[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a protective sealing device for civil air defense equipment engineering provided by the utility model; Figure 2 for Figure 1 A rear view schematic diagram of a protective sealing device for civil air defense equipment engineering is shown; Figure 3 for Figure 1 The schematic diagram of the internal structure of the protective door shown; Figure 4 for Figure 1 The schematic diagram of the internal structure of the limiting block shown; Figure 5 for Figure 1 The A part is shown in the enlarged diagram Figure 1A protective sealing device for civil air defense equipment engineering includes: a protective door frame 1, a protective door 2 is hinged on the protective door frame 1, a movable sealing pad 1 3 is arranged on the protective door 2, a movable sealing pad 2 4 is arranged on the protective door 2, a fixed sealing pad 1 5 is arranged on the protective door frame 1, a fixed sealing pad 2 6 is arranged on the protective door frame 1, the movable sealing pad 1 3 is matched with the fixed sealing pad 1 5, the movable sealing pad 2 4 is matched with the fixed sealing pad 2 6, a closed cavity 7 is formed between the protective door frame 1 and the protective door 2, an inflation port 8 is opened on the inner wall of the top of the protective door frame 1, an inflation pump 9 is installed on the top of the protective door frame 1, and an air intake pipe 10 is fixedly connected to the inflation pump 9. The device forms a closed cavity 7 through double sealing and can be inflated to form an air pressure difference, which greatly enhances the barrier effect of external poisonous gas and provides reliable safety protection for internal personnel.

[0022] The protective door 2 is rotatably connected with a connecting rod 11, one end of the connecting rod 11 is fixedly connected with a turntable 12, and the other end of the connecting rod 11 is fixedly connected with a closing gear 13. A booster motor 14 is installed inside the protective door 2, and a booster gear 15 is fixedly connected to the driving end of the booster motor 14. The booster gear 15 is meshed with the closing gear 13. A closing plate 16 is slidably connected inside the protective door 2, and a plurality of straight

[0023] Teeth 17, a guide rail 18 is fixedly connected to the inside of the protective door 2, and a limiting slope 19 is opened on the right side of the closing plate 16. In order to form a closed closed chamber 7, the sealing gaskets must fit tightly, and the turntable 12 is turned to drive the closing gear 13 to rotate, and then the closing plate 16 moves to the right through the meshing straight teeth 17. Since the protective door 2 is generally bulky, at this time, the power-assisted motor 14 is started to drive the power-assisted gear 15 to rotate, and the meshing power-assisted closing gear 13 is rotated, so that the fitting of the sealing gasket on the overweight protective door 2 becomes easy and convenient, and the formation of the closed chamber 7 is also faster.

[0024] A limiting block 20 is fixedly connected to the protective door frame 1, and a closing groove 21 is opened inside the limiting block 20. The closing groove 21 is adapted to the limiting slope 19. A blocking rod 22 is fixedly connected inside the protective door 2. When the closing plate 16 slides to the right, the limiting slope 19 cooperates with the closing groove 21 to squeeze the protective door 2 into the protective door frame 1, so that the adapted sealing gasket fits more tightly and the airtightness of the closed cavity 7 is improved.

[0025] A control panel 23 is installed on the protective door frame 1 , an interactive screen 24 is installed on the control panel 23 , and an interactive button 25 is provided on the control panel 23 . The control panel 23 controls the start and stop of the air pump 9 and the power-assisting motor 14 .

[0026] A protective net 26 is fixedly connected to the protective door 2, and a detector 27 is installed inside the protective net 26. The detector 27 can detect the pressure, temperature, etc. outside the protective door 2. The electronically connected control panel 23 displays these data through the interactive screen 24, making it more intuitive for people inside the civil air defense equipment to observe.

[0027] An observation window 28 is installed on the protection door 2, and a plurality of mounting plates 29 are fixedly connected to the protection door frame 1. The protection door frame 1 is installed on the civil air defense equipment through the mounting plates 29.

[0028] The working principle of a protective sealing device for civil air defense equipment engineering provided by the utility model is as follows:

[0029] After closing the protective door 2, the matching movable sealing gasket 3 and the fixed sealing gasket 5 form a first airtight barrier, and the movable sealing gasket 2 4 and the fixed sealing gasket 2 6 form a second airtight barrier, so that a closed space is formed inside the civil defense equipment. When the external poisonous gas pressure is too high, the poisonous gas may still leak into the civil defense equipment. At this time, a closed cavity 7 is formed between the two closed barriers, and the air pump 9 inflates the closed cavity 7 through the inflation port 8. The air intake pipe 10 is connected to the interior of the civil defense equipment, so that high pressure is formed inside the closed cavity 7 to ensure the airtightness of the civil defense equipment even when the external air pressure is high.

[0030] Compared with the related art, the protective sealing device for civil air defense equipment engineering provided by the utility model has the following beneficial effects:

[0031] The device forms a closed chamber 7 through double sealing and can be inflated to form a pressure difference, which greatly enhances the barrier effect against external poisonous gas and provides reliable safety protection for internal personnel. When facing the threat of poisonous gas, even if the external pressure is large, it can effectively prevent the penetration of poisonous gas, ensure the safety of the internal environment of the civil air defense equipment, avoid personnel from being harmed, and build a solid line of defense for life safety. In addition, the addition of the electric power assist device makes it easy and convenient to fit the sealing gasket on the overweight protective door, which not only improves the closing efficiency, but also ensures that the protective action is completed quickly at the critical moment, and buys more safety time for personnel.
