Description

Technical Field

[0001] The utility model relates to the technical field of power maintenance equipment, in particular to an overhead wire de-icing and snow-removing device. Background Technique

[0002] In northern China, every winter, there will be heavy snowfall. If this snow falls on the overhead wires and is not cleared in time, it may break the overhead wires, causing a large-scale power outage and bringing great economic losses. At the same time, the melting and condensation of this rain and snow into ice will also increase the load-bearing burden of the overhead wires. However, due to the high position of the high-voltage overhead wires, it is inconvenient to clean the snow. The snow and ice are removed by manual cleaning and knocking methods. However, due to the harsh ice and snow environment and the fact that the overhead wires are often erected very high, not only the work efficiency cannot be guaranteed, but also the safety of the staff is difficult to ensure.

[0003] In order to solve the above problems, this case came into being. Content of the Utility Model

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model is realized through the following technical solutions: An overhead wire de-icing and snow-removing device includes a support disk. A plurality of connecting pieces are axially arranged on the support disk. The outer ends of the connecting pieces are provided with wire-binding seats sleeved outside the overhead wires. A hook groove is provided on the lower side of the support disk, and a hook can be connected in the hook groove and an insulating extension cord can be connected downward.

[0008] Preferably, the support disk is provided with an arc-shaped through groove at the position of the connecting piece, and a T-shaped slider is arranged at the rear side of the connecting piece.

[0009] Preferably, the connecting piece includes two spaced-apart support blocks one and support blocks two. The support blocks one and support blocks two are connected by a pulling block. Convex grooves are respectively opened on the relative inner sides of the support blocks one and support blocks two, and convex moving blocks are respectively connected to both sides of the pulling block. There is a surplus gap between the convex moving blocks located in the convex grooves.

[0010] Preferably, the connecting piece includes two spaced-apart support blocks one and support blocks two. A pull rod is arranged between the support blocks one and support blocks two. The pull rod is placed in the concave holes opened on the inner sides of the support blocks one and support blocks two. The two support blocks are connected by a spring, and the spring is sleeved outside the pull rod.

[0012] After adopting the above technical solution, compared with the prior art, the utility model has the following advantages: The overhead wire de-icing and snow-removing device of the utility model can sweep the snow covering outside the overhead wire at one time and quickly by pulling from the lower side. Secondly, the radial direction of the wire bundling seat is designed to be length adaptively adjustable and is configured to be circumferentially movable, so that the wire bundling seat has a certain deformation surplus to adapt to multiple overhead wires laid in a long distance and sagging.

[0018] The present utility model will be further elaborated in detail below with reference to the drawings and embodiments.

[0019] As Figure 1 shown: An overhead wire de-icing and snow-removing device includes a support disc 2. A plurality of connecting pieces 3 are axially arranged on the support disc 2. The outer ends of the connecting pieces 3 are provided with a wire bundling seat sleeved outside the overhead wire 1. A hook groove 8 is provided on the lower side of the support disc 2. A hook can be connected in the hook groove 8 and an insulating extension cord can be connected downward. By pulling from the lower side, the snow covering outside the overhead wire 1 can be swept away at one time and quickly.

[0020] However, the overhead wire 1 between long-distance utility poles is prone to sagging problems, resulting in the need to additionally radially recover the overhead wire 1 (lift it when passing through the sagging position) during the movement of the de-icing and snow-removing device, that is, when sweeping past. Moreover, the sagging positions and directions of multiple overhead wires 1 are different, so that a greater additional force is required when the de-icing and snow-removing device passes through.

[0021] Therefore, the wire bundling seat 4 needs to have a certain deformation surplus to adapt to multiple overhead wires 1 laid in a long distance. This solution mainly designs the radial direction of the wire bundling seat 4 to be length adaptively adjustable and is configured to be circumferentially movable to address the above problems.

[0022] See the appendix Figure 2 As shown. Specifically, the support plate 2 is provided with an arc-shaped through groove 5 at the connecting member 3. A T-shaped slider 6 is provided at the rear side of the connecting member 3, so that the connecting member 3 can rotate axially along the support plate 2 to adjust its position under the action of an external force. A clamping post 7 is provided at the front side of the connecting member 3 to restrict the T-shaped slider 6 on the connecting member 3, and a slight gap is left between the T-shaped slider 6 and the support plate 2 for movement.

[0023] Secondly, the connecting member 3 is set to be adjustable in length. See the appendix Figure 3 As shown, the connecting member 3 includes two spaced-apart first support blocks 31 and second support blocks 32, which are connected by a pull block 33. Convex grooves 35 are respectively formed on the relative inner sides of the first support block 31 and the second support block 32, and convex moving blocks 34 are respectively connected to both sides of the pull block 33. There is a surplus gap between the convex moving blocks 34 located in the convex grooves 35, so that the first support block 31 and the second support block 32 can move relatively in the radial direction to adjust their positions.

[0024] Furthermore, considering that the above-mentioned connecting member 3 cannot be reset without an external force and has a slow force response speed, therefore, as shown in the appendix Figure 4 As shown, the pull block 33 is set as a pull rod 37. The pull rod 37 is placed in the concave holes formed on the inner sides of the first support block 31 and the second support block 32. The two support blocks are connected by a spring 36, and the spring 36 is sleeved outside the pull rod 37.

[0025] The above is based on the embodiments as inspiration. Through the above description, relevant staff can completely make various changes and modifications without departing from the idea of this invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
