Hydraulic flat -turnable confinement and flooding door

Abstract

The invention relates to the field of a flat opening vertical rotating type protection gate, in particular to a hydraulic flat opening vertical rotating type protection sealing flood gate arranged in a main line interval of a subway. The hydraulic flat opening vertical rotating type protection sealing flood gate comprises a pump station and a valve group, wherein the pump station comprises an oil tank, a manual pump, a motor, an oil pump, an oil suction oil filter and an oil return oil filter, and the valve group comprises a first group of valves, a second group of valves and a third group of valves in parallel arrangement. The hydraulic flat opening vertical rotating type protection sealing flood gate has the advantages that the fast and safe closing can be realized during subway tunnel water inlet; the requirements of driving the pump station and operating the flood gate by electric power at ordinary times can be met; the characteristic that the flood gate can still be normally opened when the first set of pump station fails is also realized; the requirement of two-mode operation of completing the starting and closing of the flood gate through operating the manual pump in an equipment room and adopting a conventional manual mode to operate the flood gate to be opened and closed in the interval during the power supply cutoff can be met.

Description

technical field [0001] The invention relates to the field of side-opening and vertical-rotating protection doors, in particular to a hydraulic side-opening and vertical-rotating protective airtight and anti-flooding door installed in the main line section of a subway. Background technique [0002] According to the relevant regulations of my country's "Civil Air Defense Law", the construction of subway projects must take into account the needs of civil air defense during wartime, and according to the requirements of "Code for Design of Metro" and "Code for Design of Civil Air Defense for Rail Transit Engineering", the construction of subway projects must be carried out for rivers or lakes. For subway projects in water areas, protective airtight and flood-proof doors should be installed at appropriate positions at both ends of the water area, or other flood-proof measures should be taken. As a kind of disaster prevention equipment, the anti-flooding door system is an effective ...

AI Technical Summary

Problems solved by technology

[0003] Existing anti-flood doors in subway sections mainly include three types of structures: flat-opening and vertical-rotating, lift-type and flat-push. Among them, the lift-type anti-flood doors require an equipment room larger than the size of the door opening, and the headroom of the machine room is relatively high. When the gate is closed manually in an emergency, the unlocking is complicated, and the gate falls without cushioning, which is easy to damage the track and ballast bed, resulting in increased maintenance costs; the driving methods of the commonly used flat-opening and vertical-rotating anti-flooding doors mainly include manual opening, Motor drive or hydraulic drive, in which manual opening is time-consuming and laborious, and it is extremely dangerous to operate the equipment under high water head pressure. The main disadvantage of the motor drive is that the system's waterproof treatment is relatively complicated, and its reliability in the flooded state There is no guarantee, relatively speaking, hydraulic drive is the most scientific way, but the use of hydraulic drive also has risks such as power supply cutoff, mechanical failure of the pump station, etc., which will affect the opening and closing of the anti-flooding door
