Insect repelling cable

Abstract

The invention relates to an insect repelling cable. The insect repelling cable comprises conductive wire cores, an insulating layer and a protective layer. The protective layer is externally wrapped by a repelling layer. Medicine rings are equidistantly installed in the axial direction in the repelling layer. Medicine spraying cavities made of elastic material are equidistantly arranged in the circumferential direction of each medicine ring. Each medicine spraying cavity is internally filled with insect repellents. A group of symmetrical internal walls of each medicine spraying cavity are also provided with closed spiral coils. The axes of the spiral coils are not parallel to the axes of the medicine rings. Each medicine spraying cavity is provided with an anti-blocking nozzle. Each anti-blocking nozzle outwardly extends along the radial direction of the medicine rings and stretches out to the external circumferential wall of the repelling layer. The cable is simple in structure with no requirement for frequency maintenance so that insects and ants around the cable can be effectively repelled and the service life of the cable can be effectively prolonged.

Description

technical field [0001] The invention relates to a cable, in particular to a buried cable capable of preventing insects. Background technique [0002] At present, there are two types of low-voltage power supply lines used for power supply in farmland: overhead lines and buried lines. Compared with overhead lines, buried lines have more advantages; buried lines do not need poles, porcelain insulators, pull wires, etc. when laying material, which can save a lot of cost; at the same time, the buried wire project is concealed, without criss-crossing wire nets and lined poles, so it will not affect field cultivation; in addition, the buried wire is placed underground to avoid natural disasters such as violent storms and heavy snow Therefore, it is more stable to use; however, the buried thread also has its disadvantages. Due to the complex field environment and many animals, the buried thread is often eaten and damaged by underground animals, such as common ants and mice, etc. ...

[0002] At present, there are two types of low-voltage power supply lines used for power supply in farmland: overhead lines and buried lines. Compared with overhead lines, buried lines have more advantages; buried lines do not need poles, porcelain insulators, pull wires, etc. when laying material, which can save a lot of cost; at the same time, the buried wire project is concealed, without criss-crossing wire nets and lined poles, so it will not affect field cultivation; in addition, the buried wire is placed underground to avoid natural disasters such as violent storms and heavy snow Therefore, it is more stable to use; however, the buried thread also has its disadvantages. Due to the complex field environment and many animals, the buried thread is often eaten and damaged by underground animals, such as common ants and mice, etc. The buried wires cause great damage and seriously affect the normal electricity consumption of residents; because the buried wires are buried underground, it is very inconvenient to repair the fault point; The process is more complicated
