Description

Technical Field

[0001] This invention relates to the field of building wall inspection technology, specifically to an intelligent detection device for defects in building exterior walls. Background Technology

[0002] Building wall inspection refers to a comprehensive inspection and evaluation of building walls to ensure that their structural integrity, material strength, crack deformation, humidity, sound insulation and heat insulation performance meet relevant standards and specifications. Wall inspection is an important part of building safety assessment, which can promptly detect potential structural problems and ensure the safety of building use and the safety of residents' lives and property.

[0003] Chinese invention patent CN222704438U discloses a wall strength testing device, comprising: a movable plate, a mounting box mounted on the top of the movable plate, a push plate fixedly connected to one side of the top of the movable plate, and a mounting plate mounted on the top of the mounting box. This utility model relates to the technical field of wall strength testing devices. Through the cooperation of a first servo motor, a transmission gear, and a threaded cylinder, the servo motor drives the transmission gear to rotate, causing the threaded cylinder to rotate. The engagement of the threaded cylinder with a threaded rod causes the threaded rod to rise and fall, enabling the mounting plate to move the pressure sensor to the detection position. This solves the problem in existing technologies where an extension rod needs to be installed at the bottom of the mounting frame to reach the pressure sensor, making testing inconvenient.

[0004] Furthermore, this invention solves some detection problems to a certain extent. Through the cooperation of the first servo motor, transmission gears, and threaded cylinder, the pressure sensor can be raised and lowered, facilitating the detection of wall strength at different heights and overcoming the inconvenience of installing extension rods in traditional methods. However, the device's function is relatively limited, focusing solely on wall strength detection. It cannot comprehensively detect various defects such as crack width and depth, internal hollowing, and leakage. Moreover, its detection range and adaptability are significantly insufficient for complex and varied building exterior wall structures, such as irregularly shaped walls and high-rise building exterior walls, making it difficult to meet the diverse detection needs of modern buildings.

[0020] Beneficial effects

[0021] Compared with existing technologies, the present invention provides an intelligent detection device for defects in building exterior walls, which has the following advantages:

[0022] 1. By adjusting the cooperation between the first contact plate, the first limit block and the first contact block in the adjustment assembly, as well as the synergistic effect of the connecting rod, the second limit block and the first torsion spring, the detection device can be height-adjusted according to actual needs. During the detection process, the position of each component can be adjusted by the control device to realize the detection of exterior wall areas at different heights, thus improving the applicability of the device.

[0023] 2. Through the coordinated operation of the adjustment mechanism and the detection mechanism, the exterior walls of buildings can be accurately inspected. The magnetic rod and magnetic block in the detection component work together. When the rotating rod rotates, the detection component can move closer to or away from the wall. By repeatedly striking the wall with the hammer rod, and by sealing the wall with the sealing plate, the sound of the hammering can be completely inserted into the interior of the sealing plate. Then, the detector is used to analyze the impact sound to detect the strength of the wall. It can effectively detect internal defects in the wall. The detection method is flexible and accurate.

[0024] 3. Since both the sliding plate and the rotating rod are electrically connected to the equipment control device, the operator can control the rotation of the rotating rod through the equipment control device, thereby driving a series of actions of the detection components to realize the detection of the wall and the adjustment of the height of the detection device. This reduces manual operation steps, reduces labor intensity, and improves the efficiency of the detection work. Attached Figure Description

The control block 20315 is fixedly connected to the slide plate 30317.

[0046] It should be noted that the two threaded rods 3034 are rotatably connected, and the threads on the two threaded rods 3034 are in opposite directions.

[0047] The following describes the working process and principle of the above embodiments:

[0048] The work steps are as follows:

[0049] The operator controls the rotating rod 301 to rotate inside the fixed frame 2037 via the equipment control device. This causes the rotating rod 301 to drive the transmission wheel 3033 and the magnetic rod 3031 to rotate synchronously. When the magnetic rod 3031 rotates to the same vertical horizontal plane as the magnetic block 3038, the magnetic rod 3031 magnetically attracts the magnetic block 3038 and slides it downwards towards the slot plate 3037. This causes the magnetic block 3038 to stretch the spring 3039, which in turn causes the magnetic block 3038 to drive the locking block 30310 to slide synchronously inside the slot plate 3037. The locking block 30310 then abuts against the sliding groove 30312, causing the sliding groove 30312 to drive the slot plate 20311 to slide away from the wall. This causes the slot plate 20311 to drive the sealing plate 30313 to move synchronously, which in turn drives the detector 30314 to move synchronously, and finally, the sealing plate 30313 drives the fixed plate 3031. 5. Synchronous movement causes the fixed plate 30315 to move synchronously with the knocking rod 30316 until the magnetic rod 3031 rotates to a position where it is no longer magnetically attracted to the magnetic block 3038. At this point, the spring 3039 drives the locking block 30310 to slide into the groove plate 3037 through the magnetic block 3038. The locking block 30310 then contacts the sliding groove 30312, causing the groove plate 30311 to slide into the groove plate 3037. Under the elastic action of the spring 3039, the groove plate 30311 drives the sealing plate 30313 and the knocking rod 30316 to repeatedly impact the wall. This causes the impact sound to enter the interior of the sealing plate 30313, allowing the detector 30314 to identify and analyze the sound inside the sealing plate 30313. The strength of the wall is tested by the repeated impact of the knocking rod 30316, and the impact sound is analyzed by the detector 30314.

[0050] During the rotation of the first conveyor wheel 3033, the first conveyor wheel 3033 drives the threaded rod 3034 and the second conveyor wheel 3035 to rotate synchronously via the conveyor belt 3036. This causes the threaded rod 3034 to drive the threaded sliding plate 30317, which is threaded to it, to move away from the fixed frame 2037. The sliding plate 30317 then drives the first slot plate 3037 and the control block 20315 to move synchronously. When the control block 20315 enters the control slot 20314, the first contact plate 2035 begins to rotate, causing the first contact plate 2035 to rotate. 35 drives the limiting block 2036 to rotate synchronously, causing the limiting block 2036 to abut against the abutment block 2032 on its top during rotation. This causes the limiting block 2036 to flip towards the bottom of the abutment plate 2035, disengaging it from the abutment block 2032. Subsequently, the abutment plate 2035 drives the limiting block 2036 to flip in the opposite direction, causing the bottom end of the limiting block 2036 to abut against the top end of the abutment block 2032 on the top of the abutment plate 2035. This causes the first contact plate 2035 to move the first fixing plate 2034, the first fixing bracket 2033, and the third fixing bracket 2038 upwards simultaneously. This, in turn, causes the third fixing bracket 2038 to move the connecting rod 20310 and the second limiting block 20313 upwards simultaneously via the second fixing plate 2039. This causes the second limiting block 20313 to come into contact with the contact block 2032. Subsequently, the second limiting block 20313 causes the torsion spring 20311 to begin rotating. When the bottom end of the second limiting block 20313 reaches the upper surface of the contact block 2032, the second limiting block 2031... 3. The contact with the upper surface of the contact block 2032 is repeated, and the above movements are performed in sequence. This can raise the detection mechanism 300. By adjusting the cooperation between the contact plate 2035, the limiting block 2036 and the contact block 2032 in the adjustment assembly 202, as well as the synergistic effect of the connecting rod 20310, the limiting block 20313 and the torsion spring 20311, the detection device can be height adjusted according to actual needs. During the detection process, the position of each component can be adjusted by the control device to realize the detection of exterior wall areas at different heights, thus improving the applicability of the device.

[0051] Through the coordinated operation of the adjustment mechanism 200 and the detection mechanism 300, the exterior wall of the building can be accurately inspected. The magnetic rod 3031 and magnetic block 3038 in the detection component 302 cooperate to move the detection component closer to or away from the wall when the rotating rod 301 rotates. By repeatedly striking the wall with the striking rod 30316, and sealing it with the wall through the sealing plate 30313, the sound of the striking can be completely inserted into the interior of the sealing plate 30313. Then, the detector 30314 is used to analyze the impact sound to detect the strength of the wall, which can effectively detect internal defects in the wall. The detection method is flexible and accurate.

[0052] Both the sliding plate 3102 and the rotating rod 301 are electrically connected to the equipment control device. The operator can control the rotation of the rotating rod 301 through the equipment control device, thereby driving a series of actions of the detection component 302 to realize the detection of the wall and the adjustment of the height of the detection device. This reduces manual operation steps, reduces labor intensity, and improves the efficiency of the detection work.
