Description

Technical Field

[0001] The present invention relates to the technical field of wall detection equipment, in particular to a high-altitude detection device for thermal defects of thermal insulation walls. Background Art

[0002] Problems during the construction of the insulation wall and the aging of the insulation wall will cause thermal defects in the insulation wall. When thermal defects occur in the insulation wall, the insulation effect of the insulation wall will be poor, affecting the energy efficiency of the building and may even cause safety problems.

[0003] In order to promptly detect thermal defects of insulation walls, infrared imagers are usually used to scan buildings. Infrared imagers receive infrared thermal radiation emitted by insulation walls, and then process it through a series of optical components and photoelectric processing technologies of the thermal imaging system to convert it into a thermal image visible to the human eye. When thermal defects occur in insulation walls, the insulation walls will produce different temperatures, so the thermal images will appear in different colors, allowing people to quickly detect thermal defects in insulation walls. However, the scanning range of infrared imagers is limited, and the scanning angle of the infrared imager needs to be controlled. Therefore, when scanning and detecting high-altitude insulation walls, the scanner is prone to inaccurate detection due to excessive tilt angles. In order to solve this problem, a utility model application with application number CN202221970608.3 was proposed. Provided is a drone-mounted infrared device for accurately detecting exterior wall defects. The utility model uses a drone to send an infrared imager to a high altitude for wall inspection, thereby ensuring the detection accuracy of the infrared imager. When the infrared imager detects the insulation layer at the edge of the window, the metal frame of the window is inconsistent with the insulation layer material, resulting in uneven temperature distribution of the insulation wall, and the window edge is easily affected by the indoor temperature, which may easily lead to misjudgment during detection. According to GB / T39684-2020, the detection range of the outer window area should extend outward by 500mm. At this distance, the drone is close to the wall, and the window edge usually involves protrusions and depressions. These parts are prone to airflow turbulence, thereby increasing the difficulty of operating the drone, and easily causing operational accidents and safety accidents.

[0004] Therefore, in order to reduce the difficulty and accident rate of thermal defect detection of insulation wall at the edge of high-altitude windows, a high-altitude detection device for thermal defects of insulation wall is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-altitude detection device for thermal defects of insulation walls. By arranging an infrared sensor on the support rod and controlling the lifting and lowering of the detection seat and the extension and retraction of the support rod by the extension and retraction of the cable, thermal defects of the insulation wall at the edge of the window can be detected. This method is simple to operate and is less affected by wind during operation, thereby reducing the safety accident rate.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A high-altitude detection device for thermal defects of thermal insulation walls, comprising a winding seat, a winding drum, a detection seat, and a fixed seat, wherein the winding seat is provided with a winding drum, a cable is wound inside the winding drum, the fixed seat is used to connect with the wall, the fixed seat is provided with a pulley, the cable is passed around the pulley and connected to the detection seat, the support rod comprises at least two groups of connecting rod groups, the connecting rod group comprises connecting rod 1 and connecting rod 2, the middle parts of connecting rod 1 and connecting rod 2 are hinged to each other through rotating shaft 1, the connecting rod 1 of the connecting rod group is hinged to the connecting rod 2 of the adjacent connecting rod group through rotating shaft 2, the support rod is divided into movable ends The connecting end, the connecting rod 1 and the connecting rod 2 of the connecting end are both rotatably installed with a slider, the detection seat is provided with a slide groove, the slider is slidably connected to the slide groove, the detection seat is provided with a driving device, the driving device drives the two sliders to slide relative to each other or back to back, a mounting plate is installed on the rotating shaft 1 of the movable end of the support rod, a visual sensor and an infrared sensor are installed on the mounting plate, a nozzle is provided on the mounting plate, a storage box is provided on the detection seat, an air supply device is connected to the storage box, the nozzle is communicated with the storage box, and paint is stored inside the storage box.

[0008] By arranging an infrared sensor on the support rod, the lifting and lowering of the detection seat is controlled by the extension and retraction of the cable, and the position of the infrared sensor is observed by the visual sensor. When the infrared sensor moves to the upper edge of the window, the position of the cable is adjusted, and the infrared sensor can be brought close to the edge of the window for detection. After the infrared sensor is close to the edge of the window, the two sliders are driven to slide relative to each other by the driving device, thereby reducing the angle between the connecting rod one and the connecting rod two, so that the connecting rod one and the connecting rod two swing, and the length of the support rod is increased, thereby realizing the detection of the upper edge of the window. Then, by releasing the cable, the detection seat can be controlled to move up and down, thereby realizing the detection of the vertical direction of the window edge. This scheme is simple to operate by controlling the extension and retraction of the cable and the support rod, and is less affected by wind force, thereby reducing the safety accident rate. Through the extension and retraction setting of the support rod, the volume of the device can be reduced, the wind resistance can be reduced, and the influence of wind force can be further reduced when controlling the extension and retraction of the cable.

[0009] Preferably, the number of support rods is 4, two of which are transverse support rods, and the other two are longitudinal support rods. The two transverse support rods and the two longitudinal support rods are symmetrically arranged on both sides of the detection seat. The connecting rod group of the transverse support rods is arranged in the horizontal direction, and the connecting rod group of the longitudinal support rods is arranged in the vertical direction. A roller is rotatably installed on the mounting plate.

[0010] By setting up transverse support rods, when inspecting windows with insulation layers on all sides, the two transverse support rods are stretched to both sides to complete the inspection of the upper edge of the window. After the transverse support rods are fully stretched, the two support rods can be used to support the inspection seat in the horizontal direction. At this time, the cable is released to complete the inspection of the vertical edge of the window, and the stability of the movement of the released cable inspection seat is guaranteed, thereby improving the inspection accuracy. By retracting the transverse support rods, the inspection of the lower edge of the window can be completed, thereby completing the inspection of this type of window. When inspecting protruding windows such as bay windows, the protruding side does not have an insulation layer, and the depth of the recessed window is shallow. At this time, the longitudinal support rods are controlled to extend so that the rollers of the transverse support rods and the longitudinal support rods abut against the upper and lower sides of the window, thereby avoiding the rollers from detaching from the recessed part of the window during the extension and retraction of the transverse support rods and affecting the normal inspection of the detection device.

[0011] Preferably, a rotating shaft three is rotatably installed on the mounting plate of the transverse support rod, and a mounting rod one and a mounting rod two are provided at both ends of the rotating shaft three. The mounting rod one and the mounting rod two are eccentrically connected to the rotating shaft three and are respectively located on both sides of the rotating shaft three. The roller is rotatably connected to the mounting rod one, and the infrared sensor and the visual sensor are installed on the mounting rod two.

[0012] By eccentrically installing the mounting rod 1 and the mounting rod 2 on the rotating shaft 3, when the mounting rod 1 is squeezed by the wall, the mounting rod 1 and the mounting rod 2 can rotate in the same direction, thereby driving the infrared sensor to swing to one side of the wall. In this way, the infrared sensor can detect both the vertical and horizontal surfaces of the wall without the need for manual control, making operation more convenient for staff.

[0013] Preferably, a top plate is elastically and slidingly mounted on the detection seat, and a lever is rotatably mounted on the detection seat, the lever includes a long end and a short end, the length of the long end is 5-10 times the length of the short end, the short end extends to the inside of the sliding groove of the transverse support rod, the long end abuts against the top plate, and a slope 1 obliquely upward along the first direction is provided below the top plate, a guide block is provided on the detection seat, and a slope 2 is provided on the guide block, the slope 2 contacts the mounting plate on the transverse support rod, and the slope 2 is inclined obliquely downward along the first direction.

[0014] Through the setting of the lever, when the support rod retracts and the slider slides back to back, the slider can squeeze the short end to make the lever swing, so that the lever lifts the detection seat, so that the roller leaves the recessed part of the window, thereby avoiding interference when the detection seat is lowered, thereby causing impact to cause the detection device to shake and affect the operation of the staff. Of course, the sliding of the top plate is controlled by the movement of the slider, so no manual control is required, thereby reducing the operating difficulty of the staff and improving work efficiency. The length of the long end is 5-10 times the length of the short end, and the sliding length of the top plate can be increased when the short end swings a small distance. Therefore, when the top plate is not extended, the guide pulley can penetrate into the recessed part of the window, thereby improving the stability of the detection equipment during operation. A slope 1 is provided at the bottom of the top plate, which is inclined upward along the first direction, which can play a guiding role when the detection seat moves downward and encounters a step. The detection base can be moved over the steps due to the directional action. Therefore, when encountering steps during operation, there is no need to adjust the distance between the detection base and the wall, thereby reducing the difficulty of operation and improving the detection efficiency. However, when inspecting windows with detection surfaces on all sides, the rollers on the longitudinal support rod will interfere with the downward movement of the detection base. Therefore, when inspecting such windows, it is necessary to remove the rollers on the longitudinal support rod, which is more complicated to operate and affects the detection efficiency. However, by providing a second inclined plane on the guide block, and the second inclined plane is inclined downward along the first direction, the mounting plate on the longitudinal support rod can slide along the second inclined plane during the contraction process of the longitudinal support rod, so that the mounting plate moves in a direction away from the wall, thereby not interfering with the movement of the detection base. Therefore, there is no need to adjust the distance between the detection base and the wall during operation, and the detection base can also be moved downward, thereby improving the detection efficiency.

[0015] Preferably, the mounting plate is rotatably connected to the rotating shaft 1 of the movable end, and a limiting groove is provided on the mounting plate, the width of the limiting groove is equal to the diameter of the rotating shaft 1, the length of the limiting groove is equal to half the length of the connecting rod 1, and the rotating shaft 1 on the connecting rod group adjacent to the movable end slides in cooperation with the limiting groove.

[0016] The mounting plate is rotatably connected to the rotating shaft 1 at the movable end to limit the freedom of translation of the mounting plate. A limit groove is provided on the mounting plate, and the rotating shaft 1 on the connecting rod group adjacent to the movable end slides with the limit groove, thereby limiting the rotational freedom of the mounting plate. During the extension and retraction process of the support rod, the horizontal height of the rotating shaft 1 of the transverse support rod remains unchanged, and the horizontal distance of the rotating shaft 1 of the longitudinal support rod remains unchanged. Therefore, the mounting plate will only move in the vertical direction or the horizontal direction, thereby making the movement of the infrared sensor more stable, thereby ensuring the accuracy of detection.

[0017] Preferably, a rubber layer is provided on the roller, and a 1 / 4 cylindrical arc surface is provided on the rubber layer, and the arc surface is bent obliquely upward along the first direction.

[0018] The provision of the rubber layer can increase the friction between the roller and the wall, thereby preventing the detection base from being separated from the window recess due to gravity and causing a safety accident. A 1 / 4 cylindrical arc surface is provided on the rubber layer, and the arc surface is obliquely bent upward along a first direction. When the roller rolls, the wall can generate friction on the roller toward the wall side, thereby pulling the detection base to move toward the wall side, thereby further preventing the detection base from being separated from the window recess due to gravity and causing a safety accident, thereby improving safety during operation.

[0019] Preferably, the driving device includes screw 1 and screw 2, the two ends of screw 1 are provided with threads with opposite rotation directions, the two ends and the middle part of screw 2 are provided with threads, and the threads at both ends and the middle part have opposite rotation directions, the threads at both ends of screw 1 are respectively threadedly connected to the two sliders of the transverse support rod, the threads at both ends of screw 2 are respectively threadedly connected to the sliders of the two transverse support rods away from screw 2, the threads in the middle part of screw 2 are threadedly connected to the sliders of the two transverse support rods close to screw 2, and motor 1 and motor 2 are provided in the middle part of the detection seat, the motor 1 is connected to screw 1, and the motor 2 is connected to screw 2 through a worm gear.

[0020] By driving the transverse support rod and the longitudinal support rod to extend and retract through screw one and screw two, and driving motor two through a worm gear, the setting of the power components can be reduced and the power components can be symmetrically arranged on the detection seat, thereby avoiding the deviation of the center of gravity of the detection seat and causing shaking during movement, thereby reducing the operating difficulty of the detection device and improving the safety of the operation of the detection device.

[0021] Preferably, the bottom of the fixing seat is U-shaped, the U-shaped part of the fixing seat is threadedly connected to a clamping screw, a clamping plate is provided on the clamping screw, an adjusting rod is connected to the fixing seat by bolts, the pulley includes pulley one and pulley two, the pulley one is connected to the fixing seat, the pulley two is connected to the adjusting rod, a detection ring is provided on the adjusting rod, and pressure sensors are provided on both sides of the detection ring.

[0022] By rotating the clamping screw, the fixing seat can be fixed on the fence on the roof, and by installing the adjusting rod with a bolt, the inclination angle of the cable can be adjusted so that the detection seat can be close to the wall without shaking during the lifting process. The setting of the detection ring can determine the force condition and inclination angle of the cable through the contact between the cable and the pressure sensor. When detecting windows with detection surfaces on all sides, it can be determined whether the detection seat is located on the symmetrical axis of the window, so as to avoid the detection seat being rotated along the contact point on one side due to wind force after the horizontal support rod on one side contacts the edge of the window, resulting in shaking during detection and affecting the detection of the detection device.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting an infrared sensor on the support rod and controlling the lifting and lowering of the detection seat and the extension and retraction of the support rod through the extension and retraction of the cable, thermal defects of the insulation wall at the edge of the window can be detected. Therefore, the operation is simple and the influence of wind force is small, thereby reducing the safety accident rate. The extension and retraction of the support rod can reduce the volume of the detection device, reduce wind resistance, and further reduce the influence of wind force.

[0025] 2. By symmetrically arranging the transverse support rods, the transverse support rods are in contact with both sides of the window when they are extended, thereby improving the stability of the detection seat when it is lowered, thereby improving the stability of the detection device and ensuring the detection accuracy. The extension and retraction of the longitudinal support rods can also support the detection seat, avoiding the problem that when the detection device detects the edge of a window with a shallow recessed depth, the roller will be separated from the recessed part when the transverse support rod is extended and retracted, resulting in unstable movement of the infrared sensor during the extension and retraction of the support rod, affecting the detection accuracy of the detection device.

[0026] 3. By eccentrically installing the mounting rod 1 and the mounting rod 2 on the rotating shaft 3, when the mounting rod 1 is squeezed by the wall, the mounting rod 1 and the mounting rod 2 can rotate in the same direction, thereby driving the infrared sensor to swing to one side of the wall. In this way, the infrared sensor can detect both the vertical and horizontal surfaces of the wall without manual control, making it more convenient for staff to operate and improving the efficiency of the detection operation.

[0039] See Figures 1 to 11 The present invention provides a high-altitude detection device for thermal defects of thermal insulation walls, and the technical solution is as follows:

[0040] A high-altitude detection device for thermal defects of thermal insulation walls, including a winding seat and a fixed seat 2, a winding drum is rotatably installed on the winding seat, and a servo motor for driving the winding drum to rotate is provided on the winding seat. The winding drum reels the cable 3, which is a common winding device in the prior art, such as the winding of the elevator cable 3. The lower part of the fixed seat 2 is set to a U shape, and the fixed seat 2 is threadedly connected to a clamping screw 24 at the U-shaped part, and a splint 25 is threadedly connected to the clamping screw 24. The installation of the fixed seat 2 can be completed by clamping the U-shaped part of the fixed seat 2 on the guardrail and then rotating the clamping screw 24. The cable 3 is wound on the winding drum, and a pulley 4 is provided on the fixed seat 2. The cable 3 passes around the pulley 4 and is connected to the detection seat 1. Support rods 6 are provided at both ends of the detection seat 1. The support rods 6 The present invention comprises a plurality of connecting rod groups 63, wherein the plurality of connecting rod groups 63 are divided into connecting rod 1 631 and connecting rod 2 632, wherein the middle parts of connecting rod 1 631 and connecting rod 2 632 are hinged to each other through rotating shaft 1 633, and connecting rod 1 631 of connecting rod group 63 is hinged to connecting rod 2 632 of adjacent connecting rod group 63 through rotating shaft 2 634, and connecting rod 1 631 and connecting rod 2 632 at one end of support rod 6 are both provided with sliders 9, and rotating shaft 1 633 on connecting rod group 63 at the other end is provided with mounting plate 10, one end of support rod 6 provided with mounting plate 10 is movable end 64, and one end provided with slider 9 is connecting end 65, and a slide groove 8 is provided on detection seat 1, and slider 9 is slidably installed in the slide groove 8, and visual sensor 11 and infrared sensor 12 are provided on mounting plate 10, and detection seat 1 is provided with A driving device 7 is provided on it; after the fixing seat 2 is fixed, the cable 3 is released by the servo motor to control the detection seat 1 to descend. By descending the detection seat 1, the side of the window in the vertical direction can be scanned, and the slider 9 of the driving device 7 slides, thereby reducing the angle between the connecting rod 1 631 and the connecting rod 2 632, so that the connecting rod 1 631 and the connecting rod 2 632 swing, and the length of the support rod 6 is increased, thereby realizing the detection of the upper edge of the window, and the infrared sensor 12 moves in the horizontal direction, thereby realizing the horizontal detection of the window edge. The scheme is simple to operate by controlling the extension and contraction of the cable 3 and the extension and contraction of the control support rod 6, and is less affected by wind force, thereby reducing the safety accident rate, and through the support rod 6 The telescopic setting can reduce the volume of the device and reduce wind resistance when the control cable 3 is extended or retracted, further reduce the impact of wind force, and improve completeness; a nozzle 13 is provided on the mounting plate 10, and a storage box 14 is provided on the detection seat 1. The storage box 14 is connected to an air supply device, and the air supply device includes a compressed gas tank and a control switch. The compressed gas tank is connected to the storage box 14 through a pipeline, and a control switch is provided on the pipeline. The nozzle 13 is connected to the storage box 14, and paint is stored in the storage box 14; when a defective part is detected, the control switch is turned on to allow compressed gas to enter the storage box 14. At this time, the air pressure inside the storage box 14 increases to squeeze the paint, so that the paint is sprayed on the defective part, so that the staff can record the position of the defective part for subsequent maintenance.There are 4 support rods 6, two of which are transverse support rods 61, and the other two are longitudinal support rods 62. The two transverse support rods 61 and the two longitudinal support rods 62 are symmetrically arranged on both sides of the detection seat 1. The connecting rod group 63 of the transverse support rod 61 is arranged in the horizontal direction, and the connecting rod group 63 of the longitudinal support rod 62 is arranged in the vertical direction. When the transverse support rod 61 is extended and retracted, the upper and lower edges of the window can be detected. After the transverse support rod 61 is opened and abutted against the wall, the detection seat 1 is supported horizontally by the two support rods 6. At this time, the cable 3 is released to complete the detection of the vertical edge of the window, and the stability of the movement of the detection seat 1 after releasing the cable 3 can be guaranteed. When the window is convex, the convex side does not have an insulation layer, and the depth of the recessed window is shallow. At this time, the longitudinal support rod 62 is controlled to extend so that the transverse support rod 61 and the longitudinal support rod 62 are in contact with the upper and lower sides of the window, so as to avoid the transverse support rod 61 from being separated from the recessed part of the window during the extension and contraction process, thereby affecting the normal detection of the detection device, thereby improving the detection accuracy. A roller 15 is rotatably installed on the mounting plate 10 to reduce the resistance encountered by the support rod 6 during extension and contraction; a rubber layer 22 is provided on the roller 15, and a 1 / 4 cylindrical arc surface 23 is provided on the rubber layer 22, and the arc surface 23 is bent obliquely upward along a first direction, and the first direction is the direction of the detection seat 1 toward the wall side, which is represented by S in the figure; through the setting of the rubber layer 22 , which can increase the friction between the roller 15 and the wall, thereby preventing the detection seat 1 from being separated from the window recess due to gravity and causing a safety accident; a 1 / 4 cylindrical arc surface 23 is provided on the rubber layer 22, and the arc surface 23 is bent obliquely upward along the first direction, so that when the roller 15 rolls, the wall can generate friction on the roller 15 toward the side of the wall, thereby pulling the detection seat 1 to move toward the side of the wall, thereby further preventing the detection seat 1 from being separated from the window recess due to gravity and causing a safety accident, thereby improving safety during operation; a rotating shaft 3 16 is rotatably installed on the mounting plate 10 of the horizontal support rod 61, and a mounting rod 1 17 and a mounting rod 2 18 are provided at both ends of the rotating shaft 16, and the mounting rod 1 17 and the mounting rod 2 18 are connected to the rotating shaft 3 1 6 is eccentrically connected and is respectively located on both sides of the rotating shaft 3 16, the roller 15 is rotatably connected to the mounting rod 17, and the infrared sensor 12 and the visual sensor 11 are installed on the mounting rod 2 18; because the mounting rod 17 and the mounting rod 2 18 are eccentrically arranged on the rotating shaft 3 16 and are respectively located on both sides of the rotating shaft 3 16, when the mounting rod 17 is squeezed, the mounting rod 17 drives the rotating shaft 3 16 to rotate, thereby driving the mounting rod 2 18 to swing to the other side, and the mounting rod 17 is always located inside the window recess, so that the infrared sensor 12 swings to the outer edge of the window, so that the infrared sensor 12 can detect both the vertical and horizontal surfaces of the wall without manual control, making operation more convenient for the staff;The fixing seat 2 is connected with an adjusting rod 26 by bolts, and the sliding includes a pulley 1 41 and a pulley 2 42. The pulley 1 41 is connected to the fixing seat 2, and the pulley 2 42 is connected to the adjusting rod 26. A detection ring 27 is provided on the adjusting rod 26, and a pressure sensor 28 is provided on the inner wall of the detection ring 27 facing the opposite direction of the first direction. When in use, the fixing bolts of the adjusting rod 26 can be removed and the angle of the adjusting rod 26 can be changed by rotating the adjusting rod 26, so that the detection seat 1 can move in contact with the wall to ensure the stability of the movement of the detection seat 1. When the two horizontal support rods 61 are extended and retracted at the same time, and only one side is in contact with the inner wall of the window, The wind on the other side causes torque on the detection base 1, causing it to shake and affect detection. When only one side of the detection base 1 is in contact with the side of the window, the transverse support rod 61 is further extended and retracted. The cable 3 now follows the horizontal movement of the detection base 1, causing the cable 3 to tilt and squeeze the pressure sensor 28 on the side wall of the detection ring 27. When the visual sensor 11 observes that the infrared sensor 12 has moved to the other side of the window, the extension of the support rod 6 is stopped. The fixed base 2 can then be moved so that the cable 3 no longer squeezes the pressure sensor 28, thereby preventing the detection base 1 from being affected by the wind and affecting the normal detection of the insulation layer.

[0041] The mounting plate 10 is rotatably connected to the rotating shaft 1633 of the movable end 64, and a limiting groove 21 is provided on the mounting plate 10. The width of the limiting groove 21 is equal to the diameter of the rotating shaft 1633, and the length of the limiting groove 21 is equal to half the length of the connecting rod 1631. The rotating shaft 1633 on the connecting rod group 63 adjacent to the movable end 64 slides with the limiting groove 21. The mounting plate 10 is rotatably connected to the rotating shaft 1633 of the movable end 64 to limit the freedom of translation of the mounting plate 10. By providing the limiting groove 21 on the mounting plate 10, and the rotating shaft 1633 on the connecting rod group 63 adjacent to the movable end 64 slides with the limiting groove 21, thereby limiting the freedom of translation of the mounting plate 10. The rotational freedom of the mounting plate 10 is controlled, and during the extension and retraction process of the support rod 6, the horizontal height of the rotation axis 633 of the transverse support rod 61 remains unchanged, and the horizontal distance of the rotation axis 633 of the longitudinal support rod 62 remains unchanged. Therefore, the mounting plate 10 will only move in the vertical direction over the horizontal direction, so that the movement of the infrared sensor 12 is more stable, thereby ensuring the accuracy of the detection; a top plate 19 is elastically and slidably mounted on the detection base 1, and a lever 20 is rotatably mounted on the detection base 1. The lever 20 includes a long end 201 and a short end 202. The length of the long end 201 is 50 times the length of the short end 202, and the short end 202 extends to the transverse support Inside the slide groove 8 where the rod 61 slides, the long end 201 abuts against the top plate 19, and a slope 191 obliquely upward in the first direction is provided below the top plate 19; when the support rod 6 contracts and the slider 9 slides back to back, the slider 9 can squeeze the short end 202 to make the lever 20 swing, so that the lever 20 lifts the detection seat 1, thereby preventing the roller 15 from being located inside the recessed part of the window, thereby causing interference when the detection seat 1 descends, thereby causing a collision and causing the detection device to shake and affect the operation of the staff. Of course, the sliding of the top plate 19 is controlled by the movement of the slider 9, so no manual control is required, thereby reducing the difficulty of operation for the staff. The length of the long end 201 is 5 times that of the short end 202, which can increase the sliding length of the top plate 19 when the short end 202 swings a small distance. Therefore, when the top plate 19 is not extended, the guide pulley 4 can penetrate into the recessed part of the window, thereby improving the stability of the detection equipment during operation; a slope 191 is provided below the top plate 19, which is inclined upward along the first direction. When the detection base 1 moves downward and encounters a step, it plays a guiding role, allowing the detection base 1 to move over the step. Therefore, when encountering a step during operation, there is no need to adjust the distance between the detection base 1 and the wall, thereby reducing the difficulty of operation and improving the detection efficiency.When inspecting a window with inspection surfaces on all sides, the roller 15 on the longitudinal support rod 62 will interfere with the downward movement of the inspection seat 1. Therefore, when inspecting such a window, it is necessary to remove the roller 15 on the longitudinal support rod 62, which is more complicated to operate and affects the inspection efficiency. By providing a slope 25 on the guide block 29, and the slope 25 is inclined downward along the first direction, the mounting plate 10 on the longitudinal support rod 62 can slide along the slope 25 during the contraction process of the longitudinal support rod 62, so that the mounting plate 10 can move in the direction away from the wall, thereby not interfering with the movement of the inspection seat 1. Therefore, during operation, there is no need to adjust the distance between the inspection seat 1 and the wall, and the downward movement of the inspection seat 1 can be achieved, thereby improving the inspection efficiency; the driving device 7 includes a screw rod 1 71 and a screw rod 2 72, and the two ends of the screw rod 1 71 are provided with threads with opposite rotation directions, and the two ends and the middle part of the screw rod 2 72 are provided with threads, and the threads at both ends are opposite to the threads in the middle. The threads at both ends of the screw rod 1 71 are respectively threadedly connected to the two sliders 9 of the transverse support rod 61, and the threads at both ends of the screw rod 2 72 are respectively threadedly connected to the two sliders 9 of the transverse support rod 61, and the threads at both ends of the screw rod 2 The slider 9 is threadedly connected to the two transverse support rods 61 away from the screw rod 2 72, and the thread in the middle of the screw rod 2 72 is threadedly connected to the slider 9 of the two transverse support rods 61 close to the screw rod 2 72. A motor 1 73 and a motor 2 74 are provided in the middle of the detection seat 1. The motor 1 73 is connected to the screw rod 1 71, and the motor 2 74 is connected to the screw rod 2 72 through a worm gear 75. When the motor 1 73 rotates, the screw rod 1 71 rotates in the opposite direction, thereby controlling the slider 9 to slide relative to or back to back, thereby controlling the transverse support rod 61. The motor 2 74 rotates, transmitting power to the screw 2 72 via the worm gear 75. The threads at both ends of the screw 2 72 rotate in opposite directions to the threads in the middle. As the screw rotates, the two sliders 9 are controlled to slide toward or away from each other, thereby achieving telescopic control of the longitudinal support rod 62. Both the motor 1 73 and the motor 2 74 are located in the middle of the detection base 1, thereby preventing the detection base 1 from shifting its center of gravity and causing shaking during movement, thereby reducing the difficulty of operating the detection device and improving the safety of the detection device.

[0042] How it works: See Figures 1 to 11 Before the operation, adjust the rotation angle of the adjusting rod 26 and observe the angle of the cable 3. When the angle between the cable 3 and the wall is acute, it can be judged that the detection seat 1 has been attached to the wall, and the wall detection can be carried out at this time.

[0043] When inspecting a window with detection surfaces on all sides, the control cable 3 is released, and the image displayed by the visual sensor 11 is observed. When the visual sensor 11 observes the upper edge of the window, the detection seat 1 swings toward the recessed part of the window under the pulling force of the cable 3, causing the roller 15 to enter the recessed part, and then the cable 3 contracts, causing the roller 15 to fit the upper wall of the window. At this time, the mounting rod 17 is squeezed, driving the rotating shaft 3 16 to rotate, thereby driving the infrared sensor 12 to rotate upward, and then the motor 1 73 is started, driving the screw 1 71 to rotate, causing the two sliders 9 of the transverse support rod 61 to slide relative to each other, thereby extending the transverse support rod 61, thereby detecting the upper edge of the window; during the movement, when the visual sensors 11 on both sides observe that the roller 15 moves to the side edge of the window, check whether the pressure sensor 28 generates a signal. If a signal is generated, readjust the fixing seat 2 until the pressure sensor 28 no longer generates an electrical signal. After the adjustment is completed, the control cable 3 is released, and the control The horizontal support rod 61 is extended and retracted, and the extension length is the rotation radius of the mounting rod 17. At this time, the horizontal support rod 61 squeezes the mounting rod 17 again during the extension and retraction process, so that the mounting rod 17 drives the infrared sensor 12 to swing to the side edge of the window. When the cable 3 is released, the detection of the side of the window can be completed. When the visual sensor 11 observes the lower edge of the window, the horizontal support rod 61 is controlled to retract. At this time, the detection of the window can be completed. After the horizontal support rod 61 is fully extended and retracted, the slider 9 squeezes the short end 202 of the lever 20 to make the lever 20 swing, and squeezes the top plate 19 through the long end 201 of the lever 20, so that the top plate 19 pushes the detection seat 1 away from the wall. At this time, the cable 3 is released, and the detection seat 1 can slide down to detect the next window. In this process, the longitudinal support rod 62 is always retracted, so that the longitudinal support rod 62 pulls the mounting plate 10 to slide along the inclined surface 2 5, thereby making the roller 15 on the longitudinal support rod 62 away from the front, and thus will not interfere with the downward movement of the detection seat 1.

[0044] When inspecting a window with inspection surfaces only on the upper and lower sides or on the upper and lower sides and one side, the inspection seat 1 moves downward when the cable 3 is released. When the visual sensor 11 observes the upper edge of the window, the inspection seat 1 swings toward the recessed part of the window under the pulling force of the cable 3, causing the roller 15 to enter the recessed part, and then the cable 3 contracts, causing the roller 15 to fit with the upper wall of the window. At this time, the mounting rod 17 is squeezed, driving the rotating shaft 3 16 to rotate, thereby driving the infrared sensor 12 to rotate upward, and then the motor 2 74 is started, and the screw 2 72 is driven to rotate through the worm gear 75, so that the slider 9 of the longitudinal support rod 62 slides relatively, thereby controlling the length of the longitudinal support rod 62 to extend, so that the roller 15 on the longitudinal support rod 62 abuts against the lower edge of the window, thereby supporting the inspection seat 1. At this time, the horizontal support rod 61 is controlled to extend to complete the inspection of the upper edge of the window. After the inspection is completed, the longitudinal support rod 62 is controlled to retract. After the longitudinal support rod 62 retracts When the cam 1 is released, the roller 15 on the longitudinal support rod 62 will not interfere with the movement of the detection seat 1, and the detection seat 1 can detect the side wall of the window on one side. When it moves to the bottom of the window, the longitudinal support rod 62 extends and begins to retract when the longitudinal support rod 62 is stuck in the direction of the next window. At this time, the longitudinal support rod 62 and the transverse support rod 61 are clamped on the crossbeam between the two windows to ensure the stability of the detection equipment. At this time, the transverse support rod 61 can be retracted to detect the lower edge of the window. After the transverse support rod 61 is fully extended, the slider 9 squeezes the short end 202 of the lever 20 to make the lever 20 swing, and squeezes the top plate 19 through the long end 201 of the lever 20, so that the top plate 19 pushes the detection seat 1 away from the wall. At this time, the cable 3 is released and the detection seat 1 can slide down to detect the next window.
