Abstract
The present invention relates to a windmill device with the function of the wind power transduction in an aerogenerator. The device essentially comprises a veliform blade, a resistance blade, a control mechanism, an upper beam, a lower beam, and a centre shaft with the function of support and drive. According to the requirement of starting, high-speed rotation, and brake, etc., the aim of improving the starting performance, the power performance, and the rotor power coefficient is realized by the rational control of the radial position of the resistance blade.
Description
The present invention relates to rise in the vertical axis aerogenerator wind energy conversion system of wind energy transformation,, improved starting performance, power coefficient and the power performance of vertical axis windmill, reduced super, mistake phenomenon by changing the turning radius of resistance type blade.
Background technique
Existing vertical axis windmill mainly contains 2 types, and a kind is shaft resistance type windmill (its blade is called the resistance type blade), and a kind is Dari eritrea type wind energy conversion system (its blade abbreviates sail shape blade as) in addition.Shaft resistance type windmill self-starting torque is bigger, but high speed property coefficient and power coefficient are lower; Dari eritrea type wind energy conversion system high speed property coefficient and power coefficient are higher, but can not self-starting, and 2 types of wind energy conversion system characteristics and defective are all clearly.
Summary of the invention
In order to overcome the shortcoming of traditional vertical axis windmill, the present invention is by increasing the resistance type blade on the Dari eritrea type wind energy conversion system, and this resistance type blade can radially move, and moves to different positions as required, plays effects such as starting, traction at a high speed, braking.
Accompanying drawing 1 is master of the present invention, overlook principle schematic.
Its core texture of wind energy conversion system under the present invention mainly by sail shape blade, resistance-type blade and controlling organization, The compositions such as axis of lower and upper cross-member and a support, gearing. At wind-force effect apparatus for lower wind machine around middle shaft rotation Wind energy is converted into mechanical energy, and wherein the resistance-type blade can radially move on the crossbeam of wind energy conversion system, not The effects such as starting, at a high speed traction, braking are played in position together, to improve starting performance, the power of wind energy conversion system Performance and power coefficient, this is core of the present invention.
Purpose of the present invention is achieved through the following technical solutions: the number of sail shape blade and resistance-type blade is general All be 2 (also being applicable to more mutliblade wind energy conversion system), sail shape blade is fixed on the crossbeam outer end, the resistance-type leaf Sheet utilizes the modes such as pulley to move radially at crossbeam, and by controlling organization it is parked in as required to close Suitable position, whole wind energy conversion system rotates around the axis axis, wind energy is converted into mechanical energy and drives generator send out Electricity. At the beginning of wind energy conversion system begins to rotate and drives the generator generating, because sail shape blade can not self-starting, more Can not drive whole wind energy conversion system and rotate, this moment, the resistance-type blade played the power source effect, under the wind-force effect it Can drive whole wind energy conversion system and rotate around axis, for increasing the arm of force and starting torque, this moment, the resistance-type blade was general From axis away from (near sail shape blade), the start position shown in front view among Fig. 1. Because resistance-type leaf The high speed property coefficient (tip-speed ratio) of sheet is littler, and the radius of turn (being the arm of force) of blade is bigger in the starting, This moment, the wind energy conversion system rotating speed was smaller, and wind energy conversion system can't normal power generation. Under identical wind speed, to make resistance The type blade can continue the performance draw in higher rotation speed, must reduce its radius of turn. Reaching simultaneously After certain starting speed, sail shape blade has had certain tractive force, because the high speed system of sail shape blade Number is greater than 1, and it has the trend that drives the past higher rotational speed of whole wind energy conversion system, and resistance-type blade high speed system Number is less than 1, if do not reduce the radius of turn of resistance-type blade, the resistance-type blade not only can not drive wind energy conversion system High speed rotating more, and may hinder the traction of sail shape blade.
Therefore, starting back resistance type blade should move to axis under the effect of its control mechanism, its blade fraction surpasses axis, and the high speed distracted position shown in plan view among Fig. 1 forms the rotary flow type vertical axis windmill than the higher power coefficient of general shaft resistance type windmill tool.
Need shut down at wind energy conversion system, when slowing down, the resistance type blade can continue to move, when the center of blade surpasses middle axis, the effect that the resistance type blade will play braking, slow down, and the many more braking moments of overage are just big more.As a same reason, when wind speed changes, can make resistance type blade place by suitable control in place, realize that wind energy conversion system is crossed, stall control.
Thus, the present invention can improve the starting performance and the power coefficient of vertical axis windmill by reasonably controlling the relative position of resistance type blade, improves the power performance of wind energy conversion system.
