Abstract
The utility model discloses an umbrella type blade for floor type wind generator which comprises a floor type wind generator and a longitudinal generator shaft, wherein the generator shaft is horizontally provided with an upper and a lower layer of horizontal bar, four vertical bars with blades are arranged vertically between the two layers of horizontal bar, the blade is in umbrella structure and arranged along the vertical bar in sequence from up to down, a pull rod is connected among blades on each vertical bar and is controlled by a limit switch arranged on the horizontal bar. When the blade drives the generator shaft to rotate, the sensor emits a signal to control the limit switch according to the wind direction and wind direction location to make each set of blade to open and close at the right position through the pull rod, thus the blade is ensured to be closed in the rotation process while the blade is upright with the wind direction, and is 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 in opening and closing operation, the action is simple and easy with a strong practicability.
Description
Technical field
The utility model relates to wind-driven generator, especially relates to a kind of wind-driven generator umbrella formula blade that lands.
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 umbrella formula blade that lands of providing at above-mentioned 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 umbrella formula 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 blade-carrying vertical rods, it is characterized in that: described blade is beveled structure, along vertical rod order arrangement up and down, between the blade that is provided with in the every vertical rod, be connected with pull bar, described pull bar is by the position control switch control that is arranged on the cross bar place.
Install and maintenance for convenient, described position control switch is arranged on the lower cross bar.
Advantage of the present utility model is that blade is beveled structure, along vertical rod order arrangement up and down, is connected with pull bar between the blade that is provided with in the every vertical rod, and described pull bar is by the position control switch control that is arranged on the cross bar place.When the vane drive generator shaft rotates, 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 pull bar opens in place and closes, guarantee that blade opens when perpendicular with wind direction in rotary course, facing the wind, maximally utilise wind energy with each umbrella shape concave surface of blade, closure when other positions has reduced resistance again; Because position control switch control blade only carries out opening and closing two bit manipulations, moves simply, is 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 umbrella formula 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 vertical rods 6 that have blade 5, described blade 5 is beveled structure, along vertical rod 6 order arrangement up and down, be connected with pull bar 7 between the blade 5 that is provided with in the every vertical rod 6, described pull bar 7 is by position control switch 8 controls that are arranged on the lower cross bar 4.
Claims (2)
1, a kind of wind-driven generator umbrella formula blade that lands, it comprises floor model wind-driven generator (1) and the generator shaft (2) that vertically is provided with, going up the horizontal interval at described generator shaft (2) is provided with, following two-layer cross bar (3,4), at two-layer cross bar (3,4) be vertically installed with four vertical rods (6) that have blade (5) between, it is characterized in that: described blade (5) is beveled structure, along vertical rod (6) order arrangement up and down, be connected with pull bar (7) between the blade (5) that every vertical rod (6) upward is provided with, described pull bar (7) is by a position control switch (8) control that is arranged on the cross bar place.
2, blade according to claim 1 is characterized in that: described position control switch (8) is arranged on the lower cross bar (4).
