Description

Technical Field

[0001] The invention belongs to the technical field of comprehensive water erosion prevention and control, and specifically relates to a device and method for comprehensive farmland water erosion prevention and control. Background Art

[0002] Soil erosion refers to the process of destruction, displacement and deposition of ground materials under the action of water. The factor that has the greatest impact on soil erosion is rainfall. The most serious erosion only occurs when there is moderate rainfall, the vegetation is severely damaged, and the forest is cut down under high-intensity rainfall conditions. At the same time, the problem lies not only in the "total amount" of rainfall, but also in the "rain type". The heavy rainstorms in tropical regions have more serious destructive effects than the milder rainfall in temperate regions.

[0003] Soil erosion leads to serious consequences: First, the loss of fertile topsoil destroys land resources, reduces land productivity, and affects food and ecological security; second, the silt that migrates with the erosion process blocks rivers, lakes, and aggravates drought and flood disasters; the migrated pollutants cause eutrophication of rivers, lakes, and reservoirs, which has a serious impact on the ecological environment and social economy of downstream areas; third, erosion and transportation causes changes in the content and composition of soil carbon, nitrogen, and phosphorus, which in turn affects the global circulation of biogenic factors and even becomes an important driving factor of global climate change.

[0004] Farmland erosion control devices refer to equipment or structures used to reduce or prevent soil erosion caused by water erosion in farmland. Such devices usually combine agricultural technology, water conservancy projects and ecological protection measures to achieve the purpose of comprehensive management.

[0005] Common farmland water erosion prevention and control devices include: water retaining dams (intercepting ditches), which slow down the flow of water and reduce erosion by setting up small water retaining dams or ditches on the surface; reservoirs, which collect rainwater or surface runoff for irrigation or other purposes, reducing the amount of water that directly washes the ground; underground drainage systems, which discharge excess groundwater through underground pipes or ditches, reduce soil moisture content, and reduce erosion caused by water accumulation; slope protection, which can effectively reduce soil erosion caused by rainwater washout in hilly areas or farmland with undulating terrain, reduce direct rainwater impact on the ground, and protect farmland from water erosion.

[0006] At present, in hilly areas or farmlands with undulating terrain, in order to prevent and control farmland water erosion, slope protection is often used to protect farmland from water erosion, and ditches are dug under the slope protection. However, in hilly areas or places with undulating terrain, stones are easily dropped with the erosion of rainwater. The current slope protection cannot handle the stones. In fact, due to their hard texture and smooth slope, the rolling speed of the stones will be accelerated. The stones will not only cause blockage of the ditches, affecting the drainage effect of the ditches, but also easily cause damage to the ditches, affecting the drainage effect of the ditches. In addition, it is time-consuming and laborious to clean up, which is not convenient for long-term use.

[0007] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0012] In one or more embodiments of the present invention, the impact buffer storage bin is arranged to penetrate the barrier frame, which facilitates the installation of the impact buffer storage bin, ensures the installation space of the impact buffer storage bin, and reserves space for the sliding of the impact buffer compression rod; The impact buffer storage bin is fixedly installed with the blocking frame, and an impact buffer compression rod is slidably installed in the impact buffer storage bin, which can move synchronously with the movement of the impact buffer folding plate, so that the elastic force of the impact buffer compression spring can be applied to the impact buffer folding plate, and the impact buffer compression rod is fixedly installed with the impact buffer folding plate; An impact buffer compression spring is installed between the impact buffer compression rod and the impact buffer accommodating chamber. When the impact buffer folding plate slides, the impact buffer compression spring can be compressed through the displacement of the impact buffer compression rod, so that the impact buffer compression spring can buffer the sliding of the impact buffer folding plate, and further buffer the sliding of the impact buffer guide plate.

[0015] In one or more embodiments of the present invention, a pulling buffer return spring is installed between the pulling buffer reel and the pulling buffer shaft seat, so that the pulling buffer reel can be better wound up and the pulling buffer return spring can be better buffered when the pulling buffer reel rotates; A pulling buffer reel is installed between the pulling buffer reel and the pulling buffer follower bin, connecting the pulling buffer reel and the pulling buffer follower bin. When the pulling buffer follower bin is pulled by the pulling buffer straight rope, the pulling buffer reel is rotated by pulling the pulling buffer reel rope, and buffering is performed by the pulling buffer return spring.

The pulling buffer protection bin is fixedly installed on the concrete slope.

[0016] In one or more embodiments of the present invention, the efficiency enhancement mechanism includes an efficiency enhancement sink, which can collect rainwater, reduce the probability of rainwater directly washing farmland, and make rainwater flow into the concrete ditch better. The efficiency enhancement sink is set through the concrete slope; The efficiency-enhancing protection net is fixedly installed in the efficiency-enhancing sinking bin, which can reduce the possibility of stones entering the efficiency-enhancing sinking bin, reduce the probability of stones entering the concrete ditch, and make the stones better guided by the impact buffer guide plate, so that the stones enter the efficiency-enhancing cleaning bin, which is convenient for users to clean; An efficiency-enhancing water flow pipe is installed between the efficiency-enhancing sinking bin and the concrete ditch, connecting the efficiency-enhancing sinking bin and the concrete ditch so that the water in the efficiency-enhancing sinking bin can better enter the concrete ditch.

[0017] In one or more embodiments of the present invention, an efficiency-enhancing cleaning bin is fixedly installed on the lower side of the concrete ditch, which facilitates the collection of stones and the cleaning of users; A pair of efficiency-enhancing stone pipes are installed between the efficiency-enhancing cleaning bin and the concrete slope, so that the stones guided by the impact buffer guide plate can enter the efficiency-enhancing stone pipes, so that the stones can enter the efficiency-enhancing cleaning bin better. The efficiency-enhancing stone pipes penetrate the concrete slope and the efficiency-enhancing cleaning bin; A number of uniformly distributed efficiency-enhancing guide plates are fixedly installed on the concrete slope, which can guide stones, reduce the probability of stones directly colliding with the efficiency-enhancing protection net, and improve the protection of the efficiency-enhancing protection net; An efficiency-enhancing guide frame is fixedly installed in the efficiency-enhancing cleaning bin, so that the stones in the efficiency-enhancing cleaning bin are guided, making it easier for the stones to fall at the exit of the efficiency-enhancing cleaning bin, thereby facilitating cleaning for users.

[0018] A method for comprehensive prevention and control of farmland water erosion comprises the following steps: S1. When the stones are rolled down on the concrete slope due to rain erosion, they will first contact the efficiency-enhancing guide plate, so that the stones will not contact the efficiency-enhancing protection net during the rolling process, which can protect the efficiency-enhancing protection net and reduce the probability of stones falling into the efficiency-enhancing sinking bin; S2. After being guided by the efficiency enhancement guide plate, the smaller stone contacts the impact buffer guide plate. After being hit by the stone, the impact buffer guide plate will slide and compress the impact buffer compression spring, so that the impact buffer compression spring can buffer the impact buffer guide plate, which not only reduces the probability of the stone flying, but also protects the impact buffer guide plate; S3. After being guided by the efficiency-enhancing guide plate, the larger stones are not only buffered by the impact buffer guide plate, but also can cause the blocking frame to rotate through the impact, so that the blocking frame pulls the pulling buffer follower plate, and the pulling buffer follower plate squeezes the pulling buffer spring, so that the pulling buffer spring buffers the blocking frame; S4. After being buffered, the stones will be guided by the impact buffer guide plate, and fall into the efficiency-enhancing cleaning bin through the efficiency-enhancing stone pipe, and guided by the efficiency-enhancing guide frame, which is convenient for users to clean; S5. Rainwater flows downward on the concrete slope. A large amount of rainwater will enter the efficiency-enhancing sinking bin and flow into the concrete ditch through the efficiency-enhancing water flow pipe. A small amount of rainwater will be guided by the impact buffer guide plate and flow into the concrete ditch through the impact buffer installation net and the barrier impact net, thereby achieving the effect of protecting farmland.

[0019] Compared with the prior art, the device and method for comprehensive prevention and control of farmland water erosion of the present invention enable slope protection to process stones through the setting of corresponding mechanisms, which not only reduces the probability of ditch blockage and reduces the impact on the ditch drainage effect, but also reduces the damage to the ditch and reduces the impact on the ditch drainage effect.

[0029] Among them, a blocking bearing 204 is installed between the blocking support rod 203 and the blocking frame 201, which improves the smoothness of the rotation of the blocking frame 201, increases the friction between the blocking frame 201 and the blocking support rod 203, and enables the blocking frame 201 to rotate smoothly after being subjected to force.

[0030] In addition, the blocking support rod 203 is fixedly installed with the concrete slope 1, which improves the stability of the blocking support rod 203, ensures the balance of the blocking support rod 203, and enables the blocking support rod 203 to better support the rotation of the blocking frame 201.

[0031] like Figures 1 to 5 As shown, a collision buffer mechanism 3 is provided on the side of the blocking collision net 202 away from the concrete ditch 101, which is used to protect the blocking collision net 202. The collision buffer mechanism 3 includes an collision buffer guide plate 301, which can not only guide the stone after contacting the stone, but also buffer the stone by sliding after being hit by the stone, so as to reduce the probability of the stone being bounced off and make it easier for the stone to be guided by the collision buffer guide plate 301.

At the same time, the impact buffer guide plate 301 can move synchronously with the impact buffer folding plate 302.

[0033] In addition, an impact buffer mounting net 303 is fixedly installed between the impact buffer fold plate 302 and the impact buffer guide plate 301, which not only connects the impact buffer guide plate 301 and the impact buffer fold plate 302, thereby ensuring the connectivity between the impact buffer guide plate 301 and the impact buffer fold plate 302, but also enables the impact buffer guide plate 301 to move synchronously with the impact buffer fold plate 302.

[0034] In addition, a pair of impact buffer accommodating chambers 304 are provided on the side of the impact buffer folding plate 302 close to the blocking frame 201, which facilitates the sliding of the impact buffer compression rod 305, makes the balance of the impact buffer compression rod 305 more ideal, and provides corresponding space for the installation of the impact buffer compression spring 306.

[0035] like Figures 1 to 4 As shown, the impact buffer accommodating chamber 304 is arranged to penetrate the blocking frame 201, which facilitates the installation of the impact buffer accommodating chamber 304, ensures the installation space of the impact buffer accommodating chamber 304, and reserves space for the sliding of the impact buffer compression rod 305.

[0036] In addition, the impact buffer accommodating chamber 304 is fixedly installed with the blocking frame 201, and an impact buffer compression rod 305 is slidably installed in the impact buffer accommodating chamber 304, which can move synchronously with the movement of the impact buffer folding plate 302, so that the elastic force of the impact buffer compression spring 306 can be applied to the impact buffer folding plate 302, and the impact buffer compression rod 305 is fixedly installed with the impact buffer folding plate 302.

[0037] In addition, an impact buffer compression spring 306 is installed between the impact buffer compression rod 305 and the impact buffer accommodating chamber 304. When the impact buffer folding plate 302 slides, the impact buffer compression spring 306 can be compressed through the displacement of the impact buffer compression rod 305, so that the impact buffer compression spring 306 can buffer the sliding of the impact buffer folding plate 302, and then buffer the sliding of the impact buffer guide plate 301.

[0038] like Figures 1 to 5 As shown, a plurality of pulling and buffering mechanisms 4 are installed between the blocking frame 201 and the concrete slope 1 to enhance the protection of the blocking and impacting net 202. The pulling and buffering mechanisms 4 include a pulling and buffering follower bin 401, which facilitates the sliding of the pulling and buffering follower plate 402 and provides corresponding space for the sliding of the pulling and buffering follower plate 402, thereby ensuring the balance of the pulling and buffering follower plate 402.

[0039] Among them, a pulling buffer follower plate 402 is slidably installed in the pulling buffer follower bin 401, which can slide by pulling the pulling buffer straight rope 406, and at the same time apply corresponding force to compress the pulling buffer spring 403, so that the pulling buffer spring 403 can buffer the pulling buffer follower plate 402.

[0040] In addition, a pulling buffer spring 403 is installed between the pulling buffer follower plate 402 and the pulling buffer follower chamber 401, which can squeeze the pulling buffer follower plate 402 so that the pulling buffer follower plate 402 can be buffered accordingly.

[0041] In addition, a pulling buffer support rod 404 is fixedly installed on the blocking frame 201, which facilitates the installation of the pulling buffer swivel 405 and provides corresponding support for the fixation of the pulling buffer swivel 405, so that the pulling buffer swivel 405 can rotate on the pulling buffer support rod 404.

[0042] Among them, a torsion groove matching the pulling buffer support rod 404 is bored on the blocking frame 201, which facilitates the rotation of the pulling buffer swivel 405 and provides corresponding space for the rotation of the pulling buffer swivel 405, so that the pulling buffer swivel 405 can rotate better.

[0043] like Figures 1 to 6 As shown, a plurality of pull buffer swivels 405 are rotatably mounted on the pull buffer support rod 404, which can connect the pull buffer support rod 404 and the pull buffer follower plate 402, so that the blocking frame 201 can better move relative to the pull buffer support rod 404 when rotating.

[0044] In addition, a pulling buffer straight rope 406 is installed between the pulling buffer swivel 405 and the pulling buffer follower plate 402, connecting the pulling buffer follower plate 402 and the pulling buffer swivel 405, so that the rotation of the blocking frame 201 can pull the pulling buffer straight rope 406, allowing the pulling buffer follower plate 402 to slide synchronously.

[0045] In addition, a pulling and buffering shaft seat 407 is fixedly installed on the concrete slope body 1, which can support the pulling and buffering reel 408, provide corresponding space for the rotation of the pulling and buffering reel 408, and assist in the balance of the pulling and buffering reel 408.

[0046] Among them, a pulling buffer reel 408 is rotatably installed on the pulling buffer shaft seat 407, and the pulling buffer rope 410 can be wound around the pulling buffer reel 408, which facilitates the winding of the pulling buffer rope 410, so that the stretching of the pulling buffer rope 410 also synchronously buffers the rotation of the blocking frame 201.

[0047] like Figures 1 to 7As shown, a pulling buffer return spring 409 is installed between the pulling buffer reel 408 and the pulling buffer shaft seat 407, so that the pulling buffer winding rope 410 can be better wound up and the pulling buffer return spring 409 can better buffer the pulling buffer reel 408 when it rotates.

[0048] Among them, a pulling buffer rope 410 is installed between the pulling buffer reel 408 and the pulling buffer follower bin 401, connecting the pulling buffer reel 408 and the pulling buffer follower bin 401. When the pulling buffer follower bin 401 is pulled by the pulling buffer straight rope 406, the pulling buffer reel 408 is rotated by the pulling of the pulling buffer rope 410, and buffering is performed by the pulling buffer return spring 409.

[0049] In addition, a pulling buffer protection bin 411 is provided on the outside of the pulling buffer shaft seat 407, which can protect the pulling buffer reel 408, reduce the possibility of the pulling buffer reel 408 being hit by stones, and reduce the probability of damage to the pulling buffer reel 408. The pulling buffer protection bin 411 is fixedly installed on the concrete slope 1.

[0050] like Figures 1 to 7 As shown, an efficiency-enhancing mechanism 5 is fixedly installed on the lower side of the concrete slope 1 for enhancing the use effect of the rotating blocking mechanism 2. The efficiency-enhancing mechanism 5 includes an efficiency-enhancing sinking bin 501, which can collect rainwater, thereby reducing the probability of rainwater directly washing the farmland and allowing rainwater to flow better into the concrete ditch 101. The efficiency-enhancing sinking bin 501 is arranged throughout the concrete slope 1.

[0051] Among them, an efficiency-enhancing protective net 502 is fixedly installed in the efficiency-enhancing sinking bin 501, which can reduce the possibility of stones entering the efficiency-enhancing sinking bin 501 and the probability of stones entering the concrete ditch 101, so that the stones can be better guided by the impact buffer guide plate 301, so that the stones can enter the efficiency-enhancing cleaning bin 504, making it convenient for users to clean them.

[0052] In addition, an efficiency-enhancing water flow pipe 503 is installed between the efficiency-enhancing sinking bin 501 and the concrete ditch 101, connecting the efficiency-enhancing sinking bin 501 and the concrete ditch 101, so that the water in the efficiency-enhancing sinking bin 501 can better enter the concrete ditch 101, and the efficiency-enhancing water flow pipe 503 runs through the efficiency-enhancing sinking bin 501 and the concrete ditch 101.

[0053] like Figures 1 to 6 As shown, an efficiency-enhancing cleaning bin 504 is fixedly installed on the lower side of the concrete ditch 101, which facilitates the collection of stones and the cleaning of the user.

[0054] Among them, a pair of efficient gravel pipes 505 are installed between the efficient cleaning bin 504 and the concrete slope 1, so that the gravel guided by the impact buffer guide plate 301 can enter the efficient gravel pipes 505, so that the gravel can better enter the efficient cleaning bin 504, and the efficient gravel pipes 505 are set through the concrete slope 1 and the efficient cleaning bin 504.

[0055] In addition, a number of uniformly distributed efficiency-enhancing guide plates 506 are fixedly installed on the concrete slope 1 to guide stones, thereby reducing the probability of stones directly colliding with the efficiency-enhancing protection net 502 and improving the protection of the efficiency-enhancing protection net 502.

[0056] In addition, an efficiency-enhancing guide frame 507 is fixedly installed in the efficiency-enhancing cleaning bin 504 to guide the stones in the efficiency-enhancing cleaning bin 504 so that the stones can fall more easily at the exit of the efficiency-enhancing cleaning bin 504, thereby facilitating cleaning by the user.

[0057] A method for comprehensive prevention and control of farmland water erosion comprises the following steps: S1. When the stones are washed by rain and roll down on the surface of the concrete slope 1, they will first contact the efficiency-enhancing guide plate 506, so that the stones will not contact the efficiency-enhancing protection net 502 during the rolling process, and the efficiency-enhancing protection net 502 can be protected, reducing the probability of the stones falling into the efficiency-enhancing sinking bin 501.

[0058] S2. After being guided by the efficiency-enhancing guide plate 506, the smaller stones come into contact with the impact buffer guide plate 301. After being hit by the stones, the impact buffer guide plate 301 will slide and compress the impact buffer compression spring 306, so that the impact buffer compression spring 306 can buffer the impact buffer guide plate 301, which not only reduces the probability of the stones flying, but also protects the impact buffer guide plate 301.

[0059] S3. After being guided by the efficiency-enhancing guide plate 506, the larger stones are not only buffered by the impact buffer guide plate 301, but also can cause the blocking frame 201 to rotate through the impact, so that the blocking frame 201 pulls the pulling buffer follower plate 402, and the pulling buffer spring 403 is squeezed by the pulling buffer follower plate 402, so that the pulling buffer spring 403 buffers the blocking frame 201.

[0060] S4. After being buffered, the stones are guided by the impact buffer guide plate 301, and fall into the efficiency-enhancing cleaning bin 504 through the efficiency-enhancing stone pipe 505, and are guided by the efficiency-enhancing guide frame 507, which facilitates cleaning by the user.

[0061] S5. Rainwater flows downward on the concrete slope 1.
