Description

[Technical field]

[0001] The present invention relates to a ship equipped with a power generating device that generates useful power from the motion of the ship caused by waves and wind. [Background technology]

[0002] A typical power generating device converts energy obtained mainly from fossil fuels or nuclear power, or renewable energy, into useful power and uses it. In light of recent global environmental issues, there is a widespread demand for further energy saving and high efficiency, and at the same time, there are high expectations for a power generating device that can provide a stable supply of renewable energy. There is a demand for a power generating device that effectively utilizes the reciprocating up and down motion obtained by such forces such as nature.

[0003] The applicant has previously proposed a power generating device described in Patent Document 1. This invention relates to a power generating device characterized by comprising opposing pillars that support the power generating device, one or more movable inclining members that have an inclination from one pillar side to the other pillar side in order to rotate a rotating member, and that can rise and fall along the pillars by one or more roller members at both ends and roller receiving members provided on the pillars, and one or more fixed inclining members that have an inclination from the other pillar side to one pillar side in order to rotate the rotating member, and that are provided on the pillars or support members that support the pillars.

[0004] According to the invention described in Patent Document 1, it is possible to provide an energy-saving power generating device that generates power by moving a movable inclined member up and down to rotate a rotating member. In particular, the generated power can be used even in areas or places where electricity is not supplied, without using a power source.

[0005] One application of such a power generating device is to generate power by installing it on the sea and using the up and down motion caused by waves. The applicant of the present application has also conducted extensive research into other applications and discovered that the power generating device can be used by using the motion inside a ship.

[Figure 4] FIG. 4 is a schematic diagram showing another configuration of a ship equipped with a power generating device according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The ship equipped with the power generating device according to the present invention will be described in detail below. Note that the present invention is not limited to the following examples, and can be modified as desired without departing from the gist of the present invention.

[0014] 1 is a schematic diagram showing the configuration of a ship equipped with a power generating device according to one embodiment of the present invention. One aspect of the present invention is a ship equipped with a power generating device 10 that generates useful power from the rocking of the ship caused by waves and wind, characterized in that a hull having a ballast tank 11 has an installation room 12 for a power generating device 20 provided in the ballast tank 11, and the installation room 12 is filled with an amount of liquid capable of floating the power generating device 20, and the power generating device 20 generates power by utilizing the up and down movement of the liquid in the installation room 12 in response to the rocking of the ship caused by waves and wind.

[0015] In ships, particularly cargo ships such as tankers, the degree to which the ship floats or sinks (draft) changes depending on the weight of the cargo carried. In particular, when no cargo is loaded, the ship's buoyancy prevails and less of the ship is submerged in the sea, making it difficult to navigate stably. For this reason, ships are provided with spaces called ballast tanks, and when the ship is carrying a small amount of cargo, seawater is taken in to increase the weight and adjust the draft. In this invention, a portion of the space in the ballast tank is used to generate power.

[0016] The installation room 12 in the power generating unit-equipped ship 10 can be provided, for example, by separating a part of the ballast tank 11 with a bulkhead. Alternatively, a room-like space such as a container may be installed in the ballast tank 11 or may replace a part of the ballast tank 11. Also, a liquid capable of floating the power generating unit 20 is poured into the installation room 12. The liquid is, for example, water, but a part of the seawater poured into the ballast tank 11 may be used. Alternatively, a liquid with a high specific gravity may be filled in order to increase the buoyancy generated by the power generating unit 20.

[0017] In the present invention, the power generating unit 20 generates power by utilizing the up and down movement of the liquid in the installation room in response to the rocking of the ship caused by waves and wind. Therefore, the installation room 12 is provided with a space necessary for the power generating unit 20 to move up and down while floating on the liquid. To provide such a space, for example, it is sufficient to calculate the height and the amount of liquid to be filled so that the power generating unit 20 does not come into contact with the ceiling even when the ship rocks significantly, based on the degree of rocking of the ship.

[0018] The power generating device 20 is not particularly limited as long as it is a device that generates power by moving up and down in response to changes in the liquid level of the liquid filled in the installation chamber 12. As an example, a power generating device equipped with various mechanisms used in wave power generation or tidal power generation can be used.

[0019] In addition, the present invention can utilize the power generating device described in Patent Document 1, which was previously proposed by the applicant. According to the invention described in Patent Document 1, a floating body or the like is used to move the movable tilting member up and down in response to changes in the level of the liquid filled in the installation chamber, thereby rotating the rotating member, thereby efficiently generating power. For example, the movement of the rotating member and the movable tilting member can be used as a power source for pushing up the piston of an actuator such as an installed cylinder, and can be converted into an operation of compressing and sending out the contents (air or liquid) in the cylinder. In the figures of the present application, the power generating device of the embodiment shown in FIG. 7 of Patent Document 1 is illustrated as an example, but the present invention is not limited to this embodiment.

[0020] 2(A) and (B) are schematic diagrams for explaining the operation of a power generating device in an installation chamber divided into two by a partition. In one embodiment of the present invention, a partition 15 through which liquid can move is provided in the installation chamber 12, and the power generating devices 20 can be installed on both sides of the partition 15. In one embodiment of the present invention, for example, as shown in Figs. 2(A) and (B), the partition 15 leaves a space so as not to separate the lower part of the installation chamber 12, thereby allowing the liquid in the installation chamber 12 to move to either of the two sections.

[0021] In this way, when the ship tilts to the left, as shown in FIG. 2(A), the liquid in the installation chamber 12 moves to the left section, and the liquid level h L rises, and the liquid level h in the right section rises. R falls (h L >h R Similarly, as shown in Figure 2(B), when the ship tilts to the right, the liquid in the installation chamber moves to the right section, and the liquid level h R rises, and the liquid level in the left section h L falls (h R >h L In this way, the force of the waves and wind that causes the ship's hull to sway from side to side as it moves forward is converted into the up and down movement of the liquid level in the installation chamber 12, and this up and down movement of the liquid level can be converted into useful power by the power generating device 20.

[0022] FIG. 3 is a schematic diagram showing another configuration of a ship equipped with a power generating device according to an embodiment of the present invention. In the present invention, as described above, the installation room 12 is divided into two by a bulkhead 15, so that two power generating devices 20 can be installed in one installation room 12. In one aspect of the present invention, a plurality of such installation rooms 12 may be installed in the ballast tank 11. For example, if two installation rooms 12 are provided, four power generating devices 20 can be installed, and if three installation rooms 12 are provided as shown in FIG. 3, six power generating devices 20 can be installed. By installing many power generating devices 20 in this way, it is possible to generate a lot of power by utilizing the rocking of the ship.

[0023] FIG. 4 is a schematic diagram showing another configuration of a ship equipped with a power generating device according to an embodiment of the present invention. In one aspect of the present invention, a plurality of installation chambers 12 may be provided in the ballast tank 11 at intervals, and a flow path 17 through which liquid can move may be provided between each of the installation chambers 12. The principle of vertically moving the power generating device 20 is the same as that shown in FIG. 2, but in the case of FIG. 4, the liquid does not move directly between the two sections, but moves between the two sections through the flow path 17. Note that, although the number of installation chambers 12 is two in FIG. 4, for example, an additional installation chamber 12 may be provided in the center of the ballast tank 11, and a flow path 17 may be provided to connect each of the three sections, or the number of installation chambers may be four or more.

[0024] By installing the installation rooms 12 at a distance from each other, for example, as shown in Fig. 4, each installation room 12 can be located closer to the side of the ship, so that the effect of the rolling of the ship can be greater on the power generating device 20 in the installation room 12. Furthermore, even if the space for installing the installation rooms 12 is limited due to the influence of the onboard space of the ship, etc., each installation room 12 can be installed at an appropriate position while being spaced apart.

[0025] As described above, according to the present invention, a ship equipped with a power generating device capable of efficiently generating power by utilizing the rocking of the ship can be realized.

[0026] Although one embodiment of the present invention and each example have been described in detail above, it will be readily apparent to those skilled in the art that many modifications are possible without substantially departing from the novel features and effects of the present invention. Therefore, all such modifications are intended to be included within the scope of the present invention.

[0027] For example, a term described at least once in the specification or drawings together with a different term having a broader or similar meaning may be replaced with the different term anywhere in the specification or drawings. In addition, the configuration of the ship equipped with the power generating device is not limited to the one described in the embodiment and each example of the present invention, and various modifications are possible.
