[0015] Technical effects and advantages of the present invention: 1. In the actual operation of the present invention, since the multiple flexible solar panels are distributed in an umbrella shape, when the driving mechanism drives the lower ring body to move up and down, the support frame is pushed by the support rod to support the bottom of the flexible solar panel at different inclinations, so that the opening degree of the multiple flexible solar panels in the umbrella shape can be changed, thereby adapting to sunlight at different angles and absorbing solar energy to the maximum extent. The multiple flexible solar panels that are supported can have a sunshade effect.

[0016] 2. When the sun rises or sets, multiple flexible solar panels are retracted, and the outer sides of the flexible solar panels can form a vertical angle with the irradiated sunlight to receive sunlight when it rises and sets. As the direct angle of the sun gradually increases, the multiple flexible solar panels can be gradually opened through the driving mechanism to maximize the propping up of the umbrella-shaped assembly, making it easier for the entire umbrella surface to receive sunlight, thereby reducing the deviation in the intensity of solar energy received by multiple flexible solar panels throughout the day and being able to charge the battery evenly.

[0017] 3. The electric energy converted by multiple flexible solar panels can be stored in batteries, which can provide energy for the lighting lamps. Moreover, since the lighting lamps are located under the umbrella-shaped components, the conical range of the lighting lamps can be changed as the umbrella-shaped components are retracted and extended, so as to expand or reduce the lighting range and facilitate adjustment in actual use.

[0018] 4. Furthermore, when it is windy or rainy, the rain sensor and the wind speed sensor will transmit signals to the controller, and the controller will control the second electric push rod to retract. By completely retracting the multiple flexible solar panels, the contact area between the overall device and the wind can be reduced, so that the device is in a relatively stable state in windy weather, avoiding the wind from causing the multiple flexible solar panels to shake, and the lighting lamp at the bottom of the umbrella-shaped component can also be retracted to protect the lighting lamp.

[0019] 5. When it rains, the multiple flexible solar panels can be retracted so that rainwater can be discharged downward along the slope of the multiple flexible solar panels, thereby preventing rainwater from accumulating on the flexible solar panels and affecting the next reception of solar energy.

[0020] 6. In the actual operation of the present invention, the fan can blow for the inside of the cavity, and the excess wind force can be discharged from the sliding groove, thereby completing the heat discharge and heat dissipation work. At the same time, when the multiple flexible solar panels are retracted and stored, the end of the support frame will rotate downward, thereby driving the lighting lamp toward the direction of the sliding groove. Through the action of wind force, the dust and impurities adhering to the outside of the lighting lamp can be cleaned to avoid affecting the brightness of the lighting lamp.

DETAILED DESCRIPTION

[0029] The present invention provides Figure 1 to Figure 7A photovoltaic energy storage battery device is shown, including an energy storage device, an expansion mechanism is arranged on the outside of the energy storage device, the expansion mechanism includes a main pole 2, an umbrella-shaped component is arranged on the main pole 2, the umbrella-shaped component can be opened and closed, and a lighting mechanism is installed on the bottom surface of the umbrella-shaped component. The lighting mechanism is used to illuminate the area around the main pole 2, and the lighting mechanism includes a lighting lamp 16.

[0030] The energy storage device includes a battery, which is fixed inside the main rod 2. A door panel 25 is hinged at the bottom end of the outer side of the main rod 2. A mechanical lock 26 is provided on the door panel 25. A base 1 is fixed to the bottom end of the main rod 2.

[0031] The base 1 is used to support the main pole 2 and increase the contact area with the ground, so that the main pole 2 and the mechanism on the main pole 2 can be placed and installed more smoothly. At the same time, by opening the mechanical lock 26, the door panel 25 can be rotated and opened, which is convenient for personnel to inspect and replace the internal battery, and is convenient for installation and subsequent use.

[0032] The umbrella-shaped assembly includes a flexible solar panel 11, which is connected to the main pole 2 through an umbrella rib, and the umbrella rib includes an upper ring body 7 and a lower ring body 6 arranged up and down, wherein the upper ring body 7 is fixed on the main pole 2; The lower ring body 6 is slidable up and down along the height direction of the main rod 2; When the lower ring body 6 slides up and down along the height direction of the main rod 2, it controls the opening and closing of the umbrella-shaped assembly respectively; Specifically, the upper ring body 7 is located above the lower ring body 6, and an arc rod 8 is hinged on the upper ring body 7. The end of the arc rod 8 away from the upper ring body 7 is hinged with a support frame 10, and the lower ring body 6 is hinged with a support rod 9. The middle part below the support frame 10 is hinged with the support rod 9. A driving mechanism for driving the lower ring body 6 to move is provided in the main rod 2, and the lighting lamp 16 is fixed to the bottom of the support frame 10 on one side away from the main rod 2; There are multiple flexible solar panels 11, and the multiple flexible solar panels 11 are in the shape of an umbrella when unfolded. In the actual operation of the present invention, the multiple flexible solar panels 11 are connected to the battery, and the multiple flexible solar panels 11 in the shape of an umbrella receive solar energy at the same time and convert light energy into electrical energy. The electrical energy can be input into the battery for storage through wires, and the battery can provide starting energy for the lighting mechanism and the driving mechanism.

[0033] In the actual operation of the present invention, since the multiple flexible solar panels 11 are distributed in an umbrella shape, when the driving mechanism drives the lower ring body 6 to move up and down, the support frame 10 is pushed by the support rod 9 to support the bottom of the flexible solar panel 11 at different inclinations, so that the opening degree of the multiple flexible solar panels 11 in the umbrella shape can be changed, so as to adapt to sunlight exposure at different angles and absorb solar energy to the maximum extent, and the multiple flexible solar panels 11 that are supported can have a sunshade effect.

[0034] For example, when the sun rises or sets, the multiple flexible solar panels 11 are retracted so that the outer sides of the flexible solar panels 11 can form a vertical angle with the irradiated sunlight to receive the sunlight when it rises and sets, and as the direct angle of the sun gradually increases, the multiple flexible solar panels 11 can be gradually opened by the driving mechanism to maximize the propping up of the umbrella-shaped assembly, making it easier for the entire umbrella surface to receive sunlight, so that the intensity deviation of the solar energy received by the multiple flexible solar panels 11 during the day is small, and the battery can be charged evenly.

[0035] The time for the driving mechanism to drive the lower ring body 6 to move up and down can be set according to the sunrise time in different regions, so that the multiple flexible solar panels 11 can automatically open and close at different times in a day to adapt to different solar radiation angles. For example, when the sun is in the morning to noon, the multiple flexible solar panels 11 are slowly opened to the maximum extent at a fixed time. When the sun is in the noon to sunset, the multiple flexible solar panels 11 are slowly closed over time to adapt to the light angles at different times.

[0036] It should be noted that the energy storage device and the central control system can be connected by remote signal, and the energy storage device can be remotely controlled to be opened and closed at different times by the central control system to adapt to solar illumination at different angles.

[0037] The central control system can establish a remote signal connection with a single or multiple energy storage devices to simultaneously control multiple energy storage devices to open or close.

[0038] When the electric energy converted by multiple flexible solar panels 11 can be stored in the battery, the battery can provide energy for the lighting lamp 16. Since the lighting lamp 16 is located under the umbrella-shaped component, the conical range illuminated by the lighting lamp 16 can be changed as the umbrella-shaped component is retracted and extended, which is convenient for adjustment in actual use.

[0039] Specifically, a spring telescopic rod 13 is fixed to the top outer side of the main rod 2, a through slot 15 is opened along the height direction of the arc rod 8, one end of the spring telescopic rod 13 extends into the through slot 15, and movable slots 14 are provided on both sides of the through slot 15, and sliding rods are fixed on both sides of the inserted end of the spring telescopic rod 13, and the two sliding rods are slidably fitted in the corresponding movable slots 14 respectively.

[0040] The driving mechanism includes a second electric push rod 21, a cavity 17 is opened inside the main rod 2, and a plurality of sliding grooves 4 are opened outside the main rod 2. The plurality of sliding grooves 4 are connected to the cavity 17. A fixed plate 20 is fixed to the bottom end of the cavity 17. The second electric push rod 21 is fixed to the top of the fixed plate 20. A lifting plate 18 is fixed to the top of the second electric push rod 21. A plurality of sliding blocks 19 are fixed to the outside of the lifting plate 18. The plurality of sliding blocks 19 are slidably fitted in the corresponding sliding grooves 4, and the inner ring of the lower ring body 6 and the ends of the plurality of sliding blocks 19 are fixedly connected.

[0041] It should be noted that the driving mechanism may also use an electric cylinder, which is not limited here.

[0042] A first electric push rod 12 is embedded in the top of the main rod 2, and a conical cover 3 is fixed to the top of the first electric push rod 12. The tip of the conical cover 3 is set upward, the conical cover 3 is set to be transparent, and a light intensity sensor is set inside the conical cover 3. A rain sensor and a wind speed sensor are also set at the top of the main rod 2. It should be noted that the light intensity sensor, the rain sensor and the wind speed sensor are all connected to the controller, and the controller is connected to the first electric push rod 12 and the second electric push rod 21.

[0043] The conical cover 3 blocks the areas not covered by the multiple flexible solar panels 11, thereby improving the water-leakage resistance and sun-shading performance of the device. The conical cover 3 is driven to rise and fall by extending and descending the first electric push rod 12, thereby matching the height of the top of the flexible solar panel 11.

[0044] Furthermore, when it is windy or rainy, the rainfall sensor and the wind speed sensor will transmit signals to the controller, and the controller will control the second electric push rod 21 to retract. By completely retracting the multiple flexible solar panels 11, the contact area between the overall device and the wind can be reduced, so that the device is in a relatively stable state in windy weather, avoiding the wind from causing the multiple flexible solar panels 11 to shake, and the lighting lamp 16 at the bottom of the umbrella-shaped component can also be retracted to protect the lighting lamp 16.

[0045] In rainy weather, the multiple flexible solar panels 11 are contracted so that rainwater can be discharged downward along the slopes of the multiple flexible solar panels 11, thereby preventing rainwater from accumulating on the flexible solar panels 11 and affecting the next reception of solar energy.

[0046] By extending the second electric push rod 21 upward, the lifting plate 18 can be driven to rise, thereby driving the lower ring body 6 to rise through the lifting plate 18. The lower ring body 6 can make the support frame 10 rotate and rise through the support rod 9 to support the flexible solar panel 11. Similarly, the second electric push rod 21 retracts downward, which can drive the support frame 10 to rotate and descend, thereby retracting the flexible solar panel 11.

[0047] A vent 5 is provided in the middle of the outer side of the main rod 2, and the vent 5 is connected to the inside of the cavity 17. A support net 22 is provided under the fixed plate 20, and a fan 23 is fixed on the support net 22. The fixed plate 20 is fixed on the inner wall of the cavity 17, and the air outlet of the fan 23 is arranged upward. Through the vent 5, the outside air can pass through the support net 22, so that the outside air can correspond to the air inlet of the fan 23.

[0048] In the actual operation of the present invention, the fan 23 can blow for the inside of the cavity 17, and the excess wind force can be discharged from the sliding groove 4, so as to complete the heat discharge and heat dissipation. At the same time, when the multiple flexible solar panels 11 are retracted and stored, the end of the support frame 10 will rotate downward, thereby driving the lighting lamp 16 to move closer to the sliding groove 4. Through the action of wind force, the dust and impurities adhering to the outside of the lighting lamp 16 can be cleaned to avoid affecting the brightness of the lighting lamp 16.

[0049] A filter is fixed inside the vent 5, and the vent 5 is located below the support net 22. A gap is left between the fixing plate 20 and the support net 22, and the filter can prevent external dust from entering.

[0050] The lifting plate 18, the fixing plate 20 and the supporting net 22 are all provided with wire holes 24 for passing cables, so that the flexible solar panel 11 can be connected to the battery through cables. It should be noted that the number and position of the wire holes 24 can be set as needed.

[0051] The present invention also discloses a photovoltaic energy storage system, which includes: a sensor module (light intensity sensor, rain sensor, wind speed sensor) and a controller, and the controller is used to control the opening and closing of the umbrella-shaped component.

[0052] Specifically, the lighting lamp 16 is detachably mounted on the lower surface of the umbrella-shaped component, the controller is fixed inside the main pole 2, and after the flexible solar panel 11 receives solar energy, the solar energy converter converts the solar energy into electrical energy and stores it in the battery, which powers the lighting lamp 16.

[0053] The light intensity sensor is used to monitor the light intensity and transmit the light intensity signal to the controller. The controller controls the driving mechanism to drive the umbrella-shaped component to open and close. At the same time, the remaining battery power is judged according to the internal resistance test method and other methods to adjust the angle of the flexible solar panel 11 as needed to reduce the light intensity and avoid overheating or overcharging of the photovoltaic system panel.

[0054] Similarly, the rain sensor monitors the rain and transmits the signal to the controller. The controller controls the driving mechanism to drive the umbrella assembly to contract, so that the rain can fall smoothly through the umbrella assembly to avoid accumulation. At the same time, it also avoids the phenomenon of excessive rain hitting the surface of the umbrella assembly to reduce the service life of the umbrella assembly.

[0055] The wind speed sensor monitors the wind force and transmits the signal to the controller, which controls the driving mechanism to drive the umbrella-shaped component to retract, thereby avoiding damage to the device and reducing the impact of wind force.

[0056] At the same time, the contraction degree of the umbrella-shaped component can be controlled according to the wind force monitored by the wind speed sensor to take into account both receiving solar energy and protecting against wind.
