Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile power generation facility device which has taken measures against cold regions to ensure reliability in starting and power generation.

[0002]

2. Description of the Related Art A mobile power generation facility device (also referred to as a mobile power supply vehicle) is a device for supplying electric power to an electric load with mobility in place of a regular power supply and easily, and includes a prime mover system and an electric system. It is installed in a truck or trailer, and the main configuration diagram when the prime mover is a diesel engine is shown in Fig. 3.

In FIG. 3, reference numeral 1 is a freight vehicle, and a box-shaped soundproof package body 2 is formed on the bed of the vehicle 1. Inside the soundproof package main body 2, a prime mover 3, a generator 4 driven by the prime mover 3, a control panel 5 for controlling and monitoring the output from the generator 4, and exhaust sound from the prime mover 3. An exhaust silencer 6 for extinguishing, a radiator 7 for cooling the prime mover 3, a cable 8 for connecting the generator 4 and a distribution line, and the like are stored. In addition, 9 is an output connection box, 10 is a battery, and 11 is a fuel tank. Further, the prime mover system includes a prime mover such as the above-described diesel engine and an accessory device thereof, and the electric system includes a generator and various control devices for the prime mover and the generator.

The mobile power supply vehicle constructed as shown in FIG. 3 is used even in remote areas of the mountains regardless of urban areas because of its mobility. Therefore, depending on the location where the mobile power supply vehicle is used, the ambient temperature may be -30 ° to 40 ° C depending on the area.
It is also used in the range of °. In particular, in use in a cold region where the temperature is as high as -30 °, means for ensuring the reliability of starting and power generation establishment are required for both the prime mover system and the electric system.

In general, both the prime mover system and the electric system need to have a specified temperature at which they can operate at the time of starting power generation. Therefore, one of the measures to keep warm during standby is to perform constant preheating by an external power source (engine oil pan heater, controller space heater, generator space heater, etc. are used for this preheating).
It secures starting and power generation in cold regions.

[0006]

As a measure for starting the engine in cold regions, use of appropriate fuel, lubricating oil, mixing of cooling water antifreeze, preheating with an external service power source such as preheating with a battery just before starting, and so on. Even if it is not necessary, it is possible to take measures to start in cold regions. However, control devices including a composite circuit of various electric parts and elements are restricted by the operable temperature of the parts used. That is, various electric parts and elements have an operating temperature and a storage temperature, and the lower limit of the operating temperature of the semiconductor elements, which has greatly contributed to downsizing and performance improvement of the device in recent years, is 0 to − Most of them are about 10 °. (Note that the storage temperature is generally -40 ° C or less in most cases.) Therefore, no matter how much the engine could be started in cold climate starting measures (such as preheating measures just before starting using battery power). If the control devices do not reach the operable lower limit temperature at this point, control for establishing a reliable power generation state cannot be performed. On the other hand, in order to keep the above-mentioned control devices in a preheated state, conventionally, it has been necessary to provide a space heater on a control panel accommodating various control devices and supply an external regular power source to preheat during standby. It was For this reason,
An external regular power supply facility (usually AC100
V output) was required. As a result, for example, it is not useful at the time of starting at a work site in a cold region where a regular power supply cannot be obtained nearby.

The present invention has been made in view of the above circumstances, and eliminates the need for a preheating device for a prime mover and various control panels by a regular power source, and ensures reliable starting and power generation even in a place where a regular power source is not available. It is an object of the present invention to provide a mobile power generation facility device that preheats the entire area of the package body so that it can be heated.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a first aspect of the present invention, in which a power generating facility for mobile use is installed in which a component of a prime mover system and an electric system is housed and mounted in a package body. In the above, the hot air manufacturing device is arranged at a position different from the package body, and the hot air manufacturing device is configured to blow hot air into the package body for preheating the components of the prime mover system and electric system. It is characterized by having done.

The second aspect of the invention is characterized in that the fuel supplied to the warm air producing apparatus is taken from the fuel tank of the mobile power generation facility.

A third aspect of the invention is characterized in that a temperature detecting device is provided in the package body, and the operation of the warm air producing device is stopped when the temperature in the package body reaches a set temperature.

[0011]

[Operation] When the warm air manufacturing apparatus is operated while the moving power generation equipment is moving or stopped and hot air is blown into the package body to raise the temperature inside the package body to the set temperature, each of the prime mover system and the electrical system The components become operational. In this way, by operating the equipment, it is possible to reliably establish power generation even in cold regions.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same parts as those in FIG.
In FIG. 1, a warm air manufacturing apparatus 21 is provided at the lower rear of the cargo bed of the freight vehicle 1. As shown in FIG. 2, the warm air producing apparatus 21 burns the fuel guided from the fuel tank 11 by the fuel pipe 22, exhausts the exhaust gas generated by the combustion from the exhaust gas exhaust port 23, and obtains it by the combustion. The warm air thus blown is blown into the package body 2 through a warm air outlet 24 provided in the package body 2. In addition,
Reference numeral 25 is a warm air intake, and 26 is a combustion air intake.

Although not shown in the figure, the warm air producing apparatus 21 is constructed so as to be able to carry out operation control and stop control without starting the vehicle running engine so that temperature control and time schedule operation can be performed. It has become. The warm air outlets 24 are provided at both edges of the package body 2 in the longitudinal direction.

In the mobile power supply vehicle configured as described above,
Prior to using the mobile power supply car in a cold region, warm air produced by the warm air producing device 21 is sent into the package body 2 to raise the temperature of the package body 2. As a result, the prime mover 3, the generator 4, and various control devices of the package body 2 are also preheated. A temperature detecting device (not shown) is provided in the package body 2 so that when the operating temperature of the control devices reaches a set temperature, the power generation equipment is started and the operation of the hot air manufacturing device 21 is stopped.

As a specific example, a hot air producing apparatus having a capacity of 6000 kcal / hr was used when the lower limit temperature of operation of the control devices was −5 ° C., the volume of the soundproof package main body was 15 m ³ , and the ambient temperature condition was −30 ° C. In this case, the temperature in the main body rises to about -5 ° C in about 30 minutes. This required heating time can be appropriately adjusted by selecting a hot air manufacturing apparatus having various capabilities.

To summarize the above, the above-described embodiment is a mobile power generation facility, which has conventionally been supplied with an external regular power source, preheats each constituent device of a prime mover system and an electric system, and can start operation even in a cold region. On the other hand, it is possible to warm up the entire package body with warm air before starting operation, so it is possible to use preheating with a warm air manufacturing device to a temperature that does not hinder the operation of each component. It was done.

By systematically incorporating the warm air production apparatus configured as described above into the mobile power generation equipment, the operation of the hot air production apparatus is added to the operating conditions in the cold district, and the temperature inside the package body is adjusted to a desired value. When the temperature is reached, the start of the power generation facility and the power generation command are accepted, and the operation of the hot air manufacturing apparatus is stopped, so that the facility can be reliably started in the cold district.

Since the above-described hot air producing apparatus directly obtains hot air by burning fuel, it is small in size and high in calories. Therefore, it is possible to increase the temperature in the package body more rapidly than the space heater by heating the electric heater. As a result, main components can be preheated during power transmission preparation work such as cable laying before power generation. Further, even while moving from the parking place to the work site, preheating can be completed by operating the warm air manufacturing apparatus.

In the above embodiments, the preheating means for the mobile power generation equipment has been described. However, the present invention is directed to another vehicle-mounted device in which the main components of the prime mover system and the electric system other than the mobile power generation equipment are housed in the package body. It can also be applied to preheating means for in-vehicle equipment in cold regions such as mechanical equipment for moving vehicles and electric equipment (for example, drain pipe cleaning vehicles, radio relay vehicles and pump vehicles).

[0020]

As described above, according to the present invention,
A preheater for the prime mover and various control panels by an external regular power supply can be eliminated, and even in places where the regular power supply is not available, the entire package body can be preheated before the actual power generation. There is an advantage that reliable starting and power generation can be established even on the ground. Further, except for mixing the antifreeze liquid into the prime mover having the cooling water system, it is not necessary to install a preheating device such as a heater here for each component of the prime mover system and the electric system.
