Description

Technical Field

[0001] This utility model belongs to the field of energy storage power station technology, specifically relating to a liquid-cooled energy storage power station. Background Technology

[0002] Energy storage power stations are devices that use electrochemical batteries or electromagnetic energy storage media to cyclically store, convert, and release electrical energy. Common energy storage power stations mainly consist of battery packs, inverters, control systems, and cabinets. Since energy storage power stations mainly use battery packs to store and convert electrical energy, and battery packs release a lot of heat during charging and discharging, energy storage power stations usually need to be equipped with corresponding cooling and heat dissipation systems to ensure the stable operation of the energy storage power station.

[0003] Liquid-cooled energy storage power stations are a type of energy storage power station that uses the circulation of heat exchange fluid to remove heat from the energy storage power station. Liquid-cooled energy storage power stations are equipped with liquid-cooled flow channels, in which heat exchange fluid circulates to remove the heat released by the batteries in the energy storage power station.

[0004] In existing liquid-cooled energy storage power stations, battery packs are mainly assembled and fixed by internal battery pack brackets. Due to the high assembly density of battery packs in liquid-cooled energy storage power stations, the gaps between each battery pack are small. This results in limited space for disassembly, assembly, and maintenance of the battery packs, making the assembly and maintenance process more difficult and increasing the maintenance complexity of liquid-cooled energy storage power stations.

[0005] Therefore, in order to address the aforementioned technical issues, it is necessary to provide a liquid-cooled energy storage power station.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0008] To achieve the above objectives, a specific embodiment of this utility model provides a liquid-cooled energy storage power station, including: a cabinet, multiple sets of convenient assembly and fixing mechanisms, and multiple sets of auxiliary moving mechanisms.

[0009] Multiple sets of the aforementioned convenient assembly and fixing mechanisms are fixedly assembled inside the cabinet. Each convenient assembly and fixing mechanism includes a battery pack assembly rack. The battery pack assembly rack is fixedly assembled inside the cabinet. Multiple sets of evenly distributed L-shaped assembly racks are fixedly assembled inside the battery pack assembly racks. Each set of L-shaped assembly racks is fixedly connected to a fixing frame. Multiple sets of evenly distributed guide rollers are rotatably assembled inside the fixing frame. Battery packs are evenly distributed above the multiple sets of guide rollers. Clamping and limiting pads are attached to the side of each set of L-shaped assembly racks that is close to the battery pack.

[0010] Multiple sets of the auxiliary moving mechanisms are fixedly assembled on both sides of multiple battery packs. Each auxiliary moving mechanism includes a moving lead screw, which is rotatably assembled on the side wall of the battery pack assembly frame. A pair of threaded sliders are threadedly connected to the outer side of the moving lead screw, and a clamping limit plate is fixedly assembled on the side of each pair of threaded sliders close to the battery pack.

[0011] In one or more embodiments of this utility model, the battery pack assembly frame consists of multiple sets of uprights, crossbars, and reinforcing bars. The multiple sets of crossbars are arranged at the upper and lower ends of the uprights, and the multiple sets of reinforcing bars are fixedly assembled between the multiple sets of crossbars.

[0012] In one or more embodiments of this utility model, a fixed base plate is fixedly connected to the bottom of each set of uprights. The battery pack assembly rack is fixedly assembled inside the cabinet by assembling and fixing the fixed base plate.

[0013] In one or more embodiments of this utility model, a limiting baffle is fixedly connected to one end of each of the multiple sets of L-shaped assembly racks located inside the cabinet. The limiting baffle is used to assemble and fix the guide rod. A guide rod is inserted into the limiting baffle.

[0014] In one or more embodiments of this utility model, the guide rod passes through the limiting baffle, and both sides of the guide rod outside the limiting baffle are threaded with fixing nuts. The fixing nuts serve to assemble and fix the guide rod.

[0015] In one or more embodiments of this utility model, a limiting slide rod is slidably mounted inside the guide rod. The limiting slide rod supports and fixes the limiting end, and by sliding the limiting slide rod inside the guide rod, the limiting end serves to limit the assembly of the battery pack. The end of the limiting slide rod closest to the battery pack is fixedly connected to the limiting end. The limiting end limits the assembly of the battery pack.

[0016] In one or more embodiments of this utility model, a return spring is fitted on the outer side of the limiting slide rod, and the return spring is arranged between the limiting slide rod and the guide rod. By contracting and resetting the return spring, the limiting end is supported and reset, thereby improving the effect of the limiting end in buffering and limiting the battery pack.

[0017] In one or more embodiments of this utility model, a buffer airbag is fixedly connected to the side of the limiting baffle close to the battery pack. The buffer airbag provides auxiliary limiting for the battery pack. A venting pipe connects the buffer airbag and the clamping limiting pad. The venting pipe facilitates the flow of gas from the buffer airbag into the clamping limiting pad under external force, thereby improving the stability of the L-shaped mounting bracket in assembling and fixing the battery pack through the expansion of the clamping limiting pad.

[0018] In one or more embodiments of this utility model, sliding guide rods are evenly distributed on both the upper and lower sides of the movable lead screw.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments 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, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figures 1 to 8 As shown, a liquid-cooled energy storage power station according to one embodiment of the present invention includes: a cabinet 1, multiple sets of convenient assembly and fixing mechanisms 2, and multiple sets of auxiliary moving mechanisms 3.

[0034] like Figure 1As shown, multiple sets of convenient assembly and fixing mechanisms 2 are fixedly assembled inside the cabinet 1. The convenient assembly and fixing mechanism 2 includes a battery pack assembly rack 201, which is fixedly assembled inside the cabinet 1. Multiple battery packs 205 are assembled and fixed through the battery pack assembly rack 201.

[0035] like Figures 1 to 2 As shown, the battery pack assembly frame 201 consists of multiple sets of uprights 2011, crossbars 2012, and reinforcing bars 2013. The multiple sets of crossbars 2012 are arranged at the upper and lower ends of the uprights 2011, and the multiple sets of reinforcing bars 2013 are fixedly assembled between the multiple sets of crossbars 2012.

[0036] like Figures 1 to 2 As shown, each of the multiple uprights 2011 has a fixed base plate 207 fixedly connected to its bottom. The battery pack assembly frame 201 is fixedly assembled into the cabinet 1 by assembling and fixing the fixed base plate 207.

[0037] like Figures 2 to 3 As shown, multiple sets of evenly distributed L-shaped assembly frames 202 are fixedly assembled inside the battery pack assembly frame 201. The multiple sets of L-shaped assembly frames 202 support and limit the multiple battery packs 205.

[0038] like Figures 2 to 3 As shown, each of the multiple L-shaped assembly frames 202 is fixedly connected to a fixing frame 203. The fixing frame 203 serves to limit the assembly of the multiple guide rollers 204.

[0039] like Figures 2 to 3 As shown, multiple sets of evenly distributed guide rollers 204 are rotatably mounted inside the fixed frame 203. These guide rollers 204 support and limit the battery pack 205. Simultaneously, the rolling motion of the guide rollers 204 improves the smoothness of assembling and disassembling the battery pack 205.

[0040] like Figure 1 As shown, battery packs 205 are evenly distributed above multiple sets of guide rollers 204.

[0041] like Figures 2 to 3 As shown, each of the multiple L-shaped assembly racks 202 has a clamping and positioning pad 206 attached to the side of the battery pack 205. The clamping and positioning pad 206 assists in clamping the battery pack 205 supported on the L-shaped assembly rack 202.

[0042] like Figures 2 to 6 As shown, each of the multiple L-shaped assembly racks 202 located inside the cabinet 1 has a limiting baffle 208 fixedly connected to one end. The guide rod 209 is assembled and fixed by the limiting baffle 208.

[0043] like Figures 2 to 6As shown, a guide rod 209 is inserted into the limiting baffle 208, and the guide rod 209 passes through the limiting baffle 208. The guide rod 209 serves to limit the assembly and guide the sliding of the limiting slide rod 211.

[0044] like Figures 2 to 6 As shown, both sides of the guide rod 209 outside the limiting baffle 208 are threaded with fixing nuts 210. The fixing nuts 210 serve to assemble and fix the guide rod 209.

[0045] like Figures 2 to 6 As shown, a limiting slide rod 211 is slidably mounted inside the guide rod 209. The limiting slide rod 211 supports and fixes the limiting end 212, and the limiting end 212 is positioned to limit the assembly of the battery pack 205 by sliding the limiting slide rod 211 inside the guide rod 209.

[0046] like Figures 2 to 6 As shown, a limiting end 212 is fixedly connected to one end of the limiting slide bar 211 that is close to the battery pack 205. The limiting end 212 is used to limit the assembly of the battery pack 205.

[0047] like Figures 2 to 6 As shown, a return spring 213 is fitted on the outer side of the limiting slide bar 211, and the return spring 213 is arranged between the limiting slide bar 211 and the guide rod 209. The contraction and reset of the return spring 213 supports and resets the limiting end 212, thereby improving the buffering and limiting effect of the limiting end 212 on the battery pack 205.

[0048] like Figures 5 to 6 As shown, a buffer airbag 214 is fixedly connected to the side of the limiting baffle 208 close to the battery pack 205. The buffer airbag 214 serves to assist in limiting the battery pack 205.

[0049] like Figures 5 to 6 As shown, a venting tube 215 connects the buffer airbag 214 and the clamping and limiting pad 206. The venting tube 215 connects the buffer airbag 214 and the clamping and limiting pad 206, allowing the gas inside the buffer airbag 214 to be transported to the clamping and limiting pad 206 under external force. This, in turn, improves the stability of the L-shaped mounting bracket 202 in assembling and fixing the battery pack 205 by expanding the clamping and limiting pad 206.

[0050] like Figures 2 to 4 As shown, multiple sets of auxiliary moving mechanisms 3 are fixedly assembled on both sides of multiple battery packs 205. Each auxiliary moving mechanism 3 includes a moving lead screw 301, which is rotatably mounted on the side wall of the battery pack assembly frame 201. The moving lead screw 301 serves to limit the assembly and control the movement of the threaded slider 302.

[0051] like Figures 2 to 4 As shown, a pair of threaded sliders 302 are threadedly connected to the outer side of the movable lead screw 301. The threaded sliders 302 serve to assemble, fix, and control the movement of the clamping and limiting plate 303.

[0052] like Figures 2 to 4 As shown, a pair of threaded sliders 302 are each fixedly fitted with a clamping limiting plate 303 on the side close to the battery pack 205. The clamping limiting plate 303 is used to assist in clamping and moving the battery pack 205 assembled on the L-shaped assembly frame 202.

[0053] Specifically, the clamping limit plate 303 can be made to contact the side of the battery pack 205 by attaching an elastic pad to the clamping limit plate 303.

[0054] like Figures 2 to 4 As shown, sliding guide rods 304 are evenly distributed on both the upper and lower sides of the movable lead screw 301. The sliding guide rods 304 pass through the threaded slider 302, and both ends of the sliding guide rods 304 are fixedly connected to the battery pack assembly frame 201. The sliding guide rods 304 serve to guide the threaded slider 302.

[0055] like Figures 2 to 4 As shown, a rotating end 305 is fixedly connected to one end of the movable lead screw 301 located outside the battery pack assembly frame 201. The rotation of the movable lead screw 301 is controlled by controlling the rotation of the rotating end 305.

[0056] In practical use, when assembling the battery pack 205, the battery pack 205 is placed on a pair of L-shaped mounting brackets 202. An elastic pad is attached to the surface of the clamping limiting plate 303 to make it contact the side wall of the battery pack 205. Then, the rotating end 305 is controlled to rotate the moving lead screw 301. The threaded slider 302 moves with the rotation of the moving lead screw 301 under the action of its internal and external threads. The movement of the clamping limiting plate 303, driven by the threaded slider 302, clamps the battery pack 205 and moves it into the cabinet 1.

[0057] During the assembly of battery pack 205, multiple sets of guide rollers 204 support and assist in its movement. The limiting end 212 and the buffer airbag 214 limit the assembly position of battery pack 205. When battery pack 205 compresses the buffer airbag 214 during movement, the air inside the buffer airbag 214 is transported along the air pipe 215 to the clamping limiting pad 206. The expansion of the clamping limiting pad 206 improves the stability of the L-shaped assembly frame 202 in clamping battery pack 205.

[0058] When it is necessary to disassemble and repair the battery pack 205, the battery pack 205 can be disassembled and repaired by rotating the rotating end 305 in the opposite direction, which simplifies the disassembly and assembly process of the battery pack 205 and improves the convenience of disassembly, assembly and maintenance of the energy storage power station.

[0059] 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.

[0060] 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.
