Detailed Description

As shown in fig. 1 and fig. 2, in this embodiment, the present invention includes at least two seawater main pipes 1 communicated with seawater, fire-fighting general pumps 2 communicated with the seawater main pipes 1 in a one-to-one correspondence, and pipeline systems 3 communicated with a plurality of the fire-fighting general pumps 2, wherein the plurality of seawater main pipes 1 are respectively disposed at the left and right ends of a cabin bottom, isolation valves 4 are disposed between the plurality of fire-fighting general pumps 2 and the pipeline systems 3, the number of the pipeline systems 3 is at least two, and any one of the pipeline systems 3 is communicated with a plurality of fire hydrants 5; in this design, the model of fire control general pump 2 selection is: the flow rate of the 65CWZ-6 type horizontal self-priming centrifugal water pump is 36m3/h, and the lift is 42 m. The fire-fighting general pump 2 is arranged in the mechanical equipment cabin and is positioned close to the submarine door, so that seawater in the submarine door can be conveniently pumped out to supply water for the fire hydrant 5 of the whole ship.

According to the scheme, the seawater main pipes 1 are respectively arranged at the left end and the right end of the bilge, so that the probability of simultaneous failure of the water supply system can be effectively reduced; when one fire-fighting general pump 2 breaks down, the other fire-fighting general pump 2 does not go to the fault water supply pipeline by closing the isolating valve 4 of the broken pipeline, and water supply is continued for fire extinguishing work.

One preferred scheme is, the water inlet department of sea water house steward 1 is equipped with a plurality of mesh grid 6 of coincide in proper order, a plurality of through-hole, adjacent two have all been seted up on mesh grid 6 the through-hole is the dislocation structure setting.

According to the scheme, the plurality of the mesh grids 6 are arranged at the seawater inlet end, and the through holes are arranged in a staggered structure, so that large-sized solid impurities in the sea can be effectively isolated.

Preferably, the isolation valve 4 adopts one or more combinations of one-way valves, mechanical valves or electromagnetic valves; in this design, a combination of one-way valves, mechanical valves and solenoid valves are used to control the opening and closing of the water supply lines.

One preferred scheme is that a plurality of fire hydrants 5 are respectively arranged at a propelling equipment hatch, a large living room, a battery cabin hatch, a ship head part, an upper deck and a top deck; in this design, two fire hydrants 5 are provided for each protection site to extinguish a fire at the highest speed after a fire accident occurs at the site.

One preferred scheme is that a detection pipeline 7 is arranged between the fire-fighting general pump 2 and the isolating valve 4, a water outlet of the detection pipeline 7 is arranged at the outer side end of the ship body, and a liquid flow meter 8 is arranged on the detection pipeline 7.

As can be seen from the above solution, the safety of the fire-fighting general pump 2 is further ensured by closing the isolation valve 4 and opening the detection pipeline 7, operating the fire-fighting general pump 2 and detecting the operation condition of the fire-fighting general pump 2 by combining the liquid flowmeter 8.

One preferred scheme is, pure electric power impels boats and ships's water fire extinguishing systems still includes a plurality of combustible gas detector, a plurality of smoke detector formula fire detector and a plurality of temperature sensing formula fire detector, a plurality of combustible gas detector, a plurality of smoke detector formula fire detector and a plurality of temperature sensing formula fire detector sets up respectively at propulsion equipment hatch, big sitting room, battery compartment hatch, bow portion, go up deck and top deck.
