A kind of blower fan ventilating for bullet trainTechnical field
The utility model relates to the Fan Equipment technical field for ventilating, and refers more particularly to a kind of blower fan for ventilating on bullet train.
Background technique
Variable-frequency motor on traditional blower fan is in the installation connection procedure with supporting structure, supporting structure is all by being rigidly connected between fastening piece and variable-frequency motor, for large batch of blower fan production and assembly, the boundary dimension of supporting structure and variable-frequency motor need guarantee higher machining accuracy, just can adapt to this uncontrollable mode that is rigidly connected; And the blower fan on bullet train is generally in the larger working environment of vibration frequency, it is particularly important that the equilibrium problem of himself seems, therefore makes blower fan just seem particularly important in a best working position.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of blower fan for ventilating on bullet train reasonable in design, adjustable is provided.
For achieving the above object, technological scheme provided by the utility model is: a kind of blower fan ventilating for bullet train, comprise variable-frequency motor, supporting structure and fan blade, wherein said variable-frequency motor is connected with supporting structure by fastening piece, described fan blade and variable-frequency motor output terminal are fixedly linked, between described variable-frequency motor and supporting structure for adjustable flexibility is connected.
Further, link arm one end that described flexibility is connected to supporting structure is installed in the mounting groove that described variable-frequency motor outside is provided with by fastening piece.
Further, in described supporting structure, be also provided with the mounting hole of a plurality of diverse locations of installing for the described link arm the other end.
Further, between the adjacent link arm in described supporting structure, be also provided with stiffening rib.
Further, the mounting groove that described variable-frequency motor is provided with is and the one-body molded making of variable-frequency motor shell.
Further, described stiffening rib is band iron shape.
The utility model is after having adopted such scheme, variable-frequency motor by and supporting structure between adopt after adjustable flexible connecting structure, can be so that both installations coordinate adaptability stronger, when the larger adjustment range of needs, can also install to coordinate to realize by the link arm in supporting structure and the mounting hole of a plurality of diverse locations that are provided with and adjust, the stiffening rib in supporting structure adopts band iron shape can effectively avoid blower fan and train vibration source to produce resonance phenomenon simultaneously.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Referring to accompanying drawing 1 to shown in accompanying drawing 4, a kind of blower fan ventilating for bullet train described in the present embodiment, this blower fan comprises the fast variable-frequency motor 1 of an electrodeless modified tone, supporting structure 2 and fan blade 3.Fan blade 3 dismoutabilities are fixedly installed on the output shaft of variable-frequency motor 1, between variable-frequency motor 1 and supporting structure 2, by adjustable flexible connecting structure is fastening, be connected, concrete, in the present embodiment, on this variable-frequency motor 1 surrounding shell, interval is furnished with four and the integrated vertical mounting groove 101 of motor housing, the connecting end of four link arms 201 in these four mounting grooves 101 and supporting structure 2 links together by four fastening piece 4 secure fit respectively, when variable-frequency motor 1 is linked and packed with supporting structure 2, link arm 201 can move to regulate definite mounting point according to actual conditions along mounting groove 101 up/down flexibly.In the present embodiment, each fastening piece 4 is comprised of bolt 401, nut 402 and a plate 403, and wherein connecting plate 403 is fixedly linked with the connecting end of four link arms 201 respectively, can be by welding or one-body molded making, not to be limited.Simultaneously in order to make blower fan there is larger controllability, on bearing structure 2 bodies, be also provided with multicomponent not for the mounting hole 202 of the diverse location installed with these link arm 201 the other ends, wherein every group of mounting hole 202 includes the position, hole of a plurality of diverse locations.
Simultaneously in order to improve the working life of blower fan, in supporting structure 2, between adjacent link arm 201, be also provided with stiffening rib 203, for fear of blower fan and train vibration source, produce resonance phenomenon, in the present embodiment, stiffening rib 203 adopts band iron shape profile, can effectively evade blower fan and train resonates, thereby improve the working environment of blower fan, improve its working life.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
