Description

The present invention relates to a portable power supply system. In particular, the present invention relates to a portable power supply system equipped with a solar power generation device.

Conventionally, a mobile sales vehicle is known as a portable facility that sells products from a store installed in the loading platform of the vehicle. Portable facilities such as mobile sales vehicles mainly use on-board batteries as a power source for the electrical equipment mounted in the loading platform of the vehicle. However, if the facility is to be 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 generator that uses fossil fuels instead of on-board batteries, but this requires refueling.

For example, if portable equipment is used in disaster-stricken areas, if a disaster cuts off transportation networks or destroys ground infrastructure, refueling will not be possible, and equipment equipped with generators that use fossil fuels may not be able to provide the rescue or support required.

In response to this, portable equipment equipped with a power generation unit that uses natural energy has been proposed as a type of portable equipment 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).

Patent Document 1 proposes a portable container-type facility that uses a container that can be transported by truck or the like, and that includes a solar panel component and a storage battery for storing the electricity generated by the solar panel component. It has been reported that the container-type portable facility of Patent Document 1 stably supplies electricity to electrical equipment without the need for construction work to lay electric wires or the like. The container-type portable facility of Patent Document 1 is expected to be used in temporary housing, temporary stores, temporary offices, etc. during disasters, etc.

Utility Model Registration No. 3222644

However, even if the container-type portable equipment as in Patent Document 1 has a total floor area of more than 10 ^m2 , it falls under the category of a building under the Building Standards Act. For this reason, when installing the portable equipment, procedures based on the Building Standards Act must be carried out, and it was not easy to install. In addition, when the container-type portable equipment is loaded onto a vehicle or the like and transported to a destination, if the vehicle carrying the portable equipment has a height during travel exceeding 3.8 m, a length during travel exceeding 12.0 m, or a width during travel exceeding 2.5 m, it falls under the category of a special vehicle under the law (Road Act and Vehicle Restriction Order). Special vehicles need to obtain a special vehicle traffic permit when traveling on public roads, which takes time and effort. Therefore, the container-type portable equipment as in Patent Document 1 is inevitably a small facility when considering the time and effort required for transportation and installation. For this reason, the container-type portable equipment as in Patent Document 1 cannot be used for applications requiring a relatively large space, and there is room for improvement from the viewpoint of versatility.

The present invention was made in light of this 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.

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

(Portable power supply system)
1 to 4 are perspective views showing an example of a portable power supply system according to the present embodiment.
FIG. 5 is a front view showing an example of a portable power supply system according to the present embodiment.
The portable power supply system 100 of this embodiment mainly comprises a box-shaped structure 10, a solar power generation device 11, and a power supply unit 30.

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 the 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 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 .

According to the above-mentioned 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.
In addition, the provision of the solar power generation device 11, which is one type of natural energy power generation device, makes it possible to cover the electricity required for use without using the power grid of a power company (off-grid type). In other words, even in areas where it is difficult to secure a power source, such as unelectrified areas where a power grid is not in place or disaster areas, it is possible to operate electrical equipment, making it easy to operate the system 100. In addition, because it is natural energy, it is possible to supply electricity in a clean manner with little environmental impact.

Furthermore, unlike conventional sealed containers, the structure 10 of this embodiment is provided with a wing roof 4 that can be opened and closed, and therefore the sides and the top of the structure 10 can be opened. As a result, the system 100 can be used in a compact shape with a sealed working space like a conventional container by closing the sides and the top of the structure 10 during storage, transportation, etc., as shown in Fig. 4, and can be used to expand the working space by opening the sides and the top of the structure 10 during use, etc., as shown in Figs. 1 and 2. That is, the system 100 can be suitably used for applications suitable for sealed working spaces such as temporary housing, offices, and the like, as well as applications suitable for open working spaces such as shops such as open cafes, beach houses, event facilities such as athletic meets and sports competitions, shared bicycles, rental bicycles, and the like.
Below, each of the components constituting the system 100 will be explained.

<Structure 10>
The structure 10 is formed in a generally rectangular parallelepiped shape as a whole. The structure 10 has, as its main components, 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.

A front wall 1 having a front frame and left and right opening doors that are rotatably supported by the front frame and open and close 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 doors of the front wall 1 open, people can move in and out of the work space.

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, with 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 of the ceiling surface body in the width direction and constitutes the upper part of the side wall of the structure 10. In other words, each wing roof 4 constitutes 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 located approximately in the center of the upper part of the front wall 1 and the rear wall 2.

1 to 3, when generating power by the solar power generation device 11 and when the system 100 is in use, each wing roof 4 is driven to an open position and the sides and top of the structure 10 are opened. This allows efficient power generation by the solar power generation device 11. In addition, since the working space of the structure 10 becomes an open space rather than an enclosed space, it becomes possible to use the structure 10 in a way that is more suited to 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 a destination. It can also be used when the system 100 is in use. Since the working space of the structure 10 is an enclosed space, it can be used in the same way as a conventional container.

In addition, the gates 5 may be provided at both the left and right ends of the bottom wall 3 of the structure 10 so as to be openable and closable. The gates 5 are rotatably supported on the side edges of the bottom wall 3 of the structure 10 via a plurality of hinges, and constitute the lower side of the structure 10 in an upright state standing along the length of the bottom wall 3, and open the lower side of the structure 10 in a tilted state rotated downward from the upright state. A center pillar that can be set to an upright state and a tilted state may be rotatably supported via a hinge similar to the gates 5 at approximately the center of the side edges in the length direction of the bottom wall 3. If there is a center pillar, the gates 5 are divided into front and rear with the center pillar as a boundary, and the front gates 5 and the rear gates 5 are independently set to an upright state and a tilted state. As shown in Figures 1 and 2, the gates 5 are usually used in an open state during work within the structure 10. This allows people to come and go from the sides of the structure 10 to the work space, and the system 100 can be used according to its purpose. On the other hand, as shown in Figures 3 and 4, the gate 5 is usually used in a closed state during storage, transportation, etc. This allows the system 100 to be stored and transported in a compact manner.

The size of the structure 10 is not particularly limited, but it is preferable that the length is approximately 3.1 m to 9.6 m, the width is approximately 1.7 m to 2.4 m, and the height is approximately 1.9 m to 2.6 m. If the size of the structure 10 is within the above ranges, it will not be considered a special vehicle when transporting it by vehicle, etc.

The structure 10 of this 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 this embodiment is preferably a reused container for a winged vehicle. The container for the winged vehicle is preferably a container with standard dimensions for winged vehicles, for example, a container with dimensions according to domestic standards.

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 transport means such as automobiles and forklifts. In addition, since the container of a wing vehicle is robust, it is possible to prevent abnormalities in the internal equipment, etc. caused by vibrations and shocks during transport. Furthermore, a structure 10 made by reusing a container of a wing vehicle 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 perform the function of a transportable power supply system while keeping costs down. Furthermore, this is also preferable from the perspective of the SDGs.

Below, we will explain the differences between the structure 10 of this embodiment and the container of a wing vehicle.

<<Warning sound generating devices, etc.>>
FIG. 6 is a side view showing an example of the portable power supply system according to the present embodiment.
6, a start switch 21, an operation switch 22, and an alarm sound generating device are provided on the rear wall 2 of the structure 10. These alarm sound generating devices and the like may be provided on the front wall 1 of the structure 10, or on a side wall or a ceiling wall.

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.

The user switches the start switch 21 from off to on, and then operates the opening and closing operation of the wing roof 4. That is, to open or close the wing roof 4, it is necessary to operate two switches, the start switch 21 and the operation switch 22. This prevents the user from opening or closing the wing roof 4 by mistake. In addition, when the wing roof 4 is opened or closed by the operation switch 22, a warning sound is generated 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.

A speaker (not shown) constituting part of the warning sound generating device may also be provided on the perimeter 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 it possible to use the system 100 more safely.

Note that commercially available wing vehicles are equipped with an operation switch 22, but do not have a start switch 21 or a warning sound generator.

<<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. This makes it possible to prevent the wing roof 4 from falling, and makes the system 100 safer to use.
The shape of the wing roof support member 8 is not particularly limited as long as it is capable of supporting the wing roof 4. For example, it may be a rod-like member of an extendable, foldable, or multi-stage type, or it may be a pillar or the like.
It should be noted that in commercially available wing vehicles, the wing roof support member 8 is not provided.

<<Reinforcing member>>
A reinforcing member (not shown) is provided on the back surface (surface facing the ground when installed) of the bottom wall 3 of the structure 10 to suppress deformation during transportation and installation of the system 100. When a commercially available wing vehicle container is used, distortion occurs in the planar direction when the container is installed. In addition, distortion may occur similarly during transportation by a forklift or the like. In order to avoid these, a reinforcing member is provided on the back surface (surface contacting the ground when installed) of the bottom wall 3 of the structure 10 according to this embodiment. The size, material, shape, etc. of the reinforcing member are not particularly limited as long as distortion does not occur in the structure 10 during installation and transportation, and can be designed appropriately. For example, the material of the reinforcing member is aluminum from the viewpoint of robustness and weight reduction, 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 is preferably an H-shaped cross section having an H-shaped shape.

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

<<Other optional components>>
The structure 10 may be provided with other members as necessary. For example, the structure 10 may be provided with a partition plate or the like for dividing the work space. In addition, various devices may be installed in the work space of the structure 10 according to the purpose of use of the system 100. For example, electrical devices such as an indoor unit of an air conditioner, lighting equipment, and office equipment such as a printer may be installed in the work space of the structure 10. In addition, electrical devices such as an outdoor unit of an air conditioner may be installed on the outer surface of the structure 10.

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 vehicle. In this case, it is preferable that the structure 10 has a hook portion for being lifted by the crane of the crane vehicle.

<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 performs photoelectric conversion, and a solar panel stand 11b that mounts the solar panel 11a to the wing roof 4 of the structure 10. The solar panel 11a and the solar panel stand 11b may be commercially available solar panels 11a and solar panel stands 11b. The size of the total light receiving surface of the solar panel 11a is not particularly limited as long as it is large enough to be mounted on the wing roof 4, and may be appropriately designed according to the required power, etc.

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

The fastening member 12 is, for example, made of rectangular metal and has a thin plate shape. The outer surface of the wing roof 4 and the solar panel base 11b are fastened 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 with two fastening members. More specifically, in the example shown in FIG. 6, 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 from the outside of the structure 10 toward the work space, and these are fastened with nuts and bolts.

The solar power generation device 11 can be firmly fastened to the wing roof 4 by attaching it via the fastening members 12. This prevents the solar power generation device 11 from detaching from the wing roof 4 even during a typhoon. Also, by attaching the solar power generation device 11 via the fastening members 12, a gap of about 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. Due to the existence of this gap, the heat generated by the solar panel 11a and the heat of the outside air via the solar panel 11a are not directly transmitted to the wing roof 4 of the structure 10. This prevents heat conduction to the work space from occurring, making it possible to maintain the work space at a comfortable temperature.

<<Other optional components>>
Other members may be installed in the solar power generation device 11 as necessary. For example, the solar panel stand 11b may be configured to be unfoldable or foldable by including, for example, a hinge in order to adjust the angle of the solar panel 11a. Also, the solar panel stand 11b may be configured to be configured to be rotatable by including, for example, a rotating member in order to adjust the position of the solar panel 11a.

<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 supplies 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.

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.

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 electrical outlet.

However, the solar power generation device 11 has a problem in that the amount of power generated decreases on cloudy days, etc., making it unable to supply stable power. The portable power supply system 100 according to this embodiment is equipped with a storage battery 32 for storing the power generated by the solar power generation device 11, so that it is possible to supply stable power to electrical equipment even on cloudy days, etc.

<<Other optional components>>
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.

The power supply unit 30 may have a power supply connection unit that receives power supply from a power grid or the like. 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.

(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 the present embodiment will be described below, but the present invention is not limited to these.

In the event of a natural disaster such as an earthquake, the system 100 can be transported to the affected area and the electricity generated by the solar power generation device 11 can be used to power water purification equipment, cooking appliances, 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 can 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.

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.

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 use electricity to move people and things, 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 other such vehicles that meet certain standards will be classified as "specific small motorized bicycles," a type of motorized bicycle, under 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, parking lot, highway service area, etc., the sides and top of the structure 10 can be opened, and the electricity generated by the solar power generation device 11 can be used as a power source for charging the storage battery 32 of the electric transportation means. In other words, the system 100 can be used as a charging facility for electric transportation means.

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 means of transportation and ports for parking and charging the means 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.

The system 100 can 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 can be used as a seminar venue.

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

Medical equipment may be installed in the workspace and the system 100 may be used as a mobile clinic.

The system 100 may be used as a store such as a cafe by installing cooking equipment, refrigerators, 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, beach house facility, etc.

According to the portable power supply system 100 of the present embodiment described above, the structure 10 is transportable, so that the structure 10 on which the solar power generation device 11 is mounted can be easily transported. Since the electric power generated by the solar power generation device 11 is supplied to the electric equipment installed 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 top of the structure 10 can be opened. As a result, when the system 100 is stored or transported, the sides and top of the structure 10 are closed to provide a compact shape with a sealed working space like a conventional container, while when the solar power generation device 11 is generating electricity or the system 100 is being used, the sides and top of the structure 10 can be opened to provide an expanded working space. In other words, the system 100 can be used in applications suitable for closed work spaces such as temporary housing and offices, as well as in open work spaces such as shops such as open cafes, beach houses, event facilities for athletic meets and sporting events, bicycle sharing, and bicycle rentals.

The above describes the mode for carrying out the present invention based on the embodiment, but the embodiment disclosed herein is illustrative in all respects and is not restrictive. The scope of the present invention is indicated by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
