Description

Technical Field

[0001] This invention relates to the field of energy storage and power generation technology, specifically to a micro off-grid energy storage solar power generation system with protective functions. Background Technology

[0002] A microgrid is a small-scale power system that organically combines distributed power sources, energy storage devices, loads, and monitoring and protection devices. It can achieve self-control, protection, and management. As an important component of a microgrid, micro-off-grid energy storage solar power generation system can not only supply power to local loads but also interact with the main grid when necessary, improving the stability and reliability of the power system. Micro-off-grid energy storage solar power generation system can be applied to medium and large-scale outdoor power demand scenarios such as power supply for residential areas without electricity, power supply for communication and broadcasting base stations, power supply for automated control equipment, power supply for fire emergency, and power supply for centralized sewage treatment in new rural areas, and has good application prospects.

[0003] However, existing solutions still have the following problems during use: When the micro-off-grid solar power storage system operates outdoors, the solar photovoltaic panels convert solar energy into direct current, which is then used to charge the energy storage battery pack via a charge / discharge controller. During the continuous charging process, the temperature inside the battery compartment gradually increases. Current methods involve installing ventilation holes and cooling fans inside the battery compartment to dissipate the generated heat and prevent battery overheating and damage. However, the cooling fans are driven by motors, which consume the stored energy of the battery and generate heat, resulting in poor overheating mitigation. When outdoor natural wind energy is abundant... When the wind direction is unpredictable, it is necessary to adjust the wind-guiding components according to the wind direction changes, control the opening and closing direction and angle of the vents, and keep them aligned with the wind direction to maximize the introduction of natural wind. This ensures that natural wind energy can be effectively collected and guided. At the same time, on rainy days, the state of the rainproof components can be adjusted in time to deal with the oblique rain caused by the wind force. This can prevent rainwater from entering and affecting the safety of energy storage power generation operations, and can also continuously dissipate heat to avoid the heat from not being easily dissipated due to the weather, thus affecting the efficiency of energy storage power generation.

[0004] Therefore, we propose a micro-off-grid energy storage solar power generation system with protective functions to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a micro off-grid energy storage solar power generation system with protective functions to solve the problems mentioned in the background art. Currently available micro off-grid energy storage solar power generation systems with protective functions have poor effects on mitigating battery overheating during use. When there is sufficient outdoor natural wind energy, properly guiding the natural wind for heat dissipation can reduce energy consumption. However, it is inconvenient to adjust the wind-guiding components according to the wind direction, resulting in low utilization of natural wind energy. At the same time, on rainy days, the oblique impact of rain caused by wind force can affect the safety of energy storage power generation operations and also make it difficult for heat to dissipate, thus affecting the energy storage power generation problem.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a micro off-grid energy storage solar power generation system with protective functions, comprising a housing, a photovoltaic panel mounted on the top of the housing, a mounting frame fixed inside the housing, an energy storage battery and an integrated inverter / controller mounted on the mounting frame, a motor mounted on the inner bottom of the housing, a cooling fan connected to the output end of the motor, and heat dissipation holes arranged in a crisscross pattern on the mounting frame. Air inlets and outlets are symmetrically opened on the bottom and top of the left and right sides of the housing, respectively.

[0007] It also includes: a wind speed measuring instrument and a rain sensor are installed on the side of the housing, and air guide components are provided on the outside of the air inlets on the left and right sides. The air guide components are symmetrically installed on the left and right sides of the housing. The air guide components guide natural wind to dissipate heat from the energy storage battery, thereby reducing energy consumption and power generation loss.

[0008] The protective components are located on the left and right sides of the housing. These components block rainwater to protect the energy storage battery while maintaining good heat dissipation and improving energy storage efficiency.

[0009] Preferably, the air guiding assembly includes air guiding boxes symmetrically installed on the left and right sides of the housing. A sleeve is fixed in the middle of the top surface of the air guiding box. A sliding rod is slidably connected through the top of the sleeve. The sliding rod is made of magnetic material, and a first electromagnet is installed on the inner wall of the sleeve.

[0010] Preferably, a slide block is installed on the top of the slide rod, a column is slidably connected to the top of the slide block, the bottom outer side of the column is engaged and slidably connected to the inner wall of the slide block, the column is made of magnetic material, and a second electromagnet is installed on the inner wall of the slide block.

[0011] Preferably, a wind cap is fixed to the top of the column. The wind cap is a hemispherical hollow structure. When the wind encounters wind, the wind cap is blown vertically and slides. A wind vane is fixed to the top of the wind cap.

[0012] Preferably, the bottom of the sleeve is integrally connected to a shaft, the shaft is connected to the top inner side of the air guide box through a bearing, and a toothed plate is fixed at the bottom of the shaft. The toothed plate is configured as a fan-shaped structure. After the toothed plate rotates, it meshes with a pinion. The pinion is distributed at equal angles on the top inner side of the air guide box.

[0013] Preferably, the pinion is fixedly connected to the shaft of the flap, the flap is rotatably connected to the air outlet, the air outlet is opened on the three outer sides of the air guide box, and the flap is guided by the air guide structure of the toothed plate and the pinion.

[0014] Preferably, the protective assembly includes a truss connected to the outside of the column by a bearing. The truss is configured as an inverted "U" shape. The bottom of the truss is slidably connected to the middle of the top surface of the piston plate. The piston plate is slidably connected to the top of the oil tank. The oil tank is symmetrically fixed to the top of the air guide box.

[0015] Preferably, the bottom of the truss is made of magnetic material, a third electromagnet is installed on the inner wall of the piston plate, and the piston plate moves up and down in the oil tank through the truss.

[0016] Preferably, the oil tanks on the left and right sides are connected to the first fixed cylinder and the second fixed cylinder respectively through connecting pipes. The first fixed cylinder is fixed to the top of the air guide box. The position of the first fixed cylinder corresponds one-to-one with the position of the air outlet. The outlet of the first fixed cylinder is fixedly connected to the first rain shield through a sliding connection of the first push plate. The first rain shield is hinged at an equal angle to the top of the air guide box.

[0017] Preferably, the second fixing cylinder is installed outside the left and right air outlets. The outlet of the second fixing cylinder is fixedly connected to the second rain shield via a slidingly connected second push plate. The second rain shield is hinged to the top of the inner side of the air outlet and blocks rainwater at the air outlet.

[0018] Compared with existing technologies, the beneficial effects of the micro-off-grid energy storage solar power generation system with protective functions in this invention are: during use, it can reduce energy consumption and heat by maximizing the utilization of natural wind, thereby improving energy storage and power generation efficiency; at the same time, it provides protection during rain, preventing water ingress without affecting heat dissipation, thus maintaining the normal operation of the energy storage battery. The specific details are as follows:

[0019] 1. By setting up the air guide component, when there is sufficient natural wind energy, the wind vane guides the column to drive the slide to rotate. The slide drives the sleeve to rotate through the slide rod. The sleeve drives the shaft to rotate, and the toothed plate rotates accordingly. After the toothed plate rotates, the corresponding small gear meshes, causing the flap in the corresponding air outlet to rotate. This allows the flap to always be aligned with the wind direction according to changes in wind direction, so that the air outlet can introduce natural wind to the maximum extent and enter the shell to dissipate heat from the energy storage battery. The speed of the cooling fan should be automatically adjusted according to the amount of natural wind energy to reduce energy consumption and cooperate with the natural wind for heat dissipation, which is more conducive to the energy storage and power generation of the energy storage battery.

[0020] 2. Through the designed protective components, when it rains and is windy, the rain sensor detects rain, the first electromagnet is energized, and the sleeve and slide rod are attracted and fixed. The second electromagnet is de-energized. When the shaft is slid again by the wind cap, the shaft moves on the slide block. The third electromagnet is energized, and when the shaft slides, the truss drives the piston plate to slide synchronously in the oil tank. The first push plate on the first and second fixed cylinders drives the first rain shield to rotate, and the second push plate drives the second rain shield to rotate synchronously. When it rains and the wind picks up, the rain blows obliquely. The first and second rain shields can adjust the blocking angle according to the change in the angle of the rain falling due to the wind force, so that the rainwater is blocked outside the shell, and the wind can circulate freely for heat dissipation. This can protect the energy storage battery from rain without affecting heat dissipation, thus ensuring that the energy storage battery can be in good working condition in both sunny and rainy weather, thereby improving the efficiency of energy storage power generation.

Detailed Implementation

[0033] 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.

[0034] Please see Figure 1 - Figure 11 As shown, the present invention provides a technical solution:

[0035] A micro-off-grid energy storage solar power generation system with protective functions includes a housing 1, a photovoltaic panel 2 installed on the top of the housing 1, a mounting frame 3 fixed inside the housing 1, an energy storage battery 4 and an integrated inverter control unit 5 installed on the mounting frame 3, a motor 6 installed on the bottom inner side of the housing 1, a cooling fan 7 connected to the output end of the motor 6, and heat dissipation holes 8 arranged in a crisscross pattern on the mounting frame 3. Air inlets 9 and air outlets 10 are symmetrically opened on the bottom and top of the left and right sides of the housing 1, respectively. It also includes a wind speed measuring instrument 11 and a rain sensor 12 installed on the side of the housing 1.

[0036] During operation, the photovoltaic panel 2 converts solar energy into direct current (DC) through the photoelectric effect, and the electricity is stored in the energy storage battery 4. The energy storage battery 4 stores excess electrical energy generated by the photovoltaic panel 2 to power the load at night or when sunlight is insufficient. The inverter control unit 5 regulates and controls the electrical energy output by the photovoltaic panel 2, realizing the charging and discharging management of the energy storage battery 4, preventing overcharging and over-discharging of the energy storage battery 4, and extending the service life of the energy storage battery 4. At the same time, it converts the DC output of the energy storage battery 4 into AC to meet the power demand of AC loads. The heat dissipation holes 8 on the mounting frame 3 facilitate heat dissipation and avoid heat loss that affects the efficiency of power generation and energy storage. The motor 6 drives the cooling fan 7 to rotate, allowing air to enter. Airflow enters through port 9, carrying the heat generated by the energy storage battery 4 and is then discharged through outlet 10 for heat dissipation. When there is wind in nature, natural wind can be selected for heat dissipation, or the working intensity of the cooling fan 7 can be reduced. The anemometer 11 can detect the wind speed. When the anemometer 11 detects sufficient natural wind, it adjusts the operating status of the cooling fan 7, thereby reducing the energy consumption of the motor 6, slowing down the wind speed of the cooling fan 7, or stopping the cooling fan 7, thus achieving energy-saving heat dissipation. The rain sensor 12 can activate protective components to protect the energy storage battery 4 when it rains, preventing rainwater from affecting the normal operation of energy storage and power generation.

[0037] like Figure 1 - Figure 7 and Figure 9As shown, air guide components 13 are provided on the outside of the left and right air inlets 9. The air guide components 13 are symmetrically installed on the left and right sides of the housing 1. The air guide components 13 guide natural wind to dissipate heat from the energy storage battery 4, reducing energy consumption and power generation loss. A sleeve 132 is fixed in the middle of the top surface of the air guide box 131. A sliding rod 133 is slidably connected through the top of the sleeve 132. The sliding rod 133 is made of magnetic material, and a first electromagnet 134 is installed on the inner wall of the sleeve 132. A slide block 135 is installed on the top of 3. A column 136 is slidably connected to the top of the slide block 135. The bottom outer side of the column 136 is engaged and slidably connected to the inner wall of the slide block 135. The column 136 is made of magnetic material. A second electromagnet 137 is installed on the inner wall of the slide block 135. A wind cap 138 is fixed on the top of the column 136. The wind cap 138 is a hemispherical hollow structure. The wind cap 138 is blown vertically and slides when exposed to wind. A wind vane 139 is fixed on the top of the wind cap 138.

[0038] During use, when there is sufficient natural wind energy, the wind vane 139 is blown towards the windward side. The wind vane 139 can effectively collect and guide natural wind under various wind conditions. After the wind vane 139 rotates, it will drive the slide block 135 to rotate synchronously through the column 136. The slide block 135 drives the sleeve 132 to rotate through the slide rod 133. At this time, the first electromagnet 134 is in a de-energized state, and the second electromagnet 137 is in an energized state. The slide block 135 is attracted and fixed to the column 136. Then, in windy weather without rain, after the wind cap 138 is blown upward, it will synchronously drive the slide rod 133 to slide freely on the slide block 135.

[0039] like Figure 5 - Figure 6 and Figure 10 As shown, the bottom of the sleeve 132 is integrally connected to the shaft 1310. The shaft 1310 is connected to the top inner side of the air guide box 131 through the bearing. The bottom of the shaft 1310 is fixed with a toothed plate 1311. The toothed plate 1311 is set with a fan-shaped structure. After the toothed plate 1311 rotates, it meshes with the pinion 1312. The pinion 1312 is evenly distributed at an angle on the top inner side of the air guide box 131. The pinion 1312 is fixedly connected to the shaft of the flap 1313. The flap 1313 is rotatably connected to the air outlet 1314. The air outlet 1314 is opened on the three outer sides of the air guide box 131. The flap 1313 guides the air through the toothed plate 1311 and the pinion 1312.

[0040] During use, the rotation of the sleeve 132 will synchronously drive the bottom shaft 1310 to rotate. After the shaft 1310 rotates, the toothed plate 1311 will rotate accordingly. The rotation direction of the toothed plate 1311 is consistent with the wind direction. After the toothed plate 1311 rotates, it will mesh with the small gear 1312 at the corresponding position on the air guide box 131, thereby causing the flap 1313 in the corresponding air outlet 1314 to rotate. This allows the direction and angle of the flap 1313 to always be aligned with the wind direction according to changes in wind direction, so that the air outlet 1314 can introduce natural wind to the maximum extent and enter the housing 1 to dissipate heat from the energy storage battery 4. The speed of the cooling fan 7 should be automatically adjusted according to the amount of natural wind energy to reduce energy consumption and complete heat dissipation, which is more conducive to the energy storage and power generation of the energy storage battery 4.

[0041] like Figure 1 - Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, the protective component 14 is disposed on the left and right sides of the housing 1. The protective component 14 blocks rainwater to protect the energy storage battery 4 while maintaining good heat dissipation and improving energy storage efficiency. The protective component 14 includes a truss 141 connected to the outside of the column 136 by a bearing. The truss 141 is configured as an inverted "U" shaped structure. The bottom of the truss 141 is slidably connected to the middle of the top surface of the piston plate 142. The piston plate 142 is slidably connected to the top of the oil tank 143. The oil tank 143 is symmetrically fixed to the top of the air guide box 131. The bottom of the truss 141 is made of magnetic material. A third electromagnet 144 is installed on the inner wall of the piston plate 142. The piston plate 142 moves up and down in the oil tank 143 through the truss 141.

[0042] During use, when there is no rain but it is windy, the column 136 slides, which will synchronously drive the truss 141 to move. The third electromagnet 144 is in a non-energized state. When it rains and is windy, the rain sensor 12 detects rain. At this time, the first electromagnet 134 is energized, the sleeve 132 and the slide rod 133 are attracted and fixed, the second electromagnet 137 is in a non-energized state, and when the shaft 1310 is driven to slide again by the wind cap 138, the shaft 1310 will move on the slide block 135. The third electromagnet 144 is energized, so that when the shaft 1310 slides, the truss 141 will drive the piston plate 142 to slide synchronously in the oil tank 143.

[0043] like Figure 2 - Figure 5 , Figure 7 and Figure 11As shown, the left and right oil tanks 143 are connected to the first fixed cylinder 145 and the second fixed cylinder 148 respectively through connecting pipes. The first fixed cylinder 145 is fixed to the top of the air guide box 131. The position of the first fixed cylinder 145 corresponds one-to-one with the position of the air outlet 1314. The outlet of the first fixed cylinder 145 is fixedly connected to the first rain shield 147 through the sliding connection of the first push plate 146. The first rain shield 147 is hinged at an equal angle to the top of the air guide box 131. The second fixed cylinder 148 is installed on the outside of the left and right air outlets 10. The outlet of the second fixed cylinder 148 is fixedly connected to the second rain shield 1410 through the sliding connection of the second push plate 149. The second rain shield 1410 is hinged to the top of the inner side of the air outlet 10. The second rain shield 1410 blocks the rainwater at the air outlet 10.

[0044] During use, after the piston plate 142 slides, it outputs the oil in the oil tank 143 to the inside of the first fixed cylinder 145 and the second fixed cylinder 148. This causes the first push plate 146 to drive the first rain shield 147 to rotate, and the second push plate 149 to drive the second rain shield 1410 to rotate synchronously. When it rains and the wind picks up, the first rain shield 147 and the second rain shield 1410 can adjust the shielding angle according to the change in the angle of the rain falling due to the wind force. This keeps the rainwater outside the casing 1, while the wind can circulate freely for heat dissipation. This can protect the energy storage battery 4 from rain without affecting heat dissipation, thus ensuring that the energy storage battery 4 can be in good working condition in both sunny and rainy weather, thereby improving the efficiency of energy storage and power generation.

[0045] Working principle: When using this micro off-grid energy storage solar power generation system with protective functions, in windy and rainless weather, the photovoltaic panel 2 converts solar energy into direct current through the photoelectric effect, and the electricity is stored in the energy storage battery 4. The energy storage battery 4 is used to store the excess electrical energy generated by the photovoltaic panel 2 so as to supply power to the load at night or when there is insufficient sunlight. The inverter control unit 5 regulates and controls the electrical energy output by the photovoltaic panel 2, realizes the charging and discharging management of the energy storage battery 4, prevents the energy storage battery 4 from being overcharged and over-discharged, and extends the service life of the energy storage battery 4. At the same time, it converts the direct current output by the energy storage battery 4 into alternating current to meet the power demand of the AC load. The heat dissipation holes 8 on the mounting frame 3 facilitate heat dissipation and avoid heat loss that affects the efficiency of power generation and energy storage. The motor 6 drives the cooling fan 7 to rotate, and the air inlet 9 inputs flowing air. The air carries the heat generated by the energy storage battery 4 and is discharged from the air outlet 10 for heat dissipation.

[0046] Secondly, the anemometer 11 can detect the strength of natural wind. When the anemometer 11 detects sufficient natural wind energy, it adjusts the operating status of the cooling fan 7, thereby reducing the energy consumption of the motor 6, slowing down the wind speed of the cooling fan 7, or stopping the cooling fan 7, thus achieving energy-saving heat dissipation. The wind vane 139 is blown towards the windward side. The wind vane 139 can ensure effective collection and guidance of natural wind under various wind conditions. After the wind vane 139 rotates, it will synchronously drive the slide block 135 to rotate through the column 136. The slide block 135 drives the sleeve 132 to rotate through the slide rod 133. At this time, the first electromagnet 134 is in a de-energized state, and the second electromagnet 137 is in a energized state. The slide block 135 and The column 136 is fixed by adsorption. In windy weather without rain, the wind cap 138 is blown upward and will simultaneously drive the slide rod 133 to slide freely on the slide block 135. After the sleeve 132 rotates, it will simultaneously drive the bottom shaft 1310 to rotate. After the shaft 1310 rotates, the toothed plate 1311 will rotate accordingly. The rotation direction of the toothed plate 1311 is consistent with the wind direction. After the toothed plate 1311 rotates, it will mesh with the small gear 1312 at the corresponding position on the air guide box 131, thereby causing the flap 1313 in the corresponding air outlet 1314 to rotate. This allows the direction and angle of the flap 1313 to always be aligned with the wind direction according to the wind direction changes, so that the air outlet 1314 can introduce natural wind to the maximum extent, which is beneficial to the energy storage and power generation of the energy storage battery 4.

[0047] Furthermore, in windy conditions without rain, when the column 136 slides, it synchronously drives the truss 141 to move, and the third electromagnet 144 is in a de-energized state. In rainy and windy weather, the rain sensor 12 can activate the protective components to protect the energy storage battery 4 when it rains. At this time, the first electromagnet 134 will also be energized, and the sleeve 132 and the slide rod 133 will be attracted and fixed. The second electromagnet 137 is in a de-energized state. When the shaft 1310 is driven to slide again by the wind cap 138, the shaft 1310 will move on the slide block 135. The third electromagnet 144 is energized, so that when the shaft 1310 slides, the truss 141 will drive the piston plate 142 to slide synchronously in the oil tank 143. After the piston plate 142 slides, it will push the oil tank... Oil is output from 143 to the interior of the first fixed cylinder 145 and the second fixed cylinder 148, which causes the first push plate 146 to drive the first rain shield 147 to rotate, and the second push plate 149 to drive the second rain shield 1410 to rotate synchronously. When it rains and the wind picks up, the first rain shield 147 and the second rain shield 1410 can adjust the shielding angle according to the change in the angle of the rain falling due to the wind force, so that the rainwater is blocked outside the shell 1, avoiding rainwater from soaking and affecting the normal operation of energy storage and power generation. The wind can circulate freely for heat dissipation, which can protect the energy storage battery 4 from rain without affecting heat dissipation, thus ensuring that the energy storage battery 4 can be in good working condition in both sunny and rainy days, thereby improving the efficiency of energy storage and power generation.

The top of the slide rod (133) is equipped with a slide block (135), and the top of the slide block (135) is slidably connected to a column (136). The bottom outer side of the column (136) is engaged and slidably connected to the inner wall of the slide block (135). The column (136) is made of magnetic material, and a second electromagnet (137) is installed on the inner wall of the slide block (135). The top of the column (136) is fixed with a wind cap (138), which is a hemispherical hollow structure. The wind cap (138) is blown vertically and slides when exposed to wind. The top of the wind cap (138) is fixed with a wind vane (139). The bottom of the sleeve (132) is integrally connected to a shaft (1310), which is connected to the top of the inner side of the air guide box (131) through a bearing. A toothed plate (1311) is fixed at the bottom of the shaft (1310). The toothed plate (1311) is configured as a fan-shaped structure.
