Description

Technical Field

[0001] The utility model relates to the technical field of overhead insulated conductors, in particular to an externally installed insulated medium and low voltage overhead insulated conductor. Background Art

[0002] Overhead cable (full name overhead insulated cable) is an overhead conductor equipped with an insulation layer and a protective sheath. It is a special cable manufactured using a production process similar to that of cross-linked cables. It is a new way of transmitting electricity between overhead conductors and underground cables. Low-voltage conductors refer to conductive components in AC power systems or DC systems below 0.6kV (including 0.6kV) and are used to transmit electrical energy.

[0003] In order to prevent the insulation layer from spontaneously combusting due to its own aging and being in a high-temperature state, an anti-aging and durable medium and low voltage overhead line is developed (see patent number: 202023062511.6 for details), including a conductor and an insulation layer sleeved on the conductor. A flame-retardant tube is provided on the periphery of the insulation layer, and the flame-retardant tube is sleeved on the insulation layer. A barrier film is fixed on the inner wall of the flame-retardant tube, and an inert gas is filled between the barrier film and the inner wall of the flame-retardant tube. A clamp is tied to the outer wall of the flame-retardant tube, and an indicator light is installed on the clamp. The indicator light is coupled with a pressure loss alarm circuit for controlling the on and off of the indicator light. When the clamp is not tightly against the flame-retardant tube, the indicator light emits a bright warning signal.

[0004] However, if the existing medium and low voltage overhead insulated wires are in a poor straightening state during use, they will be affected by wind and sway randomly. If this continues for a long time, the butt ends of the wires will become loose, making it impossible to adjust the straightening state, resulting in poor use effect and reduced utilization rate. Utility Model Content

[0005] The purpose of the utility model is to provide an externally mounted insulated medium and low voltage overhead insulated conductor to solve the problem that, during use, if the existing medium and low voltage overhead insulated conductor is in a poor straight state, it will be affected by wind and sway at will. If this continues for a long time, the butt end of the conductor will become loose, making it impossible to adjust the straight state, resulting in poor use effect and reduced utilization rate.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an externally mounted insulated medium and low voltage overhead insulated conductor, comprising:

[0007] Conductors, used to transmit electrical energy;

[0008] The sleeve assembly is used to wrap the wire and provide pressure support;

[0009] a telescopic assembly located on one side of the sleeve assembly and extending to one side of the interior of the sleeve assembly;

[0010] The sleeve assembly includes a sleeve, a first pressure plate is provided on one side of the sleeve, a first slot is provided at the bottom of the first pressure plate, the telescopic assembly includes a sleeve rod, a second pressure plate is provided on the side of the sleeve rod away from the sleeve, a second slot is provided on the top of the second pressure plate, a limiting plate is provided on the other side of the sleeve rod, and an elastic member is provided on the outside of the sleeve rod.

[0011] As a further solution of the present invention: the other side of the sleeve rod extends to one side of the interior of the sleeve, and the elastic member is located outside the sleeve rod and inside the sleeve.

[0012] As a further solution of the present invention: a movable hole is provided on one side of the sleeve, and the inner diameter of the movable hole is smaller than the outer diameter of the limiting plate and larger than the outer diameter of the sleeve rod.

[0013] As a further solution of the present invention: the inner sections of the limiting plate and the sleeve are both square structures.

[0014] As a further solution of the present invention: the sleeve rod is movably connected to the sleeve through a movable hole.

[0015] As a further solution of the present invention: a damping pad is provided on the outer side of the limiting plate, and the damping pad is located on the end surface of the limiting plate adjacent to the inner wall of the sleeve.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] When the wire is loosened, the total length of the sleeve and the sleeve rod can be shortened under the action of the elastic member, so that the wire can be automatically straightened, thereby ensuring that it is always in a straight state, thereby avoiding the loosening of the butt end of the wire under the action of wind, and thus the straight state can be adjusted automatically, so that the use effect is better and the utilization rate is improved.

[0024] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, an externally installed insulating medium and low voltage overhead insulating wire includes:

[0025] Conductor 3, used for transmitting electric energy;

[0026] Socketing component 1, used for winding and pressing and supporting the conductor 3;

[0027] The telescopic component 2 is located on one side of the socket component 1 and extends to one side inside the socket component 1.

[0028] The socket component 1 includes a sleeve 101. A first pressing plate 102 is provided on one side of the sleeve 101. A first card slot 1031 is provided at the bottom of the first pressing plate 102. The telescopic component 2 includes a sleeve rod 201. A second pressing plate 202 is provided on the side of the sleeve rod 201 away from the sleeve 101. A second card slot 203 is provided at the top of the second pressing plate 202. A limiting plate 205 is provided on the other side of the sleeve rod 201. An elastic member 204 is provided on the outer side of the sleeve rod 201.

[0029] Please refer specifically to Figure 1 、 2 and 3. The other side of the sleeve rod 201 extends to one side inside the sleeve 101. The elastic member 204 is located on the outer side of the sleeve rod 201 and inside the sleeve 101.

[0030] Please refer specifically to Figure 1 、 2 and 3. An activity hole is provided on one side of the sleeve 101. The inner diameter of the activity hole is smaller than the outer diameter of the limiting plate 205 and larger than the outer diameter of the sleeve rod 201, thereby preventing the sleeve rod 201 from falling off during movement and improving stability.

[0031] Please refer specifically to Figure 3 , both the inner cut surfaces of the limiting plate 205 and the sleeve 101 are square structures. By using the limiting plate 205 and the sleeve 101 with square inner cut surfaces, the sleeve rod 201 can be forced to translate along the sleeve 101 without rotating, thereby improving the pressing stability against the wire 3.

[0032] Please refer specifically to Figure 1 、 2 and 3. The sleeve rod 201 is movably connected to the sleeve 101 through the activity hole.

[0033] Please refer specifically to Figure 3 , a damping pad is provided on the outer side of the limiting plate 205, and the damping pad is located at the end face adjacent to the inner wall of the sleeve 101 of the limiting plate 205.

[0034] The working principle of the present invention is as follows: when in use, one end of the wire 3 is inserted into the first pressure plate 102 through the first card slot 103, and then the wire 3 is spirally wound to the outside of the sleeve 101, and the sleeve rod 201 is pulled outward laterally, so that the sleeve rod 201 moves to the left and carries the limit plate 205 to move to the left along the inside of the sleeve 101 and generates a pressure on the elastic member 204 inside the sleeve 101, causing it to deform under force and generate corresponding elastic potential energy, while the wire 3 is continuously wound around the outside of the sleeve rod 201 and inserted into the second card slot 203 on the second pressure plate 202. On the other side, the pulling force on the sleeve rod 201 to the left is then released, so that it can be reset under the action of the rebound force of the elastic member 204 and press the wire 3 wrapped around the sleeve 101 and the outside of the sleeve rod 201. When the wire 3 is relaxed, the total length of the sleeve 101 and the sleeve rod 201 can be shortened under the action of the elastic member 204, so that the wire 3 can be automatically straightened, thereby ensuring that it is always in a straight state, thereby avoiding the loosening of the butt end of the wire under the action of wind, and thus the straight state can be adjusted automatically, making its use effect better and improving the utilization rate.

[0035] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the scope of protection of the present invention.
