Description

Technical Field

[0001] This utility model relates to the field of battery rack technology, specifically a battery rack for energy storage systems. Background Technology

[0002] Battery racks are standardized racks made of metals such as iron and aluminum, designed to neatly and densely house batteries. User-side energy storage systems typically have limited space, necessitating a high-density, multi-layered battery rack. Because batteries generally require space between adjacent racks to be inserted into the lower rack, the distance between the upper rack and the lower rack needs to be greater than the battery's height. Furthermore, after placement, the batteries' terminals need to be connected, requiring a certain clearance between the battery top and the upper rack for operation. Due to both placement and maintenance considerations, existing battery racks often have large clearances between adjacent layers, resulting in low space utilization. User-side energy storage systems, with their limited space, require a high-density battery rack. Utility Model Content

[0003] The purpose of this invention is to provide a battery rack for an energy storage system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A battery rack for an energy storage system, comprising:

[0006] The main frame is the main structure of the battery rack. The main frame includes two central support rods, which are located on both sides of the main frame. Vertical side support rods are installed at the four top corners of the main frame.

[0007] There are multiple unit frames, which are installed in two vertical columns inside the frame body. The multiple lower rear side baffles in the same column are equidistant from each other. The unit frames are used to support the battery packs. One of the top positions at both ends of the unit frames is rotatably connected to the central support rod on the adjacent side.

[0008] There are two lifting mechanisms, each corresponding to one of the two columns of unit frames. The lifting mechanisms are used to drive the corresponding column of unit frames to deflect.

[0009] Furthermore, the unit frame includes a base support frame, one side of each end of the base support frame is rotatably connected to an adjacent central support rod, a lower rear side baffle is fixedly connected to one side of the base support frame, a front baffle is installed on the other side of the base support frame, and diagonal tie rods are provided at both ends of the base support frame. One end of the diagonal tie rod is fixedly connected to one side of the base support frame, and the other end of the diagonal tie rod is fixedly connected to the top side of the front baffle. The lifting mechanism is used to drive the diagonal tie rods to deflect.

[0010] Furthermore, the lifting mechanism includes two slide rods, which are slidably connected to adjacent side support rods. A lead screw is rotatably connected to the side support rod. Multiple internal thread seats are fixedly connected at equal intervals to one side wall of the slide rod, and the internal thread seats are screwed into the adjacent lead screw. Multiple round rods are fixedly connected at equal intervals to the other side wall of the slide rod. Each of the round rods corresponds one-to-one with a row of multiple unit frames, and the round rods are used to support the diagonal braces on the corresponding unit frames.

[0011] Furthermore, a sprocket is fixedly connected to the top of the lead screw, and a chain is installed between the two sprockets on the same lifting mechanism, and a handwheel is fixedly connected to the top of one lead screw.

[0012] Furthermore, a limit hook is fixedly installed at the other end of the diagonal tie rod, and a roller is rotatably installed at one end of the round rod.

[0013] Furthermore, a limiting groove is provided on the bottom surface of the other end of the diagonal tie rod, and the limiting groove matches the width of the roller.

[0014] Furthermore, a rear panel is fixedly connected between the two limiting grooves, and the rear panel is used to limit the position of the battery.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up unit racks, multiple unit racks in the same row are manually driven to tilt outward through a lifting mechanism, causing the unit racks to tilt upward so that the openings of the unit racks face diagonally upward. This facilitates the tilting insertion of batteries into the unit racks. At the same time, the tilting setting of the unit racks ensures that the top of the battery is fully exposed after insertion, without any obstruction. This makes it convenient for staff to connect, inspect, and adjust the batteries. In other words, the height difference between two adjacent unit rack layers does not need to consider the maintenance space above the battery; only the space for the two unit rack layers to be staggered when tilting is required. This reduces the gap between the upper and lower layers of the unit racks, making the structure more compact and improving space utilization. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a battery rack for an energy storage system includes a frame body 100, unit racks 200, and a lifting mechanism 300. The frame body 100 is the main structure of the battery rack. The frame body 100 includes two central support rods 120, which are located on both sides of the frame body 100. Vertical side support rods 110 are installed at the four corners of the frame body 100. There are multiple unit racks 200, which are divided into two vertical columns and installed in the frame body 100. Multiple lower rear side baffles 220 in the same column are equidistantly arranged. The unit racks 200 are used to support the battery rows. One of the two ends of the unit rack 200 is rotatably connected to the central support rod 120 on the adjacent side. There are two lifting mechanisms 300, which correspond to the two columns of unit racks 200 respectively. The lifting mechanisms 300 are used to drive the corresponding column of unit racks 200 to deflect.

[0026] Specifically, the two rows of unit racks 200 are arranged back to back. During installation, the lifting mechanism 300 manually drives multiple unit racks 200 in the same row to tilt outward, so that the opening of the unit rack 200 faces diagonally upward, making it convenient to insert the battery into the unit rack 200 at an angle. At the same time, the tilting of the unit rack 200 ensures that the top of the battery is fully exposed after it is inserted into the unit rack 200, without any obstruction, which facilitates the connection, inspection and adjustment of the battery by the staff. After the battery installation or inspection is completed, the lifting mechanism 300 drives the unit rack 200 back to the upright position, which facilitates battery inspection and reduces the gap between the upper and lower layers of the unit rack 200, making the structure more compact and improving space utilization.

[0027] Example 1

[0028] like Figures 3-6 As shown, in this embodiment, the unit frame 200 includes a base support frame 210. One side of each end of the base support frame 210 is rotatably connected to the adjacent central support rod 120. A lower rear side baffle 220 is fixedly connected to one side of the base support frame 210, and a front baffle 230 is installed on the other side of the base support frame 210. Diagonal tie rods 240 are provided at both ends of the base support frame 210. One end of the diagonal tie rod 240 is fixedly connected to one side of the base support frame 210, and the other end of the diagonal tie rod 240 is fixedly connected to the top side of the front baffle 230. The lifting mechanism 300 is used to drive the diagonal tie rod 240 to deflect. The lifting mechanism 300 includes two slide rods 340. The slide rods 340 are slidably connected to the adjacent side support rods 110. A lead screw 310 is rotatably connected to the side support rods 110. Multiple internal thread seats 342 are fixedly connected at equal intervals on one side wall of the slide rods 340. The internal thread seats 342 are screwed to the adjacent lead screw 310. Multiple round rods 341 are fixedly connected at equal intervals on the other side wall of the slide rods 340. The multiple round rods 341 correspond one-to-one with multiple unit frames 200 in a row. The round rods 341 are used to support the diagonal braces 240 on the corresponding unit frames 200.

[0029] In this embodiment, the rotation of the lead screw 310 drives the slide bar 340 to move up and down. When the slide bar 340 moves down, the support of the round rod 341 on the inclined tie rod 240 causes the inclined tie rod 240 to deflect downward, thereby causing the unit frame 200 to tilt outward. When the slide bar 340 moves up, it causes the unit frame 200 to return to its upright position. Since the two unit frames 200 at the same height are set back to their respective positions, and the rotation axis between the unit frame 200 and the central support rod 120 is located on one side of the bottom support frame 210, the unit frame 200 is not easy to tilt inward after returning to its upright position. Moreover, when it tilts inward, it will be resisted by the other unit frame 200 at the same height, so that the unit frame 200 can be in a relatively stable state after returning to its upright position, which is convenient for storing batteries.

[0030] like Figures 2-6As shown, in this embodiment, a sprocket 320 is fixedly connected to the top of the lead screw 310, and a chain 330 is installed between the two sprockets 320 on the same lifting mechanism 300. A handwheel is fixedly connected to the top of one lead screw 310. A limit hook 241 is fixedly installed at the other end of the diagonal pull rod 240. A roller 343 is rotatably installed at one end of the round rod 341. A limit groove 242 is opened on the bottom surface of the other end of the diagonal pull rod 240. The width of the limit groove 242 matches that of the roller 343. A rear panel 250 is fixedly connected between the two limit grooves 242. The rear panel 250 is used to limit the position of the battery.

[0031] In practice, the roller 343 rolls on the limiting groove 242, thereby avoiding direct friction between the round rod 341 and the inclined tie rod 240, reducing the difficulty of the slide rod 340 moving upward, and preventing the roller 343 from falling laterally off the inclined tie rod 240 through the setting of the limiting groove 242.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
