[0002] The sealing test of civil air defense projects is an important part of ensuring that civil air defense projects can effectively play a protective role in wartime. It mainly tests whether the sealing of the enclosure structure, protective closed doors, closed doors and other parts of the civil air defense projects meet the design requirements and relevant standards, so as to prevent toxic and harmful gases, radioactive substances and shock waves from the outside world from entering the interior of the civil air defense projects during wartime, and ensure the safety of sheltered personnel and materials.

[0003] When installing civil air defense pipes that pass through walls, rubber rings or sealing gaskets are usually used to improve the sealing between the pipes and the wall. However, when the sealing between the pipes and the wall needs to be tested, the connection point between the pipes and the wall needs to be soaked in water to check the water blocking effect, which is very inconvenient to operate. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present utility model is to provide a sealing detection device for civil air defense projects.

[0005] To achieve the above-mentioned purpose, the utility model proposes a sealing detection device for civil air defense projects, comprising a mobile lifting base, a lower shell being slidably arranged on the mobile lifting base, a lifting assembly being provided on the lower shell, an upper shell being installed on the lifting assembly, and rubber strips being fixedly connected to one side of the lower shell. A water tank is provided in the mobile lifting base, a water pump is installed in the water tank, and a hose is connected between the upper shell and the water pump.

[0006] In one example, the lower shell has the same shape as the upper shell, one side of the upper shell is fixedly connected to the upper arc plate, one side of the lower shell is fixedly connected to the lower arc plate, and the inner sides of the upper arc plate and the lower arc plate are fixedly connected to the elastic rubber pad.

[0007] In one example, the lower shell and the sides of the lower arc plate are both provided with communicating card slots, and the sides of the upper shell and the upper arc plate are both fixedly connected to rubber card strips, and the rubber card strips cooperate with the card slots.

[0008] In one example, two sliding grooves are provided on the upper surface of the movable lifting base, and sliding seats are slidably connected in the sliding grooves. A spring is fixedly connected between the sliding seat and the side wall of the sliding groove. The upper surfaces of the two sliding seats are fixedly connected to a fixed block, and the upper surface of the fixed block is fixedly connected to two vertical plates, and the two vertical plates are fixedly connected to the lower shell.

[0009] In one example, the lifting assembly includes a fixed plate, which is fixedly connected to the lower shell, a bracket fixedly connected to the fixed plate, a threaded rod threaded on the bracket, the threaded rod is rotatably connected to the upper shell, the threaded rod passes through the bracket, one side of the lower shell is fixedly connected to the support plate, a vertical rod is fixedly connected to the fixed plate, the vertical rod is slidably connected to the support plate, and the vertical rod passes through the support plate.

[0010] In one example, the outer sides of the two vertical plates are fixedly connected to an arc-shaped support plate, the arc-shaped support plate is located below the lower shell, the vertical plate passes through the arc-shaped support plate, the size of the arc-shaped support plate is larger than the lower shell, and one side of the arc-shaped support plate is flush with one side of the lower shell.

[0012] In one example, a counterweight is fixedly connected to the movable lifting base.

[0013] The civil air defense engineering sealing detection device proposed by the utility model can bring the following beneficial effects:

[0014] Firstly, by setting an upper shell and a lower shell, the upper shell rises and is spaced apart from the lower shell, and then the device moves horizontally so that the lower shell and the upper shell are located on the upper and lower sides of the civil air defense pipe, the lower shell rises, and the civil air defense pipe enters the lower shell, and the lifting assembly drives the upper shell to descend so that the upper shell fits with the lower shell, and the upper arc plate fits with the lower arc plate, and the civil air defense pipe is covered inside, so that the rubber strips on one side of the upper shell and the lower shell are against the wall, and water is filled between the upper shell and the lower shell through a water pump. Due to the action of the rubber strips, rubber card strips and rubber pads, the gap is reduced, and the speed of water overflow is reduced, so that water can fill the space between the upper shell and the lower shell, and the wall and the pipe are soaked at this time. The staff only needs to observe the overflow of water through the wall on the other side of the wall. The operation is convenient and the completed civil air defense pipe project can be inspected at any time, with less water consumption and water conservation.

[0015] Secondly, by setting up an arc-shaped support plate, the space between the upper shell and the lower shell is filled with water. At this time, water overflows from the gap between the upper shell and the lower shell, as well as from the gap between the upper shell, the lower shell and the wall. The water overflowing from the gap between the upper shell and the lower shell falls into the arc-shaped support plate below, and the water flowing out along the wall is blocked by the arc-shaped rubber block on one side of the arc-shaped support plate, so that part of the water enters the arc-shaped support plate for collection, saving water resources. The recovered water enters the water tank through the delivery pipe to replenish the water tank, which is convenient for recycling. BRIEF DESCRIPTION OF THE DRAWINGS
