Wind power generation device

Abstract

The invention discloses a wind power generation device. The wind power generation device comprises an electric generator, a right-angle transmission gearbox, a first shaft coupling, a spindle, a windresistance plate, a second shaft coupling and a fixing rack. The electric generator is fixedly connected with the ground. The right-angle transmission gearbox is fixed to the ground and further is intransmission connection with an input shaft of the electric generator. The first shaft coupling is in transmission connection with the right-angle transmission gearbox. The spindle is upright, and thebottom end of the spindle is in transmission connection with the first shaft coupling. The top end of the spindle is connected with the second shaft coupling. The wind resistance plate comprises a bar frame and a wind baffle. The bar frame is fixedly connected with the spindle. The bar frame is provided with an air hole. The top of the wind baffle is in articulated connection with the top of theair hole in a hinged mode, and the bottom of the wind baffle is in control connection with a control valve. The fixing rack comprises shaft sleeves, a triangular support, fixing piles and pulling ropes. The triangular support is fixedly connected with the shaft sleeves. One ends of the pulling ropes are fixedly connected with the triangular support, and the other ends of the pulling ropes are fixedly connected with the fixing piles so as to make the spindle be upright.

Description

Technical field [0001] The invention relates to the field of electric power, in particular to a wind power generation device. Background technique [0002] The wind power generation devices currently in use have high investment costs and long payback periods. The cost payback period is generally more than 15 years, mainly as follows: [0003] 1. The cost of road repairing during installation is high: traditional wind power generation is usually located on the top of a mountain or a place with good vents, especially in the south, where wind power is generally located on the top of the mountain. In the early stage, a wide road must be built first, usually with a four-lane curve. The purpose of winding to the top of the mountain is to transport wind power blades and large cranes that are tens of meters long, causing road repair costs to account for more than 20% of the total project investment; [0004] 2.

AI Technical Summary

Problems solved by technology

[0002] Currently used wind power generation devices have high investment costs and long payback periods. The cost payback period is generally more than 15 years. The main performance is as follows:

[0003] 1. High cost of road construction during installation: Traditional wind power generation is usually located on the top of a mountain or a place with good air outlets, especially in the south. Wind power generation is generally located on the top of a mountain. In the early stage, a wide road should be built first, usually with four lanes of winding The purpose of the winding path to the top of the mountain is to transport wind power blades and large cranes that are tens of meters long, resulting in road construction costs accounting for more than 20% of the total project investment;

[0004] 2. The cost of building the foundation is high: the height of the existing wind power generation on land is between 80 meters and 120 meters. Such a high height must build a super large reinforced concrete base to stabilize the entire wind turbine from being blown by the wind. In fact, it should account for more than 15% of the total investment;

[0005] 3. The installation cost of components is high: traditional wind power generation brackets, machine heads, and blades are all installed with large cranes. Traditional wind turbines require large medium-sized cranes for installation, and the installation cost of each 1,000-kilowatt unit is about 300,000 yuan;

[0006] 4. High operation and maintenance costs: Traditional wind power generation has high operation and maintenance costs. If the machine head is broken or the wind blade is broken, it must be replaced by a large crane. The new wind power generation can complete the replacement of parts without a large crane

[0007] 5. High transportation cost: The blades of existing wind power generation are dozens of meters long, so they need to be transported by special vehicles. They can only drive slowly along the way, and encounter various bad places, such as high-power electric wires and optical cables. , large trees, buildings, etc., need to be coordinated by various departments before they can be passed, resulting in high transportation costs, reaching 5% of the total investment cost
