Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically a water conservancy engineering gate with a filtration function. Background Technology
[0002] A sluice gate in a water conservancy project is a device used to control water flow. It is commonly used in facilities such as sluice gates, reservoirs, and water diversion canals in water conservancy projects. Its main functions are to regulate water flow, prevent floods, regulate water levels, and maintain the normal operation of irrigation and water supply systems.
[0003] In traditional hydraulic engineering gate systems with filter functions, when replacing the filter screen, the gate must be closed to stop water flow. The bolts securing the filter screen are then loosened with a screwdriver, and the filter screen is removed. When installing a new filter screen, workers use a screwdriver to secure it to the gate.
[0004] Traditional hydraulic engineering gates with impurity filtering functions have some problems in use, such as the filter screen being easily clogged with impurities, the filter screen being cumbersome to replace, and the gate's working environment being relatively complex, which increases the difficulty of the work. Therefore, we propose a hydraulic engineering gate with impurity filtering function. Utility Model Content

[0008] The impurity filtering mechanism includes a chute, a sliding seat, a connecting rod, a fixed seat, a filter frame, and a grid. The chute is located in the middle of the front side of the equipment mounting plate. The sliding seat is slidably connected inside the chute, and the connecting rod is rotatably connected inside the sliding seat. The front end of the connecting rod is rotatably connected to the fixed seat. The filter frame is rotatably connected to the front side of the gate.

[0009] Furthermore, the impurity filtering mechanism also includes a first screw, which is rotatably connected to the inside of the slide groove. The external thread surface of the first screw is threadedly connected to the middle part of the sliding seat, providing transmission power for the movement of the sliding seat.
[0010] Furthermore, it also includes a gate frame, which is disposed on the outside of the gate to restrict the position of the gate.
[0011] Furthermore, an internally threaded cylinder is rotatably connected to the middle of the upper surface of the gate frame, and a torsion valve is provided on the upper side of the internally threaded cylinder to provide power for the up and down movement of the gate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figure 1-4 This embodiment provides a technical solution: a hydraulic engineering gate with a filtering function, including a gate 1 and a filtering mechanism 3;
[0024] Gate 1: It has an equipment mounting plate 2 on the lower middle side of its front side, and also includes a gate frame 7. The gate frame 7 is set on the outside of the gate 1. An internal threaded cylinder is rotatably connected to the middle of the upper surface of the gate frame 7. A torsion valve 6 is provided on the upper side of the internal threaded cylinder. The front side of the gate 1 is provided with evenly distributed reinforcing ribs 9. When the water conservancy project gate needs to be used, the gate frame 7 is installed on the designated work position. Then, according to the work requirements, when the project gate needs to be opened, the torsion valve 6 can be manually turned continuously.
[0025] The impurity filtering mechanism 3 includes a chute 31, a sliding seat 33, a connecting rod 34, a fixed seat 35, a filter frame 36, and a grid 37. The chute 31 is located in the middle of the front side of the equipment mounting plate 2. The sliding seat 33 is slidably connected inside the chute 31. The connecting rod 34 is rotatably connected inside the sliding seat 33. The front end of the connecting rod 34 is rotatably connected to the fixed seat 35. The filter frame 36 is rotatably connected to the front side of the gate 1. The upper side wall of the filter frame 36 is provided with evenly distributed grids 37. The rear side of the lower side wall of the filter frame 36 is fixedly connected to the upper surface of the fixed seat 35. The impurity filtering mechanism 3 also includes a first screw 32, which is rotatably connected inside the chute 31. The external thread surface of the first screw 32 is threadedly connected to the middle of the sliding seat 33, allowing it to pass through the chute. A corrugated protective tube is provided between the top wall of the slide 31 and the upper surface of the sliding seat 33, and a corrugated protective tube is also provided between the bottom wall of the slide 31 and the lower surface of the sliding seat 33. The two corrugated protective tubes cover the exposed part of the first screw 32 and move vertically with the sliding seat 33. The two corrugated protective tubes adapt to expansion and contraction, sealing the first screw 32 in real time to prevent contamination of the external thread surface of the first screw 32. The internal thread of the internal threaded cylinder is connected to the second screw 5. A connecting shaft 4 is fixedly connected between the first screw 32 and the second screw 5. It also includes a retrieval port 8, which is located in the middle of the upper surface of the filter frame 36. When not performing retrieval operations, the retrieval port 8 can be fastened by the cover plate. At this time, it is engaged by the threads of the internal threaded cylinder and the second screw 5. The relationship (a bellows is fixedly connected between the upper end of the gate 1 and the bottom end of the gate frame 7, and a bellows is also provided in the middle between the upper and lower inner walls of the gate 1. These two bellows cover the exposed part of the second screw 5 and adapt to the vertical movement of the gate 1, preventing the external thread surface of the second screw 5 from being contaminated). When the torsion valve 6 is turned, the second screw 5 will pull the gate 1 upward, causing the gate 1 to move upward on the gate frame 7, thereby opening the lower side of the gate 1 and the lower side wall of the gate frame 7, allowing water to flow through. When the second screw 5 rotates, it will drive the first screw 32 to rotate synchronously through the connecting shaft 4. Because the lead of the first screw 32 is less than the lead of the second screw 5, the downward movement speed of the sliding seat 33 is faster. The speed of the downward movement of the sliding seat 33 is much smaller than that of the gate 1. When the sliding seat 33 moves downward, it will push the fixed seat 35 through the connecting rod 34, forcing the fixed seat 35 to change its angle with its upper side as the center, so that the lower end of the fixed seat 35 is in close contact with the lower side wall of the gate frame 7. At this time, when the water flows between the gate 1 and the gate frame 7, the water will pass through the filter frame 36. At this time, the grid screen 37 on the filter frame 36 will filter the debris in the water flow and trap the debris inside the filter frame 36. It should be noted that the impact of the water flow is increased, so the debris trapped by the grid screen 37 will not block it, but will continue to tumble inside the filter frame 36. If there is a lot of debris inside the filter frame 36, the debris inside the filter frame 36 can be retrieved through the retrieval port 8.
[0026] The working principle of the hydraulic engineering gate with impurity filtering function provided by this utility model is as follows: When the hydraulic engineering gate needs to be used, the gate frame 7 is installed in the designated position. Then, according to the work requirements, when the engineering gate needs to be opened, the torsion valve 6 can be manually and continuously turned. At this time, due to the thread engagement between the internal threaded cylinder and the second screw 5, when the torsion valve 6 is turned, the second screw 5 will pull the gate 1 upward, causing the gate 1 to move upward on the gate frame 7, thereby opening the lower side of the gate 1 and the lower side wall of the gate frame 7, allowing water to flow through. When the second screw 5 rotates, it will drive the first screw 32 to rotate synchronously through the connecting shaft 4. Because the lead of the first screw 32 is less than the lead of the second screw 5, the sliding seat 33 moves downward. The speed is much less than the downward movement speed of gate 1. When sliding seat 33 moves downward, it will push fixed seat 35 through connecting rod 34, forcing fixed seat 35 to change its angle with its upper side as the center, so that the lower end of fixed seat 35 is in close contact with the lower side wall of gate frame 7. At this time, when water flows between gate 1 and gate frame 7, the water will pass through filter frame 36. At this time, the grid screen 37 on filter frame 36 will filter the debris in the water flow and trap the debris inside filter frame 36. It should be noted that the impact of water flow is increased, so the debris trapped by grid screen 37 will not block it, but will continue to tumble inside filter frame 36. If there is a lot of debris in filter frame 36, the debris in filter frame 36 can be retrieved through retrieval port 8.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
