[0036] Wherein, the middle part of the upper top wall and the lower bottom wall of the storage cavity of storage cabinet 1 is equipped with action slot 5, and turning member is arranged in action slot 5.

[0037] Action slot 5 is arranged in the middle part of storage cabinet 1, so that storage rack 2 is in the middle of ejection, and the both sides of storage cabinet 1 can have enough maintenance or repair space, so that maintenance personnel and operating personnel can carry out repair to cable in storage rack 2, improve the flexibility and repair convenience of entire energy storage system;

[0038] In the embodiment, storage rack 2 is pushed out from the position in storage cabinet 1 and turns under the turning operation of turning member, so that operating personnel or maintenance personnel can carry out repair, loading or pick and place of battery module 8.

[0039] Through the mutual cooperation of turning member and storage rack 2, the position of storage rack 2 can be adjusted, and the convenience and flexibility of maintenance personnel operation are improved.

[0040] Optionally, the steering component includes an auxiliary plate 3, a steering rod 7, a steering drive mechanism, an ejector 4, and a steering switch 14. The auxiliary plate 3 is arranged in the action groove 5 and is slidably connected to the action groove 5. The ejector 4 is arranged on the side of the auxiliary plate 3 away from the cabinet door of the storage cabinet 1. One end of the ejector 4 is connected to one end of the auxiliary plate 3, and the other end of the ejector 4 is connected to the inner wall of the action groove 5. The storage rack 2 and the auxiliary plate 3 are hinged to form a hinge part 15. One end of the steering rod 7 is driven and connected to the steering drive mechanism to form a steering part, and the other end of the steering rod 7 is hinged to the storage rack 2.

[0041] The steering switch 14 is electrically connected to the steering drive mechanism, and controls the steering drive mechanism based on the steering switch.

[0042] like Figure 2 As shown, the auxiliary plate 3 is ejected along the groove direction of the action groove 5 under the ejection operation of the ejector 4, thereby driving the storage rack 2 to be ejected from the storage cavity. At the same time, during the ejection process, due to the steering operation of the steering part, the storage rack 2 is rotated 90° from its original direction to expose the wiring terminals on the back of the battery module 8, thereby facilitating maintenance and repair personnel to carry out inspection and wiring.

[0043] Optionally, the end surface of the auxiliary plate 3 that contacts the action groove 5 is provided with a limiting groove 13, and the end surface of the action groove 5 that contacts the auxiliary plate 3 is provided with a limiting protrusion 12, and the limiting protrusion 12 and the limiting groove 13 are adapted to each other.

[0044] Among them, the contact area between the auxiliary plate 3 and the action groove 5 is effectively improved by the adaptive placement structure of the limiting groove 13 and the limiting protrusion 12, ensuring that the auxiliary plate 3 can move smoothly.

[0045] Optionally, the ejection direction of the ejector 4 is parallel to the opening direction of the action slot 5; wherein the opening direction of the action slot 5 is directly opposite to the door direction of the storage cabinet 1. In this embodiment, the opening direction of the action slot 5 is perpendicular to the opening of the door, so that the storage rack 2 is ejected from the storage cabinet 1;

[0046] Optionally, the locking component includes a locking seat, a pull rod, a fixing plate 10, a limiting airbag 11, an air pump, an air release valve, and a air release button 9. The fixing plate 10 is arranged on one side end face of the locking seat to form a control panel. A accommodating cavity is provided on the locking seat body. The air pump is connected to the limiting airbag 11 through a connecting pipe to form an inflation part. The inflation part is arranged in the accommodating cavity. The air release valve is arranged on the limiting airbag 11 and is electrically connected to the air release button.

[0047] The deflation button is electronic and is turned on and off based on the on and off status of the deflation button 9 , thereby discharging the gas in the limiting airbag 11 and releasing the restriction on the battery module 8 .

[0048] Meanwhile, when the inflation pump inflates the limiting air bag 11, the limiting air bag 11 is inflated and bulges, thereby limiting the battery module 8 in the storage rack 2, so as to improve the limiting efficiency of the position of the battery module 8 and prevent the position of the battery module 8 from deviating to cause a fault.

[0049] In the embodiment, the limiting effect of the battery module 8 by the locking member enables the battery module 8 of different shapes to be used flexibly, improves the flexibility and self-adaptive ability of the battery module 8, and ensures that the entire system has a more extensive application scenario.

[0050] Optionally, the storage rack 2 is provided with at least one storage cavity 6, and the storage cavity 6 is used for placing at least one battery module 8.

[0051] When the battery module 8 is placed in the storage cavity 6 of the storage rack 2, the battery module 8 cannot be adapted to the size of the storage cavity 6 due to different models, at this time, the locking member is matched with the battery module 8 to limit the position of the battery module 8, so as to achieve the limiting and locking effect.

[0052] In addition, in the embodiment, the limiting air bag 11 is provided with a sub-cavity, and the sub-cavity is pre-provided with a fireproof material, which includes but is not limited to the following several kinds: expanded graphite powder, inorganic fireproof fiber, and fire-retardant gel (non-corrosive and non-conductive formula is selected);

[0053] The expanded graphite is an inert material, which forms a porous carbon layer after expansion, can block oxygen and absorb heat, and effectively inhibits the spread of flame. The expanded graphite does not produce corrosive gas or residue, and has no effect on the electrical performance of the battery module 8. The protective layer formed after expansion can directly cover the surface of the fire source, and is suitable for fireproof and heat insulation of the battery module 8. It is suitable to be installed around the battery module 8, and can provide initial fire-retardant protection when high temperature is encountered.

[0054] The inorganic fireproof fiber (such as ceramic fiber) has excellent high-temperature resistance and heat insulation effect, does not burn and release gas. It can form a stable heat shield to delay the spread of heat to the battery module 8. The ceramic fiber is inorganic and does not contain corrosive or conductive components, and will not affect other battery modules 8 and can maintain stable structure at high temperature. At the same time, the inner wall composite layer of the limiting air bag 11 forms an independent fireproof layer, which can still effectively protect the battery module 8 when the air bag is deflated.

[0055] The fire-retardant gel (selected from non-corrosive and non-conductive formula) can expand rapidly at high temperature to form a covering layer to block oxygen and has good heat insulation. Through a specific formula (such as a silicon-based gel), it can be ensured that the gel is non-conductive and non-corrosive after being heated. The use of a silicon-based fire-retardant gel avoids the corrosion or conductivity that the battery module 8 may be subjected to, and the expanded gel has the effect of isolating and cooling the fire source. The gel microcapsules can be placed inside the air bag and expand when the air bag is broken and contacts the air to cover the surface of the fire source, which is suitable for emergency fire protection of the battery module 8.

[0056] In the present embodiment, by arranging the fireproof material in the limiting air bag 11, the safety of the battery module 8 is effectively improved, and the position is also locked and limited, so that the entire system has good environmental adaptability, good fire protection effect, high locking convenience, and enhanced adaptability of the storage rack 2 to different modules.

[0057] Optionally, the distributed energy storage system further comprises a pulling stabilizing member, which is arranged on both sides of the storage rack 2 in the ejection direction and is detachably connected with the storage rack 2.

[0058] When the storage rack 2 and the storage cabinet 1 are relatively offset (when the ejector 4 ejects the storage rack 2 from the storage cabinet 1), the operator or the maintenance personnel can use the pulling stabilizing member according to the actual situation and lock the position of the storage rack 2, so as to limit the posture of the storage rack 2.

[0059] Optionally, the pulling stabilizing member comprises a pulling rod 17, a magnetic seat 18, and a pulling seat 19, the pulling seat 19 is arranged on the storage cabinet 1, one end of the pulling rod 17 is hinged with the pulling seat 19, and the other end of the pulling rod 17 is connected with the magnetic seat 18 to form a pulling part;

[0060] The pulling part is detachably adsorbed on the storage rack 2.

[0061] At the same time, the inner wall of the storage cabinet 1 is provided with a hidden cavity 16, and the hidden cavity 16 is matched with the circumference of the pulling rod 17;

[0062] In addition, the magnetic seat 18 generates an attractive force which is suitable to overcome the offset force of the storage rack 2, which is a technical means known to those skilled in the art, and thus will not be described here.

[0063] As shown in the figure, one end of the pulling rod 17 is hinged with the pulling seat 19, and at the same time, in the non-use state, the pulling rod 17 is hidden and placed in the hidden cavity 16 of the storage cabinet 1;

[0064] When the maintenance personnel or the operator is in the process of overhauling and maintaining the battery module 8 in the storage rack 2, the maintenance personnel and the operator pull the stable posture according to the actual needs, so as to ensure that the storage rack 2 will not be offset and turned.

[0065] The storage rack 2 is pulled and stabilized by the pulling and stabilizing member, so that the stability of the storage rack 2 is effectively improved, the stability of the posture of the storage rack 2 is realized, and the safety of the overhauling and maintenance is improved.

[0066] In addition, in the embodiment, a central processor is further included, the central processor is respectively connected with the turning member and the locking member in control, the turning member and the locking member are controlled based on the central processor, the processing capacity of the whole system is improved, and it is ensured that the whole system can accurately and reliably perform the energy storage operation.

[0067] The control connection of the central processor with the turning member and the locking member is a kind of technical means known to those skilled in the art, so in the embodiment, it will not be described one by one.

[0068] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-substantial changes and replacements made by those skilled in the art on the basis of the utility model belong to the range of protection required by the utility model.
