Technical Field

The invention relates to the technical field of electrical installation, in particular to a novel cable trench cover plate with an automatic illumination function.

Background

In electric power system, the distribution is the link that directly links to each other and distribute the electric energy to the user, and electricity is inseparable with the production life, and consequently power cable's laying protection is just more important, and power cable generally lays in the cable pit and fixes, for preventing rainwater and illumination damage cable, influences the cable life-span, and the cable pit top is equipped with the cement apron, and the cement apron both can protect the cable, also makes things convenient for the cable to maintain.

The cable trench cover plate of the transformer substation plays a role in preventing small animals from entering and bearing, the cable trench cover plate of the transformer substation at present all uses a cement cover plate, because of compact arrangement and self weight, the cement cover plate is generally heavier, about sixty-seven jin is provided, the cement cover plate is difficult to move during maintenance or repair, two male members must be configured, because of lacking of an acting point, the safety of personnel is difficult to ensure in the uncovering and covering processes, the workload is large, the working efficiency is low, the inspection time is prolonged, the maintenance personnel are easy to be injured by smashing or clamping, certain potential safety hazard is provided, and great burden is caused to inspection of the operation and maintenance personnel of the transformer substation; meanwhile, the moving method has large workload and low working efficiency, and the edge of the cover plate is easy to damage or even the cover plate is broken by prying the cement cover plate by using a hard object, so that the service life of the cable trench cover plate is influenced. In order to facilitate prying of the cement cover plate, the surface of the cover plate is provided with a convex part for prying, but the convex part is easy to cause a walker to fall down, so that certain potential safety hazards are generated.

Moreover, the cable trench cover plate made of cement or metal materials is not transparent, so that the operation conditions of cables and other equipment in the trench cannot be observed and mastered in time by inspection personnel; so that the phenomenon that the cable insulation sheath cannot be found for a long time due to burning loss occurs, and hidden danger is brought to safe production. In addition, because the inside lighting apparatus that does not have of cable pit, light is not enough, has increased the inside inspection of cable pit and the degree of difficulty of maintaining. Therefore, the cable trench cover plate used at present is not ideal in structural design and is expected to be further improved.

Disclosure of Invention

The invention aims to provide a novel cable trench cover plate with an automatic illumination function, aiming at the defects that the cable trench cover plate is not easy to move, cannot illuminate, is easy to cause stumbling of walking personnel and does not have a transparent observation port in the prior art.

The above object of the present invention is achieved by the following scheme:

A novel cable trench cover plate with an automatic illumination function comprises a frame type base and a cover plate; the frame type base is concave, and the cover plate is fixed in the concave part of the frame type base; the cover plate comprises a cover plate, a cover plate and a cover plate which are hinged in sequence, and the cover plate is a transparent cover plate;
