Technical Field

[0001] The utility model relates to a rubber airbag pressure detection platform for an air shield dam, belonging to the technical field of inspection and testing of water conservancy and hydropower facilities. The rubber airbag pressure detection platform for an air shield dam is a device for inspecting and testing the pressure resistance and air tightness of the rubber airbag. Background Art

[0002] Dams are important facilities of modern water conservancy, and they play an important role and bring benefits to the national economy and people's livelihood. In particular, the current movable dam type air shield dam has been favored by industry insiders. The core technology and components of the air shield dam are rubber airbags. However, since the rubber airbags used in the air shield dam are large rubber products, although the preparation processes, technologies and production equipment are different, they all involve the inspection of the pressure resistance and air tightness of the rubber airbags. Generally, the inspection is carried out by using a simulation inspection platform with concrete and anchor bolts. The shortcomings are: 1) The size specifications of the rubber airbags are different, and the specifications of the anchor bolts used are different, so different simulation inspection platforms need to be prefabricated; 2) The anchor bolts used fail after several inspections; 3) This type of inspection platform is only suitable for the perforation anchoring method of small rubber airbags.
