Abstract
The utility model relates to a draught fan used for ventilation of a high-speed train. The draught fan comprises a variable frequency motor (1), a supporting structure (2) and blades (3), wherein the variable frequency motor (1) is connected with the supporting structure (2) through fasteners (4), the blades are fixedly connected with the output end of the variable frequency motor (1), and the variable frequency motor (1) is in adjustable and flexible connection with the supporting structure (2). By the adoption of the scheme, after the variable frequency motor is in adjustable and flexible connection with the supporting structure, installing and matching adaptability of the variable frequency motor and the supporting structure can be higher; when a large adjusting range is needed, adjustment can be achieved due to the fact that connecting arms on the supporting structure are arranged in cooperation with a plurality of installation holes formed in different positions; meanwhile, reinforcing ribs on the supporting structure are respectively in a flat iron shape so that the resonance phenomenon of the draught fan and a train vibration source can be effectively avoided.
Description
Technical 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.
