[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figures 1 to 4 As shown, a three-zone measuring device for a coal mine working face in one embodiment of the utility model includes a measuring probe 2, one end of which is fixedly installed with a high-definition camera module 6 and an LED light-emitting module 7. Through the cooperation of the high-definition camera module 6 and the LED light-emitting module 7, photos can be obtained to provide the rock type of the borehole wall and the degree of coal rock layer fragmentation.

[0028] The other end of the measuring probe 2 is fixedly connected with a transmission cable 3, which is used for power supply and signal transmission during the operation of components such as the high-definition camera module 6 and the LED light-emitting module 7.

[0029] The measuring probe 2 is slidably inserted into the outer cylinder 1, and the outer cylinder 1 can fully protect the measuring probe 2, so that the components on the measuring probe 2 are not easily damaged. Multiple sets of support wheels 5 are installed on the end of the measuring probe 2 close to the high-definition camera module 6, and the multiple sets of support wheels 5 are in contact with the inner wall of the outer cylinder 1. The measuring probe 2 can be supported by the multiple sets of support wheels 5, so that the measuring probe 2 can move on the inner wall of the outer cylinder 1.

[0030] A driving assembly is installed on the measuring probe 2, and the driving assembly includes three sets of motor drive wheels 4. The motor drive wheels 4 are common knowledge to those skilled in the art and will not be described in detail here. The three sets of motor drive wheels 4 are installed in a circular distribution on the end of the measuring probe 2 away from the high-definition camera module 6. The three sets of motor drive wheels 4 are all driven by independent motors, so that the three sets of motor drive wheels 4 can automatically walk on the inner wall of the outer cylinder 1, thereby driving the measuring probe 2 to move inside the outer cylinder 1.

[0031] Specifically, the front end of the measuring probe 2 is supported by multiple sets of supporting wheels 5, and moves on the inner wall of the outer cylinder 1 through three sets of motor-driven wheels 4, so as to push the measuring probe 2 to move smoothly inside the outer cylinder 1 from the rear.

[0032] A pair of protective end covers 8 are rotatably connected to one end of the outer cylinder 1 close to the high-definition camera module 6, wherein a support block 802 is fixedly connected to the pair of protective end covers 8, and a pair of connecting grooves 102 matching the pair of supporting blocks 802 are opened at one end of the outer cylinder 1, and the pair of supporting blocks 802 are rotatably connected to the inside of the pair of connecting grooves 102 respectively, and the protective end covers 8 are rotatably connected to the outer cylinder 1 through the support blocks 802.

[0033] A pair of protective end caps 8 are used to protect the high-definition camera module 6 and the LED light module 7. A linkage assembly is installed between the measuring probe 2 and the pair of protective end caps 8, and the linkage assembly includes a pair of connecting rods 9, which are respectively movably hinged between the pair of protective end caps 8 and the measuring probe 2.

[0034] Specifically, the pair of protective end covers 8 are fixedly connected with extension pieces 801, one end of the pair of connecting rods 9 is rotatably connected to the extension pieces 801 on the pair of protective end covers 8, and the other end of the pair of connecting rods 9 is rotatably connected to the measuring probe 2. When the measuring probe 2 moves inside the outer cylinder 1, the protective end covers 8 can be pushed and pulled by the connecting rods 9 to rotate, so that the protective end covers 8 can automatically rotate and open.

[0035] like Figure 3 and Figure 4 As shown, in the process of pushing the probe rod into the borehole, a pair of protective end covers 8 are in a closed state, which can well protect the high-definition camera module 6 and the LED light module 7. When the high-definition camera module 6 and the LED light module 7 need to obtain photos of the inside of the borehole, the measuring probe rod 2 is moved forward inside the outer cylinder 1, and the measuring probe rod 2 can push the protective end cover 8 to open through the connecting rod 9, so that the high-definition camera module 6 and the LED light module 7 are exposed to obtain clear photos of the inside of the borehole. In the subsequent pushing process, the pair of protective end covers 8 are closed again to protect the high-definition camera module 6 and the LED light module 7. This can effectively ensure that the high-definition camera module 6 and the LED light module 7 will not be damaged by pollution, etc., and ensure normal use.

[0036] Among them, the protective end cover 8 is a transparent acrylic protective end cover. If the surface of the protective end cover 8 is not contaminated, there is no need to open the protective end cover 8. The high-definition camera module 6 and the LED light-emitting module 7 can also obtain photos, which is more convenient to use.

[0037] The outer cylinder 1 is provided with a plurality of through holes 101, which are inclined toward the side close to the protective end cover 8, and the inclination angle is 45°. The through holes 101 can provide a passage for the work of other components on the measuring probe 2, and the through holes 101 are inclined. During the pushing process of the probe, impurities are not easy to enter the through holes 101, thus preventing the through holes 101 from being blocked.

[0038] When in use, the outer cylinder 1 is pushed into the borehole. When taking pictures is needed, the motor driving wheel 4 is used to drive the measuring probe 2 to move forward inside the outer cylinder 1. The measuring probe 2 will push the protective end cover 8 to rotate and open through the connecting rod 9. At this time, the high-definition camera module 6 and the LED light-emitting module 7 are both exposed. After taking the picture, the measuring probe 2 retreats and pulls the protective end cover 8 to close. Then the outer cylinder 1 can continue to advance into the borehole until the measurement of the "three-zone" height of the roof overburden of the coal mining working face is completed.

[0039] The utility model can provide overall protection for the measuring probe 2 through the outer cylinder 1, and can protect the high-definition camera module 6 and the LED light-emitting module 7 without affecting their normal operation through a pair of protective end covers 8 that can be flexibly opened and closed, so that the high-definition camera module 6 and the LED light-emitting module 7 are not easily contaminated, ensuring that all components on the measuring probe 2 can function normally inside the borehole, thereby accurately completing the "three-band" height measurement work.
