Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

Some embodiments of the present invention provide a preset channel cover plate of sensing line, as shown in fig. 1, the channel cover plate includes a cover plate body 10, as shown in fig. 2 and 5, a plurality of parallel H-shaped steels 11 arranged in the cover plate body 10 are provided in the cover plate body 10, and with reference to fig. 2, in some preferred embodiments, two adjacent H-shaped steels 11 have a distance H between upper flanges₁Equal to the width H of the upper flange of the I-shaped steel 11₂Wherein the widths of the upper flange and the lower flange are equal; the distance between two I-shaped steels is limited, the anti-damage performance of the channel cover plate is improved more remarkably, and the distance H from the periphery of the area formed by the I-shaped steels 11 to the edge of the cover plate body 10 is₃Equal, preferably, H₃＝1.5H₂. As shown in fig. 3 and 6, a wire slot 12 is formed at the bottom of the cover plate body 10, a sensing wire 13 is preset in the wire slot 12, the sensing wire is an enameled wire, as shown in fig. 1, 2, and 4, an insulating glue layer 14 is encapsulated outside the wire slot 12, referring to fig. 3, two ends of the sensing wire 13 are connected with sensing wire connectors 15, and the sensing wire connectors 15 are preferably aviation connectors 15The sensor wire connector 15 extends from the bottom of the cover body 10, with continued reference to fig. 1. The extended sensing line joint is connected with a detection device through another joint, and then the damage and the uncovering state of the channel cover plate are detected.
