Description

Technical Field

[0001] The utility model relates to a cable protector and belongs to the technical field of power transmission accessories. Background Art

[0002] In power transmission, especially long-distance power transmission, in order to reduce the weight of the cable and facilitate heat dissipation, the surface of the cable is not provided with an insulating sheath. When the cable is close to the tower or pole, two insulators are used to fix the cables on both sides respectively. Between the two insulators, a connecting cable with a relatively wide structure is used to connect the cables fixed to the insulators on both sides. When the wind blows the cable to swing, if the swing amplitude of the connecting cable connecting the two insulators is large, it may collide with the crossarm on the tower or pole, thereby damaging the cable, and it is easy to conduct the current to the ground through the tower or pole, posing a safety risk to pedestrians passing below. If an insulating protective pad is directly wrapped on the cable, the heat generated by the power-on of the cable is not easy to dissipate, which also affects the safety of power transmission. Summary of the invention

[0003] The purpose of the utility model is to provide a cable protector to solve the technical defects in the prior art that when the cable is blown by the wind and swings, the part near the iron tower or the electric pole (that is, the connecting cable connected to the cables fixed with two insulators) collides with the cross arm of the iron tower or the electric pole, which is easy to damage the connecting cable, while directly wrapping the protective pad on the connecting cable is not conducive to the heat dissipation of the connecting cable.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a cable protector, including a protector body, the protector body is used to wrap around the cable line when in use, a through groove is opened on one side of the protector body along the length direction, and more than two fixing members are arranged on the protector body at intervals along the length direction of the through groove, and at least one fixing member is arranged at each end of the protector body, the fixing members are used to press the protector body from both sides of the through groove towards each other when in use, and at least one heat dissipation hole group is opened on the protector body along the circumferential direction. When the utility model is in use, it is fixed on the exposed cable line near the iron tower or the electric pole (that is, the connecting cable connected to the cable fixed with two insulators, and the cables mentioned below that need to fix the utility model are all connecting cables). When the cable is blown by the wind and the cable line swings, and the cable line collides with the iron tower or the cross arm of the electric pole, the cable line and the iron tower or the cross arm of the electric pole are separated, so as to protect the cable and avoid damage to the cable line due to the collision with the iron tower or the cross arm of the electric pole. The heat generated by the cable line when transmitting electricity can be dissipated from the heat dissipation holes on the protector body, so as to avoid heat accumulation and improve the safety of power transmission.

[0005] As a further improvement of the utility model, each heat dissipation hole group includes at least one heat dissipation hole, and the heat dissipation holes in each heat dissipation hole group are arranged at intervals along the length direction of the protector body. The distribution of the heat dissipation holes in the utility model is more conducive to the dissipation of heat generated by the cable.

[0006] As a further improvement of the utility model, the two sides of the through slot on the protector body protrude in a direction away from the center line of the protector body to form a fixing protrusion, and the fixing protrusions on both sides of the through slot are correspondingly provided with fixing through holes, and the fixing members are bolts passing through the fixing through holes on the fixing protrusions on both sides of the through slot and nuts matching with the bolts. The utility model sets a fixing protrusion on the protector body, and by passing through the bolts of the fixing protrusions and the nuts matching with the bolts, the fixing protrusions on both sides of the through slot are pressed together, thereby tightly fixing the protector body on the cable line.

[0007] As a further improvement of the utility model, a reinforcing rib is provided on each side of the fixing protrusion, and the fixing through hole is located between the two reinforcing ribs. In the utility model, reinforcing ribs are provided on both sides of the fixing protrusion to improve the connection strength between the fixing protrusion and the protector body. Since the reinforcing ribs are located on both sides of the fixing protrusion, the force on the fixing protrusion as a whole is more stable and will not affect the installation of the bolts and nuts.

[0008] As a further improvement of the utility model, the reinforcing rib is perpendicular to the center line of the protector body, and the side of the reinforcing rib away from the through slot is tangent to the outer surface of the protector body. In the utility model, the two reinforcing ribs on both sides of the fixing protrusion are parallel and have fewer sharp corners.

[0009] As a further improvement of the utility model, the fixing protrusions and the reinforcing ribs on both sides of the through groove are symmetrically distributed. The symmetrical distribution of the reinforcing ribs of the utility model facilitates the manufacture of the mold of the utility model.

[0010] As a further improvement of the utility model, all the fixing protrusions and reinforcing ribs are integrally formed with the protector body, so that the overall strength of the utility model is higher and the use is safer.

[0011] In summary, the beneficial effects of the present invention are as follows: the present invention can effectively protect the electric cable, and at the same time the present invention has a good heat dissipation function, thereby improving the safety of power transmission.

[0017] like Figures 1 to 3 The cable protector shown in the figure includes a protector body 1, which can be made of materials such as rubber or plastic. The protector body 1 is used to wrap around the position of the cable line near the transmission tower or pole when in use. A through groove 2 is opened on one side of the protector body 1 along the length direction. The utility model can insert the cable into the protector body 1 from one end of the protector body 1, or the protector body 1 can be opened to both sides from the through groove 2, and the cable is placed into the protector body 1 from the through groove 2. The utility model is provided with spaced along the length direction of the through groove 2 on the protector body 1. There are more than two fixing parts 3. The utility model has at least one fixing part 3 at each end of the protector body 1. The fixing parts 3 are used to press the protector body 1 from both sides of the through slot 2 when in use. As shown in the attached drawings of the utility model, three fixing parts 3 are used to fix the protector body 1 at the through slot 2. In order to improve the heat dissipation effect of the cable, the utility model has at least one heat dissipation hole group on the protector body 1 along the circumferential direction. The cable generates heat when it is energized, and the part wrapped in the protector body 1 can be dissipated through the heat dissipation hole group, thereby improving the safety of power transmission.

When the number of heat dissipation holes in each heat dissipation hole group exceeds one, the heat dissipation holes 4 in each heat dissipation hole group are arranged at equal intervals along the length direction of the protector body 1. The number of heat dissipation holes 4 in each heat dissipation hole group in the utility model can be reasonably set according to the length of the protector body 1. When the length of the protector body 1 is large, more heat dissipation holes 4 can be opened, and when the length of the protector body 1 is small, only one heat dissipation hole 4 can be opened. The drawings of the utility model only show that each heat dissipation hole group is one heat dissipation hole 4.

[0019] like Figure 1 and Figure 4As shown, the protector body 1 in the utility model is located on both sides of the through slot 2, each of which protrudes in a direction away from the center line of the protector body 1 to form a fixing protrusion 5, and the fixing protrusions 5 on both sides of the through slot 2 are correspondingly provided with fixing through holes (not shown in the figure), wherein the surface of the fixing protrusion 5 close to the through slot 2 is coplanar with the through slot 2, and the fixing member 3 in the utility model is a bolt passing through the fixing through holes on the fixing protrusions 5 on both sides of the through slot 2 and a nut matched with the bolt, and the fixing protrusion 5 is clamped by the nut and the head of the bolt to clamp the protector body 1 on the cable.

[0020] like Figures 1 to 4 The utility model shown in the figure has a reinforcing rib 6 on each side of the fixing protrusion 5, and the fixing through hole on the fixing protrusion 5 is located between the two reinforcing ribs 6. The reinforcing rib 6 in the utility model is perpendicular to the center line of the protector body 1, and the side of the reinforcing rib 6 away from the through slot 2 is tangent to the outer surface of the protector body 1. The fixing protrusions 5 and reinforcing ribs 6 on both sides of the through slot 2 in the utility model are symmetrically distributed, and all the fixing protrusions 5 and reinforcing ribs 6 in the utility model are integrally formed with the protector body 1.
