[0043] Embodiment 1

[0044] See also Figures 1 to 4 As shown, the first embodiment of the present application provides a movable cluster frame 2, including: a cluster frame body 22 and a walking mechanism 21. The cluster frame body 22 includes an outer bracket 221 and a plurality of support plates 222, the outer bracket 221 encloses an inner cavity, each of the support plates 222 is arranged in the inner cavity, the support plate 222 is connected to the outer bracket 221, and a battery pack 24 is detachably connected to the support plate 222. The walking mechanism 21 is arranged at the bottom of the cluster frame body 22. The walking mechanism 21 can walk automatically or passively. For example, the walking mechanism 21 can be a roller arranged at the bottom of the cluster frame body 22. When subjected to external force, the roller will roll and drive the cluster frame body 22 to move. The movable cluster frame 2 of the present application can be set in the cabinet 1 of the energy storage cabinet. During assembly, the battery pack 24 can be installed on the movable cluster frame 2 of the present application outside the cabinet 1, and then the movable cluster frame 2 of the present application and the battery pack 24 as a whole can be driven into the cabinet 1 together. When the battery pack 24 needs to be repaired or replaced, it is only necessary to pull the movable cluster frame 2 and the battery pack 24 as a whole out of the cabinet 1 to replace and repair the battery pack 24 as a whole, saving time and labor costs.

[0045] like Figure 3As shown, the walking mechanism 21 includes two groups of side rollers, which are arranged on both sides of the outer bracket 221. The two groups of side rollers are arranged on both sides of the bottom of the outer bracket 221, and at least two side rollers are arranged on each side, and at least side rollers are arranged at both ends of the bottom of the outer bracket 221 in the width direction.

[0046] In one possible embodiment, Figure 3 As shown, the movable cluster frame 2 includes a support mechanism 23, and the support mechanism 23 is arranged on the outer bracket 221. The support mechanism 23 has a supporting state and a retracted state. In the supporting state, the support mechanism 23 is extended, the lower edge of the support mechanism 23 is lower than the walking mechanism 21, and the support mechanism 23 is directly supported on the supporting surface. In the retracted state, the support mechanism 23 is shortened, and the walking mechanism 21 is supported on the supporting surface. The supporting surface can be the ground, such as the surface of a cement floor. The support mechanism 23 can include a first component 231 and a second component 232. The first component 231 is fixed on one side of the outer bracket 221 connected to the side roller, the first component 231 has an external thread, and the second component 232 has an internal thread. The second component 232 is rotatably threadedly connected to the first component 231, and the overlapping length of the first component 231 and the second component 232 can be adjusted by rotating the second component 232. When the movable cluster frame 2 needs to be fixed on the support surface, the second component 232 can be rotated to lengthen the support mechanism 23. At this time, the length of the support mechanism 23 is greater than the distance between the support surface and the bottom of the movable cluster frame 2. The second component 232 can be supported on the support surface. At this time, the position of the movable cluster frame 2 is fixed and will not move, which facilitates the disassembly and assembly of the battery pack. When the movable cluster frame 2 needs to be moved, the second component 232 can be rotated in the opposite direction to shorten the length of the support mechanism 23. Only the roller is supported on the support surface. At this time, the roller can roll and drive the movable cluster frame 2 to move. The first component 231 can be a threaded column connected to the bottom of the outer bracket 221, and the second component 232 can be a nut threadedly connected to the threaded column. Twisting the nut can adjust the overlap length of the support mechanism 23, so that the support mechanism 23 reaches a supporting state or a retracted state.

[0047] In a possible implementation, a fluid channel is provided inside the support plate 222. The battery pack 24 generates heat during operation, and the battery pack 24 needs to be cooled. In the prior art, a water cooling device is usually provided inside the battery pack 24. The battery pack 24 is a sealed structure. When the water cooling device leaks, it will be difficult to detect, and there is a safety hazard. When it is discovered, the battery pack 24 may be seriously damaged. In the embodiment of the present application, the support plate 222 is used as a water cooling device, and is separately provided with the battery pack 24. The battery pack 24 is a sealed structure. If a leak occurs, water will not enter the battery pack 24, and the battery pack 24 is safer. The support plate 222 has the dual functions of supporting the battery pack 24 and cooling the battery pack 24, which is highly safe, and also saves materials and reduces costs. The battery pack 24 can be connected to the support plate 222 by welding or fasteners.

[0048] The outer bracket 221 is provided with a cooling pipe (not shown), the cooling pipe is connected to the fluid channel, and the cooling pipe is connected to a water cooling unit (not shown). Cooling water of the water cooling unit enters the fluid channel through the cooling channel to cool the battery pack 24.

[0049] The cooling pipe can be pre-buried in the outer bracket 221. The cooling pipe can be fixed outside the outer bracket 221. The inner part of the outer bracket 221 can have a cavity, and the cooling pipe can be pre-buried in the cavity. The outer bracket 221 has a protective effect on the cooling pipe.

[0050] The outer bracket 221 includes two side plates arranged at intervals, the two side plates are arranged at intervals, the support plate 222 is located between the two side plates, and the support plates 222 are respectively connected to the two side plates. There are multiple support plates 222, and the support plates 222 are arranged in sequence along the length of the side plates. A battery pack 24 can be arranged on each support. The cooling pipe includes an inlet pipe and an outlet pipe, and the inlet pipe and the outlet pipe are respectively arranged on the two side plates. The support plate 222 has an inlet and an outlet connected to the fluid channel. The inlet pipe is connected to the inlet, and the outlet pipe is connected to the outlet. The inlet pipe→the inlet→the fluid channel→the outlet→the outlet pipe forms a unidirectional cooling water flow channel.

[0051] In a possible implementation, a water inlet interface connected to the water inlet pipe is provided on one of the side panels. A water outlet interface connected to the water outlet pipe is provided on another of the side panels. The water outlet interface and the water inlet interface are used to connect a water cooling unit, and the water outlet interface is located higher than the water inlet interface. This ensures that the fluid channels in each of the support plates 222 between the water inlet and the water outlet are filled with cooling water, thereby improving the cooling effect of the battery pack 24.

[0052] The support plate 222 is provided with a connection hole (not shown), one end of a fastener passes through the battery pack 24 and is connected to the connection hole, and the other end of the fastener is limited to the battery pack 24. The fastener may be a bolt, the stud of the bolt passes through the battery pack 24 and the connection hole, the nut is threadedly connected to the stud, and the nut of the bolt and the nut are limited between the battery pack 24 and the support plate 222.

[0053] Embodiment 2

[0054] like Figure 1 As shown, the embodiment of the present application also provides a cabinet, including: a cabinet 1 and a movable cluster frame 2 as described above. The cabinet 1 has a cavity. The movable cluster frame 2 can be loaded into or taken out of the cavity. The movable cluster frame 2 has an assembled state and a disassembled state. In the assembled state, the movable cluster frame 2 is accommodated in the cavity. In the disassembled state, the walking mechanism 21 drives the movable cluster frame 2 to drive away from the cabinet 1. The cabinet of the present application can install the battery pack 24 on the movable cluster frame 2 outside the cabinet 1, which is convenient for installing the battery pack 24. During assembly, the movable cluster frame 2 and the battery pack 24 can be directly loaded into the cavity together. When the battery pack 24 needs to be repaired or replaced, it is only necessary to pull the movable cluster frame 2 and the battery pack 24 out of the cabinet 1 to replace and repair the battery pack 24 as a whole, saving time and labor costs. When the cabinet 1 is subjected to a large deformation due to force, it is only necessary to pull out the movable cluster frame 2 and then install the movable cluster frame 2 in a new cabinet 1, reducing the use cost of the cabinet 1.

[0055] like Figure 4 As shown, the cabinet 1 has a bottom plate 11, a top plate 12 and a side plate 13 connecting the bottom plate 11 and the top plate 12, the bottom plate 11, the top plate 12 and the side plate 13 enclose the cavity, a limiting groove 113 is formed on the bottom plate 11, and in the assembled state, the walking mechanism 21 is located in the limiting groove 113. In the assembled state, the walking mechanism 21 can be supported in the limiting groove 113, and the limiting groove 113 can limit the position of the walking mechanism 21, so that the walking mechanism can be as stable as possible in the limiting groove 113, and will not move at least in one direction along the bottom plate 11.

[0056] like Figure 4 As shown, the cabinet 1 includes two side panels 13 arranged at intervals, and the cabinet 1 has a back panel 14, which is respectively connected to the two side panels 13, and the limiting groove 113 extends in a direction perpendicular to the back panel 14. The walking mechanism 21 can move along the limiting groove 113 to drive the movable cluster frame 2 to be accommodated in the cavity or to drive out of the cavity. The limiting groove 113 has a guiding effect on the movable cluster frame 2, so that after entering the limiting groove 113, the movable cluster frame 2 can only move along the direction in which the limiting groove 113 extends, accurately limiting the setting position of the movable cluster frame 2, so that it is convenient for the movable cluster frame 2 to drive into or out of the cavity through the walking mechanism 21.

[0057] Two limiting grooves 113 are formed on the bottom plate 11, and the two groups of side rollers can move along the corresponding limiting grooves 113. The two groups of side rollers are arranged on both sides of the bottom of the movable cluster frame 2 along the length direction, and at least two side rollers are arranged on each side, and at least two side rollers are arranged at both ends of the bottom of the movable cluster frame 2 along the width direction. The movable cluster frame 2 can be supported on the support surface by the two groups of side rollers.

[0058] In one possible embodiment, Figure 4 As shown, the bottom plate 11 includes an outer bottom plate 111 and an inner bottom plate 112, wherein the outer bottom plate 111 is connected to the side plate 13, and the inner bottom plate 112 is connected to the top of the outer bottom plate 111. A limiting groove 113 is formed between one side of the inner bottom plate 112 and the side plate 13, and a stepped limiting groove 113 is formed between the other side of the inner bottom plate 112 and the outer bottom plate 111. In the assembled state, the two groups of side rollers are respectively accommodated in the corresponding limiting grooves 113, and the inner bottom plate 112 is limited between the two groups of side rollers. The distance between the two limiting grooves 113 is the same as the distance between the two groups of side rollers. In the assembled state, the inner bottom plate 112 is limited between the two groups of side rollers.

[0059] The cabinet includes a limiter 3, and the side panels 13 enclose an opening, and the opening is arranged opposite to the back panel 14. The limiter 3 is located on one side of the opening, and the limiter 3 is detachably connected to any one or more of the top panel 12, the bottom panel 11 and the side panel 13, so that the movable cluster frame 2 is limited between the back panel 14 and the limiter 3. The limiter 3 can be connected to any one or more of the top panel 12, the bottom panel 11 and the side panel 13 by a fastener connection or a clamping structure to fix the movable cluster frame 2. In the assembled state, the limiter 3 limits the movable cluster frame 2 from moving out of the opening along the direction in which the limiter groove 113 extends, thereby ensuring the stability of the installation of the movable cluster frame 2 in the cavity. When the battery pack 24 needs to be replaced, the limiter 3 can be removed, and the movable cluster frame 2 can be moved to drive out of the cavity.

[0060] like Figure 2 As shown, the cabinet includes an intermediate fixed beam 4, which is arranged in the cavity. The intermediate fixed beam 4 divides the cavity into a first cavity and a second cavity. The movable cluster frame 2 is located in the first cavity, and the second cavity is provided with a water cooling unit and / or a control component. The intermediate fixed beam 4 plays a role in supporting the top plate 12 and the bottom plate 11, strengthens the structural strength of the cabinet 1, and prevents the cabinet 1 from being deformed by force. The control component may include a PCS, a molded case circuit breaker, etc.

[0061] like Figure 4 As shown, the top plate 12 and the bottom plate 11 are both provided with a slide groove a, and the intermediate fixed beam 4 slides into the cavity along the slide groove a, and the intermediate fixed beam 4 is detachably connected to the cabinet body 1. The intermediate fixed beam 4 and the cabinet body 1 can be connected and fixed by fasteners for easy assembly.

[0062] like Figure 2 As shown, the middle fixed beam 4 includes a plug-in board 41 and a panel 42, the plug-in board 41 is vertically connected to the panel 42, the plug-in board 41 is plugged into the slide slot a, and the panel 42 is exposed from the cabinet 1. The panel 42 and the back plate 14 are limited to the two sides of the movable cluster frame 2 along the width direction, so that the movable cluster frame 2 cannot move out of the opening.

[0063] In one possible embodiment, Figure 2 As shown, the cabinet includes two door bodies 5, both of which are connected to the cabinet 1, one of which is used to open or close the first cavity, and the other of which is used to open or close the second cavity. When the door bodies 5 are in a closed state, the door bodies 5 and the panel 42 are located in the same plane, so that the overall appearance of the cabinet 1 is regular and beautiful.

[0064] The cabinet of the present application modularizes the cavity and proposes a new grouping method for after-sales maintenance, cost reduction, module standardization, and increased strength of the cabinet 1 of the energy storage cabinet, thereby increasing the maintainability of the battery pack 24 and reducing the difficulty of the manufacturing process.
