Description

[Technical Field]

[0001] The present invention relates to a trailer house. [Background technology]

[0002] Patent Document 1 discloses a plurality of towed vehicles each having a solar power generation device, a power storage device, and a charge / discharge control unit. The charge / discharge control unit controls the charging and discharging of the power storage devices between the plurality of towed vehicles based on a charge control method that supplies power to the power storage devices provided in each of the towed vehicles whose charge rates are equal to or higher than a predetermined threshold.

[0003] Patent Documents 2 and 3 disclose trailer houses equipped with solar power generation systems. According to Patent Document 2, the solar power generation system is installed on the roof of the trailer house, so it is small and its output power is not very high. Therefore, the solar power generation system cannot provide all of the electricity needed for living in the trailer house. Therefore, it is possible to install other power generation systems in addition to the solar power generation system on the trailer house, and hydrogen fuel cells are a promising example of such a power generation system. Hydrogen fuel cells require hydrogen to generate electricity, and hydrogen containers must be stored in the trailer house, which also requires management and maintenance. When the hydrogen container is empty, the filled hydrogen container must be replaced with an empty one. The applicant's prior art search did not reveal any documents disclosing trailer houses equipped with hydrogen fuel cells. Therefore, the applicant does not recognize such trailer houses as publicly known technology. [Prior art documents] [Patent documents]

The trailer house (1) is Cart (2) and a house (10) mounted on the carriage (2); a door (25) provided on the outer wall (12) of the house (10); a shelf (30) disposed inside the house (10) and close to the outer wall (12); The shelf (30) Shelves (37) and partitions (39) arranged in a lattice pattern; a plurality of storage cells (40) for storing hydrogen containers, which are separated by the shelves (37) and the partition plates (39) and arranged in a grid pattern; and The plurality of storage cells (40) are arranged inside the house (10) in front of the door (25), and the plurality of storage cells (40) are open toward the door (25) and in the opposite direction to the door (25). 、 The ceiling inside the house (10) is a sloped ceiling, and the exhaust port is formed at the top end of the wall located higher on the sloped ceiling among the surrounding walls of the house (10). .

[0008] According to claim 1 as described above, the shelf (30) is disposed inside the house (10) close to the exterior wall (12), the door (25) is attached to the exterior wall (12), and the storage cell (40) is disposed inside the house (10) in front of the door (25). Therefore, by opening the door (25), the hydrogen container (90) in the storage cell (40) can be easily reached from outside the house (10). Therefore, the hydrogen container (90) can be easily managed, maintained, replaced, removed, or taken in from outside the house (10). Even if hydrogen leaks from the hydrogen container (90), the hydrogen can be released outside the house (10) by opening the door (25). Since the storage cell 40 opens in the direction opposite to the door 25, the hydrogen container 90 in the storage cell 40 is readily accessible from inside the house 10. This allows for easy handling, such as management, maintenance, replacement, storage, removal or introduction, of the hydrogen container 90 from inside the house 10. Since the shelf (30) is disposed inside the house (10) and close to the outer wall (12), the space inside the house (10) can be effectively used for storing the hydrogen containers (90). By storing a plurality of hydrogen containers (90) in a plurality of storage cells (40), even if one of the hydrogen containers (90) becomes empty, the other hydrogen containers (90) can supply hydrogen. Because the storage cell 40 opens in the direction opposite to the door 25, even if hydrogen leaks from the hydrogen container 90, the hydrogen rises from the storage cell 40 toward the ceiling 17. Because the ceiling 17 is sloped, the hydrogen that rises to the ceiling 17 flows toward the higher part of the sloped ceiling and is released outside the house 10 through the exhaust port 15a. Therefore, even if hydrogen leaks, the safety inside the house 10 is ensured.

The left and right wheels 4 are attached to the left and right sides of the base 3, respectively, and the base 3 is supported on the installation surface 99 by the wheels 4. The base 3 is supported on the ground of the site by a support base. The support base can be easily removed from the bogie 2 without tools. The bogie 2 has a coupler 5 attached to the front end of the base 3, and the bogie 2 can be connected to a towing vehicle by the coupler.

[0028] The house 10 is placed on a platform 3 of the cart 2. The house 10 may have a wall structure, a frame structure, or both. The house 10 may be a wooden house or a light steel frame house. The house 10 may be constructed using a panel construction method, a frame construction method, a frame panel construction method, a frame wall construction method, or a combination of two or more of these. In one example, the house 10 is a wooden house with a wall structure assembled using a wood panel adhesive construction method. In another example, the house 10 is a light steel frame house with a frame structure assembled using a prefabricated construction method. In another example, the house 10 is a wooden house with a frame structure assembled using a frame construction method.

[0029] The house 10 has a storage or living space inside. The house 10 has a floor 11 at its bottom, a rear wall 12 and a false wall 20 at its rear, a front wall 13 at its front, side walls 14 and 15 at its left and right sides, and a roof 16 at its top. For example, if the house 10 is a wooden house assembled using a wood panel adhesive construction method, the floor 11, rear wall 12, side walls 14 and 15, front wall 13, and roof 16 are made of architectural wood panels. A architectural wood panel includes a rectangular frame formed by assembling four wooden frames into a rectangular frame shape and wooden facings attached to one or both sides of the rectangular frame. A architectural wood panel may also include one or more wooden crosspieces attached to the rectangular frame. A architectural wood panel may also include an insulating material, such as glass wool, rock wool, or foamed resin, filled inside the rectangular frame.

[0030] The floor 11 is laid on the frame 3. The rear wall 12 is erected at the rear end of the floor 11, and the lower end of the rear wall 12 is joined to the rear end of the floor 11. The side walls 14 and 15 are erected at the left and right ends of the floor 11, and the lower ends of the side walls 14 and 15 are joined to the left and right ends of the floor 11, respectively. The front wall 13 is erected at the front end of the floor 11, and the lower end of the front wall 13 is joined to the front end of the floor. The front wall 13 is joined to the front ends of the side walls 14 and 15, and the rear wall 12 is joined to the rear ends of the side walls 14 and 15. These walls 12 to 15 are exterior walls that separate the interior space of the house 10 from the outdoors. The combination of these walls 12 to 15 is called the perimeter wall of the house 10. The roof 16 covers the interior space of the house 10, and the outer periphery of the roof 16 is joined to the upper ends of the rear wall 12, the side walls 14 and 15, and the front wall 13. The roof 16 is a single-pitch roof that slopes downward from the side wall 15 to the side wall 14. Therefore, the ceiling 17 inside the house 10 is a sloped ceiling that slopes downward from the side wall 15 to the side wall 14.

[0031] Side wall 15 is located at the higher end of the sloped ceiling and has exhaust port 15a at its upper end. Exhaust fan 15b is provided at exhaust port 15a. Exhaust fan 15b sends out air from inside house 10 through exhaust port 15a. Exhaust fan 15b does not necessarily have to be provided at exhaust port 15a. Hydrogen sensor 15c may be provided inside house 10 near exhaust port 15a.

[0032] Entrance doors 18, 19 are provided on the outer walls of the house 10. Specifically, door 18 is provided on side wall 14 of the house 10, and door 19 is provided on side wall 15 of the house 10. More specifically, openings are formed in the centers of the side walls 14, 15, respectively, and doors 18, 19 are attached to the openings in the side walls 14, 15. Doors 18, 19 are outward-swinging doors. The type of doors 18, 19 is not limited to hinged doors, and may be, for example, sliding doors.

[0033] A door 25 for loading and unloading the hydrogen container 90 is provided on the outer wall of the house 10. Specifically, the door 25 is provided on the rear wall 12 of the house 10. More specifically, an opening 26 is formed in the lower center of the rear wall 12, and the door 25 is attached to the opening 26. The height of the door 25 is lower than the height of the rear wall 12. The door 25 is an outward-opening door. The position of the lower end of the door 25 is aligned with the height of the floor 11 of the house 10, and when the door 25 is opened, the upper surface of the floor 11 faces the outdoors. The door 25 has a door frame 27, a door body 28, and hinges 29. The door frame 27 is assembled into a rectangular frame shape. The door frame 27 is attached to the edge of the opening 26 along the edge of the opening 26. The upper end of the door sill of the door frame 27 may be flush with the upper surface of the floor 11, or may be lower than the upper surface of the floor 11. The hinge 29 is attached to one of the vertical frames of the door frame 27, and the door body 28 is connected to the vertical frame of the door frame 27 by the hinge 29.

[0034] The natural energy power generation device 70 is installed on the roof 16. The natural energy power generation device 70 generates power from natural energy. For example, the natural energy power generation device 70 has a solar power generation panel that generates power from solar energy. The natural energy power generation device 70 may have a wind turbine that generates power from wind energy instead of or in addition to the solar power generation panel. Note that the natural energy power generation device 70 may be installed on the side wall 14 or the side wall 15.

[0035] Inside the house 10, a false wall 20 is provided on the inner surface of the rear wall 12. The false wall 20 is provided on the inner surface of the rear wall 12 in an area above an opening 26 in the rear wall 12 so as not to block the door 25. The false wall 20 has a cavity therein. For example, a plurality of studs are attached to the inner surface of the rear wall 12, and a panel is attached to these studs, forming a cavity between the panel and the inner surface of the rear wall 12. The cavity is used as a space for wiring or piping, or both.

[0036] The power conditioner 60, distribution boards 61 and 62, and switchboard 63 are attached to the false wall 20. The power conditioner 60 is connected to a natural energy power generation device 70, and the power generated by the natural energy power generation device 70 is output to the power conditioner 60. Electrical wires from the natural energy power generation device 70 to the power conditioner 60 may pass through a cavity inside the false wall 20. If a second natural energy power generation device such as a solar power generation panel is installed on the roof of the second trailer house, the power conditioner 60 is connected to the second natural energy power generation device, and the power generated by the second natural energy power generation device is output to the power conditioner 60. Electrical wires from the second natural energy power generation device to the power conditioner 60 may pass through a cavity inside the false wall 20.

[0037] The power conditioner 60 adjusts the power generated by the natural energy power generation device 70, and also adjusts the power generated by the second natural energy power generation device as needed. Adjustment refers to, for example, DC / AC conversion, voltage transformation, or both. The power adjusted by the power conditioner 60 is output to the power controller 64. The electric wires from the power conditioner 60 to the power controller 64 may be routed through the cavity inside the false wall 20.

[0038] The shelf 30 is arranged on the floor 11 inside the house 10, close to the rear wall 12. The shelf 30 is arranged under the false wall 20. The shelf 30 is a shelf without a back panel. The shelf 30 protrudes from the space under the false wall 20 towards the front wall 13. The shelf 30 may be placed on the floor 11 so that the shelf 30 is recessed from the space under the false wall 20. The shelf 30 may be fixed to at least one of the floor 11, the rear wall 12, or the side walls 14, 15.

[0039] The shelf 30 includes a top plate 31 , side plates 32 and 33 , a bottom plate 34 , partition plates 35 and 36 , a plurality of shelf plates 37 , and a plurality of partition plates 39 .

[0040] The side plates 32, 33 are joined to the left and right ends of the bottom plate 34 and the top plate 31 and are erected, and the top plate 31, side plates 32, 33, and bottom plate 34 are assembled into a rectangular frame shape. The top plate 31, side plates 32, 33, and bottom plate 34 are close to the rear wall 12 and abut against the inner surface of the rear wall 12. The top plate 31, side plates 32, 33, and bottom plate 34 may be joined to the rear wall 12 or may be separated from the rear wall 12. The side plates 32, 33 are in surface contact with the inner surfaces of the side walls 14, 15, respectively. The side plates 32, 33 may be joined to the side walls 14, 15, respectively, or may be separated from the side walls 14, 15, respectively. The bottom plate 34 rests on the floor 11 and is in surface contact with the floor 11. The top plate 31 is abutted against the lower end of the raised wall 20. The top plate 31 may close the cavity inside the false wall 20 from below.

[0041] It is also possible that the side panels 32, 33 are not provided, and the side walls 14, 15 form the side panels of the shelf 30. In this case, the top panel 31 is bridged between the side walls 14 and 15, and both ends of the top panel 31 are joined to the side walls 14, 15. It is also possible that the bottom panel 34 is not provided, and the floor 11 forms the bottom panel of the shelf 30.

[0042] The partition plates 35, 36 are joined to the bottom plate 34 and the top plate 31 and stand between the side plates 32, 33. The partition plates 35, 36 are spaced apart, and the area between the partition plates 35, 36 is directly in front of the door 25. The partition plates 35, 36 are arranged along the side edges of the opening 26, and the top plate 31 is arranged along the upper edge of the opening 26.

[0043] The shelves 37 and partition plates 39 are arranged in a grid pattern in the area surrounded by the top plate 31, bottom plate 34, and partition plates 35, 36. The area surrounded by the bottom plate 34 and partition plates 35, 36 is divided by the shelves 37 and partition plates 39 into a plurality of storage cells 40 arranged in a grid pattern. One hydrogen container 90 is stored horizontally in each storage cell 40. These storage cells 40 open toward the door 25. Therefore, when the door 25 is opened, the hydrogen container 90 can be taken out, put in, and handled from outside. These storage cells 40 open toward the inside of the house 10. Therefore, the hydrogen container 90 can be taken out, put in, and handled from inside the house 10. The shelf 30 may have a stopper 37a. The stopper 37a is installed on the edge of the shelf 37. The edge on which the stopper 37a is installed is the edge opposite the door 25. The hydrogen container 90 hits the stopper 37a, preventing the hydrogen container 90 from falling off the shelf 37.

[0044] Because the storage cell 40 is open toward the inside of the house 10, more specifically, in the direction opposite the door 25, even if hydrogen leaks from the hydrogen container 90, the hydrogen will rise from the storage cell 40 toward the ceiling 17. Because the ceiling 17 is sloped, the hydrogen that rises to the ceiling 17 flows toward the side wall 15. Because the exhaust port 15a is formed at the upper end of the side wall 15, the hydrogen is released to the outside of the house 10 through the exhaust port 15a. When hydrogen leaks from the hydrogen container 90 and is detected by the hydrogen sensor 15c, an alarm connected to the hydrogen sensor 15c may issue an alarm using sound, light, or video. The hydrogen sensor 15c may be built into the alarm, and the alarm may be installed near the exhaust port 15a inside the house 10. The alarm may be installed remotely from the hydrogen sensor 15c, and the output signal of the hydrogen sensor 15c may be transferred to the alarm via wiring or a communication device.

[0045] The hydrogen container 90 is cylindrical, with hemispherical bottom and top. The hydrogen container 90 stores high-pressure hydrogen. The hydrogen container 90 has a nozzle 91 at its top. The nozzle 91 has, for example, a valve, a coupler, etc. The hydrogen container 90 has a sensor 92 that measures the state of the hydrogen container 90. For example, the sensor 92 is a remaining amount sensor that measures the remaining amount of hydrogen in the hydrogen container 90. The remaining amount measurement principle of the remaining amount sensor is not important. For example, the remaining amount sensor may measure the remaining amount of hydrogen based on the pressure of hydrogen in the hydrogen container 90. The remaining amount sensor may measure the remaining amount of hydrogen based on the distortion of the hydrogen container 90. The remaining amount sensor may measure the remaining amount of hydrogen based on the total weight of the hydrogen container 90 and the hydrogen inside it.

[0046] The fuel cell power generation module 50 is housed in a shelf 30. Specifically, the fuel cell power generation module 50 is placed on a base 51 and housed in an area surrounded by a top plate 31, side plates 32, a bottom plate 34, and a partition plate 35. The fuel cell power generation module 50 has a fuel cell stack, auxiliary equipment, a housing, etc. The auxiliary equipment includes, for example, air supply system fluid equipment, hydrogen supply system fluid equipment, thermal equipment (for example, a heat exchanger, heat recovery unit, or radiator), sensors, piping, wiring, etc. The fuel cell stack and auxiliary equipment are housed in a housing.

[0047] A plurality of hydrogen supply pipes 52 are connected to the hydrogen supply system fluid device of the fuel cell power generation module 50. The hydrogen supply pipes 52 are routed from the fuel cell power generation module 50 through the partition plate 35 to the storage cell 40. The hydrogen supply pipes 52 may be routed from the fuel cell power generation module 50 to the storage cell 40 via a cavity inside the wall 20. The hydrogen supply pipes 52 are detachable from the nozzle 91 of the hydrogen container 90. When the hydrogen supply pipe 52 is connected to the nozzle 91 of the hydrogen container 90, hydrogen is supplied from the hydrogen container 90 to the fuel cell power generation module 50 by the hydrogen supply system fluid device. Air is taken into the fuel cell power generation module 50 by the air supply system fluid device. The air and hydrogen are sent to the fuel cell stack of the fuel cell power generation module 50, and the oxygen in the air and the hydrogen electrochemically react in the fuel cell stack to produce by-products such as water and electricity.

[0048] The drain pipe 53 is connected to the fuel cell stack of the fuel cell power generation module 50. The drain pipe 53 passes through the rear wall 12 at a position lower than the lower end of the fuel cell power generation module 50. The generated by-products are discharged from the fuel cell stack to the outside of the house 10 through the drain pipe 53. In addition to the by-products, unreacted hydrogen may also be discharged from the fuel cell stack to the outside of the house 10 through the drain pipe 53. The drain pipe 53 may also be used as a purge pipe. The purge pipe is a pipe that discharges purge gas during purging (flowing purge gas such as an inert gas into the fuel cell stack and discharging hydrogen and other substances remaining in the fuel cell stack together with the purge gas).

[0049] The control module 55 is housed in the shelf 30. Specifically, the control module 55 is housed in an area surrounded by the top panel 31, side panels 33, bottom panel 34, and partition panel 36. The control module 55 includes a circuit board, various electronic components, wiring, a housing, etc. The electronic components are mounted on the circuit board, and the circuit board, electronic components, and wiring are housed in the housing. A signal cable is routed from the control module 55 to the fuel cell power generation module 50 through a cavity inside the false wall 20 and connected to the fuel cell power generation module 50. A control signal is transmitted from the control module 55 to the fuel cell power generation module 50 via the signal cable, and the control module 55 controls the fuel cell power generation module 50, thereby operating the fuel cell power generation module 50. Measurement values ​​of sensors inside the fuel cell power generation module 50 are transmitted from the fuel cell power generation module 50 to the control module 55 via the signal cable, and the control module 55 monitors the operating status of the fuel cell power generation module 50.

[0050] A plurality of wires 56 are connected to the control module 55. The wires 56 are routed from the control module 55 through the partition plate 36 to the storage cell 40. The wires 56 may also be routed from the control module 55 to the storage cell 40 via a cavity inside the wall 20. The wires 56 are detachable from the hydrogen container 90, more specifically, from the sensor 92. When the wires 56 are connected to the sensor 92, the measurement value of the sensor 92 is transferred to the control module 55 via the wires 56. The control module 55 receives a signal from the sensor 92 to recognize the remaining amount of hydrogen in the hydrogen container 90 and monitor the status of the hydrogen container 90. Note that a receiver antenna may be provided in the storage cell 40 and connected to the control module 55, and a transmitter may be provided in the hydrogen container 90 and connected to the sensor 92. In this case, the measurement value of the sensor 92 is transmitted by the transmitter, and the receiver receives the transmitted measurement value via the antenna and outputs the measurement value to the control module 55.

[0051] The power controller 64 receives power generated by the fuel cell power generation module 50. Electrical wires from the fuel cell power generation module 50 to the power controller 64 may pass through a cavity inside the false wall 20. The power controller 64 receives power generated by the renewable energy power generation device 70 through the power conditioner 60. The power controller 64 receives power generated by the second renewable energy power generation device of the second trailer house through the power conditioner 60. Electrical wires from the power conditioner 60 to the power controller 64 may pass through a cavity inside the false wall 20. If the battery is located inside the house 10, the power controller 64 is connected to the battery.

[0052] The power controller 64 includes a DC / DC converter, a DC / AC converter, an AC / DC converter, a transformer, a charge / discharge circuit, a control circuit, etc. The power controller 64 is connected to a switchboard 63, which is connected to distribution boards 61 and 62. A commercial power source may be connected to the switchboard 63.

[0053] The power controller 64 supplies the power generated by the fuel cell power generation module 50 to the distribution boards 61 and 62 via the switchboard 63. The power controller 64 supplies the power generated by the natural energy power generation device 70 to the distribution boards 61 and 62 via the switchboard 63. The power controller 64 supplies the power generated by the second natural energy power generation device to the distribution boards 61 and 62 via the switchboard 63. When surplus power is generated in the power supplied from the power controller 64 to the distribution boards 61 and 62, the power controller 64 charges the surplus power to the battery. When a power shortage occurs in the power supplied from the power controller 64 to the distribution boards 61 and 62, the power controller 64 discharges the battery and supplies the discharged power to the distribution boards 61 and 62 via the switchboard 63.

[0054] The distribution board 61 is for the house 10. A wiring network that runs throughout the house 10 is connected to the distribution board 61. The distribution board 61 distributes power to loads connected to the wiring network. The fuel cell power generation module 50 and the control module 55 are connected to the wiring network via outlets and receive power from the distribution board 61.

[0055] The distribution board 62 is for the second trailer house. A second wiring network that runs throughout the second trailer house is connected to the distribution board 62 via an electric cord. The distribution board 62 distributes power to loads connected to the second wiring network. Note that the distribution board 62 may also be provided in the second trailer house.

[0056] The switchboard 63 switches the source of power supply to the distribution boards 61 and 62 between the power controller 64 and a commercial power source.

[0057] <2. Summary> (1) The shelf 30 is disposed inside the house 10 near the rear wall 12, the door 24 is provided on the rear wall 12, and a plurality of storage cells 40 are disposed inside the house 10 in front of the door 25. By opening the door 25, the hydrogen containers 90 in the storage cells 40 can be easily reached from outside the house 10. Therefore, the hydrogen containers 90 can be easily managed, maintained, replaced, taken out, or taken in from outside the house 10.

[0058] (2) The hydrogen container 90 is stored in close proximity to the door 25. Even if hydrogen leaks from the hydrogen container 90, the hydrogen can be released outside the house 10 by opening the door 25.

[0059] (3) Because the storage cell 40 opens in the direction opposite to the door 25, the hydrogen container 90 in the storage cell 40 can be easily reached from inside the house 10. Therefore, the hydrogen container 90 can be easily managed, maintained, replaced, stored, taken out, or taken in from inside the house 10.

[0060] (4) A plurality of hydrogen containers 90 are stored in a plurality of storage cells 40, respectively. Therefore, even if one of the hydrogen containers 90 becomes empty, the other hydrogen containers 90 can supply hydrogen.

[0061] (5) In addition to the hydrogen container 90, the fuel cell power generation module 50 and the control module 55 are also stored on the shelf 30, so that the condition of the hydrogen container 90 can be checked and the hydrogen container 90 can be handled while managing or maintaining the fuel cell power generation module 50 and the control module 55.

[0062] (6) The hydrogen supply pipe 52 is routed from the fuel cell power generation module 50 to the storage cell 40. This shortens the routing path of the hydrogen supply pipe 52. In addition, once the hydrogen container 90 is stored in the storage cell 40, the hydrogen supply pipe 52 can be connected to the nozzle 91 of the hydrogen container 90. This makes it easy to replace the hydrogen container 90.

[0063] (7) The wiring 56 is routed from the control module 55 to the storage cell 40. This shortens the routing path of the wiring 56. In addition, the wiring 56 can be connected to the hydrogen container 90 immediately after the hydrogen container 90 is stored in the storage cell 40. This makes it easy to replace the hydrogen container 90.

[0064] (8) Even if a hydrogen leak occurs, the hydrogen rises to the ceiling 17. The slope of the ceiling 17 causes the hydrogen to flow toward the side wall 14, and the hydrogen is released outside the house 10 through the exhaust port 15a. Thorough safety measures have been taken to prevent hydrogen leaks.

[0065] (9) The cavity in the false wall 20 can be used as a space for wiring and piping. The space under the false wall 20 can be used to arrange the shelf 30.

[0066] (10) Wood is used as a material for the house 10. The energy used from the production to the disposal and discarding of wood is less than the energy used from the production to the disposal and discarding of metal or concrete materials. Therefore, the trailer house 1 contributes to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).

[0067] (11) The above-disclosed embodiments have been made for the purpose of illustration and example only, and are not intended to limit the scope of the present invention, which should be interpreted by the terms of the claims. [Explanation of symbols]
