In actual use, the staff starts the rotating cylinder 202, and drives the first turntable 203 to rotate through the drive of the rotating cylinder 202. Since the first turntable 203 is connected to the second turntable 204 through a belt, and the second turntable 204 is installed on the upper surface of the monitoring bracket 101 through a turntable bearing 205, the second turntable 204 rotates synchronously with the first turntable 203. The rotation of the second turntable 204 drives the support arm 303 to rotate, and then drives the fixed plate 305 installed on the upper end of the support arm 303 and the monitoring and early warning box 500 to rotate, thereby realizing the rotation monitoring of the monitoring and early warning box 500.

[0026] By cooperating with multiple parts in the rotating assembly 200, rotational monitoring of the monitoring early warning box 500 can be realized. The rotating monitoring equipment can cover a wider area of ​​the goaf, reduce monitoring blind spots caused by fixed installation, and achieve 360-degree blind-spot monitoring of the goaf.

[0027] Second embodiment:

[0028] like Figure 3-4 As shown, the adjustment component 300 also includes a hydraulic cylinder 301 installed on the monitoring bracket 101, and a pushing rod 302 is provided at the output end of the hydraulic cylinder 301. The pushing rod 302 is located in the middle of the support arms 303 at both ends, and the support arms 303 are a retractable structure. In actual use, by starting the hydraulic cylinder 301, the driving of the hydraulic cylinder 301 drives the pushing rod 302 to move upward, and the upward pushing of the pushing rod 302 causes the support arms 303 at both ends to retract. Through the retraction of the support arms 303, the monitoring and early warning box 500 can monitor gases at different heights while rotating.

[0029] By using multiple parts in the adjustment component 300 in coordination, the monitoring and early warning box 500 can monitor gases at different altitudes.

[0034] By using the connecting block 304 in conjunction with the connecting seat 306, the fixed plate 305 can be detachably installed. At the same time, the connecting block 304 provided at the end of the push rod 302 and the connecting block 304 provided at the output end of the hydraulic cylinder 301 are connected by positioning bolts, so that the push rod 302 can be stably connected, thereby ensuring the stable lifting and lowering of the push rod 302.

[0035] Fifth embodiment:

[0036] like Figure 1-2 As shown, a collecting component 400 is also provided in the monitoring bracket 101, and the collecting component 400 includes an air suction box 401.

[0040] By using the positioning holes provided in the monitoring and early warning box 500 in conjunction with the holder 307 , the monitoring and early warning box 500 can be quickly installed by pre-tightening the bolts, thereby facilitating subsequent maintenance of the monitoring and early warning box 500 .

[0041] Working principle: In actual use, the staff starts the rotating cylinder 202, and the first turntable 203 is driven to rotate by the rotating cylinder 202. Since the first turntable 203 and the second turntable 204 are connected by a belt, and the second turntable 204 is installed on the upper surface of the monitoring bracket 101 through the turntable bearing 205, the second turntable 204 rotates synchronously with the first turntable 203. The rotation of the second turntable 204 drives the support arm 303 to rotate, and then drives the fixed plate 305 and the monitoring and early warning box 500 installed on the upper end of the support arm 303 to rotate, thereby realizing the rotation monitoring of the monitoring and early warning box 500. At the same time, by starting the hydraulic cylinder 301, the hydraulic cylinder 301 drives the push rod 302 to move upward, and the push rod 302 pushes upward, so that the support arms 303 at both ends are extended and retracted. Through the extension and retraction of the support arms 303, the monitoring and early warning box 500 can monitor gases at different heights while rotating.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
