The vibration-initiating ball is arranged at one side of the metal harmonic oscillator; and the permanent magnet is arranged in a gap of the iron core. The power-generating device is advantageous in simple structure, small dimension and low cost; with the power-generating device adopted, and idle energy can be effectively utilized; and the power-generating device is suitable for advantageously being adopted as a working power supply of a small-power intelligent sensing device of the overhead power transmission lines.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), relates in particular to the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of utilizing the lead wire and earth wire in transmission line aeolian vibration.
Background technology
Overhead transmission line galloping, aeolian vibration are the most general forms of ultra-high-tension power transmission line vibration, also are simultaneously the main causes of destroying the power transmission line damage.The overhead wire aeolian vibration is the vibratory overhead line phenomenon that a kind of vortex (toll bar vortex) of gas alternately comes off and produces at the overhead wire leeward side, it is characterized in that frequency high (3 ~ 120Hz), amplitude generally can not surpass diameter of wire, vibration frequency and wind speed, diameter of wire are relevant, determine that by formula: F=200V/d wherein V is the wind speed perpendicular to overhead wire, unit: meter per second, d is the overhead wire diameter of wire, unit; Rice.Nearly all high voltage circuit all is subject to the impact of aeolian vibration at present, especially on transmission lines large crossing, because of the characteristics such as have that span is large, hitch point is high and the waters is open, the vibrational energy that makes wind impose on lead wire and earth wire increases greatly, and the lead wire and earth wire oscillation intensity is serious far beyond common span.Also find no at present the device that utilizes the lead wire and earth wire in transmission line aeolian vibration to generate electricity.
Summary of the invention
The purpose of this utility model provides a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) of utilizing the lead wire and earth wire in transmission line aeolian vibration, and this apparatus structure is simple, small volume, and cost is low, has effectively utilized the idle energy.
The technical solution of the utility model is: a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) of utilizing the lead wire and earth wire in transmission line aeolian vibration, it is characterized in that: this vibration generating device is by forming with the starting of oscillation ball of spring or spring leaf and permanent magnet and the iron core of metal harmonic oscillator and metal harmonic oscillator front end, the starting of oscillation ball places tuning fork one side, and permanent magnet places between the iron core breach.
This apparatus structure is simple, and small volume, monomer are output as the power of mW level, if adopt integrating effect, its multicomponent is criticized being installed on the ground wire or on the wire, in addition can with circuit on bird-resistant combine use, can reach the power of 5W to 10W; Its profile can be with reference to shape and the performance design of stockbridge damper.This device is fit to as the smaller intelligent sensing device power supply (DPS) of overhead transmission line power, and has superiority.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, this equipment is that a kind of kinetic transformation that lead wire and earth wire on the transmission line can be vibrated be the vibration generating device of electric energy.
When vibration generating device is vibrated with the lead wire and earth wire motion, knocking metal harmonic oscillator 2 with the starting of oscillation ball 3 of spring or spring leaf 1 is tuning fork, makes permanent magnet 6 in the 7 intercropping simple harmonic vibrations of iron core 4 breach, relatively cutting magnetic line, namely produce electromotive force in the coil 5, form electric current.Its metal harmonic oscillator 2 is made for copper alloy, has preferably resonance performance.
Installation instructions
With fixing upper folder, fixing lower folder, U-shaped fixedly shroud ring (two) and hold-down nut Blast Furnace Top Gas Recovery Turbine Unit (TRT) is installed on the transmission line.
