Instant self-checking device for protective sleeve before cable use

Abstract

The invention relates to an instant self-checking device for a protective sleeve before cable use and belongs to the technical field of cable detection apparatuses. The device comprises a detection seat; a central positioning mechanism arranged on the detection seat; a driving ring rotatably connected to the inside of the detection seat; conversion gears uniformly engaged to the inner side of thedriving ring; light beam emitters corresponding to cables are evenly arranged on the detection seat; adjusting seats are connected to the light beam emitter; and photoresistors corresponding to the corresponding light beam emitters are arranged on the detection seat and the light beam emitters. According to the instant self-checking device for the protective sleeve before use of the cable, the detection seat, the light beam emitters and the photoresistors are combined with the central positioning mechanism, so that a cable which is slightly broken and damaged can be effectively prevented frombeing directly buried underground, and the quality of the buried underground cable is improved; the speed of corrosion and loss of the cable on the ground and the probability of problems of the cableare reduced, and meanwhile the risk of safety accidents and the frequency of detection and replacement of the underground cable are reduced.

Description

technical field [0001] The invention relates to the technical field of cable detection devices, in particular to an instant self-inspection device for a cable protective cover before use. Background technique [0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective sheath, which transmits power or information from one place to another. With the acceleration of urbanization and the improvement of overall environmental requirements, Many cables are used in the buried type, but buried cables are more troublesome in maintenance and replacement. Therefore, it is very important and necessary to reduce the probability of cable problems as much as possible. [0003] An effective measure to reduce the probability of cable problems is to ensure the quality of the cable. The protective sleeve is an important indicator of the quality of the cable. It mainly plays the role of protecting the internal conductor and is an important protective ...

Problems solved by technology

[0003] An effective measure to reduce the probability of cable problems is to ensure the quality of the cable. The protective sleeve is an important indicator of the quality of the cable. It mainly plays the role of protecting the internal conductor and is an important protective measure to ensure the normal and safe operation of the cable. Generally, the quality of the protective sheath will be tested before the cable enters the market during the production process, but during the transportation of the cable, some situations will cause the protective sheath to be damaged

[0004] However, slight damage to the surface of the protective cover will not affect the normal use of the cable, so people do not pay attention to the slight damage to the protective cover, but in fact, slight damage and damage will speed up the cable The life consumption of cables, especially for buried cables, will accelerate the rate of corrosion and loss of cables in the ground, greatly increasing the probability of cable problems, increasing the risk of safety incidents, and the maintenance of underground cables frequency of replacement
