DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0016] The utility model provides a photovoltaic energy storage device, including an energy storage box 1, wherein an energy storage battery is arranged in the energy storage box 1, and an inclined photovoltaic panel assembly is arranged on the top of the energy storage box 1, wherein the photovoltaic panel assembly is electrically connected to the energy storage battery, and wherein the photovoltaic panel assembly comprises two parallel support rods 2, a support 3 and two groups of photovoltaic panels 4, wherein one end of the support rod 2 is rotatably mounted on the support 3 via a connecting rod 1 5, and the support 3 is fixedly connected to the top of the energy storage box 1, and the other ends of the two support rods 2 are connected via a connecting rod 2 6, and the connecting rod 2 6 is connected to the top of the energy storage box 1 via a support rod 7, and the two groups of photovoltaic panels 4 are rotatably connected via a connecting shaft 8, wherein one end of one photovoltaic panel 4 is fixedly arranged on the support rod 2, and one end of the other photovoltaic panel 4 and the connecting shaft 8 are slidably mounted on the support rod 2 via a sliding sleeve 9, and each group of photovoltaic panels 4 comprises photovoltaic panels 41 hinged in pairs via hinges.

[0017] like Figure 1 As shown, by fixing one end of one group of photovoltaic panels 4 on the support rod 2, another photovoltaic panel 4 is slidably installed on the support rod 2 through the sliding sleeve 9. When unfolding and using, the other photovoltaic panel 4 can be pushed along the support rod 2 in the direction of the support 3. Under the action of the sliding sleeve 9, the photovoltaic panels 41 are unfolded one by one. Similarly, when not in use, the other photovoltaic panel 4 is pushed in the opposite direction to fold and shrink it to prevent debris and other impurities from hitting the photovoltaic panel 41 and causing damage to it.

[0018] The middle parts of both end surfaces of two adjacent photovoltaic panels 41 are connected with connecting rods 42 , and the connecting rods 42 are connected by pins.

[0019] like Figure 2 As shown, when two adjacent photovoltaic panels 41 are deployed, the connecting rod 42 can increase their stability after deployment.

[0020] A thread 10 is provided on one end of the support rod 2 close to the connecting rod 6, the major diameter of the thread 10 is larger than the diameter of the support rod 2, and the inner diameter of the sleeve 9 is larger than the major diameter of the thread 10, so that the sleeve 9 can pass through the thread 10, and a threaded sleeve 11 adapted to the thread 10 is provided on one end of the support rod 2 close to the support 3.

[0021] like Figure 2 As shown, when the photovoltaic panel 41 is retracted, the photovoltaic panel 41 is retracted along the support rod 2 between the fixed end of the photovoltaic panel 4 and the thread 10, and then the threaded sleeve 11 is installed on the thread 10 to fix the photovoltaic panel 4, thereby preventing the photovoltaic panel 41 from sliding.

[0022] The support rod 2 is provided with a limiting hole at one end close to the support 3, and a fixing pin 12 is arranged in the limiting hole.

[0023] like Figure 1As shown, when the photovoltaic panel 41 is unfolded, in order to prevent the photovoltaic panel 41 from moving along the support rod 2, the photovoltaic panel 41 is fully unfolded. At this time, the sliding sleeve 9 close to one end of the support 3 just passes through the limiting hole, and then is installed in the limiting hole through the fixing pin 12 to limit the sliding sleeve 9, which can effectively prevent the sliding sleeve 9 from sliding and causing the photovoltaic panel 41 to move.

[0024] There are two support rods 7, one end of the two support rods 7 is rotatably mounted on the two end surfaces of the connecting rod 6 respectively, and the other ends of the two support rods 7 are connected by a connecting column 13. Two sets of positioning guide rails 14 are fixedly provided on the top of the energy storage box 1. A plurality of limiting grooves 15 are evenly opened on the positioning guide rails 14. The connecting column 13 is arranged in the limiting groove 15, and the connecting column 13 is stuck in the limiting groove 15 for fixing the support rod 7.

[0025] like Figure 2 As shown, when the inclination angle of the photovoltaic panel assembly needs to be adjusted, the connecting column 13 is placed in different limit grooves 15 by controlling the support rod 7 to change the inclination angle of the support rod 2 and indirectly change the inclination of the photovoltaic panel assembly installation.

[0026] The top of the energy storage box 1 is provided with a receiving groove 16 for receiving the photovoltaic panel 4 .

[0027] like Figure 1 and 2 As shown, after the photovoltaic panel 4 is shrunk and fixed, the control support rod 7 can be lifted upward to disengage the connecting column 13 from the limiting groove 15, and the support rod 7 and the connecting column 13 can be rotated to the top of the support frame 2, and the photovoltaic component 4 falls into the receiving groove 16, which can effectively prevent debris, hail, etc. from hitting the outer surface of the photovoltaic panel 41, thereby increasing the service life of the photovoltaic panel 41.

[0028] Principle of use: When the photovoltaic panel 41 is needed, another photovoltaic panel 4 can be pushed toward the support 3 along the support rod 2. Under the action of the sliding sleeve 9, the photovoltaic panel 4 moves toward the support 3 until the sliding sleeve 9 near one end of the support 3 passes through the limiting hole. At this time, the photovoltaic panel 41 is fully unfolded and then installed on the limiting hole through the fixing pin 12 to limit the sliding sleeve 9.

[0029] When the inclination angle of the photovoltaic panel 4 needs to be adjusted, the control support rod 7 is lifted to change the connection column 13 in different limit grooves 15 of the positioning guide rail 14, thereby changing the inclination angle of the support rod 2 and indirectly changing the inclination of the photovoltaic panel assembly installation;

[0030] When not in use, take out the fixing pin 12, push the photovoltaic panel 4 in the opposite direction along the support frame 2 toward the support rod 7, push the two sliding sleeves 9 between the thread 10 and the fixed end of the photovoltaic panel 4, and use the threaded sleeve 11 to install it on the thread 10 to fix it. After fixing, lift the support rod 7 so that the connecting column 13 disengages from the limiting groove 15, rotate the support rod 7 and the connecting column 13 to the top of the support frame 2, and the photovoltaic panel 4 falls into the receiving groove 16 to complete the folding and contraction of the photovoltaic panel 4. In this embodiment, after the photovoltaic panel 4 is placed in the receiving groove 16, a cover plate can be covered on the receiving groove 16 to prevent impurities such as debris and hail from falling into the receiving groove 16. When the photovoltaic panel 4 is in use, the receiving groove 16 can also be covered with a cover plate to prevent impurities from entering.

[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
