On the other side of each first mounting plate 11, a plurality of first sound and light alarms 10 are fixedly connected. The top of each first mounting bracket 9 and a corresponding second mounting bracket 13 is fixedly connected to a support plate 7. A plurality of second mounting plates 8 are fixedly connected between the two support plates 7. On the top of each second mounting plate 8, a plurality of second adjusting components 21 are fixedly connected. An adjusting knob 19 is threadedly connected to each first adjusting component 18 and second adjusting component 21. The telescopic end of each second adjusting component 21 is fixedly connected to a second distance sensor 6. On the bottom of each second mounting plate 8, a plurality of second sound and light alarms 5 are fixedly connected. A third sound and light alarm 12 is embedded in the side of each first base 1 and second base 14. A third sound and light alarm 12 is fixedly connected to the top of each first base 1 and second base 14.

[0019] Specifically, each first sound and light alarm 10 corresponds to a first distance sensor 4, and each second sound and light alarm 5 corresponds to a second adjusting component 21.

[0020] Specifically, a first level 16 is embedded in the opposite surfaces of the two support plates 7, and a second level 17 is embedded in the front of the two first bases 1 and the back of the two second bases 14. Each third sound and light alarm 12 corresponds to a second level 17.

[0021] Specifically, the first adjusting component 18 includes a sleeve 183, a mounting sleeve 181, a movable rod 182, and a stopper 184. The mounting sleeve 181 is fixedly installed in the sleeve 183. The movable rod 182 is inserted into the mounting sleeve 181. One end of the movable rod 182 located in the sleeve 183 is fixedly connected to the stopper 184. The free end of the movable rod 182 is fixedly connected to the first distance sensor 4. The structure of the second adjusting component 21 is exactly the same as that of the first adjusting component 18. The adjusting knob 19 is threadedly connected to the sleeve 183.

[0022] Specifically, a plurality of positioning screw holes 3 are formed in each of the first support rods 2 and the second support rods 20, and positioning bolts 15 are threadedly connected to the opposite surfaces of the two first mounting brackets 9 and the opposite surfaces of the two second mounting brackets 13. The threaded ends of each of the positioning bolts 15 are threadedly connected to the corresponding positioning screw holes 3.

[0023] Specifically, the first distance sensor 4, the second distance sensor 6, the first level 16, the second level 17, the first sound and light alarm 10, the second sound and light alarm 5, and the third sound and light alarm 12 are all externally connected to a control switch through wires.

[0024] The working principle and usage process of the present utility model: When in use, the device is arranged in a coal mine roadway. The two first mounting brackets 9 are close to the left side wall of the roadway, the two second mounting brackets 13 are close to the right side wall of the roadway, and the two support plates 7 are close to the top of the roadway. Then, the distances between the first distance sensor 4 and the second distance sensor 6 and the side wall and the top of the roadway can be adjusted through the first adjusting assembly 18 and the second adjusting assembly 21. When adjusting, the position of the first distance sensor 4 or the second distance sensor 6 can be adjusted by pulling the movable rod 182. After the adjustment is completed, the movable hanging rod is locked and fixed by adjusting the knob 19. If the top of the roadway is a flat top, the plurality of second distance sensors 6 can be adjusted to the same height. If the top of the roadway is an arched top, the plurality of second distance sensors 6 can be adjusted to different heights so that the distance between each second distance sensor 6 and the top of the roadway remains the same. In this way, the side wall and the top of the roadway can be monitored in real time. Once the roadway deforms, the first distance sensor 4 or the second distance sensor 6 at the corresponding position will immediately detect it. Therefore, the first sound and light alarm 10 or the second sound and light alarm 5 corresponding to the first distance sensor 4 or the second distance sensor 6 will immediately light up. And the externally connected control switch of the device is a PLC controller. When the first distance sensor 4 or the second distance sensor 6 detects the deformation of the roadway, it will immediately send a signal to the control switch, and the control switch will control the corresponding first sound and light alarm 10 or the second sound and light alarm 5 to light up, which is convenient for workers to notice and has high safety. The first level 16 can judge the level condition of the support plate 7, and the second level 17 can judge the level condition of the first base 1 and the second base 14, so as to judge whether the ground on both sides is flat. If the ground on one side sinks or bulges, both the first level 16 and the second level 17 will change. At this time, the control switch automatically controls the third sound and light alarm 12 to give an alarm, which has strong practicability.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
