The explosion-proof cable is a cable with explosion-proof characteristics, and its insulation layer and sheath material usually have good flame retardant, temperature resistance, and aging resistance properties, which can be safely used in flammable and explosive environments. The explosion-proof cable winding positions 101 are wound around the outer circumference of the rotating winding reel 1.

[0027] Working principle

[0028] When using this explosion-proof cable reel, first wind the explosion-proof cable winding position 101 around the outer circumference of the rotating reel 1. Then turn on the fan 206. The fan 206 draws outside air from the filter canister 2 into the ventilation pipe 304. The incoming air is then ejected through the ventilation slot 306, which in turn blows the heat sink 302. Due to the inclined installation of the heat sink 302, it causes the circular slider 301 to rotate within the circular groove 3. The incoming air rotates in conjunction with the explosion-proof cable winding position 101 around the outer circumference of the rotating reel 1. Contact is achieved to realize heat exchange, reduce the temperature of the explosion-proof cable winding position 101, and achieve heat dissipation. When air enters the filter barrel 2, the air comes into contact with the filter plate 203 to filter the air and prevent impurities from entering. After a period of use, the throughput of the filter plate 203 decreases, and the air squeezes the filter plate 203 and the filter plate frame 204. The filter plate frame 204 squeezes the spring 205. By observing the position of the filter plate 203, it can be determined whether the filter plate 203 needs to be removed from the arc-shaped sealing plate 202 for replacement.
