Further, the fire pump is two.
Further, the fire pump with be equipped with cyclic annular pipe network between the trunk line, cyclic annular pipe network be equipped with two with the water supply pipe that the trunk line is connected.
Furthermore, the fire-fighting water pool and the fire-fighting water pump are uniformly distributed at the safety exit of the underground station hall.
Further, still include water pump adapter, water pump adapter passes through the pipeline and is connected with the main pipeline, water pump adapter sets up outside the underground station room.
Further, the fire pool is provided with a water intake, and the distance between the water pump adapter and the water intake is 15-40 meters.
The utility model has the advantages that: the utility model discloses with one set of fire extinguishing systems of outdoor fire hydrant and indoor fire hydrant sharing, solved the outdoor fire hydrant water supply problem of many entrances underground station, owing to one set of system of sharing, saved the investment, simplified control system, make more accurate quick response of control system, and when putting out a fire, lacked this process of outdoor water input indoor, put out a fire more high-efficient safety.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
shown in the figure: the fire-fighting water pool comprises a fire-fighting water pump 1, a fire-fighting water pump 2, a main pipeline 3, an underground station hall 4, an access opening 5, an indoor fire hydrant 6, an outdoor fire hydrant 7, a water pump adapter 8, a water supply pipeline 9, an annular pipe network 10, a water intake 11 and a connecting pipe 12.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, the utility model discloses a fire hydrant system structure suitable for many entrances and exits underground station, including fire-fighting water pump 2, fire-fighting water pool 1 trunk line 3 and underground station room 4, underground station room 4 is equipped with a plurality of access & exit 5, a plurality of indoor fire hydrants 6 have been arranged in underground station room 5, access & exit 5 is equipped with outdoor fire hydrant 7, 3 end to end of trunk line are the annular and arrange in underground station room 4, indoor fire hydrant 6 with outdoor fire hydrant 7 all connects in parallel through connecting pipe 12 on the trunk line 3, 2 one end of fire-fighting water pump with fire-fighting water pool 1 connects, one end with trunk line 3 connects.
Wherein, the fire pump 2 is preferred two, and one can be used as the reserve pump.
It can be understood that the design flow Q of the waterproof pump 2 is equal to the design flow Q of the indoor fire hydrant1(ii) a The design lift H of the fire pump meets the pressure H required by the most unfavorable fire hydrant at the inlet and the outlet1(ii) a The effective volume V required by the fire pool is equal to the water quantity V required by the outdoor fire hydrant for fire fighting1The water quantity V required by the indoor fire hydrant for fire fighting2Sum, i.e. V ═ V1+V2。
When the indoor conflagration that breaks out, fire-fighting water pump 2 starts, draws water from fire-fighting pool 1, and rivers reach indoor fire hydrant 6 through trunk line 3, and indoor fire hydrant 6 puts out a fire after opening, and the water consumption is totally spent in being suppressed or fire-fighting pool 1 until the conflagration. When needs use outdoor fire hydrant to put out a fire, fire-fighting water pump 2 starts, draws water from fire-fighting water pool 1, and rivers reach outdoor fire hydrant 7 through trunk line 3 and connecting pipe 12, put out a fire after outdoor fire hydrant 7 is opened, and the water consumption is totally used up in the time of the conflagration is suppressed or fire-fighting water pool 5. Wherein, the indoor fire hydrant 6 and the outdoor fire hydrant 7 can be used simultaneously, and the principle is the same. The outdoor fire hydrant of the fire hydrant system structure can only be used for fire extinguishing and cannot be used for water taking of a fire engine because water is supplied by the fire pump 2. The utility model discloses with one set of fire extinguishing systems of outdoor fire hydrant 7 and indoor fire hydrant 6 sharing, solved the indoor outer fire hydrant water supply problem of many entrances underground station, owing to one set of system of sharing, saved the investment, simplified control system, made control system accurate quick response more, and when putting out a fire reduced this process with outdoor water input indoor, put out a fire more high-efficient safety.
The embodiment of the utility model provides an in, be equipped with cyclic annular pipe network 10 between fire-fighting water pump 2 and the trunk line 3, cyclic annular pipe network 10 is equipped with two water supply pipe 9 of being connected with trunk line 3. So, damage when one in two fire control water pumps and can not supply water under the condition, the rivers that another water pump was gone into are full of cyclic annular pipe network 10 earlier after, get into trunk line 3 through two water supply pipe 9 again, so can prevent rivers from detouring in trunk line 3, can reduce system response time.
The utility model discloses an in one of them embodiment, 4 safe exits in the underground station room are arranged in to fire-fighting pond 1 and fire-fighting water pump 2 equipartition. Therefore, the influence on the whole fire fighting system during station fire can be reduced.
In order to prevent that the water pump can not supply water or fire-fighting pool water consumption after totally, entire system became invalid, the utility model discloses still including water pump adapter 8, water pump adapter 8 passes through the pipeline and is connected with trunk line 3, and water pump adapter 8 sets up outside the underground station room 4. This allows water to be supplied to the hydrant by the water pump adapter.
The embodiment of the utility model provides an in, fire pond 1 is equipped with intake 11, and the distance of water pump adapter 8 and intake 11 is 15 ~ 40 meters. Thus, the fire engine can supply water to the main pipe 3 through the water pump adapter 8 after taking water from the water intake 11. So can damage or the unable time supplying water of water pump when the water pump, the fire engine can follow 1 water intaking of fire-fighting water pond and supply water to trunk line 3.
