[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. An efficient detection mechanism is provided. The hydraulic rod drives the sealed detection lifting box to move up and down to perform a sealing detection on the waterproof coiled material, and then drives the lifting rack to move up and down to engage and drive the driving gear. Through the multiple transmission linkages of the stable adjustment worm, transmission worm gear, large transmission wheel and small transmission wheel, the rotating shaft can rotate in different directions as the sealed detection lifting box rises and falls, which is convenient for adjusting the positions of the precise detection paper storage frame and the water collection tank. During the waterproof detection process, the water-soluble detection paper is pushed below the leakage detection notch to judge the result of the impermeability test. After the detection is completed, the water-soluble detection paper is pushed out, which is convenient for the staff to directly observe and obtain evidence; Moreover, the power source of the linkage is single, which is controlled by driving the movement of the sealed detection lifting box by the hydraulic rod, reducing the setting of the power mechanism and improving the utilization rate of power. The meshing mechanical transmission between the stable adjustment worm and the transmission worm gear makes the overall transmission process more stable and precise. The moving operation process has a controllable speed and is smoother, preventing jamming during the adjustment and replacement process. At the same time, it can be detected and repaired in time during the failure process. The large transmission wheel and the small transmission wheel cooperate with each other to play a synchronous operation linkage control, and the transmitted power can be directly applied to the rotating shaft, so that the movement of the rotating shaft, the precise detection paper storage frame and the water collection tank can be synchronized with the lifting of the sealed detection lifting box. Under the synchronous control, the movement of the structure is unified, preventing the subsequent positions from being inconsistent due to the operation time difference.

[0015] 2. The water-soluble detection paper is highly sensitive to water and will be dissolved and unable to maintain integrity after being wetted, which provides great convenience for the staff to judge whether there is water seepage. Moreover, the water collection tank is alternately moved below the leakage detection notch to collect the water used for subsequent detection, preventing the water from dripping everywhere after the tested waterproof coiled material is taken out and making the working environment messy. The positions of the water-soluble detection paper on the precise detection paper storage frame and the water collection tank correspond to the position and movement direction of the sealed detection lifting box. According to the test process, the precise detection paper storage frame and the water collection tank with different functions are adjusted and moved, and their position alternation is controlled by the lifting of the sealed detection lifting box, and the control is more precise.

[0016] 3. By using the combination of an air pump and an air-inflating adjustment airbag, the piston pressure plate is pressed downward, which compresses the air inside the sealing detection lifting box. By adjusting the pressure inside the sealing detection lifting box, the water impermeability of the waterproof coiled material under the corresponding pressure can be effectively tested. The test is more convenient to conduct, and the adjustment of the pressure is more convenient and fast. By using high pressure, the hidden gaps at the joints of the waterproof coiled material can be effectively detected; The air-inflating adjustment airbag changes its volume by inflating to adjust the air pressure inside the sealing detection lifting box. When inflating, the gas flow remains stable when entering the air-inflating adjustment airbag, enabling the uniform expansion of the air-inflating adjustment airbag. As a result, the pressure on the piston pressure plate is averaged, preventing the piston pressure plate from being skewed due to uneven pressure and getting stuck, and making the detection results more accurate.

[0017] 4. At the same time, the lifting sealing water-blocking plate can be used to seal and cover the drainage gap, preventing water from seeping downward before the test. And with the downward movement of the piston pressure plate, the two-way linkage traction rope can pull the lifting sealing water-blocking plate upward, allowing the water to flow downward automatically for the test. The reset spring plays a role of resetting and contracting, and can effectively push the lifting sealing water-blocking plate back to its original position to block the drainage gap after the test, facilitating the preparation of the water required for subsequent tests in the water storage tank in advance. The two-way linkage traction rope is controlled by the downward push of the piston pressure plate to adjust the pressure. The lifting and lowering of the piston pressure plate controls the lifting and lowering of the lifting sealing water-blocking plate through the two-way linkage traction rope, thereby alternately realizing the drainage and sealing operations. It is automatically controlled through linkage, eliminating the need for manual operation multiple times and making it more convenient to use. The protective sleeve protects the reset spring from being corroded and damaged due to long-term immersion in water.

[0018] 5. An air flow reuse water removal mechanism is provided. The air flow recovery exhaust valve can guide the air flow inside the air-inflating adjustment airbag, allowing it to be discharged outward through the gas distribution frame and the water removal and air drying holes. When the air flow is discharged downward, it blows against the inner wall of the bottom of the sealing detection lifting box and the inside of the leakage detection gap, playing a role of air drying the moisture generated after the water used in the test is discharged, removing the remaining water droplets inside the bottom of the sealing detection lifting box and the leakage detection gap, preventing the water droplets from dripping everywhere and causing the surrounding environment to be messy. And the residual water in the leakage detection gap will affect the subsequent test results. Using the existing resources for the follow-up aftercare work of the test improves the utilization rate of resources. The inclined guide plate plays a role of guiding the water used in the test, allowing it to flow along the inclined guide plate and the gas distribution frame into the leakage detection gap.

[0019] 6. By cooperating with each other, the laser receiver and the laser transmitter are used to control the operation of the air flow recovery exhaust valve, the hydraulic rod and the air pump. The control is more accurate, enabling the air flow recovery exhaust valve to open and close at corresponding stages, the hydraulic rod to drive the sealing detection lifting box to move to a corresponding position and stop, and the air pump to supplement the gas for cleaning. The winding wheel rotates synchronously with the stable adjustment worm to wind and lengthen the traction flat belt, thereby adjusting the position of the light-shielding control opening and closing block. When the sealing detection lifting box descends, the laser emitted by the laser transmitter is covered, enabling the test to proceed smoothly. After the test, when the sealing detection lifting box rises to a certain stage, it no longer covers the laser, and the laser is used to control structures such as the air flow recovery exhaust valve. At the same time, the automatically falling counterweight cylinder and the connecting spring respectively play a certain driving and limiting role during the rising and falling processes of the sealing detection lifting box, causing the position of the light-shielding control opening and closing block to vary at different stages of the lifting and lowering of the sealing detection lifting box. The control is more precise, and the gravity of the automatically falling counterweight cylinder itself can press down on the traction flat belt, pressing it down when power is lost and keeping it in a tensioned state.

[0020] In summary, by combining the efficient detection mechanism and the air flow reutilization and water removal mechanism, the concept of high-efficiency automation is realized for the overall process of the test. The test is continuously carried out through automatic control, and subsequent aftercare cleaning is also carried out simultaneously, making it more convenient and fast to use. Using the power of the hydraulic rod to push the sealing detection lifting box, multiple linkages are carried out through structures such as the driving gear, the stable adjustment worm, the transmission worm gear, and the transmission belt, realizing the synchronous operation of multiple structures with one power source. This enables the precise detection paper storage frame and the water collection tank to rotate synchronously with the sealing detection lifting box, achieving automatic control, making full use of the existing power resources. Moreover, the gas used for inflation and pressurization is reused for the second time to remove the water remaining after the water permeability test, also making full use of the existing resources. The inflation and contraction of the gas in the inflation adjustment airbag can drive the lifting of the sealing water blocking plate, giving it a certain linkage control function, fully improving the overall structure of the equipment, reducing the setting of power structures, effectively removing redundant power structures, making the overall structure design more reasonable and compact, and the mutual linkage smoother.

A sealed detection lifting box 302 is connected between the bottoms of the two hydraulic rods 301. A lifting rack 303 is installed at one edge of the sealed detection lifting box 302. A positioning block 304 is installed in the middle of one end of the workbench 1. A rotating shaft 305 is rotatably installed in the middle of the positioning block 304. The bottom end of the rotating shaft 305 is connected with a connecting block 306. One end of the connecting block 306 is connected with a precise detection paper storage frame 307. A water-soluble detection paper 308 is placed in the middle of the precise detection paper storage frame 307. The other end of the connecting block 306 is connected with a water collection tank 309. The tops of the precise detection paper storage frame 307 and the water collection tank 309 are both in contact with the bottom end of the workbench 1; A small transmission wheel 310 is installed on the top of the rotating shaft 305, and a mounting frame 311 is installed at the top of the workbench 1 at a position corresponding to the positioning block 304. A driving gear 312 is rotatably installed on one end of the top of the mounting frame 311. The positions of the driving gear 312 and the lifting rack 303 correspond to each other. A stabilizing adjustment worm 313 is installed on the top of the mounting frame 311 at a position on one side of the driving gear 312. A rotating rod 314 is rotatably installed in the middle of the top of the mounting frame 311. A transmission worm gear 315 is installed on the top of the rotating rod 314. The transmission worm gear 315 is located on one side of the stabilizing adjustment worm gear 313. The transmission worm gear 315 and the stabilizing adjustment worm gear 313 are meshed with each other. One end of the stabilizing adjustment worm gear 313 is fixedly connected to the middle of one end of the driving gear 312. A large transmission wheel 316 is installed in the middle of the rotating rod 314. A transmission belt 317 is sleeved on the middle of the large transmission wheel 316, and one end of the transmission belt 317 is close to the small transmission wheel 3 10, the large transmission wheel 316 and the small transmission wheel 310 are connected by a transmission belt 317, and the hydraulic rod 301 is used to drive the sealing detection lifting box 302 to move up and down, and the waterproof membrane 5 is sealed. Then, the lifting rack 303 is driven up and down, and the driving gear 312 is meshed and driven. After the multiple transmission linkages of the worm 313, the transmission worm wheel 315, the large transmission wheel 316 and the small transmission wheel 310 are stably adjusted, the rotating shaft 305 can rotate in different directions with the rise and fall of the sealing detection lifting box 302, which is convenient for adjusting the position of the precise detection paper storage frame 307 and the water collecting box 309. In the waterproof detection process, the water-soluble detection paper 308 is pushed to the bottom of the leakage detection gap 318 to judge the result of the impermeability test. After the detection is completed, the water-soluble detection paper 308 is pushed out, which is convenient for the staff to directly observe and collect evidence; The linkage power source is single, and the movement of the sealing detection lifting box 302 is driven by the hydraulic rod 301 for control, which reduces the setting of the power mechanism and improves the utilization rate of the power. The meshing mechanical transmission between the stable adjustment worm 313 and the transmission worm wheel 315 makes the overall transmission process more stable and accurate, and the speed of the moving operation process is controllable and smoother, which prevents the jamming phenomenon in the adjustment and transposition process. At the same time, it can be discovered and repaired in time during the failure process. The large transmission wheel 316 and the small transmission wheel 310 cooperate with each other to achieve synchronous linkage control, which can directly act on the rotating shaft 305. The movement of the rotating shaft 305, the precise detection paper storage frame 307 and the water collecting box 309 can be synchronized with the lifting of the sealing detection lifting box 302. Under synchronous control, the movement of the structure is kept unified to prevent the operation time difference from causing the subsequent positions to be inconsistent. The water-soluble test paper 308 is highly sensitive to water. After being wetted, it will be dissolved and unable to maintain its integrity, which provides great convenience for the staff to judge whether there is water leakage. Moreover, by alternately moving the water collection tank 309 below the water leakage detection notch 318, it plays a role in collecting the water used for subsequent detection, preventing the water from dripping everywhere after the waterproof coiled material 5 for the test is taken out and causing the working environment to be messy. The positions of the water-soluble test paper 308 and the water collection tank 309 on the precise test paper storage frame 307 correspond to the position and movement direction of the seal detection lifting box 302. According to the test process, the precise test paper storage frame 307 and the water collection tank 309 with different functions are adjusted and moved, and the position alternation of the two is controlled by the lifting of the seal detection lifting box 302, and the control is more precise; A water leakage detection notch 318 is opened in the middle of the top end of the workbench 1. A anti-falling support filter screen 319 is fixedly installed in the middle of the water leakage detection notch 318. A drain valve 320 is installed at the bottom end of the water collection tank 309. A waterproof coiled material 5 is placed inside the water leakage detection notch 318. The water leakage detection notch 318 is located directly below the seal detection lifting box 302. The length and width of the water leakage detection notch 318 are the same as those of the seal detection lifting box 302. The length and width of the water collection tank 309 are much larger than those of the water leakage detection notch 318. The waterproof coiled material 5 is closely attached to the surface of the anti-falling support filter screen 319. The bottom end of the anti-falling support filter screen 319 is flush with the bottom end of the workbench 1; At the top inside the sealed detection lifting box 302, an inflation adjustment airbag 321 is installed. The bottom end of the inflation adjustment airbag 321 is fixedly connected to a piston pressure plate 322. In the middle of the top end of the sealed detection lifting box 302, an air pump 323 is fixedly installed. The air outlet at the bottom of the air pump 323 is connected to the inflation adjustment airbag 321 through a pipeline. At both ends of the top of the piston pressure plate 322, limit edge blocks 324 are installed. A drainage notch 325 is opened in the middle of one end of the sealed detection lifting box 302. At the position corresponding to the drainage notch 325 on the surface of the sealed detection lifting box 302, a water storage tank 326 is fixedly installed. At the bottom end inside the water storage tank 326, protective sleeves 327 are symmetrically installed. Inside both protective sleeves 327, return springs 328 are fixedly installed. Between the top ends of the two return springs 328, a connecting plate 329 is installed. One end of the connecting plate 329 is fixedly connected to a lifting and sealing water blocking plate 330. The lifting and sealing water blocking plate 330 is located on one side of the drainage notch 325. The lifting and sealing water blocking plate 330 is in close fit with the inner wall of the water storage tank 326. On both sides of the water storage tank 326, support frames 331 are symmetrically and fixedly installed. Between the top ends of the two support frames 331, a wire winding and reversing round rod 332 is installed. At the top of the connecting plate 329, two-way linkage traction ropes 333 are symmetrically connected. The two-way linkage traction ropes 333 are closely attached to the surface of the top of the wire winding and reversing round rod 332. The two-way linkage traction ropes 333 are connected to the top of one limit edge block 324. By using the cooperation of the air pump 323 and the inflation adjustment airbag 321, the piston pressure plate 322 is extruded downward, which compresses the air inside the sealed detection lifting box 302, adjusts the pressure inside the sealed detection lifting box 302, and can effectively test the water impermeability of the waterproof coiled material 5 under the corresponding pressure. The test is more convenient to carry out, and the adjustment of the pressure is more convenient and fast. The hidden gaps at the joints of the waterproof coiled material 5 can be effectively detected by using high pressure. The inflation adjustment airbag 321 changes its volume by inflating to adjust the air pressure inside the sealed detection lifting box 302. When inflating, the gas flows and remains stable when entering the inflation adjustment airbag 321, making the inflation adjustment airbag 321 expand evenly, and then averaging the pressure on the piston pressure plate 322, preventing the piston pressure plate 322 from being skewed due to uneven pressure and getting stuck, and making the detection result more accurate; Meanwhile, the lifting and sealing water blocking plate 330 can be used to seal and cover the drainage gap 325, preventing water from seeping downward before the test. And with the downward movement of the piston pressure plate 322, the two-way linkage traction rope 333 can pull the lifting and sealing water blocking plate 330 upward, allowing the water to flow downward automatically for the test. The reset spring 328 plays a role of resetting and contracting. After the test, it can effectively push the lifting and sealing water blocking plate 330 back to its original position to block the drainage gap 325, facilitating the preparation of the water required for subsequent tests in the water storage tank 326 in advance. The two-way linkage traction rope 333 is controlled by the downward push of the piston pressure plate 322 to adjust the pressure. The lifting of the piston pressure plate 322 controls the lifting of the lifting and sealing water blocking plate 330 through the two-way linkage traction rope 333, thereby alternately realizing drainage and sealing operations. It is automatically controlled through linkage, eliminating the need for manual operation multiple times and making it more convenient to use. The protective sleeve 327 protects the reset spring 328, preventing the reset spring 328 from being corroded and damaged due to long-term immersion in water; An air flow reutilization and water removal mechanism 4 is installed at one end of the sealing detection lifting box 302; The air flow reutilization and water removal mechanism 4 includes an air flow recovery exhaust valve 401, an air pipe 402, a gas distribution frame 403, a water removal and air drying air hole 404, an inclined guide plate 405, a laser receiver 406, a laser transmitter 407, a base 408, a connecting spring 409, a guide post 410, a movable block 411, a light shielding control opening and closing block 412, a winding wheel 413, a guide frame 414, a guide groove 415, an automatically falling counterweight cylinder 416, a clamping and lifting cylinder 417, a fixed post 418, a limiting post 419, and a traction flat belt 420; In the middle of one end of the sealing detection lifting box 302, an air flow recovery exhaust valve 401 is fixedly installed. At the bottom end of the air flow recovery exhaust valve 401, an air pipe 402 is fixedly connected. At the bottom of the inner wall of the sealing detection lifting box 302, a gas shunt frame 403 is fixedly installed. At equal intervals at the bottom end of the gas shunt frame 403, water removal and air drying holes 404 are opened. At the four edges of the top end of the gas shunt frame 403, inclined diversion plates 405 are installed. The air flow recovery exhaust valve 401 and the inflation adjustment air bag 321 are connected by a hose. The air pipe 402 is connected to the gas shunt frame 403. The inclined diversion plates 405 are closely attached to the inner wall of the sealing detection lifting box 302. The air flow recovery exhaust valve 401 can guide the air flow inside the inflation adjustment air bag 321 to discharge it outward through the gas shunt frame 403 and the water removal and air drying holes 404. When the air flow discharges downward, it blows against the inner wall of the bottom end of the sealing detection lifting box 302 and inside the water leakage detection notch 318, playing a role in air drying the moisture generated after the water used in the test is discharged, removing the remaining water droplets inside the bottom end of the sealing detection lifting box 302 and the water leakage detection notch 318, preventing the water droplets from dripping everywhere and causing the surrounding environment to be messy. Moreover, the remaining water flow in the water leakage detection notch 318 will affect the subsequent test results. Using the existing resources for the follow-up aftermath work of the test improves the utilization rate of resources. The inclined diversion plates 405 play a role in guiding the water used in the test, enabling it to flow along the inclined diversion plates 405 and the gas shunt frame 403 into the water leakage detection notch 318; A laser receiver 406 is fixedly installed in the middle of one side of the sealed detection lifting box 302. A laser transmitter 407 is installed at the bottom of one end of the frame 2. The laser receiver 406 and the laser transmitter 407 are located in the same vertical plane. The signal output end of the laser receiver 406 is connected to the signal input ends of the hydraulic rod 301, the air inflation pump 323, and the air flow recovery exhaust valve 401. A base 408 is fixedly installed at the corresponding position of the top of the workbench 1 and the laser transmitter 407. A connecting spring 409 is installed in the middle of the top end of the base 408. Guide columns 410 are symmetrically installed at both ends of the top of the base 408. The top end of the connecting spring 409 is fixedly connected to a movable block 411. A light-shielding control opening and closing block 412 is installed in the middle of the top end of the movable block 411. The two guide columns 410 respectively pass through the two ends of the movable block 411 movably. The light-shielding control opening and closing block 412 corresponds to the position of the laser transmitter 407. One end of the stable adjustment worm 313 is fixedly connected to a winding wheel 413. A guide frame 414 is installed at the position on one side of the stable adjustment worm 313 at the top of the mounting frame 311. A guide groove 415 is formed in the middle of the guide frame 414. An automatically falling counterweight cylinder 416 is movably installed in the middle of the guide frame 414. Both ends of the automatically falling counterweight cylinder 416 are fixedly connected to clamping and lifting cylinders 417. A fixed column 418 is installed in the middle of one end of the frame 2. A limit column 419 is installed at one end of the fixed column 418. A traction flat belt 420 is wound around the middle of the winding wheel 413. Both ends of the automatically falling counterweight cylinder 416 are respectively in close contact with the two inner walls of the guide frame 414. The two clamping and lifting cylinders 417 are respectively clamped in the middle of the two guide grooves 415. The traction flat belt 420 is in close contact with the bottom surface of the automatically falling counterweight cylinder 416 and the surface of the top of the limit column 419. One end of the traction flat belt 420 is connected to the top end of the light-shielding control opening and closing block 412. By using the mutual cooperation of the laser receiver 406 and the laser transmitter 407, the operation of the air flow recovery exhaust valve 401, the hydraulic rod 301, and the air inflation pump 323 is controlled. The control is more accurate, enabling the air flow recovery exhaust valve 401 to open and close at corresponding stages, the hydraulic rod 301 to drive the sealed detection lifting box 302 to move to the corresponding position and stop, and the air inflation pump 323 to supplement the gas for cleaning; The take-up wheel 413 rotates synchronously with the stable adjustment worm 313 to wind up and extend the traction flat belt 420, thereby adjusting the position of the light-shielding control opening and closing block 412, covering the laser emitted by the laser emitter 407 when the sealing detection lifting box 302 descends, enabling the test to proceed smoothly. After the test, when the sealing detection lifting box 302 rises to a certain stage, it no longer covers the laser, and uses it to control structures such as the air flow recovery exhaust valve 401. At the same time, the automatically falling counterweight cylinder 416 and the connecting spring 409 respectively play a certain driving and limiting role during the ascending and descending processes of the sealing detection lifting box 302, causing the position of the light-shielding control opening and closing block 412 to vary at different stages of the ascending and descending of the sealing detection lifting box 302, making the control more precise.

[0025] The working principle and usage process of the present invention: First, the staff places the waterproof coiled material 5 to be tested into the leakage detection notch 318 and spreads it flat on the surface of the anti-falling support filter screen 319. The hydraulic rod 301 extends downward, pushing the sealing detection lifting box 302 downward. When the lifting rack 303 descends with the sealing detection lifting box 302, it meshes with the driving gear 312, thereby driving the driving gear 312 and the stable adjustment worm 313 to rotate. When the stable adjustment worm 313 rotates, it meshes with the transmission worm wheel 315, driving the transmission worm wheel 315 and the large transmission wheel 316 to rotate synchronously. The transmission belt 317 plays a transmission role, driving the small transmission wheel 310 and the rotating shaft 305 to rotate, and adjusting the positions of the precise detection paper storage frame 307 and the water collection tank 309. The water collection tank 309 gradually moves from the bottom of the workbench 1, and the precise detection paper storage frame 307 gradually moves towards the bottom of the leakage detection notch 318. When the bottom end of the sealing detection lifting box 302 is embedded inside the leakage detection notch 318 and tightly presses on the surface of the waterproof coiled material 5, the precise detection paper storage frame 307 is located directly below the leakage detection notch 318, and the water-soluble detection paper 308 is closely attached to the bottom end of the anti-falling support filter screen 319; At the same time, during the descending process of the sealing detection lifting box 302, the stable adjustment worm 313 drives the take-up wheel 413 to rotate and wind up the traction flat belt 420. During the winding-up process, since the connecting spring 409 pulls down the movable block 411 and the light-shielding control opening and closing block 412, the traction flat belt 420 first pulls the automatically falling counterweight cylinder 416 to move upward along the guide groove 415 until the automatically falling counterweight cylinder 416 reaches the top of the guide frame 414 and can no longer move upward. Then, the traction flat belt 420 pulls the light-shielding control opening and closing block 412 to move upward, the connecting spring 409 is stretched, and the movable block 411 and the light-shielding control opening and closing block 412 move upward along the guide post 410. The light-shielding control opening and closing block 412 blocks the laser emitted by the laser emitter 407, so that after the sealing detection lifting box 302 continues to descend, the laser receiver 406 cannot capture and sense the laser; Next, the air inflation pump 323 is started to inflate the inside of the air inflation adjustment airbag 321. The air flow recovery exhaust valve 401 is closed. The inflated gas causes the air inflation adjustment airbag 321 to expand downward, pushing the piston pressure plate 322 downward. The limit edge block 324 descends along with the piston pressure plate 322. Furthermore, the double-direction linkage traction rope 333 is used to pull the connecting plate 329 and the lifting and sealing water blocking plate 330 upward, so that the lifting and sealing water blocking plate 330 cannot block the drainage gap 325. The water prepared in the water storage tank 326 flows into the inside of the sealing detection lifting box 302 from the drainage gap 325. The height of the prepared water level should be lower than the top of the protective sleeve 327 to prevent the water from corroding the return spring 328. The discharged water flows downward along the surfaces of the inclined diversion plate 405 and the gas diversion frame 403 into the water leakage detection gap 318. Since the sealing detection lifting box 302 is closely attached to the surface of the waterproof coiled material 5, the bottom of the sealing detection lifting box 302 is sealed, and the water will stay on the surface of the waterproof coiled material 5. The water is used to test the water impermeability at the joint of the waterproof coiled material 5. If the joint of the waterproof coiled material 5 is waterproof, the water flow always exists on the surface of the waterproof coiled material 5. If the water impermeability at the joint of the waterproof coiled material 5 is poor, resulting in the water flow penetrating downward from the joint, the water droplets will pass through the anti-falling support filter screen 319 and drip onto the surface of the water-soluble detection paper 308; Then, the air inflation pump 323 continuously inflates the air inflation adjustment airbag 321, causing the piston pressure plate 322 to continuously descend. At this time, both the inside of the sealing detection lifting box 302 and the water storage tank 326 are sealed. The piston pressure plate 322 will squeeze the air inside the sealing detection lifting box 302, increasing its internal pressure, which plays a role in pressurizing the water on the surface of the waterproof coiled material 5. The water impermeability at the joint of the waterproof coiled material 5 is tested after pressurization. After the air inflation pump 323 pressurizes for a certain period of time, it stops running, so that the waterproof coiled material 5 maintains a certain pressure for a period of time; After the pressure test for a period of time, the hydraulic rod 301 contracts upward, pulling the sealing detection lifting box 302 upward. During the upward movement, the lifting rack 303 meshes with the driving gear 312 again, pushing the driving gear 312 and the stable adjustment worm 313 to rotate in the reverse direction. Furthermore, the small transmission wheel 310 and the rotating shaft 305 both rotate in the reverse direction to adjust the positions of the precise detection paper storage frame 307 and the water collection tank 309, so that the precise detection paper storage frame 307 gradually moves away from the bottom of the workbench 1, and the water collection tank 309 gradually moves downward to the lower part of the water leakage detection gap 318. The stable adjustment worm 313 will drive the winding wheel 413 to rotate, playing a role in lengthening the traction flat belt 420. The connecting spring 409 is in a stretched state. When the traction flat belt 420 is lengthened, the connecting spring 409 will first gradually contract and reset, stretching and tensioning the lengthened traction flat belt 420, pulling the light-shielding control opening and closing block 412 downward, and no longer covering the laser emitted by the laser emitter 407; Not until the sealing detection lifting box 302 moves upward by a certain height, the irradiated laser is captured by the laser receiver 406, and then the hydraulic rod 301 is controlled not to contract anymore. At this time, the precise detection paper storage frame 307 moves outward to a certain position, while the water collection tank 309 moves under the workbench 1. Since the length and width of the water collection tank 309 are much larger than those of the water leakage detection notch 318, when the sealing detection lifting box 302 rises halfway, the part of the water collection tank 309 that moves under the workbench 1 is sufficient to cover the bottom of the water leakage detection notch 318. The staff takes out the waterproof coiled material 5 for detection, and the water inside the water leakage detection notch 318 flows through the anti-falling support filter screen 319 into the inside of the water collection tank 309. At the same time, the air flow recovery exhaust valve 401 is controlled to open, and the gas inside the inflation adjustment airbag 321 is transmitted to the inside of the gas shunt frame 403 along the air flow recovery exhaust valve 401 and the air pipe 402. The inflation adjustment airbag 321 gradually resets and contracts as the air flows out, and the exhausted air drives and promotes the water droplets adhering to the inner wall of the bottom end of the sealing detection lifting box 302 and the water droplets remaining inside the water leakage detection notch 318, so that they can converge and pass through the anti-falling support filter screen 319 and be discharged. After the gas inside the inflation adjustment airbag 321 is discharged, the air pump 323 is started again to output gas inward, which plays a certain role in air drying and prevents the residual moisture inside the water leakage detection notch 318 and the anti-falling support filter screen 319 from affecting subsequent tests; During the process of the air flow cleaning the water droplets, part of the precise detection paper storage frame 307 is moved out of the bottom of the workbench 1. The staff takes out the water-soluble detection paper 308 inside the precise detection paper storage frame 307. According to the integrity of the water-soluble detection paper 308, it can be judged whether water drips from the anti-falling support filter screen 319 during the test process, and then the water impermeability of the joint of the waterproof coiled material 5 can be judged. If the joint of the waterproof coiled material 5 leaks, the water droplets pass through the anti-falling support filter screen 319 and drip on the water-soluble detection paper 308, which will cause partial dissolution of the water-soluble detection paper 308, making the water-soluble detection paper 308 unable to remain intact. If the water-soluble detection paper 308 still remains intact, it indicates that the joint of the waterproof coiled material 5 is water-impermeable; After a period of time, the cleaning of the residual water is completed, the air flow recovery exhaust valve 401 is closed, the air inflation pump 323 stops operating, the air inflation adjustment airbag 321 contracts and pulls the piston pressure plate 322 back to its original position. The bidirectional linkage traction rope 333 gradually relaxes the connecting plate 329 and the lifting and sealing water blocking plate 330. The return spring 328 contracts and pulls the lifting and sealing water blocking plate 330 to block the drainage notch 325 again. The staff injects the water required for the next test into the interior of the water storage tank 326, and the water surface does not exceed the top of the protective sleeve 327. The hydraulic rod 301 is used to pull the sealing detection lifting box 302 up again, so that the precise detection paper storage frame 307 is completely moved out, and the water collection tank 309 is completely moved under the workbench 1. The winding wheel 413 rotates continuously to lengthen the traction flat belt 420. The connecting spring 409 has been fully reset, and the automatic falling counterweight cylinder 416 will gradually slide down along the guide groove 415 to press and tension the traction flat belt 420.
