AI Technical Summary
In overhead transmission lines, snow easily accumulates at the vibration damper, increasing the load on the line and fittings and leading to the risk of line damage or pole collapse, especially in the windy and snowy weather of winter and spring in northern regions.
A smart snow removal and vibration damping hammer was designed, which combines a snow volume sensor, a vibration motor, a solar photovoltaic panel, an energy storage battery, and an inverter. The snow volume sensor detects the amount of snow and starts the vibration motor to shake off the snow. The hammer head consumes the vibration energy, and a solar power supply system provides power support.
It effectively prevents snow accumulation, reduces the risk of line damage, utilizes a solar power system to reduce maintenance costs, and uses hammers to scare away birds, dissipate vibration energy, and improve line stability.

Technical Field
[0001] This invention relates to the field of auxiliary equipment for power transmission lines, specifically to an intelligent de-icing and snow-removing vibration damper for power transmission lines. Background Art
[0002] In overhead transmission lines, wind can cause conductor vibration. If the conductor amplitude is too large or the vibration frequency causes tower resonance, there is a risk of tower collapse. Therefore, 10kV and above lines are mostly equipped with vibration dampers. However, in northern regions, strong winds and snowfall are common in winter and spring, and snow is more likely to accumulate at the vibration damper locations, increasing the load on the lines and fittings and making the lines more susceptible to damage or even tower collapse.

A fixing part for fixing cables is detachably installed on the side of the mounting plate. A sleeve is fixedly connected to the lower part of one side of the mounting plate. A steel strand is fixedly connected inside the sleeve. The two ends of the steel strand extend to the two ends of the sleeve. A hammer head is fixedly connected to the two ends of the steel strand. A de-icing and snow-removing device is provided on the mounting plate.

[0017] like Figure 1-3 As shown, an intelligent de-icing and snow-removing vibration hammer for power transmission lines includes a mounting plate 1. A fixing part 2 for securing cables is detachably mounted on the side of the mounting plate 1. A sleeve 3 is fixedly connected to the lower part of one side of the mounting plate 1. A steel strand 4 is fixedly connected inside the sleeve 3, with both ends of the steel strand 4 extending towards both ends of the sleeve 3. Hammer heads 5 are fixedly connected to both ends of the steel strand 4. A de-icing and snow-removing device is installed on the mounting plate 1. Specifically, the mounting plate 1 is placed on the side of the power transmission line, and then the power transmission line is secured using the fixing part 2. When the wind blows, the power transmission line vibrates, causing the hammer heads 5 to move up and down. The steel strand generates internal friction due to inertia, which, combined with air damping, dissipates the vibration energy.
[0018] The longitudinal section of the fixing part 2 is an arc-shaped structure, and extension plates 6 are integrally connected to both sides of the fixing part 2. Specifically, bolts are used to install bolts on the extension plates 6 to fix the fixing part 2 to the mounting plate 1.
[0019] The snow and ice removal device includes two connecting rods 7 vertically fixed to the top of the mounting plate 1. A solar photovoltaic panel 8 is fixedly connected to the top of the connecting rods 7, and a vibration motor 9 is fixedly connected to the side of the mounting plate 1. Specifically, the solar photovoltaic panel 8 converts solar energy into electrical energy, and the vibration motor 9 is activated when it snows to shake off the snow.
[0020] A snow sensor 10 is installed on the mounting plate 1; the snow sensor 10 can sense snowfall and thus start the vibration motor 9.
[0021] An energy storage battery 11 is installed on the side of the mounting plate 1 away from the vibration motor 9. The energy storage battery 11 is connected to an inverter 12 and is electrically connected to the photovoltaic solar panel 8. Specifically, the energy storage battery 11 stores electricity, and the inverter 12 converts the battery's current.
[0022] Hammer head 5 is rotatably connected to steel strand 4, and hammer head 13 is rotatably connected to the other end of hammer head 5. Specifically, if a bird stands on hammer head 5 or hammer head 13, it will start to rotate, and the bird will lose its footing.
[0023] The snow sensor 10 is connected to the controller 15, which is equipped with a wireless transmission module. Specifically, the snow sensor 10 transmits snow signals to the controller 15, which then feeds back the signals to the vibration motor 9. The vibration motor 9 then shakes the snow off.
[0024] The mounting plate 1 has an arc-shaped groove 16; specifically, the arc-shaped groove 16 facilitates the placement of cables.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
