The vane unit of the power device by utilizing wind energy is formed by a plurality of vanes in the premise of without increasing the weight so that the structure is called as a duplex type vane so as to increase the density of the vane or the lift force of the vane to further increase the utilization efficiency of the wind energy of a fan with a vertical shaft.
Description
Technical field
The invention belongs to a kind of blade of wind driven electric plant, particularly relate to the blade of vertical shaft Wind Power Utilization power plant.
Technical background
Because the area of blade in sweeping the wind face and the ratio of wind sweeping area of vertical-shaft fan, promptly the solidity of blade is little more a lot of than the solidity of horizontal fan blade, has influenced the efficient of vertical-shaft fan so greatly.But vertical-shaft fan has big cost advantage at aspects such as design, manufacturing, installation, transportations, causes the efficient that improves vertical-shaft fan to seem especially important.Though can reach the purpose that increases the blade solidity by the width that increases single blade, aerodynamics requires the thickness of lift-type blade also corresponding increase must be arranged, thereby causes the weight of blade to be multiplied.The drawback that this method is brought is the weight that has increased the load and the wind wheel of blower fan, therefore can not effectively improve the efficient of blower fan.
Summary of the invention
The purpose of this invention is to provide a kind of under the prerequisite of not gaining in weight, thereby increase the blade solidity or increase the blade that blade lift reaches a kind of Wind Power Utilization power plant of the Wind Power Utilization efficient that improves vertical-shaft fan.
Purpose of the present invention can be by realizing by the following technical solutions: a kind of blade of wind driven electric plant, it is made up of at least two blades, the belly of a blade in the adjacent blades is towards the back of another one blade, and the head of adjacent blades in the same way, one end of described blade is connected with upper beam by axle, the other end of blade is connected with bottom end rail by axle, and described at least two blades and upper and lower crossbeam connect to form a blade unit.Purpose of the present invention can also be by realizing by the following technical solutions: a kind of blade of wind driven electric plant, it is connected composition combined blade unit by the upper beam of an above-mentioned blade unit by an end is connected, passes through the other end with upper arm bottom end rail at least with underarm.
The blade unit of above-mentioned wind driven electric plant is under the prerequisite of not gaining in weight, with blade unit of several blade structures, this structure is referred to as duplex blade, thereby reaches the Wind Power Utilization efficient that improves vertical-shaft fan to increase the blade solidity or to increase blade lift.Blade unit all has new characteristics aspect structure and performance two: the one, and for identical solidity, the weight of above-mentioned blade unit is half of single leaf weight on the structure; In other words, for the weight that equates, the solidity of above-mentioned blade unit is twice than the solidity of single blade.The 2nd, have new characteristics on the performance, its meaning is bigger, and when the above-mentioned blade unit of distinguished and admirable process, first blade is with the distinguished and admirable quick stream at its back and the stream at a slow speed of belly of being divided into, and the pressure difference that produces forms lift like this.Liu density is greater than the density that flows fast at a slow speed, second blade places the rear of the first blade belly, and its distance and angle just in time make second blade that the first blade belly rear distinguished and admirable is further divided into the stream at a slow speed of the quick stream at the second blade back and belly and produce lift.Produce two results like this, one to be that the existence of second blade gets the rheology at a slow speed of the first blade belly slower, and the lift that first blade is produced increases; Two is second blades self with the further shunting of the highdensity stream at a slow speed of the first blade belly, and the lift of generation is also greater than the lift of common distinguished and admirable density (being to have produced interaction by distinguished and admirable between the blade).The lift that above-mentioned like this blade unit produces produces the lift sum separately greater than first blade and second blade, played one-plus-one greater than two effect.
Different arrangement mode between the first above-mentioned blade and second blade causes the performance of the blade unit that constitutes that different characteristics is arranged.If the head of second blade is facing to the afterbody of first blade, the requirement of distance between the two and angle aerodynamic, make high speed flow and the low-speed flow of shunting after through first blade when distinguished and admirable, continuation is further quickened respectively by the back of second blade and belly and is slowed down, and forms the relay effect before and after two blades and increases lift.
Therefore, above-mentioned blade unit has not only increased solidity, has increased lift, and has opened up new approach for reducing the blower fan cost.
