Description

Technical Field

[0001] The invention relates to the technical field of agricultural water saving, and in particular to a prefabricated assembled culvert gate and a method of using the culvert gate for irrigation ditches. Background Art

[0002] Irrigation canals are waterways that connect irrigation water sources and irrigated land. They transport and distribute the water drawn from the water sources to various parts of the irrigation area. Within an irrigation area, irrigation canals are divided into five levels: main canals, branch canals, ditches, agricultural canals, and small ditches according to the size of the controlled area. Irrigation areas with complex terrain and large areas can also add multiple levels of canals such as main trunks, branch trunks, branches, and ditches. Irrigation areas with smaller areas can reduce the number of canal levels. The longitudinal and cross-sectional designs of the canals should be based on the design irrigation flow and design irrigation water level.

[0003] Chinese patent CN118668654A discloses a self-maintaining culvert structure for a culvert water conservancy project. The structure is sleeved on the bottom end of a first vertical plate through a protective frame, and coarse filters on both sides are used when the gate baffle is opened to prevent floating objects in the reservoir from clogging the culvert, thereby improving the flow efficiency of water discharge when the reservoir is opened. The second servo motor is used to drive the second screw rod through the rotation, so that the linkage sleeve drives three groups of fine filters away from the ports of the first drain port, the second drain port and the third drain port, thereby ensuring the flow efficiency of the drain port.

[0004] When the above-mentioned prefabricated assembled culvert is in use, floating objects in the river water are intercepted by coarse and fine filters to ensure the flow efficiency when the gate is opened to release water. As time goes by, the debris intercepted in the river water will accumulate in front of the filter, causing most of the filter area to be blocked, thereby reducing the flow efficiency of the river water and affecting the irrigation effect.

[0015] To achieve the above object, the present invention provides the following technical solution: a method for using an irrigation ditch, comprising the following steps: First, the driving component in the culvert base drives the lifting gate to rise and open, allowing water in the river channel to flow in, and the filter slide on the side of the culvert base away from the lifting gate is used to intercept debris in the river water. The electric push rods on both sides of the inner wall of the installation cover drive the shaking material component to move through rotation and extension, so that the digging plate on the shaking material component can salvage the debris intercepted by the filter slide, so that the river water can flow smoothly from the filter slide into the ditch. As the electric push rod drives the shaking material component to rise, the coordination component at one end of the digging plate drives the cover on the collection box to gradually open, and the electric push rod drives the digging plate on the shaking material component to pour the salvaged debris into the collection box.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The driving component drives the lifting gate to lift and open, allowing the river water to flow into the culvert. The filter skateboard on the other side is used to intercept and salvage garbage and debris in the river water, which can remove suspended matter, silt and other impurities in the water, improve water quality, and ensure the cleanliness of the water body. The cooperation of the electric push rod and the shaking material component drives the digging plates on both sides to salvage the debris intercepted in front of the filter skateboard. Cleaning the filter skateboard can ensure its normal operation, improve the filtration efficiency, and reduce the decline in filtration effect caused by blockage, which can ensure the smooth flow of water. The debris salvaged on the digging plate is tilted and poured into the collection box on one side through the shaking material component. As the electric push rod drives the digging plate into the water again, the cover on the collection box is automatically closed through the coordination component.

[0017] 2. When the limiting pulley slides along the inclined guide groove to the drop groove, the excavation plate will slide from the inclined guide groove to the drop groove under the action of its own weight and vibrate, so that the limiting slider slides along the limiting slide column and squeezes the spring on one side for buffering. The excavation plate shakes while moving toward the collection box, and the debris on the excavation plate is evenly shaken into the collection box on one side, which can reduce the mutual adhesion between the debris and improve the unloading rate of the entire process. The debris can be evenly laid on the lifting plate and evenly distributed in the collection box to avoid accumulation at a certain position in the collection box, resulting in waste of space.

[0018] 3. When the electric push rod drives the digging plate to rise and fall along the limit guide groove 1 and the limit guide groove 2, the limit shaft at one end of the digging plate will drive the limit rod and the storage rod to make the cover gradually open along the collection box, and control the opening and closing of the cover along with the movement of the digging plate. When the digging plate pours down debris, the cover will automatically open to allow the garbage to fall smoothly into the collection box. After the unloading is completed, the cover will automatically close, which can effectively prevent the leakage of odor and keep the working environment clean.

[0019] 4. The water stains carried by the debris flow along the drainage groove opened on the lifting plate and flow into the collection chamber in the collection box for collection. With several rounds of salvaging, the debris on the lifting plate will gradually increase. Under the action of the weight of the debris, the lifting plate will be pushed downward to squeeze the reset spring piece 2, so that the squeezing block enters the collection chamber. The water collected in the collection chamber is discharged from the collection box by squeezing. The concentrated water stains are easy to clean regularly, reducing the trouble of repeated cleaning of water stains scattered everywhere in the box, and improving the convenience of daily maintenance.

[0037] Specifically, when the electric push rod 204 drives the digging plate 205 to rise and fall along the limiting guide groove 1 212 and the limiting guide groove 2 213, the limiting shaft 303 at one end of the digging plate 205 will drive the limiting rod 304 and the storage rod 306 to make the cover plate 302 gradually open along the collection box 301, and when the limiting pulleys 209 on both sides of the digging plate 205 move toward the side of the collection box 301 along the inclined guide groove, the digging plate 205 will push the limiting rod 304 to slide into the storage rod 306 to squeeze the coordination spring piece 309, and the limiting slide grooves 305 on both sides of the limiting rod 304 are limited by the storage slider 307, and the opening and closing of the cover plate 302 is controlled following the movement of the digging plate 205, and the digging plate 205 is moved at the edge through the shaking assembly. The debris will be evenly spread on the lifting plate 310 in the collection box 301, and the water stains on the debris will flow along the drainage groove 311 opened on the lifting plate 310, and flow into the collection chamber 313 in the collection box 301 for collection. With several rounds of salvaging, the debris on the lifting plate 310 will gradually increase, and the weight of the debris will push the lifting plate 310 to move downward to squeeze the reset spring 312, so that the squeeze block 314 enters the collection chamber 313, and the squeezed water of the squeeze block 314 will enter along the water inlet at one end of the drainage tube 315, pushing the ball 319 to move toward the tripod 317 to squeeze the reset spring 320, and drain the water in the collection chamber 313.
