Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage devices, and particularly to an integrated photovoltaic energy storage device. Background Art

[0002] The photovoltaic energy storage integrated system combines photovoltaic power generation and energy storage technologies, and realizes efficient energy management and stable power supply through the cooperation of multiple devices. Its core devices include power generation and energy storage devices. The power generation device is a photovoltaic module, and the photovoltaic panel in the photovoltaic module is the core of the system's power generation, converting solar energy into electrical energy. The energy storage device is a battery energy storage system, and the energy storage system includes a lithium-ion battery pack (such as a lithium iron phosphate battery), a battery management system, and an energy storage unit. In addition, the integrated photovoltaic energy storage device also needs to be equipped with energy conversion and regulation devices. Most of the energy conversion devices use a battery energy storage converter and a dynamic reactive power compensation device. The battery energy storage converter is responsible for the conversion of direct current and alternating current, and grid-connected or off-grid operation. The dynamic reactive power compensation device is used to adjust the reactive power of the power grid and improve the power quality.

[0003] In the process of using the existing integrated photovoltaic energy storage device outdoors, if it encounters bad weather (such as hail, strong wind or sandstorm weather), when the photovoltaic panel is unfolded, the windward area is large, and the contact range with the falling hail or rain is large, it is easy to be damaged by the impact of foreign objects. Moreover, the strong wind in bad weather will also generate a huge wind pressure on the structure of the photovoltaic panel, which may cause the support to deform or break, the photovoltaic panel to fall off or break, and the overall system to overturn. At the same time, the impurities carried in bad weather usually contaminate the surface of the photovoltaic panel, and the impurities adhered to its surface easily affect the working efficiency of the photovoltaic panel, affecting the normal operation of the whole machine equipment. Therefore, the present invention provides an integrated photovoltaic energy storage device to meet the needs. Summary of the Invention

[0004] In view of the above problems, the present invention provides an integrated photovoltaic energy storage device.

[0005] To achieve the above object, the present invention provides the following technical solution: An integrated photovoltaic energy storage device includes two adjustable-angle photovoltaic panels. A positioning bracket is provided below the two photovoltaic panels, and the positioning bracket can move synchronously as the angle of the photovoltaic panel changes. When the photovoltaic panel is perpendicular to the horizontal plane, the positioning bracket moves to directly below the photovoltaic panel.

[0006] Two lifting guide frames are provided on the positioning bracket. Cleaning soft cushions are provided on one side of the guide frames facing the photovoltaic panels. When the guide frames rise, the cleaning soft cushions can move out above the positioning bracket and clean the surface of the photovoltaic panel along the vertical direction.

[0007] The positioning support is provided with a baffle that can move synchronously with it, and a storage bin is arranged inside the positioning support. Two groups of energy storage batteries electrically connected to the two photovoltaic panels are arranged inside the storage bin, and channels for exposing the energy storage batteries are formed on the sides of the storage bin. When the positioning support moves to directly below the photovoltaic panel, the baffle blocks the channels, and the storage bin is in a closed state.

[0008] Furthermore, first guide rods, second guide rods, and a positioning rod located at the center position on the back of the photovoltaic panel are fixedly installed on the back of the photovoltaic panel. The first guide rods and the second guide rods are respectively located above and below the positioning rod.

[0009] A support seat is installed on the positioning rod, a bidirectional driving screw rod is rotatably installed on the support seat, and the support seat is connected to the storage bin through an extension bracket.

[0010] Furthermore, an upper pushing arm is rotatably connected to the first guide rod. A upper follower seat is rotatably installed at one end of the upper pushing arm away from the first guide rod. The upper follower seats are fixedly connected to a first linkage seat through upper connecting rods. The first linkage seat is located on the side of the upper follower seat away from the photovoltaic panel.

[0011] A lower pushing arm is rotatably connected to the second guide rod. A lower follower seat is rotatably installed at one end of the lower pushing arm away from the second guide rod. The lower follower seats are fixedly connected to a second linkage seat through lower connecting rods. The second linkage seat is located on the side of the lower follower seat facing the photovoltaic panel. The upper follower seats and the lower follower seats are respectively located above and below the bidirectional driving screw rod. The first linkage seat and the second linkage seat are respectively installed on the positive and reverse threads of the bidirectional driving screw rod.

[0012] Furthermore, through holes for accommodating the upper connecting rods to pass through are formed on the second linkage seat, and through holes for accommodating the lower connecting rods to pass through are formed on the first linkage seat. When the first linkage seat and the second linkage seat move, the upper connecting rods and the lower connecting rods slide inside the through holes.

[0013] Furthermore, a linkage gear disc is arranged in the relative space between the two photovoltaic panels. The two ends of the two bidirectional driving screw rods away from the photovoltaic panel are respectively installed on both sides of the linkage gear disc. An electric gear one is meshed and connected to the lower left of the linkage gear disc. As the electric gear one rotates, the linkage gear disc and the two bidirectional driving screw rods rotate synchronously.

[0014] Furthermore, a vertically distributed linkage rack one is meshed and connected to the electric gear one. The linkage rack one is fixed to the positioning support. Two vertically distributed guide rails are arranged outside the storage bin. The positioning support is slidably connected to the guide rails. As the electric gear one rotates, the linkage rack one and the positioning support move synchronously.

[0015] Further, the guiding frame has a U-shaped structure, and the two symmetrical legs of the guiding frame are distributed downward. The cleaning soft cushion layer is arranged on the side of the cross bar of the guiding frame facing the photovoltaic panel, and an inclined slope is formed on the side of the cross bar of the guiding frame away from the photovoltaic panel.

[0016] Further, two vertically distributed guiding sliders are provided on the positioning support, and the two legs of the guiding frame are respectively slidably connected to the two guiding sliders.

[0017] A linkage rack two is provided on one of the legs of the guiding frame, and an electric gear two meshing with the linkage rack two is provided on the positioning support. With the operation of the electric gear two, the linkage rack two and the positioning support move synchronously.

[0018] Further, two groups of positioning columns distributed in a facing direction are provided on the positioning support, and a limiting roller group is provided on the side of each group of positioning columns facing the photovoltaic panel. When the positioning support moves to directly below the photovoltaic panel, the two groups of positioning columns respectively move to the back sides of the two photovoltaic panels, and the limiting roller groups abut against the back sides of the photovoltaic panels.

[0019] Further, a bottom plate is provided at the bottom end of the storage bin, the guiding track is fixed to the bottom plate, and a plurality of installation legs extending downward are provided at the bottom end of the bottom plate.

[0020] In summary, the technical effects and advantages of the present invention are as follows: 1. The present invention can adjust the distribution angle of the photovoltaic panels according to the working cycle. When in bad weather, it can be changed from an inclined state to a vertical state, reducing the exposed area and windward area of the photovoltaic panels, thereby reducing the risk of damage to the photovoltaic panels and having a protective effect on the photovoltaic panels.

[0021] 2. The present invention can move the cleaning soft cushion layer out above the positioning support and clean the surface of the photovoltaic panel along the vertical direction, removing the stains on the surface of the photovoltaic panel caused by bad weather, enabling the photovoltaic power generation work to continue stably and efficiently, ensuring the working efficiency of the photovoltaic panel, and reducing the time required for manual cleaning in bad weather.

[0022] 3. When the photovoltaic panels are retracted to the vertical state, the present invention can synchronously drive the baffle to block the channel of the storage bin, making the storage bin in a closed state. While protecting the photovoltaic panels, it also has a protective effect on the energy storage battery, enabling the entire integrated photovoltaic energy storage device to make a timely protective response according to the changes in the external environment and improving the protective effect of the entire integrated photovoltaic energy storage device in the face of bad weather.

Detailed implementation manners

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Refer to Figure 1 An integrated photovoltaic energy storage device as shown, which includes two adjustable-angle photovoltaic panels 1. A positioning support 2 is provided below the two photovoltaic panels 1. As the angle of the photovoltaic panels 1 changes, the positioning support 2 can move synchronously. During the actual operation of this integrated photovoltaic energy storage device, the two photovoltaic panels 1 are both in an inclined distribution state to receive sunlight and output direct current, which is optimized by the MPPT controller and then connected to the DC bus. Since most of the photovoltaic panels 1 are used outdoors, in case of bad weather (such as hail, strong wind or sandstorm weather), to maintain the stability of the photovoltaic panels 1, the distribution angle of the photovoltaic panels 1 is adjusted to change from the inclined state to the vertical state. When the photovoltaic panels 1 are perpendicular to the horizontal plane, the positioning support 2 moves to directly below the photovoltaic panels 1.

[0036] After the photovoltaic panels 1 are in the vertical state, they are perpendicular to the ground, as shown in Figure 2 shown. The vertically placed photovoltaic panels 1 can avoid the hail or rain falling in bad environments, can reduce the contact range between the photovoltaic panels 1 and the hail or rain in the falling state, and reduce the exposed area. Furthermore, the impact intensity generated by the hail or rain on the photovoltaic panels 1 can be reduced, and the damage probability can be decreased. At the same time, the vertically placed photovoltaic panels 1 can also reduce the windward area, thereby reducing the damage risk of the photovoltaic panels 1. The relatively large impurities carried in bad weather can slide down naturally by gravity, making it difficult to accumulate on the surface of the photovoltaic panels 1, which has a protective effect on the photovoltaic panels 1.

[0037] After the bad weather has passed and the working environment of the photovoltaic panels 1 returns to normal, the distribution angle of the photovoltaic panels 1 can be readjusted to make it in the inclined state to receive sunlight to the maximum extent. Before the photovoltaic panels 1 are adjusted from the vertical state to the inclined state, since the positioning support 2 has moved to directly below the photovoltaic panels 1, and two lifting and lowering guide frames 3 are provided on the positioning support 2, and cleaning soft cushions 4 are provided on the sides of the guide frames 3 facing the photovoltaic panels 1. Therefore, before the photovoltaic panels 1 are adjusted from the vertical state to the inclined state, the guide frames 3 are already aligned with the photovoltaic panels 1, as shown in Figure 6 shown.

[0038] As the guide frames 3 and the cleaning soft cushions 4 move upward, the cleaning soft cushions 4 can be moved out above the positioning support 2 to clean the surface of the photovoltaic panels 1 along the vertical direction. As the guide frames 3 and the cleaning soft cushions 4 reciprocally lift and lower, the cleaning effect on the surface of the photovoltaic panels 1 can be improved.

[0039] During this process, cleaning operations can be simultaneously performed on two photovoltaic panels 1, removing the stains on the surface of the photovoltaic panels 1 caused by bad weather, enabling the photovoltaic power generation work to continue stably and efficiently, ensuring the working efficiency of the photovoltaic panels 1, and reducing the time required for manual cleaning under bad weather.

[0040] Furthermore, as Figure 1 , Figure 2 shown, a baffle 22 that can move synchronously with it is provided on the positioning support 2, and a storage bin 5 is provided inside the positioning support 2. Two groups of energy storage batteries 6 electrically connected to the two photovoltaic panels 1 respectively are provided inside the storage bin 5. The energy storage batteries 6 are connected to the DC bus through a bidirectional DC / DC converter to achieve charge and discharge control. The DC bus is connected to an energy storage inverter, and the energy storage inverter can convert direct current into alternating current for load use or grid connection. When the photovoltaic power generation is insufficient (such as at night or on rainy and cloudy days), the energy storage batteries 6 can convert direct current into alternating current (AC) through the energy storage inverter and directly supply it to the user load. Therefore, the energy storage batteries 6 can supplement the gap and ensure the continuity of power supply.

[0041] As Figure 3 shown, during the operation of the photovoltaic panel 1 and the energy storage battery 6, channels for exposing the energy storage battery 6 are provided on the sides of the storage bin 5. It can ensure the smooth heat dissipation of the energy storage battery 6 and at the same time facilitate the energy storage battery 6 to supply power to external loads. In case of bad weather, to avoid the impact damage of bad weather on the energy storage battery 6 and also avoid a large amount of hail, rain, sand, and other impurities carried under bad weather from entering the inside of the storage bin 5 and damaging the energy storage battery 6. In the present invention, when the positioning support 2 moves to directly below the photovoltaic panel 1, the baffle 22 blocks the channel, and the storage bin 5 is in a closed state.

[0042] Therefore, while protecting the photovoltaic panel 1, the present invention also has a protective effect on the energy storage battery 6, enabling the entire integrated photovoltaic energy storage device to make a protective response in a timely manner according to the changes in the external environment, and improving the protective effect of the entire integrated photovoltaic energy storage device against bad weather.

[0043] Embodiment 2: On the basis of Embodiment 1, the present invention optimizes the angle adjustment method of the photovoltaic panel 1. Specifically, as Figure 4 , Figure 5 shown, first guide rods 11, second guide rods 12, and a positioning rod 13 located at the center position on the back of the photovoltaic panel 1 are fixedly installed on the back of the photovoltaic panel 1. The first guide rods 11 and the second guide rods 12 are respectively located above and below the positioning rod 13. When the angle of the photovoltaic panel 1 is adjusted, it actually rotates around the positioning rod 13.

[0044] As Figure 5As shown, a support base 131 is installed on the positioning rod 13. A bidirectional driving screw 14 is rotatably installed on each support base 131, and the support base 131 is connected to the storage bin 5 through an extension bracket 132. The extension bracket 132 can maintain the stability of the support base 131 and the bidirectional driving screw 14 connected thereto, and thus can maintain the stability of the positioning rod 13 and the photovoltaic panel 1.

[0045] A upper push arm 111 is rotatably connected to the first guide rod 11. A upper follower seat 112 is rotatably installed at one end of the upper push arm 111 away from the first guide rod 11. Each upper follower seat 112 is fixedly connected to a first linkage seat 114 through an upper connecting rod 113. The first linkage seat 114 is located on the side of the upper follower seat 112 away from the photovoltaic panel 1.

[0046] A lower push arm 121 is rotatably connected to the second guide rod 12. A lower follower seat 122 is rotatably installed at one end of the lower push arm 121 away from the second guide rod 12. The lower follower seat 122 is fixedly connected to a second linkage seat 124 through a lower connecting rod 123. The second linkage seat 124 is located on the side of the lower follower seat 122 facing the photovoltaic panel 1. The upper follower seat 112 and the lower follower seat 122 are respectively located above and below the bidirectional driving screw 14. The first linkage seat 114 and the second linkage seat 124 are respectively installed on the positive and reverse threads of the bidirectional driving screw 14.

[0047] As Figure 8 、 Figure 9 shown, when the bidirectional driving screw 14 rotates, the first linkage seat 114 and the second linkage seat 124 located on the positive and reverse threads of its surface can move in opposite directions. Under the connection action of the upper connecting rod 113 and the lower connecting rod 123, one of the upper follower seat 112 and the lower follower seat 122 can move away from the photovoltaic panel 1 and the other can move closer to the photovoltaic panel 1, thereby making one of the upper push arm 111 and the lower push arm 121 move away from the photovoltaic panel 1 and the other move closer to the photovoltaic panel 1. Under the connection action of the first guide rod 11 and the second guide rod 12, the purpose of adjusting the angle of the photovoltaic panel 1 can be achieved.

[0048] Specifically, as Figure 9 shown, taking the movement process of the photovoltaic panel 1 rotating from the vertical state to the inclined state as an example, when the bidirectional driving screw 14 rotates counterclockwise, the second linkage seat 124, the lower connecting rod 123 and the lower follower seat 122 can move closer to the photovoltaic panel 1, and the first linkage seat 114, the upper connecting rod 113 and the upper follower seat 112 can move away from the photovoltaic panel 1. The lower push arm 121 pushes the second guide rod 12 to extend, and the upper push arm 111 pulls the first guide rod 11 to retract, so that the positioning rod 13 of the photovoltaic panel 1 rotates to the inclined state.

[0049] Further, to maintain the stability of the first linkage seat 114 and the second linkage seat 124 during movement and prevent them from shifting or shaking, in the present invention, the second linkage seat 124 is provided with a through hole for the upper connecting rod 113 to pass through, and the first linkage seat 114 is provided with a through hole for the lower connecting rod 123 to pass through. When the first linkage seat 114 and the second linkage seat 124 move, the upper connecting rod 113 and the lower connecting rod 123 both slide within the through holes. Refer to Figure 9 as shown.

[0050] As Figure 6 、 Figure 7 shown, a linkage gear disk 15 is provided within the relative space between the two photovoltaic panels 1. The two ends of the two bidirectional drive screws 14 away from the photovoltaic panels 1 are respectively installed on both sides of the linkage gear disk 15. The movement of the linkage gear disk 15 can cause the two bidirectional drive screws 14 to rotate synchronously, thereby enabling the photovoltaic panels 1 to adjust the angle and switch back and forth between the vertical state and the inclined state. To provide power to the linkage gear disk 15, an electric gear one 16 is meshed and connected diagonally below the linkage gear disk 15. As the electric gear one 16 operates, the linkage gear disk 15 and the two bidirectional drive screws 14 rotate synchronously to achieve the purpose of switching the angle of the photovoltaic panels 1.

[0051] Embodiment 3: On the basis of Embodiment 1 and Embodiment 2, as Figure 6 、 Figure 7 shown, a vertically distributed linkage rack one 21 is meshed and connected to the electric gear one 16. The linkage rack one 21 is fixed to the positioning support 2. Two vertically distributed guiding tracks 51 are provided outside the storage bin 5. The positioning support 2 is slidably connected to the guiding tracks 51. During the process of the linkage gear disk 15 driving the two bidirectional drive screws 14 to rotate, as the electric gear one 16 operates, the linkage rack one 21 and the positioning support 2 move synchronously until the positioning support 2 approaches or moves away from the photovoltaic panels 1.

[0052] Therefore, when the photovoltaic panels 1 are retracted to the vertical state or rotated to the working state, the positioning support 2 can quickly respond to adapt to different states of the photovoltaic panels 1. The entire process does not require additional manual adjustment, improving the portability during the adjustment of the positioning support 2.

[0053] As Figure 6As shown in the figure, during the cleaning operation of the photovoltaic panel 1, the guiding frame 3 and the cleaning soft cushion layer 4 need to move upward first and then downward. To prevent the impurities accumulated above the cleaning soft cushion layer 4 from adhering to the surface of the photovoltaic panel 1 again during the downward movement of the guiding frame 3 during the upward movement, in the present invention, the guiding frame 3 has a U-shaped structure, and the two symmetrical legs of the guiding frame 3 are distributed downward. The cleaning soft cushion layer 4 is arranged on the side of the crossbar of the guiding frame 3 facing the photovoltaic panel 1, and an inclined slope is formed on the side of the crossbar of the guiding frame 3 away from the photovoltaic panel 1. The impurities pushed away by the cleaning soft cushion layer 4 during the upward movement can slide down along the inclined slope, thereby effectively preventing the impurities accumulated above the cleaning soft cushion layer 4 from adhering to the surface of the photovoltaic panel 1 again and ensuring the cleaning effect of the photovoltaic panel 1.

[0054] In the present invention, the cleaning soft cushion layer 4 is made of sponge or elastic rubber structure. When cleaning the surface of the photovoltaic panel 1, it can generate flexible friction with it to achieve the effect of pushing away the impurities on its surface.

[0055] As Figure 6 shown in the figure, to improve the stability of the guiding frame 3, two vertically distributed guiding sliders 24 are arranged on the positioning support 2, and the two legs of the guiding frame 3 are respectively slidably connected to the two guiding sliders 24. A linkage rack two 31 is arranged on one of the legs of the guiding frame 3, and an electric gear two 23 meshing with the linkage rack two 31 is arranged on the positioning support 2. The electric gear two 23 provides the movement power. As the electric gear two 23 rotates, the linkage rack two 31 and the positioning support 2 move synchronously to drive the guiding frame 3 and the cleaning soft cushion layer 4 to move up and down.

[0056] Example 4: As Figure 1 shown in the figure, during the process of adjusting the photovoltaic panel 1 to the vertical state, to improve the accuracy when the positioning support 2 is docked with the bottom of the photovoltaic panel 1, two groups of positioning columns 25 distributed in a facing direction are arranged on the positioning support 2, and a limit roller group 26 is arranged on the side of each group of positioning columns 25 facing the photovoltaic panel 1. When the positioning support 2 moves to directly below the photovoltaic panel 1, the two groups of positioning columns 25 respectively move to the back of the two photovoltaic panels 1, and the limit roller group 26 abuts against the back of the photovoltaic panel 1.

[0057] The combined setting of the two groups of positioning columns 25 and the limit roller group 26 can maintain the stability of the photovoltaic panel 1 when the positioning support 2 moves below the photovoltaic panel 1, and further ensure the stability of the photovoltaic panel 1 when the guiding frame 3 and the cleaning soft cushion layer 4 perform the cleaning operation on the photovoltaic panel 1.

[0058] During the actual working process of the present invention, a bottom plate 7 is arranged at the bottom end of the storage bin 5, the guiding track 51 is fixed to the bottom plate 7, and a plurality of installation feet 8 extending downward are arranged at the bottom end of the bottom plate 7. Refer to Figure 2As shown, the installation feet 8 are arranged such that there is a certain distance between the storage bin 5 and the internal energy storage battery 6 and the ground, which not only ensures the heat dissipation effect of the energy storage battery 6 but also facilitates the staff to view and repair the energy storage battery 6.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
