[0002] Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are raised by supporting towers, while more transmission lines use bare wires.

[0003] In freezing rain and snow weather, the outer wall of the transmission line freezes, which increases the weight of the transmission line and easily causes

[0004] The collapse of iron towers and the breakage of transmission lines seriously affect the stable operation of the power grid. Therefore, it is necessary to clean the ice attached to the outer wall of the transmission line. However, the existing de-icing method for transmission lines mostly adopts the method of manual hammering. Due to the high height of the iron towers and the fact that most transmission lines are bare wires, the manual hammering method is very dangerous, with a large workload and low efficiency.

[0005] The utility model prepares a transmission line deicing device, which is installed by means of drone hoisting, and automatically de-ices a single section of the line, thereby improving efficiency and stability. Utility Model Content

[0009] The first belt pulley is matched with the second belt pulley through belt transmission. The second belt pulley is fixed on one end of the machine shaft, and a polarizing weight is fixed on the other end.

[0010] Furthermore, the roller side wall has a waist groove that matches the surface of the power transmission line, the waist groove axis corresponds to an arc-shaped axial section of the roller, the waist groove side wall has bar teeth, the bar teeth are evenly arranged around the roller axis, and the bar teeth are arc-shaped.

[0011] Furthermore, the suspension plate is provided with a support frame for supporting the motor, so as to ensure full contact between the motor and the suspension plate.

[0012] Furthermore, the side of the rotating shaft corresponding to the roller is provided with a limit baffle, the limit baffle is circular, and the rotating shaft passes through the center of the limit baffle and is vertically fixed.

[0013] Furthermore, a counterweight block is detachably mounted on the free end of the rotating shaft.

[0014] The utility model has the following beneficial effects: one end of the machine shaft cooperates with the first pulley through the transmission of the second pulley, so that the overall device can move on the transmission line, and the walking process is completed by rolling on the transmission line by the roller, and at the same time, the other end of the machine shaft is provided with a polarization hammer, and when the motor is running, the polarization hammer is driven to move eccentrically, so that the overall device can generate violent high-frequency vibration without affecting the moving process.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-2As shown: a transmission line deicing device, including a roller 1 for traveling on a transmission line, a first pulley 11 is arranged at the end side of the roller 1, the roller 1 is coaxially arranged with the first pulley 11, and an axial hole 12 is opened at the axis position, the roller and the end sides corresponding to the first pulley are fixed and form an integrated structure, a rotating shaft 4 is installed in the axial hole 12 for the roller to rotate, one end of the rotating shaft 4 is a free end, a notch for hanging, and high-altitude hanging installation is performed by drone or manual, and the free end is clamped into the transmission line, and a hanging plate 2 is fixed at the other end, the projection of the hanging plate corresponding to the traveling direction is an L-shaped structure, with side plates and a bottom plate, the side plates are used as suspension, the bottom plate is used to support the motor, the side plates and the bottom plate are fixed vertically and integrally, the upper side of the side plate is fixed vertically to the rotating shaft, a motor 3 is suspended on the hanging plate 2, and a second pulley 32 is installed on the shaft 31 of the motor 3;

[0022] The first pulley 11 and the second pulley 32 are matched through the belt 5 transmission, the second pulley 32 is fixed at one end of the shaft 31, and the polarizing weight 33 is fixed at the other end. The axis position of the motor is the shaft, and the second pulley is sleeved at the corresponding output end of the shaft. The first pulley and the second pulley correspond to each other on the vertical plane and are sleeved by the belt.

[0023] One end of the machine shaft cooperates with the first pulley through the transmission of the second pulley to realize the movement of the entire device on the transmission line, and the walking process is completed by rolling on the transmission line by the roller. At the same time, the other end of the machine shaft is provided with a polarization hammer. When the motor is running, it also drives the polarization hammer to move eccentrically, so that the entire device can vibrate violently at high frequency without affecting the moving process.

[0024] When the roller moves on the transmission line, on the one hand, the roller can break and separate the ice on the transmission line through friction, and on the other hand, the vibration can further promote the breaking of the ice, ultimately achieving the purpose of efficient ice removal.

The waist groove corresponds to the axial section of the roller 1 and is arc-shaped. The side wall of the waist groove has bar teeth 13. The bar teeth 13 are evenly arranged around the axis of the roller 1 and are arc-shaped. The waist groove can promote the roller to move more stably on the transmission line and prevent it from being unhooked. The bar teeth help to increase the friction between the roller and the transmission line, and are also used to crush ice on the transmission line.

[0026] The suspension plate 2 is provided with a support frame 21 for supporting the motor 3, which is used to make the motor 3 fully contact with the suspension plate 2. To improve the transmission of vibration, the support frame is a hollow structure, the part supporting the motor is an arc structure, and the hollow part is used to install the battery.

[0027] like Figure 2As shown: the side of the rotating shaft 4 corresponding to the roller 1 has a limit stopper 41, the limit stopper 41 is circular, and the rotating shaft 4 passes through the center of the limit stopper 41 and is fixed vertically, which is used to limit the position of the roller and keep it stable when the roller rotates.

[0028] The free end of the rotating shaft 4 is detachably mounted with a counterweight 42 for balancing so that the whole device can remain balanced when running on the transmission line.

[0029] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
