Insect repellent cable

Abstract

The invention relates to an insect-repelling cable, which includes a wire core, an insulating layer and a protective layer; a repelling layer is wrapped outside the protective layer, and the repelling layer is installed equidistantly in the axial direction in the repelling layer There are drug rings, and drug spraying chambers made of elastic materials are equidistantly arranged in the circumferential direction of each drug ring, and insect repellants are filled in each of the drug spraying chambers; A closed helical coil is also installed on the symmetrical inner wall of the group, and the axis of the helical coil is not parallel to the axis of the drug ring; anti-clogging nozzles are provided on each of the spray chambers, and each of the anti-clogging nozzles is arranged along the drug ring. The radial direction extends outward and extends to the outer peripheral wall of the repelling layer; the cable has a simple structure and does not require frequent maintenance, which can effectively drive away insects and ants around the cable and effectively prolong the service life of the cable.

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. Th...

[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
