Description

Technical Field

[0001] This invention relates to the field of cable snow removal, and more specifically to a cable snow removal device. Background Technology

[0002] During winter's low temperatures and snowfall, snow or ice easily accumulates on the surface of various overhead cables. This snow accumulation not only increases the overall weight of the cables but also easily freezes into ice in low temperatures, leading to cable breakage, tower collapse, and seriously threatening the safe and stable operation of infrastructure.

[0003] Currently, snow removal operations on overhead cables still rely primarily on manual labor, which is inefficient, labor-intensive, and poses significant safety risks associated with working at heights. Existing mechanical snow removal devices generally suffer from complex structures, poor transmission stability, and compatibility only with single-specification components, resulting in limited versatility. Therefore, developing a compact, stable, and widely adaptable overhead cable snow removal device has become a critical technical challenge urgently needing to be addressed in current engineering applications. Summary of the Invention

[0004] To overcome the aforementioned shortcomings of the existing technology, the present invention aims to provide a cable snow removal device. This device has a compact structure and is easy to install. It employs multi-motor synchronous drive and helical gear meshing transmission, causing the snow removal blades to rotate around the cable. This, combined with the device's movement along the cable, achieves 360° all-around snow removal, eliminating the need for manual high-altitude operations. Its smooth transmission and thorough snow removal effectively ensure the safe operation of cables in winter.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a cable snow removal device, including a snow removal actuator; the snow removal actuator includes a motor, a motor, a motor, a helical gear, a helical gear, a housing, and snow removal blades; the motors are arranged in a ring array around the outer periphery of the cable to be snow removed; the motors are respectively connected to the helical gears; the housing is a hollow rotating body structure, and its inner wall is provided with an internal meshing gear ring, and the helical gears are all meshed with the internal meshing gear ring; the snow removal blades are fixedly installed in a ring array at the axial end of the housing, and the cable to be snow removed passes coaxially through the hollow cavity of the housing.

[0007] Preferably, the specifications and parameters of motor one, motor two, and motor three are the same, and the three sets of motors drive synchronously, driving helical gear one, helical gear two, and helical gear three to rotate synchronously, so that the circumferential force of the housing is uniform and the rotation is smooth and without jamming.

[0008] Preferably, the helical gears 1, 2, and 3 have the same module and number of teeth. The three sets of helical gears are arranged in an equilateral triangle array around the outer periphery of the cable and are stably meshed with the inner meshing gear ring on the inner wall of the housing. The multi-point meshing method improves the transmission stability and avoids problems such as slippage and uneven force that are easy to occur in single gear transmission.

[0009] Preferably, the number of snow removal blades is six, and the six snow removal blades are fixed to the end face of the housing in an equidistant circular array, with the cutting edges of the snow removal blades facing the outer peripheral surface of the cable; the circular arrangement of multiple sets of blades can achieve 360° snow removal without dead angles around the outer periphery of the cable, ensuring thorough snow removal.

[0010] Preferably, the housing is a conical hollow housing with an internal meshing gear ring located on the inner wall of the large-diameter end of the housing, and the snow removal blade is fixedly installed at the small-diameter end of the housing; the conical structure can accommodate cables of different outer diameters, while reducing the working range of the blade end and improving the snow removal accuracy.

[0011] Preferably, the inner diameter of the hollow cavity of the housing is larger than the outer diameter of the cable, and the distance between the cutting edge of the snow removal blade and the outer peripheral surface of the cable is adjustable, which can be flexibly adjusted according to the snow thickness on the cable, so as to ensure the snow removal effect while avoiding the blade from scratching the outer sheath of the cable.

[0012] The technical effects and advantages of this invention are as follows:

[0013] (1) The present invention adopts three sets of motors in a ring array for synchronous drive, and three sets of helical gears mesh with the internal gear ring of the housing at multiple points for transmission. The transmission process is uniform and stable, effectively avoiding the slippage and jamming problems that are easy to occur in single drive structures, and ensuring the stability of the device during high-altitude cable operations.

[0014] (2) The present invention drives the snow removal blades of the end ring array to rotate synchronously through the shell, which can realize 360° full coverage snow removal operation on the outer periphery of the cable. The snow removal can be completed along the cable while the device is moving along the cable. The snow removal efficiency is high and the cleaning is thorough. There is no need for manual high-altitude operation, which greatly reduces the safety risks of operation and maintenance.

[0015] (3) The device has a compact overall structure and adopts a hollow wire-threading structure, which is convenient to install and adaptable to overhead cables of different outer diameters; the distance between the blade and the cable surface is adjustable, taking into account both snow removal effect and cable protection, and avoiding scratching the cable outer sheath.

[0016] This device can not only quickly clear snow from the surface of cables, but also handle lightly icy snow layers. It has a wide range of applications and effectively solves the safety hazards of snow accumulation on cables in winter, ensuring the stable operation of the power system. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only and are not intended to be exhaustive or limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the invention, enabling those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0023] Example 1

[0024] like Figures 1-3As shown in the figure, the cable snow removal device disclosed in this embodiment includes a snow removal actuator 200; the snow removal actuator 200 includes a first motor 201, a second motor 203, a third motor 205, a first helical gear 202, a second helical gear 204, a third helical gear 206, a housing 207, and a snow removal blade 209; the first motor 201, the second motor 203, and the third motor 205 have the same specifications and are distributed in an equilateral triangular array on the outer periphery of the cable 1 to be snow removed; the first motor 201, the second motor 203, and the third motor 205 The output ends are respectively connected to helical gear 1 202, helical gear 204, and helical gear 3 206; the three sets of helical gears have the same module and number of teeth, and are distributed in an equilateral triangular array around the outer periphery of the cable 1; the housing 207 is a conical hollow rotating body structure, and its large-diameter end inner wall is provided with an internal meshing gear ring 208, which meshes with the helical gear 1 202, helical gear 204, and helical gear 3 206; the inner cavity of the housing 207 is axially connected, and the snow removal cable 1 is coaxially inserted into the housing 207, and the inner diameter of the housing 207 is larger than the outer diameter of the cable 1; the snow removal blades 209 are fixed in an equidistant annular array at the small-diameter end of the housing 207, with the cutting edge facing the outer peripheral surface of the cable 1, and the distance between the cutting edge and the surface of the cable 1 is adjustable.

[0025] The working principle of this embodiment is as follows: In use, the snow removal actuator 200 is fitted onto the outside of the cable 1, so that the cable 1 coaxially passes through the inner cavity of the housing 207. The distance between the cutting edge of the snow removal blade 209 and the surface of the cable 1 is adjusted to match the snow thickness of the cable 1. The motors 201, 203, and 205 are started, and the three motors drive synchronously, respectively driving the helical gears 202, 204, and 206 to rotate synchronously. The three helical gears mesh with the internal meshing gear ring 208 on the inner wall of the housing 207, causing the housing 207 to rotate around the cable 1. The housing 207 drives the snow removal blade 209 to rotate synchronously. As the device moves along the cable 1, the snow removal blade 209 cleans the snow on the surface of the cable 1, completing the snow removal operation.

[0026] Example 2

[0027] like Figure 4 As shown, the only difference between this embodiment and Embodiment 1 is the number of snow removal blades.

[0028] The snow removal actuator 200 includes four snow removal blades 209. The four snow removal blades are fixed in an equidistant ring array at the small diameter end of the housing 207, with the cutting edges facing the outer peripheral surface of the cable 1. The rest of the structure is the same as in Embodiment 1.

[0029] Structural analysis reveals the following: Example 1 uses six blades, spaced approximately 60° apart. Upon complete rotation, the blade coverage area seamlessly connects, achieving 360° full coverage of the cable circumference and ensuring no blind spots. Example 2 uses four blades, spaced 90° apart. Based on the principle of geometric coverage, the 90° interval creates physical gaps in the circumferential direction that are not covered by the blades. As the device moves along the cable, these gaps cannot be effectively cut, posing a risk of snow leakage.

[0030] Therefore, the design with six blades has a greater advantage in terms of coverage and is the preferred solution of this invention.

[0031] Obviously, the above descriptions are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in the present invention are implemented using conventional means in the art unless otherwise specified or limited.
