In severe cases, power outages may occur. Therefore, it is necessary to de-ice the transmission lines.

[0003] For example, the patent with the national authorized patent announcement number CN211830133U discloses a power transmission line deicing device, which includes: a shell, which is surrounded by a top plate, a bottom plate, a first side plate and a second side plate, and the first side plate is provided with an inlet notch for the transmission line to enter the shell; an upper clamping assembly, including a friction wheel rotatably carried in the shell, and the friction wheel is located above the inlet notch; a lower clamping assembly, which is arranged in the shell and located below the inlet notch, and the lower clamping assembly includes a clamping wheel rotatably carried by the shell; a deicing mechanism, including an ice hammer and a driving assembly for driving the ice hammer to hit the transmission line. In specific operation, the shell is lifted to one side of the transmission line, and the wire is placed in the shell through the inlet notch, so that the friction wheel and the clamping wheel clamp the transmission line, and then the shell is moved, and the ice hammer can hit the inlet line of the transmission line to de-ice. The present invention has high ice efficiency, low production cost and high safety.

[0004] However, the above-mentioned power transmission line deicing device breaks the ice layer on the surface of the power transmission line by rolling it with a friction wheel, and this deicing method cannot fully cover the surface of the power transmission line, which may lead to insufficient deicing. Summary of the invention

[0007] Furthermore, an ice-breaking knife is fixedly mounted on the outer surface of the cone head, and the ice-breaking knife can cut and break the top of the ice cylinder peeled off from the power transmission line by the ice-breaking mechanism.

[0008] Furthermore, a connecting arm is fixedly installed on the outer surface of the circular shell, and a stopping ring is fixedly installed on one end of the connecting arm, so that the stopping ring can be suspended and surrounded on the periphery of the transmission line, so that after the propulsion mechanism pushes the ice-breaking mechanism to the head or tail of the transmission line, the stopping ring can be pressed against one end of the tower of the transmission line to stop the propulsion mechanism from continuing to push.

[0009] Furthermore, the ice-breaking mechanism includes a first dual-axis motor, which is fixedly installed in a round shell, and the output shaft ends on both sides of the first dual-axis motor are fixedly installed with connecting rods, and the ends of the two connecting rods are fixedly installed with first gears, the first gear is meshed with the second gear, and one end of the second gear is fixedly installed with a connecting tube, and the second gear rotates in the second inner tube through the connecting tube.

[0010] Furthermore, limit rings are fixedly installed on both sides of the outer surface of the first inner tube; The other end of the second gear contacts one end of the limiting ring, so that the second gear is rotationally limited between the second inner tube and the limiting ring.

[0011] Furthermore, the connecting tube passes through the second inner tube and is connected to the crushing teeth. When the crushing teeth are driven to rotate by the first dual-axis motor, the ice layer on the outer surface of the transmission line can be crushed and peeled off through the propulsion of the propulsion mechanism.

[0012] Furthermore, the propulsion mechanism includes two sets of driving wheels, with rotating rods fixedly installed on both sides of the driving wheels. The driving wheels are rotatably installed in the connecting tube through the rotating rods. An arc ring is provided on the outer surface of the driving wheel.

[0013] Further, first bevel gears are fixedly mounted on both sides of the driving wheel, the first bevel gears are meshed with second bevel gears, the second bevel gears are fixedly mounted on one end of the output shaft of the second dual-axis motor, and the second dual-axis motor is fixedly mounted in the round shell; The driving wheel can be driven by the second dual-axis motor to rotate against the outer surface of the transmission line, thereby enabling the driving wheel to propel the round shell to move on the outer surface of the transmission line.

[0014] The present invention also discloses a working method of the power transmission line anti-icing and deicing device, which includes the following process: When breaking the ice layer on the outer surface of the transmission line, the ice-breaking mechanism and the propulsion mechanism are started, and the ice-breaking mechanism rotates in the second inner tube in the cone heads on both sides of the round shell, so that the ice-breaking mechanism can be mounted on the outer surface of the transmission line to perform a rotating ice-breaking operation; While the ice-breaking mechanism is rotating, the propulsion mechanism can push the round shell and the cone head to move and propel on the outer surface of the transmission line. While the propulsion is being achieved, the ice-breaking mechanism continues to break the ice layer on the outer surface of the transmission line. Then, as the propulsion mechanism continues to push, the breaking teeth of the ice-breaking mechanism can be driven to break the ice cylinder.

[0015] The present invention also discloses a working method of the power transmission line anti-icing and deicing device, which includes the following process: When breaking the ice layer on the outer surface of the transmission line, the first double-shaft motor and the second double-shaft motor are started, and the first double-shaft motor can drive the first gear to mesh with the second gear to rotate, so that the second gear can drive the crushing teeth at one end of the connecting tube to rotate in the second inner tube, and the crushing teeth rotate in the second inner tube while also rotating in contact with the outer surface of the transmission line, so that the connecting tube can drive the crushing teeth to break and peel off the ice layer on the outer surface of the transmission line; The second dual-axis motor drives the second bevel gears at both ends to mesh and transmit the two sets of first bevel gears to rotate, so that the two sets of first bevel gears drive the two sets of driving wheels to rotate relative to each other on the outer surface of the transmission line through the rotating rods on both sides, so that the driving wheels can push the round shell to move on the outer surface of the transmission line, thereby achieving propulsion while allowing the crushing teeth to continuously crush the ice layer on the outer surface of the transmission line, and then as the driving wheel continues to push, it can drive the ice breaker at one end of the cone head to cut the ice cylinder into pieces.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention discloses an anti-icing and de-icing device for power transmission lines, comprising a round shell, a cone head, an ice-breaking mechanism and a propulsion mechanism. When breaking the ice layer on the outer surface of the power transmission line, the ice-breaking mechanism and the propulsion mechanism can be started, and the ice-breaking mechanism will rotate in the second inner tubes in the cone heads on both sides of the round shell, so that the ice-breaking mechanism can be set on the outer surface of the power transmission line to perform a rotating ice-breaking operation, and while the ice-breaking mechanism rotates, the propulsion mechanism can push the round shell and the cone head to move and propel on the outer surface of the power transmission line, so that the ice-breaking mechanism continuously breaks the ice layer on the outer surface of the power transmission line while propulsion is achieved, and since the ice-breaking end of the ice-breaking mechanism is cylindrical, it can break thicker ice layers into cylindrical shapes, and then with the continuous pushing of the propulsion mechanism, the ice-breaking knife at one end of the cone head can be driven to cut the ice cylinder into pieces, until it is pushed to the tail of the power transmission line, and then the stop ring can be pressed against one end of the pole tower of the power transmission line to stop pushing until the ice-breaking operation is needed again. , it can be moved from the tail of the transmission line to the head of the transmission line again, thereby realizing the ice-breaking operation of the entire section of the transmission line, wherein the ice-breaking mechanism can be moved along the entire length of the transmission line through the push of the propulsion mechanism, advancing from the starting point of the line to the tail, and realizing all-round ice crushing. This design solves the problem that the traditional de-icing method can only handle local treatment, ensures that the entire transmission line can be effectively de-iced in icy and snowy weather, avoids the problem of local ice not being cleared, and through the ice-breaking mechanism sliding sleeve on the outer surface of the transmission line, the ice-breaking operation can be evenly performed on the surface of the entire line. Compared with the traditional local contact method, this all-round ice-breaking operation can ensure that the ice layer is effectively cleared in each section of the transmission line, avoiding the problem of certain areas being ignored or not completely cleared, especially for long-distance transmission lines or lines in complex environments, which can significantly improve the de-icing effect.

[0017] Furthermore, the present invention provides a specific propulsion mechanism. Through the design of the first dual-axis motor, the first gear, the connecting tube, the second gear and the breaking teeth, when breaking the ice layer on the outer surface of the transmission line, the first dual-axis motor and the second dual-axis motor can be started, and the first dual-axis motor can drive the first gear to mesh with the second gear to rotate, so that the second gear can drive the breaking teeth at one end of the connecting tube to rotate in the second inner tube, and the breaking teeth rotate in the second inner tube while also rotating in contact with the outer surface of the transmission line, so that the connecting tube can drive the breaking gear to break and peel off the ice layer on the outer surface of the transmission line, and because the breaking tooth sliding sleeve rotates on the outer surface of the transmission line, it can ensure that the ice layer is evenly and accurately peeled off, avoiding the situation where the ice layer remains on the surface or the local crushing is not thorough, and accurate peeling helps to ensure that there is no ice accumulation on the entire power line surface, avoiding the problem of incomplete removal of ice in some areas.

[0018] Furthermore, the present invention provides a specific ice-breaking mechanism. Through the design of the second double-axis motor, the second bevel gear, the driving wheel and the first bevel gear, when the breaking teeth break the ice layer on the outer surface of the transmission line, the second double-axis motor can be started at the same time to drive the second bevel gears at both ends to mesh and drive the two groups of first bevel gears to rotate. The two groups of first bevel gears can drive the two groups of driving wheels to rotate relative to each other on the outer surface of the transmission line through the rotating rods on both sides, so that the driving wheel can propel the circular shell to move on the outer surface of the transmission line, thereby achieving the propulsion while allowing the breaking teeth to continue to break the ice layer on the outer surface of the transmission line. This continuous operation mode can process the ice layer of a longer transmission line in a shorter time, reduce the number of frequent starts and stops of equipment, and further improve work efficiency.

[0019] Furthermore, the circular shell is fixedly installed with a stop ring through a connecting arm. The stop ring can be suspended and sleeved on the periphery of the transmission line. When it is pushed to the tail of the transmission line, the stop ring can be pressed against one end of the tower of the transmission line to stop pushing further. When ice breaking operation is needed again, it can be moved from the tail of the transmission line to the head of the transmission line again, thereby realizing ice breaking operation on the entire section of the transmission line.

Moreover, by sliding the ice-breaking mechanism 2 on the outer surface of the transmission line, ice-breaking operations can be performed evenly on the surface of the entire line. Compared with the traditional local contact method, this all-round ice breaking operation can ensure that the ice layer is effectively cleared in each section of the transmission line, avoiding the problem of certain areas being ignored or not completely cleared, especially for long-distance transmission lines or lines in complex environments, which can significantly improve the de-icing effect.

Since the crushing teeth 206 are cylindrical, they can crush the thicker ice layer into a cylindrical shape. Then, with the continuous pushing of the driving wheel 303, the ice breaker 104 at one end of the cone head 103 can be driven to cut the ice cylinder into pieces, until it is pushed to the tail end of the transmission line, the stop ring 102 can be pressed against one end of the tower of the transmission line to stop pushing, until the ice breaking operation is needed again, it can be moved from the tail end of the transmission line to the head of the transmission line again, thereby realizing the ice breaking operation of the entire section of the transmission line.

[0040] The present invention can perform ice breaking operations evenly on the surface of the entire line by sliding the breaking teeth 206 onto the outer surface of the transmission line. Compared with the traditional local contact method, this all-round ice breaking operation can ensure that the ice is effectively cleared in every section of the transmission line, avoiding the problem of certain areas being ignored or not completely cleared. This can significantly improve the deicing effect, especially for long-distance transmission lines or lines in complex environments.
