Detailed implementation mode

[0018] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] An embodiment of the present invention provides a solar photovoltaic power generation and energy storage device, as Figures 1 - 10 shown, the solar photovoltaic power generation and energy storage device includes: a base box 1, on the top of the base box 1 is provided a liftable electrical box 2; a storage battery 3 and a charge and discharge control box 4 arranged in the electrical box 2, the storage battery 3 is used for storing the electric energy converted from solar energy; an installation box 5 fixed on the top of the electrical box 2, one side of the installation box 5 is hinged with a mounting plate 6, and a solar photovoltaic panel 7 is arranged on the mounting plate 6, which is used for absorbing solar energy and converting it into electric energy; a lifting mechanism arranged on the electrical box 2 and the base box 1; a support mechanism arranged on the installation box 5 for supporting the mounting plate 6; a cleaning mechanism arranged on the installation box 5 for cleaning the solar photovoltaic panel 7; a liquid spraying mechanism arranged on the installation box 5 for spraying a cleaning liquid on the surface of the solar photovoltaic panel 7.

[0020] In this embodiment, the solar photovoltaic panel 7 absorbs solar energy and converts it into electrical energy. The generated electrical energy is stored in the storage battery 3 through the charging controller in the charge and discharge control box 4. The lifting mechanism can adjust the height of the electrical box 2 relative to the base box 1 according to the water level change, preventing the device from being flooded. The support mechanism can support the mounting plate 6 after it is unfolded, ensuring that the solar photovoltaic panel 7 is at a proper working angle. The cleaning mechanism cleans the solar photovoltaic panel 7, and the liquid spraying mechanism sprays cleaning liquid onto the surface of the solar photovoltaic panel 7 to assist in cleaning, maintaining its good working performance; By setting the lifting mechanism, the electrical box 2 can adaptively adjust its height according to the water level change, effectively preventing the device from being flooded and causing short circuits or damage when the water level rises due to extreme weather such as floods and heavy rains. This greatly improves the waterproof ability of the device in harsh environments such as the rainy season and ensures the safe operation of the equipment. The support mechanism ensures that the solar photovoltaic panel 7 can receive solar energy at a proper angle, improving the power generation efficiency. The settings of the cleaning mechanism and the liquid spraying mechanism can timely clean the dust and other debris on the surface of the solar photovoltaic panel 7, maintaining its high-efficiency photoelectric conversion ability and reducing the reduction of power generation efficiency caused by surface dirt. At the same time, it reduces the maintenance costs caused by equipment damage due to water ingress and performance degradation due to dirt, enhancing the stability of energy supply.

[0021] In a further preferred embodiment of the present invention, the lifting mechanism includes: threaded cylinders 8 symmetrically fixed inside the electrical box 2; screw rods 9 symmetrically assembled on the base box 1 through sealed bearings, with their tops threadedly extending into the corresponding threaded cylinders 8; a first transmission rod 10 assembled in the base box 1 through a sealed bearing, and a first bevel gear 11 fixed to the bottom end of the screw rod 9 on the first transmission rod 10, and the corresponding first bevel gears 11 are meshed with each other for transmission.

[0022] In this embodiment, when adjusting the height of the electrical box 2, when the first transmission rod 10 starts to rotate, since the first bevel gear 11 is fixed on the first transmission rod 10 and the bottom end of the screw rod 9 is also fixed with a first bevel gear 11 meshed with it, the rotation of the first transmission rod 10 drives the first bevel gear 11 to rotate, thereby driving the screw rod 9 meshed with it to rotate. The top of the screw rod 9 threadedly extends into the threaded cylinder 8. As the screw rod 9 rotates, the threaded cylinder 8 moves up and down on the screw rod 9. Since the threaded cylinders 8 are symmetrically fixed inside the electrical box 2, the lifting of the electrical box 2 relative to the base box 1 is realized; This lifting mechanism based on the threaded barrel 8, the screw rod 9, the first transmission rod 10 and the first bevel gear 11 can accurately adjust the height of the electric box 2 according to the change of the water level. When the water level rises due to extreme weather such as floods and rainstorms, the electric box 2 can be raised in time to avoid it being submerged in water, which greatly enhances the waterproof performance of the device in bad weather, ensures the safety of important components such as the battery 3 and the charge and discharge control box 4 in the electric box 2, and prevents problems such as short circuit and damage caused by water ingress; The components of the lifting mechanism are assembled through sealed bearings, which effectively prevents impurities such as water and dust from entering the mechanism, reduces the wear of the components, and prolongs the service life of the mechanism. At the same time, the symmetrically arranged threaded barrel 8 and screw 9 make the electric box 2 evenly stressed during the lifting process, ensuring the stability and reliability of the lifting action, and further improving the stability of the entire solar photovoltaic power generation and energy storage device.

[0023] In a further preferred embodiment of the present invention, the supporting mechanism includes: a first toothed plate 12 slidably mounted in the mounting box 5; a slide groove 13 provided on the mounting plate 6; a slider 14 hinged on the first toothed plate 12, one end of the slider 14 extending into the slide groove 13; a mounting frame 15 fixed to one side of the mounting box 5, a first gear 16 rotatably mounted on the mounting frame 15, and the first gear 16 is meshed with the first toothed plate 12.

[0024] In this embodiment, under normal circumstances, the mounting plate 6 and the solar photovoltaic panel 7 are in an unfolded state, at which time the support mechanism has completed the unfolding operation of the mounting plate 6, and the support mechanism provides stable support for the mounting plate 6, ensuring that the solar photovoltaic panel 7 receives solar energy at an optimal angle; When the water level rises, in order to reduce the damage rate of the solar photovoltaic panel 7, the mounting plate 6 and the solar photovoltaic panel 7 will be folded up. The first gear 16 is rotated to drive the first toothed plate 12 to slide in the opposite direction, and the slider 14 moves in the slide groove 13, pulling the mounting plate 6 to rotate around the hinge point, so that the mounting plate 6 and the solar photovoltaic panel 7 are folded and retracted; When the water level drops, the rotation of the first gear 16 drives the first slotted plate 12 to slide in the installation box 5. The slider 14 hinged on the first slotted plate 12 moves with the first slotted plate 12, and at the same time, one end of the slider 14 slides in the slide groove 13 of the installation plate 6, pushing the installation plate 6 to rotate around the hinge point between the installation plate 6 and the installation box 5 until the installation plate 6 is unfolded to a suitable angle, and the support mechanism provides support for the installation plate 6 again, so that the solar photovoltaic panel 7 returns to a normal working state and continues to efficiently receive solar energy and convert it into electrical energy; Through the ingenious cooperation of the first gear 16, the first grooved plate 12, the slider 14 and the chute 13, the support mechanism can flexibly fold and retract the mounting plate 6 and the solar photovoltaic panel 7 when the water level rises and re-expand them after the water level drops. This design greatly improves the adaptability of the device to complex environments, effectively reduces the damage rate of the device in the scenario of water level change, and ensures the stable operation of the device; Whether in the normal working state or in the process of dealing with water level changes, the support mechanism can accurately control the angle of the mounting plate 6. In the normal state, the solar photovoltaic panel 7 can be quickly adjusted to the best angle for receiving solar energy, improving the adaptability to different lighting conditions and enhancing the power generation efficiency; after the water level changes, it can quickly return to the best working angle, continuously ensuring high-efficiency power generation and reducing power generation interruption and efficiency reduction caused by environmental changes.

[0025] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a second rotating rod 36 assembled on the mounting box 5 through a sealed bearing, with a second spline rod 37 fixed to the top of the second rotating rod 36; a spline sleeve plate 38 sleeved on the second spline rod 37 and with adjustable height; a bracket 39 fixed to the spline sleeve plate 38, with a cleaning roller 40 rotatably installed on the bracket 39 for cleaning the solar photovoltaic panel 7; a wind wheel 53 fixed to the top of the second spline rod 37; a toothed disc 41 assembled on the mounting box 5; and a fifth bevel gear 42 fixed to the shaft of the cleaning roller 40, which can be engaged and disengaged with the toothed disc 41.

[0026] In this embodiment, since the wind wheel 53 is fixed to the top of the second spline rod 37, the rotation of the wind wheel 53 drives the second spline rod 37 to rotate together. The surface of the second spline rod 37 is provided with a raised part, and the spline sleeve plate 38 is provided with a corresponding groove inside. When the cleaning is started, the spline sleeve plate 38 is adjusted to descend, and its groove fits with the raised part of the second spline rod 37, so that the rotation of the second spline rod 37 can drive the spline sleeve plate 38 to move synchronously, and then drive the bracket 39 fixed to the spline sleeve plate 38 to move. The cleaning roller 40 rotatably installed on the bracket 39 approaches the solar photovoltaic panel 7 accordingly. During the approach of the cleaning roller 40, the fifth bevel gear 42 fixed to the shaft of the cleaning roller 40 gradually meshes with the toothed disc 41 assembled on the mounting box 5. The meshing of the toothed disc 41 and the fifth bevel gear 42 causes the cleaning roller 40 to start rotating while approaching the solar photovoltaic panel 7 along with the bracket 39, thereby cleaning the solar photovoltaic panel 7. After the cleaning is completed, the spline sleeve plate 38 is adjusted to rise. At this time, the groove inside the spline sleeve plate 38 is separated from the raised part of the second spline rod 37, the bracket 39 and the cleaning roller 40 move away from the solar photovoltaic panel 7, the fifth bevel gear 42 is separated from the toothed disc 41, and the cleaning roller 40 stops rotating; The cleaning mechanism uses the wind wheel 53 to utilize natural wind power as the power source, without consuming additional electrical energy or other energy sources, greatly reducing the operating cost of the device. The wind drives the wind wheel 53 to rotate, enabling the cleaning work to be started in a timely manner when there is wind, efficiently removing dust, debris, etc. on the surface of the solar photovoltaic panel 7, effectively maintaining the good lighting performance of the solar photovoltaic panel 7, thereby improving the efficiency of converting solar energy into electrical energy, and ensuring the continuous and stable high-efficiency operation of the power generation device.

[0027] In a further preferred embodiment of the present invention, a guide shell 46 is fixedly installed on the top of the base box 1, a guide block 47 is slidably installed in the guide shell 46, and one end of the guide block 47 is fixedly connected to the outer wall of the electrical box 2.

[0028] In this embodiment, the guide block 47 fixedly connected to the outer wall of the electrical box 2 slides in the guide shell 46. Since one end of the guide block 47 is fixed to the electrical box 2 and the other end is in the guide shell 46, the lifting movement of the electrical box 2 drives the guide block 47 to slide up and down along the internal track of the guide shell 46, thereby providing precise guidance for the lifting of the electrical box 2.

[0029] In a further preferred embodiment of the present invention, an electric telescopic rod 43 is fixedly installed in the installation box 5, a top block 44 is fixedly installed on the output rod of the electric telescopic rod 43 for jacking up the spline sleeve plate 38, and a ball 45 is inlaid on the top block 44.

[0030] In this embodiment, when it is necessary to start the cleaning roller 40 to clean the solar photovoltaic panel 7, the electric telescopic rod 43 fixedly installed in the installation box 5 starts to work. The electric telescopic rod 43 retracts, the output rod of the electric telescopic rod 43 retracts, the top block 44 descends, and the spline sleeve plate 38 descends under the action of its own gravity. After the cleaning is completed, the output rod of the electric telescopic rod 43 rises. As the spline sleeve plate 38 rises, the bracket 39 fixed on the spline sleeve plate 38 and the cleaning roller 40 on the bracket 39 also rise accordingly, so that the cleaning roller 40 is away from the solar photovoltaic panel 7; The electric telescopic rod 43 can accurately control the rising and falling heights of the top block 44, thereby accurately controlling the positions of the spline sleeve plate 38 and the cleaning roller 40. This enables the cleaning work to be started and stopped flexibly according to actual needs.

[0031] In a further preferred embodiment of the present invention, support legs 60 are symmetrically fixed at the bottom of the base box 1, a box door is assembled on the electrical box 2 through a hinge, and an air inlet grille is provided on the box door.

[0032] In this embodiment, the support legs 60 symmetrically fixed to the bottom of the base box 1 are in direct contact with the ground when the device is installed, providing stable support for the entire solar photovoltaic power generation and energy storage device. The box door of the electrical box 2 assembled through hinges can rotate around the hinge axis, facilitating opening and closing. When maintenance, repair, or replacement of equipment such as the battery 3 and charge and discharge control box 4 inside the electrical box 2 is required, the box door can be opened. The air inlet grille provided on the box door allows external air to enter the electrical box 2 during the operation of the device, realizing air circulation.

[0033] In a further preferred embodiment of the present invention, a gas guide shell 54 is provided inside the installation box 5. The air inlet end of the gas guide shell 54 is connected to the electrical box 2 through an air extraction pipe 58, and the air outlet end of the gas guide shell 54 is fixedly connected to an exhaust pipe 59 for exhaust heat dissipation.

[0034] In this embodiment, during the operation of the solar photovoltaic power generation and energy storage device, equipment such as the battery 3 and charge and discharge control box 4 inside the electrical box 2 generate heat, causing the air temperature inside the electrical box 2 to rise. At this time, the gas guide shell 54 inside the installation box 5 starts to function. The relatively hot air inside the electrical box 2 is sucked into the gas guide shell 54 through the air extraction pipe 58. The gas guide shell 54 guides the inhaled hot air to the air outlet end, and finally the hot air is discharged to the outside of the device by the exhaust pipe 59 fixedly connected to the air outlet end of the gas guide shell 54, thereby realizing heat dissipation inside the electrical box 2.

[0035] In a further preferred embodiment of the present invention, a through opening is provided on the installation box 5, which is adapted to the first toothed groove plate 12, and a limiting block is fixed to one end of the first toothed groove plate 12.

[0036] In this embodiment, when the first gear 16 on the mounting frame 15 is rotated to adjust the angle of the mounting plate 6, the first toothed groove plate 12 engaged with the first gear 16 slides inside the installation box 5. Since a through opening adapted to the first toothed groove plate 12 is provided on the installation box 5, the first toothed groove plate 12 can slide smoothly through the through opening. During the sliding process, the limiting block fixed to one end of the first toothed groove plate 12 plays a limiting role. When the first toothed groove plate 12 slides to a certain position, the limiting block will abut against the inner wall of the installation box 5 to prevent the first toothed groove plate 12 from sliding excessively and detaching from the installation box 5 or the first gear 16.

[0037] In a further preferred embodiment of the present invention, a maintenance door is assembled on the installation box 5 through hinges, and a rotatable door lock is provided on the maintenance door.

[0038] In this embodiment, when it is necessary to inspect, maintain or troubleshoot the components inside the installation box 5, such as the support mechanism, the cleaning mechanism, etc., the operator first unlocks the door lock on the inspection door by twisting the twistable door lock on the inspection door. Since the inspection door is assembled on the installation box 5 by hinges, after the door lock is opened, the inspection door can be rotated around the hinge axis to open the inspection door, so that the relevant components inside the installation box 5 can be easily accessed. After the inspection work is completed, the inspection door is closed, and the door lock is twisted again so that the door lock re-locks the inspection door to ensure the sealing of the installation box 5.

[0039] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a buoyancy drive mechanism is provided on the base box 1 and the first transmission rod 10, and the buoyancy drive mechanism includes: a mounting shell 17 fixed on the base box 1, and a second toothed plate 18 is slidably mounted on the mounting shell 17; a connecting frame 19 fixed on the bottom end of the second toothed plate 18, and a floating plate 20 is fixed on the connecting frame 19, and a counterweight sleeve 21 is fixed on the floating plate 20; a first rotating rod 22 rotatably mounted in the mounting shell 17 through a bearing, a second gear 23 and a third gear 24 are fixed on the first rotating rod 22, and the second gear 23 is meshed with the second toothed plate 18; a fourth gear 25 rotatably mounted in the mounting shell 17, and the fourth gear 25 is meshed with the third gear 24; a fifth gear 26 fixed on the first transmission rod 10, and the fifth gear 26 is meshed with the fourth gear 25.

[0040] In this embodiment, when the water level changes, the floating plate 20 moves up and down under the buoyancy of the water. The floating plate 20 is connected to the second toothed plate 18 through the connecting frame 19, so the movement of the floating plate 20 drives the second toothed plate 18 to slide on the mounting shell 17. The second toothed plate 18 is meshed with the second gear 23 in the mounting shell 17, and its sliding drives the second gear 23 to rotate. The second gear 23 is fixed on the first rotating rod 22, driving the first rotating rod 22 to rotate synchronously, and the third gear 24 on the first rotating rod 22 rotates accordingly. The third gear 24 is meshed with the fourth gear 25, driving the fourth gear 25 to rotate, and the fourth gear 25 is meshed with the fifth gear 26 fixed on the first transmission rod 10, and finally drives the first transmission rod 10 to rotate. Since the first transmission rod 10 is connected to the screw rod 9 through the first bevel gear 11, the rotation of the first transmission rod 10 realizes the rotation of the screw rod 9, and then drives the threaded cylinder 8 and the electric box 2 connected thereto to rise and fall to adapt to the water level change. The buoyancy drive mechanism can automatically adjust the height of the electric box 2 according to the rise and fall of the water level without manual intervention. When the water level rises rapidly due to extreme weather such as floods and rainstorms, the floating plate 20 can timely sense the water level changes and quickly raise the height of the electric box 2 through a series of gear transmissions to prevent it from being submerged; when the water level drops, the height of the electric box 2 can also be automatically lowered to a suitable position, which greatly improves the timeliness and accuracy of the device in responding to water level changes and ensures the stable operation of the device in complex hydrological environments. The mechanism uses the buoyancy of water as a driving force, does not require additional consumption of electricity or other energy, and is energy-saving and environmentally friendly. At the same time, the gear transmission system of the entire buoyancy drive mechanism is tightly matched and operates smoothly. Compared with other driving methods, it can provide stable power for the lifting of the electric box 2, reduce the shaking or jamming of the electric box 2 during the lifting process caused by unstable power, enhance the reliability and stability of the device, and extend the service life of the device.

[0041] In another embodiment of the present invention, a transmission mechanism is provided on the mounting shell 17 and the mounting box 5 for driving the first gear 16 to rotate, and the transmission mechanism includes: a spline cylinder 27 assembled in the mounting shell 17 through a bearing; a mounting seat 29 fixed on one side of the mounting box 5, a first spline rod 30 is assembled on the mounting seat 29 through a bearing, and the bottom end of the first spline rod 30 extends into the spline cylinder 27; second bevel teeth 28 respectively fixed on the spline cylinder 27 and the first rotating rod 22, and the two second bevel teeth 28 are meshed with each other; a second transmission rod 31 assembled on the mounting box 5 through a bearing, and a third bevel tooth 32 and a fourth bevel tooth 35 are respectively fixed on the top end of the second transmission rod 31 and the shaft of the first gear 16, and the third bevel tooth 32 is meshed with the fourth bevel tooth 35; pulleys 33 respectively fixed on the second transmission rod 31 and the first spline rod 30, and the two pulleys 33 are sleeved with the same transmission belt 34.

[0042] In this embodiment, in the case of water level change, the floating plate 20 first senses the water level fluctuation and generates a corresponding displacement. Since the floating plate 20 is connected to the connecting frame 19, the second toothed groove plate 18 is driven to slide on the mounting shell 17. The sliding of the second toothed groove plate 18 drives the second gear 23 meshing with it to rotate. The second gear 23 is fixed on the first rotating rod 22, so the first rotating rod 22 starts to rotate. As the first rotating rod 22 rotates, the second bevel gear 28 fixed on it rotates together. Through another meshing second bevel gear 28, the rotation is transmitted to the spline cylinder 27, causing the spline cylinder 27 to start rotating. When the spline cylinder 27 rotates, since the bottom end of the first spline rod 30 extends into the spline cylinder 27, the first spline rod 30 rotates accordingly. The pulley 33 fixed on the first spline rod 30 is connected to the pulley 33 on the second transmission rod 31 through a transmission belt 34. The rotation of the first spline rod 30 drives the second transmission rod 31 to rotate by means of the pulley 33 and the transmission belt 34. The third bevel gear 32 fixed at the top end of the second transmission rod 31 meshes with the fourth bevel gear 35. The fourth bevel gear 35 is fixed on the shaft of the first gear 16, thereby driving the first gear 16 to rotate, and finally realizing the angle adjustment of the unfolding or folding of the mounting plate 6. The transmission mechanism innovatively constructs a close connection between the water level change and the angle adjustment of the mounting plate 6. When the water level rises or falls, the movement of the floating plate 20 not only triggers the automatic lifting of the electric box 2 but also synchronously causes the first gear 16 to rotate, thereby precisely adjusting the angle of the mounting plate 6. This means that in different water level environments, the solar photovoltaic panel 7 can quickly and automatically adjust to the optimal angle for receiving solar energy, significantly improving the comprehensive adaptability of the device to complex environments and effectively ensuring the efficient and stable operation of solar power generation.

[0043] In another embodiment of the present invention, a liquid spraying mechanism is provided on the mounting box 5 for spraying a cleaning liquid onto the surface of the solar photovoltaic panel 7. The liquid spraying mechanism includes: a liquid storage tank 48 provided in the mounting box 5, and a submersible pump 49 is provided in the liquid storage tank 48; a liquid outlet pipe 50 fixedly connected to the liquid outlet end of the submersible pump 49, and the liquid outlet end of the liquid outlet pipe 50 extends above the solar photovoltaic panel 7; a liquid spraying pipe 51 fixedly connected to the liquid outlet end of the liquid outlet pipe 50, and a plurality of nozzles are provided on the liquid spraying pipe 51, and a constant temperature heating rod 52 for heating the cleaning liquid is provided in the liquid storage tank 48.

[0044] In this embodiment, when it is necessary to clean the solar photovoltaic panel 7, the submersible pump 49 installed in the liquid storage tank 48 is started. The submersible pump 49 pumps out the cleaning liquid in the liquid storage tank 48 and conveys it through the liquid outlet pipe 50 fixedly connected to its liquid outlet end. The liquid outlet end of the liquid outlet pipe 50 extends above the solar photovoltaic panel 7, and the liquid spraying pipe 51 fixedly connected to the liquid outlet end of the liquid outlet pipe 50 starts to work. Multiple nozzles provided on the liquid spraying pipe 51 evenly spray the cleaning liquid on the surface of the solar photovoltaic panel 7 to achieve the cleaning of the solar photovoltaic panel 7. At the same time, if the ambient temperature is relatively low, the constant temperature heating rod 52 in the liquid storage tank 48 will be started to heat the cleaning liquid to ensure that the cleaning liquid is sprayed at an appropriate temperature and improve the cleaning effect; The liquid spraying mechanism can accurately spray the cleaning liquid on the surface of the solar photovoltaic panel 7. The setting of multiple nozzles ensures the comprehensiveness of the coverage of the cleaning liquid, can effectively remove impurities such as dust and stains on the surface of the solar photovoltaic panel 7, restore its good light collection performance, thereby improving the efficiency of converting solar energy into electrical energy, and ensuring the stable and efficient operation of the power generation device.

[0045] In another embodiment of the present invention, a third rotating rod 55 is assembled on the air guide shell 54 through a bearing, and a fan blade 57 is fixed on the third rotating rod 55; a sixth bevel gear 56 is fixedly installed on the second rotating rod 36 and the third rotating rod 55, and the two sixth bevel gears 56 are meshed with each other.

[0046] In this embodiment, when the wind wheel 53 rotates under the action of wind force, the wind wheel 53 fixed at the top of the second rotating rod 36 drives the second rotating rod 36 to rotate together. Since the sixth bevel gears 56 which are fixedly installed on the second rotating rod 36 and the third rotating rod 55 respectively are meshed with each other, the rotation of the second rotating rod 36 is transmitted to the third rotating rod 55 through the meshing of the sixth bevel gears 56, so that the third rotating rod 55 rotates around the bearing on the air guide shell 54. When the third rotating rod 55 rotates, the fan blade 57 fixed on it rotates accordingly. The rotating fan blade 57 forms an air flow in the air guide shell 54, accelerating the hot air in the electric box 2 to enter the air guide shell 54 through the air extraction pipe 58 and being discharged through the exhaust pipe 59, enhancing the heat dissipation effect. By driving the fan blade 57 to operate through the rotation of the wind wheel 53, the air flow in the air guide shell 54 is actively enhanced. Compared with the heat dissipation method that only relies on natural convection, the speed of discharging heat in the electric box 2 is greatly increased, and the temperature in the electric box 2 is more effectively reduced. This helps to prevent equipment such as the storage battery 3 and the charge and discharge control box 4 from deteriorating or being damaged due to overheating, ensures the stable operation of the power generation device, extends the service life of the equipment, and improves the power generation efficiency. This structure ingeniously utilizes the existing power of the wind driving the wind wheel 53 to rotate, and realizes the rotation of the fan blades 57 through gear transmission, without the need for additional energy input. Without increasing energy consumption, the heat dissipation system is optimized, reflecting the collaborative work among the structures inside the device. It not only makes full use of natural energy, but also improves the performance of the overall device, enhancing the adaptability and reliability of the device under different environmental conditions.

[0047] In summary, compared with the related technologies, the solar energy is absorbed by the solar photovoltaic panel 7 and converted into electrical energy and stored in the storage battery 3; the lifting mechanism and the buoyancy driving mechanism automatically adjust the height of the electrical box 2 to avoid being flooded; the supporting mechanism adjusts the angle of the mounting plate 6 to ensure that the photovoltaic panel receives solar energy at the best angle; the cleaning mechanism and the liquid spraying mechanism clean the surface of the photovoltaic panel to maintain the photoelectric conversion ability; the air guide shell 54 and related structures enhance heat dissipation, and this device achieves the purposes of efficient and stable power generation, adapting to complex environments, and reducing maintenance costs.
