the cable protective sleeve 1 is provided with a plurality of cable separation areas through a separation plate 10;

the cable protection sleeve 1 is cylindrical and is provided with an upper opening and a lower opening, and is symmetrically divided into a left protection sleeve 11 and a right protection sleeve 12 along the axial direction of the cylinder;

a lug 13 is arranged at the corresponding position between the left protective sleeve 11 and the right protective sleeve 12;

through holes 14 are formed at two axial ends of the wall of the cable protective sleeve 1;

a liner is arranged on the inner side of the wall of the cable protective sleeve 1;

the limiting ring 2 is movably sleeved on the outer side of the cable protective sleeve 1;

the limiting ring 2 is in a circular ring shape, and the inner side of the circular ring is provided with an anti-collision ring which is coaxial with the limiting ring;

the brackets 3 are symmetrically distributed on two sides of the limit ring 2 and are used for fixedly connecting the limit ring 2 with the tower.

Specifically, two plate-shaped supports are respectively connected with two sides of two semicircular limiting rings to form a hollow cylindrical structure. The cable in the hollow cylinder is additionally provided with a cable protective sleeve 1. The two semi-cylindrical cable protection sleeves 1 which are symmetrical left and right are fixedly connected together by penetrating bolts at the lugs to form a hollow cylindrical structure. As shown in fig. 5, a plurality of cables generally penetrate through the tower from top to bottom in the height direction of the tower, a plurality of cable protection devices are twisted at intervals from top to bottom in the tower, and the cable protection devices are guaranteed to be provided with a plurality of cable protection devices along the wiring direction of the whole cable, so that the cable is protected in a limiting manner at a plurality of positions. Preferably, the support 3 is distributed on two sides of the ladder in the tower barrel, the support 3 extends to the wall of the tower barrel from the limiting ring 2 and then continues to extend to the wall of the tower barrel to be connected with the tower barrel, so that the reinforcing effect is provided for the ladder, and the fixing effect is provided for the twisted cable protection device. The preferred bracket 3 is a pair of parallel elongated plates sandwiching the stop collar 2.

The position of this protection device's confinement ring relative tower section of thick bamboo is fixed, and the cover has the cable protective sheath 1 of components of a whole that can function independently structure at interval inside, has accomplished to have protected the cable promptly, has restricted cable home range again. In order to protect the cable protective sheath 1 from damage caused by collision with the restraining ring, coaxial anti-collision rings are arranged at two ends of the restraining ring as shown in fig. 4, and are also arranged at two axial ends of the restraining ring on the radial inner side of the restraining ring. To ensure that the cable protective sleeve 1 contacts the anti-collision ring 21 first when moving, the material is preferably rubber or other materials capable of preventing collision and vibration.

The both sides symmetry of restriction ring 2 distributes and has support 3, and the welding of the both sides of restriction ring 2 has platelike support, and the spacing ring is connected to the one end of support, and the other end and the tower section of thick bamboo of support are fixed, and the preferred is fixed with the ladder of tower section of thick bamboo.

The cable sheath 1 is of a known split structure, and a splitter plate 10 is fixedly connected to the inside of the cable sheath, and the splitter plate 10 is of a plate shape arranged through the diameter of the splitter plate when viewed from the axial section of the cable sheath and axially penetrates through the cable sheath 1. The cylinder is divided into two semicircular cable separation areas, and the cables are distributed in the two cable separation areas, so that the cables are prevented from being bundled together and being overheated to cause fire. In order to ensure that the cable is not loosened in the cable protective sleeve, a gasket is arranged on the radial inner side of the cylinder wall of the cable protective sleeve 1, and the material is preferably wear-resistant and flame-retardant materials such as rubber.

In actual field construction, although the range of the cable protective sleeve 1 for binding the cable can be adjusted by the screw from the lug 13, it is inevitable to encounter a thinner cable. Therefore, two rows of circular through holes 14 are formed in the upper end and the lower end of the cable protective sleeve in a circular array mode, the through holes can play a role in heat dissipation, on the other hand, an upper row of through holes 14 and a lower row of through holes 14 are formed in each end of the cable protective sleeve 1, and a cable tie for binding and fixing the cable, which is known in the art, can penetrate through the upper corresponding through holes 14, the lower corresponding through holes 14 or two adjacent through holes 14 in the same axial position to further fix the cable. The utility model discloses compare with prior art every with the cable all need pass an independent through-hole, the threading is efficient.

The partition plate 10 has a through hole penetrating vertically at the cylinder axis. In particular, the partition plate 10 arranged at the diameter of the cylinder is designed in a split type, that is, two partition plates 10 are provided, one side of each partition plate 10 is fixedly connected with the inside of the cylinder, and the other side is arranged with a space with the other partition plate 10. When the partition plate 10 is of an integral structure, both sides of the partition plate are fixedly connected with the inner wall of the cylinder, and the partition plate 10 is difficult to mount if the width of the partition plate 10 is larger than the diameter of the cylinder during mounting. The split structure is not easy to cause the problem, and a gap is formed between the two partition plates 10, so that the heat dissipation effect can be achieved.

Preferably, the partition plate is arranged at the diameter of the cylinder, but in order to increase the heat radiation effect of the partition plate 10, the partition plate 10 may be perforated with heat radiation holes.

The axial height of the cable sheath 1 is greater than the axial height of the confinement rings 2.

Specifically, for the activity of better restriction cable protection sleeve 1, cable protection sleeve 1's length obviously is longer than the height of spacing ring 2, and prefers spacing ring 2 and arrange cable protection sleeve 1's axial intermediate position in, and when cable protection sleeve 1 of being convenient for had certain rocking, spacing ring 2 still can wear and play limiting displacement in cable protection 1's outside.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
