Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, and in particular to an automatic water spray inspection device for external envelope structures. Background Technology

[0002] The water spray test is a test to check for leaks in building exterior walls, aluminum alloy doors and windows, curtain walls, etc. It is intended to identify leaks in building walls, doors and windows, etc., so that repairs and leaks can be made. Traditional water spray tests use manual pipes to spray water to simulate normal rainwater for detection.

[0003] With the continuous development of prefabricated components, the construction quality inspection of the joint positions has become a focus of attention. However, traditional water spray inspection is not only low in water pressure and large in water consumption, but also poses a great safety risk due to manual pipe laying, and cannot achieve targeted inspection by spraying. Utility Model Content

[0004] The technical problem this utility model aims to solve is: in order to address the issues of low water pressure, high safety risks, large water consumption, and inability to target specific areas in traditional water spraying inspections, this utility model provides an automatic water spraying inspection device for external envelope structures. This device identifies key areas such as cracks and defects at the corners of doors and windows using inspection instruments, and coordinates with a water spraying mechanism to achieve targeted spraying. At the same time, the water spraying mechanism moves along the perimeter of the building via slings, replacing manual pipe laying and improving the safety of the inspection.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an automatic water spray detection device for an outer enclosure structure, including an outer enclosure structure and an outer frame. The outer frame is vertically arranged on the outside of the facade of the outer enclosure structure. Let the side of the outer frame extending vertically be the z-axis, the longer side of the outer frame in the horizontal plane be the x-axis, and the side of the outer frame in the horizontal plane perpendicular to the x-axis be the y-axis. The side of the outer frame extending along the z-axis is longer than the side extending along the x-axis, and the side extending along the x-axis is longer than the side extending along the y-axis. The side of the outer frame close to the outer enclosure structure and located in the xz plane is the front side, and the front side of the outer frame is parallel to the facade of the outer enclosure structure.

[0006] The top floor of the outer enclosure structure is equipped with a sling mechanism, and the top rear side of the outer frame is provided with lugs for mounting the slings; thus, vertical lifting and lowering movement is achieved through the sling mechanism, avoiding the risks of manual pipe laying and improving the safety and efficiency of inspection.

[0007] A protective tube is fixedly installed on the front side of the outer frame, and the protective tube extends along the edge of the front side of the outer frame; several spray heads are installed on the side of the protective tube away from the outer frame; a cavity penetrating the outer frame is opened on the front side of the outer frame, and a mounting frame is movably installed on the inner side of the outer frame, and the mounting frame is located in the cavity; the maximum end face of the mounting frame is parallel to the facade of the outer enclosure structure.

[0008] The maximum end face of the mounting frame is fixedly equipped with a detection instrument, which includes an infrared camera and a visible light camera. The infrared camera and the visible light camera work together to capture the facade image of the external envelope structure.

[0009] Therefore, the mounting frame moves within the cavity, facilitating the scanning of the external envelope by the detection components; the images collected by the infrared and visible light cameras are transmitted to the processing unit, which uses image processing algorithms to automatically identify cracks, corner defects, etc.; based on the obtained data, targeted spray detection can be performed on cracks and corner defects, thereby improving the accuracy of the water spray detection data.

[0010] Furthermore, four support plates are fixedly installed on the inner side of the outer frame, and the support plates are located at the corners of the outer frame; a winding machine is fixedly installed on the rear side of the support plate, and a pulley is fixedly installed on the rear side of the mounting frame. The winding machine corresponds to the pulley and is connected by a cable, and one end of the cable is fixedly connected to the support plate; thus, multiple winding machines control the cable length, and in combination with the pulley, the mounting frame can move freely within the cavity.

[0011] Furthermore, the detection instrument also includes an infrared imaging detector, which is used to detect the temperature distribution on the facade of the external envelope structure. Thus, the infrared imaging detector scans the facade of the external envelope structure, draws its humidity distribution map, selects the part with the highest humidity for indoor inspection, and checks whether there is any water leakage, reducing the time required for personnel to inspect each floor.

[0012] Furthermore, a ranging mechanism is provided on the top of the outer frame. The ranging mechanism includes a moving component and a laser rangefinder. The laser rangefinder is fixedly mounted on the moving component, and the moving component is used to control the laser rangefinder to move back and forth in the x-axis direction. Thus, the outer enclosure size data can be obtained in real time through the laser rangefinder, which facilitates the winding machine to control the movement range of the mounting frame and avoids the detection instrument from obtaining useless data.

[0013] Furthermore, the moving component includes a primary slide rail, a secondary slide rail, and a sliding frame. The bottom of the primary slide rail is fixedly connected to the top of the outer frame. Two secondary slide rails are provided, arranged opposite each other without contact, and arranged back and forth along the y-axis. The side of the secondary slide rail is slidably connected to the inner wall of the primary slide rail. The sliding frame corresponds to each secondary slide rail, and the bottom of the sliding frame is slidably connected to the side wall of the secondary slide rail. The laser rangefinder corresponds to each sliding frame, and the base of the laser rangefinder is fixedly installed on the top of the corresponding sliding frame. Thus, the two laser rangefinders move on the secondary slide rail via the sliding frame, facilitating subsequent measurement.

[0014] Furthermore, the inner wall of the sliding frame and the top of the secondary slide rail form a cavity. The top of the secondary slide rail is provided with a rack, and a rotary motor is fixedly installed on the top of the inner wall of the sliding frame. Both the rotary motor and the rack are located in the cavity. A gear is fixedly installed at the output end of the rotary motor, and the tooth surface of the gear meshes with the rack. Thus, the sliding frame moves by the gear meshing with the rack.

[0015] Furthermore, the outer frame includes at least three telescopic arms, one of which has its long side arranged vertically along the z-axis, and the other has its long side arranged horizontally along the x-axis; one of the horizontally arranged telescopic arms is fixedly installed at one end of the vertically arranged telescopic arm, and the other horizontally arranged telescopic arm is fixedly installed at the other end of the vertically arranged telescopic arm; thus, the outer frame is U-shaped. After the dimensions of the outer enclosure are measured by a laser rangefinder, the telescopic arms extend and retract as needed, thereby changing the area of ​​the front side of the outer frame to adapt to different outer enclosure structures.

[0016] Furthermore, the telescopic arm includes an outer arm and an inner arm sleeved within the outer arm. At least one intermediate arm is sleeved between the outer arm and the inner arm. A gear II is fixedly installed at the bottom of the outer arm and the intermediate arm, and a rotary motor II is provided on one side of the gear II. A rack II is fixedly installed at the bottom of the intermediate arm and the inner arm. The rack II is arranged in a stepped manner in the y-axis direction, and the rack II meshes with the gear II in a one-to-one correspondence. Thus, the rotary motor II controls the rack II to rotate, pushing the intermediate arm and the inner arm to move synchronously, thereby realizing the extension of the telescopic arm.

[0017] Furthermore, the top of the outer section arm, located horizontally at the top, is fixedly connected to the first-stage slide rail. The tops of the middle arm and the inner section arm are provided with pulleys that slide with the first-stage slide rail. A connecting plate is provided at the end of the inner section arm away from the outer section arm, and one end of the connecting plate is fixedly connected to the second-stage slide rail located on the front side. Thus, the moving inner section arm pulls the corresponding second-stage slide rail to move along the x-axis, thereby extending the displacement distance of the laser rangefinder.

[0018] Furthermore, the protective tube includes at least three telescopic sleeves, one of which is vertically arranged along the z-axis and fixedly installed to the outer frame via a fixed flange, and the other two telescopic sleeves are horizontally arranged along the x-axis; one of the horizontally arranged telescopic sleeves is connected to one end of the vertically arranged telescopic sleeve via a corner tube, and the other horizontally arranged telescopic sleeve is connected to the other end of the vertically arranged telescopic sleeve via a corner tube; thus, when the outer frame is expanded, the corresponding protective tube extends accordingly, so that the water spray detection can adapt to different external protective structures.

[0019] Furthermore, the telescopic sleeve includes an outer sleeve, an inner hollow tube, and at least one intermediate tube sleeved between the outer sleeve and the inner hollow tube. The outer sleeve, the inner hollow tube, and the intermediate tube move synchronously together by a synchronous pulley rope mechanism.

[0020] A pulley two is provided at one end of the inner wall of the outer tube and the middle tube, and a pulley three is provided at the other end of the inner wall of the middle tube. A gathering wheel is provided at the other end of the inner wall of the outer tube, and a torsion spring is provided on the inner side of the gathering wheel. The cable end of the gathering wheel passes through pulley two and pulley three at the outer tube and the middle tube in sequence and is fixed to the inner wall of the outer tube. The end of the inner hollow tube located inside the middle tube is fixedly connected to the cable. The outer tube, which is arranged laterally, is fixedly connected to the adjacent outer arm section, and the inner hollow tube, which is arranged laterally, is fixedly connected to the adjacent inner arm section. Thus, when the telescopic arm extends, it pulls the inner hollow tube to move, thereby driving the middle tube to move synchronously.

[0021] Furthermore, the front sides of the outer sleeve, inner hollow tube, and intermediate tube are fixedly connected to the spray heads one by one. The front sides of the inner hollow tube and intermediate tube are provided with placement grooves, the long side of which is set along the x-axis, and one end of the placement groove passes through one end of the corresponding inner hollow tube or intermediate tube. The placement groove and the spray head are located on the same straight line. Thus, when the telescopic sleeve extends or retracts, the distance between the spray heads is dynamically adjusted according to the extension stroke. The placement grooves ensure that the spray heads do not interfere with the movement of the telescopic sleeve.

[0022] Furthermore, a water collection tank is provided below the front side of the outer frame, the rear side of the water collection tank is fixedly connected to the outer section arm of the outer frame, a water collection cavity is provided on the top of the water collection tank, and a scraper is fixedly installed on the front side of the water collection tank, with one end of the scraper contacting the vertical surface of the outer enclosure; thus, the water collection tank can collect the water after spraying into the water collection cavity, avoiding the waste of water resources.

[0023] Furthermore, a water storage tank is fixedly installed on one side of the water collection tank. The input end of the water storage tank is connected to the water collection tank pipeline. A filter is installed inside the water storage tank, and a water pump is installed at the output end of the water storage tank. A water distributor is installed inside a vertically arranged outer sleeve. The output end of the water pump is connected to the water distributor pipeline, and a flow sensor is installed on the pipeline. The output end of the water distributor is connected to a corresponding pipeline of the sprinkler head, and a water pressure sensor is installed on the pipeline. Thus, the water pump delivers water from the water storage tank to the sprinkler head for spraying. After passing through the vertical surface, the water flows back to the water collection chamber, is filtered by the filter, and then enters the water storage tank, thereby realizing the reuse of water resources.

[0024] Furthermore, a receiving cavity is provided on the side of the scraper component away from the water storage tank, and a water collection trough is slidably installed in the receiving cavity. An output port is provided on the front side of the end of the water collection trough near the water storage tank, and the bottom of the water collection trough is inclined. An inclined groove is provided on the side of the scraper component located in the water collection cavity, and the long side of the inclined groove is set along the x-axis. One end of the inclined groove is connected to the output port. The end of the water collection trough away from the water storage tank is fixedly connected to the adjacent inner arm section through a connecting rod. Thus, when the telescopic arm is extended, the inner arm section pulls the water collection trough to move along the x-axis to adapt to different sizes of outer enclosures.

[0025] Furthermore, a blower is provided on one side of the protective tube, and the output end of the blower is connected to the inside of the protective tube; thus, the blower provides airflow, which is blown onto the facade of the outer enclosure structure through the placement slot, and in conjunction with the spray to simulate a wind and rain mode, the diversity of data is improved, thereby improving the accuracy of the detection.

[0026] Furthermore, the testing steps for the aforementioned automatic water spray detection device for the external envelope structure are as follows:

[0027] S1, infrared camera, visible light camera, infrared imaging detector, water pump, blower, winding machine, drive motor and related sensors are remotely controlled via wireless communication technology.

[0028] S2. The sling mechanism is activated, and the outer frame is pulled upward by the steel wire rope. The laser rangefinder measures the outer perimeter, and the outer frame extends and retracts according to the measurement data of the laser rangefinder to adapt to the size of the outer perimeter. The water pump and blower are started at the same time, and the water spray test is carried out while the outer frame moves from bottom to top in conjunction with the sling.

[0029] S3. The winding machine rewinds and unwinds the cable, causing the mounting frame to move along a preset path within the cavity. Infrared and visible light cameras capture images and transmit them to the processing unit, which marks abnormal areas according to the algorithm. Localized enhanced spraying is then activated for the abnormal points.

[0030] S4. After the spraying is completed, the sling mechanism controls the outer frame to move down, the mounting frame moves in the cavity, and the infrared imaging detector detects the facade to obtain the surface temperature distribution of each unit sprayed area. This allows for the creation of an overall humidity distribution map that can intuitively show the humidity of the inspected area, providing a reference for subsequent indoor inspections and saving personnel time in indoor leak detection.

[0031] The beneficial effects of this utility model are that the automatic water spray detection device for the external envelope structure is equipped with an infrared camera and a visible light camera. The visible light camera and the infrared camera capture the facade image of the external envelope structure, and the image processing algorithm automatically identifies cracks, corner defects, etc. Based on the data obtained from the infrared camera and the visible light camera, targeted detection can be carried out, thereby improving the accuracy of the detection.

[0032] The automatic water spray detection device for the external enclosure structure of this utility model is equipped with an outer frame and a protective pipe. The outer frame is controlled to move up and down on the outside of the facade of the external enclosure structure through a sling mechanism, thereby driving the protective pipe to move up and down on the outside of the facade of the external enclosure structure. This replaces the manual pipe laying method and improves the safety and efficiency of the detection.

[0033] The automatic water spray detection device for the outer enclosure structure of this utility model is equipped with a mounting frame, a winding machine, and a pulley. The winding machine winds up and unwinds the cable, and the mounting frame can be moved to any position in the cavity by pulling the cable, which facilitates data collection by the detection instrument.

[0034] The automatic water spray detection device for the external enclosure structure of this utility model is equipped with a water collection tray. The water pump delivers water from the water storage tank to the spray head for spraying. After passing through the facade, the water flows back to the water collection tray, and after being filtered by the filter, it enters the water storage tank, thereby realizing the reuse of water resources.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0046] Example 1: Refer to Figure 1 , Figure 8 An automatic water spray detection device for an external enclosure structure includes an external enclosure structure and an outer frame 1. The outer frame 1 is vertically arranged on the outside of the facade of the external enclosure structure. Let the side of the outer frame 1 extending in the vertical direction be the z-axis, the longer side of the outer frame 1 in the horizontal plane be the x-axis, and the side of the outer frame 1 in the horizontal plane that is perpendicular to the x-axis be the y-axis.

[0047] Wherein: the side length of the outer frame 1 extending along the z-axis is greater than the side length of the outer frame 1 extending along the x-axis, the side length of the outer frame 1 extending along the x-axis is greater than the side length of the outer frame 1 extending along the y-axis, the side of the outer frame 1 closest to the outer enclosure structure and located in the xz plane is the front side, and the front side of the outer frame 1 is parallel to the facade of the outer enclosure structure; a sling mechanism is installed on the top floor of the outer enclosure structure, and a lug for mounting the sling is installed on the top rear side of the outer frame 1; thus, vertical lifting and lowering movement is achieved through the sling mechanism, avoiding the risks of manual pipe laying and improving the safety and efficiency of inspection.

[0048] A protective tube 3 is fixedly installed on the front side of the outer frame 1. Both the outer frame 1 and the protective tube 3 are U-shaped, and both the outer frame 1 and the protective tube 3 can extend or retract along the x-axis or z-axis. Several spray heads 56 are installed along the x-axis on the side of the protective tube 3 away from the outer frame 1. The distance between the spray heads 56 can be adjusted according to the extension length of the protective tube 3 along the x-axis. A cavity is opened on the front side of the outer frame 1 that runs through the outer frame 1 along the y-axis. A mounting frame 41 is movably installed on the inner side of the outer frame 1. The mounting frame 41 can move arbitrarily within the cavity. The maximum end face of the mounting frame 41 is parallel to the facade of the outer enclosure structure.

[0049] The maximum end face of the mounting frame 41 is fixedly equipped with detection instruments, including an infrared camera and a visible light camera. The infrared camera and the visible light camera work together to capture the facade image of the external envelope structure.

[0050] Therefore, the mounting frame 41 moves within the cavity, facilitating the scanning of the external envelope by the detection components. Images acquired by the infrared and visible light cameras are transmitted to the processing unit, which uses image processing algorithms to automatically identify cracks, corner defects, etc. Based on the obtained data, targeted spray testing can be performed on cracks and corner defects, thereby improving the accuracy of the water spray test data. The detection instrument also includes an infrared imaging detector, used to detect the temperature distribution on the facade of the external envelope. The infrared imaging detector scans the facade of the external envelope, depicting its humidity distribution map, and selects the area with the highest humidity for indoor inspection to check for leaks, reducing the time required for personnel to inspect each floor.

[0051] Reference Figure 1 , Figure 8 A water collection tank 51 is provided on the lower front side of the outer frame 1. The rear side of the water collection tank 51 is fixedly connected to the outer frame 1. A water collection cavity 511 is provided on the top of the water collection tank 51. A scraper 512 is fixedly installed on the front side of the water collection tank 51. One end of the scraper 512 contacts the vertical surface of the outer enclosure. Thus, the water collection tank 51 can collect the water after spraying into the water collection cavity 511, avoiding the waste of water resources.

[0052] A water storage tank 52 is fixedly installed on one side of the water collection tank 51. The input end of the water storage tank 52 is connected to the pipeline of the water collection tank 51. A filter is installed inside the water storage tank 52. A water pump 53 is installed at the output end of the water storage tank 52. A water distributor 55 is fixedly installed inside the protective pipe 3. The output end of the water pump 53 extends into the protective pipe 3 and is connected to the pipeline of the water distributor 55. A flow sensor 541 is installed on the pipeline. The output end of the water distributor 55 is connected to the corresponding pipeline of the sprinkler head 56. A water pressure sensor 542 is installed on the pipeline. Thus, the water pump 53 delivers the water in the water storage tank 52 to the sprinkler head 56 for spraying. After passing through the vertical surface, the water flows back to the water collection chamber 511. After being filtered by the filter, the water enters the water storage tank 52, thereby realizing the reuse of water resources.

[0053] The testing steps for the aforementioned automatic water spray detection device for the external envelope structure are as follows:

[0054] S1, infrared camera, visible light camera, infrared imaging detector, water pump 53, blower, winding machine 161, drive motor and related sensors are remotely controlled via wireless communication technology.

[0055] S2. The sling mechanism is activated, and the outer frame 1 is pulled upward by the steel wire rope. The laser rangefinder 24 measures the outer perimeter. The outer frame 1 extends and retracts according to the measurement data of the laser rangefinder 24 to adapt to the size of the outer perimeter. The water pump 53 and the blower are activated at the same time, and the outer frame 1 is moved from bottom to top with the sling to carry out spray testing.

[0056] S3, the winding machine 161 works to wind and unwind the cable, so that the mounting frame 41 moves along a preset path in the cavity. The infrared camera and the visible light camera capture images and transmit them to the processing unit. Abnormal areas are marked according to the algorithm. Local enhanced spraying is started for abnormal points.

[0057] S4. After the spraying is completed, the sling mechanism controls the outer frame 1 to move down, the mounting frame 41 moves in the cavity, and the infrared imaging detector detects the facade to obtain the surface temperature distribution of each unit sprayed area. This allows for the creation of an overall humidity distribution map that can intuitively show the humidity of the inspected area, providing a reference for subsequent indoor inspections and saving personnel time in indoor leak detection.

[0058] Example 2: Refer to Figure 1 , Figure 4 , Figure 5 Based on Example 1, the following is added:

[0059] The outer frame 1 includes at least three telescopic arms, one of which has its long side vertically aligned along the z-axis, and the other two telescopic arms have their long sides horizontally aligned along the x-axis. One horizontally aligned telescopic arm is fixedly installed at one end of the vertically aligned telescopic arm, and the other horizontally aligned telescopic arm is fixedly installed at the other end of the vertically aligned telescopic arm. This forms a U-shaped outer frame 1 (see reference). Figure 1 After the dimensions of the outer enclosure are measured by the laser rangefinder 24, the telescopic arm extends or retracts as needed, thereby changing the area of ​​the front side of the outer frame 1 to adapt to different outer enclosure structures.

[0060] Where: Reference Figure 4The telescopic boom includes an outer arm 11 and an inner arm 12 sleeved inside the outer arm 11. At least one intermediate arm 13 is sleeved between the outer arm 11 and the inner arm 12. A gear 14 is fixedly installed at the bottom of the outer arm 11 and the intermediate arm 13. A rotary motor is provided on one side of the gear 14. A rack 15 is fixedly installed at the bottom of the intermediate arm 13 and the inner arm 12. The rack 15 is arranged in a stepped manner in the y-axis direction. The rack 15 and the gear 14 mesh in a one-to-one correspondence. Thus, the rotary motor controls the rack 15 to rotate, pushing the intermediate arm 13 and the inner arm 12 to move synchronously, thereby realizing the extension of the telescopic boom.

[0061] Reference Figure 1 The protective pipe 3 includes at least three telescopic sleeves. One telescopic sleeve is vertically arranged along the z-axis and is fixedly installed to the outer frame 1 via a fixed flange. The other two telescopic sleeves are horizontally arranged along the x-axis. One of the horizontally arranged telescopic sleeves is set at one end of the vertically arranged telescopic sleeve via a corner tube, and the other horizontally arranged telescopic sleeve is set at the other end of the vertically arranged telescopic sleeve via a corner tube. Thus, when the outer frame 1 is expanded, the corresponding protective pipe 3 extends accordingly, so that the water spray detection can be adapted to different external protective structures.

[0062] Reference Figure 5 The telescopic sleeve includes an outer sleeve 31, an inner hollow tube 32, and at least one intermediate tube 33 sleeved between the outer sleeve 31 and the inner hollow tube 32. The outer sleeve 31, the inner hollow tube 32, and the intermediate tube 33 move synchronously through a synchronous pulley and rope mechanism. Specifically, a pulley 2 34 is provided at one end of the inner wall of the outer sleeve 31 and the intermediate tube 33, a pulley 331 is provided at the other end of the inner wall of the intermediate tube 33, and a gathering wheel 311 is provided at the other end of the inner wall of the outer sleeve 31. The inner side of the gathering wheel 311 is provided with... A torsion spring; the cable end of the retractor 311 passes through pulley 34 and pulley 331 at the outer sleeve 31 and the middle tube 33 respectively, and is then fixed to the inner wall of the outer sleeve 31; one end of the inner hollow tube 32 located inside the middle tube 33 is fixedly connected to the cable; the outer sleeve 31, which is arranged laterally, is fixedly connected to the adjacent outer arm 11, and the inner hollow tube 32, which is arranged laterally, is fixedly connected to the adjacent inner arm; thus, when the telescopic arm extends, it pulls the inner hollow tube 32 to move, thereby driving the middle tube 33 to move synchronously.

[0063] Reference Figure 1 The front sides of the outer sleeve 31, inner hollow tube 32, and intermediate tube 33 are fixedly connected to the spray heads 56 one by one. The front sides of the inner hollow tube 32 and intermediate tube 33 are provided with placement grooves, the long side of which is set along the x-axis, and one end of the placement groove passes through one end of the corresponding inner hollow tube 32 or intermediate tube 33. The placement groove and the spray head 56 are located on the same straight line. Thus, when the telescopic sleeve extends or retracts, the spacing between the spray heads 56 is dynamically adjusted according to the extension stroke. The placement grooves ensure that the spray heads 56 do not interfere with the movement of the telescopic sleeve.

[0064] Example 3: Based on Example 2, the following is added:

[0065] Reference Figure 2 Support plates 16 are fixedly installed on the inner sides of the horizontally arranged outer arm 11 and inner arm 12, respectively. A winding machine 161 is fixedly installed on the rear side of the support plate 16, and a pulley 42 is fixedly installed on the rear side of the mounting frame 41. The winding machine 161 and the pulley 42 correspond one-to-one and are connected by a cable. One end of the cable is fixedly connected to the support plate 16. Thus, multiple winding machines 161 control the cable length and, in combination with the pulley 42, enable the mounting frame 41 to move freely within the cavity.

[0066] Example 4: Figure 1 , Figure 3 As shown, the following is added based on Example 3:

[0067] Reference Figure 1 The top of the outer frame 1 is provided with a ranging mechanism 2, which includes a moving component and a laser rangefinder 24. The laser rangefinder 24 is fixedly mounted on the moving component, which is used to control the laser rangefinder 24 to move back and forth in the x-axis direction. Thus, the laser rangefinder 24 can obtain the outer enclosure size data in real time, which makes it easier for the winding machine 161 to control the movement range of the mounting frame 41 and avoid the detection instrument from obtaining useless data. At the same time, it ensures that the outer frame 1 can be adapted to facades of different sizes after adjustment.

[0068] Where: Reference Figure 3 The moving component includes a primary slide rail 21, a secondary slide rail 22, and a sliding frame 23. The bottom of the primary slide rail 21 is fixedly connected to the top of the outer frame 1. There are two secondary slide rails 22, which are arranged opposite each other and do not contact each other. The two secondary slide rails 22 are arranged back and forth along the y-axis. The side of the secondary slide rail 22 is slidably connected to the inner wall of the primary slide rail 21. The sliding frame 23 corresponds to the secondary slide rail 22 one by one, and the bottom of the sliding frame 23 is slidably connected to the side wall of the secondary slide rail 22. The laser rangefinder 24 corresponds to the sliding frame 23 one by one, and the base of the laser rangefinder 24 is fixedly installed on the top of the corresponding sliding frame 23. The inner wall of the sliding frame 23 and the top of the secondary slide rail form a cavity. The top of the secondary slide rail is provided with a rack 221.

[0069] Example 5: Based on Example 4, the following is added:

[0070] Reference Figure 1 , Figure 3 To accommodate the extension and retraction of the outer frame 1: the top of the horizontally arranged outer arm 11 is fixedly connected to the first-level slide rail 21, and the top of the middle arm 13 and the inner arm 12 are provided with pulleys 42 that slide with the first-level slide rail 21; a connecting plate 121 is provided at the end of the inner arm away from the outer arm 11, and one end of the connecting plate 121 is fixedly connected to the second-level slide rail 22 located on the front side; thus, the moving inner arm 12 pulls the corresponding second-level slide rail 22 to move along the x-axis, thereby extending the displacement distance of the laser rangefinder 24.

[0071] Example 6: Based on Example 2, the following is added:

[0072] Reference Figure 6 , Figure 7 The scraper component 512 has a receiving cavity 5121 on the side away from the water storage tank 52. A water collection trough 513 is slidably installed in the receiving cavity 5121. An outlet is opened on the front side of the end of the water collection trough 513 near the water storage tank 52. The bottom of the water collection trough 513 is inclined. An inclined groove 5122 is opened on the side of the scraper component 512 located in the water collection cavity 511. The long side of the inclined groove 5122 is set along the x-axis. One end of the inclined groove 5122 is connected to the outlet. The end of the water collection trough 513 away from the water storage tank 52 is fixedly connected to the adjacent inner arm section through a connecting rod. Thus, when the telescopic arm is extended, the inner arm section 12 pulls the water collection trough 513 to move along the x-axis to adapt to the outer protection of different sizes.

[0073] In addition, a blower is installed on one side of the protective tube 3, and the output end of the blower is connected to the inside of the protective tube 3; thus, the blower provides air power and blows it onto the facade of the outer enclosure structure through the placement slot, which, together with the spray simulation of wind and rain mode, enhances the diversity of data and thus improves the accuracy of detection.
