Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering equipment, and particularly relates to a self-cleaning device for debris in a water channel for farmland water conservancy projects. Background Technique

[0002] As an important means for humans to rationally utilize water resources, water conservancy projects achieve the effective control and allocation of surface water and groundwater in nature by building various hydraulic structures such as dams, dikes, spillways, sluice gates, channels, aqueducts, etc., to achieve the goal of eliminating disasters and bringing benefits, and provide an indispensable water resource guarantee for human production and life. In the water conservancy project system, the farmland water channel, as a key water conservancy facility, is an artificial diversion channel, divided into main channels and branch channels, mostly built with stone masonry or cement. Its main function is to accurately introduce water flow into farmland to meet the agricultural irrigation needs. However, during the actual operation process, due to the scouring and carrying of water flow, a large amount of debris such as weeds, tree trunks, fallen leaves, and plastic bags inevitably enters the water channel. Over time, these debris will gradually accumulate in the water channel, resulting in a continuous reduction in the cross-sectional area of the water channel. The reduction of the cross-sectional area directly causes the water flow in the water channel to decrease, and in severe cases, it may even cause blockage, greatly reducing the smoothness of the water channel, making it difficult to normally perform the irrigation and water conveyance function, and thus affecting the growth of crops and the agricultural production efficiency. Currently, for the cleaning of debris in the water channel, mostly manual tools are used. This traditional cleaning method has a large labor intensity, takes a long time, and has extremely low cleaning efficiency.

[0003] Therefore, the present invention provides a self-cleaning device for debris in a water channel for farmland water conservancy projects to solve the above problems. Summary of the Invention

A tension spring is installed between the control frame and the pushing control bin.

[0007] Preferably, guiding frames are slidably connected up and down on both sides of the grid frame. The guiding frames are slidably connected up and down on the U-shaped support frame. The guiding shafts are fixedly connected to one side of the guiding frames close to the guiding grooves.

[0008] Preferably, the horizontal driving device includes sliding plates fixedly connected to the two inner side walls of the U-shaped support frame. Sliding grooves are provided in the sliding plates. Slide rails that are slidably connected to the sliding grooves are fixedly connected to both sides of the cleaning plate.

As the sundries increase, the grille rods are blocked by the sundries, and the water flow inside the channel cannot pass through the grille rods normally. At this time, the water flow inside the channel provides a large pressure to push the grille rods and the grille frame to move on the fixing plate. Under the action of the guide grooves and the guide shafts, the grille frame is pushed upward, and the fallen leaves, weeds, plastic bags, etc. separated on one side of the grille rods are hung on the cleaning teeth and move upward following the grille frame, thereby realizing the operation of cleaning sundries; in this way, it solves the problem that a large amount of sundries such as weeds, tree trunks, fallen leaves, and plastic bags inevitably enter the water channel. With the accumulation of time, these sundries will gradually accumulate inside the water channel, resulting in a continuous reduction in the cross-sectional area of the water channel passing through. This causes a decrease in the water flow of the water channel and even leads to blockage problems. By adding a guide frame, a compression bolt, an adjusting threaded shaft, a connecting push block and a shielding guide, the position of the grille frame can be quickly adjusted according to the water level height; By adding a storage groove, sundries can be collected, and regular processing can greatly save manpower; By adding a cross frame, a scraper and an abutting spring, the cleaning plate can be cleaned.

[0015] The present invention is easy to use, can adapt to various environments, and effectively improves the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Referring to the appended Figure 1-12 description, a self-cleaning device for debris in a canal for farmland water conservancy projects includes: A channel 1, which is arranged in a concave shape; A blocking structure, which is arranged inside the channel 1 and includes fixing plates 2 fixedly installed on the two inner sidewalls of the channel 1. A U-shaped support frame 3 with an open side is horizontally slidably connected between the two fixing plates 2. Horizontal grooves are formed on both fixing plates 2. Horizontal sliding channels slidably connected to the horizontal grooves are fixedly connected to both sides of the U-shaped support frame 3 to control the sliding of the U-shaped support frame 3 on the fixing plates 2. A grille frame 4 is vertically slidably connected inside the U-shaped support frame 3. A plurality of vertically arranged grille rods 5 are fixedly connected to the grille frame 4. A plurality of cleaning hanging teeth 6 are longitudinally arranged on the grille rods 5; A cleaning plate 45, which is horizontally slidably connected to the open side of the U-shaped support frame 3. The cleaning plate 45 is pushed to slide on the U-shaped support frame 3 by a horizontal driving device. A plurality of cleaning teeth 7 cooperating with the grille rods 5 are fixedly connected to one end of the cleaning plate 45 close to the grille rods 5. After the cleaning plate 45 moves to the extreme position in the direction close to the grille rods 5, the cleaning teeth 7 are inserted between two adjacent grille rods 5; The cleaning control structure includes a barrier pushing plate 8 fixedly connected to the bottom of the grille frame 4. A plurality of through holes 9 are arranged at intervals on the barrier pushing plate 8. A shielding plate 10 is slidably connected inside the barrier pushing plate 8. A plurality of communication holes 11 communicating with the through holes 9 are arranged on the shielding plate 10. When the through holes 9 and the communication holes 11 are communicated, water can pass through the through holes 9 and the communication holes 11 to pass through the barrier pushing plate 8; the shielding plate 10 is controlled to slide inside the barrier pushing plate 8 by a pushing structure; The cleaning guiding structure is used to control the sliding of the grille frame 4 on the U-shaped support frame 3, and includes a plurality of guiding grooves 12 obliquely arranged upward on the inner side of the fixing plate 2. The plurality of guiding grooves 12 are arranged in parallel. Guide shafts 13 matching with the guiding grooves 12 are arranged on both sides of the grille frame 4. A cleaning spring 14 is connected between the U-shaped support frame 3 and the fixing plate 2. In the initial state, the grille frame 4 is pulled under the action of the cleaning spring 14, so that the guide shafts 13 are located at the bottommost end of the guiding grooves 12.

[0025] The pushing structure includes a communication guiding block 15 arranged on an inner side wall of the U-shaped support frame 3, and a shielding guiding block 16 is arranged on the other inner side wall of the U-shaped support frame 3. The height of the communication guiding block 15 is higher than that of the shielding guiding block 16. The sides of the communication guiding block 15 and the shielding guiding block 16 close to each other are both set to be arc-shaped; One end of the shielding plate 10 close to the communication guiding block 15 is fixedly connected with a communication pushing block 17 matching with the communication guiding block 15. An inclined angle is arranged at one end of the communication pushing block 17 close to the communication guiding block 15; the other end of the shielding plate 10 is fixedly connected with a pushing control bin 18. A control frame 19 is slidably connected inside the pushing control bin 18. A circular pushing block 20 is movably connected inside the control frame 19. A receiving groove 21 matching with the circular pushing block 20 is arranged at the top of the pushing control bin 18. A tension spring 22 is installed between the control frame 19 and the pushing control bin 18.

[0026] In the initial state, the tension spring 22 pulls the control frame 19 to slide downward to the limit position, and the side of the circular pushing block 20 away from the shielding guiding block 16 contacts the pushing control bin 18; When the grille frame 4 slides upward until the arc surface of the circular pushing block 20 contacts the covering guiding block 16, the grille frame 4 continues to slide upward. The covering guiding block 16 pushes the circular pushing block 20 to slide in the direction close to the connecting guiding block 15. At this time, until the through hole 9 and the connecting hole 11 are separated, water cannot flow through the through hole 9 and the connecting hole 11, so as to block the water from flowing inside the channel 1. Thus, under the action of the water flow resistance, the grille frame 4 is pushed to continue to move on the fixed plate 2 until the inclined surface of the connecting pushing block 17 contacts the arc surface of the connecting guiding block 15. Then, the connecting guiding block 15 pushes the connecting pushing block 17 to move in the direction close to the covering guiding block 16, and the connecting pushing block 17 synchronously pushes the covering plate 10 to move, so that the through hole 9 and the connecting hole 11 are communicated, and water can pass through the through hole 9 and the connecting hole 11 to pass through the blocking push plate 8; At this time, under the action of the cleaning spring 14, the grille frame 4 is pulled to move on the fixed plate 2, so that the guide shaft 13 is located at the bottom end of the guide groove 12. When the grille frame 4 slides downward and the circular pushing block 20 contacts the covering guiding block 16, the covering guiding block 16 pushes the circular pushing block 20 upward and pulls the tension spring 22 at the same time. Until the circular pushing block 20 slides to the position of the receiving groove 21, after the covering guiding block 16 pushes the circular pushing block 20 into the receiving groove 21, so that the through hole 9 and the connecting hole 11 are kept in a communicating state during the downward movement of the grille frame 4.

[0027] The horizontal driving device includes sliding plates 26 fixedly connected to the two inner side walls of the U-shaped support frame 3. A sliding groove 27 is formed in the sliding plate 26. Slide rails 28 slidably connected to the sliding groove 27 are fixedly connected to both sides of the cleaning plate 45. A pressing spring 29 is arranged between the sliding plate 26 and the cleaning plate 45. During use, the pressing spring 29 pushes the cleaning plate 45 to slide in the direction close to the grille rod 5; A guiding plate 30 is fixedly connected to the guiding frame 23. The guiding plate 30 is arranged as a right trapezoid. Guiding rods 31 matched with the inclined surfaces of the guiding plate 30 are fixedly connected to both ends of the cleaning plate 45; A limiting structure for restricting the cleaning plate 45 from sliding in the direction close to the grille frame 4 is arranged inside the sliding groove 27.

[0028] The limiting structure includes a limiting shaft 32 that is slidably connected up and down to a sliding plate 26. A limiting spring 33 is provided between the limiting shaft 32 and the sliding plate 26. In the initial state, under the action of the limiting spring 33, the limiting shaft 32 is pushed downward to the extreme position, and it is inserted into the inside of the sliding groove 27, so that one end of the limiting shaft 32 catches the slide rail 28, preventing it from sliding in the direction close to the grille rod 5. A unlocking ball 34 is fixedly connected to the top of the limiting shaft 32. A U-shaped guiding clamping plate 35 is slidably connected to one side of the sliding plate 26 close to the guiding frame 23. One end of the opening side of the guiding clamping plate 35 is fixedly connected to a trapezoidal control block 36. A limiting groove 37 that is slidably connected to the limiting shaft 32 is provided in the middle of the trapezoidal control block 36. A supporting spring 38 is installed between the guiding clamping plate 35 and the sliding plate 26. In the initial state, under the action of the supporting spring 38, the guiding clamping plate 35 is pushed in the direction away from the sliding plate 26 to the extreme position, and under the action of the limiting spring 33, the limiting shaft 32 is pushed downward to the extreme position. An unlocking control block 39 for pushing the guiding clamping plate 35 in the direction away from the guiding frame 23 is fixedly connected to the guiding frame 23.

[0029] During use, when sundries such as fallen leaves, weeds, and plastic bags flow along with the water in the channel 1 to the grille rod 5, the sundries are isolated on one side of the grille rod 5. As the sundries increase, they gradually stack on one side of the grille rod 5, blocking the grille rod 5. The water flow inside the channel 1 cannot pass through the grille rod 5 normally. At this time, the water flow inside the channel 1 pushes the sundries, providing a relatively large pressure to push the grille rod 5 and the grille frame 4 to move on the fixing plate 2, pushing the grille frame 4 from the bottom of the guiding groove 12 to the top, thereby stretching the cleaning spring 14 and making the guiding shaft 13 slide from the bottom of the guiding groove 12 to the top, so as to push the grille frame 4 to slide upward. When the grille frame 4 slides upward, the cleaning hanging teeth 6 move upward synchronously with the grille rod 5, thereby driving the sundries intercepted on one side of the grille rod 5 upward; When the grille frame 4 slides upward until the unlocking control block 39 contacts the guiding clamping plate 35, the unlocking control block 39 pushes the guiding clamping plate 35 in the direction close to the sliding plate 26, thereby compressing the supporting spring 38. At this time, the inclined surface of the trapezoidal control block 36 pushes the unlocking ball 34 upward, driving the limiting shaft 32 to move upward synchronously through the unlocking ball 34, compressing the limiting spring 33. At this time, the limiting shaft 32 does not affect the sliding of the slide rail 28 inside the sliding groove 27. Under the action of the pressing spring 29, the cleaning plate 45 is pushed in the direction close to the grille rod 5 until the cleaning teeth 7 are inserted between two adjacent grille rods 5; When the grille frame 4 moves upward until the arc surface of the circular push block 20 contacts the arc surface of the shielding guide block 16, the grille frame 4 continues to slide upward. The shielding guide block 16 pushes the circular push block 20 to slide in the direction close to the communication guide block 15. At this time, until the through hole 9 and the communication hole 11 are separated, water cannot flow through the through hole 9 and the communication hole 11, so as to block the water from flowing inside the channel 1. Thus, under the action of the water flow resistance, the grille frame 4 is pushed to continue to move on the fixed plate 2; When the grille frame 4 slides upward to the limit position, after the inclined surface of the communication push block 17 contacts the arc surface of the communication guide block 15, the communication push block 17 synchronously pushes the shielding plate 10 to move, so that the through hole 9 and the communication hole 11 are communicated. Water can pass through the through hole 9 and the communication hole 11 to pass through the blocking push plate 8. At this time, under the action of the cleaning spring 14, the grille frame 4 is pulled to slide, so that the guide shaft 13 slides in the direction close to the bottom end of the guide groove 12, so that the grille frame 4 slides downward. When the grille frame 4 slides downward and the circular push block 20 contacts the shielding guide block 16, the shielding guide block 16 pushes the circular push block 20 upward and pulls the tension spring 22 at the same time. Until the circular push block 20 slides to the position of the receiving groove 21, after the shielding guide block 16 pushes the circular push block 20 into the receiving groove 21, so that the through hole 9 and the communication hole 11 are kept in a communicating state during the downward movement of the grille frame 4, and the cleaning teeth 7 clean the sundries on the grille rod 5 and the cleaning hanging teeth 6 onto the cleaning plate 45, so that water can pass through the grille rod 5 smoothly; When the grille frame 4 slides downward until the inclined surface of the guide plate 30 contacts the guide rod 31, the guide plate 30 pushes the guide rod 31 to slide in the direction away from the grille frame 4. The guide rod 31 synchronously pushes the cleaning plate 45 to move. At this time, under the action of the support spring 38, the guide clamping plate 35 is pushed to move to the limit position in the direction away from the sliding plate 26. The unlocking ball 34 and the trapezoidal control block 36 are separated from contact. Under the action of the limiting spring 33, the limiting shaft 32 is pushed to slide downward to the limit position. At this time, the limiting shaft 32 blocks one end of the slide rail 28, so that the slide rail 28 cannot slide inside the chute 27.

[0030] The grille rod 5 is set in a C shape, so as to realize that when the grille frame 4 slides downward, the cleaning teeth 7 can clean the sundries from the upper end of the grille rod 5.

[0031] Embodiment 2: Guide frames 23 are slidably connected up and down on both sides of the grille frame 4. The guide frames 23 are slidably connected up and down on the U-shaped support frame 3. The guide shaft 13 is fixedly connected to one side of the guide frame 23 close to the guide groove 12. A pressing bolt 24 for pressing the grille frame 4 is threadedly connected to the guide frame 23; Adjusting threaded shafts 25 are rotatably connected to both sides of the U-shaped support frame 3. The communication push block 17 and the shielding guide block 16 are respectively slidably connected to both sides of the U-shaped support frame 3. The communication push block 17 and the shielding guide block 16 are respectively threadedly connected to the two adjusting threaded shafts 25.

[0032] During use, adjust the height of the grille frame 4 according to the water volume inside the water channel 1. Rotate the pressing bolt 24 to press the grille frame 4 to the current position. At the same time, rotate the adjusting threaded shaft 25 to adjust the height of the connecting push block 17 and the covering guide block 16.

[0033] Embodiment 3: Fixed slots 40 that cooperate with the pressing bolts 24 are provided on both sides of the grille frame 4. During use, insert the pressing bolts 24 into the inside of the fixed slots 40 to fix the height of the grille frame 4.

[0034] Embodiment 4: A storage groove 41 is detachably connected to the fixed plate 2. The storage groove 41 is located below the cleaning plate 45 and is used to collect the sundries on the cleaning plate 45.

[0035] A cross frame 42 is detachably connected between the two sliding plates 26. One end of the cross frame 42 close to the cleaning plate 45 is slidably connected with a scraping plate 43. A abutting spring is installed between the cross frame 42 and the scraping plate 43. Under the action of the abutting spring, the bottom end of the scraping plate 43 is pushed to fit with the cleaning plate 45.

[0036] During use, when the grille frame 4 slides downward, the guide plate 30 pushes the guide rod 31 to slide away from the grille frame 4. At this time, the scraping plate 43 clears the sundries on the cleaning plate 45 into the storage groove 41.
