Common types include masonry, concrete, insulation, and new composite boards, etc. Their performance needs to meet basic requirements such as strength, durability, and environmental protection, which directly affect the structural safety and use of the wall. Building wall water penetration testing is a key means of detecting the waterproof performance of the wall. It is usually simulated by natural rainfall, specific area waterlogging, etc. in combination with auxiliary tools to locate the leakage point, and is applied to building construction quality control, completion acceptance compliance verification, and existing building leakage hidden trouble investigation.

Finally, it is discharged through the discharge pipe. In this way, during testing, the negative and positive pressures inside the plate rectangular frame can be switched by opening and closing the valves and pipelines, thereby increasing the test mode of the plate and improving the test effect of the structure. 3. When heat-assisted testing is required, the electric heater is started to heat the water inside the plate rectangular frame, and the temperature sensor senses the heating temperature of the water. The structure can be used under pressure and heat conditions for extreme testing, thereby increasing the number of test modes and improving the test effect. BRIEF DESCRIPTION OF DRAWINGS

[0029] The working principle of the above technical solution is as follows: in use, the user processes and cuts the wall material to be detected into regular rectangular plates, and applies new material to the plates. The plates are placed on the opposite sides of the side frame 16 and the front frame 17, and there are a total of five plates. The plates are placed on the opposite sides of the suction nozzle 30 and the top of the sealing rubber plate two 43, respectively, and the five plates are spliced into a rectangular container. During this process, the position of the sliding magnet slider 27 inside the sliding groove 26 is adjusted according to the size of the plates, so that the communication seat 28 and the suction nozzle 30 are located at the balanced force point of the plates, and the air pipe joint 29 is connected to the air pressure adsorption equipment through a flexible pipeline. The plates are placed outside the suction nozzle 30, and the air pressure adsorption equipment is connected to the air pipe joint 29 through the suction hose, so that the inside of the communication seat 28 and the suction nozzle 30 forms a negative pressure to adsorb the plates. Then the electric control telescopic rod 14 is started to push the side frame 16 and the front frame 17 closer, and the grid of the side frame 16 and the front frame 17 is misaligned to make the structure can be contracted and expanded within a certain range, for adapting to different specifications and sizes of plates. After splicing, the bottom plate is placed on the top of the sealing rubber plate two 43, and the hydraulic telescopic column 38 is retracted to move the sealing piston 39 inside the support cylinder 37, so that the inside of the support cylinder 37 and the support ring 40 forms a negative pressure to adsorb the plates. After positioning the five plates, sealant is applied to the joint edges of the plates to make the structure stable. After forming, the closed box door 2 is closed for testing. First, the water pump 4 pumps water into the inside of the pressure hose one 18 through the water outlet pipe 5, and then through the pressure hose one 18 to the inside of the ring cylinder 32. Finally, the water is sprayed on the inside of the plates through the flow guide hole 35, so that the water forms a pool on the inside of the rectangular frame. At this time, if the plates leak, the water will overflow through the plates and be guided to the water storage cylinder 44 through the hollow support plate 24 and the flow guide frame 25. The liquid level sensor 45 detects the signal and determines whether the plates and the coated material have serious leakage. If there is no leakage or the water seepage is not obvious, the hydraulic telescopic rod 20 is started to move downward to drive the ring cylinder 32 and the sealing rubber plate one 36 downward, and the sealing rubber plate one 36 is placed on the top of the plates to form a compression seal on the top of the plates, so that the sealing rubber plate one 36 and the plates form a closed hollow rectangular structure. Then the vacuum pump 31 is started to send air through the air blower 12 without heating, and the airflow is sucked in through the input pipe 11 and the communication pipe 10, and then input into the inside of the pressure hose two 19 through the flow guide pipe one 8, and then guided into the ring cylinder 32 through the pressure hose two 19. Finally, the airflow enters the rectangular space of the plates through the flow guide hole 35. At this time, the U-shaped pipe 7 and the exhaust pipe 9 are closed, and the inside of the ring cylinder 32 and the rectangular space of the plates forms a pressure boosting operation, and the water and the plates are subjected to pressure. The waterproof air pressure sensor 33 reacts to the size of the air pressure, and the infrared thermal imaging equipment detects the plates and the coated new material to determine the leakage point. If there is still no leakage point, the electric heater 22 is started to heat the water, so as to heat the plates. In this way, the leakage of the plates and the material under extreme pressure and temperature conditions is determined. The overall measurement is stable.And can adapt to a certain size range of wall plate water, shorten the test time, indirectly increase the test efficiency.

[0030] In another embodiment, as shown in Figures 1-6 The side frame 16 and the normal frame 17 are linearly staggered in the interior of the box 1, and the side frame 16 and the normal frame 17 are uniformly distributed in the interior of the box 1, and the side frame 16 and the normal frame 17 are linearly distributed and spliced in the form of a rectangular grid frame, the fixed part of the electric control telescopic rod 14 is fixedly installed on the inner wall of the box 1, and the four positioning telescopic sleeves 15 are uniformly distributed in the opposite sides of the side frame 16 and the normal frame 17, and the fixed part of the four positioning telescopic sleeves 15 is fixedly installed on the inner wall of the box 1.

[0031] The side frame 16 and the normal frame 17 provide opening positions for the sliding groove 26 and sliding tracks for the magnet slider 27, and the staggered distribution of the side frame 16 and the normal frame 17 allows the structure to be staggered and connected during use, thereby expanding and shrinking within a certain size range to measure different sizes of plate materials within a certain range. For the measurement of coated materials, the coated material is coated on the smooth plate with holes, and combined with the test principle and method, if the material seeps out, the water seeps out through the holes in the plate. In this way, different wall materials can be measured, increasing the use effect. The holes of the plate are uniformly distributed and bypass the distribution position of the suction nozzle 30. The positioning telescopic sleeve 15 is a sleeve without active extension, and the distance between the side frame 16 and the normal frame 17 is adjusted by the electric control telescopic rod 14. The positioning telescopic sleeve 15 helps to reduce the deviation and stabilize the structure.

[0032] In another embodiment, as shown in Figures 1-6 The top ends of the side frame 16 and the normal frame 17 are flush, the top ends of the side frame 16 and the normal frame 17 are both open, and the opening is in communication with the interior of the sliding groove 26, and the magnet slider 27 is uniformly distributed in the interior of the sliding groove 26.

[0033] The top ends of the side frame 16 and the normal frame 17 are cut flush with the plate, which facilitates the sliding of the magnet slider 27 into the interior of the sliding groove 26, thereby adjusting the number and position of the magnet slider 27, the communication seat 28 and the suction nozzle 30 according to the size of the measured plate, ensuring stable support and adjusting according to the point position, increasing the overall adaptability and facilitating the adjustment of the position according to the actual situation.

[0034] In another embodiment, as shown in Figures 1-10As shown, the inside of the hollow support plate 24 is fixedly sleeved with a support cylinder 37, the top of the support cylinder 37 is communicated with a support ring 40, the top of the support ring 40 is fixedly installed with a sealing rubber plate two 43, a plurality of air holes 41 are arranged in the inside of the support ring 40 and the sealing rubber plate two 43, the air holes 41 are uniformly distributed in the inside of the support ring 40 and the sealing rubber plate two 43, a plurality of magnet blocks 42 are fixedly installed in the inside of the support ring 40, the magnet blocks 42 are linearly and uniformly distributed in the inside of the support ring 40, the inside of the support cylinder 37 movably sleeved with a sealing piston 39, the bottom of the sealing piston 39 is fixedly installed with a hydraulic telescopic column 38, the bottom end of the hydraulic telescopic column 38 is fixedly installed on the top of the flow guide frame 25 through a support.

[0035] The plate material at the bottom is arranged on the top of the sealing rubber plate two 43, and the hydraulic telescopic column 38 is started to retract to drive the sealing piston 39 to move in the support cylinder 37, so that the inside of the support cylinder 37 and the support ring 40 forms a negative pressure to adsorb the plate material, the air pressure drives the movement of the plate material to exert a pressing force on the sealing rubber plate two 43, so as to ensure the stability of the structure, and the magnet blocks 42 can increase the adsorption of the ferromagnetic plate material to form a relatively stable support at the bottom of the spliced plate material.

[0036] In another embodiment, as shown in the drawings, Figures 1-10 The bottom end of the flow guide frame 25 is communicated with a water storage cylinder 44, the inside of the water storage cylinder 44 is provided with a liquid level sensor 45, the inside of the bottom end of the water storage cylinder 44 is installed with an electric valve 46, a plurality of discharge holes 47 are arranged in the inside of the bottom end of the water storage cylinder 44, the discharge holes 47 are uniformly distributed in the inside of the bottom end of the water storage cylinder 44, the bottom end of the water storage cylinder 44 is fixedly installed on the bottom of the inner cavity of the box body 1, and the inside of the discharge valve 13 is provided with a valve.

[0037] When the measured plate material has a more serious water leakage, at this time, the water flow enters the inside of the water storage cylinder 44 through the hollow support plate 24 and the flow guide frame 25, and the liquid level sensor 45 detects the water to feedback to the control system, and when the measurement is completed, the electric valve 46 is opened to discharge the water flow, the water flow is discharged to the bottom of the inner cavity of the box body 1 through the discharge holes 47, and finally the valve of the discharge valve 13 is opened to discharge, which is to detect the water leakage amount in a certain time when a large range of water leakage occurs, so as to assist the operation and increase the use effect.

[0038] In another embodiment, as shown in the drawings, Figures 1-10 The ring cylinder 32 is circular, the bottom end of the flow guide hole 35 penetrates the ring cylinder 32 and the fixed frame 34 and extends to the bottom of the sealing rubber plate one 36, the flow guide hole 35 is uniformly arranged in the bottom of the inner cavity of the ring cylinder 32, and the specification size of the fixed frame 34 and the sealing rubber plate one 36 is larger than that of the side frame 16 and the vertical frame 17.

[0039] The structure of the ring cylinder 32 provides a relatively stable limit for air flow and water flow, and finally uniformly leads out through the flow guide hole 35. When the hydraulic telescopic rod 20 promotes the downward movement of the ring cylinder 32, the sealing rubber plate 36 can completely cover the top of the side frame 16 and the positive frame 17 and the position of the rectangular plate material, thereby achieving an auxiliary sealing effect and increasing the use effect of the structure.

[0040] In another embodiment, as shown in Figures 1-6 The top end of the front of the box body 1 is movably provided with a sealed box door 2, and the inner walls of the box body 1 are provided with infrared thermal imaging image acquisition ends on both sides.

[0041] The sealed box door 2 is convenient to open and assist the workers to arrange the plate material, and facilitates the use of the structure, thereby increasing the stability. The infrared thermal imaging image acquisition ends provided in the box body 1 assist the infrared thermal imaging equipment to detect the exuding points of the plate material during forming, thereby increasing the detection and auxiliary judgment capability.

[0042] In another embodiment, as shown in Figures 1-7 The bottom end of the water outlet pipe 5 is fixedly penetrated through the box body 1 and extends to the top of the inner cavity of the box body 1. The bottom end of the pressure-resistant hose 18 is communicated in the inside of the ring cylinder 32. The hot air blower 12 is fixedly installed on the top of the box body 1. The flow guide pipe 8 is fixedly penetrated through the box body 1 and extends to the top of the inner cavity of the box body 1. The bottom end of the pressure-resistant hose 19 is communicated in the inside of the ring cylinder 32. The U-shaped pipe 7 is communicated in the inside of the flow guide pipe 8 away from the one end of the communication pipe 10. The U-shaped pipe 7 spans on both sides of the discharge pipe 9. The insides of the water outlet pipe 5, the exhaust pipe 6, the U-shaped pipe 7, the discharge pipe 9, the input pipe 11, the pressure-resistant hose 18 and the pressure-resistant hose 19 are provided with electromagnetic valves.

[0043] The rectangular space formed by the plate material and the coating material is tested. The measurement force is increased by applying air pressure, and the positive pressure and the negative pressure are switched when needed, so as to obtain better test effect. When the structure is tested under negative pressure, the electromagnetic valves in the insides of the pressure-resistant hose 19, the U-shaped pipe 7 and the discharge pipe 9 are opened, and the electromagnetic valves in the insides of the flow guide pipe 8 and the input pipe 11 are closed. When the vacuum pump 31 is started, the air flow is first extracted from the insides of the flow guide pipe 8 and the pressure-resistant hose 19 through the communication of the communication pipe 10 and the U-shaped pipe 7, and is output to the inside of the other end of the flow guide pipe 8 divided by the electromagnetic valve through the output end of the vacuum pump 31, and finally is discharged through the discharge pipe 9. In this way, during the test, the negative pressure and the positive pressure in the inside of the rectangular frame of the tested plate material can be switched by switching the opening and closing of the valves and the pipes, so as to increase the test mode of the plate material and increase the test effect of the structure.
