A cable anti-digging alarm device

Abstract

An anti-digging alarm device for cables, which relates to the field of cable protection. The invention provides a second storage box on the first storage box, the first storage box and the second storage box are connected by threads, and the first storage box A disc is arranged inside, a connecting body is arranged on the disc, a gear is arranged on the connecting body, a sealing cover, a smoke outlet pipe and a support column are arranged on the second storage box, a rack is arranged on the sealing cover, and the rack and the gear are meshed to support A clamping device is arranged on the column, and the clamping device includes two semicircular hoops, two semicircular hoops are respectively provided with second connecting ears, and the two second connecting ears are respectively provided with first round holes. The structure of the present invention It is reasonable and practical, and it is very convenient to use. By installing an alarm device on the cable duct, the alarm device will generate a lot of smoke after being triggered, reminding the operators to work carefully. After the construction is completed, the alarm device can be installed and restored, that is, the underground cable is protected in advance , and also warn workers to be careful.

Description

technical field [0001] The invention relates to the technical field of cable protection, in particular to a cable anti-digging alarm device. Background technique [0002] As we all know, with the continuous development of social economy, the use of electricity is also increasing. Compared with common overhead lines, cables are often buried underground, so they are also called underground cables. Due to the shortage of urban land and heavy traffic pressure, At present, most cities generally adopt the underground cable transmission mode for reasons such as cityscape construction. Underground cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. Now, when underground cables are buried, the cables are generally installed in pipes and then laid. , When it is necessary to develop and transform a certain area, construction operations are often carried out. Although there are clear operating procedures and regulations for e...

[0002] As we all know, with the continuous development of social economy, the use of electricity is also increasing. Compared with common overhead lines, cables that are often buried underground are also called underground cables. Due to the tight urban land use and heavy traffic pressure, For reasons such as city appearance construction, most cities currently use underground cable transmission. Underground cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. Nowadays, when underground cables are buried, they are generally installed in pipes and then laid. , when it is necessary to develop and transform a certain area, construction work is often carried out. Although there are clear operating procedures and regulations for excavating areas with underground cables, they are often not paid attention to in actual operations. During construction, due to The cable is underground, so it is difficult to judge its location. Once large-scale mechanical excavation is used, and the cable equipment management personnel are not present to guide the construction, etc., the operator will accidentally injure the cable or even dig it off. This not only affects the normal operation progress, but also requires professionals It is a waste of time to repair, and digging out the cable will cause major accidents. In the lightest case, it will affect the normal electricity consumption of nearby residents, causing economic losses in production and life. security violation of criminal law
