Preferably, it further comprises a first slider 17, the first slider 17 being threadedly connected to the first threaded rod 11, a second slider 18 being slidably connected to the guide rod 12, a driving motor 19 being fixedly connected to the left side of the first slider 17, a second threaded rod 20 being fixedly connected to the output shaft of the driving motor 19, the right end of the second threaded rod 20 being rotatably connected to the second slider 18, both ends of a slide bar 21 being respectively fixedly connected to the first slider 17 and the second slider 18, a mounting base 22 being threadedly connected to the second threaded rod 20, the mounting base 22 being slidably connected to the slide bar 21, a fire extinguisher canister 23 being fixedly connected to the bottom of the mounting base 22, a nozzle 24 being fixedly connected to the top of the mounting base 22, the discharge port of the fire extinguisher canister 23 being connected to the nozzle 24 via a delivery pipe 25, and a solenoid valve 26 being fixedly connected to the discharge port of the fire extinguisher canister 23.
Preferably, the fire early warning mechanism 5 further comprises: a control box 27, the control box 27 being fixedly connected inside the first cavity 3, and the control box 27 being connected to an operation screen 28, a communication receiver 29, and a power supply 30, a fire detector 31 being fixedly connected to the top of the inner wall of the second cavity 4, a first alarm 32 being fixedly connected to the top of the battery compartment 1, and the operation screen 28, communication receiver 29, power supply 30, fire detector 31, and first alarm 32 being electrically connected to the control box 27.
The beneficial effects of the above technical solution are as follows:
By dividing the battery compartment 1 into a first cavity 3 and a second cavity 4 with a partition 2, the battery boxes 37 in the energy storage mechanism 6 and the control system of the fire early warning mechanism 5 are installed in different cavities.
This prevents fires caused by overheating and thermal runaway of the battery boxes 37 during the energy storage operation of the battery compartment 1, avoiding overall damage to the battery compartment energy storage system and preventing significant L 4507577 economic losses. The fire early warning mechanism 5 monitors the internal fire situation of the battery compartment 1 in real-time. When the fire detector 31 fixed to the top of the battery compartment 1 detects a fire caused by overheating and thermal runaway, the first alarm 32 will sound, and the communication receiver in the control box 27 will transmit the warning information to the staff, enabling them to arrive on-site for handling. Simultaneously, the forward and reverse driving motor 14 fixed to the first mounting plate 13 will start operating. The forward and reverse driving motor 14 drives the first bevel gear 15 fixed to its output shaft to rotate, which engages with the second bevel gear 16 to rotate the first threaded rod 11 synchronously. The first slider 17 threadedly connected to the first threaded rod 11 will move up and down, while the second slider 18 fixedly connected to the first slider 17 through the slide bar 21 will slide up and down along the guide rod 12. The mounting base 22 threadedly connected to the second threaded rod 20 will move left and right along the slide bar 21 driven by the driving motor 19, adjusting the position of the mounting base 22 inside the battery compartment 1. When the mounting base 22 moves to the fire location, the solenoid valve 26 on the fire extinguisher canister 23 opens, releasing high-pressure gas from the fire extinguisher canister 23 through the delivery pipe 25 to the nozzle 24, which directs the high-pressure gas to the fire source to extinguish the fire. After extinguishing the fire, the solenoid valve 26 closes, and the mounting base 22 of the fire early warning mechanism 5 resets.
By setting up the fire early warning mechanism 5 in the battery compartment energy storage system, the present invention ensures timely warnings and effective handling of fires caused by overheating and thermal runaway inside the battery compartment 1, preventing significant economic losses due to internal fires and greatly improving the operational safety of the battery compartment energy storage system. The present invention addresses the following problems of the existing technology: the lack of a fire early warning mechanism 5 in existing battery compartment 1 energy storage systems, leading to untimely warnings and ineffective handling of fires caused by overheating and thermal runaway, resulting in significant economic losses due to internal fires in the battery compartment 1.

A liquid filling port 64 is fixedly connected to the top of the buffer box 60, and a liquid exchange port 65 is fixedly connected to the bottom of the side wall of the buffer box 60.
The beneficial effects of the above technical solution are as follows:
By setting several mounting mechanisms 45 around the bottom of the battery compartment 1, the battery compartment 1 can be installed and fixed. The fourth slider 49 in the transmission assembly is slidably connected within the second sliding groove 48 embedded in the mounting base 46. The elastic force of the second spring L 4507577 50 causes the fourth slider 49 to move inward within the second sliding groove 48, while the first support rod 51 hinged to the top of the mounting base 46 swings inward through the connecting rod 53 hinged to the fourth slider 49, driving the fixing block 52 hinged to the first support rod 51 to move inward.
The lower end of the second support rod 54 hinged to the fixing block 52 also retracts inward, causing the second mounting plate 59 hinged to the top of the second support rod 54 to lift upward.
The guide columns 58 fixedly connected to both sides of the second mounting plate 59 slide upward within the first fixed sleeves 47. Simultaneously, the sliding rod 55 fixedly connected to the fixing block 52 slides within the second fixed sleeve 56, compressing the third spring 57. This achieves stable support for the battery compartment 1 through the mounting mechanisms 45. When the battery compartment 1 experiences severe vibrations, the elastic force of the second spring 50 and the third spring 57 in the mounting mechanisms 45 causes the fourth slider 49 to drive the connecting rod 53 to keep the first support rod 51 swinging inward, while the fixing block 52 moves outward under the influence of the elastic force, ensuring that the second support rod 54 hinged to the fixing block 52 keeps the second mounting plate 59 lifted upward, providing stable support for the battery compartment 1 during severe vibrations and reducing the impact of vibrations on the internal energy storage system of the battery compartment 1. Furthermore, the rotating sleeve 62 in the buffer assembly, which is rotatably connected to the guide columns 58, provides resistance through the several buffer plates 63 fixedly connected to the rotating sleeve 62 rotating in the buffer fluid 61 inside the buffer box 60. The buffer fluid 61, which can be viscous liquids like glycerin, increases the rotational friction between the rotating sleeve 62 and the guide columns 58, providing buffering for the up-and-down movement of the guide columns 58 within the second fixed sleeves 56. The buffer assembly and the mounting mechanisms 45 work together to ensure that the battery compartment 1 mounted on the mounting mechanisms 45 is not only stably supported but also effectively protected from damage to the energy storage system of the battery compartment 1 caused by severe vibrations (such as the battery compartment 1 detaching from its installation position and causing damage to the entire device), enhancing the L 4507577 operational stability and energy storage efficiency of the battery compartment energy storage system, making it safer and more reliable with good usage effects. Additionally, when transporting the battery compartment, the mounting structure can be used for mounting on the transportation device, avoiding the impact of vibrations from the transportation device on the performance of the battery compartment.

This determines the required working duration for heat dissipation based on the heating status at critical points, the heat dissipation status of related parameters of the battery compartment, the ambient temperature, and the target working temperature of the battery, ensuring the calculation is reliable.
