The utility model discloses both can guarantee to share pond fire-fighting water absolutely not by other usefulness, can realize synthesizing again that water pump house life and production water pump and fire-fighting water pump arrange at same mark high level, coordinate unanimously, it is convenient to overhaul.
Description
Technical Field
The utility model belongs to the technical field of the fire-fighting water and specifically relates to a shared pond that fire-fighting water was not used.
Background
According to the technical Specification for fire hydrant systems and Water supply and fire hydrant systems GB50974-2014 No 4.3.8 mandatory provisions: the pool for sharing the fire-fighting water and other water needs to adopt a technical measure for ensuring that the fire-fighting water is not used for other purposes, and in the engineering design, the pool for sharing the fire-fighting water and other water is often adopted according to the conditions of water sources, sites and the like. Different types of water pumps of a shared water pool are generally arranged in a comprehensive pump room, and the fire-fighting water pump and the production and living water pump suction pipes are different in elevation to realize that fire-fighting water is not used by other users, so that the water suction pipes of the living and production water pumps are arranged on a fire water line of the shared water pool, but the problems of large height difference of the water pump foundation, uncoordinated water inlet and outlet pipelines, difficulty in maintenance and the like exist, and the difficulty in engineering realization is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a shared pool that fire-fighting water was not used is provided, both can guarantee that shared pool fire-fighting water is absolutely not by other usefulness, can realize synthesizing again that water pump house life and production water pump and fire-fighting water pump arrange at same mark high level, coordinate unanimously, it is convenient to overhaul.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the shared water pool comprises a shared water pool main body, wherein a living and production water line and a fire-fighting water line are arranged on the shared water pool main body, a living and production water pump and a fire-fighting water pump are respectively arranged in the shared water pool main body, water suction pipes of the living and production water pump and the fire-fighting water pump are arranged in the same standard layer, a cofferdam is arranged around the water suction pipe of the living and production water pump, the elevation of the top of the cofferdam is not lower than that of the fire-fighting water line, and the living and production water pump and the fire-fighting water pump are electrically connected with a DCS control system.
The utility model discloses technical scheme's further improvement lies in: the cofferdam is an overflow weir.
Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
the utility model discloses set up the overflow weir all around at life and production water pump suction pipe, even DCS control system is to life and production water pump control malfunctioning condition under, still can make shared pond fire-fighting water absolutely not by other usefulness, can realize synthesizing water pump room life and production water pump and fire-fighting water pump simultaneously again and arrange at same mark high level, coordinate unanimously, it is convenient to overhaul.
Drawings
FIG. 1 is a plan view of a shared pool of the present invention;
FIG. 2 is a sectional view of a shared pool according to the present invention;
wherein, 1, sharing the pool main body, 1-1, living and production water line, 1-2, fire water line, 2, living and production water pump, 3, fire water pump, 4 and cofferdam.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in fig. 1 to 2, the shared pool with no passive fire-fighting water supply comprises a shared pool main body 1, a living and production water line 1-1 and a fire water line 1-2 are arranged on the shared pool main body 1, a living and production water pump 2 and a fire water pump 3 are respectively arranged in the shared pool main body 1, water suction pipes of the living and production water pump 2 and the fire water pump 3 are arranged in the same standard high layer, a cofferdam 4 is arranged around the water suction pipe of the living and production water pump 2, the elevation of the top of the cofferdam 4 is not lower than that of the fire water line 1-2, the cofferdam 4 is an overflow weir, and the living and production water pump 2 and the fire water pump 3 are electrically connected with a DCS control system.
The utility model discloses set up behind cofferdam 4, the liquid level variation process is as follows in the shared pond main part 1: when the liquid level in the shared water pool main body 1 is reduced to reach the pump stop water level of the living and production water level line 1-1, the DCS control system sends a control signal to the living and production water pump 2, and the living and production water pump 2 stops pumping; if the DCS control system fails to control the living and production water pump 2, the liquid level in the shared pool main body 1 continuously drops to the elevation of the top of the cofferdam 4, the fire-fighting water in the shared pool main body 1 is separated by the cofferdam 4 and cannot enter the cofferdam 4, the water enclosed by the cofferdam 4 is quickly absorbed by the water absorption pipe of the living and production water pump 2, the water absorption pipe of the living and production water pump 2 is water-free and can be absorbed, and the living and production water pump 2 stops pumping. At this time, the water level in the shared pool main body 1 is maintained at the elevation of the top of the cofferdam 4 and is not lower than the fire water level line 1-2, so that the requirement that the fire water is not used for other purposes can be met.
