A multifunctional agricultural cable

Abstract

The invention discloses a multifunctional farm cable, which comprises a cable main body, an earth wire, an outer insulating layer and a connection rib. The outer insulating layer wraps the outer side of the cable main body; the cable main body is connected with the earth wire through the connection rib; the cable main body is formed by a conductor, an internal insulating layer, a conductive line, a null line, control lines, a filling layer and an aluminum foil; the internal insulating layer wraps the outer side of the conductor; and the conductive line, the null line and the control lines are externally provided with the filling layer and are wrapped by the aluminum foil with the internal insulating layer together. According to the multifunctional farm cable, the cable main body is connected with the earth wire through the connection rib; the connection rib can be split to separate the earth wire from the cable main body; and the separated earth wire can be used for other purposes. The cable main body is of a flat structure, and is easy to lay, and besides, the insulating layer is made of a cross-linked polyethylene insulation material, so that the cable is resistant to high temperature, high voltage and corrosion, and is high in flexibility.

Description

technical field [0001] The invention relates to the field of cables, in particular to a multifunctional agricultural cable. Background technique [0002] In the past, when farmers were planting melons and fruits, they used plastic ropes or iron wires as fences and support frames for melons and fruits. It has been rusted, and many iron wires have been broken due to corrosion, and the tensile strength has dropped sharply. It needs to be replaced or re-lapped and erected, which is time-consuming and laborious. The rusty iron wires fell off in the leaves, roots and soil of the melons and fruits, which not only affected the growth environment of the melons and fruits, but also caused damage to the soil. In addition, summer is a period of frequent thunderstorms. The exposed iron wires are metal conductors, which are easy to conduct lightning. Farmers working in the fields are in danger of electric shock at any time. [0003] In recent years, many farmers use cables to set up mel...

Problems solved by technology

[0004] With the increasing application of heating cables in heating, farmers have also installed heating cables in vegetable greenhouses, Chinese herbal medicine greenhouses, and plant nurseries to extend the harvest period of vegetables and medicinal materials; the patent name of application number 201510222938.2 is "A Heating Cable" Just announce a kind of cable that can be used in agriculture and animal husbandry, it adopts the carbon fiber heating element and the first wire connection to be T-shaped, the carbon fiber heating element and the second wire connection are also T-shaped, and the two T-shaped It constitutes a double T-shaped structure, because there is a certain distance between the two T-shaped connections, which can effectively prevent the short circuit of the line and avoid unnecessary waste caused by the burning of the heating cable. However, this kind of cable structure is more complicated and expensive. Inconvenient and single-purpose
