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 ...

Examples

Embodiment 1

[0025] see figure 1 , the present invention provides a technical solution: an elastic water seal device for two-way water stop and vibration reduction of submersible plane gates, including structural steel 1, spring steel 2, P-shaped water seal 3 and water stop rubber 4, and structural steel 1 is fixed Set between the gate body 5, the inner side of the structural steel 1 is fixed with a spring steel 2, the spring steel 2 and the structural steel 1 are fixedly connected by bolts 6, one end of the structural steel 1 is provided with a water-stop rubber 4, and the outer side of the water-stop rubber 4 is provided with Backing plate 7, backing plate 7 is arranged on one side of door slot 8, and P-type water seal 3 is also arranged between gate body 5 and door slot 8.

[0026] In this embodiment, the shape of the spring steel 2 is a semicircle.

[0027] In this embodiment, the structure adjusts the extrusion degree between the water seal and the door slot through the deformation o...

Embodiment 2

[0029] The difference between this embodiment and the first embodiment is that the shape of the spring steel 2 is elliptical, and the semicircular spring steel in the first embodiment is open, and the cavity between the upper and lower water-stop rubbers may be filled with water. Since the incompressibility of the water body itself limits the deformation of the spring steel, thereby affecting the effect of the elastic water seal, the structure adopted in this embodiment can achieve the purpose of improving the effect of the elastic water seal.

Embodiment 3

[0031] The difference between the present embodiment and the second embodiment is: it also includes a viscoelastic material 9, the space inside the spring steel 2 filled with the viscoelastic material 9 adopts a fully sealed structure, and the filling volume of the viscoelastic material 9 accounts for 90% of the space volume , The viscoelastic material 9 consists of 50-70 parts of bromobutyl rubber, 10-15 parts of white carbon black, 8-12 parts of stearic acid, 4-8 parts of mica, 7-15 parts of vulcanized resin, and 7-15 parts of crosslinking agent It is prepared by mixing 18 parts. Since spring steel can store energy, it cannot consume energy by itself. A part of the energy transferred to spring steel by the gate body and water flow cannot be dissipated in a short time. Therefore, viscoelastic damping material is filled inside the closed spring steel , dissipating energy directly through the damping material.

[0032] The using method of the present invention comprises the fol...
