[0043] Reference Figures 7-11 The safety assembly 4 is used for providing an air pressure buffer area, and improving the safety of the civil air defense door door plate detection link. The safety assembly 4 comprises a safety shell 401 and a safety plate 406. The outer wall of the safety shell 401 is fixedly connected with the connecting block 15.

The clamp one 404 comprises a hydraulic cylinder arranged in the inside. The output end of the hydraulic cylinder is connected with a clamping jaw.

[0045] Supplementary explanation based on the above structure is as follows: in the process of supporting assembly 3 moving upward driven by clamp three 8, since clamp three 8 clamps third section 3043, when the upper end surface of bottom plate 301 coincides with the upper end surface of sealing plate two 18, third section 3043 is below sealing plate two 18, and the rest of supporting assembly 3 is above sealing plate two 18, at this time, start the hydraulic cylinder inside clamp one 404, clamp one 404 clamps second section 3042, realizing the clamping of safety assembly 4 to supporting assembly 3;

[0046] After safety assembly 4 clamps supporting assembly 3, clamp three 8 releases supporting assembly 3, at this time, supporting assembly 3 is completely clamped by safety assembly 4, start motor two 503, motor two 503 drives clamp one 404 to move, the moving principle is consistent with that of motor three 9 driving clamp three 8, clamp one 404 drives supporting assembly 3 to move upward, entering detection assembly 5;

[0047] When third section 3043 is above sealing plate two 18, start driver one 11, driver one 11 pushes the two safety plates 406 to move towards each other, so that safety plates 406 shield process hole two 21.

[0048] Reference Figures 11-15 Detection assembly 5 is used for detecting the overall shape, air tightness and the air pressure that can be borne of the door plate of the civil air defense door, detection assembly 5 includes detection shell 501, detection shell 501 is arranged above safety assembly 4, the lower end of detection shell 501 is fixedly connected with the upper end of safety shell 401, when a plurality of detection assemblies 5 are sequentially installed, the detection shells 501 of each group of detection assemblies 5 are fixedly connected with each other, limit holes two 508 are arranged on the peripheral shell walls of detection shell 501, sealing plate one 12 is fixedly installed at the bottom of detection shell 501, motor one 403 is fixedly installed at the lower end surface of sealing plate one 12, bulb 14 is installed at the bottom end of sealing plate one 12, process hole one 13 is arranged at the middle position of sealing plate one 12, long side baffle 506 and wide side baffle 507 are respectively arranged symmetrically above sealing plate one 12, sealing rings one are installed around long side baffle 506 and wide side baffle 507, long side baffle 506 is above wide side baffle 507, the width of wide side baffle 507 is consistent with the distance between the two baffles 306, the height of wide side baffle 507 is consistent with the height of baffle 306, driver two 20 is fixedly installed on the outer wall of detection shell 501 close to limit hole two 508, driver two 20 is the same as driver one 11 in structure, the output end of driver two 20 penetrates limit hole two 508 and is fixedly connected with the upper end of long side baffle 506 and wide side baffle 507 respectively;

[0049] The upper end of the sealing plate 12 is provided with a motor 503, the motor 503 is installed on the lower end surface of the sealing plate 12 of the upper detection assembly 5, the output end of the motor 503 faces the sealing plate 12, the output end of the motor 503 is connected with a screw rod 502, the screw rod 502 is threadedly connected with a ring 505, the ring 505 is connected with a clamp 504, the clamp 504 includes a hydraulic cylinder arranged inside, and the output end of the hydraulic cylinder is connected with a clamping jaw.

[0050] The supplementary explanation based on the above structure is as follows: in the process that the clamp 404 drives the support assembly 3 to enter the detection assembly 5 from the safety assembly 4, since the clamp 404 clamps the second section 3042, the first section 3041 first passes through the sealing plate 12 to enter the detection assembly 5, and when the first section 3041 is located inside the detection assembly 5, the clamp 504 clamps the first section 3041, and the clamping principle is consistent with that of the clamp 8;

[0051] When the clamp 504 completes clamping, the clamp 404 is controlled to release the support assembly 3, the motor 403 drives the clamp 404 to move downward until the clamp 404 moves to the position of the third section 3043, the clamp 404 clamps the third section 3043, at this time, the clamp 504 clamps the first section 3041 and the clamp 404 clamps the third section 3043, the motor 403 and the motor 503 are controlled to work synchronously, so that the clamp 404 and the clamp 504 cooperatively drive the support assembly 3 to move upward, and when the second section 3042 moves into the detection assembly 5, the motor 403 and the motor 503 are controlled to stop working;

[0052] The clamp 504 is controlled to release the support assembly 3, the motor 503 drives the clamp 504 to move to the position of the second section 3042, so that the clamp 504 clamps the second section 3042, the clamp 404 is controlled to release the support assembly 3, and the clamp 504 drives the support assembly 3 to move upward to enter the upper detection assembly 5, the transportation principle between the detection assemblies 5 of different layers is consistent with the above principle, and finally the bottom plate 301 is located at the same water position as the sealing plate 12 of the uppermost detection assembly 5, since the shape of the support assembly 3 is same as that of the process hole 13, the sealing ring 2 of the support assembly 3 seals the process hole 13 at this time, and the gas in the detection assembly 5 can only flow through the gap between the rollers 305;

[0053] The principle of moving the support assembly 3 downward to reset from the uppermost detection assembly 5 is consistent with the above principle, but the operation is opposite.

[0054] The three groups of detection assemblies 5 are arranged in an exemplary manner. The detection shells 501 of each group of detection assemblies 5 are fixedly connected. The lowermost detection shell 501 is fixedly installed above the safety shell 401. The outer walls of the safety shell 401 and the detection shell 501 are fixedly connected with the connecting block 15. The uppermost detection assembly 5 is fixedly installed above the top shell 19. The lower end of the top shell 19 is provided with the bulb 14. The air inlet cylinder 16 penetrates through the outer shell 1 and the top shell 19 and is in communication with the inside of the uppermost detection assembly 5. The outer shell 1 is provided with the compressor 17. The output end of the compressor 17 is connected with the pipeline of the air inlet cylinder 16.

[0055] In the case that the remaining conditions remain unchanged, the detection steps of the door panel of the civil defense door are as follows:

[0056] Step one: the civil defense door panel to be detected is transported to the upper side of the support assembly 3 through the track 2. The motor three 9 and the motor one 403 are started to drive the support assembly 3 into the safety assembly 4.

[0057] Step two: the motor one 403 and the motor two 503 are started to drive the support assembly 3 into the detection assembly 5. Each group of detection assemblies 5 cooperates with each other to make the support assembly 3 enter the uppermost detection assembly 5.

[0058] Step three: the overall shape and air tightness of the civil defense door panel are detected by the uppermost detection assembly 5.

[0059] Step four: the support assembly 3 is controlled to move so as to be located in the inside of the detection assembly 5 at different heights to detect the maximum air pressure that can be borne by the civil defense door panel.

[0060] Specifically, in step three, the driver two 20 of the uppermost detection assembly 5 is started. The driver two 20 pushes the long side baffle 506 and the wide side baffle 507 to move towards the civil defense door panel until the sealing ring one of the long side baffle 506 and the wide side baffle 507 is attached to the periphery of the civil defense door panel above the support assembly 3. The long side baffle 506 and the wide side baffle 507 push the civil defense door panel to adjust the position. Since the driver two 20 works uniformly, the civil defense door panel is finally located in the middle position of the support assembly 3. The long side baffle 506 and the wide side baffle 507 realize the position control of the civil defense door panel of different specifications. At this time, the wide side baffle 507 covers the rollers 305 of the wide side of the civil defense door panel. The long side baffle 506 covers the rollers 305 of the long side of the civil defense door panel. The light sensor 302 is shielded. The sealing ring one of the long side baffle 506 and the wide side baffle 507 is attached to the surface of the civil defense door panel to seal the periphery of the civil defense door panel.

[0061] Further, the compressor 17 delivers the rated amount of high pressure gas into the detection assembly 5 through the air inlet cylinder 16, and the bulb 14 below the top shell 19 is powered to make the light irradiate on the surface of the door panel of the civil air defense door. If the air pressure sensor 303 detects that the air pressure in the detection assembly 5 rises to a certain value and does not rise any more, the maximum value is the air pressure of the rated amount of high pressure gas in the detection assembly 5, which is recorded as the rated air pressure, and the light sensor 302 cannot receive the light signal, which indicates that the long side baffle 506 and the wide side baffle 507 are completely attached to the four sides of the civil air defense door panel to be detected, that is, the overall shape of the civil air defense door panel is qualified, and the air tightness is good.

[0062] On the basis of the above detection method, according to the change of the light sensor 302 and the air pressure sensor 303, the following analysis results can also be obtained:

[0063] Case one: If the air pressure sensor 303 detects that the air pressure rises to a certain value and does not rise any more, but the maximum air pressure value detected is less than the rated air pressure, after the delivery of the compressor 17 is completed, the air pressure sensor 303 detects that the air pressure gradually decreases, at the same time, the light sensor 302 receives the light signal, which indicates that the structure of the civil air defense door panel to be detected has defects, so that the sealing ring one cannot be attached to the four sides of the door panel, and there is a gap between the civil air defense door panel and the long side baffle 506 and the wide side baffle 507, so that the gas leaks through the gap, and the light irradiates on the surface of the light sensor 302 through the gap;

[0064] Further, if the light signal received by the light sensor 302 presents irregularly distributed points, it indicates that there are recessed or protruding areas in the outline of the civil air defense door panel, so that there is a small hole between the outline of the surface of the civil air defense door panel and the long side baffle 506 and the wide side baffle 507, and the light irradiates on the surface of the light sensor 302. The defects in the outline caused by small range recesses or protrusions can be corrected through subsequent repair operations.

[0065] Further, if the light signal received by the light sensor 302 presents one or more continuous bands, it indicates that one or more edges of the civil air defense door panel are inclined during production and manufacturing, so that there is a continuous gap between the inclined edge and the long side baffle 506 and the wide side baffle 507, and the light irradiates on the surface of the light sensor 302. The existence of the inclined edge or edges indicates that there is a problem in the production and manufacturing process of the civil air defense door panel, and the production should be stopped to investigate the problem, and the civil air defense door panel that does not meet the requirements should be scrapped.

[0066] Case two: if the light sensor 302 does not detect the light signal, but the air pressure sensor 303 detects that the air pressure rises to a certain value and does not rise any more, but the maximum air pressure value detected is less than the rated air pressure, when the compressor 17 delivery ends, the air pressure sensor 303 detects that the air pressure gradually decreases, indicating that the overall shape of the door panel itself is qualified, but there is a small gap in the structure of the door panel itself, which makes the gas leak through the gap;

[0067] Further, a plurality of groups of door panels should be detected to confirm the frequency of structural gaps in the door panels. If it is within the error range, the unqualified products will be scrapped separately. If it is greater than the error range, it indicates that there is a problem in the production process of the door panel itself, and the cause should be investigated in time.

[0068] Specifically, in step four, on the basis of step three, after confirming that the overall shape and air tightness of the detected door panel are qualified, the compressor 17 is used to deliver a rated amount of high-pressure gas into the detection assembly 5 in batches, so that the air pressure in the detection assembly 5 increases. If the door panel deforms under high pressure, specifically, the side under high pressure deforms. When the door panel deforms, the deformation inevitably causes gaps between the door panel and the long side baffle 506 and the wide side baffle 507, causing gas leakage. The air pressure sensor 303 detects a significant decrease in air pressure, records the maximum air pressure before the air pressure drops, and marks it as , , which is the maximum air pressure that can be withstood by one side of the door panel;

[0069] Further, due to the small space volume in the single detection assembly 5, the air pressure of the high-pressure gas quickly reaches , causing the door panel to deform rapidly for a short time, making it difficult to determine the maximum pressure that can be withstood by the elastic deformation and plastic deformation of the door panel. Replace the new door panel and perform the next detection.

[0070] Further, the support assembly 3 drives the door panel to move downward to the inside of the detection assembly 5 at the middle position, so that the bottom plate 301 and the sealing plate 12 of the middle detection assembly 5 are at the same horizontal height, and the door panel is located in the middle position of the space surrounded by the safety assembly 4 and the detection assembly 5. The space surrounded by the safety assembly 4 and the detection assembly 5 is called the detection space. Start the compressor 17 to deliver high-pressure gas, so that the air pressure in the entire detection space increases. At this time, the entire door panel is subjected to air pressure, and under the overall air pressure, the door panel structure collapses, which is manifested as irregular cracks or fractures in the overall structure of the door panel. Through the distribution of cracks or fracture points, the structural weak points of the door panel can be obtained, providing a reference for the structural design of the door panel.

[0071] Further, the control support assembly 3 drives the new civil air defense door panel to move downwards to the inside of the detection assembly 5, so that the bottom plate 301 is at the same level as the sealing plate one 12 of the lower detection assembly 5, at this time, the sealing ring two of the support assembly 3 is attached to the sealing plate one 12, and the sealing is completed, then the long side baffle 506 and the wide side baffle 507 are controlled to be attached to the surface of the civil air defense door panel, at this time, the space volume above the civil air defense door panel is the sum of the volumes of the three detection assemblies 5, in the case that the amount of high-pressure gas supplied by the compressor 17 is the same, the larger space volume makes the pressure of the rated amount of high-pressure gas decrease, in order to make the pressure reach the critical volume of the civil air defense door panel leakage, the same amount of high-pressure gas needs to be transported multiple times, in this process, the rising speed of the pressure is reduced, the slower rising speed of the pressure makes the deformation speed of the civil air defense door panel caused by the pressure lower, which can more accurately obtain the pressure value that the civil air defense door panel can withstand when it is elastically deformed and plastically deformed, and provides a basis for the selection of the production material of the civil air defense door panel.

[0072] Specifically, the slowly rising pressure makes the deformation rate of the civil air defense door panel slow, when the gap caused by the deformation appears, at this time, since the gap is small, the gas leakage rate is less than the delivery rate of the compressor 17, so that the gas pressure sensor 303 detects that the rising rate of the pressure is further reduced, and the pressure before the reduction is recorded as P1. At this time, the compressor 17 is stopped to supply gas, and when the gas supply is stopped, the gas continues to leak, so that the pressure gradually decreases, with the gradual decrease of the pressure, if the gas pressure sensor 303 detects that the pressure does not change after decreasing to a certain value, it means that the deformation of the civil air defense door panel gradually resets, so that the space returns to the sealed state, That is, the maximum pressure that the civil air defense door panel can withstand when it is plastically deformed;

[0073] Further, the compressor 17 intermittently delivers gas, the safety plate 406 in the safety assembly 4 is controlled to move relatively, so that the process hole one 13 of the sealing plate two 18 is opened, which is used to discharge the leaked gas to the external environment, to prevent the pressure of the leaked gas from affecting the detection result.

[0074] With the intermittent delivery of gas by the compressor 17, the deformation amount of the civil air defense door panel increases continuously, so that the gas leakage increases continuously, when the compressor 17 stops delivering gas, if the pressure at this time does not reach the critical pressure of plastic deformation, the gas pressure sensor 303 detects that the pressure decreases to a certain value and remains static, which means that the deformation of the civil air defense door panel resets, and the leaked pressure directly enters the external environment through the process hole one 13;

[0075] Since the process hole 13 of the sealing plate 2 18 is opened, the leaked gas continuously enters the outside, thus, when the air pressure sensor 303 detects that the air pressure gradually decreases until the same as the outside air pressure, it indicates that the deformation of the door plate of the civil air defense door resets, thus, the air pressure detected by the air pressure sensor 303 before the air pressure decreases is the maximum air pressure that can be borne by the plastic deformation;

[0076] Through the comparative analysis of the maximum air pressure that can be borne by the elastic deformation and the plastic deformation of the door plate of the civil air defense door with different materials, the selection of the production material of the door plate of the civil air defense door has a positive effect.
