Problems solved by technology

[0002] The power machinery used in coal storage places usually needs to use special cables for power supply, while the coal stored in the open air and the cables of mechanical equipment need to adapt to the possible moisture problems in open air. The existing cables have simple structures, limited strength, and are easy to use. Damaged and exposed phenomena due to extrusion and other conditions, resulting in moisture in the cable and other conditions, are prone to short circuits

Embodiment 1

[0018] Such as figure 1 As shown, a coal yard mechanical moisture-proof and pressure-resistant cable includes at least three aluminum alloy conductors 101 and an insulating layer 102 arranged outside the aluminum alloy conductors 101. Above, an eyelet layer 104 is arranged outside the aluminum alloy wire 101, a rubber cushion layer 105 is arranged inside the eyelet layer 104, and a helical row is arranged on the inner wall of the rubber cushion layer 105. The groove of the cloth, the outer wall of the insulating layer 102 is attached to the inner side of the groove, the outer insulating layer 106 is arranged outside the metal ring layer 104, and the outer wall of the rubber cushion layer 105 is arranged There are concave structures 107 arranged in a spiral direction, and sponges are filled inside the concave structures 107, and the spiral direction of the concave structures 107 is opposite to that of the grooves.

[0019] When the present invention is subjected to external ex...

Embodiment 2

[0021] In order to improve the moisture-proof performance of the overall structure, in this embodiment, on the basis of Embodiment 1, preferably, a bamboo charcoal layer 108 is sheathed outside the eyelet layer 104 . By using the bamboo charcoal layer, it can absorb external moisture. Since the bamboo charcoal has a reversible moisture absorption effect, after a period of use, the moisture on the corresponding parts of the bamboo charcoal can be volatilized by drying.

[0022] In this embodiment, preferably, the eyelet layer 104 is a sheet metal strip wound helically on the outer wall of the rubber cushion layer 105 . By adopting a spiral winding manner, the production of the eyelet layers can be facilitated, and at the same time, the strength of the eyelet layers can be enhanced by covering and winding each other.

[0023] In order to improve the tensile performance of the cable, in this embodiment, preferably, the helical winding direction of the eyelet layer 104 is opposite...

Abstract

The invention discloses a moisture-proof and pressure-resistant cable for coal yard machinery, which comprises at least three aluminum alloy wires and an insulating layer arranged outside the aluminum alloy wires. The above-mentioned aluminum alloy wire is provided with a metal ring layer outside, and a rubber pad is provided inside the metal ring layer, and the inner wall of the rubber pad is provided with grooves arranged in a spiral shape. The outer wall of the layer is attached to the inner side of the groove, an outer insulating layer is arranged outside the metal ring layer, and a concave structure arranged in a spiral direction is arranged on the outer wall of the rubber cushion layer. The inside of the concave structure is filled with sponge, and the helical direction of the concave structure is opposite to the helical direction of the groove. The present invention realizes the hygroscopic effect by adopting the rubber pad layer provided with the sponge layer, and prevents the cable from getting damp.

Description

technical field [0001] The invention relates to a coal yard mechanical moisture-proof and pressure-resistant cable. Background technique [0002] The power machinery used in coal storage places usually needs to use special cables for power supply, while the coal stored in the open air and the cables of mechanical equipment need to adapt to the possible moisture problems in open air. The existing cables have simple structures, limited strength, and are easy to use. Due to damage and exposure due to extrusion and other conditions, the cable is damp and other conditions are prone to short circuits. Contents of the invention [0003] The purpose of the present invention is to provide a moisture-proof and pressure-resistant cable for coal yard machinery, which can improve the problems existing in the prior art. By using a rubber cushion layer provided with a sponge layer, the moisture absorption effect can be realized and the cable can be prevented from being damp. [0004] Th...
