[0014] The present invention also provides a control method for a photovoltaic energy storage and charging control device based on a new energy grid, comprising:

[0015] Step S1, during the day, the concave support frame rises in the installation cavity 1 in the support shell, so that the photovoltaic panel is separated from the side wall of the L-shaped shielding frame, and then the photovoltaic panel is adjusted to rotate along the rotation groove to form a certain angle with the concave support frame and face the sunlight, so as to cooperate with the photovoltaic panel to absorb sunlight and convert it into electrical energy, and then transmit the electrical energy to the battery assembly for storage;

[0016] Step S2, at night, first adjust the photovoltaic panel to be vertically parallel to one side of the support shell, and then adjust the concave support frame to descend in the installation cavity 1 of the support shell, driving the photovoltaic panel to fit on the side wall of the L-shaped shielding frame for shielding protection.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0031] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] Reference Figure 1-Figure 10The photovoltaic energy storage and charging control device based on the new energy grid comprises a support shell 1 with a sealed door, a plurality of L-shaped connecting frames 8 are fixed to the bottom of the support shell 1, and a connecting hole 81 is arranged on the L-shaped connecting frame 8, a pair of mirror-symmetrical mounting cavities 11 are arranged in the support shell 1, and a mounting cavity 2 12 is arranged in the support shell 1 and between the two mounting cavities 1 11, a battery assembly 2 is arranged between the inner side walls of the mounting cavity 2 12, a storage shell 7 with moisture-proof beads is arranged between the bottom wall of the mounting cavity 2 12 and the bottom of the support shell 1, a photovoltaic panel 3 electrically connected to the battery assembly 2 is arranged near the top side of the support shell 1, and a concave support frame 4 that can be raised and lowered is slidably connected to the mounting cavity 2. A rotating groove 41 is provided on the concave support frame 4 between the inner wall of the cavity 11 and the top of the support shell 1, and the photovoltaic panel 3 is rotatably arranged on the inner wall of the rotating groove 41 through a connecting shaft. A pair of driving parts 42 are installed between the bottom wall of the installation cavity 11 and the bottom of the concave support frame 4, and a pair of concave seats 6 are fixed on the side walls of the concave support frame 4. The concave seat 6 is connected with a driving part 61 through a rotating shaft, and the other end of the driving part 61 is connected with a concave seat 62 fixed on the photovoltaic panel 3 through a rotating shaft. The support shell 1 is provided with an L-shaped slide groove 13 connected to the inside of the installation cavity 11, which is used to cooperate with the driving part 61 to lift and lower in the installation cavity 11.

[0033] The above technical solution realizes the angle adjustment of the photovoltaic panel 3 by starting the driving part 2 61 using the cylinder. As the driving part 2 61 is extended and retracted, the photovoltaic panel 3 begins to rotate along the rotating groove 41 on the concave support frame 4. The rotating groove 41 provides a rotation trajectory and space for the photovoltaic panel 3, ensuring that the photovoltaic panel 3 can rotate smoothly and steadily during the adjustment process. Through the extension and retraction action of the driving part 2 61, the angle between the photovoltaic panel 3 and the concave support frame 4 gradually changes. This angle adjustment enables the photovoltaic panel 3 to flexibly adjust its angle facing the sunlight, thereby ensuring that the photovoltaic panel 3 can face the sunlight to the greatest extent at different times and lighting conditions. The more suitable the angle of the photovoltaic panel 3 facing the sunlight, the better the effect of absorbing sunlight, and the more electrical energy is converted. This design not only improves the efficiency of light energy conversion, but also makes the entire light storage and charging control device more intelligent and efficient. Finally, the sunlight absorbed by the photovoltaic panel 3 is efficiently converted into electrical energy and transmitted to the battery assembly 2 for storage.

[0034] Further, refer to Figure 1-Figure 3 and Figure 5 When the photovoltaic panel 3 rotates along the rotating groove 41 and is vertically parallel to one side of the supporting shell 1, L-shaped shielding frames 5 are provided on both sides of the supporting shell 1, which are used to cooperate with the photovoltaic panel 3 to fit with the inner wall of the L-shaped shielding frame 5 when descending, so as to shield the light-receiving surface of the photovoltaic panel 3 at night.

[0035] Such a technical solution is adopted because it is considered that at night, the photovoltaic panel 3 exposed outside the supporting shell 1 is easily invaded by mosquitoes and other creatures, which may damage the photovoltaic panel 3. Therefore, based on this problem, L-shaped shielding frames 5 corresponding to the photovoltaic panel 3 are designed on both sides of the supporting shell 1. When the driving part 2 61 of the cylinder drives the photovoltaic panel 3 to be vertically parallel to one side of the supporting shell 1, the driving part 1 42 of the cylinder can drive the concave supporting frame 4 to slide along the inner wall of the installation cavity 11 until the top wall of the concave supporting frame 4 is When it is attached to the top of the supporting shell 1, the movement of the driving part 42 is stopped. At this time, the side of the photovoltaic panel 3 that absorbs sunlight will be completely attached to the side wall of the L-shaped shielding frame 5, so that at night, the photovoltaic panel 3 can be prevented from being exposed to the outside for a long time and being damaged by mosquitoes and insects. At the same time, under the protection of the L-shaped shielding frame 5, the photovoltaic panel 3 can also reduce the pollution of environmental factors such as dew and dust on the surface of the photovoltaic panel 3 to a certain extent, thereby maintaining the cleanliness of the photovoltaic panel 3 and further improving the light energy absorption efficiency of the photovoltaic panel 3.

[0036] It should be noted that when the photovoltaic panel 3 needs to automatically detach from the side wall of the L-shaped shielding frame 5 and adjust to a preset angle during use during the day, the drive unit 1 42 and the drive unit 2 61 using the cylinder can be preset according to the changes in time throughout the year. For example, in spring and autumn, when the sunshine time is moderate, the drive unit 1 42 and the drive unit 2 61 can be preset to automatically start at sunrise in the morning to drive the photovoltaic panel 3 to detach from the L-shaped shielding frame 5 and adjust to a suitable angle. At sunset in the evening, the photovoltaic panel 3 is automatically lowered to be parallel to the support shell 1 and fit on the L-shaped shielding frame 5. In summer, due to the long sunshine time, the start of the drive unit 1 42 and the drive unit 2 61 can be preset in advance. time, and delay its stop time to ensure that the photovoltaic panel 3 can fully absorb sunlight. On the contrary, in winter, due to the shorter sunshine time, it is necessary to adjust the preset time of the driving unit 1 42 and the driving unit 2 61 respectively to adapt to the changes in lighting conditions. Of course, in addition to the time preset, the light intensity can also be monitored in real time through equipment such as light sensors, and the driving unit 1 42 and the driving unit 2 61 can be fine-tuned according to actual conditions. For example, on rainy days or when there is insufficient light, the angle of the photovoltaic panel 3 can be appropriately lowered to reduce the impact of shadows on the absorption of light energy. In clear weather, the photovoltaic panel 3 can be adjusted to the maximum angle to maximize the absorption of sunlight.

[0037] In a preferred embodiment, referring to Figure 4 , Figure 5 , Figure 6 and Fig. 9In the process of the concave support frame 4 sliding down along the inner wall of the installation cavity 11, the gas in the installation cavity 11 can be introduced into the storage shell 7. When the photovoltaic panel 3 is separated from the side wall of the L-shaped shielding frame 5 during the day and is located at the top and tilted, the side wall of the L-shaped shielding frame 5 is in contact with the side of the support shell 1. The L-shaped shielding frame 5 and the corresponding side of the support shell 1 are slidably connected. An L-shaped limit frame 51 is fixed between the side wall and the bottom wall of the installation cavity 11. A telescopic groove 52 is connected between the inside of the L-shaped limit frame 51 and the outside of the support shell 1. A slider 53 is fixed on one side of the L-shaped shielding frame 5 extending to the inside of the telescopic groove 52. A pair of springs 54 are fixed between the slider 53 and the side wall of the telescopic groove 52. An electromagnet 55 located between the two springs 54 is installed on the side wall of the telescopic groove 52, and an iron block 56 matching the electromagnet 55 is fixed on the slider 53.

[0038] Such a technical solution is adopted because it is considered that when the photovoltaic panel 3 is working during the day, it will be separated from the L-shaped shielding frame 5 and located above the L-shaped shielding frame 5. At this time, if the L-shaped shielding frame 5 located below the photovoltaic panel 3 is still exposed to the outside, it will not only occupy a large space, but also dust and impurities in the external environment may adhere to the side walls of the L-shaped shielding frame 5, so that the photovoltaic panel 3 needs to be vertically lowered to the side walls of the L-shaped shielding frame 5 for fitting at night. These dust and impurities may cause the surface of the photovoltaic panel 3 to be worn. Therefore, based on this, the L-shaped shielding frame 5 and the supporting shell 1 are optimized. When the photovoltaic panel 3 is working during the day, the electromagnet 55 is started to absorb the iron block 56, thereby The L-shaped shielding frame 5 can move smoothly along the telescopic groove 52 and finally fit onto one side of the supporting shell 1. This design not only reduces the space occupied by the L-shaped shielding frame 5 when not in use during the day, making the entire device more compact, but also effectively avoids the side walls of the L-shaped shielding frame 5 from being exposed, thereby reducing the adhesion of dust and impurities. In this way, when the photovoltaic panel 3 needs to fit onto the side wall of the L-shaped shielding frame 5 at night, there will be no wear problems due to the presence of dust and impurities. Compared with the fixed design, this sliding design not only optimizes space utilization, but also improves the service life of the photovoltaic panel 3 and the L-shaped shielding frame 5, and enhances the stability and reliability of the entire light storage and charging control device.

[0039] In a preferred embodiment, referring to Figure 3 and Fig. 9 A gap space is reserved between the battery assembly 2 and the bottom wall of the second installation cavity 12 , and air guide holes 71 are evenly arranged between the top wall of the storage shell 7 and the bottom wall of the second installation cavity 12 .

[0040] Such a technical solution is adopted in view of the fact that the battery assembly 2 is more sensitive to environmental conditions, especially humidity conditions. Excessive humidity may cause the battery assembly 2 to get damp, thereby affecting the normal operation of the battery assembly 2 and even causing safety hazards. In the present invention, a gap space is reserved between the battery assembly 2 and the bottom wall of the second installation cavity 12. The main purpose of this design is to provide the battery assembly 2 with a space isolated from the bottom wall of the second installation cavity 12, thereby reducing the risk of the battery assembly 2 getting damp due to high humidity in the bottom wall. At the same time, the storage shell 7 connected to the bottom center of the support shell 1 is filled with moisture-proof beads. These moisture-proof beads can absorb moisture in the second installation cavity 12 through the air guide holes 71, thereby further reducing the humidity level in the second installation cavity 12, providing a dry and stable working environment for the battery assembly 2, effectively reducing the risk of the battery assembly 2 getting damp, and improving the reliability and safety of the entire light storage and charging control device.

[0041] In a preferred embodiment, referring to Figure 3 The bottom of the storage shell 7 is connected to a pair of air guide pipes 72, and the other end of the air guide pipes 72 is connected to an air guide plate 73, and the air guide plate 73 is connected to the bottom wall of the installation cavity 11.

[0042] Such a technical solution is adopted in consideration of the fact that the moisture-proof beads filled in the material storage shell 7 will become heavier after absorbing moisture, and long-term standing may cause the moisture-proof beads to settle to the bottom of the material storage shell 7 and fail to fully play their role. Therefore, based on this, through the setting of the air guide tube 72, the process of the concave support frame 4 sliding along the inner wall of the installation cavity 11 when descending can be fully utilized, and the compressed gas in the installation cavity 11 is input into the interior of the material storage shell 7 through the air guide tube 72, so that the material storage shell 7, under the action of the flow of gas, helps to improve the uniform distribution of the moisture-proof beads. In this way, not only can the moisture-proof beads be prevented from settling due to long-term standing, but it can also ensure that the moisture-proof beads in the material storage shell 7 can fully exert the moisture-proof effect, ensuring that the battery assembly 2 in the installation cavity 2 12 can obtain long-term and effective moisture-proof protection.

[0043] In a preferred embodiment, referring to Figure 7-Figure 9 The air guide pipe 72 is connected to an air guide cylinder 74 connected to the bottom of the storage shell 7. A transmission rod 75 is rotatably arranged between the bottom of the air guide cylinder 74 and the bottom wall of the storage shell 7. A plurality of air guide sheets 76 that are circumferential and fit with the inner wall of the air guide cylinder 74 are fixed to the transmission rod 75. A plurality of circumferentially distributed connecting strips 77 are fixed to one end of the transmission rod 75 corresponding to the inside of the storage shell 7.

[0044] According to the present invention, when the transmission rod 75 cooperates with the connecting strip 77 to rotate in the storage shell 7, the moisture-proof beads inside the storage shell 7 can be stirred. This design not only helps to improve the use efficiency of the moisture-proof beads, but also enables the air in the storage shell 7 to better contact with the moisture-proof beads, thereby accelerating the absorption and diffusion process of moisture, which not only reduces the accumulation of moisture in the storage shell 7, but also enables the moisture absorption capacity of the moisture-proof beads to be more fully utilized.

[0045] The transmission rod 75 in the above technical solution utilizes the process of the concave support frame 4 sliding down along the inner wall of the installation cavity 11 during transmission, and the compressed gas in the installation cavity 2 12 enters the interior of the gas cylinder 74 along the gas guide pipe 72 through the gas guide plate 73, and is used to drive the gas guide sheet 76 to rotate along the inner wall of the gas cylinder 74, so that the connecting strip 77 on the transmission rod 75 stirs the moisture-proof beads filled in the storage shell 7. The advantage of this design is that it utilizes the energy during the descent of the concave support frame 4 and converts it into power to drive the transmission rod 75 to rotate, thereby realizing effective energy utilization and automatic operation of the system. In this way, it not only simplifies the system structure and reduces additional driving devices, but also improves the efficiency and reliability of the entire device.

[0046] The present invention also provides a control method for a photovoltaic energy storage and charging control device based on a new energy grid, comprising:

[0047] Step S1, during the day, the concave support frame 4 rises in the installation cavity 11 in the support shell 1, so that the photovoltaic panel 3 is separated from the side wall of the L-shaped shielding frame 5, and then the photovoltaic panel 3 is adjusted to rotate along the rotation groove 41 to form a certain angle with the concave support frame 4 and face the sunlight, so as to cooperate with the photovoltaic panel 3 to absorb sunlight and convert it into electrical energy, and then transmit the electrical energy to the battery assembly 2 for storage;

[0048] Step S2, at night, first adjust the photovoltaic panel 3 to be vertically parallel to one side of the support shell 1, and then adjust the concave support frame 4 to descend in the installation cavity 11 of the support shell 1, driving the photovoltaic panel 3 to fit on the side wall of the L-shaped shielding frame 5 for shielding protection.

[0049] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
