Referring to Fig. 1, this kind of structural schematic diagram of strong and weak electricity boxcar provided by the utility model.
Referring to Fig. 2, an a kind of circuit diagram of strong and weak electricity boxcar work provided by the utility model.
Referring to Fig. 3, a kind of another circuit diagram of strong and weak electricity boxcar work provided by the utility model.
The utility model provides a kind of one embodiment of strong and weak electricity boxcar, is arranged indoors, including：Strong and weak electricity turns
Change the mold relay 200 in block 100 and box.
Strong and weak electricity conversion module 100 includes forceful electric power terminal and light current terminal, and forceful electric power terminal is exchanged with the 220V in distribution box
Power supply connection.
Strong and weak electricity conversion module 100 is used to be converted to the 220V AC voltage signal of forceful electric power terminal the 24V of light current terminal
D. c. voltage signal.
String electrical phenomena occurs at the first relay 500 in order to prevent, so the utility model is by 220V AC voltage signal
Be converted to 24V d. c. voltage signal.
The coil of relay 200 in box, light current terminal, in distribution box the second relay 300 normally opened contact and fire resisting damper
The normally opened contact of the first relay 500 is connected in the first loop in executing agency.
The normally opened contact of relay 200 is connected in the control loop of firefighting fan 400 in box.
It is understood that the control loop of firefighting fan 400 includes 220V AC power source, relay 200 is normal in box
The function that contact plays switch in the control loop of firefighting fan 400 is opened, after the normally opened contact closure of relay 200 in box,
The control loop of firefighting fan 400 can be connected.
The coil of first relay 500 is connected in the control loop of fire resisting damper, and issues 24V fire resisting damper in fire-fighting system
It is obtained after control signal electric.
After fire-fighting system issues fire-fighting signal, the coil of the second relay 300 obtains electric.
It should be noted that the coil of the second relay 300 electric must belong to existing skill after anti-system issues fire-fighting signal
Art, it is not described here in detail.
In the present embodiment, as shown in figure 3, after fire occurs, in fire-fighting system, fire-fighting controls the fire resisting damper control of host
Molding block first issues the fire prevention valve control signal of 24V to the first relay 500, the coil of the first relay 500 obtain it is electric so that
The normally opened contact of one relay 500 is closed；Also, in addition fire-fighting system can also issue fire-fighting signal to the second relay 300, make
The second relay 300 coil obtain it is electric, then the normally opened contact of the second relay 300 can be also closed；So that first time
Road is connected, and the coil of relay 200 obtains electric in box, so that the normally opened contact of relay 200 is closed in box, firefighting fan
400 control loop conducting, firefighting fan 400 work.
It should be noted that the control loop of the firefighting fan 400 at 200 normally opened contact both ends of relay does not embody in box
In Fig. 3；In addition, in Fig. 3, the connection relationship of firefighting fan 400 and the first relay 500 belongs to physical connection, therefore
In practical application, the first relay 500 and firefighting fan 400 are physical connection and roof or the periphery that building is arranged in；In Fig. 3
In, the first terminals 1 and the second terminals 2 of the first relay 500 are coil both ends, third terminals 3 and the 4th terminals 5
For normally opened contact both ends.
Since after the fire resisting damper control module of fire-fighting control host first issues the fire prevention valve control signal of 24V, fire resisting damper meeting
It first opens, correspondingly, is connected after the control loop of firefighting fan 400, so the ability work after fire resisting damper opening of firefighting fan 400
Make, meets the requirement that fire resisting damper and firefighting fan 400 successively link in fire-fighting system.
In addition, managing interior temperature there are a fusing mechanism in fire-fighting domain when firefighting fan 400 and reaching certain temperature
Afterwards, fire resisting damper will fuse automatically, thus cause 500 open circuit of the first relay, so that firefighting fan 400 stops working, with
Avoid fire spreading；In the present invention, after fire resisting damper fuses automatically causes the first 500 open circuit of relay, relay in box
The normally opened contact of device 200 will be opened because of power loss, so that firefighting fan 400 stops working, therefore the utility model is strong
Light current boxcar enables firefighting fan 400 to be blown mechanism control.
The utility model completes the separation of strong and weak electricity in strong and weak electricity boxcar, and the coil of the first relay 500 and
Normally opened contact is by 24V DC-voltage supply, so string electricity will not occur the first relay 500 is easy to be influenced by weather
Phenomenon；On this basis, because the first relay 500 is original in fireproof valve executing mechanism, the second relay 300 is distribution box
In it is original, therefore the utility model haves no need to change original device, and improvement cost is low.
Further, the quantity of relay 200 is multiple and is connected in parallel on light current terminal in box；In box relay 200 with
Firefighting fan 400 corresponds.
It is understood that relay 200 is for controlling a firefighting fan 400 in a box, to realize one
Strong and weak electricity boxcar controls multiple firefighting fans 400.
Further, it is provided with indicator light on relay 200 in box, is used to indicate leading for 400 control loop of firefighting fan
Logical state.
It is understood that the setting of strong and weak electricity boxcar is indoors, and firefighting fan 400 is arranged in outdoor, so needing
Indicator light indicates the on state of 400 control loop of firefighting fan, so as to get firefighting fan 400 in time indoors
Working condition.
Further, 400 executing agency's strong and weak electricity boxcar of firefighting fan is arranged in distribution box.
It is understood that by strong and weak electricity boxcar setting indoors, can be reduced to a great extent weather in box after
The influence of electric appliance 200；If being arranged strong and weak electricity boxcar in distribution box, weather can be not only reduced to relay 200 in box
Influence, the cable and wire between strong and weak electricity boxcar and distribution box can also be reduced, compared to existing technical solution, be not necessarily to
It increases any cable and wire newly, cost and transformation convenience is greatly saved.
Further, forceful electric power terminal can use quick-connect terminal.
Further, 200 coil both ends of relay can use quick-connect terminal in box.
Further, the normally opened contact of relay 200 can use quick-connect terminal in box.
It is understood that in forceful electric power terminal, box in strong and weak electricity boxcar in 200 coil both ends of relay and box after
The normally opened contact of electric appliance 200 uses quick-connect terminal, facilitates wiring and disassembly.
For example, requiring to carry out relevant device periodic inspection in practical applications, in fire-fighting, therefore works as and check strong and weak electricity
It when breaking down inside boxcar, needs to replace corresponding component, such as relay 200 in box is replaced, institute
Undoubtedly facilitate the maintenance of staff with the setting of quick-connect terminal.
The above, above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng
The utility model is described in detail according to previous embodiment, those skilled in the art should understand that：It is still
It is possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
