Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage line deicing, in particular to a high-voltage line deicing device for power maintenance. Background Art

[0002] Since the mid-20th century, my country's power transmission lines have suffered thousands of icing disasters of varying degrees. These incidents have led to various accidents, severely disrupting the normal operation of the power grid and causing significant inconvenience to people's lives. To reduce the occurrence of these accidents, numerous research institutions and universities have conducted research on high-voltage line de-icing technologies, achieving considerable success. While numerous de-icing methods are currently available both domestically and internationally, their mechanisms can be broadly categorized into thermal de-icing, mechanical de-icing, and natural de-icing.

[0003] Mechanical deicing is a method of using mechanical external force to force the ice on the wires to fall off. Currently, the main methods of mechanical deicing include pulley scraping, electromagnetic deicing and robotic deicing.

[0004] The high-voltage line de-icing robot not only clears ice from high-voltage lines, effectively maintaining power supply, but also eliminates risky manual labor and improves disaster relief efficiency. Equipped with a remote control module, the robot can be controlled from indoors, and a wireless camera allows workers to monitor de-icing operations and wire damage via video feed. A night-vision light also allows the robot to operate at night and in foggy and hazy conditions.

[0005] However, when the de-icing robot is working, it is easy to shake and walk unsteadily because it walks on a single high-voltage line and de-ices. If there is wind during the de-icing work, it is easy to fall.

[0006] In view of this, the present invention solves the above technical problems by proposing a high-voltage line deicing device for power maintenance. Summary of the Invention

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 7 As shown, the present invention is a high-voltage line deicing device for power maintenance;

[0039] The deicing robot 1 includes a deicing robot 1 and a high-voltage line 11; the deicing robot 1 can walk along the high-voltage line 11 and de-ice the high-voltage line 11;

[0040] Also included is an auxiliary mechanism 2;

[0041] The auxiliary mechanism 2 includes:

[0042] The clamping plates 21 are two in number and correspond to each other; the bottom positions of the two clamping plates 21 are rotatably connected by a rotating shaft; a distance is left between the tops of the two clamping plates 21 on opposite sides;

[0043] A fixing plate 22, the bottom end surfaces of the two clamping plates 21 are fixedly connected with a fixing plate 22; the inner wall of one of the fixing plates 22 is threadedly engaged with bolts 23 evenly arranged, and the bolts 23 are used to support the adjacent fixing plates 22;

[0044] Driving wheels 4, the inner walls of the two clamping plates 21 are rotatably connected with evenly arranged driving wheels 4, and the outer contour of the driving wheels 4 cooperates with the outer ring of the high-voltage wire 11;

[0045] Mounting plate 24, the end surface of the clamping plate 21 opposite to the end surface thereof is fixedly connected with a mounting plate 24;

[0046] The outer surface of the mounting plate 24 and the outer surface of the de-icing robot 1 are both provided with fixing heads 25, and the fixing heads 25 are connected to the mounting plate 24 and the de-icing robot 1 through threads; two baffles 26 are fixedly connected to the end surfaces of the two fixing heads 25 on opposite sides;

[0047] A driving rod 28 is provided on one side of the two fixed heads 25, and the two ends of the driving rod 28 extend between the two baffles 26 fixed to the two fixed heads 25, and are rotatably connected to the baffles 26 through a pin 27;

[0048] The driving rod 28 is a telescopic rod;

[0049] A rechargeable power source 3 is mounted on the inner walls of the two mounting plates 24. A first motor 31 is mounted on the inner walls of the mounting plates 24 and is electrically connected to the power source via a wire. The first motor 31 is started and stopped by a remote control of the de-icing robot 1. The output shaft of the first motor 31 extends out of the mounting plates 24. A flexible shaft 32 is fixedly connected to the drive shaft of the first motor 31, and a stainless steel ball 33 is fixedly connected to the other end of the flexible shaft 32.

[0050] The output shaft of the first motor 31 is fixedly connected to a surface of the side close to the mounting plate 24 with brushes 34 arranged evenly;

[0051] The rotating shafts on the two driving wheels 4 are fixedly connected to the output shaft of the second motor 41; the second motor 41 is electrically connected to the power supply via a wire; the second motor 41 is started and stopped by the remote control of the deicing robot 1;

[0052] On one side of the top of the two clamping plates 21 corresponding to each other, evenly arranged mounting grooves 42 are opened in the inner wall of the clamping plates 21, and a limit plate 43 is hinged in the mounting groove 42 via a torsion spring; the limit plate 43 can only rotate in one direction toward the inside of the clamping plate 21;

[0053] Both side end surfaces of the rotation axis position of each of the limiting plates 43 are provided with arc surfaces;

[0054] The outer surfaces of the two driving wheels 4 are wrapped with a rubber layer 44;

[0055] Uniformly arranged conical plastic blocks 45 are fixedly connected to the outer surfaces of the two driving wheels 4 , and the conical plastic blocks 45 can extend out of the rubber layer 44 .

[0056] In a specific embodiment, when using the deicing device to de-ice a high-voltage line 11, a worker first needs to climb to the location where the high-voltage line 11 is connected to the high-voltage line tower, and then the worker installs the de-icing robot 1 on the high-voltage line 11. Then, the worker installs the auxiliary mechanism 2 on the high-voltage line 11 on both sides of the high-voltage line 11 where the de-icing robot 1 is installed. If there is only a high-voltage line 11 on one side of the de-icing robot 1, the auxiliary mechanism 2 is only installed on the high-voltage line 11 on the side of the de-icing robot 1.

[0057] When installing the auxiliary mechanism 2, the staff first loosens the bolts 23 set on the fixing plate 22. During the loosening process of the bolts 23, the bolts 23 will gradually move away from the other fixing plate 22. At this time, the other fixing plate 22 is no longer limited by the bolts 23, so that the two clamping plates 21 can be rotated to both sides and separated. Then the staff manually rotates the clamping plates 21 so that the two clamping plates 21 are located on both sides of the high-voltage line 11 respectively. Then the staff pushes the two clamping plates 21 to make the two clamping plates 21 close to each other until the driving wheel 4 is in contact with the high-voltage line 11. Then the staff tightens the bolts 23. When the bolts 23 are tightened, the bolts 23 will gradually squeeze Another mounting plate 24, when the two mounting plates 24 are in a parallel state, the clamping plate 21 is limited and fixed, so that the auxiliary mechanism 2 can be installed on the high-voltage line 11. Then the staff extends the two sides of the driving rod 28 between the two baffles 26 fixed on the fixed head 25, and uses the pin 27 to rotate the driving rod 28 to the limit baffle 26. Since the driving rod 28 is a telescopic rod, it can adapt to adjacent high-voltage lines 11 of different distances. At the same time, the staff can choose driving rods 28 of different lengths according to the distance between adjacent high-voltage lines 11. At the same time, the tightness of the auxiliary mechanism 2 installed on the high-voltage line 11 can be adjusted by turning the bolt 23;

[0058] Then the staff uses the remote control to control the de-icing robot 1 to walk on the high-voltage wire 11 and de-ice the high-voltage wire 11. During the walking and de-icing process of the de-icing robot 1, the driving rod 28 will be driven to move. At the same time, the driving rod 28 drives the auxiliary mechanism 2 to move on the high-voltage wires 11 on both sides of the de-icing robot 1. During the movement of the auxiliary mechanism 2, the driving wheel 4 will rotate. By arranging the auxiliary mechanism 2 on the high-voltage wires 11 on both sides of the de-icing robot 1, and the auxiliary mechanism 2 supporting and limiting the de-icing robot 1 through the driving rod 28, it is possible to prevent the de-icing robot 1 from shaking, walking unstably or even falling when walking on a single high-voltage wire 11. At the same time, due to the existence of the auxiliary mechanism 2, when the de-icing robot 1 falls, the auxiliary mechanism 2 can pull the de-icing robot 1 through the driving rod 28 to prevent the de-icing robot 1 from falling to the ground and causing damage.

[0059] Specifically, since the rotating shaft on the driving wheel 4 is fixedly connected to the output shaft of the second motor 41, when the de-icing robot 1 is working on the high-voltage wire 11, the staff can control the rotation of the second motor 41 through the remote control. During the rotation of the second motor 41, the driving wheel 4 can be driven to rotate, so that the auxiliary mechanism 2 can be moved on the high-voltage wire 11 through the driving wheel 4. In this process, the resistance of the de-icing robot 1 to the movement on the high-voltage wire 11 can be reduced. At the same time, if the de-icing robot 1 falls, the auxiliary mechanism 2 can pull the de-icing robot 1 while moving on the high-voltage wire 11 through the rotating driving wheel 4, and drive the de-icing robot 1 to the initial position;

[0060] At the same time, when the auxiliary mechanism 2 moves on the high-voltage wire 11, the staff controls the first motor 31 in the mounting plate 24 to rotate through the remote control. During the rotation of the first motor 31, the flexible shaft 32 can be driven to rotate, and the stainless steel ball 33 can be driven to knock the high-voltage wire 11, so that the high-voltage wire 11 on both sides of the de-icing robot 1 can be pre-de-iced. When the de-icing robot 1 uses the de-icing robot 1 to de-ice the pre-deiced high-voltage wire 11 again, the difficulty of de-icing the pre-deiced high-voltage wire 11 can be reduced, so that the ice on the high-voltage wire 11 can be removed more easily. If the ice on the pre-deiced high-voltage wire 11 is cleared relatively cleanly, it is not necessary to use the de-icing robot 1 to de-ice the pre-deiced high-voltage wire 11 again. At the same time, during the rotation of the first motor 31, the brush 34 can be driven to rotate. During the rotation of the brush 34, the high-voltage wire 11 that has been knocked can be cleaned, so that the crushed ice or ice cubes attached to the high-voltage wire 11 can be swept off, thereby improving the de-icing effect of the high-voltage wire 11.

[0061] More specifically, since a plurality of limit plates 43 are unidirectionally hinged on one side of the top of the clamping plate 21, when the auxiliary mechanism 2 moves on the high-voltage line 11 and passes an obstacle, the obstacle will first contact the limit plate 43 close to the obstacle. When the obstacle contacts the limit plate 43, the limit plate 43 will be squeezed to rotate toward the inside of the clamping plate 21, thereby increasing the distance between the two phase plates on the opposite side to allow the obstacle to pass. Then the obstacle will pass through the first limit plate 43. After the obstacle passes through the first limit plate 43, the limit plate 43 will return to its original state under the action of the torsion spring, so that it can be rotated to a position above the high-voltage line 11 again, thereby blocking the high-voltage line 11 again. Then the obstacle passes through the following limit plates 43 in turn. After each limit plate 43 is passed, the limit plate 43 will return to its original state to block the high-voltage line 11. In this process, when the obstacle passes through one of the limit plates 43, the other limit plates 43 can block the high-voltage line 11, preventing the high-voltage line 11 from escaping from the auxiliary mechanism 2.

[0062] At the same time, since both end surfaces of the limiting plate 43 at the rotation axis are provided with arc surfaces, when an obstacle passes through the arc surface on the limiting plate 43, the obstacle can be pressed against the limiting plate 43 along the arc surface, thereby making it easier for the limiting plate 43 to rotate toward the inside of the clamping plate 21;

[0063] Furthermore, since the outer surface of the driving wheel 4 is wrapped with a rubber layer 44, when the driving wheel 4 contacts the high-voltage wire 11, the high-voltage wire 11 will squeeze the rubber layer 44, thereby improving the degree of contact between the high-voltage wire 11 and the rubber layer 44 on the driving wheel 4, thereby increasing the friction between the high-voltage wire 11 and the rubber layer 44;

[0064] At the same time, since the outer surface of the driving wheel 4 is fixedly connected with evenly arranged conical plastic blocks 45, and the conical plastic blocks 45 can extend out of the rubber layer 44, when the rubber layer 44 is squeezed by the high-voltage wire 11, the rubber layer 44 will become thinner. When the rubber layer 44 becomes thinner, the conical plastic blocks 45 will extend out from the rubber layer 44 and be squeezed on the high-voltage wire 11. In this process, the friction between the driving wheel 4 and the high-voltage wire 11 can be further improved. At the same time, when the de-icing robot 1 slips on the high-voltage wire 11, the auxiliary mechanism 2 can drive the de-icing robot 1 to move.
