[0028] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0029] 1. A detection mechanism is provided, which uses a hydraulic rod to drive the sealing detection lifting box to move up and down, performs sealing detection on the waterproof membrane, and then drives the lifting rack to move up and down, engages and drives the driving gear, and through the stable adjustment of the multiple transmission linkage of the worm, transmission worm wheel, large transmission wheel and small transmission wheel, the rotating shaft can rotate in different directions as the sealing detection lifting box rises and falls, which is convenient for adjusting the position of the precise detection paper storage frame and the water collection tank. During the waterproof detection process, the water-soluble detection paper is pushed to the bottom of the water leakage detection gap to judge the result of the impermeability test. After the test is completed, the water-soluble detection paper is pushed out, which is convenient for the staff to directly observe and collect evidence;

[0030] Moreover, the linkage power source is single, and the movement of the sealing detection lifting box is driven by a hydraulic rod for control, which reduces the setting of the power mechanism and improves the utilization rate of power. The meshing mechanical transmission between the stable adjustment worm and the transmission worm wheel makes the overall transmission process more stable and precise, and the moving operation process speed is controllable and smoother, preventing jamming during the adjustment and transposition process. At the same time, it can be discovered and repaired in time during the occurrence of faults. The large transmission wheel and the small transmission wheel cooperate with each other to play a role in the linkage control of synchronous operation, 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 box can be synchronized with the lifting of the sealing detection lifting box. Under synchronous control, the movement of the structure remains unified to prevent the operation time difference from causing the subsequent positions to be inconsistent.

[0031] 2. The water-soluble test paper is highly sensitive to water and will be dissolved and unable to maintain its integrity after being stained with water. This greatly facilitates the staff in judging whether there is water seepage. The water collecting box is alternately moved to the bottom of the leakage detection gap to collect water for subsequent testing, preventing water from dripping everywhere and causing a dirty working environment after the tested waterproof membrane is taken out. The position of the water-soluble test paper and the water collecting box on the precise test paper storage frame corresponds to the position and movement direction of the sealing detection lifting box. The precise test paper storage frame and the water collecting box with different functions are adjusted and moved according to the test process. The position of the two is controlled by the lifting of the sealing detection lifting box, which makes the control more precise.

[0032] 3. By using the air pump and the air-adjusting airbag together, the piston pressure plate is pressed downward to compress the air inside the sealing test lift box. By adjusting the pressure inside the sealing test lift box, the waterproof membrane's impermeability under the corresponding pressure can be effectively tested. The test is more convenient to conduct, and the pressure adjustment is more convenient and quick. The use of high pressure can effectively detect hidden gaps in the joints of the waterproof membrane.

[0033] The inflatable regulating airbag changes its volume by inflation and thus adjusts the air pressure inside the sealing detection lifting box. During inflation, the gas flows and remains stable when entering the inflatable regulating airbag, so that the inflatable regulating airbag expands evenly, and then the pressure on the piston pressure plate is evenly distributed, preventing the piston pressure plate from being unevenly pressurized and skewed, resulting in jamming, and the detection results are more accurate.

[0034] 4. At the same time, the lifting sealing water blocking plate can be used to seal and cover the drainage gap to prevent water from penetrating downward before the test, and the downward movement of the piston pressure plate can be used to pull the lifting sealing water blocking plate upward, so that water can automatically flow out downward for testing. The reset spring plays a role of reset and contraction. After the test, it can effectively push the lifting sealing water blocking plate back to its original position to block the drainage gap, so that the water required for subsequent tests can be prepared in advance inside the water storage tank. The piston pressure plate is pushed downward to adjust the pressure to control the two-way linkage traction rope. The lifting and lowering of the piston pressure plate is controlled by the two-way linkage traction rope, thereby alternately realizing drainage and sealing operations. It is automatically controlled through linkage, and there is no need for manual operation multiple times. It is more convenient to use. The protective sleeve protects the reset spring to prevent the reset spring from being soaked in water for a long time and causing rust damage.

[0035] 5. An airflow reuse and water removal mechanism is provided, and the airflow recovery exhaust valve can be used to guide the airflow inside the inflatable regulating airbag, so that it is discharged outward through the gas diversion frame and the water removal and drying air holes. When the airflow is discharged downward, it blows to the inner wall of the bottom end of the sealing detection lifting box and the inside of the leakage detection gap, which has a drying effect on the moisture generated after the water used in the test is discharged, and removes the residual water droplets at the bottom end of the sealing detection lifting box and the inside of the leakage detection gap, preventing water droplets from dripping everywhere and causing the surrounding environment to be dirty, and the water flow remaining in the leakage detection gap will affect the subsequent test results. The existing resources are used to carry out the subsequent follow-up work of the test, which improves the utilization rate of resources. The inclined guide plate has a diversion effect on the water used in the test, so that it can flow along the inclined guide plate and the gas diversion frame to the inside of the leakage detection gap.

[0036] 6. The laser receiver and laser transmitter work together to control the operation of the airflow recovery and exhaust valve, hydraulic rod and air pump. The control is more accurate, so that the airflow recovery and exhaust valve opens and closes at the corresponding stage, the hydraulic rod drives the sealing detection lifting box to move to the corresponding position and stop, and the air pump replenishes the gas for cleaning;

[0037] The winding wheel rotates synchronously with the stable adjustment worm to reel in and lengthen the traction flat belt, thereby adjusting the position of the shading control opening and closing block, and covering the laser emitted by the laser transmitter when the sealing detection lifting box descends, so that the test can proceed smoothly. After the test, the sealing detection lifting box rises to a certain stage and no longer covers the laser, and is used to control structures such as the airflow recovery exhaust valve. At the same time, the automatic falling counterweight cylinder and the connecting spring respectively play a certain driving and limiting role in the rising and falling process of the sealing detection lifting box, so that the position of the shading control opening and closing block is different at different stages of the sealing detection lifting box, and the control is more precise. The gravity of the automatic falling counterweight cylinder itself can press down the traction flat belt, pressing it down when it loses power while keeping it in a tensioned state.

[0038] In summary, by combining the detection mechanism and the airflow reuse and water removal mechanism, the concept of efficient automation is realized for the overall process of the test. The test is carried out continuously through automated control, and the subsequent cleanup is also carried out at the same time, which is more convenient and quick to use. The hydraulic rod is used to push the sealing detection lifting box with one power, and multiple linkages are performed through structures such as driving gears, stable adjustment worms, transmission worm wheels and transmission belts, realizing one power operation and multiple structures running synchronously, so that the precise detection paper storage frame and the water collection box can rotate synchronously with the sealing detection lifting box, realizing automated control, and making full use of existing power resources. The gas used for inflation and pressurization is also reused for a second time, and the gas is used to remove the residual water in the water permeability test, which also makes full use of existing resources. The gas can expand and contract the inflation adjustment airbag to drive the lifting and lowering of the sealing water blocking plate, so that it also has a certain linkage control effect, fully improving the overall structure of the equipment, reducing the power structure setting, and effectively reducing the redundant power structure, making the overall structural design more reasonable and compact, and the mutual linkage is smoother.

[0054] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0055] Example: Figure 1-9 As shown, the present invention provides a technical solution, a waterproof membrane joint impermeability test device, comprising a workbench 1, a frame 2 is installed on the top of the workbench 1, and a detection mechanism 3 is installed in the middle of the frame 2;

[0056] The detection mechanism 3 includes a hydraulic rod 301, a sealing detection lifting box 302, a lifting rack 303, a positioning block 304, a rotating shaft 305, a connecting block 306, a precise detection paper storage frame 307, a water-soluble detection paper 308, a water collecting tank 309, a small transmission wheel 310, a mounting frame 311, a driving gear 312, a stabilizing adjustment worm 313, a rotating rod 314, a transmission worm gear 315, a large transmission wheel 316, a transmission belt 317, a water leakage detection gap 318, an anti-drop support filter 319, a drain valve 320, an inflation adjustment airbag 321, a piston pressure plate 322, an air pump 323, a limiting edge block 324, a drainage gap 325, a water storage tank 326, a protective sleeve 327, a return spring 328, a connecting plate 329, a lifting sealing water blocking plate 330, a support frame 331, a winding reversing round rod 332 and a two-way linkage traction rope 333;

[0057] Hydraulic rods 301 are symmetrically fixedly installed in the middle of the frame 2, and a sealing detection lifting box 302 is connected between the bottom ends of the two hydraulic rods 301. A lifting rack 303 is installed on the edge of one end of the sealing 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 to a connecting block 306. One end of the connecting block 306 is connected to a precise detection paper storage frame 307. 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 to a water collecting tank 309. The top ends of the precise detection paper storage frame 307 and the water collecting tank 309 are both in contact with the bottom end of the workbench 1.

[0058] The top of the mounting bracket 311 is provided with a small transmission wheel 310, and the top of the working table 1 is provided with a mounting bracket 311 at a position corresponding to the positioning block 304. A driving gear 312 is rotatably mounted on one end of the mounting bracket 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 bracket 311 at a position on one side of the driving gear 312. A rotating rod 314 is rotatably mounted in the middle of the top of the mounting bracket 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 313. The transmission worm gear 315 and the stabilizing adjustment worm 313 mesh with each other. One end of the stabilizing adjustment worm 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. One end of the transmission belt 317 is close to the small transmission wheel 3 316 and 317 are connected by a transmission belt 317. The hydraulic rod 301 drives the sealing detection lifting box 302 to move up and down to perform sealing detection on the waterproof membrane 5, thereby driving the lifting rack 303 to move up and down, meshing and driving the driving gear 312, and stably adjusting the multiple transmission linkage of the worm 313, the transmission worm gear 315, the large transmission wheel 316 and the small transmission wheel 310, so that the rotating shaft 305 can rotate in different directions as the sealing detection lifting box 302 rises and falls, making it convenient to adjust the position of the precise detection paper storage frame 307 and the water collection box 309. During the waterproof detection process, the water-soluble detection paper 308 is pushed to the bottom of the water leakage detection gap 318 to judge the result of the water-tightness 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.

[0059] The linkage power source is single, and the movement of the sealing detection lifting box 302 is controlled by the hydraulic rod 301, which reduces the setting of the power mechanism and improves the power utilization rate. The meshing mechanical transmission between the stable adjustment worm 313 and the transmission worm gear 315 makes the overall transmission process more stable and accurate, and the speed of the moving operation process is controllable and smoother, which prevents jamming during the adjustment and transposition process. At the same time, it can be discovered and repaired in time during the occurrence of a fault. The large transmission wheel 316 and the small transmission wheel 310 cooperate with each other to achieve a synchronous linkage control, which can directly act on the rotating shaft 305 to ensure the movement of the rotating shaft 305, the precise detection paper storage frame 307 and the water collection box 309. The movement can be synchronized with the lifting of the sealing detection lifting box 302. Under synchronous control, the movement of the structure remains unified, which prevents the operation time difference from causing the subsequent positions to be inconsistent.

[0060] The water-soluble test paper 308 is highly sensitive to water and will be dissolved and lose its integrity after being stained by water, which greatly facilitates the staff in judging whether there is water seepage. In addition, the water collecting box 309 is alternately moved to the bottom of the water leakage detection gap 318 to collect water for subsequent detection, thereby preventing water from dripping everywhere after the tested waterproofing membrane 5 is taken out, causing a dirty working environment. The positions of the water-soluble test paper 308 and the water collecting box 309 on the precise test paper storage frame 307 correspond to the position and movement direction of the sealing detection lifting box 302. The precise test paper storage frame 307 and the water collecting box 309 with different functions are adjusted and moved according to the test process. The positions of the two are controlled by the lifting and lowering of the sealing detection lifting box 302, which makes the control more precise.

[0061] A water leakage detection gap 318 is provided in the middle of the top of the workbench 1. An anti-drop support filter 319 is fixedly installed in the middle of the water leakage detection gap 318. A drain valve 320 is installed at the bottom of the water collecting box 309. A waterproof coil 5 is placed inside the water leakage detection gap 318. The water leakage detection gap 318 is located directly below the sealing detection lifting box 302. The length and width of the water leakage detection gap 318 are the same as the length and width of the sealing detection lifting box 302. The length and width of the water collecting box 309 are much larger than the length and width of the water leakage detection gap 318. The waterproof coil 5 is tightly attached to the surface of the anti-drop support filter 319, and the bottom end of the anti-drop support filter 319 is flush with the bottom end of the workbench 1.

[0062] An inflatable regulating airbag 321 is installed at the top of the sealing detection lifting box 302, and a piston pressure plate 322 is fixedly connected to the bottom of the inflatable regulating airbag 321. An inflatable pump 323 is fixedly installed in the middle of the top of the sealing detection lifting box 302. The air outlet at the bottom of the inflatable pump 323 and the inflatable regulating airbag 321 are connected by a pipe. Limiting edge blocks 324 are installed at both ends of the top of the piston pressure plate 322. A drainage notch 325 is opened in the middle of one end of the sealing detection lifting box 302. At the position corresponding to the drainage notch 325 on the surface of the sealing detection lifting box 302, A water storage tank 326 is fixedly installed, and a protective sleeve 327 is symmetrically installed at the bottom end of the water storage tank 326. Reset springs 328 are fixedly installed inside the two protective sleeves 327. A connecting plate 329 is installed between the tops of the two reset springs 328. One end of the connecting plate 329 is fixedly connected to a lifting sealing water blocking plate 330. The lifting sealing water blocking plate 330 is located on one side of the drainage gap 325. The lifting sealing water blocking plate 330 fits tightly with the inner wall of the water storage tank 326. Support frames 331 are symmetrically fixed on both sides of the water storage tank 326. The two support frames 331 are fixedly installed on the sides of the water storage tank 326. A winding reversing rod 332 is installed between the top ends, and a two-way linkage traction rope 333 is symmetrically connected to the top of the connecting plate 329. The two-way linkage traction rope 333 is close to the surface of the top of the winding reversing rod 332, and the two-way linkage traction rope 333 is connected to the top of a limiting edge block 324. The air pump 323 and the air adjustment airbag 321 are used in conjunction to squeeze the piston pressure plate 322 downward, compressing the air inside the sealing detection lifting box 302, and adjusting the pressure inside the sealing detection lifting box 302, which can effectively test the waterproof membrane. 5 is under the corresponding pressure, the impermeability test is more convenient to carry out, and the pressure adjustment is more convenient and quick. The use of high pressure can effectively detect the hidden gaps at the joints of the waterproof membrane 5. The inflatable regulating airbag 321 changes its volume by inflation and thus adjusts the internal air pressure of the sealing detection lifting box 302. When inflated, the gas flows and remains stable when entering the inflatable regulating airbag 321, so that the inflatable regulating airbag 321 expands evenly, and then the pressure of the piston pressure plate 322 is evenly distributed, preventing the piston pressure plate 322 from being unevenly pressurized and skewed, resulting in jamming, and more accurate test results;

[0063] When the water tank 326 is closed, the water tank 326 is opened, and the water tank 326 is opened, and the water tank 326 is opened.

[0064] An airflow reuse and water removal mechanism 4 is installed at one end of the sealing detection lifting box 302;

[0065] The airflow recycling and dewatering mechanism 4 includes an airflow recovery and exhaust valve 401, an air delivery pipe 402, a gas diversion frame 403, a dewatering 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 column 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 lifting cylinder 417, a fixing column 418, a limiting column 419, and a traction flat belt 420.

[0066] An airflow recovery exhaust valve 401 is fixedly installed in the middle of one end of the sealing detection lifting box 302, and the bottom end of the airflow recovery exhaust valve 401 is fixedly connected to the air supply pipe 402. A gas diversion frame 403 is fixedly installed at the bottom of the inner wall of the sealing detection lifting box 302. The bottom end of the gas diversion frame 403 is equidistantly provided with dewatering and air-drying air holes 404. The four sides of the top of the gas diversion frame 403 are all equipped with inclined guide plates 405. The airflow recovery exhaust valve 401 and the inflation regulating airbag 321 are connected by a hose, and the air supply pipe 402 is connected to the gas diversion frame 403. The inclined guide plate 405 is close to the inner wall of the sealing detection lifting box 302. The airflow recovery exhaust valve 401 can be used to guide the airflow inside the inflation regulating airbag 321 so that it passes through the gas The diverter frame 403 and the water removal and drying air holes 404 are discharged outwards, and the air flow is blown toward the inner wall of the bottom end of the sealing detection lifting box 302 and the inside of the water leakage detection gap 318 when discharged downwards, which has the effect of drying the moisture generated after the water used in the test is discharged, and removes the water droplets remaining at the bottom end of the sealing detection lifting box 302 and the inside of the water leakage detection gap 318, preventing water droplets from dripping everywhere and causing a dirty environment. The water flow remaining in the water leakage detection gap 318 will affect the subsequent test results. Existing resources are used for the follow-up work of the test, which improves the utilization rate of resources. The inclined guide plate 405 has a diversion effect on the water used in the test, so that it can flow along the inclined guide plate 405 and the gas diverter frame 403 to the inside of the water leakage detection gap 318;

[0067] A laser receiver 406 is fixedly installed in the middle of one side of the sealing detection lifting box 302, and 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 on the same vertical plane. The signal output end of the laser receiver 406 is connected to the signal input end of the hydraulic rod 301, the signal input end of the air pump 323 and the signal input end of the airflow recovery exhaust valve 401. A base 408 is fixedly installed at the top of the workbench 1 at a position corresponding to the laser transmitter 407. A connecting spring 40 is installed in the middle of the top of the base 408. 9. Guide columns 410 are symmetrically installed at both ends of the top of the base 408. The top of the connecting spring 409 is fixedly connected to a movable block 411. A shading control opening and closing block 412 is installed in the middle of the top of the movable block 411. The two guide columns 410 are movable through the two ends of the movable block 411. The shading control opening and closing block 412 corresponds to the position of the laser emitter 407. One end of the stabilizing and adjusting worm 313 is fixedly connected to a winding wheel 413. A guide frame 414 is installed on the top of the mounting frame 311 at one side of the stabilizing and adjusting worm 313. The middle part of the guide frame 414 is opened. A guide groove 415 is provided, and an automatic falling counterweight cylinder 416 is movably installed in the middle of the guide frame 414. Both ends of the automatic falling counterweight cylinder 416 are fixedly connected with a clamping lifting cylinder 417. A fixed column 418 is installed in the middle of one end of the frame 2, and a limit column 419 is installed at one end of the fixed column 418. A traction flat belt 420 is wrapped around the middle of the winding wheel 413. The two ends of the automatic falling counterweight cylinder 416 are respectively close to the two inner walls of the guide frame 414. The two clamping lifting cylinders 417 are respectively clamped in the middle of the two guide grooves 415. The traction flat belt 420 is close to the automatic The bottom surface of the falling counterweight cylinder 416 and the top surface of the limiting column 419, and one end of the traction flat belt 420 are connected to the top of the light-shielding control opening and closing block 412. The laser receiver 406 and the laser transmitter 407 cooperate with each other to control the operation of the airflow recovery and exhaust valve 401, the hydraulic rod 301 and the air pump 323. The control is more accurate, so that the airflow recovery and exhaust valve 401 is opened and closed at the corresponding stage, the hydraulic rod 301 drives the sealing detection lifting box 302 to move to the corresponding position and stop, and the air pump 323 replenishes the cleaning gas;

[0068] The winding wheel 413 rotates synchronously with the stabilizing adjustment worm 313 to wind up and lengthen the traction flat belt 420, thereby adjusting the position of the shading control opening and closing block 412, and covering the laser emitted by the laser emitter 407 when the sealing detection lifting box 302 descends, so that the test can proceed smoothly. After the test is completed, the sealing detection lifting box 302 rises to a certain stage and no longer covers the laser, and is used to control structures such as the airflow 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 rising and falling process of the sealing detection lifting box 302, so that the position of the shading control opening and closing block 412 is different at different stages of the rising and falling of the sealing detection lifting box 302, and the control is more precise.

[0069] The working principle and use process of the present invention are as follows: First, the staff puts the waterproof membrane 5 to be tested into the leakage detection gap 318 and lays it flat on the surface of the anti-drop support filter 319. The hydraulic rod 301 extends downward to push the sealing detection lifting box 302 to move downward. As the sealing detection lifting box 302 descends, the lifting rack 303 engages with the driving gear 312, thereby driving the driving gear 312 and the stabilizing adjustment worm 313 to rotate. When the stabilizing adjustment worm 313 rotates, it engages with the transmission worm wheel 315, driving the transmission worm wheel 315 and the large transmission wheel 316 to rotate synchronously, and the transmission belt 3 17 plays a transmission role, driving the small transmission wheel 310 and the rotating shaft 305 to rotate, adjusting the positions of the precise detection paper storage frame 307 and the water collecting box 309, and the water collecting box 309 gradually moves from the bottom of the workbench 1, and the precise detection paper storage frame 307 gradually moves to the bottom of the water leakage detection gap 318. When the bottom end of the sealing detection lifting box 302 is embedded in the water leakage detection gap 318 and is tightly pressed against the surface of the waterproof coiled material 5, the precise detection paper storage frame 307 is located directly below the water leakage detection gap 318, and the water-soluble detection paper 308 is tightly attached to the bottom end of the anti-drop support filter 319;

[0070] At the same time, during the descending process of the sealing detection lifting box 302, the stabilizing adjustment worm 313 will drive the winding wheel 413 to rotate and reel in the traction flat belt 420. During the reeling 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 will first pull the automatic falling counterweight cylinder 416 to move upward along the guide groove 415 until the automatic falling counterweight cylinder 416 reaches the top of the guide frame 414 and cannot move upward any further, the traction flat belt 420 will pull the light shielding control opening and closing block 412 to move upward, the connecting spring 409 is stretched, the movable block 411 and the light shielding control opening and closing block 412 move upward along the guide column 410, and the light shielding control opening and closing block 412 will block the laser emitted by the laser transmitter 407, so that after the sealing detection lifting box 302 continues to descend, the laser receiver 406 cannot capture and sense the laser.

[0071] Then, the air pump 323 is started to fill the air into the air-inflating regulating airbag 321, and the air flow recovery exhaust valve 401 is closed. The filled air causes the air-inflating regulating airbag 321 to expand downward, pushing the piston pressure plate 322 downward. The limiting edge block 324 descends with the piston pressure plate 322, and then the two-way linkage traction rope 333 is used to pull the connecting plate 329 and the lifting sealing water blocking plate 330 upward, so that the lifting sealing water blocking plate 330 cannot block the drainage gap 325. The water prepared in advance in the water storage tank 326 flows into the sealing detection lifting box 302 from the drainage gap 325. The prepared water level must be lower than the height of the top of the protective sleeve 327 to prevent water from flowing out. The return spring 328 is rusted, and the discharged water flows downward along the surface of the inclined guide plate 405 and the gas diversion frame 403 into the water leakage detection gap 318. Since the sealing detection lifting box 302 is tightly attached to the surface of the waterproof membrane 5, the bottom of the sealing detection lifting box 302 is sealed, and the water will remain on the surface of the waterproof membrane 5. The water is used to test the watertightness of the joints of the waterproof membrane 5. If the joints of the waterproof membrane 5 are watertight, water will always flow on the surface of the waterproof membrane 5. If the watertightness of the joints of the waterproof membrane 5 is poor, the water will penetrate downward from the joints, and the water droplets will pass through the anti-drop support filter 319 and drip onto the surface of the water-soluble detection paper 308.

[0072] Then, the air pump 323 continues to inflate the air-regulating airbag 321, causing the piston pressure plate 322 to continue to descend. At this time, the interiors of the sealing detection lifting box 302 and the water storage tank 326 remain sealed. The piston pressure plate 322 squeezes the air inside the sealing detection lifting box 302, increasing its internal pressure and pressurizing the water on the surface of the waterproof membrane 5. The watertightness of the joints of the waterproof membrane 5 after pressurization is tested. After the air pump 323 pressurizes for a certain period of time, it stops running, allowing the waterproof membrane 5 to maintain this pressure for a period of time.

[0073] After a period of pressure test, the hydraulic rod 301 contracts upward, pulling the sealing detection lifting box 302 up. During the rising process, the lifting rack 303 engages with the driving gear 312 again, pushing the driving gear 312 and the stabilizing adjustment worm 313 to rotate in the opposite direction, and then the small transmission wheel 310 and the rotating shaft 305 rotate in the opposite direction, adjusting the positions of the precise detection paper storage frame 307 and the water collecting box 309, so that the precise detection paper storage frame 307 gradually moves away from the bottom of the workbench 1, and the water collecting box 309 gradually moves below the leakage detection gap 318, and the stabilizing adjustment worm 313 drives the winding wheel 413 to rotate, which plays 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 stretched, the connecting spring 409 will first gradually shrink and reset, stretching and tensioning the stretched traction flat belt 420, pulling the shading control opening and closing block 412 down, and no longer covering the laser emitted by the laser emitter 407;

[0074] Until the sealing detection lifting box 302 moves up to a certain height, the irradiated laser is captured by the laser receiver 406, and then the hydraulic rod 301 is controlled to no longer retract. At this time, the precise detection paper storage frame 307 moves outward to a certain position, and the water collecting box 309 moves to the bottom of the workbench 1. Since the length and width of the water collecting box 309 are much larger than the length and width of the leakage detection gap 318, when the sealing detection lifting box 302 rises to the middle, the water collecting box 309 moves to the part below the workbench 1, which is enough to cover the bottom of the leakage detection gap 318. The staff takes out the waterproof membrane 5 for detection, and the water inside the leakage detection gap 318 flows into the water collecting box 309 through the anti-drop support filter 319, and the airflow is recovered at the same time. The exhaust valve 401 is controlled to open, and the gas inside the inflation regulating airbag 321 is transmitted to the inside of the gas diversion frame 403 along the airflow recovery exhaust valve 401 and the air supply pipe 402. The inflation regulating airbag 321 gradually returns to its original position and contracts as the airflow is discharged, and the discharged airflow 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 gap 318, so that they can converge and pass through the anti-drop support filter 319 for discharge. After the gas inside the inflation regulating airbag 321 is discharged, the inflation pump 323 is started again to output gas inward, which plays a certain role in drying, thereby preventing the residual moisture inside the water leakage detection gap 318 and the anti-drop support filter 319 after the test from affecting subsequent tests;

[0075] During the process of the airflow 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 has dripped from the anti-drop support filter 319 during the test, and then the water-tightness of the joints of the waterproof membrane 5 can be judged. If the joints of the waterproof membrane 5 leak, water droplets pass through the anti-drop support filter 319 and drip onto the water-soluble detection paper 308, which will cause partial dissolution of the water-soluble detection paper 308, making it impossible for the water-soluble detection paper 308 to remain intact. If the water-soluble detection paper 308 remains intact, it indicates that the joints of the waterproof membrane 5 are watertight.

[0076] After a period of time, the residual water is cleaned up, the air recovery exhaust valve 401 is closed, the inflation pump 323 stops running, the inflation regulating airbag 321 contracts, and the piston pressure plate 322 returns to its original position. The two-way linkage traction rope 333 gradually relaxes the connecting plate 329 and the lifting sealing water blocking plate 330. The reset spring 328 returns to its original position and contracts, pulling the lifting sealing water blocking plate 330 to block the drainage gap 325 again. The staff injects the water needed for the next test into the water storage tank 326, and the water level 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 box 309 is completely moved under the workbench 1. The reel 413 continues to rotate, lengthening 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, pressing down and tightening the traction flat belt 420.
