Abstract
The utility model discloses wind electric impeller, comprise blade and wheel hub; Described blade and wheel hub are coordinated by flange to be installed; Described wheel hub front side integral has made an extension; Described extension is provided with draw ring; Described draw ring and blade rear portion are provided with spring; Described spring and hub surface are fitted; Described draw ring both sides are provided with limited ring; Described limited ring is directly welded on extension.Wind electric impeller of the present utility model, when wind scale is larger, the blade tip of fan blade is bent, but due to the support beam of fan blade inside, and the spring action of outside, make it bend excessive, round and smooth inner concave will be set near pylon one side in addition, ensure fan blade self, and structurally reduce the possibility that fan blade and support tower encounter.
Description
Technical field
The utility model relates to wind electric impeller, belongs to wind power equipment technical field.
Background technique
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 realizes the equipment that Wind resource change becomes electric energy, generally includes wind turbine, driving mechanism, generator, automatic controller and support steel tower etc.; The effect of wind turbine is mechanical energy by Wind resource change, and it is contained on wheel hub by 2 ~ 3 blades of aeroperformance excellence and forms, the wind wheel slowly run by transmission system by step-up gear speedup, by transmission of power to generator; According to the difference of generating occasion, the length of blade is also different, large-scale generating occasion, require that length of blade is very long, in order to blade can safe operation, avoid its blade tip to encounter support tower, require that the hardness ratio of blade is higher, but only change its hardness be difficult to meet wind scale higher when.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes wind electric impeller; Structurally can reduce the possibility that fan blade and support tower are encountered.
(2) technological scheme
Wind electric impeller of the present utility model, comprises blade and wheel hub; Described blade and wheel hub are coordinated by flange to be installed; Described wheel hub front side integral has made an extension; Described extension is provided with draw ring; Described draw ring and blade rear portion are provided with spring; Described spring and hub surface are fitted; Described draw ring both sides are provided with limited ring; Described limited 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 is formed; Described extension is provided with bolt hole; Described limited ring is fixed by bolt and extension.
(3) beneficial effect
Compared with prior art, wind electric impeller of the present utility model, when wind scale is larger, the blade tip of fan blade is bent, but due to the support beam of fan blade inside, and the spring action of outside, it is made to bend excessive, round and smooth inner concave will be set near pylon one side in addition, ensure fan blade self, and structurally reduce the possibility that fan blade and support tower encounter.
Accompanying drawing explanation
Fig. 1 is overall structure figure schematic diagram of the present utility model.
Wind electric impeller as shown in Figure 1, comprises blade 1 and wheel hub 2; Described blade 1 and wheel hub 2 are coordinated by flange to be installed; Described wheel hub 2 front side integral has made an extension 3; Described extension 3 is provided with draw ring 4; Described draw ring 4 is provided with spring 5 with blade 1 rear portion; Described spring 5 is fitted with wheel hub 2 surface; Described draw ring 4 both sides are provided with limited ring 6; Described limited 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 is formed; Described extension 3 is provided with bolt hole; Described limited ring 6 is fixed by bolt and extension.
Wind electric impeller of the present utility model, when wind scale is larger, the blade tip of fan blade is bent, but due to the support beam of fan blade inside, and the spring action of outside, make it bend excessive, round and smooth inner concave will be set near pylon one side in addition, ensure fan blade self, and structurally reduce the possibility that fan blade and support tower encounter.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
