Abstract
The utility model relates to an air inflow adjusting device of a ventilation system of a locomotive. The cross section of each guide vane (1) of a shutter is in a Y shape by taking a pivot (5) as the center; a wing (7) positioned at the inner side is hinged with a transmission connecting rod (2); a driving motor can drive the transmission connecting rod (2) to longitudinally shift by a reduction gear (3); and limit switches (4) are arranged at the two ends opposite to the transmission connecting rod (2). When the locomotive is in running, the running direction, the real-time speed and the real-time ventilation pressure value M of the locomotive can be detected; and the opening angle of the guide vanes of the shutter can be adjusted according to the difference between the real-time pressure M and a standard pressure value Q. The opening angle of the shutter as well as the parameters such as the running direction, the speed, the air volume of the locomotive can be controlled together, so as to meet the ventilating requirement of devices in the locomotive when the locomotive is in high-speed running.
Description
Technical field
The utility model relates to the railway locomotive technology, relates in particular to a kind of locomotive ventilation system suction quantity control apparatus.
Background technology
Locomotive mainly is to come equipment such as cooling transformer (oil), current transformer (power model), traction electric machine from the decanter type louver absorbing air outside car on the both walls between locomotive header or machinery through the ventilating set in the car.The decanter type louver is a whole trellis work, and grid blade each several part is fixed.Along with the raising of locomotive running speed, when needs increased the required ventilation volume of cooling intallation, the suction quantity at locomotive louver place can diminish on the contrary.This is that along with the development in flow field, locomotive side, pressure intensity weakens rapidly, will form negative pressure at the locomotive side surface after increasing because of locomotive speed.The increase that square is directly proportional of surface negative pressure and locomotive speed, under the certain situation of traction electric machine cooling blower power, the locomotive engine ventilation volume will reduce.Intake when the power of unit can improve locomotive operation though increase is respectively ventilated, this can increase the energy consumption of locomotive, strengthens the generation of heat.Simultaneously, because the locomotive inner space is limited, high-power ventilation unit is difficult to arrange, and increasing ventilating set power also will increase the locomotive design and manufacture cost.
The utility model content
The purpose of the utility model overcomes the deficiency of above-mentioned prior art exactly; Provide a kind of with louver opening angle and locomotive operation direction, speed, ventilation volume etc. parameter combine unified control, to satisfy locomotive locomotive ventilation system suction quantity control apparatus and control method of the air-conditioning requirement of each equipment in the car when the high-speed cruising.
The purpose of the utility model is achieved in that a kind of locomotive ventilation system suction quantity control apparatus; It is characterized in that; It is the Y type shape of pivot (5) that the cross section of each breather vane (1) of louver is with the mid point; A wing (7) that wherein occupy the inboard is hinged with kinematic link (2), and drive motor can drive kinematic link (2) through reducing gear (3) and vertically move, and the two ends of kinematic link (2) are provided with limit switch (4) relatively.
In order to realize the purpose of the utility model better, the both wings that the cross section of above-mentioned breather vane occupy the outside are the shape that curves inwardly.
The scheme of the utility model with louver opening angle and locomotive operation direction, speed, ventilation volume etc. parameter combine unified control.During locomotive operation; Control system is gathered locomotive service direction signal and speed signal; Judge the blinds opening direction, higher or when applying to rarefaction of air areas such as plateau and cause the ventilation cooling system intake not enough when locomotive speed, be arranged on the interior sensor of water conservancy diversion blinds and the blast letter is fed back to the locomotive microcomputer control system start driving motor automatically and drive kinematic link work then; Face opened by louver and the locomotive operation orientation angle increases gradually, to increase the intake of louver.Under the certain situation of ventilating machinary power, improve fanning effect to greatest extent.

Fig. 1 is the locomotive ventilation system suction quantity control apparatus structural representation of the utility model embodiment.
Fig. 2 is the locomotive running speed of the utility model embodiment and the standard corresponding relation setting process block diagram of ventilating pressure.
Fig. 3 is the control method FB(flow block) of the locomotive ventilation system suction quantity control apparatus of the utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the locomotive ventilation system suction quantity control apparatus of present embodiment, it is the Y type shape of pivot (5) that the cross section of each breather vane (1) of its louver is with the mid point, the both wings (6) that the cross section of breather vane (1) occupy the outside are the shape that curves inwardly.A wing (7) that wherein occupy the inboard is hinged with kinematic link (2), and the drive motor (not shown) can drive kinematic link (2) through reducing gear (3) and vertically move, and the two ends of kinematic link (2) are provided with limit switch (4) relatively.
Referring to Fig. 2, the flow process of the standard corresponding relation of setting locomotive running speed and ventilating pressure is described.Measure the ventilating pressure value Q that under different locomotive running speed situation, obtains desirable cooling performance at frame 11.At frame 1.2 locomotive running speed and the ventilating pressure value Q relation that obtains desirable cooling performance are stored among the CPU.
Referring to Fig. 3, the control flow of locomotive ventilation system suction quantity control apparatus is described.Detect the locomotive service direction at frame 2.1.Detect the locomotive operation real-time speed at frame 2.2.Confirm the cooresponding ventilating pressure standard value of locomotive real-time speed Q at frame 2.3.Detect ventilating pressure instantaneous value M at frame 2.4.At frame 2.5 ventilating pressure instantaneous value M and standard value Q are compared: if M greater than Q, then returns frame 2.1; Otherwise, get into frame 2.6, drive kinematic link and move to the locomotive operation direction, strengthen the opening angle of breather vane, return frame 2.1 then.When the opening angle of breather vane reaches maximum, the limit switch among Fig. 1 (4) action, drive motor quits work.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
