And while the rotating shaft 34 is arrange | positioned in the recess 32, the axial direction of the rotating shaft 34 is substantially parallel to the longitudinal direction L. As shown in FIG.

The main body 33 has four rectangular side surfaces and two substantially square end surfaces. The rotating shaft 34 is inserted into the main body 33 such that the axial center of the rotating shaft 34 is located at the intersection of diagonals of the end faces of the main body 33. Therefore, each side surface of the main body portion 33 faces outward in the direction perpendicular to the rotation shaft 34, and the longitudinal direction of each side surface is substantially parallel to the axial direction of the rotation shaft 34. Therefore, by rotating the main body 33 around the rotation axis 34, the direction of each side surface is changed.

Further, the main body 33 has a connecting portion 35 connected to the external load device 60 to supply the electric power generated by the power generation unit 12 on a first side surface which is one of the side surfaces. In the example of FIG. 1, the output unit 14 has three connection units 35. Each connecting portion 35 is, for example, a connector or a jack for connecting to an end portion 61 (for example, a plug) of an external load device 60 (corresponding to the external load in FIG. 2) such as a power cord of a power tool It becomes a mouth etc. And the main-body part 33 has a conducting-wire member (not shown) electrically connected with the load apparatus 60 in an inside.

That is, the housing 2 holds the output portion 14 so that the direction of the connection surface of the connection portion 35 can be switched to the direction of the base portion 3 or the direction of the first side portion 6.

Therefore, the connection portion 35 of the main body portion 33 holds the end portion 61 of the load device 60 and is electrically connected to the held end portion 61 by the conductive member. The electric power generated by the power generation unit 12 is adjusted by the adjustment unit 13 and then supplied to the load device 60 through the output unit 14. The number of sides is not limited to four, and may be three or five or more.

Further, as shown in FIG. 2, the power generation unit 12 further includes a reflux unit 31 configured to return water generated by the fuel cell unit 28 and water remaining in the fuel cell unit 28 after power generation to the water tank 25. Prepare. Then, by returning the water in the fuel cell unit 28 to the water tank 25 via the reflux unit 31, consumption of water in the water tank 25 can be easily suppressed, and the capacity of the water tank 25 can be reduced (small and light). It will be easier.

In addition, as shown in FIG. 3, the housing 2 further includes an air supply unit and an exhaust unit that allow the inside of the case 26 of the power generation unit 12 to communicate with the outside of the housing 2. Outside air flows in, and the air in the housing 2 is exhausted from the exhaust unit to the outside.

The air supply unit includes an air supply port 36 opened in the side portion 7, an air supply flow path 37 connecting the air supply port 36 and the air supply opening of the case 26, and air disposed at the upstream end of the air supply flow path 37. And a filter 38. Then, air (outside air) is flowed into the inside of the air supply unit by the drive of the air pump 30, and the outside air flows from the air supply port 36 to the air supply opening via the air supply flow path 37. Further, the foreign material mixed into the outside air and introduced into the air supply port 36 is blocked by the air filter 38 from flowing to the downstream side of the air supply flow path 37, and hardly enters the power generation unit 12.

The exhaust unit includes an exhaust port 39 opened at the side portion 8, an exhaust flow path 40 connecting the exhaust port 39 and the exhaust opening of the case 26, and an air filter 41 disposed at the downstream end of the exhaust flow path 40. Prepare. Then, exhaust gas generated by the power generation unit 12 such as carbon dioxide flows into the inside, and the exhaust gas flows from the exhaust opening to the exhaust port 39 through the exhaust flow passage 40 and is discharged to the outside of the housing 2 Ru. In addition, foreign matter mixed in with the wind from the outside of the housing 2 is blocked by the air filter 41 from flowing into the exhaust flow path 40, and a strong air is blown when the exhaust unit is not performing the exhaust operation or outside the housing 2 Foreign matter is less likely to infiltrate into the power generation unit 12 also at the time of occasion.

The trolley mechanism unit 9 includes wheels 42 and is configured to allow a person to push or pull by the power generator 1 having the trolley mechanism unit 9. Desirably, the trolley mechanism 9 includes an axle 43 held by the housing 2 and at least two wheels 42 configured to rotate about the axle 43. In the example shown in FIG. 3, the trolley mechanism unit 9 holds the axle 43 along the longitudinal direction L, the disc-shaped wheels 42 respectively provided at the end of the axle 43, and the axle 43 in the housing 2. And a holder (not shown) for

Axle 43, as shown in FIG. 1, is held in the holding section located in the second end 3 ₂ side of the base portion 3 (see FIG. 4) is parallel to the longitudinal direction L. Then, as shown in FIG. 3, one end of the axle 43 projects from the side 7 and the other projects from the side 8. Both ends of the axle 43 are mounted at the centers of the two wheels 42 respectively.

The radius of the wheel 42 is larger than the dimension from the center of the wheel 42 (circle) to the second end 3 ₂ (rear end) of the base 3 as shown in FIG. 4. The outer periphery of the wheel 42 protrudes rearward and downward from the housing 2 in a side view, and the wheel 42 can support the housing 2 on a floor surface (not shown) or the like of the structure.

Then, the casing 2 can be easily moved forward or backward by bringing the rotatable wheel 42 into contact with the floor surface of the structure and rolling it. In addition, by rotating the housing 2 around the axis of the wheel 42, the orientation of the housing 2 (the posture of the power generation device 1) with respect to the floor surface can be changed. The power generation apparatus 1 has a first orientation in which the surface of the base portion 3 faces the floor and a second orientation in which the surface of the first side portion (rear wall portion) 6 as shown in FIG. 5 faces the floor. The posture of the power generation device 1 can be switched by selecting any of the above.

Further, as shown in FIG. 4, the base portion 3 further includes a first leg portion 44 for supporting the housing 2 together with the wheel 42 in the first position, in addition to the trolley mechanism portion 9. As shown in FIGS. 1 and 4, the housing 2 has two first leg 44 which is provided on both sides of the first end 3 ₁ side of the base portion 3. As another example, the housing 2 may have a single first leg of which is provided at the center of the first end 3 ₁ side of the base portion 3. The first leg may be disposed between the center between the first and second ends of the first end 3 ₁ and the base portion 3 of the base portion 3 (3 ₁ and 3 _2). In short, the first leg of the present invention is provided in the first end 3 ₁ side of the base portion 3.

In the example of FIG. 4, the first leg 44 protrudes downward and is provided on the first end 3 ₁ (front end) side of the base 3, and abuts on the floor surface in the first posture. Therefore, the housing 2 can be supported on the floor by the first leg 44 and the wheel 42 by bringing the first leg 44 into contact with the floor. Then, the power generation device 1 is movable in a transportable posture by tilting the housing 2 backward (tilting backward) with the axle 43 as a fulcrum from the first posture and separating the first leg portion 44 from the floor surface. , And can be transported via the trolley mechanism 9.

The housing 2 has one of the second leg portion 45 which is provided in the second end 6 ₂ side of the first side 6. More specifically, in addition to the second leg 45 supporting the housing 2 together with the wheel 42 in the second posture, the side 6 has a movement operation unit 46 used during transportation. As shown in FIG. 1, the second leg portion 45 is disposed in the center of the second end 6 ₂ side of the first side. As another example, the housing 2 may have two second leg portions being provided on both sides of the second end 6 ₂ side of the first side. The second leg is between the center between the (first) second end 6 ₂ (first) side 6 the first and second end (6 ₁ and 6 ₂₎ of the side 6 It may be arranged. In short, second leg of the present invention is provided in the second end 6 ₂ side portion 6.

In the example of FIG. 4, and a moving operation part 46, the two rod-shaped portion 47 projecting upward from the second end 6 ₂ side portion 6, the bridge portion 48 connecting the upper end of the rod portion 47 . The upward projecting amount of the rod-like portion 47 is adjustable. The outer surface of the bridge portion 48 is a gripping surface to be gripped by the user.

Therefore, when the power generation device 1 is switched to the transport posture, the movement operation unit 46 can be gripped to change the posture of the housing 2, and the posture of the power generation device 1 can be easily switched. Then, the housing 2 can be pulled through the movement operation unit 46 to allow the wheels 42 to travel, and the housing 2 can be easily moved. In addition, by adjusting the amount of protrusion of the rod-like portion 47 to be small, it is possible to make the movement operation unit 46 less likely to interfere with the use of the power generation device 1 at times other than transportation such as use as an external power supply.

In the example of FIG. 4, the second leg 45 protrudes from the second end 6 ₂ side portion 6 backwards. The second leg 45 is in contact with the floor surface in the second posture, as shown in FIG. Therefore, the housing 2 can be supported on the floor by the second leg 45 and the wheel 42 by bringing the second leg 45 into contact with the floor. Further, the power generation device 1 is brought into the transport posture by lifting the top 4 side of the housing 2 upward with the axle 43 as a fulcrum from the second posture and separating the second leg 45 from the floor surface. Therefore, the main transport posture is an intermediate posture that occurs when switching between the first posture and the second posture.

The side portion 8 further includes a power generation operation unit such as a power switch 49 for turning on / off the power generation operation of the power generation unit 12. Therefore, in the power generation device 1, the power generation unit 12 starts the power generation operation by turning on the power switch 49, and the power generation operation is stopped by turning off the power switch 49 during the power generation operation. After the entering operation, the power generation operation is continued until the turning-off operation is performed.

The trolley mechanism 9 that is provided on the second end 3 ₂ (rear end) of the base portion 3, the posture change of the housing 2 is restricted in the rotational direction of the wheel 42. The outer surface of the base portion 3 and the outer surface of the side portion 6 are surfaces on the ground side of the housing 2, and an axle 43 is provided at a corner between them, and a wheel 42 protrudes from the corner. Therefore, the power generation device 1 can take a first posture in which the outer surface of the base portion 3 is the lower surface or a second posture in which the outer surface of the side portion 6 is the lower surface.

In the example of FIG. 4, the output unit 14 is provided at the upper end of the side portion 5. As a result, the output unit 14 is less likely to be blocked by the floor surface or the like at the first and second postures or the moving posture, and the load device 60 can be easily connected to the output unit 14. Then, the main body 33 of the output unit 14 is made rotatable with respect to the housing 2, and the rotary shaft 34 is made substantially parallel to the axle 43 to rotate the main body 33, thereby connecting the connection portion 35. The orientation of the surface can be switched to the orientation on the base 3 side or the orientation on the side 6 side. Therefore, the connection surface of the connection portion 35 can be directed obliquely downward in any of the first and second postures shown in FIGS. 4 and 5 at the time of outdoor use in rainy weather or the like. As a result, it is possible to make rainwater hard to hit the connection surface of the connection portion 35, and it becomes easy to avoid operation failure such as leakage due to rain water.

Further, the liquid storage portion 11 is positioned above and to the rear of the power generation portion 12 when changing to the second position by disposing the liquid storage portion 11 above and forward of the power generation portion 12 based on the first position. At the time of the change to the rearwardly inclined movement posture, the liquid storage portion 11 is positioned above the power generation portion 12. Therefore, the liquid fuel can be supplied from the liquid storage unit 11 to the power generation unit 12 by its own weight (gravity) of liquid fuel, and the liquid fuel supply to the power generation unit 12 can be performed with a simple configuration. Furthermore, since it is possible to abolish the fuel drawing-in device that sucks the liquid fuel from the liquid storage portion 11 and to reduce the output, it is possible to reduce the size and weight of the power generation device 1 and reduce the production cost.

Further, by providing the first inclined surface 20 and the second inclined surface 21 in the tank 15, the liquid fuel is easily introduced to the supply port 23 in the first and second postures and the movement posture, and the liquid is stabilized. Fuel can be easily supplied. And since it becomes easy to maintain the upstream opening of supply path 22 covered with liquid fuel at the time of 1st and 2nd attitude, movement attitude, or attitude change, gas such as air in tank 15 penetrates into supply path 22 This can make it difficult to prevent the occurrence of malfunction due to gas mixing into the flow path on the liquid fuel side. Furthermore, by providing the inlet 27 of the power generation unit 12 at the front end of the upper surface of the case 26, it is difficult for the liquid fuel in the power generation unit 12 to backflow to the inlet 27 when changing the first and second postures or the movement posture or posture. Become.

In addition, an outer wall portion (side wall portion) which is not easily blocked in any of the first and second postures is defined, and by providing the exhaust port 39 and the air supply port 36 in the relevant portion, malfunction due to blockage of the exhaust port 39 or the like It is possible to easily suppress the occurrence of malfunction and the like. Further, by providing the power generation operation portion on the side portion 8, it becomes difficult to contact at the time of transportation as compared with those provided on the side portion (front wall portion) 5 and the side portion 6. It becomes difficult to be closed at the time of the 1st and 2nd posture compared with what was provided.

In the example of FIG. 4, the output portion 14 is not limited to the front end of the top portion 4, and may be provided above the lower end of the side portion 5 or in front of the rear end of the top portion 4.
