Problems solved by technology

[0004] 1. The weight is heavy, because the gearbox 3' is more than 50 tons, and the inverter 5' is more than ten tons, close to more than 60 tons, resulting in a large weight of the fan and high manufacturing costs of the foundation equipment of the fan
[0005] 2. There are many components, because the existing structure needs to use the gearbox 3' and the inverter 5', both of which are large components, and are the two components that are most prone to problems in the fan. Due to the large number of components, lead to reduced reliability
[0006] 3. The quality of power generation is not good. Since the hub 2' and the gearbox 3' are rigidly connected, once the input fluctuates, it will affect the input end of the generator, and the quality of power generation will be unstable

Abstract

The invention relates to a fan. The fan comprises a blade, a hub connected with the blade, a hydraulic transmission mechanism and a synchronous generator, wherein the blade is arranged on the hub; the input end of the hydraulic transmission mechanism is connected with the output end of the hub; and the output end of the hydraulic transmission mechanism is connected with the synchronous generator. The original gear box is replaced by the hydraulic transmission mechanism, so that the power generation frequency of the synchronous generator is 50Hz, inversion is avoided, direct Internet surfing is realized, and the fan has the advantages of light weight, a few parts and high reliability and power generation quality.

Description

technical field [0001] The invention relates to a fan, in particular to a fan with hydraulic transmission. Background technique [0002] see figure 1 , the figure shows the fan structure in the prior art, including sequentially connected blades 1', hub 2', gearbox 3', asynchronous generator 4', inverter 5', and blades 1' are installed on the hub 2' , the wheel hub 2' drives the gear box 3' to rotate, and the gear box 3' speeds up and then drives the asynchronous generator 4' to generate alternating current through the inverter 5'. [0003] The current fan structure has the following disadvantages: [0004] 1. The weight is heavy, because the gear box 3' is more than 50 tons, and the inverter 5' is more than ten tons, close to more than 60 tons, resulting in a large weight of the wind turbine and high manufacturing costs of the foundation equipment of the wind turbine. [0005] 2. There are many components, because the existing structure needs to use the gearbox 3' and the...
