Suspension-type horizontal shaft wind generating set

Abstract

The invention discloses a suspension-type horizontal shaft wind generating set based on down-eccentric protection for a communication tower in the technical field of wind power generation. The suspension-type horizontal shaft wind generating set comprises a suspension gear, a wind driven generator, a wind wheel system, a tail vane system and a control system, wherein the suspension gear is fixedly arranged at the outer side of the communication tower, the wind driven generator is connected with the suspension mechanism in a rotating mode, the front end of the wind driven generator is fixedly connected with the wind wheel system, the tail end of the wind driven generator is fixedly connected with the tail vane system, the control system is arranged at the bottom of the communication tower and is connected with the output end of the wind driven generator, and the wind driven generator and the tail vane system are both horizontally arranged in the initial state. The wind generating set of the invention can be suspended on the communication tower so as to save tower cost to install the wind generating set and save space; in addition, the wind generating set of the invention can provide green and clean energy for equipment for a communication base station, saves energy and reduces emission.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a suspended horizontal axis wind power generating set based on downward deflection protection for communication towers. Background technique [0002] Wind power generation is one of the widely used renewable energy sources at present, but there are difficult problems in wind power generation. (1) The magnitude of the wind force varies greatly in nature, and high-speed rotation in strong winds will cause damage to the wind rotor or even burn the wind power generator; (2) ) The wind direction is erratic in nature, how to adjust the wind direction of the wind turbine according to the change of the wind direction. The side deflection of the wind rotor is a form of over-speed protection of the wind rotor in the miniature wind energy conversion system, and it can be summed up in two main structures: the flank type and the eccentric type.

Problems solved by technology

[0006] Due to the many parameters involved in the design of this mechanism, it is not easy to accurately solve the relationship between the various quantities of the parameters. When the aerodynamic force of the wind wheel is sideways, there is still a lack of accurate calculation. They are all random, they are changing all the time, and can produce large changes in a short period of time. The force of the wind wheel is extremely complicated, so the design of this method cannot only stay on theoretical calculations. Experimental testing is still needed, but neither traction table traction test nor wind tunnel test can fully describe the characteristics of wind turbines correctly
