Description

Technical Field

[0001] This invention relates to the technical field of high-voltage line cleaning and maintenance, specifically to a high-voltage transmission line mounted cleaning and obstacle removal device and its cleaning method. Background Technology

[0002] Ice and snow on high-voltage power lines pose significant challenges to the safe operation of power systems, transportation, and residents' lives. Therefore, taking effective anti-icing and de-icing measures to improve the power grid's disaster resilience is a crucial task for ensuring power supply.

[0003] To address this, high-voltage line snow removal robots are typically used to clean and remove obstacles from high-voltage lines, ensuring the safe operation of the power system. Specifically, the robots are equipped with snow and ice removal blades, which rotate to clean and remove obstacles from the high-voltage lines.

[0004] However, existing high-voltage line snow removal robots are usually designed for continuous operation. Due to the harsh working environment (low temperature), the ice and snow removed from the high-voltage lines tend to accumulate on the blades. Over time, the snow and ice condenses on the blades, which negatively affects the normal operation of the blades, resulting in poor obstacle removal and even hindering the robot's movement, making it unable to continue working. Summary of the Invention

[0005] The purpose of this invention is to provide a high-voltage transmission line mounted cleaning and obstacle removal device and its cleaning method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-voltage transmission line mounted cleaning and obstacle removal device is used to remove ice and snow from two parallel high-voltage lines, which includes two sets of cleaning mechanisms installed opposite each other.

[0008] The cleaning mechanism includes a housing and two sets of auxiliary wheels mounted on the housing. The cleaning mechanism also includes:

[0009] A walking drive structure is installed on the housing and connected to multiple cleaning components distributed along the circumference via a transmission structure. The cleaning components are arc-shaped and have a conical surface on the inner side. Multiple conical needles are provided on the conical surface. The interior of the cleaning components is hollow and multiple air holes are provided on the conical surface. One-way valves are provided in the air holes. The multiple cleaning components are respectively engaged with multiple sets of air blowing structures provided on the housing.

[0010] The walking drive structure can drive multiple cleaning components to move in a circular motion around the high-voltage line through the transmission structure, so that the conical needle can perform cleaning action on the ice and snow on the high-voltage line. The transmission structure is also connected to an opening and closing drive structure that can cause the multiple cleaning components to perform expansion or closing action. When the walking drive structure stops moving and the expansion action of the multiple cleaning components is completed, the blowing structure is triggered, which can blow hot air into the cleaning components. When the multiple cleaning components remain in the closed state, they form an obstacle removal tool.

[0011] As a further aspect of the present invention: the opening and closing drive structure includes a guide assembly installed on the side of the housing and a push-pull assembly connecting the guide assembly and the plurality of cleaning components, and the guide assembly is connected to the walking drive structure through the transmission structure.

[0012] As a further embodiment of the present invention: the guide assembly includes a guide plate fixed to the side of the housing, a first arm fixed on the guide plate, and a rotating sleeve rotatably connected to the first arm. The rotating sleeve connects the transmission structure and the push-pull assembly. Multiple guide arms are fixed to the outer wall of the rotating sleeve. Each guide arm is slidably fitted with a sleeve plate. Multiple cleaning components are respectively fixed to multiple sleeve plates.

[0013] As a further embodiment of the present invention: the push-pull assembly includes a horizontal plate that is slidably fitted with the guide plate, a second arm fixedly mounted on the horizontal plate, and a kit that is rotatably connected to the second arm. The kit is slidably fitted with the rotating sleeve, and the kit is connected to multiple sleeve plates respectively through multiple connecting rods.

[0014] The two ends of the connecting rod are rotatably connected to the kit and the sleeve plate, respectively. The horizontal plate is also connected to an active drive component located inside the housing. The active drive component can cause the horizontal plate to move along the axial direction of the rotating sleeve and is connected to the air blowing structure.

[0015] As a further embodiment of the present invention: the air blowing structure includes a long box fixed inside the box, a piston plate slidably sealed inside the long box, and a push rod fixedly connected to the piston plate. The push rod is connected to the active driving assembly. A one-way valve is connected to the side of the long box on the outer wall of the box, and an air supply component is also connected to it through a conduit. When the multiple cleaning components complete the expansion action, the outer wall of the cleaning component is sealed and fitted to the inner wall of the air supply component.

[0016] The push rod passes through the fixed plate at the end of the long box and is slidably connected to the fixed plate. A cylindrical spring is sleeved on the outer periphery of the push rod, and the two ends of the cylindrical spring are respectively connected to the fixed plate and the piston plate.

[0017] As a further embodiment of the present invention: the active drive component includes two electric push rods installed in the housing and a drive arm fixedly connected to the movable ends of the two electric push rods. A protruding post is fixed on the drive arm, and a transmission plate is fixed on the cross plate.

[0018] The transmission plate is provided with a through groove that matches the protrusion. The protrusion passes through the through groove and is slidably connected to the transmission plate. The through groove includes an inclined section and a vertical section connected together.

[0019] As a further embodiment of the present invention: the drive arm is fixedly connected to a follower plate, the follower plate is provided with a groove adapted to the push rod, and the end of the push rod away from the piston plate extends into the groove and is slidably connected to the follower plate;

[0020] The trough includes a first vertical trough, a second vertical trough, a horizontal trough, a first folding trough, and a second folding trough connected together. The end of the second folding trough away from the first folding trough is connected to the first vertical trough and the second vertical trough.

[0021] The first folding groove is parallel to the first vertical groove and the second vertical groove. The second folding groove is inclined. A deflector is also rotatably mounted on the follower plate. The deflector is located at the end of the second folding groove away from the first folding groove, and the rotating shaft is connected to a torsion spring.

[0022] As a further embodiment of the present invention: the walking drive structure includes two walking wheels rotatably mounted on the housing, the rotation shafts of the two walking wheels are connected by a first belt, the rotation shaft of one of the walking wheels is connected to the output end of a drive motor mounted on the housing, and the rotation shaft of the other walking wheel is connected to the rotating sleeve through the transmission structure.

[0023] As a further embodiment of the present invention: a mounting arm is fixed to the side of the housing, and the transmission structure includes a gear set disposed on the mounting arm and a transmission shaft rotatably mounted on the housing. One end of the transmission shaft is connected to the rotating shaft of the walking wheel through a bevel gear set, and the other end is connected to the gear set through a second belt. The gear set engages with the teeth disposed on the outer wall of the rotating sleeve.

[0024] A method for cleaning high-voltage power lines, using the aforementioned cleaning and obstacle removal equipment, includes the following steps:

[0025] Step 1: Install the equipment onto the high-voltage line, ensuring that multiple cleaning components surround the high-voltage line;

[0026] Step 2: The walking drive structure is activated, driving the equipment to move along the high-voltage line. At the same time, the walking drive structure drives multiple cleaning components to make circular motions around the high-voltage line through the transmission structure, performing the removal action on the ice and snow on the high-voltage line.

[0027] Step 3: The walking drive structure stops operating, and the opening and closing drive structure drives multiple cleaning components to perform expansion actions;

[0028] Step four: After the expansion actions of multiple cleaning components are completed, the air blowing structure is triggered, blowing hot air onto the cleaning components.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This application involves setting multiple cleaning components around the high-voltage line, and these components are capable of opening and closing. When the components are in a retracted state, they can act as obstacle removal tools. During operation, the walking drive structure periodically stops operating. First, the opening and closing drive structure drives the multiple cleaning components to expand, enhancing the effect of the subsequent blowing structure in dispersing accumulated ice and snow. This achieves the self-cleaning function of the equipment, enabling it to overcome harsh working environments, ensuring normal operation, avoiding adverse effects on the equipment's work due to working environment factors, and guaranteeing the cleaning and obstacle removal effect on the high-voltage line as well as the stability of the equipment's operation.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0043] Please see Figures 1-9 In this embodiment of the invention, a high-voltage transmission line mounted cleaning and obstacle removal device is used to remove ice and snow from two parallel high-voltage lines 2, which includes two sets of cleaning mechanisms installed opposite to each other.

[0044] The cleaning mechanism includes a housing 1 and two sets of auxiliary wheels mounted on the housing 1. The cleaning mechanism also includes:

[0045] A walking drive structure is installed on the housing 1 and is connected to multiple cleaning components 14 distributed along the circumference via a transmission structure. The cleaning component 14 is arc-shaped and has a conical surface on its inner side. Multiple conical needles are provided on the conical surface. The interior of the cleaning component 14 is hollow and multiple air holes are provided on the conical surface. One-way valves are provided in the air holes. The multiple cleaning components 14 are respectively engaged with multiple sets of air blowing structures provided on the housing 1.

[0046] The walking drive structure can drive multiple cleaning components 14 to move in a circular motion around the high-voltage line 2 through the transmission structure, so that the conical needle can perform cleaning action on the ice and snow on the high-voltage line 2. The transmission structure is also connected to an opening and closing drive structure that can cause the multiple cleaning components 14 to perform expansion or closing action. When the walking drive structure stops moving and the expansion action of the multiple cleaning components 14 is completed, the blowing structure is triggered, which can blow hot air into the cleaning components 14. When the multiple cleaning components 14 are kept in the closed state, they form an obstacle removal tool.

[0047] It should also be noted that, with the attached Figure 1 For example, during cleaning, multiple cleaning components 14 are in sequential contact and form a cylindrical structure around the high-voltage line 2. However, this cylindrical structure is not closed. By controlling the number of cleaning components 14, the lower part of the cylindrical structure has an opening (see Appendix). Figure 4 Therefore, during the actual implementation, when the staff installs the equipment, it is convenient that after the installation is completed, the high-voltage line 2 can be surrounded by multiple cleaning components 14. For this purpose, the walking auxiliary wheel set includes an assembly arm 3 fixed to the housing 1 and two side wheels 4 provided on the assembly arm 3. Each of the two side wheels 4 is equipped with a movable block (not labeled in the figure) that is slidably provided on the assembly arm 3. The movable block is fastened to the assembly arm 3 by bolts. By adjusting the position of the two movable blocks, the two side wheels 4 can clamp the high-voltage line 2, thereby stabilizing the movement of the equipment. Finally, the two housings 1 can be fixed to improve the overall stability of the equipment.

[0048] When in operation, the walking drive structure works, and the entire device moves along the high-voltage line 2. At the same time, the walking drive structure can drive multiple cleaning parts 14 to make circular motion around the high-voltage line 2 through the transmission structure. Then, the conical needles on the inner conical surface of the cleaning parts 14 can effectively remove ice and snow from the high-voltage line 2.

[0049] During the entire operation, the walking drive structure will stop periodically. At this time, the opening and closing drive structure drives multiple cleaning components 14 to perform an expansion action. Then, the blowing structure blows air into the cleaning components 14, which has the effect of blowing away the ice and snow accumulated on the inner wall of the cleaning components 14. As the working time increases, ice and snow easily accumulate on the inner wall of multiple cleaning components 14. Due to the low working temperature of the equipment, this ice and snow will quickly freeze into ice. At this time, it will affect the removal effect of the conical needle on the ice and snow on the high voltage line 2, and may even obstruct the movement of the equipment on the high voltage line 2, thereby causing the walking drive structure to malfunction.

[0050] Therefore, in this application, multiple movable cleaning components 14 are provided. During the entire working process, the walking drive structure stops operating periodically. First, the opening and closing drive structure drives the multiple cleaning components 14 to expand, which enhances the effect of the subsequent blowing structure in blowing away the accumulated ice and snow, realizing the self-cleaning function of the equipment. This enables the equipment to overcome the harsh working environment on its own, ensure normal operation, and avoid adverse effects on the operation of the equipment due to working environment factors.

[0051] Please refer to it again. Figure 1 , Figure 6 , Figure 7 as well as Figure 8 The opening and closing drive structure includes a guide assembly installed on the side of the housing 1 and a push-pull assembly connecting the guide assembly and a plurality of cleaning components 14. The guide assembly is connected to the walking drive structure through the transmission structure. The guide assembly includes a guide plate 7 fixed to the side of the housing 1, a first support arm 701 fixed on the guide plate 7, and a rotating sleeve 9 rotatably connected to the first support arm 701. The rotating sleeve 9 connects the transmission structure and the push-pull assembly. A plurality of guide arms 11 are fixed to the outer wall of the rotating sleeve 9. Each guide arm 11 is slidably fitted with a sleeve plate 12. A plurality of cleaning components 14 are respectively fixed to a plurality of sleeve plates 12. The push-pull assembly includes a horizontal plate 8 slidably fitted with the guide plate 7, a second support arm 801 fixed on the horizontal plate 8, and a kit 10 rotatably connected to the second support arm 801. The kit 10 slidably fits with the rotating sleeve 9. The kit 10 is respectively connected to a plurality of sleeve plates 12 through a plurality of connecting rods 13. The two ends of the connecting rod 13 are rotatably connected to the kit 10 and the sleeve plate 12, respectively. The horizontal plate 8 is also connected to an active drive component located inside the housing 1. The active drive component can cause the horizontal plate 8 to move along the axial direction of the rotating sleeve 9 and is connected to the air blowing structure.

[0052] It should be emphasized that, in order to ensure that the high-voltage line 2 is located in the center of the multiple cleaning components 14 during installation, the first support arm 701, the second support arm 801, the rotating sleeve 9, and the kit 10 are all provided with notches.

[0053] Whenever the walking drive structure stops operating, the active drive component works, first driving the horizontal plate 8 to move towards the outside of the housing 1. Correspondingly, the horizontal plate 8 drives the kit 10 to slide away from the housing 1 on the rotating sleeve 9 through the second support arm 801. Then, the kit 10 pushes the sleeve plate 12 to slide away from the rotating sleeve 9 on the guide arm 11 through the connecting rod 13, so that the multiple cleaning components 14 perform an expansion action to improve the blowing effect of the subsequent air blowing structure on the ice and snow accumulated in the cleaning components 14.

[0054] After the expansion of multiple cleaning components 14 is completed, the blowing structure will be triggered as the active driving component continues to move, blowing hot air into the cleaning components 14, thereby cleaning the cleaning components 14 and preventing the accumulation of too much ice and snow in the cleaning components 14 due to long-term operation of the equipment, which would result in poor ice and snow removal effect.

[0055] Please refer to it again. Figure 5 and Figure 9 The air-blowing structure includes a long box 17 fixed inside the housing 1, a piston plate 19 slidably sealed inside the long box 17, and a push rod 20 fixedly connected to the piston plate 19. The push rod 20 is connected to the active drive assembly. A one-way valve on the outer wall of the housing 1 is connected to the side of the long box 17, and an air supply component 15 is also connected to it via a conduit. After the multiple cleaning components 14 complete their expansion, the outer wall of the cleaning component 14 is sealed to the inner wall of the air supply component 15. The push rod 20 passes through a fixing plate 18 fixed to the port of the long box 17 and is slidably connected to the fixing plate 18. A cylindrical spring 21 is sleeved on the outer periphery of the push rod 20, and the two ends of the cylindrical spring 21 are respectively connected to the fixing plate 18 and the piston plate 19.

[0056] Furthermore, a heating wire can be installed inside the long box 17 to heat the internal gas, thereby effectively improving the cleaning effect on the cleaning component 14. A storage battery can be installed in both boxes 1 to power the equipment's power unit.

[0057] After the expansion action of the multiple cleaning components 14 is completed, the outer wall of the cleaning component 14 and the inner wall of the air supply component 15 are sealed together (both the outer wall of the cleaning component 14 and the inner wall of the air supply component 15 are provided with ventilation holes). As the active drive component continues to move, the columnar spring 21 will rebound, and the piston plate 19 will slide in the long box 17. Specifically, the piston plate 19 slides away from the fixed plate 18 in the long box 17. At this time, the one-way valve connected to the side of the long box 17 is not open, while the one-way valve in the air hole of the cleaning component 14 is open. As a result, the gas in the long box 17 will be pushed out and blown into the cleaning component 14 through the conduit and the air supply component 15, and then discharged through the air hole. This has the effect of blowing out the ice and snow accumulated in the cleaning component 14, preventing the accumulated ice and snow from condensing due to the low temperature working environment and affecting the cleaning and obstacle removal performance of the equipment on the high-voltage line 2.

[0058] Conversely, after the hot air is blown out, the active drive component resets, which first causes the push rod 20 to pull the piston plate 19 to slide towards the fixed plate 18 in the long box 17. The column spring 21 is compressed. During this process, the one-way valve in the air hole on the cleaning component 14 is not open, while the one-way valve on the side of the long box 17 is open. Thus, external air can be drawn into the long box 17 for heating and storage, and then blown towards the cleaning component 14 after the next travel drive structure stops running.

[0059] Please refer again. Figure 5 , Figure 7 as well as Figure 9 The active drive assembly includes two electric push rods 22 installed inside the housing 1 and a drive arm 23 fixedly connected to the movable ends of the two electric push rods 22. A protruding post 24 is fixed on the drive arm 23, and a transmission plate 16 is fixed on the horizontal plate 8. The transmission plate 16 has a through groove adapted to the protruding post 24, the protruding post 24 passes through the through groove and is slidably connected to the transmission plate 16, and the through groove includes a connected inclined section 1601 and a vertical section 1602.

[0060] With attachment Figure 1Taking the state as an example, at this time, the multiple cleaning components 14 are in a retracted state, and the protruding post 24 is located at the end of the inclined section 1601 away from the vertical section 1602. When the walking drive structure stops running, the electric push rod 22 will drive the drive arm 23 to move upward in the housing 1. Correspondingly, the protruding post 24 will pass through the inclined section 1601 and the vertical section 1602 in sequence. The protruding post 24 slides with the transmission plate 16 through the inclined section 1601, causing the transmission plate 16 to drive the horizontal plate 8. When the horizontal plate 8 moves away from the housing 1, the second support arm 801 drives the kit 10 to slide away from the housing 1 on the rotating sleeve 9, causing the multiple cleaning components 14 to expand until the protrusion 24 enters the vertical section 1602. The outer wall of the cleaning component 14 is sealed to the inner wall of the air supply component 15. Subsequently, as the protrusion 24 continues to move away from the inclined section 1601 along the vertical section 1602, the column spring 21 rebounds, and the gas in the long box 17 is discharged to the cleaning component 14.

[0061] The drive arm 23 is fixedly connected to a follower plate 25. The follower plate 25 is provided with a groove adapted to the push rod 20. The end of the push rod 20 away from the piston plate 19 extends into the groove and is slidably connected to the follower plate 25. The groove includes a first vertical groove 2501, a second vertical groove 2502, a horizontal groove 2503, a first return groove 2504, and a second return groove 2505 connected together. The end of the second return groove 2505 away from the first return groove 2504 is connected to the first vertical groove 2501 and the second vertical groove 2502. The first return groove 2504 is parallel to the first vertical groove 2501 and the second vertical groove 2502. The second return groove 2505 is inclined. The follower plate 25 is also rotatably provided with a deflector 26. The deflector 26 is located at the end of the second return groove 2505 away from the first return groove 2504, and the rotating shaft is connected to a torsion spring.

[0062] With attachment Figure 1Taking the state as an example, at this time, the end of the push rod 20 away from the piston plate 19 is located at the end of the first vertical groove 2501 away from the second vertical groove 2502. When the protrusion 24 slides along the inclined section 1601, under the limiting action of the deflector 26, the first vertical groove 2501 and the second vertical groove 2502 pass through the push rod 20 in sequence. After the push rod 20 is flush with the horizontal groove 2503, the column spring 21 will rebound. Before this, the protrusion 24 has entered the vertical section 1602, that is, the expansion action of the multiple cleaning parts 14 has been completed. The column spring 21 rebounds, and the push rod 24... The end of rod 20 away from the piston plate 19 slides along the transverse groove 2503 toward the first return groove 2504, so that the piston plate 19 discharges the hot air in the long box 17 to the cleaning component 14. It should be noted that although the rebound of the column spring 21 is rapid, it still requires a certain amount of time. In order to avoid the end of the push rod 20 away from the piston plate 19 getting stuck in the transverse groove 2503 without interrupting the movement of the electric push rod 22, the width of the transverse groove 2503 can be widened, that is, the width is greater than the diameter of the push rod 20, so as to provide enough time for the rebound of the column spring 21.

[0063] After the end of the push rod 20 away from the piston plate 19 reaches the connection between the first return groove 2504 and the transverse groove 2503, the blowing process ends. Immediately afterwards, the electric push rod 22 drives the drive arm 23 and the follower plate 25 to move downwards and reset. During this process, the first return groove 2504 and the second return groove 2505 pass through the push rod 20 sequentially. Because the second return groove 2505 is inclined, it causes the push rod 20 to reposition. The push rod 20 pulls the piston plate 19 to slide towards the fixed plate 18 within the long box 17, compressing the cylindrical spring 21. This process is a evacuation and storage process. During the latter part of the stroke of the follower plate 25 moving upward and resetting, the push rod 20 will cause the deflector 26 to deflect towards the second vertical groove 2502. The end of the first vertical groove 2501 away from the second vertical groove 2502 will re-align with the end of the push rod 20 away from the piston plate 19.

[0064] Please refer to it again. Figure 5The walking drive structure includes two walking wheels 6 rotatably mounted on the housing 1. The rotation shafts of the two walking wheels 6 are connected by a first belt. The rotation shaft of one walking wheel 6 is connected to the output end of a drive motor 5 mounted on the housing 1, and the rotation shaft of the other walking wheel 6 is connected to the rotating sleeve 9 through the transmission structure. A mounting arm 30 is fixed to the side of the housing 1. The transmission structure includes a gear set on the mounting arm 30 and a transmission shaft 27 rotatably mounted on the housing 1. One end of the transmission shaft 27 is connected to the rotation shaft of the walking wheel 6 through a bevel gear set 28, and the other end is connected to the gear set through a second belt. The gear set engages with teeth on the outer wall of the rotating sleeve 9.

[0065] Furthermore, the gear set includes a first gear and a second gear rotatably mounted on the mounting arm 30. The rotation shafts of the first gear and the second gear are connected by a third belt, which is used to connect the rotation shaft of the first gear to the transmission shaft 27.

[0066] Secondly, the bevel gear set 28 includes a first bevel gear fixedly installed coaxially with the walking wheel 6 and a second bevel gear fixed on the transmission shaft 27, and the second bevel gear meshes with the first bevel gear;

[0067] The drive motor 5 drives the two walking wheels 6 to rotate synchronously and in the same direction, enabling the equipment to move on the high-voltage line 2. At the same time, the rotation shaft of the walking wheels 6 drives the transmission shaft 27 to rotate through the bevel gear set 28. The transmission shaft 27 then drives the first gear and the second gear to rotate synchronously and in the same direction through the second belt. The first gear and the second gear both engage with the teeth on the outer wall of the rotating sleeve 9. Since the rotating sleeve 9 has a notch for easy equipment installation, the first gear and the second gear are provided. During the synchronous rotation of the first gear and the second gear, at least one of them engages with the teeth on the outer wall of the rotating sleeve 9, thereby ensuring the continuous rotation of the rotating sleeve 9. That is, the rotating sleeve 9 drives multiple cleaning components 14 to continuously perform circular motion around the high-voltage line 2 through the guide arm 11 and the sleeve plate 12.

[0068] Furthermore, by using the transmission structure to establish a linkage between the walking wheel 6 and the rotating sleeve 9, the walking of the equipment and the snow removal action of the cleaning component 14 can be synchronized. In actual implementation, the operation of the equipment is remotely controlled by ground personnel. If the walking of the equipment and the snow removal action of the cleaning component 14 use different drive sources, it will complicate the operation of the personnel. On the other hand, if the personnel control the equipment to walk before controlling the cleaning component 14 to perform the snow removal action, it will cause the walking of the equipment to be obstructed, which may damage the equipment and affect the stability of the equipment on the high-voltage line 2. If the personnel have already controlled the cleaning component 14 to perform the snow removal action but have not controlled the equipment to walk, the conical needles on the inner wall of the cleaning component 14 may damage the outer sheath of the high-voltage line 2 as the cleaning component 14 continues to operate in place.

[0069] As another embodiment of the present invention, a high-voltage line cleaning method is also proposed, which uses the aforementioned cleaning and obstacle removal equipment and includes the following steps:

[0070] Step 1: Install the equipment onto the high-voltage line 2, ensuring that the multiple cleaning components 14 surround the high-voltage line 2;

[0071] Step 2: The walking drive structure is activated, driving the equipment to move along the high-voltage line 2. At the same time, the walking drive structure drives multiple cleaning components 14 to make circular motion around the high-voltage line 2 through the transmission structure, performing the removal action on the ice and snow on the high-voltage line 2.

[0072] Step 3: The walking drive structure stops operating, and the opening and closing drive structure drives multiple cleaning components 14 to perform expansion actions.

[0073] Step four: After the expansion action of multiple cleaning components 14 is completed, the air blowing structure is triggered, and hot air is blown onto the cleaning components 14.

[0074] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
