Problems solved by technology

Wind power has developed rapidly in my country in recent years, especially in the west and coastal areas of my country; because wind power has the characteristics of cleanness, good environmental benefits, renewable, inexhaustible, short infrastructure period and flexible installation scale , which not only gets the attention of the country, but also makes many enterprises and families see hope; one of the important parts of the wind turbine is the door frame of the wind turbine, which is generally made of thick steel plates in order to ensure the strength. The production method is as follows: Draw lines on the steel plate, then cut and hollow out the interior with a welding machine, and finally use a welding machine to cut the outside into a wind turbine door frame; under normal circumstances, a set of wind turbine door frames can be produced in one day with the above-mentioned process method, and the scrap rate usually reaches 80% %, and the problem that it is easy to deform during transportation and installation has brought great inconvenience to the enterprises that produce and use it; because of its high cost, many small and medium-sized enterprises and enterprises interested in wind power generation Families are discouraged; for large enterprises that mainly produce and operate wind power generation, the high cost seriously restricts their development scale

Abstract

The invention belongs to a wind driven generator door frame and a preparation method thereof. The wind driven generator door frame is formed by connecting two U-shaped steel plates in a butt-joint manner, wherein the length of one side of an opening end of each U-shaped steel plate is greater than that of the other side of the opening end, a groove is respectively formed in two end surfaces of two sides of the opening end of the U-shaped steel plate, and a brace rod is arranged between the U-shaped steel plates. The wind driven generator door frame has advantages of simplicity in structure, reasonability in design, high strength, capability of greatly reducing the cost, capability of remarkably improving the production efficiency and suitability for mass production.

Description

technical field [0001] The invention belongs to the technical field of auxiliary components of wind power generators, and in particular relates to a wind power generator door frame and a preparation method thereof. Background technique [0002] A wind turbine is a power machine that converts wind energy into mechanical work, also known as a windmill. In the early 1970s, due to the energy shortage caused by the oil crisis, people realized the instability and limitation of conventional mineral energy supply, so the search for clean renewable energy has become an important issue in the modern world. , pollution-free natural energy has gained people's attention. Wind power has developed rapidly in my country in recent years, especially in the west and coastal areas of my country; because wind power has the characteristics of cleanness, good environmental benefits, renewable, inexhaustible, short infrastructure period and flexible installation scale , which not only gets the att...
