Description

Technical Field

[0001] This utility model relates to the field of lithium battery energy storage cabinet technology, and in particular to an outdoor lithium battery storage cabinet. Background Technology

[0002] Energy storage cabinets, with lithium iron phosphate cells as the core energy storage unit and a BMS protection system, constitute a backup power system and are gradually replacing bulky, short-life lead-acid batteries in off-grid power stations. However, lithium-ion batteries have limitations due to the high chemical reactivity of lithium.

[0003] In scenarios such as overcharging or heat dissipation failure, a single lithium battery box is prone to thermal runaway. Furthermore, the combustion of lithium batteries may spread rapidly. If the fire cannot be extinguished in time, it can easily affect other lithium batteries in the entire energy storage cabinet, causing significant losses. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an outdoor lithium battery storage cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The cabinet includes a cabinet body, characterized in that a cabinet door is installed on the cabinet body; a support frame is horizontally installed in the lower middle part of the cabinet body, two rows of storage cabinets are vertically arranged between the support frame and the inner top plate of the cabinet body, a partition is arranged between the two rows of storage cabinets, a cavity is provided on the side of the storage cabinet away from the partition, a water tank is arranged between the support frame and the inner bottom plate of the cabinet body, and a through groove is provided on the support frame corresponding to the cavity position.

[0007] The locker has multiple compartments, each equipped with a temperature sensor. A push plate is located on the side of the compartment closest to the cavity, and an opening and closing plate is located on the side of the compartment away from the partition. The push plate is driven by a hydraulic rod, which is located inside the partition.

[0008] In addition, the preferred structure is that a support frame is horizontally installed in the lower middle part of the cabinet, two rows of storage cabinets are installed between the support frame and the top inner side of the cabinet, a water tank is installed between the support frame and the bottom plate of the cabinet, and a through groove is provided above the support frame corresponding to the cavity position.

[0009] In addition, a preferred structure is that a push plate is provided on the side of the cabinet near the cavity, and a hydraulic rod is provided inside the push plate.

[0010] In addition, a preferred structure is that the cabinet has a hinged panel on the side away from the partition.

[0011] The beneficial effects of this utility model are as follows:

[0012] In the event of a single lithium battery catching fire, the lithium battery can be quickly pushed out of the opening and closing plate by a pusher plate and fall into the water tank below. The cooling water will quickly cool the battery down and retard the flame, thus preventing the fire of a single lithium battery from affecting the entire energy storage cabinet and reducing losses.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5An outdoor lithium battery storage cabinet includes a cabinet body 1, a cabinet door 2, a buzzer 3, an exhaust fan 4, a water valve 5, a hinge 6, a display 7, a water tank 8, a partition 9, a storage cabinet 10, and a support frame 12. Cabinet 1 is rotatably connected to cabinet door 2 via hinge 6. Sealing cotton is installed on the inside of cabinet door 2, and a door lock is installed on cabinet door 2. A heat dissipation hole is provided at the top of cabinet 1, and an exhaust fan 4 is installed at the position of the heat dissipation hole at the top of cabinet 1. A display 7 and a buzzer 3 are also provided at the top of cabinet 1. Through the heat dissipation holes at the top of cabinet 1, the outside of cabinet door 2, both sides of exhaust fan 4, and the top of shelf 10, the heat inside can be carried out and replaced during the charging of lithium battery for heat dissipation. In addition, two rows of shelves 10 are vertically arranged between support frame 12 and the inner top plate of cabinet 1, and a partition 9 is arranged between the two rows of shelves 10. A water tank 8 is arranged between support frame 12 and the inner bottom plate of cabinet 1, and the corresponding cavity position on support frame 12 is a through groove.

[0021] The storage cabinet 10 has multiple compartments, each equipped with a temperature sensor (WRP-230 platinum-rhodium thermocouple). A push plate is located on the side of each compartment closest to the cavity, and an opening / closing plate is located on the side of the compartment furthest from the partition 9. The push plate is driven by a hydraulic rod, which is located within the partition 9. The upper part of the opening / closing plate is rotatably connected to the inner wall of the compartment via a rotating column. Both sides of the opening / closing plate have locking blocks, the other end of which is rotatably mounted on the storage cabinet wall and driven to rotate by a servo motor. The opening / closing plate is opened and closed by rotation. The storage cabinet 10 also contains multiple horizontally and evenly installed shelves for storing lithium batteries. A water tank 8 contains cooling water and has an inlet and an outlet.

[0022] In this embodiment, if a sudden temperature change occurs, the WRP-230 platinum-rhodium thermocouple temperature sensor will detect it and display it on the display 7. Simultaneously, the buzzer 3 will sound to alert those nearby. At the same time, the latches on both sides of the opening and closing plate will rotate via a servo motor, no longer limiting the opening and closing plate. The push plate of the inner partition 9 of the storage cabinet 10 will activate, and the hydraulic rod inside the push plate will push the plate forward, moving the lithium battery outward. When the battery encounters the corresponding opening and closing plate, the partition 9 and the rotating column at the top of the opening and closing plate will cause the opening and closing plate to rotate under force, pushing the lithium battery out of its corresponding shelf and causing it to fall into the water tank 8 for fire extinguishing. During maintenance of the energy storage cabinet, the water in the water tank 8 is drained through the water valve 5, then pulled out through the handle in the middle of the outer side of the water tank 8, cleaned, and placed back into the cabinet 1. Water is then introduced through the through-slot of the support frame 12.

[0023] In this invention, through the design of the storage cabinet 10, support frame 12 and partition 9, when a single lithium battery catches fire, the lithium battery can be quickly pushed out of the opening and closing plate by the push plate and fall into the water tank below. It is then quickly cooled down and flame-retarded by being immersed in cooling water, thereby avoiding the impact of a single lithium battery catching fire on the entire energy storage cabinet and reducing losses.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
