Abstract
The utility model relates to a device which makes use of the gas pressure to carry out gate seal, concretely relates to a gas-filled type seal gate. The gate comprises a pier, a gate slot and a gate body; a gas-filled capsule which is connected with the gate body is arranged in the gate slot. As the water seal principle of the gate is to make use of the high-pressure gas to aerate the gas-filled capsule in order to seal water and the water seal effect is favorable; the gate is raised when the gas is exhausted, and the opening resistance of the gate is small; the backwater can carry out the upper course water seal and the lower course water seal simultaneously in the gate slot and the water seal has no directionality. The gate is especially suitable to a water storage ebb gate in the coastal areas.
Description
Technical field:
The utility model relates to a kind of device that utilizes gas pressure to carry out gate sealing, specifically a kind of air filling type backwater gate.
Background technology:
At present, sluice gate sealing adopts P type, double-P type or plate rubber bodies sealing more.Its principle is to utilize the elasticity of rubber, with external force rubber bodies is suppressed on gate pier, to reach stagnant water effect.This water-stopping method working pressure is excessive, can increase the gate opening resistance; Pressure is too small then can sealing not tight.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve the described deficiency of background technology, and provides a kind of stagnant water effect good and do not influence the air filling type backwater gate of gate opening.
The technical scheme that realizes the foregoing invention purpose is: this gate comprises gate pier, gate slot, sluice gate body, is provided with the aerated capsule that is connected with sluice gate body in this gate slot.
According to the air filling type backwater gate that the technical program realizes, owing to its sealing principle is to utilize gases at high pressure to make the aerated capsule inflation reach sealing, so stagnant water effect is good; Lock is carried in exhaust, and the gate opening resistance is little; Sealing can be made the upstream sealing simultaneously in gate slot, also can make the downstream sealing, does not have directionality, is specially adapted to the anti-tide lock of coastal area retaining.
Description of drawings:
Fig. 1 is the structural representation under the utility model sealing state.
The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
The described air filling type backwater gate of present embodiment is made up of gate pier 1, gate slot 2, sluice gate body 3, aerated capsule 4, and this aerated capsule 4 places in this gate slot 2, and fixedlys connected with sluice gate body 3.When closing the lock retaining, sluice gate body 3 is fallen and closed shutter along gate slot 2, inflate in aerated capsule 4 with air pump, high pressure gas makes aerated capsule 4 be close to sluice gate body 3 and gate slot 2 walls, thereby forms tight sealing.During starting gate, the gas in the first emptying aerated capsule 4 reduces the gate opening resistance, mentions sluice gate body 3 again.
Claims (1)
1, a kind of air filling type backwater gate comprises gate pier, gate slot, sluice gate body, it is characterized in that being provided with in this gate slot the aerated capsule that is connected with sluice gate body.
