Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically a leak-proof pump gate sealing component. Background Technology

[0002] Pump gates are common facilities in water conservancy projects, combining the functions of pumping stations and sluice gates. They are mainly used for water level regulation, flood control and drainage, irrigation water diversion, and ecological water replenishment. When in use, pump gates need to be sealed to prevent leakage, avoid waste of water resources, and prevent structural damage, foundation seepage and deformation.

[0003] Existing leak-proof pump gate sealing assemblies typically use a sealing gasket between the gate and the frame for sealing. While this prevents leakage, the gasket may age over time, making it easier for leaks to occur between the gate and the frame. Therefore, the gasket needs to be replaced after a period of use. However, during replacement, the contact surfaces between the gate and the frame may be damaged by bumps, scratches, or other damage, causing the gap between the gate and the frame to widen and making it easier for leaks to occur.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] Examples, such as Figures 1-8 As shown, a leak-proof pump gate sealing assembly includes a gate 1 and a frame 2, as well as a sealing mechanism and a moving mechanism, wherein the gate 1 is slidably disposed inside the frame 2.

[0031] The sealing mechanism includes two sealing components, two pressing components, two limiting components, two resetting components, and four pressing plates 19. The two sealing components are respectively arranged on both sides of the frame 2, each pressing component is arranged on one side of a sealing component, each limiting component is arranged on one side of a sealing component, and the four pressing plates 19 are respectively arranged on the two pressing components, and each resetting component is arranged on one side of a pressing component.

[0032] The moving mechanism includes a connecting frame 8, a driving component, and a guiding component. The connecting frame 8 is fixedly installed on the top of the gate 1, the driving component is installed on the top of the frame 2, and the guiding component is installed between the gate 1 and the frame 2.

[0033] like Figures 1-8 As shown, the driving component includes a motor 3, a reel 4, a steel rope 6, a pull ring 7, a horizontal plate 9, a clearance groove 10, and two fixed plates 5. The horizontal plate 9 is fixedly installed on the top of the frame 2, and both fixed plates 5 are fixedly installed on the top of the horizontal plate 9. The motor 3 is fixedly installed on one side of one of the fixed plates 5. The reel 4 is rotatably installed between the two fixed plates 5, and one end of the reel 4 is fixedly connected to the output end of the motor 3. The clearance groove 10 is opened on the top of the horizontal plate 9 and is located between the two fixed plates 5. One end of the steel rope 6 is wound on the reel 4, and the other end of the steel rope 6 passes through the clearance groove 10 and is fixedly connected to the pull ring 7. The pull ring 7 is fixed on the connecting frame 8.

[0034] When the pump gate needs to be closed, the controller controls the motor 3 to work, which drives the reel 4 to rotate and release the steel rope 6. The gate 1 slides inside the frame 2 under its own weight. When the gate 1 moves, it will drive multiple pressure plates 19 to move simultaneously. When the gate 1 moves to the bottom of the frame 2, the multiple pressure plates 19 will descend simultaneously. During the descent of the pressure plates 19, they will come into contact with the inclined plates 14. The multiple pressure plates 19 will squeeze the two inclined plates 14, causing the two sealing components to move closer to the gate 1 and seal the connection between the gate 1 and the frame 2, preventing water from flowing out through the gap between the gate 1 and the frame 2.

[0035] like Figures 1-8 As shown, the guide component includes two guide rods 11, two guide grooves 12 and two sealing blocks 13. Each guide groove 12 is opened on the horizontal plate 9. Each guide rod 11 is fixedly installed on the top of the gate 1 and each guide rod 11 is slidably connected to a guide groove 12. Each sealing block 13 is fixedly installed on the top of a guide rod 11.

[0036] When the gate 1 moves, it will drive the two guide rods 11 to move simultaneously. The two guide rods 11 guide the movement of the gate 1 to prevent the gate 1 from deviating during lifting and lowering, which would affect the sealing.

[0037] like Figures 1-8 As shown, each sealing component includes a sealing horizontal plate 15, two sealing vertical plates 16, a U-shaped strip 17, and a U-shaped groove 18. The sealing horizontal plate 15 is located on one side of the frame 2. Each sealing vertical plate 16 is fixedly located on the top of the sealing horizontal plate 15. The U-shaped strip 17 is fixedly located on one side of the sealing vertical plate 16 and the sealing horizontal plate 15. The U-shaped groove 18 is opened on one side of the gate 1. The U-shaped strip 17 and the U-shaped groove 18 are engaged and connected. It should be noted that each sealing vertical plate 16 and the sealing horizontal plate 15 is provided with a sealing strip on the side near the gate 1. Each sealing horizontal plate 15 and the sealing vertical plate 16 is provided with a sealing strip on one side.

[0038] When the pressure plate 19 descends, it will squeeze the inclined plate 14 closer to the frame 2. When the inclined plate 14 moves, it will drive the sealing horizontal plate 15 to move at the same time. The sealing horizontal plate 15 will drive the two sealing vertical plates 16 to move. By opening a U-shaped groove 18 on the surface of the frame 2, when the sealing horizontal plate 15 and the two sealing vertical plates 16 are close to the frame 2, the U-shaped strip 17 on one side of the sealing horizontal plate 15 and the two sealing vertical plates 16 will enter the U-shaped groove 18 to lock together, thereby strengthening the sealing. By reinforcing both sides of the gate 1, the possibility of leakage between the gate 1 and the frame 2 is greatly reduced.

[0039] like Figures 1-8As shown, each pressing component includes an inclined plate 14 and two fixing blocks 26. The inclined plate 14 is fixedly installed on the side of the sealing cross plate 15 away from the frame 2. Each fixing block 26 is fixedly installed on one side of the gate 1. Each pressing plate 19 is fixedly installed on one side of a fixing block 26. It should be noted that the bottom surface of the pressing plate 19 is provided with a first inclined surface, and the top surface of the inclined plate 14 is provided with a second inclined surface. When the first inclined surface and the second inclined surface come into contact with each other, they will press against each other.

[0040] When the gate 1 moves, it will drive the multiple fixed blocks 26 fixed on the surface to move. The fixed blocks 26 will drive the lower pressure plate 19 to move. When the gate 1 moves to the bottom of the frame 2, the lower pressure plate 19 will press the inclined plate 14 to the maximum, so that the sealing horizontal plate 15 is close to the frame 2, and seals the frame 2 and the gate 1.

[0041] like Figures 1-8 As shown, each limiting component includes two sliding holes 23, two sliding plates 20, two guide rails 21, and two guide plates 22. Each sliding hole 23 is opened on one side of the frame 2. Each sliding plate 20 is fixedly installed on the top of a sealing vertical plate 16, and each sliding plate 20 is slidably connected to a sliding hole 23. Each guide rail 21 is fixedly installed on one side of the gate 1. Each guide plate 22 is fixedly installed at one end of the sealing horizontal plate 15, and each guide plate 22 is slidably connected to a guide rail 21. When the sealing horizontal plate 15 moves, it will drive the two guide plates 22 to move. The guide rails 21 guide the movement of the guide plates 22 to prevent the sealing horizontal plate 15 from deviating during movement. When the sealing vertical plate 16 moves, it will drive the sliding plates 20 to move simultaneously. The sliding holes 23 guide the sliding plates 20 to prevent the sealing vertical plate 16 from deviating during movement.

[0042] like Figures 1-8 As shown, each reset component includes two springs 24 and two mounting plates 25. Each mounting plate 25 is fixedly mounted at one end of a guide rail 21. The two ends of each spring 24 are fixedly connected to the mounting plate 25 and the sealing plate 15 respectively to prevent water flow. When the gate 1 is closed, the sealing plate 15 will move under the action of the lower pressure plate 19. At this time, the spring 24 is stretched. When the gate 1 is opened, the lower pressure plate 19 will disengage from the inclined plate 14, and the sealing plate 15 will move away from the frame 2 and the gate 1 under the action of the spring 24 to facilitate water flow.
