Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection, in particular to an automatic detection device for the flatness of building facades. Background Art

[0002] The flatness of a building facade refers to the smoothness and flatness of the outer wall surface of a building. High-quality building construction requires a high flatness of the facade to ensure the aesthetics, structural stability, and durability of the building. In the construction industry, it is necessary to detect the flatness of the building facade. In the prior art, manual measurement or laser level is usually used for detection. Manual measurement uses tools such as rulers and straightedges for manual measurement. This method depends on the experience and technical level of the measurer, with low efficiency and easy to produce errors. Although the laser level has high precision, it can only measure local points and cannot comprehensively cover the entire facade.

[0003] In the prior art, there is a method of detecting flatness by using a drone to control a collector. The drone flies to a designated position of the building for selection, and scans and collects the data of the building by rotating a scanner below. However, the lens of the collector on the bottom surface of the drone needs to be rotated manually by remote control, and the accuracy of manual remote control is poor, and it is impossible to accurately control the same rotation angle each time. At the same time, during the collection process, it is necessary to give the drone scanner time to scan and process the data, and there may be a phenomenon that the rotation is too fast to stop in time, resulting in poor data collection accuracy. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems of poor rotation accuracy of the manual remote control scanner for data collection by the drone and the influence of too short static time on data collection in the flatness detection of the above background art, and to propose an automatic detection device for the flatness of building facades.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] An automatic detection device for the flatness of building facades includes a drone structure, and a detection structure is arranged on the bottom surface of the drone structure. The detection structure includes:

[0007] A rotating gear ring, which is rotatably connected to the bottom of the drone structure. A scanner is fixedly connected to the bottom surface of the rotating gear ring, and a stability system is arranged in the scanner;

[0008] A driving motor, which is relatively fixed to the bottom surface of the drone structure. The output end of the driving motor is connected to a driving disk, and a number of continuous meshing teeth are arranged on the circumferential surface of the driving disk;

[0009] A transmission gear, which is rotatably connected to the bottom of the drone structure. The transmission gear is meshed with the meshing teeth on the surface of the driving disk and the rotating gear ring.

[0010] As a further solution of the present utility model: Support frames are arranged on both sides of the UAV structure, and the bottoms of the support frames on both sides are inclined outward.

[0011] As a further solution of the present utility model: The bottom surfaces of the support frames on both sides are located in the same horizontal plane.

[0012] As a further solution of the present utility model: A communication device is arranged inside the UAV structure, and the scanner is communicatively connected to the communication device.

[0013] As a further solution of the present utility model: The centers of the driving disc and the rotating gear ring coincide.

[0014] As a further solution of the present utility model: The driving disc, the driving gear and the rotating gear ring are located in the same horizontal plane.

[0015] Advantages of the present utility model:

[0016] (1) For the automatic building facade flatness detection device of the present utility model, by setting a detection structure, the output end of the driving motor of the detection structure drives the driving disc to rotate. The continuous meshing teeth arranged in the circumferential area on the surface of the driving disc can periodically drive the driving gear to rotate, and the driving gear periodically drives the rotating gear ring to rotate, thereby indirectly driving the scanner to rotate periodically, so that the scanner is stationary for collection after rotation, providing time for collection and data processing noise reduction transmission;

[0017] (2) For the automatic building facade flatness detection device of the present utility model, by setting a driving disc, a driving gear and a rotating gear ring, the driving disc drives the rotating gear ring to rotate periodically by a specified angle. Compared with manually controlling the rotation of the lens, the accuracy is higher, and the radii of the driving disc and the driving gear and the number of meshing teeth on the surface can be adjusted to indirectly adjust the rotation angle of the rotating gear ring and adjust the rotation angle of the scanner.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 As shown, the present invention is an automatic detection device for the flatness of the building facade, including a drone structure 1. A number of wings 11 are arranged on the surface of the drone structure 1. Support frames 12 are arranged on both sides of the drone structure 1. The two support frames 12 extend downward to the lower part of the drone structure 1. The bottom surfaces of the two support frames 12 are located in the same horizontal plane. A detection structure 2 is arranged on the bottom surface of the drone structure 1. The rotating gear ring 21 of the detection structure 2 is rotatably connected to the bottom surface of the drone structure 1. A spherical connecting housing 23 is fixedly arranged on the bottom surface of the transmission gear ring. A scanner 24 is arranged on the outer surface of the connecting housing 23. A communication device is arranged inside the drone structure 1. The communication device is communicatively connected to the scanner 24 and an external terminal; a stability maintenance system is arranged inside the scanner 24, so that the scanner 24 can maintain stable scanning and prevent shaking during the hovering process of the drone structure 1. A driving motor 22 is arranged on the bottom surface of the connecting housing 23. The driving motor 22 is relatively fixed to the drone structure 1. The output end of the driving motor 22 is arranged vertically upward. A driving disc 25 is fixedly arranged at the output end of the driving motor 22. The driving disc 25 is arranged along the horizontal direction. The driving disc 25 is located in the horizontal plane inside the rotating gear ring. A number of continuous engaging teeth 27 are arranged on a partial circumferential area of the driving disc 25. A driving gear 26 is arranged between the driving disc 25 and the rotating gear ring 21. The driving gear 26 is rotatably connected to the bottom surface of the drone structure 1. The tooth surface of the driving gear 26 can be meshed with the engaging teeth 27 and the inner ring of the rotating gear ring 21.

[0025] When using this automatic detection device for the flatness of building facades, the drone structure 1 flies to a designated position outside the building and hovers. Subsequently, the detection structure 2 is activated through the terminal device for detection. The drive motor 22 of the detection structure 2 rotates continuously, and the output end of the drive motor 22 drives the drive disk 25 to rotate, causing the continuous engagement teeth 27 in a partial area on the surface of the drive disk 25 to periodically engage and drive with the drive gear 26. When the engagement teeth 27 engage with the drive gear 26, it drives the drive gear 26 to rotate, and the drive gear 26 itself drives the rotating gear ring 21 on the other side to rotate. The rotating gear ring 21 drives the connecting housing 23 and the scanner 24 below to collect data. The scanner 24 scans and collects the designated area below, and transmits the collected data to the terminal device through the communication device inside the drone structure 1. The drive disk 25 indirectly drives the rotating gear ring 21 to move periodically, so that the scanner 24 will remain stationary for a period of time after rotation, so as to have time for focusing shooting and data processing, and collect clearer photos. When the scanner 24 scans the building facade to obtain high-density point cloud data, the drone structure 1 internally performs denoising processing on the collected point cloud data, removing abnormal points and noise points, so as to collect a clear point cloud map and transmit it to the terminal device for data processing. The rotating gear ring 21 drives the collector to rotate periodically, providing time for the scanner 24 to collect and process optimized data. At the same time, the drive motor 22 rotates continuously, periodically adjusting the rotating gear ring 21 to rotate along a designated angle to scan and collect the flatness of the building facade at different visible angles. The rotation of the scanner 24 at a fixed angle is more accurate than manual control. By adjusting the radius and the number of teeth on the surface of the drive disk 25 itself, or the radius and the number of teeth of the drive gear 26, the rotation angle of the connecting housing 23 and the scanner 24 can be adjusted periodically. After the collected denoised point cloud map is transmitted to the terminal, the data of the same area at different angles are aligned and registered, and after establishing a reference plane for the same area, its flatness is calculated.

[0026] Working principle of the utility model: The automatic detection device for the flatness of the building facade of the utility model is provided with a detection structure 2. The output end of the drive motor 22 of the detection structure 2 drives the drive disk 25 to rotate. The continuous meshing teeth 27 arranged in the circumferential area of the surface of the drive disk 25 can periodically drive the drive gear 26 to rotate. The drive gear 26 periodically drives the rotating gear ring 21 to rotate, thereby indirectly driving the scanner 24 to rotate periodically, so that the scanner 24 is stationary for acquisition after rotation, providing time for acquisition and data processing noise reduction transmission; by setting the drive disk 25, the drive gear 26 and the rotating gear ring 21, the drive disk 25 drives the rotating gear ring 21 to rotate periodically by a specified angle. Compared with manual control of the lens rotation, the accuracy is higher, and the radii of the drive disk 25 and the drive gear 26 and the number of meshing teeth 27 on the surface can be adjusted to indirectly adjust the angle of periodic rotation of the rotating gear ring 21 and adjust the rotation angle of the scanner 24.

[0027] The above has described a specific embodiment of the present utility model in detail, but the content described is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. Any equivalent changes and improvements made within the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
