Description
Technical field
The present invention relates to self-ventilated machines, specially the open-type self-ventilated machine of Anti-ice-and-snow intrusion.
Background technique
Open-type self-ventilated machine includes: motor air outlet, Centrifugal Cooling Fan, motor inner ventilation road, motor into
Air port；The end cap of motor outlet air end or the side of frame shell is arranged in air outlet, opposite with the flabellum of Centrifugal Cooling Fan
Setting, Centrifugal Cooling Fan provide power for the circulation of cooling air；Motor inner ventilation road is cooling airflow through in motor
The wind path in portion is arranged, and generally includes: air gap and rabbet channel, rotor axial direction channel between tones, stator and rotor,
During cooling airflow is through motor inner ventilation road, the heat generated in motor operation can be effectively taken away, plays effective cooling
The effect of motor；The air inlet of motor is generally arranged at electric machine stand shell upper end, and air inlet is installed dust filtration device, can be prevented cold
But the foreign matters such as dust in wind enter motor.
Opposite with open-type self-ventilated machine is enclosed self-ventilation motor, and enclosed self-ventilation motor is by cooling air quantity
Reduced influence, cooling effect are lower than open-type self-ventilated machine.
Use of the traction electric machine of open-type self-ventilation cooling structure in urban rail transit vehicles has obtained considerable
Development.Under wind and snow, psychro-environment, in particular for the motor of bogie suspension installation, in motor operation, ice and snow is easily sealed
Stifled motor dirt catcher, causes motor cooling wind to cannot be introduced into motor and is effectively radiated；If ice and snow enters inside motor, can damage
Motor insulation, to accelerate the adverse consequences such as insulation system aging or even ground fault.
Summary of the invention
The present invention solves the problems, such as that ice and snow easily blocks the dirt catcher of open-type self-ventilated machine, provides a kind of improved anti-
The open-type self-ventilated machine of ice and snow intrusion.
The present invention is achieved by the following technical scheme: Anti-ice-and-snow intrusion open-type self-ventilated machine, motor into
It is connected with air inlet wind guide channel on air port, at least one baffle, the bottom of baffle lower end and air inlet wind guide channel are equipped in air inlet wind guide channel
Portion is fixed, and the top of baffle upper end and air inlet wind guide channel keeps gap.Particulate matter in cooling air is along air inlet wind guide channel flowing
In the process, under the effect of gravity, be piled up in front of baffle by baffle (windward one side), thus realize effectively stop into
The a small amount of dust or ice and snow of air inlet duct enter motor.
Further, the air intake for entering the wind wind guide channel extends outward the air inlet of air duct of section flaring, air inlet of air duct
Bottom is inclined-plane.Heavy caliber air inlet of air duct can reduce wind speed and wind pressure, make particulate matter in cooling air under the effect of gravity
It falls, and is slid along the bottom bevel of air inlet of air duct, realize further dust filtering.
The present invention configures air inlet wind guide channel to open-type self-ventilated machine, by the way that baffle is arranged in air inlet wind guide channel and has
The heavy caliber air inlet of air duct on inclined-plane achievees the purpose that dust, ice and snow is effectively prevent to enter motor from motor air inlet；Motor goes out
Air port wind pressure is larger, and external wind and snow cannot be introduced into inside motor.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is usage state diagram of the invention.
In figure: 1- motor air outlet, 2- Centrifugal Cooling Fan, 3- motor inner ventilation road, 4- motor air inlet, 5- gear
Plate, the inclined-plane 6-, the air duct 7- clean window board, 8- skirtboard, and 9- enters the wind wind guide channel, 10- air inlet of air duct.
Specific embodiment
The open-type self-ventilated machine of Anti-ice-and-snow intrusion is connected with air inlet wind guide channel 9 in motor air inlet 4, and air inlet is led
At least one baffle 5 is equipped in air duct 9,5 lower end of baffle and the bottom of air inlet wind guide channel 9 are fixed, 5 upper end of baffle and air inlet wind-guiding
The top in road 9 keeps gap.The air intake of air inlet wind guide channel 9 extends outward the air inlet of air duct 10 of section flaring, air duct into
The bottom in air port 10 is inclined-plane 6.When it is implemented, the section of air inlet wind guide channel 9 is rectangle, air inlet of air duct 10 is straight in bottom surface
The trapezoidal quadrangular shape in angle and lower bottom side are air intake, upper bottom side be with the outlet air end that docks of air inlet wind guide channel 9, air duct into
The straight waist side in air port 10 is flushed with the top of air inlet wind guide channel 9, so that the oblique waist side of air inlet of air duct 10 becomes its bottom
Inclined-plane 6, in this way, can make enter the wind wind guide channel 9 more compact structure, be easy to use installation.Air inlet of air duct 10 air intake (under
Bottom side) area be to enter the wind 4-8 times of 9 longitudinal section area of wind guide channel, sufficiently to reduce the wind speed and wind pressure of air inlet.
Baffle 5 is tilted to side windward, more fully to realize barrier functionality.Meeting positioned at baffle 5 is provided in air inlet 9 bottom surface of wind guide channel
The air duct of wind side cleans window, and air duct cleans the air duct that is provided with and can be opened and closed on window and cleans window board 7, and air duct is opened in timing
The dust foreign matter of 7 pairs of window board accumulations herein is cleaned to be purged.When it is implemented, air duct cleans 7 one end of window board and air inlet
The bottom surface of wind guide channel 9 is hinged, and the other end is equipped with buckle, realizes that air duct cleans the opening and closing of window board 7 with this.In use, this is anti-icing
The open-type self-ventilated machine for avenging intrusion is used for urban rail transit vehicles as traction electric machine, and air inlet wind guide channel 9 is fixed on vehicle
Its skirtboard 8 is arranged in in the vehicle arrangement storehouse of air filtering function in body bottom, air inlet of air duct 10.In this way, cooling wind into
Have three-level dust filtering before entering motor: 10 position of air inlet of air duct is arranged in vehicle arrangement storehouse, passes through the skirt of vehicle arrangement storehouse side
Plate 8 implements level-one dust filtering；By having the heavy caliber air inlet of air duct 10 on inclined-plane 6, second level dust filtering is realized；By twice baffle 5,
Realize three-level dust filtering.Bigbore air inlet of air duct 10 can effectively reduce the wind speed and wind pressure of air inlet, can effectively reduce into
The noise at air port position, distance 2-3m between air inlet of air duct 10 and the open-type self-ventilated machine of Anti-ice-and-snow intrusion, can prevent
The only superposition of air inlet noise and motor air outlet noise achievees the purpose that reduce ventilating system noise.
