Embodiment 1

[0047] This embodiment will introduce the structure of the fan blade 101 and its installation method in detail.

[0048] Such as Figure 1~5 The fan blade 101 is shown, and the fan blade 101 is provided with an empennage structure. The empennage structure is a kind of oblique empennage structure, and the empennage utilizes the aerodynamic principle to improve and generate a certain force. Through the blades 101, the wind force received by the empennage is in the same direction in different wind directions. The empennage converts the wind force into the rotational force of the blade 101, and finally presses the blade 101 on the stop device 104, thereby ensuring the constant steering of the wind turbine. The structure of the empennage ensures that the steering of the wind turbine does not change. exist Figure 3-5 Among them, under the action of the wind direction 106, the wind blade 101 turns to 107 of the wind wheel bracket 102 as shown in the figure. direction, the fan bla...

Embodiment 2

[0054] The present invention will introduce the wind measuring system and the stopping device 104 in detail. The stopping device 104 is fixed to the wind wheel bracket 102 and can stop the rotation of the wind blade 101 . The stopping device 104 can be a protruding end arranged on the wind wheel support 102 , and the protruding end is fixedly connected with the wind wheel support 102 . The stop device 104 can also be fixedly connected to the wind wheel bracket 102, but can move in the vertical direction. The stop end can be adjusted manually. When the stop end protrudes from the wind wheel bracket 102 , can abut against the blade 101 to block the rotation of the blade 101, when the stop end shrinks into the wind wheel bracket 102, it will not hinder the rotation of the blade 101, and is suitable for use when the wind is strong and the wind speed is super safe. The stopping device 104 can also be a motor with an output end, such as a stepper motor, the output end is used as a s...

Embodiment 3

[0058] This embodiment will introduce in detail the implementation of the automatic control of the wind measuring device 105 and the stopping device 104 .

[0059] In this embodiment, the vertical wind turbine 100 can automatically adjust according to the wind speed.

[0060] Specifically, a wind measuring device 105 is connected to the stop device 104 with a motor.

[0061] Such as Figure 6 , Figure 7 , Figure 8 As shown, specifically, there is a wind measuring device 105 in the prior art, such as Figure 7 As shown, it is a spherical wind measuring system. It consists of two parts: a wind measuring ball and a whisker limit switch. The whisker limit switch can move in all directions, and the wind in any direction can trigger the whisker limit switch. Switch, when the wind measuring ball installed on the rocker of the cat whisker limit switch is under the action of wind greater than the safe operating wind speed, it will trigger the action of the cat whisker limit switc...

Abstract

The invention discloses a vertical wind turbine and a wind power generator, which are used to solve the problems of low wind power utilization rate and difficult starting of the existing wind turbines. The vertical wind turbine includes blades, a wind rotor bracket fixed to the rotating shaft, and a stop device arranged on the wind rotor bracket. Not equal, the stop device is provided with a stop end, and the stop end is used to abut against the fan blade to block the rotation of the fan blade. When the vertical wind turbine is started, the wind power is relatively small, thereby improving the utilization rate of wind power.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a vertical wind turbine and a wind power generator. Background technique [0002] Wind is a new energy source with great potential, and wind power generation is becoming a craze in the world, because wind power generation does not need to use fuel, nor will it produce radiation or air pollution. my country is extremely rich in wind resources, and the average wind speed in most areas is above 3 meters per second, especially in the northeast, northwest, southwest plateaus and coastal islands, where the average wind speed is even higher; All the time is windy. In these areas, the development of wind power generation is very promising. [0003] Wind power generation is to convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy. The principle is to use the wind force to drive the wind wheel to ro...
