Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation blades, in particular to a novel wind power generation blade. Background Art
[0002] Wind is a natural phenomenon on Earth, caused by solar radiation heat. A wind turbine is a power machine that converts wind energy into mechanical energy, also known as a windmill. Broadly speaking, it is an engine that uses the sun as a heat source and the atmosphere as a working medium. The principle of wind power generation is to use wind to drive the blades to rotate, and then increase the speed of rotation through a speed increaser to enable the generator to generate electricity. The design of the blades in a wind turbine directly affects the conversion efficiency of wind energy and its power generation, and is an important part of wind energy utilization.
[0003] The current shape of wind turbine blades is an airfoil blade. This type of blade usually adopts an airfoil design and has a specific curved shape to more efficiently capture wind energy and convert it into electrical energy. However, the airfoil blade has a complex design and high manufacturing and maintenance costs. In the subsequent use process, under extreme weather conditions, the blade is easily damaged, affecting the stability of the unit. Problems such as these arise, and thus a new type of wind turbine blade is designed. Utility Model Content
[0004] In response to the above problems, the present invention provides a new type of wind turbine blade. By welding multiple turbine blades to the fixing rods between the tower connecting rings and sewing a wind cloak to the blade frame to form a closed state, the turbine blade has a larger wind area in the concave state and is more powerful when receiving wind force, thereby better capturing wind energy, transmitting it and converting it into electrical energy.
[0005] To achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a novel wind turbine blade, comprising a generator blade, a blade frame provided within the generator blade, a wind cape sewn onto the blade frame, a plurality of pressure rods welded to the blade frame, a plurality of first clamping plates mounted on the blade frame, a plurality of second clamping plates mounted on the blade frame, an even number of oblique fixing tubes welded to the plurality of first clamping plates, and an even number of cross reinforcement rods connected between the plurality of second clamping plates; a frame plate provided within the blade frame, a spoon-shaped frame welded to each end of the frame plate, a plurality of welded tubes welded between the spoon-shaped frames, a plurality of spoon-shaped cross beams welded below the welded tubes, a plurality of cross frames mounted on the welded tubes and the spoon-shaped cross beams. The cross frames primarily serve to compensate for gaps between the welded tubes and the spoon-shaped cross beams, enabling the cross frames to support the wind cape when the wind cape is sewn, thereby driving the generator blade to rotate in response to the wind.
[0006] Furthermore, the sidewalls of the generator blades are connected to fixing rods, each end of which is welded with a tower connection ring. The tower connection ring is primarily used to be mounted on the steel tower, thereby cooperating with the power generation structure on the steel tower. The tower connection ring is driven by the generator blades to rotate and generate electricity.
[0007] Furthermore, the fixing rod is welded to the frame plate, the compression rod can be welded to the scoop-shaped frame, the first and second clamping plates both pass through the wind hood, and the cross reinforcement rods are cross-welded to a plurality of sets of the second clamping plates. The scoop-shaped frame primarily creates a concave interior of the blade frame, allowing for better wind absorption during loading, resulting in greater power and a larger wind hood area.
[0008] Furthermore, the spoon-shaped crossbeam is used to sew the windproof cape. The blade frame is concave, allowing for better windproofing. The ends of the oblique fixing tubes are welded to the surface of the spoon-shaped frame. The oblique fixing tubes welded to the first chuck and the surface of the spoon-shaped frame can distribute the applied force. Together with the cross-strengthening rods, they ensure the windproof strength of the blade frame, effectively achieving wind load-bearing and transmission.
[0009] Furthermore, a plurality of the power generation blades can be installed on the tower connection ring, and the power generation blades are in a 360° circular shape after installation, and can be stacked in high layers according to actual conditions. Beneficial effects
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] The utility model welds multiple power generation blades to the fixing rods between the tower connecting rings, and sews the wind cape to the blade frame to form a closed state, so that the power generation blades in the concave state have a larger wind area and are more powerful when blown by the wind, thereby better capturing wind energy, transmitting it and converting it into electrical energy. At the same time, compared with the existing airfoil blades, the utility model has a simple design, low manufacturing and maintenance costs, and the blades are not easily damaged, thereby ensuring the stability of the generator set.
[0012] The utility model installs a plurality of power generation blades on the fixed top rods between the tower connection rings so as to form a 360° circular state as a whole. As the construction height of the steel tower is adapted, multiple layers can be stacked and synchronous power generation of multiple components of power generation blades can be achieved.
