Description

[Technical Field]

[0001] The present invention relates to a disaster power supply device for a ship that can be used as an emergency power source in the event of a disaster by charging surplus power on a small ship. [Background technology]

[0002] Electricity is the energy source that powers various electrical appliances such as lights and refrigerators, and has become one of the indispensable elements of modern society.

[0003] However, when disasters occur, such as landslides caused by heavy rain or strong winds caused by typhoons, power outages occur due to disruptions to the power grid. In particular, earthquakes can cause power outages over a wide area, and in some cases, large-scale blackouts can occur across the entire area under the jurisdiction of a power company.

[0004] Power outages that accompany such disasters are difficult to predict how long it will take to restore power, causing anxiety for those affected. This anxiety is especially heightened when communication devices that provide information, such as radio, television, and smartphones, become unusable.

[0005] Therefore, there is an urgent need to build a system that can supply electricity in the event of a power outage, separate from the power plants and power grids operated by electric power companies. Until now, the power generation function of automobiles has been used as a power source in the event of a disaster. For example, Japanese Patent Laid-Open Publication No. 2002-135906 proposes an invention for using the large-capacity batteries installed in hybrid vehicles as an emergency power source in the event of a disaster (Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-135906 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the invention described in Patent Document 1 has the problem that if roads are cut off due to an earthquake, landslide, or other reasons, it is impossible to reach evacuation sites by car. In particular, if roads are cut off on peninsulas or remote islands where there are no detours, people will be left without electricity until the roads are restored, creating an inconvenient and anxious situation. Therefore, while using a car as a generator is effective, it is necessary to secure an emergency power source other than a car in case of road cuts.

[0008] Japan is surrounded by the sea, and has many ports and ships. In particular, there are many small fishing boats in each fishing port. These small boats are equipped with engines called outboard motors, which, like automobiles, have the ability to generate electricity for operation.

[0009] Furthermore, because small vessels travel on water, they are less susceptible to landslides and other disasters, and can travel around the sea to reach their destination port, even on peninsulas or remote islands.

[0010] However, no system has been developed to date that allows small boats to use electricity generated by them as a power source in emergencies. Furthermore, to use a small boat's battery as an emergency power source, the battery must be removed from the outboard motor and carried to an evacuation site, a dangerous task for those without electrical knowledge. Another problem is that the small boat cannot be operated while the battery is disconnected.

[0011] The present invention has been made to solve the above problems, and aims to provide a disaster power supply device for ships that can be charged with surplus electricity generated by an outboard motor without interfering with the operation of the small ship, and that can be carried to an evacuation site or the like in the event of a disaster and used as an emergency power source. [Means for solving the problem]

[0012] The disaster power supply device for ships of the present invention solves the problem of charging surplus power generated by the outboard motor of a small boat and using it as a portable emergency power source in the event of a disaster.The disaster power supply device for ships of the present invention is connected to the main battery of a small boat to charge surplus power and use it as a power source in the event of a disaster.The disaster power supply device for ships of the present invention has a disaster battery that charges surplus power from the power supplied from the outboard motor to the main battery, an isolator that is connected to the main battery and switches charging to the disaster battery when the main battery is fully charged, an outlet that is connected to the disaster battery via the isolator and enables the power charged in the disaster battery to be supplied to the outside, and a portable housing that incorporates the disaster battery, isolator, and outlet and is equipped with a handle for carrying.

[0013] Furthermore, as one aspect of the present invention, in order to solve the problem of preventing failure of the isolator due to water intrusion, the portable housing may have a built-in installation stand for installing the isolator at a predetermined height or higher from the installation surface of the portable housing.

[0014] Furthermore, as one aspect of the present invention, in order to solve the problem of increasing convenience as an emergency power source, the outlet may be constituted by a cigarette lighter socket provided on the front side wall of the portable housing.

[0015] Furthermore, as one aspect of the present invention, in order to solve the problem of preventing an electrical short circuit due to flooding, the installation height of the isolator and the outlet and the height of the connection terminal of the disaster battery may be configured to be 10 cm or more above the installation surface of the portable housing.

[0016] Furthermore, as one aspect of the present invention, in order to solve the problem of facilitating start / stop operations in situations where operation is difficult, such as when the operator is wearing rubber gloves, the portable housing may have a toggle switch provided on the front side wall, and a switch operation transmission mechanism that transmits the up and down movement of the toggle switch via a link mechanism to a rocker switch that starts and stops the isolator.

[0017] Furthermore, as one aspect of the present invention, in order to solve the problem of facilitating the handling of the connection cable connecting the isolator and the main battery, a cable insertion hole may be opened in the rear side wall portion of the portable housing, through which the connection cable connecting the isolator and the main battery can be inserted.

[0018] Furthermore, as one aspect of the present invention, in order to solve the problem of making it easy to remove the disaster battery for standalone use, the charging cable connecting the disaster battery and the isolator may be equipped with a detachable VL connector. [Effects of the Invention]

[0019] According to the present invention, surplus electricity generated by an outboard motor can be stored without interfering with the operation of a small boat, and in the event of a disaster, the battery can be carried to an evacuation site or the like and used as an emergency power source.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a marine emergency power supply device according to the present invention will now be described with reference to the accompanying drawings.

[0022] The marine emergency power supply device 1 of this embodiment is connected to the main battery 100 of a small boat to charge excess power and be used as a power source in the event of a disaster, and as shown in Figures 1 to 3, it comprises a disaster battery 2 that charges the excess power, an isolator 3 that switches the charging destination based on the charge state of the main battery 100, an outlet 4 that enables the power charged in the disaster battery 2 to be supplied to the outside, and a portable housing 5 that houses the disaster battery 2, the isolator 3, and the outlet 4. Each component will be described in detail below.

[0023] The disaster battery 2 is a battery that generates electricity by the outboard motor 300 of the small boat, and is used to charge the surplus electricity that cannot be stored when the main battery 100 is fully charged, and functions as an emergency power source in the event of a disaster.In this embodiment, a commercially available 12V (volt) battery is used.

[0024] 1 and 2, the disaster battery 2 is formed in a box shape, with a positive connection terminal 21a and a negative connection terminal 21b disposed on the top surface. In addition, the disaster battery 2 is installed in a portable housing 5 and is positioned at a height of 10 cm or more above the installation surface 200 of the portable housing 5, as shown in FIG. 4, so that when water seeps into the battery room (not shown) of the small boat on which the marine disaster power supply device 1 is installed, the water will not come into contact with the connection terminals 21 and cause an electrical short circuit.

[0025] The emergency battery 2 is not limited to a 12V battery, but may be a 24V battery or any other battery capable of charging electricity generated by the outboard motor 300.

[0026] The isolator 3 is a device that mainly switches the charging destination to the disaster battery 2 when the main battery 100 becomes fully charged, and in this embodiment, as shown in Figures 4 and 5, on the front side, there is a rocker switch 31 that starts and stops the marine disaster power supply device 1, and five connection terminals 32 arranged in a horizontal row. As shown in Figure 3, the connection terminals 32 are arranged in the order of positive terminal 32a, negative terminal 32b, negative terminal 32c, positive terminal 32d, and positive terminal 32e from left to right.

[0027] The positive and negative poles 32a and 32b arranged first and second from the left are connected to the positive pole 101a and negative pole 101b, respectively, of the connection terminal 101 of the main battery 100, as shown in Fig. 3. The main battery 100 side of the connection cable 55 that connects the isolator 3 and the main battery 100 is configured with an alligator clip (not shown), which can be easily connected by gripping it onto the connection terminal 101 of the main battery 100.

[0028] Furthermore, the negative pole 32c arranged third from the left is connected to the negative pole 41b of the connection terminal 41 of the emergency battery 2 and the outlet 4, and the second negative pole 32b and the third negative pole 32c from the left are connected inside the isolator 3. Therefore, the negative poles 21b, 41b of the emergency battery 2 and the outlet 4 are connected to the negative pole 100b of the main battery 100.

[0029] The positive terminal 32d, which is positioned fourth from the left, is connected to the positive terminal 21a of the disaster battery 2. The charging cable 7, which connects the positive terminal 32d, which is positioned fourth from the left of the isolator 3, to the positive terminal 21a of the disaster battery 2, is provided with a fuse 6 to prevent the disaster battery 2 from breaking down due to an overcurrent.

[0030] In addition, in order to enable the disaster battery 2 to be removed from the ship disaster power supply device 1 in the event of a disaster and used as a standalone power source, a VL connector 71 is provided in the middle of the charging cable 7 connecting the isolator 3 to the disaster battery 2, and the disaster battery 2 is configured to be easily detached.

[0031] The positive pole 32e, which is located fifth from the left, is connected to the positive pole 41a of the connection terminal 41 of the outlet 4, and a fuse 6 is provided in the wiring connecting these to prevent the outlet 4 from breaking down due to overcurrent.

[0032] The isolator 3 is placed at a predetermined height on a mounting base 51 built into the portable housing 5. As shown in Figures 4 and 5, the mounting base 51 in this embodiment is formed in a substantially cubic shape with an opening on the front side. This opening allows wiring to be connected to the rocker switch 31 and each electrode terminal 32 of the isolator 3.

[0033] In addition, the bottom surface 52 of the installation stand 51 is formed at a height that prevents the isolator 3 from becoming submerged in water when water enters the battery compartment. In this embodiment, as shown in Figure 4, the height is 10 cm or more from the installation surface 200 of the portable housing 5, similar to the height of the electrodes 21 of the disaster battery 2.

[0034] The number of connection terminals 32 of the isolator 3 is not limited to five, and may be appropriately selected from among those having a number of connection terminals 32 that allows switching between charging the main battery 100 and the disaster battery 2 and supplying power from the disaster battery 2 to the outlet 4.

[0035] The outlet 4 is for supplying the power charged in the disaster battery 2, and in this embodiment is constituted by a cigarette lighter socket 42, with the socket opening in the front side wall of the portable housing 5 so that power can be supplied to the outside of the portable housing 5.

[0036] This outlet 4, like the connection terminal 21 of the disaster battery 2 and the isolator 3, is installed at a height of 10 cm or more above the installation surface 200 of the portable housing 5 so that the outlet 4 will not be submerged in water if water enters the battery compartment.

[0037] The outlet 4 is not limited to the cigarette lighter socket 42, but may be a USB port or a power outlet, and may include a voltage converter, etc., as needed.

[0038] The portable housing 5 is a housing that houses the emergency battery 2, isolator 3, and outlet 4, and in this embodiment, as shown in Figures 1 and 2, is a container formed in a substantially three-dimensional shape with a lid on the top surface. The bottom surface of the portable housing 5 is formed in a convex shape, and the top surface of the lid is formed in a concave shape so that it can be fitted into the bottom surface, and is configured so that the two can be installed one above the other.

[0039] The portable housing 5 also has handles 53 for easy portability, and in this embodiment, these handles are two U-shaped handles 53, 53, as shown in Figures 1 and 2. The handles 53 are arranged parallel to each other in the front-to-rear direction, and the left and right ends of each handle are pivotally supported on both the left and right side surfaces of the portable housing 5 so that they can swing freely in the front-to-rear direction.

[0040] Additionally, a toggle switch 8 and a switch operation transmission mechanism 9 are provided on the front side wall of the portable housing 5 for starting and stopping the isolator 3 from outside the portable housing 5. The toggle switch 8 is a switch mechanism that can be turned on and off by tilting a lever. In this embodiment, the toggle switch 8 is used so that it can be easily operated while wearing rubber gloves or the like.

[0041] The switch operation transmission mechanism 9 is a mechanism for transmitting the on / off operation of the toggle switch 8 to the rocker switch 31, which starts and stops the isolator 3. In this embodiment, as shown in Fig. 6, the switch operation transmission mechanism 9 is composed of a toggle-side link 91 that tilts forward and backward in conjunction with the up and down movement of the toggle switch 8, a rocker-side link 92 that tilts forward and backward in conjunction with the rocker switch 31, an upper link 93 that connects the upper end of the toggle-side link 91 to the upper end of the rocker-side link 92, and a lower link 94 that connects the lower end of the toggle-side link 91 to the lower end of the rocker-side link 92, and by the same movement as a parallel link mechanism, the movement of flipping the toggle switch 8 up and down is converted into the up and down movement of the rocker switch 31 by each link.

[0042] 2, a cable insertion hole 54 is formed in the rear side wall of the portable housing 5, through which a connection cable 55 that connects the isolator 3 and the main battery 100 is inserted. This makes it easy to route the connection cable 55 when connecting the marine disaster power supply device 1 to the main battery 100, and facilitates installation in a small battery room.

[0043] In this embodiment, the portable housing 5 is formed in a shape in which the dimension in the left-right direction is longer than the dimension in the front-to-back direction, but it may be formed in a shape in which the dimension in the front-to-back direction is longer, or it may be formed in a shape in which the length dimensions in the front-to-back and left-to-right directions are the same.

[0044] Next, the operation of each component of the marine emergency power supply device 1 of this embodiment will be described.

[0045] First, the marine emergency power supply device 1 of this embodiment is connected to the main battery 100 connected to the outboard motor 300 of the small boat. Specifically, the portable housing 5 is installed in the battery room of the small boat in which the main battery 100 is stored, with the back side of the portable housing 5 facing the main battery 100. In this embodiment, the portable housing 5 is provided with a handle 53, making it easy to carry and allowing anyone to easily install it.

[0046] Next, the connection cable 55 is connected to the main battery 100. A cable insertion hole 54 for inserting the connection cable 55 is opened in the rear side wall, making it easy to route the connection cable 55 to the main battery 100. The connection cable 55 also has an alligator clip at its tip, and by clamping this alligator clip to the electrode 101 of the main battery 100, the marine disaster power supply device 1 and the main battery 100 can be easily connected.

[0047] Next, the connected marine disaster power supply device 1 is started. Specifically, the toggle switch 8 provided on the front side wall of the portable housing 5 is lifted from bottom to top. This causes the upper end of the toggle side link 91 to fall toward the isolator 3, the upper link 93 to move toward the isolator 3, and the lower link 94 to move toward the toggle switch 8. As the upper link 93 and lower link 94 move forward and backward, the upper side of the rocker side link 92 falls toward the isolator 3, and the rocker switch 31 of the isolator 3 connected to the rocker side link 92 can be turned on.

[0048] In this way, the marine disaster power supply device 1 can be started by operating a switch on the outside front of the portable housing 5, so the start-up operation can be performed with the lid of the portable housing 5 closed, preventing water from entering the housing while operating the switch. Also, since the switch can be operated by simply tilting the toggle switch 8 up and down, it can be easily operated even while wearing rubber gloves.

[0049] When the marine emergency power supply system 1 is started, the isolator 3 begins to determine whether the main battery 100 is fully charged. If it is determined that the main battery 100 is not fully charged, the isolator 3 continues charging the main battery 100.

[0050] On the other hand, if the isolator 3 determines that the main battery 100 is fully charged, the outboard motor 300 switches the charging destination to the emergency battery 2. As a result, the emergency battery 2 charges the surplus power that is no longer being charged to the main battery 100.

[0051] If the isolator 3 determines that the main battery 100 is not fully charged while the emergency battery 2 is being charged, it switches the charging destination to the main battery 100. In this way, the isolator 3 switches the charging destination as appropriate while determining the charge state of the main battery 100. This ensures that the main battery 100 is always kept sufficiently charged, allowing surplus power to be charged to the emergency battery 2 without interfering with the operation of the small boat.

[0052] Furthermore, when a small boat is operating, it may be hit by waves, and water may flood the boat along with the nets and fish. In this regard, because the isolator 3 is installed on the installation stand 51 inside the portable housing 5, breakdowns due to flooding and the like can be prevented. Furthermore, in this embodiment, the isolator 3, the outlet 4, and the connection terminals 21 of the emergency battery 2 are configured to be at least 10 cm above the installation surface 200 of the portable housing 5. Therefore, based on experience, even if flooding occurs, the water depth will not reach the height of the current-carrying vessel, preventing overcurrent due to an electrical short circuit and breakdowns of each device.

[0053] In the event of a power outage due to a disaster or the like, the marine vessel disaster power supply device 1 is used as an emergency power source. First, the marine vessel disaster power supply device 1 is removed from the main battery 100. Specifically, the alligator clip of the connection cable 55 that is clamped to the electrode 101 of the main battery 100 is removed. This disconnects the marine vessel disaster power supply device 1 from the main battery 100. In this embodiment, the portable housing 5 is provided with a handle 53, making it portable and allowing it to be freely carried to an evacuation site or the like.

[0054] Power is supplied via the outlet 4. In this embodiment, since it is configured with a cigarette lighter socket 42, various commercially available electronic devices, such as USB chargers, refrigerators, and electric blankets that are compatible with the cigarette lighter socket 42, can be used. It is also possible to charge mobile communication devices, operate televisions and radios, and collect and transmit information, providing relief and safety to disaster victims.

[0055] Furthermore, in this embodiment, a VL connector 71 is provided on the charging cable 7 that connects the disaster battery 2 to the isolator 3, allowing the disaster battery 2 to be easily detached from the isolator 3. This makes it possible to carry only the disaster battery 2 in the event of a disaster, reducing the burden of carrying it. When the disaster battery 2 of another marine disaster power supply device 1 runs out of charge, it can be replaced with another disaster battery 2, allowing it to continue to be used as a power source in the event of a disaster.

[0056] After the power outage ends, the marine vessel disaster power supply device 1 can be connected to the small vessel's main battery 100 to recharge surplus power again, allowing it to be used repeatedly as a power source in the event of a disaster.

[0057] According to the marine emergency power supply device 1 of this embodiment as described above, the following effects can be achieved. 1. Surplus electricity from small boats can be charged and used as a power source in the event of a disaster. 2. The portable housing 5 is provided with a handle 53, so that it can be easily placed in a battery room or carried to an evacuation site or the like. 3. Since the disaster battery 2, isolator 3 and outlet 4 are built into the portable housing 5, water will not get on these disaster battery 2, isolator 3 and outlet 4 while the small vessel is operating, preventing malfunction due to submersion in water, etc. 4. The installation base 51 is installed at a position higher than the water depth when the isolator 3 is flooded, so that damage to the isolator 3 due to flooding can be prevented. 5. The conductive parts of the disaster battery 2, isolator 3 and outlet 4 are configured to be at a height of 10 cm or more above the installation surface 200 of the portable housing 5, which exceeds the maximum water depth in the event of flooding, so that even if the device is flooded, it will not cause an electrical short circuit and will be able to maintain its charging and power supply functions. 6. The ship disaster power supply device 1 can be started and stopped from outside the portable housing 5, and by using a toggle switch 8 as the switch, it can be easily started and stopped even in an environment where rubber gloves or the like are worn on the hands, as is expected on small ships. 7. By converting outlet 4 into cigarette lighter socket 42, it is possible to supply power to a variety of commercially available products, making it highly versatile. 8. By providing a VL connector 71 on the charging cable 7 connecting the disaster battery 2 and the isolator 3, the disaster battery 2 can be easily attached and detached, allowing the disaster battery 2 to be carried alone and easily replaced with a disaster battery 2 that has run out of charge.

[0058] The marine emergency power supply device according to the present invention is not limited to the above-described embodiment and can be modified as appropriate. For example, the main battery 100 side of the connection cable 55 that connects the isolator 3 and the main battery 100 is not limited to an alligator clip, and may be selected from round terminals, U-shaped terminals, etc. as appropriate.
