Description

Technical Field

[0001] The present invention relates to the technical field of agricultural water conservation, and particularly relates to a prefabricated and assembled culvert gate and a usage method for irrigation ditches. Background Art

[0002] An irrigation channel is a watercourse that connects an irrigation water source and irrigated land, and conveys and distributes the water diverted from the water source to various parts of the irrigation area. Within an irrigation area, the irrigation channels are divided into five levels: main canal, branch canal, distributary canal, field canal, and hair canal according to the size of the controlled area. In an irrigation area with complex terrain and a large area, multiple levels of channels such as main main canal, sub-main canal, branch canal, and sub-distributary canal can be added. In an irrigation area with a small area, the number of channel levels can be reduced. The longitudinal and cross-sections of the channels should be designed based on data such as the designed irrigation flow rate and the designed irrigation water level.

[0003] A self-maintaining culvert gate structure for a culvert gate water conservancy project disclosed in Chinese Patent CN118668654A has a protective frame sleeved at the bottom end of the first vertical plate, and uses thick filters on both sides for use when the gate baffle is opened, preventing floating objects in the reservoir from clogging the culvert gate, improving the flow efficiency of the reservoir when discharging water through the gate, and driving the second lead screw by the rotation of the second servo motor, so that the linkage sleeve drives the three groups of fine filters away from the ports of the first water discharge port, the second water discharge port, and the third water discharge port, ensuring the flow efficiency of the water discharge port.

[0004] When the above-mentioned prefabricated and assembled culvert gate is in use, the floating objects in the river water are intercepted by the thick filter and the fine filter to ensure the flow efficiency when discharging water through the gate. As time goes by, the sundries intercepted in the river water will accumulate in front of the filter, resulting in most of the area of the filter being blocked, reducing the flow efficiency of the river water and affecting the irrigation effect. Summary of the Invention

[0014] The overall shapes of the first limiting guide groove and the second limiting guide groove are the same. The first guide groove is smaller in size and lower in height than the second guide groove. Both include a rising chute, an inclined chute, and a falling chute, and form a limiting guide groove structure by connecting end to end. Between the connection of the inclined chute and the falling chute, the falling chute is deeper than the inclined chute.

[0015] As a preferred solution of the prefabricated and assembled culvert gate of the present invention, a limiting block is slidably connected in the first limiting guide groove, and a release block is slidably connected in the second limiting guide groove. The surface of the release block is provided with a bevel for the limiting pulley to pass through. Both the limiting block and the release block are slidably connected to one side of the pier. The height of the limiting block is one section lower than that of the release block, reducing the downward pressing amplitude of the release block on the pier.

A receiving cavity is provided in the receiving rod, and a coordination elastic piece is fixedly installed in the receiving cavity.

[0018] As a preferred solution of the prefabricated and assembled culvert gate of the present invention, a lifting plate is slidably connected in the collection box. A drainage groove is provided on the lifting plate. The drainage groove includes a confluence groove horizontally provided on the surface of the lifting plate and a dripping groove vertically penetrating the lifting plate. A second reset elastic piece is connected between the lifting plate and the collection box. A collection cavity is provided in the collection box. The lower surface of the lifting plate is fixedly connected to a pressing block, and the bottom end of the pressing block is slidably connected in the collection cavity.

[0019] As a preferred solution of the prefabricated culvert gate described in the present invention, a drainage cylinder is fixedly installed on one side of the collection box. A conical through hole is formed in the drainage cylinder. The water inlet end of the conical through hole is a conical inclined surface. A three-legged plate is fixedly connected in the conical through hole. A directional rod is fixedly installed on one side of the three-legged plate. The end of the directional rod away from the three-legged plate is connected with a sphere. A return spring is connected between the three-legged plate and the sphere. The return spring pushes the sphere to block the water inlet of the conical through hole.

[0020] To achieve the above object, the present invention provides the following technical solution: A method for using an irrigation ditch, including the following steps:

[0021] First, drive the lifting gate to rise and open through the drive assembly in the culvert gate seat, so that the water in the river flows in. Intercept the sundries in the river water through the filter screen slide plate on the side of the culvert gate seat away from the lifting gate. The electric push rods on both sides of the inner wall of the installation cover drive the material shaking assembly to move through rotation and telescoping, so that the digging plates on the material shaking assembly salvage the sundries intercepted by the filter screen slide plate, so that the river water can smoothly flow through the filter screen slide plate and into the ditch. As the electric push rod drives the material shaking assembly to rise, the cover plate on the collection box is gradually opened by the coordination assembly at one end of the digging plate. The digging plates on the material shaking assembly driven by the electric push rod pour the salvaged sundries into the collection box.

[0022] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0023] 1. Drive the lifting gate to lift and open through the drive assembly, so that the river water flows into the culvert gate. Intercept and salvage the garbage and sundries in the river water through the filter screen slide plate on the other side, which can remove impurities such as suspended solids and sediment in the water, improve the water quality, and ensure the cleanliness of the water body. Through the cooperation of the electric push rod and the material shaking assembly, drive the digging plates on both sides to salvage the sundries intercepted in front of the filter screen slide plate. Cleaning the filter screen slide plate can ensure its normal operation, improve the filtration efficiency, reduce the decline of the filtration effect caused by blockage, and ensure the smooth flow of water. The material shaking assembly tilts and pours the sundries salvaged on the digging plate into the collection box on one side. As the electric push rod drives the digging plate to enter the water again, the cover plate on the collection box is automatically closed by the coordination assembly.

[0024] 2. When it slides along the inclined guide groove to the drop chute through the limit pulley, the excavation board will slide from the inclined guide groove into the drop chute under its own weight and vibrate. This causes the limit slider to slide along the limit slide post and squeeze the spring on one side for buffering. While the excavation board moves towards the collection box, it jitters, evenly shaking the sundries on the excavation board into the collection box on one side. This can reduce the mutual adhesion between sundries, improve the feeding rate of the entire process, evenly lay the sundries on the lifting plate, and evenly distribute the sundries in the collection box, avoiding accumulation at a certain position in the collection box and resulting in wasted space.

[0025] 3. When the electric push rod drives the excavation board to lift along the first limit guide groove and the second limit guide groove, the limit shaft at one end of the excavation board will drive the limit rod and the receiving rod to gradually open the cover plate along the collection box, controlling the opening and closing of the cover plate following the movement of the excavation board. When the excavation board drops sundries, the cover plate will automatically open to allow the garbage to smoothly fall into the collection box. When the feeding is completed, the cover plate will automatically close, which can effectively prevent the leakage of odors and keep the working environment clean.

[0026] 4. The water stains carried by the sundries flow along the drainage grooves opened on the lifting plate and flow into the collection cavity in the collection box for collection. As the sundries are salvaged several times, the sundries on the lifting plate will gradually increase. Under the action of the weight of the sundries, the lifting plate will be pushed downward to squeeze the second reset elastic piece, causing the extrusion block to enter the collection cavity, and discharging the water collected in the collection cavity from the collection box through extrusion. The concentrated water stains are easy to clean regularly, reducing the trouble of repeatedly cleaning the water stains scattered everywhere in the box and improving the convenience of daily maintenance.

Detailed implementation manners

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The present invention will be further described below with reference to the embodiments.

[0041] Embodiment 1

[0042] Referring to Figures 1 - 3 , which is the first embodiment of the present invention, a prefabricated and assembled culvert gate is provided, including a culvert gate base 100. A salvage and cleaning structure 200 is arranged below the culvert gate base 100. The salvage and cleaning structure 200 includes a lifting gate 201 slidably connected in the culvert gate base 100. A driving assembly capable of driving the lifting gate 201 to lift is arranged in the culvert gate base 100. A filter screen slide plate 202 is fixedly installed on one side of the culvert gate base 100 away from the lifting gate 201. Two filter screen cloths are arranged on the filter screen slide plate 202, and a support plate for fixing the filter screen cloths is in the middle. Installation covers 203 are fixedly installed on both sides of the culvert gate base 100. A pushing assembly is rotatably connected to the inner wall of the installation cover 203. The telescopic end of the pushing assembly is connected to a material shaking assembly. An excavation plate 205 is slidably connected to the material shaking assembly. The excavation plate 205 is slidably connected between the lifting gate 201 and the filter screen slide plate 202;

[0043] One end of the excavation plate 205 away from the lifting gate 201 and the filter screen slide plate 202 is connected to a coordination assembly. A collection and storage structure 300 is arranged on one side of the salvage and cleaning structure 200. The collection and storage structure 300 includes a collection box 301 arranged below the installation cover 203. One end of the coordination assembly is connected to a cover plate 302. The cover plate 302 is rotatably connected to the collection box 301.

[0044] Specifically, the driving assembly in the culvert gate base 100 drives the lifting gate 201 to rise and open, so that the water in the river flows in. The filter screen slide plate 202 on the side of the culvert gate base 100 away from the lifting gate 201 intercepts the sundries in the river water. The electric push rods 204 on both sides of the inner wall of the installation cover 203 drive the material shaking assembly to move through rotation and telescoping, so that the excavation plate 205 on the material shaking assembly salvages the sundries intercepted by the filter screen slide plate 202, enabling the river water to smoothly flow through the filter screen slide plate 202 and into the ditch. As the electric push rod 204 drives the material shaking assembly to rise, the cover plate 302 on the collection box 301 is gradually opened by the coordination assembly at one end of the excavation plate 205. The excavation plate 205 on the material shaking assembly driven by the electric push rod 204 dumps the salvaged sundries into the collection box 301.

[0045] The lifting gate 201 is driven by a driving component to lift and open, allowing river water to flow into the culvert. The filter screen slide plate 202 on the other side intercepts and salvages garbage and sundries in the river water, which can remove impurities such as suspended solids and sediment in the water, improve water quality, and ensure the cleanliness of the water body. The electric push rod 204 and the material shaking component cooperate to drive the excavation plates 205 on both sides to salvage the sundries intercepted in front of the filter screen slide plate 202. Cleaning the filter screen slide plate 202 can ensure its normal operation, improve the filtration efficiency, reduce the decline of the filtration effect caused by blockage, and ensure the smooth flow of water. The sundries salvaged on the excavation plates 205 are tilted and poured into the collection box 301 on one side by the material shaking component. When the electric push rod 204 drives the excavation plates 205 to enter the water again, the cover plate 302 on the collection box 301 is automatically closed by the coordination component.

[0046] Embodiment 2

[0047] Refer to Figures 1 - 7 , which is the second embodiment of the present invention. A prefabricated and assembled culvert is provided.

One end of the lifting screw 101 away from the lifting gate 201 is provided with a motor 102, and a limit frame 103 is fixedly connected below the motor 102;

[0048] A cleaning brush plate 206 is slidably installed on the side of the excavation plate 205 close to the filter screen slide plate 202. The cleaning brush plate 206 includes a brush plate, a mounting slider, and a handle. The cleaning brush plate 206 is slidably connected to one side of the filter screen slide plate 202. The pushing component includes an electric push rod 204. The electric push rod 204 is rotatably connected to the inner wall of the mounting cover 203. The output end of the electric push rod 204 is rotatably connected to a limit slider 207. Limit sliding columns 208 are fixedly installed on both sides of the excavation plate 205. Inclined shoveling surfaces are provided at the corresponding ends of the two excavation plates. A filter screen is in the middle of the excavation plate 205. The limit slider 207 is slidably connected to the limit sliding column 208. Springs are provided on both sides of the limit slider 207. The springs are sleeved on the limit sliding column 208. Inclined shoveling surfaces are provided at the corresponding ends of the two excavation plates 205. A filter screen is in the middle of the excavation plate 205. The cleaning brush plate 206 can brush off the impurities attached to the surface of the filter screen slide plate 202. The cleaning brush plate 206 on one side of the excavation plate 205 can be replaced according to the usage situation. Springs sleeved on the limit sliding columns 208 are provided on both sides of the limit slider 207, which plays a role in vibration buffering for the excavation plate 205.

[0049] The vibrating material component includes limiting pulleys 209 arranged on both sides of the excavation plate 205. An adjusting elastic sheet 210 is arranged between the limiting pulley 209 and the excavation plate 205. Pier blocks 211 are arranged on both sides of the excavation plate 205, and reinforcing ribs are arranged on the outer side of the pier blocks 211 to reinforce and support them. The limiting pulley 209 is slidably connected to the excavation plate 205 in the left-right direction, and the limiting pulleys 209 on both sides of the excavation plate 205 are respectively slidably connected to the pier blocks 211 on both sides.

[0050] Limiting guide grooves one and two are provided on the pier block. The limiting guide grooves one and two are respectively formed by connecting the heads and tails of three different tracks to form a triangular guide groove structure.

[0051] The overall shapes of the limiting guide groove one and the limiting guide groove two are the same, and the height of the limiting guide groove one 212 is lower than the height of the limiting guide groove two 213. The limiting guide groove one 212 and the limiting guide groove two 213 both include a rising chute 2131, an inclined chute 2132, and a falling chute 2133, which are connected end to end to form a limiting guide groove structure. Between the connection points of the inclined chute 2132 and the falling chute 2133, the falling chute 2133 is deeper than the inclined chute 2132. Between the connection points of the falling chute 2133 and the rising chute 2131, the rising chute 2131 is deeper than the falling chute 2133, so that each chute connection point has the function of limiting and guiding the limiting pulley. Drop grooves are provided on both the limiting guide groove one and the limiting guide groove two. The drop grooves are spaced apart on the inclined chute. The total stroke of the limiting guide groove two 213 is larger than that of the limiting guide groove one 212. Drop grooves 214 are spaced apart on the inclined guide groove, which can enable the limiting pulley 209 to slide along the drop.

[0052] A limiting block 215 is slidably connected in the limiting guide groove one 212, and a release block 216 is slidably connected in the limiting guide groove two 213. The surface of the release block 216 is provided with an inclined edge for the limiting pulley 209 to pass through. Both the limiting block 215 and the release block 216 are slidably connected to one side of the pier block 211. The height of the limiting block 215 is one section lower than that of the release block 216, reducing the downward pressing amplitude of the release block 216 on the pier block 211. A coordination plate 217 is fixedly connected between the limiting block 215 and the release block 216. The coordination plate 217 is slidably connected in the pier block 211. A first reset elastic sheet 218 is fixedly installed on the lower surface of the limiting slider 207. The shape of the limiting block 215 is square, and the shape of the release block 216 is trapezoidal, which respectively move up and down and slide in the limiting guide groove one 212 and the limiting guide groove two 213. The limiting blocks 215 and the release blocks 216 of the two tracks are coordinately controlled by the coordination plate 217.

[0053] Specifically, the telescopic end of the electric push rod 204 drives the excavation plate 205 to slide between the two side piers 211. The limit pulleys 209 on both sides of the excavation plate 205 slide in the first limit guide groove 212 and the second limit guide groove 213 respectively to salvage the sundries intercepted on one side of the filter screen slide plate 202. When the right limit pulley 209 slides down along the ascending chute 2131 to the inclined chute 2132, it will be blocked by the limit block 215 in the first limit guide groove 212, causing the left limit pulley 209 to continue to slide up along the lifting guide groove and then fall into the inclined guide groove, making the excavation plate 205 tilt. When the left limit pulley 209 passes along the hypotenuse of the release block 216, the limit pulley 209 will push the drop chute 214 to retract into the pier 211 and squeeze the first reset elastic sheet 218, and drive the limit block 215 in the first limit guide groove 212 to retract simultaneously through the coordination plate 217, enabling the two limit pulleys 209 to continue sliding along the inclined chute 2132. When the limit pulley 209 slides along the inclined chute 2132 to the drop chute 214, the excavation plate 205 will slide from the inclined chute 2132 into the drop chute 214 under its own weight and vibrate, causing the limit slider 207 to slide along the limit slide post 208 and squeeze the spring on one side for buffering. With the continuous tilting, rising and jittering of the excavation plate 205, the sundries on the excavation plate 205 are evenly scattered into the collection box 301 on one side for collection. The electric push rod 204 will drive the excavation plate 205 to descend from both sides of the filter screen slide plate 202 along the falling chute 2133 back to the bottom of the filter screen slide plate 202 without driving the sundries intercepted in front of the filter screen slide plate 202, improving the cleaning quality of the filter screen slide plate 202.

A guiding rod 318 is fixedly installed on one side of the three-legged plate 317. A sphere 319 is connected to the end of the guiding rod 318 away from the three-legged plate 317. A reset spring 320 is connected between the three-legged plate 317 and the sphere 319. The reset spring 320 pushes the sphere 319 to block the water inlet of the tapered through hole 316. Through holes are formed around the three-legged plate 317 to allow water to pass through. The reset spring 320 is sleeved on the guiding rod 318. The guiding rod 318 plays a role in guiding the sphere 319. The reset spring 320 will push the sphere 319 to block the water outlet.

[0059] Specifically, when the electric push rod 204 drives the excavation plate 205 to lift along the first limiting guide groove 212 and the second limiting guide groove 213, the limiting shaft 303 at one end of the excavation plate 205 will drive the limiting rod 304 and the storage rod 306 to gradually open the cover plate 302 along the collection box 301. When the limiting pulleys 209 on both sides of the excavation plate 205 move along the inclined guide groove towards the side of the collection box 301, the excavation plate 205 will push the limiting rod 304 to slide into the storage rod 306 and squeeze the coordination elastic sheet 309. The limiting slide block 307 limits the limiting slide grooves 305 on both sides of the limiting rod 304, and controls the opening and closing of the cover plate 302 following the movement of the excavation plate 205. The vibration component makes the excavation plate 205 vibrate while moving to scatter the sundries into the collection box 301. The sundries will be evenly laid on the lifting plate 310 in the collection box 301. The water stains carried on the sundries will flow along the drainage groove 311 opened on the lifting plate 310 and flow into the collection cavity 313 in the collection box 301 for collection. As the salvage is carried out in several rounds, the sundries on the lifting plate 310 will gradually increase. Under the action of the weight of the sundries, the lifting plate 310 will be pushed downward to squeeze the second reset elastic sheet 312, so that the extrusion block 314 enters the collection cavity 313. The water is pushed into the collection cavity 313 through the water inlet at one end of the drainage cylinder 315 by the extrusion of the extrusion block 314, and the sphere 319 is pushed towards the tripod plate 317 to squeeze the reset spring 320, discharging the water in the collection cavity 313.

[0060] Embodiment 4

[0061] Referring to Figures 1 - 3 , for the fourth embodiment of the present invention, a method for using a prefabricated and assembled culvert gate in an irrigation ditch is provided, including the following steps:

[0062] First, the driving component in the culvert gate base 100 drives the lifting gate 201 to rise and open, allowing the water in the river to flow in. The filter plate 202 on the side of the culvert gate base 100 away from the lifting gate 201 intercepts the sundries in the river water. The electric push rods 204 on both sides of the inner wall of the installation cover 203 drive the vibration component to move through rotation and telescoping, so that the excavation plate 205 on the vibration component salvages the sundries intercepted by the filter plate 202, enabling the river water to smoothly flow through the filter plate 202 and into the ditch. As the electric push rod 204 drives the vibration component to rise, the cover plate 302 on the collection box 301 is gradually opened by the coordination component at one end of the excavation plate 205. The electric push rod 204 drives the excavation plate 205 on the vibration component to pour the salvaged sundries into the collection box 301.
