Problems solved by technology

However, when the wind speed is low, the blades of the vertical axis wind turbine are not enough to generate a large enough torque, that is, the wind wheel of the vertical axis wind turbine cannot drive the generator rotor to rotate at a low wind speed, which directly affects the Start-up of vertical axis wind turbines

Embodiment 1

[0023] As shown in Fig. 1 and Fig. 2, it is the lateral and longitudinal cross-sectional schematic view of the clutch of Embodiment 1 of the present invention. The clutch includes five extension springs 3 arranged radially along the vertical shaft, one end of the extension springs 3 is connected to the contact block 4, the outer ring 5 connected to the generator rotor, and the inner ring 6 connected to the vertical shaft sleeve 2 are installed on The blades on the supporting wing drive the inner ring 6 to rotate with the wind wheel through the connection between the supporting wing and the bushing 2 (not shown in the figure). The other end of the extension spring 3 is fixedly connected with the inner ring 6 . The contact block 4 is a knife-shaped body. The handle 41 of the knife-shaped body is connected to the inner ring 6 by the positioning shaft 42 in the axial direction. The corresponding position where the block 4 rotates is provided with a groove 51 for the contact block...

Embodiment 2

[0029] As shown in Fig. 3 and Fig. 4, it is the lateral and longitudinal cross-sectional diagram of the clutch of embodiment 2 of the present invention.

[0030] The clutch includes two extension springs 3 arranged radially along the vertical shaft 1, one end of the extension springs 3 is connected to the contact block 4, the outer ring 5 connected to the generator rotor, and the inner ring 6 connected to the vertical shaft sleeve 2, installed The blades on the supporting wing drive the inner ring 6 to rotate with the wind wheel through the connection between the supporting wing and the bushing 2 (not shown in the figure). The other end of the extension spring 3 is fixedly connected to the inner ring 6 . The contact block 4 can expand and contract in the radial direction under the action of the tension spring 3 , and a stopper 8 for the contact block 4 is provided at a corresponding position of the outer ring 5 corresponding to the movement of the contact block 4 . Clutch is ...

Abstract

The present invention relates to an automatic clutch for vertical shaft wind-force power generator. The invented automatic clutch includes the following several components: several extension springs which are radially-arranged along the vertical shaft, contact block connected with one end of extension spring, external ring connected with rotor of power generator and internal ring connected with the vertical shaft. Said invention also provides the concrete working principle of said automatic clutch and its concrete operation method and steps.

Description

technical field [0001] The invention relates to a vertical-axis wind power generator, in particular to an automatic clutch applied to a vertical-axis wind power generator. technical background [0002] In order to make better use of wind energy, people have designed various structural forms of wind power generators for a long time. According to the position of the wind turbine rotation axis in the space direction, it is divided into horizontal axis wind turbines in the horizontal direction and vertical wind turbines in the vertical direction. shaft wind turbine. [0003] According to calculations based on physical principles, the starting torque of lift-type vertical-axis wind turbines is small, while the blades of vertical-axis wind turbines are limited by materials and structures, and the rated speed of the wind rotors is lower than that of horizontal-axis wind turbines. Therefore, in the case of the same output power, the torque required by the vertical axis wind turbine...
