Underground safety lamp for power cable working well

Abstract

The invention discloses an underground safety lamp for a power cable working well. The underground safety lamp comprises a shell, a lampshade connected with the shell, an installation plate, a support, a storage battery, an LED lamp set, a gas sensor set and a controller. The installation plate is fixedly installed between the shell and the lampshade, the support is connected with the shell, the storage battery is arranged in the shell, the LED lamp set and the gas sensor set are arranged on the installation plate, and the controller is electrically connected with the storage battery, the LED lamp set and the gas sensor set. According to the underground safety lamp, the structure is simple, the cost is low, carrying is convenient, operation is easy, performance is excellent, the service life is long, the maintenance cost is low, good illumination conditions can be provided for on-site operation environment, the integrated gas detection function can achieve 100% real-time automatic detection and warning in the whole operation process, the safety of the one-site operation environment is effectively improved, accidents are avoided, economic benefits are improved, early-stage preparation time of power cable underground operation is effectively shortened, user power-failure time is shortened, and the awareness that power enterprises serve the society is improved.

Description

technical field [0001] The invention relates to an underground safety lamp used in electric cable wells. Background technique [0002] Power cable lines are one of the main elements for the transmission and distribution of electrical energy in the grid. The use of cables for power transmission and distribution in urban roads and large factories is conducive to the neat and beautiful city appearance and factory appearance; cable power supply is relatively safe for people, and natural meteorological factors and surrounding environments have little influence on cables. [0003] Power cable wells are widely used in cable laying projects. Since each cable is only a certain length, about several hundred meters, in order to lay longer cable lines, it is necessary to connect multiple sections of cables, and making and placing cable joints requires a certain amount of time. Space, this space is called the power cable worker's well. [0004] Since the power cable well is a confined ...

AI Technical Summary

Problems solved by technology

To carry out gas detection work, operators must carry a gas detector with them, which increases the number of tools that operators need to carry and reduces the convenience of on-site construction

At the same time, due to the negligence of the operators, it often occurs that the wells go into the well without gas detection. In recent years, the casualties of the operators due to the lack of gas detection are common. Compulsion has become an important prerequisite to ensure the safety of cable underground operations

[0008] Current research often focuses on the installation and production tools of power cable intermediate joints and accessories, and less attention has been paid to the safety tools used in the construction process, especially the development of underground safety lamps for power cable wells.
