Description

[Technical Field]

[0001] This invention relates to a fire extinguishing system for initial fire extinguishing, and in particular to a fire extinguishing system consisting of a fire water tank using an electric submersible pump. [Background technology]

[0002] A fire water tank is a firefighting facility used to store water for use in firefighting activities in areas where water sources such as fire hydrants cannot be secured, and an engine-powered fire pump is used to supply water from the fire water tank. Summary of the Invention [Problem to be solved by the invention]

[0003] However, with engine-powered fire pumps, there are problems such as residents only receiving operation training once a year, and when they see the flames bursting forth in the event of a sudden fire, they lose their composure and are extremely difficult to start; they also produce noise and exhaust gases that have a negative impact on the environment; and they require refueling, which is a hazardous substance, making maintenance difficult. Therefore, there was a need for a simpler and more efficient means of supplying fire-fighting water, which would enable rapid response and initial fire extinguishing, and also improve operability, safety, and reduce environmental impact. [Means for solving the problem]

[0004] After careful consideration, the inventor solved the above problem by using an electric submersible pump instead of an engine-driven fire pump. That is, the present invention is a fire extinguishing system having the following configuration. [1] A fire extinguishing system for initial fire extinguishing, characterized by comprising a fire water tank and an electric submersible pump submerged in the water of the fire water tank. [2] A fire extinguishing system for initial fire extinguishing, characterized by comprising a fire water tank, an electric submersible pump submerged in the water of the fire water tank, and a battery for driving the submersible pump installed next to the tank. [3] The fire extinguishing equipment described in [1] or [2] above, characterized in that the fire water tank is installed on the ground or underground. [4] A fire extinguishing system according to any one of [1] to [3], characterized in that the fire extinguishing system is also equipped with an engine-driven fire pump. [Effects of the Invention]

[0005] This invention provides the following effects: (1) Initial firefighting response can be made faster. (2) It is easy to operate, and even residents can start it without any problems. (3) It is environmentally friendly as it does not produce noise or exhaust gases. (4) No need for regular refueling, making maintenance easy. (5) In this invention, when a submersible pump and a conventional engine-driven fire pump are installed side by side, even if a malfunction occurs in one of the pumps, even if the operator is unfamiliar with the operation, firefighting activities can be carried out reliably by immediately starting either pump. Furthermore, by operating both the submersible pump and the engine-powered fire pump simultaneously, the amount of water discharged can be doubled, significantly increasing the power of initial fire extinguishing. [Brief explanation of the drawings]

[0006] [Figure 1] This is an outline diagram of the application of this invention to a fire water tank installed on the ground. [Figure 2] This is an outline diagram of the application of this invention to a fire water tank installed underground. DETAILED DESCRIPTION OF THE INVENTION

[0007] The fire water tank in this invention has a capacity of 20 m 3 These are installed in residential areas, schools, public facilities, etc. Some are installed above ground and some are installed underground. This is ideal for early fire extinguishing, and is used to store water for use in firefighting activities in areas where water sources such as fire hydrants cannot be secured. In addition, the submersible pump used in this invention is electric, but the water discharge volume is 0.22 m 3 / min or more, and a water discharge pressure of 0.3 MPa or more is preferable. Submersible pumps require a power source, which may be a 100V AC power source, a 12V DC power source using a battery, or a 24V DC power source. A submersible pump is a device that submerges the pump body in water to pump up and discharge water. It does not require priming and is very quiet because the pump body is submerged in water. Its structure involves rotating an internal impeller to suck up water and discharge it to the desired location, and anyone can easily operate it by connecting a power source to the main unit. It is also preferable to add, i.e., install the above-mentioned submersible pump in addition to, a fire water tank equipped with a conventional engine-driven fire pump. In this case, even if one of the pumps has a malfunction, even an operator who is unfamiliar with the operation can immediately activate either pump and reliably carry out firefighting activities. Furthermore, by operating both the submersible pump and the engine-powered fire pump simultaneously, the amount of water discharged can be doubled, significantly increasing the power of initial fire extinguishing. [Example]

[0008] Example 1: An embodiment in which the present invention is applied to a fire protection water tank installed on the ground will be described with reference to FIG. That is, fire prevention water 1 is stored in a water tank 10 made of concrete or metal. A submersible pump 2 is installed inside the fire extinguishing tank, and water is pumped through a water pipe 3 into a fire extinguishing hose 3', which is then sprayed onto the fire scene from a fire extinguishing nozzle (not shown).

[0009] Example 2: An embodiment in which the present invention is applied to a fire protection water tank installed underground will be described with reference to FIG. Fire prevention water 1 is stored in a concrete water tank 10' installed underground. A submersible pump 2 is installed inside the fire extinguishing tank, and water is pumped through a water pipe 3 into a fire extinguishing hose 3', which is then sprayed onto the fire scene from a fire extinguishing nozzle (not shown). In addition, 4 is a battery, 41 is an electric wire, 5 is a fire water tank slab, and 6 is a manhole. In this example, the capacity of the tank is 50m 3 The specifications of the submersible pump are shown in Table 1. By installing an electric submersible pump with a discharge rate of 500 liters per minute, water can be released instantly by simply operating a switch in the event of a fire.
