[0029] Working principle: Since the above patent provides a cooling device for coal mine electromechanical equipment, although it can save water and reduce the waste of water resources, the heat exchange through heat exchange will turn the original hot air into cold air, and the cold air will gradually dissipate in the heat dissipation box, so that the corresponding cold air utilization rate is not high, and the adaptability of the work needs to be improved. When working, the mobile base 1 supports the heat exchange box 2, and the heat exchange box 2 performs heat exchange and cooling, and the hot air after heat exchange will become cold air. The cold air is introduced into the L-shaped duct 5 through the cold air hose 3, which is convenient for the trapezoidal jet nozzle 6 to spray the cold air. In addition, in order to increase the spray range of the cold air, a reciprocating The rotation of the screw rod 8 drives the sliding block 9 to slide back and forth, and the sliding block 9 has fixed teeth on its surface, and the teeth on the surface of the sliding block 9 cooperate with the transmission gear 4 to drive the transmission gear 4 to rotate. Since the sliding block 9 is in a reciprocating state, the transmission gear 4 rotates back and forth, thereby driving the L-shaped duct 5 to rotate back and forth, so that the trapezoidal jet nozzle 6 swings back and forth, expanding the range of cold air spraying, making full use of the cold air after heat exchange, and improving the cooling effect.

The heat near the coal mine electromechanical equipment is absorbed in the form of hot air for heat exchange inside the heat exchange box 2, and the cold air after heat exchange is transported to the L-shaped duct 5 through the cold air hose 3, and then the trapezoidal jet nozzle 6 sprays the cold air out. In this process, the reciprocating screw 8 can drive the sliding block 9 to slide back and forth, and then cooperate with the teeth to continuously mesh with the transmission gear 4 for transmission. The transmission gear 4 drives the L-shaped duct 5 to rotate back and forth, and then drives the trapezoidal jet nozzle 6 to swing, thereby expanding the range of cold air spraying, making full use of the cold air after heat exchange, and improving the cooling effect.
