Description
Technical Field
The utility model relates to the technical field of cables, specifically be an agricultural irrigation cable.
Background
Agricultural irrigation mainly refers to irrigation operation performed on agricultural cultivation areas. Agricultural irrigation methods can be generally divided into traditional ground irrigation, general sprinkler irrigation and micro-irrigation. Traditional ground irrigation includes furrow irrigation, flood irrigation and flood irrigation. The modern agricultural micro irrigation technology comprises micro-sprinkling irrigation, drip irrigation, infiltration irrigation and the like. The irrigation technologies generally have good water-saving performance and higher water utilization rate than the traditional irrigation mode. Agricultural irrigation equipment cable, according to different service environment, can design out the cable of different performance, traditional agricultural irrigation equipment cable structure and performance are comparatively single, and have some corresponding fertilizers to spill in the farmland when agricultural irrigation, fertilizer mostly is the corrosivity stronger, traditional cable corrosion resistance is relatively poor, after agricultural irrigation equipment used up the cable, need retrieve the cable, current cable if submergence is in aquatic, bring very big inconvenience to the recovery work, we propose an agricultural irrigation cable for this reason and be used for solving above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an agricultural irrigation cable to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an agricultural irrigation cable, includes the wire, the outer parcel of wire has the filling layer, the outer parcel of filling layer has the PVC insulating layer, the outer parcel of PVC insulating layer has the electromagnetic shield layer, the outer parcel of electromagnetic shield layer has the polyvinyl chloride insulating layer, cavity in the polyvinyl chloride insulating layer is equipped with the cavity post, the fixed mounting has the elasticity valve in the cavity post, the outer parcel of polyvinyl chloride insulating layer has the mica tape layer, the outer parcel of mica tape layer has the polyethylene insulating layer, the outer parcel of polyethylene insulating layer has outer inoxidizing coating.
Preferably, the filling layer is a glass fiber material.
Preferably, the electromagnetic shielding layer is a metal mesh structure.
Preferably, the elastic valve comprises a thick elastic block, a thin elastic block is fixedly connected in the thick elastic block, and a crack is arranged at the center of the thin elastic block in a penetrating manner.
Preferably, the elastic valve is circular, and the slit is in a straight line shape.
Preferably, the conduction threshold of the crack is greater than the standard atmospheric pressure.
Compared with the prior art, the beneficial effects of the utility model are that: the appropriate amount of gas with density smaller than that of air is filled into the hollow column, when the cable is used, the cable can float on the water surface due to the hollow column, the cable is convenient to recover after being used in the later period, and meanwhile, the multi-layer insulation structure can be more corrosion-resistant and has better insulation; the crack of the elastic valve can facilitate the gas injection when the gas charging device charges gas, and when the charging is finished, the gas is not easy to leak under the action of external pressure and the material of the elastic valve, so that the gas in the hollow column is kept.
