[0022] The utility model provides a gate reverse support device with a pressure relief function, which is used when the gate is closed and when the fluid pressure on the downstream side is greater than the fluid pressure on the upstream side, it can relieve the fluid pressure on the downstream side to ensure safety. Figure 1 and Figure 2 , a gate reverse support device with pressure relief function, comprising a gate slot slideway 1 and a gate reverse support member; the gate reverse support member comprises a slider 2, a slider box 3, a support 4, a limit block 5, a compression spring 6 and a rotating member;

[0023] The gate slot slideway 1 is arranged on the inner wall of the gate slot; the gate leaf is movable in the gate slot. The gate reverse support is arranged on the side of the gate leaf facing the gate slot slideway 1; the slider box 3 is arranged horizontally, and the slider 2 is slidably installed on one end of the slider box 3 facing the gate slot slideway 1; the end of the slider 2 adopts a slope structure, and the slider 2 can slide along the gate slot slideway 1; the other end of the slider box 3 is rotatably installed on the support 4 through the rotating member, and the support 4 is fixed to the inner wall of the gate leaf; the compression spring 6 is installed inside the slider box 3, one end of the compression spring 6 is fixed to the inner side of the slider 2, and the other end is fixed to the bottom of the slider box 3; when the compression spring 6 is naturally not subjected to external force, the end of the slider 2 extends to the outside of the slider box 3, and when in working state, the slider 2 is stuck in the downstream side position of the gate slot slideway 1; the limit block 5 is fixed to the support 4 and is located at the upstream side position of the slider box 3, limiting the rotation of the slider box 3 to the upstream side around the rotating member. The limiting block 5 is installed on the support 4 in a detachable manner.

[0024] The rotating member includes a hinge shaft 7 and a torsion spring 8; the hinge shaft 7 is installed between the slider box 3 and the support 4, so that the slider box 3 rotates toward the downstream side around the hinge shaft 7; the torsion spring 8 is arranged on the hinge shaft 7 to provide resistance to the rotation of the slider box 3 around the hinge shaft 7, and the resistance can be adjusted by the torsion spring 8. By adjusting the torsion spring 8, the elastic force of the torsion spring 8 in the working position can be adjusted, thereby adjusting the pressure relief pressure.

[0025] In the present application, the slider 2 is installed in the slider box 3 and is connected to the slider box 3 through a compression spring 6. The slider 2 can slide back and forth in the slider box 3. The end of the slider 2 adopts a slope structure, and automatically resets through reciprocating motion under the gate's own weight or upstream water pressure.

[0026] The utility model provides a gate reverse support device with pressure relief function, and its working principle is:

[0027] (1) Figure 3 The figure shows a schematic diagram of the gate reverse support device in working state. Figure 3 In the structure, ABCD forms a gate slot structure, and the gate leaf can move within a certain range in the gate slot structure. In the working state, under the action of the water pressure on the upstream side, the gate leaf is located near the downstream side of the gate slot. At this time, the area E between the gate leaf and the downstream side of the gate slot is sealed and cannot pass water. Therefore, after the water passes through area F from the upstream side, it flows into the gate slot and is blocked by area E, achieving the effect of blocking the upstream water;

[0028] (2) When the water pressure on the downstream side of the gate is greater than the water pressure on the upstream side, if it does not reach the design value, the slider box 3 cannot rotate toward the downstream side around the hinge shaft 7 due to the action of the torsion spring 8, thereby preventing the gate leaf from moving toward the upstream side.

[0029] When the water pressure on the downstream side of the gate is greater than the water pressure on the upstream side and reaches the design value, the gate leaf is pushed to overcome the resistance of the torsion spring 8 and move upstream. When the gate leaf moves upstream, the slider box 3 rotates toward the downstream side around the hinge shaft 7 and turns into Figure 4 The pressure relief process status shown;

[0030] through Figure 4 After that, it finally turns into Figure 5 Pressure relief condition shown. Figure 4 and Figure 5 In the state shown, the area E between the gate leaf and the downstream side of the gate slot increases and water flows through. Therefore, after the downstream side water passes through the area E and the gate slot, it flows out from the area between the gate leaf and the upstream side of the gate slot, achieving the effect of timely unloading the downstream side pressure;

[0031] (3) When the pressure on the downstream side disappears, under the action of the gate's own weight or the upstream water pressure, the inclined surface of the slider 2 of the reverse support device contacts the gate slot slideway 1, and moves toward the slider box 3 under the action of the horizontal component force generated by the inclined surface and compresses the compression spring 6. As the gate leaf moves toward the downstream side, the slider 2 continues to move toward the slider box 3. When the gate leaf drives the slider 2 to move completely to the downstream side of the gate slot slideway 1, the slider 2 pops out of the slider box 3 and resets. Figure 5 The status shown changes to Figure 3 The working state shown realizes the function of blocking water on the upstream side.

[0032] The beneficial effects of the utility model are:

[0033] The utility model provides a gate reverse support device with a pressure relief function, which realizes the gate adaptive pressure relief function through pure mechanical principles. By adjusting the elastic force of the torsion spring in the working position, the pressure relief pressure can be flexibly adjusted.

[0034] The utility model has the advantages of safety, reliability, economic rationality and adaptive operation. When the water pressure on the downstream side is greater than the water pressure on the upstream side and reaches the design value, the gate overcomes the spring resistance of the supporting device and moves toward the upstream side, thereby automatically and timely releasing the water pressure on the downstream side, and realizing the adaptive pressure relief function through pure mechanical principles.

[0035] The embodiments described above are only used to illustrate the technical ideas and features of the utility model, and their purpose is to enable technicians in the field to understand the content of the utility model and implement it accordingly. The patent scope of the utility model cannot be limited only by this embodiment, that is, any equivalent changes or modifications made to the spirit disclosed by the utility model still fall within the patent scope of the utility model.
