Description

Technical Field

[0001] This invention relates to the field of battery energy storage cabinet technology, specifically a battery energy storage cabinet with a built-in automatic fire-fighting structure. Background Technology

[0002] Battery storage cabinets with built-in automatic fire suppression systems are important safety devices that can effectively prevent fires and protect the safety of the storage cabinet.

[0003] Currently, when fires occur in battery energy storage cabinets, most fire extinguishing agents are sprayed manually. However, the inability to react promptly when manually activating fire extinguishing equipment leads to further property damage. Furthermore, the inability to isolate the fire from the surrounding environment in time allows nearby battery packs to be affected and damaged. The large fire extinguishing area also results in a prolonged time to control the fire, further exacerbating the damage to the entire system. When the fire extinguishing agent runs out, the lack of timely replacement allows the controlled fire to reignite, increasing the difficulty of fire control. Summary of the Invention

[0050] The workflow of this invention is as follows: When using a battery energy storage cabinet with a built-in automatic fire suppression system, the device is first connected to the power supply to put it into operation. With both the smoke sensor 4 and temperature sensor 5 electrically connected to the controller 9 via wires, when the energy storage battery 12 reaches excessively high temperatures and smoke appears, the smoke sensor 4 and temperature sensor 5 detect the signal. With the drive motor 601 electrically connected to the controller 9 via wires, the drive motor 601 is activated, causing its drive end to rotate. The drive rod 602 is connected to the end of the energy storage cabinet body 1 via a bearing seat. On the surface, the drive rod 602 is rotated when connected to the bearing seat in a rotatable manner.

On the side wall of 9, the rotating rod 614 is connected to the bearing seat in a rotatable connection, which drives the rotating rod 614 to rotate. When the rotating rod 614 rotates, it drives the drive gear 615 to rotate. A fixed rack 616 is connected to the side wall of the drive gear 615. The fixed rack 616 is connected to the end face of the fixed square rod 608. The side wall of the movable box 609 is provided with a connecting hole corresponding to the fixed square rod 608. The fixed square rod 608 is connected to the connecting hole in a sliding connection, which drives the movable box 609 to move on the side wall of the fixed square rod 608, thereby delivering the smoke shielding fire extinguishing structure 7 to the corresponding position.

[0051] When the electric telescopic rod 701 is connected to the controller 9 via a wire in an electrical connection manner, the electric telescopic rod 701 is activated, causing its drive end to move downward. A groove is provided on the connecting slide rail 703 corresponding to the telescopic rack 702. The telescopic rack 702 is slidably connected to the groove, causing it to move downward. A rotating gear 704 meshes with the side wall of the telescopic rack 702. A rotating rod 705 is connected to the side wall of the connecting housing 700 via a bearing seat. The rotating rod 705 is rotatably connected to the bearing seat, causing the rotating gear 704 and the rotating rod 705 to rotate. When the rotating rod 705 rotates... When the cylindrical rotating wheel 706 and the driving worm gear 722 rotate, a V-shaped drive groove 707 is formed on the side wall of the cylindrical rotating wheel 706. A drive roller 708 is symmetrically connected inside the V-shaped drive groove 707. The V-shaped drive groove 707 and the drive roller 708 are fitted with a clearance fit.

The movable push rod 713 moves forward under the condition that the engagement method between the movable push rod 713 and the connecting hole is clearance fit. One end of the connecting rotating rod 715 is connected to the rotating shaft of the scissor-type telescopic frame 716. The scissor-type telescopic frame 716 is connected to the rotating shafts at both ends of the scissor-type telescopic frame 716.

When the rotating slider 717 and the groove are connected in a sliding connection, the scissor-type telescopic frame 716 is opened, which in turn drives the fireproof bellows cover 720 to open, covering the outside of the malfunctioning battery storage box 3. When the drive worm gear 722 rotates, a driven worm 723 is meshed on the side wall of the drive worm gear 722. The driven worm 723 is connected to the side wall of the fixed connecting plate 712 via a bearing seat.

When the electromagnetic control valve 813 is electrically connected to the controller 9 via a wire, the fire extinguisher 814 sprays extinguishing agent through the extinguishing agent nozzles on the extinguishing agent nozzle 724 onto the area above and below the abnormal battery storage box 3.

[0052] When the gravity sensor 816 is electrically connected to the controller 9 via a wire and detects that one of the fire extinguishers 814 has been used up, the servo motor 802, also electrically connected to the controller 9 via a wire, rotates. This causes the drive end of the servo motor 802 to rotate. The drive link 803, connected to the side wall of the fixed connecting plate 801 via a bearing seat, rotates. The other end of the drive link 803 is connected to the transmission bevel gear 805 via a rotating bevel gear 804, causing the transmission bevel gear 805 to rotate. The rotating link 806, connected to the side wall of the fixed connecting plate 801 via a bearing seat, rotates... When the connection between 06 and the bearing housing is a rotatable connection, it drives the rotating connecting rod 806 to rotate. When the rotating connecting rod 806 rotates, it drives the transmission gear 807 to rotate. A movable rack 808 is symmetrically connected to the side wall of the transmission gear 807. A groove is opened on the rack slide rail 809 corresponding to the movable rack 808. The movable rack 808 is slidably connected to the groove. A groove is opened on the slide rail 812 corresponding to the limiting slide rail 811. When the limiting slide rail 811 is slidably connected to the groove, it drives the left movable switch seat 810 to rise and the right movable switch seat 810 to fall and connect with the fire extinguisher 814, so as to continue the spraying of the extinguishing agent. At the same time, the other used fire extinguisher 814 is replaced manually.
