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.

[0024] like Figures 1 to 4 As shown, a goaf spontaneous combustion prevention device protection box in one embodiment of the utility model includes a protection box body 11, and a prevention device body 21 is arranged inside the protection box body 11. A protection door 12 is hinged on the protection box body 11, and a plurality of casters 13 are arranged at the bottom of the protection box body 11. A push rod 14 is fixedly connected to the protection box body 11, and a gas delivery port 25 is arranged on the prevention device body 21, and a gas delivery pipe 61 is fixedly connected to the gas delivery port 25, and the gas delivery pipe 61 extends to the outside of the protection box body 11.

[0025] Specifically, the protection box body 11 can provide protection for the prevention device body 21. The push rod 14 and the casters 13 provided at the bottom of the protection box body 11 facilitate the movement of the protection box body 11 and the prevention device body 21 located inside the protection box body 11. The gas pipe 61 facilitates the injection of nitrogen into the goaf to reduce the oxygen content in the goaf, thereby achieving the purpose of extinguishing or preventing fire. The prevention device body 21 can be operated by opening the protection door 12.

[0026] A fixing block 16 is fixedly connected inside the protection box body 11, and a fixing frame 22 matching the fixing block 16 is fixedly connected to the bottom of the prevention and control device body 21. There are two fixing blocks 16, and the gas pipe 61 is fixedly connected to the bottom wall inside the protection box body 11. The fixing frame 22 can be snapped onto the fixing block 16 to ensure the stability of the prevention and control device body 21 in the protection box body 11. At the same time, the fixing frame 22 can slide on the fixing block 16, which is convenient for taking the prevention and control device body 21 out of the protection box body 11 or installing the prevention and control device body 21 into the protection box body 11.

[0027] A third fixing hole 26 is formed in the fixing frame 22, a first fixing hole 17 matching the third fixing hole 26 is formed in the fixing block 16, and a fixing bolt 31 is threadedly connected between the first fixing hole 17 and the third fixing hole 26 to increase the stability of the main body 21 of the prevention and control device.

[0028] The protection box body 11 is provided with a threaded hole 42, a threaded rod 41 is threadedly connected to the threaded hole 42, and a handle 43 is fixedly connected to the threaded rod 41. The handle 43 facilitates the rotation of the threaded rod 41, and the threaded rod 41 can abut against the side of the prevention and control device body 21, further increasing the stability of the prevention and control device body 21 in the protection box body 11.

[0029] A support plate 51 is provided between the threaded rod 41 and the prevention and control device body 21. The threaded rod 41 can push the support plate 51, and the support plate 51 can increase the area of ​​the prevention and control device body 21.

[0030] A limiting block 24 matching the support plate 51 is fixedly connected to the main body 21 of the prevention and control device. The limiting block 24 can limit the support plate 51 to ensure the stability of the support plate 51.

A handle 23 is fixedly connected to the prevention and control device body 21.

[0032] Specifically, when it is necessary to remove the prevention and control device body 21 from the protection box body 11, the threaded rod 41 can be loosened so that the support plate 51 no longer abuts against the prevention and control device body 21. The protection door 12 is opened, and the support plate 51 is taken out from the limit block 24 so that the fourth fixing hole on the support block 52 is aligned with the second fixing hole 18. The bottom end surface of the support plate 51 is supported on the ground, and the upper end surface of the support plate 51 is flush with the upper end surface of the fixing block 16. Then the fixing bolt 31 is loosened, and the unscrewed fixing bolt 31 is threadedly connected between the second fixing hole 18 and the fourth fixing hole, so that the support plate 51 and the protection box body 11 are fixedly connected together.

[0033] By pulling the control device body 21 outwards through the handle 23, the fixing frame 22 at the bottom of the control device body 21 can move along the fixing block 16 and the support plate 51, so that the control device body 21 can be conveniently moved to the outside of the protection box body 11 for maintenance of the control device body 21. After the maintenance is completed, it is also convenient to move the control device body 21 back into the protection box body 11 and then fix the control device body 21.

[0034] A plurality of fixing plates 15 are fixedly connected to the protection box body 11. The gas pipe 61 can be stuck between the fixing plates 15, so that the gas pipe 61 can be stored easily.

[0035] The gas delivery pipe 61 is fixedly connected with a connecting sleeve 62 matching the gas delivery port 25. The gas delivery port 25 is provided with an external thread, and the connecting sleeve 62 is provided with an internal thread matching the external thread. The connecting sleeve 62 can be threadedly connected to the gas delivery port 25, which is convenient for installing and removing the gas delivery pipe 61.

[0036] When using, refer to Figure 1 to Figure 4 As shown, the prevention and control device body 21 is installed in the protection box body 11, and the protection box body 11 can protect the prevention and control device body 21. The casters 13 and the push rod 14 facilitate the movement of the protection box body 11 and the prevention and control device body 21 located in the protection box body 11.

[0037] Compared with the prior art, the utility model provides a protective box for a goaf spontaneous combustion prevention device, which can protect the prevention device, reduce the possibility of damage to the prevention device, and facilitate transportation.
