Description

Technical Field

[0001] The present invention relates to an offshore energy collection station, and particularly to a solar energy collection structure and an offshore multi-energy collection device capable of generating electricity through multi-excitation fusion and continuously supplying power. Background Art

[0002] The total area of the oceans on the earth accounts for about 71% of the total surface area of the earth. The oceans contain extremely rich resources. Based on the state of the saturation bottleneck of land resources, the importance of ocean resource development has become increasingly prominent, which has also prompted many countries to compete to layout the ocean energy strategy and seek to solve the energy shortage problem with advanced ocean technologies. At present, the development and utilization of resources in the ocean environment still rely on various ocean equipment. Such equipment also requires energy supply. It is obviously unrealistic to rely solely on the built-in energy storage battery of the equipment to supply power, which affects the working efficiency of the equipment. In view of the limitations of traditional power supply equipment, there is an urgent need for a device that can generate electricity by itself using the ocean environment and transmit energy externally. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a solar energy collection structure and an offshore multi-energy collection device. An offshore energy collection station capable of generating electricity through multiple channels and continuously supplying power.

[0004] A solar energy collection structure designed by the present invention includes a dish-shaped main board and a cover-shaped top cover. Convex lenses are arranged around the top cover. A mass block and a flexible piezoelectric material are arranged inside the top cover in a cooperative manner; the mass block is connected to the inner wall of the top cover through a plurality of spring-shaped shape memory alloys, and the flexible piezoelectric material is fixed on the dish-shaped main board through a bottom spring; the convex lenses are focused on the spring-shaped shape memory alloys; the dish-shaped main board is also cooperatively provided with a sleeve for accommodating the mass block, the flexible piezoelectric material and the bottom spring; the flexible piezoelectric material is connected to a storage battery.

[0005] Further, the opening size of the top cover is smaller than that of the dish-shaped main board. A plurality of solar panels are arranged on the dish-shaped main board at a position avoiding the top cover, and the solar panels are connected to the storage battery.

[0006] Further, at least 4 spring-shaped shape memory alloys are provided.

[0007] Further, the cross-sections of the mass block, the flexible piezoelectric material and the sleeve are all circular.

[0008] Based on the same inventive concept, the present invention also designs an offshore multi-energy harvesting device using a solar energy collection structure. The dish-shaped main board is a floating board with buoyancy and serves as the main body of the solar energy collection structure. The bottom of the dish-shaped main board is connected to a hollow lower main body. A bottom magnetic induction coil is provided at the bottom of the lower main body, and a floating permanent magnet is provided correspondingly. The floating permanent magnet is installed on a bundled mass block, and the bundled mass block is connected to the inner wall of the lower main body through a plurality of flexible cantilever beams; the bottom magnetic induction coil is connected to a storage battery.

[0009] Further, the thickness of the flexible cantilever beams is inconsistent, being thick near the bundled mass block and gradually thinning outward.

[0010] Further, piezoelectric sheets are provided on the flexible cantilever beams, and the piezoelectric sheets are connected to the storage battery.

[0011] Further, sliders are provided at the contact ends of the flexible cantilever beams with the inner wall of the lower main body. Slideways are provided on the inner wall of the lower main body, and the flexible cantilever beams are matched with the slideways through rollers installed on the sliders.

[0012] Further, floating magnetic induction coils are installed at the corresponding ends of the sliders and the lower main body, fixed permanent magnets matched with the floating magnetic induction coils are installed on the inner wall of the lower main body, and the floating magnetic induction coils are connected to the storage battery.

[0013] Furthermore, a boss is provided on the inner wall of the lower main body, and the fixed permanent magnet and the slideway are both installed on the boss.

[0014] The advantages of the present invention are as follows: Compared with the prior art, the present invention utilizes the piezoelectric effect and the Faraday effect to adopt multiple ways for energy harvesting, achieving multi-channel energy harvesting and greatly improving the efficiency of energy harvesting. By using the characteristic that the spring-shaped memory alloy deforms when heated, a convex lens is arranged on the side wall of the top cover at a certain angle with the horizontal plane. By selecting the focal length of the convex lens, after the spring-shaped memory alloy shrinks under the heating of the convex lens, it cannot continue to focus on the spring-shaped memory alloy. The initial state of the spring-shaped memory alloy is the state with the longest length. At this time, the spring-shaped memory alloy drives the frustum mass block to press the flexible piezoelectric material to generate voltage. After being heated by the convex lens, the length of the spring-shaped memory alloy shortens, driving the frustum mass block away from the flexible piezoelectric material. When the heating process is interrupted and the temperature drops, the spring-shaped memory alloy returns to its initial state, driving the frustum mass block to press the flexible piezoelectric material to generate electric energy. The bundled mass block is fixedly connected to the ends of four groups of cantilever beams and is restricted by them. When the sea water fluctuates, due to its own inertia, it drives the cantilever beams and the floating permanent magnet to vibrate and displace. The floating permanent magnet installed below the bundled mass block makes a vertical movement relative to the bottom magnetic induction coil, generating electric energy by using the Faraday effect. The cantilever beams are made of flexible materials and undergo elastic deformation under the action of the bundled mass block, driving the piezoelectric sheets to generate electricity. Moreover, their thicknesses are inconsistent, with a smaller thickness at the connection between the root and the slider and a larger thickness in the rest of the part, forming a stiffness difference, which can exacerbate the vibration of the cantilever beams to a certain extent and extend the service life of the mechanism. The slider is installed with rollers and can make a certain distance of horizontal movement under the drive of the cantilever beam and the restraint of the slideway. The floating magnetic induction coil installed at the tail makes a horizontal movement relative to the fixed permanent magnet under the action of the slider, further improving the efficiency of energy harvesting by using the Faraday effect.

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] This embodiment discloses a solar energy collection structure. As Figure 4 shown, this structure is used to collect solar energy and includes a dish-shaped main board 102 and a cover-shaped top cover 201. If the solar energy collection structure is used at sea, the dish-shaped main board is set as a floating board with buoyancy. Convex lenses 202 are arranged around the top cover 201, and a mutually cooperating mass block 204 and a flexible piezoelectric material 205 are arranged inside the top cover 201; the mass block 204 is connected to the inner wall of the top cover 201 through a plurality of spring-shaped shape memory alloys 203. In this embodiment, the number of spring-shaped shape memory alloys 203 is set to 4, corresponding to the convex lenses 202 one by one. The flexible piezoelectric material 205 is fixed on the dish-shaped main board 102 through a bottom spring 206; the convex lens 202 focuses on the spring-shaped shape memory alloy 203; the dish-shaped main board 102 is also provided with a sleeve 103 for accommodating the mass block 204, the flexible piezoelectric material 205 and the bottom spring 206; the number of bottom springs 206 can be set according to the specific implementation process. The flexible piezoelectric material 205 is connected to a storage battery.

[0025] To further increase the energy collection efficiency, the opening size of the top cover 201 is smaller than that of the dish-shaped main board 102, and a plurality of solar panels 101 are arranged on the dish-shaped main board 102 at positions avoiding the top cover. In this embodiment, the solar panels 101 are evenly arranged around the dish-shaped main board 102, and the solar panels 102 are connected to a storage battery.

[0026] In this embodiment, the preferred mode is that at least 4 spring-shaped shape memory alloys are provided. The cross-sections of the mass block 204, the flexible piezoelectric material 205 and the sleeve 103 are all circular.

[0027] As Figure 4Schematic diagram of the working of the disclosed solar energy collection structure. The spring-shaped shape memory alloy 203 is in its longest initial state. At this time, the spring-shaped shape memory alloy 203 drives the frustum-shaped mass block 204 to press the flexible piezoelectric material 205 to generate voltage. After being heated by the convex lens, the length of the spring-shaped shape memory alloy 203 shortens, driving the frustum-shaped mass block 204 away from the flexible piezoelectric material 205. When the heating process is interrupted and the temperature drops, the spring-shaped shape memory alloy 203 returns to its initial state, driving the frustum-shaped mass block 204 to press the flexible piezoelectric material 205 to generate electric energy. The flexible piezoelectric material 205 is fixedly connected to the dish-shaped floating plate 102 through the bottom spring 206, providing an installation margin for the overall solar energy collection device and facilitating the installation of the device. At the same time, the bottom spring 206 also squeezes the flexible piezoelectric material 205 from another direction.

[0028] Embodiment 2

[0029] Based on the same inventive concept, this embodiment also discloses an offshore multi-energy collection device using the solar energy collection structure. As shown in the appendix Figure 1 As shown, the device includes an upper energy collection device and a lower energy collection device. The upper energy collection device is the solar energy collection structure described in Embodiment 1. Since the structure and function thereof have been described in detail in Embodiment 1, they will not be elaborated here. When used for offshore energy collection, the dish-shaped main board is a floating plate. The lower energy collection device includes a lower main body 301, a bottom magnetic induction coil 302, and a floating permanent magnet 303. The lower main body 301 is integrally in a barrel-shaped structure. Both the dish-shaped main board 102 and the lower main body 301 are provided with bolt holes, and the two are connected by bolts. The top cover 201 and the dish-shaped main board 102 are installed in an interference fit manner through a card slot.

[0030] As Figure 2 shown, the overall explosion schematic diagram of the offshore multi-energy collection device further shows the assembly positions of the various components.

[0031] As Figure 3 shown, the explosion schematic diagram of the lower energy collection device details the internal assembly relationship of the lower energy collection device. A bottom magnetic induction coil 302 is provided at the bottom of the lower main body 301, and a floating permanent magnet 303 is provided therewith. The floating permanent magnet 303 is installed on the beam mass block 311. The beam mass block 311 is connected to the inner wall of the lower main body 301 through a plurality of flexible cantilever beams 309; the bottom magnetic induction coil 302 is connected to the storage battery. In this embodiment, the beam mass block 311 is fixedly connected to the ends of four groups of cantilever beams 309 at the same time. A slider 306 is provided at the contact end of the flexible cantilever beam 309 with the inner wall of the lower main body 301. A slideway 308 is provided on the inner wall of the lower main body 301 in a matching manner. The flexible cantilever beam 309 is matched with the slideway 308 through a roller 307 installed on the slider 306. A boss is provided on the inner wall of the lower main body 301, and the fixed permanent magnet 304 and the slideway 308 are both installed on the boss.

[0032] Preferably, to increase the power generation and further achieve multi-mode energy harvesting, a floating magnetic induction coil 305 is installed at the corresponding end of the slider 306 and the lower main body 301, and a fixed permanent magnet 304 cooperating with the floating magnetic induction coil 305 is installed on the inner wall of the lower main body 301. The floating magnetic induction coil 305 is connected to the storage battery.

[0033] When the sea water undulates, the bundled mass block 311 will drive the cantilever beam 309 and the floating permanent magnet 303 to vibrate and displace due to its own inertia. A piezoelectric sheet 310 is arranged on the flexible cantilever beam 309, and the piezoelectric sheet 310 is connected to the storage battery. Under the action of the bundled mass block 311, elastic deformation occurs to drive the piezoelectric sheet to generate electricity. The floating permanent magnet 303 installed below the bundled mass block 311 undergoes a vertical movement relative to the bottom magnetic induction coil 302, and electric energy is generated by using the Faraday effect.

[0034] As Figure 5 shown, the bundled mass block 311 is fixedly connected to the ends of four groups of cantilever beams 309 at the same time and is restricted by them. When the sea water undulates, due to its own inertia, it drives the cantilever beam 309 and the floating permanent magnet 303 to vibrate and displace. The floating permanent magnet 303 installed below the bundled mass block 311 undergoes a vertical movement relative to the bottom magnetic induction coil 302, and electric energy is generated by using the Faraday effect.

[0035] As Figure 6 shown, the thickness of the cantilever beam 309 is inconsistent. The thickness at the connection between the root and the slider 306 is smaller, showing a certain flexibility, and the thickness of the rest part is larger, forming a stiffness difference, which to a certain extent exacerbates the vibration of the cantilever beam and prolongs the service life of the mechanism.

[0036] The device further includes a storage battery. A piezoelectric sheet is pasted on the cantilever beam, and the piezoelectric sheet is electrically connected to the storage battery. The cantilever beam is made of a flexible material, such as 301 stainless steel thin plate, spring steel thin plate, aluminum alloy thin plate, etc., and is used to undergo elastic deformation under the action of an external force to drive the piezoelectric sheet to generate electricity.

[0037] The offshore multi-energy harvesting device in this embodiment utilizes the piezoelectric effect and the Faraday effect to adopt multiple ways for energy harvesting, achieving multi-channel energy harvesting and greatly improving the efficiency of energy harvesting. By using the characteristic that the spring-shaped shape memory alloy deforms when heated, a convex lens is arranged on the side wall of the top cover at a certain angle to the horizontal plane. By selecting the focal length of the convex lens, after the spring-shaped shape memory alloy is heated and shrinks by the convex lens, it cannot continue to focus on the spring-shaped shape memory alloy. The initial state of the spring-shaped shape memory alloy is the state with the longest length. At this time, the spring-shaped shape memory alloy drives the frustum-shaped mass block to press the flexible piezoelectric material to generate voltage. After being heated by the convex lens, the length of the spring-shaped shape memory alloy shortens, driving the frustum-shaped mass block away from the flexible piezoelectric material. When the heating process is interrupted and the temperature drops, the spring-shaped shape memory alloy returns to its initial state, driving the frustum-shaped mass block to press the flexible piezoelectric material to generate electric energy.

[0038] The bundled mass block is fixedly connected to the ends of four groups of cantilever beams and is restricted by them. When the sea water undulates, due to its own inertia, it drives the cantilever beams and the floating permanent magnet to vibrate and displace. The floating permanent magnet installed below the bundled mass block makes a vertical movement relative to the bottom magnetic induction coil, generating electric energy by using the Faraday effect. The cantilever beams are made of flexible materials and undergo elastic deformation under the action of the bundled mass block, driving the piezoelectric sheets to generate electricity. Moreover, their thicknesses are inconsistent, with a smaller thickness at the connection between the root and the slider and a larger thickness in the rest of the part, forming a stiffness difference to present flexibility, which can intensify the vibration of the cantilever beams to a certain extent and extend the service life of the mechanism. The slider is installed with rollers and can make a certain distance of horizontal movement under the drive of the cantilever beam and the restraint of the slideway. The floating magnetic induction coil installed at the tail makes a horizontal movement relative to the fixed permanent magnet under the action of the slider, further improving the efficiency of energy harvesting by using the Faraday effect.
