Description
Technical field
The utility model belongs to tunnel fire hazard technical field of fire control, and in particular to it is a kind of applied to tunnel based on PLC's
Intelligent fire fire-fighting system.
Background technology
With developing rapidly for social economy, national basis construction is advanced by leaps and bounds, and highway, railway construction flourish, and lead to
Car kilometer rapid growth, roads and tunnels development is fast, and tunnel is more, and the traffic accident that brings therewith, tunnel fire hazard are more and more frequent, closely
Several years are in rapid increase situation, and the annual tunnel fire hazard accident of China just beats over one hundred, cause mass casualties and property is damaged
Lose, therefore tunnel fire hazard fire-fighting prevention and control are significant.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of intelligent fire fire-fighting based on PLC
System.
The utility model is achieved through the following technical solutions：
A kind of intelligent fire fire-fighting system based on PLC, along tunnel smoke duct, Smoke are provided with the top in tunnel
At least one port of export in road is provided with blower fan, smoke duct is provided with multiple electronic Adjustable air ports along tunnel at equal intervals,
A Smoke Sensor and a shower nozzle are respectively arranged in each electronic Adjustable air port neighbouring position,
A total supply channel is provided with smoke duct, total supply channel is connected by branch pipeline with shower nozzle, and
The electric control valve for controlling shower nozzle to cut-off is set in each branch pipeline；
The Smoke Sensor connects PLC, and it is electronic adjustable that PLC connects each by air port drive module
The motor in air port, PLC connects each electric control valve by valve drive module, and PLC is also connected with blower fan.
In the above-mentioned technical solutions, the cross section of the smoke duct is square.
In the above-mentioned technical solutions, the Smoke Sensor distance electronic Adjustable air port 0.5-1m nearest with it, shower nozzle distance
Nearest electronic Adjustable air port 0.5-1m with it.
Advantage of the present utility model and have the beneficial effect that：
The utility model sets smoke duct in tunnel, and smoke duct carry out multi-point arrangement Smoke Sensor,
Electronic Adjustable air port and shower nozzle, carry out the fixed point condition of a fire by Smoke Sensor and detect, with reference to PLC, by electronic adjustable
Air port, which is realized, carries out fixed point smoke evacuation, and pointing fire-extinguishing is carried out by shower nozzle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is smoke duct cross-sectional structure schematic diagram of the present utility model.
Fig. 3 is electric control structure block diagram of the present utility model.
Embodiment
The technical solution of the utility model is further illustrated with reference to specific embodiment.
A kind of intelligent fire fire-fighting system based on PLC involved by the utility model, referring to accompanying drawing 1, the top in tunnel
End is provided with smoke duct 4 along tunnel, and the two ends outlet of smoke duct 4 is connected with ambient atmosphere, smoke duct 4 at least one
The port of export is provided with blower fan 5, smoke duct 4 is provided with multiple electronic Adjustable air ports 1 along tunnel at equal intervals, each electronic
The neighbouring position of Adjustable air port 1 is respectively arranged a Smoke Sensor 3 and a shower nozzle 2,
Referring to accompanying drawing 2, the cross section of the smoke duct 4 is square, and a total feed pipe is provided with smoke duct 4
Road 6, total supply channel 6 is connected by branch pipeline 7 with shower nozzle 2, and sets electric control valve 8 in each branch pipeline 7, to control
Make cut-offfing for each shower nozzle 2.
Referring to accompanying drawing 3, the Smoke Sensor 3 connects PLC, and PLC is connected by air port drive module
(electronic Adjustable air port is driven each electronic Adjustable air port 1 by motor, and PLC connects each electricity by air port drive module
The motor of dynamic Adjustable air port 1), PLC connects each electric control valve 8, PLC by valve drive module
It is also connected with blower fan 5.When the condition of a fire occurs for tunnel somewhere, the Smoke Sensor nearest apart from burning things which may cause a fire disaster point detects fire hazard aerosol fog at first
Signal, now PLC judge as fire location near the Smoke Sensor, then PLC control blower fan 5 open, together
When control the electronic Adjustable air port near the Smoke Sensor to open (remaining electronic Adjustable air port be closed mode), pinpointed
Smoke evacuation, while PLC controls the electric control valve 8 of the shower nozzle 2 near the Smoke Sensor to open, is determined by shower nozzle 2
Point fire extinguishing.
Exemplary description is done to the utility model above, it should explanation, do not departed from core of the present utility model
In the case of the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
Protection domain of the present utility model is each fallen within replacing.
