Description

Technical Field

[0001] The present invention relates to a portable power supply system. In particular, it relates to a portable power supply system equipped with a solar power generation device.

Background Art

[0002] Conventionally, as a portable facility, a mobile sales vehicle that installs a store section on the loading platform of a vehicle and sells goods is known. Portable facilities such as mobile sales vehicles mainly use in-vehicle batteries as the power source for electrical equipment mounted on the loading platform of the vehicle. However, when the facility is installed in the same place for a long period of time, the vehicle used for movement becomes unnecessary. Therefore, it is desirable to separate the facility from the vehicle and install it. In this case, the in-vehicle battery cannot be used, and it becomes difficult to secure a power source in areas without electricity or disaster areas where portable facilities are particularly required. It is also conceivable to install a generator using fossil fuel in the facility instead of the in-vehicle battery, but fuel replenishment is required.

[0003] For example, when assuming the use of portable facilities in a disaster area, if the transportation network is cut off or the ground infrastructure is damaged due to a disaster, fuel replenishment cannot be performed, so facilities equipped with a generator using fossil fuel may not be able to provide necessary rescue and support.

[0004] On the other hand, as a portable facility that has high transportability and can be operated even in areas where it is difficult to secure a power source, a portable facility equipped with a power generation unit using natural energy has been proposed (for example, see Patent Document 1).

[0005] Patent Document 1 proposes a container-type portable facility that uses a container that can be transported by a truck or the like, and includes a solar panel member and a storage battery for storing the electric power generated by the solar power generation panel member. It has been reported that the container-type portable facility of Patent Document 1 can stably supply electric power to electrical equipment without performing construction work such as pulling electric wires. The container-type portable facility of Patent Document 1 is expected to be used in temporary housing, temporary stores, temporary offices, etc. during disasters and the like.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, even a container-type portable facility such as that of Patent Document 1 will fall under the category of buildings under the Building Standards Act if its floor area exceeds 10 m 2 . For this reason, when installing a portable facility, it is necessary to perform procedures based on the Building Standards Act, and it cannot be installed easily. Also, when loading a container-type portable facility onto a vehicle or the like and transporting it to the destination, if the height during travel of the vehicle or the like loaded with the portable facility exceeds 3.8 m, or if the length during travel exceeds 12.0 m, or if the width during travel exceeds 2.5 m, it will fall under the category of special vehicles under the law (Road Act and Vehicle Restriction Order). Special vehicles need to obtain special vehicle passage permission when traveling on public roads, which is time-consuming and laborious. Therefore, considering the labor and time required for transportation and installation, the container-type portable facility such as that of Patent Document 1 has to be a narrow facility. For this reason, the container-type portable facility such as that of Patent Document 1 cannot be used for applications that require a relatively large space, and there is room for improvement from the perspective of multi-purpose use.

[0008] The present invention has been made in view of such a background, and an object thereof is to provide a portable power supply system that has high transportability, can be operated even in an area where it is difficult to secure power, and can be used for multiple purposes.

Mode for Carrying Out the Invention

[0012] Hereinafter, the portable power supply system of the present invention will be described in detail. However, the description of the constituent elements described below is an example (representative example) as one embodiment of the present invention, and is not limited to these contents.

[0013] (Portable Power Supply System) FIGS. 1 to 4 are perspective views showing an example of the portable power supply system according to the present embodiment. FIG. 5 is a front view showing an example of the portable power supply system according to the present embodiment. The portable power supply system 100 of the present embodiment mainly includes a box-shaped structure 10, a photovoltaic power generation device 11, and a power supply unit 30.

[0014] The box-shaped structure 10 has a front wall 1, a rear wall 2, a bottom wall 3, and a wing roof 4 that constitutes at least a part of the top wall and side walls and is driven to open and close upward. Inside the box-shaped structure 10, there is a work space where a person can perform work. The photovoltaic power generation device 11 has a plurality of solar panels 11a provided on the wing roof. The power supply unit 30 is installed in the structure 10 and supplies the power generated by the photovoltaic power generation device 11.

[0015] According to the above configuration, since the structure 10 is configured to be transportable, it has high transportability. In the present specification, "transportable" means that the bottom wall 3 etc. of the structure 10 are not fixed to the ground, other equipment, etc. In addition, since the solar power generation device 11, which is one of the natural energy power generation devices, is provided, the power required for use can be covered without using the power transmission network of the power company (off-grid type). That is, even in areas where it is difficult to secure a power source, such as unelectrified areas and disaster-stricken areas where the power transmission network is not developed, electrical equipment can be operated, so that the system 100 can be easily operated. Also, since it is natural energy, it is possible to supply power in a clean and environmentally friendly way with less environmental impact.

[0016] Furthermore, unlike the conventional sealed container, the structure 10 of the present embodiment is provided with a wing roof 4 that can be opened and closed, so that the sides and the top of the structure 10 can be opened. As a result, as shown in FIG. 4, when storing, transporting, etc., the system 100 closes the sides and the top of the structure 10 to form a compact shape with a sealed working space similar to a conventional container, and when in use as shown in FIGS. 1 and 2, etc., the sides and the top of the structure 10 are opened to expand the working space for use. That is, the system 100 can be suitably used not only for applications suitable for a sealed working space such as a temporary housing or an office, but also for applications suitable for an open working space such as a store like an open café, a beach house, an event facility such as a sports meet or a sports festival, a shared bicycle, a rental bicycle, etc. Hereinafter, the system 100 will be described for each component that constitutes it.

[0017] <Structure 10> The structure 10 is formed in a substantially rectangular parallelepiped shape as a whole. The structure 10 mainly includes a front wall 1, a rear wall 2, a bottom wall 3, and a wing roof 4 that constitutes at least a part of the top wall and the side walls and opens and closes upward.

[0018] At the front end of the bottom wall 3 of the structure 10, a front wall 1 is erected, which has a front frame and left and right opening / closing doors that are rotatably supported by the front frame and open and close the front of the structure 10. At the rear end of the bottom wall 3 of the structure 10, a rear wall 2 is erected. With the opening / closing doors of the front wall 1 open, people can move in and out of the working space.

[0019] Between the front wall 1 and the rear wall 2, a pair of left and right wing roofs 4 are provided. Each wing roof 4 has a substantially L-shaped cross section including a ceiling surface body that constitutes the top wall of the structure 10 and a side surface body that extends substantially vertically downward from the outer edge in the width direction of the ceiling surface body and constitutes the upper part of the side wall of the structure 10. That is, each wing roof 4 constitutes at least a part of the top wall and the side wall of the structure 10 and forms an L-shaped cross section. Each wing roof 4 is driven to open and close between the closed position and the open position by a hydraulic cylinder 6 disposed substantially at the center of the upper part of the front wall 1 and the rear wall 2.

[0020] As shown in FIGS. 1 to 3, during power generation by the solar power generation device 11 and during the use of the system 100, each wing roof 4 is driven to the open position, and the sides and the upper part of the structure 10 are opened. Thereby, power can be efficiently generated by the solar power generation device 11. In addition, since the working space of the structure 10 changes from a closed space to a liberated space, it can be used more in accordance with the purpose of the user. As shown in FIG. 4, during storage, transportation, etc., each wing roof 4 is driven to the closed position, and the sides and the upper part of the structure 10 are closed. Thereby, the structure 10 becomes compact and highly robust, and has excellent storage properties. In addition, the system 100 can be efficiently transported to the destination. Also, it can be used even during the use of the system 100. Since the working space of the structure 10 becomes a closed space, it can be used in the same way as a conventional container.

[0021] Further, on both the left and right ends of the bottom wall 3 of the structure 10, the flaps 5 may be provided so as to be openable and closable. The flaps 5 are rotatably supported via a plurality of hinges with respect to the side edge portions of the bottom wall 3 of the structure 10, and constitute the lower side portions of the structure 10 in an upright state standing along the length direction of the bottom wall 3, and open the lower side portions of the structure 10 in a fallen state rotated downward from the upright state. At approximately the center of the side edge portion in the length direction of the bottom wall 3, a central column that can be set to an upright state and a fallen state may be rotatably supported via a hinge in the same manner as the flaps 5. When there is a central column, the flaps 5 are divided into front and rear with the central column as a boundary, and the front flap 5 and the rear flap 5 are each independently set to an upright state and a fallen state. As shown in FIGS. 1 and 2, the flaps 5 are normally used in an open state during work inside the structure 10 or the like. Thereby, a person can move to and from the side of the structure 10 with respect to the work space, and utilization according to the use of the system 100 becomes possible. On the other hand, as shown in FIGS. 3 and 4, the flaps 5 are normally used in a closed state during storage and transportation or the like. Thereby, the system 100 can be stored and transported compactly.

[0022] The size of the structure 10 is not particularly limited, but it is preferably about 3.1 m to 9.6 m in length, about 1.7 m to 2.4 m in width, and about 1.9 m to 2.6 m in height. If the size of the structure 10 is within the above range, it does not correspond to a special vehicle when transported by a vehicle or the like.

[0023] Note that the structure 10 of the present embodiment is not a self-propelled type structure 10, but a structure 10 that can be transported and moved by a transport means or the like. The structure 10 of the present embodiment is preferably one that reuses the container of a wing vehicle. As the container of the wing vehicle, a container having standard dimensions for wing vehicles, for example, a container having domestic standard dimensions, is preferable.

[0024] By reusing the container of the wing vehicle for the structure 10, the structure 10 can be transported using various means of transportation such as automobiles and forklifts and installed at the desired location. Also, since the container of the wing vehicle is robust, it is possible to prevent abnormalities from occurring in internal equipment and the like due to vibrations and impacts during transportation. Furthermore, the structure 10 that reuses the container of the wing vehicle can be transported within the width limit under the Road Traffic Law. Also, by reusing the container of the wing vehicle, it is possible to efficiently exhibit the function as a transportable power supply system while suppressing costs. Furthermore, it is preferable from the perspective of SDGs.

[0025] Hereinafter, in the structure 10 according to the present embodiment, points different from the container of the wing vehicle will be described.

[0026] <<Warning sound generator etc.>> FIG. 6 is a side view showing an example of the portable power supply system according to the present embodiment. In the example shown in FIG. 6, an activation switch 21, an operation switch 22, and a warning sound generator are installed on the rear wall 2 of the structure 10. Note that these warning sound generators etc. may be installed on the front wall 1 of the structure 10, or may be installed on the side wall or the ceiling wall.

[0027] The activation switch 21 is electrically connected to the power supply unit 30 and switches the availability of power supply from the power supply unit 30. The operation switch 22 is electrically connected to the activation switch 21 and operates the opening and closing operation of the wing roof 4 when power is supplied by the activation switch 21. The warning sound generator (not shown) generates a warning sound based on a signal input by the operation of the operation switch 22. The power supply unit 30, the activation switch 21, the operation switch 22, and the warning sound generator are electrically connected via wiring inside and / or outside the structure 10.

[0028] After the user switches the start switch 21 from off to on, the user operates the opening and closing operation of the wing roof 4. That is, in order to perform the opening and closing operation of the wing roof 4, it is necessary to operate two switches: the start switch 21 and the operation switch 22. Thereby, it is possible to prevent the user from accidentally performing the opening and closing operation of the wing roof 4. Further, when the wing roof 4 is opened and closed by the operation switch 22, a warning sound is generated from the warning sound generating device. Thereby, it is possible to call the attention of the user of the system 100 and passers-by in the vicinity of the system 100.

[0029] Further, a speaker (not shown) that forms part of the warning sound generating device may be provided on the peripheral wall of the structure 10. This speaker can generate a warning sound toward the outside. Thereby, it is possible to more surely call the attention of passers-by in the vicinity of the structure 10, and the system 100 can be used more safely.

[0030] In a commercially available wing vehicle, the operation switch 22 is provided, but the start switch 21 and the warning sound generating device are not installed.

[0031] <<Wing Roof Support Member>> At least one of the front wall 1 and the rear wall 2 of the structure 10 is provided with a wing roof support member 8 for supporting the wing roof 4 in the open position. Thereby, it is possible to prevent the wing roof 4 from falling, and the system 100 can be used more safely. The shape and the like of the wing roof support member 8 are not particularly limited as long as it can support the wing roof 4. For example, it may be a rod-shaped member such as a telescopic type, a folding type, or a multi-stage type, or it may be a support column or the like. In a commercially available wing vehicle, the wing roof support member 8 is not provided.

[0032] <<Reinforcing Member>> On the back surface of the bottom wall 3 of the structure 10 (the surface facing the ground during installation), a reinforcing member (not shown) is provided to suppress deformation during the conveyance and installation of the system 100. When using a commercially available container of a wing vehicle, the container will be distorted in the planar direction during installation. Also, there is a possibility that distortion will occur similarly during conveyance by a forklift or the like. To avoid these, in the structure 10 according to the present embodiment, a reinforcing member is provided on the back surface of the bottom wall 3 (the surface in contact with the ground during installation). The size, material, shape, etc. of the reinforcing member are not particularly limited as long as the structure 10 does not distort during installation and conveyance, and can be appropriately designed. For example, from the viewpoints of robustness and weight reduction, the material of the reinforcing member is an aluminum material, the size of the reinforcing member is about 25% or more of the area of the back surface of the bottom wall 3, and the shape of the reinforcing member preferably has an H shape with an H-shaped cross section.

[0033] <<Housing>> In the working space of the structure 10, it is preferable that a chair-integrated housing 40 is installed on the bottom wall 3. As shown in FIG. 1, it is preferable that a hydraulic pump 7 for supplying hydraulic oil to a hydraulic cylinder 6 that drives the opening and closing of the wing roof 4 is housed in the housing 40. Also, it is preferable that a storage battery 32 that constitutes a power supply unit 30 described later is housed in the housing 40. Thereby, the space of the working space can be effectively utilized. Also, for example, it can be used for the rest of the user during equipment charging.

[0034] <<Any other member>> The structure 10 may have other members installed as necessary. For example, the structure 10 may be provided with a partition plate or the like for partitioning the working space. Also, various devices may be installed in the working space of the structure 10 according to the purpose of use of the system 100. For example, electric devices such as an indoor unit of an air conditioner, lighting fixtures, and office equipment such as a printer may be installed in the working space of the structure 10. Also, electric devices such as an outdoor unit of an air conditioner may be installed on the outer surface of the structure 10.

[0035] The portable power supply system 100 of this embodiment is usually transported to the destination by a forklift, but it may be transported by, for example, a truck or the like. In this case, the structure 10 preferably has a hook portion for being lifted by the crane of the truck.

[0036] <Solar power generation device 11> As shown in FIG. 4, the solar power generation device 11 includes a solar panel 11a that receives sunlight and performs photoelectric conversion, and a solar panel base 11b that attaches the solar panel 11a to the wing roof 4 of the structure 10. The solar panel 11a and the solar panel base 11b may be commercially available solar panel 11a and solar panel base 11b. The size of the total light-receiving surface of the solar panel 11a is not particularly limited as long as it can be attached to the wing roof 4, and it may be appropriately designed according to the required power and the like.

[0037] FIG. 7 is an enlarged partial view of part A in FIG. 2. In the example shown in FIG. 7, on the surface of the wing roof 4 facing the back surface of the solar panel base 11b, fastening members 12 for fastening the solar panel base 11b are provided. That is, the solar panel base 11b is attached onto the wing roof 4 via the fastening members 12. A plurality of fastening members 12 are provided at predetermined intervals in the longitudinal direction of the wing roof 4, and each fastening member is provided, for example, arranged in parallel.

[0038] The fastening member 12 is made of, for example, a rectangular metal body and is in a thin plate shape. The outer surface of the wing roof 4 and the solar panel base 11b are fastened and fixed with nuts and bolts via one or a plurality of fastening members 12. In the example shown in FIG. 6, the solar panel base and the outer surface of the wing roof 4 are fastened via two fastening members. More specifically, in the example shown in FIG. 6, from the outside of the structure 10 toward the working space, the solar panel base 11b, the first fastening member 12, the wing roof 4, and the second fastening member 12 are arranged in this order, and these are fastened and fixed with nuts and bolts.

[0039] By attaching the solar power generation device 11 via the fastening member 12, the solar power generation device 11 can be firmly fastened onto the wing roof 4. Therefore, it is possible to prevent the solar power generation device 11 from detaching from the wing roof 4 even during a typhoon or the like. Further, by attaching the solar power generation device 11 via the fastening member 12, there will be a gap of about 0.5 to 1.5 cm in the thickness of the fastening member 12 between the outer surface of the wing roof 4 and the solar panel base 11b. Due to this gap, heat generated from the solar panel 11a and heat of the outside air passing through the solar panel 11a are not directly transmitted to the wing roof 4 of the structure 10. Thereby, heat conduction to the working space is suppressed, and the working space can be maintained at a comfortable temperature.

[0040] <<Any other arbitrary member>> The solar power generation device 11 may have other members installed as necessary. For example, the solar panel base 11b may be provided with, for example, hinges or the like in order to adjust the angle of the solar panel 11a, and may be configured to be deployable and foldable. Further, the solar panel base 11b may be provided with, for example, a rotating member or the like in order to adjust the position of the solar panel 11a, and the solar panel 11a may be configured to be rotatable.

[0041] <Power supply unit> As shown in FIG. 2, the power supply unit 30 has a control device 31 and a storage battery 32. The control device 31 controls to input the power generated by the solar power generation device 11 into the storage battery 32 and supply the power input into the storage battery 32 to electrical equipment. The storage battery 32 stores the power generated by the solar power generation device 11 and supplies this stored power to electrical equipment as necessary.

[0042] The control device 31 is composed of a computer, a program, an electronic circuit, etc. The control device 31 has, for example, a solar controller function for controlling the charging of the power generated by the solar power generation device 11 in the storage battery 32, and an inverter or the like for converting the power stored in the storage battery 32 into alternating current of a sine wave similar to commercial alternating current or alternating current of a rectangular wave.

[0043] The control device 31 is configured to be able to supply power to various electrical devices installed in the work space. For example, an outlet is provided inside and / or outside the structure 10, and the outlet is electrically connected to the control device 31. By connecting the electrical cable of the electrical device to the outlet, the electrical device can be used.

[0044] Note that the solar power generation device 11 has a problem that the power generation amount decreases during cloudy days and the like, and stable power cannot be supplied. Since the portable power supply system 100 according to the present embodiment includes a storage battery 32 for storing the power generated by the solar power generation device 11, it is possible to supply stable power to the electrical device even during cloudy days and the like.

[0045] <<Any other optional member>> The power supply unit 30 may have other functions as necessary. For example, the control device 31 may be a commercially available power conditioner. In this case, the control device 31 may have, for example, a maximum power point tracking control (MPPT control) function and a system connection protection function for shutting off the output of the control device 31 in case of an abnormality. Further, the control device 31 may have, for example, a display function for displaying the power generation amount of the solar power generation device 11, a monitoring function for monitoring the power generation amount and the remaining capacity of the storage battery 32, and the like.

[0046] The power supply unit 30 may have, for example, a power connection unit that receives power supply from a utility power supply or the like. Thereby, when the power generation amount of the solar power generation device 11 is insufficient, power can be supplemented from the utility power supply.

[0047] (Applications of the Portable Power Supply System) Since the portable power supply system 100 of the present embodiment is configured such that the sides and the top of the structure 10 can be opened, it can be used for various applications. Hereinafter, examples of the applications of the portable power supply system 100 of the present embodiment will be described, but the present invention is not limited thereto.

[0048] In the event of a natural disaster such as an earthquake, the system 100 may be transported to the affected area and the electricity generated by the solar power generation device 11 may be used as a power source for water purification equipment, cooking equipment, etc. installed in the work space, allowing the system to be used as a facility for providing meals, etc. In addition, the electricity generated by the solar power generation device 11 may be used as a power source for disaster relief equipment such as charging mobile devices and lighting in the affected area. By opening up the sides and top of the structure 10, meals, etc. can be provided more efficiently.

[0049] In the event of a natural disaster such as an earthquake, the system 100 can be transported to the affected area and used as a temporary living facility by using the electricity generated by the solar power generation device 11 to power daily life appliances such as lighting equipment, cooking equipment, refrigeration equipment, and air conditioning equipment installed in the work space.

[0050] In recent years, electric cars, electric bicycles, electric carts, electric wheelchairs, electric kick scooters, etc. are becoming more and more popular as electric transportation means. These electric transportation means, which are means for moving people and things using electricity, are expected to become more and more popular in the future amid the global trend of reducing carbon dioxide emissions. In particular, in Japan, electric kick scooters and the like that meet certain standards will be classified as "specific small motorized bicycles," a type of motorized bicycle, according to the revised Road Traffic Act that came into effect on July 1, 2023, and are expected to become more and more popular in the future. Therefore, after the system 100 is transported to a station, a parking lot, a service area on a highway, etc., the sides and the top of the structure 10 may be opened, and the electricity generated by the solar power generation device 11 may be used as a power source for charging the storage battery 32 of the electric transportation means. In other words, the system 100 may be used as a charging facility for electric transportation means.

[0051] In addition, after the system 100 is transported to a station or the like, the sides and top of the structure 10 can be opened, and electric transportation means and ports for parking and charging the means can be installed in the work space, allowing the system to be used as a shared bicycle or rental bicycle facility. Furthermore, the system 100 can be transported to an evacuation shelter or the like in a disaster area and used as a shared bicycle or rental bicycle facility, providing a temporary means of transportation for evacuees.

[0052] A personal computer, a projector, a monitor, etc. may be installed in the work space, and the system 100 may be used as a conference room or a study room. Also, by opening up the sides and the top of the structure 10, it may be used as a seminar venue.

[0053] Coin lockers, vending machines, ticket vending machines, etc. may be installed in the work space, and the system 100 may be transported to an event venue or the like and installed during the event. By opening the sides and top of the structure 10, more users can use it efficiently.

[0054] The work space may be equipped with medical equipment and the system 100 may be used as a mobile clinic.

[0055] Cooking equipment, a refrigerator, etc. may be installed in the work space, and the system 100 may be used as a store such as a cafe. In addition, by opening up the sides and the top of the structure 10, the system 100 may be used as an open cafe, a beach house, or the like.

[0056] According to the portable power supply system 100 of the present embodiment described above, since the structure 10 is transportable, the structure 10 on which the solar power generation device 11 is mounted can be easily transported. Since the power generated by the solar power generation device 11 is supplied to the electrical equipment provided in the structure 10, the portable power supply system 100 can be used in places where a grid power source cannot be used and in non-electrified areas. Furthermore, unlike conventional sealed containers, the portable power supply of the present embodiment is provided with a wing roof 4 that can be opened and closed, so that the sides and the top of the structure 10 can be opened. As a result, when the system 100 is stored or transported, the sides and the top of the structure 10 are closed to provide a compact shape with a sealed working space like a conventional container, while when the system 100 is used or when the solar power generation device 11 is used, the sides and the top of the structure 10 can be opened to provide an expanded working space. In other words, in addition to applications suitable for enclosed work spaces such as temporary housing and offices, the system 100 can also be suitably used for applications suitable for open work spaces such as stores such as open cafes, beach houses, event facilities for athletic meets and sporting events, shared bicycles, and rental bicycles.
