Description

Technical Field

[0001] This invention relates to the field of de-icing technology, and more specifically to a high-voltage power line de-icing device. Background Technology

[0002] Currently, during cold seasons, especially winter, high-voltage power lines are prone to icing, which is one of the biggest destructive factors. Therefore, it is necessary to remove the ice from high-voltage lines promptly. Generally, de-icing methods for high-voltage lines fall into the following categories: First, adjusting the current and voltage in the high-voltage line to generate a higher temperature, thereby melting the ice, often resulting in significant energy waste; second, relying on manual de-icing, which is extremely dangerous, requires a high level of technical skill from operators, and the risks increase further in extreme environments. De-icing equipment for high-voltage lines, using mechanical de-icing to replace the above two traditional methods, has been disclosed in the Chinese patent database.

[0003] For example, CN110429546B discloses a high-voltage line de-icing device, which includes a movable plate. Movable slots are provided on the left and right sides of the top of the movable plate. A self-propelled motor is fixedly connected to the rear side of the movable plate and the position corresponding to the movable slot. A self-propelled rotating shaft is fixedly connected to the output shaft of the self-propelled motor. The front end of the self-propelled rotating shaft passes through the movable slot and extends into its interior. A self-propelled wheel is fixedly connected to the surface of the self-propelled rotating shaft located inside the movable slot. Vertical plates are provided on the top of the movable plate and on the front and rear sides of the movable slot.

[0004] The invention patent disclosed above (CN110429546B) can mechanically remove ice from high-voltage lines. However, the existing technology still has a problem: when the de-icing equipment encounters ice blocks that are difficult to remove, it cannot pass through the ice blocks and therefore cannot continue to remove ice blocks from other parts of the high-voltage line. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a high-voltage line de-icing device that solves the problem that existing de-icing equipment cannot overcome when encountering ice blocks that are difficult to remove.

[0006] This invention discloses a high-voltage line de-icing device, comprising a support body, wherein the support body includes a left clamp and a right clamp, the left clamp and the right clamp are connected, and a gap space is formed between the left clamp and the right clamp for passing through the high-voltage line; at least two sets of clamping and moving components are connected to the support body, each clamping and moving component is used to clamp the high-voltage line; an ice-breaking component is connected to one side of the support body, the ice-breaking component is used to hammer and clean the ice layer on the high-voltage line.

[0007] Furthermore, the right or left clamp includes a first U-shaped groove and a second U-shaped groove, which are slidably connected by a sliding member.

[0008] Furthermore, the sliding component is provided with a sliding groove, and the slide rail is provided with a long strip protrusion, which is slidably connected to the sliding groove.

[0009] Furthermore, a drive assembly is also connected to the support body. The drive assembly is connected between the first U-shaped groove and the second U-shaped groove of the left clamp or between the first U-shaped groove and the second U-shaped groove of the right clamp. The drive assembly is used to drive the corresponding first U-shaped groove and the second U-shaped groove away from or close to each other.

[0010] Furthermore, the drive assembly includes a fixing member, which has a telescopic mechanism inside. The fixing member is connected to a corresponding second U-shaped groove fixing bolt. A positioning member is fixedly connected to the corresponding first U-shaped groove, and the positioning member is connected to the output shaft of the electric telescopic cylinder.

[0011] Furthermore, the clamping and moving assembly includes a single-wheel assembly and a double-wheel assembly. The single-wheel assembly includes a concave roller, which is rotatably connected to the support body and is driven by a first motor connected to the support body. The double-wheel assembly includes an electric telescopic rod, which is connected to the support body, and a push-pull body is connected to the output shaft of the electric telescopic rod. Smooth rollers are hinged to both sides of the push-pull body via clamps, and the other end of the clamps is hinged to the support body. The single concave roller and the two smooth rollers of the double-wheel assembly are used together to clamp the high-voltage line.

[0012] Furthermore, the ice-breaking assembly includes a limiting seat connected to the support body. The tip of the ice-breaking hammer is positioned outside the limiting seat and opposite to the high-voltage line, while the tail end of the ice-breaking hammer is slidably connected to the limiting seat. A rotating body is rotatably connected to the limiting seat, and one end of the rotating body is connected to the output shaft of a servo motor mounted on the support body. A flange is formed on the tail end of the ice-breaking hammer, and a spiraling irregular groove is formed on the rotating body, which is slidably fitted with the flange. When the rotating body and the irregular groove rotate, the rotating irregular groove and the limiting seat are used to limit the ice-breaking hammer and the flange from moving away from or towards the ice layer on the high-voltage line.

[0013] Furthermore, the ice-breaking assembly also includes a cleaning mechanism connected to the side of the ice-breaking hammer on the support body. The cleaning mechanism includes a shaft tube, one side of which is rotatably connected to the support body. The shaft tube is concentrically connected to the output shaft of the second motor. The second motor is fixedly connected to the support body, and a brush unit is installed on the shaft tube.

[0014] The beneficial effects of this invention are as follows: This invention, by combining a high-voltage line de-icing device, allows the device to smoothly overcome hard ice layers when encountering them, relying on the cooperation of two sets of clamping and moving components, and continue de-icing and cleaning other parts of the high-voltage line without delaying the de-icing work, thus improving work efficiency to a certain extent.

[0031] This embodiment provides a high-voltage line de-icing device, which includes a support body, as shown in the reference. Figure 1 The diagram shows the overall structure of the support. As can be seen, the support consists of a left clamp and a right clamp. The top and bottom of both the left and right clamps are connected by two long bolts 1, and a gap is formed between the left and right clamps. This gap is used to mount the high-voltage line. Figure 2The diagram shows a three-dimensional structural representation of the left clamp. The right clamp has the same structure and function as the left clamp, which will not be described in detail here. The left clamp includes a first U-shaped groove 2 and a second U-shaped groove 3, which are arranged side by side. A sliding member 4 connects the upper and lower edges of the first U-shaped groove 2 and the second U-shaped groove 3. The left end of the sliding member 4 is fixedly connected to the first U-shaped groove 2, and the right end of the sliding member 4 is slidably connected to the slide rail on the second U-shaped groove 3. For further details, please refer to [reference needed]. Figure 3 The schematic diagram of the assembly structure of the slider 4 and the slide rail is shown in the figure. Sliding grooves 5 are formed on both sides of the slider 4, and elongated protrusions 6 are formed on both inner side walls of the slide rail. The elongated protrusions 6 are slidably connected to the sliding grooves 5 on the adjacent side. The slider 4 and the slide rail can ensure that the first U-shaped groove 2 and the second U-shaped groove 3 can be adjusted for extension and retraction.

[0032] As an optimized solution for the support structure, a drive component is connected to the support structure. For details, please refer to... Figure 4 The diagram shows the installation of the drive assembly. As can be seen from the diagram, the drive assembly is connected between the first U-shaped groove 2 and the second U-shaped groove 3 of the left clamp. The specific structure of the drive assembly is as follows.

[0033] The drive assembly includes a fixing member 7, within which is housed an electric telescopic cylinder 8 (existing technology, not described in detail here, or other telescopic mechanisms replacing the electric telescopic cylinder 8). The fixing member 7 is bolted to the second U-shaped groove 3 of the left clamp. A positioning member 9 is bolted to the first U-shaped groove 2 of the left clamp, and the positioning member 9 is connected to the output shaft of the electric telescopic cylinder 8. In use, the electric telescopic cylinder 8 is activated. Under the pushing action of the electric telescopic cylinder 8 and the limiting action of the sliding member 4 and the slide rail, the first U-shaped groove 2 and the second U-shaped groove 3 move closer or further apart.

[0034] To ensure the support structure can move smoothly on the high-voltage line, reference is made. Figure 5 The schematic diagram of the clamping and moving assembly installation structure shown in the figure illustrates that two sets of clamping and moving assemblies are connected to the front and rear sides of the support body, respectively. Each clamping and moving assembly comprises a single-wheel assembly and a double-wheel assembly, and is combined with… Figure 6 The schematic diagram of the three-dimensional structure of the clamping and moving assembly shown in the figure includes a single wheel assembly comprising a concave roller 10, which is rotatably connected to the inner wall of the left clamp via a carrier. A first motor 11 is connected to the outer wall of the left clamp via an L-plate 12. The output shaft of the first motor 11 is connected to the central shaft of the concave roller 10 via a transmission belt. To protect the first motor 11 from external damage, a protective cover 13 is installed on the outer side of the first motor 11 and on the left clamp. (Continuing with the previous section...) Figure 6The dual-wheel assembly includes an electric telescopic rod 14 (using existing technology), which is fixedly connected to the outer wall of the right clamp. A push-pull body 15 is connected to the output shaft of the electric telescopic rod 14. Smooth rollers 16 are respectively provided on the upper and lower sides of the push-pull body 15. The smooth rollers 16 are rotatably connected to a clamp 17. One end of the clamp 17 is connected to a first hinge 18, which is rotatably connected to the nearest end of the push-pull body 15. The other end of the clamp 17 is movably connected to the adjacent wall of the right clamp via a second hinge 19. The single concave roller 10 of the single-wheel assembly and the two smooth rollers 16 of the dual-wheel assembly together form a channel structure for clamping high-voltage lines.

[0035] The working principle of the two sets of clamping and moving components is as follows: First, when the high-voltage line de-icing device encounters a hard layer of ice that cannot be removed, refer to... Figure 7 The diagram showing the usage status of the two sets of clamping and moving components illustrates how the electric telescopic rod 14 at the front is activated. The electric telescopic rod 14 drives the push-pull body 15 to move along direction a1. As the push-pull body 15 moves, it causes the smooth rollers 16 to deflect along direction b1 until the two smooth rollers 16 at the front disengage from the high-voltage line. Then, the first motor 11 drives the concave roller 10 at the rear to rotate. The rotation of the concave roller 10, together with the two smooth rollers 16 at the rear, causes the high-voltage line de-icing device to continue moving along the high-voltage line. Finally, refer to... Figure 7 After the front clamping moving component passes the obstacle, the electric telescopic rod 14 pushes the push-pull body 15 back along the a2 direction until the two smooth rollers 16 in front are reset and in contact with the high-voltage line. At this time, the electric telescopic rod 14 in the rear is started in the same way, and the corresponding push-pull body 15 is moved along the a1 direction by the electric telescopic rod 14 in the rear until the two smooth rollers 16 in the rear are separated from the high-voltage line. The first motor 11 is started and drives the concave roller 10 to continue moving. The high-voltage line de-icing device successfully passes over the hard ice layer.

[0036] In order to remove the ice layer, the high-voltage line de-icing device of the present invention also includes an ice-breaking component, as shown in the reference. Figure 8 The diagram shows the installation structure of the ice-breaking components. As can be seen from the diagram, four ice-breaking components are installed at intervals on the front side of the support. The specific structure of the ice-breaking components is as follows.

[0037] refer to Figure 8 and combined Figure 9 ,in, Figure 9The diagram shows a three-dimensional structural schematic of the ice-breaking assembly. As can be seen from the two figures above, the ice-breaking assembly includes a limiting seat 20, which is connected to the support body. The tip of the ice-breaking hammer 21 is positioned outside the limiting seat 20 and opposite to the high-voltage line. The tail end of the ice-breaking hammer 21 is slidably connected to the limiting seat 20. A rotating body 22 is rotatably connected to the limiting seat 20, and one end of the rotating body 22 is connected to the output shaft of a servo motor 23 mounted on the support body. A flange 24 is formed on the tail end of the ice-breaking hammer 21, such as... Figure 10 As shown in A and B ( Figure 10 This is a schematic diagram of the external structure of the rotating body 22 (where A and B are two perspectives of the rotating body 22). A spiraling irregularly shaped groove 25 is formed on the rotating body 22, which slides into the flange 24. Simultaneously, it limits the movement of the ice-breaking hammer 21 and the flange 24 when the rotating body 22 and the irregularly shaped groove 25 rotate (in the c1 or c2 direction). In use, the servo motor 23 drives the rotating body 22 to rotate in both directions, indirectly causing the ice-breaking hammer 21 to move closer to or away from the high-voltage line, thus hammering the ice layer.

[0038] As an optimization of the ice-breaking component, after the ice-breaking hammer 21 strikes the ice layer, the blocky ice layer falls off the high-voltage line. However, a small amount of powdery ice layer remains on the high-voltage line. Therefore, this invention further designs a cleaning mechanism, referring to... Figure 11 The schematic diagram of the cleaning mechanism installation structure shown in the figure shows that the cleaning mechanism is connected to the side of the icebreaker 21 and the support body. The specific structure of the cleaning mechanism is as follows.

[0039] Specifically, the cleaning mechanism includes a shaft tube 26, one side of which is rotatably connected to the support body. The shaft tube 26 is concentrically connected to the output shaft of the second motor 27, which is fixedly connected to the support body. A brush unit is installed on the shaft tube 26, and the more specific structure of the brush unit is as follows.

[0040] refer to Figure 12The diagram shows an exploded view of the brush unit and shaft tube 26. As can be seen, the brush unit includes a brush handle shaft 28 with a circular array of bristles 29. The brush handle shaft 28 is rotatably adapted to the shaft tube 26. The shaft tube 26 has a circular array of pores 30, each corresponding to a bristle 29. The free end of the brush handle shaft 28 is connected to the output shaft of a rotary motor 31, forming a linkage. The rotary motor 31 is installed inside a circular shell 32, and the opening of the circular shell 32 is connected to the outlet of the shaft tube 26 via bolts. The advantage of this brush unit is that it can not only clean powdery ice layers but also adjust the length of the bristles 29 exposed on the outside of the shaft tube 26 according to different usage scenarios. Specifically, when adjusting the length of the bristles 29 exposed on the outside of the shaft tube 26, the rotary motor 31 drives the brush handle shaft 28 to rotate, thereby causing the bristles 29 to enter or exit the pores 30.

[0041] As an optimized solution for the brush unit, the brush unit is rotatably connected to the support body, and the support body is also connected to a positioning disk 33 for mating and fitting with the round shell 32.
