[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-7 As shown, a drainage device for civil air defense doors comprises a civil air defense door body 1, a back plate 2 is installed on the civil air defense door body 1, a water diversion hood 3 is installed on the back plate 2 through a fixed structure 7, a steel pipe 4 is plugged into the water diversion hood 3, three clamps 5 are installed on the civil air defense door body 1, the inner wall of the clamp 5 is in conflict with the steel pipe 4, the top of the steel pipe 4 is fixedly connected with a bellows 6, a rotating sleeve 9 is installed on the civil air defense door body 1, the steel pipe 4 is installed on one end of the water diversion hood 3 facing the rotating sleeve 9, the water diversion hood 3 and the steel pipe 4 are perpendicular to each other, and the end of the bellows 6 is connected to an external water pump; by installing the drainage device on the civil air defense door body 1, the flexibility of use of the civil air defense door body 1 is improved, and the poor indoor air circulation is avoided to affect the living environment.
[0024] As a technical optimization solution of the present invention, the water diversion hood 3 is a triangular structure, and a plurality of through holes 8 are equidistantly provided on the water diversion hood 3; the triangular structure of the water diversion hood 3 is conducive to reducing material waste and saving production costs. At the same time, the water diversion hood 3 is provided with a plurality of through holes 8 so that the water diversion hood 3 can play a filtering function.
[0025] As a technical optimization solution of the present invention, the fixing structure 7 includes a card slot 701, a card slot 701 is opened on the back plate 2, and a card strip 702 is fixedly connected to the water diversion cover 3, and the card strip 702 is engaged in the card slot 701; the card strip 702 drives the water diversion cover 3 to be quickly installed on the back plate 2, thereby improving the installation efficiency of the water diversion cover 3.
[0026] As a technical optimization solution of the present invention, the cross section of the clamping groove 701 is a trapezoidal structure, and the cross section of the clamping strip 702 is a trapezoidal structure; thus, the stability of the installation of the water guide cover 3 is increased.
[0027] As a technical optimization solution of the present invention, the back plate 2 is fixedly connected to one end of the rotating sleeve 9 with a baffle 703, and the end of the water guide cover 3 conflicts with the baffle 703 to prevent the card strip 702 from slipping off the other end of the card slot 701 during installation.
[0028] As a technical optimization solution of the present invention, a plurality of bolts 704 are rotatably connected to the water diversion hood 3, and the bolts 704 are rotatably connected to the back plate 2, and the ends of the bolts 704 are threadedly connected to the civil defense door body 1; the bolts 704 not only firmly install the back plate 2, but also have a positioning effect on the water diversion hood 3, preventing the clip 702 on the water diversion hood 3 from slipping out of the slot 701 and causing the water diversion hood 3 to fall off, thereby increasing the stability of the installation of the water diversion hood 3.
[0029] When the lock body 702 is in the unlock position, the lock body 702 is locked, and the lock body 703 is unlocked, so that the lock body 702 can be unlocked. Stability; then start the external water pump, and under the action of the water pump, the indoor floor water is continuously sucked into the water inlet cover 3. Since the water inlet cover 3 is arrayed with multiple through holes 8 with smaller diameters, the water inlet cover 3 can play a good filtering role, preventing some larger impurities from entering the steel pipe 4 with the water flow, causing the pipe to be blocked and affecting the use of the drainage equipment. When the filtered floor water enters the water inlet cover 3, the water flow is sucked into the steel pipe 4 and enters the bellows 6 through the steel pipe 4. The setting of the bellows 6 prevents the pipeline from hindering the rotation of the civil air defense door body 1, and then the water flow in the bellows 6 is discharged by the water pump, so that the floor water is discharged to the outside. By installing the drainage equipment on the civil air defense door body 1, when the flow rate of external water flowing into the room is not large, the indoor accumulated water can be discharged through the drainage equipment without closing the civil air defense door body 1, thereby improving the flexibility of the use of the civil air defense door body 1 and keeping the indoor air circulation unobstructed.
