Abstract
The invention relates to the technical field of fans, in particular to a subway square tray fan, which comprises a motor mounting tray, a motor, an air cylinder and an impeller. The fan is characterized in that a support device is arranged at the air outlet end between the air cylinder and the motor, and comprises a connecting lug plate, a supporting frame, a fixing plate and a fixing bolt, one end of the supporting frame is fixedly connected with the connecting lug plate, the other end of the supporting frame is fixedly connected with the fixing plate, the connecting lug plate is fixedly connected with the inner wall of the air cylinder, and the fixing plate is fixedly connected with a front end cover of the motor through the fixing bolt, so the function of enhancing the integral rigidity of fan is achieved, the easiness in vibration of the subway square tray fan under a high-speed running condition is avoided, and the reliability of the fan is improved. By adopting the structure, the fan has the advantages that the structure is reasonable, the cost is low, the integral rigidity of the fan is improved, the vibration of the fan is reduced, and the like.
Description
Technical field
The present invention relates to 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 motor installation disc, motor, air duct and impeller composition, motor one end is fixedly connected with motor installation disc, the other end is fixedly connected with impeller, outside motor is arranged with air duct, air duct one end is fixedly connected with motor installation disc through connecting cover, the other end is through exhaust outlet socket corresponding with impeller intake grill, its deficiency is: when mounted, the weight of motor and impeller is all born by the motor installation disc that is positioned at motor rear end, cause system stiffness lower, in use, because electrode rotating speed is higher, applying working condition is severe, blower fan very easily produces vibration, affect the reliability of blower fan, thereby further affect the reliability of subway circulation.
Summary of the invention
The object of the invention 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 technical solution adopted for the present invention to solve the technical problems is:
A kind of subway square plate blower fan, comprise motor installation disc, motor, air duct and impeller, it is characterized in that the air opening end between air duct and motor is provided with support device, support device comprises connection otic placode, supporting frame, fixed plate and fixing bolt, supporting frame one end be connected otic placode and be fixedly connected with, the other end is fixedly connected with fixed plate, connecting otic placode is fixedly connected with air duct inwall, fixed plate is fixedly connected with motor front end cover through fixing bolt, reach the effect of strengthening blower fan integral rigidity, thereby ensure that subway square plate blower fan is difficult for producing vibration under high speed operation operating mode, improve the unfailing performance of blower fan.
The present invention due to adopt said structure, have rational in infrastructure, cost is low, improve blower fan integral rigidity, reduce the advantages such as fan vibration.
brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Reference character: motor installation 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, invention is further illustrated:
As shown in Figure 1, the weight of motor 2 and impeller 4 is all born by the motor installation disc 1 that is positioned at motor rear end, impeller and motor have formed a kind of cantilever structure like this, due to blower fan in use, motor speed is higher, on-the-spot Environmental Conditions is severe, and this blower fan structure memory produces vibration, affects the stability of blower fan.
As shown in Figure 2, a kind of subway square plate blower fan, comprise motor installation disc 1, motor 2, air duct 3 and impeller 4, motor installation disc 1, motor 2, structure and the annexation of air duct 3 and impeller 4 are same as the prior art, this does not repeat, it is characterized in that the air opening end between air duct 3 and 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 end be connected otic placode 5 and be fixedly connected with, the other end is fixedly connected with fixed plate 7, connecting otic placode 5 is fixedly connected with air duct 3 inwalls, fixed plate 7 is fixedly connected with motor 2 front covers through fixing bolt 8, reach the effect of strengthening blower fan integral rigidity, thereby ensure that subway square plate blower fan is difficult for producing vibration under high speed operation operating mode, improve the unfailing performance of blower fan, this structural change the single-cantilever structure of original structure, improve the rigidity of system, thereby effectively reduce fan vibration, improve the stability of blower fan.
The present invention due to adopt said structure, have rational in infrastructure, cost is low, improve blower fan integral rigidity, reduce the advantages such as fan vibration.
