Description

Technical Field

[0001] The present invention relates to the technical field of battery energy storage equipment, and in particular to a retractable energy storage device. Background Art

[0002] A battery energy storage device is a device that converts electrical energy into chemical energy and stores it in a battery so that it can be converted into electrical energy and output when needed. That is, the battery module contained in the battery energy storage device stores electrical energy and outputs it when needed, thereby performing a cyclic operation.

[0003] At present, battery energy storage equipment mainly uses energy storage containers for energy storage. The battery modules are assembled into a single battery pack, and the battery packs are arranged in an array and assembled on a metal frame, thereby stacking the battery modules in sequence to store them. At the same time, due to the large weight and volume of the battery modules, it is necessary to use external equipment (for example, a lifter) to lift and lower the battery during storage. However, battery energy storage equipment stored in this way has many inconveniences in the subsequent maintenance process. Specifically, if it is necessary to inspect or replace the battery modules in the battery cluster, it is necessary to use external equipment to move out all the battery modules stored above the battery module in the battery energy storage equipment in sequence before the battery module can be inspected or replaced, which leads to inconvenience in maintenance.

[0036] It should be noted that, in this application, "lateral" refers to the Figure 1 The X-axis is the direction of the vertical axis. Figure 1 The Y-axis is shown in the vertical direction. Figure 1 The direction of the Z axis shown in .

[0037] Ginseng Figures 1 to 12 As shown, the present invention shows a specific implementation of a retractable energy storage device (hereinafter referred to as "device"), which is used for retracting and releasing the energy storage box 13 in the energy storage compartment 10, thereby facilitating the subsequent maintenance or replacement of the battery module 131.

[0038] Ginseng Figures 1 to 8As shown, the device 100 includes: at least one energy storage cabin 10 with an opening 11 and a retracting mechanism 20 arranged on the side of the opening 11 of the energy storage cabin 10. The energy storage cabin 10 includes: a cabin body 12 with a accommodating space 30 and at least one energy storage box 13 arranged in the accommodating space 30, the inner side wall of the cabin body 12 protrudes toward the accommodating space 30 to form at least one set of track beams 14, and the energy storage box 13 is movably placed on the track beams 14 through a moving member 15. The retracting mechanism 20 includes: at least one set of guide beams 21 arranged along the extension direction of the single set of track beams 14 toward the opening 11 and a fixing frame 22 fixedly arranged on the side of the opening 11 of the energy storage cabin 10 to support the guide beams 21, and the single set of track beams 14 and the single set of guide beams 21 are connected to form a track (not marked) for the energy storage box 13 to move back and forth. Based on this, in actual application scenarios, the energy storage box 13 can be driven by a driving member (not shown, for example, an electric hoist, etc.) or manually to move back and forth on the track formed by the docking of the track beam 14 and the guide beam 21, so that the energy storage box 13 can be movably accommodated in the energy storage cabin 10, so as to facilitate the inspection or replacement of the battery module 131 stored in the energy storage box 13, and finally solve the problem of inconvenience in battery module maintenance due to the limitations of the internal structure of the existing battery energy storage equipment.

[0039] It should be noted that the specific structure of the energy storage compartment 10 can be as follows: Figure 1 The energy storage cabin 10 shown is configured as a cabin body 12 with a single-layer structure; Fig. 9 The energy storage cabin 10a shown is configured as a cabin body 12a with a double-layer structure. Figure 1 The energy storage cabin 10 shown is used as a basic structure, and based on this, more layers are stacked vertically. Energy storage cabins 10 with different layer structures can accommodate energy storage boxes 13 with different layers, for example, Fig. 9 The number of energy storage boxes 13 provided in the energy storage compartment 10a shown is Figure 1 The number of energy storage boxes 13 set in the energy storage compartment 10 shown is doubled, and different numbers of battery modules 131 can be stored. This application only shows a single-layer structure and a double-layer structure for exemplary explanation. In the specific application process, the energy storage compartment 10 with more layers can also be configured according to needs, for example, three layers or more layers. This embodiment does not limit this, but it does not limit the scope of protection of this application. Based on this, the specific structure of the device can be at least one such as Figure 1 The energy storage compartment 10 shown may also include at least one Fig. 9The energy storage compartment 10a shown can also be configured as a mixed configuration of the energy storage compartment 10 and the energy storage compartment 10a, which is not specifically limited in this embodiment. For ease of explanation, in the following specific description, only an example of the device including at least one energy storage compartment 10 is shown for exemplary explanation. At the same time, if the energy storage compartment 10 is configured as multiple, the open ends 11 of the multiple energy storage compartments 10 are arranged oppositely or in reverse or in the same direction, which can be adjusted accordingly according to actual needs.

[0040] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, a storage space 30 is formed inside the cabin 12, and an opening 11 is formed on one side of the cabin 12, the opening 11 is connected to the storage space 30, and the retracting mechanism 20 is arranged on the side of the opening 11 of the cabin 12, so that the energy storage box 13 can be movably received from the opening 11 to the storage space 30 through the retracting mechanism 20. The inner side wall of the cabin 12 protrudes toward the storage space 30 to form at least one set of track beams 14, that is, in Figure 3 From the perspective shown, the inner wall of the cabin 12 on the left (i.e., the first inner wall 121) protrudes toward the accommodating space 30 to form the track beam 14 on the left, and the inner wall of the cabin 12 on the right (i.e., the second inner wall 122) protrudes toward the accommodating space 30 to form the track beam 14 on the right (in short, the track beam 14 on the left and the track beam 14 on the right protrude oppositely), and a group of track beams 14 is defined by the track beams 14 on the left and the track beams 14 on the right. Accordingly, the guide beam 21 is arranged in the extension direction of the track beam 14 toward the opening 11, and the arrangement position of the guide beam 21 corresponds to the formation position of the track beam 14, that is, in Figure 6 In the perspective shown, the left track beam 14 is provided with a guide beam 21 on the left side in the extension direction of the opening 11, and the right track beam 14 is provided with a guide beam 21 on the right side in the extension direction of the opening 11, and a group of guide beams 21 is defined by the guide beams 21 on the left side and the guide beams 21 on the right side. Based on this, a single group of track beams 14 and a single group of guide beams 21 are docked to form a track for the energy storage box 13 to move back and forth. When the energy storage box 13 needs to be placed in the cabin 12, the energy storage box 13 is pushed into the accommodating space 30 through the track and placed on the single group of track beams 14. At the same time, when the battery module 131 in the energy storage box 13 needs to be inspected or replaced, the energy storage box 13 is pulled out of the accommodating space 30 through the track, and after the inspection, the energy storage box 13 is pushed into the accommodating space 30 through the track, thereby facilitating the inspection or replacement of the battery module 131.

[0041] It should be noted that when the energy storage box 13 is stored in the cabin 12, a set of track beams 14 is used to place at least one energy storage box 13, that is, a set of track beams 14 can be used to place one energy storage box 13, or multiple energy storage boxes 13 can be placed at the same time, and multiple energy storage boxes 13 are stacked and placed in sequence. Preferably, a single energy storage box 13 is placed on a single set of track beams 14, thereby not only ensuring the stability of the placement of the energy storage box 13 in the cabin 12, but also facilitating the maintenance or replacement of the battery module 131 in the single energy storage box 13.

[0042] At the same time, Figure 3 , Figure 7 and Figure 8 As shown, at least one energy storage box 13 is arranged in the accommodating space 30, and the energy storage box 13 is used to store the battery module 131, and a high-voltage box 23 is arranged outside the energy storage box 13. The battery module 131 is composed of a plurality of battery modules (not marked), and the battery module is formed by combining single lithium batteries in series and parallel. A moving part 15 is arranged on the bottom wall or side of the energy storage box 13, and the energy storage box 13 is placed on the track beam 14 through the moving part 15. The moving part 15 can also facilitate the energy storage box 13 to move back and forth on the track formed by the docking of the track beam 14 and the guide beam 21. More specifically, the energy storage box 13 is equipped with a basin-shaped box body 132 and a cover plate 133. The cover plate 133 is covered on the basin-shaped box body 132 to construct a closed energy storage cavity 134. The basin-shaped box body 132 and the cover plate 133 are both made of concrete composite materials. The moving member 15 is disposed on both sides of the basin-shaped box 132 near the bottom surface, and a supporting member (not shown, for example, a steel bar frame) is embedded inside the basin-shaped box 132, and the connecting portion of the moving member 15 is welded and fixed to the supporting member. Fig.12 As shown, an angled joint plate 141 is embedded in the bend of the track beam 14, and the angled joint plate 141 extends along the extension direction of the track beam 14, so that the energy storage box 13 is placed on the angled joint plate 141 through the moving member 15, and the strength of the track beam 14 is enhanced by the angled joint plate 141, the risk of collapse of the track beam 14 is reduced, and the friction between the moving member 15 and the track beam 14 is reduced when the energy storage box 13 moves back and forth on the track beam 14. Preferably, the angled joint plate 141 is constructed as a vertical angled long steel strip.

[0043] If multiple energy storage boxes 13 are provided in the cabin 12, the multiple energy storage boxes 13 can be provided as Figure 3The single row shown is arranged vertically in sequence, or multiple rows can be arranged vertically in sequence. As for the specific arrangement of multiple energy storage boxes 13, as long as the track formed by the docking of the track beam 14 and the guide beam 21 can be used to realize the energy storage box 13 from the opening 11 to be movably accommodated in the accommodating space 30, this embodiment does not make specific restrictions. If the energy storage boxes 13 in the cabin 12 are arranged vertically in multiple rows, track beams 14 can be protruded between each row of energy storage boxes 13 to respectively place the energy storage boxes 13. In addition, the above-mentioned example of defining a group of track beams 14 by two track beams 14 is used for illustrative explanation, and correspondingly, the example of defining a group of guide beams 21 by two guide beams 21 is used for illustrative explanation, but in the present application, the specific number of track beams 14 in a single group of track beams 14 and the specific number of guide beams 21 in a single group of guide beams 21 are not limited, as long as the energy storage box 13 can be placed by a single group of track beams 14, and the single group of track beams 14 and the single group of guide beams 21 can be connected to form a track for the reciprocating movement of the energy storage box 13.

[0044] Ginseng Figure 5 and Figure 6 As shown, in one embodiment, the fixing frame 22 includes: a support rod 221 disposed transversely at the open end 11 of the energy storage cabin 10 to support a single set of guide beams 21, a first fixing rod 222 disposed vertically at the open side 11 of the energy storage cabin 10 to support a single guide beam 21, and a second fixing rod 223 disposed longitudinally and fixedly connected to the open end 11 of the energy storage cabin 10 and the first fixing rod 222, respectively. Figure 3 In the perspective shown, the two ends of the support rod 221 are respectively fixedly assembled with the side portion of the cabin 12 on the left (i.e., the first side portion 123) and the side portion of the cabin 12 on the right (i.e., the second side portion 124), thereby realizing a horizontal arrangement at the open end 11 of the energy storage cabin 10, and a single group of guide beams 21 are placed on the support rod 221 to support the guide beams 21. The first fixing rod 222 is arranged vertically and fixedly assembled with the single guide beam 21, the second fixing rod 223 is arranged longitudinally and fixedly assembled with the first fixing rod 222, and the second fixing rod 223 is also fixedly assembled with the open end 11 of the energy storage cabin 10, thereby realizing the support of the guide beam 21 by the first fixing rod 222 and the second fixing rod 223, and supporting the guide beam 21 by the support rod 221, thereby ensuring the stability of the guide beam 21. If a single group of guide beams 21 is provided to include two guide beams 21, two first fixing rods 222 and second fixing rods 223 are correspondingly arranged to independently fix the single guide beam 21.

[0045] It should be noted that the above only shows a specific implementation of the fixing frame 22, and other structures can also be used to set the fixing frame 22, as long as the fixing frame 22 can support the guide beam 21 to ensure the stability of the guide beam 21. This embodiment does not make any specific limitations on this.

[0046] Ginseng Figure 6 As shown, in one embodiment, the side wall of the cabin body 12 near the open end 11 of the energy storage cabin 10 symmetrically opens first mounting holes (i.e., first mounting holes 125 and first mounting holes 126) for detachable assembly of the support rod 221, and the first fixing rod 222 opens a second mounting hole (i.e., second mounting hole 224 or second mounting hole 225) for detachable assembly of the guide beam 21. Figure 6 In the perspective shown, the side portion of the cabin body 12 located on the left (i.e., the first side portion 123) is vertically provided with a plurality of first mounting holes 125, and the side portion of the cabin body 12 located on the right (i.e., the second side portion 124) is vertically provided with a plurality of first mounting holes 126, and the first mounting holes 125 and the first mounting holes 126 are symmetrically provided, and the two ends of the support rod 221 are respectively detachably assembled with the first side portion 123 and the second side portion 124 through the first mounting holes 125 and the first mounting holes 126. Correspondingly, the first fixing rod 222 located on the left is vertically provided with a plurality of second mounting holes 224, and the first fixing rod 222 located on the right is vertically provided with a plurality of second mounting holes 225, and the second mounting holes 224 and the second mounting holes 225 are symmetrically provided, and the guide beam 21 located on the left is detachably assembled with the first fixing rod 222 through the second mounting holes 224, and the guide beam 21 located on the right is detachably assembled with the second fixing rod 222 through the second mounting holes 225. The support rod 221 is assembled with different first mounting holes 125 and first mounting holes 126 to adjust the position of the support rod 221, and the two guide beams 21 are assembled with different second mounting holes 225 and second mounting holes 225 to adjust the position of the guide beam 21. After the adjustment, the guide beams 21 are respectively connected to different groups of track beams 14 to form tracks for different energy storage boxes 13 to move back and forth, so as to facilitate the inspection or replacement of different energy storage boxes 13.

[0047] It should be noted that, in the above description, a single set of guide beams 21 are respectively connected to different sets of track beams 14 to ensure the reciprocating movement of each energy storage box 13. In one embodiment, multiple sets of guide beams 21 may be provided, so that multiple sets of guide beams 21 are respectively connected to multiple track beams 14, thereby ensuring the reciprocating movement of each energy storage box 13. Preferably, a single guide beam 21 is respectively connected to multiple sets of track beams 14, which not only further simplifies the mechanical complexity of the retracting and releasing mechanism 20, but also facilitates the operation of the operator, thereby facilitating the inspection and repair of the battery module 131 in the energy storage box 13. At the same time, in order to further facilitate the operator to inspect or replace the battery module 131 in the energy storage box 13, the retracting and releasing mechanism 20 also includes: a movable net (not shown) arranged between two second fixed rods 223 arranged opposite to each other. In actual application scenarios, the operator can stand on the movable net to inspect or replace the battery module 131.

[0048] Ginseng Figure 1 and Figure 2 As shown, the energy storage cabin 10 also includes: a hatch 16 pivotally connected to the side wall of the cabin body 12, and the hatch 16 and the cabin body 12 are enclosed to form a storage space 30, and the hatch 16 is separated from the end of the open 11 of the cabin body 12 by a certain distance. The opening and closing of the hatch 16 controls the activity and closure of the open 11, and the cabin body 12, the hatch 16 and the energy storage box 13 are all concrete composite structures made of concrete composite materials. After a certain fire prevention design, the concrete composite structure has a fire resistance performance due to the structural characteristics of the internal solidified material, and the melted concrete still has a strong pressure bearing capacity even in the event of a fire. Therefore, the concrete composite structure has better fire resistance than the metal sheet metal structure, and thus has higher safety. At the same time, the hatch 16 is separated from the open 11 of the cabin body 12 by a certain distance, that is, the cabin body 12 extends horizontally outward by one end from the position of the hatch 16 to form a fireproof partition area 17, thereby further improving the fireproof partition performance of the energy storage cabin 10.

[0049] Regarding the docking method between the track beam 14 and the guide beam 21, in one embodiment, Fig.11 As shown, the inner wall of the hatch 16 protrudes toward the accommodating space 30 to form an auxiliary beam 161 corresponding to the single set of track beams 14; when the hatch 16 is opened, the track beam 14, the auxiliary beam 161 and the guide beam 21 are connected in sequence to form a track for the energy storage box 13 to move back and forth. Figure 6 As shown, when the cabin door 16 is opened, the guide beam 21 extends into the cabin body 12 and docks with the track beam 14 to form a track for the energy storage box 13 to move back and forth.

[0050] At the same time, in one embodiment, if multiple energy storage compartments 10 are arranged opposite to each other from the open side 11, Fig.10 As shown, two energy storage cabins 10a are arranged opposite to each other from the opening 11 as an example for exemplary explanation. The two ends of the second fixing rod 223 are respectively fixedly connected to the opening 11 ends of the two energy storage cabins 10a arranged opposite to each other, and multiple second fixing rods 223 can be arranged, and the two energy storage cabins 10a share a set of guide beams 21, that is, the two ends of the guide beam 21 are respectively placed on the support rod 221 arranged at the opening 11 end of the energy storage cabin 10a on the left and the support rod 221 arranged at the opening 11 end of the energy storage cabin 10a on the right, and the middle part of the guide beam 21 is assembled with the first fixing rod 222, so that the two energy storage cabins 10a share one retracting and releasing mechanism 20, which not only simplifies the complexity of the mechanical structure, but also ensures the stability of the guide beam 21, thereby further ensuring the stability of the entire retracting and releasing mechanism 20.

[0051] Ginseng Figure 5As shown, in one embodiment, the retracting and releasing mechanism 20 further includes: a driving member (not shown) disposed at one side of the end of the opening 11 of the energy storage box 13 to drive the energy storage box 13 to move back and forth on the track formed by the track beam 14 and the guide beam 21. The driving member can be, for example, an electric hoist, etc., disposed at the end of the energy storage box 13 close to the opening 11 to drive the energy storage box 13 to move back and forth.
