Description

Technical Field

[0001] The present application belongs to the technical field of power transmission line deicing, and specifically relates to a power transmission line deicing device. Background Art

[0002] Icing on transmission lines is a complex and diverse problem, characterized by diverse ice types (such as rime and rime), complex formation conditions (requiring low temperatures and high humidity), and uneven distribution. Icing can lead to mechanical degradation of conductors and towers, such as increased loads, galloping, and fatigue damage; reduced insulation performance, such as insulator flashover and poor conductivity; and operational and maintenance difficulties, including increased repair costs, communication disruptions, and even power outages.

[0003] Current de-icing technologies for transmission lines primarily include mechanical de-icing, AC short-circuit current de-icing, DC short-circuit de-icing, natural de-icing, and emerging technologies such as electromagnetic pulse de-icing and de-icing with low-Curie-point materials. While mechanical de-icing methods, such as manual hammering and helicopter de-icing, are simple and easy to implement, they suffer from safety and efficiency issues. AC short-circuit current de-icing is convenient and low-cost, but requires a power outage and places certain demands on grid stability. DC short-circuit de-icing offers better de-icing effectiveness, but mobile equipment is expensive and fixed equipment lacks flexibility. Furthermore, natural de-icing relies on natural forces, is unpredictable, and cannot promptly remove ice. While emerging technologies such as electromagnetic pulse de-icing and de-icing with low-Curie-point materials offer certain theoretical advantages, they suffer from limited de-icing coverage and high energy consumption. Overall, existing de-icing methods still have shortcomings in terms of safety, efficiency, cost, applicability, and environmental impact. This is particularly true in complex meteorological and topographical conditions, where a universal and efficient de-icing technology is lacking.

[0004] Therefore, a transmission line deicing device is designed to better solve the problem of transmission line icing. Summary of the Invention

[0007] Optionally, the striking assembly includes a first transmission member, a first spring sleeved on the outer circumference of the first transmission member, and a hammer head connected to one end of the first transmission member.

[0014] Optionally, the on-line walking trolley includes two shells, two driving mechanisms respectively arranged on the two shells, and a mounting frame for installing a striking de-icing mechanism. The two shells are fixedly connected to the mounting frame. Each of the driving mechanisms includes a driving motor arranged in the shell, a transmission assembly connected to the output shaft of the driving motor, and a pulley assembly connected to the transmission assembly. The pulley assembly is fixedly rotated on the shell for rolling cooperation with the power transmission line.

[0015] Optionally, the transmission assembly includes a driving pulley connected to the output shaft of the driving motor, two driven pulleys rotatably arranged on the housing, and a transmission belt for transmitting the driving pulley and the two driven pulleys.

[0019] The beneficial effect of this application is that the mechanical energy output by the reciprocating linear motion assembly drives the striking assembly to reciprocate and repeatedly impact the power transmission line.

The on-line trolley moves along the power transmission line, achieving the effect of de-icing while moving, thereby improving de-icing efficiency. Because the striking assembly is elastically mounted on the mounting base, it does not need to be fixedly connected to the actuator end of the reciprocating linear motion assembly, simplifying the connection structure and reducing manufacturing difficulty.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] like Figure 1-9 As shown, the present application provides a transmission line de-icing device, comprising: an online walking trolley 100 and a striking de-icing mechanism 200; wherein, the online walking trolley 100 is used to move along the transmission line 1.1; the striking de-icing mechanism 200 is arranged on the online walking trolley 100, and the striking de-icing mechanism 200 includes a mounting seat 210, a reciprocating linear motion component 220 arranged on the mounting seat 210, and a striking component 230 elastically arranged at the end of the mounting seat 210, the reciprocating linear motion component 220 elastically abuts against the striking component 230, and the reciprocating linear motion component 220 moves to cause the striking component 230 to move until it hits the transmission line 1.1, and the striking component 230 is reset under the action of its own elastic force.

[0024] Compared to the prior art, the power transmission line deicing device provided by the present application uses the mechanical energy output by the reciprocating linear motion component 220 to drive the striking component 230 to perform reciprocating motion and repeatedly impact the power transmission line 1.1. The kinetic energy generated causes the ice covering the power transmission line 1.1 to break and fall off. Moreover, the impact can cause the kinetic energy to act on the ice instantly, making it easier to break the ice covering compared to the existing scraping and vibration methods. The on-line walking trolley 100 moves along the power transmission line 1.1, achieving the effect of deicing while moving, thereby improving the deicing efficiency. Since the striking component 230 is elastically mounted on the mounting base 210, the striking component 230 does not need to be fixedly connected to the execution end of the reciprocating linear motion component 220, which simplifies the connection structure and reduces the manufacturing difficulty.

[0025] In one possible implementation, Figure 3 and Figure 4 As shown, the striking assembly 230 includes a first transmission member 231, a first spring 232 sleeved on the outer circumference of the first transmission member 231, and a hammer head 233 connected to one end of the first transmission member 231. The reciprocating linear motion assembly 220 pushes the first transmission member 231 and compresses the first spring 232 so that the hammer head 233 hits the transmission line 1.1. The first spring 232 is used to reset the first transmission member 231 when the executing end of the reciprocating linear motion assembly 220 retracts.

[0026] Specifically, the reciprocating linear motion component 220 pushes the first transmission member 231 downward to drive the hammer head 233 and compresses the first spring 232 until the hammer head 233 hits the ice on the surface of the transmission line 1.1. Then the execution end of the reciprocating linear motion component 220 contracts, and the first transmission member 231 and the hammer head 233 are reset under the action of the first spring 232, completing a cycle of hitting the ice, and this is repeated.

[0027] In one possible implementation, the first transmission member 231 has a hollow structure, and the striking assembly 230 also includes a second spring 234 arranged in the hollow structure and two sliders 235 respectively arranged at both ends of the second spring 234. The execution end portion of the reciprocating linear motion assembly 220 extends into the hollow structure and abuts against one of the sliders 235. The elastic force of the second spring 234 is less than the elastic force of the first spring 232.

[0028] Specifically, the executing end of the reciprocating linear motion assembly 220 moves, and a protruding part of the executing end extends into the first transmission member 231, pushing the slider 235 to move downward. At this time, the second spring 234 is squeezed, and the other parts of the executing end are in contact with the first transmission member 231. (Under the action of the slider 235, the energy stored inside the first transmission member 231 will produce a downward force, which will be released after the hammer head 233 hits) As the executing end gradually moves, it drives the first transmission member 231 to move downward. At this time, the first spring 232 is squeezed, and the first transmission member 231 drives the hammer head 233 to complete the hitting. At this time, the ice on the line surface is cleared, and under the action of the first spring 232, the first transmission member 231 drives the hammer head 233 to rebound to its initial state. The online walking trolley 100 makes the de-icing device move along the transmission line 1.1, and repeatedly performs the above-mentioned hammering action to completely clear the ice layer on the entire line. Because the rebound force of the first spring 232 is always greater than that of the second spring 234, the hammer head 233 will generate some vibration at the moment of reset. This is converted into a momentary upward movement of the upper slider 235, effectively offsetting the vibration caused by the reverse rebound, thereby ensuring that the device is always stably suspended on the transmission line 1.1 and moves at a constant speed. In addition, the hammer head 233 also moves during contact with the ice layer. The design of the second spring 234 allows the hammer head 233 to automatically adapt to changes in the thickness of the ice layer, thereby moving along the line while hammering the ice without interfering with each other. This effectively avoids the problem of movement obstruction of the deicing device caused by the hammer head 233 scratching the line surface.

[0029] In one possible implementation, Figure 4 As shown, the hammer head 233 has a hollow structure 2331, and a plurality of stacked shock-absorbing plates 236 are disposed within the hollow structure 2331. When the hammer head 233 strikes the ice layer, the shock-absorbing plates 236 disposed inside the hammer head 233 move upward. This design is to prevent vibration generated by the hammering moment, which would affect the deicing effect, and to achieve the best hammering effect.

[0030] In one possible implementation, the impact surface of the hammer head 233 is a sphere, an ellipsoid, or a parabola, so that the contact area between the hammer head 233 and the ice layer is small, thereby providing a deicing effect and reducing damage to the transmission line 1.1.

[0031] In one possible implementation, Figure 4 and Figure 8 As shown, the reciprocating linear motion assembly 220 includes a de-icing motor 221, a cylindrical cam 222 connected to the output shaft of the de-icing motor 221, and a second transmission member 223 that cooperates with the cylindrical cam 222. A guide structure is provided in the mounting seat 210 for guiding the second transmission member 223 to move along a straight line.

[0032] Specifically, the de-icing motor 221 can be a servo motor, a stepper motor or a reduction motor. The de-icing motor 221 starts to drive the cylindrical cam 222 to rotate. Under the transmission action of the second transmission member 223, the rotational mechanical energy is converted into linear motion mechanical energy, thereby driving the striking component 230 to complete the action of striking the ice layer. The striking frequency can be controlled by the speed of the output shaft of the de-icing motor 221. Compared with similar equipment such as electric push rod machines, the striking frequency is higher.

[0033] In one possible implementation, a push rod 224 is provided at one end of the second transmission member 223 away from the de-icing motor 221 . The push rod 224 is used to extend into the hollow structure and abut against the slider 235 . The end face of the second transmission member 223 is used to abut against the first transmission member 231 .

[0034] Specifically, if Figure 4 As shown, the push rod 224 is arranged at the center position of the bottom end of the second transmission member 223 and is integrally formed. After the de-icing motor 221 is started, it drives the cylindrical cam 222 to move, thereby driving the second transmission member 223 to move and gradually move downward, driving the push rod 224 to move downward, and the push rod 224 extends into the interior of the first transmission member 231 (the end surface thickness of the first transmission member 231 can effectively play a guiding and stabilizing role to ensure that the push rod 224 extends vertically and effectively), and moves downward against the upper slider 235. At this time, the second spring 234 is squeezed until the bottom end surface of the second transmission member 223 abuts against the upper end surface of the first transmission member 231. (Under the action of the slider 235, the first transmission member 231 stores energy inside, which will generate a downward force, which will be released after the hammer head 233 hits) As the second transmission member 223 gradually moves, the first transmission member 231 is pushed to move downward. At this time, the first spring 232 is squeezed, and the first transmission member 231 drives the hammer head 233 downward to complete the hitting. At this time, the ice on the surface of the line is cleared. Under the action of the first spring 232, the first transmission member 231 drives the hammer head 233 to rebound to its initial state. The online walking trolley 100 moves the de-icing device along the transmission line 1.1, and repeatedly performs the above-mentioned hammering action to completely clear the ice layer on the entire line.

[0035] In one possible implementation, Figure 6-8 As shown, the guide structure includes a guide plate 226 arranged on the outer periphery of the second transmission member 223 and a guide rail groove 211 arranged on the inner wall of the mounting seat 210 , and the guide plate 226 and the guide rail groove 211 are embedded and slidably matched.

[0036] Specifically, the de-icing motor 221 is connected to the cylindrical cam 222 through a coupling. When the cylindrical cam 222 rotates, the roller 225 provided on the second transmission member 223 is embedded in the groove 2221 of the cylindrical cam 222, converting the rotation of the cylindrical cam 222 into a linear reciprocating motion of the second transmission member 223, and then driving the striking assembly 230 to complete the action of striking the ice layer.

[0037] In one possible implementation, Figure 2-Figure 4 As shown, the online walking trolley 100 includes two shells 110, two driving mechanisms 120 respectively arranged on the two shells 110, and a mounting frame 130 for installing the striking de-icing mechanism 200. The two shells 110 are fixedly connected to the mounting frame 130. Each driving mechanism 120 includes a driving motor 121 arranged in the shell 110, a transmission assembly 122 connected to the output shaft of the driving motor 121, and a pulley assembly 123 connected to the transmission assembly 122. The pulley assembly 123 is fixedly rotatably arranged on the shell 110 for rolling cooperation with the transmission line 1.1.

[0038] Specifically, power line 1.1 is positioned between two housings 110. A traveling trolley 100 is mounted on power line 1.1 via multiple pulley assemblies 123. A drive motor 121 drives pulley assemblies 123 via a transmission belt 1223 of a transmission assembly 122, thereby moving along power line 1.1. A mounting bracket 130 is located at the front of traveling trolley 100, crushing ice in front of it and making it easier for traveling trolley 100 to pass.

[0039] In this embodiment, the driving motor 121 may be a servo motor, a stepping motor or a reduction motor.

[0040] In one possible implementation, Figure 5 and Figure 9 As shown, the transmission assembly 122 includes a driving pulley 1221 connected to the output shaft of the driving motor 121, two passive pulleys 1222 fixedly arranged on the housing 110, and a transmission belt 1223 for transmitting the driving pulley 1221 and the two passive pulleys 1222. Each driving mechanism 120 includes at least two pulley assemblies 123, which are respectively matched with the two passive pulleys 1222 for transmission; the pulley assembly 123 includes a semi-structural pulley 1231, a wheel shaft 1232 connected to one side of the semi-structural pulley 1231, a positioning sleeve 1233 linearly slidingly sleeved on the outer periphery of the wheel shaft 1232, and an elastic member 1235 arranged in the positioning sleeve 1233 and located at one end of the wheel shaft 1232. The positioning sleeve 1233 is rotatably connected to the housing 110 through a bearing 1234, and the passive pulley 1222 is fixedly connected to the positioning sleeve 1233. The semi-structural pulleys 1231 in the two driving mechanisms 120 are symmetrically arranged.

[0041] Specifically, the two driving mechanisms 120 are in a symmetrical relationship, and the two driving motors 121 respectively drive the two active pulleys 1221, which respectively drive the two transmission belts 1223 to run so that the four passive pulleys 1222 rotate synchronously, and then the four semi-structure pulleys 1231 rotate synchronously. The four semi-structure pulleys 1231 are symmetrically arranged in pairs. The semi-structure pulley 1231 is equivalent to a conventional pulley cut into one of the two symmetrical halves from the middle radially, which is equivalent to forming two pulleys. In the natural state, the width of the wheel groove of the two pulleys is smaller than the diameter of the transmission line 1.1. When the pulley contacts the cable, under the action of gravity, the wheel axle 1232 moves axially to compress the elastic part 1235, and the two wheel discs of the pulley open outward, exerting a certain clamping force on the transmission line 1.1, thereby ensuring that the de-icing device moves stably on the transmission line 1.1, and cooperates with the shell 110 structure to extend downward by a certain distance to lower the overall center of gravity of the de-icing device, thereby further improving the movement stability. The pulley assembly 123 provided in the present application only requires a plurality of pulleys arranged in a straight line (consisting of two semi-structural pulleys 1231) and is placed above the transmission line 1.1. In this way, it can be directly hoisted to the position of the transmission line 1.1 to be de-iced by a hoisting device. After de-icing is completed, it can be directly transferred to the next de-icing point (passing through the line tower) by the hoisting device, or folded up, which greatly improves flexibility.

[0042] It should be noted that hoisting equipment includes drones and ground cranes. The surface of the semi-structural pulley 1231 that contacts the power transmission has an anti-slip structure or anti-slip rubber layer, which maintains sufficient friction during movement. This effectively avoids the problem of excessive or slow movement caused by insufficient friction, whether the device is climbing or descending a slope.

[0043] In this embodiment, the elastic member 1235 is a spring.

[0044] In one possible implementation, both driving pulley 1221 and driven pulley 1222 are synchronous pulleys, and transmission belt 1223 is a synchronous belt. The synchronous pulleys have tooth grooves (e.g., arc teeth, trapezoidal teeth, etc.) that match the tooth profile of the synchronous belt, meshing with the synchronous belt (toothed belt). The tooth profile ensures precise engagement and prevents slippage. Power is transmitted through the meshing of the belt teeth and the wheel teeth, resulting in a constant transmission ratio, allowing multiple pulleys to operate at the same speed, making it easier to move the de-icing device along power line 1.1.

[0045] In one possible implementation, the line walking trolley 100 further includes a hanger 140, the ends of which are respectively connected to the tops of the two housings 110. In this way, the hook of the drone is connected to the hanger 140 to hoist the deicing device to the location of the transmission line 1.1 to be deiced.

[0046] In one possible implementation, Figure 5As shown, housing 110 also houses a power module 150 for powering the on-line trolley 100 and the de-icing mechanism 200. This eliminates the need for an external power source and broadens the application range of the de-icing device. Power module 150 is located at the inner bottom of housing 110, lowering the center of gravity and improving stability on transmission line 1.1.

In line with the present application, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of different aspects of one or more embodiments of the present application as described above, which are not provided in detail for the sake of simplicity.
