[0002] With the rapid development of the new energy industry, the safety and stability of new energy storage systems, as one of the key technologies supporting the widespread application of renewable energy, are increasingly valued. However, during the storage and operation of new energy batteries, how to effectively deal with potential risks such as increased battery temperature and fire has become an urgent problem to be solved.

[0003] Traditional new energy storage protection devices often have problems such as complex operation, high energy consumption, poor cooling effect and insufficient emergency response capabilities. On the one hand, these devices are in working condition when the battery is not placed, which not only increases unnecessary energy consumption, but also may cause premature wear of mechanical parts. On the other hand, traditional cooling methods are often single and inefficient, and it is difficult to meet the heat dissipation requirements of new energy batteries under long-term high-load operation. In addition, in emergency situations, such as fires, traditional devices often lack a quick and effective self-rescue mechanism, making it difficult to ensure the safety of batteries and surrounding equipment. Summary of the invention

[0014] The present invention provides a protective device for new energy storage, which has the following beneficial effects: First, the device realizes adaptive fixation and start-up of new energy batteries through the design of lifting mechanical structure. When the battery is not placed, the lifting drive frame and the drive motor are in a non-working state, which effectively avoids unnecessary energy consumption and wear. When the battery is safely placed in the storage frame, the lifting mechanism is automatically triggered by gravity, and the limit rod and the lifting drive guide rod are plugged in and fixed to ensure the stable operation of the device. This design not only simplifies the operation process, but also improves the automation level of the system.

[0015] Secondly, the device integrates an efficient cooling system. Through the linkage between the follower gear and the worm gear, it achieves the dual cooling effect of the cooling fan and the coolant circulation. The cooling fan directly blows the low-temperature gas to the battery to achieve initial cooling; while the coolant circulation performs efficient heat exchange through the heat exchange coil to further reduce the battery temperature. This composite cooling method not only improves the cooling efficiency, but also ensures the stability and safety of the battery under long-term high-load operation.

[0016] In addition, the device also has an intelligent emergency release function. When an abnormal situation such as a fire occurs in the energy storage protection box, the fire alarm can quickly transmit the signal to the controller and trigger the electromagnetic block to separate the limit rod from the lifting drive guide rod. Subsequently, under the elastic force of the first spring, the storage frame and the battery as a whole are quickly lifted out of the danger zone, and the drive motor is powered off and stops working. This function greatly improves the response speed and self-rescue ability of the device in emergency situations, ensuring the safety of the battery and surrounding equipment.

[0017] In summary, the protective device for new energy storage in this embodiment achieves efficient cooling and emergency separation protection for new energy batteries through its unique working principle and structural design, providing comprehensive and reliable protection for the safe and stable operation of new energy storage systems. Its high degree of automation, good cooling effect, rapid emergency response and other beneficial technical effects make the device have broad application prospects and promotion value in the field of new energy.

[0032] The working principle of this embodiment: When the new energy battery has not yet been placed in the storage frame 9, the lifting drive guide rod 301 in the lifting drive frame 3 is in the initial position (i.e., the higher position) due to the elastic force of the first spring 306. At this time, the connection switch 501 is not squeezed by the lifting drive guide rod 301, and the drive motor 304 is in a power-off state. When the new energy battery in the energy storage protection box 1 is safely placed in the storage frame 9, the lifting drive frame 3 is pressed downward by gravity, and the limit rod 602 is plugged and fixed to the lifting drive guide rod 301. At this time, the connection switch 501 is squeezed by the lifting drive guide rod 301, the drive motor 304 is in a power-on state, and the device is in a normal working state. At this time, if the system detects that the battery or ambient temperature has risen and the cooling system needs to be started, a command is issued to the drive motor 304 through the control box 2.

[0033] Once the system is started, the driving motor 304 drives the driving gear 303 to rotate through the coupling, and the driving gear 303 meshes with the follower gear 401 in the follower frame 4, so that the follower gear 401 rotates synchronously. The rotation of the follower gear 401 not only drives the cooling fan 402 located on its rotating shaft, blowing the low-temperature gas in the cooling coil 8 to the new energy battery in the storage frame 9 to achieve preliminary cooling; at the same time, the rotation of the follower gear 401 also drives the worm wheel 702 and the booster auger 704 and the associated impeller 703 connected thereto to rotate through the worm 701. The booster auger 704 delivers the coolant in a directional manner in the circulating booster pipe 10, while the associated impeller 703 blows the airflow to the heat exchange coil 1001, further promoting the heat exchange efficiency of the coolant.

[0034] The coolant forms a closed loop between the circulating booster pipe 10 and the cooling coil 8, and achieves efficient heat exchange through the heat exchange coil 1001. In this process, the high-temperature coolant, driven by the booster auger 704, enters the cooling coil 8 in the energy storage protection box 1 through the lower heat exchange coil 1001, absorbs the heat emitted by the battery, and turns into low-temperature coolant, and then flows back to the circulating booster pipe 10 through the higher heat exchange coil 1001 to continue to participate in the circulation.

[0035] In addition, when an abnormal situation occurs in the energy storage protection box 1, such as a fire, the fire alarm transmits a signal to the controller in the control box 2. The controller then controls the electromagnetic block 601 to work, and the magnetic force generated by the electromagnetic block 601 attracts the limit rod 602 to move outward, so that the limit rod 602 is separated from the lifting drive guide rod 301. At this time, the lifting drive guide rod 301 moves up rapidly under the elastic force of the first spring 306, driving the upper drive frame 302, the suspension arm 305 and the storage frame 9 connected thereto to rise as a whole, realizing the rapid separation of the new energy battery, and at the same time, the drive motor 304 stops working due to the disconnection of the circuit, ensuring the safety of the battery in an emergency.
