Abstract

A kind of swing flat turn open-and-close type wind wheel is the utility model is related to, including firm banking, rotor shaft, air door frame, air door and door shield, rotor shaft are vertically arranged, and are rotatablely connected in the bottom insertion firm banking of rotor shaft and with firm banking；The rounded side for being equidistantly fixed on rotor shaft of multiple air door framves；Multiple air doors are rotatably connected on each air door frame；The door shield for making air door be stopped the rotation when rotating to precalculated position is installed on air door frame.Because there is provided door shield, when air door rotates under wind action power, the windward side of itself can be adjusted, make the air door of a part there is maximum windward side to drive the rotation of rotor shaft, and the air door of another part is then the resistance that minimum windward side reduces wind, ensure that the wind in either that direction to that air door can be enable to drive rotor shaft to rotate on air door, improves the efficiency of generating.

Description

A kind of swing flat turn open-and-close type wind wheel

Technical field

It the utility model is related to a kind of swing flat turn open-and-close type wind wheel.

Background technology

At present, the blower fan of wind-power electricity generation is all paddle formula wind turbine, has multiple blades around axisymmetry arrangement, Wind turbine power generation is driven by the rotation of blade, this generation mode blade rotating speed is slow, and the utilization rate of wind is low, direct shadow Generating efficiency is rung, and is limited by structure, the single-machine capacity of wind-driven generator can not be too big, and only large-scale wind wheel can just obtain greatly Type power, increases single-machine capacity, is rapidly developed China's wind-power electricity generation.

It is as illustrated in figs. 1 and 2, first Chinese patent：Swing flat turn open-and-close type wind wheel, application number 200720016189.9 are open A kind of swing flat turn open-and-close type wind wheel, it includes base, rotor shaft, has bearing on rotor shaft, wind wing frame 02 is connected with bearing, Rotor shaft is perpendicular to the ground, and wind wing frame 02 is arranged in rotor shaft surrounding in cross-shaped symmetrical, there is multiple wind wing doors on wind wing frame 02 01, each wind wing door 01 can rotate on door-hinge, and wind wing doorframe 03 is in the same side of wind wheel direction of rotation with respect to wind wing door 01.But When wind aweather wing door 01, wind wing door 01 automatically can rotate around door-hinge, with the posture presentation that resistance is minimum, into Fig. 1 or The position (wind wing door 01 with wind direction in same plane) of Fig. 2 apoplexy wings door 01, it is difficult to drive rotor shaft in wind to wind wing door 01 Rotation or the rotation of rotor shaft can not be driven at all, therefore generating efficiency is very low or does not have the effect of generating at all.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of swing flat turn open-and-close type wind wheel for finding efficiency high.

The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of swing flat turn open-and-close type wind wheel, including fixation Base, rotor shaft, air door frame, air door and door shield, the rotor shaft are vertically arranged, and the fixation is inserted in the bottom of the rotor shaft It is rotatablely connected in base and with the firm banking；Multiple rounded sides for being equidistantly fixed on the rotor shaft of the air door frame Face；Multiple air doors are rotatably connected on each air door frame；Being provided with the air door frame rotates to the air door The door shield to be stopped the rotation during precalculated position.

The beneficial effects of the utility model are：, can be with when air door rotates under wind action power due to there is provided door shield The windward side of itself is adjusted, makes the air door of a part have the windward side of maximum to drive the rotation of rotor shaft, and another part Air door is then the resistance that minimum windward side reduces wind, ensures that the wind in either that direction can make air door to air door Rotor shaft can be driven to rotate, improve the efficiency of generating.

On the basis of above-mentioned technical proposal, the utility model can also do following improvement.

Further, in addition to wind wheel bearing, mounting hole is provided with the firm banking, the wind wheel bearing is arranged on institute State in mounting hole, the bottom of the rotor shaft is inserted the wind wheel bearing and is rotatablely connected with the firm banking.

Further, in addition to the more axle of the air door being vertically arranged, the air door pass through the axle of the air door and the air door frame Rotation connection.
