The coal yard inspection robot of this invention has a simple structure, is easy to manufacture, and is convenient for implementation and widespread application.

[0003] In dusty environments, the optical components of the aforementioned and existing lidar collision avoidance technologies are easily covered by dust. Dust accumulation interferes with laser emission and reception, leading to a significant decrease in detection accuracy. This prevents the collision avoidance device from detecting surrounding obstacles in a timely and accurate manner, thereby increasing the risk of collision accidents involving bucket wheel stacker-reclaimers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where optical components are easily covered by dust, and to propose a laser radar anti-collision device for bucket wheel stacker-reclaimers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lidar anti-collision device for a bucket wheel stacker-reclaimer, comprising a lidar body, with grooves on both sides of the lidar body, a fixed frame on one side of each groove, an electric telescopic rod on one side of the lidar body, a sleeve on the side of the lidar body away from the electric telescopic rod, a guide rod inside the sleeve, a movable frame at the bottom of the electric telescopic rod, a brush on the side of the movable frame near the lidar body, an air pump at the bottom of the lidar body, an air jet pipe on one side of the air pump, and sliders on both ends of the movable frame.

[0006] Preferably, the two grooves are mirror images of the lidar body, the movable frame is integrally formed with the two sliders, and the two sliders of the movable frame are installed in the grooves on the surface of the lidar body. The brush is installed on the surface of the movable frame and is bolted to the movable frame.

[0007] Preferably, both mounting brackets are mounted on the surface of the lidar body, and the two mounting brackets are mirror images of the lidar body, with the lidar body as the center. Both mounting brackets are bolted to the lidar body.

[0008] Preferably, the electric telescopic rod and the sleeve are both mounted on the surfaces of two fixed frames, and both the electric telescopic rod and the sleeve are bolted to the fixed frames.

[0009] Preferably, the guide rod is installed inside the sleeve, one end of the movable frame is bolted to the electric telescopic rod, and the other end of the movable frame is bolted to the bottom end of the guide rod.

[0010] Preferably, the jet pipe is installed on the bottom surface of the lidar body and bolted to the lidar body, and the jet pipe is perpendicular to the brush.

[0011] Preferably, the air pump is installed on the bottom surface of the lidar body and is bolted to the lidar body, and the air pump is connected to the jet pipe.

[0012] Beneficial effects

[0013] In this invention, when the lidar main body is in use, the electric telescopic rod is opened by the lidar main body control system, causing the electric telescopic rod to extend and retract downwards and push the moving frame. The moving frame moves downwards, and the optical components on the surface of the lidar main body are cleaned by brushes on the surface of the moving frame. At the same time as the brushes are cleaning, the lidar main body control system turns on the air pump, which delivers air into the air jet pipe. The air jet pipe blows air onto the surface of the lidar main body, thereby blowing away the dust cleaned by the brushes and completing the cleaning of the lidar main body. This solves the problem that the optical components are easily covered by dust. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 A lidar anti-collision device for a bucket wheel stacker-reclaimer includes a lidar body 1. Both sides of the lidar body 1 are provided with grooves 2. A fixed frame 5 is provided on one side of each groove 2. An electric telescopic rod 6 is provided on one side of the lidar body 1. A sleeve 7 is provided on the side of the lidar body 1 away from the electric telescopic rod 6. A guide rod 8 is provided inside the sleeve 7. A movable frame 9 is provided at the bottom of the electric telescopic rod 6. A brush 10 is provided on the side of the movable frame 9 closest to the lidar body 1. An air pump 4 is provided at the bottom of the lidar body 1. An air jet pipe 3 is provided on one side of the air pump 4. Slider blocks 11 are provided on the surfaces of both ends of the movable frame 9. The two grooves 2 are mirror images of the lidar body 1. The movable frame 9 and the two sliders 11 are integrally formed, and the two sliders 11 of the movable frame 9 are installed in the grooves 2 on the surface of the lidar body 1. The brush 10 is installed on the movable frame 9. The surface of the laser radar body 1 is bolted to the brush 10 and the movable frame 9. Two fixed frames 5 are installed on the surface of the laser radar body 1 and are mirror images of the laser radar body 1. Both fixed frames 5 are bolted to the laser radar body 1. The electric telescopic rod 6 and the sleeve 7 are installed on the surface of the two fixed frames 5 and are bolted to the fixed frames 5. The guide rod 8 is installed inside the sleeve 7. One end of the movable frame 9 is bolted to the electric telescopic rod 6 and the other end of the movable frame 9 is bolted to the bottom end of the guide rod 8. The jet pipe 3 is installed on the bottom surface of the laser radar body 1 and is bolted to the laser radar body 1. The jet pipe 3 is perpendicular to the brush 10. The air pump 4 is installed on the bottom surface of the laser radar body 1 and is bolted to the laser radar body 1. The air pump 4 is connected to the jet pipe 3.

[0024] The lidar body 1, as the core component, incorporates a laser emission and reception system. It emits laser beams and receives reflected laser signals, calculating parameters such as the laser's time of flight to detect the distance and orientation of surrounding objects, thus achieving collision avoidance. The slide 2 provides a sliding track for the slider 11, restricting the movement direction of the moving frame 9, ensuring it can only slide up and down along the side of the lidar body 1. This guarantees that the brush 10 can accurately clean the surface of the lidar body 1 during cleaning, preventing deviation. The fixing frame 5 secures the electric telescopic rod 6 and the sleeve 7, ensuring the stability of these two components during operation and enabling them to function properly. When the electric telescopic rod 6 is powered on, the internal motor drives the lead screw to rotate, causing the lead screw nut to move linearly along the lead screw, thereby extending and retracting the telescopic rod and pushing the moving frame 9 up and down along the slide 2. This allows the brush 10 to contact the optical components on the surface of the lidar body 1 for cleaning. Sleeve 7 provides guidance and support for guide rod 8. When electric telescopic rod 6 pushes moving frame 9, guide rod 8 slides inside sleeve 7, assisting moving frame 9 in maintaining linear motion and preventing it from swaying or tilting during movement, ensuring the stability and accuracy of brush 10 cleaning operation. Moving frame 9 is integrally formed with slider 11. Under the push of electric telescopic rod 6, slider 11 slides in slide groove 2, driving brush 10 mounted on its surface to move up and down, realizing the cleaning operation on the surface of lidar body 1. Brush 10 is bolted to moving frame 9. Driven by moving frame 9, it physically brushes away optical components on the surface of lidar body 1, initially cleaning the dust attached to it. After the air pump 4 is powered on, the internal impeller rotates at high speed, creating a vacuum inside the pump. External air is drawn into the pump under atmospheric pressure, then compressed and transported through pipe to jet pipe 3, providing jet pipe 3 with a certain pressure airflow. The jet pipe 3 is connected to the air pump 4. The compressed air output by the air pump 4 is ejected through the jet pipe 3, forming an airflow that blows onto the surface of the lidar body 1, blowing away the dust cleaned by the brush 10, thus completing the cleaning of the lidar body 1.

[0025] It is important to note that the laser radar body 1 of the lidar collision avoidance device emits a laser beam through its internal laser emitting system. When this laser beam encounters an object, it is reflected, and the reflected beam is received by the laser receiving system. The lidar body 1 calculates the distance between the object and the lidar by precisely measuring the time difference between laser emission and reception, combined with the laser's propagation speed. Simultaneously, it determines the object's orientation based on information such as the laser beam's emission angle. When the detected object is less than a pre-set safe distance, the lidar collision avoidance device will issue an alarm signal, alerting the operator or automatically triggering braking measures in relevant equipment to prevent collisions. Specific Implementation Example 2:

[0027] Reference Figure 1-4 A lidar anti-collision device for a bucket wheel stacker-reclaimer is further based on the basic structure in Specific Embodiment 1. When the lidar body 1 operates in a dusty environment for a period of time, dust may adhere to the optical components on its surface, affecting detection accuracy. At this time, the control system of the lidar body 1 initiates a cleaning program, opens the electric telescopic rod 6, extends the electric telescopic rod 6 and pushes the moving frame 9. The sliders 11 at both ends of the moving frame 9 move downward along the slide groove 2, causing the brush 10 to contact the surface of the lidar body 1 and brush it, performing preliminary cleaning of the dust on the optical components. At the same time, the control system turns on the air pump 4, which compresses air and delivers it into the air jet pipe 3. The air jet pipe 3 sprays airflow onto the surface of the lidar body 1, blowing away the dust cleaned by the brush 10, thereby cleaning the surface of the lidar body 1 and ensuring that its optical components can work normally.

[0028] In summary:

[0029] 1. When using the lidar main body 1, the control system of the lidar main body 1 opens the electric telescopic rod 6, causing the electric telescopic rod 6 to extend and retract downwards and push the moving frame 9. The moving frame 9 moves downwards, and the brush 10 on the surface of the moving frame 9 brushes and cleans the optical components on the surface of the lidar main body 1. At the same time as the brush 10 is cleaning, the control system of the lidar main body 1 turns on the air pump 4, which delivers air into the air jet pipe 3. The air jet pipe 3 blows air onto the surface of the lidar main body 1, thereby blowing away the dust cleaned by the brush 10 from the lidar main body 1, thus completing the cleaning of the lidar main body 1 and solving the disadvantage that the optical components are easily covered by dust.
