Description

Technical Field

[0001] The present invention relates to the technical field of energy storage equipment, and in particular to a liquid-cooled energy storage container system equipment. Background Art

[0002] As global demand for renewable energy continues to grow, energy storage systems, as a key means of addressing unstable energy supply and peak-to-valley power fluctuations, are becoming an indispensable part of the new energy sector. Among the various energy storage forms, containerized liquid-cooled energy storage systems are highly favored due to their modular design, ease of transportation and installation, and adaptability to various environmental conditions. However, existing energy storage container solutions still have certain limitations in terms of safety protection, especially in fire prevention and control.

[0003] Currently, common energy storage containers on the market usually use traditional fire sprinkler systems to deal with possible fire accidents. The characteristic of this system is that fire sprinklers are deployed throughout the container. Once the fire detector is triggered, all sprinklers will start spraying water simultaneously to extinguish the flames. Although this design can control the spread of fire to a certain extent, it also has obvious defects: traditional sprinkler systems cannot accurately locate the fire point and instead spray over the entire area, which not only wastes water resources but may also cause unaffected battery modules to be soaked in water, causing unnecessary damage and secondary failures; and because water is a conductive medium, non-targeted water spraying may cause electrical short circuits and damage to other electrical equipment, further increasing repair costs and time; and large-scale water spraying will cause temporary or permanent shutdown of the entire energy storage system, affecting its normal operation and service continuity. Summary of the Invention

[0004] In view of this, the present invention provides a liquid-cooled energy storage container system equipment, which can solve the disadvantage that when a fire occurs in the battery module in the existing energy storage container, it is difficult to implement effective fire extinguishing measures for the specific faulty module.

[0005] The technical solution is: a liquid-cooled energy storage container system equipment, including an energy storage container and a revolving door, a revolving door is installed on the side of the energy storage container, liquid cooling plates are symmetrically installed in the energy storage container, and a liquid cooling mechanism is also provided in the energy storage container. The liquid cooling mechanism is used to cool the liquid cooling plate, and sliders are symmetrically provided on the liquid cooling plate. A battery pack is installed between the two sliders on the liquid cooling plate, and the bottom of the battery pack is in contact with the liquid cooling plate. The liquid cooling plate is used to cool the battery pack, and an interface is provided on the battery pack. An installation frame is symmetrically installed on the outside of the energy storage container, and a non-air-permeable waterproof Fire cloth, a driving mechanism is installed in the energy storage container, and a closing plate is also installed between the two sliders on the liquid cooling plate. The driving mechanism is used to drive the closing plate to move so that the closing plate can seal the battery pack in the non-breathable fireproof cloth in the installation frame, thereby isolating the faulty battery pack. Through holes are opened on the closing plate, and connecting wires are connected at intervals in the energy storage container. The ends of the connecting wires are connected to connectors, which are used to dock with the interfaces on the battery pack. A limit plate is provided on the liquid cooling plate, which is used to limit the movement of the connector. A blocking mechanism for blocking the through holes is provided on the closing plate.

[0006] Furthermore, the liquid cooling mechanism includes a refrigeration system, an input pipe and a return pipe. The refrigeration system is symmetrically arranged in the energy storage container. An input pipe is connected between the refrigeration system and the liquid cooling plate. The input pipe is used to input the coolant in the refrigeration system into the liquid cooling plate. A return pipe is also connected between the refrigeration system and the liquid cooling plate. The return pipe is used to return the coolant in the liquid cooling plate to the refrigeration system.

[0007] Furthermore, the driving mechanism includes a guide rod, a servo motor and a screw rod. The guide rods are symmetrically arranged in the energy storage container, and the closing plate is slidingly connected to the guide rods. The servo motor is symmetrically installed in the energy storage container, and the screw rod is connected to the output shaft of the servo motor. The closing plate is threadedly connected to the screw rod.

[0008] Furthermore, the shielding mechanism includes a block and a spring. The block is slidably provided on the closing plate. The block is used to shield the through hole on the closing plate. A spring is connected between the block and the closing plate.

[0009] Furthermore, the side of the stopper facing the joint is a slope, and the slope is used to enable the stopper to move and no longer block the through hole when the joint is squeezed.

[0010] Furthermore, a sealing strip is included. A sealing strip is installed on the side of the closing plate facing the battery pack, and the sealing strip is used to seal between the closing plate and the mounting frame.

[0011] Furthermore, it also includes an inflation mechanism, which includes a gas tank and a hose. The gas tank is installed on the top of the refrigeration system, and a hose is connected between the gas tank and the closing plate. The gas tank is used to input inert gas between the closing plate and the mounting frame to suppress the fire on the battery pack.

[0012] Furthermore, it also includes an alarm mechanism, which includes a power supply and control module and an alarm. The power supply and control module and the alarm are installed on the side of the energy storage container. The power supply and control module is used to control and power the alarm, and the alarm is used to give an alarm prompt.

[0013] The beneficial effects are: 1. The present invention can realize automatic identification and rapid isolation of faulty battery packs through the design of sliders, closing plates and driving mechanisms. When a battery pack has an abnormal temperature, the system can quickly isolate it from other normally working battery packs to prevent the spread of fire or thermal runaway effects. In addition, by equipping it with non-breathable fireproof cloth, an oxygen-deficient environment can be formed in the isolated enclosed space, effectively suppressing or extinguishing early fires and avoiding electrical short circuits and other equipment damage.

[0014] 2. This invention ensures that the battery pack operates at an appropriate operating temperature through a precisely controlled cooling system (liquid cooling plate + refrigeration system), reducing the risk of performance degradation or failure due to overheating, thereby improving the reliability and long-term stability of the entire energy storage system.

[0015] 3. The present invention provides an alarm mechanism, which can promptly alert the staff through the alarm when a battery pack has an abnormal temperature, thereby facilitating the staff to inform the maintenance personnel to carry out repairs in a timely manner.

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example: A liquid-cooled energy storage container system equipment, see Figures 1-9 As shown, it includes an energy storage container 1 and a revolving door 2; the revolving door 2 is rotatably installed in the middle of the front side of the energy storage container 1;

[0029] It also includes a liquid cooling plate 3, a liquid cooling mechanism, a slider 5, a battery pack 6, an interface 7, an installation frame 8, a non-breathable fireproof cloth 9, a driving mechanism, a closing plate 11, a connecting line 13, a joint 14, a limit plate 15 and a shielding mechanism; the liquid cooling plates 3 are installed symmetrically at intervals inside the energy storage container 1; a liquid cooling mechanism is also provided inside the energy storage container 1, and the liquid cooling mechanism is used to cool the liquid cooling plate 3; a slider 5 is provided on the top of the liquid cooling plate 3 for sliding symmetrically front and back; a battery pack 6 is installed between the two sliders 5 on the liquid cooling plate 3, and the bottom of the battery pack 6 is aligned with the top of the liquid cooling plate 3 The liquid cooling plate 3 is used to cool the battery pack 6. The battery pack 6 has a temperature feedback system inside. The temperature feedback system is used to detect the temperature of the battery pack 6 and provide feedback. The battery pack 6 is provided with an interface 7. The outside of the energy storage container 1 is symmetrically provided with a mounting frame 8. The mounting frame 8 is aligned with the battery pack 6 in the energy storage container 1. The mounting frame 8 is connected to a non-breathable fireproof cloth 9. The non-breathable fireproof cloth 9 can isolate the air, and the inside of the non-breathable fireproof cloth 9 is coated with a fireproof coating. The energy storage container 1 is provided with a driving mechanism, liquid cooling A closing plate 11 is further installed between the two sliders 5 on the plate 3. The battery pack 6 is located between the mounting frame 8 and the closing plate 11. The driving mechanism is used to drive the closing plate 11 to move, so that the slider 5 sends the faulty battery pack 6 into the non-breathable fireproof cloth 9 in the mounting frame 8, and then the closing plate 11 seals the battery pack 6 in the non-breathable fireproof cloth 9 in the mounting frame 8, thereby isolating the faulty battery pack 6 and placing the faulty battery pack 6 in a closed space. A through hole 12 is provided on the closing plate 11. The energy storage container 1 has a plurality of openings 12. Connecting wires 13 are connected at intervals; the ends of the connecting wires 13 are connected to connectors 14, which are used to pass through the through-holes 12 and connect with the interfaces 7 on the battery pack 6, thereby electrically connecting the battery pack 6 to the energy storage container 1; a limiting plate 15 is provided on the top of the liquid cooling plate 3, and the closing plate 11 is located between the limiting plate 15 and the battery pack 6, and the limiting plate 15 is used to limit the movement of the connector 14 so that when the battery pack 6 moves, the connector 14 can automatically detach from the interface 7 on the battery pack 6; a shielding mechanism for shielding the through-hole 12 is provided on the closing plate 11.

[0030] See Figure 2-Figure 4 As shown, the liquid cooling mechanism includes a refrigeration system 401, an input pipe 402 and a return pipe 403; the refrigeration system 401 is symmetrically arranged on the left and right sides of the rear side of the bottom of the energy storage container 1; the liquid cooling plate 3 and the refrigeration system 401 are connected by an input pipe 402, and the input pipe 402 is used to input the coolant in the refrigeration system 401 into the liquid cooling plate 3; the liquid cooling plate 3 and the refrigeration system 401 are connected by a return pipe 403, and the return pipe 403 is used to return the coolant in the liquid cooling plate 3 to the refrigeration system 401.

[0031] See Figure 6 and Figure 7As shown, the driving mechanism includes a guide rod 1001, a servo motor 1002 and a screw rod 1003; the guide rods 1001 are symmetrically arranged at intervals in the energy storage container 1, and the closing plate 11 is slidingly connected to the guide rods 1001; the servo motors 1002 are installed at symmetrical intervals in the energy storage container 1, and the servo motors 1002 are electrically connected to the energy storage container 1; the screw rod 1003 is connected to the output shaft of the servo motor 1002, and the closing plate 11 is threadedly connected to the screw rod 1003.

[0032] See Figure 8 and Figure 9 As shown, the shielding mechanism includes a block 1601 and a spring 1602; a block 1601 is slidably installed on the side of the closing plate 11 away from the battery pack 6, and the block 1601 is used to block the through hole 12 on the closing plate 11. The side of the block 1601 facing the connector 14 is a slope. When the connector 14 squeezes the slope, the block 1601 will move to no longer block the through hole 12, thereby facilitating the connector 14 to penetrate into the through hole 12 and dock with the interface 7; a spring 1602 is connected between the block 1601 and the closing plate 11.

[0033] When in use, the revolving door 2 is rotated to open, and then enter the energy storage container 1, and then the connector 14 is held to squeeze the inclined surface of the block 1601, so that the connector 14 squeezes the block 1601 to move and open, and the spring 1602 is compressed, so that the block 1601 no longer blocks the through hole 12, and then the connector 14 is held to penetrate into the through hole 12 and dock with the interface 7, so that the battery pack 6 is connected to the energy storage container 1, and then the energy storage container 1 is started to control the battery pack 6 to start energy storage, and then leave the energy storage container 1, and then the revolving door 2 is reversed and closed, and then the refrigeration system 401 is used to cool the battery pack 6. The cooling liquid is input into the liquid cooling plate 3 through the input pipe 402, so that the liquid cooling plate 3 absorbs heat from the battery pack 6, thereby cooling the battery pack 6 to prevent the battery pack 6 from being damaged due to excessive temperature during operation. After the cooling liquid in the liquid cooling plate 3 has absorbed heat, the cooling liquid will flow back to the refrigeration system 401 through the return pipe 403, so that the refrigeration system 401 can circulate the cooling liquid. When the temperature feedback system in the battery pack 6 detects a temperature abnormality, the temperature feedback system will send a signal to the energy storage container 1, and then the energy storage container 1 will control the corresponding servo motor 1. 002 drives the screw rod 1003 to rotate, so that the screw rod 1003 drives the closing plate 11, the slider 5 and the battery pack 6 to move to the side close to the installation frame 8. Since the joint 14 is restricted by the limiting plate 15, the limiting plate 15 will block the movement of the joint 14, so that the joint 14 is automatically separated from the interface 7 of the battery pack 6, thereby disconnecting the battery pack 6 from the energy storage container 1, and then stopping the battery pack 6 from storing energy. When the block 1601 on the closing plate 11 is separated from the joint 14, the spring 1602 returns to its original state, and the spring 1602 drives the block 1601 to move and close. , so that the block 1601 blocks the through hole 12 again. Then, when the battery pack 6 enters the installation frame 8, the battery pack 6 is placed in the non-breathable fireproof cloth 9. When the closing plate 11 contacts the installation frame 8, the closing plate 11 will seal the battery pack 6 in the non-breathable fireproof cloth 9 of the installation frame 8, so that the battery pack 6 is in a closed space. If there is a fire on the battery pack 6 at this time, the reduction of oxygen in the closed space can help suppress the flame. In this way, the faulty battery pack 6 can be automatically isolated to avoid affecting other battery packs 6 that are not faulty.

[0034] Later, when the maintenance personnel need to repair the faulty battery pack 6, they will remove the mounting frame 8 to make the faulty battery pack 6 leave the non-breathable fireproof cloth 9, and then the maintenance personnel will remove the faulty battery pack 6 from the slider 5, and then repair or replace the faulty battery pack 6, and then reinstall the repaired or replaced battery pack 6 onto the slider 5, and then reinstall the mounting frame 8 to make the faulty battery pack 6 be placed in the non-breathable fireproof cloth 9 again, and then rotate the revolving door 2 to open, and then enter the energy storage container 1 to control the corresponding servo motor 1002 to drive the screw rod 1003 to reverse and reset, so that the screw rod 1003 drives the closing plate 11 and the slider 5 and the battery pack 6 are moved to the side away from the installation frame 8 and reset, so that the closing plate 11 is separated from the installation frame 8, and then the closing plate 11 releases the seal on the battery pack 6 and the battery pack 6 leaves the non-breathable fireproof cloth 9. Then, the joint 14 is manually held and squeezed against the inclined surface of the block 1601, so that the joint 14 squeezes the block 1601 and moves it open. The spring 1602 is compressed, so that the block 1601 no longer blocks the through hole 12. Then, the joint 14 is manually held and inserted into the through hole 12 to dock with the interface 7, so that the battery pack 6 is connected to the energy storage container 1 again, so that the battery pack 6 starts to store energy again. Then, the battery pack 6 leaves the energy storage container 1, and the revolving door 2 is reversed and closed.

[0035] See Figure 9 As shown, a sealing strip 17 is also included; a sealing strip 17 is installed on the side of the closing plate 11 facing the battery pack 6 , and the sealing strip 17 is used to seal between the closing plate 11 and the mounting frame 8 .

[0036] When the closing plate 11 moves toward the side close to the mounting frame 8, the sealing strip 17 on the closing plate 11 will eventually come into contact with the mounting frame 8. The sealing strip 17 can seal between the closing plate 11 and the mounting frame 8, thereby improving the sealing performance in the enclosed space. When the closing plate 11 moves toward the side away from the mounting frame 8 and is reset, the sealing strip 17 on the closing plate 11 will separate from the mounting frame 8.

[0037] See Figure 10 As shown, it also includes an inflation mechanism, which includes a gas tank 18 and a hose 19; three gas tanks 18 are installed on the top of the refrigeration system 401, and the gas valve switches of the gas tanks 18 are electrically connected to the energy storage container 1 so that the energy storage container 1 can control the gas valve switches of the gas tanks 18; a hose 19 is connected between the gas tanks 18 and the closing plate 11, and the gas tanks 18 are used to input inert gas between the closing plate 11 and the mounting frame 8 to suppress the fire on the battery pack 6.

[0038] By providing an inflation mechanism, when the energy storage container 1 receives an abnormal signal from the temperature feedback system in the battery pack 6, the energy storage container 1 will control the gas valve switch of the gas tank 18 to be open for a period of time, so that the inert gas in the gas tank 18 is input between the sealing plate 11 and the mounting frame 8, thereby suppressing the fire on the battery pack 6; after a period of time, the energy storage container 1 will automatically control the gas valve switch of the gas tank 18 to be closed.

[0039] See Figure 10 As shown, an alarm mechanism is also included, which includes a power supply and control module 20 and an alarm 21; the power supply and control module 20 and the alarm 21 are installed on the upper left front side of the energy storage container 1, and the power supply and control module 20 is located in front of the alarm 21. The power supply and control module 20 is electrically connected to the energy storage container 1. The power supply and control module 20 is used to control and power the alarm 21, and the alarm 21 is used for alarm prompts.

[0040] By setting up an alarm mechanism, when the energy storage container 1 receives an abnormal signal from the temperature feedback system in the battery pack 6, the energy storage container 1 will send the signal to the power supply and control module 20, and then the power supply and control module 20 will supply power to the alarm 21 and control the alarm 21 to start the alarm, thereby reminding the staff, so that the staff can promptly inform the maintenance personnel to perform maintenance. The use of a separate power supply and control module 20 to power the alarm 21 can still provide power to the alarm 21 to sound an alarm when the energy storage container 1 is powered off due to a battery pack 6 failure. Later, when the maintenance personnel completes the repair or replacement of the faulty battery pack 6, they can control the power supply and control module 20 in the energy storage container 1 to power off the alarm 21 and control the alarm 21 to stop the alarm.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
