Description

Technical Field

[0001] The present invention relates to the technical field of self-generating energy storage equipment, and in particular to a thermoelectrically coupled photovoltaic energy storage device. Background Art

[0002] In recent years, with the rapid development of renewable energy technology, photovoltaic power generation systems have attracted widespread attention due to their clean and sustainable characteristics. However, traditional photovoltaic power generation technology has low conversion efficiency through light energy, high initial investment costs, and a long payback period. In addition, photovoltaic power generation technology has obvious limitations. Its power generation efficiency is directly related to the intensity and duration of light. Its power generation capacity decreases significantly at night or in low light conditions. The temperature generated by photovoltaic equipment during sunlight and daily operation is not effectively utilized, resulting in energy waste.

[0003] To address the issue of utilizing the heat energy generated by photovoltaic power generation, phase change energy storage material (PCM) technology has been introduced to improve the overall energy efficiency of the system. Organic phase change materials such as paraffin are widely used due to their high latent heat value and good chemical stability. However, in actual applications, they still suffer from the problem of poor matching between the phase change temperature and the external environment, resulting in a rapid heat release rate. In addition, while thermoelectric conversion technology can achieve direct heat-to-electricity conversion, its power generation efficiency is significantly reduced in scenarios where the temperature difference between day and night is insufficient or the heat source is unstable. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the present invention provides a thermoelectrically coupled photovoltaic energy storage device, which has the advantages of being able to synergistically utilize multiple energy sources and improve the durability and efficiency of power generation. It solves the problems of the phase change materials currently used to achieve thermoelectric coupled power generation being affected by weather and day and night temperature differences, resulting in low power generation efficiency, fast heat source release efficiency, and poor stability.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a thermoelectrically coupled photovoltaic energy storage device, comprising an energy storage box, a thermoelectric box, a solution box, a power generation box, and auxiliary components. The thermoelectric box is fixed to the energy storage box and is used to convert absorbed thermal energy into electrical energy and store it in the energy storage box. The energy storage box is equipped with multiple groups of batteries for storing the electrical energy converted from photovoltaic power generation and thermal power generation.

[0008] A solution box is fixed on the thermoelectric box, which is used to store organic phase change materials and release heat energy for a long time. The solution box is filled with organic phase change materials, specifically modified paraffin. By adjusting the carbon chain length, such as C18-C20, the melting point can be controlled within the range of 25-30°C. By relying on external radiation and temperature increase, the paraffin melts after reaching the melting point, and the temperature is continuously transmitted to the thermoelectric box below. The thermoelectric box converts heat energy into electrical energy and stores it in the energy storage box.

[0009] A generator box is installed on the solution box. The generator box consists of a bottom plate, a guard plate and a top plate. The guard plate is fixed to the edge between the bottom plate and the top plate, and the bottom plate is fixed on the solution box. At the same time, an interface connected to the solution box is provided on the bottom plate. Phase change material can be transported into the solution box or withdrawn and replaced through the interface. At the same time, a sealing cover is installed on the interface. The sealing cover seals the interface to prevent liquid from flowing out. When the temperature reaches the melting point, the phase change material in the solution box melts, gradually heats up to store heat energy, and transfers the temperature to the thermoelectric box.

[0010] A strip frame is fixed on the bottom plate, and a friction plate 1 is fixed inside the strip frame. At the same time, a moving frame is slidably connected to the strip frame, and a friction plate 2 is fixed at the bottom of the moving frame. The friction plate 2 is attached to the friction plate 1, and the moving frame slides inside the strip frame, so that the friction plate 2 and the friction plate 1 rub repeatedly, causing the bottom plate to heat up quickly and transfer the temperature to the solution box, thereby extending the cooling time of the phase change material and allowing the phase change material to continuously provide temperature to the thermoelectric box.

[0011] A photovoltaic panel connected to the generator box is rotatably connected to the top plate, and a lens plate is flexibly mounted on it. An auxiliary component is fixed to the bottom of the lens plate, which uses wind energy to drive friction plate 2 and friction plate 1 to generate heat through friction. Three slots are evenly spaced on the top plate. The slots on both sides rotatably connect the photovoltaic panel, while the central slot flexibly mounts the lens plate. The photovoltaic panel is a translucent perovskite solar film with high light transmittance, which can directly illuminate the bottom plate, causing it to heat up rapidly and transfer the heat to the solution box.

[0012] As a further improvement of the above solution, a stabilizing rod is fixed in the guard plate, and the stabilizing rod passes through the strip frame and the movable frame.

[0013] The side of the stabilizing rod is movably sleeved with a tension spring, and two ends of the tension spring are fitted between the bar frame and the movable frame.

[0014] Through the above technical solution, the width of the moving frame is consistent with the width of the strip frame, which improves the sliding stability of the moving frame. When sliding, the moving frame repeatedly moves on the side of the stabilizing rod, further improving the stability of the moving frame displacement and preventing the moving frame from escaping from the strip frame.

[0015] As a further improvement of the above solution, multiple ceramic panels and thermoelectric films are movably connected in the thermoelectric box, multiple ceramic panels and thermoelectric films are cross-stacked, and positioning screws are threadedly connected to the ceramic panels and thermoelectric films. At the same time, the thermoelectric films are connected to the power generation box.

[0016] Through the above technical solution, the ceramic panel can store the received temperature for a long time, so that it can continuously provide temperature to the thermoelectric film at night or in cold weather, and convert thermal energy into electrical energy through the thermoelectric film and store it in the energy storage box.

[0017] As a further improvement of the above solution, a connecting rod is fixed to the bottom of the lens plate, and a limiting plate is fixed to the bottom of the connecting rod. The limiting plate is flush with the top plate at a set height.

[0018] Through the above technical solution, the lens plate adopts a concave mirror, which receives light energy and diffuses the light energy onto the bottom plate, causing the bottom plate to heat up quickly.

[0019] As a further improvement of the above solution, an adjustment control unit is installed on the side of the generator box. The adjustment control unit includes a drive box fixed on the side of the guard plate, and a connecting plate fixed on the side of the top plate. A lifting rod is fixed at the bottom of the connecting plate, and the lifting rod is movably sleeved in the drive box.

[0020] A motor is fixed to the side of the driving box, a driving gear is fixed to the output end of the motor, and the driving gear is meshed with the side of the lifting rod.

[0021] Through the above technical solution, a circular hole is passed through the drive box, and the diameter of the lifting rod matches the inner diameter of the circular hole. Through the operation of the motor, the output end drives the driving gear to rotate forward and reverse, and the meshing force is used to make the lifting rod drive the connecting plate to rise and fall, thereby realizing the height displacement change of the top plate. When the top plate rises to a certain height, the auxiliary part is in contact with the outside world, and when the top plate drops to the limit, the auxiliary part is retracted into the generator box.

[0022] As a further improvement of the above solution, a traction member is installed on the connecting plate, and the traction member includes a traction box fixed on the connecting plate, and rotating rollers are rotatably connected to both ends of the traction box.

[0023] An adjustment groove is provided on the photovoltaic panel, a moving block is slidably connected in the adjustment groove, and a connecting block is fixed on the moving block.

[0024] A traction rope is movably connected between the rotating roller and the connecting block.

[0025] Both ends of the traction rope are fixed with screw buttons, which are respectively threadedly connected to the rotating roller and the connecting block.

[0026] Through the above technical solution, the connecting plate drives the traction part to change in height displacement synchronously. When rising, the connecting block is pulled by the traction rope to tilt the photovoltaic panel. The tilt angle of the photovoltaic panel is used to guide the wind into the generator box and blow it to the auxiliary parts.

[0027] As a further improvement of the above solution, protective nets are fixed to the top and bottom of the roof, and the protective nets are attached to the surface of the photovoltaic panel.

[0028] Through the above technical solution, the protective net is an elastic net, which is installed at the top and bottom of the trough body connected to the top plate by the photovoltaic panel. When the photovoltaic panel rotates and tilts, the protective net is unfolded and covers the unfolded trough body to prevent sand and gravel from entering the generator box.

[0029] As a further improvement of the above solution, an adjusting screw is rotatably connected in the adjusting groove, and the adjusting screw is threadedly connected in the moving block.

[0030] Through the above technical solution, the position of the moving block in the adjustment slot can be adjusted by rotating the adjustment screw in the forward and reverse directions, thereby ensuring the consistency of the inclination angle of the photovoltaic panel when replacing traction ropes of different lengths and when the height displacement of the traction box changes.

[0031] As a further improvement of the above solution, the auxiliary component includes a support rod fixed to the bottom of the lens plate, and a rotating mechanism is installed on the support rod.

[0032] The rotating mechanism includes a bevel gear rotatably connected to the bottom end of the support rod, a special-shaped rod fixed at the bottom of the bevel gear, a sleeve movably sleeved on the side of the special-shaped rod, and a toothless gear fixed at the bottom end of the sleeve.

[0033] A tooth profile is provided on the inner side of the moving frame, and the toothless gear is engaged with the tooth profile.

[0034] Through the above technical solution, the support rod is cross-shaped, the branch at the top of the support rod is fixed to the bottom of the lens plate, and the bevel gear in the rotating mechanism is connected to the branch at the bottom end of the support rod. When the bevel gear rotates, it drives the special-shaped rod to rotate at the same time, so that the sleeve drives the toothless gear to rotate. Under the meshing force of the toothless gear and the tooth profile, the moving frame is able to slide in the bar frame.

[0035] As a further improvement of the above solution, the auxiliary component also includes two sets of rotating mechanisms installed on the side of the support rod.

[0036] The rotating mechanism comprises a second bevel gear rotatably connected to the side of the support rod, a rotating rod is fixed on the second bevel gear, and a fan blade is fixed on one end of the rotating rod.

[0037] Through the above technical solution, bevel gear 2 is installed on the branches at the opposite ends of the support rod, and a rotating rod is installed on the bevel gear 2. A fan blade is installed at the front end of each rotating rod. The natural wind blows the fan blade, so that the rotating rod drives the bevel gear 2 to rotate.

[0038] As a further improvement of the above solution, the bevel gear 1 is meshed with the bevel gear 2.

[0039] Through the above technical solution, when the bevel gear 2 rotates, the meshing force drives the bevel gear 1 to rotate, thereby causing the toothless gear to rotate.

[0040] Compared with the prior art, the present invention provides a thermoelectric coupled photovoltaic energy storage device with the following features:

[0041] Beneficial effects:

[0042] 1. This thermoelectrically coupled photovoltaic energy storage device utilizes photovoltaic power generation. The temperature generated by partial light transmission and the operation of the photovoltaic panel itself is introduced into the power generation box, causing the bottom plate to heat up. After the phase change material in the solution box is melted, the heat energy is concentrated and accumulated, and continuously transferred to the thermoelectric box at the bottom. Through the stacked design of the multi-layer ceramic panel and the thermoelectric film inside the thermoelectric box, the ceramic panel absorbs the heat and stores the heat energy, improving the stability of heat energy release and avoiding rapid release. In this way, the thermoelectric film is continuously heated during the day and night, and the thermoelectric film continuously converts temperature into electrical energy, thereby improving the thermal energy utilization rate and power generation efficiency.

[0043] 2. This thermoelectrically coupled photovoltaic energy storage device controls the rise of the lens plate so that the auxiliary parts are in contact with the outside world, thereby using wind energy to blow the fan blades to rotate. Under the transmission and cooperation of various connecting parts, the movable frame moves back and forth in the bar frame, and the friction plates rub against each other, causing the bottom plate to heat up rapidly. Therefore, it can still stably and continuously supply heat to the thermoelectric box even at night or in low light conditions, further improving the thermal energy utilization rate, power generation efficiency and stability.

[0044] 3. The thermoelectrically coupled photovoltaic energy storage device, while rising through the lens plate, pulls the photovoltaic panel through the traction rope, so that the photovoltaic panels on both sides are tilted toward the auxiliary part, thereby guiding the wind energy to blow toward the auxiliary part. In addition, through the design of two sets of opposite-direction fan blades, the utilization rate of wind energy is effectively improved, and the practicality and diversity of the device are improved.

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0067] Example 1

[0068] See also Figure 1 and Figure 4-13 As shown, a thermoelectric coupled photovoltaic energy storage device proposed in this embodiment includes an energy storage box 1, a thermoelectric box 2, a solution box 3, a power generation box 4 and an auxiliary component 5. The thermoelectric box 2 is fixed on the energy storage box 1 and is used to convert the absorbed thermal energy into electrical energy and store it in the energy storage box 1. Multiple groups of batteries are installed in the energy storage box 1 to store the electrical energy converted from photovoltaic power generation and thermal power generation.

[0069] A solution box 3 is fixed on the thermoelectric box 2, which is used to store organic phase change materials and release heat energy for a long time. The solution box 3 is filled with organic phase change materials, specifically modified paraffin. By adjusting the carbon chain length such as C18-C20, the melting point can be controlled within the range of 25-30°C. By relying on external radiation and temperature increase, the paraffin melts after reaching the melting point, and the temperature is continuously transmitted to the thermoelectric box 2 below, and the thermal energy is converted into electrical energy through the thermoelectric box 2 and stored in the energy storage box 1.

[0070] It should be further explained that the latent heat value of modified paraffin wax is as high as about 150-250 J / G, which can store and release heat for a long time, and has high chemical stability, is non-toxic, and has low cost.

[0071] In addition, in addition to modified paraffin wax, other organic phase change materials can be used as long as they can reach the melting point under normal natural radiation and temperature, and no limitation is made here.

[0072] A power generation box 4 is installed on the solution box 3. The power generation box 4 consists of a bottom plate 41, a guard plate 42 and a top plate 43. The guard plate 42 is fixed to the edge between the bottom plate 41 and the top plate 43, and the bottom plate 41 is fixed on the solution box 3. At the same time, an interface 411 connected to the solution box 3 is provided on the bottom plate 41. Phase change material can be transported into the solution box 3 or extracted and replaced through the interface 411. At the same time, a sealing cover is installed on the interface 411, and the sealing cover seals the interface 411 to prevent liquid from flowing out. When the temperature reaches the melting point, the phase change material in the solution box 3 melts, gradually heats up to store heat energy, and transfers the temperature to the thermoelectric box 2.

[0073] A strip frame 412 is fixed on the bottom plate 41, and a friction plate 1 413 is fixed inside the strip frame 412. At the same time, a movable frame 414 is slidably connected inside the strip frame 412, and a friction plate 2 415 is fixed at the bottom of the movable frame 414. The friction plate 2 415 is attached to the friction plate 1 413. The movable frame 414 slides inside the strip frame 412, so that the friction plate 2 415 and the friction plate 1 413 are repeatedly rubbed, so that the bottom plate 41 is quickly heated up and the temperature is transferred to the solution box 3, thereby extending the cooling time of the phase change material and allowing the phase change material to continuously provide temperature to the thermoelectric box 2.

[0074] It should be further explained that friction plate 1 413 and friction plate 2 415 are made of polymer and composite materials, such as iglidur series materials AC500, H3, polyphenylene sulfide, and thermoplastic polyurethane, which can achieve the effect of rapid heating and generating heat under floor friction, so that the bottom plate 41 can heat up quickly.

[0075] A photovoltaic panel 431 connected to the generator box 4 is rotatably connected to the top plate 43, and a lens plate 432 is movably sleeved thereon. An auxiliary part 5 is fixed to the bottom of the lens plate 432, which is used to drive the friction plate 2 415 and the friction plate 1 413 to generate heat through friction through wind energy. Three slots are equidistantly provided on the top plate 43, wherein the photovoltaic panels 431 are rotatably connected to the slots on both sides, and the lens plate 432 is movably sleeved thereon. The photovoltaic panel 431 is specifically a translucent perovskite solar film panel with high light transmittance, which can directly irradiate part of the light source on the bottom plate 41, causing it to heat up quickly and transfer the temperature to the solution box.

[0076] Furthermore, a stabilizing rod 421 is fixed in the guard plate 42 , and the stabilizing rod 421 passes through the bar frame 412 and the movable frame 414 .

[0077] A tension spring 422 is movably sleeved on the side of the stabilizing rod 421 , and both ends of the tension spring 422 are fitted between the bar frame 412 and the movable frame 414 .

[0078] More specifically, the width of the movable frame 414 matches the width inside the bar frame 412, thereby improving the sliding stability of the movable frame 414. When sliding, the movable frame 414 repeatedly shifts on the side of the stabilizing rod 421, thereby further improving the displacement stability of the movable frame 414 and preventing the movable frame 414 from escaping from the bar frame 412.

[0079] Furthermore, multiple ceramic panels 21 and thermoelectric films 22 are movably connected in the thermoelectric box 2, and the multiple ceramic panels 21 and thermoelectric films 22 are cross-stacked, and positioning screws 23 are threadedly connected to the ceramic panels 21 and the thermoelectric films 22, and the thermoelectric films 22 are connected to the power generation box 4.

[0080] More specifically, the ceramic panel 21 can store the received temperature for a long time, thereby continuously providing temperature to the thermoelectric film 22 at night or in cold weather, and converting thermal energy into electrical energy through the thermoelectric film 22 and storing it in the energy storage box 1.

[0081] It should be further explained that the thermoelectric film 22 generates electricity based on the Seebeck effect temperature difference, converting the received temperature into electrical energy.

[0082] Furthermore, a connecting rod 433 is fixed to the bottom of the lens plate 432 , and a limiting plate 434 is fixed to the bottom of the connecting rod 433 . The limiting plate 434 is flush with the top plate 43 at a set height.

[0083] More specifically, the lens plate 432 uses a concave mirror to receive light energy and diffuse the light energy onto the bottom plate 41, causing the bottom plate 41 to heat up quickly.

[0084] At the same time, the sizes of the lens plate 432 and the limit plate 434 match, and the lens plate 432 moves upward until the limit plate 434 is flush with the top plate 43, thereby sealing the groove body of the lens plate 432 on the top plate 43 to prevent dust from falling into the generator box 4.

[0085] Furthermore, an adjustment control unit 44 is installed on the side of the generator box 4. The adjustment control unit 44 includes a drive box 441 fixed to the side of the guard plate 42, and a connecting plate 442 fixed to the side of the top plate 43. A lifting rod 443 is fixed at the bottom of the connecting plate 442, and the lifting rod 443 is movably sleeved in the drive box 441.

[0086] A motor 444 is fixed to the side of the driving box 441 , a driving gear 445 is fixed to the output end of the motor 444 , and the driving gear 445 is engaged with the side of the lifting rod 443 .

[0087] More specifically, a circular hole is passed through the drive box 441, and the diameter of the lifting rod 443 matches the inner diameter of the circular hole. Through the operation of the motor 444, the output end drives the driving gear 445 to rotate forward and reverse. By utilizing the meshing force, the lifting rod 443 drives the connecting plate 442 to rise and fall, thereby realizing the height displacement change of the top plate 43. When the top plate 43 rises to a certain height, the auxiliary component 5 is in contact with the outside world, and when the top plate 43 drops to the limit, the auxiliary component 5 is retracted into the generator box 4.

[0088] The working principle of the thermoelectric coupling photovoltaic energy storage device proposed in this embodiment is as follows: during the day, the photovoltaic panel 431 absorbs sunlight, converts light energy into electrical energy and stores it in the energy storage box 1. At the same time, part of the light source passes through the photovoltaic panel 431 and the lens plate 432 and irradiates the bottom plate 41, so that after the bottom plate 41 is heated, the heat is transferred to the solution box 3, causing the organic phase change material inside to melt, and the heat energy is continuously transferred to the thermoelectric box 2, so that after the internal ceramic panel is heated, the temperature is stored, and at the same time, heat energy is continuously provided to the thermoelectric film 22, so that after the thermoelectric film 22 receives the heat energy, it converts the heat energy into electrical energy and stores it in the energy storage box 1.

[0089] Example 2

[0090] See also Figure 1-Figure 4 and Figure 7 As shown, the thermoelectric coupled photovoltaic energy storage device proposed in this embodiment, based on the first embodiment, further includes: a traction member 45 is installed on the connecting plate 442, and the traction member 45 includes a traction box 451 fixed on the connecting plate 442, and rotating rollers 452 are rotatably connected to both ends of the traction box 451.

[0091] An adjustment slot 4311 is formed on the photovoltaic panel 431 . A moving block 4312 is slidably connected in the adjustment slot 4311 . A connecting block 4313 is fixed on the moving block 4312 .

[0092] A traction rope 453 is movably connected between the rotating roller 452 and the connecting block 4313 .

[0093] Screw buttons 4531 are fixed at both ends of the traction rope 453 and are threadedly connected to the rotating roller 452 and the connecting block 4313 respectively.

[0094] More specifically, the connecting plate 442 drives the traction member 45 to change its height displacement synchronously. When rising, the connecting block 4313 is pulled by the traction rope 453 to tilt the photovoltaic panel 431. The tilt angle of the photovoltaic panel 431 is used to guide the wind into the generator box 4 and blow it onto the auxiliary member 5.

[0095] It should be further explained that photovoltaic panels 431 are installed on the top plate 43 and on both sides of the lens plate 432. An adjustment groove 4311 is provided on the top of the two groups of photovoltaic panels 431 away from the end of the lens plate 432. When the height displacement of the traction member 45 changes, the opposite outer sides of the two groups of photovoltaic panels 431 are pulled at the same time, so that the photovoltaic panels 431 gradually tilt toward the opposite inner side, thereby effectively guiding the wind in two directions into the generator box 4.

[0096] At the same time, a counterweight is installed at the bottom of the two groups of photovoltaic panels 431 away from the lens plate 432, so that when the traction box 451 drops to the initial position and the traction rope 453 loses the upward pulling force, the photovoltaic panel 431 is rotated in the opposite direction to a horizontal state under the gravity of the counterweight, so that the traction rope 453 is straightened, thereby preventing the photovoltaic panel 431 from being affected by the counterweight and causing excessive rotation.

[0097] Furthermore, protective nets 4315 are fixed to the top and bottom of the top plate 43 , and the protective nets 4315 are attached to the surface of the photovoltaic panel 431 .

[0098] More specifically, the protective net 4315 is an elastic net installed on the top and bottom of the trough body connected to the top plate 43 by the photovoltaic panel 431. When the photovoltaic panel 431 rotates and tilts, the protective net 4315 unfolds and covers the unfolded trough body to prevent sand and gravel from entering the generator box 4.

[0099] Furthermore, an adjusting screw 4314 is rotatably connected in the adjusting slot 4311 , and the adjusting screw 4314 is threadedly connected in the moving block 4312 .

[0100] More specifically, by rotating the adjusting screw 4314 in the forward and reverse directions, the position of the moving block 4312 in the adjusting slot 4311 can be adjusted, thereby ensuring the consistency of the tilt angle of the photovoltaic panel 431 when the traction rope 453 of different lengths is replaced and the height displacement of the traction box 451 changes.

[0101] Example 3

[0102] See also Figure 14-15 As shown, the thermoelectric coupling photovoltaic energy storage device proposed in this embodiment, based on the first and second embodiments, also includes that the auxiliary component 5 includes a support rod 51 fixed to the bottom of the lens plate 432, and a rotating mechanism 53 is installed on the support rod 51.

[0103] The rotating mechanism 53 includes a bevel gear 531 rotatably connected to the bottom end of the support rod 51, a special-shaped rod 532 is fixed at the bottom of the bevel gear 531, a sleeve 533 is movably sleeved on the side of the special-shaped rod 532, and a toothless gear 534 is fixed at the bottom end of the sleeve 533.

[0104] A tooth profile 416 is provided on the inner side of the moving frame 414 , and the toothless gear 534 is engaged with the tooth profile 416 .

[0105] More specifically, the support rod 51 is cross-shaped, and the branch at the top of the support rod 51 is fixed to the bottom of the lens plate 432. The bevel gear 1 531 in the rotating mechanism 53 is rotatably connected to the branch at the bottom end of the support rod. When the bevel gear 1 531 rotates, the special-shaped rod 532 is driven to rotate at the same time, so that the sleeve 533 drives the toothless gear 534 to rotate. Under the force of the meshing of the toothless gear 534 and the tooth profile 416, the moving frame 414 is realized to slide in the bar frame 412.

[0106] It should be further explained that the special-shaped rod 532 is a vertical polygonal rod, such as a pentagonal, hexagonal or octagonal rod, and the length and shape of the sleeve 533 are consistent with the side of the polygonal rod, so that when the special-shaped rod 532 rotates, it can stably drive the sleeve 533 to rotate at the same time.

[0107] Furthermore, the auxiliary component 5 also includes two sets of rotating mechanisms 52 installed on the sides of the support rod 51.

[0108] The rotating mechanism 52 includes a second bevel gear 521 rotatably connected to the side of the support rod 51 , a rotating rod 522 is fixed on the second bevel gear 521 , and a fan blade 523 is fixed at one end of the rotating rod 522 .

[0109] More specifically, bevel gear 2 521 is installed on the branches at opposite ends of the support rod 51, and a rotating rod 522 is installed on the bevel gear 2 521. A fan blade 523 is installed at the front end of each rotating rod 522. The fan blade 523 is blown by natural wind, so that the rotating rod 522 drives the bevel gear 2 521 to rotate.

[0110] Furthermore, the bevel gear 1 531 is meshed with the bevel gear 2 521 .

[0111] More specifically, when the bevel gear 2 521 rotates, the meshing force drives the bevel gear 1 531 to rotate, thereby causing the toothless gear 534 to rotate.

[0112] It should be further explained that when the fan blades 523 in two directions are simultaneously driven to rotate by wind energy, the faster rotating fan blade 523 drives the toothless gear 534 to rotate while also driving the fan blade 523 on the other side to rotate at a constant speed.

[0113] The working principle of the thermoelectric coupling photovoltaic energy storage device proposed in this embodiment is as follows: at night, by controlling the operation of the motor 444, its output end drives the driving gear 445 to rotate, so that the lifting rod 443 drives the lens plate 432 and the auxiliary component 5 to rise to the limit, so that the limit plate 434 is located in the notch of the lens plate 432 on the top plate 43, sealing the notch, and at the same time, the connecting block 4313 is pulled by the traction rope 453, so that the two sets of photovoltaic panels 431 are rotated in opposite directions to an inclined state, and the downward side of the photovoltaic panel 431 is aligned with the fan blade 52. 3 is aligned, so that the fan blades 523 are rotated by natural wind, and the toothless gear 534 is rotated by the meshing force of the bevel gear 2 521 and the bevel gear 1 531. The movable frame 414 slides repeatedly in the bar frame 412 by the meshing action of the toothless gear 534 and the tooth profile 416 and the pushing force of the tension spring 422, so that the friction plate 2 415 and the friction plate 1 413 rub and generate heat, which continuously heats the bottom plate 41, so that the organic phase change material maintains a high temperature at night and provides heat energy to the thermoelectric box 2, thereby continuously generating electricity at night.
