[0002] As vital facilities for protecting people's lives and property, the sealing performance of the protective doors in civil defense projects is of paramount importance. Good sealing performance not only effectively resists the intrusion of harmful substances such as external shock waves, toxic agents, and radioactive dust, but also prevents the spread of smoke and heat during disasters such as fires, providing a safe refuge space for personnel. Before the protective doors of a civil defense project are put into use, their sealing performance needs to be tested using sealing performance testing equipment.

[0003] Since the testing frame of some testing equipment cannot be adjusted according to the different sizes of protective doors, the testing equipment can only be used to test protective doors of a certain size, which narrows the scope of application of the equipment. In view of the above reasons, this application proposes a rapid testing device for the sealing performance of protective doors in civil defense projects. Utility Model Content

[0039] Example

[0040] like Figure 1-5 As shown, this utility model proposes a rapid testing device for the sealing performance of a civil defense engineering protective door, including two horizontal frames 1 and an air pump 9 for inflation. The back of the horizontal frame 1 is provided with a sliding groove 2 for limiting the position. Two adjustment structures 3 for adjusting the size are provided between the two horizontal frames 1. The front of the two adjustment structures 3 and the two horizontal frames 1 are provided with two sealing strips 4 for forming a testing space. The exhaust end of the air pump 9 is provided with a three-way pipe 7 and a connecting pipe. The end of the connecting pipe away from the air pump 9 is provided with a pressure regulating valve 8. The other end of the pressure regulating valve 8 is provided with an installation pipe. The other end of the installation pipe is fixedly connected to one end of the three-way pipe 7. Both sides of the air pump 9 are provided with mounting plates. The top of the two mounting plates is provided with a PLC 11, an alarm light 12, and a display screen 10, respectively. The display screen 10 is used to display the pressure value in the testing space, the testing results, and related prompts in real time. The branch pipe of the three-way pipe 7 is provided with an exhaust hose 6. The exhaust hose 6 can introduce gas into the sealed space formed when the two sealing strips 4 are tightly fitted with the protective door.

[0041] The adjustment structure 3 includes a first vertical rod 301 and a second vertical rod 302. Two pressure sensors 5 are provided on the front of each of the two horizontal frames 1. These pressure sensors 5 can monitor pressure changes in the detection space in real time. Multiple pressure sensors 5 are located between two sealing strips 4. A connecting block 303 is fixedly installed at the far end of each of the two vertical rods 301 and 302. A positioning screw 304 is movably installed on each of the two connecting blocks 303. A slider 305 is fixedly installed on the back of the connecting block 303, and the slider 305 is movably connected to the sliding groove 2. The first vertical rod 301 and the second vertical rod 302 are movably connected to the two horizontal frames 1 respectively. The bottom and front of the first vertical rod 301 are respectively provided with a mounting cavity 1 and a groove 307. Multiple rectangular grooves 306 are provided on one inner wall of the mounting cavity 1. A receiving hole 309 is provided on one side of the vertical plate 308, and a positioning block 311 is movably installed within the receiving hole 309. A spring 310 is fixedly installed inside the receiving hole 309. One side of the positioning block 311 is fixedly connected to one end of the spring 310. The positioning block 311 is adapted to the rectangular groove 306. A vertical plate 308 for positioning is movably installed inside the mounting cavity 1. The top of the vertical rod 302 is provided with a mounting cavity 312 for installation. A telescopic plate 314 for filling the groove 307 is movably installed inside the mounting cavity 312. When adjusting the extension length of the vertical rod 301, the top of the telescopic plate 314 can automatically fit against the top inner wall of the groove 307, so that the groove 307 is always in a filled state, ensuring the sealing performance of the sealing strip 4 at this position. Limiting grooves are provided on both sides of the inner wall of the mounting cavity 312. Limiting blocks are fixedly installed on both sides of the telescopic plate 314. The limiting blocks and the limiting grooves are movably connected. Two springs 313 are fixedly installed at the bottom of the telescopic plate 314. The other end of the springs 313 is fixedly connected to the bottom inner wall of the mounting cavity 312.

[0042] In this embodiment, the dimensions of the equipment are first adjusted according to the size of the protective door. Multiple positioning screws 304 are rotated counterclockwise to separate one end from the horizontal frame 1. Then, two vertical rods 301 and 302 are pulled to adjust the frame width. After adjustment, the positioning screws 304 are rotated clockwise to make one end fit against the horizontal frame 1, thus positioning the vertical rods 301 and 302. When the frame height needs adjustment, the two positioning blocks 311 are simultaneously pressed inwards, compressing the spring 310. When the positioning block 311 is fully retracted into the receiving hole 309, the vertical rod 301 can be pulled up or down to change the overall height of the frame. When the positioning block 311 moves to the position of the rectangular groove 306, the spring 310 causes the positioning block 311 to reset and spring back from the rectangular groove 306. The system positions the vertical rod 301. During the movement of the vertical rod 301, the top of the telescopic plate 314 remains in contact with the inner top wall of the groove 307, moving with the vertical rod 301. After the size adjustment is completed, two matching sealing strips 4 are installed on the front of the frame using adhesive. Then, the detection frame is attached to the protective door, and the two sealing strips 4 are tightly attached to the protective door to form a relatively sealed detection space. Then, the air pump 9 is started to inflate the detection space until the pressure in the detection space reaches the set value. The pressure sensor 5 converts the real-time pressure signal into an electrical signal and transmits it to the PLC 11, which displays it on the display screen 10. If the pressure drop in the detection space exceeds the preset threshold within the set time, the sealing performance of the protective door is deemed unqualified, and the PLC 11 activates the alarm light 12; otherwise, it is deemed qualified.

[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
