Vibration energy collecting circuit vibration-prevention hammer for providing energy for wireless sensor

Abstract

The invention discloses a vibration energy collecting circuit vibration-prevention hammer for providing energy for a wireless sensor, and relates to a circuit vibration-prevention hammer. The vibration energy collecting circuit vibration-prevention hammer aims at solving the problem that an existing vibration-prevention hammer purely consumes circuit vibration energy, and the vibration energy cannot be converted to be used for supplying power to a wind speed wireless sensor. A bushing sleeves a wire, a cable clamp assembly is installed on the bushing, a supporting plate is connected with the lower end of the cable clamp assembly through supporting plate screws, a left cantilever beam resonance device and a right cantilever beam resonance device are symmetrically fixed to the two sides of the supporting plate on the same horizontal plane, a power processing unit module is installed on the middle of the supporting plate, and a wireless wind speed sensor module is installed on the supporting plate below the power processing unit module. The vibration energy collecting circuit vibration-prevention hammer is used for overhead lines, and gentle breeze vibration energy is converted into electric energy through the special resonance devices on the vibration-prevention hammer to be supplied to the wind speed wireless sensor.

Description

technical field [0001] The invention relates to an anti-vibration hammer for overhead lines, in particular to a vibration-energy-collecting line anti-vibration hammer for supplying energy to wireless sensors. Background technique [0002] Breeze vibrations of transmission lines and wind vibrations of transmission towers often cause extremely harmful faults such as broken strands and wires of transmission lines, node connection damage of towers, etc., and have repeatedly caused large-scale power outages with serious impacts. There are three forms of wind-induced conductor vibration of overhead transmission lines: breeze vibration, sub-gap vibration and galloping, among which the breeze vibration of conductors occurs most frequently and has the greatest impact. The breeze vibration of the conductor is due to the periodic "Karman vortex" excitation generated behind the conductor when the wind blows vertically through the conductor, which produces a force on the conductor perpen...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that vibration energy is simply consumed by current anti-vibration hammers in the process of line anti-vibration. To solve this problem, a vibration energy collection line anti-vibration hammer for supplying energy to wireless sensors is provided to make the energy collection type anti-vibration The hammer is more practical and does not need to install other devices to ensure the structure is simple enough. The piezoelectric cantilever beam with energy conversion function is used instead of the traditional steel strand, which can not only ensure the structure of the shockproof hammer is simple enough, but also avoid the need for special installation. The problem of line flashover and device damage caused by the device also reduces the workload of maintenance personnel.
