Problems solved by technology

The existing trench cover plates are made of cement reinforced concrete and polymer composite materials, etc., but because they are exposed to the outside for a long time and are subjected to mechanical forces such as rolling, handling, and prying for a long time, they are very easy to be damaged, and the work is difficult. Personnel are regularly overhauled, it is not

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the drawings and the following embodiments.

[0036] One embodiment of the present invention provides a channel cover plate, which is used in a detection device for mechanically destroying the cover plate or opening the cover, such as figure 1 As shown, the channel cover includes a channel cover body 10 and a wire 20 arranged in the channel cover body 10, wherein the material of the wire 20 is preferably copper wire, wrapped with a moisture-proof insulating layer, and the wire 20 is The thickness is variable, but it needs to be disconnected when the channel cover body 10 is mechanically damaged; the wire 20 is set in the channel cover body 10 by casting; continue to refer to figure 1 In some preferred embodiments, in order to improve the sensitivity of detection, the overall arrangement of the wire 20 is an undercut shape. The channel cover plate provided by the present invention is provided...

Abstract

The invention provides a trench cover plate and a detecting device for mechanical damage to a cover plate or uncovering. The trench cover plate comprises a trench cover plate body, a wire arranged inthe trench cover plate body, a first resistor connected in parallel with the wire through a first connector, and a connector connected to the wire; and according to the trench cover plate, the damageor uncovering situation of the trench cover plate can be determined according to the on-off state of the wire and a resistance value of a main loop, so that the convenience in detection is improved.

Description

Technical field [0001] The invention belongs to the technical field of channel cover plates and detection, in particular to a channel cover plate and a detection device for mechanically destroying the cover plate or opening the cover. Background technique [0002] There are a large number of cables and optical cable channels in power generation facilities. In order to ensure the safety of cables and optical cables in the channels, avoid aging caused by direct sunlight, and prevent rain, dust, and debris from falling into the channels, protection must be provided on the channels. The role of channel cover. The existing channel cover plates are made of cement reinforced concrete and polymer composite materials, but they are very easily damaged due to long-term exposure to the outside and long-term mechanical forces such as rolling, handling, and prying. It is not easy to detect the damage of the trench cover plate in time for personnel to check and repair regularly; in order to de...
