Description

[Technical Field]

[0001] The present invention relates to a portable power supply system, and more particularly to a portable power supply system equipped with a solar power generation device. [Background technology]

[0002] Conventionally, mobile sales vehicles, which are stores set up in the cargo area of a vehicle and sell products, have been known as portable facilities. Portable facilities such as mobile sales vehicles primarily use on-board batteries as a power source for the electrical equipment mounted in the cargo area of the vehicle. However, if the facility is installed in the same location for an extended period of time, the vehicle used for transportation becomes unnecessary. For this reason, it is desirable to install the facility separately from the vehicle. In this case, the on-board battery cannot be used, making it difficult to secure a power source in unelectrified areas or disaster-stricken areas where portable facilities are particularly needed. It is also possible to install a fossil fuel-powered generator in the facility instead of an on-board battery, but this would require refueling.

[0003] For example, if portable equipment is to be used in disaster-stricken areas, if a disaster cuts off transportation networks or destroys ground infrastructure, it will be impossible to refuel, and equipment equipped with fossil fuel-powered generators may not be able to provide rescue or assistance as needed.

[0004] In response to this, a portable facility equipped with a power generation unit that uses natural energy has been proposed as a portable facility that is highly transportable and can be operated in areas where it is difficult to secure a power source (see, for example, Patent Document 1).

[0005] Patent Document 1 proposes a portable container-type facility that uses a container that can be transported by truck or the like and includes solar panel components and a storage battery for storing the electricity generated by the solar panel components. The portable container-type facility of Patent Document 1 is reported to stably supply electricity to electrical equipment without the need for construction work such as laying electrical wires. The portable container-type facility of Patent Document 1 is expected to be used in temporary housing, temporary stores, temporary offices, etc. during disasters, etc. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3222644 Summary of the Invention [Problem to be solved by the invention]

[0007] However, even with a container-type portable facility such as that in Patent Document 1, the total floor area is 10 m 2 If the container-type portable equipment exceeds this limit, it will be considered a building under the Building Standards Act. Therefore, installing portable equipment requires procedures under the Building Standards Act, making installation difficult. Furthermore, when a container-type portable equipment is loaded onto a vehicle or the like and transported to a destination, if the vehicle carrying the portable equipment exceeds 3.8 m in height, 12.0 m in length, or 2.5 m in width while traveling, it will be considered a special vehicle under the law (Road Act and Vehicle Restrictions Order). Special vehicles must obtain a special vehicle permit to travel on public roads, which requires time and effort. Therefore, container-type portable equipment such as that described in Patent Document 1 is inevitably small, considering the time and effort required for transportation and installation. Therefore, container-type portable equipment such as that described in Patent Document 1 cannot be used for applications requiring a relatively large space, and there is room for improvement in terms of versatility.

[0008] The present invention has been made in consideration of the above background, and aims to provide a portable power supply system that is highly portable, can be used in areas where it is difficult to secure a power source, and can be used for a variety of purposes. [Means for solving the problem]

[Figure 7] FIG. 3 is an enlarged view of a portion A in FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

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

[0013] (Portable power supply system) 1 to 4 are perspective views showing an example of a portable power supply system according to this embodiment. FIG. 5 is a front view showing an example of a portable power supply system according to this embodiment. The portable power supply system 100 of this embodiment includes, as its main components, a box-shaped structure 10, a solar 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 forms at least a part of the top and side walls and is driven to open and close upward. Inside the box-shaped structure 10 is a work space where people can work. The solar power generation device 11 has a plurality of solar panels 11a provided on a wing roof. The power supply unit 30 is installed in the structure 10 and supplies the power generated by the solar power generation device 11.

[0015] According to the above configuration, the structure 10 is configured to be transportable, and thus has high transportability. In this specification, "transportable" means that the bottom wall 3, etc. of the structure 10 are not fixed to the ground, other facilities, etc. Furthermore, by providing a solar power generation system 11, which is a type of natural energy power generation system, the system can generate the electricity required for use without using the power grid of a power company (an off-grid type). In other words, electrical equipment can be operated even in areas where it is difficult to secure a power source, such as unelectrified areas where the power grid is not in place or disaster-stricken areas, making it easy to operate the system 100. Furthermore, because it is natural energy, it is possible to supply power in a clean manner with little environmental impact.

[0016] Furthermore, unlike conventional sealed containers, the structure 10 of this embodiment is equipped with a wing roof 4 that can be opened and closed, and therefore the sides and top of the structure 10 can be opened. As a result, the system 100 can close the sides and top of the structure 10 during storage, transportation, etc., as shown in FIG. 4, to provide a compact shape with a sealed workspace similar to that of a conventional container, while opening the sides and top of the structure 10 during use, etc., as shown in FIGS. 1 and 2, to enable use with an expanded workspace. That is, the system 100 can be suitably used not only for applications suitable for sealed workspaces such as temporary housing and offices, but also for applications suitable for open workspaces such as shops like open cafes, beach huts, event facilities for athletic meets and sports competitions, bicycle sharing and rental bicycles, etc. Below, each of the components constituting the system 100 will be explained.

[0017] <Structure 10> The structure 10 is formed in a generally rectangular parallelepiped shape. The main components of the structure 10 are a front wall 1, a rear wall 2, a bottom wall 3, and a wing roof 4 that forms at least a portion of the top and side walls and can be driven to open and close upward.

[0018] A front wall 1 having a front frame and left and right opening / closing doors rotatably supported by the front frame for opening and closing the front of the structure 10 is erected at the front end of the bottom wall 3 of the structure 10, and a rear wall 2 is erected at the rear end of the bottom wall 3 of the structure 10. With the opening / closing doors of the front wall 1 open, people can move in and out of the work space.

[0019] A pair of left and right wing roofs 4 are provided between the front wall 1 and the rear wall 2. Each wing roof 4 has a substantially L-shaped cross section, including a ceiling surface body that forms the top wall of the structure 10, and side surfaces that extend substantially vertically downward from the outer widthwise edges of the ceiling surface body and form the upper parts of the side walls of the structure 10. In other words, each wing roof 4 forms at least a part of the top wall and side wall of the structure 10, and has an L-shaped cross section. Each wing roof 4 is driven to open and close between a closed position and an open position by a hydraulic cylinder 6 that is located approximately in the center of the upper part of the front wall 1 and the rear wall 2.

[0020] 1 to 3, when generating power using the solar power generation device 11 and when using the system 100, each wing roof 4 is driven to the open position, and the sides and top of the structure 10 are opened. This allows for efficient power generation by the solar power generation device 11. In addition, since the working space of the structure 10 changes from an enclosed space to an open space, it becomes possible to use the structure 10 in a way that better suits the purpose of the user. As shown in FIG. 4, during storage, transportation, etc., each wing roof 4 is driven to a closed position, and the sides and top of the structure 10 are closed. This makes the structure 10 compact and robust, and provides excellent storage properties. In addition, the system 100 can be efficiently transported to its destination. This can also be used when the system 100 is in use. Because the working space of the structure 10 is an enclosed space, it can be used in the same way as a conventional container.

[0021] In addition, gates 5 may be provided at both left and right ends of the bottom wall 3 of the structure 10 in an openable and closable manner. The gates 5 are rotatably supported on the side edges of the bottom wall 3 of the structure 10 via multiple hinges, and constitute the lower lateral sections of the structure 10 in an upright state standing along the length of the bottom wall 3. When rotated downward from the upright state, the lower lateral sections of the structure 10 are opened. A center pillar, which can be set to an upright state or a reclined state, may be rotatably supported via a hinge, similar to the gates 5, at approximately the center of the side edges of the bottom wall 3 in the length direction. If a center pillar is present, the gates 5 are divided into front and rear sections with the center pillar as a boundary, and the front gates 5 and rear gates 5 are independently set to an upright state or a reclined state. As shown in FIGS. 1 and 2, the gates 5 are normally used in an open state during work within the structure 10. This allows people to access the work space from the sides of the structure 10, enabling the system 10 to be used according to its intended purpose. 3 and 4, the gate 5 is normally used in a closed state during storage, transportation, etc. This allows the system 100 to be stored and transported in a compact manner.

[0022] The size of the structure 10 is not particularly limited, but it is preferable that the length is about 3.1 m to 9.6 m, the width is about 1.7 m to 2.4 m, and the height is about 1.9 m to 2.6 m. If the size of the structure 10 is within the above ranges, it does not fall under the category of a special vehicle when transporting it by vehicle or the like.

[0023] The structure 10 of this embodiment is not a self-propelled structure 10, but a structure 10 that can be transported and moved by a transport means or the like. The structure 10 of this embodiment is preferably a reused container for a winged vehicle. The container for the winged vehicle is preferably a container of standard dimensions for winged vehicles, for example, a container of domestic standard dimensions.

[0024] By reusing the container of a wing vehicle for the structure 10, the structure 10 can be transported and installed at the desired location using various transportation means such as automobiles and forklifts. In addition, because the container of a wing vehicle is robust, it is possible to prevent abnormalities in the internal equipment, etc., due to vibrations and shocks during transportation. Furthermore, the structure 10 made from a reused wing vehicle container can be transported within the width limit set by the Road Traffic Act. Furthermore, by reusing the container of a wing vehicle, it is possible to efficiently function as a transportable power supply system while keeping costs down. Furthermore, this is also preferable from the perspective of SDGs.

[0025] Below, the differences between the structure 10 according to this embodiment and the container of a wing vehicle will be described.

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

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

[0028] The user switches the activation switch 21 from off to on, and then operates the opening and closing operation of the wing roof 4. In other words, to open or close the wing roof 4, it is necessary to operate two switches, the activation switch 21 and the operation switch 22. This prevents the user from opening or closing the wing roof 4 by mistake. Furthermore, when the wing roof 4 is opened or closed by the operation switch 22, a warning sound is emitted from the warning sound generating device. This makes it possible to alert users of the system 100 and passersby in the vicinity of the system 100.

[0029] Furthermore, a speaker (not shown) constituting part of the warning sound generating device may be provided on the peripheral wall of the structure 10. This speaker can emit a warning sound to the outside. This can more reliably alert passersby and others around the structure 10, making the system 100 safer to use.

[0030] In addition, commercially available wing vehicles are provided with the operation switch 22, but are not provided with the start switch 21 or the warning sound generating device.

[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 preventing the wing roof 4 from falling and making the system 100 safer to use. There are no particular limitations on the shape of the wing roof support member 8 as long as it is capable of supporting the wing roof 4. For example, it may be a rod-shaped member such as an extendable, foldable, or multi-stage member, or it may be a support pillar or the like. It should be noted that commercially available wing vehicles are not provided with the wing roof support member 8.

[0032] <<Reinforcing material>> A reinforcing member (not shown) is provided on the back surface of the bottom wall 3 of the structure 10 (the surface facing the ground when installed) to suppress deformation during transportation and installation of the system 100. When a commercially available winged vehicle container is used, distortion occurs in the planar direction when the container is installed. Similar distortion may also occur during transportation using a forklift or the like. To avoid this, a reinforcing member is provided on the back surface of the bottom wall 3 of the structure 10 according to this embodiment (the surface that comes into contact with the ground when installed). The size, material, shape, etc. of the reinforcing member are not particularly limited as long as they do not cause distortion in the structure 10 during installation or transportation, and can be designed appropriately. For example, the reinforcing member is preferably made of aluminum from the standpoints of robustness and weight reduction, the size of the reinforcing member is approximately 25% or more of the area of the back surface of the bottom wall 3, and the shape of the reinforcing member is preferably H-shaped, having an H-shaped cross section.

[0033] <<Case>> The work space of the structure 10 preferably has a chair-integrated housing 40 installed on the bottom wall 3. As shown in FIG. 1, the housing 40 preferably houses a hydraulic pump 7 that supplies hydraulic oil to a hydraulic cylinder 6 that drives the wing roof 4 to open and close. The housing 40 also preferably houses a storage battery 32 that constitutes a power supply unit 30, which will be described later. This allows the space in the work space to be used effectively. The space can also be used, for example, for users to take a break while their devices are being charged.

[0034] <<Other optional parts>> The structure 10 may be provided with other components as needed. For example, the structure 10 may be provided with a partition plate or the like for dividing the work space. Furthermore, various devices may be installed in the work space of the structure 10 depending on the intended use of the system 100. For example, electrical devices such as an indoor unit of an air conditioner, lighting fixtures, and office equipment such as a printer may be installed in the work space of the structure 10. Furthermore, electrical 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 may also be transported by, for example, a crane truck. In this case, the structure 10 preferably has a hook portion for being lifted by the crane of the crane truck.

[0036] <Solar power generation device 11> As shown in Fig. 4, the solar power generation device 11 has a solar panel 11a that receives sunlight and converts it into electricity, and a solar panel base 11b that mounts the solar panel 11a on the wing roof 4 of the structure 10. The solar panel 11a and the solar panel base 11b may be commercially available solar panels 11a and solar panel bases 11b. There are no particular restrictions on the size of the total light-receiving surface of the solar panel 11a, as long as it is large enough to be mounted on the wing roof 4, and it may be designed appropriately according to the required power, etc.

[0037] FIG. 7 is an enlarged view of a portion A in FIG. In the example shown in Fig. 7, fastening members 12 for fastening the solar panel base 11b are provided on the surface of the wing roof 4 opposite the back surface of the solar panel base 11b. In other words, the solar panel base 11b is attached to 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 the fastening members are arranged, for example, in parallel.

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

[0039] By attaching the solar power generation device 11 via the fastening members 12, the solar power generation device 11 can be firmly fastened to the wing roof 4. This prevents the solar power generation device 11 from detaching from the wing roof 4 even during a typhoon or the like. Furthermore, by attaching the solar power generation device 11 via the fastening members 12, a gap of approximately 0.5 to 1.5 cm in thickness of the fastening members 12 is created between the outer surface of the wing roof 4 and the solar panel base 11b. This gap prevents heat generated by the solar panels 11a and heat from the outside air passing through the solar panels 11a from being directly transmitted to the wing roof 4 of the structure 10. This prevents heat conduction to the work space, making it possible to maintain a comfortable temperature in the work space.

[0040] <<Other optional parts>> Other members may be installed as necessary in the solar power generation device 11. For example, the solar panel stand 11b may be provided with, for example, a hinge or the like to adjust the angle of the solar panel 11a, and may be configured to be unfoldable or foldable. Furthermore, the solar panel stand 11b may be provided with, for example, a rotating member or the like to adjust the position of the solar panel 11a, and may be configured to rotate the solar panel 11a.

[0041] <Power supply section> 2, the power supply unit 30 has a control device 31 and a storage battery 32. The control device 31 controls the input of power generated by the solar power generation device 11 to the storage battery 32 and the supply of the power input to the storage battery 32 to the electrical equipment. The storage battery 32 stores the power generated by the solar power generation device 11 and supplies the stored power to the electrical equipment as needed.

[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 that controls the storage of the power generated by the solar power generation device 11 in the storage battery 32, an inverter that converts the power stored in the storage battery 32 into a sine wave AC similar to commercial AC power, or into a square wave AC, etc.

[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 electrical outlet is provided inside and / or outside the structure 10, and the electrical outlet is electrically connected to the control device 31. The electrical device can be used by connecting the electrical cable of the electrical device to the outlet.

[0044] However, the solar power generation device 11 has a problem in that the amount of power generated decreases on cloudy days, making it unable to supply stable power. However, the portable power supply system 100 according to this embodiment includes a storage battery 32 for storing the power generated by the solar power generation device 11, and therefore is able to supply stable power to electrical devices even on cloudy days.

[0045] <<Other optional parts>> 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 grid connection protection function that cuts off the output of the control device 31 in the event of an abnormality. Furthermore, the control device 31 may have, for example, a display function that displays the amount of power generated by the solar power generation device 11 and a monitoring function that monitors the amount of power generated and the remaining capacity of the storage battery 32.

[0046] The power supply unit 30 may have a power supply connection unit that receives power supply from, for example, a power grid, etc. This allows power to be supplemented from the power grid when the amount of power generated by the solar power generation device 11 is insufficient.

[0047] (Use of portable power supply system) The portable power supply system 100 of this embodiment is configured so that the sides and top of the structure 10 can be opened, and therefore can be used for a variety of purposes. Examples of applications of the portable power supply system 100 of this embodiment will be described below, but the application is not limited to these.

[0048] 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 facility for providing meals, etc. by using the electricity generated by the solar power generation device 11 to power water purification equipment, cooking equipment, etc. installed in the work space. The electricity generated by the solar power generation device 11 can also be used to charge mobile devices and power disaster relief equipment such as 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 everyday appliances such as lighting equipment, cooking equipment, refrigeration equipment, and air conditioning equipment installed in the work space.

[0050] In recent years, electric vehicles such as electric cars, electric bicycles, electric carts, electric wheelchairs, and electric kick scooters have become increasingly popular as electric transportation. These electric vehicles, which use electricity to move people and goods, are expected to become increasingly popular in the future amid the global trend toward reducing carbon dioxide emissions. In particular, in Japan, electric kick scooters and other vehicles that meet certain standards are classified as "specified small motorized bicycles," a type of motorized bicycle, under the revised Road Traffic Act, which came into effect on July 1, 2023. These vehicles are expected to become increasingly popular in the future. Therefore, after transporting the system 100 to a station, parking lot, highway service area, or other location, the sides and top of the structure 10 can be opened and the electricity generated by the solar power generation system 11 can be used to charge the storage battery 32 of the electric transportation vehicle. In other words, the system 100 can be used as a charging facility for electric transportation vehicles.

[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 these can be installed in the work space, allowing it 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-stricken area and used as a shared bicycle or rental bicycle facility, providing temporary transportation for evacuees.

[0052] The system 100 may be used as a conference room or study room by installing a personal computer, projector, monitor, etc. in the work space. Also, by opening up the sides and 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 workspace may be equipped with medical equipment and the system 100 may be used as a mobile clinic.

[0055] The system 100 may be used as a cafe or other store by installing cooking equipment, a refrigerator, etc. in the work space. Also, by opening up the sides and top of the structure 10, it may be used as an open cafe, a beach hut, or other facility.

[0056] According to the portable power supply system 100 of the present embodiment described above, the structure 10 is transportable, and therefore the structure 10 equipped with the solar power generation device 11 can be easily transported. Because power generated by the solar power generation device 11 is supplied to electrical equipment installed in the structure 10, the portable power supply system 100 can be used in places where a grid power supply is unavailable or in unelectrified areas. Furthermore, unlike conventional sealed containers, the portable power supply system of the present embodiment is equipped with a wing roof 4 that can be opened and closed, allowing the sides and top of the structure 10 to be open. This allows the system 100 to have a compact shape with a sealed workspace similar to a conventional container when stored or transported, by closing the sides and top of the structure 10. However, when generating power with the solar power generation device 11 or using the system 100, the sides and top of the structure 10 can be opened, allowing for expanded workspace.
