Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing devices, and in particular to a fire prevention and extinguishing device for a charging vehicle. Background Technology

[0002] AGV (Automated Guided Vehicle) is widely used in the warehousing and logistics industry for transporting goods. Currently, AGVs on the market are typically powered by lithium batteries, which have a limited range and require recharging after reaching their limit. However, AGVs are usually charged together in a concentrated manner. Lithium batteries also pose a risk of combustion and explosion after prolonged use. Therefore, when a large number of AGVs are charged together, an accident in one AGV can ignite surrounding AGVs, potentially causing a chain reaction of fires. Therefore, our company previously applied for a patent, application number: 202420978423.X, for an AGV charging fire prevention and extinguishing device, including a base (1), a vertically movable fireproof cover (2), and a drive mechanism. A drive assembly (3) for vertically moving a fireproof cover (2), the fireproof cover (2) being positioned above the trolley, the side wall of the fireproof cover (2) being provided with a clearance groove (21) for the trolley to connect to the charging pile for charging, the drive assembly (3) driving the fireproof cover (2) to rise so that a gap is formed between the bottom of the fireproof cover (2) and the ground for the trolley to enter and exit; the fireproof cover (2) descending to cover the trolley located at the charging position.

[0003] However, the aforementioned AGV charging fire prevention and extinguishing device has a drawback: the fireproof cover has limited application and is not suitable for some taller AGVs. Therefore, our company has developed a second-generation product for upgrade. Utility Model Content

[0017] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0018] This application discloses a fire prevention and extinguishing device for a charging vehicle, including a base 1 and a fireproof cover 2 mounted on the base 1. The fireproof cover 2 includes a fixing plate 21, a flexible fireproof sleeve 22, and a lifting frame 23. The flexible fireproof sleeve 22 is made of Class A fireproof cloth. The fixing plate 21 is fixedly mounted above the base 1. The lifting frame 23 is U-shaped, and its two ends are connected to the side wall of the base 1 via guide rails 7, which extend vertically and are fixedly mounted on the side wall of the base 1. One end of the flexible fireproof sleeve 22 is connected to the fixing plate 21, and the other end is connected to the lifting frame 23. The lifting frame 23 is located below the fixing plate 21. A drive mechanism 3 is provided on the base 1 to drive the lifting frame 23 to slide vertically. Under normal circumstances, when the vehicle does not spontaneously combust, the entire fireproof cover 2 is in an open state, with the lifting frame 23 positioned above and close to the fixing plate 21. The fireproof cover 2 is in a folded state, thereby reducing the space occupied by the fireproof cover 2 to accommodate more vehicles and expand its application range.

[0019] The flexible fireproof sleeve 22 has through holes on the side facing the base 1 for charging equipment such as wires to pass through. This prevents the flexible fireproof sleeve 22 from touching the trolley or its charging equipment as it moves down with the lifting frame 23, reducing the possibility that the fireproof sleeve 2 may not fully descend to the bottom in the event of spontaneous combustion of the trolley. The base 1 is installed against the wall. When the lifting frame 23 descends to the bottom, the cooperation between the fireproof sleeve 2, the base 1, and the wall will keep the trolley in a closed space.

[0020] The flexible fireproof sleeve 22 is provided with several folded plates 24 spaced vertically. The flexible fireproof sleeve 22 between two adjacent folded plates 24 has an inwardly recessed crease 5. When the fireproof cover 2 is in the folded state, the two adjacent folded plates 24 are close to each other, and the flexible fireproof sleeve 22 between the two adjacent folded plates 24 is folded inward and located between the two folded plates 24. The design of the folded plates 24 and the crease 5 allows the flexible fireproof sleeve 22 to automatically fold when the lifting frame 23 rises, and the folding is more regular, similar to a corrugated pipe.

[0021] The flexible fireproof sleeve 22 is folded to form a slot 4, and the folded plate 24 is inserted into the slot 4 and fixed with glue.

[0022] The drive mechanism 3 includes a winch 31 with a wire rope 316 wound around it and guide wheels 32. The guide wheels 32 are mounted on a fixed plate 21. The free end of the wire rope 316 passes through the guide wheels 32 and is fixedly connected to the lifting frame 23. The wire rope 316 has four strands, and the free ends of the four strands are fixedly connected to the four corners of the lifting frame 23 respectively. The four strands of wire rope 316 are gathered and wound onto the winch 31 by eight guide wheels 32. The winch 31 is mounted inside a base 1, and the base 1 has a through groove 6 for the wire rope 316 to pass through. The use of four strands of wire rope 316 makes the lifting frame 23 more stable when moving up and down. Of course, a hydraulic cylinder, electric cylinder, or pneumatic cylinder can also be used for drive.

[0023] The winch 31 includes a bracket 311, a take-up roller 312, and a drive motor 313. The bracket 311 is fixedly installed in the base 1, and the take-up roller 312 is rotatably mounted on the bracket 311. The drive motor 313 is fixedly installed on the bracket 311 and is linked with the take-up roller 312. Three partitions 314 are spaced apart on the take-up roller 312. The partitions 314 and the bracket 311 divide the take-up roller 312 into four take-up zones 315. Each take-up zone 315 has a strand of wire rope 316 wound in it, so that the four strands of wire rope 316 are not easily tangled together.

[0024] An automatic fire extinguishing device is also provided on the base 1. The automatic fire extinguishing device includes a smoke detector, a temperature detector and a fire extinguisher. The specific structure of the automatic fire extinguishing device has been disclosed in the patent application number: 202420978423.X, and will not be described in detail here.

[0025] Alternatively, a separate button can be provided to control the activation of the automatic fire extinguishing system and winch 31. With this separate button, the automatic fire extinguishing system and winch 31 can be manually activated in the event of a malfunction of the smoke detector or temperature detector.

[0026] The implementation principle of the fire prevention and extinguishing device for a charging vehicle in this embodiment is as follows: When the vehicle does not spontaneously combust, the lifting frame 23 is always in the highest position, the folding plates 24 are close together, and the flexible fireproof sleeve 22 between two adjacent folding plates 24 is folded inward and located between the two folding plates 24, so that the entire fireproof cover 2 is in a folded and retracted state, reducing the space occupied and accommodating more vehicles of different heights; when the vehicle spontaneously combusts, the automatic fire extinguishing device will work, and at the same time the winch 31 will unwind the steel wire rope 316, and the lifting frame 23 will move down to the ground under its own gravity. The flexible fireproof sleeve 22 will extend during this process, and the entire fireproof cover 2 will cover the spontaneously combusting vehicle. The automatic fire extinguishing device will extinguish the fire inside the fireproof cover 2, thereby achieving fire prevention and extinguishing work and making it less likely to ignite surrounding vehicles charging together.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
