[0028] The beneficial effects of the present invention are:

[0029] 1. This cooling device for coal mine electromechanical equipment is provided with a cooling mechanism. When the serpentine tube is connected to the refrigerator, the refrigerant will vaporize and absorb heat when passing through the serpentine tube, thereby reducing the temperature of the air around the serpentine tube. When the blower is working, it will continuously blow air in. After the air is cooled by the serpentine tube, it will pass through the second installation box. When the cooling fan rotates, it will draw the air behind the fan blades to the front of the fan blades. Under the action of the blower and the cooling fan, the cold air will quickly enter the cooling chamber, reducing the temperature in the cooling chamber. At the same time, the blower and the cooling fan can also accelerate the air circulation in the cooling chamber. Therefore, under the dual action of cold air and wind force, the cooling effect of the equipment can be improved.

[0030] 2. This cooling device for coal mine electromechanical equipment, due to the transmission relationship between the sprocket and the chain, and the meshing relationship between the two second bevel gears, can simultaneously drive the corresponding two bidirectional screws to rotate when the second micro motor is working. Under the threaded connection relationship between the bidirectional screw and the first screw barrel, the support rod will support the mounting plate, thereby changing the distance between the mounting plate and the second mounting box, making it convenient for the cooling fan on the mounting plate to approach the electromechanical equipment that needs to be cooled, so that the low-temperature airflow is directly blown onto the electromechanical equipment, thereby improving the cooling effect.

[0031] 3. This cooling device for electromechanical equipment in coal mines injects a sufficient amount of coolant into the liquid storage tank by setting a pretreatment mechanism and a transmission mechanism, and then connects the air guide pipe on the air pump to the interface of the arc-shaped air pipe and the air filling port of the liquid storage tank. When the air pump sends air into the arc-shaped air pipe, the air will be pressurized and ejected through the pressurized nozzle on the arc-shaped air pipe, which can blow away the dust on the electromechanical equipment. When the air pump inflates the liquid storage tank, under the action of air pressure, the coolant in the liquid storage tank will be transported to the spray head along the guide pipe, and will be atomized and ejected after passing through the spray head. At the same time, under the meshing action of the bevel gear ring and the third bevel gear, the third micro motor will drive the spray head to rotate after starting, so that the atomized coolant is evenly sprayed on the electromechanical equipment, which can disinfect and cool the surface of the electromechanical equipment.

[0032] 4. This cooling device for coal mine electromechanical equipment, due to the meshing relationship between the second gear and the two first gears, can drive the two screws to rotate at the same time when the first motor is started. Under the threaded connection relationship between the two second screw barrels and the two screws, the position of the support plate will change with the rotation of the two screws, thereby carrying the electromechanical equipment through the arc air pipe and the sprinkler head in sequence, thereby achieving dust removal, disinfection and cooling of the electromechanical equipment.

[0033] 5. This cooling device for coal mine electromechanical equipment has sliders at the four corners of the lower surface of the support plate, and the shape of each slider matches the shape of the slide rails on both sides, and each slider is provided with a number of balls. At the same time, rotating rollers are provided on both sides of the bottom plate of the support plate. Therefore, under the rolling action of the balls and rollers, the sliding smoothness of the support plate can be improved, preventing the support plate from getting stuck when moving.

[0034] 6. This cooling device is used for electromechanical equipment in coal mines. When the electromechanical equipment enters the cooling chamber, the first micromotor will drive the rotating rod to rotate through the meshing relationship of the two first bevel gears, thereby lowering the insulation cloth. When the iron sheet under the insulation cloth is attracted to the magnetic block on the bottom plate of the clean room, the insulation cloth will separate the cooling chamber from the clean room, maintaining the low temperature environment in the cooling chamber.

When the blower 6 is working, it will continuously blow air into the first installation box 3. After the air is cooled by the serpentine tube 5, it will be sent to the rear of the cooling fan 8. When the cooling fan 8 rotates, the air behind the fan blades will be drawn to the front of the fan blades. Under the action of the blower 6 and the cooling fan 8, the cold air will quickly enter the cooling room 1, reducing the temperature in the cooling room 1. At the same time, The blower 6 and the cooling fan 8 can also accelerate the air circulation in the cooling room 1, thereby improving the cooling effect of the equipment under the dual effects of cold air and wind. If the cooling fans 8 on both sides are far away from the electromechanical equipment, the positions of the cooling fans 8 on both sides can be adjusted. By utilizing the transmission relationship between the sprocket 12 and the chain 13, and the meshing relationship between the two second bevel gears 36, the second micro motor 35 can simultaneously drive the corresponding two bidirectional screws 9 to rotate when working. Under the threaded connection relationship between the bidirectional screw 9 and the first screw barrel 10, the support rod 11 will support the mounting plate 7, thereby changing the distance between the mounting plate 7 and the second mounting box 4, making it convenient for the cooling fan 8 on the mounting plate 7 to be close to the electromechanical equipment that needs to be cooled, so that the low-temperature airflow is directly blown onto the electromechanical equipment.Improve the cooling effect.
