Description

Vertical shaft loose blade wind turbine

technical field

The utility model relates to a wind turbine, in particular to a vertical shaft movable blade wind turbine. the

Background technique

At present, the impellers of wind power generators used are generally composed of three wind blades running at 90 degrees in the crosswind, and the wind receiving area is small, and they must be placed on high towers. Long tail fins are used to control the windward direction of the wind rotor, and it is necessary to have abundant wind resources and conditions such as height difference and windward terrain to generate electricity. However, there are very limited areas with strong wind power and wind sources in windward terrain, which greatly affects the application and development of this environmentally friendly and cheap power generation energy. In addition, the difference between the inner and outer diameters of the blades of the flat-axis blade type side-turning wind turbine blades is too large. If the difference between the inner and outer diameters is too large, each blade cannot be synchronized with the wind and at the same speed. The blades are easy to break when encountering strong winds, and the blades are made quite thick. ,bulky. the

Today's vertical axis wind turbines are not perfect, and most of them have large blade rotation resistance, and the semi-wind-shielding type also has defects such as large main rod wind resistance and blade rotation disturbance. the

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a vertical shaft movable blade wind turbine with simple structure, reliability, material saving, uniform force, stable operation, durability, large wind area, and breeze start. the

A vertical shaft movable blade wind turbine, comprising a power generation transmission frame, a wind wheel support shaft is installed on the power generation transmission frame, a wind wheel fixed shaft is arranged inside the wind wheel support shaft, and the wind wheel fixed shaft passes through The directional running bearing is equipped with a rotating cylinder connected to the power generation system in the power generation transmission base. The rotating cylinder includes an upwind disk, a downwind disk and connecting pipes for the upper and lower disks. The connecting pipes for the upper and lower disks are installed on the On the above-mentioned directional running bearing, the upwind roulette and the leeward roulette are respectively fixed on the two ends of the connecting pipes of the upper and lower roulettes, and a plurality of can be evenly installed on the outer circumference between the upwind roulette and the leeward roulette Rotating blade rotating shaft, the blade rotating shaft is equipped with movable blade blades, and the outer circumference of the windward disk and the downwind disk is provided on the leeward side of each movable blade blade to prevent each blade from The opening angle of the fan vane exceeds the fan vane limit block of the preset angle. the

Using the above scheme, the device is equipped with several pairs of movable blades. When the blades rotate in the downwind, the blade surface faces the wind direction to receive the wind force and rotates with the wind to do work; when the blades rotate against the wind, , the blade surface of the movable blade wind vane rotates to be parallel to the wind direction, so that the rotation resistance is minimum. To sum up, the device is simple in structure, reliable, material-saving, uniform in force, stable in operation, durable in use, large in wind area, easy to start, and suitable for both large and small powers.

Detailed ways

Below in conjunction with accompanying drawing, describe the specific embodiment of the utility model in detail. the

As shown in Figure 1, it includes a power generation transmission frame 1, a wind wheel support shaft 2 is installed on the power generation transmission frame 1, a wind wheel fixed shaft 10 is arranged inside the wind wheel support shaft 2, and the wind wheel fixed shaft On the shaft 10, a rotating cylinder connected to the power generation system in the power generation transmission base 1 is installed through a directional running bearing 9. The rotating cylinder includes an upwind disc 8, a downwind disc 4, and an upper and lower disc connecting pipe 5. The upper and lower disc connecting pipes 5 are installed on the directional running bearing 9, the upwind disc 8 and the downwind disc 4 are respectively fixed at both ends of the upper and lower disc connecting pipe 5, the upwind disc 8 and the A plurality of rotatable fan blade rotating shafts 6 are evenly installed on the outer circumference between the downwind wheel discs 4, and movable blade wind blades 7 are installed on the fan blade rotating shafts 6, and the upper wind wheel discs 8 and the lower wind wheel discs 4 On the leeward side of each flap 7 on the outer circumference, there is a flap limiter 3 that prevents the opening angle of each flap 7 from exceeding a preset angle. the

When rotating in the downwind: the movable blade blade 7 is blocked by the blade limit block 3, so that the blade surface of the movable blade blade 7 faces the wind direction and accepts the wind push to do work; and when rotating against the wind: the wind force makes the movable blade blade 7 rotates around the fan blade rotating shaft 6, and the blade surface of the movable blade fan 7 is parallel to the wind direction under the effect of wind force, so that the work done by the headwind on the blade is reduced. the
