[0004] However, after the images of the building facade are acquired, they need to be identified and analyzed in the later stages. When using drones to acquire images, it is not possible to quickly and accurately locate the damaged areas after identifying them. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a building facade damage detection device that utilizes thermal imaging and visible light images.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A building facade damage detection device utilizing thermal imaging and visible light images includes a camera detection module, an information storage module, and a bidirectional movement mechanism. The bidirectional movement mechanism includes two translation components respectively disposed on the upper and lower sides of the building facade and operating synchronously, with a vertical movement component disposed between the two translation components. The camera detection module and the information storage module are both disposed on the vertical movement component, and the image signal acquisition direction of the camera detection module is facing the building facade.

[0008] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the translation component includes two detachably fixed connecting plates on both sides of the building facade. The outer ends of the connecting plates extend horizontally away from the building facade. A first transverse rope and a second transverse rope are fixed between the two connecting plates. The first transverse rope is located outside the second transverse rope. A first self-propelled component is installed on the first transverse rope, and a first horizontal holding slider connected to the first self-propelled component is slidably connected to the second transverse rope.

[0009] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the vertical moving component includes a first vertical rope and a second vertical rope fixed between two first self-propelled components. The second self-propelled component is mounted on the first vertical rope, and a second horizontal holding slider connected to the second self-propelled component is slidably connected to the second vertical rope. The camera detection module and the information storage module are both mounted on the second self-propelled component.

[0010] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the camera detection module includes a visible light camera, an infrared thermal imaging camera, and a camera mounting base, wherein the visible light camera and the infrared thermal imaging camera are mounted on the side of the camera mounting base facing the building facade.

[0011] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the information storage module includes an information storage component, which is disposed within the camera mounting base.

[0012] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the first self-propelled component includes a first outer shell slidably mounted on a first transverse rope. A first traveling wheel is disposed within the first outer shell and abuts against the first transverse rope. A first motor is disposed on the outside of the first outer shell, and the first motor is poweredly connected to the first traveling wheel via a first reducer.

[0013] In the aforementioned building facade damage detection device utilizing thermal imaging and visible light images, the second self-propelled component includes a second outer shell slidably mounted on a first vertical rope. A second traveling wheel is disposed within the second outer shell and abuts against the first vertical rope. A second motor is disposed on the outside of the second outer shell, and the second motor is poweredly connected to the second traveling wheel via a second reducer.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] 1. The camera detection module can acquire image signals from the building facade and store the images in the information storage module. The translation component can move the vertical movement component and the camera detection module horizontally, and the vertical movement component can move the camera detection module vertically. When the camera detection module acquires images of the building facade as a whole, it divides the facade into several vertically distributed horizontal detection zones according to the image acquisition area of ​​the camera detection module. Then, it sequentially completes the detection of several horizontal detection zones from top to bottom. When acquiring images of one horizontal detection zone, the translation component moves the camera detection module horizontally to acquire images. After acquiring images of one horizontal detection zone, the vertical movement component moves the camera detection module down to the next horizontal detection zone. When locating damaged parts of the building facade later, the camera detection module's movement speed and the shooting time of the damaged points can quickly and accurately determine the location of the damaged points on the building facade.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0024] like Figures 1-3 As shown, a building facade damage detection device utilizing thermal imaging and visible light images includes a camera detection module, an information storage module, and a bidirectional moving mechanism 1. The bidirectional moving mechanism 1 includes two translation components 3 respectively disposed on the upper and lower sides of the building facade 2 and operating synchronously. A vertical moving component 4 is disposed between the two translation components 3. The camera detection module and the information storage module are both disposed on the vertical moving component 4, and the image signal acquisition direction of the camera detection module is towards the building facade 2.

[0025] In this invention, the camera detection module can acquire image signals from the building facade and store the images in the information storage module. The translation component 3 can drive the vertical movement component 4 and the camera detection module to move horizontally. The vertical movement component 4 can drive the camera detection module to move vertically. When the camera detection module acquires the overall image of the building facade, it divides the building facade into several vertically distributed horizontal detection intervals according to the image acquisition area of ​​the camera detection module. Then, it sequentially completes the detection of several horizontal detection intervals from top to bottom. When the image acquisition of one horizontal detection interval is completed, the translation component 3 drives the camera detection module to move horizontally for acquisition. After the image acquisition of one horizontal detection interval is completed, the vertical movement component drives the camera detection module to move down to the next horizontal detection interval. When locating the damaged parts of the building facade later, the position of the damaged point on the building facade can be quickly and accurately determined by the moving speed of the camera detection module and the shooting time of the damaged point.

[0026] Specifically, the translation component 3 includes two detachable connecting plates 5 fixed to both sides of the building facade 2. The outer ends of the connecting plates 5 extend horizontally away from the building facade 2. A first horizontal rope 6 and a second horizontal rope 7 are fixed between the two connecting plates 5. The first horizontal rope 6 is located outside the second horizontal rope 7. A first self-propelled component 8 is installed on the first horizontal rope 6. A first horizontal holding slider 9, connected to the first self-propelled component 8, is slidably connected to the second horizontal rope 7. The first self-propelled component 8 can move horizontally along the first horizontal rope. The synchronized movement of the first self-propelled components 8 on the two translation components 3 can drive the vertical movement component 4 and the camera detection module to move horizontally, thereby enabling the camera detection module to complete image acquisition of the horizontal detection area. The first horizontal holding slider 9 can keep the first self-propelled component 8 in a horizontal state.

[0027] Specifically, the vertical moving component 4 includes a first vertical rope 10 and a second vertical rope 11 fixed between two first self-propelled components 8. A second self-propelled component 12 is mounted on the first vertical rope 10. A second horizontal holding slider 13, connected to the second self-propelled component 12, is slidably connected to the second vertical rope 11. Both the camera detection module and the information storage module are mounted on the second self-propelled component 12. The second self-propelled component can move vertically along the first vertical rope, thereby moving the camera detection module to the next horizontal detection zone. The first horizontal holding slider 9 keeps the second self-propelled component in a horizontal position, preventing the image acquisition direction of the image detection module from shifting.

[0028] Specifically, the camera detection module includes a visible light camera 14, an infrared thermal imaging camera 15, and a camera mounting base 16. The visible light camera 14 and the infrared thermal imaging camera 15 are mounted on the side of the camera mounting base 16 facing the building facade 2. The information storage module includes an information storage component, which is disposed within the camera mounting base 16. Using the visible light camera 14 and the infrared thermal imaging camera 15, visible light images and infrared thermal images can be acquired, thereby improving detection accuracy.

[0029] Specifically, the first self-propelled component 8 includes a first outer shell 17 slidably mounted on a first transverse rope 6. Inside the first outer shell 17 is a first traveling wheel 18 that abuts against the first transverse rope 6. A first motor 19 is mounted on the outside of the first outer shell 17, and the first motor 19 is poweredly connected to the first traveling wheel 18 via a first reducer 20. The first motor 19 drives the first traveling wheel 18 to rotate via the first reducer 20. The rotation of the first traveling wheel 18 utilizes the friction between the first traveling wheel 18 and the first transverse rope to propel the first outer shell 17 horizontally along the first transverse rope.

[0030] Specifically, the second self-propelled component 12 includes a second outer shell 21 slidably mounted on the first vertical rope 10. Inside the second outer shell 21 is a second traveling wheel 22 that abuts against the first vertical rope 10. A second motor 23 is mounted on the outside of the second outer shell 21, and the second motor 23 is poweredly connected to the second traveling wheel 22 via a second reducer 24. The second motor drives the second traveling wheel to rotate via the second reducer. The rotation of the second traveling wheel utilizes the friction between the second traveling wheel and the first vertical rope to propel the second outer shell vertically along the first vertical rope.

[0031] Specifically, motor 19 and motor 23 are servo motors.

[0032] Preferably, the circumferential surfaces of the first traveling wheel 18 and the second traveling wheel 22 are recessed with arc-shaped grooves 25. The arc-shaped grooves 25 can increase the friction between the wheels and the rope to ensure the movement effect.

[0033] Specifically, the first horizontal holding slider 9 is fixed to the first outer shell 17 through the first fixing plate to maintain the position of the first outer shell, and the second horizontal holding slider 13 is fixed to the second outer shell 21 through the second fixing plate to maintain the position of the second outer shell.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this article frequently uses terms such as bidirectional moving mechanism 1, building facade 2, translation component 3, vertical moving component 4, connecting plate 5, first horizontal rope 6, second horizontal rope 7, first self-propelled component 8, first horizontal holding slider 9, first vertical rope 10, second vertical rope 11, second self-propelled component 12, second horizontal holding slider 13, visible light camera 14, infrared thermal imaging camera 15, camera mounting base 16, first outer shell 17, first traveling wheel 18, first motor 19, first reducer 20, second outer shell 21, second traveling wheel 22, second motor 23, second reducer 24, arc groove 25, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
