In this arrangement, a transmission assembly is arranged between the pressure plate and the detection body, and the linkage between the two is realized through a mechanical transmission structure. If falling rocks fall on the pressure plate, the pressure plate moves downward, and the transmission assembly is driven to drive the detection body to move into the protective shell, thereby effectively resisting the impact of falling rocks, ensuring the safe and reliable operation of the detection device, and enabling the detection assembly to continue to be used when a small-scale collapse occurs in the mine.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following is a brief description of the present invention in conjunction with the attached drawings. Figure 1 —8 A detailed description is given of the specific embodiments of the present invention.

[0041] In the present invention, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure.

[0042] In the present invention, terms such as "inside", "outside", "upper" and "lower" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] The embodiment of the present invention provides a coal mine environment detection device, see the attached Figure 1 The coal mine environment detection device includes a base plate 1, a protective component 2 and a detection component 27. The protective component 2 includes a protective shell 21 and a pressure plate 22. The protective shell 21 is fixed to the base plate 1 and has an opening at one end; the pressure plate 22 is connected to the protective shell 21 or the base plate 1; the detection component 27 can be movably connected to the base plate 1; the protective component 2 and the detection component 27 are configured as follows: if the pressure plate 22 is not subjected to external pressure, the detection component 27 is located below the pressure plate 22 and on the outside of the protective shell 21; if the pressure plate 22 is subjected to external pressure, the detection component 27 moves to the inside of the protective shell 21 through the opening. With such arrangement, on the one hand, the detection component 27 is arranged below the pressure plate 22, which can prevent falling rocks from hitting the detection component 27; on the other hand, the pressure plate 22 bears the pressure of falling rocks, and the detection component 27 enters the protective shell 21 through the opening, which can effectively resist the impact of falling rocks and ensure the safe and reliable operation of the detection device, so that the detection component 27 can continue to be used when a small-scale collapse occurs in the mine.

[0044] See attached Figure 2In the embodiment of the present invention, the detection assembly 27 includes a detection body 271 and a detection module. The detection body 271 is movably connected to the bottom plate 1, and the detection module is arranged on the detection body 271. A transmission assembly is arranged between the detection body 271 and the pressure plate 22, and the transmission assembly is configured as follows: if the pressure plate 22 is subjected to external pressure, the pressure plate 22 moves downward relative to the protective shell 21, and the driving transmission assembly drives the detection body 271 to move to the inner side of the protective shell 21. In this way, a transmission assembly is arranged between the pressure plate 22 and the detection body 271, and the linkage between the two is realized through a mechanical transmission structure. If a rock falls on the pressure plate 22, the pressure plate 22 moves downward, and the driving transmission assembly drives the detection body 271 to move into the protective shell 21, thereby effectively resisting the impact of the rock fall, ensuring the safe and reliable operation of the detection device, and enabling the detection assembly 27 to continue to be used when a small-scale collapse occurs in the mine.

[0045] See attached Figure 2 In the embodiment of the present invention, the transmission assembly includes a first screw 25, a first rack 23 and a first gear 24. The first screw 25 is perpendicular to the plane where the opening is located. One end of the first screw 25 is threadedly connected to the detection body 271, and the other end is pivoted to the protective shell 21. The first gear 24 is installed on the first screw 25 and meshes with one end of the first rack 23. The other end of the first rack 23 passes through the protective shell 21 and is connected to the bottom of the pressure plate 22. Working principle: If the falling rock falls on the pressure plate 22, the pressure plate 22 moves downward, and the first rack 23 connected to the pressure plate 22 drives the first gear 24 to rotate, and the first screw 25 connected to the first gear 24 rotates, driving the detection body 271 threadedly connected to the first screw 25 to move and enter the protective shell 21 through the opening. In this way, the present invention arranges a first screw 25, a first gear 24 and a first rack 23 between the detection body 271 and the pressure plate 22. When falling rocks hit the pressure plate 22, the detection body 271 and the pressure plate 22 are linked. The detection body 271 drives the detection module to quickly extend into the protective shell 21, avoiding direct damage to the detection module by falling rocks, ensuring the safe and reliable operation of the detection module, and allowing the detection module to continue to be used when a small-scale collapse occurs in the mine.

[0046] It should be noted that the structure of the transmission assembly is not limited and may also be other structures, such as a cam-connecting rod mechanism, which will not be described in detail here.

In this way, the spring support rod 210 is arranged between the pressure plate 22 and the bottom plate 1. On the one hand, when falling rocks fall on the pressure plate 22, the weight of the falling rocks drives the pressure plate 22 to drive the first rack 23 to move downward, and the spring support rod 210 is compressed to store elastic potential energy, thereby reducing the impact of falling rocks; on the other hand, when there are no falling rocks on the pressure plate 22, the elastic potential energy stored in the spring support rod 210 is released, so that the pressure plate 22 is reset.

[0049] See attached Figure 3 In this embodiment of the present invention, the pressure plate 22 includes a first pressure plate 221 and a second pressure plate 224.

In this way, when the first pressure plate 221 moves to the top of the protective shell 21, the falling rocks falling on the second pressure plate 224 drive the second pressure plate 224 to rotate downward relative to the first pressure plate 221, so that the second pressure plate 224 blocks the opening of the protective shell 21, reducing the falling rocks from entering the protective shell 21 and affecting the operation of the detection module.
