Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a layered anti-corrosion power cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. However, some of the power cable applications have harsh environments, such as seawater and being buried underground. The surface of the cable may be in contact with moisture for a long time, making the cable susceptible to corrosion, which reduces the service life of the cable. Therefore, a layered anti-corrosion power cable is needed to solve the above problems. Utility Model Content

[0005] As a preferred implementation, the second sealing gasket is sleeved outside the wire core, and two of the second sealing gaskets are respectively arranged in the first position limiting tube and the second position limiting tube.

[0006] As a preferred implementation, the connecting pipe is sleeved outside the protective sleeve.

[0007] As a preferred implementation, the cross-sectional shapes of the connecting tube, the first limiting tube and the second limiting tube are all set to be circular.

[0008] As a preferred embodiment, the first sealing gasket and the second sealing gasket are both circular in shape.

[0009] As a preferred embodiment, the shapes of the threaded tube and the thread groove are both circular.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model connects a plurality of connecting tubes sleeved on the outside of the cable through a threaded tube and a threaded groove, and a first limiting tube and a second limiting tube are both connected to two connecting tubes at two ends through the threaded tube and the threaded groove. At this time, a protective structure formed by the first limiting tube, the second limiting tube, a plurality of first sealing pads, two second sealing pads, a plurality of threaded tubes and a plurality of threaded grooves cooperating with each other can separate external water from the cable, so that the cable is not easily corroded due to contact with moisture, and the protective structure sleeved on the outside of the cable can block foreign objects, so that foreign objects are not easily in direct contact with the cable and thus damage it, thereby ensuring the normal service life of the cable.

[0012] The utility model is provided with a threaded pipe, a threaded groove and a first sealing gasket. When the threaded pipe is threadedly connected in the threaded groove and the first sealing gasket is in contact with the threaded groove, the first sealing gasket can seal the gap between the threaded pipe and the threaded groove, so that the two connecting pipes can be connected together with a high sealing, and it is not easy for external moisture to enter the interior of the connecting pipe through the gap.

The cable 1 includes a wire core 101 and a protective sleeve 102. The protective sleeve 102 is connected to the outside of the wire core 101. The first limiting tube 2 and the second limiting tube 3 are close to each other. The side is connected to the second sealing pad 8, and the second sealing pad 8 is sleeved on the outside of the wire core 101. The two second sealing pads 8 are respectively arranged in the first limiting tube 2 and the second limiting tube 3. The two second sealing pads 8 are overlapped at both ends of the protective sleeve 102. The same side of the position tube 2 and the plurality of connecting tubes 4 is provided with a threaded groove 7, the connecting tube 4 is sleeved outside the protective sleeve 102, the other side of the second position limiting tube 3 and the plurality of connecting tubes 4 is connected with a threaded tube 5, the threaded tube 5 is threadedly connected in the threaded groove 7, and the threaded tube 5, the threaded groove 7 and the first sealing gasket 6 are provided. When the threaded tube 5 is threadedly connected in the threaded groove 7 and the first sealing gasket 6 contacts the threaded groove 7, the first sealing gasket 6 can seal the gap between the threaded tube 5 and the threaded groove 7, so that the two connecting tubes 4 can be connected together with high sealing, so that it is not easy for external moisture to enter the interior of the connecting tube 4 from the gap;

[0023] The threaded tube 5 is connected to the first sealing gasket 6, and the first sealing gasket 6 is overlapped in the thread groove 7. By setting the thread groove 7 and the threaded tube 5, the threaded tube 5 and the thread groove 7 cooperate with each other to connect two adjacent connecting tubes 4, the connecting tube 4 and the first limiting tube 2, and the connecting tube 4 and the second limiting tube 3 together;

By setting the second sealing gasket 8, the second sealing gasket 8 can seal the gap between the protective sleeve 102 and the first position-limiting tube 2 or the second position-limiting tube 3, so that external moisture is not easy to enter the first position-limiting tube 2 and the second position-limiting tube 3;

[0025] The shapes of the threaded tube 5 and the thread groove 7 are both circular.

[0026] The working principle and use process of the utility model are as follows: when the cable 1 needs to be used, several connecting tubes 4 are sleeved on the outside of the cable 1, and the threaded tubes 5 in the several connecting tubes 4 are all threadedly connected in the adjacent threaded grooves 7, and the first sealing gasket 6 connected to the threaded tube 5 is in contact with the threaded groove 7, and then the first limiting tube 2 and the second limiting tube 3 are respectively sleeved on the outside of the cable 1, so that the first limiting tube 2 and the second limiting tube 3 are both brought to the second sealing zone to contact the two ends of the protective sleeve 102 respectively, and then the first limiting tube 2 and the second limiting tube 3 are threadedly connected to the two connecting tubes 4 at the two ends. At this time, the protective component composed of the first limiting tube 2, the second limiting tube 3, the first sealing gasket 6, the two second sealing gaskets 8, the threaded tube 5 and the threaded groove 7 can separate the external water from the cable 1, so that the cable 1 is not easily corroded due to contact with moisture.
