[Figure 8] This figure shows a cross-section of another embodiment. [Figure 9] This diagram shows aspects of other embodiments. [Figure 10] This is a diagram showing an example of an electrical circuit. [Modes for carrying out the invention]

[0033] The present invention relates to an electrolytic apparatus 100 for performing electrolysis of freshwater or seawater on or underwater using electricity generated at the site, in order to obtain gases such as hydrogen or liquids.

[0034] <Water> Here, "water" refers to the liquid present in the relevant locations, such as seas and lakes. The electrolytic apparatus 100 of the present invention can be used in the sea or in lakes and marshes, depending on the gas or liquid to be produced. Furthermore, the water may be subjected to physical or chemical treatment before electrolysis as needed.

[0035] <Floating component> The electrolytic device 100 is equipped with a buoyancy member. The buoyancy member is a component that allows the entire electrolytic device 100 to float when it is placed in water for operation. The buoyancy member has a specific gravity lighter than water, and is preferably made of a hard material. Furthermore, the buoyancy member is preferably wider than the area of ​​the upper opening of the cylindrical member, and is preferably installed so that it covers the entire upper opening when viewed from above. By configuring the buoyancy member to be wider than the upper opening, the buoyancy member acts as a bumper when the electrolytic device 100 is carried away by wind or waves, thereby preventing damage to the electrolytic device 100 when it collides with another object. The buoyancy member can also function as a storage section as described later. The buoyancy member may be a plate-shaped float 270 made of resin.

[0036] <Cylindrical part> The electrolytic device 100 includes a cylindrical section. The cylindrical section has an upper opening 201 at the top and a lower opening 203 at the bottom, and is arranged to be connected to the floating member. The overall configuration of the cylindrical section may be cylindrical or rectangular. Electrodes 292, which perform the electrolytic operation described later, are arranged in the cylindrical section. Water for electrolysis is introduced into the cylindrical section from the upper opening 201, and the electrolyzed water is discharged from the lower opening 203. The cylindrical section functions as the housing 200 of the electrolytic device 100.

[0037] The recovery and storage of gases and liquids produced by electrolysis can be carried out by appropriately referring to prior art. Preferably, the gas produced by electrolysis is stored in a storage section installed at the top of the cylindrical section. Furthermore, the cylindrical section may be equipped with a power generation device and an energy storage device, as described later.

[0038] <Water passage means> The electrolytic device 100 is equipped with a water passage means. The water passage means is for releasing excess water from the electrolytic device 100 to the outside and functions as a drainage device 210.

[0039] The water passage means is provided at the bottom of the electrolytic device 100. One form of the water passage means may be a hole provided at the bottom. By providing a hole at the bottom of the electrolytic device 100, the entire electrolytic device 100 is moved up and down by waves, and water can be discharged from inside the electrolytic device 100 without requiring a power source.

[0040] The means of water passage may be a check valve. By providing a check valve at the bottom of the electrolytic device 100, and configuring it so that the valve opens from the inside to the outside of the electrolytic device 100 but does not open from the outside to the inside, the entire electrolytic device 100 is moved up and down by waves, allowing water to be discharged from the inside of the electrolytic device 100 without requiring a power source, while at the same time preventing water from entering the inside of the electrolytic device 100 from the outside.

[0041] The means of water supply may be an electric pump. The electrolytic device 100 can be equipped with a power generator, or the electric pump can be driven by power supplied from an external source. The electric pump may be operated continuously, or it may be operated as appropriate based on the state of electrolysis.

[0042] The electric pump may be installed at the bottom of the electrolytic device 100 or at the top of the electrolytic device 100. By installing the electric pump at the bottom of the electrolytic device 100, the electric pump can always be kept submerged in water. By controlling the driving method and piping of the electric pump, water can be flowed from outside the electrolytic device 100 in the opposite direction to the normal electrolysis operation. By flowing water in the opposite direction to the normal electrolysis operation, foreign matter accumulated inside the electrolytic device 100 can be discharged to the outside.

[0043] <Storage Department> The electrolytic device 100 may be provided with a storage unit. The storage unit can store the gas or liquid generated by the electrolytic device 100. The storage unit may be composed of an airbag 220.

[0044] <Power generator> The electrolytic device 100 may be equipped with a power generation device. As the power generation device, power generation using solar panels 230 or power generation using tidal power can be employed. It is preferable to install the solar panels 230 on the upper part of the floating plate 270.

[0045] <Energy storage device> The electrolytic device 100 may be equipped with a power storage device. The power storage device may store electricity generated by the power generator, or it may be pre-charged before operating the electrolytic device 100, and the electrolytic device 100 may be operated using the stored electricity. The power storage device can be installed in an appropriate location on the electrolytic device 100.

[0046] <Communication equipment> The electrolytic device 100 may be equipped with a communication device. The communication device can communicate with the base station 300 or with other electrolytic devices 100. The communication device may be wired or wireless. When communicating wirelessly, it is preferable to install an antenna 240 on the upper part of the floating member.

[0047] <Control Unit 250> The control unit 250 controls the electrolytic device 100. The control unit 250 detects the status of sensors and each device installed in the electrolytic device 100 and controls the operation of each device.

[0048] <Embodiment> Figure 1 shows a side view of one embodiment of the electrolytic apparatus 100. Figure 2 shows a view of the electrolytic apparatus 100 from below. The electrolytic device 100 comprises a cylindrical housing 200. A drainage device 210 is provided at the bottom of the housing 200. The bottom of the housing 200 is configured to narrow in cross-section according to the size of the drainage device 210. The drainage device 210 has a drain port 212 at its bottom. The water supply means can function as the drainage device 210 of the electrolytic device 100.

[0049] A water intake port 205 may be provided on the upper side of the housing 200. The water intake port 205 is an opening for allowing water to enter the electrolytic device 100. The water level A410 indicates the position of the water level when the electrolytic device 100 is in operation. In Figure 1, it can be seen that the water intake port 205 is located in the water. It is preferable to provide a filter 280 at the water intake port 205. A fine mesh filter 280 can be selected as the filter 280.

[0050] When an electric pump is used in the drainage device 210, when the electric pump operates, water enters the electrolytic device 100 from the water intake 205 and is discharged from the drain outlet 212.

[0051] The upper part of the housing 200 is equipped with an airbag 220 that functions as a storage compartment. The airbag 220 is preferably made of a retractable structure or material. The airbag 220 is configured to function as a levitation member. A solar panel 230, which serves as a power generation device, is positioned on top of the airbag 220.

[0052] Figure 4 shows the state in which the gas generated by the electrolytic device 100 is stored in the storage unit. If the storage unit is an airbag 220, as gas is generated, the airbag 220 will inflate vertically, allowing the solar panel 230, control unit 250, and antenna 240, which are located above the airbag 220, to be positioned higher than the water surface A410. The increased height of the antenna 240 has the effect of widening the communication range. The increased height of the control unit 250 has the effect of suppressing damage from waves, driftwood, etc. Furthermore, the increased height of the solar panel 230 has the effect of increasing the amount of power generated because it reduces the impact of things that block sunlight.

[0053] As shown in Figure 2, it is preferable that the buoyancy member is larger than the airbag 220. If the buoyancy member is made of rigid material, even if driftwood or other debris floats by, the buoyancy member will function as a bumper and prevent damage to the airbag 220.

[0054] The size of the airbag 220 is preferably larger than that of the housing 200. The airbag 220 can function as a bumper, preventing damage to the housing 200 from driftwood, etc.

[0055] The electrode 292 is preferably positioned along the longitudinal direction of the housing 200. As shown in Figure 3, by aligning the longitudinal direction of the electrode 292 with the longitudinal direction of the housing 200, the flow of water within the housing 200 is improved, resulting in better electrolysis operation.

[0056] Here, the electrode 292 may be flat or rod-shaped. It can be appropriately selected depending on the gas or liquid being produced.

[0057] Figure 5 shows another example. The embodiment shown in Figure 5 has a water intake 205 located above the floating plate 270. Waves and wind generate water spray 430, which enters the electrolytic device 100 through the water intake 205. Since the water enters at a position higher than the water surface, the water spray 430 that enters is discharged to the outside through a drain port 212 located at the bottom of the electrolytic device 100 by its own weight, thus eliminating the need for a drainage device 210.

[0058] Figure 6 shows a side view of another embodiment. The embodiment shown in Figure 6 has an airbag 220 installed on top of the float plate 270. By installing the airbag 220 on top of the float plate 270, even if gas generated by the electrolytic device 100 accumulates in the airbag 220, the position of the float plate 270 relative to the water surface does not change, allowing the electrolysis to operate in a stable state.

[0059] Figure 7 shows a side view of another embodiment. Figure 8 shows a cross-sectional view of another embodiment. The embodiment shown in Figure 7 is an example in which a fine-mesh filter 280 to prevent foreign matter from entering the water intake 205 is not provided, and instead a fine-mesh filter 280 is provided inside the housing 200.

[0060] As can be seen from Figure 8, a fine-mesh filter 280 is provided above the electrolytic chamber 290 to filter out foreign matter. With this configuration, large foreign matter can be removed at the water intake 205, and any foreign matter that cannot be removed at the water intake 205 can be prevented from entering the electrolytic chamber 290 by the fine-mesh filter 280.

[0061] The fine-mesh filter 280 is configured to have a shape similar to that of the housing 200 when viewed from above. Even when foreign matter accumulates in the fine-mesh filter 280, the airbag 220 can be removed from the housing 200 and the filter 280 can be easily removed and installed from the top of the housing 200, thus facilitating maintenance.

[0062] Figure 9 shows a side view of another embodiment. The embodiment in Figure 9 is characterized by being connected to a base station 300 (not shown) by a connecting pipe 260. The connecting pipe 260 may be equipped with, for example, a power line for supplying power to the electrolytic device 100, or it may be configured to send the gas or liquid produced by the electrolytic device 100 to the base station 300.

[0063] By connecting the base 300 and the electrolytic device 100 with a connecting pipe 260, it becomes unnecessary to equip the electrolytic device 100 with a power generation device or storage unit, allowing the electrolytic device 100 to be manufactured at a low cost.

[0064] The electrolytic apparatus 100 may consist of multiple electrolytic apparatuses 100 connected by connecting tubes 260, allowing for the exchange of gases or liquids and electricity generated by the electrolytic apparatuses 100 with each other. This configuration has the effect of allowing the electrolytic apparatuses 100 to exchange power with each other and to make effective use of the storage space.

[0065] Figure 10 shows an example of an electrical circuit. The power generation device is connected to the energy storage device and the load. Preferably, the power stored in the energy storage device is equipped with a power conversion device that can change the voltage and other parameters as appropriate according to the load.

[0066] The loads include electric pumps, power for electrolysis, control devices, and communication devices. The power generation system may consist of multiple power generation systems of the same type, or it may consist of power generation systems of different types. For example, power may be generated using multiple solar panels 230, or it may consist of two types of power generation systems: solar panels 230 and tidal power generation.

[0067] The electrolytic device 100 can be equipped with GPS, and its location information can be transmitted to the base station 300, making it easier to retrieve the electrolytic device 100 based on this location information. Furthermore, the electrolytic device 100 may be equipped with a propulsion function such as a screw, enabling it to move autonomously.

[0068] The control device uses its propulsion function to move the electrolyzer 100 to a sunny location, enabling efficient power generation using the solar panels 230. It also uses its propulsion function to move the electrolyzer 100 back to base 300 to collect the gases and liquids produced. [Explanation of Symbols]
