However, the patent still has the following problems in actual use:

[0003] Existing waterproof materials all have a certain service life. When cables are damaged due to dragging, aging, etc., which is difficult to detect, their external waterproof effect will also be reduced. At this time, external moisture may penetrate into the cable through the damaged area and cause leakage. The existing cable waterproof structure and protective structure will immediately lose their protective effect when the outside of the line is damaged, and lack the corresponding automatic remedial function.

[0004] A water-blocking aluminum alloy cable is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a water-blocking aluminum alloy cable to solve the problem that the waterproof structure and protective structure of the existing cables proposed in the above-mentioned background technology immediately lose their effectiveness when the outer side of the line is damaged and lacks the corresponding automatic remedial function.

[0006] To achieve the above object, the utility model provides the following technical solution: a water-blocking aluminum alloy cable, comprising a main cable and a branch cable, wherein the main cable and the branch cable are fixedly connected by a connector;

[0007] The main cable includes a plurality of aluminum alloy rope bodies, a shielding layer is fixedly connected to the outside of some of the aluminum alloy rope bodies, a sponge gasket is fixedly connected to the outside of the shielding layer, a spiral steel wire ring is wound around the outside of the sponge gasket, and a supporting steel wire is fixedly connected to the outside of the spiral steel wire ring.

[0008] Preferably, a first plastic plate is fixedly connected to the outer side of the supporting steel wire, and a second plastic plate is fixedly connected to the outer side of the first plastic plate.

[0009] Preferably, two ends of the first plastic plate and the second plastic plate are fixed to each other, a cavity is provided between the first plastic plate and the second plastic plate, and the cavity is filled with liquid waterproof glue.

[0010] Preferably, a hydrophobic sleeve is fixedly connected to the outside of the second plastic plate, a wear-resistant sheath is fixedly connected to the outside of the hydrophobic sleeve, and the first plastic plate and the second plastic plate are both made of soft PVC plastic.

[0011] Preferably, a waterproof coating is filled between the supporting steel wire and the spiral steel wire ring.

[0012] Preferably, an anti-wear structure is provided on the side of the branch cable, and the anti-wear structure includes a lower clamping ring fixedly connected to the connecting piece, the lower clamping ring is located below the branch cable, the lower clamping ring is rotatably connected to the upper clamping ring, and the upper clamping ring is connected to the lower clamping ring by bolts.

[0013] Preferably, the upper clamping ring and the lower clamping ring are both threadedly connected to a moving knob, one end of the moving knob is rotatably connected to a sponge clamping ring, and the sponge clamping ring is fitted with the connecting piece.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the water-blocking aluminum alloy cable allows the liquid waterproof glue to contact with the outside air and harden during the overflow process, and finally fills up the gaps and other damaged parts, so that the outside moisture and air cannot enter the main cable, and automatically fills up the invisible leakage gaps on the outside of the main cable, thereby increasing the service life of the entire main cable and avoiding the failure of the waterproof function due to the small gaps, thereby preventing leakage. The specific contents are as follows:

[0015] 1. When the main cable is damaged, it means that the second plastic plate, the hydrophobic sleeve, and the wear-resistant sleeve are all damaged. At this time, the liquid waterproof glue between the second plastic plate and the first plastic plate slowly seeps outward, and as the liquid waterproof glue comes into contact with the outside air at the damaged part, the liquid waterproof glue hardens during the overflow process, and finally fills the gaps and other damaged parts, resulting in the inability of external moisture and air to enter the main cable, and automatically completes the filling of the invisible leakage gaps on the outside of the main cable, thereby increasing the service life of the entire main cable and avoiding the failure of the waterproof function due to small gaps, thereby causing leakage.

[0016] 2. After the lower clamping ring and the upper clamping ring are clamped, the moving knob is rotated so that the sponge clamping ring presses the edge of the branch cable from the upper and lower sides, thereby reducing the friction of the branch cable at the connection between the branch cable and the connector when the branch cable is bent, thereby reducing its wear degree.

[0027] The two ends of the first plastic plate 107 and the second plastic plate 108 are fixed to each other, and a cavity is provided between the first plastic plate 107 and the second plastic plate 108, and the cavity is filled with liquid waterproof glue 109; the liquid waterproof glue 109 is liquid under normal conditions, and will overflow from the first plastic plate 107 or the second plastic plate 108 only when the device is damaged, until the liquid waterproof glue 109 is completely solidified in the crack, isolating the inside and outside of the main cable 1, forming a re-seal, and the remaining liquid waterproof glue 109 will stop solidifying.

[0028] The hydrophobic cover 110 is fixedly connected to the outside of the second plastic plate 108, and the wear-resistant cover 111 is fixedly connected to the outside of the hydrophobic cover 110. The first plastic plate 107 and the second plastic plate 108 are both made of soft PVC plastic. The first plastic plate 107 and the second plastic plate 108 are soft and can be bent with the cable. The hydrophobic cover 110 has the thickest thickness and the most direct waterproof effect. The wear-resistant cover 111 can reduce the wear of the cable.

[0029] A waterproof coating 106 is filled between the support steel wire 105 and the spiral steel wire ring 104 . The waterproof coating 106 is an epoxy resin coating, which reduces the possibility of water seepage in the gap between the support steel wire 105 and the spiral steel wire ring 104 .

At this time, the liquid waterproof glue 109 between the second plastic plate 108 and the first plastic plate 107 slowly seeps outward, and as the liquid waterproof glue 109 contacts the outside air at the damaged part, the liquid waterproof glue 109 hardens during the overflow process, and finally fills the gap and other damaged parts, so that the outside moisture and air cannot enter the main cable 1;

[0032] After the lower clamping ring 301 and the upper clamping ring 302 are clamped, the moving knob 303 is rotated to make the sponge clamping ring 304 press the edge of the branch cable 201 from the upper and lower sides, thereby reducing the friction of the branch cable 201 at the connection between the branch cable 201 and the connector 2 when the branch cable 201 is bent, thereby reducing its wear degree.
