Abstract
The utility model discloses draught fan impellers, belong to wind turbine technical field.This draught fan impeller solves the problems, such as that original fan impeller structure is unstable.This draught fan impeller includes pedestal and the fan blade that is distributed in around pedestal, and pedestal and fan blade are an integral structure, and the material of pedestal and fan blade is aluminium alloy, and pedestal includes shaft annular in shape and the interconnecting piece that is connected on the outside of shaft, and fan blade is connected on the outside of interconnecting piece.This draught fan impeller compared with the prior art, is molded, therefore its structure is relatively stable since pedestal and fan blade are an integral structure, and for aluminium alloy compression casting.
Description
Technical field
The utility model belongs to wind turbine technical field, is related to a kind of draught fan impeller.
Background technology
Traditional draught fan impeller is made of multiple cold stamping hardware components, and material takes iron plate cold stamping, aluminium sheet cold
The techniques manufactures such as punching press, welding combination.If but the draught fan impeller of this structure operates for a long time under special border, is easy to happen leaf
The problems such as piece deforms.In addition, the metal object or handstone of the iron flake sucking that works under high concentrate dust environment are held when getting to blade
It is also easy to produce spark, causes dust explosion, therefore, use environment model is small.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that a kind of wind turbine of stable structure
Impeller.
The purpose of this utility model can be realized by following technical proposal：
Draught fan impeller, including pedestal and the fan blade that is distributed in around pedestal, which is characterized in that the pedestal and fan blade be
The material of integral structure, the pedestal and fan blade is aluminium alloy, and the pedestal includes shaft and connection annular in shape
Interconnecting piece on the outside of shaft, the fan blade are connected on the outside of interconnecting piece.
In this draught fan impeller, since pedestal and fan blade are an integral structure, on the one hand reduce assembly process so that raw
It is higher to produce efficiency, on the other hand, but also the structural integrity of pedestal and fan blade as a whole is preferable, improves draught fan impeller
Structural stability.In addition, the material of pedestal and fan blade is aluminium alloy, but also draught fan impeller in use, is not likely to produce
Spark, use is safer, and use scope is wide.
In above-mentioned draught fan impeller, reinforcing rib is equipped between the shaft and interconnecting piece.
Due to being provided with reinforcing rib between shaft and interconnecting piece, on the one hand so that draught fan impeller lighter in weight, another
Aspect also ensures that fan impeller structure is stablized.
In above-mentioned draught fan impeller, there is groove perpendicular to shaft axis and in a strip shape in the shaft.
The setting of groove facilitates machine shaft to be inserted into rear pin shaft positioning so that draught fan impeller uses more convenient.
In above-mentioned draught fan impeller, multiple balance holes are evenly distributed on the interconnecting piece.
In the production process of draught fan impeller, due to various factors, the weight at each position of draught fan impeller is difficult to reach
Therefore balance hole is arranged in holohedral symmetry on interconnecting piece, in debugging process, can be injected in balance hole with constant weight
Object.
In above-mentioned draught fan impeller, the pedestal and fan blade are die cast as a whole.
In above-mentioned draught fan impeller, the quantity of the fan blade is seven and is evenly distributed on around pedestal.
This draught fan impeller compared with the prior art, since pedestal and fan blade are an integral structure, and for aluminium alloy compression casting at
Type, therefore its structure is relatively stable.

Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As depicted in figs. 1 and 2, this draught fan impeller includes pedestal 1 and the fan blade being distributed in around pedestal 12.In the present embodiment
In, the quantity of fan blade 2 is seven and is evenly distributed on around pedestal 1.Pedestal 1 and fan blade 2 are an integral structure, pedestal 1 and wind
The material of leaf 2 is aluminium alloy, and passes through die cast.
Wherein, pedestal 1 includes shaft 11 annular in shape and the interconnecting piece 12 for being connected to 11 outside of shaft, and fan blade 2 connects
It is connected on 12 outside of interconnecting piece.Reinforcing rib 15 is equipped between shaft 11 and interconnecting piece 12.Due in shaft 11 and interconnecting piece 12
Between be provided with reinforcing rib 15, on the one hand so that draught fan impeller lighter in weight, on the other hand, also ensure that fan impeller structure is steady
It is fixed.
There is groove 13 perpendicular to 11 axis of shaft and in a strip shape in shaft 11.The setting of groove 13, facilitates electricity
Machine shaft positions after being inserted into so that draught fan impeller uses more convenient.
Multiple balance holes 14 are evenly distributed on interconnecting piece 12.In the production process of draught fan impeller, due to various factors,
The weight at each position of draught fan impeller is difficult to reach full symmetric, therefore, balance hole 14 is arranged on interconnecting piece 12, was debugging
Cheng Zhong can inject the object with constant weight in balance hole 14.In the present embodiment, in debugging process, in balance hole 14
Tin after the middle the desired amount of thawing of injection.After cooling, tin generates balanced action in balance hole 14 so that draught fan impeller rotates more
For stabilization.
In this draught fan impeller, since pedestal 1 and fan blade 2 are an integral structure, on the one hand reduce assembly process so that
Production efficiency is higher, on the other hand, but also the structural integrity of pedestal 1 and fan blade 2 as a whole is preferable, improves wind turbine leaf
The structural stability of wheel.In addition, the material of pedestal 1 and fan blade 2 is aluminium alloy, but also draught fan impeller is in use, no
It is also easy to produce spark, use is safer, and use scope is wide.
