SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is exactly for solving current photovoltaic cable waterproof performance poor, the easy rusty problem of junction, provides a waterproof photovoltaic cable of suspension type direct current, can effectively avoid the junction to rust and the bad consequence that produces, guarantees the structural strength of junction, improves the security performance, also can improve the waterproof performance of cable simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a suspension type direct current waterproof photovoltaic cable comprises a conductor in the middle, wherein a group of protective sleeves are arranged outside the conductor, a waterproof layer is connected outside each protective sleeve, a group of waterproof cavities are arranged in each waterproof layer, and drying agents are arranged in the waterproof cavities and used for drying moisture permeating into the waterproof layers;
be equipped with a cable sheathing outside the waterproof layer, connect an annular fixing base on the cable sheathing, a waterproof dish is connected respectively to the both sides of fixing base, the edge of waterproof dish is towards the direction bending type who keeps away from the cable sheathing and is formed the portion of bending, connect a toper seat on the fixing base, form a water drainage tank between the edge of toper seat and the portion of bending of waterproof dish, one is connected at the middle part of toper seat and hangs the seat, hang fixed one on the seat and hang the ring, in order to be used for hanging of cable to erect.
Furthermore, the included angle alpha between the bending part and the horizontal direction is 30-45 degrees, so that the waterproof and drainage effects are achieved.
Further, the waterproof cavity is of a hollow spherical structure.
Furthermore, a layer of rubber ring is arranged between the fixing seat and the cable shell to strengthen connection, prevent direct contact between the fixing seat and the cable shell and reduce rusting.
Further, fixing base and waterproof dish adopt the haversian structure to loading and unloading and maintenance are convenient for.
Compared with the prior art, the utility model has the advantages of specifically lie in:
(1) the waterproof layer adopts a waterproof cavity structure, the desiccant is filled in the waterproof cavity, the waterproof layer serves as a first defense line to prevent the cable from water inflow, and when partial water vapor permeates into the waterproof layer through gaps among the materials, the desiccant in the waterproof cavity can dry the water vapor, so that the waterproof performance of the cable is improved;
(2) the waterproof disc structure with the cloak type is additionally arranged on the fixing seat connected with the cable, so that the lower connecting part can be effectively protected from being impacted by rain and snow, the rain and snow can be timely discharged through the drainage channel, and the situation that connecting equipment is rusted and broken is avoided.
