Embodiment 2

[0051] This embodiment discloses a working method of a drag-type vertical axis wind turbine: when the unidirectional wind acts on the fan blades arranged in pairs, one of the fan blades in the fan blades arranged in pairs will When the rotating shaft rotates, a gap for wind flow is formed between adjacent wind choke plates, and the wind choke plate of the other fan blade is attached to the mesh limit structure under the action of wind force. At this time, the wind force acting on the two blades forms a pressure difference , Under the action of the pressure difference, the fan blades drive the rotor to rotate, and the rotation of the rotor drives the generator to generate electricity.

[0052] Using this power generation method, compared with the traditional drag-type wind generator, it can form a higher rotational moment, and the power generation efficiency is high.

Embodiment 3

[0054] This embodiment discloses a working method of a resistance type vertical axis wind turbine: the speed sensor collects the speed information of the drum in real time and transmits it to the controller. When the wind speed changes, the controller receives the wind speed change signal transmitted by the speed sensor , to control the operation of the first motor, the drive belt drives the fan blades to move along the cantilever frame mechanism, changing the distance between the fan blades and the rotation, so that the rotation speed of the drum returns to the set value again, so that the generator outputs electric energy according to the set power.

Embodiment 4

[0056] This embodiment discloses a braking method for a resistance-type vertical axis wind turbine: the second motor operates, the connecting belt is released, and the wind choke plate slides down along the T-shaped slot under the action of gravity and is stacked on the receiving rod. At this time, the fan The stressed area of ​​the leaf is greatly reduced, the rotating speed is gradually reduced, and braking is realized.

Abstract

The invention relates to a resistance-type perpendicular shaft wind turbine and a working method thereof. The wind turbine comprise a rotary drum connected with a generator, wherein the rotary drum can drive the generator to generate electricity through self-rotation; the rotary drum is connected with a plurality of pairs of fan blades through a cantilever frame structure; two fan blades in each pair of the fan blades are arranged at a 180-degree angle; the fan blades are connected with a distance changing mechanism; the distance changing mechanism can adjust the distance between the fan blades and the rotary drum; the fan blades comprise a plurality of wind blocking plates rotatably connected with a frame; and a netted limiting structure is arranged on one side of each wind blocking plateand fixedly connected with the frame. According to the wind turbine, the generating efficiency is high and constant power output of electric energy is achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a resistance type vertical axis wind turbine and a working method. Background technique [0002] At present, the commonly used vertical axis wind turbines are lift type and resistance type wind turbines. The existing resistance type wind turbines generate torque because the two sides of the blades have different drag coefficients, and the ratio is about 1 / 2 at rest. , the inventor finds that the area of ​​the blades at the windward and windward positions is the same. This makes the speed and torque produced by the existing resistance type wind turbine very small, and the efficiency is very low. [0003] The inventor also found that the current resistance generator cannot maintain a constant output power according to the wind force, the output electric energy is unstable, and the safety of the equipment cannot be guaranteed.
