The hydraulic system of the horizontal opening and vertical rotating protective sealing and anti-flooding door

Abstract

The invention relates to a hydraulic system of a sliding vertical rotating type protection airtight and flooding preventing door. The hydraulic system comprises a pump station and a valve set, and the pump station and the valve set are in control connection with a pull rod oil cylinder, an engineering oil cylinder and a hydraulic motor on the sliding vertical rotating type protection airtight and flooding preventing door. The pump station comprises an oil tank, a manual pump, a motor, an oil pump, an oil suction filter and an oil return filter. The valve set comprises a first set of valves, a second set of valves and a third set of valves, and the first set of valves, the second set of valves and the third set of valves are connected in parallel. When water enters a subway tunnel, the sliding vertical rotating type protection airtight and flooding preventing door can be closed fast and safely. The pump station can be driven by electricity at ordinary times, and the sliding vertical rotating type protection airtight and flooding preventing door is operated. The advantage that when one pump station fails, the sliding vertical rotating type protection airtight and flooding preventing door can be normally opened is achieved. When electricity supply fails, the sliding vertical rotating type protection airtight and flooding preventing door can be opened and closed by operating the manual pump in a machine room, the sliding vertical rotating type protection airtight and flooding preventing door can also be opened and closed in a traditional manual mode in a section, and thus the operation is achieved.

Description

technical field [0001] The invention relates to a hydraulic system for a flat-opening and vertical-rotating protective door. 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 barrier to prevent river water from pouring into the subway station in the event of an accident in the tunnel.

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
