Description

The present invention relates to a mobile power supply vehicle including two sets of generators inside a housing provided on a cargo bed.

A mobile power supply vehicle equipped with a power generation device is used for a wide range of purposes such as an emergency power supply in the event of a power outage or a disaster, or a power supply for various exhibitions, because of its mobility. By the way, this mobile power supply vehicle is equipped with a set of a power generation system such as a power generator, a power generation control device, and an engine in a housing. In such a mobile power supply vehicle, if the generator or the engine fails, it becomes impossible to supply power to the important load, so it is desirable to mount two sets of power generation systems.
For example, as an example of a mobile power supply vehicle equipped with two sets of generators, there is a mobile power supply vehicle described in Patent Document 1. In the mobile power supply vehicle of Patent Document 1, two sets of power generation systems including a generator, an engine, a radiator, and a duct are arranged in series in the front-rear direction of the vehicle.

When the devices of the two power generation systems are arranged in the same order as in Patent Document 1, it is necessary to secure an installation space for the two power generation systems. However, since there is a limit to the front-rear dimension of the housing that can be mounted on the mobile power supply vehicle (vehicle), there is a fear that two sets of power generation systems cannot be accommodated in the housing in the layout as disclosed in Patent Document 1. There is.

Therefore, an object of the present invention is to provide a mobile power supply vehicle in which the size of the housing in the front-rear direction is reduced.

In the present invention, the mobile power supply vehicle is provided with a housing provided on a bed of the vehicle, a first generator arranged in a front region of the housing, and a rear portion of the first generator. A first engine that drives a first generator, a first fan and a first radiator that are located behind the first engine, and a second generator that is arranged in a rear region of the housing. A second engine located in front of the second generator and driving the second generator; a second fan and a second radiator located in front of the second engine; A duct positioned between the first radiator and the second radiator, the duct having an opening facing the first radiator and an opening facing the second radiator. A closing mechanism is provided in the duct to cover the stopped generator-side opening when the first generator or the second generator is stopped.

Therefore, in the casing of the mobile power supply vehicle, the first generator, the first engine and the first radiator are centered around the second generator, the second engine and the second radiator, and a single duct. Are arranged symmetrically .

According to the present invention, by mounting two sets of power generation systems in a vehicle, an unused power generation system can serve as a backup when a power generation system in operation fails. In addition, since a common duct is provided instead of individually providing a duct for each of the first generator and the second generator, it is possible to reduce the space occupied by the duct in the housing of the mobile power supply vehicle. .. As a result, the front-rear dimension of the housing mounted on the mobile power supply vehicle is shortened. Further, the closing mechanism closes the opening of the power generation system that is stopped, and the air of the power generation system that is operating is discharged to the outside of the housing through the duct and does not flow into the power generation system that is stopped.

Further, the two fuel tanks 21A and 21B may be one fuel tank.

Two exhaust doors 22A, 22B are provided in the upper part of the duct 15 so that the air passing through the openings 14A, 14B and the exhaust gas from the exhaust pipes 11A, 11B are exhausted to the outside of the housing 4 through the duct 15. There is. The two discharge doors 22A and 22B are made of, for example, aluminum. As shown in FIGS. 3 and 4, the discharge doors 22</b>A and 22</b>B include a plate-shaped lid portion 24 that is lifted in parallel with the ceiling surface 23 of the housing 4, and four downwardly extending four corner portions of the lid portion 24. The rod-shaped leg portion 25 (only two leg portions 25 are shown in FIGS. 3 and 4) and both side portions 24a of the lid portion 24 are arranged so as to extend in parallel with both side wall portions 26 of the housing 4. Two fixed grip portions 27 are provided, respectively. The four leg portions 25 are provided on the inner sides of the side wall portions 26 in parallel with the side wall portions 26, and the four side portions of the two plate-shaped guide rails 28 (along the vertical direction in FIGS. 3 and 4). You will be guided along the side. In this embodiment, the discharge doors 22A and 22B are manually opened and closed by the operator moving the handle portion 27. Alternatively, for example, an actuator may be used to automatically open and close the discharge doors 22A and 22B.

The two discharge doors 22A and 22B are always opened during operation of the front power generation system or the rear power generation system, and are open in both the front-rear direction and the width direction of the mobile power supply vehicle 1. At this time, since the lid portion 24 is lifted up in parallel with the ceiling surface 23 of the housing 4, the outside air flowing along the ceiling surface 23 flows into the duct 15 from between the lid portion 24 and the ceiling surface 23. Never.

If it is assumed that the lid of the discharge door is opened and closed around the hinge provided on the ceiling surface of the housing, the outside air flowing along the ceiling surface of the housing when the lid is opened. , Collides with the inclined lid and flows into the duct. Then, the air that has flowed into the duct collides with the air that has become hot due to, for example, cooling the generator or the like, whereby heat is trapped in the duct. Therefore, in this embodiment, by raising the lid portion 24 in parallel with the ceiling surface 23 of the housing 4, the outside air does not flow into the duct 15, and the flow of the air to be discharged is not blocked by the outside air. ..

It should be noted that instead of providing the two discharge doors 22A and 22B above the duct 15, one discharge door larger than the discharge door 22A or the discharge door 22B may be provided.

Further, as shown in FIG. 2, in the side wall portions 26 of the housing 4 which are parallel to each other, two intake ports 30 having a rectangular cross section are formed in both the front region 4A and the rear region 4B of the housing 4. There is. As shown in FIG. 3, the intake port 30 is provided with an intake door 31 for opening and closing the intake port 30.

Therefore, the opening 14B of the rear wall portion 13B is closed by the fixed partition plate 18 and the slanted movable partition plate 20.

Then, by driving the front side fan 7A, air is taken in from the outside of the housing 4 through the two front side intake ports 30 and cools the front side generator 5A, the front side diesel engine 6A and the front side radiator 8A. .. The air that has cooled these devices flows into the duct 15 from the opening 14A of the wall 13A on the front side by the blowing of the fan 7A on the front side, as shown by an arrow A in FIG. It is discharged from the two discharge doors 22A and 22B.

In the above embodiment, the fixed partition plate 18 and the slanted movable partition plate 20 close the opening 14B of the wall 13B of the stopped rear power generation system, so that the air that has flowed into the duct 15 through the opening 14A is not supplied. , Does not pass through the opening 14B and does not flow into the rear power generation system. Further, the inclined movable partition plate 20 allows the air from the opening 14A to smoothly flow along the inclination of the movable partition plate 20.

On the other hand, the exhaust gas from the front diesel engine 6A flows into the vicinity of the upper portion of the duct 15 through the front exhaust pipe 11A above the front diesel engine 6A as shown by an arrow G in FIG. Exhausted from 22A and 22B.

Further, when the rear power generation system is operated and the front power generation system is stopped, the two rear intake doors 31 are opened, and further, in the closing mechanism 17, the movable partition plate 20 is opened on the front side. It can be manually or automatically switched to close the portion 14A. Then, by driving the rear fan 7B, air flows into the duct 15 through the rear opening 14B.

In this embodiment, the air from the opening 14B is blocked by the fixed partition plate 18 and the inclined movable partition plate 20, does not pass through the opening 14A, and does not flow into the front power generation system. Further, the air from the opening 14B flows smoothly along the inclination of the movable partition plate 20.

As described above, in the present embodiment, the front side generator 5A, the front side diesel engine 6A, the front side fan 7A, the front side radiator 8A, the rear side generator 5B, the rear side diesel engine 6B, the rear side fan 7B, The rear radiator 8B and the duct 15 are symmetrically arranged. Therefore, instead of providing a separate duct for discharging each of the air that has cooled the front side generator 5A and the like and the air that has cooled the rear side generator 5B and the like, the common duct 15 having the closing mechanism 17 is provided. Since it is used, the space occupied by the duct 15 in the housing 4 of the mobile power supply car 1 can be reduced. As a result, the size of the housing 4 mounted on the mobile power supply vehicle 1 in the front-rear direction is shortened.

Further, in the above-described embodiment, since the two fuel tanks 21A and 21B are accommodated in the dead space in the duct 15, the size of the housing 4 can be further reduced.

Further, in the above-described embodiment, since the front exhaust pipe 11A and the rear exhaust pipe 11B communicate with the duct 15, the exhaust gas from the front exhaust pipe 11A and the rear exhaust pipe 11B is passed through the common duct 15 to the casing 15. It can be vented to the outside of the body 4.

Although the front side generator 5A and the rear side generator 5B having the same power generation capacity are disclosed in the above-described embodiments, the front side generator 5A and the rear side generator 5B have different power generation capacities. May be configured as. Similarly, the front diesel engine 6A and the rear diesel engine 6B may be configured to have different displacements.

Further, in the above-described embodiment, only one of the front side power generation system and the rear side power generation system operates, but, for example, when switching between the front side and rear side power generation systems, the fixed partition plate 18 and the movable partition plate are used. It is also possible to rotate the movable partition plate 20 so that the 20 and 20 are aligned on a straight line, and temporarily operate both the front side generator 5A and the rear side generator 5B.
