Abstract

PROBLEM TO BE SOLVED: To make it possible to use a total amount of water stored in these water tanks concentratedly at one location by providing separately a large number of fire preventive water tanks with a proper spacing and communicating each of the water tanks with a communication pipeline. SOLUTION: A large number of fire preventive water tanks are dispersedly provided with a proper spacing in a wide area so that they may be placed basically at the same level. Each of the fire preventive water tanks 1 is set up respectively so as to comply with some unevenness of specified geographical features. More particularly some should be provided completely underground while the other should be partially exposed to the ground. A large number of fire preventive water tanks 1 are communicated with each other by way of communication pipelines 2 basically at the lowest water level. This construction makes it possible to maintain many fire preventive water tanks completely at the same water storage level and supply water to the specific tank in automatic mode even if water is pumped up from any fire preventive water tank located at any place and feed water concentratedly at one location.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire protection water tank for storing fire protection water, and more particularly to a fire protection water tank multiple system capable of effectively utilizing the water storage of a large number of fire protection water tanks arranged at appropriate intervals over a wide area.

[0002]

2. Description of the Related Art As is well known, in an urbanized area, a fire tank having a capacity larger than a specified amount is provided for each specified area of the area. Facilities are provided to supply water to the area in charge. Since the range in which water can be supplied is limited by the pump capacity and hose length of the fire engine, a large number of fire prevention water tanks are provided at appropriate intervals based on the water supply capacity.

[0003]

When a large fire occurs in a certain area and a large amount of water for digestion is required intensively, one or several fire prevention water tanks provided in the area are stored. It can be used up quickly. In such a case, multiple fire pumps and hoses may be connected to supply water from fire tanks in distant areas, but this would take considerable time and effort, and there was a problem that it was not possible to respond immediately to an emergency. .

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to collectively store the total amount of water stored in a large number of fire prevention water tanks arranged at appropriate intervals over a wide area. An object of the present invention is to provide a fire prevention water tank multiple system that can be pumped and used.

[0005]

The fire protection water tank multiple system according to the present invention has, as a basic system configuration, a large number of fire protection water tanks distributed over a wide area at appropriate intervals so as to have substantially the same horizontal level. At the same time, these fire prevention water tanks are mutually connected by a communication pipe.

[0006] Further, when the above-mentioned multiple fire prevention water tank multiple systems provided in an area of a certain horizontal level is a first group, and the above-mentioned multiple fire prevention water tank multiple systems provided in another area with a low horizontal level is a second group. A system configuration connected by a water supply pipe provided with a water supply control valve for supplying water from a first group in a high region to a second group in a low region,
It is possible to develop a system configuration with a pump for supplying water from the second group in the lower area to the first group in the higher area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A schematic configuration of a fire water tank multiple system according to one embodiment of the present invention is shown in a plan view of FIG. 1 and a sectional view of FIG. In urban areas with almost flat terrain, a large number of fire tanks 1,
Are provided dispersed over a wide area at appropriate intervals. Generally, the upper end of each fire prevention water tank 1 is provided at the ground level GL. However, depending on the slight unevenness of the terrain, the fire prevention water tanks 1 may be provided completely underground or partially exposed above the ground. A water tank 1 is installed.

Further, a large number of fire prevention water tanks 1, 1,... Are communicated with each other by communication pipes 2, 2,. In the layout of the embodiment of FIG. 1, a large number of communicating pipes 2, 2,... Are arranged in a grid pattern, and a fire prevention water tank 1 is arranged at the intersection of the communicating pipes 2. With this configuration, the water storage levels of a large number of fire protection water tanks 1, 1,... Are all kept equal, and even if water is pumped from any one of the fire protection water tanks 1, the other fire protection water tank groups 1 are directed toward the specific fire protection water tank 1. , 1, ... are automatically supplied with water, and these fire prevention water tank groups 1, 1, ...
Can be used intensively at one location.

[0009]

According to the present invention, a large number of fire prevention water tanks are provided in a wide area at appropriate intervals so as to have substantially the same horizontal level, and these fire prevention water tanks are mutually connected by a communication pipe. Therefore, a large number of fire prevention tanks function as if they are one tank, and water is automatically supplied from other fire prevention tank groups to the specific fire prevention tank regardless of where the water is pumped from the fire prevention tank. In addition, the total water storage of these fire prevention water tank groups can be intensively used at one location. Therefore, even if a large fire occurs in a certain area and a large amount of digestion water is required intensively, it can be responded immediately.

In addition, a system configuration in which water stored in a first group in a high region is connected to a water supply pipe having a water supply control valve for supplying water to a second group in a low region, and water storage in a second group in a low region is high. The development of a system configuration with a pump for supplying water to the first group in the region will be more effective in increasing the flexibility of storing water.
