Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power generation, and in particular to a micro off-grid energy storage solar power generation system with a protection function. Background Art

[0002] A microgrid is a small 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, a micro off-grid energy storage solar power generation system can not only supply power to local loads, but also interact with the large power grid when necessary to improve the stability and reliability of the power system. The micro off-grid energy storage solar power generation system can be used in medium and large outdoor power demand scenarios such as power supply for life in areas without electricity, power supply for communication and broadcasting base stations, power supply for automation control equipment, power supply for fire emergency, and power supply for centralized sewage treatment in new rural areas. It has good prospects for use.

[0003] However, the existing solutions still have the following problems during use: when the micro-off-grid energy storage solar power generation system is working outdoors, the solar photovoltaic panel converts solar energy into direct current, and charges the energy storage battery pack through the charge and discharge controller. During the continuous charging process of the battery pack responsible for energy storage, the temperature inside the battery compartment will gradually increase. The existing method is to set heat dissipation holes and heat dissipation fans in the battery compartment to dissipate the generated heat to prevent the battery from overheating and damage. However, the heat dissipation fan is driven by a motor, which consumes the battery's storage capacity and generates heat at the same time, which makes the battery overheating relief effect poor. When there is sufficient natural wind energy outdoors When the wind is blowing, the energy consumption can be reduced by guiding the natural wind properly for heat dissipation. However, the wind direction of natural wind is changeable, so it is necessary to adaptively adjust the air induction components according to the wind direction change, control the opening and closing direction and angle of the vents, so that they are always aligned with the wind direction, and introduce natural wind to the greatest extent to ensure that natural wind energy can be effectively collected and guided. At the same time, on rainy days, the state of the rain shield components can be adjusted in time according to the slanting rain caused by the wind force, so as to prevent rainwater from entering and affecting the safety of energy storage power generation operations, and to continue to dissipate heat to avoid the influence of weather and the difficulty of heat dissipation, thereby affecting the efficiency of energy storage power generation.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 - Fig.11 As shown, the present invention provides a technical solution: A micro off-grid energy storage solar power generation system with a protective function, comprising a shell 1, a photovoltaic panel 2 is installed on the top of the shell 1, a mounting frame 3 is fixed inside the shell 1, an energy storage battery 4 and an inverter integrated machine 5 are mounted on the mounting frame 3, a motor 6 is installed on the inner bottom of the shell 1, a cooling fan 7 is connected to the output end of the motor 6, cooling holes 8 are crisscrossed and connected 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 shell 1, and further comprising: an anemometer 11 and a rain sensor 12 are installed on the side of the shell 1; During use, 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 electricity generated by the photovoltaic panel 2 so as to power the load at night or when there is insufficient light. The inverter 5 adjusts and controls the electricity output by the photovoltaic panel 2 to achieve charge and discharge management of the energy storage battery 4 group, prevent the energy storage battery 4 from being overcharged and over-discharged, and extend the service life of the energy storage battery 4. At the same time, the direct current output by the energy storage battery 4 group is converted into alternating current to meet the power demand of the alternating current load. The heat dissipation holes 8 on the mounting frame 3 are convenient for heat dissipation to avoid heat loss and affect the efficiency of power generation and energy storage. The heat dissipation fan 7 is driven by the motor 6 to rotate, and the air intake The port 9 inputs flowing air, and the air entrains the heat generated by the energy storage battery 4 and is discharged from the air 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 size of the wind force in nature. When the anemometer 11 detects that the natural wind energy is sufficient, the use status of the cooling fan 7 is adjusted, thereby reducing the energy consumption of the motor 6, and the wind speed of the cooling fan 7 can be slowed down, or the cooling fan 7 can be stopped, thereby saving energy and heat dissipation. The rain sensor 12 can activate the protective component to protect the energy storage battery 4 when it rains, to prevent rainwater from infiltrating and affecting the normal energy storage power generation work.

[0021] like Figure 1 - Figure 7 and Fig. 9 As shown, the outside of the air inlets 9 on the left and right sides are provided with air guide components 13, which are symmetrically installed on the left and right sides of the housing 1. The air guide components 13 guide natural wind to dissipate heat to the energy storage battery 4, thereby reducing energy consumption and power generation losses. A sleeve 132 is fixed to the middle of the top surface of the air guide box 131, and a slide bar 133 is slidably connected through the top of the sleeve 132. The slide bar 133 is set to a magnetic material, and a first electromagnet 134 is installed on the inner wall of the sleeve 132. The slide bar 133 is set to a magnetic material, and a first electromagnet 134 is installed on the inner wall of the sleeve 132. 3 is provided with a slide seat 135 at the top, and a column 136 is slidably connected to the top of the slide seat 135, and the bottom outer side of the column 136 is engaged and slidably engaged with the inner wall of the slide seat 135, and the column 136 is set as a magnetic material, and a second electromagnet 137 is installed on the inner wall of the slide seat 135, and a hood 138 is fixed on the top of the column 136, and the hood 138 is set as a hemispherical hollow structure, and the hood 138 is blown to slide vertically when encountering wind, and a weather vane 139 is fixed on the top of the hood 138; During use, when natural wind energy is sufficient, the wind vane 139 is blown to point to the windward side. The wind vane 139 can ensure that the natural wind can be effectively collected and guided under various wind direction conditions. After the wind vane 139 rotates, it will synchronously drive the slide 135 to rotate synchronously through the column 136. The slide 135 drives the sleeve 132 to rotate through the slide rod 133. At this time, the first electromagnet 134 is in an off-state, and the second electromagnet 137 is in an energized state. The slide 135 is adsorbed and fixed to the column 136. Then, when there is no rain but wind, the wind hood 138 is blown upward, and the slide rod 133 is synchronously driven to slide freely on the slide 135.

[0022] like Figure 5 - Figure 6 and Fig.10 As shown, the bottom of the sleeve 132 is integrally connected with a shaft 1310, and the shaft 1310 passes through the bearing and is connected to the inner top of the air guide box 131, and a tooth plate 1311 is fixed to the bottom of the shaft 1310, and the tooth plate 1311 is set as a fan-shaped structure, and the tooth plate 1311 is meshed with a pinion 1312 after rotation, and the pinion 1312 is distributed at equal angles on the inner side of the top of the air guide box 131, and the pinion 1312 is fixedly connected to the shaft of the flap 1313, and the flap 1313 is rotatably connected to the air supply port 1314, and the air supply port 1314 is opened on the three outer sides of the air guide box 131, and the flap 1313 guides the air through the tooth plate 1311 and the pinion 1312. After the shaft 1310 rotates, the tooth plate 1311 will rotate accordingly. The rotation direction of the tooth plate 1311 is consistent with the wind direction. After the tooth plate 1311 rotates, it will mesh with the small gear 1312 at the corresponding position on the air guide box 131, thereby rotating the flap 1313 in the corresponding air supply port 1314. It is convenient to always align the direction and angle of the flap 1313 with the wind direction according to the change of wind direction, so that the air supply port 1314 can introduce natural wind to the greatest extent, and enter the shell 1 to dissipate heat for the energy storage battery 4. The speed of the cooling fan 7 should be automatically adjusted according to the size of the natural wind energy to reduce energy consumption and complete heat dissipation, which is more conducive to the energy storage and power generation work of the energy storage battery 4.

[0023] like Figure 1 - Figure 5 , Figure 7 , Fig.10 and Fig.11As shown, the protective component 14 is arranged on the left and right sides of the shell 1, and the protective component 14 blocks rainwater to protect the energy storage battery 4 while maintaining a good heat dissipation effect to improve the power storage efficiency. The protective component 14 includes a truss 141 connected to the outside of the column 136 by a bearing, and the truss 141 is arranged as an inverted "U"-shaped structure, and the bottom of the truss 141 penetrates and slides to the middle of the top surface of the piston plate 142, and the piston plate 142 penetrates and slides to the top of the oil tank 143, and the oil tank 143 is symmetrically fixed to the top of the air guide box 131. The bottom of the truss 141 is arranged to be a magnetic material, and a third electromagnet 144 is installed on the inner wall of the piston plate 142, and the piston plate 142 moves up and down in the oil tank 143 through the truss 141; During use, when there is no rain but wind, when the column 136 slides, it will synchronously drive the truss 141 to move with it, and the third electromagnet 144 is in an off-state. When it rains and is windy, the rain sensor 12 detects rain, and at this time the first electromagnet 134 is energized, the sleeve 132 and the slide rod 133 are adsorbed and fixed, and the second electromagnet 137 is in an off-state. When the shaft rod 1310 is driven to slide by the wind cap 138 again, the shaft rod 1310 will move on the slide seat 135, and the third electromagnet 144 will be energized, so that when the shaft rod 1310 slides, the truss 141 will drive the piston plate 142 to slide synchronously in the oil tank 143.

[0024] like Figure 2 - Figure 5 , Figure 7 and Fig.11 As shown, the oil tanks 143 on the left and right sides are respectively connected with the first fixed cylinder 145 and the second fixed cylinder 148 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 to the position of the air supply port 1314, the outlet of the first fixed cylinder 145 is fixedly connected to the first rain shield 147 through a slidingly connected first push plate 146, the first rain shield 147 is hinged to the top of the air guide box 131 at an equal angle, the second fixed cylinder 148 is installed on the outside of the air outlet 10 on the left and right sides, the outlet of the second fixed cylinder 148 is fixedly connected to the second rain shield 1410 through a slidingly connected second push plate 149, the second rain shield 1410 is hinged to the inner top of the air outlet 10, and the second rain shield 1410 blocks rainwater at the air outlet 10; During use, the piston plate 142 slides and outputs the oil in the oil tank 143 to the interior of the first fixed cylinder 145 and the second fixed cylinder 148, so that the first push plate 146 drives the first rain shield 147 to rotate, and the second push plate 149 drives the second rain shield 1410 to rotate synchronously. When the wind blows on a rainy day and the wind blows obliquely with the rain, the first rain shield 147 and the second rain shield 1410 can adjust the shielding angle according to the change in the rain falling angle caused by the wind force, so that the rain is blocked outside the shell 1, and the wind can flow freely for heat dissipation, which can protect the energy storage battery 4 from rain without affecting the heat dissipation, thereby ensuring that the energy storage battery 4 can be in a good working condition on both sunny and rainy days, thereby improving the efficiency of energy storage and power generation.

[0025] Working principle: When using the micro off-grid energy storage solar power generation system with protective function, when it is windy but rainless, 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 electricity generated by the photovoltaic panel 2, so as to power the load at night or when the light is insufficient. The inverter control integrated machine 5 adjusts and controls the electricity output by the photovoltaic panel 2, realizes the charge and discharge management of the energy storage battery 4 group, prevents the energy storage battery 4 from being overcharged and over-discharged, and prolongs the service life of the energy storage battery 4. At the same time, the direct current output by the energy storage battery 4 group is converted into alternating current to meet the power demand of the AC load. The heat dissipation holes 8 on the mounting frame 3 are convenient for heat dissipation to avoid heat loss and affect the efficiency of power generation and energy storage. The heat dissipation fan 7 is driven by the motor 6 to rotate, and the air inlet 9 inputs flowing air. The air envelops the heat generated by the energy storage battery 4 and is discharged from the air outlet 10 for heat dissipation. Secondly, the anemometer 11 can detect the size of the natural wind force. When the anemometer 11 detects that the natural wind energy is sufficient, the use state of the cooling fan 7 is adjusted to reduce the energy consumption of the motor 6, and the wind speed of the cooling fan 7 can be slowed down, or the cooling fan 7 can be stopped, thereby saving energy and heat dissipation. The wind vane 139 is blown to point to the windward side. The wind vane 139 can ensure that the natural wind can be effectively collected and guided under various wind direction conditions. After the wind vane 139 rotates, it will synchronously drive the slide 135 to rotate synchronously through the column 136. The slide 135 drives the sleeve 132 to rotate through the slide rod 133. At this time, the first electromagnet 134 is in an unpowered state, and the second electromagnet 137 is in an energized state. The slide 135 and The upright column 136 is fixed by adsorption, and then when there is wind but no rain, the wind cap 138 is blown upward and moves up, which will synchronously drive the sliding rod 133 to slide freely on the sliding seat 135. After the sleeve 132 rotates, it will synchronously drive the shaft rod 1310 at the bottom to rotate. After the shaft rod 1310 rotates, the tooth plate 1311 rotates accordingly. The rotation direction of the tooth plate 1311 is consistent with the wind direction. After the tooth plate 1311 rotates, it will mesh with the small gear 1312 at the corresponding position on the air guide box 131, so as to rotate the flap 1313 in the corresponding air supply port 1314, so that according to the change of wind direction, the direction and angle of the flap 1313 are always aligned with the wind direction, so that the air supply port 1314 can introduce natural wind to the greatest extent, which is beneficial to the energy storage and power generation work of the energy storage battery 4. Moreover, when there is no rain but wind, when the upright post 136 slides, it will synchronously drive the truss 141 to move accordingly, and the third electromagnet 144 is in an off-state. When it is rainy and windy, the rain sensor 12 can activate the protective component to protect the energy storage battery 4 when it rains. At this time, the first electromagnet 134 will also be in an energized state, the sleeve 132 and the slide bar 133 are adsorbed and fixed, and the second electromagnet 137 is in an off-state. When the shaft rod 1310 is driven to slide by the wind cap 138 again, the shaft rod 1310 will move on the slide seat 135, and the third electromagnet 144 will be in an energized state, so that when the shaft rod 1310 slides, the truss 141 will drive the piston plate 142 to slide synchronously in the oil tank 143, and the piston plate 142 will slide and push the oil tank The oil in 143 is output to the interior of the first fixed cylinder 145 and the second fixed cylinder 148, so that the first push plate 146 drives the first rain shield 147 to rotate, and the second push plate 149 drives the second rain shield 1410 to rotate synchronously. When the wind blows on a rainy day and the wind blows obliquely with the rain, the first rain shield 147 and the second rain shield 1410 can adjust the shielding angle according to the change in the rain falling angle caused by the wind force, so that the rain is blocked outside the shell 1 to avoid rain infiltration and affect the normal energy storage and power generation work. The wind can flow freely to dissipate heat, which can protect the energy storage battery 4 from rain without affecting the heat dissipation, thereby ensuring that the energy storage battery 4 can be in a good working condition on both sunny and rainy days, thereby improving the efficiency of energy storage and power generation.
