Description
A monitoring device for unmanned bucket wheel excavators Technical Field
[0001] This utility model relates to the field of bucket wheel excavator monitoring technology, specifically to a monitoring device for an unmanned bucket wheel excavator. Background Technology
[0002] During the operation of thermal power plants, bucket wheel excavators are used to transport coal. With the improvement of automation levels, fully automatic unattended systems for bucket wheel excavators in thermal power plants have been applied. These systems integrate technologies such as automatic control and 3D scanning to establish digital stockpile information and configure comprehensive monitoring equipment to monitor the working status and process of the bucket wheel excavators, facilitating timely adjustments to their operation. The monitoring devices in these unattended systems typically operate in the coal yard, where dust frequently accumulates on their lenses. While existing fully automatic unattended monitoring devices can clean the lenses to some extent to ensure clarity, they lack automatic cleaning cloth replacement. This results in the cleaning cloth becoming less effective after repeated use due to surface contamination, and may even cause the lens to become more blurry due to dirt accumulation, requiring frequent disassembly and cleaning by workers. Summary of the Invention

Detailed Implementation
[0018] Referring to Figures 1 to 5, this utility model provides a monitoring device for an unmanned bucket wheel excavator, comprising: a mounting frame 1, which is fixedly connected to the end face of the monitor body 15; the inner side of the mounting frame 1 is movably connected to the main lead screw 14 via bearings; the outer side of the mounting frame 1 is fixedly connected to the main motor 9 and the main control component 13; the output shaft of the main motor 9 is connected to the main lead screw 14 via a coupling; the surface of the moving plate 5 is fixedly connected to the main slider 12, the auxiliary slider 3, and the auxiliary control component 6; the main slider 12 is screwed to the main lead screw 14 through a threaded hole; the upper end face of the moving plate 5 is fixedly connected to the auxiliary motor 11; the lower end face of the moving plate 5 is fixedly connected to the electric rod 2; the telescopic rod of the electric rod 2 is fixedly connected to the buffer rod 17; the buffer rod 17 is slidably connected to the fitting column 18 via a spring; the lower end face of the moving plate 5 is movably connected to the positioning shaft 19 via bearings; and the cleaning roller 16 is movably connected to the inner cavity of the moving plate 5 via the positioning shaft 19 and the auxiliary motor 11.
[0019] In this embodiment, during daily use of the unmanned bucket wheel excavator monitoring device in the coal yard, dust is easily stirred up due to the operation of the bucket wheel excavator. This dust easily adheres to the lens of the monitoring unit 15 in the monitoring device, resulting in blurry monitoring images. At this time, the worker sends a corresponding signal to the wireless transceiver module in the main control component 13 through an external controller (not shown in the figure). The main control component 13 then starts the electrically connected main motor 9. The output shaft of the main motor 9 drives the main lead screw 14 to rotate synchronously through a coupling. The main lead screw 14, through the screwed main slider 12, can synchronously push the moving plate 5 and the cleaning roller 16 to move. Then, the cleaning cloth fixedly connected to the surface of the cleaning roller 16 can slide against the lens surface of the monitoring unit 15, thereby cleaning the lens of the monitoring unit 15. During the movement of the moving plate 5, the main trigger 8 set in the movement direction of the mounting frame 1 is triggered. The main trigger 8 sends a signal to the electrically connected main control component 13. Then, the main control component 13 shuts down the main motor 9. At the same time as the moving plate 5 triggers the main trigger 8, the moving plate 5 moves... The secondary trigger 7, located on the side of plate 5, is synchronously triggered by the inner side of mounting frame 1. The secondary trigger 7 then sends a signal to the electrically connected secondary control component 6. The secondary control component 6 then first activates the electric rod 2. The telescopic rod of the electric rod 2 retracts and then extends, completing one cycle. During the retraction of the electric rod 2, the buffer rod 17, fixedly connected to the telescopic rod of the electric rod 2, drives the locking post 18 to move synchronously. The locking post 18 then disengages from the locking hole on the end face of the cleaning roller 16, releasing the restriction between the moving plate 5 and the cleaning roller 16. When the auxiliary motor 11, which is electrically connected, is started, the output shaft of the auxiliary motor 11 drives the cleaning roller 16 to rotate at low speed through the connector. Then, when the buffer rod 17 pushes the fitting post 18 to abut against the end face of the cleaning roller 16 again, the fitting hole of the next set on the surface of the cleaning roller 16 will be aligned with the fitting post 18 in the rotation direction. Thus, the fitting post 18 can be smoothly inserted into the new fitting hole. This can not only complete the automatic replacement of the cleaning surface of the cleaning roller 16, but also ensure the stability of the connection between the cleaning roller 16 and the moving frame. The auxiliary control component 6 and the main control component 13 are electrically connected.
[0020] In a preferred embodiment, the movable plate 5 has a rectangular structure and is composed of an upper horizontal plate, a base plate and a lower horizontal plate. The end face of the base plate has a U-shaped structure, while the upper and lower horizontal plates have square structures. At the same time, the size of the inner cavity of the base plate is larger than the size of the cleaning roller 16.
[0021] In this embodiment, as shown in Figures 2 and 5, the size of the inner cavity of the substrate is set so that the cleaning roller 16 can rotate smoothly, thereby facilitating the automatic adjustment of the cleaning surface of the cleaning roller 16 and ensuring that the cleaning roller 16 can wipe the lens of the monitor body 15 with a new cleaning surface.
[0022] In a preferred embodiment, a buffer groove is provided on the surface of the lower horizontal plate at the lower end of the movable plate 5. The buffer groove has a cylindrical structure, and the opening at the lower end of the buffer groove is directly opposite the telescopic rod of the electric rod 2. The slidingly connected fitting column 18 inside the buffer groove has a cylindrical structure, and the upper end of the fitting column 18 has a frustum-shaped structure.
[0023] In this embodiment, as shown in Figures 3, 4 and 5, the buffer groove and the fitting column 18 are matched in size, which can help enhance the stability of the fitting column 18 when it moves. The upper end of the fitting column 18 has a frustum-shaped structure, which can help reduce the difficulty of the fitting column 18 being embedded in the fitting hole and improve the convenience of the fixed connection between the moving plate 5 and the cleaning roller 16.
[0024] In a preferred embodiment, an adjustment groove is provided at the lower end of the fitting column 18. The axial section of the adjustment groove is convex, and a spring is fixedly connected to the top of the inner cavity of the adjustment groove. Meanwhile, a buffer rod 17 is slidably connected to the opening at the lower end of the inner cavity of the adjustment groove. The axial section of the buffer rod 17 is T-shaped, and the size of the upper end of the buffer rod 17 matches that of the opening of the adjustment groove.
[0025] In this embodiment, as shown in Figures 3 and 4, the opening of the adjustment groove can help enhance the stability when the buffer rod 17 compresses the spring. The spring is also designed so that when the electric rod 2 pushes the fitting post 18 to reset through the buffer rod 17, the fitting post 18 can abut against the end face of the cleaning roller 16 and stop moving before the new fitting hole on the end face of the cleaning roller 16 moves to the appropriate position. Therefore, the spring can play a mutual buffering role. When the new fitting hole is directly opposite the fitting post 18, the fitting post 18 can be quickly embedded into the new fitting hole under the action of the compressed spring, thereby completing the fixed connection between the moving plate 5 and the cleaning roller 16.
[0026] As a preferred embodiment, the mounting frame 1 has a U-shaped structure. Two sets of main triggers 8 are symmetrically connected to the inner side of the mounting frame 1, and two sets of secondary triggers 7 are symmetrically connected to the two sides of the outer side of the moving plate 5. The main triggers 8 and secondary triggers 7 are staggered. At the same time, the main slider 12 and the secondary slider 3 fixedly connected to the surface of the moving plate 5 are both square on the outside and circular on the inside.
[0027] In this embodiment, as shown in Figures 1 and 2, the configuration of the main trigger 8 and the secondary trigger 7 enables the main motor 9 and the secondary motor 11 to start or stop at fixed points. It also ensures that the cleaning surface of the cleaning roller 16 automatically rotates and is replaced with a new cleaning surface after one cleaning cycle, thereby improving the cleaning effect of the cleaning roller 16 on the lens of the monitor body 15.
[0028] In a preferred embodiment, a guide rod 4 is fixedly connected to the inner side of the mounting frame 1 at the position relative to the through hole of the auxiliary slider 3. The auxiliary slider 3 is slidably connected to the guide rod 4 through the through hole. Two sets of cleaning rings 10 are symmetrically connected to both sides of the main slider 12. Both sets of cleaning rings 10 are cylindrical in shape. At the same time, an annular cleaning brush is fixedly connected to the inner side of the cleaning ring 10. The cleaning brush abuts against the surface of the main lead screw 14.
[0029] In this embodiment, as shown in Figures 1 and 2, the guide rod 4 and the through hole are matched in size, which can help improve the stability of the auxiliary slider 3 and the moving plate 5 when they move. The cleaning rings provided on both sides of the main slider 12 can perform corresponding auxiliary cleaning on the surface of the main lead screw 14 through the cleaning brush on the inner side during the movement of the main slider 12 and the moving plate 5, thereby reducing the probability of transmission failure of the main lead screw 14. The cleaning brush is made of hard bristles.
[0030] In a preferred embodiment, the cleaning roller 16 has a regular hexagonal prism structure, and a cleaning cloth is fixedly connected to the surface of the cleaning roller 16. The middle of both ends of the cleaning roller 16 is provided with a fitting groove, and six sets of fitting holes are provided parallel and equally spaced along the circumferential direction at the edge of the end face of both ends of the cleaning roller 16. The upper end of the fitting post 18 is directly opposite a set of fitting holes. At the same time, the upper end of the positioning shaft 19 and the connecting part of the output shaft of the auxiliary motor 11 are both regular hexagonal structures, and the upper end of the positioning shaft 19 and the connecting part are adapted to the size of the fitting grooves provided at both ends of the cleaning roller 16.
[0031] In this embodiment, as shown in Figures 3 and 5, the polyhedral structure of the cleaning roller 16 allows the surface of the cleaning roller 16 to be divided into multiple sets of cleaning surfaces. Each time cleaning is performed, a new set of cleaning surfaces can be used for cleaning, which improves the cleaning effect of the lens of the monitor body 15 and extends the time interval for workers to disassemble and clean the cleaning roller 16. At the same time, the opening of the interlocking groove can help improve the efficiency of loading and unloading the cleaning roller 16.
[0032] The unmanned monitoring bucket wheel excavator monitoring device of this utility model, through the cooperation of the main motor 9, main lead screw 14, main slider 12, auxiliary motor 11, moving plate 5 and cleaning roller 16, enables the lens of the device to be wiped with a clean cleaning roller 16 each time it needs to be cleaned, thereby ensuring the cleanliness of the lens, extending the interval between disassembly and cleaning by workers, and reducing the labor intensity of workers. At the same time, the main control component 13 and the auxiliary control component 6 both adopt common brand models or devices with equivalent effects on the market.
