Description

Technical Field

[0001] This utility model relates to the field of field cable maintenance technology, and in particular to a field cable self-snow removal device. Background Technology

[0002] In recent years, extreme weather events such as heavy rain and snow have become more frequent. Power transmission cables in the field are often damaged or even broken due to the accumulation of ice and snow and the excessive tension they bear, causing inconvenience and losses to society.

[0003] The accumulation of ice and snow on cables begins with the adhesion of snowflakes. Due to temperature changes, the snowflakes on the cable surface melt and freeze. As more and more snowflakes adhere, thick layers of snow or even icicles accumulate, affecting the cable's lifespan. In recent years, freezing rain has frequently occurred in the Jiangnan region. Snowflakes falling on cables freeze quickly, accelerating the formation of icicles and causing large icicles to form rapidly, damaging the cables.

[0004] Analysis of the formation of cable icicles reveals that if the speed at which snowflakes falling onto the cable fall to the ground is less than the speed at which the snowflakes on the cable melt and condense, the icicles will gradually grow larger; conversely, if the falling speed of snowflakes on the cable can be increased, large icicles will not form. Summary of the Invention

[0005] This disclosure provides a self-snow removal device for power cables in the field. When snowfall occurs in the field, the device uses wind force and snow accumulation to continuously apply a twisting angle to the cable, enabling the cable to autonomously remove the snow that falls and accumulates on the power transmission cable, thereby reducing the accumulation of ice and snow on the cable.

[0006] The device mainly includes: a base, short connecting rods, long connecting rods, a load-bearing component, and snow-collecting parts; among which:

[0007] The substrate is used to be fitted onto the cable and kept relatively fixed to the cable;

[0008] The short connecting rod and the long connecting rod extend outward from the side wall of the base surrounding the cable, and the short connecting rod and the long connecting rod are located on both sides of the cable respectively;

[0009] The long connecting rod connects to the snow accumulation component, and the upper surface of the snow accumulation component is flat to receive falling snow.

[0010] The short connecting rod connects to the load and is used to balance the long connecting rod and the snow accumulation component; the outer surface of the load is spherical or nearly spherical;

[0011] After installation, the upper surfaces of the long connecting rod and its connected snow accumulation components are horizontal relative to the cable, while the short connecting rod is inclined downward relative to the cable. The short connecting rod and its connected load are balanced with the rotational torque of the long connecting rod and its connected snow accumulation components relative to the cable.

[0012] Furthermore, the main body of the substrate is a cylindrical structure with grooves on the side walls, and it is mounted and snapped onto the cable using the elasticity of the substrate material.

[0013] Furthermore, the main body of the substrate consists of two interlocking parts that are fixed to the cable.

[0014] Furthermore, the substrate also includes fastening components for securing the main body of the substrate to the cable after it is engaged.

[0015] Furthermore, the snow accumulation component adopts a planar structure.

[0016] Furthermore, a slope is provided between the central axis and the edge of the snow accumulation component, so that the thickness at the edge is less than the thickness at the central axis, and the central axis is aligned with the direction of the long connecting rod.

[0017] Furthermore, several of the aforementioned devices are arranged symmetrically and at intervals on the field cable.

[0018] The device is equipped with a snow accumulation component, which is equivalent to increasing the wind-receiving area and snow accumulation area of ​​the cable (the principle of leaves). During snowfall, the cable can be twisted continuously by the wind, causing snowflakes on the cable to fall off.

[0019] On the other hand, in situations with light or no wind and heavy snow (which is most likely to cause snow accumulation and natural disasters), the device can disrupt the balance on both sides of the cable as snow accumulates on the snow-accumulating component, causing the long connecting rod to tilt and twist the cable, helping the snowflakes on the cable to fall off. When the tilt angle becomes large enough, the snow accumulated on the snow-accumulating component will fall off as a whole, and the cable twist angle will quickly recover, which will once again shake off the snowflakes on the cable; thus, reducing the accumulation of snow on the cable.

[0020] Compared with the prior art, the beneficial effects of this disclosure are: the structural design is simple and practical, and it can effectively utilize the effect of wind or snow accumulation to drive the cable to twist in snowy weather, helping to reduce snow accumulation on the cable in the field and avoid further secondary disasters.

[0027] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0028] This disclosure provides a self-snow removal device for cables in the field. In one embodiment, the overall structure and the state after installation are shown in the attached figure. Figure 1 and 2 As shown, it mainly includes:

[0029] Base 4: It is a cylindrical structure with an opening in the middle. The base can be fitted onto the cable 1 and is fixed to the cable by the elasticity of its own material. The short rod 2 and long rod 3 extending from the side wall of the base 4 are located on both sides of the cable.

[0030] Short rod 2 connects to weight 3;

[0031] The long rod section 5 is connected to the large disc 6, which serves as a snow accumulation component.

[0032] The weight 3 is spherical or near-spherical in shape, minimizing its volume so that the accumulation speed of snowflakes during snowfall is much less than that of the large disc 6 connected to the long rod 5.

[0033] As attached Figure 2 As shown, after the device is installed on the cable, the weight 3 and the large disc 6 are in a balanced state with the base 4 and the cable 1 as the pivot, and the large disc is in a horizontal position.

[0034] Matrix 4 can also consist of two interlocking parts, as shown in the attached figure. Figure 3 As shown.

[0035] Alternatively, locking screws can be provided on the base to further secure the main body after it is installed onto the cable.

[0036] As a preferred option Figure 1 and Figure 2 In the illustrated embodiment, a ramp is provided between the central axis and the edge of the large disc, such that the thickness at the edge is less than the thickness at the central axis, and the central axis is aligned with the direction of the long connecting rod. The ramp facilitates the accumulation of snow on the large disc before it falls to the ground.

[0037] As snowflakes accumulate on the large disc during heavy snowfall, the changes in the state of the long and short rods are shown in the attached figure. Figure 4 As shown in the diagram, 1 represents a small amount of snowflakes falling, and 2 represents a large amount of snowflakes falling. As snowflakes continuously adhere to the large disc, the accumulated snowflakes increase in weight, causing the device to tilt and the twist angle on the cable gradually increases. When too many snowflakes accumulate on the large disc, resulting in a large angle, the snowflakes will slide off, and the device will return to a horizontal position. This process repeats. In this way, the cable generates increasing twist. After the snow on the large disc falls and quickly returns to its horizontal position, the snowflakes on it will continuously fall due to the twisting of the cable, thus preventing the formation of icicles.

[0038] In addition, the large disc on the long pole can be used as an auxiliary tool for clearing ice, making it easier for maintenance workers to tap and break the ice on the cable, thus simplifying the maintenance work.

[0039] As can be seen, the snow-collecting component (large disc) in this disclosure utilizes the principle of leaves to enable the cable to better utilize the power of external wind and snow to clear its own snow and reduce the damage caused by snow accumulation.

[0040] As attached Figure 5 In the illustrated implementation, several self-snow removal devices are arranged symmetrically and in a staggered manner. This arrangement helps maintain the overall torque balance of the cable under normal weather conditions.

[0041] When using the apparatus described in this disclosure, the following points should be noted:

[0042] (1) The torque of the weight and the large disk are balanced, so that the long rod and the large disk are kept in an approximately horizontal state;

[0043] (2) For cables of different diameters and hardness, match different sizes of base, long rod and large disc, as well as corresponding short rod and weight, so that the use effect of the device matches the corresponding cable.

[0044] (3) The base, connecting rod, disk, etc. of the device are made of lightweight materials to reduce the weight of the device itself.

[0045] The above technical solutions are merely exemplary embodiments of this utility model. For those skilled in the art, based on the structure and principle disclosed in this utility model, it is easy to make various types of improvements or modifications, and not limited to the structure described in the specific embodiments above. Therefore, the methods described above are only preferred and not restrictive.
