Description

Technical Field

[0001] The utility model relates to a fire-fighting facility, in particular to a fire-fighting device used for an electric bicycle parking shed. Background Art

[0002] As the number of electric bicycles increases, electric bicycle fire accidents are also increasing. The "Regulations on Fire Safety Management of High-rise Civil Buildings" clearly prohibits parking or charging electric bicycles in public foyers, evacuation corridors, stairwells, and emergency exits of high-rise civil buildings. Therefore, the transformation of electric bicycle parking and charging sheds in residential areas or public places has become a major event that benefits the country and the people. However, if electric bicycles are parked in a shed and one of them catches fire, if it is not discovered in time, there is a high possibility of a "camp-wide fire" and even endangering the safety of nearby residents.

[0003] The existing fire-fighting measures for electric bicycle sheds are as follows: First, place fire extinguishers and set up surveillance cameras, but since most electric bicycle fires are caused by lithium batteries, when the fire is discovered, it is too late for personnel to rush to the fire scene, so this fire-fighting measure is not very meaningful; the second measure is to set up automatic smoke detection and introduce automatic spraying of fire water, but this cannot detect lithium battery fires in time, and ordinary fire water cannot completely and quickly extinguish lithium battery fires, and can only play a cooling role, wasting water. The third method is to combine water spray fire extinguishing methods with synthetic foam spray fire extinguishing methods, but this fire extinguishing method requires the use of high-pressure fire water, and for the renovated electric bicycle parking shed, fire water is difficult to achieve.

[0004] Chinese patent CN 218010710 U discloses a fire prevention and control system for electric bicycle charging stations. The foam atomization fire extinguishing device consists of a booster water pump connected to a tap water pipe, a foam fire extinguishing agent and a 1m3 water supply tank. The tap water pipe, the water supply tank and the foam fire extinguishing agent are connected to the water inlet of the booster water pump, and the foam delivery pipeline is connected to the water outlet of the booster water pump. After adopting the above scheme, the water flow of the booster pump is supplemented by the water tank on the tap water waterway to meet the water volume and water pressure requirements of 8 wide-angle atomizing nozzles working at the same time, so as to achieve full flooding fire extinguishing of the fire control zone and extinguish the fire in a small area. This scheme adopts a water supply tank and a zoned fire extinguishing, and does not need fire water, but the problem is that this scheme requires the independent setting of water tanks and fire fighting hosts, which is costly; at the same time, for the low temperature environment in winter in northern regions, the water tanks and fire fighting hosts set outdoors are easy to freeze and cannot work. Utility Model Content

[0005] The utility model aims to provide a low-cost, moisturizing electric bicycle shed fire host

[0006] To achieve the above-mentioned purpose, the utility model provides an electric carport fire-fighting main unit, comprising a water tank, a booster water pump and a foam fire extinguishing agent, the water tank being connected to a water inlet pipe, wherein the booster water pump and a sealed foam fire extinguishing agent tank are arranged in the water tank, the water inlet of the booster water pump is arranged at the bottom of the water tank, the delivery pipeline of the foam fire extinguishing agent is connected to the negative pressure pipe of the booster water pump, and an electromagnetic switch is arranged in the delivery pipeline of the foam fire extinguishing agent; the water outlet of the booster water pump is connected to the fire-fighting pipeline, the capacity of the water tank is the number of nozzles controlling the spraying*flow rate / nozzle*spraying time; an insulation layer is arranged on the outside of the water tank.

[0007] An electric heating device and a temperature sensing probe are arranged in the water tank.

[0008] A liquid level sensor is provided in the water tank.

[0009] After adopting the above scheme, the booster pump and foam fire extinguishing agent are set in the water tank instead of a separate fire fighting host, which saves medicine costs and is suitable for fire fighting renovation of electric bicycle sheds. In addition, an insulation layer is set on the outside of the water tank for easy use in northern winter. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0014] See also Figure 1The utility model is a fire-fighting host of an electric shed, comprising a water tank 1, a booster water pump 2, a foam fire-extinguishing agent tank 3 and a host control system 8. The water tank 1 is connected to tap water, and the water inlet is controlled by a liquid level sensor 6 arranged in the water tank 1. The volume of the water tank is the number of nozzles for controlling spraying*flow / nozzle*spraying time, which is generally 1 ton or 500 kilograms. The booster water pump 2 and the foam fire-extinguishing agent tank 3 are arranged in the water tank 1, and the water inlet of the booster water pump 2 is arranged at the bottom of the water tank 1. The foam fire-extinguishing agent delivery pipeline 32 of the foam fire-extinguishing agent tank 3 is connected to the negative pressure pipe 22 of the booster water pump 2. The foam fire-extinguishing agent tank 3 is provided with an air supply pipe 31 connected to the outside of the water tank, and an electromagnetic switch is arranged in the foam fire-extinguishing agent delivery pipeline 32 (not shown in the figure, the purpose is that the foam fire-extinguishing agent will not enter the water tank in the non-working state to cause the agent to deteriorate and corrode); the water outlet 21 of the booster water pump 2 is connected to the fire-fighting pipeline of the electric shed, and the host control system 8 is connected to the entire fire control system through the control harness 7. To prevent freezing, an insulation layer 9 is provided on the outside of the water tank 1, and an electric heating device (such as an electric heating rod 4) and a temperature sensor 5 are also provided inside the water tank 1 to ensure that the outdoors will not freeze and damage the main unit and pipelines in the cold winter in the north.
