Problems solved by technology

[0004] The purpose of the present invention is to solve the poor compressive resistance of the trench cover laid above the cable trench in the prior art, and it is difficult to improve its weighing capacity through the supporting frame. When the vehicle passes the trench cover many times, the trench cover is easy to appear Due to the disadvantages of structural damage such as cracks, a component-force compression-resistant cable trench is proposed

Abstract

The invention discloses a component-force compression-resistant cable trench, which comprises two side plates symmetrically distributed in the cable trench. The two side plates jointly support a trench cover plate, and the lower surface of the trench cover plate is embedded with a A magnetic plate is provided, and a slideway is opened in one of the side plates, and a wire is wound around the outside of the slideway. Reciprocating springs are fixedly welded on the top and bottom of the slideway, and between the two reciprocating springs A magnetic strip is placed vertically, and a protective plate is fixedly installed between the two side plates, and a circuit module and a plurality of solenoids are arranged inside the protective plate, and the circuit module is electrically connected with a wire. The invention transmits the pressure on the middle part of the trench cover to the protective plate, thereby improving the compressive capacity of the trench cover, and does not need a complicated frame structure to reinforce the trench cover, saving the inner space of the cable trench.

Description

Technical field [0001] The present invention relates to the technical field of electrical equipment, particularly to a compression force component cable trench. Background technique [0002] Common underground duct structure cable trench, cable ducts are mounted a plurality of cable holder, the cable may be arranged in layers is placed so that the cable laying more regular, above the cable channel be closed by a trench cover, the trench cover may be overhaul board open to facilitate staff access cable channel. [0003] Common trench cover for the pouring of concrete, with a certain strength, usually located on both sides of the road, can be used as a sidewalk, but compared to the normal terms of pavement, trench cover bearing capacity of poor, can not be used as a traffic lane Some drivers for quick overtaking or convenient Gasser, often ignoring the warning signage, secretly traveling on trench cover, causing structural damage trench cover appearance, and internal cable channel ...
