[0050] Currently, photovoltaic and energy storage systems with a capacity of 1 kilowatt or more are generally referred to as medium-sized photovoltaic and energy storage systems. Because these medium-sized systems require higher-power solar photovoltaic panels or need to increase the number of solar photovoltaic panels to improve power generation efficiency, the overall weight of the solar photovoltaic panels is heavier, reducing the system's ability to track sunlight, or even preventing it from doing so, thus resulting in lower power generation efficiency.

[0051] Therefore, in order to improve the light-tracking capability of medium and large-sized photovoltaic storage devices, the following is combined with... Figures 1 to 8 The structure and working principle of the optical storage device provided by this utility model are described in detail.

[0052] like Figures 1 to 5 As shown, a specific embodiment of this utility model provides a photovoltaic energy storage device. The device includes an energy storage mechanism; this mechanism includes a solar photovoltaic component 100, a rotating component 200, a supporting component 300, and an amplitude transformer 400; the rotating component 200 is used to rotate around its own axis; the supporting component 300 is mounted on the rotating component 200; one end of the supporting component 300 away from the rotating component 200 is rotatably engaged with the solar photovoltaic component 100 via a first rotating shaft; one end of the amplitude transformer 400 is connected to the supporting component 300, and the other end is connected to the solar photovoltaic component 100; the amplitude transformer 400 is used to drive the solar photovoltaic component 100 to rotate relative to the first rotating shaft; the axis of the first rotating shaft intersects the axis of the rotating component 200.

[0053] In the embodiment, the support component 300 can provide a mounting base for the solar photovoltaic component 100. The rotation component 200 can drive the solar photovoltaic component 100 to rotate around the axis of the rotation component 200 through the support component 300. The first rotating shaft can rotate the solar photovoltaic component 100 away from the end of the support component 300 far from the rotation component 200, and the amplitude component 400 can drive the solar photovoltaic component 100 to rotate relative to the first rotating shaft, wherein the axis of the first rotating shaft intersects the axis of the rotation component 200. In other words, through the cooperation of the rotation component 200 and the amplitude component 400, the solar photovoltaic component 100 can rotate around the axis of the rotation component 200 and also rotate around the axis of the first rotating shaft (intersecting the axis of the rotation component 200) relative to the support component 300. Such multi-directional adjustment capability enables the solar photovoltaic component 100 to capture sunlight more flexibly, and can maintain high power generation efficiency regardless of the change in the position of the sun, thereby solving the problem of poor light tracking capability of the medium and large-sized light storage devices in the prior art.

[0054] Specifically, the axis direction of the rotation component 200 is the up-down direction, and the axis direction of the first rotating shaft is the first direction in the horizontal plane.

[0055] Preferably, the first direction is perpendicular to the up-down direction.

[0056] Further, the light storage mechanism includes two solar photovoltaic components 100, and the two solar photovoltaic components 100 are symmetrically arranged on the support component 300. By increasing the number of solar photovoltaic components 100, the power generation efficiency can be improved. By symmetrically arranging the two solar photovoltaic components 100 on the support component 300, the installation stability of the light storage device can be improved.

[0057] Further, the light storage mechanism includes two amplitude components 400, and the two amplitude components 400 correspond to the two solar photovoltaic components 100 one-to-one. By arranging the amplitude components 400 corresponding to the two solar photovoltaic components 100 one-to-one, the two solar photovoltaic components 100 can be rotated relative to the support component 300 around the first direction respectively, thereby improving the power generation efficiency of the single solar photovoltaic component 100.

[0058] As shown in FIG. 1, Figure 3 Further, the solar photovoltaic component 100 further includes a mounting bracket 120, the mounting bracket 120 is rotatably connected to the support component 300 through the first rotating shaft, and the two ends of the mounting bracket 120 are respectively connected to the first solar photovoltaic assembly 110 of the two solar photovoltaic components 100. Specifically, the mounting bracket 120 is rotatably connected to the mounting platform 310 of the support component 300 through the first rotating shaft.

[0059] In some embodiments, the amplitude-changing component 400 comprises a rotary driving assembly; a mounting end of the rotary driving assembly is fixedly mounted on the mounting platform 310 of the support component 300, a rotating shaft of the rotary driving assembly is rotatably assembled on the connecting portion of the mounting platform 310 of the support component 300, and the rotary driving assembly is connected with the solar photovoltaic component 100 through the first rotating shaft, for driving the solar photovoltaic component 100 to rotate relative to the first rotating shaft.

[0060] Further, the rotary driving assembly comprises a motor or a rotary cylinder.

[0061] As shown in FIG. 4, Figures 1 to 5 In some other embodiments, the amplitude-changing component 400 comprises a first telescopic assembly; the first telescopic assembly is used for telescoping along the axis of the slewing component 200; one end of the first telescopic assembly is hingedly connected with the support component 300, and the other end is hingedly connected with the solar photovoltaic component 100. Through the telescoping movement of the first telescopic assembly, the solar photovoltaic component 100 can be rotated relative to the support component 300 around the axis direction (i.e., the first direction) of the first rotating shaft, so as to improve the rotation stability of the solar photovoltaic component 100. Compared with the motor, the first telescopic assembly can bear a larger load, and the power generation efficiency of the solar photovoltaic component 100 can be improved by increasing the number of the solar photovoltaic panels 112.

[0062] Further, the first telescopic assembly comprises a cylinder or a hydraulic cylinder.

[0063] As shown in FIG. 4, Figures 1 to 5 In some embodiments, the solar photovoltaic component 100 comprises a plurality of solar photovoltaic assemblies 110; two adjacent solar photovoltaic assemblies 110 are connected through a connecting structure, so as to switch the plurality of solar photovoltaic assemblies 110 between the folded state and the unfolded state. In this way, the power generation efficiency of the device can be improved by increasing the number of the solar photovoltaic assemblies 110. By providing the connecting structure, the plurality of solar photovoltaic assemblies 110 can be switched between the folded state and the unfolded state, so as to reduce the storage volume of the light storage device, reduce the storage space of the light storage device, and reduce the transportation cost and the difficulty of carrying.

[0064] It should be noted that the switching between the folded state and the unfolded state can be realized in a manual manner. The switching between the folded state and the unfolded state can also be realized in an electric manner. In order to save manpower, it is preferred that the switching between the folded state and the unfolded state is realized in an electric manner.

[0065] As shown in FIG. 4, Figure 1 , Figure 4 and Figure 5As shown, the solar photovoltaic component 100 further includes a sliding connection assembly 130; two adjacent solar photovoltaic components 110 are slidably connected along the axial direction of the first rotating shaft via the sliding connection assembly 130, allowing multiple solar photovoltaic components 110 to switch between a folded state and an unfolded state. By setting the sliding connection assembly 130, not only can the solar photovoltaic component 100 switch between a folded state and an unfolded state, but it also serves to support the solar photovoltaic components 110 in the unfolded state. Setting the sliding connection assembly 130 also improves the stability of the solar photovoltaic components 110 during state switching.

[0066] Furthermore, the solar photovoltaic module 110 includes a photovoltaic support 111 and at least one solar photovoltaic panel 112; the solar photovoltaic panel 112 is disposed on the photovoltaic support 111; two adjacent photovoltaic supports 111 are slidably engaged along the axial direction of the first rotating shaft by a sliding connection assembly 130.

[0067] Furthermore, the sliding connection assembly 130 includes a protruding ridge 131 and a sliding groove 132; the protruding ridge 131 and the sliding groove 132 are respectively formed on two adjacent solar photovoltaic modules 110 along the axial direction of the first rotating shaft, so that the protruding ridge 131 and the sliding groove 132 slide in engagement.

[0068] like Figure 5 As shown, the photovoltaic support 111 further includes two crossbeams 113; the two crossbeams 113 are spaced apart along a direction perpendicular to the axis of the first rotating shaft; both ends of the solar photovoltaic panel 112 are connected to the two crossbeams 113 respectively; the upper end of the side of the crossbeam 113 facing the solar photovoltaic panel 112 has one of a groove 132 or a protrusion 131 formed along the axis of the first rotating shaft; the lower end of the side of the crossbeam 113 away from the solar photovoltaic panel 112 has the other of a groove 132 or a protrusion 131 formed along the axis of the first rotating shaft. The crossbeams 113 on the same side of adjacent photovoltaic supports 111 are arranged vertically and slide in contact with each other along the axis of the first rotating shaft through the groove 132 and the protrusion 131.

[0069] Furthermore, the solar energy storage mechanism also includes an extension and retraction drive component 500; the extension and retraction drive component 500 is connected to the solar photovoltaic module 110 and is used to drive two adjacent solar photovoltaic modules 110 to reciprocate along the axial direction of the first rotating shaft. This design can improve the extension and retraction efficiency of the solar photovoltaic module 100, save manpower, and increase the switching speed.

[0070] Exemplarily, the deployment and retraction driving component 500 comprises a plurality of first folding and retracting assemblies; each of the plurality of first folding and retracting assemblies is mounted on the mounting platform 310 of the support component 300. The plurality of first folding and retracting assemblies correspond to the plurality of solar photovoltaic assemblies 110 one by one. The mounting end of the first folding and retracting assembly is mounted on the mounting platform 310 of the support component 300, and the other end is connected with the corresponding solar photovoltaic assembly 110. When the plurality of first folding and retracting assemblies are extended, the solar photovoltaic component 100 is in the unfolded state. When the plurality of first folding and retracting assemblies are retracted, the solar photovoltaic component 100 is in the folded state. Understandably, the extension and retraction of the plurality of first folding and retracting assemblies will not interfere with the solar photovoltaic assemblies 110.

[0071] Exemplarily, the deployment and retraction driving component 500 comprises a plurality of retracting driving assemblies; the plurality of retracting driving assemblies correspond to the plurality of solar photovoltaic assemblies 110 which need to be unfolded or folded one by one; the retracting driving assembly is used to extend and retract along the axis direction of the first rotating shaft, so as to drive the corresponding solar photovoltaic assembly 110 to reciprocate along the axis direction of the first rotating shaft.

[0072] Preferably, the retracting driving assembly comprises an electric push rod.

[0073] As shown in Figure 7 and Figure 8 Exemplarily, the deployment and retraction driving component 500 comprises a second extending rope wheel 510, a second retracting rope wheel 520 and a deployment and retraction driving assembly 530; the fixed pulley of the second extending rope wheel 510 is mounted on the end of the solar photovoltaic assembly 110 away from the support component 300, and the two ends of the rope row of the second extending rope wheel 510 are connected with the adjacent two solar photovoltaic assemblies 110 respectively. The fixed pulley of the second retracting rope wheel 520 is mounted on the end of the solar photovoltaic assembly 110 close to the support component 300, and the two ends of the rope row of the second retracting rope wheel 520 are connected with the adjacent two solar photovoltaic assemblies 110 respectively. The deployment and retraction driving assembly 530 is connected with the solar photovoltaic assembly 110, and is used to drive the plurality of solar photovoltaic assemblies 110 to unfold along the axis direction of the first rotating shaft through the second extending rope wheel, and is also used to drive the plurality of solar photovoltaic assemblies 110 to fold along the axis direction of the first rotating shaft through the second retracting rope wheel 520. In this way, the use of a plurality of driving structures to drive the solar photovoltaic assembly 110 to move along the axis direction of the first rotating shaft can be avoided, and the cost and weight can be reduced. By arranging the second extending rope wheel 510 and the second retracting rope wheel 520, the movement stability of the solar photovoltaic assembly 110 can be improved.

[0074] Preferably, the deployment and retraction driving assembly 530 comprises a hydraulic cylinder or a pneumatic cylinder.

[0075] As shown in Figure 7As shown, preferably, the extension and retraction driving assembly 530 includes a winch driving member 531, a winch drum 532, a third extension rope 533, and a third retraction rope 534. The winch driving member 531 is mounted on the mounting platform 310 of the support member 300 and is connected with the winch drum 532 for driving the winch drum 532 to rotate. The fixed pulley of the third extension rope 533 is mounted on the second solar photovoltaic module 110, and one end of the rope of the third extension rope 533 is connected with the end of the second solar photovoltaic module 110 close to the support member 300, and the other end is wound on the winch drum 532. One end of the third retraction rope 534 is connected with the second solar photovoltaic module 110, and the other end is wound on the winch drum 532.

[0076] When the winch driving member 531 drives the winch drum to rotate counterclockwise, the rope of the third extension rope 533 moves to the left, and the extension of the plurality of solar photovoltaic modules 110 is realized. When the winch driving member 531 drives the winch drum to rotate clockwise, the third retraction rope 534 moves to the left, and the retraction of the plurality of solar photovoltaic modules 110 is realized.

[0077] As shown in Figure 3 and Figure 6 In some embodiments, the support member 300 includes a mounting platform 310 and a telescopic support assembly 320. The mounting platform 310 is rotationally connected with the solar photovoltaic member 100 through a first rotation shaft. One end of the telescopic support assembly 320 is connected with the mounting platform 310, and the other end is connected with the rotary member 200. The telescopic support assembly 320 is used to drive the solar photovoltaic member 100 to reciprocate along the telescopic direction of the solar photovoltaic member 100. By providing the mounting platform 310, a mounting base can be provided for the solar photovoltaic member 100. By providing the telescopic support assembly 320, the height of the solar photovoltaic member 100 relative to the rotary member 200 can be adjusted to adapt to different application scenarios.

[0078] Preferably, the telescopic direction of the telescopic support assembly 320 can be the up-down direction.

[0079] Further, the light storage device further includes a box body. The box body has an opening. The rotary member 200 is mounted on the box body. The telescopic support assembly 320 is used to drive the solar photovoltaic member 100 to enter and exit the box body through the mounting platform 310.

[0080] In the embodiment, the telescopic support assembly 320 can drive the solar photovoltaic component 100 to extend along the telescopic direction of the telescopic support assembly 320 when the solar photovoltaic component 100 needs to be used, so that the solar photovoltaic component 100 is pushed out of the box and irradiated by sunlight to realize photoelectric conversion. When the solar photovoltaic component 100 needs to be moved to the next working site, the telescopic support assembly 320 is retracted along the telescopic direction of the telescopic support assembly 320, so that the solar photovoltaic component 100 located outside the box returns to the box through the opening. Then the box is used to transport the solar photovoltaic component 100 to the next working site. Obviously, the embodiment avoids moving the solar photovoltaic component 100 in and out of the box, does not need to disassemble and assemble the solar photovoltaic component 100, and solves the problem of low disassembly and assembly efficiency of the medium and large-sized light storage devices in the prior art. The telescopic support assembly 320 serves as a support for the solar photovoltaic component 100, does not need to provide a special mounting bracket 120 for the solar photovoltaic component 100, and does not need to complete the installation of the solar photovoltaic component 100 and the mounting bracket 120 on the ground, thereby solving the problem of large floor space in the prior art that the solar photovoltaic component 100 and the mounting bracket 120 are installed on the ground.

[0081] Preferably, the box is a container.

[0082] Specifically, the container has an opening at the top, the bottom of the telescopic support assembly 320 is installed on the bottom plate of the container through the rotating component 200, and the top of the telescopic support assembly 320 is rotationally connected to the solar photovoltaic component 100 through the mounting platform 310, so as to drive the solar photovoltaic component 100 to move along the up-down direction and make the solar photovoltaic component 100 enter or exit the container through the opening. That is, the telescopic direction of the telescopic support assembly 320 can be the up-down direction.

[0083] Illustratively, the telescopic support assembly 320 includes a first rotary drive and a screw nut structure. The first rotary drive drives the screw to rotate, and the nut drives the solar photovoltaic component 100 to move along the up-down direction under the action of the circumferential limiting piece. It should be noted that the screw nut structure belongs to the prior art and will not be described in detail here.

[0084] Illustratively, the telescopic support assembly 320 includes an electric telescopic rod. The mounting end of the electric telescopic rod is installed on the container through the rotating component 200, and the driving end of the electric telescopic rod is connected to the solar photovoltaic component 100, so as to drive the solar photovoltaic component 100 to move along the up-down direction.

[0085] Exemplarily, the telescopic support assembly 320 comprises a hydraulic cylinder; the mounting end of the hydraulic cylinder is mounted to the container through the rotating part 200, and the driving end of the hydraulic cylinder is connected to the solar photovoltaic part 100 through the connecting rod, for driving the solar photovoltaic part 100 to move along the up-down direction through the connecting rod.

The first telescopic driving member is mounted in the corresponding telescopic cylinder, for driving another telescopic cylinder adjacent thereto to enter or exit the corresponding telescopic cylinder. Specifically, the first multi-stage telescopic assembly comprises two telescopic cylinders and three first telescopic driving members; the first first telescopic driving member is mounted in the container through the rotating platform, the driving end of the first first telescopic driving member is connected to the bottom of the first telescopic cylinder, for driving the first telescopic cylinder to move along the up-down direction. The second first telescopic driving member is mounted in the first telescopic cylinder and connected to the second telescopic cylinder, for driving the second telescopic cylinder to enter or exit the first telescopic cylinder. The third first telescopic driving member is mounted in the second telescopic cylinder and connected to the solar photovoltaic part 100, for driving the solar photovoltaic part 100 to move along the up-down direction.

[0089] Preferably, the first telescopic driving member is a hydraulic cylinder. The hydraulic cylinder has low cost, and is more stable and reliable in heavy load conditions.

[0090] As shown in Figure 6 The second structure: the first multi-stage telescopic structure comprises a plurality of telescopic arms 321, a first telescopic rope wheel 322, and a second telescopic driving member 323. The telescopic arm 321 is a tubular material, and the plurality of telescopic arms 321 are coaxially arranged; the second telescopic driving member 323 is mounted to the rotating platform of the rotating part 200 and connected to the first telescopic arm 321; the fixed pulley of the first telescopic rope wheel 322 is mounted to the top end of the first telescopic arm 321, and one end of the rope row is fixedly connected to the container and the other end is connected to the second telescopic arm 321; the second telescopic driving member 323 drives the first telescopic arm 321 to move upward, and the first telescopic arm 321 drives the second telescopic arm 321 to move upward out of the inner cavity of the first telescopic arm 321 through the first telescopic rope wheel 322, so that the solar photovoltaic part 100 moves out of the container through the opening. By arranging the first telescopic rope wheel 322, one second telescopic driving member 323 can be used to drive the lifting of the plurality of telescopic arms 321, saving cost.

[0091] Further, the first multi-stage telescopic structure further comprises a fixed arm 324, the fixed arm 324 being a pipe; the fixed arm 324 is sleeved outside the first telescopic arm 321, and the second telescopic driving member 323 drives the first telescopic arm 321 to enter or exit the fixed arm 324. The fixed arm 324 plays a role of protecting the second telescopic driving member 323 and the plurality of telescopic arms 321. Specifically, one end of the rope row of the first telescopic wheel rope 322 is connected with the top end of the fixed arm 324, and the other end is connected with the bottom end of the second telescopic arm 321.

[0092] It can be understood that the pipe diameter of the fixed arm 324 is greater than the pipe diameter of the first telescopic arm 321. The plurality of telescopic arms 321 gradually decrease in pipe diameter in the direction from outside to inside. The telescopic arm 321 with a small pipe diameter can freely enter or exit the telescopic arm 321 with a large pipe diameter.

[0093] Further, the first multi-stage telescopic structure further comprises a first retracting wheel rope 325; the fixed pulley of the first retracting wheel rope 325 is installed at the bottom end of the first telescopic arm 321, one end of the rope row of the first retracting wheel rope 325 is connected with the container, and the other end is connected with the second telescopic arm 321. Specifically, one end of the rope row of the first retracting wheel rope 325 is connected with the top end of the fixed arm 324, and the other end is connected with the bottom end of the second telescopic arm 321. When the second telescopic driving member 323 drives the first telescopic arm 321 to descend, the first telescopic arm 321 pulls the second telescopic arm 321 to descend through the rope row of the first retracting wheel rope 325, and the second telescopic arm 321 falls into the first telescopic arm 321, so that the solar photovoltaic component 100 enters the container from the opening. By arranging the first retracting wheel rope 325, it can be ensured that the second telescopic arm 321 can smoothly fall into the first telescopic arm 321, and the falling of the second telescopic arm 321 also plays a certain buffering role.

[0094] Further, the first multi-stage telescopic structure further comprises a mounting base 326; the second telescopic driving member 323 is installed on the rotating platform of the rotating component 200 through the mounting base 326. By arranging the mounting base 326, the mounting stability of the first multi-stage telescopic structure can be improved.

[0095] Preferably, the second telescopic driving member 323 is a hydraulic oil cylinder. The hydraulic oil cylinder has low cost, and is stable and reliable in heavy load bearing.

[0097] Further, the rotating component 200 further comprises a gear set; the rotating driving component drives the rotating platform to rotate around the up-down direction through the gear set.

[0098] Preferably, the rotating driving component comprises a motor or a rotating cylinder.
