[0022] The air jet hole 2002 is inclined downward to prevent dirty water flowing down the inner wall of the sealing tube 2 from flowing into the air collecting cavity 2001 through the air jet hole 2002 .

[0023] It also includes a protrusion 112; a plurality of protrusions 112 are fixedly connected to the upper inner side of the sealing cylinder 2; the protrusion 112 is located above the sealing rubber 9.

[0024] The driving assembly includes an electric push rod 101, a fixed frame 102, a motor 103, an electric guide rail 104, a moving block 105 and a ring frame 106; the placement table 1 is fixedly connected to two electric guide rails 104 distributed front and back, the electric guide rails 104 are connected to an external power supply, and each electric guide rail 104 is slidably connected to two moving blocks 105; all the moving blocks 105 are commonly fixedly connected to the ring frame 106; the ring frame 106 is fixedly connected to four electric push rods 101; the telescopic parts of all the electric push rods 101 are commonly fixedly connected to the fixed frame 102; the fixed frame 102 is fixedly connected to the motor 103, and the electric guide rails 104 and the motor 103 are respectively connected to the external power supply; the output shaft of the motor 103 is fixedly connected to the sealing cylinder 2; the sealing cylinder 2 is rotationally connected to the fixed frame 102.

[0025] It also includes an electric control valve 201; the sealing cylinder 2 is provided with a discharge hole 2003; the electric control valve 201 is fixedly connected to the discharge hole 2003 of the sealing cylinder 2; and the electric control valve 201 is connected to an external power supply.

[0026] The discharge hole 2003 is located at a low-lying area of ​​the inner bottom wall of the sealing cylinder 2, so that dirty water can be discharged to the discharge hole 2003 easily.

[0027] A plurality of grooves 6003 are provided on the outer side of the annular plate of the water spray frame 6 to facilitate the discharge of dirty water mixed with dust and water from the grooves 6003 to the inner bottom wall of the sealing tube 2 .

[0028] The specific working steps are: When it is necessary to inspect the produced prefabricated wall, firstly, the wall is lifted to the top of the placement table 1 by an external crane, and then the rectangular wall is driven down and placed flat on the placement table 1. After the wall is placed, the lower side of the wall will squeeze the upper side of the sealing rubber ring 10, so that the wall and the sealing rubber ring 10 are in close contact. At this time, the sealing tube 2, the sealing rubber ring 10 and the wall will form a sealed space, and then the external device manually connects the air supply pipe of the external air supply device with the air intake pipe 3, and then the external air supply device transports water vapor to the air intake pipe 3, and the water vapor will enter the gas collecting cavity 2001, and then be ejected from the air jet hole 2002. At this time, the ejected water vapor will be sprayed into the sealed space. As the water vapor in the sealed space increases, the air pressure in the sealed space will also increase. At this time, the high-pressure gas will drive the water vapor to move to the holes or gaps in the wall, thereby diffusing upward in the wall. When the water vapor in the wall gradually increases, the water vapor will be discharged upward from the wall. At this time, a humidity sensor can be placed on the upper part of the wall. When the humidity is detected to be rising, it means that the wall is prone to water seepage, which in turn affects the safety of the house, thereby detecting the safety of the wall. If the humidity does not change after a long period of detection, it means that the wall has strong water-proof properties and is also safe. Moreover, since the detection is carried out through water vapor, when it is detected that the wall has strong water-proof properties, it can be said that when the south wind returns, water vapor is not easy to enter the room through the gas. The strong water-proof properties of the wall can effectively avoid the problem of high water vapor content in the room and mold and rust of furniture.

[0029] Considering that during house construction, the prefabricated wall will be cut or opened, and after the prefabricated wall is cut or opened, the cut or opened part of the prefabricated wall becomes thinner than other parts. At this time, the water seepage resistance of the cut or opened part of the prefabricated wall cannot be ensured. Therefore, the electric push rod 101 is first controlled to drive the fixed frame 102, the motor 103 and the sealing cylinder 2 to descend, so that the sealing cylinder 2 is away from the wall, and then the sealing rubber ring 10 is pulled out to separate the sealing rubber ring 10 from the sealing cylinder 2, and then the electric guide rail 104 is controlled to drive the moving block 105 to drive the annular frame 106, the electric push rod 101, the fixed frame 102, the motor 103 and the sealing cylinder 2 to move to the right. It should be noted that Figure 1The side where the number of the placement table 1 is located is the right side. Then the electric push rod 101 drives the motor 103, the sealing cylinder 2, the air inlet pipe 3, the connecting frame 4, the water inlet pipe 5 and the water spray frame 6 to rise through the fixing frame 102. While rising, the motor 103 is controlled to drive the sealing cylinder 2 to rotate counterclockwise from a top-down perspective. At this time, the sealing cylinder 2 will rotate and rise to punch holes in the wall to simulate the cutting or opening operation of the prefabricated wall during house construction. It should be noted that the distance that the sealing cylinder 2 will rotate and rise to punch holes in the wall can be controlled by the electric push rod 101, so that the sealing cylinder 2 can be easily cut and opened. The sealing tube 2 is inserted into the wall, and then the electric push rod 101 and the motor 103 stop driving the sealing tube 2 to rise and rotate respectively. It should be noted that the maximum distance that the electric push rod 101 pushes the sealing tube 2 to rise is when the lower side of the wall is close to the water spray frame 6, that is, the lower side of the wall will not block the water spray hole 6002, and then the air supply pipe of the external air supply equipment is plugged into the air supply pipe 7, and then the external air supply equipment delivers gas to the air supply pipe 7, so that the gas enters the airbag 8. At this time, the airbag 8 will expand and squeeze the sealing rubber 9 to deform it, and the deformed sealing rubber 9 will be in close contact with the wall, thereby making the sealing tube 2 and the sealing The sealing rubber 9 and the gas form a sealed space, and then the external air supply equipment is used to transport water vapor to the air inlet pipe 3, and the water vapor will enter the gas collecting cavity 2001, and then be ejected from the air jet hole 2002. Since the contact area between the sealing rubber 9 and the wall is at the upper part of the cutting groove of the prefabricated wall, the gas will rise along the gap between the wall and the sealing cylinder 2 until it rises to the lower part of the sealing rubber 9, and then penetrate into the wall. At this time, the water vapor will penetrate upward at the middle position of the wall, thereby simulating the water vapor penetration when the prefabricated wall is cut or opened, so as to detect the cutting or opening of the prefabricated wall. The water-proof property after thinning is poor after the wall is cut or opened. The residents can be reminded to take waterproof measures after grooving, or to improve the wall production process to enhance its water-proof property. It should be noted that since the sealing cylinder 2 will rotate and rise to drill holes in the wall, the distance can be controlled by the electric push rod 101, so the water-proof property of different cutting or drilling depths can be tested. At the same time, when the water-proof property of prefabricated walls is tested under the same process, holes can also be drilled in the prefabricated walls, that is, the water-proof property of prefabricated walls under different thicknesses can be tested through the drilling operation.

[0030] Considering that after the sealing cylinder 2 is drilled, debris particles will be attached to the wall and the side of the sealing rubber 9 facing the center of the sealing cylinder 2, which will cause a gap between the sealing rubber 9 and the wall. At this time, water vapor will be discharged from the gap, resulting in air leakage, and dust will also adhere to the sealing cylinder 2. When water vapor enters the sealing cylinder 2, the dust attached to the inside of the sealing cylinder 2 will absorb the moisture in the water vapor, thereby causing scaling. After the inspection, the sealing cylinder 2 needs to be cleaned, which increases the workload of the workers. Therefore, before sending in steam, the water supply pipe of the external water supply equipment is manually connected to the water inlet pipe 5, and then the external water supply equipment sends water to the water inlet pipe 5, and the sent water will pass through the The water inlet pipe 5, the water collecting cavity 4001 and the water spraying cavity 6001 are finally sprayed out from the water spraying hole 6002, and the water will be sprayed into the gap between the sealing tube 2 and the wall. At this time, the sprayed water will clean the wall, the sealing tube 2 and the sealing rubber 9. When cleaning the attached dust, open the electric control valve 201. Since the discharge hole 2003 and the electric control valve 201 are located in the low-lying area of ​​the inner bottom wall of the sealing tube 2, the dirty water formed by cleaning flows to the discharge hole 2003. At this time, the discharged dirty water can be collected by an external collection device, thereby preventing dust from affecting the seal and causing air leakage. It can also avoid the dirt formed by dust, which requires subsequent cleaning work and increases the burden on staff.

[0031] It should be noted that the above-mentioned method of using water to clean dust is adopted instead of using vacuum to extract the dust because the vacuum cannot completely suck away the dust, and some dust will still adhere to the inner wall of the sealing tube 2, and the dust attached to the wall and the sealing rubber 9 is more difficult to be sucked away. Therefore, there are unavoidable disadvantages in using vacuum to suck away the dust.

[0032] When drilling, the sealing cylinder 2 will be in close contact with the wall. The gap after drilling is small, and water is not easy to spray into the gap. A long cleaning time is required to flush water into the gap. In addition, when drilling, it is easy for the sealing rubber 9 to contact with the wall, which will cause wear and tear, affecting the service life. Therefore, when drilling, the protrusion 112 will also contact the wall and grind a part of the wall to increase the gap between the sealing cylinder 2 and the wall, making it easier to spray water into the deep gap, facilitate dust cleaning, and speed up the cleaning speed. After the distance between the sealing cylinder 2 and the wall becomes larger, the sealing rubber 9 can also be prevented from being worn, thereby preventing the service life of the sealing rubber 9 from being affected. Example 2

[0033] On the basis of Example 1, Figure 5As shown, it also includes a paddle 111; the paddle 111 is fixedly connected to the connecting rod of the water spray frame 6; the paddle 111 is provided with eight connecting holes 11101; the connecting holes 11101 are connected to the water spray cavity 6001; the connecting rod of the water spray frame 6 is rotatably connected to the connecting frame 4.

[0034] A prefabricated wall safety detection method based on construction engineering, the specific steps are as follows: Step 1: Drill into the wall through the sealing tube 2, and then spray water vapor into the sealed space through the external air supply equipment and the air inlet pipe 3 to perform water seepage inspection; Step 2: Use the external water supply equipment in conjunction with the connecting frame 4, the water inlet pipe 5 and the water spraying frame 6 to perform dust reduction and cleaning work in the sealing cylinder 2 to prevent dust from affecting the detection; Step 3: When the sealing cylinder 2 is drilling, the protrusion 112 grinds part of the wall, so that the gap between the wall and the sealing cylinder 2 becomes larger, thereby facilitating water spraying into the wall for cleaning; Step 4: When water enters the connecting frame 4, the water impacts the slurry blades 111, causing the water spray frame 6 to rotate, and then the water spray frame 6 sprays in a rotating manner, which is beneficial to speed up the cleaning and dust reduction speed.

[0035] The specific working steps are: When water is sprayed out from the water inlet pipe 5 and enters the water collecting cavity 4001, the sprayed water will impact the paddle 111, so that the paddle 111 drives the water spray frame 6 to rotate clockwise when viewed from a top-down angle, so that the water sprayed from the water spray hole 6002 of the water spray frame 6 is in a rotating state, which is conducive to speeding up the cleaning and dust reduction speed and avoiding affecting the detection efficiency; it should be noted that the water in the water collecting cavity 4001 will enter the water spray cavity 6001 through the connecting hole 11101.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
