DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a diesel electric locomotive.

[0002]

2. Description of the Related Art In a diesel electric locomotive, there is no partition in a machine room between a partition wall of a driver's cab on one side of a vehicle body and a partition wall of a driver's cab on the other side. Some outside air for cooling the motor is directly taken in from an air filter provided on an outer plate of a vehicle body.

[0003] In addition, although an independent room in which a radiator is arranged is provided, a main converter, an auxiliary power supply, and a main blower are arranged in a common machine room opened together with an engine and a main generator. is there. In this case, in every machine room, an air filter and a louver are provided on the outer plate of the vehicle body, and air is taken directly from the air filter and the louver provided on the outer plate of the vehicle body in each room.

On the other hand, in a DC, AC or AC / DC electric locomotive, a resistor room is provided in a machine room, and wind distributed from a main blower is guided to the resistor room to be exhausted from a rooftop garland ventilator. Although this method has been adopted, this method merely provides a resistor room in the machine room, and does not partition the vehicle body.

There is also an electric locomotive in which the periphery of the high-voltage equipment frame is surrounded by a door or a cover. This also has a machine room in which a unit switch, a reverser, a PB converter and the like are provided. is there.

However, a main resistor, a main blower, a motor generator and an air compressor are arranged in a second machine room substantially at the center of the vehicle body, and a high-speed circuit breaker, a unit switch, a cam switch, a reverser, etc. There is an example where it is arranged in a machine room.

[0007] Since the equipment in the third machine room does not need to be cooled, there is no air filter or louver on the outer panel of the vehicle body in that room, and the adjacent second machine room and the operation cabs at both ends are separated from the partition walls. It is completely separated by a door.

FIG. 11 is a partial longitudinal sectional view showing an example of a conventional diesel electric locomotive.
FIG. 2 is a diagram showing a control device room in which a control device 1 for controlling the control is stored on both sides of a central passage 28.

In FIG. 11, a central passage 28 is formed between the control device 1 and the power supply device 2, and an exhaust flange formed at the upper end of the control device 1 is formed in a substantially J-shape. The base end of the exhaust duct 24 is connected, and the distal end of the exhaust duct 24 protrudes from one side of the ceiling of the vehicle body.

Below the floor of the control device 1, there is shown an air duct 23 for supplying cooling air supplied from a main blower mounted in another place to the inside of the control device 1. Electrical unit 26 housed inside so that it can be pulled out freely
Are indicated by broken lines.

In order to inspect the electric component unit 26, the electric unit 26 is drawn out to the central passage 28 as shown by an arrow, and then is carried by a plurality of workers to the driver's cab at the end of the vehicle. From the outside.

[0012]

However, in the diesel electric locomotive configured as described above, the second machine room is provided with a device such as a main resistor and a main blower that takes in a large amount of outside air. In spite of these being large noise sources, they take in the outside air directly from the air filters and louvers provided on the outer plate of the vehicle body in the second machine room.

Therefore, by dividing the machine room by a plurality of partition walls and arranging the noise source in the room at the center of the vehicle body, the noise transmitted to the cab can be reduced, but the noise emitted outside the vehicle is reduced. Can not.

As described above, in an electric locomotive, a diesel electric locomotive, or a liquid diesel locomotive, when a machine room is partitioned by a plurality of partition walls and outside air is taken into the vehicle, the room is not used. An air filter and a louver must be provided on the outer plate of the car body, and it must be taken directly.

Further, the diesel electric locomotive is equipped with a variable frequency variable voltage main converter for controlling the main motor and a stationary auxiliary power supply for auxiliary equipment, so that the unit is particularly deep and heavy. Has become.

However, even if the width of the vehicle body is suppressed at the vehicle limit, a central passage is provided on the center side of the vehicle body in order to secure a space in the locomotive for drawing out the unit for maintenance and inspection. The main converter and auxiliary power supply are arranged on both sides of the vehicle body. On the other hand, in high-speed trains such as long-distance limited express trains, the size of the diesel engine is large and the size of the radiator is also large.

For this reason, there is an example in which the radiator is mounted on the roof of the vehicle body and also serves as the roof of the vehicle body. However, in order to mount a large radiator, it is necessary to increase the strength of the pillar structure of the vehicle body. In order to support the radiator with only the long beams of the rafters, the strength of these rafters and the long beams must be increased, so that the weight of the vehicle body increases. Then, not only is the center of gravity of the vehicle body raised and the stability is impaired, but it is not possible to meet the demand for lightening for high speed.

As described above, in the conventional diesel electric locomotive, a device that takes in outside air from outside the vehicle and cools it,
In particular, the engine and main blower are large noise sources.However, when they are placed in an open machine room or in a partitioned machine room, the air filters and louvers on the outer panel of the body of the machine room Since it takes in outside air directly, it emits noise directly outside the vehicle. The same applies when the radiator is arranged in the machine room.

When the engine, the main generator and the main blower are housed in the opened machine room, the main blower inhales the internal air which has risen due to the heat generated from the engine and the main generator in the midsummer, so that The cooling effect of the main equipment such as the converter is reduced.

Conversely, in the configuration in which outside air is directly taken in by the main blower during the snowfall period, the air filter becomes clogged in wet snow unless the flow rate of outside air taken in by the air filter on the outer plate of the body of the machine room is reduced. Insufficient air volume reduces the cooling effect.

On the other hand, even if it is not wet, the powdered snow flows through the filter material of the air filter, so that if the flow rate of the outside air is not greatly reduced, the powder will enter the main motor or the main conversion device, and resist insulation. Reduces voltage characteristics.

Therefore, conventionally, a method of increasing the area of the vehicle-side filter has been adopted in order to reduce the flow velocity through the air filter. However, since the intake air from the air filter at the shortest position becomes large, the intake air of the blower increases. Even if an air filter or louver with a large area is installed as a whole machine room, the outside air mixed with snow and rain is sucked in at a high flow rate from the nearest air filter, and the withstand voltage characteristics of the above-described insulating surface are reduced. .

When the engine, the main generator and the main blower are arranged alone or in combination in a partitioned machine room to suppress noise outside the vehicle, the room temperature rises only due to the heat generated by the engine and the main generator. However, since the cooling air from the main blower decreases, the temperature of the cooling air also increases.

Therefore, in order to suppress noise emitted to the outside of the vehicle, the area of the air filter must be reduced. Then, the flow rate of the intake air increases, and the temperature rises due to a decrease in the amount of intake air due to clogging of the air filter. Becomes
Reducing the amount of noise emission, increasing the cooling effect, and maintaining the insulating properties are inconsistent.

In order to prevent snow and raindrops from entering, a method of providing a drainer or the like is also conceivable. However, this method also has an adverse effect because it increases the pressure loss of the intake outside air. On the other hand, if a passage is provided in the center of the vehicle to increase the size of the unit, especially the unit with increased depth from the main converter or auxiliary power supply, the extracted unit is lowered from the locomotive to the ground, The work to carry in requires labor.

When this passage is provided at the center of the vehicle body and a main converter and an auxiliary power supply are arranged on both sides of the vehicle body, a window for lighting, an air filter for inhaling outside air, and a louver Cannot be installed, the interior of the vehicle becomes dark, the internal working environment is reduced, the maintainability of the charged part is deteriorated, the positions of the air filter and the louver are restricted, and the above-mentioned intake air amount cannot be secured.

Further, if a central passage and a side passage are provided inside the vehicle, a connecting passage connecting the central passage and the side passage is required, so that the vehicle body length must be extended.
Since this cannot be performed, it is impossible to cope with an increase in the capacity of the internal device, and restrictions on the arrangement of the device increase.

As a solution to the reduction in the area of the air filter by providing the main conversion device and the auxiliary power supply device on both sides of the vehicle body, it is conceivable to provide an air filter on the outer plate side of the main conversion device and the auxiliary power supply. But this method is
This method cannot be adopted because the main converter and the auxiliary power supply cannot be directly maintained and inspected, and a step of removing the air filter is required.

Further, it is conceivable to improve the workability at the time of maintenance and inspection by providing an electric lamp inside the machine room. However, when the power is not supplied to the power supply, the lighting cannot be performed. This method cannot be adopted.

Therefore, an object of the present invention is to reduce the noise emitted to the outside of the vehicle, prevent raindrops and snow from entering the inside, perform maintenance and inspection easily, and reduce the weight of the diesel. Getting an electric locomotive.

The lower side of the control device 1 has the above-described blower room.
A blower duct 23 for cooling air sent from the 17 main blowers 5 via a blower duct 21 is stored under the floor. A large-sized air filter 10 is attached to the outer panels on both sides of the control device room 15, and a lighting window 32 is provided above the air filter 10.

The control unit 1 and the power supply unit 2 house a drawable electrical unit 26 as shown by a broken line in FIG.
As shown by a two-dot chain line, it can be pulled out to the outside of the outer panel.

Next, the operation of the thus constructed diesel electric locomotive, particularly the flow of the cooling air, will be described with reference to FIG. First, the air inside the engine room 16 heated by the engine 3, the main generator 4 and the muffler 11 housed in the left and right engine rooms 16 is taken into the control device room 15 from the air filter 10 and the engine room 16 Partition wall between control equipment room 15
It is ventilated by the outside air sent to the engine room 16 through the 12 ventilation fans 9.

The outside air sent into the engine room 16 flows around the engine 3, the main generator 4, and the muffler 11 to cool them, and the reverse air formed on the upper part of the partition wall 12 between the engine room 16 and the blower room 17. The gas flows into the exhaust duct 20 in the upper part of the blower room 17 from the trapezoidal opening, and is discharged to the outside from the left and right exhaust ports of the exhaust duct 20.

FIG. 7 is an explanatory diagram showing the flow of the cooling air discharged from the control equipment room 15 via the engine room 16 to the exhaust duct 20 of the blower room 17. As shown by the arrow in FIG.
The outside air sucked into the inside from the air filters 10 provided on the outer panels on both sides of the control device room 15 on the left is supplied to the right engine by the ventilation fan 9 provided at the lower center of the partition wall 12 between the engine room 16. Flow into chamber 16.

Then, the outside air is heated by the heat of the surface of the diesel engine 3 and the main generator 4 in the engine room 16, and
7 through the opening provided at the upper right end of the engine room 16 to the exhaust duct at the ceiling of the blower room 17
It flows into 20 and flows out.

On the other hand, with the operation of the main blower 5, the engine room
Outside air flowing into the inside of the intake duct 7 from the air filter 6 provided on the outer plate 16 flows into the blower room 17 through the intake duct 7 of the blower room 17 communicating with the intake duct 7, The air is sucked and supplied from a pair of outlets 21a formed in the lower portion of the blower room 17 to a main generator and a control device room 15 (not shown) suspended below the floor. The air that has flowed into the control device room 15 cools the control device 1 and is discharged to the outside through the exhaust duct 24 shown in FIG.

FIG. 8 shows that the blower duct 17
Through the ventilation duct 23 below the engine room 16
FIG. 9 is an explanatory diagram showing a flow of cooling air for cooling the inside of the box of the control device 1 through 15 ventilation ducts 23.

That is, the outside air flowing into the intake duct 7 from the air filter 6 provided on the outer panel of the engine room 16 is drawn into the main blower 5 of the blower room 17 adjacent to the right side in FIG. The air is sent to a pair of air ducts 21 connected to the lower end of the main fan 5. Then, the cooling air is supplied to the inside of the control device from the air duct 23 at the lower end of the control device room 15 via the air duct at the lower end of the engine room 16 as shown by the arrow.

Therefore, in the diesel electric locomotive thus constructed, the diesel engine 3 and the main generator 4 are divided into the engine room 16 surrounded by the partition wall 12 and the vehicle body outer panel.
The noise radiated outside the vehicle can be suppressed.

That is, the intake duct 7 is provided between the outer plate and the diesel engine 3 and the main generator 4 in the engine room 16.
Because it is partitioned by duct cover 25 etc.
The internal noise is attenuated by the cover 25 and the intake duct 7, and the noise emitted outside the vehicle can be reduced.

The noise transmitted from the ventilation fan 9 provided on the partition wall 12 between the engine room 16 and the control device room 15 to the control device room 15 is far greater than the area of the opening of the ventilation fan 9. Since the noise is attenuated by the large control device room 15, noise emitted from the control device room 15 to the outside can be suppressed.

Accordingly, the suction area of the air filter 10 provided on the outer panel of the control device room 15 can be increased, so that the flow velocity of the outside air passing through the air filter 10 shown in FIGS. 1, 5 and 7 can be reduced. It can prevent rain and snow from entering, and can prevent an increase in maintenance and inspection due to clogging due to these rain and snow.
Pressure loss of the air passing through the
The intake air volume can be increased.

Further, the cooling air flowing into the engine room 16 from the control device room 15 via the ventilation fan 9 was discharged to the outside from the upper opening of the engine room 16 on the side of the blower through the exhaust duct of the blower room 17. In addition to being able to double as an exhaust duct for the exhaust pipe 19, high temperature air in the engine room 16 can be discharged after the operation (after entering the garage and stopping the diesel engine).

Further, since the air filter 6 is provided on the entire outer panel of the engine room 16 having the largest area, the flow velocity of the intake outside air for the blower can be reduced, and clogging or intrusion by rain or snow can be prevented. Not only can the frequency of maintenance and inspection be reduced, but also the outside air that has flowed into the intake duct 7 from the air filter 6 is suddenly changed in the longitudinal direction of the vehicle body by the duct cover 25. There is also an advantage that even if rain or snow enters the inside of the intake duct 7 after passing through the intake duct 7, it can be separated from the intake duct cover 25 by its inertia.

The outside air flowing from the intake duct 7 into the blower room 17 flows into the blower room 17 which has rapidly expanded from the flow path cross section of the intake duct 7, so that the flow velocity rapidly decreases in the blower room 17. In addition, the blower room 17 functions as a snow cutting room, and can prevent raindrops and snow powder sucked into the main blower 5.

Further, since the blower room 17 is provided at the center of the vehicle, and the opening of the outer plate of the blower room 17 is not formed, the noise transmitted to the outside and the cab 14 can be suppressed. In addition, the amount of air blown to each room symmetrically adjacent to both sides of the blower room 17 can be made uniform.

On the other hand, if the size of the intake duct cover 25 of the engine room 16 is made larger than the outer shape of the air filter 6, after the intake duct cover 25 is removed, the air filter 6 can be replaced from the side of the passage in the vehicle. Not only can the parts of the diesel engine 3 and the main generator 4 be taken in and out, but also the assembly, maintenance and inspection work becomes easy.

Also, the engine room 16 shown in FIG.
In the event that the amount of outside air flowing into 17 is insufficient with only the ventilation fan 9, the doors 13 on both sides of the partition wall 12 between the engine room 16 and the blower room 17 are opened, and the suction force of the main blower 5 is opened. In addition, even if the ventilation fan 9 stops, by removing the intake duct cover 25, the engine room 16
Outside air, and can be exhausted from the exhaust duct at the upper part of the engine room 16 through the exhaust duct 20 of the blower room 17, so that the operation of the locomotive continues and the vehicle travels to the next stop station or garage. be able to.

In the above embodiment, the diesel electric locomotive has been described as an example. However, if the electric locomotive has a power source therein, the present invention is similarly applied to an electric locomotive using a gas turbine engine. By doing so, it is possible to prevent noise emitted to the outside of the vehicle, raindrops and snow from entering the cooling air, and improve maintainability.

Further, since the intake duct 7 can be used as both the intake filter 8 for the engine and the intake duct for the main blower 5, the structure can be simplified and the intake filter 8 can be used.
Can also increase the dust removal effect.

Further, as shown in FIG. 5, since the electric component unit 26 can be taken out from the outer plate side, the forklift can be placed beside the vehicle body and directly transferred, and the large This makes maintenance and inspection of the unit with increased weight easier.

Further, since it is not necessary to provide a T-shaped path for connecting the central passage and the side passage unlike the related art, it is possible not only to suppress an increase in the length of the vehicle body, but also to prevent the vehicle from being extended from the rear door of the cab. The driver's cab on the side can be placed inside the vehicle with good visibility with the light from the lighting window 32, so for example, when starting up the power supply of the locomotive, it is necessary to confirm whether the operator is left in the machine room It will be easier.

Further, as shown in FIG.
By making the length of 18 the same as the length of the engine room 16, the engine room
Since it is supported by the rafters 30 at the upper end of the partition walls 12 on both sides of the 16, it can be supported by a high steel structure without adding another reinforcement for mounting the radiator 18, reducing the weight of the vehicle body You can also.

FIG. 9 is a cross-sectional view showing a second embodiment of a diesel electric locomotive according to the present invention, and corresponds to FIG. 1 shown in the first embodiment. The other is the same as FIG. 1 in that the chamber is only on one side. Similarly, FIG. 10 is a cross-sectional view showing a third embodiment of a diesel electric locomotive according to the present invention, and corresponds to FIGS. 1 and 9 and shows a case where a set of an engine or a power supply unit serving as a power source is provided.
