In addition to this, a fuel filter, a cell motor, a heater, and the like are provided, but the description thereof is omitted.

  FIG. 11 is a block diagram illustrating an electrical configuration of the power generation apparatus 10.

  As shown in this figure, the power generation apparatus 10 includes a power failure detection sensor 10a, a switch 10b, an AVR (Auto Voltage Regulator) 30b, a generator 60, an engine 100, a control unit 30, and an operation unit 30a.

  Here, the power failure detection sensor 10a constantly monitors the commercial power source 1, and when a power failure occurs (that is, when the output of the commercial power source becomes lower than a predetermined threshold), the power failure detection sensor 10a notifies the control unit 30 of the power failure. Notify that has occurred.

  The switch 10b is an electromagnetic relay or the like that is controlled by the control unit 30 and the connection direction is selected. In the normal state, the switch 10b selects the output of the commercial power source 1 and outputs it to the electrical equipment 2. When a power failure occurs, the output of the generator 60 Is output to the electrical equipment 2.

  The AVR 30b is a control device that controls the output of the generator 60 to be a predetermined voltage. The generator 60 is driven by the engine 100 and outputs AC power having the same voltage and frequency as the commercial power source 1. The AVR 30b is built in the control unit 30.

  The engine 100 includes, for example, a diesel engine, a gasoline engine, a gas turbine, and the like, and rotates by burning fuel (for example, light oil, gasoline, hydrogen, methanol, etc.) stored in a fuel tank 80 shown in FIG. And the generator 60 is driven.

  When the occurrence of a power failure is detected by the power failure detection sensor 10a, the control unit 30 rotates the cell motor (not shown) to start the engine 100. After the engine 100 is started, the controller 60 generates a predetermined voltage and The number of revolutions of engine 100 is controlled so that electric power having a frequency is output. Further, when the power failure is resolved, the switch 10b is switched to the commercial power source 1 side and the engine 100 is stopped. Moreover, the control part 30 is controlled so that the internal temperature of the housing | casing 11 may not become below a fixed temperature by supplying with electricity to the heater which is not shown, when installing in a cold region. As a result, the engine 100 can be easily started even in a cold region where the temperature drops below freezing (for example, the temperature drops near minus 30 degrees).

  The operation unit 30a is configured by, for example, a touch panel for inputting information when the administrator performs various settings.

  The electrical equipment 2 is, for example, a road equipment such as a traffic light, an outdoor work facility, and the like, and normally operates by power from the commercial power source 1 and operates by power generated by the generator 60 during a power failure.

  Next, the operation of the above embodiment will be described.

  The power generation device 10 of the present invention is installed in, for example, a cold region or a heavy snowfall region. When a power failure occurs for some reason, the power failure detection sensor 10a detects this and notifies the control unit 30 of it. Control unit 30 recognizes that a power failure has occurred, starts rotation of a cell motor (not shown), and starts engine 100.

  When engine 100 is started, generator 60 is rotated to generate AC power. The AVR 30b controls the generated AC power to be a predetermined voltage. Control unit 30 controls the rotational speed of engine 100 so that the electric power output from generator 60 has a predetermined frequency. When the rotation of engine 100 is stabilized and the AC voltage output from generator 60 is stabilized, control unit 30 switches switch 10b from the commercial power supply 1 side to the generator 60 side. As a result, the AC power generated by the generator 60 is supplied to the electrical facility 2, so that the electrical facility 2 can operate even in the case of a power failure.

  And when a power failure is eliminated, the control part 30 recognizes this with the output from the power failure detection sensor 10a, and switches the switch 10b to the commercial power source 1 side. As a result, electric power is supplied from the commercial power source 1 to the electrical facility 2. Then, control unit 30 stops engine 100 and completes the operation.

  By the way, since the electric power generating apparatus 10 has the engine 100, it is necessary to maintain regularly, for example, changing oil, supplying fuel, or confirming operation | movement. An operation method in such a case will be described below.

  First, the case where the electric system is maintained will be described. In that case, the administrator opens the door 15 by operating the handle 15a of the power generation apparatus 10 shown in FIG. At this time, the door 16 remains closed. In this state, since the generator 60 and the engine 100 are shielded from the outside by the lid 40, the electric system can be safely maintained without paying attention to the rotating portion even when the engine 100 is in operation. It can be carried out. At that time, the electric system can be completely disconnected by operating the changeover switches 54 and 55.

  On the other hand, when the fuel is replenished, the handle 16a shown in FIG. 4 is operated to open the door 16 to the state shown in FIG. At this time, if the cover 90 is closed, even if the engine 100 is operating, it is possible to refuel safely without paying attention to the rotating part.

  Furthermore, when performing maintenance of the engine 100 and the generator 60, it is possible to access a desired part of the apparatus from the front or the back if the lids 40 and 90 are opened, so that maintenance work can be performed. It becomes possible to carry out easily.

  As described above, in the power generation apparatus 10 according to the embodiment of the present invention, since the two doors 15 and 16 are provided, it is possible to work by opening the door according to the purpose. For this reason, for example, when maintaining the electric system, it is possible to operate the operation unit 30a or perform maintenance of other parts by opening the door 15. Further, when fuel is replenished, the fuel can be replenished by opening the door 16. Further, by opening both the doors 15 and 16, it becomes possible to easily access a desired part of the apparatus, so that maintenance work can be easily performed.

  Further, since the generator 60 and the control unit 30 are disposed on the door 15 side, and the engine 100 and the fuel tank 80 are disposed on the door 16 side, the door 15 is opened during maintenance of the electric system, and maintenance of the power system is performed. In some cases, opening the door 16 makes it possible to access a necessary part.

  In addition, since the ducts 13 and 14 are provided on the side surfaces orthogonal to the doors 15 and 16, it is possible to secure the air flow and prevent the ducts 13 and 14 from interfering with each other to prevent the maintenance work from being performed smoothly. .

  In addition, since the lid 40 and the lid 90 are provided, it is possible to perform maintenance work safely without paying attention to the rotating portion even when the engine 100 is operating.

  Further, by providing the lids 40 and 90, it is possible to prevent the outside air from flowing into the region 24 where the engine 100 is installed even when the doors 15 and 16 are opened in a cold region. 100 can be started quickly.

  In addition, by providing the lids 40 and 90, for example, when the engine 100 is operated in the summer, it is possible to prevent heat generated by the engine 100 from being transmitted to the regions 22, 23 and the like by convection. It is possible to prevent the electrical system from being stressed by heat.

  In addition, the power distribution unit (for example, the terminal blocks 51 to 53 and the changeover switches 54 and 55) generated by the generator 60 is disposed in the lid 40 together with the generator 60. By shielding the voltage portion with the lid 40, it becomes possible to perform maintenance work safely.

  The above-described embodiments are preferred examples of the present invention, but the present invention is not limited to these, and various modifications and changes can be made without departing from the scope of the present invention. is there.

  For example, in the above embodiment, the generator 60 is arranged on the door 15 side and the engine 100 is arranged on the door 16 side, but other arrangements may be employed.

  Moreover, although the control part 30 was provided in the area | region 22 and the temperature detection sensor 31 and the battery 32 were provided in the area | region 23, arrangement | positioning other than this may be sufficient.

  In addition, although the two lids 40 and the lid 90 are provided, for example, only one lid may be provided. For example, since the door 16 is opened when refueling, the frequency of opening and closing is low, and thus the lid 90 can be omitted. In that case, for example, the lid 90 may be formed integrally with the door 16 so that the lid 90 is opened and closed according to the door 16.

  Further, the lids 40 and 90 are locked by an electromagnetic lock or the like so that they cannot be removed unless the predetermined release operation is performed on the operation unit 30a of the control unit 30 during the operation of the engine 100, for example. It may be. According to such an embodiment, it is possible to further improve safety during maintenance work.

  Further, although the ducts 13 and 14 have a T-shape, it goes without saying that other shapes may be used.
