AI Technical Summary

⚠Technical Problem

Existing cable duct fire extinguishing equipment lacks effective fire spread prevention mechanisms and instant alarm components, and the cable limiting effect is limited, leading to difficulties in fire spread and location.

⚗Method used

An automatic fireproof and fire-extinguishing cable trough device for electric shovel excavators was designed, comprising a limit component, a triggering mechanism, an alarm mechanism, and a sand-spraying mechanism. Through the coordinated work of fire sprinklers, linkage components, sound-emitting components, and sand storage components, it can achieve fire containment, alarm, and sand coverage to prevent the fire from spreading.

🎯Benefits of technology

It effectively seals off the fire, improves the cable restraint effect, promptly alerts the location of the fire source, prevents the fire from spreading, enhances the ventilation and sealing of the cable placement environment, and ensures the smooth progress of firefighting work.

Abstract

The application discloses an automatic fireproof and fire-extinguishing cable groove device of an electric shovel excavator, which comprises a containing mechanism, a limiting assembly, a top cover arranged on the limiting assembly, a fire-fighting nozzle arranged on the top cover, a triggering mechanism, a triggering assembly arranged on the top cover, a linkage assembly arranged on the top cover, a closing assembly arranged on the linkage assembly, a clockwork spring arranged on the closing assembly, and a heat dissipation groove arranged on the top cover. The heat dissipation groove increases the ventilation effect of the shell, improves the placing environment of the cable, avoids the cable from catching fire due to overheating, and the alarm sound emitted by the buzzer is convenient for workers to locate the fire point. The heat dissipation groove increases the ventilation effect of the shell, improves the placing environment of the cable, avoids the cable from catching fire due to overheating, the sealing ring and the top plate improve the sealing property between the closing door and the shell, and the fire is better blocked.
