Wind power generation device

Abstract

The invention discloses a wind power generation device, and relates to the technical field of wind power generation. The wind power generation device comprises a cylindrical support rod (1) and a wind driven generator (2) fixed at the top of the bracket (1), and is characterized by at least further comprising a support frame (4) for mounting the support rod (1); the support frame (4) is fixed on the ground; a through hole for penetrating through the support rod (1) is formed in the upper surface of the support frame (4); a protective cover (4) is mounted between the inner wall of the through hole and the support rod (1); a cylinder (5) is used for controlling the support rod (1) to move in the vertical direction; and a piston rod of the cylinder (5) is fixedly connected with the lower end surface of the support rod (1). The support rod can be freely lifted under the acting force of the cylinder, so that maintenance and detection engineers have no need to climb high places, the maintenance and detection efficiency is improved, and the hidden dangers caused by aerial operations to the engineers are prevented.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generation device. Background technique [0002] In recent years, with the rapid development of social industry, the demand for energy is increasing. Since traditional energy sources, such as coal, oil, and natural gas, are non-renewable energy sources, energy issues have become increasingly tense; looking for new energy sources play a pivotal role in human development. [0003] As we all know, wind power is to convert the kinetic energy of wind into electrical energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The wind has been used by people for a long tim...

Problems solved by technology

[0004] Through long-term practice, it has been found that wind power generators mainly rely on wind power to generate electricity. Therefore, wind power generators generally need to be built in open places with relatively abundant wind energy resources. Extreme weather, such as hurricanes or heavy rains, often occurs because of severe weather conditions; once the above-mentioned extreme weather occurs, wind turbines often fail. At the same time, wind turbines also need regular maintenance and inspection, but due to the The poles are generally relatively high, so engineers need to use ladders to climb up for maintenance. The maintenance process is very inconvenient. Therefore, it is particularly important to design and develop a wind power generation device that is easy to maintain and detect.
