[0021] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0022] It should be noted that the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by the skilled person in the field to which the present application belongs, unless otherwise stated.

[0023] As Figures 1-2 shown, the present embodiment provides a civil air defense door capable of detecting water level outside the door. The civil air defense door needs to separate the inside and outside of the civil air defense project, so that the person entering the civil air defense project can be protected. The civil air defense door needs to be strong enough, which makes the civil air defense door itself relatively thick and heavy, and does not have the condition to open a window. The civil air defense door capable of detecting water level outside the door provided by the present embodiment includes a door body 100, a display column 200 and a dredging piece. The display column 200 is vertically fixed to the inner side of the door body 100. A passage is constructed in the display column 200. The display column 200 has an indication window 221 extending along the length direction of the display column 200. The door body 100 is provided with a first communication hole 110 corresponding to the bottom end of the display column 200 and a second communication hole 120 corresponding to the top end of the display column 200. Although the door body 100 of the civil air defense door does not have the condition to open a window, a communication hole with a relatively small size can be opened. Both of the two communication holes are connected with the display column 200, so that the inside and outside of the door body 100 are still sealed and not connected, and there is no leakage. The dredging piece is arranged in the passage of the display column 200 to remove the blockage in the first communication hole 110. When there are sundries in the accumulated water, these sundries may enter the first communication hole 110. The sundries in the first communication hole 110 are poked apart or discharged by the dredging piece, which can ensure that the display column 200 is connected with the outside of the door body 100 through the first communication hole 110.

[0024] The display column 200 is connected with the outside of the door body 100. In the case of accumulated water, the specific water level of the accumulated water can be directly grasped through the display column 200 in the door body 100, which lays a foundation for subsequent safe operation.

[0025] In some embodiments, the display column 200 includes a transparent inner tube 210 and a protective outer tube 220. Since the transparent material is mostly glass or plastic such as acrylic, it has the disadvantages of being easy to break or easy to deform. In order to enhance the service life of the display column 200, the protective outer tube 220 is wrapped outside the transparent inner tube 210, and the indication window 221 is a strip-shaped hole opened on the protective outer tube 220. The transparent inner tube 210 can directly observe the water level, and the protective outer tube 220 arranged can protect the transparent inner tube 210 from being damaged by external force. The protective outer tube 220 can be made of metal material, which has better protection capability.

[0026] In some embodiments, the unclogging member comprises a rod 300 slidingly arranged at the bottom end of the display column 200, the rod 300 extending through both sides of the display column 200 and towards the first communication hole 110, a cleaning block 310 arranged at the end of the rod 300 away from the display column 200, and an operating handle 320 arranged at the end of the rod 300 close to the display column 200. The rod 300 is pulled by the operating handle 320, so that the cleaning block 310 at the front end of the rod 300 can push or poke apart the blockage, ensuring that the water outside the door body 100 can enter the display column 200 through the first communication hole 110. In order to facilitate the linear sliding of the rod 300, a bracket is further arranged in the first communication hole 110, the bracket comprising a circular ring 500 through which the rod 300 passes, and a connecting rib 510 arranged between the outer periphery of the circular ring 500 and the inner wall of the first communication hole 110.

[0027] In some embodiments, a limiting seat 400 is arranged at the position of the display column 200 corresponding to the position where the rod 300 passes through, the limiting seat 400 being internally configured with a sliding channel through which the rod 300 passes, and a protective cover 410 being further arranged on the limiting seat 400 to cover the operating handle 320. The sliding channel is internally provided with a sliding sealing structure, and the rod 300 and the limiting seat 400 are in sliding cooperation. The protective cover 410 covers the operating handle 320 when the unclogging member is not needed, which can prevent accidental touch and protect the operating handle 320.

[0028] In some embodiments, the display column 200 is provided with a letting-in hole at the position corresponding to the position where the rod 300 passes through, and a sliding sealing member is arranged in the letting-in hole. The sliding sealing member can ensure that the inside of the display column 200 is always in a sealed state with the space inside the door body 100, avoiding water from the display column 200 entering the space inside the door body 100.

[0029] In some embodiments, the cleaning block 310 is a disc, and the diameter of the disc is 1 / 4-1 / 2 of the diameter of the first communication hole 110.

[0030] In some embodiments, the cleaning block 310 comprises a plurality of radially distributed supporting rods, each of which extends radially outwardly along the rod 300.

[0031] In some embodiments, the door body 100 is further provided with a filter cover 111 corresponding to the first communication hole 110, and the filter cover 111 is detachable along the axial direction of the first communication hole 110. The filter cover 111 is semicircular or conical. The inner edge of the buckle end of the filter cover 111 is provided with a buckle groove, and the position of the first communication hole 110 is provided with a convex edge matched with the buckle groove. When the debris is large and just blocks the outside of the filter cover 111, the rod body 300 cannot ensure that the water enters the display column 200 during the insertion and extraction in the first communication hole 110. Therefore, the rod body 300 needs to be stretched out of the outside of the first communication hole 110, the filter cover 111 is pushed away, and then the first communication hole 110 is dredged. After the danger is discharged, the door body 100 can be opened, and the filter cover 111 is reassembled outside the first communication hole 110.

[0032] In the description of the present application, it should be understood that the terms in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. In the description of the present application, the meaning of "a plurality of" is more than two, unless otherwise specifically limited.
