Description

Technical Field

[0001] The utility model belongs to the technical field of mine equipment, and in particular relates to a cooling air duct cleaning mechanism for an underground charger. Background Art

[0002] The heat dissipation duct design of the underground charger is the key to ensuring the normal operation of the charger in harsh underground environments such as high temperature, humidity, and dust. The heat dissipation duct can discharge the high-temperature gases generated when the underground charger is working to the outside world through the heat dissipation duct, thereby preventing heat, dust, etc. from spreading underground and affecting the use of mechanical equipment.

[0003] When cleaning the cooling air duct of the existing underground charger, usually only the filter is cleaned. However, it is relatively humid and dusty underground, and a large amount of dust and impurities will adhere to the inner wall of the cooling air duct when it is in use. The dust and impurities will adhere to the inner wall of the cooling air duct and corrode the cooling air duct, affecting the service life of the cooling air duct. Moreover, more dust accumulation will make the air outlet of the cooling air duct smaller, thereby affecting the heat dissipation efficiency. For this reason, we propose a cooling air duct cleaning mechanism for an underground charger. Utility Model Content

[0020] The working principle and use process of the utility model: when the heat dissipation duct 1 is cooling the underground charger, because there are many dust and impurities in the underground, a large amount of dust and impurities will be attached to the inner wall of the heat dissipation duct 1 after a period of use.

At this time, the rope is slowly unwound, and the shell 2 moves vertically downward by its own weight, and the motor 4 and the air pump 11 are started at the same time. The motor 4 drives the rotating shaft 5 and the rotating gear 6 to rotate, and the rotating gear 6 rotates to drive the driven gear 7 and the U-shaped The rotating plate 8 rotates, and the rotation of the U-shaped rotating plate 8 drives the scraping block 9 and the brush 10 to rotate.
