Abstract
The utility model discloses a shutter type blade for floor type wind generator , which comprises a floor type wind generator and a longitudinally located generator shaft, wherein the generator shaft is horizontally provided with an upper and lower layer of horizontal bar, four sets of blade are arranged vertically between the two layers of horizontal bar, the blades from the top to the bottom are assembled into a shutter structure, the blade is controlled by a limit switch on the horizontal bar through a pull wire. When the blade drives the generator shaft to rotate, the sensor emits an signal to control the limit switch according to the wind direction and wind direction location, the limit switch can control each blade set to open and close at right position through the pull wire, thus the blade is ensured to be closed in the rotation process while the blade is upright with the wind direction, and opened in the other position so as to reduce the resistance and maximally utilize the wind energy. Because the limit switch only makes each set of blade to operate by opening and closing, the actions are simple and easy to operate with a strong practicability.
Description
Technical field
The utility model relates to and lands wind-driven generator, especially relates to landing wind-driven generator louvered blade.
Background technique
At present the wind-driven generator that uses mostly is electric fan formula structure, and blade is the windmill shape, the windward side of blade and wind-force direction out of plumb and can not adjust in the work, and the wind power utilization rate is low, and the wind-powered electricity generation conversion efficiency is not high.A kind of utility model patent of standing wind-power generator machine was disclosed in 2005, its blade can be adjusted, and blade is when rotating with the wind-driven generator axle, under the sensor indication that determines the wind direction, with the drive motor rotation, adjust blade and make that its windward side is vertical with wind direction, the opposite side blade is parallel with wind direction.But experiment showed, that motor is a multidigit to the driving of blade, and certain hysteresis arranged that the opposite side blade is parallel with wind direction with wind direction is vertical in the windward side of very difficult assurance blade.
The model utility content
A kind of wind-driven generator louvered blade that lands of providing at the deficiencies in the prior art is provided the purpose of this utility model.
For achieving the above object, the utility model can be taked following technical proposals:
The wind-driven generator louvered blade that lands described in the utility model, it comprises floor model wind-driven generator and the generator shaft that vertically is provided with, the horizontal interval is provided with upper and lower two-layer cross bar on described generator shaft, between two-layer cross bar, be vertically installed with four groups of blades, it is characterized in that: the louvre type structure of described blade for being combined into one from top to bottom, described blade pass are crossed backguy by the position control switch control that is arranged on the cross bar.
For being easy to install and maintain, described position control switch is arranged on the lower cross bar.
Advantage of the present utility model is that blade is the louvre type structure that is combined into one from top to bottom, and described blade pass is crossed backguy by the position control switch control that is arranged on the cross bar.In vane drive generator shaft rotating process, sensor sends instruction according to wind direction and wind direction position, control bit control switch, making a control switch control every group of blade by backguy opens in place and closes, guarantee blade in rotary course with wind direction closure when perpendicular, when other positions, open, reduced resistance, maximally utilised wind energy; Because control switch in position is controlled every group of blade and only carried out opening and closing two bit manipulations, move simply, be easy to realize that practicability is extremely strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, the wind-driven generator louvered blade that lands described in the utility model, it comprises floor model wind-driven generator 1 and the generator shaft 2 that vertically is provided with, the horizontal interval is provided with upper and lower two-layer cross bar 3,4 on described generator shaft 2, between two-layer cross bar 3,4, be vertically installed with four groups of blades 5, the louvre type structure of described blade 5 for being combined into one from top to bottom, described blade 5 is controlled by the position control switch 7 that is arranged on the lower cross bar 4 by backguy 6.
Claims (2)
1, a kind of wind-driven generator louvered blade that lands, it comprises floor model wind-driven generator (1) and the generator shaft (2) that vertically is provided with, go up the horizontal interval at described generator shaft (2) and be provided with upper and lower two-layer cross bar (3,4), between two-layer cross bar (3,4), be vertically installed with four groups of blades (5), it is characterized in that: the louvre type structure of described blade (5) for being combined into one from top to bottom, described blade (5) is controlled by the position control switch (7) that is arranged on the cross bar by backguy (6).
2, blade according to claim 1 is characterized in that: described position control switch (7) is arranged on the lower cross bar (4).
