Description

Technical Field

[0001] This application relates to the field of medical imaging technology, and in particular to a hydraulic gate water-stopping device with a double-layer sealing structure. Background Technology

[0002] A sluice gate is a movable control structure installed at the opening of a hydraulic structure (such as an overflow dam, a bank spillway, a spillway, a hydraulic tunnel, a sluice gate, etc.). It is used to regulate flow, control upstream and downstream water levels, discharge floodwater, discharge sediment, release ice and floating debris, and transport ships. It is an important component of hydraulic structures. The function of the water-stopping device is to block the gap between the gate leaf and the surrounding area of ​​the opening after the gate is closed, so as to prevent water from seeping and spraying out of the gap. For high-head gates, seepage water spraying can cause cavitation of the water-stopping seat and cause gate vibration.

[0003] Existing hydraulic gate sealing devices with double-layer sealing structures often only employ a single-layer sealing structure during operation. A single-layer sealing structure is more susceptible to wear and corrosion, leading to damage or aging. This not only shortens its service life but also causes water leakage, reducing the gate's sealing performance. Furthermore, it requires frequent maintenance and replacement, increasing costs and potentially disrupting the normal operation of the hydraulic project. Therefore, this paper proposes a hydraulic gate sealing device with a double-layer sealing structure to address these issues. Summary of the Invention

[0004] This embodiment provides a water-stopping device for a hydraulic gate with a double-layer sealing structure to solve the problem that in use, only a single-layer sealing structure is often set. A single-layer sealing structure may be more susceptible to wear and corrosion, resulting in damage or aging. This not only shortens its service life but also causes water leakage, reducing the sealing performance of the gate. In addition, it requires frequent maintenance and replacement, which not only increases costs but may also affect the normal operation of the hydraulic project.

[0005] According to one aspect of this application, a water-stopping device for a hydraulic gate with a double-layer sealing structure is provided, including a gate frame, the gate frame having a first insertion slot and two second insertion slots inside, two first insertion blocks fixedly installed at the bottom of the gate body, and two second insertion blocks fixedly installed on both the left and right sides of the gate body, a second sealing layer being provided inside the first insertion slot and the two second insertion slots, and a first sealing layer being provided on the gate body.

[0006] Furthermore, two first plug-in blocks can be inserted into the interior of the first plug-in slot, and both second plug-in blocks can be slidably connected to the second plug-in slot.

[0007] Furthermore, the cross-sections of the first insertion slot and the two second insertion slots are all U-shaped.

[0008] Furthermore, screens are provided on both sides of the gate body, and guide blocks are fixedly installed on both sides of the two screens.

[0009] Furthermore, the first sealing layer is made of synthetic rubber material.

[0010] Furthermore, the second sealing layer is made of a rubber-plastic composite material.

[0011] Furthermore, the gate frame is provided with multiple guide grooves inside, and multiple guide blocks are slidably connected to the guide grooves.

[0012] Through the above embodiments of this application, by setting a first sealing layer and a second sealing layer inside the gate body and the gate frame respectively, the first sealing layer and the second sealing layer are independent of each other, but work together. When one sealing layer is damaged or aged, the other sealing layer can still play a role, thereby providing double protection to ensure the water-stopping effect of the gate. When the gate is closed, both sealing layers can be tightly attached to the gate body and the gate frame groove, thereby effectively preventing water from leaking through the gaps and greatly improving the sealing performance of the gate.

[0013] By setting up two screens, suspended solids, impurities, and garbage in the water can be filtered out, preventing them from entering the gate and keeping the gate clean and unobstructed. This helps reduce leakage problems caused by impurity accumulation, improves the water-stopping effect, and avoids difficulties in opening and closing the gate or malfunctions caused by impurity blockage. This helps improve the safety of water conservancy projects and ensures their stable operation. Attached Figure Description

[0027] Please see Figure 1-5 As shown, a water-stopping device for a hydraulic gate with a double-layer sealing structure includes a gate frame 1 and a gate body 6. The gate frame 1 has a first insertion groove 7 and two second insertion grooves 11 inside. Two first insertion blocks 2 are fixedly installed at the bottom of the gate body 6. Two second insertion blocks 10 are fixedly installed on both the left and right sides of the gate body 6. A second sealing layer 5 is provided inside the first insertion groove 7 and the two second insertion grooves 11. A first sealing layer 3 is provided on the gate body.

[0028] The first insertion slot 7 can accommodate two first insertion blocks 2, and both second insertion blocks 10 can be slidably connected to the second insertion slot 11.

[0029] The cross-sections of the first insertion slot 7 and the two second insertion slots 11 are all U-shaped.

[0030] Both sides of the gate body 6 are provided with screens 4, and guide blocks 8 are fixedly installed on both sides of the two screens 4. The screens 4 can filter out suspended solids, impurities and garbage in the water, preventing them from entering the gate, thereby keeping the gate clean and unobstructed. This helps to reduce leakage problems caused by the accumulation of impurities in the gate, improves the water-stopping effect, and avoids difficulties in opening and closing the gate or malfunctions caused by impurities clogging it. This helps to improve the safety of water conservancy projects and ensure their stable operation.

[0031] The first sealing layer 3 is made of synthetic rubber material, which has good elasticity and wear resistance and can withstand the scouring of water flow and the opening and closing operation of the gate.

[0032] The second sealing layer 5 is made of rubber-plastic composite material, which combines the elasticity of rubber and the corrosion resistance of plastic, providing higher sealing performance and durability.

[0033] The gate frame 1 has multiple guide grooves 9 inside, and multiple guide blocks 8 are slidably connected to the guide grooves 9, so that the two screens can be installed and disassembled for cleaning, which helps to improve the working efficiency of the gate and ensure the normal operation of the water conservancy project.

[0034] In use, this application utilizes an external drive system to open or close the gate body. The first sealing layer 3 and the second sealing layer 5 are independent yet work together. When one sealing layer is damaged or aged, the other sealing layer can still function, providing double protection to ensure the gate's water-stopping effect. When the gate is closed, both sealing layers can fit tightly against the gate body 6 and the gate frame 1 groove, effectively preventing water leakage through gaps and greatly improving the gate's sealing performance. The first sealing layer 3 and the second sealing layer 5 can adapt to changes in water pressure, flow velocity, and water quality conditions. By setting two screens 4, the screens 4 can filter out suspended solids, impurities, and garbage in the water, preventing them from entering the gate, thus keeping the gate clean and unobstructed. This helps reduce leakage problems caused by impurity accumulation, improves the water-stopping effect, and avoids difficulties in opening and closing the gate or malfunctions caused by impurity blockage. This helps improve the safety of the water conservancy project and ensures its stable operation. When cleaning and maintaining the screens 4, the two guide blocks 8 can be removed from the inside of the guide groove 9, allowing maintenance personnel to easily disassemble and clean the screens, which helps improve the working efficiency of the gate and ensures the normal operation of the water conservancy project.

[0035] The advantages of this application are:

[0036] 1. By setting a first sealing layer 3 and a second sealing layer 5 inside the gate body 6 and the gate frame 1 respectively, the first sealing layer 3 and the second sealing layer 5 are independent of each other, but work together. When one sealing layer is damaged or aged, the other sealing layer can still play a role, thus providing double protection to ensure the water-stopping effect of the gate. When the gate is closed, both sealing layers can be tightly attached to the gate body and the gate frame groove, thereby effectively preventing water from leaking through the gaps and greatly improving the sealing performance of the gate. At the same time, the first sealing layer 3 and the second sealing layer 5 can adapt to changes in water pressure, water flow speed and water quality conditions.

[0037] 2. By setting two screens 4, the screens 4 can filter out suspended solids, impurities and garbage in the water, preventing them from entering the gate, thus keeping the gate clean and unobstructed. This helps reduce leakage problems caused by impurity accumulation, improves the water-stopping effect, and avoids difficulties in opening and closing the gate or malfunctions caused by impurity blockage. This helps improve the safety of water conservancy projects and ensures their stable operation.
