe 308 is hollow inside and closed at both ends. The exhaust port of the gas compressor 307 is connected to one end of the gas-gathering pipe 308 through a pipe.

[0040] The air-gathering pipe 308 and the exhaust pipe 306 are connected by an air guide pipe 309. Specifically, the air-gathering pipe 308 has multiple air guide holes evenly spaced along the axial direction. Each air guide hole corresponds to an air inlet 305. The air guide holes and the exhaust pipe 306 are connected by an air guide pipe 309. One end of the air guide pipe 309 is inserted into the exhaust pipe 306 and the connection between the two is glued and fixed. The other end of the air guide pipe 309 is inserted into the air guide hole and the connection between the two is also glued and fixed.

[0041] A collection trough 310 is also provided on one side of the outlet 303 of the flow channel 301. The collection trough 310 is located below the outlet 303. The two ends of the collection trough 310 are welded with fixing ears 311, which overlap the top surface of the side plate 102 and are fixedly connected to the side plate 102 by screws. It is worth emphasizing that the bottom plate of the collection trough 310 has multiple filter holes, and the bottom plate of the collection trough 310 is covered with a layer of filter cloth (such as polyester filter cloth).

[0042] When sluice gate 2 is closed, water and sediment enter the flow channel 301 through transition block 304 and inlet 302 under water pressure. According to the principle of communicating vessels, the water level in flow channel 301 is the same as the external water level, so the water and sediment in flow channel 301 cannot be discharged through outlet 303. Therefore, gas compressor 307 is turned on, and the high-pressure gas generated by gas compressor 307 enters the flow channel 301 through gas gathering pipe 308, gas guiding pipe 309 and exhaust pipe 306. Under the air lift effect of high-pressure gas, the water and sediment in flow channel 301 rise to the top of flow channel 301 and are discharged through outlet 303. The discharged water and sediment fall into collection tank 310. The water re-enters the water passage space through filter cloth and filter holes, while the sediment remains in collection tank 310, realizing the collection and removal of sediment.

[0043] By setting up the cleaning mechanism 3, the sediment deposited in front of the gate 201 can be continuously collected and removed. On the one hand, it can effectively reduce the resistance encountered during the opening and closing of the gate 2 and alleviate the uneven pressure on the gate 201. On the other hand, it removes the sediment in the water body from the source and prevents the sediment from entering the farmland with the water flow during the subsequent opening and releasing of water, thus affecting the soil planting environment.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
