Abstract
The invention discloses a design method for a wind farm foundation, which is characterized in that: single wind power generation tower barrel foundations in a wind farm are connected to form a triangular or square or round shape so as to form a reticular structure. Compared with the conventional wind power generation tower barrel foundation technology, the design method has the advantages of higher overturn resistance and stability and the like, so that the total cost of the foundation can be reduced; and the method is easy to operate.
Description
Technical field
The present invention relates to a kind of design method of tower barrel base of wind power plant.Its adopts various types of materials such as reinforcing bar, alloy, reinforced concrete the tower barrel base of the single wind-power electricity generation in the wind power plant to be connected into multiple shapes such as triangle, square, circle to constitute reticular structure, thereby effectively improve the performance on whole wind power plant basis, as resistance to capsizing and stability etc.
Background technique
Wind energy is a kind of renewable energy sources of cleaning, have pollution-free, do not need fuel, do not occupy cultivated land, operating cost is low, advantage such as inexhaustible.Therefore, wind energy is subjected to the favor of countries in the world day by day, and development is swift and violent.The wind resource of China is very abundant, and particularly the wind speed in areas such as northeast, northwest, southwest plateau and offshore islands is bigger, even some places had the time wind speed more than 1/3rd very big in 1 year.Have data to show: the THE WIND ENERGY RESOURCES IN CHINA total amount is 1,600,000,000 kilowatts, and about 10% can be for development and use.2007, the target of wind-powered electricity generation development that " the medium-term and long-term development plan of renewable energy sources " that China formulates is clear and definite was to surpass 5,000,000 kilowatts by 2010, reaches 3,000 ten thousand kilowatts to the year two thousand twenty.Therefore, China's development wind-power electricity generation is very potential, also has good development prospect.
The tower tube of wind power generating set and basis are supported in the high-altitude of 60～100m with wind-driven generator, thereby obtain sufficient, stable wind-force with generating.Yet wind-force can produce great tilting moment and pass in the basis.For example, data shows, blower foundation under the limit wind load situation moment of flexure up to 70000kNm.Therefore, wind-power electricity generation is very high for the requirement on basis, in case toppling appears in the basis, consequence is hardly imaginable so.Existing wind generating unit adopts each tower barrel base independent design substantially, and not contact does not form each other, be unfavorable for resisting wind load, and cost is higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of design method of tower barrel base of wind power plant.
The present invention adopts following technological scheme for achieving the above object:
A kind of wind power plant basic design of the present invention method, it is square or round-shaped to constitute reticular structure to it is characterized in that the single wind power tower drum basis in the wind power plant is connected into triangle.
The material that connects tower barrel base adopts reinforcing bar or reinforced concrete.
Connector element adopts solid construction or hollow-core construction.
The single rod member that can adopt between each tower barrel base connects, and the system that also can adopt a plurality of rod members to constitute connects.
Being connected can adopt between connector element and tower barrel base is rigidly connected, and also can adopt elasticity to connect.
The present invention compares advantages such as having better resistance to capsizing and stability with existing wind power tower drum basic technology, thereby can totally reduce the cost on basis, and easy operating.

Fig. 2 is two tower barrel base connection diagrams in the inventive method wind power plant.
Embodiment
The present invention adopts materials such as reinforcing bar, alloy, reinforced concrete to constitute hollow or solid component connects into a plurality of tower barrel bases in the wind power plant in reticular structures (as shown in Figure 1) such as triangle, square or circle.Being connected can adopt between connector element and tower barrel base is rigidly connected, and also can adopt elasticity to connect.Connection between each tower barrel base can be adopted single rod member, also can adopt rod member system (as truss structure etc.), as shown in Figure 2.
