Description

Technical Field

[0001] The present invention relates to the technical field of civil air defense door detection, in particular to a detection device for a civil air defense door. Background Art

[0002] Civil defense is also called civil defense. Civil defense doors belong to civil defense protection equipment. They are activities to take anti-air raid, disaster relief measures, implement rescue operations, prevent and reduce disaster hazards. They are mainly used in various openings of civil defense projects to block shock waves, chemical agents, electromagnetic pulses, shrapnel, and early nuclear radiation. They must meet the requirements of protection and sealing functions. Therefore, airtightness testing is an important indicator for evaluating the performance of civil defense doors.

[0003] Most of the existing civil air defense sealed door inspections use the water immersion method, which detects bubbles, resulting in a large waste of water resources. The civil air defense doors need to be dried after inspection, and when limiting the door leaves, only door leaves of a single size can be sealed, and cannot be adapted to door leaves of multiple sizes. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a detection device for a civil air defense door, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a detection device for civil air defense doors, comprising a detection platform, the surface of the detection platform is provided with an embedded groove for placing a door leaf, the inner cavity of the embedded groove is provided with a support frame arranged below the detection platform, the detection platform is a sealed cavity, and the inner cavity of the detection platform is connected with an air blowing pipe located below the support frame, the surfaces of the detection platform located on the upper and lower sides of the embedded groove are slidably connected with sliding plates driven by a driving cylinder, one side of the two sliding plates is fixedly connected with an elastic airbag, and the opposite sides of the two elastic airbags are fixedly connected with a clamping plate for clamping the door leaf up and down;

[0006] The surfaces of the detection platform on the left and right sides of the embedded groove are fixedly connected with pneumatic rods connected with the elastic airbags through air intake pipes, the piston end of the pneumatic rod is fixedly connected with a sliding cylinder slidably connected to the surface of the detection platform, both ends of the sliding cylinder are connected with top plates through sliding rods, the two top plates are respectively abutted against the side edges of the two clamping plates, the side edges of the sliding cylinder are fixedly connected with extrusion airbags, the two sides of the extrusion airbags are fixedly connected with telescopic airbags, the two telescopic airbags are respectively fixedly connected with the side edges of the two top plates, when in use, the door leaf is placed in the embedded groove, and then the cylinder is driven to drive the sliding plate to move, and the sliding plates on both sides drive the clamping plates to move to squeeze the side edges of the door leaf, At this time, the elastic airbag is compressed, and the internal gas enters the pneumatic rod through the air intake pipe, pushing the sliding cylinder to move toward both sides of the door leaf. At this time, the clamping plate squeezes the two top plates to compress the telescopic airbag, and then the telescopic airbag and the extrusion airbag are squeezed on the side of the door leaf to seal the four sides of the door leaf. Then a sealed space is formed in the inner cavity of the test bench, and colored eye-catching gas is injected into the embedded groove through the blowing pipe. Then, the sealing state is judged by observing whether there is gas escaping in the gap between the door leaf and the door panel. The sealing test of door leaves of different widths can be carried out with strong adaptability. Moreover, through the setting of multiple airbags, the air pressure can be automatically balanced, and the extrusion force on the side of the door leaf can be adjusted to make the covering tighter.

[0007] As a further solution of the present invention: the opposite sides of the two clamping plates are coated with rubber strips, and the rubber strips are squeezed between the clamping plates and the door leaf to seal the gap between the clamping plates and the door leaf, and to seal the upper and lower sides of the door leaf.

[0008] As a further solution of the present invention: a limit stopper is fixedly connected to one side of the clamping plate toward the sliding plate. By setting the limit stopper, the distance between the sliding plate and the clamping plate can be limited to prevent the elastic airbag from being damaged due to excessive squeezing.

[0009] As a further solution of the present invention: the upper and lower clamping plates, the left and right telescopic airbags and the internal partitions of the squeezing airbags above and below the telescopic airbags form a rectangular cavity for sealing the door leaf.

[0010] As a further solution of the present invention: the bottoms of the telescopic airbag, the extrusion airbag and the clamping plate are connected to the surface of the test bench through elastic bands, and the gaps are sealed by the elastic bands, so that the sealing effect can be ensured even when the telescopic airbag, the extrusion airbag and the clamping plate move.

[0011] As a further solution of the present invention: a plurality of the air blowing pipes are provided and are evenly arranged in the gap of the supporting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: colored eye-catching gas is injected into the embedded groove through the blowing pipe, and then the sealing state is judged by observing whether there is gas escaping in the gap between the door leaf and the door panel. The sealing performance of door leaves of different widths can be detected, and the adaptability is strong. Moreover, through the setting of multiple air bags, the air pressure can be automatically balanced, and the squeezing force on the side of the door leaf can be adjusted, so that the covering is tighter.
