The device for detecting quality defects of building interior walls can adjust the height of the device by reducing or adding the number of intermediate plates through the design of detachable bottom plate, intermediate plate and top plate, so that the detection device can be adjusted to adapt to the inner surface of building walls of different heights. The device has a larger activity space and can detect the lower part of the wall and the high places at different heights, thereby improving the comprehensiveness of the device detection and ensuring the safe use of the building. However, the detection device needs to prepare multiple intermediate plates in advance before use to cope with the use requirements of different heights, and multiple intermediate plates are not convenient to carry. In addition, there are racks matching the gears on the surfaces of the bottom plate, the middle plate, and the top plate. After frequent disassembly, assembly, and transportation, the racks may be damaged to varying degrees, which may affect the subsequent meshing with the gears, causing the detector to jitter when moving or even unable to move normally. The image scanned by the detector may also be distorted and distorted due to the shaking of the detector, which is not conducive to subsequent analysis and judgment. Summary of the invention

[0016] Working principle: When in use, the turntable and the fixed frame 1 can be driven to rotate by the servo motor 1, and then the threaded rod and the slider inside the fixed frame 1 can drive the connecting rod 1 to rotate under the restriction of the cross plate. At the same time, because the rotating rod 1, the vertical plate and the horizontal plate can only move up and down due to the action of the hollow tube and the guide tube, the connecting plate connected to the connecting rod 1 and the rotating rod 1 can swing when the connecting rod 1 rotates, and then a thrust can be applied to the rotating rod 1 to drive the vertical plate, the horizontal plate and the infrared thermal imager to move up and down within a certain range through the rotating rod 1. In addition, when the slide plate and the cross plate are pulled up to overcome the pressure applied by the spring, as the cross plate gradually loses contact with the threaded rod, the threaded rod can be driven to rotate inside the fixed frame 1 by rotating the connecting rod 2, and further, with the cooperation of the fixed frame 1, the slider can be made to move along the threaded rod. The rod moves to make the connecting rod 1 move from the central area of ​​the turntable to its edge position. At this time, the slide plate is released, and the cross plate can be kept in contact with the threaded rod through the corresponding cross-shaped cavity inside the threaded rod under the action of the spring. As the positions of the slider and the connecting rod 1 change, the vertical movement range of the rotating rod 1, the vertical plate, the horizontal plate and the infrared thermal imager can be increased when the turntable and the fixed frame 1 rotate again, so that the infrared thermal imager can scan walls of different heights, avoiding the problem of unclear scanning images when the infrared thermal imager is placed at a relatively far position to scan the higher part of the wall. At the same time, the movement between the various components is simple and reliable, and the probability of failure caused by external environmental factors when used in the building to be accepted is relatively low. In addition, the up and down movement of the horizontal plate is used Movement, before starting the infrared thermal imager, the transmission rod and the impeller 1 can be driven to rotate by the servo motor 2, so as to continuously generate suction to suck air into the air inlet bin, and then the air can enter the air outlet bin through the rubber tube and blow the wall when the horizontal plate moves up and down, so as to prevent a large amount of dust from adhering to the wall and affecting the subsequent use of the infrared thermal imager, and a small amount of air can enter the air duct after being blocked by the baffle ring, and then a thrust can be applied to the impeller 2 inside the hollow bin when passing through the hollow bin, so that the impeller 2 drives the rotating rod 2 and the cam to rotate, and as the cam rotates, it can push the T-shaped plate up and down with the assistance of the positioning rod and the limit plate, and the evenly distributed blades connected to the T-shaped plate can swing back and forth around the connection between the middle part and the fixed frame 2 when the T-shaped plate moves up and down, so as to The wind direction of the air discharged from the air outlet bin is constantly changed, thereby enhancing the sweeping effect of the airflow on the dust. In addition, the dust separated from the wall can continue to move into the air inlet bin with the air, and after being blocked by the orifice plate, most of the dust can be blocked on the surface of the orifice plate, and with the rotation of the transmission rod, the scraper can continuously scrape the dust gathered on the surface of the orifice plate into the water outside the partition frame to collect the dust in the air and prevent it from affecting the use of the infrared thermal imager. At the same time, as the scraper enters a part of the water body and leaves the water body, a small amount of water can be smeared on the surface of the orifice plate with the scraper, thereby utilizing the dust holding capacity of the water body to enhance the dust filtering effect, and the air can also reduce its temperature after passing through the orifice plate with water on the surface, thereby achieving the purpose of quickly reducing the wall temperature while cleaning the dust.In order to affect the thermal balance of the wall, and to transfer heat by enhancing the temperature difference between the inside and outside of the wall, the abnormal area of ​​heat transfer can be more clearly found when the infrared thermal imager is used later, so as to avoid the infrared thermal imager being used only during the period when the ambient temperature difference is more obvious. After the scanned image is transmitted to the host through the wire, the convolutional neural network can perform feature analysis and extraction on the image, and after processing, the result can be displayed in real time on the display surface connected by the wire as required.

[0017] The present invention provides a wall defect detection device for evaluating the wall of a high-rise building. It has the following beneficial effects:

[0018] 1. The present invention can actively scan the wall in the vertical direction through the setting of the driving mechanism, and can adjust the vertical movement range according to the height of the wall, so as to be suitable for defect detection of walls of different heights, avoiding the need to prepare multiple accessories required for lifting, thereby preventing the accessories from being worn due to frequent assembly and disassembly, thereby preventing the stability of the infrared thermal imager during movement and its imaging effect, and also preventing the need to increase the scanning range by increasing the distance from the wall, further avoiding unclear imaging when the distance is far, in addition, the movement of each component is simple and reliable, less affected by the environment inside the delivered building, and not prone to failure.

[0019] 2. The present invention can cooperate with the lifting and lowering of the driving mechanism through the setting of the cleaning mechanism to sweep the dust attached to the wall surface, and can enhance the sweeping effect by changing the wind direction. At the same time, the dust in the air can be collected to prevent the buildings delivered for acceptance from being affected by excessive dust and affecting the use of infrared thermal imagers. In addition, water can be used to absorb heat from the air, thereby accelerating the cooling of the wall surface by the air, ensuring that the wall surface can have an obvious temperature gradient.

[0020] 3. The present invention can assist in limiting the distance between the infrared thermal imager and the wall by setting a guiding mechanism, thereby preventing the slider and the connecting rod from needing to readjust their positions due to a change in the distance.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 6 The embodiment of the present invention provides a wall defect detection device for evaluating a wall of a high-rise building, comprising an L-shaped support frame 1, a driving mechanism 2 is arranged at the rear end of the L-shaped support frame 1, a cleaning mechanism 3 is arranged inside the driving mechanism 2, and a guiding mechanism 4 is arranged at the front of the bottom end of the L-shaped support frame 1;

[0034] The driving mechanism 2 includes a servo motor 201, the front end of which is fixedly connected to the middle part of the rear end of the L-shaped support frame 1, the output end of the servo motor 201 passes through the L-shaped support frame 1 and is fixedly connected to a turntable 202, the lower front end of the turntable 202 is fixedly connected to a fixing frame 203, the inside of the fixing frame 203 is rotatably connected to a threaded rod 204, the outer side of the threaded rod 204 is threadedly connected to a slider 205, the front end of the slider 205 is fixedly connected to a connecting rod 206, the outer side of the connecting rod 206 is rotatably connected to a connecting plate 207, the upper inner part of the connecting plate 207 is rotatably connected to a rotating rod 208, the outer front part of the rotating rod 208 is rotatably connected to a vertical plate 209, the bottom end of the vertical plate 209 is fixedly connected to a horizontal plate 210, and the middle part of the top of the horizontal plate 210 is fixedly connected to an infrared thermal imager 211.

[0035] The turntable 202 can be rotated by the servo motor 201, and then the threaded rod 204, the slider 205, and the connecting rod 206 can be rotated synchronously by using the fixing frame 203. Since the connecting rod 206 is connected to the rotating rod 208 through the connecting plate 207, the connecting plate 207 can swing under the restriction of the rotating rod 208 and related components to push the rotating rod 208 to move up and down. As the rotating rod 208 moves, the vertical plate 209 connected thereto can drive the infrared thermal imager 211 to move accordingly through the horizontal plate 210, so as to achieve the purpose of enabling the infrared thermal imager 211 to scan the wall surface in the vertical direction by itself. At the same time, by rotating the threaded rod 204, the slider 205 can drive the connecting rod 206 to move along the threaded rod 204 from the middle area of ​​the turntable 202 to the edge area. At this time, as the turntable 202 rotates again, the connecting rod 206 with the adjusted position can increase the upward movement of the connecting plate 207 The maximum height when the infrared thermal imager 211 is moved can be achieved, and then the infrared thermal imager 211 can scan a higher area through the rotating rod 208, the vertical plate 209, and the horizontal plate 210, so as to meet the detection needs of walls of different heights, avoid the need to increase the scanning range of the infrared thermal imager 211 by moving it away from the wall, and thus prevent some defects from being undetected due to the long distance. At the same time, there is no need to add relevant lifting accessories on site, and prevent the infrared thermal imager 211 from shaking during movement due to wear of the lifting accessories that are frequently assembled, disassembled, and carried. Further, the image scanned by the infrared thermal imager 211 can be prevented from being distorted and twisted. In addition, the motion transmission between the turntable 202, the threaded rod 204, the connecting rod 206, the rotating rod 208 and other components is simple and reliable, and is less affected by the dust and other factors in the acceptance building, with a low failure rate, and the rotation speed of the servo motor 201 is relatively low, so as to ensure that the infrared thermal imager 211 can fully scan the wall.

[0036] Please see attached Figure 3 and attached Figure 6 The bottom end of the threaded rod 204 is fixedly connected to a connecting rod 212 , and the bottom end of the connecting rod 212 passes through the fixing frame 1 203 . Both sides of the slider 205 are slidably connected to both sides of the fixing frame 1 203 .

[0037] The threaded rod 204 can be easily driven to rotate inside the fixing frame 203 by the connecting rod 212, and the fixing frame 203 can be used to guide the slider 205 to prevent the slider 205 from rotating when affected by the threaded rod 204 and failing to drive the connecting rod 206 to move along the threaded rod 204 normally.

[0038] Please see attached Figure 6 and attached Figure 7A cross plate 213 is slidably connected to the upper inner part of the threaded rod 204, the top of the cross plate 213 penetrates the fixed frame 203 and is fixedly connected to a slide plate 214, the top of the slide plate 214 is fixedly connected to a spring 215, the top of the spring 215 is fixedly connected to a U-shaped frame 216, both sides of the bottom end of the U-shaped frame 216 are fixedly connected to the top of the fixed frame 203, and the outer side of the slide plate 214 is slidably connected to the inside of both sides of the U-shaped frame 216.

[0039] The U-shaped frame 216 can provide support for the spring 215, and then the elastic force of the spring 215 can be used to enable the slide plate 214 to push the cross plate 213 from the groove reserved on the surface of the fixed frame 203 into the corresponding cross-shaped cavity inside the threaded rod 204, so as to lock the threaded rod 204 and prevent the threaded rod 204 from rotating under the force when the turntable 202 drives the fixed frame 203 and the threaded rod 204 to rotate. At the same time, in conjunction with the U-shaped frame 216, the cross plate 213 can be further limited in the horizontal direction by the slide plate 214.

[0040] Please see attached Figure 4 and attached Figure 5 The four corners of the bottom end of the horizontal plate 210 are fixedly connected with hollow cylinders 217, and the outer sides of the multiple hollow cylinders 217 are slidably connected with guide cylinders 218, and the bottom ends of the multiple guide cylinders 218 are fixedly connected to the bottom end of the L-shaped support frame 1.

[0041] The hollow tube 217 and the guide tube 218 can limit the movement direction of the horizontal plate 210 without significantly increasing the gravity on the vertical plate 209 and the horizontal plate 210, thereby preventing the horizontal plate 210 from deflecting during movement and affecting the scanning effect of the infrared thermal imager 211, thereby preventing the vertical plate 209 and the rotating rod 208 from shaking in the horizontal direction and affecting the restriction on the connecting plate 207.

[0042] Please see attached Figure 5 The rear end of the turntable 202 is rotatably connected to the rear end of the L-shaped support frame 1, and both sides of the vertical plate 209 are fixedly connected with inclined plates 219, and the bottom ends of the inclined plates 219 on both sides are fixedly connected to the top of the horizontal plate 210.

[0043] The L-shaped support frame 1 can limit the turntable 202 to prevent displacement, and the inclined plate 219 can increase the contact area between the vertical plate 209 and the horizontal plate 210, thereby dispersing the force on the contact part between the vertical plate 209 and the horizontal plate 210.

[0044] Please see attached Figure 2 , Attachment Figure 3 and attached Figure 5A host 220 is fixedly connected to the middle of the bottom end of the L-shaped support frame 1, a display screen 221 is fixedly connected to the upper rear end of the L-shaped support frame 1, a U-shaped frame 222 is fixedly connected to the bottom end of the display screen 221, a front end of the U-shaped frame 222 is fixedly connected to the rear end of the L-shaped support frame 1, and a servo motor 1 201 is arranged inside the U-shaped frame 222.

[0045] The host 220 can process the image transmitted by the wire after being scanned by the infrared thermal imager 211, and then use the convolutional neural network to analyze each scanned image, and through multi-layer convolution, pooling, activation and other operations, efficiently extract and capture the feature information in the images at different levels, and further transmit the processing results to the display screen 221 by the wire for timely display, and use the U-shaped frame 222 to separate the servo motor 1 201 and the display screen 221, and can cooperate with the L-shaped support frame 1 to fix the display screen 221.

[0046] Please see attached Figure 1 , Attachment Figure 4 , Attachment Figure 8 and attached Fig. 9 The cleaning mechanism 3 includes an air inlet bin 301, the top of the air inlet bin 301 is fixedly connected to the front of the bottom end of the horizontal plate 210, and a servo motor 2 302 is fixedly connected to the rear end of the air inlet bin 301. The output end of the servo motor 2 302 passes through the air inlet bin 301 and is fixedly connected to a transmission rod 303. The outer rear part of the transmission rod 303 is fixedly connected to an impeller 1 304. Both sides of the top of the horizontal plate 210 are fixedly connected to connecting seats 305, and the tops of the connecting seats 305 on both sides are slidably connected to air outlet bins 306. The rear ends of the air outlet bins 306 on both sides are fixedly connected to rubber tubes 307, and the ends of the rubber tubes 307 on both sides are far away from the air outlet bins 306 and are respectively fixedly connected to the two sides of the rear end of the air inlet bin 301. The front of the air outlet bins 306 on both sides is fixed A second fixing frame 308 is fixedly connected, and multiple blades 309 are rotatably connected inside the second fixing frames 308 on both sides, connecting pipes 310 are fixedly connected to the rear ends of the air outlet bins 306 on both sides, and air guide pipes 311 are fixedly connected to the bottom ends of the connecting pipes 310 on both sides. The front ends of the air guide pipes 311 on both sides are fixedly connected to hollow bins 312, and impellers 313 are rotatably connected inside the hollow bins 312 on both sides. The middle parts of the second impellers 313 on both sides are fixedly connected to rotating rods 314, and both ends of the second rotating rods 314 on both sides penetrate the hollow bins 312 and are fixedly connected to cams 315, and the top ends of the multiple cams 315 are abutted against T-shaped plates 316, and the front ends of the T-shaped plates 316 are rotatably connected to the two sides of the rear ends of the blades 309 on both sides.

[0047] The servo motor 302 can drive the transmission rod 303 and the impeller 304 to rotate, so that the outside air can be sucked into the air inlet bin 301, and the air can be transferred to the connecting pipe 310 by using the rubber tube 307 with a certain flexibility. At this time, most of the air can directly enter the air outlet bin 306 through the connecting pipe 310, and sweep the wall when discharged from the air outlet bin 306, while a small amount of air can enter the hollow bin 312 through the air guide tube 311, and then enter the air outlet bin 306 after passing through the hollow bin 312 and merge with other air. In addition, since there is an impeller 313 inside the hollow bin 312, the impeller 313 can drive the rotating rod 314 to rotate under the push of the air, so that the cam 315 can rotate synchronously to apply an upward thrust to the T-shaped plate 316. As the T-shaped plate 316 moves upward, it can drive the evenly distributed blades 309 around their respective connections with the fixing frame 308 in cooperation with the fixing frame 308. 8 is rotated at a certain angle, and when the cam 315 continues to rotate, as its protruding part is out of contact with the T-shaped plate 316, the T-shaped plate 316 can drive each blade 309 to return to the initial position under the action of gravity. Therefore, the reciprocating swing of the blade 309 can continuously change the sweeping direction of the air when it is discharged from the air outlet bin 306, and then the sweeping effect on the entire wall surface can be enhanced with the up and down movement of the horizontal plate 210. At the same time, the flow of air can accelerate the temperature loss of the wall surface, thereby destroying the heat balance of the wall and transferring the internal heat to the low temperature area, so that the subsequent infrared thermal imager 211 can find potential abnormal temperature change areas, avoid the infrared thermal imager 211 only being used during the period when the ambient temperature changes significantly, and increase the working period of the infrared thermal imager 211. In addition, after cleaning and cooling, the air outlet bin 306 can be moved backward along the connecting seat 305 to avoid the air outlet bin 306 blocking the scanning range of the infrared thermal imager 211.

[0048] Please see attached Fig. 9 The rubber tubes 307 on both sides are directly opposite to the connecting tubes 310, and the connecting tubes 310 on both sides are fixedly connected with retaining rings 317, the bottom ends of the hollow bins 312 on both sides are fixedly connected with brackets 318, and the bottom ends of the brackets 318 on both sides are fixedly connected to the bottom ends of the air outlet bins 306, and multiple cams 315 are rotatably connected with positioning rods 319 at one end close to the air outlet bin 306, and the positioning rods 319 are rotatably connected to the two sides of the air outlet bin 306 at one end away from the cams 315. The rear parts of the air outlet bins 306 on both sides are slidably connected with limiting plates 320, and the front ends of the limiting plates 320 on both sides are fixedly connected to the rear ends of the T-shaped plates 316.

[0049] The connecting tube 310 facing the rubber tube 307 can ensure that air can enter the air outlet bin 306 normally, and the retaining ring 317 can block the air to a certain extent to ensure that enough air enters the air guide pipe 311 and the hollow bin 312. The bracket 318 and the positioning rod 319 can respectively fix the hollow bin 312 and the cam 315 to ensure that the impeller 313 can drive the cam 315 to rotate stably through the rotating rod 314. Similarly, the T-shaped plate 316 can be limited by the cooperation of the limiting plate 320 and the air outlet bin 306 to prevent the T-shaped plate 316 from shaking when it is acted upon by the cam 315.

[0050] Please see attached Figure 4 and attached Figure 8 A partition frame 321 is fixedly connected to the lower part of the air intake bin 301, the front end of the transmission rod 303 passes through the orifice plate 323 and is fixedly connected to a scraper 322, the bottom end of the orifice plate 323 is fixedly connected to the front end of the top of the partition frame 321, the top of the orifice plate 323 is fixedly connected to the top of the air intake bin 301, and the rear end of the scraper 322 is rotatably connected to the front end of the orifice plate 323.

[0051] The partition frame 321 can be used to separate the upper area of ​​the air inlet bin 301 where the impeller 304 is located from the lower area of ​​the air inlet bin 301, and the orifice plate 323 made of hydrophobic material can be fixed with the cooperation of the air inlet bin 301, so that the orifice plate 323 can be used to filter the air entering the air inlet bin 301 under the action of the impeller 304, so as to prevent dust from continuing to enter the air outlet bin 306 through the rubber tube 307 and then being repeatedly blown out. At the same time, a certain amount of water can be injected into the lower part of the air inlet bin 301, wherein the water level needs to be lower than the highest point of the partition frame 321, and as the transmission rod 303 drives The movable scraper 322 rotates along the front end surface of the orifice plate 323 and the partition frame 321. The dust blocked by the orifice plate 323 can be scraped into the water by the scraper 322 to prevent the holes evenly distributed on the surface of the orifice plate 323 from being blocked by dust. In addition, a small amount of water can be applied to the surface of the orifice plate 323 along with the scraper 322. Therefore, the air temperature can be reduced to a certain extent while enhancing the filtering effect. The cooled air can accelerate the reduction of the wall surface temperature after contacting the wall, thereby shortening the waiting time. The orifice plate 323 can also be used to fix the transmission rod 303 to prevent it from shaking when rotating.

[0052] Please see attached Fig.10 The guiding mechanism 4 includes a guiding frame 401, the bottom end of which is fixedly connected to the front bottom end of the L-shaped supporting frame 1, a sliding frame 402 is slidably connected inside the guiding frame 401, and a disc 403 is rotatably connected to the front of the upper and lower ends of the sliding frame 402. A plurality of through holes 404 are provided on both sides of the sliding frame 402, and limiting rods 405 are slidably connected inside the through holes 404 on both sides, and the limiting rods 405 on both sides penetrate the guiding frame 401 at the ends away from each other.

[0053] The movement direction of the sliding frame 402 can be limited by the guide frame 401. When the limit rod 405 is pulled out of the through hole 404, the sliding frame 402 can drive the disk 403 evenly distributed on its surface to leave the area where the guide frame 401 is located and contact the wall, and then the limit rod 405 can be pushed into another through hole 404 again to lock the position of the sliding frame 402. At this time, the staff only needs to clean, cool and scan the horizontal plate 210 and related parts on its surface in the vertical direction, and then pull the L-shaped support frame 1 to move in the horizontal direction to continue to detect other parts of the wall, so as to prevent the adjusted slider 205 and connecting rod 206 from being unsuitable for the subsequent optimal position due to the change in the distance between the infrared thermal imager 211 and the wall.
