Description

Technical Field

[0001] This utility model relates to a de-icing device for overhead power lines, and pertains to the field of overhead line operation and maintenance technology. Background Technology

[0002] Overhead power lines are a crucial component of power systems for transmitting and distributing electrical energy. They typically consist of conductors, towers, insulators, and hardware, and are erected in the air, spanning long distances to transmit electricity generated by power plants to substations in various locations, from where it is distributed to end users. During icy and snowy weather, ice can form on the surface of overhead power lines. As the ice layer thickens, it increases the weight of the overhead power lines, thereby increasing their safety. Therefore, it is necessary to remove the ice layer from overhead power lines promptly. Current removal methods mostly involve manual removal or the use of drones. CN104104048B discloses a de-icing device that uses an electromagnetic vibrator to vibrate and tap the ice on a linear object. However, this method of removing ice by vibrating and tapping the linear object with an electromagnetic vibrator can only remove ice attached to the side of the high-voltage overhead line that is being tapped, resulting in insufficient de-icing effectiveness. Utility Model Content

[0003] The purpose of this utility model is to design a power overhead line de-icing device that improves the de-icing effect of overhead lines.

[0004] This utility model includes a frame with openings at both ends. Two sets of left and right traveling positioning wheels are installed within the frame, and an ice-breaking mechanism is positioned between these two sets of traveling positioning wheels. The ice-breaking mechanism includes an ice-breaking sleeve fixed to the frame. Ice-breaking spikes are installed in the inner hole of the ice-breaking sleeve. The diameter of the circle formed by the inner ends of each ice-breaking spike is larger than the diameter of the circle formed by the inner ends of the traveling positioning wheels in the left and right traveling positioning wheel sets. A miniature vibration motor is also connected to the frame via a spring. A power supply and switch electrically connected to the miniature vibration motor are located at the bottom of the frame. This design allows the ice layer around the cable to be broken by the ice-breaking spikes within the ice-breaking sleeve. The larger diameter of the circle formed by the inner ends of each ice-breaking spike avoids damage to the cable surface. The broken ice layer is then detached from the cable by the miniature vibration motor.

[0005] Furthermore, a support wheel assembly is provided in the middle of the ice-breaking sleeve. The diameter of the circle formed by the inner ends of the support wheel assembly is adapted to the diameter of the circle formed by the inner ends of the travel positioning wheels in the left and right travel positioning wheel assemblies. The support wheel assembly configured in this manner can prevent the cable from swinging in the ice-breaking sleeve and avoid damage to the cable surface by ice-breaking spikes.

[0006] Furthermore, the ice-breaking sleeve consists of a sleeve and ice-breaking spikes inside the sleeve, and a heating mechanism connected to a power source is installed inside the ice-breaking sleeve. This heating mechanism melts the ice layer as the ice-breaking spikes break it, thinning the ice layer and improving the breaking effect.

[0007] Furthermore, the sleeve of the ice-breaking sleeve is composed of two semi-circular parts, and ice-breaking spikes are respectively provided on the inner surface of each semi-circular part. The two semi-circular parts are respectively fixedly connected to the frame by support rods.

[0008] Furthermore, stabilizing wings are installed on both sides of the frame.

[0009] Furthermore, the stabilizer wings tilt downwards from the frame, and each stabilizer wing is equipped with a solar panel connected to a power source. This downward-tilting stabilizer wing design prevents the frame from twisting or tilting when moving along the cables, and the solar panels eliminate the need for battery replacements, saving manpower and resources.

[0010] This invention includes an ice-breaking mechanism that can cut and break the ice layer on the surface of the cable using ice-breaking spikes. At the same time, it works in conjunction with a heating mechanism inside the ice-breaking sleeve to heat the ice layer, thereby improving the efficiency of ice breaking.

[0011] This utility model is equipped with two clappers that are fitted with miniature vibration motors. After the miniature vibration motors are activated, they can beat the broken ice layer, causing the ice layer to fall off. Attached Figure Description

[0019] by Figure 1 Define the up, down, left, right, front, and back directions in this embodiment.

[0020] As shown in the figure, this embodiment includes a frame 1, which is open at both the front and rear ends and is composed of two semi-circular arc plates, which are fixedly connected by bolts. In this embodiment, the end closest to the center of the frame 1 is defined as the inner end. A left travel positioning wheel set 2 and a right travel positioning wheel set 3 are respectively provided at the left and right ends of the frame 1. Each travel positioning wheel set consists of two travel positioning wheels symmetrically arranged vertically. Each travel positioning wheel is mounted in the inner cavity of the frame 1 via a rotatable connecting base 4. The diameter of the circle formed by the inner ends of each travel positioning wheel is adapted to the diameter of the cable 18, providing support. In this embodiment, a reduction motor 19 is provided on the travel positioning wheel at the lower part of the left travel positioning wheel set 2. During use, starting the reduction motor 19 allows the frame 1 to move along the cable 18.

[0021] An ice-breaking mechanism is installed between the left and right travel positioning wheel sets 2 and 3. This mechanism includes an ice-breaking sleeve 5, which consists of a sleeve and ice-breaking spikes 7 inside the sleeve. The sleeve of the ice-breaking sleeve 5 is composed of two semi-circular parts, each fixedly installed in the inner cavity of the frame 1 by a support rod 6. A set of ice-breaking spikes 7 is provided on the inner surface of each of the two semi-circular parts of the ice-breaking sleeve 5. The diameter of the circle formed by the inner ends of each ice-breaking spike 7 is larger than the diameter of the circle formed by the inner ends of the travel positioning wheels in the left and right travel positioning wheel sets 2 and 3. During use, the ice-breaking spikes 7 can cut and break the ice layer around the cable 18 while avoiding damage to the outer surface of the cable 18. Heating mechanisms 9 are provided in the two semi-circular parts of the ice-breaking sleeve 5, which can melt the ice layer when the ice-breaking spikes 7 break it, improving the ice-breaking effect. A support wheel assembly 8 is located in the middle of the ice-breaking sleeve 5. In this embodiment, the support wheel assembly 8 has four support wheels symmetrically arranged vertically. The diameter of the circle formed by the inner ends of each support wheel is compatible with the diameter of the circle formed by the inner ends of each travel positioning wheel in the left travel positioning wheel assembly 2 and the right travel positioning wheel assembly 3. During the movement of the frame 1 along the cable 18, the support wheel assembly 8 can support the cable 18, preventing the cable 18 from swinging in the ice-breaking sleeve 5 and avoiding damage to the surface of the cable 18 by the ice-breaking spikes 7.

[0022] A miniature vibration motor 12 is provided on the left side of the ice-breaking mechanism. In this embodiment, two miniature vibration motors 12 are provided. Each miniature vibration motor 12 is installed in the inner cavity of the frame 1 by a spring 11. A beater 10 is fixedly installed on the inner end of the two miniature vibration motors 12. The beater 10 is a semi-circular arc plate with a size that matches the diameter of the cable 18. When in use, starting the miniature vibration motor 12 can beat the broken ice layer by the rebound force of the spring 11, causing the ice layer to fall off the surface of the cable.

[0023] A power supply compartment 13 is located at the lower end of the frame 1, and the upper end of the power supply compartment 13 is fixedly connected to the frame 1. A circuit board is installed inside the compartment, and a power supply 14 is installed on the right end of the circuit board. In this embodiment, the heating mechanism 9, the micro vibration motor 12, and the geared motor 19 are electrically connected to the power supply 14 via lines, and the power supply 14 can control the start and stop of each component. A switch 15 is located on the left side of the power supply 14, and the switch 15 is electrically connected to the power supply 14 and connected to the geared motor 19 via a line, which can control the forward and reverse rotation of the geared motor 19, thereby controlling the frame 1 to move left and right along the cable 18. A signal transmitter is installed on the circuit board, which can remotely control the power supply 14 and the switch 15. The signal transmitter in this utility model adopts existing technology, which will not be described in detail here.

[0024] The frame 1 has balancing wings 16 on both the front and rear sides. The upper end of each balancing wing 16 is fixedly connected to the frame 1, and it tilts downward from the connection point. When the frame 1 moves along the cable 18, the balancing wings 16 can prevent the frame 1 from twisting or tilting. The upper surface of the balancing wings 16 is equipped with solar panels 17, which are connected to the power supply 14 through wires, and can charge the power supply 14, eliminating the need to replace the power supply and saving energy and protecting the environment.

[0025] In this embodiment, the power supply 14 is first controlled to activate the heating mechanism 9, the micro vibration motor 12, and the reduction motor 19. After the reduction motor 19 starts, the frame 1 moves to the right along the cable 18. During this movement, the ice-breaking spikes 7 cut and break the ice layer around the cable 18. After the heating mechanism 9 starts, it melts the ice layer as the ice-breaking spikes 7 break it, making the ice layer thinner and improving the breaking effect of the ice-breaking spikes 7. After the micro vibration motor 12 starts, it causes the beater 10 to vibrate. The rebound force of the spring 11 enhances the vibration effect of the beater 10, striking the broken ice layer and causing it to fall off the surface of the cable 18. In application, the frame 1 can be moved back and forth along the cable 18 by the switch 15 according to the actual situation to ensure the de-icing effect.
