[0026] Specifically, when the redundant part of cable 2 needs to be stored, first, open cable storage shell 5, then wind the redundant part of cable 2 outside hollow outer cylinder 42, and place it inside multiple elastic cable clamp plates 6. Under the elastic action of multiple elastic cable clamp plates 6, the redundant part of cable 2 is effectively stored. After winding the redundant part of cable 2, place the part of cable 2 that needs to be extended out of cable storage shell 5 on cable limiting plate 7. Finally, buckle cable storage shell 5 on cable storage bottom plate 4.

[0027] Specifically, when the mine intrinsic safety type temperature sensor is used for temperature monitoring, temperature probe 3 can monitor the temperature data in mine or mining area in real time, and transmit these data to temperature transmitting module through cable 2. After receiving the data, temperature transmitting module will process and convert the signal, and transmit the temperature information to upper control system or alarm device. The circuit structure involved here is prior art, and will not be described here.

[0028] Further, the left side of the upper surface of cable storage bottom plate 4 is fixedly connected with two groups of fixed pin seats one 41, the left side of the lower surface of the top wall of cable storage shell 5 is fixedly connected with two groups of fixed pin seats two 51, the two groups of fixed pin seats one 41 and the two groups of fixed pin seats two 51 are one-to-one corresponding, and the fixed pin seat one 41 and the corresponding fixed pin seat two 51 are fixed by fixed screws 52.

[0029] Specifically, detachable structure is adopted between cable storage bottom plate 4 and cable storage shell 5, which is convenient for subsequent staff to disassemble and assemble cable storage shell 5.

[0041] Specifically, when it is necessary to fix the outer shell 1 and the mounting surface, the mounting base plate 8 can be fixed to the lower surface of the outer shell 1 by screws. The mounting base plate 8 in the shape of a Chinese character leaves a certain ventilation gap between the outer shell 1 and the mounting surface.

[0042] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection scope of the present application.
