Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to an integrated photovoltaic energy storage device. Background Technology

[0002] Currently, there are many ways to fix photovoltaic modules. Some are fixed directly using brackets, and once the photovoltaic modules are assembled, they are basically not moved. Mobile photovoltaic modules have track-type, linkage-type, or roller-type structures. Compared with fixed ones, mobile ones are more convenient, have higher disassembly and assembly efficiency, and are easier to carry.

[0003] However, both fixed and mobile systems have their shortcomings. First, fixed systems are not suitable for scenarios that require frequent relocation. Mobile systems, such as those using tracks, rollers, and linkages, require a high degree of flatness in the ground and are not suitable for complex terrain. In addition, the power generation and energy storage of the two methods cannot be integrated into one, and the electricity generated by the photovoltaic modules cannot be utilized in a timely manner, making them inconvenient to use and transport.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The following is combined Figures 1-5 This invention describes an integrated photovoltaic energy storage device.

[0029] This embodiment provides an integrated photovoltaic energy storage device, including: a housing 1, a flexible support 3, multiple photovoltaic modules 4, and a traction mechanism.

[0030] Among them, a flexible support 3 is connected to one side of the box 1, and the flexible support 3 extends along the first direction; multiple photovoltaic modules 4 are vertically arranged in the box 1 and connected to each other by ropes 5, and the top of the photovoltaic modules 4 can be slidably connected to the flexible support 3; the traction mechanism can drive the multiple photovoltaic modules 4 to move back and forth along the first direction, so as to pull the multiple photovoltaic modules 4 out of the box 1 to unfold or retract the box 1.

[0031] As can be seen from the above scheme, the entire device can be transported as a whole. After arriving at the destination, it can be quickly deployed by a traction mechanism, reducing the complexity and time cost of on-site installation. This utility model vertically stacks the photovoltaic modules 4 in the box 1, reducing the space occupied by the photovoltaic modules 4. Since the photovoltaic modules 4 are stored and transported inside the box 1, the risk of damage during transportation can be reduced. Compared with traditional ground-mounted photovoltaic systems, which are often limited by the flatness of the ground, this device can adapt to uneven or space-constrained sites by adjusting the position of the flexible support 3. During operation, multiple photovoltaic modules 4 are deployed sequentially on the flexible support 3 by a traction mechanism. By arranging the photovoltaic modules 4 in a suspended manner, the photovoltaic modules 4 can be deployed and used on uneven ground, increasing the applicability of the equipment and adapting to more complex terrains. The photovoltaic modules 4 are connected in series and can be deployed and retrieved as a whole by a traction mechanism, making installation convenient and time-saving, suitable for occasions that require frequent relocation and site changes.

[0032] In this embodiment, a pair of flexible support members 3 are provided, and the pair of flexible support members 3 are spaced apart along the second direction, which is perpendicular to the first direction. Sliding members 41 are provided at both ends of the top of the photovoltaic module 4, and the sliding members 41 correspond one-to-one with the flexible support members 3 and are slidably connected.

[0033] Optionally, the sliding member 41 can be a pulley or a lifting ring. For example, the sliding member 41 can be a pulley, with the pulley groove cooperating with the flexible support member 3 to realize the movement of the pulley on the flexible support member 3; or a lifting ring can be used, with the lifting ring sleeved on the flexible support member 3, such as a steel wire rope.

[0034] In this embodiment, an energy storage inverter module 6 is also provided in the housing 1, and each photovoltaic module 4 is electrically connected to the energy storage inverter module 6.

[0035] With this setup, energy storage can be achieved while the photovoltaic module 4 generates electricity. In addition, the inverter can convert DC power into AC power, which can adapt to the needs of more different usage scenarios. It can store energy when there is sufficient sunlight and release energy when there is no sunlight or during peak demand, thus improving energy efficiency.

[0036] like Figures 1-3 As shown, there is a pair of ropes 5, which are spaced apart along the second direction, and the pair of ropes 5 are fixedly connected to the top ends of each photovoltaic module 4. The ropes 5 between two adjacent photovoltaic modules 4 have the same length.

[0037] like Figure 4 As shown, in this embodiment, the photovoltaic module 4 is assembled from a photovoltaic panel 42 and a frame 43. A fixing block 44 is provided on the frame 43, and a sliding member 41 is installed on the fixing block 44. When the photovoltaic module 4 is recycled, since the top two ends of the photovoltaic module 4 are slidably connected to the flexible support member 3, the photovoltaic module 4 can return to a vertical state under its own gravity when the rope 5 is slack, thus improving the recycling efficiency.

[0038] Furthermore, it also includes an angle adjustment rope 7, the first end of which is connected to the rope 5, and the second end of which is connected to the side of the photovoltaic module 4, as shown below. Figure 3 As shown, the second end of the angle adjustment rope 7 is connected to the fixing block 44 of the frame 43 of the photovoltaic module 4. With this configuration, when the traction mechanism pulls the photovoltaic module 4 out of the housing 1 and unfolds it on the flexible support 3, the angle adjustment rope 7 can be used to make each photovoltaic module 4 unfold at a certain angle, which is beneficial to maximize the use of light energy for power generation according to the working environment.

[0039] Optionally, the second end of the angle adjustment rope 7 is connected to the center of the side of the photovoltaic module 4.

[0040] In some embodiments, a position adjustment block 8 is provided on the rope 5 between two adjacent photovoltaic modules 4, and the position adjustment block 8 is connected to the first end of the angle adjustment rope 7. With this configuration, by changing the position of the position adjustment block 8 between the two photovoltaic modules 4, the tilt angle of the suspended photovoltaic modules 4 can be adjusted to better utilize solar energy for power generation according to the environment.

[0041] In other embodiments, a pair of ropes 5 may be fixedly connected to the top and bottom ends of each photovoltaic module 4, respectively, so that the ends of two adjacent photovoltaic modules 4 can be connected by the ropes 5, so that when the photovoltaic module 4 is unfolded, it can be laid horizontally between the box 1 and the fixed support 2.

[0042] In this embodiment, the flexible support 3 is a suspension rope, and steel wire rope is used. A fixed bracket 2 is provided at the end of the flexible support 3 away from the box 1, and a pair of tension wheels 9 are provided at the fixed bracket 2. The tension wheels 9 correspond one-to-one with the flexible support 3, and the end of the flexible support 3 away from the box 1 is wrapped around the tension wheels 9.

[0043] With this setup, during operation, a flexible support 3 is installed between the housing 1 and the fixed bracket 2. Then, multiple photovoltaic modules 4 are sequentially unfolded on the flexible support 3 through a traction mechanism. The tensioning wheel 9 is used to tension the suspension rope, ensuring that the tension of the suspension rope is reliable at all times, so that the photovoltaic modules 4 can slide stably on the suspension rope.

[0044] Alternatively, the support frame can also be a support rod, with both ends of the support rod being detachably connected to the housing 1 and the fixed bracket 2 respectively, thus eliminating the need for tensioning wheels 9.

[0045] In some embodiments, the traction mechanism includes a pull rod 10 and a deployment device. The pull rod 10 is parallel to the second direction, and both ends of the pull rod 10 are connected to the ends of the rope 5 away from the housing 1. The deployment device can act on the pull rod 10 in the first direction to drive the pull rod 10 to move in the first direction to pull the photovoltaic module 4 out of the housing 1 and deploy it in sequence.

[0046] With this configuration, the pull rod 10 is pulled by the unfolding device. Both ends of the pull rod 10 are connected to a pair of ropes 5 respectively, and the pull rod 10 is parallel to the second direction. This allows the photovoltaic module 4 to move stably on a pair of flexible support members 3. During the movement, the top two ends of the photovoltaic module 4 move synchronously and will not tilt. This enables the pull rod 10 to move the ropes 5 on both sides stably and evenly.

[0047] In some embodiments, the deployment device includes a first take-up reel 11 and a traction rope 12, one end of which is vertically connected to the middle of the pull rod 10, and the other end of which is wound around the first take-up reel 11. Figure 1As shown, the first winding wheel 11 is located in the middle of the fixed bracket 2, and the traction rope 12 is vertically connected to the middle of the pull rod 10. By rotating the first winding wheel 11, the traction rope 12 is wound up, which drives the pull rod 10 to approach the fixed bracket 2 in the first direction, so as to pull the photovoltaic module 4 out of the box 1 and unfold it in sequence on the flexible support 3 such as the suspension rope.

[0048] In this embodiment, the traction mechanism also includes a winding device, which is installed in the housing 1. The winding device includes a second winding wheel 13. The end of the rope 5 away from the pull rod 10 is wound around the second winding wheel 13. The second winding wheel 13 can retract the rope 5 by rotating and retract the multiple photovoltaic modules 4 into the housing 1.

[0049] With this setup, when the unfolded photovoltaic module 4 needs to be retracted, the second winding wheel 13 is rotated to wind up the rope 5, causing the photovoltaic module 4 to move closer to the housing 1 along the first direction and be retracted into the housing 1 in sequence.

[0050] like Figure 5 As shown, a second winding wheel 13 can be provided and is located in the middle of the housing 1. A set of guide pulleys is provided on each side of the housing 1, including a first guide wheel 14 and a second guide wheel 15. The first guide wheel 14 is located at the top of each side of the housing 1 and corresponds to a pair of ropes 5. The second guide wheel 15 is located in the middle or lower part of each side of the housing 1. The central axes of the first guide wheel 14 and the second guide wheel 15 are perpendicular to each other. The purpose is to adjust the winding direction of the ropes 5 by 90 degrees, so as to facilitate the winding operation through the second winding wheel 13. The second winding wheel 13 has an independent groove. The ropes 5 on both sides enter the grooves respectively. When the second winding wheel 13 rotates, it can pull the ropes 5 on both sides synchronously, so as to drive the photovoltaic module 4 to move synchronously at both ends.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
