Description

Technical Field

[0001] The present invention relates to the technical field of deicing of power transmission lines, and more particularly to a device for removing ice from power transmission lines. Background Art

[0002] In power transmission systems, transmission lines are key vehicles for energy transmission, and their safe and stable operation is crucial. However, in cold climates, icing of transmission lines is a frequent occurrence, posing a significant challenge to the power industry. When temperatures drop below 0°C and the air contains supercooled water droplets or ice crystals, these substances quickly freeze upon contact with transmission lines, gradually forming a layer of ice. The thickness of the ice increases over time and environmental conditions, posing a variety of hazards to transmission lines.

[0003] Ice accumulation increases the weight of transmission lines, causing them to bear forces far exceeding their design loads. This not only increases line sag and alters the normal tension distribution, but can also shorten the safe distance between the lines and surrounding objects, leading to short-circuit failures. In severe cases, excessive ice can even break transmission lines, causing towers to collapse under the weight, resulting in widespread power outages and significant losses to society. Statistics show that power outages caused by ice accumulation on transmission lines result in significant economic losses for power companies and users each year.

[0004] The deicing methods of existing devices are too simple, relying only on a single mechanical crushing or heating melting method, and are unable to cope with ice of different types and thicknesses. When encountering thicker or harder ice layers, the deicing effect is greatly reduced, and it is difficult to completely remove the ice, resulting in safety hazards on the transmission lines. Some devices do not fully consider the diversity of transmission lines in their design, and have poor adaptability to transmission lines of different specifications, materials and installation environments, and cannot be widely used in various power transmission scenarios. Some devices have complex structures, large volumes, and cumbersome installation and operation processes. They require professionals to use specialized equipment to operate them, which not only increases the time and labor costs of deicing operations, but also reduces work efficiency. In emergency situations, it is impossible to respond quickly to deicing work, further aggravating the scope and duration of the power outage. Therefore, an efficient, universal, and easy-to-operate deicing device for power transmission lines is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ice removal device for power transmission lines to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an ice removal device for a power transmission line, comprising a fixed plate, two side plates symmetrically installed at the bottom of one end of the fixed plate, a movable mechanism installed between the two side plates, a clamping mechanism provided at the bottom of the movable mechanism, a bracket welded to the bottom of the other end of the fixed plate, a cleaning assembly rotatably installed on the bracket, a driving assembly engaged with one side of the cleaning assembly, a heater provided on one side of the driving assembly, a heating head connected to the bottom of the heater, an ice-breaking assembly provided on one side of the heater, and the ice-breaking assembly connected to a pushing assembly.

[0007] By placing the device on the transmission line, then installing the clamping mechanism and adjusting the position of the clamping mechanism, the clamping mechanism and the moving mechanism can cooperate to clamp and fix the transmission line, and at the same time the transmission line is placed in the heating head. During the ice removal operation, the moving mechanism is operated to drive the entire device to move on the transmission line, and the front driving component drives the cleaning component to rotate, so that the cleaning component can remove the snow accumulated on the conveyor line. As the heater runs, the heating head heats the surface of the transmission line, so that the ice strips on the transmission line are melted, making the ice more brittle and reducing the bonding force between the ice and the transmission line. As the pushing component runs, the ice-breaking component cyclically clamps the surface of the transmission line back and forth. The ice is held and a collision is generated, so that the ice with reduced binding force to the transmission line can be broken more easily, thereby detaching from the transmission line, and as the device advances, the moving mechanism cooperates with the clamping mechanism to squeeze out the remaining ice on the transmission line, thereby completing the de-icing process of the transmission line. The entire de-icing process can reduce the load on the transmission line by removing the covering snow, and at the same time, the ice bound to the transmission line can be leaked out. As the leaked ice is heated and melted, the binding force between the ice and the transmission line is reduced, thereby reducing the hardness of the ice and making it easier to break. Subsequently, cyclic extrusion and crushing are carried out, so that the ice with lower hardness and lower binding force to the transmission line can be quickly broken after collision and extrusion, and detached from the transmission line, thereby improving the de-icing efficiency.

[0008] Preferably, the moving mechanism includes a first motor, a rotating rod, a driving wheel, a driving pulley, a follower rod, a follower wheel, a follower pulley and a synchronous belt. The first motor is installed on the outside of a side plate, and the output end of the first motor is connected to the rotating rod. The driving wheel is coaxially fixed on the rotating rod, and the driving pulley is installed at one end of the rotating rod. The follower rod is rotatably connected to the two side plates, and the follower wheel is coaxially fixed on the follower rod. The follower pulley is coaxially installed on the end of the follower rod, and the follower pulley and the driving pulley are connected by a synchronous belt.

[0009] Preferably, a plurality of notches are provided at the bottom of the side panel, and the clamping mechanism is connected and fixed to the side panel via the notches.

[0010] Preferably, the clamping mechanism includes a bolt rod, a splint, a nut, a support rod and a clamping wheel. Both ends of the bolt rod are sleeved with a splint, and each of the splints is supported against the side plate by a nut. Both sides of the bolt rod are provided with a support rod rotatably mounted on the two splints, and a clamping wheel is installed on each of the support rods. The bolt rod and the two support rods are slidably set in the corresponding slots.

[0011] Preferably, the cleaning assembly includes a shaft, a fixed ring, bristles and a follower gear. The shaft is rotatably mounted on the bracket. A fixed ring is coaxially fixed to the shaft. Bristles are provided on the outer surface of the fixed ring. A follower gear is coaxially provided at one end of the shaft and is meshed with the bottom of the drive assembly.

[0012] Preferably, the driving assembly includes a second motor, a driving rod and a driving gear. The second motor is mounted on a fixed plate. The output end of the second motor is connected to the driving rod. The bottom of the driving rod is coaxially fixed with a driving gear. The driving gear is meshed with the follower gear, and both the driving gear and the follower gear are bevel gears.

[0013] Preferably, the ice breaking assembly includes a slide rail, a slider, a fixed rod and a crushing wheel. There are two slide rails, and two sliders are symmetrically arranged on the two slide rails. A fixed rod is installed on each slider, and a crushing wheel is rotatably installed at the bottom end of each fixed rod.

[0014] Preferably, a sliding groove is provided on the fixing plate between the two sliding rails, and the fixing rod is slidably connected to the sliding groove.

[0015] Preferably, a fixed block is welded to one side of the sliding block, a connecting shaft is vertically welded to the fixed block, and the connecting shaft is hinged to one end of the pushing assembly.

[0016] Preferably, the pushing assembly includes an electric push rod, a connecting block, a pin shaft and a support beam. The electric push rod is installed on a fixed plate. A connecting block is installed at the telescopic end of the electric push rod. A pin shaft is vertically welded on the connecting block. The pin shaft is hinged to one end of the two support beams, and the other end of each support beam is hinged to the corresponding connecting shaft.

[0017] Technical effects and advantages of the present invention: 1. The cleaning assembly removes accumulated snow from power lines, reducing the load and exposing any ice that adheres to them for easier handling. The heater's heating head heats the surface of the power lines, melting the ice and reducing its hardness and the strength of its bond to the power lines. Driven by the pushing assembly, the ice-breaking assembly cyclically clamps and impacts the power lines, making the ice, which has reduced hardness and weakened its bond, easier to break. Finally, the moving mechanism cooperates with the clamping mechanism to squeeze out any remaining ice. The entire process is seamless and efficient, significantly improving ice removal efficiency.

[0018] 2. Through the coordination of bolt rods, clamping plates, nuts and other components, the height of the clamping wheel can be adjusted according to the size of the transmission line, ensuring that the device can move stably along transmission lines of different specifications and has a wide range of applicability to different transmission lines.

[0019] 3. The two crushing wheels can move closer to or farther away from each other under the drive of the electric push rod. When they move closer, they clamp and collide with the transmission line to break the ice. When they move away, the broken ice falls easily and the ice on the next section of the transmission line in the moving direction can be continued to be crushed, thus achieving continuous operation and ensuring the efficient de-icing work.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] As attached Figure 1-7 The power transmission line ice removal device shown includes a fixed plate 1, two side plates 2 are symmetrically installed at the bottom of one end of the fixed plate 1, a moving mechanism 3 is installed between the two side plates 2, and a clamping mechanism 4 is provided at the bottom of the moving mechanism 3. A bracket 5 is welded to the bottom of the other end of the fixed plate 1, and a cleaning component 6 is rotatably installed on the bracket 5. One side of the cleaning component 6 is engaged with a driving component 7, and one side of the driving component 7 is provided with a heater 8, and the bottom end of the heater 8 is connected to a heating head 9, and one side of the heater 8 is provided with an ice-breaking component 10, and the ice-breaking component 10 is connected to a pushing component 11.

[0030] During the specific implementation, the device is placed on the transmission line, and then the clamping mechanism 4 is installed and the position of the clamping mechanism 4 is adjusted so that the clamping mechanism 4 cooperates with the moving mechanism 3 to clamp and fix the transmission line, and at the same time the transmission line is placed in the heating head 9. During the ice removal operation, the moving mechanism 3 is operated to drive the entire device to move on the transmission line, and the driving component 7 in the front drives the cleaning component 6 to rotate, so that the cleaning component 6 clears the snow accumulated on the transmission line. As the heater 8 is running, the heating head 9 heats the surface of the transmission line, so that the ice on the transmission line is melted, making the ice more brittle and reducing the bonding force between the ice and the transmission line. As the pushing component 11 is running, the ice-breaking component 10 circulates the transmission line. The surface of the wire is clamped back and forth to produce collisions, so that the ice with reduced binding force to the transmission line can be broken more easily and thus detached from the transmission line. As the device advances, the moving mechanism 3 cooperates with the clamping mechanism 4 to squeeze out the remaining ice on the transmission line, thereby completing the de-icing process of the transmission line. The entire de-icing process can reduce the load on the transmission line by clearing the covering snow, and at the same time can leak out the ice bound to the transmission line. As the leaked ice is heated and melted, the binding force between the ice and the transmission line is reduced, thereby reducing the hardness of the ice and making it easier to break. Subsequently, cyclic extrusion and crushing are carried out, so that the ice with lower hardness and lower binding force to the transmission line can be quickly broken after collision and extrusion, and detached from the transmission line, thereby improving the de-icing efficiency.

[0031] The moving mechanism 3 includes a first motor 301, a rotating rod 302, a driving wheel 303, a driving pulley 304, a follower rod 305, a follower wheel 306, a follower pulley 307 and a synchronous belt 308. The first motor 301 is installed on the outside of a side plate 2. The output end of the first motor 301 is connected to the rotating rod 302. The driving wheel 303 is coaxially fixed on the rotating rod 302. The driving pulley 304 is installed at one end of the rotating rod 302. The follower rod 305 is rotatably connected to the two side plates 2. The follower wheel 306 is coaxially fixed on the follower rod 305. The follower pulley 307 is coaxially installed on the end of the follower rod 305. The follower pulley 307 and the driving pulley 304 are connected by a synchronous belt 308.

[0032] During specific implementation, the first motor 301 is operated to cause the rotating rod 302 to rotate, thereby driving the driving wheel 303 and the driving pulley 304 to rotate synchronously, and under the connection of the synchronous belt 308, the follower pulley 307 drives the follower rod 305 to rotate, so that the follower wheel 306 can rotate synchronously with the driving wheel 303, so that the bottom clamping mechanism 4 cooperates with the clamping of the transmission line, so that the driving wheel 303 and the follower wheel 306 move along the transmission line, so that the entire device can move along the transmission line, so as to perform de-icing operations on the entire transmission line.

[0033] The bottom of the side plate 2 is provided with a plurality of notches, and the clamping mechanism 4 is connected and fixed to the side plate 2 through the notches.

[0034] The clamping mechanism 4 includes a bolt rod 401, a splint 402, a nut 403, a support rod 404 and a clamping wheel 405. Both ends of the bolt rod 401 are sleeved with a splint 402, and each splint 402 is pressed against the side plate 2 by a nut 403. Both sides of the bolt rod 401 are provided with a support rod 404 rotatably mounted on the two splints 402, and each support rod 404 is installed with a clamping wheel 405. The bolt rod 401 and the two support rods 404 are all slidably set in the corresponding slots.

[0035] During specific implementation, the bolt rod 401 and the support rod 404 are slid upward through the corresponding slots, and then the height of the two clamping wheels 405 are adjusted according to the position of the transmission line, so that the two clamping wheels 405 and the driving wheel 303 and the follower wheel 306 clamp the transmission line, and then the nut 403 is tightened to fix the clamping position, so that the clamping can be adjusted according to the size of the transmission line, ensuring that the device can move along the transmission line when the moving mechanism 3 is in operation.

[0036] The cleaning assembly 6 includes a shaft 601, a fixed ring 602, bristles 603 and a follower gear 604. The shaft 601 is rotatably mounted on the bracket 5. A fixed ring 602 is coaxially fixed to the shaft 601. Bristles 603 are provided on the outer surface of the fixed ring 602. A follower gear 604 that is meshed with the bottom of the driving assembly 7 is coaxially provided at one end of the shaft 601.

[0037] The driving assembly 7 includes a second motor 701, a driving rod 702 and a driving gear 703. The second motor 701 is installed on the fixed plate 1. The output end of the second motor 701 is connected to the driving rod 702. The bottom of the driving rod 702 is coaxially fixed with a driving gear 703. The driving gear 703 is meshed with the follower gear 604, and both the driving gear 703 and the follower gear 604 are bevel gears.

[0038] During specific implementation, the second motor 701 is operated to cause the driving rod 702 to drive the driving gear 703 to rotate, thereby engaging the follower gear 604 to rotate, so that the shaft 601 drives the fixing ring 602 to rotate, so that the bristles 603 clean the snow on the surface of the transmission line as it rotates, thereby leaking the ice attached to the transmission line and removing the snow in advance, reducing the load on the transmission line, and facilitating the subsequent heating of the ice, reducing the hardness of the ice and the bonding force between the ice and the transmission line.

[0039] The ice breaking assembly 10 includes a slide rail 1001, a slider 1002, a fixed rod 1003 and a crushing wheel 1004. There are two slide rails 1001, and two sliders 1002 are symmetrically arranged on the two slide rails 1001. A fixed rod 1003 is installed on each slider 1002, and a crushing wheel 1004 is rotatably installed at the bottom end of each fixed rod 1003.

[0040] A sliding groove is provided on the fixing plate 1 between the two sliding rails 1001 , and the fixing rod 1003 is slidably connected to the sliding groove.

[0041] A fixing block 12 is welded to one side of the slider 1002 , and a connecting shaft 13 is vertically welded to the fixing block 12 . The connecting shaft 13 is hinged to one end of the pushing assembly 11 .

The pin 1103 is hinged to one end of the two support beams 1104, and the other end of each support beam 1104 is hinged to the corresponding connecting shaft 13.

[0043] During specific implementation, the electric push rod 1101 is extended and retracted, so that the connecting block 1102 can push and pull the two support beams 1104 hinged to the pin shaft 1103, so that under the connection of the connecting shaft 13, the two sliders 1002 can approach or move away from each other along the slide rail 1001, so that the crushing wheels 1004 rotatably installed at the bottom end of the fixed rod 1003 can approach or move away from each other. When the two crushing wheels 1004 approach each other, they can clamp and collide with the transmission line, so that the ice on the transmission line is broken and detached. After the two crushing wheels 1004 move away from each other, the crushed ice can be easily dropped, and at the same time, the ice on the transmission line in the moving direction can be continued to be crushed, thereby forming a continuous operation and improving the efficiency of ice breaking.
