Description

Technical Field

[0001] This invention relates to the field of marine energy power generation technology, and in particular to a float-type power generation device that effectively utilizes wave energy and tidal energy and improves power generation efficiency. Background Technology

[0002] With the continuous development of human society and the world economy, traditional energy sources are becoming increasingly scarce, and the ecological environment is suffering from serious pollution and damage. The large-scale use of fossil fuels has caused serious ecological and environmental problems. Under these circumstances, humanity has gradually turned its attention to the vast field of ocean energy. Wave energy, with its advantages of wide distribution, high energy flux density, less time constraint, and low development difficulty, is known as the highest grade of ocean energy. Tidal energy, generally the kinetic energy of tidal currents, is more regular in its changes and has a higher density and greater stability than wave energy. Today, research on various ocean energy conversion devices is increasingly becoming a hot topic worldwide.

[0003] In recent years, ocean energy power generation devices have evolved and come in many varieties. Existing technologies include devices that generate electricity using tidal energy and devices that generate electricity using wave energy, but there are few devices that effectively combine the two and comprehensively utilize ocean energy capture methods. This invention provides a pendulum-type power generation device that combines wave energy and tidal energy, solving the technical problems of single ocean energy utilization and low power generation efficiency in existing devices.

[0004] This invention integrates wave energy and tidal energy to design a float-type power generation device. The turbofan maintains a constant rotation in one direction during the float's heaving motion, and a transmission mechanism continuously generates electricity. Simultaneously, the float and the column are connected by hydraulic cylinders, and the hydraulic transmission system is built into the float, converting hydraulic energy into electrical energy for the generator. Both the turbofan and float hydraulic systems employ independent transmission mechanisms, enabling effective and comprehensive utilization of wave and tidal energy, thus improving the utilization rate of ocean energy. The device's transmission system has a simple structure and high energy transfer efficiency. Summary of the Invention

[0005] This invention provides a float-type power generation device that combines wave and current utilization, addressing the technical problems of single marine energy utilization and low power generation efficiency in existing power generation devices. It includes: a float power generation component, a turbofan power generation component, and a support column. Furthermore, a hydraulic transmission system is built into the float; the turbofan power generation component is rigidly connected to the support column.

[0006] The float power generation assembly includes: a float shell, inside which are arranged a rigid disc, a hydraulic cylinder, a battery, a transmission line, etc.; one end of the hydraulic cylinder is fixedly connected to the rigid disc, and the other end is fixed inside the float shell; the battery and the transmission line are arranged inside the float shell; one end of the column is connected to the rigid disc, and the other end is rigidly connected to the turbofan power generation assembly.

[0007] Furthermore, the float-generating component oscillates with the waves, creating relative motion with the column. This causes the rigid disc to drive the hydraulic cylinder at the same end to reciprocate up and down, pushing the oil medium in the hydraulic cylinder into the hydraulic system to form a circuit. The oil medium is then output from the hydraulic cylinder through oil pipes, enters the accumulator for stabilization, and then enters the hydraulic motor. The rotation of the hydraulic motor drives the first generator to generate electricity.

[0008] Furthermore, the turbofan power generation assembly includes: a turbofan, a main rotating shaft, a generator, a main shaft flange, an end cover, a bearing housing, a coupling, a speed increaser, and a brake disc; the turbofan consists of five symmetrical airfoil blades and a hub, rotating around the rotating shaft; due to its unique structural design, the blades maintain rotation in one direction during heave regardless of wave or current direction; the main rotating shaft is fitted inside the bearing housing and connected to the second generator via a coupling; the end cover provides protection; the speed increaser increases the generator speed; and the brake disc provides buffering and stabilization.

[0009] Furthermore, the pressure gauge can detect the system pressure, enabling the hydraulic motor to operate continuously or intermittently; the flow meter and pressure sensor can measure the flow and pressure at the downstream end of the system; the relief valve mainly serves as a constant pressure relief valve in the hydraulic equipment, used for unloading the pressure stabilizing system and for safety protection.

[0010] The beneficial effects of this invention are:

[0011] This invention integrates wave energy and tidal energy to design a float-type power generation device. During operation, the float is subjected to wave force, causing it to oscillate relative to a column. A hydraulic cylinder, driven by a rigid disc, converts the mechanical energy absorbed by this relative motion into hydraulic energy. This hydraulic energy is then converted into kinetic energy by a rotating hydraulic motor, which in turn drives a generator to generate electricity. The turbofan is subjected to ocean current force during its oscillating motion. Due to its unique structural design, the blades maintain a single rotation direction regardless of wave or current direction while following the column's oscillation, continuously generating electricity through a transmission mechanism. The turbofan and hydraulic system each employ an independent transmission mechanism, enabling effective and comprehensive utilization of wave and tidal energy, thus improving the utilization rate of ocean energy. The device's transmission system has a simple structure and high energy transfer efficiency. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further illustrated below with reference to specific embodiments. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Modifications to the present invention in various equivalent forms all fall within the scope defined by the appended claims.

[0022] This invention provides, for example Figure 1-5As shown, a specific embodiment of the present invention provides a float-type power generation device that utilizes both wave and current, including: a float power generation component 1, a turbofan power generation component 3, and a column 2. A rigid disc 12 is built into the float housing 11. The turbofan power generation component 3 is rigidly connected to the column 2. The float housing 11 also contains a hydraulic cylinder 13, a battery 14, and a transmission line 15. One end of the hydraulic cylinder 13 is fixedly connected to the rigid disc 12, and the other end is fixed inside the float housing 11. The battery 14 and the transmission line 15 are disposed inside the float housing 13. One end of the column 2 is connected to the rigid disc 12, and the other end is rigidly connected to the turbofan power generation component 3. The turbofan power generation component 3 includes: a turbofan 301, a main rotating shaft 35, a second generator 310, a main shaft flange 33, an end cover 34, a bearing seat 36, a coupling 37, a speed increaser 38, and a brake disc 39. The turbofan 301 consists of five symmetrical airfoil blades 31 and a hub 32, rotating around the main drive shaft 35. Due to its unique structural design, the blades 31 maintain rotation in one direction during heave regardless of wave or current direction. The main drive shaft 35 is housed in a bearing housing 36 and connected to the second generator 310 via a coupling 37. The end cover 34 provides protection; the speed increaser 38 increases the speed of the second generator; and the brake disc 39 provides buffering and stabilization. The hydraulic transmission system in the float generator assembly 1 includes: check valves 41 and 43, a hydraulic cylinder 42, an accumulator shut-off valve 44, an accumulator 45, a pressure gauge shut-off valve 46, a pressure gauge 47, a relief valve 48, a hydraulic motor 49, a throttle valve 410, and a first generator 411. When the upper chamber of the hydraulic cylinder 42 draws in oil, the lower chamber becomes the working chamber, pressurizing the oil. The high-pressure oil in the lower chamber enters the hydraulic motor 49 through the right side of the check valve 43, thereby driving the first generator 411 to generate electricity. Conversely, the same applies. Inside the generator hydraulic system, the accumulator 45 effectively reduces energy waste, helps with system vibration reduction, stabilizes system pressure, keeps the generator voltage stable, and improves the quality of power generation.

[0023] The working process of this invention is as follows:

[0024] When this invention is placed in the sea, the float-generating component will float on the surface, rising and falling with the waves. Because the column is rigidly connected to the turbofan generator, and the other end is connected to the hydraulic cylinder inside the float via a rigid disc, the float-generating component and the column will experience relative motion in the waves. During the process of creating elevation differences, the float-generating component reciprocates through the hydraulic cylinder. This drives the piston rod in the hydraulic cylinder to reciprocate in one direction, pushing the oil medium into the hydraulic system to form a circuit. A one-way valve ensures that the medium discharged from the hydraulic cylinder is always in a one-way circuit. The oil medium enters and exits from the hydraulic cylinder through the inlet, enters the accumulator for pressure stabilization, and then enters the hydraulic motor. The rotation of the hydraulic motor drives the first generator to generate electricity. A pressure gauge can detect the system pressure, and the pressure gauge shut-off valve controls the continuous or intermittent operation of the hydraulic motor. The relief valve mainly serves as a constant pressure relief valve in the hydraulic transmission, used for unloading the pressure stabilization system and for safety protection. Due to the design of the turbofan blades, the turbofan rotates only in one direction under the influence of ocean currents. This rotation is transmitted to the second generator via the main shaft, coupling, speed increaser, and brake disc, causing the second generator to rotate and generate electricity. The end cover provides protection; the speed increaser increases the speed of the second generator; and the brake disc provides cushioning and stabilization.

[0025] This invention is ingeniously designed and structurally sound, making full use of wave energy and tidal energy. During operation, the float is subjected to wave force, causing it to oscillate relative to the column. A hydraulic cylinder, driven by a rigid disc, converts the mechanical energy absorbed by this relative motion into hydraulic energy. This hydraulic energy is then converted into kinetic energy by a rotating hydraulic motor, which in turn drives a generator to generate electricity. The turbofan is subjected to ocean current force during its oscillating motion. Due to its unique design, the blades maintain a single rotation direction regardless of wave or current direction while oscillating with the column, continuously generating electricity through a transmission mechanism. The turbofan and hydraulic system each employ an independent transmission mechanism, enabling effective and comprehensive utilization of wave and tidal energy, thus improving the utilization rate of ocean energy. The device's transmission system has a simple structure and high energy transfer efficiency.

[0026] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
