Sluice gates are needed in the process of water conservancy. In the process of using water conservancy sluice gates, a return flow lifting structure is needed to improve the use effect of water conservancy sluice gates.

[0003] However, most existing technical solutions have the following drawbacks: when the gate is raised and lowered by recirculation, the lifting rod is driven by a motor. Ordinary hydraulic gates are not effective for replacing the gate and are not convenient for cleaning debris in the water. Therefore, this utility model provides a hydraulic gate that can be raised and lowered by recirculation to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic gate that can be raised and lowered for backflow, so as to solve the problems mentioned in the background art, which are that the gate is raised and lowered by a motor driven by a lifting rod, and that ordinary hydraulic gates are not effective in replacing the gate and are not convenient for cleaning debris in the water.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic gate capable of backflow lifting and lowering, comprising a gate frame, a fixed plate installed on the upper side of the frame, and a connecting rod connected to the right side of the fixed plate, a handle fixedly installed on the front side of the connecting rod, a connecting wheel connected to the left side of the connecting rod, a connecting block connected to the lower outer side of the connecting wheel, and a moving rod installed on the middle side of the connecting wheel;

[0006] The mounting block is fixedly installed at the lower end of the moving rod, and the outer side of the mounting block is connected to the gate body. The rear side of the gate body is connected to a replacement structure, and the middle side of the gate body is fixedly connected to a fixing rod.

[0007] A filter plate is installed on the lower middle side of the gate frame, and a connecting rod is connected to the lower front side of the gate frame. A movable scraper is connected to the outer side of the connecting rod, and a limit rod is connected to the lower inner side of the movable scraper. A cylinder is provided on the inner left side of the gate frame, and a blocking plate is fixedly installed at the lower end of the cylinder.

[0008] Preferably, the replacement structure includes a mounting rod, which is mounted on the inner rear side of the gate body via a bearing, and a movable block is connected to the outer side of the mounting rod, and a movable rod is connected to the outer side of the movable block, and a limit block is connected to the front side of the movable rod.

[0009] Preferably, the limiting block and the mounting block are connected by a snap-fit ​​mechanism, and the cross-sectional shape of the limiting block is an "L" shape.

[0010] Preferably, the connecting rod and the connecting wheel form a worm gear structure, and the connecting wheel and the moving rod are connected by a thread.

[0011] Preferably, the connecting wheel and the connecting block are connected by welding, and the connecting blocks are symmetrically distributed about the center line of the moving rod.

[0012] Preferably, the mounting rod and the movable block are connected by a thread, and the movable block and the movable rod are connected by a rotation.

[0013] Preferably, the barrier plate and the gate frame are connected in a sliding manner.

[0014] Preferably, the limiting rod and the movable scraper are connected in a sliding manner, and the movable scraper and the filter plate are connected in an adhesive manner.

[0016] By rotating the handle, the connecting rod rotates on the right side inside the fixed plate. This causes the connecting wheel, which forms a worm gear structure with the connecting rod, to rotate the connecting block on the lower side inside the fixed plate. This causes the moving rod, which is threadedly connected to the connecting wheel, to move upward. The moving rod then causes the mounting block to slide upward, which in turn causes the mounting block to slide upward, facilitating the backflow lifting and lowering of the gate body.

[0017] By rotating the mounting rod, the mounting rod rotates on the rear side of the gate body through the bearing, causing the movable block, which is threadedly connected to the mounting rod, to slide rearward on the rear side of the gate body. This causes the movable rod, which is rotatably connected to the movable block, to rotate, causing the limiting block, which is rotatably connected to the movable rod, to slide outward on the outside of the fixed rod. This causes the limiting block to separate from the outside of the mounting block. Then, by rotating the handle, the handle drives the connecting wheel to rotate, causing the movable rod, which is threadedly connected to the connecting wheel, to slide the mounting block upward. This causes the mounting block to separate from the upper side of the gate body, facilitating the replacement of the gate body.

[0018] The filter plate, fixedly installed on the middle side of the lower end of the gate frame, filters impurities in the water. The motor drives the connecting rod to rotate on the front side of the lower end of the gate frame, causing the movable scraper, which is threadedly connected to the connecting rod, to slide to the left outside the limit rod. This allows the movable scraper to remove impurities from the front side of the filter plate onto the left side of the lower end of the gate frame. The cylinder is then activated, causing the cylinder to drive the baffle plate to slide upward on the left side inside the gate frame, thus discharging the impurities on the left side of the lower end of the gate frame to the inside of the gate frame, facilitating the cleaning of impurities in the water.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6This utility model provides a technical solution: a hydraulic gate capable of backflow lifting and lowering, comprising: a fixed plate 2 installed on the upper side inside the gate frame 1, and a connecting rod 7 connected to the right side inside the fixed plate 2; a handle 18 fixedly installed on the front side of the connecting rod 7; a connecting wheel 8 connected to the left side of the connecting rod 7; a connecting block 9 connected to the lower outer side of the connecting wheel 8; and a moving rod 3 installed on the middle side of the connecting wheel 8. Rotating the handle 18 causes the handle 18 to drive the connecting rod 7 to rotate on the right side inside the fixed plate 2, thereby causing the connecting wheel 8 connected to the connecting rod 7 to drive the connecting block 9 to rotate on the lower side inside the fixed plate 2, thereby causing the moving rod 3 connected to the connecting wheel 8 to move upward, causing the moving rod 3 to drive the mounting block 4 to slide upward, thereby causing the mounting block 4 to drive the gate body 5 to slide upward, facilitating backflow lifting and lowering of the gate body 5;

[0028] Mounting block 4 is fixedly installed at the lower end of moving rod 3, and gate body 5 is connected to the outer side of mounting block 4. Replacement structure is connected to the rear side of the inner side of gate body 5, and fixing rod 17 is fixedly connected to the middle side of the inner side of gate body 5. Rotating the replacement structure causes it to slide outward on the outer side of fixing rod 17, thereby separating the replacement structure from the outer side of mounting block 4. Then, rotating handle 18 causes it to drive connecting wheel 8 to rotate, thereby causing moving rod 3 connected to connecting wheel 8 to drive mounting block 4 to slide upward, thus separating mounting block 4 from the upper side of gate body 5, facilitating replacement of gate body 5. Filter plate 12 is installed on the lower middle side of gate frame 1, and connecting rod 13 is connected to the lower front side of gate frame 1. Connecting rod 13 is connected to the outer side of connecting rod 13. A movable scraper 14 is provided, with a limit rod 19 connected to its lower inner side. A cylinder 20 is provided on the left inner side of the gate frame 1, and a baffle plate 15 is fixedly installed at the lower end of the cylinder 20. The filter plate 12 fixedly installed on the middle side of the lower end of the gate frame 1 filters the impurities in the water. The motor drives the connecting rod 13 to rotate on the front side of the lower end of the gate frame 1, causing the movable scraper 14 connected to the connecting rod 13 to slide to the left outside the limit rod 19. This allows the movable scraper 14 to scrape the impurities on the front side of the filter plate 12 onto the left side of the lower end of the gate frame 1. The cylinder 20 is activated, causing the cylinder 20 to drive the baffle plate 15 to slide upward on the left side of the inner side of the gate frame 1, thereby discharging the impurities on the left side of the lower end of the gate frame 1 into the inner side of the gate frame 1, facilitating the cleaning of impurities in the water.

[0029] When using a hydraulic gate that can raise and lower for backflow, specifically as follows: Figure 1 , Figure 2 and Figure 5In the middle, rotating the handle 18, the connecting rod 7 and the connecting wheel 8 form a worm gear structure, and the connecting wheel 8 and the moving rod 3 are connected by a thread, so that the handle 18 drives the connecting rod 7 to rotate on the right side inside the fixed plate 2, thereby causing the connecting wheel 8, which forms a worm gear structure with the connecting rod 7, to drive the connecting block 9 to rotate on the lower side inside the fixed plate 2. The connecting wheel 8 and the connecting block 9 are connected by welding, and the connecting blocks 9 are symmetrically distributed about the center line of the moving rod 3, thereby causing the moving rod 3, which is threadedly connected to the connecting wheel 8, to move upward, so that the moving rod 3 drives the mounting block 4 to slide upward, thereby causing the mounting block 4 to drive the gate body 5 to slide upward, which facilitates the return flow lifting and lowering of the gate body 5;

[0030] Specific examples Figure 1 , Figure 3 and Figure 4 In the process, rotating the mounting rod 10, which is threadedly connected to the movable block 11, and rotating the movable block 11 to the movable rod 16, allows the mounting rod 10 to rotate within the rear of the gate body 5 via a bearing. This causes the movable block 11, which is threadedly connected to the mounting rod 10, to slide backward within the rear of the gate body 5, thereby causing the movable rod 16, which is rotatably connected to the movable block 11, to rotate. The limiting block 6 is engaged with the mounting block 4, and the limiting block 6 has an "L" shaped cross-section. This allows the limiting block 6, which is rotatably connected to the movable rod 16, to slide outward outside the fixed rod 17, thereby separating the limiting block 6 from the outside of the mounting block 4. Then, rotating the handle 18 causes the connecting wheel 8 to rotate, causing the movable rod 3, which is threadedly connected to the connecting wheel 8, to slide the mounting block 4 upward, thereby separating the mounting block 4 from the upper side of the gate body 5, facilitating the replacement of the gate body 5.

[0031] Specific examples Figure 1 , Figure 3 and Figure 6 In this system, a filter plate 12 fixedly installed on the lower middle side of the gate frame 1 filters impurities in the water. A limiting rod 19 is slidably connected to a movable scraper 14, and the movable scraper 14 is fitted to the filter plate 12. A motor drives a connecting rod 13 to rotate on the lower front side of the gate frame 1, causing the movable scraper 14, which is threaded to the connecting rod 13, to slide to the left outside the limiting rod 19. This allows the movable scraper 14 to scrape the impurities on the front side of the filter plate 12 onto the lower left side of the gate frame 1. A baffle plate 15 is slidably connected to the gate frame 1. When the cylinder 20 is activated, it drives the baffle plate 15 to slide upward on the left side inside the gate frame 1, thus discharging the impurities on the lower left side of the gate frame 1 to the inside of the gate frame 1, facilitating the cleaning of impurities in the water.
