Drawings
The utility model is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a block diagram of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides a fire control water mist pump group switch board based on pressure self-adaptation, including dual power supply auto-change over device 1, PLC controller 2, pressure sensor 3, level sensor 4, alarm device 5, steady voltage pump package 6, fire control pump package 7, water supply valve 8, air switch 9, contactor 10 and thermal relay 11, pressure sensor 3, level sensor 4 all inserts PLC controller 2, PLC controller 2 respectively with alarm device 5, the control switch is organized and is connected, PLC controller 2 still is connected with the control center that disappears, output signal gives the control center that disappears. PLC controller 2 be connected with steady voltage pump package 6, fire pump package 7, water supply valve 8 through control switch group, control switch group including air switch 9, contactor 10 and thermal relay 11, dual power switching device 1 links to each other with control switch group and steady voltage pump package 6, fire pump package 7, water supply valve 8, dual power switching device 1 insert A way inlet wire power, B way inlet wire power respectively.
According to the specific embodiment, the pressure sensor 3 is used for collecting pipeline pressure data and transmitting the pipeline pressure data to the PLC 2, and the pressure stabilizing pump set 6 is intermittently started according to the pressure condition and is used for maintaining the working pressure at ordinary times and ensuring the sealing property of the pipeline. The control cabinet is also provided with a liquid level sensor 4 and a water replenishing valve 8, and when the liquid level reaches a set median value, the water replenishing valve 8 automatically opens water replenishing; when the liquid level reaches a set high value, the water replenishing valve 8 is automatically closed; when the liquid level reaches the set low value, the pressure stabilizing pump unit 6 and the fire pump unit 7 can not be started, and alarm information is output simultaneously.
It is worth noting that when the far-end emergencies fire disaster and opens the spraying valve, the system automatically detects that the pressure can not be normally maintained, when the situation lasts for a period of time (generally 10-15s), the system automatically judges to enter a fire extinguishing mode, at the moment, the pressure stabilizing pump set 6 quits working, the fire fighting pump set 7 emergently starts to enter a fire extinguishing stage; correspondingly, the system can output alarm information to the elimination center. PLC can be according to the pressure data who gathers at this stage of putting out a fire, the start-up quantity of intelligent regulation fire pump to satisfy the demand of putting out a fire under the different situations. As a protection, the system only keeps one fire pump working when the pressure exceeds the maximum set pressure.
The technical advantages of this embodiment are:
(1) the pressure stabilizing pump has a fire monitoring function based on pressure detection, and the normal pressure of the pipeline is maintained through the intermittent work of the pressure stabilizing pump.
(2) Based on pressure detection data, the work of automatically increasing and decreasing the pump is realized through intelligent judgment of the PLC so as to maintain the official website pressure to realize the maximum fire extinguishing effect
(3) The system provides protection for the lowest pressure and the highest pressure. When the pressure exceeds the maximum set pressure, the system flexibly adjusts the number of the fire pumps, only one fire pump is reserved for working, and an alarm device is output.
(4) When the PLC control system acquires all alarm information, on one hand, related personnel can be reminded of maintenance and troubleshooting through the alarm device of the control cabinet; on the other hand, one path of signal is output to the cancellation control center, so that the stability, safety and reliability of the system are greatly improved.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
