  Further, as shown in FIG. 6, since the heat insulation member 11 a is filled inside the wall constituting the housing 11, the heat transmitted through the spaces 12 g to 12 j or the support plates 12 b to 12 f is also concerned. It is not easily transmitted to the inside of the housing 11 by the heat insulating member 11a. Further, since a space 11 e is formed between the inner upper surface 11 d of the housing 11 and the fuel tank 80 and the control unit 30, heat is transmitted to the fuel tank 80 and the control unit 30 and stored in the fuel tank 80. Heat can be prevented from being transferred to the fuel or the semiconductor components incorporated in the control unit 30.

  Furthermore, since engine 100 and generator 60 are arranged in a space sealed by partition plate 70, lids 40, 90, etc., they are stored in fuel tank 80 by heat generated by engine 100 or generator 60. It is possible to prevent the heated fuel or the semiconductor components built in the control unit 30 from overheating.

As shown in this figure, a partition plate 21 and a fuel tank 80 are disposed on the cross section AA ′, and a battery 32, a space heater 34, and a blower fan 35 are disposed on the partition plate 21. . Here, the blower fan 35 forcibly blows the warm air in the regions 22 and 23 to the region 24 in summer, for example, thereby lowering the temperature of these regions. That is, since the power generation device 10 has a heat insulating structure, it is not easily affected by the outside, but once the heat is transmitted to the inside, it is difficult to release the heat to the outside. This makes it easier to release heat to the outside.

  FIG. 18 is a diagram illustrating the flow of air inside the ducts 13 and 14 and the housing 11. As shown by the arrows in this figure, air flows in through the suction holes 13 c and 13 d at the top of the duct 13 or the suction hole 13 e 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 and then passes through the duct 14 and is discharged through the upper discharge holes 14c and 14d (not shown) or the lower discharge holes 14e (not shown). . The exhaust gas of the engine 100 passes through the muffler 131 and is then discharged from the exhaust pipe 17 to the outside. Further, the air accumulated in the regions 22 and 23 and the like is forcibly circulated to the region 24 by the blower fan 35.

  In the power generation device 10 according to the embodiment of the present invention, the housing 11 and the roof 12 are made of a heat insulating structure so that they are not easily affected by the outside, and the interior of the housing 11 is divided into upper and lower portions by a partition plate 21 and the like. By disposing the engine 100 and the control unit 30 and the like on the top, the control unit 30 and the like are hardly affected by the heat generated by the engine 100. Moreover, since the ventilation fan 35 is provided in the partition plate 21 and the heat accumulated in the upper part is discharged, it is possible to prevent the control unit 30 and the like from being overheated.

  Furthermore, since the outside air is introduced as needed by the dampers 140 and 150, the startability of the engine 100 can be ensured by closing the dampers 140 and 150 in winter and the like.

  FIG. 19 is a diagram showing the connection relationship of the fuel system. As shown in this figure, the external fuel tank 200 is disposed outside the housing 11, and the fuel 201 is stored inside. At the upper part of the fuel tank 200, a supply port 202 for supplying fuel and a connecting portion 203 to which a fuel pipe 250 for returning the fuel from the power generation apparatus 10 is connected are provided. A fuel pipe 251 is connected to the bottom surface of the fuel tank 200, and a connection part 204 for supplying fuel to the power generation apparatus 10 is provided. The upper left portion of the fuel tank 200 has a full oil warning device 253 that issues a warning when fuel is about to overflow. An oil return pump 252 for returning the fuel discharged from the outlet portion 18b to the fuel pump 200 is provided in the middle of the fuel pipe 250. The engine 100 has a fuel injection pump for injecting fuel into the cylinder, and the pump is configured to recirculate part of the supplied fuel, so that the fuel tank 80 or the fuel tank A mechanism for returning the fuel to 200 is required.

  The inlet portion 18a of the power generation apparatus 10 is connected to one of the connecting portions of the branch pipe 18e by a fuel pipe 18c. One of the other connecting portions of the branch pipe 18e is connected to the input portion of the fuel filter 18f by the fuel pipe 18g, and the other connecting portion of the branch pipe 18e is connected to a connecting portion 86 provided on the bottom surface of the fuel tank 80. The connected check valve 87 is connected by a fuel pipe 18h. Here, the check valve 87 prevents the fuel from flowing back from the fuel tank 200 to the fuel tank 80 when the liquid level of the fuel tank 200 is higher than that of the fuel tank 80. The output part of the fuel filter 18f is connected to the input part 102 of the engine 100 by a fuel pipe 18j. The fuel returning from the fuel filter 18f is input to one of the connecting portions of the branch pipe 18k through the fuel pipe 18i. One of the other connecting parts of the branch pipe 18k is connected to a recirculation part 101 for recirculating the fuel of the engine 100 by a fuel pipe 18n. Still another connecting portion of the branch pipe 18k is connected to a connecting portion 84 provided on the bottom surface of the fuel tank 80 by a fuel pipe 18m.

  The fuel tank 200 is installed at a position higher than the fuel tank 80, and the liquid level of the fuel tank 200 is often higher than the liquid level of the fuel tank 80. In this case, the engine 100 includes the fuel tank 200. The fuel is supplied from. At this time, since the pressure of the fuel from the fuel tank 200 is higher than the pressure of the fuel from the fuel tank 80, the check valve 87 operates to prevent the fuel from flowing back from the fuel tank 200 to the fuel tank 80. The On the other hand, the fuel returning from the fuel filter 18f and the engine 100 is collected by the fuel pipe 18m via the branch pipe 18k, and returned to the inside of the fuel tank 80 via the connecting portion 84 and the pipe 85 of the fuel tank 80. If the fuel tank 80 is filled with the recirculated fuel, excess fuel is discharged through the fuel pipe 18d and returned to the fuel tank 200 by the oil return pump 252, so that the fuel tank 80 Can prevent fuel from overflowing. Further, since the fuel tank 200 is provided with the oil full warning device 253, the fuel tank 200 can be prevented from overflowing.

  FIG. 20 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 temperature detection sensor 31, a heater 10b, a damper opening / closing motor 10c, a power failure detection sensor 10d, a control unit 30, a blower fan 35, a switch 10e, an AVR (Auto Voltage Regulator) 30b, Machine 60 and engine 100.

  Here, the temperature detection sensor 31 detects the regions 22 to 24 or the outside air temperature, and notifies the control unit 30 of them. The heater 10 b includes space heaters 33, 34, 61 and an infrared heater 121. The damper opening / closing motor 10c has motors 140a and 150b.

  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.

  The control unit 30 includes an operation unit 30a. 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. The number of revolutions of engine 100 is controlled so that power of a predetermined voltage and frequency is output from machine 60. 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.

  The blower fan 35 has a function of forcibly circulating the heat accumulated in the upper part of the housing 11 to the lower part.

  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 control unit 30 refers to the output of the temperature detection sensor 31, and when the internal temperature of the housing 11 becomes equal to or lower than a predetermined temperature, the controller 10 energizes the heater 10b, and the internal temperature is, for example, −5 ° C. or lower. Control so that it does not become. Moreover, the control part 30 melt | dissolves the freezing of the blade | wing 140d-140g of the damper 140 by supplying with electricity to the infrared heater 121, and makes it easy to open and close. Thus, engine 100 can be started smoothly even when the outside air temperature is below freezing. Moreover, since the electric power generating apparatus 10 which concerns on embodiment of this invention has a heat insulation structure as mentioned above, the inside of the housing | casing 11 can be warmed with little electric power.

  When the controller 30 detects the occurrence of a power failure by the power failure detection sensor 10d, the engine 100 is started by supplying DC power from the battery 32 to a cell motor (not shown). When the engine 100 is started and a predetermined time elapses, the control unit 30 supplies electric power from the generator 60 to the damper opening / closing motor 10c to open the dampers 140 and 150.

  When engine 100 is started, control unit 30 controls the rotational speed of engine 100 so that the output of generator 60 has a predetermined frequency and a predetermined voltage. When the output is stabilized, the control unit 30 switches the switch 10e to the generator 60 side. As a result, since the electric power generated by the generator 60 is supplied to the electric equipment 2, the electric equipment 2 can continue its operation.

  When the cancellation of the power failure is detected by the power failure detection sensor 10d, the control unit 30 first switches the switch 10e to the commercial power source 1 side. As a result, power from the commercial power source 1 is supplied to the electrical equipment 2. Subsequently, the control unit 30 stops the engine 100 and controls the damper opening / closing motor 10c to close the dampers 140 and 150. As a result, since the housing 11 is cut off from the outside, the inside of the housing 11 can be kept at a predetermined temperature with a small amount of power even when the outside air temperature is low. The dampers 140 and 150 may be opened until the engine 100 is cooled to a predetermined temperature.

  When the temperature detection sensor 31 detects that the temperature of the upper part of the housing 11 is higher than a predetermined temperature, the control unit 30 drives the blower fan 35 and heat accumulated in the upper part. Is forcibly circulated in the lower part to prevent the controller 30 and the fuel tank 80 from being overheated. At the same time, the dampers 140 and 150 are opened, and heat is discharged to the outside by the electric fan 110a (fan for the radiator 110).

  As described above, in the power generation device 10 according to the embodiment of the present invention, since the casing 11 and the roof 12 have a heat insulating structure, the internal temperature can be kept constant regardless of changes in the external temperature. it can. For this reason, the startability of the engine 100 can be improved, and the inside of the housing 11 can be kept at an optimum temperature with a small amount of electric power.

  Further, in the above embodiment, the inside of the housing 11 is divided into the upper part and the lower part by the partition plate 21 or the like, the engine 100 or the like is arranged at the lower part, and the engine 100 is supplied by the air introduced through the dampers 140 and 150. Therefore, the engine 100, which is a heat source, can be appropriately cooled, and the controller 30 and the fuel tank 80 can be prevented from being overheated.

  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 two doors 15 and 16 are provided, but only one door may be provided. Further, the doors 15 and 16 may be filled with a heat insulating member to enhance the heat insulating property.

  In the above embodiment, one blower fan 35 is provided on the partition plate 21, but one blower fan is provided for each partition plate, or a plurality of blower fans are provided on each partition plate. It may be provided.

  Further, in the above embodiment, the dampers 140 and 150 are in either the open state or the closed state. However, the dampers 140 and 150 are opened according to the temperature in the housing 11. The degree may be adjusted. Specifically, the opening degree may be increased when the temperature in the housing 11 is high, and the opening degree may be decreased when the temperature is low. According to such an embodiment, by adjusting the temperature in the housing 11, the startability of the engine 100 can be enhanced, overheating and the like can be prevented, and the durability of the engine 100 can be enhanced. .

  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. However, other arrangements may be used.

  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.
