Pre-embedded warning type anti-stamping unloading protection mechanism for power cable

Abstract

The invention discloses a pre-embedded warning type anti-stamping unloading protection mechanism for a power cable, and the mechanism comprises a foundation pit channel, a supporting rod, an air sealing block and a positioning cavity; positioning plates are fixedly installed on the left side and the right side of the top of the foundation pit channel, an inner hollow shell is fixed to the top of each positioning plate, a sliding block is installed on the outer wall of the supporting rod in a penetrating mode, an isolation soft strip is fixed to the penetrating connection position of the sliding block and the supporting rod, a vertical rod is fixedly connected between the ends, located in the supporting rod, of the sliding block, a telescopic rod is fixed to the lowermost portion in the supporting rod, and the upper end of the telescopic rod is connected with the lower end of the vertical rod; and the interior of the telescopic rod is in through connection with the interior of the inner hollow shell through a threaded hose. According to the pre-embedded warning type electric power cable anti-stamping force unloading protection mechanism, comprehensive protection of the position where the cable is located can be carried out, stamping resistance and pressure relief of stamping external force and positioning adjustment protection of the cable can be carried out, and warning processing can be carried out when the cable is excavated and stamped.

Description

technical field [0001] The invention relates to the technical field related to cables, in particular to a pre-embedded warning type power cable anti-punching force unloading protection mechanism. Background technique [0002] The development of information technology is inseparable from the transmission and exchange of remote information. In today's modernization, in order to meet the needs of good communication and data information exchange between different urban areas, it is necessary to set up embedded cables for information communication. The pre-embedded setting of bridges and cables can greatly reduce the space occupation caused by the volume of information, and avoid the disorder of the available space in the city caused by its messy cross distribution. In order to effectively reduce the anti-excavation of cables during pre-embedded processing damage, it is necessary to install a protective mechanism outside the pre-embedded area of ​​the cable. [0003] However, th...

Problems solved by technology

[0007] The purpose of the present invention is to provide a pre-embedded warning type power cable anti-punching force unloading protection mechanism to solve the above-mentioned background technology. It is proposed that the existing cable protection mechanism only uses its own strength to protect the cable against excavation impact. It is easy to cause its own strength to be damaged, resulting in cable breakage and damage, and its protection stability and impact resistance are not strong. The pressure caused by excavation is leaked and displayed, which will cause continuous punching due to excavation, and eventually cause the mechanism to resist compression and damage, and the functionality and efficacy of its use are insufficient.
