Description

Technical Field

[0001] The present invention relates to the technical field of wave energy collection and wave energy power generation system, and in particular to a multi-layer spherical wave energy collection device. Background Art

[0002] Seventy percent of the earth's surface is ocean, which contains endless energy. If we can make full use of marine resources, efficiently gather and transform wave energy, its development and utilization are very important to alleviate the energy crisis and reduce environmental pollution. The surging wave movement produces huge, eternal and environmentally friendly energy. If we can make full use of the kinetic energy of the waves and the wave energy of other water surfaces, the prospects for world energy will be quite broad and bright.

[0003] The existing tidal energy and wave energy collection methods include oscillating water column type, oscillating float type, pendulum type, nodding duck type and contraction ramp type. However, the existing collection methods have the following defects: the wave energy collection device has a complicated structure, which is easy to cause energy loss during the conversion process and has a low energy collection rate; the device installation cost is high, the construction period is long or the construction process is complicated and labor-intensive; the equipment parts are immersed in seawater for a long time, are severely corroded by seawater, and need to be replaced frequently; and the vibration frequency and amplitude of wave energy are required to be high. Summary of the invention

[0004] According to the above problems of existing wave energy power generation devices and the demand for offshore wave energy power generation, a multi-layer spherical wave energy collection device is provided. The device can rise and fall with the waves on the sea surface, thereby causing the small balls between the spherical layers to roll, realizing efficient conversion of wave energy and improving power generation efficiency; at the same time, it can make full use of wave energy and realize the collection and utilization of clean energy.

[0005] The technical means adopted by the present invention are as follows:

[0006] A multi-layer spherical wave energy collection device comprises: a multi-layer sphere, an energy storage device and a power generation device arranged inside the multi-layer sphere; wherein:

[0007] The multi-layer sphere comprises an upper sphere, a lower outermost sphere, a lower middle sphere and a lower innermost sphere;

[0008] The power generation device comprises a power generation pipeline, a copper film portion, a blank portion and a power generation ball arranged inside the power generation pipeline;

[0009] The energy storage device includes a rectifier bridge, a voltage-stabilizing capacitor and an energy storage battery.

[0010] Furthermore, the lower outermost sphere is connected to the upper sphere via a sealing thread to achieve sealing of the device.

[0011] Furthermore, there is a power generation pipeline with a diameter of 10 mm between each layer of spheres in the multi-layer spheres, wherein only one surface of the lower outermost layer of spheres and the lower innermost layer of spheres serves to construct the pipeline.

[0012] Furthermore, the power generation pipeline is divided into 6 parts according to the arc, each part is a copper film part, and the interval part between the copper film parts is a blank part.

[0013] Further, the copper film portion includes a first copper film, a second copper film, a third copper film, a fourth copper film, a fifth copper film and a sixth copper film, wherein the first copper film, the second copper film, the third copper film, the fourth copper film, the fifth copper film and the sixth copper film are all connected by wires.

[0014] Furthermore, a boss with a length of 10 mm is provided on the top of the power generation pipeline to fix the width of the pipeline.

[0015] Furthermore, the materials of the multi-layer spheres and bosses are both organic acrylic.

[0016] Furthermore, the material of the power generation ball is PTFE, the diameter is 8mm, and 24 power generation balls are arranged in each power generation pipeline.

[0017] Furthermore, the power-generating beads act as friction negative electrode materials during the power generation process. Compared with the copper film, the power-generating beads have extremely high electronegativity. During the contact with the copper film, they can obtain electrons due to the friction electrification effect, so that they have negative charges. When the two friction layers are separated, since the power-generating beads are non-metallic materials, they can bind electrons for a long time. When the power-generating beads contact other copper films, the charge balance can make the electrons transfer between the two positive electrode materials, generating an equal amount of current in the opposite direction to the electron transfer.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The multi-layer spherical wave energy collection device provided by the present invention can rise and fall with the waves on the sea surface, thereby causing the small balls between the spherical layers to roll, thereby achieving efficient conversion of wave energy and improving power generation efficiency; at the same time, it can fully utilize wave energy to achieve the collection and utilization of clean energy.

[0020] Based on the above reasons, the present invention can be widely promoted in the fields of wave energy collection and wave energy power generation system. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.

[0039] like Figure 1 As shown, the present invention provides a multi-layer spherical wave energy collection device, comprising: a multi-layer sphere, an energy storage device, and a power generation device arranged inside the multi-layer sphere; wherein:

[0040] The multi-layer sphere includes an upper sphere 7, a lower outermost sphere 8, a lower middle sphere 9 and a lower innermost sphere 10; Figure 2-Figure 5 As shown, the inner and outer diameters of the lower outermost sphere 8 are 95mm and 89mm respectively, the inner and outer diameters of the lower middle layer sphere 9 are 79mm and 74mm respectively, the inner and outer diameters of the lower innermost layer sphere 10 are 64mm and 59mm respectively, and the inner and outer diameters of the upper sphere 7 are 95mm and 89mm respectively.

[0041] The power generation device comprises a power generation pipeline, a copper film portion 1-X, a blank portion 2-X and a power generation ball 3 arranged inside the power generation pipeline 4;

[0042] The energy storage device includes a rectifier bridge 5, a voltage stabilizing capacitor and an energy storage battery 11. Figure 8 As shown, the energy storage part of the device is composed of a rectifier bridge 5, a voltage-stabilizing capacitor and a rechargeable lithium battery. Since the voltage of the power generation device is extremely unstable due to the fluctuation amplitude and frequency of the waves and the susceptibility to other external factors such as wind energy during the power generation process, the rectifier bridge 5 and the voltage-stabilizing capacitor are required to process the converted electric energy and then store it. Each pipeline constitutes an independent loop, and each independent loop is connected to a rectifier bridge 5, and finally the purpose of accumulating voltage is achieved by series connection.

[0043] In specific implementation, as a preferred embodiment of the present invention, the lower outermost sphere 8 is connected to the upper sphere 7 via a sealing thread 6 to achieve sealing of the device, wherein the sealing thread 6 has a thread height of 10 mm and a pitch of 1 mm.

[0044] In specific implementation, as a preferred embodiment of the present invention, there is a power generation pipeline 4 with a diameter of 10 mm between each layer of the multi-layer spheres, wherein only one surface of the lower outermost sphere 8 and the lower innermost sphere 10 serves to construct the pipeline. Figure 7 As shown, this figure only describes the whole process of power generation in a pipeline. In a complete power generation cycle, it can be divided into 4 stages. In this cycle, electrons are transferred between the power generation ball 3 and the copper film, and between two adjacent copper films through the two principles of frictional electricity generation and charge balance, and finally current is formed, voltage is generated, and the conversion between wave energy and electrical energy is realized.

[0045] In specific implementation, as a preferred embodiment of the present invention, the power generation pipeline is divided into 6 parts according to the arc, and each part is a copper film part 1-X, wherein the interval part between the copper film parts 1-X is a blank part 2-X.

[0046] In specific implementation, as a preferred embodiment of the present invention, the copper film portion includes a first copper film 1-1, a second copper film 1-2, a third copper film 1-3, a fourth copper film 1-4, a fifth copper film 1-5 and a sixth copper film 1-6, wherein the first copper film 1-1, the second copper film 1-2, the third copper film 1-3, the fourth copper film 1-4, the fifth copper film 1-5 and the sixth copper film 1-6 are all connected by a wire 12.

[0047] In specific implementation, as a preferred embodiment of the present invention, a boss with a length of 10 mm is provided on the top of the power generation pipeline to fix the width of the pipeline.

[0048] In specific implementation, as a preferred embodiment of the present invention, the materials of the multi-layer spheres and bosses are both organic acrylic.

[0049] When specifically implemented, as a preferred embodiment of the present invention, Figure 6As shown, the power generation ball 3 is made of PTFE with a diameter of 8 mm, and 24 power generation balls 3 are arranged in each power generation pipeline. The power generation ball 3 acts as a friction negative electrode material in the power generation process. Compared with the copper film, the power generation ball 3 has a very high electronegativity. In the process of contacting with the copper film, it can obtain electrons due to the friction electrification effect, so it has a negative charge. When the two friction layers are separated, since the power generation ball 3 is a non-metallic material, it can bind electrons for a long time. When the power generation ball 3 contacts other copper films, the charge balance can make the electrons transfer between the two positive electrode materials, generating a current of the same amount and opposite to the direction of the electron transfer.

[0050] The working principle of this device is as follows:

[0051] The following is an explanation of the power generation process in a sandwich power generation pipeline. When the device is impacted by waves on the sea surface, the power generation ball 3 will roll up and down in the corresponding pipeline. In this process, the copper molds 1-X are connected by copper wires 12. The power generation ball 3 will contact the first copper film 1-1 and the fourth copper film 1-4. Due to frictional electricity, the power generation ball 3 will have a sufficient amount of negative charge. When the power generation ball 3 leaves the first copper film 1-1 and the fourth copper film 1-4 to reach the second copper film 1-2 and the fifth copper film 1-5, due to the charge balance principle, the electrons will flow from the second copper film 1-2, the third copper film 1-3, the fifth copper film 1-5, and the sixth copper film 1-6 to the first copper film 1-1 and the fourth copper film 1-4 respectively, thereby generating charges in the circuit; when the power generation ball 3 contacts the second copper film 1-2 and the fifth copper film 1-5, the ball will be charged due to the frictional electricity principle, and then the cycle will repeat, so that the device converts wave energy into electrical energy. Due to the irregularity and low frequency of wave energy, the generated voltage will be unstable, so it needs to be rectified by the rectifier bridge 5. After being rectified by the rectifier bridge 5, the output voltage is not a true DC voltage, but a unidirectional pulsating voltage. Such a voltage has a change in intensity and will cause an impact on the energy storage battery. Therefore, a capacitor is needed to convert the unidirectional wave pulsating voltage into a uniform voltage. In this embodiment, an aluminum electrolytic capacitor with large capacity and good impact resistance is used. Finally, the converted electrical energy is used as follows Fig. 9 The energy storage battery 11 shown is used for storage for subsequent use by electrical appliances.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
