Description

Outdoor wind gap structure of underground garage Technical Field The utility model relates to the technical field of fresh air systems, in particular to an outdoor air port structure of an underground garage. Background The outdoor wind gap of underground garage is the key facility of building ventilation system, mainly used realizes the inside and outside air exchange of garage, ensure inside air quality up to standard and discharge harmful gas, its design adopts rain-proof tripe structure usually, and inclined blade can effectively block rainwater and debris entering, allows air free circulation simultaneously, and the wind gap material is mostly corrosion-resistant aluminum alloy or stainless steel, compromise intensity and durability, and partial high-end project still can install the amortization layer in the wind gap inside additional, reduces fan operational noise, and the mounted position selects more in garage side wall or disguise, both satisfies ventilation efficiency, does not influence the building outward appearance again, is the important link of underground space environment guarantee. The outdoor wind gap of traditional underground garage is normally open type structure of concrete material, when meetting the condition of a fire, the air that gets into from the wind gap can lead to the condition of a fire burning more violently, has great potential safety hazard. Disclosure of utility model The utility model aims to provide an outdoor air port structure of an underground garage, which aims to solve the problems that the traditional outdoor air port of the underground garage is usually of a normally open structure made of concrete materials and has larger potential safety hazard because air entering from the air port can cause the burning of the fire when encountering the fire. The outdoor air port structure of the underground garage comprises a main frame, wherein a shutter is arranged on the side wall of the main frame, a group of sealing plates are sequentially arranged on each side wall of the main frame from top to bottom on the inner side of the shutter, the upper ends of the sealing plates are rotatably connected with the main frame through rotating shafts, synchronous rods are arranged at the middle positions of the inner sides of each group of sealing plates, the outer sides of the synchronous rods are rotatably connected with the lower edges of the sealing plates through rotating shafts, connecting seats are arranged at the middle positions of the inner sides of the main frame, pull rods are rotatably connected between the connecting seats and the four synchronous rods through rotating shafts, a top plate is arranged at the upper end of the main frame, a magnetic breaker is arranged at the middle position of the lower surface of the top plate, and the middle positions of the upper surfaces of the connecting seats are connected with the lower ends of the magnetic breakers through cables. Preferably, a concrete base is arranged below the main frame, the main frame is propped against the concrete base, a ventilation shaft is arranged in the middle of the concrete base in a penetrating mode, and the ventilation shaft is connected with an inner cavity of the main frame in a communicating mode. Preferably, the side wall of the main frame is provided with a cross beam at the lower end of the shutter, the shutter is arranged on the cross beam, and the side wall of the main frame is provided with a fireproof plate at the lower end of the cross beam. Preferably, a top beam is arranged at the upper end of the main frame, the top plate is arranged on the top beam, and the upper end of the shutter is propped against the top beam. Preferably, the four pull rods are rotationally connected with the connecting seat to form a cross structure. Compared with the prior art, the utility model has the beneficial effects that the traditional normally open type structure of the underground garage outdoor air port made of concrete is replaced, the metal frame structure air port is arranged on the basis of concrete, the openable sealing plate structure is arranged in the air port, when a fire occurs, the sealing plate is closed under the action of self gravity to seal the air port, and the air entering from the air port is reduced, so that the fire is delayed, and certain potential safety hazard is avoided.
