Description
Technical Field
[0001] The present invention relates to the technical field of electric power facilities, and in particular to an outdoor electric energy storage cabinet. Background Art
[0002] The outdoor power energy storage cabinet is an integrated energy storage device, which is mainly used to store and manage electric energy. It is widely used in power systems, communication base stations, industrial electricity and other fields. However, due to the peak and valley periods of electricity consumption, there are large differences in electricity consumption in different periods. However, the electricity generated by power generation equipment will be wasted if it is not used after it is manufactured. At the same time, renewable energy such as wind and solar energy has volatility. Therefore, in order to avoid energy waste, excess electricity will be stored in energy storage cabinets. The energy storage cabinets store electricity during low electricity consumption and release it during peak electricity consumption. It can also be used to balance the load of the power grid. When the main power supply fails, it can also be used to provide emergency power to ensure the operation of key equipment.
[0003] An outdoor power energy storage cabinet is a cabinet that is installed outdoors to store power. The outdoor energy storage cabinet can be deployed more conveniently, efficiently and safely, and is suitable for different power supply scenarios. A large number of battery packs and inverters are usually installed in the energy storage cabinet. When the energy storage cabinet stores and releases power, a large amount of heat is output, and the interior of the storage cabinet needs to be dissipated in time. However, when the battery pack is not storing and releasing power, the outside temperature is too high or too low, which will damage the battery. Existing outdoor power storage cabinets mostly use air-conditioning systems to adjust the internal temperature of the cabinet. The air-conditioning system is difficult to continuously maintain the battery at a suitable temperature. At the same time, long-term startup of the air-conditioning system will also increase energy consumption and maintenance costs. Therefore, there is a need for an outdoor power storage cabinet that can sustainably maintain the outdoor cabinet at a suitable temperature. Summary of the invention

When the secondary cabinet 2 rises and the pulling rod 22 contacts the arc frame 19, the deflection frame 21 rotates with the arc frame 19 to support the rotation of the ventilation plate 20. At this time, it is beneficial for the energy storage cabinet 1 to exchange heat through the gap between the ventilation plate 20 and the secondary cabinet 2.
[0033] like Figure 2-Figure 3 As shown, the energy storage cabinet 1 is connected to a cable, which passes through one side of the secondary cabinet 2 connected to a cabinet door 5, and the cable is rotationally connected to the tertiary cabinet 3. When the secondary cabinet 2 is raised or lowered, the cable rotates accordingly, and the cable moves in the gap between the secondary cabinet 2 and the tertiary cabinet 3.
[0034] In this embodiment, when the energy storage cabinet 1 is used for charging and discharging, the lifting component 4 pushes the secondary cabinet 2 to rise, and the conical top 15 and the receiving seat 16 are separated. At this time, the cable rotates as the secondary cabinet 2 rises. When the pull rod 22 contacts the arc frame 19, the deflection frame 21 rotates and drives the ventilation plate 20 to deflect and open. The handle 12 is turned, and the gear 14 drives the rack 10 to slide downward in the splicing groove 9. At this time, cabinet door 1 5 and cabinet door 2 6 are separated from sealing strip 1 7 and sealing strip 2 8. When the gear 14 and the rack 10 are separated, cabinet door 1 5 and cabinet door 2 6 can be rotated to open.
