Problems solved by technology

The current cable well covers are generally made of reinforced concrete. After covering, the situation in the ditch cannot be directly inspected. The cover must be opened when necessary, which increases the workload of power cable inspections, resulting in inadequate inspections and maintenance inspections due to small animals. Accidents happen from time to time
[0003] The defective of prior art: (1) maintenance work is loaded down with trivial details
(2) heavy operation
(4) Easy to damage when pried up

Abstract

The invention discloses a cable working well lid. The cable working well lid comprises a base frame and a transparent substrate. The base frame is arranged at the wellhead part of a cable working well. The transparent substrate is arranged on the base frame. Spacing holes are formed in the transparent substrate. Fixing holes are formed in the base frame. The spacing holes are in butt joint with the fixing holes in a matching manner, and external bolts penetrate through the spacing holes. Anti-theft bolt reserved holes are formed in the base frame. The visual degree of a cable pipe trench is enhanced greatly by virtue of the transparent well lid, so that operating personnel can grasp the situation of facilities, such as an in-trench cable, a bracket and a grounding device, without opening a lid plate, the power cable line inspection efficiency is improved, and a guarantee is provided for the safe operation of the cable line is ensured.

Description

technical field [0001] The present invention relates to cable wells. Background technique [0002] Power cables are generally installed in cable trenches, and power covers are laid at intervals in the cable trenches to facilitate subsequent maintenance. The current cable well covers are generally made of reinforced concrete. After covering, the situation in the ditch cannot be directly inspected. The cover must be opened when necessary, which increases the workload of power cable inspections, resulting in inadequate inspections and maintenance inspections due to small animals. Accidents happen from time to time. [0003] The defective of prior art: (1) maintenance work is loaded down with trivial details. (2) The operation is heavy. (3) Not anti-theft. (4) It is easily damaged by prying. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a cableman's manhole cover, which is convenient for power cable inspection...
