[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figures 1-18A photovoltaic and high-efficiency heat collection split-screen solar ball system based on flexible batteries includes a base 1, and a preheating component 2 and a light refraction component 3 are respectively provided on the surface of the base 1 from the outside to the inside. A bracket 4 is fixed at the center of the surface of the base 1, and the bracket 4 is rotatably connected to the sphere component 6 through a rotating shaft 503. The top of the bracket 4 drives the sphere component 6 to rotate through a driving component 5, and the sphere component 6 is respectively provided with a photovoltaic area and a photothermal area from top to bottom, and an insulation board 603 is provided between the photovoltaic area and the photothermal area; the photovoltaic area includes a transparent flexible photovoltaic panel 604, and the surface of the transparent flexible photovoltaic panel 604 is coated with an optical film for utilizing visible light and infrared light in different bands; the heat exchange medium first passes through the preheating component 2 for light preheating, and then passes into the photothermal area, and then the infrared light passes through the transparent flexible photovoltaic panel 604 to irradiate into the photothermal area for heat exchange of the medium, and the light refraction component 3 can further reflect light to the photothermal area to enhance heat exchange.

[0040] In this embodiment, the device can be used in scenarios such as civil or industrial and commercial use. Before use, the device is installed in an area with sufficient light, such as a roof. The base 1 can be poured with concrete to improve the stability of the device, and a spherical component 6 is provided on the bracket 4. Photovoltaic power generation is performed through the photovoltaic area on the top of the spherical component 6, and the photovoltaic area is composed of a number of transparent flexible photovoltaic panels 604. The single shape of the transparent flexible photovoltaic panel 604 can be a triangle or a trapezoid, etc., and an optical film is coated on the surface of the transparent flexible photovoltaic panel 604. The optical film can be made of ‌FTO (fluorine-doped tin oxide)‌ or ‌AZO (aluminum-doped zinc oxide)‌ film layer, which has both high infrared transmittance and conductivity. Among them, the visible light band (400-700 nm) maintains a high transmittance (>80%) to ensure the power generation efficiency of the photovoltaic area, while the infrared band (>1200 The transmittance of the transparent flexible photovoltaic panel 604 is greater than 85%, allowing infrared light to penetrate the photovoltaic panel directly to the photothermal area to be absorbed and heated. Since most of the infrared light is transmitted through the surface of the transparent flexible photovoltaic panel 604, the temperature of the transparent flexible photovoltaic panel 604 can be effectively reduced, ensuring its working efficiency and service life. By using a spectrum splitting method, photovoltaic and photothermal systems can be operated in a coordinated manner. Furthermore, a transparent protective shell 610 is installed on the outer surface of the photothermal zone. A heat dissipation gap 613 is provided between the transparent protective shell 610 and the transparent flexible photovoltaic panel 604 for dissipating heat from the photovoltaic zone. A heat preservation structure is formed between the transparent protective shell 610 and the heat insulation board 603 to retain heat from the photothermal zone. A "Z"-shaped rainproof structure is formed between the transparent protective shell 610 and the heat insulation board 603, and the spherical assembly 6 is tilted to accelerate drainage. Specifically, the transparent protective shell 610 is made of acrylic, which ensures light transmission while protecting the components inside the photothermal zone to prevent hail or other impurities from damaging the internal components. The heat insulation board 603 can prevent the heat from the photothermal zone from affecting the transparent flexible photovoltaic panel 604 above. It can also block the heat in the photothermal zone, thereby improving the heat exchange efficiency of the photothermal zone. The heat dissipation efficiency of the transparent flexible photovoltaic panel 604 can be accelerated through the heat dissipation slit 613, further ensuring that it is at a safe and efficient operating temperature. At the same time, the position of the heat dissipation slit 613 is in a "Z" shape in the cross-section state. The spherical component 6 is arranged at an angle, so that rainwater at the heat dissipation slit 613 will slide down the inclined surface and be discharged. At the same time, the spherical component 6 can be rotated by the driving component 5, thereby improving the operation efficiency of photovoltaic and solar thermal systems. The rotation mode can be a reciprocating 180° rotation, which reduces the risk of subsequent pipe and line entanglement and the difficulty of design. Among them, the line of the transparent flexible photovoltaic panel 604 can pass through the heat dissipation slit 613 and be connected to the external inverter and control cabinet, and finally transmit the electric energy to the power grid.

[0041] Reference Figure 2 and Figure 3 In a preferred embodiment, the preheating component 2 includes a double-layer preheating tube 201 that is spirally embedded in the surface of the base 1. Oil and water are respectively introduced into the double-layer preheating tube 201. A liquid inlet interface 202 is provided at one end of the double-layer preheating tube 201, and the surface of the double-layer preheating tube 201 is covered with a heat absorption protective plate 203.

[0042] Specifically, the double-layer preheating tube 201 is made of metallic copper, and is provided with independent oil and water channels inside. The oil channel is located outside the water channel. When light is irradiated on the heat-absorbing protective plate 203, light heat can be transferred to the double-layer preheating tube 201, thereby preheating the oil and water inside and improving the efficiency of subsequent light heat. The heat-absorbing protective plate 203 can be made of a metal material with high thermal conductivity, and the surface can be coated with a heat-absorbing coating to further improve the preheating effect. In other possible implementations, a phase-change heat storage material may be provided inside the base 1, which can absorb heat energy during the day and release heat energy at night, thereby providing heat for the double-layer preheating pipe 201 and preventing the pipe from freezing in winter.

[0043] Reference Figure 2 and Figure 3In a preferred embodiment, the light refraction component 3 includes a reflecting bracket 301 fixed to the surface of the base 1, and a reflecting lens 302 is arranged on the outer surface of the reflecting bracket 301. The reflecting lens 302 can refract and utilize part of the scattered light, thereby reflecting it from bottom to top to the outer surface of the photothermal area, and combining it with the light that passes through the photovoltaic area to the inner surface of the photothermal area, thereby achieving simultaneous photothermal treatment of the inner and outer surfaces of the photothermal area, effectively improving the photothermal efficiency, and a drain port 303 is provided at the bottom of the reflecting bracket 301, which can be used for drainage on rainy days.

[0044] Reference Figure 4-Figure 7 In a preferred embodiment, the spherical assembly 6 includes a longitudinal frame 601 rotatably arranged on the bracket 4, a transverse frame 602 is arranged in the top third area of ​​the longitudinal frame 601, a transparent flexible photovoltaic panel 604 is arranged at the position of the transverse frame 602, and a heat insulation board 603 is fixed on the inner side of the transverse frame 602, and a spiral heat exchange tube 606 or a straight heat exchange tube 609 is arranged on the inner side of the longitudinal frame 601.

[0045] Specifically, the transparent flexible photovoltaic panel 604 is arranged at the top third of the longitudinal frame 601, which can effectively reduce the contact amount of light reflected upward by the reflective lens 302, thereby preventing the transparent flexible photovoltaic panel 604 from overheating, and a spiral heat exchange tube 606 or a straight heat exchange tube 609 is arranged at the bottom two-thirds of the longitudinal frame 601, which can effectively receive the light reflected by the reflective lens 302 and the light passing through the transparent flexible photovoltaic panel 604.

[0046] Reference Figure 6-Figure 8 In a preferred embodiment, the spiral heat exchange tube 606 is fixed at the limiting groove 605 on the inner side of the longitudinal frame 601, and the spiral heat exchange tube 606 can be reinforced on the longitudinal frame 601 by a clamp. The straight heat exchange tubes 609 are arranged in a rectangular array in the support plate frame 608. The support plate frame 608 is arranged obliquely on the inner side of the longitudinal frame 601 through the support angle code 607 and is distributed in a circular array. The spiral heat exchange tube 606 and the straight heat exchange tube 609 are both located below the transparent flexible photovoltaic panel 604.

[0047] Specifically, whether the spiral heat exchange tube 606 or the straight heat exchange tube 609 is selected, its outer surface can be exposed to light. The spiral heat exchange tube 606 and the straight heat exchange tube 609 can be selectively implemented according to actual needs and budget costs. The straight heat exchange tube 609 has lower costs and lower process difficulty, but has a lower space efficiency. The spiral heat exchange tube 606 has higher costs and greater process difficulty, but has higher space utilization and better heat exchange effect. Regarding the assembly of the spiral heat exchange tube 606, the longitudinal frame 601 can be set to a detachable structure. First, assemble part of the longitudinal frame 601, then install the spiral heat exchange tube 606, and finally install the entire longitudinal frame 601 to form a wrapped fixation. Regarding the installation of the heat exchange straight tube 609, it can be pre-installed inside the support plate frame 608, and ensure that multiple heat exchange straight tubes 609 are interconnected. Then, the support plate frame 608 is inserted into the interior from the gap of the longitudinal frame 601, and the support plate frame is fixed through the support angle code 607. The upper and lower ends of 608 are fixed on the inner side of the longitudinal frame 601, and then all the liquid outlets of the support plate frames 608 are connected by pipes to realize the series connection of all the heat exchange straight tubes 609. When the spiral heat exchange tube 606 or the heat exchange straight tube 609 is assembled, the transparent protective shell 610 can be installed. The specific operation is: there are two groups of transparent protective shells 610, and the two groups of transparent protective shells 610 are spliced ​​and covered on the outer surface of the longitudinal frame 601 through fixed connectors 611. The overall installation operation is simple and convenient, and the structure is stable and reliable.

[0048] Further, such as Figure 9 As shown, a ring-shaped ridge 612 is provided on the top of the transparent protective shell 610, and the top of the ring-shaped ridge 612 is in contact with the lower surface of the insulation board 603, which can effectively prevent the heat from the photothermal area from passing through the insulation board 603 and entering the photovoltaic area.

[0049] In the above technical solution, in order to improve the heat exchange efficiency of the medium in the photothermal zone, the following structural design is made.

[0050] Specifically, such as Figure 18 As shown, the spiral heat exchange tube 606 and the straight heat exchange tube 609 are both composed of a metal inner tube Ba, a transparent outer tube Aa and a heat absorption layer Ca, which are distributed from the inside to the outside. Water can flow into the metal inner tube Ba, while oil can flow into the transparent outer tube Aa. The heat absorption layer Ca absorbs light and heat, first transferring the heat to the oil and then from the oil to the water, thereby improving the heat exchange efficiency while saving space.

[0051] Specifically, the first liquid inlet pipe 7 is composed of an outer first outer tube 701 and an inner first inner tube 702, the second liquid inlet pipe 8 is composed of an outer second outer tube 801 and an inner second inner tube 802, and the liquid discharge pipe 9 is composed of an outer third outer tube 901 and an inner third inner tube 902.

[0052] Among them, oil is introduced into the first outer tube 701, the second outer tube 801 and the third outer tube 901, while water is introduced into the first inner tube 702, the second inner tube 802 and the third inner tube 902, and the liquid outlet end of the double-layer preheating tube 201 is rotatably connected to the first liquid inlet pipe 7, the liquid outlet end of the first liquid inlet pipe 7 is connected to the liquid inlet end of the spiral heat exchange tube 606 or the heat exchange straight tube 609, and the liquid outlet end of the spiral heat exchange tube 606 or the heat exchange straight tube 609 is connected to the discharge pipe 9 through the second liquid inlet pipe 8.

[0053] In the above technical solution, considering that the ball assembly 6 of the present application can rotate, in order to ensure the connectivity between the pipelines, the specific structure is as follows.

[0054] Specifically, such as Figure 12-16 As shown, the first outer tube 701 is rotatably connected to the oil path inside the double-layer preheating tube 201 via a sealed bearing, and the first inner tube 702 is rotatably connected to the water path inside the double-layer preheating tube 201 via a sealed bearing. The double-layer preheating tube 201 passes through the hollow rotating shaft 503 at the bottom of the bracket 4 and is rotatably connected to the first outer tube 701 and the first inner tube 702, ensuring that when the ball assembly 6 and the first liquid inlet tube 7 rotate together, the double-layer preheating tube 201 remains stationary.

[0055] Specifically, the liquid inlet end of the metal inner tube Ba is connected to the first inner tube 702, the liquid inlet end of the transparent outer tube Aa is connected to the first outer tube 701, the liquid outlet end of the metal inner tube Ba is connected to the second inner tube 802, and the liquid outlet end of the transparent outer tube Aa is connected to the second outer tube 801; the liquid outlet end of the second inner tube 802 is connected to the third inner tube 902, and the liquid outlet end of the second outer tube 801 is connected to the third outer tube 901, ensuring that the internal pipelines of the spherical assembly 6 are interconnected, and the oil circuit and the water circuit are correspondingly connected without interfering with each other.

[0056] Specifically, the liquid outlet end of the third inner tube 902 is connected to the first rotary connector 10 through a sealed bearing, and the liquid outlet end of the third outer tube 901 is connected to the second rotary connector 11 through a sealed bearing. The drain pipe 9 passes through the hollow shaft 503 at the upper end of the bracket 4 as a whole. The first rotary connector 10 is located above the second rotary connector 11, and a through opening is opened on the surface of the second rotary connector 11 for the liquid outlet end of the third inner tube 902 to pass through, thereby ensuring that the liquid outlet end of the third inner tube 902 can be connected to the first rotary connector 10. When the ball assembly 6 rotates, the shaft 503 and the drain pipe 9 will rotate, but the first rotary connector 10 and the second rotary connector 11 will remain stationary, wherein the first rotary connector 10 is used to discharge water, and the second rotary connector 11 is used to discharge oil.

[0057] Reference Figure 13 In a preferred embodiment, the driving assembly 5 includes a motor 501 fixed to the top of the bracket 4, and the output end of the motor 501 is fixedly connected to the driving gear 502, which is engaged with the driven gear 504 on the outer surface of the rotating shaft 503. The motor 501 can drive the driving gear 502, the driven gear 504, the rotating shaft 503 and the longitudinal frame 601 to rotate.

[0058] Reference Figures 8-10In a preferred embodiment, a small air pump 12 is installed on the surface of the insulation board 603, and the air outlet end of the small air pump 12 is connected to the air inlet 13 of the longitudinal frame 601. The longitudinal frame 601 and the transverse frame 602 are both hollow structures and are interconnected. An exhaust port 14 is opened on the lower surface of the transverse frame 602, and the exhaust port 14 is facing the direction of the heat dissipation seam 613.

[0059] Specifically, in order to ensure that the transparent flexible photovoltaic panel 604 is always at a safe operating temperature, the existing capillary heat dissipation technology can be used to arrange transparent capillaries on the back of the transparent flexible photovoltaic panel 604 for water cooling and heat dissipation. The capillary tubes and the supporting circulation pump and other parts are not shown in the figure. The circulation pump and other parts can be arranged on the surface of the insulation board 603. At the same time, with the small air pump 12 designed in this application, air flow can be introduced into the longitudinal frame 601 and the transverse frame 602 of the hollow structure, and ejected from the exhaust port 14 opened on the lower surface of the transverse frame 602, thereby cooling the heat on the back of the transparent flexible photovoltaic panel 604. At the same time, the capillary tubes can also be air-cooled, and the ejected heat dissipation air flow can be discharged from the heat dissipation slit 613 (such as Figure 9 and Figure 10 ), effectively improving the overall heat dissipation efficiency.

[0060] Reference Figure 1 In a preferred embodiment, the liquid outlet of the first rotary connector 10 is connected to a four-way pipe 15 through a pipeline. The three liquid outlets of the four-way pipe 15 are respectively connected to a stepped hot water storage tank 17 through a solenoid valve 16. The three liquid outlets of the stepped hot water storage tank 17 are respectively connected to a four-way valve 19 through a first connecting pipe 18. The liquid outlet of the four-way valve 19 is connected to a heat pump 20. The stepped hot water storage tank 17 is divided into three independent liquid storage areas from bottom to top, namely a high-temperature liquid storage area, a medium-temperature liquid storage area, and a low-temperature liquid storage area. Specifically, the water source discharged through the first rotary connector 10 can be passed through the pump into the cascade heat storage tank 17 for storage, and the water outlet end of the first rotary connector 10 can be equipped with a temperature sensing module for detecting the temperature of the discharged water source, and equipped with a controller to control the opening and closing of the corresponding solenoid valve 16 to achieve classified storage of water sources of different temperatures. For example, when the temperature sensing module detects that the outlet water temperature is above 80 degrees, the controller controls the solenoid valves 16 of the medium-temperature liquid storage area and the low-temperature liquid storage area to close, and the solenoid valve 16 of the high-temperature liquid storage area to open, so as to pass the high-temperature water into the high-temperature liquid storage area for storage. Similarly, water sources of 50-80 degrees are stored in the medium-temperature liquid storage area, and water sources below 50 degrees are stored in the low-temperature liquid storage area. In this way, cascade heat storage can be achieved, and with the four-way valve 19 and the heat pump 20, different water needs can be met. It is worth noting that the cascade water storage tank 17 needs to be equipped with a pressure relief valve to avoid safety hazards caused by excessive internal pressure, and the three temperature storage areas of the cascade water storage tank 17 are isolated by an insulation layer to prevent heat from being conducted to each other. If there is insufficient light such as on cloudy days, the heat pump 20 can assist in heating the water source to the specified temperature for use.

[0061] Furthermore, the liquid outlet end of the second rotary connector 11 is connected to an oil storage tank 21. The oil body after the photothermal heating of this application can be stored in the subsequent oil storage tank 21 for industrial heating. This application can select different heat exchange media according to the usage scenario to meet different usage requirements. The double-layer preheating tube 201 is not limited to water and oil. The other heat exchange media should fall within the protection scope of this application if it can be implemented.

[0062] Furthermore, the high-temperature liquid storage area of ​​the stepped water storage tank 17 is connected to the electrolytic cell 23 and the hydrogen storage tank 24 through the second connecting pipe 22. The present application can also use photothermal technology to heat ultrapure water, thereby meeting the conditions for industrial hydrogen production and enriching the functionality of the present application. The hydrogen production technology is an existing technology and will not be repeated here.

[0063] The spiral heat exchange tube 606 and the straight heat exchange tube 609 in the above technical solution are only two of the preferred implementation methods of this application. In actual production and use, they can be selectively replaced according to the production difficulty and cost budget, such as replacing them with existing heat exchange products such as vacuum collector tubes and plate heat exchangers. Such conventional technical replacements are also within the scope of protection of this application. As for the pipeline connection method, it can be improved by conventional means, which will not be repeated here.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
