As indicated by arrows in this figure, air flows in through the air holes 13 b and 13 c at the top of the duct 13 or the air hole 13 d at the bottom, passes through the damper 140, and flows into the region 24. At this time, the air that has passed through the damper 140 is heated by the infrared heater 121. Part of the air that has passed through the damper 140 is supplied to the engine 100 after dust is filtered by the air filter 120. The other air is supplied to the radiator 110 after the engine 100 is cooled. The air that has passed through the radiator 110 passes through the damper 150, then passes through the duct 14, and is discharged through the upper air holes 14b and 14c (not shown) or the lower air hole 14d (not shown). . The exhaust gas of the engine 100 passes through the muffler 131 and is then discharged from the exhaust pipe 14a to the outside.

  The power failure detection sensor 10d 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), a power failure occurs in the control unit 30. Notify that.

  The switch 10e is an electromagnetic contactor or the like that is controlled by the control unit 30 and the connection direction is selected. In the normal state, the switch 10e selects the output of the commercial power source 1 and outputs it to the electrical facility 2. Is selected and 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 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 10d, 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 10e is switched to the commercial power source 1 side and the engine 100 is stopped. Further, as will be described later, when the air temperature in the regions 22 to 24 is lower than a predetermined temperature, the control unit 30 energizes the heater 10b so that the internal temperature of each region does not become below a certain level. To control.

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

  FIG. 19 is a diagram for explaining the operation of the embodiment of the present invention. When the processing of the flowchart shown in this figure is started, the following steps are executed.

  Step S10: The control unit 30 refers to the output of the temperature detection sensor 31, and detects the internal temperature Ti (the temperature of each region) of the housing 11.

  Step S11: The control unit 30 determines whether or not the internal temperature Ti is lower than a predetermined set temperature Tt1, and proceeds to step S12 if the internal temperature Ti is lower, otherwise proceeds to step S13. For example, if the internal temperature Ti is lower than −5 ° C., the process proceeds to step S12.

  Step S12: The control unit 30 operates the heater 10b to increase the internal temperature. That is, the control unit 30 starts energizing the space heaters 33, 34, 61.

  Step S13: The control unit 30 determines whether or not the internal temperature Ti is higher than a predetermined set temperature Tt2. If it is higher, the control unit 30 proceeds to step S14, and otherwise proceeds to step S15. For example, if the internal temperature Ti is higher than 0 ° C., the process proceeds to step S14.

  Step S14: The controller 30 stops energization of the heater 10b. That is, the control unit 30 stops energizing the space heaters 33, 34, 61. At this time, the blower fan 35 may be operated to forcibly circulate the air in the regions 22 to 24.

  Step S15: The control unit 30 detects the external temperature (outside air temperature) To of the housing 11.

  Step S16: The control unit 30 proceeds to step S17 when the external temperature To of the casing is lower than the predetermined temperature Tt3, and proceeds to step S18 in other cases. For example, when the external temperature To is lower than 0 ° C., the process proceeds to step S17.

  Step S <b> 17: The control unit 30 supplies power to the infrared heater 121 and starts heating the damper 140. As a result, even when the damper 140 is frozen, the damper 140 can be easily opened and closed by melting it.

  Step S <b> 18: The control unit 30 stops supplying power to the infrared heater 121. Note that a difference may be provided between the operating temperature and the stop temperature of the infrared heater 121. According to such a configuration, the infrared heater 121 can be prevented from being frequently turned on or off at a temperature near the threshold (Tt3 in this example). It is also possible to set the operation and stop temperature of the infrared heater 121 to the same temperature as the space heaters 33, 34, 61.

  Step S19: The control unit 30 refers to the output of the power failure detection sensor 10d and detects the occurrence of a power failure.

  Step S20: The control unit 30 determines whether or not a power failure has occurred. If a power failure has occurred, the control unit 30 proceeds to step S21. Otherwise, the control unit 30 returns to step S10 and repeats the same processing.

  Step S21: The control unit 30 supplies DC power from the battery 32 to a cell motor (not shown), and starts the engine 100. At this time, the area 24 where the engine 100 is installed is controlled by the space heater 61 to be in the range of Tt1 to Tt2, and since the air warmed by the infrared heater 121 is sucked, the outside air is Even when the temperature is below freezing, engine 100 can be easily started.

  Step S22: The control unit 30 supplies power from the generator 60 to the damper opening / closing motors 140a and 150b and sets them to the open state (the state shown in FIG. 13). At this time, since engine 100 has already been started, operation of engine 100 can be maintained even when damper 140 is opened. In other words, the engine 100 may be less startable at temperatures below freezing, but once started, the engine 100 is warmed by the heat generated by the engine 100 itself, so operation can be maintained.

  Step S23: The control unit 30 switches the switch 10e from the commercial power source 1 side to the generator 60 side. As a result, since the electric power generated by the generator 60 is supplied to the electric facility 2, the electric facility 2 can maintain its operation.

  Step S24: The control unit 30 refers to the output of the power failure detection sensor 10d and detects power recovery (elimination of power failure).

  Step S25: The control unit 30 determines whether or not the power has been restored (whether or not the power failure has been resolved). If the power has been restored, the process proceeds to step S26. Otherwise, the process returns to step S24 and the same. Repeat the process.

  Step S26: The control unit 30 switches the switch 10e to the commercial power source 1 side. As a result, electric power is supplied from the commercial power source 1 to the electrical equipment 2.

  Step S27: The control unit 30 stops the engine 100.

  Step S28: The control unit 30 controls the damper opening / closing motors 140a and 150a so that the dampers 140 and 150 are closed (the state shown in FIG. 12). As a result, the inflow of air from the outside is eliminated, so that warm air can be prevented from leaking to the outside.

  Step S29: The control unit 30 determines whether or not to end the process. If not, the control unit 30 returns to step S10, repeats the same process, and otherwise ends the process.

  As described above, in the power generation device 10 according to the embodiment of the present invention, when the temperature inside the casing 11 becomes equal to or lower than the predetermined temperature, the space heaters 33, 34, 61 are energized. Since the temperature is increased and the dampers 140 and 150 are provided and are closed when not required, the engine 100 can be smoothly started even in a cold region.

  Moreover, since the dampers 140 and 150 are opened after the engine 100 is started, the engine can be started smoothly, and after the start, the engine can be sufficiently cooled to maintain smooth rotation.

  In addition, since the infrared heater 121 is provided to heat the damper 140, the damper 140 can be smoothly opened and closed even when the damper 140 is frozen. Further, since the air filter 120 is disposed in the vicinity of the infrared heater 121, the engine 100 can be easily started by the air heated by the infrared heater 121.

  Further, the partition plate 21 separates the upper part where the control unit 30 and the like are arranged from the lower part where the engine 100 and the like are arranged, so that it is possible to keep the temperature most suitable as each operating environment.

  Further, since the blower fan 35 is provided in the partition plate 21 and the upper air is forced to circulate in the lower part, for example, it is possible to prevent the upper temperature from rising excessively in summer.

  Furthermore, by making the wall constituting the housing 11 into a hollow structure and filling the inside with the heat insulating material 11a, the inside of the housing 11 can be maintained at an optimum temperature even with a small amount of power.

  In addition, Tt1-Tt3 mentioned above can be set arbitrarily. When a space heater or the like is used, the startability of the engine 100 can be improved. However, since power consumption is generated by that amount, in order to keep the startability of the engine 100 and to keep power consumption low, the installation environment It is desirable to set it optimally according to.

  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, although the infrared heater 121 is provided only on the damper 140 side, it may be provided also on the damper 150 side. Further, a heat source other than the infrared heater may be used. Further, by applying a mechanical impact to the dampers 140 and 150 instead of the infrared heater (for example, by applying an impact force by electromagnetic force), icing of the dampers 140 and 150 is excluded, and these easily open and close. You may do it.

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