Description

Technical Field

[0001] The utility model relates to the technical field of energy storage technology and power system regulation technology, in particular to a multi-compartment separated battery room. Background Art

[0002] A battery room is essentially a chamber housing lead-acid batteries, suitable for cranes on container quay cranes. Because cranes are extremely powerful, if they are simultaneously ascending, the resulting power consumption is significant, requiring significant grid power. If they are simultaneously descending, the resulting energy return is equally substantial. Therefore, by providing a battery room for energy storage and charging, multiple cranes can operate within their capacity without causing power outages. To ensure proper operation and maintenance of the battery pack, strict environmental requirements are imposed. For example, lead-acid batteries release hydrogen during charging, a flammable and explosive gas that requires good ventilation. Existing designs typically rely on natural ventilation, which is highly dependent on the external environment. For example, Chinese patent CN201420755081.1 discloses a battery room, which includes a battery room body. The battery room body is separated by a frame to form an air-conditioning room, a battery room and a battery control room. The air-conditioning room is connected to the battery room and the battery control room. The outer periphery of the battery room body is covered with steel plates. A mounting frame is fixedly installed in the battery room. Several groups of guide rails are respectively installed on the battery frame and the mounting frame. Each group of guide rails has a battery pack bracket that is movably matched with it. The battery pack bracket has a locking plate. Two battery packs are fixedly installed on the battery pack bracket. The upper cover of the battery pack has a vent, and the side wall of the battery pack has a fan. The above patent has good ventilation and heat insulation effects and can effectively prevent battery leakage. However, it uses a single-speed axial flow centrifugal fan for exhaust, and its energy consumption during operation is relatively high. At the same time, the air circulation of this solution is too simple. After the exhaust is completed, some exhaust gas will flow back. It can only meet the minimum usage requirements of the battery use environment.

[0003] Therefore, it is necessary for technical personnel in this field to provide a multi-separated battery room to separate the rooms for storing batteries and the rooms for operators, while improving the air circulation effect, preventing exhaust gas backflow, and ensuring safety of use. Utility Model Content

[0021] The battery compartment 11 houses multiple lithium-ion batteries 16. These batteries 16 are used to store electrical energy from the external power grid and to supply power to a power station, which is electrically connected to power-consuming equipment, such as cranes. When multiple cranes are operating simultaneously, the power / current demand is excessive. The batteries 16 are used to supply power to the power station, ensuring stability during the simultaneous operation of the cranes. When fewer cranes are in use, the batteries 16 store energy for the next power supply to the power station, thus achieving both energy storage and charging.

[0022] The operating room 12 is equipped with multiple cabinets 17, which are PCS cabinets. These PCS cabinets are common commercially available energy storage cabinets that can operate stably under different transformer voltages and provide efficient power conversion and storage. They can also quickly respond to and balance the power system, ensuring a stable power supply.

[0023] The control room 13 houses multiple auxiliary cabinets 18 and a main switch cabinet 19. The auxiliary cabinets 18 are EMS cabinets. These cabinets are typically cabinets or containers used in energy storage and power management systems. These cabinets include, but are not limited to, real-time alarms, event query statistics, remote control, and user rights management to ensure the safe and stable operation of the energy storage system while improving energy efficiency and ease of management.

[0024] A water cooling unit 21 is installed on the outdoor water cooling unit platform 15. The water cooling unit 21 is a common air-cooled water cooling unit on the market.

The water-cooled main unit is installed on the outdoor water cooling unit platform 15, and the water-cooled indoor unit is installed in the battery room 11 to cool the battery room 11. The utility model also includes other air-conditioning and refrigeration equipment. The main unit of the air-conditioning and refrigeration equipment is installed outside the room body 10, and the indoor unit of the air-conditioning and refrigeration equipment is installed in the operation room 12 and the control room 13 to cool the operation room 12 and the control room 13 in the room body 10. The specific structure will not be repeated here.

[0025] A transformer 20 is installed in the transformer chamber 14. The transformer 20 is electrically connected to the external power grid. The transformer 20 is electrically connected to the battery 16 in the battery chamber 11. The external power grid is passed into the battery 16 through the transformer 20, and the power supply of the external power grid to the power station is controlled within a fixed power range to ensure the stability of power transmission.

[0026] Electrical components are installed in the cabinet 17 , including but not limited to contactors and fuses. The electrical components are electrically connected to the battery 16 to control the switching and use of the battery 16 .

[0027] A control system is installed in the auxiliary cabinet 18. The control system is a computer control system. The control system is used to control the electrical components in the cabinet 17. The computer control system realizes human-computer interaction, automatically controls the electrical components, and continuously controls the energy storage and discharge of the battery 16.

[0028] The switch cabinet 19 is equipped with control elements, which are electrically connected to the electrical elements in the cabinet 17. The control system controls the control elements, which include circuit breakers and relays. The control elements are used to control the power of various devices in the room 10 and control the electrical connection between the transformer 20 and the battery 16.

[0029] In this example, see Figure 2 、 Figure 3A sealed door 23 is further provided on the room body 10 between the battery room 11, the operating room 12, the control room 13 and the transformer room 14. The battery room 11, the operating room 12, the control room 13 and the transformer room 14 are connected by the sealed door 23. When the sealed door 23 is closed, the battery room 11, the operating room 12, the control room 13 and the transformer room 14 are in a closed state and isolated from each other, thereby ensuring safety and stability in use.

[0030] Specifically, sealed doors 23 are respectively provided on two opposite walls in the battery room 11 , one sealed door 23 is close to the operating room 12 and connected to the operating room 12 , and the other sealed door 23 is close to the outdoor water cooling unit platform 15 and connected to the outdoor water cooling unit platform 15 .

[0031] The utility model adopts a separation method to install the battery room 11, the operating room 12, the control room 13 and the transformer room 14 separately from each other, thereby reducing the interference between the various devices therein and ensuring the stability of use between the various devices.

[0032] The battery compartment 11 is also equipped with multiple electric fans 22. The electric fans 22 penetrate the wall of the battery compartment 11 and connect the internal cavity of the battery compartment 11 with the external atmosphere. Some of the electric fans 22 are located on the side wall of the battery compartment 11 near the battery 16. One electric fan 22 faces each battery 16 to achieve targeted suction. One electric fan 22 is located above the sealed door 23, and another electric fan 22 is located above another sealed door 23.

[0033] The electric fan 22 located on the battery room 11 near the outdoor water cooling unit platform 15 exhausts air to the outside of the battery room 11, and the electric fan 22 located on the battery room 11 near the operating room 12 ventilates into the battery room 11, thereby achieving rapid discharge of exhaust gas in the battery room 11, and at the same time only the gas in the operating room 12 can be passed into the battery room 11, thereby preventing exhaust gas in the battery room 11 from entering the operating room 12, and finally the air in the battery room 11 is discharged into the atmosphere. Through one-way air circulation, backflow of exhaust gas is prevented, effectively ensuring safety of use.

[0034] In this embodiment, the electric fan 22 is a common industrial fan on the market. The electric fan 22 includes a valve body and a fan body. The valve body is a one-way valve. The valve body is used to control the exhaust of the battery chamber 11 to the outside without backflow, while ensuring the sealing effect of the battery chamber 11. The fan body is driven by a motor and can automatically exhaust to the outside according to usage needs, thereby ensuring the safety of the air in the battery chamber 11 and the convenience of operation.

[0035] The utility model adds multiple electric fans 22 and arranges them scientifically to quickly extract the air in the battery chamber 11 to the outside, prevents the lead-acid batteries stored in the battery room from releasing hydrogen during charging, and prevents the exhaust gas from flowing back, thereby ensuring safety in use.
