[0002] With the development of economy and the progress of aviation industry technology, the number of aircraft in service as a means of transportation and military application platform has shown a blowout development in recent years, which has brought about a large demand for hangars for daily parking, maintenance and overhaul of aircraft. Driven by practical needs, both civil aviation airports and military airports are equipped with a large number of large-span steel structure hangars. Limited by technical conditions and construction costs, such large-span steel structure hangars usually adopt a doorless structure, that is, the front and rear ends of the hangar are open. Although the aircraft can be parked, overhauled and maintained in the hangar, it is difficult to avoid the erosion of the aircraft by harsh environments such as wind and sand. In addition, due to the doorless structure, the hangar interior is integrated with the outside world, resulting in the inability to freely control the hangar interior environment. The working environment of the maintenance and overhaul operators is poor, so the hangar door is needed for shielding. In the use of today's hangar doors, the sealing performance of the hangar doors is insufficient, resulting in dust intrusion and easy interference in bad weather, and vibration when the hangar door is sealed and closed, thereby damaging the sealing performance.

The pressure sensor 35 is connected to the controller through a wire, and the controller is connected to the electric telescopic rod 36 through a wire. The sealing tank body 1 is buried and installed in the ground. When the hangar door is closed, the bottom of the hangar door enters the sealing tank body 1. At this time, the electric telescopic rod 36 drives the fixing plate 34 to move to fix and seal the hangar door. The sealing gasket 37 seals the hangar door while protecting the hangar door to prevent the hangar door from directly contacting the fixing plate 34 and causing wear. When the hangar door enters the sealing tank body 1, the fixing block 32 is squeezed to shrink the compression spring 30.

The shock absorbing member 43 and the buffer sponge 42 buffer the hangar door to reduce the vibration force when the hangar door is closed. At the same time, the protective pad 40 protects the bottom of the hangar door to prevent the wear of the bottom of the hangar door from affecting the sealing performance.
