Problems solved by technology

[0002] The water in the cable trench of the substation is damp, which will cause problems such as cable damp, cable frame rust and cable trench collapse for a long time
Seriously affect the service life of cables and cable trenches
The problem of cable trench dehumidification has always troubled various power supply companies. At present, all companies adopt the method of installing vents and opening the cable trench cover to dry in the sun to reduce the problem of cable trench moisture. This method, due to the lack of air circulation inside the cable trench, can only The cable trench about one meter on both sides of the cable cover plate can dehumidify, but it cannot dehumidify the cable trench as a whole, and the efficiency is low
[0003] A fire broke out in the cable trench of the substation. At present, there is no suitable fire fighting method. It can only be isolated by the firewall in the cable trench. If there is a gap in the firewall, it will cause the entire substation to catch fire.
Cause large-scale power outages, causing great losses to companies and users

Abstract

The invention provides an unpowered cable trench dehumidification and fire extinguishing device, and relates to the technical field of power protection devices. The unpowered cable trench dehumidification and fire extinguishing device is structurally characterized in that a photovoltaic panel and a raindrop sensor are arranged at the top end of a hollow shaft, wherein a hood is arranged in the middle of the hollow shaft through a bearing; the lower part of the hollow shaft is sequentially connected with a hood framework and a supporting framework; the hood framework is connected with a hood cylinder; the supporting framework is connected with a supporting cylinder; a rechargeable battery and an electromagnetic lock are arranged on the supporting framework; the raindrop sensor is in controlconnection with the electromagnetic lock; and when the electromagnetic lock is locked, a spring bolt can block the hood framework and the hood from rotating. The unpowered cable trench dehumidification and fire extinguishing device has the beneficial effects that mounting is easy, checking is convenient, air exchange dehumidification in a cable trench can be achieved on sunny days, humid air is prevented from entering the cable trench on rainy days, the cable trench can be illuminated, and when a fire disaster happens to the cable trench, the fire on the fire part can be automatically extinguished.
