Through the setting of the mute cotton 603, the overall sound insulation effect can be further improved, and the setting of the diamond net rack 602 can achieve the purpose of energy absorption when impacted.
[0036] Please refer to Figure 1 , Figure 2 and Figure 3The indoor surface of the main body 1 is fixedly connected with a rectangular spray ring 8, and a group of nozzles 9 are fixedly connected to the peripheral surface of the rectangular spray ring 8. Through the above arrangement, the dust falling purpose can be achieved, and the external dust can be prevented from escaping into the indoor. The indoor surface of the main body 1 is fixedly installed with a temperature sensor 10. Through the above arrangement, the temperature of the main body 1 can be monitored in real time, and the temperature of the main body 1 caused by external fire can be prevented from being too high. The indoor surface of the main body 1 is installed with a dust concentration sensor 11. Through the above arrangement, the dust concentration near the main body 1 can be monitored in real time, and the external dust entering the indoor can be prevented.
[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 The outer surface of the rectangular spray ring 8 is fixedly connected with a connecting pipe 12, and the other end of the connecting pipe 12 is fixedly connected with the pump body in the external environment.

Through the above arrangement, the automatic control can be achieved, and the pump body can be controlled according to the real-time monitoring data.
[0038] The sound insulation civil defense door in the embodiment can effectively enhance the sound insulation performance of the door body while ensuring the overall mechanical strength by arranging the cavity 2 in the main body 1 and fixedly connecting the rubber pad 3 and the reinforcing rib 4 between the front and rear inner side walls of the cavity 2. The sound insulation board 5 arranged on the outdoor surface and the four-pyramid 7, the connecting plate 601, the rhombic grid 602 and the mute cotton 603 in the buffer assembly 6 can further scatter and absorb sound waves, greatly improve the sound insulation effect, and the rhombic grid 602 is made of elastic metal material and can be compressed when impacted, thereby playing an energy absorption role and effectively preventing the door body from deforming, so as to maintain good sealing performance.

[0039] The working principle of the above embodiment is that the sound wave first contacts the sound insulation plate 5 on the outdoor side of the civil air defense door, and the four-pyramid 7 structure arranged thereon reflects the sound wave in multiple directions, effectively reducing its penetration power, and initially achieving the sound insulation effect. After the sound wave is reflected by the four-pyramid 7, it continues to encounter the blockage of the sound insulation plate 5 body. The sound insulation plate 5 is dense in material and can effectively absorb part of the sound wave. Then, the sound wave penetrates the sound insulation plate 5 and enters the cavity 2 inside the main body 1. The rubber pad 3 between the front and rear inner side walls of the cavity 2 blocks the sound wave again, further consumes the sound wave energy by using its elastic and dense properties, and the elastic metal material properties of the diamond-shaped grid 602 can effectively absorb energy when subjected to external impact, prevent the door body from deforming, and maintain the sealing property. The rectangular spray ring 8 and the nozzle 9 provided on the indoor side of the main body 1 are connected to the pump body to provide stable water flow or air flow, thereby achieving the dust reduction function. At the same time, the temperature sensor 10 and the dust concentration sensor 11 monitor the environment in real time, and the data is fed back to the control host 13 to automatically control the pump body. When the dust in the external environment tries to enter the indoor environment, the rectangular spray ring 8 and the nozzle 9 fixedly connected to the indoor side of the main body 1 will start the dust reduction function, and the nozzle 9 can spray stable water flow or air flow to adsorb and settle the dust particles, thereby preventing the dust carrying radioactive substances from entering the indoor environment.
