Abstract
The utility model relates to the technical field of fans, in particular to a subway square-plate fan comprising a motor mounting plate, a motor, an air tube and an impeller. The subway square-plate fan is characterized in that an air outlet end between the air tube and the motor is provided with a support device, the support device comprises connecting lug plates, supports, fixed plates and fastening bolts, one end of each support is fixedly connected with one connecting lug plate, the other end of each support is fixedly connected with the fixed plat, the connecting lug plates are fixedly connected with the inner wall of the air tube, and the fixed plates are fixedly connected with a motor front end cover through the fastening bolts. Therefore, overall rigidity of the fan is enhanced, the subway square-plate fan is prevented from easily vibrating under the condition of high-speed operation, and reliability of the fan is improved. The subway square-plate fan has the advantages of reasonable structure, low cost, higher fan rigidity, lower fan vibration and the like.
Description
Technical field
The utility model relates to the blower fan technical field, specifically a kind of subway square plate blower fan.
Background technique
At present, subway square plate blower fan is subway airport a kind of blower fan that uncolled braking resistor is used in running, this blower fan is by the motor mounting disc, motor, air duct and impeller are formed, motor one end is fixedlyed connected with the motor mounting disc, the other end is fixedlyed connected with impeller, the motor outer cover is provided with air duct, air duct one end is fixedlyed connected with the motor mounting disc through connecting cover, the other end is through exhaust outlet and the corresponding socket of impeller intake grill, its deficiency is: when mounted, the weight of motor and impeller is all born by the motor mounting disc that is positioned at motor rear end, causes system stiffness lower, in use, because the electrode rotating speed is higher, applying working condition is abominable, and blower fan very easily produces vibration, influence the reliability of blower fan, thereby further influence the subway reliability of operation.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, cost is low, improve blower fan integral rigidity, reduce the subway square plate blower fan of fan vibration.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of subway square plate blower fan, comprise the motor mounting disc, motor, air duct and impeller, it is characterized in that the air opening end between air duct and the motor is provided with support device, support device comprises the connection otic placode, supporting frame, fixed plate and fixing bolt, supporting frame one end is with to be connected otic placode fixedly connected, the other end is fixedlyed connected with fixed plate, connecting otic placode fixedlys connected with the air duct inwall, fixed plate is fixedlyed connected with the motor front cover through fixing bolt, reach the effect of strengthening the blower fan integral rigidity, thereby guaranteed that subway square plate blower fan is difficult for producing vibration under the high speed operation operating mode, improved the unfailing performance of blower fan.
The present invention is owing to adopt said structure, have rational in infrastructure, cost is low, improve blower fan integral rigidity, reduce advantage such as fan vibration.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is structural representation of the present utility model.
Reference character: motor mounting disc 1, motor 2, air duct 3, impeller 4, connection otic placode 5, supporting frame 6, fixed plate 7, fixing bolt 8.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 1, the weight of motor 2 and impeller 4 is all born by the motor mounting disc 1 that is positioned at motor rear end, impeller and motor have formed a kind of cantilever structure like this, because blower fan in use, motor speed is higher, on-the-spot Environmental Conditions is abominable, and this blower fan structure memory produces vibration, influences the stability of blower fan.
As shown in Figure 2, a kind of subway square plate blower fan, comprise motor mounting disc 1, motor 2, air duct 3 and impeller 4, motor mounting disc 1, motor 2, structure and the annexation of air duct 3 and impeller 4 are same as the prior art, this does not give unnecessary details, it is characterized in that the air opening end between air duct 3 and the motor is provided with support device, support device comprises connection otic placode 5, supporting frame 6, fixed plate 7 and fixing bolt 8, supporting frame 6 one ends are with to be connected otic placode 5 fixedly connected, the other end is fixedlyed connected with fixed plate 7, connect otic placode 5 and fixedly connected with air duct 3 inwalls, fixed plate 7 is fixedlyed connected with motor 2 front covers through fixing bolt 8, reaches the effect of strengthening the blower fan integral rigidity, thereby guaranteed that subway square plate blower fan is difficult for producing vibration under the high speed operation operating mode, improved the unfailing performance of blower fan, this structural change the single-cantilever structure of original structure, improved the rigidity of system, thereby effectively reduced fan vibration, improved the stability of blower fan.
The present invention is owing to adopt said structure, have rational in infrastructure, cost is low, improve blower fan integral rigidity, reduce advantage such as fan vibration.
