Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 2This utility model provides a technical solution for a high-power electric heating and insulation device for mines: A high-power electric heating and insulation device for mines includes a base 1, an insulation box 4, and a control panel 20. Four support wheels 7 are installed in a rectangular array at the four corners of the bottom of the base 1. Two push-pull handles 18 are symmetrically installed at the rightmost end of the upper surface of the base 1. An insulation box 4 is installed at the left end of the upper surface of the base 1. Two heating cylinders 5 are symmetrically installed inside the insulation box 4. The two heating cylinders 5 are interconnected by a connecting pipe 10. Each heating cylinder 5 has an electric heating wire 8 installed at its bottom and a disc-shaped air duct 9 installed inside. In use, the electric heating wire 8 inside the two heating cylinders 5 is first energized through the control panel 20. The energized electric heating wire 8 heats the water inside the two heating cylinders 5. If the water temperature is too high, the pressure can be automatically released through the pressure relief valve 12.

[0018] The two disc-shaped air ducts 9 are connected by a connector 6. A fan 11 is embedded in the upper part of the left side plate of the insulation box 4. The air outlet of the fan 11 is connected to the left disc-shaped air duct 9. A nozzle 14 is installed at the air outlet of the right disc-shaped air duct 9. The nozzle 14 is installed on the top of the insulation box 4. The fan 11 is started through the control panel 20. The fan 11 first sends cold air into the left disc-shaped air duct 9 for heating, then into the right disc-shaped air duct 9 for further heating, and finally blows it out from the nozzle 14 to raise the temperature inside the mine.

[0019] Both heating cylinders 5 are equipped with pressure relief valves 12 on their tops. The left heating cylinder 5 has a liquid level sensor 13 on its top. A water tank 2 is installed at the rear end of the upper surface of the base 1. The water tank 2 has a filling port 17 in the middle of its top and a water pump 16 installed at its left end. The water pump 16's inlet is connected to the water tank 2 via water pipe 1 3, and its outlet is connected to the right heating cylinder 5 via water pipe 2 15. During operation, when the liquid level sensor 13 detects that the water level in the heating cylinder 5 is low, it will transmit a signal to the control panel 20. The control panel 20 will then start the water pump 16. The water pump 16 will draw water from the water tank 2 through water pipe 1 3 and send it to the heating cylinder 5 through water pipe 2 15 to replenish the water. The insulation box 4 has two doors 19 mounted on its front hinge. The control panel 20 is embedded in the upper right corner of the insulation box 4. The control panel 20 is electrically connected to the heating wire 8, the fan 11, and the water pump 16.

[0020] When this utility model is in use, firstly, the heating wires 8 inside the two heating cylinders 5 are energized through the control panel 20. The energized heating wires 8 heat the water inside the two heating cylinders 5. If the water temperature is too high, the pressure can be automatically released through the pressure relief valve 12. Then, the fan 11 is started through the control panel 20. The fan 11 first sends cold air into the left disc-shaped air duct 9 for heating, then into the right disc-shaped air duct 9 for further heating, and finally blows it out from the air nozzle 14 to raise the temperature inside the mine. During the operation, when the liquid level sensor 13 detects that the water level in the heating cylinder 5 is low, it will transmit a signal to the control panel 20. The control panel 20 starts the water pump 16. The water pump 16 works to draw water out of the water tank 2 through the water pipe 1 3 and send it to the heating cylinder 5 through the water pipe 2 15 to replenish the water.
