Abstract
This invention is a spout for an air blast blade. The rotatable spout links to the top of the blade. To the spout installs a device to keep the air direction blow out.
Description
Invention field
The present invention relates to wind energy conversion system, especially a kind of wind machine oar leaf spout with puff prot.
Background technique
In order to improve existing wind energy conversion system efficient, the blade of some wind energy conversion system is provided with puff prot.Such as, " a kind of wind machine oar leaf " that the inventor once proposed with puff prot.Modern wind machine, especially large scale wind power machine adopt the blade of variablepiston mostly, because puff prot is fixed on the blade, the change of pitch can influence the jet direction of puff prot on the blade, and when puff prot departed from the blade plane of rotation, the thrust of jet generation obviously reduced.
Summary of the invention
At the deficiencies in the prior art, the objective of the invention is to propose a kind of spout that is used for jet blade, it can keep the jet direction of puff prot automatically when the wind machine oar leaf pitch changes.
The object of the present invention is achieved like this: a kind of spout that is used for jet blade, and blade is provided with puff prot, and puff prot connection source of the gas is also and the blade formation is rotatable connects, and puff prot is provided with the mechanism that can keep jet direction.
The present invention also has following further step on the basis of such scheme:
Described puff prot connects source of the gas by selector valve.
Described puff prot is provided with airvane or steering equipment.
Described puff prot constitutes rotatable the connection by quill shaft and blade.
The described mechanism of jet direction and the control mechanism of keeping constitutes controlled architecture.
Advantage of the present invention is as follows:
Because puff prot is provided with the mechanism that can keep jet direction.So when the pitch of blade changed, puff prot still can keep best jet angle.The present invention is simple in structure and practical, is particularly useful for the feather blade with puff prot.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing in detail embodiments of the invention are described in detail:
Referring to accompanying drawing.Blade (1) is provided with puff prot (5), puff prot (5) by pipeline (8) connect source of the gas and and blade (1) constitute rotatable connection, puff prot (5) is provided with the mechanism that can keep jet direction.Described puff prot (5) is a directional nozzle; Described source of the gas can send from the wind energy conversion system wheel hub.Puff prot (5) is fastened on the interior pipeline (8) of blade (1) by quill shaft (6).Can keep the mechanism of jet direction to be made of airvane (4) or steering equipment (7), airvane (4) can be installed in above or below the puff prot (5).Steering equipment is provided with drive motor and retarder in (7), and retarder connects quill shaft (6).Drive motor in the steering equipment (7) is controlled by direction control mechanism, direction control mechanism can be a sensor, the exportable electrical signal of sensor, be connected with drive motor again behind the electrical signal input amplifying circuit, the electrical signal of the exportable maintenance direction of sensor, it is similar with airvane (4) that the electrical signal of maintenance direction provides principle, but the steering equipment of present embodiment (7) is connected with a rotating speed control mechanism.The rotating speed control mechanism contains tachogenerator, tachogenerator connects selector valve (3) or steering equipment (7), when tachogenerator was measured the wind energy conversion system rotating speed and is higher than setting value, rotating speed control mechanism may command puff prot (5) was around quill shaft (6) rotation or drive selector valve (3) and open; Selector valve (3) is a solenoid valve, when selector valve (3) is opened, the gas of puff prot (5) is sprayed from reverse puff prot (2); Steering equipment (7) can make puff prot (5) 360 degree rotations, when tachogenerator is measured the wind energy conversion system rotating speed and is higher than setting value, the angle of swing of rotating speed control mechanism may command puff prot (5) can reach the purpose of controlling the wind energy conversion system rotating speed by the angle of swing of controlling puff prot (5).For the unstable state that prevents from may occur in puff prot (5) rotary course, establish damper at an end that connects quill shaft (6), damper can be simple brake structure.
A gradually opening apparatus can be set in the selector valve (3), so that the jet amount of selector valve (3) may command puff prot (5) when opening.
Be noted that, it is described that to keep the mechanism of jet direction also can be puff prot (5) itself, when quill shaft (6) is arranged on puff prot (5) one sides when (as shown in drawings), during blade (1) motion, puff prot (5) is subjected to asymmetric resistance of air can make puff prot (5) maintenance best jet position backward.
Described puff prot (5) is provided with baffler.One end of puff prot (5) is provided with rack saw shape spout or quincunx spout (being similar to fighter turbogenerator spout).
The outside of puff prot (5) can be provided with the cowling that reduces resistance of air, and the profile of cowling can be similar in appearance to the shape of blade blade tip.At this moment, described airvane (4) can be a cowling itself.
The described mechanism of jet direction and the control mechanism of keeping constitutes controlled architecture.Can keep the mechanism of jet direction to constitute controlled architecture, when control mechanism is connected with computer system, can control and adjust the rotating speed of wind energy conversion system easily by velocity measurement mechanisms and control mechanism.
Claims (6)
1, a kind of spout that is used for jet blade is characterized in that, blade is provided with puff prot (5), and puff prot (5) connection source of the gas also and the blade formation is rotatable connects, and puff prot (5) is provided with the mechanism that can keep jet direction.
2, a kind of spout that is used for jet blade according to claim 1 is characterized in that, described puff prot (5) connects source of the gas by selector valve.
3, a kind of spout that is used for jet blade according to claim 1 is characterized in that, described puff prot (5) is provided with airvane or steering equipment.
