[0002] A laser scanning device is a system that detects the position, speed and other characteristic quantities of a target by emitting a laser beam. Its working principle is to emit a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the emitted signal. After appropriate processing, relevant information of the target can be obtained. It consists of a laser transmitter, an optical receiver, a turntable and an information processing system, etc. The laser transmitter converts the electrical pulse into an optical pulse and emits it. The optical receiver then restores the optical pulse reflected from the target into an electrical pulse and sends it to the display to facilitate the control of parameters such as the distance, azimuth, height, speed, attitude, and even shape of the target.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3 , an embodiment provided by the present utility model: A laser scanning device, including a support main body 1, a quadrilateral adjustment mechanism 2 is arranged outside the support main body 1, the quadrilateral adjustment mechanism 2 is evenly installed around the outer diameter of the support main body 1 at intervals of 120 degrees, a moving crawler 3 is installed on the quadrilateral adjustment mechanism 2, a main control box 4 is fixed at the front end of the support main body 1, a wireless communication device 5 is installed on the top of the main control box 4, the wireless communication device 5 is wirelessly connected to a remote display platform 8, a three - phase synchronous rotation mechanism 6 is arranged at the front end of the main control box 4, a laser scanner 7 is arranged on the three - phase synchronous rotation mechanism 6, and a positioning module 71 is installed on the laser scanner 7;

[0021] Combined with the above-mentioned structural features, when the utility model is working, the quadrilateral adjustment mechanism 2 cooperates with the moving crawler 3 to adapt to pipes with different inner diameters, and can move steadily inside the pipe by itself. Through the three-phase synchronous rotation mechanism 6 and the laser scanner 7, the inside of the pipe can be scanned in all directions, and the phenomenon of data loss can be effectively reduced. The scanning effect is good. The scanned data is summarized in the main control box 4 for filtering, isolation, and amplification processing to make the data smoother. It is then sent to the remote display platform 8 through the wireless communication device 5 for visual display, which is convenient for operators to understand the information in the pipeline. At the same time, when the device moves forward, the position of the laser scanner 7 can be located in real time through the positioning module 71, which is convenient for operators to understand the scanning dynamics and has strong practicality.

[0022] See also Figures 1 - 3 The quadrilateral adjustment mechanism 2 includes a front articulated seat 21 and a rear articulated seat 22, which are fixed on the outside of the support body 1. A front support link 23 is rotatably installed on the front articulated seat 21, and a rear support link 24 is rotatably installed on the rear articulated seat 22. The front support link 23 and the rear support link 24 are connected by a movable track 3 to ensure synchronous movement. The front articulated seat 21 and the rear articulated seat 22 are provided with an adjustment disk 26, which is slidably connected to the support body 1, and a spring 27 is provided between the adjustment disk 26 and the rear articulated seat 22. An adjustment link 25 is rotatably provided on the adjustment disk 26, and the end of the adjustment link 25 is hinged to the front support link 23.

[0023] See also Figures 1 - 3 The mobile crawler 3 includes a rotating roller 31, which is respectively mounted at the ends of the front supporting link 23 and the rear supporting link 24, and is rotatably connected to the front supporting link 23 and the rear supporting link 24.

[0024] In combination with the above-mentioned structural features, when the utility model is working, the device is inserted from the pipe mouth, and the front supporting link 23 is rotated backward by the squeezing force of the pipe mouth, driving the movable crawler 3 to shrink inward. At this time, the adjusting link 25 presses the adjusting disk 26 backward to make it move backward. When the device completely enters the pipe, the spring 27 set at the rear end of the adjusting disk 26 provides a forward pushing force, which is transmitted to the front supporting link 23 through the adjusting link 25, making it rotate clockwise, driving the movable crawler 3 to fit tightly against the inner wall of the pipe, starting the driving motor 33, driving the rotating roller 31 and the connecting crawler 34 to move, realizing the movement of the device in the pipe, and the movable crawler 3 is supported by three points, and the movement is stable.

[0026] Combined with the above structural features, when the utility model works, the second driving motor 64 is started to drive the planet gear 62 to rotate around the sun gear 61, and at the same time drive the connecting housing 63 to rotate synchronously around the main shaft. Three laser scanners 7 are installed on the connecting housing 63, which can perform multiple scans on the inner wall of the pipeline, and compensate for defective data with each other through algorithms to make the scan results more accurate.

[0027] Working principle: When the utility model is in use, through the quadrilateral adjustment mechanism 2 and the moving crawler 3, it can adapt to pipelines with different inner diameters and can move steadily inside the pipeline by itself. Through the three-phase synchronous rotating mechanism 6 and the laser scanner 7, it can perform a full-range scan on the inside of the pipeline, and effectively reduce the phenomenon of data loss. The scanning effect is good. The scanned data is summarized in the main control box 4 for filtering, value isolation, and amplification processing to make the data smoother, and then sent to the remote display platform 8 through the wireless communication device 5 for visual display, which is convenient for the operator to understand the information inside the pipeline. At the same time, when the device moves forward, the position of the laser scanner 7 can be real-time positioned through the positioning module 71, which is convenient for the operator to understand the scanning dynamics and has strong practicability.
