Description

Technical Field

[0001] This invention belongs to the field of ocean current power generation technology, and in particular relates to a deep-sea submersible ocean current energy capture device. Background Technology

[0002] With the development of industrialization, the consumption of traditional fossil energy has put great pressure on the ecological environment. At the same time, in the face of resource reserves issues, the development of new energy sources has become an urgent issue. Ocean current energy, as a highly efficient and clean energy source, is more stable than wave energy and more efficient than wind energy.

[0003] In particular, there are significant challenges in providing shore power to instruments and equipment such as deep-sea buoys and underwater moorings. Therefore, it is necessary to develop a targeted on-site power generation-storage-power supply solution.

[0004] Currently, existing ocean current energy generation devices are mainly divided into two types: horizontal axis devices and vertical axis devices. Compared with horizontal axis devices, vertical axis devices have a much lower ocean current energy capture efficiency and poorer stability. In addition, the installation locations of previous ocean current energy generation devices were relatively arbitrary, and they did not utilize unidirectional and stable seasonal ocean currents. Furthermore, existing devices cannot utilize ocean currents with a wider range of flow velocities, and suffer from insufficient stability and power generation efficiency at low flow velocities. Summary of the Invention

[0005] In view of the shortcomings of existing ocean current energy generation devices, the present invention aims to provide a deep-sea submersible ocean current energy capture device to achieve efficient utilization of ocean current energy over a wide range of flow velocities.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a deep-sea submersible current energy capture device, comprising a top plate buoy, a current energy capture device, a stabilizing wing, a bottom plate energy storage system, a heave balancing mechanism, and an anchoring mechanism.

[0007] The top buoy is installed on top of the ocean current energy capture device, providing buoyancy for the entire device. The ocean current energy capture device captures ocean current energy and converts it into electrical energy. The stabilizing fins are installed on both sides of the ocean current energy capture device, ensuring its balance. The bottom plate energy storage system is installed at the bottom of the ocean current energy capture device, storing the electrical energy generated and also directly powering other devices requiring power. The heave balancing mechanism is installed at the bottom of the bottom plate energy storage system, ensuring vertical balance and reducing device vibration. The mooring mechanism surrounds the heave balancing mechanism, with its mounting end installed along the outer edge of the bottom plate energy storage system. This mooring mechanism provides tension to balance the forces acting on the entire device.

[0008] The ocean current energy capture device includes a fairing, a turbine, a transmission device, a speed increaser, and a generator. Floats are installed on both sides of the turbine to provide buoyancy to the ocean current energy capture device itself. A transmission device is installed at the rear of the turbine, with its front end connected to the turbine and its sides connected to the speed increaser to convert ocean current energy into mechanical energy. The speed increaser is connected to the generator, which converts the mechanical energy into electrical energy, thus realizing the conversion of ocean current energy into electrical energy.

[0009] The floats, speed increasers, and generators are all installed inside the catcher housings on both sides of the turbine.

[0010] The front end of the trap housing is provided with a flow guide slope, which is located on the turbine input side. The flow guide shroud is symmetrically hinged to the end of the flow guide slope. The flow guide shroud can be closed and opened, and is supported and fixed in position by a support frame to achieve different flow guiding effects and improve the capture efficiency of the ocean current energy trap.

[0011] Furthermore, one or more ocean current energy capture devices can be installed between the top plate pontoon and the bottom plate energy storage system. When multiple ocean current energy capture devices are installed, they are interconnected. Multiple ocean current energy capture devices can be assembled and disassembled to meet different needs.

[0012] Furthermore, the flow guide is designed in an arc shape, and when the flow guide is opened, the flow guide and the flow guide slope achieve two-stage flow guidance.

[0013] Furthermore, a connecting post is provided on the top of the capture device shell, and wing mounting openings are symmetrically provided on both sides of the capture device shell. The wing mounting openings are used to install balancing and stabilizing winglets. When multiple ocean current energy capture devices are installed between the top plate buoy and the bottom plate energy storage system, the connecting post is used for mutual assembly and fixation between the ocean current energy capture devices.

[0014] Furthermore, the heave balancing mechanism includes a heave plate, which is connected to the base plate energy storage system via a strut. The heave plate is triangular in shape, which can reduce fluid resistance. The heave plate provides resistance and gravity when the entire device swings up and down, thus lowering the center of gravity of the entire device and facilitating its stability.

[0015] Furthermore, the base plate energy storage system includes a battery, which is connected to the generator of the ocean current energy capture device via an electrical power transmission line. The electrical energy generated by the ocean current energy capture device is transmitted to the battery for storage via the electrical power transmission line.

[0016] Furthermore, the mooring mechanism includes an anchor assembly, which is connected to a built-in anchor winch at the edge of the base plate energy storage system via a steel cable, and is scalable.

[0017] Furthermore, four steel cables are provided.

[0018] Furthermore, the anchor assembly includes a buried holding anchor and a suction anchor. The steel cable on the upstream side is connected to the buried holding anchor, which provides horizontal tension to the entire device to counteract the impact force of the ocean current in the upstream direction. The other three steel cables in the other three directions are connected to the suction anchor, which provides horizontal and vertical tension to the entire device. The tension provided by the steel cables cancels out the resultant force of the buoyancy and gravity of the entire device, achieving the balance and stability of the overall device.

[0019] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0020] (1) This invention is designed for unidirectional seasonal ocean currents and is designed to capture unidirectional ocean current energy. It is highly targeted and has a high utilization rate of ocean current energy.

[0021] (2) The number of ocean current energy traps of the present invention can be added and removed according to actual needs and environmental conditions, and it has strong adaptability to various ocean current environments and a wide range of applications.

[0022] (3) The balance stabilizing wing and heave plate of the present invention can ensure the stability of the overall device. At the same time, the flow guide can accelerate the passing ocean current, and can be used even when the ocean current velocity is low, so as to achieve efficient capture of ocean current energy. In addition, the flow guide slope can help the flow guide to further accelerate the flow.

[0023] (4) The present invention uses anchor winches to extend and retract steel cables to achieve depth changes, and can also utilize the ocean currents with the highest current speed according to the actual environment.

[0024] (5) The present invention uses steel cables in four directions to moor the whole device. The buried holding anchor on the upstream side can provide horizontal tension to the whole device to counteract the upstream force of the ocean current. The suction anchors in the other three directions can provide vertical tension and part of the horizontal tension to balance the buoyancy and gravity of the whole device. The steel cables in the four directions can fully ensure the force balance of the device.

[0025] In summary, this invention captures ocean current energy through the turbine of an ocean current energy capture device, then converts it into electrical energy for storage in an energy storage system; buoyancy is provided by the top plate buoy and the floats inside the ocean current energy capture device, and the tension provided by the mooring mechanism and the device's own weight are used to achieve balance, thereby capturing the energy of the mid-to-upper layer ocean currents with higher flow velocities; based on the guiding effect of the equipped flow deflector, the turbine can be used for acceleration when the ocean current velocity is low; the installed stabilizing fins and heave plates ensure the stability of the device during operation; the number of ocean current energy capture devices can be increased or decreased according to actual needs, making it widely adaptable, easy to use, and simple in structure.

[0040] like Figure 4 and Figure 5 As shown, the ocean current energy capture device 2 includes a fairing 7, a turbine 8, a transmission 9, a speed increaser 10, and a generator 11.

[0041] The turbine 8 is equipped with floats 12 on both sides, which provide buoyancy for the ocean current energy capture device 2 itself. A transmission device 9 is installed at the rear of the turbine 8. The front end of the transmission device 9 is connected to the turbine 8, and the two sides of the transmission device 9 are connected to the speed increaser 10 to convert ocean current energy into mechanical energy. The speed increaser 10 is connected to the generator 11, which converts mechanical energy into electrical energy, thus realizing the conversion of ocean current energy into electrical energy.

[0042] The float 12, the speed increaser 10, and the generator 11 are all installed inside the capture housing on both sides of the turbine 8.

[0043] The front end of the capture device housing is provided with a flow guide slope, which is located on the input side of the turbine 8. The flow guide shroud 7 is symmetrically hinged to the end of the flow guide slope. The flow guide shroud 7 can be closed and opened, and is supported and fixed in position by the support frame 15 to achieve different flow guiding effects and improve the capture efficiency of the ocean current energy capture device 2.

[0044] The flow guide 7 has an arc-shaped design. When the flow guide 7 is opened, the flow guide 7 and the flow guide slope achieve two-stage flow guidance.

[0045] The top of the capture device housing is provided with a connecting post 13, and the two sides of the capture device housing are symmetrically provided with wing mounting openings 14. The connecting post 13 is used for assembling and fixing the ocean current energy capture devices 2 together, and the wing mounting openings 14 are used for installing the balancing and stabilizing wing 3.

[0046] Among them, such as Figure 7 As shown, the transmission device 9 includes a housing 27, in which a main bevel gear 24 is installed. The main bevel gear 24 is connected to the turbine 8 via a main drive shaft 25. A first bevel gear 26 and a second bevel gear 28 mesh on the main bevel gear 24, and they are driven at right angles. The first bevel gear 26 and the second bevel gear 28 are symmetrically arranged.

Bearings 30 are provided between the main drive shaft 25 and the driven drive shaft 29 and the housing 27.

[0047] Among them, such as Figure 8 As shown, the support frame 15 includes a rod 31 and a C-shaped steel frame 32. The rod 31 and the C-shaped steel frame 32 are hinged together by a connecting pin 33. A fixing frame 34 is hinged to the end of the rod 31, and the rod 31 is connected to the flow guide 7 through the fixing frame 34. A fixing frame 34 is hinged to the end of the C-shaped steel frame 32, and the C-shaped steel frame 32 is connected to the catcher housing through the fixing frame 34. The rod 31 and the C-shaped steel frame 32 are respectively connected to the fixing frame 34 through connecting shafts 35. A spring is installed inside the connecting pin 33. Several through holes 36 are provided on the C-shaped steel frame 32. The through holes 36 are configured to cooperate with the connecting pin 33.

The steel cables 21 in the other three directions are connected to the suction anchor 23, which provides both horizontal and vertical tension to the entire device. The tension provided by the steel cables 21 cancels out the resultant force of buoyancy and gravity of the entire device, achieving overall balance and stability. For clarity of the structure, the steel cables 21 shown in the illustration are relatively short; their length should be adjusted according to actual needs.
