[0038] Next, refer to Figures 1 - 3A civil air defense drainage device is described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the utility model.

[0039] As Figures 1 - 3 shown, a civil air defense drainage device includes a sump 100, a debris removal mechanism, and a pumping mechanism.

[0040] Among them, a cover plate 110 is provided at the top of the sump 100, and a long strip-shaped water inlet 120 is provided on the cover plate 110; the debris removal mechanism is arranged below the cover plate 110 and includes a motor 130 and a material pushing rod 140. The material pushing rod 140 is arranged corresponding to the water inlet 120, and the motor 130 is used to drive the material pushing rod 140 to swing to push the debris out of the water inlet 120; the pumping mechanism is arranged in the sump 100 and includes a water pump 150 and a drainage pipe 160. The water pump 150 is connected to the drainage pipe 160. When it rains, the accumulated water enters the sump 100 from the water inlet 120 on the cover plate 110, and the pumping mechanism drains the water from the drainage pipe 160 through the water pump 150. When the debris accumulates and blocks the water inlet 120, the debris removal mechanism is started, and the motor 130 drives the material pushing rod 140 to swing to push the debris out of the water inlet 120, so that the accumulated water can enter again from the water inlet 120.

[0041] Specifically, the sump 100 is a cube, and the cover plate 110 is square. Such a setting is easy for construction and is conducive to the setting of the long strip-shaped water inlet 120. As Figure 3 shown, a plurality of water inlets 120 are provided, and the plurality of water inlets 120 are arranged in parallel on the cover plate 110. Providing a plurality of water inlets 120 on the cover plate 110 is conducive to the entry of accumulated water and improves the drainage efficiency. Correspondingly, there are multiple material pushing rods 140, and the multiple material pushing rods 140 are parallel to the output shaft of the motor 130. Such a setting enables the motor 130 to drive the multiple material pushing rods 140 to push the debris at the multiple water inlets 120 outwards.

[0042] As Figure 1 shown, an installation cavity 170 is provided on the inner side surface of the sump 100, and the motor 130 is arranged in the installation cavity 170. The provision of the installation cavity 170 provides a space for installing the motor 130 and is conducive to the installation of the motor 130. Moreover, a waterproof cover 180 is provided at the opening of the installation cavity 170, and the waterproof cover 180 is provided with an output hole for accommodating the output shaft of the motor 130. The provision of the waterproof cover 180 for the installation cavity 170 plays a sealing role to prevent accumulated water from entering the motor 130. In addition, a sealing bearing 190 is provided in the output hole. The provision of the sealing bearing 190 in the output hole plays a sealing role to prevent accumulated water from entering the motor 130.

[0043] It should be noted that a stepped opening 200 is provided at the top of the sump 100, and the cover plate 110 is installed in the stepped opening 200. The provision of the stepped opening 200 at the top of the sump 100 is conducive to the installation of the cover plate 110.

[0044] It can be understood that the water pump 150 is arranged at the bottom of the sump 100. Arranging the water pump 150 at the bottom of the sump 100 is conducive to pumping water. Moreover, a filter screen 210 is provided above the water pump 150. The provision of the filter screen 210 above the water pump 150 can prevent sundries from entering the water pump 150.

[0045] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
