[0027] The following is combined with Figure 1 To Attachment Figure 6 And specific embodiments further describe the present application in detail. Embodiment 1:

[0028] In the present application, an anti-debris sluice structure for irrigation is disclosed, which includes a gate 10, a sluice base 20 for installing the gate 10, and a filtering mechanism 30, wherein the structure of the sluice base 20 is in a shape suitable for adapting to the cross-section of an irrigation channel, such as a "concave" shape, the gate 10 can be movably installed on the inner side of the sluice base 20, and the sluice base 20 and the gate 10 are connected to a driving device such as a motor through a transmission mechanism, so that the gate 10 can reciprocate in one direction and can open or close the irrigation channel formed by the sluice base 20 and the irrigation channel; the above-mentioned filtering mechanism 30 is located in front of or behind the water-facing surface of the gate 10, and is used to intercept and process sediment and floating garbage in the water flow, and the filtering mechanism 30 includes a filter plate 31 and a sediment collection tank, Slots 21 are provided on the inner sides of the two opposite side walls of the sluice base 20 from the top to the bottom, and the filter plate 31 is inserted into the slots 21. The water-facing surface of the filter plate 31 is provided with a first filter area 311 and a second filter area 312 in sequence from bottom to top (i.e., one of the directions away from the bottom of the sluice base 20). A plurality of filter holes are provided in the first filter area 311 and the second filter area 312, and the mesh number of the filter holes in the first filter area 311 is greater than the mesh number of the filter holes in the second filter area 312 (i.e., the filter holes in the first filter area 311 are more and have smaller apertures than those in the second filter area 312); the bottom surface of the filter plate 31 (i.e., the surface facing the bottom of the sluice base 20) is fixedly or detachably connected to the above-mentioned sediment collection tank by welding, snap connection, plug-in, etc.

[0029] Specifically, the above-mentioned method of driving the gate 10 to move to achieve the flow or stop of water in the irrigation channel is one of the conventional technical means, which is not a necessary technical means relied on by the present application to solve the technical problem, and will not be described in detail hereinafter.

[0030] When the above-mentioned anti-debris sluice structure for irrigation is used, the gate 10 is controlled to open the irrigation channel, and the filter plate 31 filters the water flowing through the channel. The first filter area 311 finely filters the water layer close to the bottom of the channel, and intercepts the sediment moving with the water flow in front of the water surface of the filter plate 31; the second filter area 312 coarsely filters the water layer away from the bottom of the channel, and intercepts garbage such as branches and plastic bags drifting with the water flow in front of the water surface of the filter plate 31.

[0031] The above-mentioned irrigation anti-clutter sluice structure can achieve at least the following technical effects:

[0032] When water flows through the above-mentioned filtering mechanism 30, the silt is intercepted by the first filtering area 311 and flows into the silt collecting tank below the first filtering area 311, which can not only prevent the filter screen from being blocked by silt in the prior art, resulting in reduced water flow efficiency, but also prevent a large amount of silt in the water flow from entering the irrigation area, thereby alleviating the problem of changes in farmland soil quality; the second filtering area 312 intercepts the floating garbage above the water flow, and the mesh number of the filtering holes in the second filtering area 312 is smaller than the mesh number of the filtering holes in the first filtering area 311, which can ensure that sufficient irrigation water enters the irrigation area, and the filter plate 31 can be taken out of the slot 21 to quickly clean up the floating garbage and silt, thereby ensuring the convenience of maintenance of the anti-miscellaneous sluice structure.

[0033] In addition, the present application also provides some more specific implementation methods to improve the above-mentioned irrigation anti-debris sluice structure.

[0034] Furthermore, in order to prevent the floating garbage from approaching the surface of the filter plate 31 under the impact of the water flow and causing the filter holes of the second filter area 312 to be blocked, a first sewage interception area 313 is provided on the upper side of the second filter area 312 (i.e., away from the first filter area 311), and a plurality of first synapses 314 are provided in the first sewage interception area 313.

[0035] Specifically, the first synapse 314 is in the shape of a filament, a column or a cone, and extends in front of the water-facing surface of the filter plate 31, so that the floating garbage is pushed away from the surface of the second filter area 312, so that the filter holes of the second filter area 312 are not easily completely blocked by garbage, thereby ensuring that the water flow efficiency can be maintained at a level that meets irrigation needs.

[0036] Embodiment 2, based on the above embodiment 1, has the following differences compared with embodiment 1:

[0037] In order to prevent the water flow from repeatedly impacting the filter plate 31 and causing damage to the filter plate 31 , the filtering mechanism 30 further includes a reinforcing frame 33 , and the filter plate 31 is a rubber filter plate 31 , which is disposed in the reinforcing frame 33 .

[0038] Specifically, a reinforcing frame 33 made of a metal material such as aluminum alloy is selected and arranged around the rubber filter plate 31 to reinforce the rubber filter plate 31. When the rubber filter plate 31 is inserted into the slot 21, the reinforcing frame 33 contacts the inner wall of the slot 21 to avoid deformation of the edge of the rubber filter plate 31 and wear caused by contact with the slot 21. The rubber filter plate 31 is punched from bottom to top to form a first filter area 311 and a second filter area 312.

[0039] When the above-mentioned anti-debris sluice structure for irrigation is used, the first filter area 311 and the second filter area 312 of the rubber filter plate 31 can undergo elastic deformation under the impact of water flow, which can effectively alleviate the vibration and damage caused by the impact of water flow, and is not easily blocked by fine impurities, which helps to maintain a high filtration efficiency for a long period of time for the filter mechanism 30; and the reinforcing frame 33 can prevent the rubber filter plate 31 from deforming around, while reducing vibration and avoiding contact and wear between the filter plate 31 and the slot 21, so that the rubber filter plate 31 and the slot 21 have a higher degree of tightness, preventing pollutants from entering the irrigation area from the joint between the filter plate 31 and the slot 21.

[0040] Furthermore, in order to improve the maintenance convenience of the filter plate 31, a handle 331 is provided on the top of the reinforcement frame (ie, the side away from the sediment collection tank).

[0041] When the above-mentioned debris-proof water gate structure for irrigation is used, the operator can directly lift the filter plate 31 from the slot 21 through the handle 331 so as to clean the filter plate 31 or perform other maintenance operations.

[0042] Furthermore, the water flow continuously impacts the filter plate 31, causing the filter plate 31 to vibrate and wear, which easily causes a gap between the filter plate 31 and the slot 21, resulting in impurities such as mud and sand flowing into the irrigation area. To avoid the above situation, the filter plate 31 is respectively provided with sealing strips 315 on two opposite sides, and the sealing strip 315 is provided with a plurality of mud and sand collecting grooves 323151 along the extension direction of the slot 21, and the plurality of mud and sand collecting grooves 323151 are evenly distributed relative to the water-facing surface and the water-retaining surface of the filter plate 31.

[0043] Specifically, the sealing strip 315 is a rubber strip with low hardness and high ductility and a silicone strip; the sediment collection groove 323151 penetrates the sealing strip 315 from top to bottom and is arranged on the inner side of the sealing strip 315, and the sediment collection groove 323151 is distributed on the front and rear sides of the filter plate 31.

[0044] When using the above-mentioned anti-debris sluice structure for irrigation, the low-hardness, high-ductility sealing strip 315 can fill the gap between the filter plate 31 and the slot 21 to ensure the sealing between the edge of the filter plate 31 and the slot 21; and the sediment collection trough 323151 can reduce the impact of water flow on the filter plate 31, avoiding the deformation and wear of the sealing strip 315 caused by the vibration of the filter plate 31.

[0045] On the basis of providing the above-mentioned sealing strip 315, in order to further improve the sealing performance of the sealing strip 315 and the convenience of maintenance of the filter plate 31, a plurality of extrusion rollers 211 are provided in the above-mentioned slot 21 along the height direction, and the extrusion rollers 211 are rotatably connected to the inner wall of the slot 21. The extrusion rollers 211 are used to extrude the above-mentioned sealing strip 315 so that the side of the sealing strip 315 facing away from the extrusion rollers 211 is tightly fitted with the inner wall of the slot 21.

[0046] Specifically, the contour of the extrusion roller 211 is circular or elliptical, etc. During the process of inserting the filter plate 31 along the slot 21, the tread of the extrusion roller 211 is in close contact with the sealing strip 315 and presses the sealing strip 315 toward the other side of the slot 21 during rolling. When the above-mentioned anti-debris sluice structure for irrigation is used, even if the filter plate 31 is impacted by a strong water flow, it is not easy to cause a gap between the sealing strip 315 and the slot 21 due to vibration; and during the process of inserting and removing the filter plate 31, one side of the sealing strip 315 is in rolling contact with the extrusion roller 211, which can save manpower and make it easy for the operator to install or remove the filter plate 31 and perform de-debris maintenance on the filter plate 31.

[0047] Furthermore, in order to prevent the silt from being impacted by the water flow and clogging the filter holes of the first filter area 311, a guide slope 321 is provided on the water-facing surface of the filter plate 31 in the silt collection trough, and the connection between the slope surface of the guide slope 321 and the bottom surface of the silt collection trough forms an obtuse angle.

[0048] When the above-mentioned irrigation debris-proof sluice structure is used, under the guidance of the above-mentioned guide slope 321, the silt is guided downward by the guide slope 321 and collected in the silt collection tank before reaching the filtering holes of the filter plate 31.

[0049] Furthermore, a receiving groove 22 is provided on the bottom surface of the sluice base 20 between the slots 21 , and the receiving groove 22 is used to place the sediment collection groove, so that the side of the diversion slope 321 away from the water-facing surface of the filter plate 31 is in the same horizontal plane as the bottom surface of the sluice base 20 .

[0050] Specifically, the upper side of the diversion slope 321 is at the same horizontal plane as the bottom surface of the sluice base 20, so that the sediment collection trough is located below the bottom surface of the sluice base 20. In the process of collecting sediment, the sediment collection trough is not in the water flow channel in the channel, which reduces the loss of water flow velocity and enables the flow velocity in the channel to meet the requirements of irrigation efficiency.

[0051] Furthermore, as the amount of sediment accumulated in the sediment collection trough gradually increases, in order to prevent the sediment that has not been removed in time from surging up under the impact of water flow and causing pollution to the filter holes of the first filter area 311, the bottom surface of the above-mentioned sediment collection trough is provided with a second sewage interception area 322, and a plurality of second synapses 323 are provided in the second sewage interception area 322.

[0052] Specifically, the second synapse 323 has the same or similar shape as the first synapse 314, and the gaps between the second synapses 323 enable the second sewage interception area 322 to intercept more sediment, and can effectively prevent a large amount of sediment at the bottom of the sediment collection tank from surging and polluting the first filter area 311, thereby ensuring that the filter holes of the first filter area 311 can maintain the filtration efficiency within the set period.

[0053] Based on the further limitation of the construction or implementation mode in the above-mentioned embodiments, the anti-debris sluice structure for irrigation can be further improved in terms of the contact sealing between the filter plate 31 and the sluice base 20, the maintenance convenience of the filter plate 31, the service life and impact resistance, etc., so that the structure can meet the needs of channel water diversion irrigation.

[0054] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
