Abstract

A wind-force generating system includes a tower generating part, and the tower generating part comprises an S-typed starting wind-wheel, an operating wheel and a circular operating flywheel which are sequentially installed and fixed on a vertical wind-wheel spindle located in the middle of a power tower. A lower end of the vertical wind-wheel is fixedly connected with an input axis of a generator group. The generator group disposed on the ground is located inside a lower arch of the power tower. Frictional disks are respectively disposed at the opposite spot of two bilateral-ends of the operating wind-wheel, and the frictional disks are fixedly connected with the front end of a plunger of a hydraulic cylinder which is fixed on the power tower. Due to the S-type of the wind-wheel, the utility model can drive the wind-wheel to rotate by wind blew from whichever direction, thereby saving the costly position aerofoil. The utility model has the advantages of stable operation, high generating efficiency, convenient manipulation and maintenance and the like.

Description

Wind generating unit

(1) technical field

The utility model relates to a kind of electricity generating device, particularly relates to a kind of wind generating unit of the S of employing wind wheel.

(2) background technique

Along with the high speed development of industrial and agricultural production and the demand that improves day by day electric power of living standards of the people increase sharply, imbalance between supply and demand is very outstanding.The generation current mode is mainly based on thermal power generation and water generating.Concerning a country, can be limited for the water resource of generating, and thermal power generation is to be fuel with the coal, thermal power generation can cause certain pollution to environment, particularly coal is non-renewable energy resources, and is valuable industrial chemicals, and underground reserves are limited, and wind-force and solar energy, then be inexhaustible cheap clear energy sources, good market prospects are arranged, therefore should develop energetically, actively apply.

Present known tower-type wind generating device, its generator is fixed on the platform of head tower top, alternator shaft is connected with the blade wheel by bearing bracket, the blade wheel is equipped with blade up and down, blade links to each other with the directed wind wing, so that blade aligns wind direction, utilize the wind-drive blade to drive generator shaft and rotate and generate electricity.This device fan blade size can not be adjusted automatically with the wind-force size, also needs to determine wind direction by the directed wind wing stationarity of not only complicated operation, and influence generating and the raising of generating capacity.

(3) summary of the invention

The technical problems to be solved in the utility model provides a kind of big I of blade size adjusting automatically with the wind of electricity generating device, but automatic speed regulation, autostop, wind generating unit simple to operate, easy to maintenance, that generating is steady, generating capacity is strong.

The technical measures that adopt are:

Wind generating unit comprises control section and tower power generation part.

Tower power generation part comprises electric power tower, starting wind wheel, at least one operation wind wheel, vertical wind wheel shaft, operation flywheel and generator set.Starting wind wheel and operation wind wheel are S type wind wheel, starting wind wheel and operation wind wheel are fixed on the same vertical wind wheel shaft successively, fixedly connected with the input shaft of generator set in the lower end of vertical wind wheel shaft, the operation flywheel is fixed on the rotor shaft, is positioned at the below of operation wind wheel.Two side ends corresponding position at the operation flywheel is provided with hydraulic brake mechanism.Electric power tower lower end is fixed on the ground, and the generator set setting on the ground.

The electric power tower is provided with a plurality of platforms, is beneficial to assembling and maintenance, and platform is provided with a plurality of lighting burners.On electric power tower platform topmost, stand and be provided with the lightning conductor tower, on the lightning conductor tower, be fixed with a chain-wales, on chain-wales, be equiped with height beacon light (preventing that flying object from hitting by mistake) and wind speed and direction detector (commercial product).

Control section comprises an electric control cubicle (commercial product) and computer, hydraulic transmission control system, wind speed and direction detector.The control program that has establishment at built-in computer.Control section can be monitored the whole service process of tower power generation part, realizes that automatic startup-shutdown, speed governing, energy switching, emergency braking and wind speed show, wind direction shows, wind wheel dynamically shows, rotating speed shows, contact shows, fault shows, demonstrations such as the demonstration of service hours word and electric current, voltage, power, electric weight, frequency.

Advantage of the present utility model is to start wind wheel and the operation wind wheel is the S type, the wind of any direction all can blow this S type wind wheel running, thereby saved the directed wind wing, not only simple in structure, and easy to operate, particularly S type wind wheel can launch and shrinks with wind speed size, the stationarity that turns round with the maintenance wind wheel, thereby also make the generator operation balance, guaranteed the stability of electric power output.Owing to also be equiped with the operation flywheel; the inertia that the rotation of operation flywheel is produced, the running that not only helps S type wind wheel is steady, and can make the stop motion of operation flywheel by hydraulic braking when needed; thereby also having, realization autostop, the utility model make an inspection tour and advantage such as easy to maintenance.
