Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a seepage-proof structure for sluice gates and pumping stations. Background Technology

[0002] A pumping station is a device and engineering project that provides hydraulic and pneumatic power with a certain pressure and flow rate. Sluice gates are installed at the water inlet and outlet of the pumping station. Sluice gates are low-head hydraulic structures built on rivers and canals, using valves to control flow and regulate water levels. Currently, most sluice gates use concrete-cast sluice gate bottom plates. Due to the loads during sluice gate operation, the sluice gate bottom plate will inevitably undergo significant vertical and horizontal deformation, easily leading to cracks and reducing its seepage prevention performance. Chinese utility model patent, authorized announcement number CN222206240U, discloses a seepage prevention structure for sluice gate pumping stations. This structure perfectly solves the technical problem of reduced seepage prevention performance of sluice gate bottom plates in existing technologies by setting elastic stress-relief water jackets at the bottom of the gate plate.

[0003] However, the existing technology still has certain defects. For example, the existing technology uses the cooperation of magnetic holes and magnetic bolts to fix the elastic unloading water bag to the gate. As a result, when the gate is opened, the pressure on the water-facing side of the elastic unloading water bag is relatively large, which causes the water-facing side of the elastic unloading water bag to be pressurized on one side, which may lead to separation between the elastic unloading water bag and the gate. Utility Model Content

[0004] The purpose of this utility model is to provide a seepage-proof structure for sluice gate pumping stations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seepage-proof structure for a sluice gate pumping station, including a gate plate, a base fixed to the bottom of the gate plate by a fixing component, and an elastic stress-relief water bag fixed to the bottom end of the base; A fixed pipe is fixed on one side of the base, which is connected to the inner cavity of the elastic pressure relief water bag. A vertical pipe is connected to the body of the fixed pipe. The vertical pipe is fixed to the side of the gate by several buckles. A pressure monitoring device and a pressure reducing valve are connected to the body of the vertical pipe.

[0006] Preferably, both the fixed pipe and the vertical pipe are located on the back side of the gate.

[0007] Preferably, the fixing component includes several vertical slots formed on both sides of the gate, and several inserts are fixed on both sides of the top of the base. The top of the inserts is provided with slots, and the inserts are adapted to the vertical slots. A first screw is fixed to the side wall of the vertical slot. The first screw is adapted to the slot, and a first nut is screwed onto the shaft of the first screw.

[0008] Preferably, the fixing assembly includes several bottom fixing blocks fixed on both sides of the base, several top fixing blocks fixed on both sides of the gate, a second screw that is movably inserted into the top of the bottom fixing block, and a second nut screwed onto the top of the second screw.

[0009] Preferably, the fixing assembly includes several first connecting plates fixed on both sides of the base, and a second connecting plate and a drive box are fixed on both sides of the gate. A rotating shaft is movably connected between the second connecting plate and the drive box. Multiple pull ropes are wound around the shaft body of the rotating shaft, and the bottom end of the pull rope is fixed to the top end of the first connecting plate. The drive box is equipped with a worm gear and worm drive component, which drives the rotating shaft to rotate.

[0010] Preferably, an elastic plate is fixed to the top of the gate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The sluice gate pump station uses a seepage-proof structure and is equipped with a fixing component. The fixing component securely connects the base to the gate, effectively preventing the elastic unloading water tank from separating from the gate when the pressure on the water-facing side is high.

[0012] Meanwhile, a fixed pipe and a vertical pipe are provided, and the fixed pipe and the vertical pipe are located on the back side of the gate. Compared with the existing technology where the vertical pipe is located inside the gate, this design not only simplifies the internal structure of the gate and reduces the processing difficulty, but also allows for inspection and maintenance without disassembling the gate when the vertical pipe or related components malfunction, greatly improving the convenience of equipment maintenance.

[0015] 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.

[0016] Example 1: As Figures 1-2 As shown, this utility model provides a technical solution: a seepage-proof structure for a sluice gate pumping station, including a gate plate 1 set between two gate piers. A lifting component (existing technology, not shown in the figure) for lifting the gate plate 1 is provided on the top of the gate plate 1. A base 2 is fixed to the bottom of the gate plate 1 by a fixing component 6. An elastic unloading water bag 3 is fixed to the bottom end of the base 2. A fixing pipe 4 connected to the inner cavity of the elastic unloading water bag 3 is fixed to one side of the base 2. A vertical pipe 5 is detachably connected to the body of the fixing pipe 4. To facilitate the disassembly of the vertical pipe 5 and the subsequent disassembly of the elastic unloading water bag 3, the fixing pipe... The fixed pipe 4 and the vertical pipe 5 are fixed together by a flange. The vertical pipe 5 is fixed to the side of the gate 1 by several clips. In order to reduce the corrosion of the pipe by water, both the fixed pipe 4 and the vertical pipe 5 are located on the back side of the gate 1. A pressure monitoring device and a pressure reducing valve (existing technology, not shown in the figure) are connected to the pipe body of the vertical pipe 5. The pressure monitoring device will reduce the pressure of the elastic unloading water tank 3 by the pressure reducing valve according to the strong pressure it receives, so as to maintain the stability of the internal pressure of the elastic unloading water tank 3, reduce the risk that the water in the elastic unloading water tank 3 cannot be discharged and will burst the elastic unloading water tank, and improve the service life of the elastic unloading water tank 3.

[0017] The fixing component 6 includes several vertical slots 601 formed on both sides of the gate plate 1. Several inserts 602 are fixed on both sides of the top of the base 2. The top of the inserts 602 is provided with slots 603. The inserts 602 are adapted to the vertical slots 601. A first screw 604 is fixed on the side wall of the vertical slot 601. The first screw 604 is adapted to the slots 603. A first nut 605 is screwed onto the body of the first screw 604. When installing the base 2, first align the inserts 602 with the vertical slots 601 and insert them, so that the first screw 604 passes through the slots 603. Then tighten the first nut 605 to achieve a stable connection between the base 2 and the gate plate 1. This avoids loosening between the base 2 and the gate plate 1 due to unilateral water pressure, thereby preventing the elastic unloading water bag 3 from shifting due to unstable fixing and further ensuring the overall sealing performance of the anti-leakage structure. Meanwhile, the vertical slot 601 provides a guide for the insert block 602, facilitating quick positioning during installation and improving installation efficiency.

[0018] Example 2: Figure 3 As shown, the difference from Embodiment 1 lies in the fixing component 6. In this embodiment, the fixing component 6 includes several bottom fixing blocks 606 fixed on both sides of the base 2, and several top fixing blocks 607 equal in number to the bottom fixing blocks 606 fixed on both sides of the gate plate 1. A second screw 608 is fixed at the top of the bottom fixing block 606 and movably inserted into the top fixing block 607. A second nut 609 is screwed onto the top of the second screw 608. When installing the base 2, the second screw 608 on the bottom fixing block 606 is inserted into the through hole of the top fixing block 607, and then the second nut 609 is tightened. Through the squeezing action between the second nut 609 and the top fixing block 607, the base 2 and the gate plate 1 are tightly fixed. This structure uses a bolt connection, which has high connection strength and is easy to disassemble. When the elastic unloading water bag 3 needs to be replaced or repaired, the base 2 and the gate plate 1 can be separated simply by unscrewing the second nut 609, reducing the maintenance difficulty.

[0019] Example 3: Figure 4As shown, the difference from Embodiment 1 lies in the fixing component 6. In this embodiment, the fixing component 6 includes several first connecting plates 610 fixed to both sides of the base 2. Second connecting plates 611 and a drive box 614 are fixed to both sides of the gate 1. A rotating shaft 612 is movably connected between the second connecting plates 611 and the drive box 614. Multiple pull ropes 613 are wound around the shaft of the rotating shaft 612, and the bottom ends of the pull ropes 613 are fixed to the top ends of the first connecting plates 610. A worm gear and worm drive are installed inside the drive box 614. The worm gear is fixed to the shaft of the rotating shaft 612, and the worm drives the worm gear to rotate, thereby realizing the rotation of the rotating shaft 612. The worm gear and worm drive have a self-locking function, which can keep the position of the rotating shaft 612 unchanged after the drive stops, preventing the pull ropes 613 from loosening due to external forces. When installing base 2, the worm gear and worm drive in drive box 614 drive shaft 612 to rotate, causing pull rope 613 to gradually wind around shaft 612, thereby lifting base 2 upward and tightly fitting it against gate 1. This fixing method can be adapted to different installation requirements by adjusting the tightness of pull rope 613, enhancing the flexibility of fixing component 6. In addition, in order to further improve the sealing performance of the top of gate 1, prevent water from leaking from the gap between the top of gate 1 and the top of gate chamber, and prevent inconsistent rotation speed of worm gears on both sides from causing poor sealing between base 2 and gate 1, an elastic plate 7 is fixed at the top of gate 1. The elastic plate 7 is made of rubber. When gate 1 is fully closed, the elastic plate 7 will be in close contact with the top of gate chamber, filling the gap through its own elastic deformation, effectively blocking the leakage path of water.
