Photovoltaic and photo-thermal integrated device

Abstract

This invention discloses a photovoltaic-thermal integrated device, relating to the field of photovoltaic-thermal technology, including a transposition device, a support device, a solar thermal device, a photovoltaic device, and a linkage component. In photovoltaic mode, the circulating fluid is first supplied to the heat-collecting cylinder, and then to the heat-collecting capillary tube in the heat-collecting component and the heat-conducting cylinder in the light-transmitting component. When sunlight shines on the solar panel on the transducer component, excess heat is generated, which is transferred to the circulating fluid in the heat-collecting capillary tube. The circulating fluid then carries away the excess heat, achieving a cooling function. The transposition bolts on the transposition component are manually unscrewed from the transposition locking holes. Then, the transposition pull plate drives the transducer rack to slide in the transposition base plate. The transducer rack drives the three-impeller to rotate, and the three-impeller drives the transducer locking plate to extend outward on the transducer chassis, achieving the locking function between the transducer chassis and the transposition base plate, thereby realizing the rapid installation function of the transducer component.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic and photothermal technology, and in particular to an integrated photovoltaic and photothermal device. Background Technology

[0002] Traditional photovoltaic panels generate a large amount of waste heat during power generation, which leads to an increase in their own temperature and a decrease in power generation efficiency. The single solar thermal mode only considers the utilization of thermal energy but ignores the utilization of solar energy. Neither of the two single modes can maximize the utilization of solar energy. Therefore, photovoltaic and solar thermal integrated equipment is needed to maximize the utilization of solar energy.

[0003] Existing photovoltaic (PV) and solar thermal integrated equipment generally operates in a simultaneous PV and solar thermal mode. While this mode maximizes solar energy utilization during periods of abundant sunlight, it can prevent the solar thermal equipment from reaching the desired temperature in low-sunlight conditions. Furthermore, the PV equipment may experience reduced efficiency due to shading by the solar thermal equipment. Current technologies also include modes that allow switching between PV and solar thermal modes, but this requires extensive rotation of both devices, making operation cumbersome. Therefore, a new PV-solar thermal integrated equipment is needed that can simultaneously improve the efficiency of both solar thermal and PV operations, quickly switch between PV and solar thermal modes, and facilitate rapid disassembly and replacement of solar panels, thus addressing the shortcomings of existing PV-solar thermal integrated equipment.

[0041] like Figure 12 As shown, in the linkage assembly 5, the two ends of the linkage sleeve 501 are in contact with the sides of the two support frames 202 respectively; the second locking block 502 is fixedly installed at both ends of the linkage sleeve 501 respectively; the second locking block 502 also engages with the support groove 203; the linkage shaft 503 is rotatably connected inside the linkage sleeve 501; the two linkage connectors 504 are fixedly installed at both ends of the linkage shaft 503 respectively; the linkage connectors 504 are inserted into the inside of the photothermal shaft 301.

[0042] Working principle of the invention: Figure 1The invention provides the usage methods and corresponding scenarios. The attitude control of the photovoltaic-thermal integrated equipment during operation is determined by the support device 2, the solar thermal device 3, and the photovoltaic device 4. The attitude of the support device 2 is determined by the solar thermal device 3, and the attitude of the solar thermal device 3 is determined by the photovoltaic device 4. Therefore, the photovoltaic device 4 is the core of the photovoltaic-thermal integrated equipment during operation.

[0043] Taking a preferred embodiment as an example, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the light intensity detector 201 at the lower end of the support frame 202 will first detect the light intensity. Then, the operator selects the corresponding mode based on the data from the light intensity detector 201. First, manually pull the first locking block 103 on the side of the indexing disk 102 out of the support groove 203 on the side of the support frame 202. Then, manually hold the indexing handle 101 to drive the indexing disk 102 to rotate, or use a motor to directly drive the indexing disk 102 on the indexing device 1 to rotate. The indexing disk 102 drives the photothermal shaft through the indexing slide column 104. When 301 rotates, the solar thermal shaft 301 drives the solar thermal device 3 and the photovoltaic device 4 to rotate as a whole, causing the positions of the solar thermal device 3 and the photovoltaic device 4 to be interchanged. At this time, the photovoltaic device 4 is located at the lower end of the solar thermal device 3, thereby realizing the conversion from photovoltaic mode to solar thermal mode. In solar thermal mode, sunlight shines through the convex lens 307 into the circulating liquid inside the heat-collecting cylinder 306, heating the circulating liquid. The heat is then carried away by the circulating liquid, realizing the solar thermal conversion function. When the suspension containing reflective particles is injected into the arc-shaped light-transmitting cover 302... In normal conditions, the arc-shaped light-transmitting cover 302 reflects sunlight onto the heat-collecting cylinder 306, further heating the circulating fluid inside. The heated fluid then enters the support column 204 of the support device 2 through a hose, and subsequently flows from the lower end of the support column 204 into the external heat storage device, thus providing auxiliary heating for the circulating fluid in the heat-collecting cylinder 306. In photovoltaic mode, the circulating fluid is first supplied to the heat-collecting cylinder 306, and then to the heat-collecting capillary 312 in the heat-collecting component 304 and the light-transmitting cover 302. In the heat-conducting cylinder 309 of the light component 303, when sunlight shines on the solar panel 416 on the energy transducer 403, excess heat is generated. This excess heat is transferred to the heat-collecting transparent plate 310 and the heat-collecting transparent box 311 of the heat-collecting component 304. Subsequently, the heat-collecting transparent box 311 heats the circulating liquid in the heat-collecting capillary 312. After heating, the circulating liquid enters the heat-conducting cylinder 309 through the elastic plug 313, and then enters the heat-collecting cylinder 306 from the heat-conducting cylinder 309, thereby achieving the cooling function.

[0044] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in photothermal mode, the transposition bolt 411 on the transposition assembly 402 is manually unscrewed from the transposition locking hole 412. Then, the transposition pull plate 413 drives the transducer rack 417 to slide in the transposition groove 414 of the transposition base plate 410. The transducer rack 417 then drives the three-impeller 419 to rotate. The three-impeller 419 drives the transducer locking plate 420 to extend outward on the transducer chassis 418, thereby realizing the connection between the transducer chassis 418 and the transposition base plate 410. The locking function between 0 and 0 enables the rapid installation of the transducer assembly 403; first, unscrew the locking bolts 405 on the locking clamp 404, then manually rotate the locking clamp 404 so that the transducer slider 407 can slide on the side of the transducer rail 408. Then, pull out the transducer assembly 402 and the transducer slider 407 together, and then manually flip the transducer bracket 409 and the transducer base plate 410 inside the transducer assembly 402 to flip the transducer. The orientation of the energy conversion component 403 is used to switch from solar thermal mode to photovoltaic solar thermal mode. In photovoltaic solar thermal mode, the suspension containing reflective particles in the arc-shaped light-transmitting cover 302 is extracted, and sunlight shines through the arc-shaped light-transmitting cover 302, the light-transmitting back plate 308 of the light-transmitting component 303, the heat-collecting transparent plate 310, and the heat-collecting transparent box 311 onto the energy conversion component 403 of the photovoltaic device 4. Subsequently, the solar panel 416 on the energy conversion component 403 converts light energy into electrical energy, realizing simultaneous solar thermal energy storage and photovoltaic power generation. When the locking nut 401 and the locking bolt 305 are tightened, the photovoltaic base 406, the light-transmitting back plate 308, and the heat-collecting transparent plate 310 will press against each other. The second locking blocks 502 at both ends of the linkage sleeve 501 are used to engage with the support groove 203. The linkage shaft 503 and the linkage connector 504 on the linkage component 5 are used for power transmission between the two solar thermal shafts 301.
