[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figure 1-5As shown, the present invention provides a mine tunnel roof delamination monitoring device with strong dustproof ability, including a support frame 1, the bottom of the support frame 1 is fixed on a base 21, and the base 21 is provided with a mounting screw hole, which can be matched with the mounting screw hole by bolts to fix the base 21 on the tunnel bottom plate, thereby fixing the entire mine tunnel roof delamination monitoring device. Mounting grooves 2 are provided on both sides of the support frame 1, and mounting frames 3 are installed on both ends of the mounting grooves 2. Both sides of the top of the mounting frame 3 are arc-shaped, and the diameter of the arc is equal to the diameter of the arc at the top of the mounting groove 2. When installing the mounting frame 3, the mounting frame 3 and the mounting groove 2 can fit together, so that the mounting frame 3 is installed more firmly. Two adjacent mounting frames 3 are connected by bolts 4, and the two bolts 4 pass through the two ends of the support plate 5 respectively. Anti-deformation grooves 17 are evenly provided on the top and bottom surfaces of the support plate 5. The length of the anti-deformation grooves 17 is equal to the width of the support plate 5 to prevent the support plate 5 from being deformed due to the installation time of the support frame 1 for too long, thereby causing the monitoring device to malfunction. Rubber plates 6 are bonded to the two ends of the top surface of the support plate 5, and screw rods 7 are evenly welded in the middle of the support plate 5. Nuts 8 are installed in the middle of the screw rods 7 through threads. A mounting plate 9 is installed between the two nuts 8. The mounting plate 9 A power connection box 10 is installed in the middle of the top surface, and a support bar 11 is welded inside the top of the power connection box 10. A mercury box 12 is fixedly installed on the top surface of the support bar 11. The diameter of the mercury box 12 is smaller than the diameter inside the power connection box 10. A corresponding hole 16 is opened on the top surface of the support plate 5 corresponding to the power connection box 10. The diameter of the corresponding hole 16 is equal to the diameter of the power connection box 10. The power connection box 10 is fixedly installed inside the corresponding hole 16 to prevent the power connection box 10 from shaking in the corresponding hole 16. The horizontal plane of the top surface of the mercury box 12 is lower than the horizontal plane of the top surface of the support frame 1, so that mercury can enter the power connection box 10 after the mercury box 12 is broken. A battery 13 is installed at one end of the top surface of the mounting plate 9, and a connecting line 14 is installed at one end of the battery 13. One end of the connecting line 14 is inside the power connection box 10. An indicator light 15 is installed on one side of the top of the support frame 1, and one end of the indicator light 15 is connected to the power connection box 10 through the connecting line 14.

[0027] A dust cover 18 is installed on the top of the support frame 1. A mounting hole is opened in the dust cover 18 corresponding to the mounting frame 3, and the length of the mounting hole is equal to the length of the top surface of the mounting frame 3 to prevent dust from leaking in from the gap between the dust cover 18 and the mounting frame 3, so that the dust cover 18 can be easily installed on the outside of the mounting frame 3. Rubber rods 19 are bonded at both ends of the middle part of the dust cover 18, and both ends of the dust cover 18 are connected to the mounting frame 3 through screws 20.

[0028] The working principle and use process of the present invention are as follows:

[0029] The mounting frame 3 is installed on the mounting groove 2, and the two mounting frames 3 are fixed by rotating the bolts 4, thereby fixing the support plate 5, and the arc edge of the mounting frame 3 is matched with the arc edge of the mounting groove 2 through the rubber plate 6, so that the mounting frame 3 is fixed more firmly, thereby fixing the junction box 10 to prevent the junction box 10 from shaking and affecting the value of the separation layer detection.

[0030] After the support plate 5 is fixed, the mounting plate 9 is installed on the screw rod 7, and the nut 8 is rotated to fix the mounting plate 9 between the two nuts 8, thereby fixing the mounting plate 9, and thus fixing the battery 13, the mercury box 12 and the power connection box 10. When the delamination amount is small and the pressure is insufficient, the mercury box 12 is not broken, the two connecting wires 14 are not connected, and the indicator light 15 is not on. When the roof of the mine tunnel is delaminated and the pressure generated is too large, the support frame 1 is pressed down to break the mercury box 12. At this time, the mercury in the mercury box 12 falls into the power connection box 10, so that the two connecting wires 14 are connected, and the indicator light 15 is on, so that the staff can react quickly and escape, thereby improving the safety factor of the staff during construction.

[0031] After the monitoring device is installed, the dust cover 18 is installed on the mounting frame 3 through the screw 20 to prevent excessive accumulation of dust on the monitoring device, which may cause the monitoring device to malfunction. The rubber rod 19 is used to enhance the sealing between the dust cover 18 and the support frame 1, so that the dustproof effect is better.

[0032] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
