Description
Technical field
The present invention relates to technical field of generators more particularly to a kind of Power generator fan assemblies.
Background technique
Currently, vapour/diesel-driven generator heat dissipation mainly radiated by fan, and in order to improve fan work during
Safety can all add fan guard on the outside of fan；It is all that blast fan is first installed to alternator shaft in assembling process
On, then fan guard is bolted or is welded and fixed with generator casing again, this reduces the assembly of generator
Efficiency；And in the generator course of work, due to the vibration generated when generator work, it is easy to fan guard be made to loosen or take off
It falls, stability is poor；It even causes fan guard to damage and thus generates mechanical accident and personal injury.In addition, in generator work
Noise can be all generated during work and fan, and the noise generated can be passed through fan and fan guard rapidly, thus
Great noise pollution is caused to environment.
Summary of the invention
In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a kind of Power generator fan assembly, energy
Keep the assembly of generator more quick, to effectively improve the assembly efficiency of generator, and can be effectively reduced generator work
It is polluted caused by the Noise upon Environment generated during making.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that it is such: a kind of Power generator fan assembly,
Including fan guard and blast fan, it is characterised in that: the fan guard is cylindrical in shape structure；The blast fan includes interior connection
Ring, outer connection ring and blade, the inner side and outer side of the blade are fixedly connected with interior connection ring and outer connection ring respectively；Connect inside
The inside for connecing ring is axially arranged with an at least keyway along it；The blast fan is set in fan guard, and outer ring passes through a connection bearing
It is fixedly connected with one end of fan guard, wherein the inner side and outer side of the connection bearing is respectively and in outer connection ring and fan guard
Side is interference fitted together；A ring-shaped rubber pad is equipped on the inside of the other end of fan guard.
Further, the fan guard inner wall between blast fan and rubber pad is provided with soundproof plate, the soundproof plate and wind
It fans cover inner wall to be close to, and around fan guard inner wall one week.
Further, several air inlets are equipped on the fan guard between blast fan and rubber pad, the air inlet
Length direction is consistent with the length direction of fan guard, and the air inlet runs through soundproof plate.
Further, wire mesh is equipped with close to one end of blast fan in fan guard.
Compared with prior art, the present invention has the advantage that structure is simple, fan guard and blast fan are integrated into one
Body can effectively improve the assembly efficiency of generator to make to assemble more convenient；Also, soundproof plate is set in fan guard,
It can be effectively reduced pollution caused by the Noise upon Environment generated in the generator course of work.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Embodiment: referring to Fig. 1, a kind of Power generator fan assembly, including fan guard 1 and blast fan, the fan guard 1 be in
Tubular structure.The blast fan includes interior connection ring 21, outer connection ring 22 and blade 23, the inner side and outer side of the blade 23
It is fixedly connected respectively with interior connection ring 21 and outer connection ring 22；In the inside of interior connection ring 21, an at least key is axially arranged with along it
Slot.
The blast fan is set in fan guard 1, and outer ring is fixedly connected by a connection bearing 3 with one end of fan guard 1,
Wherein, the inner side and outer side of the connection bearing 3 is interference fitted together on the inside of outer connection ring 22 and fan guard 1 respectively.
A ring-shaped rubber pad 4 is equipped on the inside of the other end of fan guard 1.
When it is implemented, 1 inner wall of fan guard between blast fan and rubber pad 4 is provided with soundproof plate 5, the soundproof plate
5 were close to 1 inner wall of fan guard, and around 1 inner wall of fan guard one week；It, can will be in the generator course of work by the way that soundproof plate 5 is arranged
The partial noise generated when partial noise and the blast fan rotation of generation is absorbed, to reduce environment caused by noise
Pollution.On fan guard 1 between blast fan and rubber pad 4 be equipped with several air inlets, the length direction of the air inlet with
The length direction of fan guard 1 is consistent, and the air inlet runs through soundproof plate 5；To keep air-flow more smooth, and in the flowing of gas
The heat generated when generator being worked in the process is taken away.
Wire mesh is equipped with close to one end of blast fan in fan guard 1；To further increase the generator course of work
In safety.
When assembly, it will be set on alternator shaft after the interior connection of blast fan, then the position of mobile fan cover 1,
It is set in the rubber pad 4 of fan guard 1 on generator casing, and forms tight fit with generator casing；Finally again by key with
Blast fan is fixed in the cooperation of keyway, to complete the assembly of entire fan assembly；It is easy for installation, quick, it can effectively mention
The assembly of high generator；Meanwhile fan guard 1 is connected by rubber pad 4 with generator casing, it is convenient without fixing, and again can
Enough reduce the generation of noise.
Finally, it should be noted that technical side the above examples are only used to illustrate the technical scheme of the present invention and are not limiting
Case, those skilled in the art should understand that, modification or equivalent replacement of the technical solution of the present invention are made for those, and
The objective and range for not departing from the technical program, are intended to be within the scope of the claims of the invention.
