Flexible seal device for stoplog gate

Abstract

This utility model belongs to the technical field of stacked beam gates, specifically disclosing a flexible water-stop sealing device for stacked beam gates. It includes a gate frame with a slot inside. A sealing block is fixedly connected to the inner bottom wall of the slot. Multiple fixing grooves are formed on the inner wall of the slot. A gate plate is installed inside the slot, and locking blocks are fixedly connected to both ends of the gate plate. The outer surface of the locking blocks contacts the inner wall of the slot. This utility model uses a spring-connected limiting plate on the gate plate. The spring provides initial reset force, and the limiting plate is normally retracted within the gate plate. When the gate plate is pressed down, the inclined surface of the lower surface of the top plate presses against the two limiting plates, causing them to extend to both sides and insert into the fixing grooves on the inner wall of the gate frame's slot. This dual limiting structure—using the slot to limit the locking blocks and the fixing grooves to limit the limiting plates—significantly improves the connection stability between the gate plate and the gate frame, enabling the gate plate to resist stronger water flow impacts.

Description

Technical Field

[0001] This utility model relates to the field of stacked beam gate technology, specifically a flexible water-stop sealing device for stacked beam gates. Background Technology

[0002] In fields such as water conservancy projects, urban water supply and drainage, sewage treatment, hydropower stations, and industrial circulating water systems, stacked beam gates, as a type of water-blocking device that can be flexibly assembled and is easy to transport and install, are widely used in scenarios such as temporary water blocking, maintenance diversion, or water level regulation. Its core working principle is to stack multiple independent stacked beam units one by one into the gate slot, and use the sealing structure between the stacked beam units and between the stacked beam units and the side walls and bottom of the gate slot to block the water flow channel and achieve the purpose of water blocking.

[0003] However, in the use of existing technology, since the gate only limits the stacked beams through the gate slot, when the water volume increases and the water depth increases, the impact of the large water pressure on the gate plate can easily cause the gate plate to separate from the gate, causing the gate to lose its water-blocking function. Therefore, a flexible water-stop sealing device for stacked beam gates is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible water-stop sealing device for a stacked beam gate, so as to solve the problem mentioned in the background art that, since the gate only limits the stacked beams through the gate slot, when the water volume increases and the water depth increases, the impact of the large water pressure on the gate plate can easily cause the gate plate to separate from the gate, thus causing the gate to lose its water-blocking function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible water-stop sealing device for a stacked beam gate, comprising a gate frame, a slot is provided inside the gate frame, a sealing block is fixedly connected to the inner bottom wall of the slot, a plurality of fixing grooves are provided on the inner wall of the slot, a gate plate is provided inside the slot, and a locking block is fixedly connected to both ends of the gate plate, the outer surface of the locking block is in contact with the inner wall of the slot, a sealing groove is provided on the lower surface of the gate plate, the lower surface of the sealing groove is in contact with the upper surface of the sealing block, and a reinforcing device is provided inside the gate plate.

[0006] Preferably, the reinforcement device includes two limiting plates, the outer surfaces of which are slidably connected to the inner wall of the gate.

[0007] Preferably, a first slider is fixedly connected to the surface of each of the two limiting plates, a tension spring is fixedly connected between the two limiting plates, and the surface of the limiting plate is in contact with the inner wall of the fixing groove.

[0008] Preferably, the gate has two first sliding grooves inside, and the interior of each first sliding groove is in contact with the outer surface of a first slider.

[0009] Preferably, a top plate is slidably connected inside the gate, a second slider is fixedly connected to the surface of the top plate, and a gate with the same structure is also provided on the upper surface of the top plate.

[0010] Preferably, the inner wall of the gate is provided with a second sliding groove, and the inner wall of the second sliding groove is in contact with the outer surface of the second slider.

[0011] Preferably, the upper surface of the gate frame is fixedly connected to two fixing blocks, each of the two fixing blocks has a limit groove inside, each limit groove has a limit block slidably connected inside, and the two fixing blocks are rotatably connected to a bidirectional threaded rod inside.

[0012] Preferably, the outer surface of the bidirectional threaded rod is connected to the internal thread of the limiting block, and the internal threads of the two limiting blocks are respectively adapted to the threads on the outer surfaces of the two ends of the bidirectional threaded rod. A rotating disk is fixedly connected to one end of the bidirectional threaded rod, and the lower surfaces of the two limiting blocks are in contact with the upper surface of the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This flexible water-stop sealing device for the stacked beam gate uses a spring-connected limiting plate on the gate plate. The spring provides the initial reset force, and the limiting plate is normally retracted inside the gate plate. When the gate plate is pressed down, the inclined surface of the lower surface of the top plate squeezes the two limiting plates, causing them to extend to both sides and insert into the fixing grooves on the inner wall of the gate frame. Through the dual limiting structure of the locking groove limiting the locking block and the fixing groove limiting the limiting plate, the connection stability between the gate plate and the gate frame is greatly improved, and the gate plate's resistance to water flow impact is significantly enhanced.

Detailed Implementation

[0016] Please see Figure 1-6 This utility model provides a technical solution: a flexible water-stopping sealing device for a stacked beam gate, including a gate frame 1. A slot 4 is provided inside the gate frame 1. A sealing block 14 is fixedly connected to the inner bottom wall of the slot 4. Multiple fixing grooves 10 are provided on the inner wall of the slot 4. A gate plate 5 is installed inside the slot 4. The slot 4 serves to limit the position of the gate plate 5, allowing it to block water flow. Both ends of the gate plate 5 are fixedly connected to locking blocks 9. The outer surface of the locking blocks 9 contacts the inner wall of the slot 4. The shape matching between the locking blocks 9 and the slot 4 helps to better fix the gate plate 5 inside the gate frame 1, allowing it to withstand greater water flow impact. A sealing groove 15 is provided on the lower surface of the gate plate 5. The lower surface of the sealing groove 15 contacts the upper surface of the sealing block 14. The matching between the sealing groove 15 and the sealing block 14 improves the sealing performance of the gate plate 5 against water flow. A reinforcing device is provided inside the gate plate 5.

[0017] The reinforcement device includes two limiting plates 11. The outer surfaces of the two limiting plates 11 are slidably connected to the inner wall of the gate 5. The gate 5 is used to limit the position of the limiting plates 11.

[0018] The surfaces of the two limiting plates 11 are fixedly connected to the first sliders 16, and the two limiting plates 11 are fixedly connected to the tension spring 13. The surfaces of the limiting plates 11 are in contact with the inner wall of the fixing groove 10. The tension spring 13 pulls the two limiting plates 11 to move towards the middle position. At the same time, the stability of the gate 5 is further improved by the insertion and engagement between the limiting plates 11 and the fixing groove 10.

[0019] The gate 5 has two first sliding grooves 17 inside, and the inside of each first sliding groove 17 is in contact with the outer surface of a first slider 16. The first sliding groove 17 serves to limit the position of the first slider 16.

[0020] The gate 5 is internally slidably connected to a top plate 12, and a second slider 19 is fixedly connected to the surface of the top plate 12. The upper surface of the top plate 12 is also provided with a gate 5 of the same structure. The top plate 12 contacts the bottom of another gate 5, thereby improving the sealing between the two gates 5.

[0021] The gate 5 has a second sliding groove 18 on its inner wall. The inner wall of the second sliding groove 18 is in contact with the outer surface of the second slider 19. The second sliding groove 18 serves to limit the position of the second slider 19.

[0022] Among them, two fixing blocks 2 are fixedly connected to the upper surface of the gate frame 1. Each fixing block 2 has a limit groove 7 inside. Each limit groove 7 is slidably connected to a limit block 8. A bidirectional threaded rod 3 is rotatably connected inside the two fixing blocks 2. The two fixing blocks 2 serve to limit the position of the bidirectional threaded rod 3.

[0023] The outer surface of the bidirectional threaded rod 3 is connected to the internal thread of the limiting block 8, and the internal threads of the two limiting blocks 8 are respectively matched with the threads of the outer surfaces at both ends of the bidirectional threaded rod 3. A rotating disk 6 is fixedly connected to one end of the bidirectional threaded rod 3. The lower surfaces of the two limiting blocks 8 are in contact with the upper surface of the clamping block 9. The two limiting blocks 8 are used to squeeze the clamping block 9 and the gate 5, so that the multiple gates 5 are tightly connected.

[0024] Working principle: In use, the operator first aligns the locking blocks 9 at both ends of the gate 5 (used to block water) with the locking groove 4, and then inserts multiple gates 5 into the locking groove 4 in sequence, so that the sealing block 14 is inserted into the sealing groove 15 at the bottom of the gate 5. At the same time, the upper surface of the top plate 12 in the bottom gate 5 is inserted into the sealing groove 15 on the lower surface of the top gate 5, so that multiple gates 5 and the gate frame 1 are sealed. Then, the operator rotates the rotating disk 6, which drives the bidirectional threaded rod 3 to rotate. At this time, the bidirectional threaded rod 3 and the two limiting blocks 8 are inside the... The threaded drive causes the two limiting blocks 8 to move towards the center position under the limiting action of the limiting groove 7. During this process, the inclined surface of one end of the limiting block 8 contacts the upper surface of the top locking block 9, pressing against the upper surface of the locking block 9. This causes the locking block 9 and the gate plate 5 to move downward under the limiting action of the locking groove 4, causing the gate plate 5 to press against the lower top plate 12. The lower top plate 12 moves into the lower gate plate 5, causing the top plate 12 and the second slider 19 to move under the limiting action of the second sliding groove 18. During this process, the inclined surface of the lower surface of the top plate 12 presses against the limiting plates 11 on both sides. This causes the two limiting plates 11 to move towards both sides of the gate plate 5, stretching the tension spring 13 and causing the limiting plates 11 to move out of the interior of the gate plate 5. As the gate plate 5 moves downward, they are inserted into the interior of the fixing groove 10, further improving the stability between the gate frame 1 and the gate plate 5, allowing the gate plate 5 to resist the impact of stronger water flow.
