Technical Field
[0001] The utility model relates to the field of products related to inflatable membrane buildings, in particular to an inflatable membrane building ventilation structure. Background Art
[0002] There are three types of inflatable membrane structures: single-layer, double-layer, and air-ribbed. Inflatable membrane structures generally require long-term uninterrupted energy supply. The single-layer inflatable membrane structure in low-arch and large-span buildings must be a closed space and maintain a certain indoor and outdoor air pressure difference. Inflatable structure, also known as "inflatable membrane structure", refers to the structure of a house formed by filling air into a film product made of polymer materials. Inflatable structure can be divided into air-supported membrane structure and air-expanding membrane structure. The most typical inflatable membrane structure building is the Water Cube.
[0003] However, the ventilation effect of the inflatable membrane buildings currently on the market, especially the ventilation devices of the polymer inflatable membrane buildings, is poor during use, which makes it difficult to maintain the internal and external air pressure of the inflatable membrane buildings at a normal level.

[0006] Preferably, the output end of the air pressure sensor is connected to the input end of the controller, and the output end of the controller is connected to the input end of the motor and the air pump.
[0007] Preferably, one side of the sealing plate is fixedly connected to a limiting rod, one end of the limiting rod extends into the pressure relief pipe and is fixedly connected to a cross-shaped positioning plate, and a sliding groove corresponding to the cross-shaped positioning plate is provided on the inner wall of the pressure relief pipe, and the four corners of the cross-shaped positioning plate are slidably inserted in the sliding groove.
[0008] Preferably, the motor is a servo motor.
[0009] Preferably, the sealing ring is made of rubber.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The inflatable membrane building ventilation structure starts the air pump and uses the delivery pipe to inflate the air cavity in the main body, monitors the pressure in the air cavity through the air pressure sensor in the air cavity, and sends a signal to the controller. When the pressure value is greater than the set value, the controller starts the motor, and the motor will drive the threaded rod to rotate. When the threaded rod rotates, the connecting sleeve on which the thread is sleeved will use the traction block to cause the sealing plate to move, thereby leaking out the pressure relief pipe to discharge the excess pressure. When the pressure reaches the set value, the motor is controlled to drive the threaded rod to reverse and seal the pressure relief pipe. The utility model adopts the setting of the pressure monitoring constant component to effectively enable the inflatable membrane to actively ventilate during use and maintain a stable air pressure.
