Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, specifically to an adaptively adjustable solar power supply and energy storage photovoltaic smart box. Background Technology

[0002] Currently, outdoor power distribution equipment, especially photovoltaic energy storage equipment, generally suffers from the problem of balancing heat dissipation and waterproofing. Traditional distribution boxes mostly adopt a fixed heat dissipation hole design, which has a certain heat dissipation capacity, but is prone to water leakage in harsh environments such as heavy rain and water accumulation, leading to damage to internal electronic components. In addition, most existing photovoltaic power generation devices adopt a fixed installation method, which cannot adjust the angle of photovoltaic panels in real time according to the sun's position, resulting in low power generation efficiency. Especially in high-latitude or large temperature difference regions, the internal temperature of the box is difficult to control stably, further affecting the equipment's lifespan and operational reliability. Therefore, there is an urgent need for a new type of photovoltaic energy storage equipment that can intelligently adjust the orientation of photovoltaic panels to improve power generation efficiency and achieve an adaptive balance between heat dissipation and waterproofing. Summary of the Invention

[0003] The purpose of this invention is to provide an adaptively adjustable solar power supply and energy storage photovoltaic smart box to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adaptively adjustable solar power supply and energy storage photovoltaic smart box, comprising a photovoltaic box, a solar power generation module, an energy storage unit, a temperature regulation unit, and a central control unit. The solar power generation module is disposed on the top of the photovoltaic box, the energy storage unit and the temperature regulation unit are disposed inside the photovoltaic box, and the central control unit is electrically connected to the solar power generation module, the energy storage unit and the temperature regulation unit. The solar power generation module includes a base, an adjustment mechanism, and two photovoltaic panels. The adjustment mechanism is mounted on the base, and the two photovoltaic panels are mounted on the adjustment mechanism. During power generation, the adjustment mechanism is controlled by a central control unit. The adjustment mechanism adjusts the orientation and tilt angle of the two photovoltaic panels to ensure that sunlight shines directly on the photovoltaic panels for a long time, thereby improving power generation efficiency. The temperature control unit controls the temperature of the photovoltaic box through heat dissipation and heating to adapt to normal operation in extreme temperature difference environments. The energy storage unit stores the electrical energy generated by the photovoltaic panels and supplies power to the monitoring probe.

[0005] Furthermore, the adjustment mechanism includes a support plate and an adapter frame. The support plate is disposed on the upper surface of the base, and the adapter frame is rotatably connected to the support plate. Two photovoltaic panels are symmetrically mounted on the adapter frame, with the sun-facing sides of the two photovoltaic panels set at an obtuse angle. When both photovoltaic panels are simultaneously exposed to sunlight, the intensity of the light received by the two photovoltaic panels changes as the angle of direct sunlight changes. Therefore, the electrical energy generated by the two photovoltaic panels differs. The central control unit monitors the power generation of the two photovoltaic panels in real time to determine the angle of direct sunlight, so as to adjust the state and position of the support plate and the adapter frame in real time through the adjustment mechanism to achieve the effect of adjusting the angle of the photovoltaic panels.

[0006] Furthermore, the adjustment mechanism includes a first screw, a second screw, and a special gear. The special gear is located below the support plate, passes through the base, and is disposed inside it. The first screw and the second screw are rotatably mounted inside the base, and the first screw and the second screw mesh with the two sides of the special gear, respectively. One end of each of the first screw and the second screw is connected to a servo motor. The two servo motors are connected to the central control unit circuit. The central control unit drives the two servo motors to drive the first screw and the second screw to rotate, respectively. When the first screw and the second screw rotate in the same direction and at the same speed, the special gear translates between the first screw and the second screw. When the first screw and the second screw rotate in opposite directions and at the same speed, the special gear rotates in place between the first screw and the second screw. When the first screw and the second screw rotate in opposite directions and at different speeds, the special gear rotates and moves simultaneously between the first screw and the second screw, thereby achieving control of the compound displacement form of the special gear.

[0007] Furthermore, the adjustment mechanism includes a ramp block, at least one limiting frame, and a traction component. The ramp block is disposed inside the base, and a concave rail is provided on the upper surface of the ramp block. At least one limiting frame is fixedly installed on the side of the adapter frame away from the photovoltaic panel. The traction component passes through the support plate and the special gear. The traction component is installed between the concave rail of the ramp block and the adapter frame. The special gear drives the support plate to move, and the support plate drives the adapter frame to move. When the special gear only rotates, the photovoltaic panel changes its orientation without changing its pitch angle.

[0008] Furthermore, the traction component includes a connector, a number of pins equal to the number of limiting frames, a sliding column, and rollers. The pins are mounted on the connector and slidably disposed in the slot between the limiting frame and the adapter frame. The sliding column passes through the support plate and the special gear, and there is sliding contact between the sliding column and the support plate and the special gear. The connector is rotatably mounted on the top of the sliding column, and the roller is rotatably mounted on the bottom of the sliding column. The roller makes rolling contact with the concave rail. Since the roller is constrained in the concave rail, it rises and falls with the slope when rolling on the ramp. Because the connector and the sliding column are rotatably connected, only axial lifting displacement is transmitted between the connectors, and torsional force cannot be transmitted. Therefore, when the special gear only moves in translation, the sliding column drives the photovoltaic panel to change the pitch angle without changing the orientation. Through the setting of the adjustment mechanism, stepless adjustment of the angle and position of the photovoltaic panel is realized, ensuring that sunlight shines directly on the photovoltaic panel for a long time, thereby improving the power generation efficiency.

[0009] Furthermore, several downward-sloping heat dissipation slots are provided on both sides of the photovoltaic box. Slide rails are provided on the upper and lower sides of the corresponding heat dissipation slots inside the photovoltaic box. A sealing plate is slidably installed between the two slide rails on each side of the photovoltaic box. The sealing plate seals all the heat dissipation slots. When the photovoltaic box is flooded during the flood season, the sealing plate is used to seal the heat dissipation slots to prevent water from seeping into the photovoltaic box and causing damage to electronic components.

[0010] Furthermore, the photovoltaic box has a rotating shaft inside, with a driven gear installed on both sides of the shaft and a driving gear installed in the middle of the shaft. The diameter of the driving gear is smaller than that of the driven gear. Each of the closed panels has a toothed groove at its bottom, and a pair of driven gears are respectively connected to the two closed panels through the toothed groove.

[0011] Furthermore, a cylindrical tube is connected to the bottom of the photovoltaic box, and the cylindrical tube is connected to the outside. A piston is slidably and sealed inside the cylindrical tube, and a rack is provided on the top of the piston. The rack meshes with a drive gear. When water overflows the cylindrical tube, a pressure difference is formed between the inside and outside of the cylindrical tube. The water pressure pushes the piston upward. The piston drives the drive gear to rotate through the rack. The drive gear drives two driven gears to rotate through the shaft. The driven gears drive the sealing plate to slide between the slide rails through the toothed grooves, thereby closing the heat dissipation groove. When the water recedes, the piston returns to its original position under the action of gravity, and the sealing plate reopens the heat dissipation groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves real-time tracking of the sun's position by setting an adjustable-angle photovoltaic panel and a matching adjustment mechanism, ensuring that the photovoltaic panel is always at the optimal angle of light reception, significantly improving the efficiency of solar power generation. The whole machine has adaptive control capabilities and can operate stably under extreme temperature differences and harsh weather conditions, improving the environmental adaptability and reliability of the equipment, and is suitable for a variety of outdoor application scenarios.

[0013] 2. By setting up a heat dissipation structure with a closed grille and a hydraulically triggered sealing mechanism, the heat dissipation groove can be automatically sealed in a water-filled environment to effectively prevent water from entering, while maintaining good heat dissipation when there is no water accumulation, thus solving the technical problem that heat dissipation and waterproofing cannot be achieved at the same time.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example: Figures 1-6As shown, this invention provides a technical solution: an adaptively adjustable solar power supply and energy storage photovoltaic smart box, including a photovoltaic box 1, a solar power generation module, an energy storage unit, a temperature regulation unit, and a central control unit. The solar power generation module is located on the top of the photovoltaic box 1, and the energy storage unit and temperature regulation unit are located inside the photovoltaic box 1. The central control unit is electrically connected to the solar power generation module, the energy storage unit, and the temperature regulation unit. The solar power generation module includes a base 4, an adjustment mechanism, and two photovoltaic panels 10. The adjustment mechanism is located on the base 4, and the two photovoltaic panels 10 are mounted on the adjustment mechanism. During power generation, the central control unit controls the adjustment mechanism. The adjustment mechanism adjusts the orientation and tilt angle of the two photovoltaic panels 10 to ensure that sunlight shines directly on the photovoltaic panels 10 for a long time, thereby improving power generation efficiency. The temperature regulation unit controls the temperature of the photovoltaic box 1 through heat dissipation and heating to adapt to normal operation in extreme temperature difference environments. The energy storage unit stores the electrical energy generated by the photovoltaic panels 10 and supplies power to the monitoring probe.

[0018] The adjustment mechanism includes a support plate 8 and an adapter frame 9. The support plate 8 is located on the upper surface of the base 4, and the adapter frame 9 is rotatably connected to the support plate 8. Two photovoltaic panels 10 are symmetrically mounted on the adapter frame 9, with the sun-facing sides of the two photovoltaic panels 10 set at an obtuse angle. The adjustment mechanism includes a first screw 5, a second screw 6, and a special gear 16. The special gear 16 is located below the support plate 8, passes through the base 4, and is located inside it. The first screw 5 and the second screw 6 are rotatably mounted inside the base 4, and the first screw 5 and the second screw 6 mesh with the two sides of the special gear 16, respectively. One end of each of the first screw 5 and the second screw 6 is connected to a servo motor (not shown in the figure). The two servo motors are connected to the central control unit circuit. When the two photovoltaic panels 10 are simultaneously exposed to sunlight, the intensity of the light received by the two photovoltaic panels 10 changes as the angle of direct sunlight changes. Because the two photovoltaic panels 10 generate different amounts of electricity, the central control unit monitors the power generation of the two photovoltaic panels 10 in real time to determine the direct angle of sunlight. This allows the central control unit to adjust the state and position of the support plate 8 and the adapter frame 9 via an adjustment mechanism, thereby adjusting the angle of the photovoltaic panels 10. The central control unit drives two servo motors to rotate the first screw 5 and the second screw 6 respectively. When the first screw 5 and the second screw 6 rotate in the same direction and at the same speed, the special gear 16 translates between the first screw 5 and the second screw 6. When the first screw 5 and the second screw 6 rotate in opposite directions and at the same speed, the special gear 16 rotates in place between the first screw 5 and the second screw 6. When the first screw 5 and the second screw 6 rotate in opposite directions and at different speeds, the special gear 16 rotates and moves simultaneously between the first screw 5 and the second screw 6, achieving control of the special gear 16 through a composite displacement mechanism.

[0019] The adjustment mechanism includes a ramp block 7, at least one limiting frame 11, and a traction component. The ramp block 7 is disposed inside the base 4, and a recessed rail is provided on the upper surface of the ramp block 7. At least one limiting frame 11 is fixedly installed on the side of the adapter frame 9 away from the photovoltaic panel 10. The traction component passes through the support plate 8 and the special gear 16, and is installed between the recessed rail of the ramp block 7 and the adapter frame 9. The traction component includes a connector 12, a number of pins 13 equal to the number of limiting frames 11, a sliding column 14, and a roller 15. The pins 13 are installed on the connector 12 and are slidably disposed in the slot between the limiting frame 11 and the adapter frame 9. The sliding column 14 passes through the support plate 8 and the special gear 16, and the sliding column 14 is in sliding contact with the support plate 8 and the special gear 16. The connector 12 is rotatably mounted on the top of the sliding column 14, and the roller 15 rotates... The photovoltaic panel 10 is mounted on the bottom of the sliding column 14. The roller 15 rolls in contact with the concave rail. The special gear 16 drives the support plate 8 to move, and the support plate 8 drives the adapter frame 9 to move. When the special gear 16 rotates, the photovoltaic panel 10 changes its orientation but not its pitch angle. Since the roller 15 is constrained in the concave rail, it rises and falls with the slope when rolling on the ramp 7. Since the connector 12 is rotatably connected to the sliding column 14, only axial lifting displacement is transmitted between the connectors 12, and torsional force cannot be transmitted. Therefore, when the special gear 16 moves only in translation, the sliding column 14 drives the photovoltaic panel 10 to change its pitch angle but not its orientation. Through the setting of the adjustment mechanism, the stepless adjustment of the angle and position of the photovoltaic panel 10 is realized, ensuring that sunlight shines directly on the photovoltaic panel 10 for a long time, thereby improving the power generation efficiency.

[0020] The photovoltaic box 1 has several downward-sloping heat dissipation slots 2 on both sides. Inside the photovoltaic box 1, there are sliding rails 3 on the upper and lower sides corresponding to the heat dissipation slots 2. A sealing plate 17 is slidably installed between the two sliding rails 3 on each side of the photovoltaic box 1. The sealing plate 17 seals all the heat dissipation slots 2. A rotating shaft 19 is installed inside the photovoltaic box 1. A driven gear 18 is installed on both sides of the rotating shaft 19. A driving gear 20 is installed in the middle of the rotating shaft 19. The diameter of the driving gear 20 is smaller than the diameter of the driven gear 18. A toothed groove is opened at the bottom of each sealing plate 17. A pair of driven gears 18 are respectively connected to the two sealing plates 17 through the toothed grooves. A cylindrical tube 23 is connected to the bottom of the photovoltaic box 1. The cylindrical tube 23 is connected to the outside. A piston 21 is slidably and sealed in the cylindrical tube 23. A rack 22 is provided on the top of the piston 21. The rack 22 meshes with the driving gear 20.

[0021] During the flood season, when the photovoltaic box 1 is submerged in water, the sealing plate 17 is used to seal the heat dissipation slot 2 to prevent water from seeping into the photovoltaic box 1 and damaging the electronic components. When the water overflows the cylindrical tube 23, a pressure difference is formed between the inside and outside of the cylindrical tube 23. The water pressure pushes the piston 21 upward. The piston 21 drives the drive gear 20 to rotate through the rack 22. The drive gear 20 drives the two driven gears 18 to rotate through the rotating shaft 19. The driven gears 18 drive the sealing plate 17 to slide between the slide rail clips 3 through the toothed groove, thereby sealing the heat dissipation slot 2. When the water recedes, the piston 21 returns to its original position under the action of gravity, and the sealing plate 17 reopens the heat dissipation slot 2.

[0022] The working principle of this invention is as follows: During the power generation process, the central control unit controls the adjustment mechanism. The adjustment mechanism adjusts the orientation and tilt angle of the two photovoltaic panels 10 to ensure that sunlight shines directly on the photovoltaic panels 10 for a long time, thereby improving the power generation efficiency. The temperature control unit controls the temperature of the photovoltaic box 1 through heat dissipation and heating to adapt to normal operation in extreme temperature difference environments. The energy storage unit stores the electrical energy generated by the photovoltaic panels 10 and supplies power to the monitoring probe.

[0023] Two photovoltaic panels 10 are simultaneously exposed to sunlight. When the angle of direct sunlight changes, the intensity of light received by the two photovoltaic panels 10 changes, resulting in different electrical energy outputs. The central control unit monitors the power generation of the two photovoltaic panels 10 in real time to determine the angle of direct sunlight. This allows the central control unit to adjust the state and position of the support plate 8 and the adapter frame 9 in real time via the adjustment mechanism, thereby adjusting the angle of the photovoltaic panels 10. The central control unit drives two servo motors to rotate the first screw 5 and the second screw 6 respectively. When the first screw 5 and the second screw 6 rotate in the same direction and at the same speed, the special gear 16 translates between the first screw 5 and the second screw 6. When the first screw 5 and the second screw 6 rotate in opposite directions and at the same speed, the special gear 16 rotates in place between the first screw 5 and the second screw 6. When the first screw 5 and the second screw 6 rotate in opposite directions and at different speeds, the special gear 16 rotates and moves simultaneously between the first screw 5 and the second screw 6, achieving control of the special gear 16 through a composite displacement mechanism.

[0024] The special gear 16 drives the support plate 8 to move, and the support plate 8 drives the adapter frame 9 to move. When the special gear 16 rotates, the photovoltaic panel 10 changes its orientation but not its pitch angle. Since the roller 15 is constrained in the concave rail, the roller 15 rises and falls with the slope when it rolls on the ramp 7. Since the connector 12 is rotatably connected to the sliding column 14, the connector 12 only transmits axial lifting displacement and cannot transmit torsional force. Therefore, when the special gear 16 moves only in translation, the sliding column 14 drives the photovoltaic panel 10 to change its pitch angle but not its orientation. Through the setting of the adjustment mechanism, the stepless adjustment of the angle and position of the photovoltaic panel 10 is realized, ensuring that sunlight shines directly on the photovoltaic panel 10 for a long time and achieving the purpose of improving power generation efficiency.

[0025] During the flood season, when the photovoltaic box 1 is submerged in water, the sealing plate 17 is used to seal the heat dissipation slot 2 to prevent water from seeping into the photovoltaic box 1 and damaging the electronic components. When the water overflows the cylindrical tube 23, a pressure difference is formed between the inside and outside of the cylindrical tube 23. The water pressure pushes the piston 21 upward. The piston 21 drives the drive gear 20 to rotate through the rack 22. The drive gear 20 drives the two driven gears 18 to rotate through the rotating shaft 19. The driven gears 18 drive the sealing plate 17 to slide between the slide rail clips 3 through the toothed groove, thereby sealing the heat dissipation slot 2. When the water recedes, the piston 21 returns to its original position under the action of gravity, and the sealing plate 17 reopens the heat dissipation slot 2.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
