Description
Technical field
The present invention relates to a kind of wind generating unit that utilizes natural energy resources.More specifically, the protective gear that relates to the windmill when running into high wind.
Background technique
In the past, the protective gear of relevant this windmill when running into high wind etc., the blast that known with good grounds windmill bears changes the variable spacing formula wind generating unit of the spacing of rotor blade.And, the blast that also with good grounds windmill bears and shake variation from the side displacement mode wind generating unit of the suspended pattern constant spacing mode of the windmill of pivot suspention, generator etc.One in this mode is, utilizes direction plate and the output that is installed on this direction plate to adjust spring, so that no matter how wind speed makes it only apply roughly certain wind-force mode to windmill, according to blast displacement windmill rotating speed.And when running into storm wind, the direction of apparent wind is met wind towards down the wind being indexed to the side, is located at the position of resistance minimum, and thus windmill is protected.Be disclosed in as above-mentioned mode, for example the spy opens clear 58-128471 communique.On the other hand, before the propeller cavitation of screw shaft, be provided with in the brake disc mode of brake disc, brake by the crimping of brake disc being produced friction when the high wind.Above-mentioned mode for example is disclosed in, and the spy opens in the clear 56-77573 communique.
In above-mentioned wind generating unit in the past, the wind speed of natural wind is strong, for example under the situation of the wind speed 60m/s during entablement wind, since high wind, the windmill high speed rotating.Thus, the intensity of the blade of windmill is carried out mechanical vibration and pulsation repeatedly under situation at a high speed, and produces the material deterioration or the be full of cracks of blade.And it is final if surpass the problem that the breakdown point of the internal stress of material has the breakage that brings blade.One implement a lot of countermeasures for this reason always, when high wind, change the variable spacing formula of the speed of rotor blade as can be known.But this mode needs numerous attendant equipments such as rotation transfer mechanism.And though also have hanging type constant spacing mode, this mode also has rotation transfer mechanism, spring mechanism, needs numerous attendant equipments.And, in the brake disc mode, needing spring mechanism, this mode is owing to carry out stop by frictional force, and the new problem of the breakage etc. of friction part is arranged.And, also have and start electromagnetic brake and make its braking so that the mode of rotor blade not.
In above-mentioned mode in the past, there are complex structure, installation cost price height and need the problem of many operations such as the needs of periodic maintenance etc. owing to have complicated structure in order to ensure function thus.And, starting under the situation that electromagnetic brake brakes,, the certainty problem that waits of stopping that can not continuing windmill is arranged if when there is fault in storage battery.
Summary of the invention
So the present invention has solved above-mentioned problem in the past, purpose provides a kind of simple, reliable and low price, and the protective gear of the windmill of repair cycle cycle length.
Wind generating unit of the present invention, possesses the natural wind of seizure and windmill that rotates and the storage battery that its rotational energy is transformed into electric energy and stores, wherein, possess the centrifugal impeller that the rotating shaft coaxle with windmill is provided with, centrifugal impeller forms the fan with the cover that prevents to catch natural wind.

(embodiment 1)
The integral body formation of the wind generating unit of present embodiment possesses: windmill 1; Prevent the fan 20 of the too fast rotation of windmill 1; The rotational energy of windmill is transformed into the electricity generating device 30 of electric energy; Storage is by the electric accumulator 40 of the electric power of electricity generating device generation; With the lighting set 50 that uses electric power storage to turn on light at the electric power of electric accumulator.And windmill 1, fan 20, electricity generating device 30, electric accumulator 40 and lighting set 50 are according to putting into 2 modes between the post 2 from remaining on specified altitude separately on the ground.And post 2 is arranged on the ground by mounting platform 3.Fixed block by anchoring bolt etc. is provided with this mounting platform 3.
In the bottom of electricity generating device 30 lighting set 50 is installed, is equipped with illumination unit 15 in inside.
In the inside of electric accumulator 40, be provided with Direct box 16 and lead storage battery 17, by illuminance transducer can light a lamp automatically, lamp disappears.And electric accumulator 40 has been equipped with the inspection door 18 in order to keep in repair.
Fig. 4 represents, in the present embodiment, and during monomer operation windmill 1, during monomer operation fan 20 and the characteristic separately when a running body windmill 1 and fan 20.In Fig. 4, the property list of the rotating speed of expression nature wind speed and windmill and fan.Curve 101 is roadabilitys of windmill 1 monomer, and is roughly proportional and increase the rotating speed of windmill 1 with the increase of natural wind speed.And curve 102 is part throttle characteristics of fan 20 monomers, the rotating speed of the increase fan 20 of corresponding natural wind speed and 2 powers of natural wind speed are proportional and increase.At this, the curve 103 of the kinetic characteristic when fan 20 is installed in windmill 1 is the roadability that deducts curve 102 from curve 101, the running state that expression is actual.And, the situation of the wind speed 60m/s about as the situation of the common wind speed 15m/s of the CLV ceiling limit value of wind speed and typhoon the time, below to the too fast rotation of windmill 1 prevent be illustrated.
In addition, the CLV ceiling limit value of common wind speed is made as 15m/s, the rated wind speed of wind generating unit is set in 15m/s, this is the generation power when not storing the wind speed that surpasses above-mentioned setting in electric accumulator 40, thereby CLV ceiling limit value is made as 15m/s.At this, shown in curve 103, the monomer of windmill 1 operation in limited time is about 1000r/min on the common wind speed of 15m/s, is about 800r/min when fan 20 is installed.Can draw thus, the rotating speed inhibiting rate that is reduced that the rotating speed of the windmill 1 behind the fan 20 is set is 20%.Relative therewith, the operation of the monomer of windmill 1 is about 4400r/min during wind speed 60m/s when typhoon, is about 2150r/min when fan 20 is installed.So, increase thereby the rotating speed inhibiting rate becomes 51% rotating speed inhibiting rate.Though this is owing to the characteristic of windmill 1 and wind speed is proportional and increase rotating speed, the characteristic of fan 20 is to increase rotating speed with 2 powers with respect to the increase of wind speed.As a result of, when coaxial connection windmill 1 and fan 20, reduce inhibition, suppress the rotation of windmill 1 in high wind speed range the rotation of windmill 1 in the low wind speed range of fan 20.Thus, thus natural wind speed suppresses the rotating speed of windmill 1 greatly when becoming high wind prevent too fast rotation.
Below, other the embodiment to wind generating unit of the present invention is illustrated according to plan.In addition, when the formation that has with the same function of the foregoing description, the mark prosign also omits explanation.And about in following embodiment, there not being illustrated other formation to have the formation same with the foregoing description.
In addition, electric accumulator 40 also can utilize capacitor except that lead storage battery.
