Description

Technical Field

[0001] The present invention relates to the technical field of wave energy collection devices, and in particular to a double-magnet magnetically driven wave energy collector, equipment and a wave energy collection method. Background Art

[0002] At present, the equipment used for ocean observation is mainly divided into fixed-point and mobile observation platforms, including ARGO buoys, ocean data buoys, unmanned ships, etc. These marine equipment integrate a large number of sensors to obtain key ocean information. The long-term, all-time and space monitoring of ocean observation equipment requires a lot of electricity. Simply increasing the number of built-in batteries or reducing the power consumption of the platform still cannot meet the long-term endurance requirements. In the ocean, waves are composed of many regular waves with different frequencies, wave directions, wavelengths and wave heights that are superimposed in a disordered manner. The wave height is usually between 0.5-2.3m, the average frequency is less than 1Hz, and it has the characteristics of low frequency and random waveform.

[0003] The main difficulty faced in the research on wave energy collection technology for powering offshore equipment is that ultra-low frequency and irregular wave-induced mechanical energy is difficult to efficiently convert into electrical energy output, the energy conversion efficiency is low, and the output power density is still not ideal.

[0004] Researchers have adopted wave energy collectors to solve the above-mentioned difficult problems. Among them, wave energy collectors are mainly composed of two parts: energy capture mechanism and transduction mechanism. The energy capture mechanism is mainly used to capture the wave-excited mechanical energy received by the device's carrying platform and convert it into different forms of mechanical energy inside the device. Common energy capture mechanisms include oscillating water column type, wave surface raft type, oscillating floating body type, nodding duck type, pendulum type, etc. The transduction mechanism mainly converts the mechanical kinetic energy of the internal structure movement into electrical energy through the principle of electromechanical coupling, covering three electromechanical coupling transduction principles: piezoelectric, electromagnetic and nano-triboelectric. The output performance of piezoelectric, triboelectric and electromagnetic electromechanical coupling transduction mechanisms is related to their coupling frequency.

[0005] Since the wave excitation frequency in the marine environment is low and the energy-harvesting structure of the wave energy collector is usually in a state of follow-up low-frequency motion, the output performance is generally low. In order to further improve the output performance of the wave energy collector, researchers proposed a frequency-upgrading mechanism transduction method to convert the low-frequency motion of the energy-harvesting structure into high-frequency motion of the transduction mechanism. At present, there are relatively few studies on the frequency-upgrading mechanism for wave energy collection. The existing frequency-upgrading mechanisms for wave energy collection are mainly divided into the following three types: 1. Gear-speed frequency-upgrading mechanism; 2. Non-contact magnetic drive frequency-upgrading mechanism; 3. Contact frequency-upgrading mechanism.

[0006] However, the existing wave energy harvesting upconversion mechanisms have their own shortcomings, as follows:

[0007] 1. The gear speed increase and frequency increase method refers to the wave energy collection device using the master and slave gears to cooperate in transmission to realize the conversion of low-frequency motion of the energy capture mechanism into high-frequency motion of the energy conversion mechanism. Usually the main gear is fixedly connected to the energy capture structure, and the secondary gear is partially fixedly connected to the energy conversion mechanism. The frequency increase effect directly depends on the transmission ratio between the gears. The higher the transmission ratio, the better the frequency increase effect, but it also requires a greater external driving force. In the marine environment, the wave motion is random, and the repeated reversal of the gear motion will also cause accelerated wear of the parts, and ultimately reduce the efficiency of wave energy collection.

[0008] 2. The non-contact magnetic drive frequency upscaling mechanism refers to the conversion of the low-frequency motion of one magnet to the high-frequency motion of the other magnet through the attraction and repulsion between the two magnets. The two magnets are respectively connected to the energy capture structure and the energy conversion structure in the wave energy collector, and the energy conversion structure usually adopts a cantilever beam, which takes advantage of the low inherent frequency of the cantilever beam itself. However, the current technology has not yet achieved a high multiple frequency upscaling effect, and the performance of the wave energy collector has not yet achieved a breakthrough.

[0009] 3. The contact frequency-upgrading mechanism transforms the non-contact magnetic force influence into the contact collision influence based on the magnetic drive frequency-upgrading mechanism, and changes the motion state of the object in the form of collision. Wave energy collectors based on the contact frequency-upgrading mechanism usually use cantilever beams as transducer structures, and cause high-frequency vibrations of the cantilever beam structure through low-frequency collisions from the outside world, thereby achieving high-power output of the device. However, the collision process also accelerates the damage of the device, which does not meet the requirements of long-term stable operation in the marine environment. Summary of the invention

[0010] In view of the deficiencies in the prior art, the present invention discloses a double-magnet magnetically driven wave energy collector, a device and a wave energy collection method.

[0011] The technical solution adopted by the present invention is as follows:

[0015] When the dual-magnet magnetically driven wave energy collector is acted upon by an external force, the movement of the energy-capturing component is reciprocating linear motion. During the reciprocating motion of the energy-capturing component, the energy-conversion magnet of the energy-conversion system is alternately affected by the energy-capturing magnets in the two energy-capturing components, and the energy-conversion magnet rotates. During the rotation, the magnetic flux lines cut through the copper coil, thereby realizing electromagnetic power generation.

[0020] Its further technical feature is that the number and thickness of the two energy conversion magnets are the same.

[0023] Its further technical feature is that the carrying device includes a shell, at least two platforms are arranged in the shell, the platforms are used to install the double-magnet magnetic-driven wave energy collector, and a top cover is arranged on the top of the shell.

[0024] A wave energy collection method utilizes the above-mentioned dual-magnet magnetic-driven wave energy collector, characterized in that: when the dual-magnet magnetic-driven wave energy collector is affected by waves in an ocean environment and shakes, the energy-capturing component slides along the length direction of the guide element due to the inertial force, and the waves excite the dual-magnet magnetic-driven wave energy collector back and forth. The movement of the energy-capturing component presents reciprocating linear motion. The energy-conversion magnet of the energy-conversion system is alternately affected by the energy-capturing magnets of the two energy-capturing components, and the energy-conversion magnet rotates. During the rotation, the magnetic flux lines cut the copper coil, and the energy-conversion system converts the wave energy into electrical energy.

[0025] The above technical solution of the present invention has the following advantages compared with the prior art:

[0026] 1. The present invention designs a double-magnet driven wave energy collection device, which can collect ultra-low frequency and arbitrary direction wave energy through a cross array installation method.

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0037] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only reference directions of the accompanying drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention. In addition, in all embodiments, the same reference numerals represent the same elements.

[0038] Embodiment 1:

[0039] Combination Figure 1-Figure 3 , a double-magnet magnetic drive wave energy collector, comprising

[0040] The energy capture system includes two energy capture components 1 and at least one guide element 3. The two energy capture components 1 are respectively arranged on both sides of the guide element 3. The energy capture components 1 include an energy capture magnet frame 11 and an energy capture magnet 12 fixed in the energy capture magnet frame 11. The energy capture magnets 12 of the two energy capture components 1 are opposite to each other with the same poles.

[0041] The transducer system 2 is arranged between the two energy-capturing components 1 and is movably connected to the guide element 3. The transducer system 2 includes a transducer fixing frame 21 and a transducer module 22 fixed to the transducer fixing frame 21. The transducer module 22 includes a copper coil 221, a rotating bracket 222, a transducer magnet frame 223 and two transducer magnets 224 with different polarities from the energy-capturing magnet 12. The copper coil 221 is sleeved on the rotating bracket 222, and the two transducer magnets 224 are fixed on both sides of the transducer magnet frame 223. The transducer magnet frame 223 and the rotating bracket 222 are rotatably connected.

[0042] When the dual-magnet magnetically driven wave energy collector is acted upon by an external force, the movement of the energy-capturing component 1 is reciprocating linear motion. During the reciprocating motion of the energy-capturing component 1, the energy-converting magnet 224 of the energy-converting system 2 is alternately affected by the energy-capturing magnets 12 in the two energy-capturing components 1, and the energy-converting magnet 224 rotates. During the rotation, the magnetic flux lines cut the copper coil 221, thereby realizing electromagnetic power generation.

[0043] The above provides a dual-magnet magnetically driven wave energy collector, which collects wave energy and converts it into low-frequency motion of the internal structure, and finally converts the low-frequency motion into high-frequency rotation of the transducer magnet through the transducer system to achieve efficient power generation.

[0044] In this embodiment, the energy-trapping magnet 12 includes a group of N-pole magnets and S-pole magnets that attract each other.

[0045] In this embodiment, the transducer fixing frame 21 includes a set of brackets, the brackets are provided with two through holes, and linear bearings 31 are installed in the through holes, and the linear bearings 31 pass through the guide element 3. The brackets are provided with a notch, and the notch is clamped with the transducer module 22.

[0046] Preferably, the shape of the through hole is the same as the cross-sectional shape of the guide element 3 , and the guide element 3 may be a rod or a plate.

[0047] In this embodiment, the copper coil 221 is disposed in the middle of the rotating bracket 222 , and the inner diameter of the copper coil 221 is the same as the outer diameter of the rotating bracket 222 .

[0048] In this embodiment, a central hole is provided on the side of the rotating bracket 222, and the central hole is used to install the rotating bearing 225 and the rotating shaft 226. The rotating bearing 225 is sleeved on the rotating shaft 226, and the rotating shaft 226 passes through the rotating bracket 222 and the transducer magnet frame 223 in sequence. The outer ring and the inner ring of the rotating bearing 225 are respectively interference fit with the shafts on the rotating bracket 222 and the transducer magnet frame 223.

[0049] In this embodiment, the transducer magnet frame 223 defines a magnet accommodating cavity, which is concave along the axial direction of the transducer magnet frame 223 . The diameter of the transducer magnet 224 is the same as the inner diameter of the magnet accommodating cavity, and the magnet accommodating cavity can effectively fix the transducer magnet 224 .

[0050] In this embodiment, in order to ensure the balance and stability of the transducer module 22 , the number and thickness of the two transducer magnets 224 are the same.

[0051] In this embodiment, the energy-capturing magnet frame 11 includes a set of frames, and the frames are provided with mounting grooves for mounting the energy-capturing magnets 12. The frames are also provided with connecting holes for passing the guide elements 3.

[0052] Preferably, the shape of the connecting hole is the same as the cross-sectional shape of the guide element 3 .

[0053] Embodiment 2:

[0054] Combination Figure 4 and Figure 5 A dual-magnet magnetically driven wave energy collection device comprises a carrying device 4, in which at least two dual-magnet magnetically driven wave energy collectors of embodiment 1 are arranged, and the dual-magnet magnetically driven wave energy collectors can be cross-fixed in the carrying device 4 at any angle.

[0055] The above provides a dual-magnet magnetically driven wave energy collection device, which is used to carry a dual-magnet magnetically driven wave energy collector. The dual-magnet magnetically driven wave energy collector can be installed in upper and lower layers at cross angles to realize the collection of wave energy in any direction. The converted electrical energy can be supplied to various sensors inside the ocean buoy, realizing long-term unmanned operation.

[0056] In this embodiment, the mounting device 4 includes a shell, and at least two platforms 42 are arranged inside the shell. The platforms 42 are used to install the double-magnet magnetic-driven wave energy collector, and a top cover 41 is arranged on the top of the shell.

[0057] Preferably, the carrying device 4 is an ocean buoy.

[0058] The working principle of this embodiment is as follows:

[0059] When the carrying device 4 is stationary, the energy-capturing components 1 are symmetrically arranged on both sides of the energy conversion system 2 .

[0060] When the carrying device 4 is affected by waves and shakes in the marine environment, the energy-capturing component 1 will slide along the length direction of the guide element 3 due to the inertial force. Because the waves will excite the buoy back and forth, the movement of the energy-capturing component 1 appears as reciprocating linear motion.

[0061] The energy-capturing magnet 12 in the energy-capturing component 1 will also reciprocate linearly. During the reciprocating motion, the energy-converting magnet 224 in the energy-converting system 2 is alternately affected by the energy-capturing magnets 12 in the two energy-capturing components 1, so the energy-converting magnet 224 rotates at a high speed. During the rotation, the magnetic flux lines cut the copper coil 221 to realize electromagnetic power generation, thereby converting wave energy into electrical energy and powering various sensors inside the carrying device 4.

[0062] Embodiment 3:

[0063] A wave energy collection method is provided, which utilizes the dual-magnet magnetic-driven wave energy collector of Example 1. When the dual-magnet magnetic-driven wave energy collector is affected by waves in an ocean environment and shakes, the energy-capturing component 1 slides along the length direction of the guide element 3 due to the inertial force. The waves excite the dual-magnet magnetic-driven wave energy collector back and forth. The movement of the energy-capturing component 1 is presented as reciprocating linear motion. The energy-capturing magnet 224 of the energy-capturing system 2 is alternately affected by the energy-capturing magnets 12 of the two energy-capturing components 1. The energy-capturing magnet 224 rotates. During the rotation, the magnetic flux lines cut the copper coil 221. The energy-capturing system 2 converts the wave energy into electrical energy.

[0064] Comparative Example 1:

[0065] A Chinese invention patent (CN113250893B) discloses a pendulum up-conversion wave energy collection device and a carrying device, in which the following are arranged in the shell: an energy capture system, including a mass pendulum and an energy capture magnet, the upper end of the mass pendulum is rotatably connected to the shell, and the energy capture magnet is connected to the mass pendulum; an electromagnetic energy conversion system, arranged on one side of the mass pendulum, the electromagnetic energy conversion system includes a fixed seat, a rotating bracket, a metal coil, and an energy conversion magnet, the metal coil is sleeved on the fixed seat, the rotating bracket is arranged in the fixed seat and rotatably connected to the fixed seat, and the energy conversion magnet is connected to the rotating bracket; the mass pendulum can drive the energy capture magnet to swing, and the energy capture magnet applies constantly changing attraction and repulsion to the energy conversion magnet to drive the energy conversion magnet to reciprocate, so that the metal coil cuts the magnetic flux lines of the energy conversion magnet when it reciprocates and generates alternating current.

[0066] Compared with Example 1: The structures of the middle power generation modules used in Example 1 and Comparative Example 1 are similar, but the driving methods are completely different. Example 1 protects the method of generating electricity by driving the power generation module with double magnets.

[0067] Among them, the straight line where the direction of the rotation axis of the energy conversion magnet 224 is located and the straight line where the moving track direction of the energy capture magnet 12 is located are perpendicular in space. Take the two energy capture magnets 12 as an example, when the middle energy conversion system 2 is on the left, the energy conversion magnet 224 is more affected by the energy capture magnet 12 on the left, and the N pole of the energy conversion magnet 224 is attracted; when the energy conversion system 2 moves to the middle, the two energy capture magnets 12 have the same influence on the energy conversion magnet 224, and the energy conversion magnet 224 does not flip; when the energy conversion system 2 continues to move to the right, the energy capture magnet 12 on the right has a greater influence on the energy conversion magnet 224, and the N pole of the energy conversion magnet 224 needs to face right, which is opposite to the situation when the energy conversion system 2 is on the left. At this time, the energy conversion magnet 224 flips, and because the speed of the energy conversion magnet 224 flips fast enough, it starts to rotate back and forth under the influence of the moment of inertia after obtaining kinetic energy, and the magnetic flux lines cut the copper coil 221 in the energy conversion system 2 to achieve electromagnetic power generation.

[0068] Comparative Example 1 uses only one magnet drive, which is different from Example 1. Secondly, the moving trajectory of the energy-capturing magnet that mainly provides power and the rotation axis direction of the energy-converting magnet are parallel or intersecting in space, which is also different from Example 1.

[0069] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
