Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically, it relates to a fire suppression device for lithium battery charging locations. Background Technology

[0002] With the widespread application of lithium batteries in electric vehicles, energy storage systems, and other fields, the number of lithium battery charging sites is increasing daily. However, lithium batteries pose a risk of thermal runaway during charging. Once thermal runaway occurs, it can easily cause a fire, which can spread rapidly and pose a great threat to life and property.

[0003] In the event of a fire, commonly used firefighting equipment includes dry powder extinguishers, carbon dioxide extinguishers, and water-based extinguishers. However, when dealing with fires in lithium battery charging areas and using dry powder extinguishers, strong winds can cause the dry powder to scatter, resulting in poor extinguishing effectiveness and making it difficult to effectively suppress the fire in the lithium battery charging area.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A fire suppression device for lithium battery charging sites includes support pillars and dry powder fire extinguishing equipment. Two support pillars are symmetrically arranged. An installation plate is fixed to the outer wall of one side of each support pillar. A conveying chamber is provided inside the installation plate. A conveying pipe is installed on the top of the installation plate and is connected to the dry powder fire extinguishing equipment. The conveying pipe is connected to the conveying chamber. Equally spaced branch pipes are installed at the bottom of the installation plate and are connected to the conveying chamber. Dry powder nozzles are installed at the bottom of the branch pipes and are connected to the branch pipes. Equally spaced guide covers are fixedly connected to the bottom outer wall of the installation plate. The branch pipes and dry powder nozzles are both located inside the guide covers.

[0007] In a preferred embodiment of this utility model, the bottom of the mounting plate is provided with equally spaced mounting holes, and the top end of the branch pipe is fixedly connected to the inner wall of the mounting holes.

[0008] In a preferred embodiment of this utility model, the outer wall of the opposite side of the support column is fixedly connected to the same mounting base, a charging pile is provided above the mounting base, and charging sockets are installed at equal intervals on one side of the mounting base.

[0009] In a preferred embodiment of this utility model, a rain shelter is fixedly provided at the top of the support column, and an inclined support rod is fixedly connected to the outer wall of one side of the support column, with the top of the support rod fixedly connected to the bottom outer wall of the rain shelter.

[0010] In a preferred embodiment of this utility model, a smoke sensor and an audible and visual alarm are fixedly installed on the outer wall of the bottom of the rain shelter, and the smoke sensor and the audible and visual alarm are connected by a signal line.

[0011] In a preferred embodiment of this utility model, the smoke sensor is connected to a controller via a signal line, and the audible and visual alarm is electrically connected to the controller.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention can respond immediately to a fire. When a fire occurs, the dry powder extinguishing device uses high-pressure gas and a delivery pipe to transport dry powder into the delivery chamber. The dry powder in the delivery chamber is then rapidly sprayed onto the fire source through branch pipes and dry powder nozzles, forming a covering layer at the fire source to isolate oxygen and inhibit combustion. The guide hood also guides the sprayed dry powder, preventing it from being blown away by the wind and thus effectively suppressing fires in lithium battery charging areas.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 4 As shown

[0023] A fire suppression device for lithium battery charging sites includes a support column 1 and a dry powder fire extinguishing device. The support column 1 has a common mounting base 13 fixedly connected to its opposite outer wall. A charging pile 12 is installed above the mounting base 13. Equidistantly distributed charging sockets 14 are installed on one side of the mounting base 13. Two support columns 1 are symmetrically arranged. A rain shelter 3 is fixedly installed at the top of each support column 1. An inclined support rod 4 is fixedly connected to one outer wall of each support column 1, with the top of the support rod 4 fixedly connected to the bottom outer wall of the rain shelter 3. A mounting plate 2 is fixed to one outer wall of each support column 1, and a [missing information - likely a device or equipment] is installed on the inner side of the mounting plate 2. The conveying chamber 9 has a conveying pipe 7 installed on the top of the mounting plate 2. The conveying pipe 7 is connected to the dry powder fire extinguishing equipment and is in communication with the conveying chamber 9. Equally spaced branch pipes 10 are installed at the bottom of the mounting plate 2. Equally spaced mounting holes are opened at the bottom of the mounting plate 2. The top of each branch pipe 10 is fixedly connected to the inner wall of the mounting hole and is in communication with the conveying chamber 9. A dry powder nozzle 11 is installed at the bottom of each branch pipe 10 and is in communication with the branch pipe 10. The dry powder fire extinguishing equipment conveys dry powder into the conveying chamber 9 through high-pressure gas and the conveying pipe 7. The dry powder in the delivery chamber 9 is rapidly sprayed to the fire source through the branch pipe 10 and the dry powder nozzle 11, forming a covering layer at the fire source to isolate oxygen and inhibit combustion. The bottom outer wall of the mounting plate 2 is fixedly connected with equidistantly distributed guide covers 8. The branch pipe 10 and the dry powder nozzle 11 are located inside the guide covers 8. The guide covers 8 guide the sprayed dry powder, preventing it from being blown away by the wind and thus effectively suppressing fires in lithium battery charging areas. The bottom outer wall of the rain shelter 3 is fixedly installed with a smoke sensor 5 and an audible and visual alarm 6. The smoke sensor 5 and the audible and visual alarm 6 are connected by a signal line. The smoke sensor 5 is connected to a controller through the signal line, and the audible and visual alarm 6 is electrically connected to the controller. When a fire occurs, the smoke sensor 5 receives the fire smoke signal and transmits the signal to the controller, which then activates the dry powder fire extinguishing equipment. At the same time, the audible and visual alarm 6 receives the signal from the smoke sensor 5 and sounds an alarm to alert people in the vicinity of the fire, allowing them to react promptly upon hearing the alarm.

[0024] The implementation principle of the fire suppression device in the lithium battery charging area of ​​this embodiment is as follows: In specific use, the delivery pipe 7 is connected to the external dry powder fire extinguishing equipment. When a fire occurs, the smoke sensor 5 receives the signal of the fire smoke and transmits the signal to the controller. The controller starts the dry powder fire extinguishing equipment to work, so that the dry powder fire extinguishing equipment delivers dry powder to the delivery chamber 9 through high-pressure gas and delivery pipe 7. The dry powder in the delivery chamber 9 is quickly sprayed to the fire source through the branch pipe 10 and dry powder nozzle 11, so that the dry powder forms a covering layer at the fire source, isolating oxygen and inhibiting the combustion reaction. At this time, the guide cover 8 can guide the sprayed dry powder to avoid the phenomenon of dry powder being blown around by the wind, so as to effectively suppress the fire in the lithium battery charging area. At the same time, the audible and visual alarm 6 receives the signal from the smoke sensor 5 and issues an alarm to remind the surrounding people that a fire has occurred, so that the surrounding people can react in time under the reminder of the alarm sound.
