Bidirectional-waterstop and vibration-damping elastic water seal device of down-the-hole planar gate

Abstract

The invention discloses a bidirectional-waterstop and vibration-damping elastic water seal device of a down-the-hole planar gate. The bidirectional-waterstop and vibration-damping elastic water seal device comprises structural steel, spring steel, a P-shaped water seal and waterstop rubber. The structural steel is fixedly arranged in a gate body. The spring steel is fixedly arranged on the inner side of the structural steel and fixedly connected with the structural steel through bolts. The waterstop rubber is arranged at one end of the structural steel. A backing plate is arranged on the outer side of the waterstop rubber and on one side of a gate groove. The P-shaped water seal is further arranged between the gate body and the gate groove. The bidirectional-waterstop and vibration-damping elastic water seal device of the down-the-hole planar gate is novel in structural design, and water leakage at the top of the gate can be effectively prevented and vertical vibration of the gate can be weakened in the waterstop and operating process of the down-the-hole planar gate.

Description

technical field [0001] The invention relates to a two-way top-stop water sealing device applied to submerged-hole plane gates, in particular to an elastic water-sealing device for two-way water-stopping and vibration-reduction of submersible plane gates. Background technique [0002] At present, the water seal forms applied to submersible gates mainly include: (1) conventional water seals, such as P-type and mountain-type water seals, which can achieve the effect of water-stopping by adopting the method of preloading; (2) the top of the door to prevent water jets Elastic water seal, this type of water seal is also a kind of elastic water seal. The principle is that the rubber water seal is pressed against the water pressure to deform and then compress the gate panel to prevent water jets. It is generally used at the same time as the conventional water seal; (3) Stamping water seal up. The stamping water seal is different from the previous two water seal structures. It uses ...

Problems solved by technology

[0003] The conventional water seal adopts the method of preloading to control the leakage of the water seal, but due to the deformation of the gate body during the operation of the gate, the problems of the lintel structure and water-stop construction, and the deformation of the water seal itself under the action of water pressure, the water seal leaks and shoots water. It cannot effectively stop the water; the combination of the anti-splash elastic water seal and the conventional water seal can effectively prevent water jetting and water leakage from the top of the door. On the other hand, the water head required by the anti-spray elastic water seal is relatively high, and it is difficult to play a role with a low water head; for stamping water seals, the structure of the water seal is more complicated, and an independent pressurization system is required, and it can only Install on door slot

For the down-the-hole plane gate, the gate slot is a vertical shaft structure, and the f
