[0030] The bottom end of the laser radar level meter body 5 is fixedly connected to a protective cover 7, one side of the inner wall of the protective cover 7 is fixedly connected to a nozzle 12, one side of the nozzle 12 is fixedly connected to a connecting pipe 11 that runs through the top of the mounting plate 10 through a conduit, and the lower end of the other side of the protective cover 7 is fixedly connected to an electric telescopic rod 8, and the output end of the electric telescopic rod 8 extends to the inside of the protective cover 7 and is fixedly connected to a slide plate 13, and the top of the slide plate 13 is fixedly connected to a cleaning brush 15, and the surface of the detection rod 9 is shielded by the protective cover 7 to reduce the adhesion of material dust on the surface and bottom of the detection rod 9. At the same time, the electric telescopic rod 8 can be started from time to time, so that the cleaning brush 15 slides to clean the bottom end of the detection rod 9, sweeping off the material dust adhered to the bottom end, and blowing air to the bottom end of the detection rod 9 through the nozzle 12 to further clean the bottom end of the detection rod 9.

[0031] In this embodiment, a material guide platform 14 is fixedly connected to the lower end of the inner wall of the protective cover 7. The material guide platform 14 is funnel-shaped. The funnel-shaped material guide platform 14 can be used to quickly guide the cleaned material dust so that it can be quickly discharged from the bottom of the protective cover 7.

[0032] In this embodiment, the protective cover 7 is trumpet-shaped, and the top of the protective cover 7 is fixedly connected to the bottom of the laser radar level meter body 5. The trumpet-shaped protective cover 7 is used to shield the surface of the detection rod 9 to reduce the adhesion of material dust on the surface and bottom of the detection rod 9.

[0035] On the basis of Example 1, a preferred embodiment of the grinding mill position detection and early warning device provided by the present utility model is as follows: Figures 1 to 6 As shown: the mounting assembly 4 includes a slot 401, which is opened at an equal angle on the inner wall of the mounting seat 2, and rotating plates 405 are rotatably connected to both sides of the top of the slot 401, and a clamping block 402 is fixedly connected to the surface of the mounting disk 10 at an equal angle, and fixed blocks 403 are fixedly connected to both sides of the top of the mounting disk 10. The clamping block 402 is engaged with the inside of the slot 401 to achieve the engagement and fixation of the mounting disk 10 and the inside of the mounting seat 2, and then the rotating plate 405 is rotated to engage with the inner wall of the fixed block 403, and then the elastic sheet 404 is used to improve the firmness of the rotating plate 405 to engage with the inner wall of the fixed block 403, so as to realize the rapid disassembly and assembly of the laser radar level meter body 5.

The inverted L-shaped fixing block 403 facilitates its engagement with the rotating plate 405 to achieve the engagement and fixation of the mounting disk 10.

[0038] In this embodiment, an elastic sheet 404 is fixedly connected to the inner top wall of the fixed block 403. The cross-section of the elastic sheet 404 is a right-angled trapezoid. The right-angled trapezoidal elastic sheet 404 is used to improve the tightness of the engagement and fixation between the rotating plate 405 and the fixed block 403.

[0039] In addition, a sealing ring 16 is fixedly connected to the upper end of the surface of the protective cover 7. The cross-sectional area of ​​the sealing ring 16 is equal to the cross-sectional area inside the through groove 6.

At this time, the elastic sheet 404 is used to improve the firmness of the rotating plate 405 clamped to the inner wall of the fixed block 403, so that the laser radar level meter body 5 can be quickly disassembled and assembled. When the laser radar level meter body 5 needs to be disassembled and maintained, the rotating plate 405 can be rotated to be completely separated from the fixed block 403, and then the laser radar level meter body 5 is pulled up with force to take it out through the through slot 6 as a whole to achieve disassembly. After the first bolt fixing, the laser radar level meter body 5 can be quickly disassembled and assembled for maintenance or replacement, avoiding the cumbersome inconvenience caused by the traditional bolt fixing caused by each disassembly and assembly of the bolts;

[0041] Afterwards, the height of the material inside the silo 1 can be detected by the cooperation of the laser radar level meter body 5 and the detection rod 9. As long as the material level in the silo 1 reaches a certain height, it will be detected by the laser radar level meter body 5, and then the alarm light 3 will be activated to emit an alarm light, thereby reminding the staff to make adjustments to avoid overflowing of the material.

[0042] At the same time, during its use, the protective cover 7 can be used to shield the surface of the detection rod 9 to reduce the adhesion of material dust on the surface and bottom of the detection rod 9. At the same time, the electric telescopic rod 8 can be started from time to time to drive the slide plate 13 to slide, so that the cleaning brush 15 slides to clean the bottom of the detection rod 9, and the material dust adhered to the bottom of the detection rod 9 is swept off. The nozzle 12 can be used to blow air to the bottom of the detection rod 9 to further clean the bottom of the detection rod 9 to avoid the adhesion of material dust and affect the accuracy of laser radar detection. The funnel-shaped material guide platform 14 can quickly guide the cleaned material dust to facilitate its rapid discharge from the bottom of the protective cover 7.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
