Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a photovoltaic energy storage device. Background Technology

[0002] Currently, medium-sized and larger photovoltaic (PV) energy storage systems primarily utilize shipping containers, which house energy storage units, inverter units, and solar photovoltaic (PV) components. The PV components are typically placed inside the container in the most space-efficient manner. After the PV system is transported to the work site, the PV components are manually removed from the container and then manually installed onto corresponding mounting brackets according to the sunlight angle distribution at the work site, thus assembling the power generation and energy storage system. When it is necessary to move the mobile PV system to the next work site, the PV components must be manually removed from their mounting brackets and reloaded into the container. Clearly, this results in low assembly and disassembly efficiency for medium-sized and larger PV systems. Therefore, improving the assembly and disassembly efficiency of medium-sized and larger PV systems is a pressing issue that the industry urgently needs to address. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0063] The following is combined with Figures 1 to 19 The structure and working principle of the optical storage device, control method, control device and electronic equipment of this utility model are described in detail.

[0064] like Figures 1 to 18 As shown, a specific embodiment of the first aspect of this utility model provides a photovoltaic energy storage device. The photovoltaic energy storage device includes a housing and a photovoltaic energy storage mechanism; the photovoltaic energy storage mechanism includes a solar photovoltaic component 100 and a telescopic component 200.

[0065] The housing has an opening; a telescopic component 200 is installed in the housing and connected to the solar photovoltaic component 100; the telescopic component 200 is used to drive the solar photovoltaic component 100 to move along its own telescopic direction, so that the solar photovoltaic component 100 enters and exits the housing through the opening.

[0066] In this embodiment, a telescopic component 200 is installed in the housing and connected to the solar photovoltaic component 100. When the solar photovoltaic component 100 is needed, the telescopic component 200 can drive the solar photovoltaic component 100 to extend along its own telescopic direction, allowing the solar photovoltaic component 100 to leave the housing through the opening. This allows the solar photovoltaic component 100 to be pushed out of the housing and exposed to sunlight, achieving photoelectric conversion. When it is necessary to move the solar photovoltaic component 100 to the next working location, the telescopic component 200 retracts along its own telescopic direction, allowing the solar photovoltaic component 100 located outside the housing to return to the housing through the opening. The housing is then used to transport the solar photovoltaic component 100 to the next working location. Clearly, this embodiment avoids repeatedly moving the solar photovoltaic component 100 in and out of the housing, eliminating the need for disassembly and assembly of the solar photovoltaic component 100, thus solving the problem of low disassembly and assembly efficiency in existing medium-sized and larger photovoltaic energy storage devices. The telescopic component 200 serves as a support for the solar photovoltaic component 100. It eliminates the need for a dedicated mounting bracket for the solar photovoltaic component 100 and eliminates the need to install the solar photovoltaic component 100 and the mounting bracket on the ground. This solves the problem of large floor space required for the installation of the solar photovoltaic component 100 and the mounting bracket on the ground in the prior art.

[0067] Preferably, the container is a shipping container.

[0068] Specifically, the top of the container has an opening, the bottom of the telescopic component 200 is installed on the bottom plate of the container, and the top of the telescopic component 200 is connected to the solar photovoltaic component 100 to drive the solar photovoltaic component 100 to move in the vertical direction, so that the solar photovoltaic component 100 can enter and exit the container through the opening. In other words, the telescopic component 200 can extend or retract in the vertical direction.

[0069] The structure of the telescopic component 200 is described in detail below.

[0070] It should be noted that the telescopic component 200 can be either manually operated or electrically operated. However, considering the relatively large weight of the solar photovoltaic component 100, it is preferable that the telescopic component 200 is electrically operated.

[0071] For example, the electric telescopic mechanism includes a first rotary drive component and a lead screw and nut structure. The rotary drive component drives the lead screw to rotate, and the nut, under the action of the circumferential limiting component, drives the solar photovoltaic component 100 to move in the vertical direction. It should be noted that the lead screw and nut structure is prior art and will not be described in detail here.

[0072] For example, the electric telescopic mechanism includes a second rotary drive and a rack and pinion transmission structure. The second rotary drive drives the solar photovoltaic component 100 to move vertically via the rack and pinion transmission structure. The rack extends vertically and meshes with the gear. The rack is connected to the solar photovoltaic component 100, and the gear is connected to the second rotary drive; the second rotary drive drives the gear to rotate, thereby causing the rack to move the solar photovoltaic component 100 vertically. It should be noted that the rack and pinion transmission structure is prior art and will not be described in detail here.

[0073] For example, the electrically operated telescopic mechanism includes an electrically operated telescopic pole. The mounting end of the electrically operated telescopic pole is installed on the container, and the driving end of the electrically operated telescopic pole is connected to the solar photovoltaic component 100 for driving the solar photovoltaic component 100 to move in the vertical direction.

[0074] For example, the electric telescopic mechanism includes a hydraulic cylinder; the hydraulic cylinder is installed in the container, and the drive end of the hydraulic cylinder is connected to the solar photovoltaic component 100 via a connecting rod, for driving the solar photovoltaic component 100 to move in the up-down direction via the connecting rod.

[0075] In some embodiments, the telescopic component 200 includes a first multi-stage telescopic assembly; the first multi-stage telescopic assembly can extend or retract step by step along the telescopic direction. By setting the first multi-stage telescopic assembly, the space occupied by the optical storage mechanism in the vertical space inside the container can be reduced, ensuring that the optical storage mechanism can be completely stored inside the container when the telescopic component 200 is retracted.

[0076] The first multi-stage telescopic assembly includes at least the following two structures.

[0077] The first structure: The first multi-stage telescopic assembly includes multiple telescopic cylinders and multiple first telescopic drive components; each first telescopic drive component corresponds one-to-one with a telescopic cylinder. The first telescopic drive component is installed inside the corresponding telescopic cylinder and is used to drive the adjacent telescopic cylinder to move in and out of the corresponding telescopic cylinder. Specifically, the first multi-stage telescopic assembly includes three telescopic cylinders and two first telescopic drive components; the first first telescopic drive component is installed inside the container, and its drive end is connected to the bottom of the first telescopic cylinder, used to drive the first telescopic cylinder to move vertically. The second first telescopic drive component is installed inside the first telescopic cylinder and connected to the second telescopic cylinder, used to drive the second telescopic cylinder to move in and out of the first telescopic cylinder. The third first telescopic drive component is installed inside the second telescopic cylinder and connected to the solar photovoltaic component 100, used to drive the solar photovoltaic component 100 to move vertically.

[0078] like Figure 5 and Figure 6As shown, the second structure includes a first multi-stage telescopic assembly comprising multiple telescopic arms 210, a first extension pulley rope 220, and a second telescopic drive component 230. The telescopic arms 210 are tubular, and multiple telescopic arms 210 are coaxially arranged. The second telescopic drive component 230 is mounted on the container and connected to the first telescopic arm 210. The fixed pulley of the first extension pulley rope 220 is mounted on the top of the first telescopic arm 210, with one end of the rope fixedly connected to the container and the other end connected to the second telescopic arm 210. The second telescopic drive component 230 drives the first telescopic arm 210 upwards. The first telescopic arm 210, through the first extension pulley rope 220, drives the second telescopic arm 210 to move upwards, leaving the inner cavity of the first telescopic arm 210, thus allowing the solar photovoltaic component 100 to exit the container through the opening. By using the first extension pulley rope 220, one second telescopic drive component 230 can be used to drive the lifting of multiple telescopic arms 210, saving costs.

[0079] Furthermore, the first multi-stage telescopic assembly also includes a fixed arm 240, which is a tubular material. The fixed arm 240 is sleeved on the outside of the first telescopic arm 210, and the second telescopic drive member 230 drives the first telescopic arm 210 to move in and out of the fixed arm 240. The fixed arm 240 serves to protect the second telescopic drive member 230 and the multiple telescopic arms 210. Specifically, one end of the rope row of the first extendable wheel rope 220 is connected to the top end of the fixed arm 240, and the other end is connected to the bottom end of the second telescopic arm 210.

[0080] Understandably, the diameter of the fixed arm 240 is larger than the diameter of the first telescopic arm 210. Among the multiple telescopic arms 210, the diameter gradually decreases from the outside in. Between adjacent telescopic arms 210, the smaller-diameter telescopic arm 210 can freely enter and exit the larger-diameter telescopic arm 210.

[0081] Furthermore, the first multi-stage telescopic assembly also includes a first retraction sheave 250; the fixed pulley of the first retraction sheave 250 is installed at the bottom end of the first telescopic arm 210, one end of the rope array of the first retraction sheave 250 is connected to the container, and the other end is connected to the second telescopic arm 210. Specifically, one end of the rope array of the first retraction sheave 250 is connected to the top end of the fixed arm 240, and the other end is connected to the bottom end of the second telescopic arm 210. When the second telescopic drive 230 drives the first telescopic arm 210 to descend, the first telescopic arm 210 pulls the second telescopic arm 210 down through the rope array of the first retraction sheave 250, and the second telescopic arm 210 falls into the first telescopic arm 210, allowing the solar photovoltaic component 100 to enter the container through the opening. By setting the first retraction sheave 250, it can be ensured that the second telescopic arm 210 can smoothly fall into the first telescopic arm 210, and at the same time, it also plays a certain role in buffering the descent of the second telescopic arm 210.

[0082] Furthermore, the first multi-stage telescopic assembly also includes a mounting base 260; the second telescopic drive component 230 is mounted to the container via the mounting base 260. The installation stability of the first multi-stage telescopic assembly can be improved by using the mounting base 260.

[0083] Preferably, the first telescopic drive component is a hydraulic cylinder. Preferably, the second telescopic drive component 230 is also a hydraulic cylinder. Hydraulic cylinders are low in cost and provide more stable and reliable load-bearing capacity under heavy loads.

[0084] The following is a detailed description of the bottom bracket 300.

[0085] like Figure 1 As shown, in some embodiments, the photovoltaic storage mechanism includes a bottom support 300, and the telescopic component 200 is mounted on the container via the bottom support 300, which can increase the contact area between the telescopic component 200 and the container and improve the installation stability of the photovoltaic storage mechanism. Specifically, the mounting base 260 is mounted on the bottom support 300.

[0086] Furthermore, the bottom support 300 has a limiting groove along its length to accommodate the solar photovoltaic panel 110. This improves the installation stability of the solar photovoltaic panel 110 during transportation and reduces the risk of damage due to shaking during transport.

[0087] The structure of the mounting platform 400 and the luffing component 500 will be described in detail below.

[0088] like Figure 1 , Figure 2 , Figure 14 and Figure 15 As shown, in some embodiments, the photovoltaic energy storage mechanism further includes an installation platform 400 and a variable amplitude component 500. The installation platform 400 is mounted on the telescopic component 200 and hinged to the solar photovoltaic component 100. The variable amplitude component 500 is mounted on the housing and connected to the solar photovoltaic component 100; the variable amplitude component 500 is used to drive the solar photovoltaic component 100 to rotate so that the front of the solar photovoltaic component 100 faces the sun. By setting up the installation platform 400, an installation base can be provided for the telescopic component 200, and a hinged base can be provided for the solar photovoltaic component 100. By setting up the variable amplitude component 500 connected to the solar photovoltaic component 100, the angle of the solar photovoltaic component 100 can be adjusted so that the front of the solar photovoltaic component 100 faces the sun, achieving a sun-tracking effect and improving power generation efficiency. In addition, the variable amplitude component 500 can also make the front of the solar photovoltaic component 100 parallel to the axis of the telescopic component 200, which can further reduce the storage volume of the photovoltaic energy storage mechanism when the solar photovoltaic component 100 is not in use, ensuring that the photovoltaic energy storage mechanism can be stored in a standard container.

[0089] like Figure 2 and Figure 15 As shown, the luffing component 500 further includes a connector 550, a first luffing assembly 510, and a second luffing assembly 520. One end of the connector 550 is hinged to the mounting platform 400 via a first hinge shaft 530, and the other end is hinged to the solar photovoltaic component 100 via a second hinge shaft 540; the central axis of the first hinge shaft 530 intersects the central axis of the second hinge shaft 540. The first luffing assembly 510 is connected to the solar photovoltaic component 100 and is used to drive the solar photovoltaic component 100 to rotate via the first hinge shaft 530. The second luffing assembly 520 is connected to the solar photovoltaic component 100 and is used to drive the solar photovoltaic component 100 to rotate via the second hinge shaft 540. By providing a connector 550 with both ends hinged to the mounting platform 400 and the solar photovoltaic component 100 respectively, a rotating mounting foundation can be provided for the solar photovoltaic component. By setting the first amplitude transformer 510 and the second amplitude transformer 520, the solar photovoltaic component 100 can be rotated in two dimensions, which improves the light-tracking ability of the solar photovoltaic component 100 and improves the power generation efficiency.

[0090] Preferably, the axis of the first hinge shaft 530 is perpendicular to the axis of the second hinge shaft 540.

[0091] For example, the first amplitude transformer assembly 510 includes a motor. The motor is mounted on the mounting platform 400, and the drive end of the motor is connected to the first hinge shaft 530 for driving the first hinge shaft 530 to rotate, thereby driving the solar photovoltaic component 100 to rotate through the connector 550.

[0092] For example, the first luffing assembly 510 includes a first luffing telescopic member; the first luffing telescopic member is located on one side of the first hinge shaft 530 along the radial direction of the first hinge shaft 530; one end of the first luffing telescopic member is hinged to the container via a second first hinge shaft 530, and the other end is hinged to the solar photovoltaic component 100 via a third first hinge shaft 530. The first luffing telescopic member drives the solar photovoltaic component 100 to rotate by its own extension and contraction.

[0093] Preferably, the first luffing telescopic component is a hydraulic cylinder or a pneumatic cylinder.

[0094] For example, the second amplitude transformer assembly 520 includes a motor. The motor is mounted on the mounting platform 400, and the drive end of the motor is connected to the second hinge shaft 540 for driving the second hinge shaft 540 to rotate, thereby causing the solar photovoltaic component 100 to rotate.

[0095] For example, the second luffing assembly 520 includes a second luffing telescopic member; the second luffing telescopic member is located on one side of the second hinge shaft 540 along the radial direction of the second hinge shaft 540; one end of the second luffing telescopic member is hinged to the container via a second second hinge shaft 540, and the other end is hinged to the solar photovoltaic component 100 via a third second hinge shaft 540. The second luffing telescopic member drives the solar photovoltaic component 100 to rotate by extending and retracting itself.

[0096] Preferably, the second luffing telescopic component is a hydraulic cylinder or a pneumatic cylinder.

[0097] The structure of the solar photovoltaic component 100 is described in detail below.

[0098] like Figure 1 and Figure 14 As shown, in some embodiments, the solar photovoltaic component 100 includes multiple solar photovoltaic panels 110; adjacent solar photovoltaic panels 110 are connected by a connecting structure, allowing the multiple solar photovoltaic panels 110 to switch between a folded state and an unfolded state. This design not only increases power generation efficiency by increasing the number of solar photovoltaic panels 110, but also reduces the storage volume of the device and the storage space required for the photovoltaic storage device by enabling the multiple solar photovoltaic panels 110 to switch between folded and unfolded states through the connecting structure. This ensures that the solar photovoltaic component 100 will not be unable to fit into or out of a container due to the increased number of solar photovoltaic panels 110, thus reducing transportation costs and handling difficulties.

[0099] It should be noted that the switching between the folded and unfolded states can be done manually or electrically. To save manpower, it is preferable to use an electric method for switching between the folded and unfolded states.

[0100] like Figure 2 and Figure 4 As shown, the solar photovoltaic component 100 further includes multiple solar photovoltaic modules and a photovoltaic mounting frame 120; in the folded state, the multiple solar photovoltaic modules are stacked layer by layer. The solar photovoltaic modules are connected to the photovoltaic mounting frame 120, and the photovoltaic mounting frame 120 is connected to the drive end of the telescopic component 200. The solar photovoltaic panel 110 is mounted on the photovoltaic mounting frame 120. The telescopic component 200 drives the multiple solar photovoltaic modules to reciprocate synchronously in the up-down direction through the photovoltaic mounting frame 120.

[0101] like Figure 10 and Figure 11As shown, in some embodiments, the connection structure includes a sliding connection component 130; adjacent solar photovoltaic modules are slidably engaged via the sliding connection component 130 along the axial direction of the first hinge axis 530. By providing the sliding connection component 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 module in the unfolded state. Providing the sliding connection component 130 can also improve the stability of the solar photovoltaic module 110 during state switching.

[0102] Specifically, the solar photovoltaic module includes a solar photovoltaic panel 110 and a photovoltaic support 111; the solar photovoltaic panel 110 is disposed on the photovoltaic support 111; the photovoltaic supports 111 of two adjacent solar photovoltaic modules are slidably connected along the axial direction of the first hinge axis 530 through a sliding connection component 130.

[0103] like Figure 11 As shown, specifically, the sliding connection assembly 130 includes a protrusion 131 and a groove 132; the protrusion 131 and the groove 132 are respectively formed on two adjacent solar photovoltaic modules along the axial direction of the first hinge axis 530, so that the protrusion 131 and the groove 132 slide in cooperation.

[0104] like Figure 11 As shown, specifically, the photovoltaic support 111 includes two crossbeams 113; the two crossbeams 113 are spaced apart along a direction perpendicular to the axis of the first hinge shaft 530; both ends of the solar photovoltaic panel 110 are connected to the two crossbeams 113 respectively; the upper end of the side of the crossbeam 113 facing the solar photovoltaic panel 110 has one of a groove 132 or a protrusion 131 formed along the axis of the first hinge shaft 530; 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.

[0105] like Figure 15 and Figure 16 As shown, in some other embodiments, the connection structure includes a third hinge shaft 140; the sides of adjacent solar photovoltaic modules are hinged via the third hinge shaft 140, the axis of which is parallel to the axis of the first hinge shaft 530. This design avoids reserving an overlap portion at one end of the solar photovoltaic panel, reducing the space occupied by the photovoltaic energy storage mechanism in terms of height.

[0106] When using a telescopic mechanism to extend and retract solar photovoltaic panels, an overlap is needed at one end of the panel to ensure it is fully extended and not obstructed by the panels above. This overlap increases the space occupied when the panel is vertical and also raises material costs. Therefore, by hinged to the side of adjacent solar photovoltaic modules via a third hinge shaft 140, the overlap at one end of the panel can be avoided, reducing the vertical space required for the photovoltaic energy storage mechanism.

[0107] For example, the connection structure includes multiple third hinge shafts 140, with adjacent third hinge shafts 140 located on the same side of the solar photovoltaic module. Specifically, adjacent third hinge shafts 140 are located on the front or back of the solar photovoltaic module. Taking a solar photovoltaic component 100 comprising three solar photovoltaic modules as an example, for ease of description, the three solar photovoltaic modules are respectively named Module 1, Module 2, and Module 3; in the unfolded state, the three solar photovoltaic modules are arranged sequentially from left to right; after folding Module 2 over Module 1 and folding Module 3 over Module 2, Module 3 is located between Module 1 and Module 2, therefore sufficient space needs to be reserved between Module 1 and Module 2 for placing Module 3.

[0108] For example, the connection structure includes multiple third hinge shafts 140, with adjacent third hinge shafts 140 located on both sides of the solar photovoltaic module. Specifically, adjacent third hinge shafts 140 are located on the front and back of the solar photovoltaic module. Taking a solar photovoltaic component 100 comprising three solar photovoltaic modules as an example, for ease of description, the three solar photovoltaic modules are named Module 1, Module 2, and Module 3, respectively. In the unfolded state, the three solar photovoltaic modules are arranged sequentially from left to right. After folding Module 2 over Module 1 and folding Module 3 over Module 2, the three solar photovoltaic modules are stacked sequentially. That is, sufficient space does not need to be reserved between Module 1 and Module 2 for placing Module 3. In this embodiment, by arranging adjacent third hinge shafts 140 on both sides of the solar photovoltaic module, the space occupied by the photovoltaic energy storage mechanism in terms of height can be further reduced.

[0109] It should be noted that the front of a solar photovoltaic module is the side facing the sunlight, while the back of a solar photovoltaic module is the side away from the front.

[0110] It should be noted that when the solar photovoltaic component 100 is in the unfolded state, the arrangement of the multiple solar photovoltaic panels 110 includes at least two scenarios.

[0111] In the first scenario, when the panels are unfolded, multiple solar photovoltaic panels 110 can be located on the same plane.

[0112] In the second scenario, when the panels are unfolded, multiple solar photovoltaic panels 110 are arranged in a stepped manner. That is, multiple solar photovoltaic panels 110 are not located on the same plane, but rather the planes on which two adjacent solar photovoltaic panels 110 are located are arranged vertically.

[0113] The folding drive component 600 is described in detail below.

[0114] like Figures 7 to 9 As shown, the photovoltaic energy storage mechanism further includes a folding drive component 600; the folding drive component 600 is connected to multiple solar photovoltaic panels 110; the folding drive component 600 is used to drive the multiple solar photovoltaic panels 110 to switch between folded and unfolded states. By setting up the folding drive component 600, manpower can be saved and the switching speed can be improved.

[0115] For example, the folding drive component 600 includes a plurality of first folding telescopic components; all of the plurality of first folding telescopic components are mounted on the mounting platform 400. Each of the plurality of first folding telescopic components corresponds one-to-one with a plurality of solar photovoltaic panels 110, with one end of the first folding telescopic component mounted on the mounting platform 400 and the other end connected to the corresponding solar photovoltaic panel 110. When the plurality of first folding telescopic components extend, the solar photovoltaic component 100 is in an unfolded state. When the plurality of first folding telescopic components retract, the solar photovoltaic component 100 is in a folded state. It is understood that the extension and retraction of the plurality of first folding telescopic components will not cause the solar photovoltaic panels 110 to interfere with each other.

[0116] For example, the folding drive component 600 includes a second multi-stage telescopic assembly; the second multi-stage telescopic assembly is used to extend or shorten step by step along its own telescopic direction; the second multi-stage telescopic assembly is connected to multiple solar photovoltaic panels 110 and is used to drive the multiple solar photovoltaic panels 110 to slide along the telescopic direction, so that the multiple solar photovoltaic panels 110 switch between a folded state and an unfolded state. By setting the second multi-stage telescopic assembly to drive multiple solar photovoltaic panels 110, so that the solar photovoltaic component 100 switches between an unfolded state and a folded state, the storage volume of the photovoltaic energy storage mechanism can be further reduced.

[0117] Preferably, the structure of the second multi-stage telescopic component can be the same as that of the first multi-stage telescopic component.

[0118] like Figures 7 to 9As shown, in some embodiments, the first solar photovoltaic panel 110 is fixedly connected to the telescopic component 200; the second multi-stage telescopic assembly includes a third telescopic drive 610, a second extension wheel rope 620, and a second retraction wheel rope 630. The fixed pulley of the second extension wheel rope 620 is installed at the end of the second solar photovoltaic panel 110 away from the telescopic component 200. One end of the rope of the second extension wheel rope 620 is connected to the first solar photovoltaic panel 110, and the other end is connected to the third solar photovoltaic panel 110. The fixed pulley of the second retraction wheel rope 630 is installed at the end of the second solar photovoltaic panel 110 close to the telescopic component 200. One end of the rope of the second retraction wheel rope 630 is connected to the first solar photovoltaic panel 110, and the other end is connected to the third solar photovoltaic panel 110. The third telescopic drive 610 drives the second solar photovoltaic panel 110 to extend, and the second solar photovoltaic panel 110 drives the third solar photovoltaic panel 110 to extend via the second extension wheel rope 620, thus realizing the deployment of the solar photovoltaic component 100. The third telescopic drive 610 drives the second solar photovoltaic panel 110 to retract, and the second solar photovoltaic panel 110 drives the third solar photovoltaic panel 110 to retract via the second retraction wheel rope 630, thereby realizing the folding of the solar photovoltaic component 100.

[0119] Specifically, one end of the second extending pulley rope 620 is connected to the first solar photovoltaic panel 110, and the other end is connected to the end of the third solar photovoltaic panel 110 near the telescopic component 200. One end of the second retracting pulley rope 630 is connected to the first solar photovoltaic panel 110, and the other end is connected to the end of the third solar photovoltaic panel 110 near the telescopic component 200.

[0120] like Figure 12 and Figure 13As shown, in some embodiments, the folding drive component 600 includes a second extending pulley rope 620, a second retracting pulley rope 630, and an unfolding / retracting drive assembly 640. The fixed pulley of the second extending pulley rope 620 is installed at the end of the solar photovoltaic module away from the telescopic component 200, and the two ends of the rope array of the second extending pulley rope 620 are respectively connected to two adjacent solar photovoltaic modules. The fixed pulley of the second retracting pulley rope 630 is installed at the end of the solar photovoltaic module near the telescopic component 200, and the two ends of the rope array of the second retracting pulley rope 630 are respectively connected to two adjacent solar photovoltaic modules. The unfolding / retracting drive assembly 640 is connected to the solar photovoltaic module and is used to drive multiple solar photovoltaic panels 110 to unfold along the axial direction of the first hinge axis via the second extending pulley rope 620; it is also used to drive multiple solar photovoltaic panels 110 to fold along the axial direction of the first hinge axis 530 via the second retracting pulley rope 630. This design avoids the need for multiple drive structures to drive the solar photovoltaic panels 110 to move along the axial direction of the first hinge axis, thus reducing cost and weight. The movement stability of solar photovoltaic modules can be improved by setting a second extension rope 620 and a second retraction rope 630.

[0121] Preferably, the extension / retraction drive assembly 640 includes a hydraulic cylinder or a pneumatic cylinder.

[0122] like Figure 12 and Figure 13 As shown, preferably, the extension and retraction drive assembly 640 includes a winch drive 641, a winch drum 642, a third extension pulley rope 643, and a third retraction rope array 644. The winch drive 641 is mounted on the mounting platform 400 and connected to the winch drum 642 for driving the winch drum 642 to rotate. The fixed pulley of the third extension pulley rope 643 is mounted on the second solar photovoltaic panel 110, and one end of the rope array of the third extension pulley rope 643 is connected to the end of the second solar photovoltaic panel 110 near the telescopic member 200, while the other end is wound around the winch drum 642. One end of the third retraction rope array 644 is connected to the second solar photovoltaic panel 110, while the other end is wound around the winch drum 642.

[0123] When the winch drive unit 641 drives the winch drum to rotate counterclockwise, the rope of the third extension wheel 643 moves to the left, thereby extending multiple solar photovoltaic panels 110; when the winch drive unit 641 drives the winch drum to rotate clockwise, the third retraction rope 644 moves to the left, thereby retracting multiple solar photovoltaic panels 110.

[0124] like Figure 14 , Figure 15 and Figure 16As shown, in some other embodiments, the folding drive component 600 is hinged to the solar photovoltaic panel 110 to drive the adjacent solar photovoltaic panel 110 to rotate relative to the third hinge axis 140, so that the multiple solar photovoltaic panels 110 switch between an unfolded state and a folded state.

[0125] Specifically, the folding drive component 600 includes at least one linkage structure 650 and at least one first telescopic drive member 660. The linkage structure 650 corresponds to the third hinge shaft 140 and includes a first connecting rod 651, a fourth hinge shaft 652, and a second connecting rod 653. The fourth hinge shaft 652 is arranged parallel to the third hinge shaft 140. The first connecting rod 651 and the second connecting rod 653 are hinged to the fourth hinge shaft 652. The ends of the first connecting rod 651 and the second connecting rod 653 away from the fourth hinge shaft 652 are respectively hinged to the corresponding solar photovoltaic modules. The first telescopic drive member 660 corresponds to the linkage structure 650. One end of the first telescopic drive member 660 is hinged to the solar photovoltaic module, and the other end is rotatably engaged with the corresponding fourth hinge shaft 652. By providing at least one linkage structure 650 and at least one first telescopic drive member 660, a single solar photovoltaic module can be folded and unfolded, making the unfolding and retraction of the solar photovoltaic component 100 more flexible.

[0126] It is understandable that the end of the first link 651 away from the fourth hinge axis 652 rotates axially with the corresponding solar photovoltaic module around the third hinge axis 140, and the end of the second link 653 away from the fourth hinge axis 652 rotates axially with the corresponding solar photovoltaic module around the third hinge axis 140.

[0127] Specifically, the first telescopic drive component 660 includes an electric telescopic rod, a hydraulic cylinder, or a pneumatic cylinder.

[0128] Preferably, the first telescopic drive component 660 is a hydraulic cylinder.

[0129] It should be noted that the correspondence between the connecting rod structure 650 and the third hinge shaft 140 means that the number of connecting rod structures 650 and the third hinge shaft 140 are equal and their positions correspond. Specifically, the third hinge shaft 140 and the corresponding connecting rod structure 650 are both located on the same side of the solar photovoltaic module. Preferably, the third hinge shaft 140 is located between the fourth hinge shaft 652 and the solar photovoltaic module.

[0130] It should be noted that the correspondence between the first telescopic drive member 660 and the connecting rod structure 650 means that the number of the first telescopic drive member 660 and the connecting rod structure 650 are equal.

[0131] like Figure 17 and Figure 18As shown, in some embodiments, the folding drive component 600 includes a first extending rope row 670, a first retracting rope row 680, and a second rotation drive component 690. One end of the first extending rope row 670 passes around the third hinge shaft 140 and is connected to the back of the solar photovoltaic module, or one end is connected to the front of the solar photovoltaic module. One end of the first retracting rope row 680 is connected to the back of the solar photovoltaic module. The second rotation drive component 690 is connected to the other end of the first extending rope row 670 and is used to switch the solar photovoltaic module 100 from a folded state to an unfolded state by pulling the first extending rope row 670. The second rotation drive component 690 is also connected to the other end of the first retracting rope row 680 and is used to switch the solar photovoltaic module 100 from an unfolded state to a folded state by pulling the first retracting rope row 680.

[0132] In this embodiment, the state switching of the solar photovoltaic component 100 is achieved by using a rope array in conjunction with the second rotation drive component 690, which can reduce material costs.

[0133] Taking two solar photovoltaic modules as an example, the second rotary drive 690 is installed on the first solar photovoltaic module, one end of the first extending rope 670 passes around the third hinge shaft 140 and is connected to the back of the second solar photovoltaic module; one end of the first retracting rope 680 is connected to the back of the second solar photovoltaic module; the second rotary drive 690 is connected to the other end of the first extending rope 670, and is used to switch the solar photovoltaic component 100 from a folded state to an unfolded state by pulling the first extending rope 670; the second unfolding drive is also connected to the other end of the first retracting rope 680, and is used to switch the solar photovoltaic component 100 from an unfolded state to a folded state by pulling the first retracting rope 680.

[0134] The second rotary drive unit 690 includes a motor and a winch drum; one end of the first extending rope 670 is wound around the winch drum, and the other end of the first retracting rope 680 is also wound around the winch drum; the motor shaft is connected to the winch drum and is used to drive the winch drum to rotate axially around the third hinge shaft 140. When the motor drives the winch drum to rotate clockwise, the first extending rope 670 is tightened, which can pull the rear solar photovoltaic module from a folded state to an unfolded horizontal state. When the motor drives the winch drum to rotate counterclockwise, the first retracting rope 680 is tightened, which can pull the rear solar photovoltaic module from an unfolded horizontal state back to a folded state.

[0135] In some embodiments, the photovoltaic energy storage mechanism includes two solar photovoltaic components 100, which are symmetrically arranged on the telescopic member 200. By symmetrically installing the solar photovoltaic components 100 on both sides of the telescopic member 200, the power generation efficiency can be further improved.

[0136] The working process of the photovoltaic energy storage device in this embodiment includes the solar photovoltaic component 100 deployment stage and the solar photovoltaic component 100 retraction stage.

[0137] In some embodiments, the operation process of the solar photovoltaic component 100 deployment phase includes:

[0138] The telescopic component 200 drives the solar photovoltaic component 100 to move upward, so that the solar photovoltaic component 100 moves through the opening to the outside of the container;

[0139] The second multi-stage telescopic component extends in stages to drive the multiple solar photovoltaic panels 110 of each solar photovoltaic component 100 to unfold one by one;

[0140] The variable amplitude component 500 operates to drive all the solar photovoltaic panels 110 to face the sun.

[0141] In some embodiments, the process of the solar photovoltaic component 100 recycling phase includes:

[0142] The second multi-stage telescopic component shortens step by step to drive the multiple solar photovoltaic panels 110 of each solar photovoltaic component 100 to retract one by one until the solar photovoltaic component 100 is in a folded state.

[0143] The luffing component 500 actuates to drive each solar photovoltaic component 100 back to its initial position. The initial position can be that the front of the solar photovoltaic panel 110 is parallel to the telescopic component 200;

[0144] The telescopic component 200 retracts to drive the solar photovoltaic component 100 to descend, allowing the solar photovoltaic component 100 to enter the container through the opening, and finally the opening is closed with the container cover.

[0145] A specific embodiment of the second aspect of this utility model provides a control method for a photovoltaic energy storage device. The control method includes: according to an entry / exit control command, controlling a telescopic component 200 to drive a solar photovoltaic component 100 to move along its own telescopic direction, so that the solar photovoltaic component 100 enters and exits the container through an opening.

[0146] It should be noted that the execution subject of the above-mentioned optical storage device control method can be a computer or a controller.

[0147] A specific embodiment of the third aspect of this utility model provides a control device for a photovoltaic energy storage device. The control device includes a control module. The control module is used to control the telescopic component 200 to drive the solar photovoltaic component 100 to move along its own telescopic direction according to an entry / exit control command, so that the solar photovoltaic component 100 enters and exits the container through the opening.
