DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Examples, such as Figure 1-Figure 11As shown: The present invention provides a swing-coupled wave power generation lifesaving buoy, which includes a main floating body 1 in structure, and includes a lifesaving system, a rescue system and a power generation system in function. A control part 1a, a material part 1b and a light part 1c are arranged in the main floating body 1. The control part 1a has a corresponding circuit structure, including a GPS module, an energy storage module and a rectifier module. In terms of function, it can also have environmental perception and intelligent early warning capabilities according to needs. The material part 1b is used to store rescue materials. The light part 1c is connected to the control part 1a. A rescue belt 4 is arranged at the bottom of the main floating body 1. A plurality of power generation floating bodies 2 are connected to the outside of the main floating body 1 through a connector 3. Thus, a lifesaving system is formed by the rescue belt 4 and the material part 1b. The rescue belt 4 is used to allow the drowning person to cling to and be fixed on the main floating body 1, and the rescue materials are stored through the material part 1b. Rescue materials such as food and medicine are used to supply the drowning people; a rescue system is formed by the light part 1c and the GPS module. The GPS module transmits positioning information to the outside world, and the light part 1c flashes according to the SOS Morse signal to ask for help from the surrounding; and a power generation system is formed by the power generation float 2, the energy storage module and the rectifier module. The power generation float 2 is stimulated by the waves to generate electricity, and is electrically connected to the power generation float 2. The current generated by the power generation is rectified by the rectifier module and the energy storage module is used to store and distribute the electricity, so as to power the entire lifesaving buoy. Not only that, technical personnel in this field can also set solar panels on the outside of the main float 1 to connect with the rectifier module and the energy storage module, cooperate with power generation when the sun is sufficient, and use the power generation float 2 as the main power supply operation under bad weather conditions.

[0035] The power generation float 2 includes an outer shell 21 and a lower buoy 22, and the outer shell 21 and the lower buoy 22 form a float structure. The power generation structure in the power generation float 2 includes a swing power generation unit and an oscillation power generation unit, wherein the swing power generation unit includes a dielectric plate 26 and an electrode seat 28, and a swing rod 25 is provided at the top of the dielectric plate 26, and the top of the swing rod 25 is swingably connected to the top of the outer shell 21. In this embodiment, the swing rod 25 is swingably connected to the outer shell 21 through a ball bearing 24, and the electrode seat 28 is elastically connected to the lower buoy 22 through an elastic seat 27, and the oscillation power generation unit includes an oscillation component 29, which is movably nested on the swing rod 25, and the oscillation component 29 includes at least one group of contact plates that contact and move away from each other in response to external vibrations;

[0036] It should also be noted that the contact surface between the dielectric plate 26 and the electrode holder 28 and the contact surface between the contact plates have different electronegativity, so that the two carry different charges when they are in contact, and the contact surface with positive electronegativity generates current by transferring charge through potential difference, and the contact surface with positive electronegativity is electrically connected to the control part 1a through an external circuit, so that the current flows to the control part 1a, the rectifier module is used to receive and rectify the current generated by the charge transfer in the power generation float 2, and the energy storage module is used to store the electric energy generated by the power generation float 2 and distribute it to the control part 1a.

[0037] It should be noted that positive electronegativity and negative electronegativity are used to indicate the electronegativity characteristics of being relatively easy to lose electrons and relatively easy to gain electrons. In the present embodiment, the contact surface material with positive electronegativity is made of copper, and the contact surface material with negative electronegativity is made of polytetrafluoroethylene. Copper is easier to lose electrons than polytetrafluoroethylene and thus carries a positive charge, thus exhibiting positive electronegativity. Polytetrafluoroethylene is negatively charged because it is easy to gain electrons, thus exhibiting negative electronegativity.

[0038] To this end, for the swing power generation part, the electrode seat 28 is in the shape of a concave spherical surface and the center of the spherical surface is located at the swing connection point at the top of the swing rod 25. The bottom surface of the dielectric plate 26 is in the shape of a spherical surface that fits the electrode seat 28. The dielectric plate 26 swings with the swing connection point at the top of the swing rod 25 as a fulcrum in response to external vibration and moves in contact on the electrode seat 28. The electrode seat 28 has positive electronegativity and has at least two contact surfaces connected by an external circuit, so that when there is a potential difference between the two contact surfaces, the charge can be transferred between the contact surfaces through the external circuit. Specifically, the electrode seat 28 includes a middle plate 281 and a side ring 282 surrounding the outer circle of the middle plate 281. An external circuit is connected between the middle plate 281 and the side ring 282. Therefore, the two contact surfaces connected by the external circuit are composed of the middle plate 281 and the side ring 282, and the dielectric plate 26 has negative electronegativity. The dielectric plate 26 and the electrode seat 28 are charged with different charges through contact or friction.

[0039] Since the elastic seat 27 below the electrode seat 28 has an upward elastic force, the electrode seat 28 is driven upward to contact the dielectric plate 26, so that the dielectric plate 26 and the electrode seat 28 are frictionally contacted and coupled. It should be noted that the arc length of the side ring 282 on the vertical cross section is equal to or greater than the arc length of the middle plate 281 on the vertical cross section, and the arc length of the dielectric plate 26 on the vertical cross section is equal to or less than the arc length of the middle plate 281 on the vertical cross section. When the dielectric plate 26 and the middle plate 281 are in contact, the polytetrafluoroethylene material is in contact with the copper material. Due to the principle of electrostatic induction, the polytetrafluoroethylene material The dielectric plate 26 and the copper middle plate 281 carry equal amounts of negative and positive charges, respectively. Then, when stimulated by external waves, the swing rod 25 swings in the floating structure, and the polytetrafluoroethylene dielectric plate 26 moves from the copper middle plate 281 to the copper side ring 282. The amount of positive charge generated on the copper side ring 282 gradually increases, and the amount of positive charge on the copper middle plate 281 gradually decreases, thereby forming an electric potential difference between the two, driving electrons to transfer from the middle plate 281 to the side ring 282, forming a current in the external circuit, and being received and utilized by the rectifier module and the energy storage module.

[0040] It should be noted that since the equipment is continuously affected by wave fluctuations on the sea surface and the wave fluctuations are relatively frequent, the swing rod 25 is more likely to swing, which makes the charge state between the dielectric plate 26 and the electrode seat 28 be regarded as starting from the charge transfer caused by contact, or as starting from the charge transfer caused by friction.

[0041] For the oscillation power generation part, a group of contact plates has at least two contact plates with positive and negative charges coupled to each other, and the two contact plates are in contact and away from each other and connected through an external circuit, so that when there is a potential difference between the two contact surfaces, the charge can be transferred between the contact surfaces through the external circuit. For this purpose, the oscillation component 29 includes a plurality of retractable members 291 on the swing rod 25 and an oscillating block 292 installed on the top of the retractable member 291. In this embodiment, there are three retractable members 291, which are composed of a group of contact plates and are divided into two upper and lower contact plates. The upper and lower contact plates are curved and elastic and are arranged opposite to each other, thereby forming a spindle shape, a shuttle shape or an ellipse shape.

[0042] Specifically, the contact plate of the upper retractable member 291 includes a positive charge plate 291a made of copper, and the contact plate of the lower retractable member 291 is a sandwich structure and includes a negative charge plate 291b made of polytetrafluoroethylene, a positive charge plate 291a made of copper, and a negative charge plate 291b made of polytetrafluoroethylene in sequence. An external circuit is connected between the upper copper positive charge plate 291a and the lower copper positive charge plate 291a, so that the positive charge plates 291a and the negative charge plates 291b in the plurality of retractable members 291 on the swing rod 25 are arranged in sequence.

[0043] The positive charge plate 291a has positive electronegativity and the negative charge plate 291b has negative electronegativity. The contact plate at the upper end and the contact plate at the lower end of the retracting member 291 are charged with different charges through contact or friction. When the floating structure as a whole is not affected by the ups and downs of the waves, the pressure applied by the vibration block 292 to the retracting member 291 is greater than the elastic force of the contact plates arranged opposite to each other, so that the plurality of retracting members 291 are in a state of being squeezed and fitted to each other when stationary. The positive charge plate 291a at the upper end is fitted with the negative charge plate 291b at the lower end. The positive charge plate 291a made of copper and the negative charge plate 291b made of polytetrafluoroethylene carry equal amounts of positive charges. and negative charge, while the positive charge plate 291a made of copper at the lower end, which is sandwiched between two negative charge plates 291b made of polytetrafluoroethylene, is also positively charged. When the floating structure is affected by the ups and downs of waves, the vibrating block 292 responds to external vibrations and moves on the swing rod 25, thereby driving the contact plates of the retracting member 291 to move away from each other, causing an electric potential difference to be formed between the positive charge plate 291a at the upper end and the positive charge plate 291a at the lower end. Under the action of the potential difference, electrons flow from the positive charge plate 291a at the upper end with less positive charge to the positive charge plate 291a at the lower end with more positive charge, thereby forming a current in the external circuit, which is received and utilized by the rectifier module and the energy storage module.

[0044] It should be noted that the contact and separation vibration displacement amplitude of the oscillation component 29 is related to the natural frequency of the heave structure, and the natural frequency calculation formula is: ;

[0045] Among them, is the natural frequency of the oscillation component 29, m is the mass of the vibration block 292, k is the elastic coefficient of the oscillation component 29, k can be obtained by the linear fitting method of the static deformation under the action of multiple weights of different known masses. By controlling and adjusting the mass m of the vibration block 292, the natural frequency of the oscillation component 29 can be adjusted to make it close to the wave excitation frequency, thereby obtaining a larger actuation amplitude.

[0046] Therefore, when the power generation system is implemented, the wave fluctuations drive the floating structure to fluctuate up and down and sway left and right. During the swaying, the swing rod 25 swings in the floating structure, and the dielectric plate 26 made of polytetrafluoroethylene moves from the copper middle plate 281 to the copper side ring 282. The amount of positive charge generated on the copper side ring 282 gradually increases, and the amount of positive charge on the copper middle plate 281 gradually decreases, thereby forming an electric potential difference between the two, driving electrons to transfer from the middle plate 281 to the side ring 282, forming a current in the external circuit, and during the up and down fluctuations, The retractable parts 291 that are closely attached to each other are unfolded upward, and the positive charge plate 291a at the upper end is reduced after being unfolded. The positive charge plate 291a at the lower end is located between the two charge plates so that the amount of positive charge is greater than the positive charge plate 291a at the upper end, resulting in a potential difference between the positive charge plate 291a at the upper end and the positive charge plate 291a at the lower end. Electrons flow from the positive charge plate 291a at the upper end with less positive charge to the positive charge plate 291a at the lower end with more positive charge, thereby forming a current in the external circuit, which is received and utilized by the rectifier module and the energy storage module to provide energy for the lifesaving buoy.

[0047] In this embodiment, moreover, the swing rod 25 is swingably connected to the housing 21 through the ball bearing 24, and the ball bearing 24 is mounted on the housing 21 through the mounting frame 23. The mounting frame 23 can be fixed to the housing 21 by welding, bonding, bolts, rivets, etc., and a separation mechanism 5 is provided between the mounting frame 23 and the ball bearing 24 to separate the dielectric plate 26 and the electrode seat 28 and stop the oscillation assembly 29 from working when the floating structure of the power generation floating body 2 is filled with water and sinks;

[0048] To this end, a movable sleeve 241 is provided on the outer side of the ball head bearing 24, and a side mounting strip 243 is provided on the movable sleeve 241. A positioning groove 232 is provided on the inner side of the mounting frame 23, and the side mounting strip 243 is installed in the positioning groove 232. A limiting groove 233 is also provided on the inner side of the mounting frame 23. The disengagement mechanism 5 includes a limiting frame 51, and a recessed positioning hole 244 is provided on the side mounting strip 243. The limiting frame 51 is installed in the limiting groove 233 and engages with the positioning hole 244 of the side mounting strip 243. The limiting frame 51 limits the freedom of the side mounting strip 243 to disengage from the outer side of the positioning groove 232 in the limiting groove 233; the disengagement mechanism 5 also includes a floating bag 52 installed on the limiting frame 51, and the floating bag 52 is located at the top of the limiting frame 51 and at the outer side of the shell 21. The floating bag 52 is driven by the buoyancy of water to move the limiting frame 51 to the outer side of the limiting groove 233, so that the side mounting strip 243 in the positioning groove 232 is separated from the restriction of the limiting frame 51.

[0049] It should be noted that the first connection seat 231 and the second connection seat 242 are respectively provided on the movable sleeve 241 and the mounting frame 23. When the movable sleeve 241 is installed in place, the first connection seat 231 and the second connection seat 242 are connected, and the second connection seat 242 is connected to the external circuit of the swing power generation part and the oscillation power generation part. The external circuit is electrically connected to the control part 1a through the first connection seat 231 and the second connection seat 242.

[0050] Specifically, the side mounting strip 243 is spirally arranged on the side of the movable sleeve 241, the positioning groove 232 cooperates with the side mounting strip 243 to form a spiral inclination, and the angle between the projection of the side mounting strip 243 on the vertical plane and the horizontal plane is set within the range of 30°-60°. The positioning groove 232 limits the freedom of the movable sleeve 241 to move axially and rotate around the axis of the movable sleeve 241 through the side mounting strip 243. Only when the movable sleeve 241 is spirally moved from the mounting frame 23 can it be installed and removed, and the limiting groove 233 is vertical and parallel to the axis of the movable sleeve 241, limiting A recessed clearance groove 51a is provided at the bottom of the positioning frame 51, and the depth of the clearance groove 51a is set to be greater than the depth of the positioning port 244. When the floating structure is filled with water and sinks into the sea, the floating bag 52 is subjected to the upward buoyancy force so that the posture of the floating structure is adjusted to a state where the floating bag 52 is located at the top. The floating bag 52 drives the limiting frame 51 to move upward relative to the floating structure, so that the limiting frame 51 is separated from the positioning port 244, and the clearance groove 51a of the limiting frame 51 is moved to the positioning port 244. At this time, the positioning port 244 is in a released state, and the side strip 243 has a tendency to separate from the positioning groove 232.

[0051] In addition, a driving member 53 is provided at the bottom end of the limiting frame 51. The driving member 53 interferes with the movable sleeve 241 on the movement path in the limiting groove 233. In this embodiment, the driving member 53 adopts an annular structure, so that when the floating bag 52 continues to rise, the driving member 53 is used to support the bottom of the movable sleeve 241 to drive the movable sleeve 241, the ball head bearing 24, the swing rod 25 and the connected dielectric plate 26 to move upward, so that the movable sleeve 241 is separated from the mounting frame 23, the dielectric plate 26 and the electrode seat 28 are separated, and the first connecting seat 231 and the second connecting seat 242 are separated to disconnect the external circuit;

[0052] It should be noted at this point that the opening at the top of the shell 21 can be set according to actual needs. In the present embodiment, the opening is smaller than the retractable member 291, thereby allowing the float 52 to drive the retractable member 291 to rise and the shell 21 to bring the retractable member 291 down, so that the retractable member 291 is continuously in a compressed state, thereby not generating an electric potential difference, thereby avoiding charge transfer to generate current and electrostatic reaction to affect the surrounding biological environment.

[0053] In addition, the width of the positioning groove 232 is greater than the width of the side strip 243, the side top surface of the side strip 243 and the side bottom surface of the positioning groove 232 are magnetic and have the same magnetism, the side top surface refers to the area of ​​the two contact areas between the side strip 243 and the positioning groove 232 that is inclined to the top surface, and the side bottom surface refers to the area of ​​the two contact areas between the side strip 243 and the positioning groove 232 that is inclined to the bottom surface, and the bottom end of the positioning groove 232 has an elastic structure, and the side strip 243 The bottom end and the positioning opening 244 of the side mounting strip 243 are in interference fit between the bottom end of the positioning groove 232 and the limiting frame 51, and at this time there is a gap between the side bottom surface of the side mounting strip 243 and the side top surface of the positioning groove 232, that is, at this time, the side mounting strip 243 and the positioning groove 232, which are like magnetically repelling each other, overcome a little magnetic force and get closer to each other, thereby applying the magnetic force and elastic force to the limiting frame 51, so that the limiting frame 51 is more stable in the positioning groove 232 and the positioning opening 244;

[0054] Moreover, when the limiting frame 51 is separated from the positioning opening 244, the magnetic force and the elastic force cooperate to timely move the side mounting strip 243 in the positioning groove 232, so that the positioning opening 244 and the limiting frame 51 are staggered, so as to prevent the limiting frame 51 that should be separated from from being affected by the waves and then turning back to get stuck on the side mounting strip 243;

[0055] Moreover, when the driving member 53 drives the movable sleeve 241 to move upward, the repulsive magnetic force between the side mounting strip 243 and the positioning groove 232 is utilized to reduce the friction between the side mounting strip 243 and the positioning groove 232, thereby better helping the movable sleeve 241 to drive the ball head bearing 24, the swing rod 25 and the connected dielectric plate 26 to disengage.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
