Abstract
The invention discloses a wind power impeller, which comprises blades and a hub, wherein the blades and the hub are installed in a matching way through a flange; an extended section is integrally formed at the front side of the hub; a pull ring is arranged on the extended section; springs are arranged on the rear parts of the pull ring and the blades; the springs are fitted with the surface of the hub; limit rings are arranged at two sides of the pull ring, and are directly welded on the extended section. According to the wind power impeller provided by the invention, when a wind scale is larger, the blade tips of the blades are bent, but due to actions of support beams inside the blades and outside spring functions, the blade tips of the blades cannot be bent excessively; in addition, the face, close to a tower, is arranged to be a smooth inner concave surface, so that the blades are ensured, and the possibility that the blades touch the support tower is reduced structurally.
Description
Technical field
The present invention relates to a kind of wind electric impeller, belong to wind power equipment technical field.
Background technology
Wind power technology equipment is the important component part of Wind Power Generation Industry, also be basis and the guarantee of Wind Power Generation Industry development, wind power generating set is to realize wind energy and convert to the equipment of electric energy, generally includes wind turbine, transmission mechanism, generator, automaton and supports steel tower etc.; The effect of wind turbine is that wind energy is converted to mechanical energy, and it is contained on wheel hub and is formed by 2 ~ 3 blades of aeroperformance excellence, and the wind wheel slowly running by step-up gear speedup, passes to generator by power by transmission system; According to the difference of generating occasion, the length of blade is also different, large-scale generating occasion, require length of blade very long, can safe operation for blade, avoid its blade tip to encounter support tower, require the hardness ratio of blade higher, be difficult to meet in the situation that wind scale is higher but only change its hardness.
Summary of the invention
(1) technical problem that will solve
For addressing the above problem, the present invention proposes a kind of wind electric impeller; Can structurally reduce the possibility that fan blade and support tower are encountered.
(2) technical scheme
Wind electric impeller of the present invention, comprises blade and wheel hub; Described blade coordinates installation with wheel hub by flange; Described wheel hub front side has been made into integration an extension; On described extension, be provided with draw ring; Described draw ring and blade rear portion are provided with spring; Described spring and hub surface laminating; Described draw ring both sides are provided with spacing ring; Described spacing ring is directly welded on extension.
Further, the blade tip of described blade is set to round and smooth inner concave near pylon one side.
Further, described draw ring is made up of bearing; Described bearing surface has been made into integration snap close.
Further, described extension can also be that glass steel material forms; On described extension, be provided with bolt hole; Described spacing ring is fixed by bolt and extension.
(3) beneficial effect
Compared with prior art, wind electric impeller of the present invention, in the time that wind scale is larger, the blade tip of fan blade is bent, but due to the brace summer of fan blade inside, and outside spring action, make it can be bending not excessive, be set to round and smooth inner concave near pylon one side in addition, ensure fan blade self, and structurally reduce the possibility that fan blade and support tower are encountered.
Brief description of the drawings
Fig. 1 is overall structure figure schematic diagram of the present invention.
Wind electric impeller as shown in Figure 1, comprises blade 1 and wheel hub 2; Described blade 1 coordinates installation with wheel hub 2 by flange; Described wheel hub 2 front sides have been made into integration an extension 3; On described extension 3, be provided with draw ring 4; Described draw ring 4 is provided with spring 5 with blade 1 rear portion; Described spring 5 and wheel hub 2 surface laminatings; Described draw ring 4 both sides are provided with spacing ring 6; Described spacing ring 6 is directly welded on extension 3.
The blade tip of described blade 1 is set to round and smooth inner concave 7 near pylon one side.
Described draw ring 6 is made up of bearing; Described bearing surface has been made into integration snap close 8.
Described extension 3 can also be that glass steel material forms; On described extension 3, be provided with bolt hole; Described spacing ring 6 is fixed by bolt and extension.
Wind electric impeller of the present invention, in the time that wind scale is larger, the blade tip of fan blade is bent, but due to the brace summer of fan blade inside, and outside spring action, make it can be bending not excessive, be simultaneously set to round and smooth inner concave near pylon in addition, ensure fan blade self, and structurally reduce the possibility that fan blade and support tower are encountered.
Embodiment recited above is described the preferred embodiment of the present invention, not the spirit and scope of the present invention is limited. Do not departing under the prerequisite of design concept of the present invention; various modification and improvement that this area ordinary person makes technical scheme of the present invention; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, has all been documented in claims.
