Description

Technical Field

[0001] This invention relates to the field of power generation technology, and in particular to an integrated power generation device combining wave energy and ocean current energy. Background Technology

[0002] With the development of urban industries, the demand for electricity is constantly increasing. Promoting the green and low-carbon transformation of energy can achieve green energy development and utilization, thereby alleviating the pressure of climate change and promoting the development of efficient, intelligent, and green emerging industries. Ocean wave energy reserves are enormous, and ocean waves possess various forms of energy, such as wave energy and ocean current energy. Moreover, ocean wave energy power generation is less polluting, making it a renewable energy source with great potential. However, most existing power generation devices that utilize these energy sources only utilize one type, failing to achieve comprehensive and full utilization. Some integrated power generation devices only consider the separate generation of wave energy and ocean current energy, with the two types of power generation devices merely spatially aggregated without interconnection, serving only as a simple power addition. This results in problems such as low engine speed and difficulty in effectively improving efficiency. Waves are the up-and-down movement of seawater, which inevitably leads to the bidirectional movement of wave energy absorption devices, which is not conducive to the utilization of wave energy. The operation of existing power generation devices requires multiple gear drives, reducing efficiency and increasing the overall cost of the device.

[0003] Therefore, how to provide an integrated wave energy and ocean current energy power generation device that can couple wave energy power generation devices and ocean current energy power generation devices together to achieve the effect of adding generator speeds and thus improving energy utilization is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention proposes an integrated wave energy and ocean current energy power generation device, which aims to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention provides an integrated wave energy and ocean current energy power generation device, comprising:

[0007] A power generation mechanism, comprising a rotating part one and a rotating part two, wherein the rotating part one and the rotating part two rotate relative to each other and are capable of generating electricity;

[0009] A mechanical motion rectification mechanism includes a reciprocating lifting part, a rotary output part, and a motion rectification structure. The motion rectification structure connects the reciprocating lifting part and the rotary output part, and can convert the bidirectional lifting power of the reciprocating lifting part into the rotational power of the rotary output part. The rotary output part is driven by the rotary part II, and can drive the rotary part II to rotate in the opposite direction to the rotation direction of the rotary part I.

[0010] A wave energy capture mechanism, wherein the floating output end of the wave energy capture mechanism is driven to the reciprocating lifting unit to drive its lifting and lowering.

[0011] When the wave energy and ocean current energy integrated power generation device of the present invention is working, the ocean current energy capture mechanism is able to rotate under the action of ocean currents, thereby driving the rotating part one of the power generation mechanism to rotate and generate electricity, thus capturing ocean current energy. The wave energy capture mechanism normally floats on the sea surface and moves vertically up and down with the waves. The bidirectional power is input to the motion rectification structure through the reciprocating lifting part. The motion rectification structure converts the bidirectional lifting power into the unidirectional rotational power of the rotating output part, which in turn drives the rotating part two of the power generation mechanism to rotate and generate electricity, thus capturing wave energy. Since the rotating part two rotates in the opposite direction to the rotating part one, the input coupling of wave energy and ocean current energy is finally realized, achieving the summation effect of power generation, thereby improving energy utilization efficiency.

[0017] The beneficial effects of the above technical solution are: setting up a force sensor can record the energy input by the waves in real time, and then compare it with the output electrical energy to monitor the power generation efficiency of the system.

[0019] The beneficial effects of the above technical solution are as follows: Under the action of waves, the lifting power of the float is transmitted to the lifting rod through multiple evenly distributed transmission rods, which realizes a lightweight design, reduces its own inertial loss, and reduces the impact of wind flow; the inclined support of the transmission rods for the lifting rod can ensure that the lifting rod has a large lifting stroke, will not cause motion interference, and can also achieve flexible force transmission, playing a buffering role.

[0020] As a further improvement to the above technical solution, the motion rectification structure includes gear one, gear two, gear three, gear four, gear five, input shaft, one-way clutch one, one-way clutch two, one-way clutch three, connecting shaft and transmission screw.

[0021] One end of the input shaft is connected to one end of the transmission screw; the reciprocating lifting part is a nut and is screwed onto the transmission screw to drive the transmission screw to rotate in a lifting manner.

[0022] The other end of the input shaft coaxially passes through the center hole of gear one and is coaxially connected to gear three via one-way clutch three; the input shaft and gear one are coaxially connected via one-way clutch three; gear one is meshed with gear two; one end of the connecting shaft is coaxially fixedly connected to gear five, and the other end of the connecting shaft is coaxially connected to gear two via one-way clutch two; gear four is located between gear three and gear five and is meshed with both gear three and gear five;

[0023] When the input shaft rotates in the forward direction, it can transmit torque through the one-way clutch three to drive the gear three to rotate in the forward direction; when the input shaft rotates in the reverse direction, it can transmit torque through one-way clutch one, gear one, gear two, one-way clutch two, the connecting shaft, gear five, and gear four in sequence to drive the gear three to rotate in the forward direction; the gear three is coaxially fixedly connected to the rotary output part, and can drive the rotary part two to rotate in the forward direction through the rotary output part; the rotary output shaft of the ocean current energy capture mechanism can drive the rotary part one to rotate in the reverse direction.

[0026] The fixed end of the wave energy capture mechanism is fixed to the upper end of the housing; the transmission screw is rotatably installed inside the housing; the floating output end of the wave energy capture mechanism extends downward into the interior of the housing.

[0027] The beneficial effects of the above technical solution are: the casing serves as the mounting base and also acts as a protective shell to protect the internal components.

[0028] As a further improvement to the above technical solution, the first rotating part is a motor stator, and the second rotating part is a motor rotor; both the first rotating part and the second rotating part are located inside the housing; the first rotating part is rotatably mounted on the inner peripheral wall of the housing; the ocean current energy capture mechanism is mounted on the outer peripheral wall of the housing, and its rotating output shaft passes through the outer peripheral wall of the housing and is coaxially fixed with the motor stator; the rotating output part is an output shaft assembly; the motor rotor is coaxially fixed with the gear three through the output shaft assembly.

[0029] The beneficial effect of the above technical solution is that the power generation mechanism is built into the casing, which protects the power generation mechanism.

[0031] The beneficial effect of the above technical solution is that the bevel gear transmission mechanism can convert the rotational motion of the vertically arranged transmission screw into the rotation of the horizontal shaft, thereby driving the input shaft to rotate, so as to horizontally connect with the rotating output shaft of the ocean current energy capture mechanism.

[0032] As a further improvement to the above technical solution, a base plate is also included, on which the housing is mounted.

[0033] The beneficial effect of the above technical solution is that the base plate plays a role in stabilizing the entire device and ensuring that the device remains in a stable position in the ocean.

[0050] The power generation mechanism 1 includes a rotating part 11 and a rotating part 2 12. The rotating part 11 and the rotating part 2 12 can generate electricity when they rotate relative to each other.

[0051] The power output end of the ocean current energy capture mechanism 2 is connected to the rotating part 11 to drive its rotation.

[0052] The mechanical motion rectification mechanism includes a reciprocating lifting part, a rotary output part, and a motion rectification structure 3. The motion rectification structure 3 connects the reciprocating lifting part and the rotary output part, and can convert the bidirectional lifting power of the reciprocating lifting part into the rotational power of the rotary output part. The rotary output part is connected to the rotary part 2 12, and can drive the rotary part 2 12 to rotate in the opposite direction to the rotation direction of the rotary part 1 11.

[0053] The floating output end of the wave energy capture mechanism 4 is connected to the reciprocating lifting unit to drive its lifting and lowering.

[0054] In this embodiment, when the integrated wave energy and ocean current energy power generation device is working, the ocean current energy capture mechanism 2 rotates under the action of ocean currents, thereby driving the rotating part 11 of the power generation mechanism 1 to rotate and generate electricity, thus capturing ocean current energy. The wave energy capture mechanism 4 normally floats on the sea surface and moves vertically up and down with the waves. The bidirectional power is input to the motion rectification structure 3 through the reciprocating part. The motion rectification structure 3 converts the bidirectional power of the up and down movement into the unidirectional rotational power of the rotating output part, which in turn drives the rotating part 12 of the power generation mechanism 1 to rotate and generate electricity, thus capturing wave energy. Since the rotating part 12 rotates in the opposite direction to the rotating part 11, the input coupling of wave energy and ocean current energy is finally realized, achieving the summation effect of power generation, thereby improving energy utilization.

[0055] In some embodiments, the ocean current energy capture mechanism 2 is a turbine; the rotating output shaft of the turbine is coaxially connected to the rotating shaft of the rotating part 11.

[0056] By capturing ocean current energy through turbines, it can be directly connected to the rotating part of the power generation mechanism to drive power generation, reducing unnecessary parts, thereby reducing costs and improving efficiency.

[0057] In some embodiments, the wave energy capture mechanism 4 includes a float 41, a lifting rod 42, and a guide cylinder 43; the float 41 is slidably sleeved on the outer periphery of the guide cylinder 43, and the lifting rod 42 is coaxially and movably inserted through the cavity of the guide cylinder 43; the float 41 is connected to the lifting rod 42 in a driving manner, and can capture wave energy to drive the lifting rod 42 to rise and fall by floating; one end of the lifting rod 42 is connected to a reciprocating lifting part in a driving manner to drive it to rise and fall.

[0058] The float 41 can stably capture wave energy under the sliding guidance of the guide cylinder 43. The cylinder cavity of the guide cylinder 43 guides the lifting rod 42 to rise and fall, which further improves the transmission accuracy, increases the service life, and reduces mechanical wear.

[0059] Specifically, the float 41 has a central through hole in the middle of its top surface; the float 41 is movably sleeved on the guide cylinder 43; the outer peripheral wall of the guide cylinder 43 is provided with a guide slide rail 431 along the parallel axis; a slider 411 is fixedly installed at the top of the float 41 corresponding to the guide slide rail 431, and the slider 411 is slidably connected to the guide slide rail 431; the slider 411 and the guide slide rail 431 cooperate to realize the stable lifting and lowering of the float 41 without rotating around the axis of the guide cylinder 43.

[0063] Under the action of waves, the lifting power of the float 41 is transmitted to the lifting rod 42 through multiple evenly distributed transmission rods 451, which realizes a lightweight design, reduces its own inertial loss, and reduces the impact of airflow. The inclined support of the transmission rods 451 for the lifting rod 42 can ensure that the lifting rod 42 has a large lifting stroke, without motion interference, and can also achieve flexible force transmission, playing a buffering role.

The housing 313 is completely sealed to prevent water ingress. The upper end of the guide cylinder 43 extends upward above the water surface; a seal can be made between the upper port of the guide cylinder 43 and the outer peripheral wall of the lifting rod 42.
