Substation smart cable manhole cover with fire alarm

Abstract

The invention relates to a transformer substation intelligent cable well lid with a fire alarm function. The defects in the prior art are overcome. According to the technical scheme, the transformer substation intelligent cable well lid is characterized in that a hydraulic cylinder is fixedly arranged on a fixed block; the hydraulic cylinder is used for controlling the hydraulic rod to stretch outand draw back; the first end of the hydraulic rod is connected with the hydraulic cylinder; the second end of the hydraulic rod abuts against the bottom of a lock hook; a connecting base is further arranged between the hydraulic device and the well lid; a locking piece is arranged on a connecting base in the horizontal direction, and the locking piece is arranged between the well lid and a limiting part; the starting control end of the hydraulic device is connected with an electric control device; one signal input end of the electric control device is communicated with the lock cylinder; thehydraulic device is powered by a driving power supply; the driving power supply is fixed on the side wall of a cable well; the electric control device is installed on the fixed block; a fire alarm isinstalled on the back face of the well lid body; the fire alarm is connected with the input end of the electric control device; and the fire alarm is powered by a weak current power supply.

Description

technical field [0001] The invention relates to a cable well cover, in particular to a substation intelligent cable well cover with fire alarm. Background technique [0002] Although the smart grid has been promoted for a long time, there is no IoT-style product that matches it in the substation cable trench. The internal conditions of the conventional cable trenches all depend on the daily maintenance of the operation and maintenance personnel, and the internal conditions of the cable trenches can only be known by opening the cover. There is no way to predict and solve many unexpected situations. Therefore, it is necessary to design a monitoring system that can monitor the internal conditions of the cable trench in an all-round way and eliminate potential safety hazards before they happen. At the same time, in the conventional power maintenance process, the opening of the manhole cover needs to be opened by relevant personnel on site, and the remote control lifting functi...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the above-mentioned prior art that only the structure of the manhole cover itself is detected, but the environment where the manhole cover and its nearby cables are not detected, and the manhole cover cannot realize the function of automatic lifting, which has a single function and is inconvenient to use. problem, providing a substation smart cable manhole cover with fire alarm
