[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] according to Figures 1 to 9As shown, in the first aspect of the present disclosure, there is provided a roof delamination instrument 1, which is used to detect the delamination situation inside the rock layer 4, so as to prevent the top rock layer 4 from collapsing and causing safety accidents during the excavation of the mine. The roof delamination instrument 1 includes a delamination instrument body 2 and a detection mechanism. The delamination instrument body 2 is provided with an anchor claw 280 for connecting with the side wall surface of the rock formation hole 410 to fix the delamination instrument body 2 in the rock formation hole 410. The detection mechanism includes a first signal output device 230 and a signal receiving device 240 respectively arranged at opposite ends of the delamination instrument body, so that the signal receiving device 240 of one roof delamination instrument 1 can receive the signal sent by the first signal output device 230 of another roof delamination instrument 1, so as to detect the distance between the two roof delamination instruments 1.

[0039] Through the above technical scheme, a first signal output device 230 and a signal receiving device 240 are respectively arranged at the opposite ends of the delamination instrument body 2, and the distance between the two roof delamination instruments 1 can be monitored in real time through signal transmission. If the rock layer 4 of the roof collapses, the roof delamination instrument 1 located in the deep layer of the rock layer hole 410 is forced to move toward the opening of the rock layer hole 410. In this way, the relative position distance between the two roof delamination instruments 1 is reduced, and the information is fed back in real time through the detection mechanism, so that the staff can take timely response measures to prevent safety accidents. Through signal transmission, the readings are more accurate, faster, and more reliable.

[0040] The number of roof separation instruments 1 can be adjusted adaptively according to the actual needs. Figure 1 As shown, if the rock layer 4 to be detected has three different delamination conditions, the number of the roof delamination instruments 1 can be three accordingly. The present disclosure is not limited thereto.

Through such a setting, the signal transmission data between the two top plate delamination instruments 1 can be made more accurate.

[0042] The position limitation of the first signal output device 230 and the signal receiving device 240 in the present disclosure is only for the present disclosure. The positions of the first signal output device 230 and the signal receiving device 240 can be adaptively adjusted according to the needs of actual conditions.

The infrared receiving module 242 is used to receive the optical signal emitted by the infrared transmitting module 231, and the infrared ranging module 241 is used to convert the speed information of the optical signal received by the infrared receiving module 242 into distance information. The first lens 244 and the second lens 233 are provided to prevent the first shell 245 and the second shell 234 from interfering with the optical signal emitted by the infrared transmitting module 231, so as to ensure that the infrared receiving module 242 can accurately receive the optical signal.

[0054] Optionally, the data transmission device 3 may include a data acquisition line 310 and a display screen 320 connected to the data acquisition line 310, and the data acquisition line 310 is connected to the second signal output device 120 and the signal receiving device 240 in sequence, and is used to output the signal received by the signal receiving device 240 to the display screen 320, so that the operator can intuitively obtain the delamination condition of the rock layer 4 through the display screen 320.

[0055] It should be noted that the display screen 320 may generally include a data processor disposed inside the display screen 320, so that the signal transmitted by the data acquisition line 310 can be converted into image information through the data output device, so that the operator can intuitively obtain the delamination condition of the rock layer 4.

Finally, the seat body 110 is plugged into the opening of the rock formation hole 410, and the installation is completed. When testing, the seat body 110 located at position I transmits a signal to the roof separation instrument 1 located at position II. To detect the distance between the seat 110 and the roof separation meter 1 at position II, the roof separation meter 1 at position II can transmit a signal to the roof separation meter 1 at position III to detect the distance between the roof separation meter 1 at position II and the roof separation meter 1 at position III. The roof separation meter 1 at position III can transmit a signal to the roof separation meter 1 at position IV to detect the distance between the roof separation meter 1 at position III and the roof separation meter 1 at position IV. If any rock layer 4 at positions II, III, and IV becomes loose and collapses, the roof separation meters 1 at positions II, III, and IV will move, and the relative distance between each roof separation meter 1 will change. The operator can confirm the delamination condition of the rock layer 4 based on the image data information fed back by the display screen 320 to determine whether it is safe.
