Description

Technical Field

[0001] This utility model relates to the field of pump gate technology, and in particular to an integrated structure for offshore pump gates that combines monitoring and scour protection. Background Technology

[0002] The integrated pumping station and drainage gate structure is a modern water conservancy engineering facility developed to address the challenges of complex water environments in coastal and estuarine areas. By deeply integrating pumping stations and drainage gates in terms of structure, function, and control systems, it forms a compact hub, achieving comprehensive efficiency in "coordinated self-drainage and forced drainage, combined flood control and tide blocking, and integrated drainage and water diversion." Its core function is to systematically enhance the region's water security capabilities: during the flood season, it prioritizes gravity drainage based on tidal differences, and quickly switches to forced pump drainage when encountering high tides or heavy rain, completely solving the urban flooding problem caused by the untimely drainage of traditional facilities.

[0003] During tidal surges, high-speed water flow and intense wave pressure can cause impact damage to pump gate valves. The huge dynamic water pressure may cause the gate body to deform, welds to crack, or supporting components to break. The water flow impacts and twists the gate frame or gate groove, damages the water-stop rubber strip, causes serious leakage, and loses the water-blocking function. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing an integrated structure for offshore pump gates that can buffer water flow impacts and balance the forces on both sides of the valve when it is impacted, integrating monitoring and scour protection.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown, this utility model proposes an integrated structure for monitoring and scour protection of a sea outlet pump gate, including a wing wall 1 and a valve 101 slidably installed on the wing wall 1. A seal is formed between the valve 101 and the wing wall 1 to separate the water body. Multiple submersible pumps 102 are fixedly installed on the valve 101. By raising the valve 101, the water level on the side with the higher level can flow to the other side, which can achieve the effect of flood discharge. When the water levels on both sides are equal, drainage is still required. The valve 101 needs to be closed and the submersible pumps 102 are started to discharge the water. Two liquid level sensors 6 are fixedly installed on the wing wall 1. The liquid level sensors 6 are located on both sides of the valve 101. The liquid level sensors 6 can detect whether the liquid level on both sides has reached the safety standard.

[0025] like Figures 1 to 3 As shown, the wing wall 1 is equipped with a lifting assembly for lifting the valve 101. The lifting assembly includes a motor 5 fixedly mounted on the wing wall 1, a winch 501 rotatably mounted on the wing wall 1, and a traction rope 502 fixedly mounted on the winch 501. The other end of the traction rope 502 is fixedly connected to the valve 101. The output shaft of the motor 5 is coaxially fixedly connected to the winch 501. By driving the winch 501 to rotate through the motor 5, the traction rope 502 can be wound, which can drive the valve 101 to rise. When the winch 501 rotates in the opposite direction, the valve 101 can be lowered under its own weight.

[0026] As one implementation method, such as Figures 1 to 3 and Figure 5As shown, the offshore pump gate also includes a buffer plate 2 slidably installed on the valve 101. The buffer plate 2 has multiple arc-shaped holes 201. The two openings of the arc-shaped holes 201 are located on the same side of the buffer plate 2. When a surge occurs, the water flow will first come into contact with the buffer plate 2, and a part of the water flow will enter the interior of the arc-shaped holes 201. Under the guidance of the arc-shaped holes 201, the water flow changes direction and is discharged, which can reduce the impact force of the water flow and prevent the impact force of the water flow from acting directly on the valve 101. The impact force of the water flow is also weakened to a certain extent by changing the flow direction of the water flow.

[0027] As one implementation method, such as Figures 3 to 6 As shown, the outbound pump gate of this embodiment also includes a support assembly installed between the buffer plate 2 and the valve 101, and a transmission assembly installed on the valve 101. When one of the buffer plates 2 moves, the transmission assembly drives the other buffer plate 2 to move synchronously in the same direction. The support assembly allows the buffer plates 2 to move within a certain range, which can adapt to the impact of the water flow. When one of the buffer plates 2 is impacted, the other buffer plate 2 moves synchronously. When the other buffer plate 2 moves, it needs to overcome the water flow resistance. Under the action of the reaction force, the other buffer plate 2 will apply a certain pressure to the valve 101, which can reduce the pressure difference on both sides of the valve 101, thereby effectively preventing the valve 101 from deforming due to excessive pressure on one side.

[0028] Furthermore, the support assembly includes multiple support cylinders 3 fixedly installed on both sides of the valve 101. A slider 301 is slidably installed inside the support cylinder 3. A support shaft 302 is fixedly installed on the slider 301. Multiple support shafts 302 located on the same side are fixedly connected to the buffer plate 2 on the same side. The buffer plate 2 is supported by the support shafts 302, so that the buffer plate 2 can move along the axial direction of the support shaft 302.

[0029] A spring 303 is fixedly installed inside the support cylinder 3. The other end of the spring 303 is fixedly connected to the slider 301. The spring 303 can absorb the impact of water flow and prevent the buffer plate 2 from having a rigid impact with the water flow. When the buffer plate 2 is not affected by external force, it can drive the buffer plate 2 to reset. The support shaft 302 passes through one side of the support cylinder 3 and extends to the outside of the support cylinder 3. The connection between the support cylinder 3 and the support shaft 302 is sealed to prevent water from entering the interior of the support cylinder 3 and to prevent water from contaminating the spring 303.

[0030] Furthermore, the transmission assembly includes a transmission cylinder 4 fixedly installed on both sides of the valve 101. A drive plate 401 is slidably installed inside the transmission cylinder 4. A transmission rod 402 is fixedly installed on the drive plate 401. The transmission rod 402 passes through one side of the transmission cylinder 4 and extends to the outside of the transmission cylinder 4. The transmission rod 402 corresponds to and is fixedly connected to the buffer plate 2. When the buffer plate 2 moves, it will drive the transmission rod 402 to move. The moving transmission rod 402 can drive the drive plate 401 to move.

[0031] It should be noted that a sealing ring 403 is fixedly installed on the drive plate 401, and a sealing treatment is provided at the connection between the transmission cylinder 4 and the transmission rod 402. Both ends of the transmission cylinder 4 are connected through pipes 404. Both the transmission cylinder 4 and the pipes 404 are filled with hydraulic medium. The hydraulic medium is a liquid that cannot be compressed under working conditions. When the buffer plate 2 on one side is impacted and drives the drive plate 401 to move, it will push the hydraulic medium inside the transmission cylinder 4 to flow through the pipes 404. Through the transmission of the hydraulic medium, the drive plate 401 on the other side can be moved, and then the buffer plate 2 on the other side can be moved through the transmission rod 402. The buffer plate 2 overcomes the water resistance reaction force and applies pressure to the valve 101, which can effectively reduce the pressure difference on both sides of the valve 101, thereby protecting the valve 101 from damage by water flow impact.

[0032] In this embodiment, when a surge impact occurs, the water flow will first come into contact with the buffer plate 2, and a portion of the water flow will enter the arc-shaped hole 201. Under the guidance of the arc-shaped hole 201, the water flow will change direction and be discharged, which can reduce the impact force of the water flow, prevent the impact force of the water flow from acting directly on the valve 101, and weaken the impact force of the water flow by changing the flow direction of the water flow.

[0033] When one of the buffer plates 2 is impacted and drives the drive plate 401 to move, it will push the hydraulic medium inside the transmission cylinder 4 to flow through the pipe 404. The transmission of the hydraulic medium can drive the drive plate 401 on the other side to move, and then drive the buffer plate 2 on the other side to move through the transmission rod 402. The buffer plate 2 overcomes the water resistance and applies pressure to the valve 101, which can effectively reduce the pressure difference on both sides of the valve 101, thereby protecting the valve 101 from being damaged by the water flow.

[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
