[0003] Currently, considering the relatively high humidity conditions in the southern coastal areas, when installing an indoor multifunctional photovoltaic energy storage device, it is usually deployed at a certain height from the ground to optimize space utilization and reduce obstacles. To maximize space efficiency, such devices are often installed in the corner areas of the room. However, when installing a multifunctional photovoltaic energy storage device near a wall corner, a technical challenge will be faced. Due to the narrow gap between the device and the wall corner, it is difficult for installation tools to reach the fastening screws at the predetermined installation points. Even if the tools can contact the screws, the rotational operation is inconvenient due to the limited operating space, which increases the complexity and time consumption of installation and reduces the overall installation efficiency.

[0004] In addition, the traditional installation method also has potential safety hazards. After installation, the fastening screws are directly exposed to the external environment, which is convenient for potential criminals to use simple tools for disassembly, increasing the risk of theft of the energy storage system and seriously threatening the physical safety and operation stability of the system.

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0033] As shown in Figures 1-9 the multifunctional photovoltaic energy storage device, which includes a house wall and an energy storage device body 5. The house wall includes a first wall 1 and a second wall 2. The first wall 1 and the second wall 2 are vertically arranged and form a corner. A positioning and adjusting mechanism is arranged between the energy storage device body 5 and the house wall. A limiting mechanism is arranged between the energy storage device body 5 and the first wall 1. An anti-touch mechanism is arranged on the limiting mechanism. Through the arranged positioning and adjusting mechanism, accurate positioning and rapid adjustment can be achieved, reducing the cumbersome steps in the installation process, significantly improving the installation efficiency, and being able to adjust according to the different distances between the energy storage device body 5 and the second wall 2 to ensure the accuracy and applicability of the installation. Through the arranged limiting mechanism, it is ensured that the energy storage device body 5 is stable and reliable after installation, not easy to shake or fall off. By maintaining a distance from the ground, it effectively prevents the ground moisture from eroding the internal electronic components of the energy storage device body 5. Through the arranged anti-touch mechanism, through the design of the hidden block 27 and the card slot 24, it effectively prevents the illegal contact and theft of the energy storage device body 5 by external personnel;

[0034] As shown in Figures 1-3 、 Figure 5 the positioning and adjusting mechanism includes a fixed sleeve 9 fixedly connected to one end of the energy storage device body 5 close to the second wall 2. A telescopic plate 12 is slidably connected to the inner wall of the fixed sleeve 9. Symmetrically fixed to one end of the telescopic plate 12 close to the second wall 2 are second fixing plates 11. A rotating shaft 16 is fixedly connected between the two groups of second fixing plates 11. Second rollers 10 are rotatably connected to the outer walls of the two rotating shafts 16. Symmetrically fixed to the middle of one end of the energy storage device body 5 close to the first wall 1 are first fixing plates 15. First rollers 7 are rotatably connected between the two groups of first fixing plates 15. The two first rollers 7 and the two second rollers 10 are respectively in contact with the first wall 1 and the second wall 2 and are used for positioning the energy storage device body 5 before installation;

[0035] As shown in Figure 3 、 Figure 4 the positioning and adjusting mechanism further includes threaded rods 13 rotatably connected to both sides of the inner wall of the fixed sleeve 9. The spiral directions of the two threaded rods 13 are the same. Fixedly connected to one end of the two threaded rods 13 away from the telescopic plate 12 are knobs 14. The two threaded rods 13 and the telescopic plate 12 are all threadedly connected. Fixedly connected to the positions of the outer walls of the two threaded rods 13 away from the telescopic plate 12 are sprockets 18. The two sprockets 18 are connected by a chain 17. The synchronous rotation of the two threaded rods 13 makes the telescopic plate 12 move in the direction close to the second wall 2 and adjusts according to the distance between the energy storage device body 5 and the second wall 2 to ensure the positioning effect.

[0036] As shown in Figure 4As shown, the positioning and adjusting mechanism also includes a slide groove 21 opened at one end of the telescopic plate 12 near the chain 17, the inner wall of the slide groove 21 is slidably connected with a slide rod 22, and a first spring 23 is fixedly connected between the slide rod 22 and the slide groove 21, and the end of the slide rod 22 near the chain 17 is horizontally slidably connected with a clamping plate 19, and the clamping plate 19 is clamped in the gap of the chain 17 to complete the fixed limit of the chain 17, and a placement block 20 is fixedly connected to the side of the slide groove 21 at one end of the telescopic plate 12 through a cable, and the placement block 20 is used to be placed in the slide groove 21 to block the slide rod 22. At this time, the clamping plate 19 leaves the gap of the chain 17, and the slide rod 22 is manually pulled in the direction away from the placement block 20, so that the clamping plate 19 is separated from the gap of the chain 17. Subsequently, the placement block 20 is inserted into the slide groove 21 to prevent the slide rod 22 from resetting. Through precise positioning and rapid adjustment, the complicated steps in the installation process are reduced, and the installation efficiency is significantly improved.

[0037] like Figure 1 , Figure 5 , Figure 6 As shown, the limiting mechanism includes a horizontal plate 6 fixedly connected to one end of the first wall 1 close to the energy storage device body 5, and vertical columns 3 are symmetrically fixedly connected to the top of the horizontal plate 6. The two vertical columns 3 are fixedly connected to the first wall 1, and limiting grooves 25 are provided at both ends of the two vertical columns 3. Buffer mechanisms are provided on both sides of the top of the horizontal plate 6 corresponding to the vertical columns 3. The limiting mechanism also includes side panels 4 fixedly connected to both sides of the first fixed plate 15 corresponding to one end of the energy storage device body 5 close to the first wall 1. Two groups of side panels 4 are provided, and the two groups of side panels 4 are fixedly connected to one end close to each other with limiting columns 8 that are adapted to the shape of the limiting grooves 25, and a gap is left between the two groups of side panels 4 and the first wall 1. After the energy storage device body 5 is positioned by the first roller 7 and the second roller 10, the limiting column 8 on the side panel 4 will naturally slide into the limiting groove 25 of the vertical column 3. This design not only ensures the stable installation of the energy storage device body 5, but also keeps it at a certain distance from the ground, effectively preventing the intrusion of ground moisture and protecting the internal electronic components.

[0038] like Figure 8 As shown, the buffer mechanism also includes buffer grooves 32 opened at the top of the horizontal plate 6 and corresponding to the two sides of the vertical column 3, and the inner walls of the two groups of buffer grooves 32 are slidably connected with buffer blocks 26, and buffer springs 33 are fixedly connected between the four groups of buffer blocks 26 and the buffer grooves 32. In addition, during installation, the energy storage device body 5 will be subjected to a vertical downward force, and at this time, the side plate 4 will first contact the buffer block 26, and the elastic force of the buffer spring 33 can absorb and disperse the impact force, further protecting the energy storage device body 5, thereby extending the service life of the energy storage device body 5.

[0039] like Figure 7 , Figure 9As shown, the anti-touch mechanism includes telescopic grooves 28 opened at the bottoms of both ends of the vertical column 3. The inner walls of the two groups of telescopic grooves 28 are both slidably connected with clamping blocks 27. Second springs 29 are fixedly connected between the four groups of clamping blocks 27 and the telescopic grooves 28. Square grooves 31 are opened at the bottoms of the two vertical columns 3. The two square grooves 31 both penetrate through the horizontal plate 6. First ropes 30 are fixedly connected between the two groups of clamping blocks 27. The two first ropes 30 both penetrate through and communicate with the telescopic grooves 28 on both sides. At the bottom of one end of the two side plates 4 close to each other, clamping grooves 24 are opened. After installation, during the downward sliding of the side plate 4, the clamping block 27 will be pushed into the telescopic groove 28. When the side plate 4 reaches the predetermined position, the elastic force of the second spring 29 causes the clamping block 27 to pop out and snap into the clamping groove 24, thereby fixing the side plate 4. Since the clamping block 27 and the clamping groove 24 are hidden inside and are difficult to be touched by external personnel, the safety of the energy storage device body 5 is greatly improved.

[0040] As Figure 8 , Figure 9 shown, the anti-touch mechanism further includes a protective shell 35 fixedly connected to the bottom end of the horizontal plate 6. In the middle of the inner wall of the protective shell 35, a double-shaft motor 37 is fixedly connected. A fixing block 36 is fixedly penetrated on the double-shaft motor 37. Driving shafts 39 are fixedly connected to the driving ends of the fixing block 36. The two driving shafts 39 are both rotatably connected to the protective shell 35. Winding rollers 34 are fixedly connected to the outer walls of the two driving shafts 39 at positions corresponding to the lower sides of the square grooves 31. Second ropes 38 are wound and connected to the outer walls of the two winding rollers 34. The two second ropes 38 and the two first ropes 30 are respectively fixedly connected. When disassembly is required, the double-shaft motor 37 is started through an external control device. The driving shaft 39 drives the winding roller 34 to rotate, winds the second rope 38, and further pulls the clamping block 27 to move inwards through the first rope 30, releasing the fixation of the side plate 4 and realizing rapid disassembly.

[0041] Working principle: First, before use, move the sliding rod 22 away from the placing block 20, and make the clamping plate 19 leave the gap on the chain 17. At this time, insert the placing block 20 into the sliding groove 21 to block the reset of the sliding rod 22. Then rotate the knob 14. Since the two threaded rods 13 are connected by the chain 17 and the sprocket 18, the two threaded rods 13 can rotate synchronously. And through the thread effect of the threaded rod 13, the telescopic plate 12 can move away from or close to the energy storage device body 5, and drive the second fixing plate 11, the rotating shaft 16 and the second roller 10 to move, and make the second roller 10 contact the surface of the second wall 2. After adjustment, pull out the placing block 20 from the sliding groove 21, and through the elastic reset function of the first spring 23, the sliding rod 22 can perform a reset movement, and the clamping plate 19 can slide horizontally on the sliding rod 22. Therefore, the clamping plate 19 can be inserted into the gap on the chain 17 to complete the limit of the chain 17, prevent the threaded rod 13 from deflecting during installation, avoid affecting subsequent positioning and installation. During installation, the second roller 10 contacts the second wall 2 and the first roller 7 contacts the first wall 1 to complete the positioning operation of the energy storage device body 5 and quickly complete the installation, improving the installation efficiency;

[0042] Meanwhile, during the installation process, the limit post 8 is inserted into the limit groove 25, and the energy storage device body 5 is limited through the cooperation of the vertical column 3 and the side plate 4, so that it is stably installed on the house wall. After installation, there is a certain distance from the ground, so that the moisture on the ground can be prevented from entering the energy storage device body 5, thereby protecting the electronic components in the energy storage device body 5. And when the energy storage device body 5 slides down, the side plate 4 will first contact the buffer block 26 and squeeze the buffer spring 33. And through the elastic force of the buffer spring 33, the impact force of the downward movement of the side plate 4 can be buffered, further protecting the energy storage device body 5 and prolonging the service life of the energy storage device body 5;

[0043] When the side plate 4 slides down, it will contact the inclined surface of the clamping block 27 and squeeze it into the telescopic groove 28. When the downward movement of the side plate 4 ends, the clamping block 27 is stuck in the clamping groove 24 through the reset function of the second spring 29 to complete the fixation of the side plate 4. Since the clamping block 27 and the clamping groove 24 cannot be contacted inside, the situation of being stolen can be prevented, improving the overall security. When it needs to be opened, the fixed block 36 is controlled by an external control device to drive the drive shaft 39 to rotate, so that the winding roller 34 can be driven to rotate, and the second rope 38 is wound. At this time, the second rope 38 will pull the middle part of the first rope 30 to move downward, making the first rope 30 present a triangular state with the horizontal line. And the first rope 30 will pull the clamping block 27 to move inward to release the limit of the side plate 4 and complete the disassembly operation.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
