The bottom surface of the limiting tube 8 is flush with the support ring 52. A plurality of guide rods 81 are connected to the bottom surface of the limiting tube 8. The plurality of guide rods 81 are evenly distributed along the circumference of the limiting tube 8, and the bottom ends of the guide rods 81 are connected to the top surface of the support ring 52. An annular floating plate 82 is sleeved on the outer circumference of the mounting tube 51, and all guide rods 81 pass through the annular floating plate 82. An elastic folding tube 83 is connected to the bottom surface of the annular floating plate 82. The elastic folding tube 83 is sleeved outside all guide rods 81, and the bottom end of the elastic folding tube 83 is connected to the outer circumference of the support ring 52. When the annular floating plate 82 floats, the annular floating plate 82 is located below the liquid level. A plurality of drainage holes 511 are provided on the portion of the mounting tube 51 located above the support ring 52.

[0039] When the rainwater gradually submerges the annular floating plate 82, the annular floating plate 82 rises until the annular floating plate 82 contacts the bottom surface of the limiting tube 8. At this time, the elastic folding tube 83 blocks the rainwater, and the rainwater gradually overflows the filter screen 54. At this time, the rainwater falls into the installation tube 51 from the filter holes of the filter screen 54; when the liquid level of the rainwater drops, the annular floating plate 82 also gradually drops. At this time, the rainwater can flow into the outer peripheral surface of the installation tube 51 through the annular floating plate 82 and the limiting tube 8, and then enter the installation tube 51 through the drainage hole 511; the installation tube 51, the guide rod 81 and the annular floating plate 82 are used to limit debris in the drainage channel 2 to prevent debris from directly entering the water collecting tank 4, and the debris in the drainage channel 2 is also easy to clean.

[0040] A liquid level transmitter is installed on the top inner wall of the water collecting tank 4 adjacent to the water collecting tank 4 at the basement entrance. The liquid level sensor 9 is used to monitor the liquid level changes in the water collecting tank 4. The liquid level sensor 9 transmits the liquid level information to the terminal, and the terminal controls the water pump 43 to pump water.

[0041] The drainage method of urban civil air defense buildings includes the following steps: S1. Rainwater enters the drain 2 through the grille 21, and the filtering mechanism 5 filters the debris in the rainwater; S2. The filtered rainwater enters the installation pipe 51, and then enters the water collection tank 4; S3. The liquid level sensor 9 in the water collecting tank 4 monitors the liquid level change in the water collecting tank 4 and transmits the signal to the terminal; S4. When the liquid level reaches the height of the water collecting tank 41 / 5, start the entire basement 1 / 4 water pump 43, and give priority to starting the water pump 43 near the basement entrance; S5. When the liquid level reaches the height of the water collecting tank 42 / 5, start the entire basement 2 / 4 water pump 43, and give priority to starting the water pump 43 near the basement entrance; S6. When the liquid level reaches the height of the water collecting tank 43 / 5, start the water pump 43 of the entire basement 3 / 4, and give priority to starting the water pump 43 near the basement entrance; S7. When the liquid level reaches the height of the water collecting tank 44 / 5, start the entire basement water pump 43.

[0042] The implementation principle of the drainage device and method for urban civil air defense buildings in the embodiment of the present application is as follows: when a large amount of rainwater flows into the basement entrance, the rainwater flows from the basement ground to the drainage channel 2 at the entrance. At this time, part of the rainwater flows along the drainage channel 2 to the deep drainage channel 2, and the other part of the rainwater flows from the drainage pipe 22 of the drainage channel 2 to the water collecting tank 4. When the rainwater flows into the drainage pipe 22 through the installation pipe 51, larger debris such as leaves and packaging bags in the rainwater are filtered by the filter plate 53, and blocks such as sand and gravel in the rainwater are filtered by the filter screen 54. After filtering, the rainwater in the water collecting tank 4 flows to the deep water collecting tank 4 through the connecting pipe 3; at this time, the water pump 43 in the water collecting tank 4 is started, and the water pump 43 pumps out the rainwater in the water collecting tank 4, and discharges it to the outside of the basement through the pumping pipe 431, and the rainwater that quickly flows into the entrance of the basement is diverted, with one part flowing to the deep from the drainage ditch 2, and the other part being discharged to the deep from the connecting pipe 3, thereby speeding up the discharge of rainwater that flows into the entrance of the basement, reducing the occurrence of rainwater overflowing outside the drainage ditch 2, and avoiding damage to vehicles, objects, equipment, etc. caused by rainwater.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
