Description

Technical Field

[0001] This invention relates to the fields of renewable energy and power generation technology, and in particular to a longitudinally rotating marine turbine power generation hydrogen production device. Background Technology

[0002] Hydrogen has long been considered a clean fuel. Especially for industries that struggle to decarbonize, such as manufacturing, aviation, and shipping, hydrogen energy is seen as a potential solution to critical energy challenges.

[0003] However, almost all of the world's hydrogen is currently extracted from fossil fuels, resulting in the emission of approximately 830 million tons of carbon dioxide annually.

[0004] With the progress of the times, the development and utilization of hydrogen energy is an inevitable trend towards cleaner energy. Hydrogen energy is a key link in the construction of my country's diversified energy system. If we can utilize the characteristics of the ocean to convert potential energy and tidal energy into electrical energy, and then use this electrical energy to produce hydrogen, this would undoubtedly be a new way and attempt to produce hydrogen, which is of great significance to the development of the hydrogen energy industry. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a longitudinal marine turbine power generation and hydrogen production device, which utilizes the turbine to rotate under the action of horizontal and vertical forces of seawater to achieve the purpose of power generation, and uses it to electrolyze seawater, separate and purify the electrolysis products, and store and utilize the separated hydrogen and other products separately, while the surplus electrical energy is also stored or utilized.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] This longitudinal marine turbine power generation and hydrogen production device includes an external track, a main turbine, a first power generation mechanism, and a post-processing device;

[0008] The external track includes a frame structure for mounting the main rotating wheel. The frame structure is fixedly provided with an upper fixed bushing and a lower fixed bushing according to the upper and lower corresponding relationship. The upper fixed bushing is provided with a suspension ring structure along the circumferential direction to keep the entire power generation and hydrogen production device horizontally suspended on the sea surface.

[0009] The main rotor includes an inner shaft, an impeller assembly, an electrolysis device, a vacuum pump, and a pressure sensor. The upper part of the inner shaft is rotatably connected to the inner ring of the upper fixed bushing of the outer track, and the lower end of the inner shaft is rotatably connected to the inner ring of the lower fixed bushing. The central ring of the impeller assembly is sleeved and fixed in the middle of the inner shaft, and the rotation of the rotor can drive the inner shaft to rotate. The pressure sensor is located below the impeller assembly and is used to transmit real-time pressure values ​​to an external remote control mechanism. The electrolysis device and the vacuum pump are located above the impeller assembly. The outlet of the electrolysis device is connected to an air bag, and the air bag is connected to the vacuum pump through an air pipe.

[0010] The first power generation mechanism includes a first generator, the rotor of which is connected to the upper end of the inner shaft of the main rotor. The generator generates electricity through the rotation of the impeller device. The generated electricity is stored and distributed through a post-processing device, and the distribution is used to power at least the electrical components of the hydrogen production and power generation device.

[0011] Furthermore, the device also includes a second power generation mechanism, which includes a second generator, an auxiliary rotor, and a differential amplifier. The auxiliary rotor is detachably sleeved on the outside of the lower fixed bushing of the outer track. When the auxiliary rotor rotates, it also drives the frame structure where the lower fixed bushing is located to rotate. The differential amplifier adopts a planetary gear transmission system and is drivenly connected to the upper fixed bushing of the frame structure. The rotor of the second generator is drivenly connected to the gear part of the speed amplifier. Power is generated by the rotation of the auxiliary rotor, and the obtained power is stored and distributed through a post-processing device.

[0012] Furthermore, the blades of the impeller device adopt a variable tilt angle design, and the connection between each blade and the central ring adopts a rotatable movable structure;

[0013] Furthermore, the entire impeller assembly is protected by a detachable protective cover;

[0014] Furthermore, at least one cylindrical support is provided inside the protective cover, which is used to surround the upper end and / or lower end of the central ring of the impeller device;

[0015] Furthermore, the outer ring of the protective cover is uniformly equipped with water spraying and absorption assist devices, which are controlled by an external remote control mechanism and are used to absorb seawater and spray water in the opposite direction during the rotation of the wheel.

[0016] Furthermore, the blade rotation angle is 60°.

[0017] The beneficial effects of this invention are: this device uses seawater as raw material, and generates electricity by driving the device through seawater, converting potential energy and tidal energy into electrical energy. This electrical energy is then used as an energy supply to electrolyze seawater, thereby generating products such as hydrogen, oxygen, and chlorine, which are then recycled. The overall production process is safe and will not cause pollution or damage to the environment, which is in line with the concept of green and environmentally friendly development. At the same time, the overall manufacturing cost is low, making it suitable for widespread application.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides a longitudinal marine turbine power generation and hydrogen production device, which includes an external track 1, a main turbine 2, a first power generation mechanism, and a post-processing device 4;

[0037] The external track 1 includes a frame structure 11 for mounting the main rotating wheel. The frame structure is fixedly provided with an upper fixed bushing 12 and a lower fixed bushing 13 in a corresponding relationship. The upper fixed bushing is provided with a suspension ring structure 14 in the circumferential direction to keep the entire power generation and hydrogen production device horizontally suspended on the sea surface. In this embodiment, the suspension ring structure is made of rubber material with a structural material density less than water and is corrosion-resistant and wear-resistant.

[0038] The main rotor 2 includes an inner shaft 21, an impeller device 22, an electrolysis device 23, a vacuum pump 24, and a pressure sensor 25. The upper part of the inner shaft is rotatably connected to the inner ring of the upper fixed bushing of the outer track through a bearing, and the lower end of the inner shaft is rotatably connected to the inner ring of the lower fixed bushing through a bearing. The central ring 221 of the impeller device 22 is sleeved and fixed in the middle of the inner shaft (it can be fixed by a convex ring and through groove, or by other connection methods). When the rotor rotates, it can drive the inner shaft to rotate.

[0039] The pressure sensor 25 is located below the impeller and is used to transmit real-time pressure values ​​to an external remote control mechanism. Combined with automation technology, the pressure sensor parameters can be remotely detected and controlled to correct problems and other abnormal conditions.

[0040] Electrolysis device 23 and vacuum pump 24 are located above the impeller. The outlet of electrolysis device 23 is connected to an air bag, which is connected to the vacuum pump through an air pipe. In this embodiment, the air bag is shaped like a swimming ring and is a circular air bag fixed to a ring on the surface of the lower half of the protective cover of the main rotor to ensure that the buoyancy generated when the air bag expands is relatively evenly distributed on the buoyancy of the entire main rotor.

[0041] In this embodiment, the first power generation mechanism includes a first generator 3. The rotor of the first generator 3 is connected to the upper end of the inner shaft of the main rotor. It generates electricity through the rotation of the impeller device. The obtained electricity is stored and distributed through the post-processing device 6. The distribution is at least used for power generation and hydrogen production devices. The power components include the aforementioned electrolysis device, pump and pressure sensor.

[0042] As a further improvement, in this embodiment, the entire impeller assembly is protected by a detachable protective cover 26. The entire impeller assembly is enclosed by the upper and lower protective covers connected by fasteners. Columnar supports 27 are also provided inside the protective cover near the upper and lower ends of the central ring of the impeller assembly, surrounding the upper and lower ends of the central ring to ensure that the plane of the impeller assembly is perpendicular to the inner shaft, preventing the impeller from tilting.

[0043] As a further improvement, the pressure sensor can be located in the lower half of the protective cover, while the electrolysis mechanism and the vacuum pump can be located in the upper half of the protective cover, thus facilitating wiring and installation.

[0044] As a further improvement, water spraying and absorption assist devices are evenly installed around the outer ring of the protective cover. These devices are controlled by an external remote control mechanism and are used to absorb seawater and spray it in the opposite direction during the rotation of the main rotor, thereby reducing the movement resistance of the main rotor. The device structure and technical means of the "remote control mechanism," "power generation mechanism," and "electrolysis device" described in this invention are existing conventional technologies, and there are no technical obstacles for those skilled in the art. Therefore, their specific structures will not be described in detail here.

[0045] Example 2

[0046] like Figure 3 , Figure 4 and Figure 5As shown, based on Embodiment 1, in this embodiment, the blades of the impeller device adopt a variable tilt angle design. In this embodiment, each blade and the central ring are connected by a rotatable movable structure. Specifically, the central ring 221 is a double-layer structure. The outer ring surface is uniformly provided with multiple butterfly-shaped slots 223. The tail end of the blade 222 is inserted vertically into the slot corresponding to the length of the slot, and the tail end is fitted with an upper limit to prevent it from slipping out of the slot. In this embodiment, the blade rotation angle is limited to 0°-60° by the design of the slot angle. During the two working processes of the impeller rising and falling, in order to keep the force direction always in the direction that makes the blade rotate in the same direction (counterclockwise), when the vertical movement direction of the impeller changes, the designed variable angle blade structure can autonomously switch the angle under the action of water flow.

[0047] Example 3

[0048] like Figures 6 to 9 As shown, this embodiment, based on Embodiment 1 and / or Embodiment 2, further includes a second power generation mechanism 5. The second power generation mechanism includes a second generator 51, an auxiliary wheel 52, and a differential amplifier 53. The auxiliary wheel is detachably sleeved onto the outside of the lower fixed bushing of the outer track (in this embodiment, protrusions are set on both sides of the wheel center ring, which are engaged with the corresponding through grooves on the outer side of the outer shaft for fixation; other structures can also be used). When the auxiliary wheel 52 rotates, it also drives the frame structure where the lower fixed bushing is located to rotate. The differential amplifier 53 adopts a planetary gear transmission system, which consists of four gears in this embodiment. It amplifies the angular velocity and is connected to the upper fixed bushing of the frame structure through a hard metal rod. The rotor of the second generator 51 is connected to the gear part of the speed amplifier. Power is generated by the rotation of the auxiliary wheel, and the obtained power is stored and distributed through the post-processing device 6.

[0049] Figure 10 This is a schematic diagram of the overall structure of the present invention.

[0050] Example 4

[0051] like Figure 11 As shown, this embodiment adds a protective cage 6 to the overall structure to protect the impeller device 22, auxiliary wheel 52, frame structure 11 and part of the inner shaft 21, thereby further improving the protection effect of key components and extending the service life of the device.

[0052] As a further improvement, in this embodiment, a counterweight structure 7 is installed at the bottom of the protective cage 6 to help control the external track device to maintain an upright state as much as possible, so as to prevent the track from shifting or overturning due to extreme weather conditions (of course, the device can be shut down or sealed off for protection in extremely severe weather).

[0053] This invention utilizes the rotation of the main rotor under the action of horizontal and vertical forces from seawater to generate electricity. The obtained electrical energy is used to electrolyze seawater, and the electrolysis products are separated and purified. The separated products, such as hydrogen, are stored and utilized separately, and any surplus electrical energy is also stored or utilized.

[0054] Based on the above embodiments, the working principle of the present invention is as follows: Due to gravity (gravitational potential energy), the main impeller moves downwards along the inner shaft. Seawater flows vertically through the gaps between the blades, and the blades are subjected to lateral pressure from the seawater. The impeller rotates, driving the inner shaft to rotate. The upper end of the inner shaft drives the rotor of the first generator to rotate, thus generating electricity. When the impeller descends to the bottom of the inner shaft, the pressure sensor senses the impeller's position and sends a signal. An external control mechanism then controls the electrolyzer to start working, electrolyzing seawater to produce gas. The gas bag expands, gradually increasing its volume and buoyancy. When the buoyancy of the main impeller exceeds its weight, it drives the main impeller upwards. During this movement, the seawater flowing through the blades exerts a force on the blades again, causing them to rotate, which in turn drives the inner shaft and the rotor of the first generator to rotate, thus generating electricity. When the rotor rises to near the sea surface, the pressure sensor detects that its position is at the highest point of the track and sends a signal. The external control mechanism triggers the air pump to extract the gas from the air bag. The air bag shrinks in volume, reducing buoyancy. When the weight of the main rotor is greater than the buoyancy, it continues to move downwards. Under the force generated by the flowing seawater, it rotates, driving the rotor of the first generator to rotate, thus realizing the cyclical generation of electrical energy.

[0055] The extracted gas undergoes chemical steps such as separation and purification. Hydrogen is separated, purified, and stored, while other products are separated and stored separately.

[0056] As a further improvement, a water spraying and suction assist device 26 is installed on the outer ring of the rotor protective cover. Under the control of the system, it absorbs seawater and sprays water in the opposite direction during the rotor's movement to reduce the movement resistance of the main rotor.

[0057] The blades of the auxiliary rotor nested on the shaft rotate as the seawater flows laterally, causing the lower fixed shaft sleeve to rotate. Because the upper and lower fixed shaft sleeves are rigidly connected by a frame structure, the upper fixed shaft also rotates. The angular velocity is amplified by a speed amplifier composed of planetary gear sets. The upper end of the speed amplifier is connected to the rotor of the second generator via a sleeve, thereby driving this generator to generate electricity. The electrical energy generated by the two generators is uniformly stored and distributed by a post-processing device. A portion is used by the internal working system, and excess energy can be supplied externally. In practical applications, the initial startup process can be powered by an external battery. Once both rotors are in normal working condition, the electrical energy required by the electrolysis and other devices is obtained from the generators.

[0058] The device of this invention generates electricity to supply gas produced by electrolyzing seawater. Driven by buoyancy, the rotor rises to near the sea surface, collects and utilizes the gas, and then vents it before being driven by gravity. The generation and venting of gas enable buoyancy and descent, generating electricity vertically. This allows for continuous, cyclical operation, forming an indispensable closed loop. It constitutes a self-sufficient, closed-loop system that meets its own needs while generating substantial amounts of electricity, achieving both self-production and external supply requirements.

[0059] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
