Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with accompanying drawing, and its content is explanation of the present invention rather than limitation:

[0028] figure 1 The self-protection offshore wind power system with telescopic blades of the present invention mainly includes six major parts: offshore wind power generation sub-system, sensor control system, telescopic power system, supporting foundation system 4, power transmission system 5, and energy storage system 6.

[0029] Specifically, the offshore wind power generation subsystem mainly includes blades 1-1, hubs 1-2, shafts 1-3, gearboxes 1-4, generators 1-5 and nacelles 1-6. Wherein the rotating shaft 1-3, the gear box 1-4 and the generator 1-5 are installed in the nacelle 1-6. The hub 1-2 is connected to the blade 1-1, the two ends of the rotating shaft 1-3 are connected to the hub 1-2 and the gear box 1-4, and the gear box 1-4 is connected to the generator 1-5. When work...

Abstract

The invention discloses a self-protection offshore wind power system with telescopic blades and a working method thereof, and belongs to the technical field of offshore wind power. According to the self-protection offshore wind power system with telescopic blades, a cabin is connected with a supporting foundation, and the supporting foundation is fixed to seabed; a transmission system, a generator, a control system and an energy storage system are arranged in the cabin, blades are connected with a hub, and the hub is connected with the generator through the transmission system; a motor is arranged in the hub and is connected with the blades through a telescopic operating mechanism; each blade comprises a plurality of blade sections which are sequentially nested, and the blade sections can stretch out and draw back through the telescopic operating mechanism; environment sensors are arranged in an external environment and are connected with the control system; and the generator is connected with an electric energy transmission system, the energy storage system is connected with the motor and the electric energy transmission system, and the electric energy transmission system is connected to a power grid. According to the invention, current environment conditions can be intelligently judged and analyzed, and when an extreme environment occurs, the blades are quickly withdrawn, so that the blades are prevented from being injured or damaged due to impact.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to a self-protecting offshore wind power system with telescopic blades and a working method thereof. Background technique [0002] In the past 20 years, driven by the energy crisis of fossil fuels and the pressure of environmental change, renewable new energy has attracted more and more attention around the world. At present, many countries are implementing development strategies such as marine resource development and renewable energy. The development and utilization of offshore wind power will be an important part of the future energy structure. Offshore wind power has also begun large-scale project pre-construction. Offshore wind power technology has begun to be widely used and has great development prospects in the future. [0003] However, due to the relatively harsh offshore environment, when encountering extreme environments, the blades will be strong...
