[0002] Ice and snow on high-voltage lines pose great challenges to the safe operation of the power system, transportation and residents' lives. Therefore, taking effective anti-icing and de-icing measures to improve the disaster resistance of the power grid is an important task to ensure power supply.

[0003] To this end, a high-voltage line snow removal robot is usually used to complete the cleaning and obstacle removal work of the high-voltage lines to ensure the safe operation of the power system. Specifically, the robot will be equipped with ice and snow removal tools, and the cleaning and obstacle removal function of the high-voltage lines will be realized through the rotation of the tools.

[0004] However, existing high-voltage line snow removal robots usually work continuously. Due to the harsh working environment (low temperature), the ice and snow removed from the high-voltage lines tend to gradually accumulate on the cutter and condense on the cutter after a long time.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1-Figure 9 , In an embodiment of the present invention, a high-voltage transmission line mounted cleaning and obstacle removal device is used to remove ice and snow on two high-voltage lines 2 arranged in parallel, which includes two sets of cleaning mechanisms installed oppositely; The cleaning mechanism comprises a box body 1 and two sets of auxiliary walking wheels arranged on the box body 1, and the cleaning mechanism further comprises: A walking drive structure is installed on the box body 1, and is connected to a plurality of cleaning members 14 distributed along the circumferential direction through a transmission structure. The cleaning members 14 are arranged in an arc shape, and a conical surface is arranged on the inner side. A plurality of conical needle bodies are arranged on the conical surface. The interior of the cleaning member 14 is hollow, and a plurality of air holes are arranged on the conical surface. A one-way valve is arranged in the air hole. The plurality of cleaning members 14 are respectively matched with a plurality of groups of blowing structures arranged on the box body 1; Among them, the walking drive structure can drive the multiple cleaning members 14 to make circular motion around the high-voltage line 2 through the transmission structure, so that the conical needle body can perform a cleaning action on the ice and snow on the high-voltage line 2, and the transmission structure is also connected to a stretching and closing drive structure that can prompt the multiple cleaning members 14 to perform expansion or contraction actions. When the walking drive mechanism stops moving and the expansion action of the multiple cleaning members 14 is completed, the blowing structure is triggered to blow hot air into the cleaning members 14. When the multiple cleaning members 14 remain in a contracted state, an obstacle removal tool is formed.

[0030] It is also necessary to explain that Figure 1 For example, during cleaning, the plurality of cleaning members 14 are in contact with each other in sequence and surround the high-voltage line 2 to form a cylindrical structure, but the cylindrical structure is not closed. By controlling the number of the cleaning members 14, the lower part of the cylindrical structure is provided with a notch (see the attached Figure 4 ), so that, in the specific implementation, when the staff installs the equipment, it is convenient for the high-voltage line 2 to be surrounded by the multiple cleaning members 14 after the installation is completed. In this regard, the walking auxiliary wheel group includes an assembly arm 3 fixed on the box body 1 and two lateral wheels 4 arranged on the assembly arm 3, and the two lateral wheels 4 are each equipped with a movable block (not numbered in the figure) slidably arranged on the assembly arm 3, and the movable block is fastened to the assembly arm 3 by bolts. By adjusting the positions of the two movable blocks, the two lateral wheels 4 can clamp the high-voltage line 2, thereby having a stabilizing effect on the walking of the equipment. Finally, the two boxes 1 can be fixed to improve the overall stability of the equipment.

[0031] When working, the travel drive structure works, and the whole device moves along the high-voltage line 2. At the same time, the travel drive structure can drive the plurality of cleaning members 14 to make circular motion around the high-voltage line 2 through the transmission structure, and then utilize the conical needle body on the inner conical surface of the cleaning member 14 to effectively remove ice and snow on the high-voltage line 2; During the entire working process, the travel drive structure will stop running periodically. At this time, the opening and closing drive structure drives the multiple cleaning members 14 to perform an expansion action. Then, the blowing structure blows air into the cleaning members 14 to disperse the ice and snow accumulated on the inner wall of the cleaning members 14. As the working time increases, ice and snow are likely to accumulate on the inner walls of the multiple cleaning members 14. Since the working environment temperature of the equipment is relatively low, these ice and snow will soon condense into ice. At this time, it will affect the effect of the conical needle body on removing ice and snow on the high-voltage line 2, and even hinder the movement of the equipment on the high-voltage line 2, thereby causing the travel drive structure to malfunction; Therefore, in the present application, a plurality of movable cleaning parts 14 are provided. During the entire working process, the travel drive structure stops running periodically. First, the opening and closing drive structure drives the plurality of cleaning parts 14 to expand, thereby enhancing the effect of the subsequent blowing structure to blow away the accumulated ice and snow, thereby realizing the self-cleaning function of the equipment, enabling the equipment to overcome the harsh working environment by itself, ensuring normal operation, and avoiding adverse effects on the equipment's operation due to working environment factors.

[0032] Please refer again Figure 1 , Figure 6 , Figure 7 as well as Figure 8 The opening and closing driving structure includes a guide assembly installed on the side of the box body 1 and a push-pull assembly connecting the guide assembly and the plurality of cleaning members 14, and the guide assembly is connected to the travel driving structure through the transmission structure. The guide assembly includes a guide plate 7 fixed to the side of the box body 1, a first arm 701 fixed on the guide plate 7, and a rotating sleeve 9 rotatably connected to the first arm 701, the rotating sleeve 9 connects the transmission structure and the push-pull assembly, and a plurality of guide arms 11 are fixed to the outer wall of the rotating sleeve 9, each of the guide arms 11 is slidably sleeved with a sleeve plate 12, and the plurality of cleaning members 14 are respectively fixed to the plurality of sleeve plates 12. The push-pull assembly includes a horizontal plate 8 slidably sleeved with the guide plate 7, a second arm 801 fixed on the horizontal plate 8, and a sleeve 10 rotatably connected to the second arm 801, the sleeve 10 is slidably sleeved with the rotating sleeve 9, and the sleeve 10 is respectively connected to the 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 sleeve 10 and the sleeve plate 12 respectively. The cross plate 8 is also connected to an active driving component arranged inside the box body 1. The active driving component can cause the cross plate 8 to move axially along the rotating sleeve 9 and be connected to the blowing structure.

[0033] It should be emphasized that, in order to ensure that the high-voltage line 2 is located at the center of the plurality of cleaning members 14 during installation, the first arm 701 , the second arm 801 , the rotating sleeve 9 and the sleeve 10 are all provided with notches.

[0034] Whenever the travel drive mechanism stops running, the active drive assembly works, and will first drive the transverse plate 8 to move toward the outside of the box body 1. Correspondingly, the transverse plate 8 drives the set 10 to slide away from the box body 1 on the rotating set 9 through the second support arm 801. Then, the set 10 pushes the set plate 12 to slide away from the rotating set 9 on the guide arm 11 through the connecting rod 13, so that the multiple cleaning members 14 perform an expansion action to enhance the subsequent blowing structure's effect of blowing away the ice and snow accumulated in the cleaning members 14. After the expansion action of multiple cleaning members 14 is completed, as the active driving component continues to move, the blowing structure will be triggered to blow hot air into the cleaning members 14, thereby cleaning the cleaning members 14 and avoiding poor ice and snow removal effect due to excessive accumulation of ice and snow in the cleaning members 14 due to long-term operation of the equipment.

[0035] Please refer again Figure 5 and Fig. 9 The blowing structure includes a long box 17 fixed in the box body 1, a piston plate 19 sealingly and slidably arranged in 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 driving component, the side of the long box 17 is connected to a one-way valve arranged on the outer wall of the box body 1, and is also connected to the air supply member 15 through a conduit, when the plurality of cleaning members 14 complete the expansion action, the outer wall of the cleaning member 14 is sealed and fitted with the inner wall of the air supply member 15. The push rod 20 penetrates the fixed plate 18 fixed to the port of the long box 17 and is slidably connected to the fixed plate 18, and the outer periphery of the push rod 20 is sleeved with a columnar spring 21, and the two ends of the columnar spring 21 are respectively connected to the fixed plate 18 and the piston plate 19.

[0036] Furthermore, a heating wire may be provided in the long box 17 for heating the internal gas, thereby effectively improving the cleaning effect of the cleaning member 14, and batteries may be installed in the two boxes 1 to supply power to the power device of the equipment.

[0037] After the expansion action of the plurality of cleaning members 14 is completed, the outer wall of the cleaning member 14 is sealed and fitted with the inner wall of the air supply member 15 (the outer wall of the cleaning member 14 and the inner wall of the air supply member 15 are both provided with ventilation holes). As the active driving component continues to move, the cylindrical spring 21 will rebound, and thus 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 conductive, while the one-way valve in the air hole of the cleaning member 14 is conductive. Thus, the gas in the long box 17 will be pushed out and blown into the cleaning member 14 through the conduit and the air supply member 15, and then discharged through the air hole, which has a blowing effect on the ice and snow accumulated in the cleaning member 14, and prevents the accumulated ice and snow from condensing due to the low temperature working environment, thereby affecting the cleaning and obstacle removal performance of the equipment for the high-voltage line 2. On the contrary, after the hot air is blown, the active driving component is reset, which will first prompt the push rod 20 to pull the piston plate 19 to slide toward the fixed plate 18 in the long box 17, and the cylindrical spring 21 is compressed. During this process, the one-way valve in the air hole on the cleaning member 14 is not connected, while the one-way valve on the side of the long box 17 is connected. Therefore, external air can be drawn into the long box 17 for heating storage, and then blown to the cleaning member 14 after the next time the walking drive structure stops running.

[0038] Please visit again Figure 5 , Figure 7 as well as Fig. 9 The active driving assembly includes two electric push rods 22 installed in the box 1 and a driving arm 23 fixedly connected to the movable ends of the two electric push rods 22, a boss 24 is fixed on the driving arm 23, and a transmission plate 16 is fixed on the cross plate 8. The transmission plate 16 is provided with a through slot adapted to the boss 24, the boss 24 passes through the through slot and is slidably connected to the transmission plate 16, and the through slot includes a connected inclined section 1601 and a vertical section 1602.

[0039] Attach Figure 1 As an example, at this time, the plurality of cleaning members 14 are in a retracted state, the boss 24 is located at one end of the inclined section 1601 away from the vertical section 1602, and when the walking driving structure stops running, the electric push rod 22 will drive the driving arm 23 to move upward in the box body 1, and accordingly, the boss 24 will pass through the inclined section 1601 and the vertical section 1602 in sequence, and the boss 24 will slide with the transmission plate 16 through the inclined section 1601, so that the driven plate 16 drives the horizontal plate 8 When giving way occurs, the cross plate 8 can drive the kit 10 to slide on the rotating sleeve 9 away from the box body 1 through the second support arm 801, so that the multiple cleaning parts 14 perform an expansion action until the boss 24 enters the vertical section 1602, and the outer wall of the cleaning part 14 is sealed with the inner wall of the air supply part 15. Subsequently, when the boss 24 continues to move along the vertical section 1602 away from the inclined section 1601, the columnar spring 21 rebounds, and the gas in the long box 17 is discharged to the cleaning part 14.

[0040] The driving arm 23 is fixedly connected to a follower plate 25, and a groove body adapted to the push rod 20 is provided on the follower plate 25, and the end of the push rod 20 away from the piston plate 19 extends into the groove body and is slidably connected to the follower plate 25; the groove body 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 to each other, and the end of the second return groove 2505 away from the first return groove 2504 connects the first vertical groove 2501 and the second vertical groove 2502; wherein, the first return groove 2504 is parallel to the first vertical groove 2501 and the second vertical groove 2502, and the second return groove 2505 is inclined, and a deflection member 26 is also rotatably arranged on the follower plate 25, and the deflection member 26 is located at the end of the second return groove 2505 away from the first return groove 2504, and a torsion spring is connected to the rotating shaft.

[0041] Attach Figure 1 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 slot 2501 away from the second vertical slot 2502. When the boss 24 slides along the inclined section 1601, under the limiting action of the deflection member 26, the first vertical slot 2501 and the second vertical slot 2502 pass through the push rod 20 in sequence. After the second vertical slot 2501 is flush with the transverse slot 2503, the column spring 21 will rebound. Before this, the boss 24 has entered the vertical section 1602, that is, the expansion action of multiple cleaning members 14 has been completed, the column spring 21 rebounds, and the push rod 20 is pushed away. The end of the push 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 member 14. It should be noted that although the cylindrical spring 21 rebounds quickly, it still takes a certain amount of time. When the movement of the electric push rod 22 is not interrupted, in order to prevent the end of the push rod 20 away from the piston plate 19 from getting stuck in the transverse groove 2503, 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 cylindrical spring 21 to rebound. When 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 is completed. Then, the electric push rod 22 drives the follower arm 23 and the follower plate 25 to move down and reset. During this process, the first return groove 2504 and the second return groove 2505 first pass through the push rod 20 in sequence. Since the second return groove 2505 is inclined, it will cause the push rod 20 to give way. In particular, the push rod 20 pulls the piston plate 19 to slide toward the fixed plate 18 in the long box 17, and the cylindrical spring 21 is compressed. This process is an air extraction reserve process. In the latter part of the stroke when the follower plate 25 moves up and resets, the push rod 20 will cause the deflection member 26 to swing toward the second vertical groove 2502, and the end of the first vertical groove 2501 away from the second vertical groove 2502 will be re-aligned with the end of the push rod 20 away from the piston plate 19.

[0042] Please refer again Figure 5 The travel drive structure includes two travel wheels 6 rotatably mounted on the housing 1, and the rotation axes of the two travel wheels 6 are connected by a first belt, wherein the rotation axis of one of the travel wheels 6 is connected to the output end of the drive motor 5 mounted on the housing 1, and the rotation axis of the other travel 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, and the transmission structure includes a gear set provided 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 axis of the travel wheel 6 through a bevel gear set 28, and the other end is connected to the gear set through a second belt, and the gear set cooperates with the teeth provided on the outer wall of the rotating sleeve 9.

[0043] Further, the gear set includes a first gear and a second gear rotatably mounted on the mounting arm 30, the rotation axes of the first gear and the second gear are connected by a third belt, and the second belt is used to connect the rotation axis of the first gear and the transmission shaft 27; Secondly, the bevel gear set 28 includes a first bevel gear fixedly mounted coaxially with the travel wheel 6 and a second bevel gear fixed on the transmission shaft 27, and the second bevel gear is meshed with the first bevel gear; Wherein, the driving motor 5 drives the two walking wheels 6 to rotate synchronously and in the same direction, so that the equipment can walk on the high-voltage line 2. At the same time, the rotating shaft of the walking wheel 6 drives the transmission shaft 27 to rotate through the bevel gear set 28, and the transmission shaft 27 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 are both matched with the teeth arranged on the outer wall of the rotating sleeve 9. Since the rotating sleeve 9 is provided with a notch for facilitating the installation of the equipment, 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 meshes with the teeth on the outer wall of the rotating sleeve 9, so as to ensure the continuous rotation of the rotating sleeve 9, that is, the rotating sleeve 9 drives the plurality of cleaning members 14 to continuously perform circular motion around the high-voltage line 2 through the guide arm 11 and the sleeve plate 12; Furthermore, by utilizing 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 member 14 can be synchronized. Since in the specific implementation, the operation of the equipment is remotely controlled by the ground staff, if the walking of the equipment and the snow removal action of the cleaning member 14 use different driving sources, on the one hand, it complicates the staff's control. On the other hand, when the staff controls the equipment to walk before controlling the cleaning member 14 to perform the snow removal action, the walking of the equipment will be obstructed, which may damage the equipment and affect the stability of the equipment on the high-voltage line 2. When the staff has controlled the cleaning member 14 to perform the snow removal action but has not controlled the equipment to walk, as the cleaning member 14 continues to operate in situ, the conical needle body on its inner wall may cause damage to the outer skin of the high-voltage line 2.

[0044] As another embodiment of the present invention, a high-voltage line cleaning method is also proposed, using the cleaning and obstacle removal equipment, comprising the following steps: Step 1: Install the device on the high-voltage line 2, ensuring that the plurality of cleaning members 14 surround the high-voltage line 2; Step 2: The travel drive structure is started to drive the device to travel on the high-voltage line 2. At the same time, the travel drive structure drives the plurality of cleaning members 14 to perform circular motion around the high-voltage line 2 through the transmission structure to remove ice and snow on the high-voltage line 2. Step 3: the travel drive structure stops running, and the opening and closing drive structure drives the multiple cleaning members 14 to perform an expansion action; Step 4: After the expansion action of the multiple cleaning elements 14 is completed, the blowing structure is triggered to blow hot air toward the cleaning elements 14 .

[0045] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
