[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] like Figure 1 and Figure 2 As shown, a temperature control, cooling and fire extinguishing device for a coal gangue mountain comprises a temperature control insert 1 buried inside the gangue mountain, an insulating sleeve 2 is arranged on the temperature control insert 1, the bottom of the temperature control insert 1 is closed, a heat dissipation pipe section 3 is installed on the top through a flange, a heat exchange medium is filled inside the temperature control insert 1, the top of the heat dissipation pipe section 3 is closed and a vacuum control valve 4 is installed on the top; the heat dissipation pipe section 3 comprises a connecting pipe 5 and a heat exchange sleeve 6 installed outside the connecting pipe, the bottom of the connecting pipe 5 is connected to the temperature control insert 1 through a flange, the vacuum control valve 4 is arranged on the top of the heat exchange sleeve 6, and a plurality of movable heat dissipation fins 7 are installed on the outside of the heat exchange sleeve 6.

[0015] The utility model adopts a heat dissipation pipe section 3 that can be freely disassembled and installed on the temperature control plug 1. The heat dissipation pipe section 3 can be produced separately in different models according to actual needs. The heat dissipation pipe section 3 also includes a connecting pipe 5, a heat exchange sleeve 6 and a heat dissipation fin 7. The connecting pipe 5 is used to connect with the temperature control plug 1, and the heat exchange sleeve 6 is installed on the outside of the connecting pipe 5 and is used to be installed on the heat dissipation fin 7. The heat exchange sleeve 6 is sleeved on the outside of the connecting pipe 5, mainly for the convenience of later maintenance. Due to long-term use, the heat exchange sleeve 6 may be damaged, and the maintenance cost can be reduced by the heat exchange sleeve 6. The heat dissipation fin 7 is movably installed on the heat exchange sleeve 6, and the number and spacing of the heat dissipation fins can be adjusted as needed to achieve dynamic adjustment of the heat dissipation power. The outer wall of the connecting pipe 5 is provided with a plurality of positioning protrusions 11, and correspondingly, the inner wall of the heat exchange sleeve 6 is provided with a plurality of positioning card slots 12, and the positioning protrusions 11 are installed in the positioning card slots 12. The installation and positioning of the heat exchange sleeve 6 and the connecting pipe 5 are more convenient. The bottom of the temperature control tube is a conical structure 16, which is small at the top and large at the bottom. The conical structure 16 can increase the heat absorption area and adapt to different gangue temperature scenes. The vacuum control valve 4 is reserved for backup to prevent the generation of bad gas inside the tube wall. If the device cannot be taken out of the site, the bad gas can be discharged through the vacuum control valve to restore the function of the cooling device.

[0016] The heat exchange medium in the heat absorption section at the bottom of the temperature control insert 1 absorbs heat and becomes gasified, rising to the upper end of the tube body, and dissipates the temperature into the atmosphere through the heat dissipation fins 7, thereby achieving the purpose of lowering the underground temperature of the waste rock mountain. When the gasified part dissipates heat and forms a liquefied state again, the heat exchange medium flows back to the heat absorption section, and the cycle is repeated to complete the entire process of heat dissipation and cooling. The heat insulation sleeve 2 uses heat insulation materials to separate the temperature of the tube body from the ground, so that the temperature of the tube body will not affect the ground temperature of the planting land, and the ground vegetation can grow well.

[0017] Among them, a plurality of T-shaped fixed slots 8 are evenly arranged on the outer circumference of the heat exchange sleeve 6, and the T-shaped fixed slots 8 are arranged along the length direction of the heat exchange sleeve 6. A fixed card plate 9 is installed on one side of the heat exchange fin 7, and the fixed card plate 9 is installed in the T-shaped fixed slot 8. With this structure, the heat exchange fin 7 is easy to install and disassemble, and easy to adjust. Three annular notches 10 are also arranged on the circumference of the heat exchange sleeve 6, and the three annular notches 10 divide the plurality of T-shaped fixed slots into four sections along the length direction of the heat exchange sleeve 6. In this way, when arranging the heat exchange fins 7, they can be arranged in sections, and the spacing adjustment is also more flexible. At the same time, the annular notches 10 can increase the diversion and heat dissipation effect of the heat exchange fins 7, and improve the heat dissipation efficiency by increasing the flow of cold air.

[0018] A plurality of guide grooves 13 are correspondingly arranged on the inner walls of the connecting pipe 5 and the temperature control insert 1. The guide grooves 13 are arranged along the length direction. A conical guide plate 14 is installed on the inner wall of the connecting pipe 5. A guide port 15 connected to the guide groove is arranged on the conical guide plate 14. The conical guide plate 14 can collect the liquefied heat exchange medium so that the heat exchange medium can flow back to the bottom of the temperature control insert 1 along the guide groove 13.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the scope of the present invention.
