Description

Technical Field

[0001] This invention relates to an infrared detection device, specifically an infrared detection device that can be suspended from a height to scan for hollow areas in exterior walls, belonging to the field of building exterior wall inspection technology. Background Technology

[0002] As a key part of the building envelope, the exterior wall of a building has functions of protection, decoration and energy saving. During long-term service, it is prone to hollowing problems, that is, the surface material peels off locally due to adhesive failure. This not only affects the appearance, but also reduces the thermal insulation performance and poses a safety hazard of falling off. Modern infrared detection equipment for exterior wall hollowing uses the principle of infrared thermal imaging to capture areas of abnormal temperature on the wall surface, so as to achieve large-area, non-contact, fast and accurate hazard location. This technology greatly improves detection efficiency and coverage, and provides technological support for preventive maintenance and building safety.

[0003] A search revealed a novel building exterior wall hollow detection device disclosed in Chinese Patent Publication No. CN220764724U, comprising a drone and a building exterior wall hollow detector. The drone has an adjustment box attached to its bottom, and the bottom of the adjustment box is rotatably sleeved with the top of the building exterior wall hollow detector. A transmission frame is hinged to the top of the adjustment box, and a sliding sleeve is slidably connected to the surface of the transmission frame. A hinge rod is hinged to the bottom of the transmission frame, and a rack is hinged to the left end of the hinge rod. The teeth of the rack mesh with a gear shaft.

[0004] While the above-mentioned solutions can scan and detect exterior walls, they have significant drawbacks in practical applications. Because the current devices are hoisted by drones, the drones can only keep the detection equipment horizontal during flight. When scanning and detecting exterior walls of slopes with different inclinations or irregularly shaped buildings, this will affect the accuracy of thermal imaging and lead to missed detections. To address these issues, we provide an infrared detection device that can be hoisted from a height to scan for hollow areas in exterior walls. Summary of the Invention

[0020] This invention provides an infrared detection device that can be hoisted from a height to scan for hollow areas in exterior walls.

[0021] Please see Figure 1 The system includes a hoisting drone body 1. The hoisting drone body 1 and the hoisting box 201 are installed using a high-strength, corrosion-resistant L-shaped fixing plate and bolts. This ensures that the hoisting box 201 is securely hoisted below the hoisting drone body 1 and facilitates disassembly and maintenance by the user in the future. The hoisting drone body 1 is stabilized by a flight control system. Core components include a gyroscope and accelerometer to sense changes in the aircraft's attitude in real time, and a GPS / RTK module for precise positioning. Based on this sensor data, the flight control processor performs high-speed calculations using a self-stabilizing algorithm and then dynamically adjusts the speed of each propeller motor to actively counteract external interference, thereby achieving precise hovering and stable flight. The above describes the existing mature technology of the hoisting drone body 1, which will not be described in detail in this application.

[0022] Please refer to it again. Figure 1 , Figure 2 , Figure 6 and Figure 7The hoisting drone body 1 is internally equipped with an adjustment mechanism 2. The adjustment mechanism 2 includes a hoisting box 201, a driven mounting plate 202, and a mounting box 203. The outer surface of the hoisting box 201 is fixedly connected to the hoisting drone body 1, the outer surface of the driven mounting plate 202 is slidably connected to the hoisting box 201, and the top surface of the mounting box 203 is fixedly connected to the driven mounting plate 202. The mounting box 203 effectively provides fixed protection for the components in the adjustment mechanism 2, effectively preventing external dust and impurities from adhering to the components after the adjustment mechanism 2 extends out of the hoisting box 201, thus preventing the components from malfunctioning. This effectively improves the overall service life of the device and reduces the maintenance rate.

[0023] A driven shaft 204 is rotatably connected to the bottom surface of the driven mounting plate 202. A support frame 205 is rotatably connected to the outer surface of the driven shaft 204. A first driven worm gear 206 is fixedly connected to the outer surface of the driven shaft 204. A second driven worm gear 207 and a driven rotating tube 208 are rotatably connected to the outer surface of the driven shaft 204. One end of the driven rotating tube 208 is fixedly connected to the second driven worm gear 207. The end of the driven rotating tube 208 away from the second driven worm gear 207 is fixedly connected to the support frame 205. The outer surface of the driven rotating tube 208 is rotatably connected to the mounting box 203. Through the arrangement of the driven mounting plate 202, the driven shaft 204 is effectively supported and limited. The function of the bearing is to drive the first driven worm gear 206 to synchronously drive the driven shaft 204 to rotate. Bearings are installed between the driven shaft 204 and the support frame 205, the second driven worm gear 207 and the driven rotating tube 208. The inner ring of the bearing is fixedly connected to the driven shaft 204, and the outer ring of the bearing is fixedly connected to the support frame 205, the second driven worm gear 207 and the driven rotating tube 208. The bearing effectively limits the movement of the support frame 205, the second driven worm gear 207 and the driven rotating tube 208, so that the support frame 205, the second driven worm gear 207 and the driven rotating tube 208 can only rotate stably around the driven shaft 204 as the axis, and cannot move up and down.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A first driven bevel gear 209 is fixedly connected to one end of the driven shaft 204 away from the driven mounting plate 202. A second driven bevel gear 210 is meshed with the outer surface of the first driven bevel gear 209. A bearing driven adjusting rod 211 is fixedly connected to the inner wall of the second driven bevel gear 210. The outer surface of the bearing driven adjusting rod 211 is rotatably connected to the bearing frame 205. By driving the driven shaft 204 to rotate, the second driven bevel gear 210 on the surface of the first driven bevel gear 209 can be driven to rotate synchronously, effectively changing the power direction of the driven shaft 204. The bearing driven adjusting rod 211 effectively limits the second driven bevel gear 210, making the surface of the second driven bevel gear 210 mesh more firmly with the first driven bevel gear 209.

[0025] An adjustment frame 212 is fixedly connected to the outer surface of the driven adjustment rod 211. An infrared detection device body 213 is fixedly connected to the inner wall of the adjustment frame 212. The infrared detection device body 213 is installed on the adjustment frame 212 by bolts. The bolt fixing facilitates the disassembly and maintenance of the infrared detection device body 213 by the staff. The infrared detection device body 213 detects the infrared radiation energy on the surface of the building's exterior wall and converts it into a temperature distribution map. Then, it actively or passively records the temperature change of the wall surface. Due to thermal anomalies such as material defects, hollow areas, leaks, or insulation layer problems, the surface temperature distribution may be uneven, forming obvious temperature difference areas in the thermal image, thereby locating potential problem points.

[0026] The inner wall of the mounting box 203 is rotatably connected to two driving worm gears 214. The outer surfaces of the two driving worm gears 214 mesh with the first driven worm wheel 206 and the second driven worm wheel 207, respectively. The mounting box 203 effectively supports and limits the two driving worm gears 214, thus making the device more stable during the driving process.

[0027] A signal transceiver module 215 and a synchronization control module 216 are fixedly connected to the inner wall of the mounting box 203. A first connecting wire 217 is electrically connected between the signal transceiver module 215 and the synchronization control module 216. A motor protective shell 218 is fixedly connected to the inner wall of the mounting box 203. Two drive motors are fixedly connected to the inner wall of the motor protective shell 218. The output ends of the two drive motors are fixedly connected to two active worm gears 214 respectively. A second connecting wire 219 is electrically connected between the synchronization control module 216 and the motor protective shell 218. A heat dissipation slot is provided on the outer surface of the mounting box 203. The heat dissipation slot can effectively dissipate heat from the electrical equipment inside the mounting box 203, ensuring that the electrical equipment can operate safely for a long time.

[0028] The signal transceiver module 215 is responsible for receiving remote control commands from the terminal. When the signal transceiver module 215 receives a valid command, it will trigger the synchronous control module 216 to work through the first connecting wire 217. The synchronous control module 216 generates corresponding motor control signals according to the received command content. The synchronous control module 216 is connected to the two drive motors inside the motor protective shell 218 through the second connecting wire 219. The synchronous control module 216 can drive them to achieve precise synchronous rotation, or drive only one of the motors to run independently as needed.

[0029] Please refer to it again. Figure 2 , Figure 3 , Figure 8 and Figure 9 The hoisting drone body 1 is equipped with an opening and closing mechanism 3. The opening and closing mechanism 3 includes a driven connecting shaft 301. The outer surface of the driven connecting shaft 301 is rotatably connected to the hoisting box 201. A sealing ring is installed between the driven connecting shaft 301 and the hoisting box 201. The sealing ring can effectively prevent external dust and impurities from entering and affecting the rotational stability of the driven connecting shaft 301.

[0030] One end of the driven connecting shaft 301 is fixedly connected to a driven meshing wheel 302. A sliding gear 303 is meshed with the outer surface of the driven meshing wheel 302. The outer surface of the sliding gear 303 is slidably connected to the lifting box 201. The bottom surface of the sliding gear 303 is fixedly connected to the driven mounting plate 202. By driving the driven connecting shaft 301 to rotate, the driven meshing wheel 302 can be effectively driven to rotate simultaneously. The rotation of the driven meshing wheel 302, through the meshing force, can effectively drive the driven mounting plate 202 on the bottom surface of the sliding gear 303 to slide vertically in the inner wall of the lifting box 201.

[0031] A driving engagement wheel 304 is fixedly connected to one end of the driven connecting shaft 301 away from the driven meshing wheel 302. Two sliding racks 305 are meshed on the outer surface of the driving engagement wheel 304. A connecting slide rod 306 is fixedly connected to one end of each sliding rack 305. The outer surfaces of each sliding rack 305 and the connecting slide rod 306 are slidably connected to the lifting box 201. By driving the driving engagement wheel 304 to rotate, the two sliding racks 305 can be driven to slide closer or further away from each other on the surface of the lifting box 201 simultaneously according to the meshing force. A through groove is provided on the outer surface of the connecting slide rod 306 at one end of the sliding rack 305 above the driving engagement wheel 304, so that when the two sliding racks 305 are driven to move closer to each other, the sliding rack 305 below the driving engagement wheel 304 can pass smoothly, effectively avoiding jamming.

[0032] Each connecting slide bar 306 has a sealing door plate 307 fixedly connected to the end away from the sliding rack 305. Each sealing door plate 307 has a limiting slide bar 308 fixedly connected to its top surface. The bottom surface of the hoisting box 201 has a limiting slide groove 309 that matches the limiting slide bar 308. Through the synergistic effect of the limiting slide bar 308 and the limiting slide groove 309, the sealing door plate 307 is effectively supported and limited, making the two sealing door plates 307 more stable during opening and closing.

[0033] A protective shell 310 is fixedly connected to the outer surface of the hoisting box 201. The inner wall of the protective shell 310 is slidably connected to the connecting slide rod 306. A rotating motor 311 is fixedly connected to the inner wall of the protective shell 310. The output end of the rotating motor 311 is fixedly connected to the active meshing wheel 304. By starting the rotating motor 311, the active meshing wheel 304 can be effectively driven to rotate. The protective shell 310 not only supports and fixes the rotating motor 311, but also protects the components in the opening and closing mechanism 3, preventing external dust and impurities from entering and affecting the normal operation of the components.

[0034] The inner wall of the hoisting box 201 is slidably connected to a limiting slide rod 312. One end of the limiting slide rod 312 is fixedly connected to a support rod 313. The end of the support rod 313 away from the limiting slide rod 312 is fixedly connected to a paint spraying assembly 314. The bottom surface of the paint spraying assembly 314 is fixedly connected to a driven rod 315. The end of the driven rod 315 away from the paint spraying assembly 314 is rotatably connected to two swing arms 316. The ends of the two swing arms 316 away from the driven rod 315 are hinged to the sealing door panel 307. During the process of driving the two sealing door panels 307 to move away from each other, the combined action of the driven rod 315 and the swing arms 316 can drive the paint spraying assembly 314 to extend towards the wall surface. By opening the paint spraying assembly 314, some minor exterior wall problems that are not easily found by the naked eye can be effectively marked with paint, thus facilitating subsequent exterior wall construction and maintenance by staff.

[0035] The signal transceiver module 215, synchronization control module 216, drive motor, and rotation motor 311 in this application are all mature and widely known general electrical components and electronic elements in the relevant technical field. These components are commonly used in existing technical solutions, and their basic functional principles, standard internal structures, and mainstream implementation models have been fully recognized by those skilled in the art and are regarded as common knowledge. Therefore, in order to focus on the core contribution of this application to the inventiveness, the specification will not redundantly describe the specific selection parameters, internal circuit topology, or mechanical structure details of these general equipment. It should be clarified that these components themselves are not the technical improvement points of this application solution, and their roles in the system can be flexibly replaced by equivalent power sources according to actual needs to achieve the same functional positioning.

[0036] The structural representations of the components shown in the accompanying drawings are intended to provide conceptual references. Their forms and interrelationships provide a basic framework for understanding the overall design intent. It is important to emphasize that these illustrations are not rigid templates for the final product. In the process of transforming the design into an actual product or its subsystem, in-depth and meticulous adaptive adjustments and optimizations must be made based on the specific constraints of the project. This mainly includes fully considering the core functional requirements of the specific application scenario, rigorously assessing the physical limitations of the actual assembly, and strictly referring to the current material properties, manufacturing process levels, and cost control requirements. Therefore, it is necessary to systematically review and revise the geometric parameters, key dimensions, and material specifications of the components to ensure that the parameters achieve an optimal balance between theoretical feasibility and engineering practicality.

[0037] Working principle: First, the rotating motor 311 drives the active meshing wheel 304 to rotate. The rotation of the active meshing wheel 304, through meshing force, drives the connecting slide rods 306 on one end of the two sliding racks 305 to move away from each other. During the movement of the two connecting slide rods 306 away from each other, in conjunction with the synergistic effect of the limiting slide strip 308 and the limiting slide groove 309, the two sealing door panels 307 are effectively driven to move away from each other, opening the lower opening of the hoisting box 201. During the process of driving the active meshing wheel 304 to open the lower opening of the hoisting box 201, the active meshing wheel 304 will drive the driven meshing wheel 302 at one end of the driven connecting shaft 301 to rotate synchronously. The driven meshing wheel 302 rotates... The drive mechanism, through meshing force, causes the sliding gear 303 to slide down within the lifting box 201. The sliding gear 303's downward movement simultaneously causes the driven mounting plate 202 to slide down within the lifting box 201, effectively extending the adjusting mechanism 2 from within the lifting box 201. Next, the drive worm 214, meshing with the first driven worm gear 206, drives the first driven worm gear 206 to rotate. The rotation of the first driven worm gear 206 drives the driven shaft 204 to rotate, which in turn drives the first driven bevel gear 209 to rotate. The rotation of the first driven bevel gear 209, through meshing force, drives the second driven bevel gear 210 to rotate, which in turn drives the driven adjustment mechanism 2. Rotating rod 211 causes the driven adjusting rod 211 to rotate, which in turn drives the infrared detection device body 213 on the inner wall of the adjusting frame 212 to rotate around the driven adjusting rod 211, effectively adjusting the detection angle of the infrared detection device body 213. When both driving worm gears 214 are rotated simultaneously, the meshing force drives the bearing frame 205 to rotate around the driven shaft 204. The rotation of the bearing frame 205 drives the adjusting frame 212 on the surface of the driven adjusting rod 211 to rotate, and the rotation of the adjusting frame 212 drives the infrared detection device body 213 to rotate, effectively adjusting the detection direction of the infrared detection device body 213. This allows the device to flexibly adjust the infrared direction. The detection direction and angle of the detection device body 213 enable it to remain perpendicular to slopes of varying inclination or irregular building exterior walls. This design significantly improves detection efficiency and device compatibility, effectively avoiding missed detections and low detection accuracy caused by irregular exterior wall shapes. By driving the driven engagement wheel 302 and the active engagement wheel 304 to rotate synchronously in both directions, the infrared detection device body 213 can extend during operation and be completely retracted into the hoisting box 201 when idle. It is then sealed and protected by the sealing door panel 307, effectively preventing dust, moisture erosion, and accidental collision damage, significantly improving the equipment's transport convenience and protection reliability.
