Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering equipment manufacturing, and specifically relates to a gate gap adjustment device suitable for situations where there is no water pressure difference or the water pressure difference is small on both sides of the gate. Background Technology

[0002] Among the gates used in existing hydraulic facilities, non-pre-compression gates are the most commonly used. When the gate is closed, water pressure or other external forces act on the water-stopping device, causing it to deform and fit tightly against the gate slot components, thereby blocking the water flow channel and achieving the water-stopping function. During operation, the greater the water head and the greater the water pressure, the tighter the fit between the water-stopping device and the contact surface, and the better the water-stopping effect. This characteristic makes non-pre-compression gates highly adaptable to environments with large head differences. The hoist is connected to the gate through components such as lifting lugs. Driven by the hoist, the gate moves up and down along a preset track or support, realizing the opening and closing of the gate. During the opening and closing process, the water-stopping device will correspondingly separate or fit against the contact surface to adapt to different working states of the gate. The opening and closing operation is relatively simple, without the need for complex pre-compression adjustments. Water-stopping and water-discharging functions can be achieved simply by controlling the raising and lowering of the gate through the hoist, improving the gate's operating efficiency and ease of operation.

[0003] In non-pre-pressurized gates, the thickness of the gate leaf is slightly smaller than the thickness of the gate slot. The gate's water-stopping mechanism works by the upstream water pressure pushing the gate leaf towards the downstream gate slot, where a water seal presses against the slot, thus blocking the water flow between the upstream and downstream sides. However, in practical applications, there are sometimes situations where there is no water pressure difference between the two sides of the gate, such as when the water level is very low or during the dry season. In these cases, due to the lack of or small water pressure difference, the water seal cannot be tightly pressed against the gate slot when the gate leaf reaches the bottom sill. When the gate leaf is at the bottom sill, the friction between the gate leaf and the sill prevents the water seal from being pushed tightly against the gate slot even with subsequent water pressure. A gap appears between the gate leaf and the gate slot, allowing water to flow through, resulting in a poor water-stopping effect. Utility Model Content

[0004] One object of this invention is to provide a gate gap adjustment device to solve at least one of the above-mentioned problems in the prior art.

During the descent of the gate leaf 20, the gate gap adjustment device 30 can move the gate leaf 20 in the direction of water flow (the arrow in the figure indicates the direction of water flow), so that the water seal of the gate leaf 20 can fit tightly against the gate groove 10, ensuring a better water-stopping effect.

[0040] Figure 2-3 The illustration schematically shows the installation structure of a gate gap adjusting device according to one embodiment of the present invention.

[0041] refer to Figure 2-3 As shown, near the side beam webs at the four corners of the gate leaf 20, a limiting frame 37 is respectively set on the gate body structure of the gate leaf 20 to limit the movement trajectory of the moving parts of the gate gap adjustment device 30, and the gate gap adjustment device 30 is fixed by bolts and nuts.

[0042] Figures 4-6 The diagram schematically illustrates the structure of a gate gap adjusting device according to one embodiment of the present invention.

[0043] refer to Figures 4-6 As shown, the gate gap adjusting device 30 includes a guide frame 31, rollers 33, roller frame 32, and elastic device 35.

[0044] The guide frame 31 is located on the side of the door leaf 20 facing the upstream of the water flow.

[0045] Roller 33 is mounted on roller frame 32.

[0046] The elastic device 35 is mounted on the guide frame 31. The elastic force of the elastic device 35 can drive the roller frame 32 to make the roller 33 abut against the inside of the door groove 20.

[0047] The gate gap adjustment device of this utility model can replace water pressure when there is no water pressure difference or the water pressure difference is small on both sides of the gate. The elastic component will push the roller frame to move along the guide frame, so that the roller can push against the gate groove, thereby making the gate leaf close to the gate groove, so that there is no gap between the gate leaf and the gate groove, thus ensuring the water-stopping effect of the gate.

[0048] In this embodiment, the guide frame 31 is configured as a semi-frame shape, with a U-shaped groove 38 symmetrically arranged at each of its two free ends, the opening of the U-shaped groove 38 facing the upstream side of the water flow. The roller shaft 34 of the roller 33 is respectively disposed in the two U-shaped grooves 38, and the roller shaft 34 can move along the U-shaped grooves 38. The fixed end of the guide frame 31 is disposed on the base 39, which is fixedly connected to the door leaf 20.

[0049] The elastic device 35 is located at the rear end inside the guide frame 31, and the roller frame 32 is located at the front end inside the guide frame 31. One end of the elastic device 35 is connected to the guide frame 31, and the other end is connected to the roller frame 32. This arrangement allows the roller shaft 34 to reciprocate within the U-shaped groove 38 without disengaging from it.

[0053] A washer 36 is provided at the end where the elastic device 35 is connected to the guide frame 31.

[0054] In this embodiment, the elastic device 35 is a compression spring. One end of the compression spring is connected to the guide frame 31, and the other end is connected to the roller frame 32. The elasticity of the compression spring allows the roller frame 32, roller shaft 34, and roller 33 to move back and forth as a whole, while the roller shaft 34 can move along the U-shaped groove 38. The roller 33 can continuously abut against the inner side of the gate slot 10, so that the other side of the gate leaf 20 can always fit against the other side of the gate slot 10, thus achieving the function of stopping water even during the dry season or when there is no water pressure difference or the water pressure difference on both sides of the gate is relatively small. In other embodiments, the elastic device 35 can also be an elastic component such as a pneumatic cylinder or a hydraulic cylinder.
