The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to specify further.
Referring to Fig. 2; On scheming, can find out; A kind of outdoor fire hydrant system of anti-secondary pollution; Comprise outdoor fire hydrant 10, on said outdoor fire hydrant 10, be connected with spray irrigation system 18, said spray irrigation system 18 is used for municipal grid 17 is transported to the position that afforestation of city need be sprayed to the stagnant water in the connection pipeline between the said outdoor fire hydrant 10.Be connected with spray irrigation system 18 on the outdoor fire hydrant 10, can effectively improve the water body exchange of stagnant water section, improve the concentration of disinfectant, reduce the generation of stagnant water as much as possible, avoid the secondary pollution of stagnant water as much as possible, ensure water supply quality the municipal administration pipe network of rivers.
Said spray irrigation system 18 comprises backflow preventer 11, hand sluice valve 20, electromagnetic valve 12 and the rainer 13 of series connection successively, also comprises the automatic control system 14 that control electromagnetic valve 12 is opened or closed that is used for that is connected with said electromagnetic valve 12; Said rainer 13 is arranged on the position that said afforestation of city need be sprayed; Said backflow preventer 11 is connected with said outdoor fire hydrant 10.
Hand sluice valve 20 generally is in opening, only under following two kinds of situation, just can close.First kind of situation, when fire-fighting needs water, and automatic control system 14 uncontrollable electromagnetic valves 12 stop sprinkling irrigation through cutting out hand sluice valve 20 when cutting out, and ensure water for fire; Second kind of situation when needs overhaul irrigation system 18, smoothly, closed hand sluice valve 20 for guaranteeing maintenance.
Automatic control system 14 is controlled application rate of sprinkler irrigation through size and the opening time of controlling said electromagnetic valve 12 unlatchings.
Said automatic control system 14 comprises that signal receives transmitter 15 and remote automatic control device; Said signal receives transmitter 15 and is electrically connected with said electromagnetic valve 12, and said signal receives transmitter 15 and is connected with said remote automatic control device radio communication.
Remote automatic control device sends a signal of opening electromagnetic valve 12, after signal reception transmitter 15 receives this signal, opens electromagnetic valve 12, the signal of return solenoid valve 12 unlatchings simultaneously or closed condition;
Remote automatic control device sends a signal of closing electromagnetic valve 12, after signal reception transmitter 15 receives this signal, closes electromagnetic valve 12, the signal of return solenoid valve 12 unlatchings simultaneously or closed condition.
Said remote automatic control device comprises the remote computer 21 and long-range hand-held mobile terminal 19 that is arranged at the control room.Usually with the remote computer that is arranged at the control room as main remote automatic control device, long-range hand-held mobile terminal is as the aided remote automaton.
A said spray irrigation system 18 can be connected with one or more outdoor fire hydrants 10.According to outdoor fire hydrant 10 arrangement pitchs, next spray irrigation system 18 of normal conditions can be connected with 5 outdoor fire hydrants 10 at most simultaneously.
On the said rainer 13 a plurality of sprinkling irrigation shower nozzles can be installed as required, next rainer 13 of normal conditions can be installed 10 shower nozzles at most simultaneously.
Embodiment: as shown in Figure 3; Adopt SS100/65-1.0 type ground type outdoor fire hydrant; Three mouthfuls of flanges that flange adapter 4 changed into three interfaces are taken over, and the backflow preventer of taking over spray irrigation system 18 through three mouthfuls of flanges 11 links together with outdoor fire hydrant 10, and these three mouthfuls of flanges adapters are positioned at underground; So neither road occupying also is difficult for being damaged.Backflow preventer 11, hand sluice valve 20, electromagnetic valve 12 and rainer 13 are connected successively; Signal receives transmitter 15 and is electrically connected with electromagnetic valve 12, and the remote computer that is arranged at the control room receives transmitter 15 radio communications with long-range hand-held mobile terminal and signal and is connected.
When needs were sprayed, remote computer 21 or long-range hand-held mobile terminal 19 sent a signal of opening electromagnetic valve 12, after signal reception transmitter 15 receives this signal, opened electromagnetic valve 12, the signal of return solenoid valve 12 unlatchings simultaneously or closed condition; When sprinkling irrigation finished, remote computer 21 or long-range hand-held mobile terminal 19 sent a signal of closing electromagnetic valve 12, after signal reception transmitter 15 receives this signal, closed electromagnetic valve 12, the signal of return solenoid valve 12 unlatchings simultaneously or closed condition.
At this moment, water advanced gate valve 16 through municipal grid 17 and flow to Outdoor Fire Hydrant 10, again through backflow preventer 11, hand sluice valve 20 and electromagnetic valve 12, at last through rainer 13 position that afforestation of city need spray of spraying.
When fire-fighting needed water, remote computer 21 or long-range hand-held mobile terminal 19 sent a signal of closing electromagnetic valve 12, after signal reception transmitter 15 receives this signal, closed electromagnetic valve 12, the signal of return solenoid valve 12 unlatchings simultaneously or closed condition.Break down to close electromagnetic valve 12 time when remote computer 21 and long-range hand-held mobile terminal 19 occurring, can stop sprinkling irrigation, ensure water for fire through closing hand sluice valve 20.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
