Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current collecting device and a current collecting method for railway vehicles, and more particularly to a current collecting device and a current collecting method suitable for high-speed railway vehicles.

[0002]

2. Description of the Related Art Aerodynamic noise accompanying the speeding up of high-speed railway vehicles increases in proportion to about the eighth power of the speed, and therefore increases rapidly as the vehicle speed increases. On the other hand, interest in environmental protection is expected to increase in the future. For this reason,
For vehicles traveling at high speed (for example, 270 km / h or higher), a low-noise current collector is desired.

Nikkei Mechanical May 4, 1992 Issue
Pages 22 to 40 "Low-noise current collectors" have been proposed for "The Shinkansen that gets faster". This document (especially 27th
Page) states the following.

In order to reduce noise, it is desirable to streamline a member provided with a sliding plate as a current collecting member. Lifting force is generated in consideration of a combination of a streamlined member and a column that supports the streamlined member. As a result, the contact strips separate from the overhead line or the pressing force against the overhead line becomes excessive, and the overhead line is cut. A current collector will be installed exclusively for the up and down routes and will be switched at the return station. The current collector is T-shaped, and each member is enlarged to reduce the generation frequency.

Then, in consideration of these, FIG.
A T-type current collector is shown in FIG. This current collector includes a member that supports the contact plate with a fine movement spring, a lifting cylinder that supports the contact plate through a restoring spring, and an insulator that supports the cylinder.

Incidentally, the conventional pantograph type current collector is
It is composed of a pantograph having a contact plate, an air cylinder for raising and lowering the pantograph, four insulators for insulatingly supporting the mount on which the pantograph and the air cylinder are mounted, and a conductive cable installed on the roof. Air is supplied to the air cylinder by a pipe installed through the insulator.

On the other hand, Japanese Patent Application Laid-Open Nos. 5-49103 and 5-49104 also propose a structure for reducing noise in a current collector for a high-speed railway vehicle.

[0008]

The T-type current collectors proposed in the above documents and the current collectors for high-speed railway vehicles proposed in the above publications all solve the problems associated with high-speed running. It is what However, like the conventional pantograph, the pantograph functions (1) a contact following function to an overhead line and (2) a conductive function to guide collected power to the vehicle side are to be achieved with a single configuration. For this reason, it is difficult to satisfy the high requirements regarding the response of overhead line tracking and the noise reduction that occur with the increase in speed.

For example, the T-type current collector has the following problems. First, the lifting cylinder is on the side of the contact plate with respect to the support insulator. Therefore, the lifting cylinder must be an air cylinder. In a high-speed vehicle, a hydraulic cylinder is desired from the viewpoint of responsiveness to control, but it cannot be used.

The elevating cylinder has a control system for keeping the contact force to the overhead wire constant, and a load cell, for example, is required as a means for detecting the contact force as a control input. This installation position is closer to the slide plate than the lifting cylinder, but this part is a high-voltage part and requires insulation treatment.

Further, although the current collector is provided for collecting current, the content of the conductive system is not disclosed at all.

Further, when switching the current collector at the turnaround station, it is considered that the current is lowered or raised by the lifting cylinder to be used. In this case, since the current collectors that are not used are protruding, it is considered that the contribution to noise reduction is not sufficient.

The current collector disclosed in the above publication may have the same problem.

An object of the present invention is to provide a current collecting apparatus and a current collecting method which are excellent in controllability and response of overhead line tracking and suitable for high-speed railway vehicles.

Another object of the present invention is to provide a current collecting device and a current collecting method which generate less noise and are suitable for high-speed railway vehicles.

Another object of the present invention is to provide a current collecting device and a current collecting method which can prevent the generation of noise from the current collecting device when not in use.

Another object of the present invention is to provide a vehicle provided with a current collector which can always appropriately control the pressing force against an overhead line during high-speed traveling.

[0018]

A feature of the present invention is that the function of the pantograph, that is, the function of following an overhead line and the function of conducting the collected power are differentiated, and a current collector having a configuration corresponding to each function is provided. It is a device. That is, a current collecting member, a drive mechanism that moves the current collecting member, an insulator that connects the current collecting member and the drive mechanism, and electric power collected by the current collecting member that is installed in parallel with the drive mechanism. And a conductor that conducts electricity to the load side. Another feature of the present invention is to mount a current collecting member, a drive mechanism for moving the current collecting member, a conductive mechanism for conducting the electric power collected by the current collecting unit, a driving mechanism and the conductive mechanism. Current collector having a gantry, a rotating means for rotating the gantry, and an accommodating portion provided on the roof of the vehicle for rotating the rotating means to accommodate the drive mechanism and the conductive mechanism. It is in.

[0019]

According to the present invention, the current collecting function part, that is, the current collecting member, the drive mechanism for driving the current collecting member to follow the overhead wire, and the power conducting function part are separately provided, so that the current collecting function part is provided. Can be made lighter and smaller, and the control characteristic of following the overhead line can be improved. In addition, a power collecting function is sufficiently ensured.

Furthermore, since a storage unit is provided on the roof of the vehicle, the drive mechanism is always located inside the storage unit, and when the current collecting function unit is not used, it is stored in the storage unit above the vehicle together with the power conducting function unit. Generation of noise while driving is also suppressed.

First Embodiment A first embodiment of the present invention will be described with reference to FIGS. First, FIG. 1 shows an external view of a high-speed vehicle to which the present invention is applied. The outer surface of the vehicle body 2 is smoothly formed to reduce noise, and the truck is also covered with the cover 2C. The lower half of the current collector 20 is located at a position surrounded by the storage dome 4, and main components such as an insulating support insulator, a conductive cable head, and a current collector are located at a substantially central portion of the storage dome 4 during current collection. It projects and is in contact with overhead line 1. The outer surface of the storage dome 4 has a streamlined shape with little air resistance.
A pedestal 3, a high voltage cable 5, a high voltage connector 6, a cylinder 7 for raising and lowering the current collector, a rod 8 and the like are arranged.

In such a high speed vehicle, an alternating current voltage of 25 kV and 50 Hz to 60 Hz is usually used as the overhead line voltage. In order to secure insulation distance and creepage distance under such high voltage, it is necessary to use an insulator which is very tall and has a large number of folds as the current collector 20. Such an insulator becomes a running resistance at the time of running at a high speed and becomes a large noise source. Therefore, the current collector 20 of the present invention is housed in the storage dome 4 when it is not in the current collecting state.

FIG. 2 shows a state in which the current collecting device 20 is in a current collecting state and stands up substantially at the center of the storage dome 4. The gap between the current collector 20 and the storage dome 4 and the storage opening in the power collecting state are completely closed by the shutter mechanism 9.

A current collector 2 to which the present invention is applied is shown in FIGS.
0 and the details of the storage dome 4 are shown.

Since the current collector 20 does not operate by the folding mechanism like the conventional pantograph, the current collector 22 and the insulating support insulator 3 are rotated by the turning mechanism 40 when the current is not collected.
0, drive rod 31, vertical drive cylinder 32,
The conductive cable heads 50 are rotated together and stored in the storage dome 4. This reduces air resistance while traveling and also reduces noise.

For storing and unfolding, the current collecting device 20 is moved by the hoisting cylinder 7 and the hoisting rod 8 to the shaft 40 of the turning mechanism 40.
It is performed by rotating around A and undulating. The turning mechanism 40 is supported by a fixing member 41 provided on the pedestal 3 on the roof of the vehicle body 2.

When the current collector 20 is undulated, the shutter mechanism 9 is opened by the shutter cylinder 42 and the shutter rod 43 operating, and is stored when the current collector 20 is collecting current and in the storage dome 4. It is closed when it is. These operations are performed under the control of a separately provided sequencer or computer. Details will be described later.

Since the high-voltage flexible cable 44 is moved every time the current collector 20 is stored and started, it is worn out and needs to be replaced regularly. Therefore, the high-voltage connector 6 is provided between the high-voltage cable 5 embedded in the vehicle body 2 and the high-voltage flexible cable 44 to facilitate replacement.

Shutters 110, 120, 130, 14
0 gap, insulator 30, insulator 50 and shutter 130
Water that has entered the storage dome 4 through the space between the storage dome 4 and the storage dome 4 is drained onto the roof through the drain holes 46 provided at the lower portions of both sides of the storage dome 4. As shown in FIG. 5, the roof of the vehicle body 2 has a circular arc shape that is convex upward, so that water can be easily drained from the drain holes 46 at both ends of the storage dome.

As shown in FIGS. 6 to 9, a contact current collecting contact plate 21 as a current collecting member is embedded in the upper part of a delta wing type current collector 22, and a contact plate pressing spring 23 and It is pressed against the overhead wire 1 by a drive system described later. The current collector 22 is fixed to the upper end of an insulating support insulator 30 with a bolt, and the insulating support insulator 30 is fixed to a driving rod 31 protruding from a driving cylinder 32 below the insulating support insulator 30. Reference numeral 33 is a load cell for detecting a reaction force of a force acting between the driving rod 31 and the insulating support insulator 30, that is, a reaction force of pushing up the current collector 22, and 34 is a displacement gauge. As will be described in detail later, the drive rod 31 is pushed up by the fluid pressure generated by the fluid generator provided separately, and the pressing force of the current collecting member 21 against the overhead wire 1 is controlled to an optimum value.

When viewed from above, the current collector 22 has a substantially triangular blade shape as shown in FIG. Both ends in the width direction are bent downward. A friction plate 21a made of a member harder than the blade (for example, iron, copper, or brass) is fixed to the upper surface of this portion. This member is a fixed contact plate 21a, and when the overhead wire 1 is located at the wing tip, the overhead wire 1 causes the current collector 2 to
The current collector 22 is prevented from being worn by directly contacting the second electrode 2.
The scraping plate 21a is fixed to the current collector 22 with bolts so as to have the same potential as the current collecting member 21 to prevent sparks. The bolt is provided in the concave portion of the contact plate 21a to reduce the convex portion on the surface. A spring 2 is provided between the contact plate 21a and the current collector 22.
There is no 3.

The contact plates 21 and 21a are electrically connected to the conductor wire 51. When the current collector 22 is a non-conductive body such as FRP, a conductive body is provided between the contact plates 21 and 21a and the conductive wire 51.

The outer surface of the connecting portion between the insulating support insulator 30 and the current collector 22 is arcuate. This reduces the generation of aerodynamic noise from this part.

As shown in FIG. 6, the longitudinal section of the current collector 22 has a streamlined shape in which the height dimension decreases toward the rear. Moreover, in order to make it lightweight, it is made of Al material. Alternatively, GFRP or CFRP may be mainly used, and the surface thereof may be coated with an aluminum alloy material.

Driving rod 31 of driving cylinder 32
The lower end of the insulating support insulator 30 is connected via a unit of the load cell 33. The insulating support insulator 30 and the drive rod 31 are connected using the upper and lower flanges of the unit of the load cell 33. The lower end portion of the insulating support insulator 30 is a column, and its diameter is the same as the outer diameter of the cylinder portion of the cylinder 32. This part is the sleeve 59
Covered with. The sleeve 59 has a half-split shape, and is fixed to the columnar portion of the insulating support insulator 30 and the cylinder portion of the cylinder 32 from outside in the radial direction with flat head screws. Sleeve 5
The length of 9 is longer than the stroke of the driving rod 31.
The corners at the upper end of the sleeve 59 are rounded. The drive rod 31 is a hydraulically driven rod. 130 is
The shutter covers the periphery of the sleeve 59 and will be described in detail later.

The conductive cable head 50 includes the insulator 5
The conductor 53 penetrates through the central portion of the second axial direction. The upper end of the conductor 53 projects from the insulator part,
A bracket that protrudes to the side is attached with a bolt. A protective cap may be attached to this portion as is known. A high voltage flexible cable 44 is attached to the lower end of the conductor 53. The outer diameter of the conductive cable head 50 is gradually reduced toward the upper end, and constitutes an insulator for high voltage.

The upper end of the conductor 53 and the collector 22 are connected by a flexible braided conductor wire 51. Conductor 5
1 is fixed with bolts and nuts. The conductor wire 51 is composed of a braided conductor wire so that the current collector 22 can easily move up and down with respect to the conductive cable head 50.
At least a part is folded back to form a U shape. In this way, by making a part of the conductor wire U-shaped, it is possible to easily move up and down even if the distance between the fixed ends at both ends of the conducting wire 51 is small. In the traveling direction of the vehicle, the conductive cable head 50 is on the back side of the insulating support insulator 30, and the conducting wire 51 and the current collector 2 are provided.
2. The coupling position with the conductor 53 is also located on the back surface of the insulating support insulator 30.

As shown in FIGS. 10 to 12, the insulator of the conductive cable head 50 has irregularities, and the columnar insulator 52 is installed in the lower portion 52 thereof. The lower end of the insulator 52 is attached to the attachment seat 55 from above with bolts. The cylinder portion of the cylinder 32 is formed integrally with the mounting seat 55. The side surface (the rear side in the traveling direction) of the mounting seat 55 has an opening (55a), and the connecting portion of the high-voltage flexible cable 44 can be laterally inserted into the lower end portion of the insulator 52. Lower end of conductive cable head 50, mounting seat 5
Each of the upper ends of 5 has a flange, which is connected with a plurality of bolts.

Connection portions with the undulating cylinder 7 are provided on both sides of the space of the mounting seat 55 through which the connection portion between the conductive cable head 50 and the high-voltage flexible cable 44 penetrates. The up-and-down cylinder 7 extends and contracts in the longitudinal direction of the vehicle. The high-voltage flexible cable 44 is located between the two hoisting cylinders 7, 7. The high voltage flexible cable 44 is coupled to the cable 5 via the connector 6. The high voltage flexible cable 44 is softer than the cable 5. The connector 6 is constructed so that it can be relatively easily connected to and detached from the high voltage flexible cable 44.

Returning to FIGS. 6 to 7, the driving cylinder 3
2, devices such as the connector 6 and the undulating cylinder 7 are installed on the pedestal 3 via the mounting seat 41. The pedestal 3 is bolted to a pedestal formed on the roof of the vehicle. The pedestal 3 below the high-voltage flexible cable 44 is notched, and the bending space of the high-voltage flexible cable 44 is enlarged to facilitate the bending of the flexible cable due to the rotation of the insulating support insulator 30.

According to this structure, the driving rod 3
When 1 is operated, the high voltage flexible cable 44 is not affected.
The drive rod 31 presses the contact plate 21 against the overhead wire 1 with a predetermined contact force, and moves up and down at a considerable frequency. The high-voltage flexible cable 44 is bent by the operation of the hoisting cylinder 7, but the state is substantially during the folding operation, and the frequency is extremely low. Therefore, it is possible to extend the service life of the cable 44. Further, the load cell 33 can detect only the contact force with the overhead wire.

Since the insulating support insulator 30 is arranged between the driving rod 31 and the sliding plate 21, the driving rod 3
No high voltage is applied to 1. Therefore, the drive cylinder 32 can be hydraulic, and the response of the drive force to the control signal can be improved.

Similarly, since the load cell 33 (pressure sensor) and the displacement gauge 34 can be arranged at a position where high voltage is not applied, an accurate control input signal can be obtained.

A sleeve 59 is attached to the lower end of the insulating support insulator 30.
Since the insulating support insulator 30 has a small-diameter rod 31 at the lower end, the gap between the insulating support insulator 30 and the storage dome 4 can be reduced, and rain, snow, and air can be prevented from flowing in. Therefore, the length of the insulating support insulator 30 from the lower end of the fold can be reduced.

If the length of the cylinder at the lower end of the insulating support insulator 30 is made longer than the stroke of the drive rod 31, the sleeve can be eliminated.

As shown in FIGS. 13 to 14, the current collector 20
Shutters 110, 120, 130, and
140 is provided and normally the opening is closed. Shutter 110
Is a shutter that covers the opening through which the current collector 22 passes, and has a single plate shape. The shutters 120, 120 are shutters that cover an opening through which the insulating support insulator 30 passes, and are divided into two in the vehicle width direction, and one opening is closed by a pair of rotary shutters. The shutters 130, 130 are slide type shutters that cover the opening when the sleeve 59 and the insulator 52 are upright, and are divided into two in the vehicle width direction, and one opening is closed by a pair of shutters. When the openings of the shutters 130, 130 are closed, two circular holes through which the sleeve 59 and the insulator 52 penetrate are opened. When the shutter 140 stores the current collector in the storage dome 4,
A single shutter is a sliding shutter that closes the opening of the shutters 130 and 130. At this time, the shutters 130 and 130 do not close the openings.

Next, the structure of the drive mechanism of the shutter 110 will be described with reference to FIGS. As shown in FIG.
The shutter 110 is a slide type and slides along the longitudinal direction of the vehicle. Aperture 1 for closing the shutter 110
Guide rails 115 that support both ends of the shutter 110 are provided at both ends of the vehicle 10a in the width direction of the vehicle. Shutter 1
Both ends of 10 are supported by guide rails 115 via four rollers 112. The guide rail 115 guides the upper, lower, and side surfaces of the roller 112. The shutter 110 is located on the back surface of the storage dome 4 when it is opened, and enters the opening when it is closed. That is, the upper surface of the shutter 110 when closed is substantially flush with the upper surface of the storage dome 4. The guide rail 115 is curved so as to move the shutter 110 as described above. The vertical movement cylinder 42 is attached to the pedestal 3.

As shown in FIG. 16, the shutter 120 opens and closes around the hinge 122. The cylinder 129 is attached to the base 3.

The shutter 130 is a slide type like the shutter 110. Guide rail 13 of shutter 130
No 5 is on the side of the opening. This is to prevent intersection with the shutter 140. Therefore, there is no guide roller in the shutter portion that closes the opening. In order to mount the guide roller, the shutter 130 has a shape that largely projects to the rear side in the moving direction when opened. The cylinder 139 is attached to the base 3. Other configurations are the same as the configurations of the shutter 110.

In FIGS. 15 and 16, the shutter 11
The heaters 47, 48 are installed in the storage dome 4 around 0, 120.
Set up. A heater is also installed at the connection between the shutters 120 if necessary. Other shutters 130, 140
Similarly, a heater (not shown) is installed. In the case of freezing in the winter, by energizing this heater to melt the ice and then opening and closing the shutters 110, 120, 130, 140, the current collector 20 can be easily undulated.

The shutter 140 is of a slide type like the shutter 110. Guide rail 14 of shutter 140
No 5 is on the side of the opening. This is to prevent intersection with the shutter 130. Therefore, there is no guide roller in the shutter portion that closes the opening. In order to mount the guide roller, the shutter 140 is formed so as to largely project to the rear side in the moving direction when opened. Cylinder 149
Is attached to the base 3. The other structure is the shutter 11.
It is similar to the configuration of 0.

As shown in FIG. 17, the storage dome 4 has four
It is divided into three parts A, 4B, and 4C. Storage dome 4
A is a range from the guide rail 135 of the shutter 130 to the guide rail 115 of the shutter 110. Inspection lids 4Aa, 4Bb, 4C are appropriately provided on the side surface of the storage dome 4.
c is provided to inspect and assemble the equipment inside the storage dome 4.
Replace parts.

Current collector 2 protruding above the storage dome 4
As shown in FIGS. 18 to 20, 0 is stored in the storage dome 4 by driving the undulating cylinder 7. First, Fig. 1
As shown in 8, lower the current collector 22 a little (about 100 m
m) Move away from overhead lines. Next, as shown in FIG. 19, the shutter 9 is opened, the current collector 20 is tilted to be housed in the storage dome 4, and finally the shutter 9 is closed.

The state where the current collector 20 is stored in the storage dome 4 is as shown in FIG. 15, all the openings are closed by the shutter device 9, and the outer surface of the storage dome 4 has a smooth streamline shape. Therefore, it is less likely to become a running resistance or a noise source during high speed running.

An example of specific dimensions of the embodiment to which the present invention is applied is as follows.

Height of the storage dome HD = 700mm Total length of the storage dome L = 9300mm (See above Figure 4) Width of the bottom side of the storage dome WDL = 2500mm Width of the top side of the storage dome WDH = 1800mm (see above Figure 5) For insulation Height of support insulator HG = 600mm Height of conductive cable head HC = 430mm Height of front part of current collector TA = 130mm Front / rear length of current collector LA = 600mm Distance between tip of conductive cable head and overhead wire TB = 290 mm (see FIG. 7 above) If the movable stroke of the drive cylinder is set to about 300 mm, a sufficient space for installing the drive cylinder 32, the connector 6, the undulating cylinder 7, etc. in the storage dome 4 can be secured.

Next, the assembling procedure will be described. The current collector 22, a current collector 20 including a driving cylinder 32 having an insulating support insulator 30 attached thereto, an undulating cylinder 7, a high-voltage flexible cable 44, and a connector 6 are installed on the pedestal 3. The current collector 20 is stored in the storage dome 4 (FIG. 14). At this time, the drive cylinder 32 is in the most contracted state. The tip of the current collector 22 is placed on a buffer seat (not shown) installed on the surface of the pedestal 3. Also, the pedestal 3 has cylinders 42, 129, 129, 139, 1
Install 39,149.

In this state, the pedestal 3 is placed on the roof of the vehicle 2.
Bolt to the roof. In this state, the current collector may be stored. In this state, the cylinder 42,
You may attach 129,129,139,139,149.

Next, the connector 6 and the cable 5 are connected. In addition, each cylinder 7, 32, 42, 129, 12
A driving fluid pipe is connected to 9, 139, 139, and 149. Others Connect the sensor.

Next, the storage dome 4A is placed and fixed to the roof with bolts. The shutter 11 has already been installed on the storage dome 4A.
0, 120, 120, 130, 130, 140 are attached. From the opening of the inspection lid, cylinders 42, 129,
129, 139, 139, 149 and shutters 110, 1
20, 120, 130, 130, 140 are connected.
Next, the storage dome 4B, 4C at the end is placed, and the roof 2,
It is fixed to the storage dome 4B. The connecting parts of the domes overlap each other.

The replacement of the high-voltage flexible cable 44 and the conductive cable head 50 is carried out by removing the storage dome 4 with the current collector 20 housed in the dome. Opening 5 of mounting seat 55
Since 5a faces upward and the connector 6 is provided, the replacement can be performed relatively easily. Cylinder 42,1
39, 139, 149 can be attached to the storage dome 4B in a substantially horizontal direction. According to this, the storage dome 4 can be made one. Also, the inspection lid can be made smaller. It is easy to connect the cylinders 42, 139, 139 and 149 to the shutter and the storage dome 4. This assembly is performed by reversing the up-down direction of the storage dome 4.

Storage dome 4 with sleeve 59 penetrating therethrough
Similarly, the shutters 130, 130 are also raised upward in an arc shape. The shutter 130 has two semi-circular openings, and two holes are formed by closing the two shutters 130, 130. These two holes are holes through which the sleeve 59 and the insulator 52 pass. A cushioning rubber is attached around the hole. The hole on the sleeve 59 side is slightly larger because the sleeve 59 moves up and down.

In FIG. 21, the insulating support insulator 30 (30a, 30a,
30b, 30c) and a horizontal cross-sectional view of the conductive cable head 50 and the relationship between the air flow.

(A) is a circular insulating support insulator 3 having an outer diameter.
The outer diameter of 0a is slightly larger than that of the round conductive cable head 50 (substantially the same diameter in terms of aerodynamics), and it is arranged in combination before and after the flow. The flow of air mainly hits the insulating support insulator 30 on the traveling direction side, but the wind that also goes around the conductive cable head 50 may hit the wind and generate a certain amount of noise.

(B) shows the outer diameter d of the insulating support insulator 30b.
1 is sufficiently larger than the outer diameter D1 of the conductive cable head 50. Most of the air flow hits the large-diameter insulating support insulator 30 located on the upstream side, and does not hit the conductive cable head 50. Therefore, noise is reduced as a whole.

D1> D1 d1 and hatching part: trough of folds of supporting insulator D1 outer diameter: ridge of fold of cable head insulator (c) is a width of insulating supporting insulator 30c in a direction perpendicular to the flow of air. It is formed into a wider, more streamlined shape, and the conductive cable head 50 is positively hidden in the shadow. By doing so, noise is further reduced as compared with the example of (b). As described above, it is desirable to make the outer diameter or width of the insulating support insulator 30 larger than the outer diameter of the conductive cable head 50. Insulating support insulator 30
Is made of epoxy resin.

The distance L of the space between the two insulators is determined from the viewpoint of reducing noise. It is also possible that both noises interfere with each other to reduce noise. The diameter of the insulating support insulator 30 is the same from the upper end to the lower end (above the storage dome 4), but may be increased downward, for example. in this case,
Since the wind flow is different in the vertical direction, noise reduction can be expected.

Further, as shown in FIG. 22, the insulating support insulator 30 has a center of gravity G of the current collector 22, that is, a position where the weight of the current collector 22 acts and a lift force which the current collector 22 receives by the flow of air. It is desirable to place it just below the position where is operated. Lifting force acts on the current collector 22 when the vehicle is traveling. When the vertical cross-sectional shape of the current collector 22 is vertically symmetrical, since the insulating support insulator 30 is installed, the flow velocity of air on the lower surface of the current collector 22 is lower than that of the upper surface. For this reason,
The lift force acting on the current collector 22 acts upward. If the acting position of the lift acting on the current collector 22 is the position of the center of gravity G and the insulating support insulator 30 is installed corresponding to this position, the rotational moment ML shown in the figure acts. Never. Therefore, the current collector 22
Also, it is possible to prevent unreasonable force from acting on the insulating support insulator 30.

It is desirable that the center of gravity G of the current collector 22 and the acting position of the lift of the current collector 22 are coincident with each other as described above. However, when it is not possible to match the position of the center of gravity with the position where the lift acts on the structure of the current collector, it is necessary to consider the position as close as possible.

It is expected that the storage dome 4 will cause an upward angle in the air flow. To counter this, tilt the current collector 22 according to the angle of the air flow, or
Alternatively, it is conceivable to move the current collector 22 to a position that is not affected by the angle of the air flow generated by the storage dome 4. In addition,
The angle and movement of the current collector 22 are preferably adjusted according to the traveling speed.

FIG. 23 shows a state in which the present invention is applied to a train set.

In this figure, the vehicle 2 (2A to 2H) shows a state where it is proceeding from right to left as indicated by the arrow. Normally, the air resistance is lowered, and the noise is reduced by disposing the current collector 20 at the position where the boundary layer is developed.
It is common to collect electricity with a vehicle behind the train. Therefore, also in this figure, the rear two current collectors (20F, 20H) are set up and the front two current collectors (20A, 20C) are housed in the storage dome 4.

The electricity collected by the current collector 20 is guided to the high-voltage equipment box 60 through the high-voltage connector 6 and the high-voltage cable 5. In the high-voltage equipment box 60, a power-receiving vacuum circuit breaker (VCB) 61 and a vehicle-use VCB 62 are arranged, which are connected to each other through a conductive cable head 68 and a high-voltage pull-through wire 67. The VCB 61 for receiving power is the current collector 2
This is to prevent a high voltage from another current collector from being applied through the high-voltage pull-through line 67 when 0 is not used and is stored.

The vehicle-use VCB 62 turns on / off the power supply path to the current collector 20 provided in each vehicle 2. The current thus passing through the vehicle-use VCB 62 is dropped by the main transformer 63, and then the main converter 6
4 converts and controls into a three-phase AC of a frequency and a voltage according to the speed and driving force of the vehicle to drive the main electric motor 65. The current on the negative side of the primary circuit of the main transformer 63 returns to the rail 69 through the wheel axle 66. The high-voltage switch 61 disconnects high voltage from another current collector when the current collector 20 is stored.

FIG. 24 shows an example of equipment arrangement in the high-voltage equipment box 60. This figure is an overhead view of the high-voltage equipment box.
Two VCBs 61, 62 and four conductive cable heads 68 are installed in one box 60. The inside of the high-voltage equipment box 60 is at atmospheric pressure, and air that has been waterproofed and dust-proofed by the breather can enter and exit. VCB for power reception
61 and the vehicle VCB 62 are installed in front of and behind the box 60 with a space therebetween. The VCBs 61 and 62 are publicly known, and the electric paths are opened and closed by energizing the electromagnetic coils 61a and 62a. VCB 61, 62, four conductive cable heads 6
Reference numeral 8 is an electric wire 68a connected as shown in the figure. 68aa
Is a cable for connecting to the high-voltage flexible cable 44, 68ab
Is a cable for connecting to the main transformer 63, 68ac, 68a
d is a cable connected to another device box. 68A is an arrester, which is connected to the VCB 62. VCB6
1, 62 have the same specifications. Since the VCB 61 is installed under the floor, the center of gravity of the vehicle can be lowered as compared with the case where the VCB 61 is installed on the roof. Also, since two VCBs 61 and 62 are installed in one equipment box 60,
It can be cheaper than placing it separately.

As shown in FIG. 25, a control device 84 having the following structure is installed in each of the trains of one train. Four current collectors 20A, 20B, 20C, 2
Since there are 0F and 20H, this control device 84
61, drive cylinder 32, undulating cylinder 7, cylinders 42, 129, 129, 139, 139, 14
9 sets are one set, and these four sets are controlled.

There are two sets of input switches SW, which are installed on the cabs at both ends of the rolling stock. One set of switches SW includes a switch 9D1 for instructing which one of the formation cars is the leading car, a switch 9D2 for raising all the current collectors, and a switch 9D3 for storing all the current collectors in the storage dome 4. Become. The controller 84 has a memory 84
A, a CPU 84B, and an input / output interface 84C are included.

The CPU 84B executes the program stored in the memory 84A and performs various processes. When the switch 9D1 which indicates which is the leading car is turned on,
As shown in FIG. 26, the CPU 84B outputs a descending command to the two current collectors 20A and 20C on the leading side (262),
A standing command is given to the two current collectors 20F and 20H on the rear side (264).

The operation procedure according to the down command is as shown in FIG. In the state of FIG. 4, turn off the VCB 61
(271) to prevent sparks. Next, the driving rod 31 is lowered to the lowermost position and brought into the state of FIG. 18 (2
72). Also, the cylinders 42, 129, 129, 13
Shutters 110, 120, 12
0, 130 and 130 are opened (273). Next, using the undulating cylinder 7, the current collector is housed in the housing dome 4 as shown in FIG. 19 (274). Next, the shutters 110, 120, 120 and 130 are closed using the cylinders 42, 129, 129 and 149 (27
5). Since the shutters 120 and 120 overlap, a difference is provided in the operation timing of the cylinders 129 and 129.

Current collector 2 by shrinking drive rod 31 in advance
Since 0 is rotated after being separated from overhead line 1, it can be rotated with a small amount of power. Further, by contracting the current collector 20, the length of the shutters 120, 120 can be reduced and the length of the storage dome 4 can be shortened.

In the stored state, the two openings of the shutter 130 (the sleeve 59 and the hole through which the insulator 52 penetrates) are closed by the shutter 140, so that noise reduction during traveling can be expected. In addition, the invasion of rain and snow can be reduced.

When the standing command of the current collector 20 is given in step 264 of FIG. 26, the shutters 110, 120, 120, 140 are opened (28) as shown in FIG.
1) Next, the current collector 20 is erected (282), and then the shutters 110, 120, 120, 130, 130.
Is closed (283). Next, the current collector 22 is raised by the driving rod 31 to contact the overhead wire 1 (284), and finally the VCB 61 is turned on (285). The effect is similar to the above.

Further, the insulator 30 is provided by the driving rod 31.
Instead of directly moving up and down, insulator 30 and cylinder 32
A link mechanism may be provided between and. According to this, the driving cylinder 32 and the undulating cylinder 7 can be shared.

29 to 31 show the structure of a current collecting drive device 230 for controlling the pushing force of the current collecting device 20. A control load cell 33 and a displacement meter 34 are incorporated between the insulating support insulator 30 and the driving rod 31. The outputs of the control load cell 33 and the displacement meter 34 are fetched and further input to the control device 83 together with the output information of the speed information detector 85 and the route information detector 86, and the optimum lifting force of the overhead line is generated in the control device 83. Is calculated and an electric signal is sent to the servo control circuit 240. The servo valve 243 uses the electric signal to supply the hydraulic power source 2
The hydraulic flow rate from 41 is controlled to control the pushing force u between the drive cylinder 32 and the drive rod 31.

Amplified fluctuating force signal f
The x and the vertical displacement y ₃ are input to the contact force observer unit 233. The control signal r to the servo control circuit 240 is also input to the contact force observer unit 233 at the same time, and then the contact force estimation signal f ^ and the disturbance suppression pressure estimation signal fa ^ are estimated and output.
The contact force observer unit 233 includes a state quantity estimation unit 236, a disturbance suppression pressure gain unit 237, and a contact force estimation unit 238.

Although not shown, a control on the vehicle is also provided.
A target value command unit 231 that optimally and variably sets the contact force target value f * based on a combination of a traveling position information signal and a traveling speed detection signal based on traveling information (speed information 85, route information 86) from the vehicle. , The contact force target value f * set by the target value command unit 231, the contact force estimation signal f ^ estimated and output by the contact force observer unit 233, and the disturbance suppression pressure estimation signal fa.
The difference between the control signal r and the control signal r [= k2 (f * -f

Here, k ₂ is a steady compensation gain of the steady deviation compensating unit 232. The control load cell 33 is attached between the insulating support insulator 30 and the driving rod 31, detects with high accuracy even if a tensile load and a compressive load act, and outputs a fluctuating force signal fx that acts.

Similarly, the displacement gauge 34 is the driving cylinder 3
2 is attached between the driving rod 31 and the driving rod 31, and outputs vertical displacement, speed, acceleration, etc. of the driving rod 31. In addition, the lift is mainly the current collector 22, the insulating support insulator 30.
And the like, and is composed of the total lift fq of the average lift and the variable lift acting vertically. Therefore, by traveling at high speed,
Since the fq applied to the entire current collector 20 becomes large and the contact force f fluctuates greatly with it, the pushing force U is applied to reduce it.

The contact force is represented by the formula (Equation 1). f = fx−m ₁ y _{1 ″ ″} −m ₃ y _{3 ″} −fq (Equation 1) where y ₁ , y ₁ ′ and y _{1 ″} are current collectors The displacement, speed, and acceleration of the contact plate 21 and the like. y ₃ , y ₃ ′ and y _{3 ″} are displacements, velocities and accelerations of the current collector 22, the insulating support insulator 30 and the like.

The specific constants used in this example are as follows. m ₁ = 6,6 kg, m ₃ = 8.5 kg, k ₁ = 4000 N / m, c ₁ = 180 N ^s / m, k ₃ = 590 N / m, c ₃ = 30 N ^s / m, a = 0.3, b = 208 The target value command unit 231 optimally changes the contact force target value f * according to the travel information (travel speed, travel route position, weather, travel time, earthquake, etc.) sent from the onboard controller. It is set. The steady-state deviation compensator 232 uses the target value commander 23
A signal Q obtained by subtracting the contact force estimation signal f ^ from f * set in 1 is multiplied by the steady-state compensation gain k ₂
[= K ₂ (f * −f ^)] is output. And that Q
From the disturbance suppression pressure estimation signal fa ^ is input to the servo control circuit 240. As a result, the driving rod 31 is operated so as to suppress the lift force fq and the external force from the overhead wire 1.

The disturbance suppression pressure gain section 237 calculates the disturbance suppression pressure estimation signal fa ^ by the output signal P of the state quantity estimation section 236 including the lift force fq and the external force from the overhead line 1.

Here, k ₁ is the spring constant of the contact plate pressing spring 23, c ₁ is the damping coefficient of the contact plate pressing spring 23, and k _{1 ″} is the contact force gain.

The calculation of the signal P will be described below. The state quantity estimating unit 238 detects the output signals detected by the control load cell 33 and the displacement meter 34, and detects the detection signal check circuit 2
After it is determined in 53 whether or not it is normal, the fluctuating force signal fx and the vertical displacement y ₃ are input and the servo control circuit 240

Therefore, the eight characteristic roots of the current collector 20 system are (−0.128, ± j12.34), (−1.21) on the complex number plane.

Next, a method for active control using the contact force observer will be described. First, the equation of state of the current collector 20 including disturbances such as external force and lift of the overhead line 1 is expressed as follows.

D / dt (X) = A × X + B × U + D × W (Equation 5) f = C × X + E × W (Equation 6) where X is the state quantity (y ₁ , y ₃ , y ₁ ′, y ₃ ′, z, z

A × 8 matrix, B is an 8 × 1 vector, C is a 1 × 8 vector, D is an 8 × 1 vector, and E is a 1 × 8 vector.

The state equation of the steady deviation compensating unit 232 is expressed as follows. d / dt (Q) = F × Q + G (f * −f ^) From this, Q = k ₂ (f * −f ^) ) Can be expressed as

Here, k ₂ is the steady state compensation gain, Q is the output state quantity (1 × 1) vector of the steady state deviation compensator 232, and F
Is a scalar constant, G is a vector constant, and (f * -f ^) is an input scalar of the force deviation amount control signal.

[0103] U = H × r = H × (Q-fa ^) = H × (Q-k 1 '× P) = K 1 × P + K 2 × Q ············· (Equation 8) Here, K ₁ and K ₂ are vector constants, and K ₁ = −H ×
There is a relationship of k ₁ ′ and K ₂ = H.

From the equations (Equation 5) to (Equation 8), the contact force target value f *, the overall state equation based on the contact force f, and the pushing force U are
When the estimated state quantity P matches the state quantity X, it is expressed as follows.

[0105]

[Equation 9]

[0106]

[Equation 10]

From equations (7) to (10), disturbances are calculated from fa ^ and f ^ obtained by inputting the control signal r of the fluctuating force signal fx and the pushing force U to the contact force observer unit 233. The contact force f can be reduced by inputting the control signal r (equation (Equation 8)) of the pushing-up force U to be suppressed to the servo control circuit 240. It is necessary to appropriately select the disturbance compensation gain k ₁ ′, the vector constant H, and the steady compensation vector F / G used at this time.

In FIG. 31, the control signal r is input and the pushing force u
The structure of the current collection drive mechanism 244 which outputs is shown. This mechanism 2
Reference numeral 44 designates an amplifier color that amplifies the control signal r and a hydraulic pressure source 2
A servo valve 243 for force-controlling the hydraulic pressure from 41 and a servo valve 243.
It is composed of a drive cylinder-32 and a drive rod 31 for exerting an expansion / contraction action by the bo valve 243 to generate a pushing force u.

Although the hydraulic power source 241 is provided here,
If the responsiveness of the servo valve is high, an air source for post-operation may be used. In that case, the transfer characteristics of the push-up force u to the control signal r need to be similar.

FIG. 32 shows two storage mechanisms for storing the current collector 22 in the storage dome 4 by expanding and contracting the two undulating rods 8a and 8b and rotating the same through the rotating mechanism 40. 3 shows an operational block diagram of 360a, 360b. The two storage mechanisms 360a and 360b are the amplifier circuit 3
61a, 361b, switching valves 362a, 362b, and undulating cylinders 7a, 7b. By inputting the operation signal of the undulating controller 364 installed in the storage dome 4, it is operated by the hydraulic pressure from the hydraulic pressure source 363, and the undulating rods 8a and 8b are contracted to show the insulating support insulator 30. It is raised as shown in 18 so that power can be collected from the overhead line 1. Also, when storing, the undulating rod 8a,
As shown in FIG. 19, the undulating rods 8a and 8b are projected from the 8b, and the sliding plate 21 is separated from the overhead wire 1 and stored in the storage dome 4.

As another embodiment of the present invention, the current collector 20 may be driven by an electric motor instead of hydraulic pressure.

Further, the shutter mechanism of the storage dome 4 is unnecessary in a vehicle whose traveling speed is relatively low. That is, since the storage dome 4 itself has a considerable noise reduction effect, the opening for taking in and out the current collector 20 may always be left open.

[0113]

Second Embodiment FIG. 33 shows another embodiment of the present invention in which a conductive high-voltage flexible cable 44 is held in a hollow portion of an insulating support insulator 30. A conductor 53 is provided in an insulator that supports the current collector 22. That is, the current collector 22 is supported by the conductive cable head. The high-voltage flexible cable 44 is taken out from the side of the insulator. The current collector 22 is fixed by screws and nuts provided on the upper end of the conductor of the conductive cable head. According to this, there is an advantage that only one insulator can be provided.

However, since the high-voltage flexible cable 44 moves up and down in accordance with the operation of the driving rod 21, the life of the high-voltage flexible cable 44 is not preferable.

[0115]

[Embodiment 3] FIG. 34 shows the construction of another embodiment of the present invention when applied to a power supply mechanism of the third rail system.

In the present embodiment, the case where the present invention is applied to a vehicle of a system in which current is not collected from an overhead wire arranged above the vehicle but is collected from a third rail 76 provided on the side of the line is shown.

This method is widely used for subway vehicles and the like, and a positive voltage is applied to the rail 75 on which the vehicle travels by applying a positive voltage to the third rail 76 provided on the side of the track to reduce the tunnel cross-sectional area. Feed a negative voltage. The third rail 76 is insulated by the insulator 77. Current collection is performed by pressing the current collecting shoe 73 against the third rail 76.

An insulator 72 for insulating the vehicle is provided on the vehicle side of the current collecting shoe 73, and a control hydraulic cylinder 71 for controlling the pressing force of the current collecting shoe is provided near the vehicle. ing. The control hydraulic cylinder 71 is fixed to the shaft box body or the bogie frame 70 with a small relative displacement with respect to the rail 75, and the electricity collected by the current collecting shoe 73 is transmitted to the conductive cable head 78 via the flexible conductor 74. It is guided to the control device loaded on the vehicle body 2.

[0119]

Fourth Embodiment Another embodiment of the present invention is shown in FIGS. This example is an embodiment in which the current collector 20 is rotated rearward in the traveling direction. The cylinder 7 and the connector 6 are on the front side in the traveling direction indicated by the arrow. High-voltage flexible high-voltage flexible cable 44 is located between two hinges that support current collector 20. The positions of the shutters A, B, C and D are also opposite to those in the above embodiment in the traveling direction.

According to this, as shown in FIG. 38, when the current collector 20 is stored in the storage dome 4, the apex side of the triangle of the current collector 22 is upward. Therefore, the storage dome 4
The shape can be made smaller than that of the above-mentioned embodiment, and the running resistance can be made smaller.

[0121]

[Embodiment 5] In the above-mentioned embodiment, the insulating support insulator 30 is kept upright during traveling, but the hoisting cylinder 7 is operated according to the traveling speed to change the inclination angle and control the lift force. It is possible. In this case, the contact plate 21 and the current collector 22 may be arcuate. When the influence of the wind from the storage dome 4 is large, the current collector 20
It is conceivable to move the vehicle in the traveling direction.

Since the lift force acting on the current collector 22 is increased during high-speed traveling, the undulating cylinder 7 is operated so that the tip of the current collector 22 is slightly downward. In FIG. 32, the undulation controller 364 operates the undulation cylinder 7 so that the tip of the current collector 22 is slightly downward when the speed is higher than a predetermined speed, based on the traveling speed information from the onboard controller. Alternatively, the instruction from the central command room is used.

Further, since the lift becomes large even when passing by an adjacent vehicle in one tunnel, the lift is likewise downward. Turn downward when entering a tunnel at high speed. In FIG. 32, the undulation controller 364 indicates the undulation cylinder 7 based on the traveling position information from the on-board controller.
To operate. Alternatively, the command is issued from the central command room.

[0124]

Sixth Embodiment Further, in order to rectify the rear side of the conductive cable head 50, it is conceivable to provide a rectifying plate on the back surface of the conductive cable head 50. The current plate is an insulator and is attached to the attachment seat 55 of the conductive cable head 50.

[0125]

[Embodiment 7] The current collector 20 has an emergency ground switch EGS.
Is desirable. That is, as shown in FIG. 39, the emergency ground switch EGS300 is arranged in parallel with the conductive cable head 50 of the current collector 20. This emergency ground switch EGS is a rod 3 made of copper driven by a cylinder mechanism 302 operated by an air source 301.
It has 03. The copper rod 303 is always in the storage dome 4, and is protruded to the outside of the storage dome 4 as shown in the figure by an emergency operation of a driver, and its upper end is connected to the current collector 22 via the clip 304. . 305 is
It is a braided copper wire connected to the pedestal 3. The emergency ground switch EGS is for grounding and shorting as close to the current collector 22 as possible in an emergency. The emergency ground switch EGS is
The cylinder mechanism 302 is integrated with the cylinder 32, and is swung up and down together with the insulating support insulator 30 and the conductive cable head 50 by the turning mechanism 40.

According to the embodiment of the present invention described above, the current collecting function part, that is, the current collecting member, the driving function part for driving the current collecting member to follow the overhead wire, and the power conducting function part are configured separately. Therefore, the power collecting function portion is light and small, and it is possible to improve the control characteristic of following the overhead line during high-speed traveling. In addition, the function of collecting electric power is completely ensured.

Further, a streamlined storage dome is provided on the upper part of the vehicle, and the drive mechanism is always positioned inside the dome.
Since the current collecting function part is housed when it is not collecting current, it is possible to suppress the generation of noise.

[0128]

[Embodiment 8] As another embodiment of the present invention, the high voltage cable may be considered to be easy to move by arranging the conductive cable head at an angle. By doing so, the distance between the insulating support insulator and the conductive cable head is not parallel, so the standing waves generated during this interval are reduced and noise is reduced.

[0129]

Ninth Embodiment Another embodiment of the present invention will be described with reference to FIGS. FIG. 40 shows a perspective view of an embodiment of the present invention. The current collector is a current collecting strip 21 for taking out electricity from the overhead wire 1, and a current collector 2 for attaching the current collecting strip 21 in which the left and right front end portions in the front in the traveling direction recede in the width direction.
2, a streamlined support column 400 for supporting the current collector 22, an insulator 500 for electrically insulating the vehicle body 2 from the current collector, and a drive means for driving these up and down (FIG. (Not shown).

Since the contact plate, the current collector, and the like constituting the conventional current collector are composed of two-dimensional members such as a cylinder and a prism, a two-dimensional vortex represented by Karman vortex is generated. It is easy to cause, a large aerodynamic noise is generated, and the air resistance is large, which is a problem in running at high speed. The streamline current collector devised to solve this problem suppresses the generation of Karman vortices compared to the current collector,
Noise is reduced. However, even in this case, since the current collector has a long member in the direction perpendicular to the traveling direction, the flow tends to be two-dimensional. Therefore, even if the current collector was streamlined, the amount of aerodynamic noise generated was large.

The streamline current collector has less noise than the non-streamline current collector, but a low-noise current collector is desired for high-speed traveling with low noise.

In the current collector 22 of the current collector according to the present invention, since the front end portion in the forward direction is retracted in the longitudinal direction,
A vertical vortex is generated around it. This vertical vortex suppresses the generation of a vortex having a two-dimensional structure represented by the Karman vortex found in the conventional current collector. 41 and 42 schematically show the flow around the current collector 22, and show a current collector 305 (FIG. 41) according to the present invention and a blade-shaped current collector 306 (FIG. 41) used in a conventional streamline current collector. 42) schematically shows the surrounding flow in 42). In the current collector 305 according to the present invention, vertical vortices suppress vortices with a uniform phase that easily cause noise, and suppress noise generation.

43 and 44 schematically show the pressure distribution on the surface. As shown in FIG. 44, in the case of the conventional two-dimensional blade 308, since the wake is two-dimensional, the surface pressure is also uniform and two-dimensional in the width direction of the blade 308. On the other hand, in the blade 307 of the present invention, which has a tip surface with both ends retracted, the pressure is not evenly distributed in the lateral direction of the current collector 22 as shown in FIG. .

In order to reduce the aerodynamic noise generated by the flow around the connecting portion between the current collector 22 and the supporting column 400, as shown in FIG.
As shown in FIG. 5, the connection portion 40 between the current collector 22 and the support column 400
Connect 2 with a curve. Alternatively, the connecting portions may be connected with a polygon so that the connecting portions do not have an acute angle. When the connection portion between the current collector 22 and the support column 400 has an acute angle or a right angle, a secondary flow occurs in that portion and aerodynamic noise is generated. A sudden change in the flow near the wall surface tends to generate noise. As in the present invention, the use of smooth connections reduces noise. In particular,
The length S ₂ of the contact portion between the smooth curved surface and the current collector 22 is about one third of the length S ₁ in the longitudinal direction of the current collector 22,
The noise reduction effect is great when the length S _{3 of the} portion in contact with the support column 400 from the lower surface of the current collector 22 is about one sixth of the longitudinal length S ₁ of the current collector 22.

FIG. 46 shows a result of noise comparison with a conventional current collector by conducting a wind tunnel experiment using a model of the current collector according to the present invention. The current collector (circle) according to the present invention is about 20 dB compared to the current collector according to the prior art, and even compared to the streamline current collector.
A noise reduction effect of 5 dB or more can be obtained.

The current collector 22 may have a blade cross section, and the tip surfaces on both outer sides may recede with respect to the central portion. In such a current collector 22, since the ridge line extends along the receding direction of the current collector 22, the contact plate 21 on the ridge line is unlikely to generate vortices that are even and have a uniform phase in the lateral direction, and therefore noise is small. Become.

[0137]

[Embodiment 10] As another embodiment of the present invention, as shown in FIG. 47, two front and rear collectors 22 each having a shape in which both outer end surfaces 22A are set back with respect to a central portion 22B are combined. , (In plan view) may be a rhombic current collector. That is, by configuring the current collector 22 to have a shape in which the front end surface recedes from the center around the traveling direction as it goes in the longitudinal direction and is symmetrical with respect to the front-rear direction, the longitudinal vortex-generated noise with longitudinal vortex is generated. A small shape can be realized.

Further, in order to reduce the generation of blade tip vortices and to guide the crossovers, the upper and lower sides of the current collector 22 which are in contact with the overhead line L may be formed as convex curved surfaces. Good.

[0139]

Eleventh Embodiment As another embodiment of the present invention, a current collector 22
May be placed on the turntable, and the turntable may be rotated according to the traveling state so that the front end of the current collector 22 faces the traveling direction of the vehicle. According to this method, the number of current collectors 22 to be mounted on the vehicle can be reduced.

[0140]

[Embodiment 12] FIG. 48 shows another embodiment of the present invention. In this example, the maximum thickness (h _max ) position P of the vertical cross section of the current collector 22 is shown.
From the tip of the current collector 22 to the chord length (c) of the current collector 22
Of 30% of the current collector 22 and the upper surface near the trailing edge of the current collector 22 has a concave curved surface shape. It was confirmed by a wind tunnel experiment that when the shape of the current collector 22 is the above-mentioned shape, the pressure drop from the maximum pressure point to the trailing edge becomes gradual and the aerodynamic noise decreases. Therefore, the cross-sectional shape of the current collector 22 according to the present invention is effective in reducing the noise of the current collector. Further, in this case, the effect is high when the basic shape of the current collector 22 is vertically symmetrical.

It was.

[Embodiment 13] FIG. 49 shows another embodiment of the present invention. By making the support column 400 of the current collector 22 into a cone or an elliptic cone 400a that is less likely to generate aerodynamic noise, the flow around the support column is changed in the height direction to make the flow three-dimensional and suppress noise generation. .

[0142]

[Embodiment 14] FIG. 50 shows another embodiment of the present invention. When the sliding plate 21 has a two-dimensional shape and generates a large amount of aerodynamic noise, the current collector 22 is located in the vicinity of the front edge of the sliding plate 21 near the front edge, in a position where the width of the sliding plate 21 is narrower, and in the traveling direction of the vehicle. At least one or more long protrusions 222 are arranged, and these protrusions generate a vertical vortex to suppress the Karman vortex-like aerodynamic noise generated by the contact plate 21. Especially the protrusion 2
When three or more 22 are arranged within the width of the contact plate 21, the noise reduction effect is great.

FIG. 51 shows the results of examining the noise reduction effect of the present invention by a wind tunnel experiment. The vertical vortex generating protrusion 222 according to the present invention is effective in reducing noise.

According to the embodiment of the present invention, by using a current collector having a shape receding in the longitudinal direction as a current collector of a high-speed railway vehicle, a vertical vortex is positively generated on the current collector.
The effect of reducing aerodynamic noise can be obtained by suppressing the generation of a two-dimensional vortex with a uniform phase, that is, a vortex that easily generates aerodynamic noise, as in a conventional current collector. Moreover, not only is the support of the current collector made streamlined, but the connection between the current collector and the support is made by the current collector so that the secondary flow is minimized at the connection between the current collector and the support. By smoothly connecting the vertical vortices so that they do not interfere with each other, the effect of reducing the aerodynamic noise generated from the current collector and the column connecting portion can be obtained.

In another embodiment of the present invention, the effect of reducing aerodynamic noise caused by the two-dimensional flow generated by the current collector by creating a three-dimensional flow by the duct generating the swirling flow is obtained. .

Further, in another embodiment of the present invention, a part of the current collector is movable, has a function of pulling in the connecting wire of the overhead line at low speed, and reduces the noise at high speed. It becomes horizontal and becomes a form of low aerodynamic noise. This will not hinder the replacement of overhead lines at low speeds,
It is possible to obtain a form with low noise when traveling at high speed.

[0147]

According to the present invention, since the current collecting function portion, that is, the current collecting member, the driving function portion for driving the current collecting member and following the overhead wire, and the power conducting function portion are separately configured, the current collecting function is achieved. The part becomes lighter and smaller, and it is possible to improve the control characteristic of following an overhead line while traveling at high speed. In addition, the function of collecting electric power is completely ensured.

Further, a streamlined storage dome is provided on the upper part of the vehicle, and the drive mechanism is always positioned inside the dome.
Since the current collecting function part is housed when it is not collecting current, it is possible to suppress the generation of noise.
