Problems solved by technology

The above-mentioned technologies have their own characteristics, but there are also shortcomings. The centrifugal pitch technology has high requirements on the speed of the wind rotor, and there are many constraints and disadvantages in practical applications. The ability to adapt to changes in wind direction is poor, and the blade swing control system of umbrella wind turbines is relatively complicated

Abstract

The invention relates to a short-blade multi-rotor wind power generation device. The short-blade multi-rotor wind power generation device comprises a bracket assembly, a rotating arm assembly, a generator, rotor assemblies and a transmission assembly. A rotary pair of the rotary arm assembly is connected to the top of the bracket assembly, the rotor assemblies are symmetrically connected to the front side and the rear side of the rotary arm assembly respectively through rotary pairs, the transmission assembly is arranged in the rotary arm assembly, the transmission assembly is respectively intransmission connection with the rotor assemblies, the generator is fixedly connected in the bracket assembly, and a driving shaft of the generator is coaxially and keyed to the bottom of the transmission assembly. The wind driven generator has the advantages of multiple rotors, short blades, high rotating speed, high efficiency, low lifting frame, light weight, small vibration, safety, stabilityand the like, the six rotor assemblies can be driven to rotate by small wind power, and the generator is driven to generate electricity through transmission of all gears.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a short blade multi-rotor wind power generation device. Background technique [0002] Wind turbines are a typical type of clean energy equipment, widely used in areas with abundant wind resources to generate electricity. In order to increase the wind torque, the blades of wind turbines are usually made longer, so they are called blade single-rotor generators. The existing long-blade single-rotor generator still has the following deficiencies: [0003] 1. The energy loss is large and the life is short. Generally, the rotor speed of the long-blade single-rotor generator is low, while the conventional generator needs to be able to generate electricity efficiently at high speed. It is equipped with a transmission with a large speed-up ratio. Generally, the larger the speed ratio of the transmission, the lower the efficiency, the greater the energy loss and wear, and ...
