Description

Technical Field

[0001] The invention belongs to small intelligent fire prevention equipment, and in particular relates to a battery water-cooled intelligent fire prevention device. Background Art

[0002] New energy vehicles, electric bicycles, and energy storage power stations all rely on battery charging for energy storage and driving. Common battery types include lead-acid batteries, lithium batteries (including lithium-ion and lithium polymer), etc. Different types of batteries have different charging requirements, such as battery power, suitable temperature, heat dissipation conditions, and safety factors. The existing battery charging method is to charge multiple batteries in parallel without gaps, resulting in heat accumulation between batteries during charging, and the temperature may rise to 30-50 degrees. Since the batteries of new energy vehicles and electric bicycles are all closed assemblies, there is no air cooling or ordinary liquid cooling device, resulting in local high temperature, which may trigger a chemical overheating reaction inside the battery, releasing a large amount of heat energy and combustible gas, thereby causing fire and explosion accidents. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the defects of the existing technology. The battery is placed in a battery waterproof heat dissipation box and then placed in the water tank through the reserved holes 5 / 6 of the water tank cover. The heat dissipation and cooling effect will be significantly improved. When there is water in the water tank and the battery is hot and smoking but there is no open flame, the water tank shell is equipped with a smoke alarm sensor. Through real-time monitoring, the water pump is automatically started in the first time to fill the battery with water, cool it down and turn off the flame.

[0004] The document (Guidelines for Emergency Response to Lithium Batteries on Board) officially implemented by the Civil Aviation Administration of China on March 1, 2018 clearly states that water fire extinguishing is the first choice. Dry powder fire extinguishing can only control external flames, while water can eliminate open flames, cool batteries, and prevent re-ignition.

[0005] The battery water-cooling intelligent fire prevention device of the present invention comprises a water tank, a water tank cover, a water inlet, a water outlet, a water pipe, a reserved hole, a battery waterproof heat dissipation box, a smoke alarm sensor and a water pump.

[0006] Further improvements include:

[0007] The battery water-cooling intelligent fire prevention device of the present invention includes a water tank, a battery waterproof heat dissipation box, a smoke alarm sensor, a water pump, etc., which are key components of the present invention. The reinforcing ribs around the water tank and the inner bottom box are injection-molded with polyethylene, which can prevent the water tank from deformation and stabilize the battery waterproof heat dissipation box. The battery waterproof heat dissipation box and the internal heat dissipation slot are die-casted by aluminum plates. The battery is placed in the battery waterproof heat dissipation box, and then 5 / 6 of it is placed in the water tank in the reserved hole of the water tank cover. A gap of 1cm-3cm is left between the battery waterproof heat dissipation box and the battery waterproof heat dissipation box according to user needs. For example, if the outdoor temperature is 35 degrees, the battery charging temperature is 20-40 degrees, and the water temperature is 25 degrees, water cooling can reduce the charging battery by 10-20 degrees to achieve the best battery use effect and extend the battery life, which can reduce the risk of fire by more than 90%.

[0008] Fires in electric bicycles occur when the batteries heat up and smoke during charging or driving, but no one notices or fire-fighting facilities are available, causing irreparable losses. The smoke alarm sensor installed on the water tank shell of this invention monitors in real time. When it detects that the battery is smoking but there is no open flame, it automatically starts the water pump to fill the battery's waterproof cooling box with water to cool the battery and extinguish the flames. As long as the source of the fire is discovered in the first time, a bowl of water can actually eliminate the fire hazard, protecting the property of the entire vehicle and reducing the risk of casualties.

[0009] The battery water-cooling intelligent fire prevention device of the present invention is novel and creatively dissipates heat and cools the battery through the water cooling principle. The design structure of the device is simple and reasonable. The water tank and the water tank cover are injection-molded by polyethylene, and the battery waterproof heat dissipation box is die-molded by lead plate. It is low in cost, easy to install and maintain, and can be mass-produced to meet market demand.

When the battery 11 is aging and smoking but there is no open flame, the smoke alarm sensor 3 installed on the outer shell of the water tank 1 automatically starts the water pump 4 through real-time monitoring to fill the battery waterproof heat dissipation box 9 with water, cools down the battery 11 and extinguishes the flames. The source of fire can be discovered at the first time at any time. In fact, a bowl of water can eliminate the fire hazard, thereby protecting the property of the entire vehicle and reducing the risk of casualties.
