A water supply device (1, 18) and a first water outlet pipe 99 which are connected with each other, wherein the first water outlet pipe 99 is used for water outlet. The first water outlet pipe 99 is also connected with the foaming device (2, 5, 19), and the first water outlet pipe 99 is also used for discharging the foam. And the control valve group (8, 9, 11, 12, 13, 14) is used for controlling the bubble discharge of the bubble discharge pipe 131 and/or controlling the water discharge or the foam discharge of the first water outlet pipe 99. And the first controller 20 is used for receiving the operation instruction and controlling the action of the control valve group (8, 9, 11, 12, 13, 14) according to the operation instruction. And the detection device (210, 211, 212, 213, 214, 215) is connected with the first controller 20, wherein the detection device (210, 211, 212, 213, 214, 215) is used for detecting the execution result of the operation instruction, the first controller 20 is also used for judging whether the misoperation exists according to the execution result, and the control valve group (8, 9, 11, 12, 13, 14) is controlled to terminate the misoperation.
In this embodiment, the execution result of the operation instruction is detected by using the detection means (210, 211, 212, 213, 214, 215), and it is determined by the first controller 20 whether there is an erroneous operation or not based on the execution result. The misoperation is stopped by controlling the control valve group (8, 9, 11, 12, 13, 14), so that the misoperation can be timely found, and the misoperation is stopped before the misoperation causes great loss or does not cause loss or a safety accident. By stopping the misoperation, the failure of the equipment can be reduced, the pollution of foam to the water supply devices (1, 18) can be reduced, and the working stability and reliability of the equipment can be improved.
Specifically, by arranging the foam device (2, 5, 19) and the water supply device (1, 18), the fire is extinguished by adopting foam or water according to different conditions of a fire, so that the fire extinguishing speed and the safety and effectiveness of fire extinguishment are improved.

As shown in fig. 1 and 2, in the above-described embodiment, the water supply device (1, 18) includes: a water pump 1 and a water tank 18. The inlet of the water pump 1 communicates with the water tank 18 and the outlet of the water pump 1 communicates with the water tank 18 via a first line 31. The outlet of the water pump 1 is connected to the foam device (2, 5, 19) via a second line 32. The outlet of the water pump 1 is connected to the first outlet pipe 99 via a third pipe 33. The outlet of the foaming device (2, 5, 19) is connected to the foam outlet pipe 131 via a fourth line 34. The outlet of the foaming device (2, 5, 19) is connected to a first outlet pipe 99 via a fifth pipe 35. The control valve group (8, 9, 11, 12, 13, 14) comprises: and the water injection valve 8 is arranged on the first pipeline 31 to control the on-off of the first pipeline 31. And the first water outlet valve 9 is arranged on the third pipeline 33 to control the on-off of the third pipeline 33. And the first bubble outlet valve 13 is arranged on the fourth pipeline 34 to control the on-off of the fourth pipeline 34. And the second bubble outlet valve 14 is arranged on the fifth pipeline 35 to control the on-off of the fifth pipeline 35. The detection means (210, 211, 212, 213, 214, 215) comprise: a water level sensor 211 and a foam level sensor 212. And a water level sensor 211 electrically connected to the first controller 20, the water level sensor 211 acquiring a water level in the water tank 18 and generating water level information. And the foam liquid level sensor 212 is electrically connected with the first controller 20, and the foam liquid level sensor 212 is used for acquiring the foam liquid level in the foam device (2, 5, 19) and generating foam liquid level information. The first controller 20 is specifically configured to receive an operation instruction of discharging foam from the foam discharging pipe 131, and open the first foam discharging valve 13 according to the operation instruction. The first controller 20 is further configured to determine whether one or more of the water filling valve 8, the first water outlet valve 9, and the second bubble outlet valve 14 is/are opened by an erroneous operation according to the received water level information and the received foam level information, and terminate the erroneous operation.
In this embodiment, when the first foam outlet valve 13 is opened, foam can be discharged from the foam outlet pipe 131, the foam liquid level changes, meanwhile, the outlet of the water pump 1 is connected with the foam device (2, 5, 19) through the second pipeline 32, and no control valve is arranged on the second pipeline 32, so that in general, after the first foam outlet valve 13 is opened, and under the condition that other control valves are not opened, water in the water supply device (1, 18) can enter the foam device (2, 5, 19) through the second pipeline 32 through the outlet of the water pump 1 and be discharged along with the foam device (2, 5, 19). If a malfunction occurs, for example, as shown in fig. 1, if all three of the water filling valve 8, the first water outlet valve 9, and the second bubble outlet valve 14 are opened by a malfunction, the bubbles in the foaming device (2, 5, 19) may flow into the water tank 18 through the second bubble outlet valve 14, the first water outlet valve 9, and the water filling valve 8, so that the water in the water tank 18 is polluted, and the amount of the bubbles discharged from the bubble outlet pipe 131 is also reduced, at this time, the water level in the water tank 18 may not decrease or increase, and the foam level in the foaming device (2, 5, 19) may decrease more than when only the first bubble outlet valve 13 is opened, so that it can be determined from the water level information and the foam level information that a malfunction occurs. Similarly, if only the second foam outlet valve 14 is opened by a malfunction, a part of foam may be discharged from the first water outlet pipe 99 through the second foam outlet valve 14, so that the foam liquid level is greatly reduced, and the foam liquid level information is greatly changed, thereby determining that a malfunction occurs. If at least one of the first water outlet valve 9 and the water injection valve 8 is opened by misoperation, the water at the outlet of the water pump 1 can flow to the second pipeline 32 and also can flow to the first pipeline 31 and the third pipeline 33, so that the pressure at the outlet of the water pump 1 is reduced, the flow of the second pipeline 32 is reduced, even the water does not flow through the second pipeline 32 completely, the water entering the foaming device (2, 5, 19) is reduced, the effect of foaming is reduced, whether misoperation exists or not is judged through the foam liquid level change and the water level information change, and the misoperation is corrected in time, so that the phenomenon that the water in the water tank 18 is polluted by the foam is reduced.
It is understood that the filling valve 8, the second bubble outlet valve 14 and the first water outlet valve 9 are all connected to the first controller 20. Therefore, the first controller 20 can directly close the water filling valve 8, the second bubble outlet valve 14 and the first water outlet valve 9, the working efficiency is improved, and the water filling valve 8, the second bubble outlet valve 14 and the first water outlet valve 9 can be closed within the first time when being opened by misoperation.
In addition, it should be noted that the fifth pipeline 35 and the second bubble discharging valve 14 are arranged to discharge both water and bubbles from the first water discharging pipe 99. That is, when the second bubble outlet valve 14 is closed, the first water outlet valve 9 is opened, and the first water outlet pipe 99 only discharges water. When the second bubble outlet valve 14 is opened and the first water outlet pipe 99 is closed, the first water outlet pipe 99 can discharge bubbles.
In some embodiments, first outlet pipe 99 may be used in conjunction with water cannon 4 to eject foam or water, increasing the distance of discharge, facilitating remote fire suppression.
In the above embodiment, as shown in fig. 3 and 4, the foaming device (2, 5, 19) includes: a foam tank 19, a foam pump 2 and a foam mixer 5. The foam tank 19 is used to store foam. The inlet of the foam pump 2 is connected to the foam tank 19 via a sixth line 36. The first inlet of the foam mixer 5 is connected to the outlet of the foam pump 2 via a seventh pipe 37 and the second inlet of the foam mixer 5 is connected to the outlet of the water pump 1 via a second pipe 32. The outlet of the water pump 1 is also connected to the inlet of the foam pump 2 via an eighth line 38, the eighth line 38 being used for supplying water to flush the foam pump 2 and the foam mixer 5. The control valve group (8, 9, 11, 12, 13, 14) further comprises: a supply valve 11 and a flush valve 12. And a liquid supply valve 11 provided on the sixth pipeline 36 to control on/off of the sixth pipeline 36. And a flushing valve 12 arranged on the eighth pipeline 38 to control the on-off of the eighth pipeline 38. The first controller 20 is further configured to determine whether the flushing valve 12 is opened by a malfunction and terminate the malfunction according to the received water level information and the foam liquid level information after the first bubble outlet valve 13 is opened. The first controller 20 is further connected with the water pump 1, and the first controller 20 is further configured to control the water pump 1 to reduce the rotation speed according to the flushing instruction.
In this embodiment, by providing the flushing valve 12 and the eighth pipeline 38, after the foaming operation of the device is finished, the flushing valve 12 is opened to allow water to flow through the eighth pipeline 38, so as to flush the foam pump 2 and the foam mixer, and reduce foam residue in the foam pump 2 and the foam mixer 5, thereby reducing corrosion to these devices and prolonging the service life of the devices. Further, after the first bubble outlet valve 13 is opened, if the flush valve 12 is opened due to an erroneous operation, the water of the water pump 1 flows not only from the second pipeline 32 to the foam mixer 5, but also flows to the foam pump 2 through the eighth pipeline 38, on one hand, the amount of water flowing through the second pipeline 32 is reduced or even eliminated due to the diversion, and the pumping kinetic energy of the foam pump 2 aggravates the water flowing to the eighth pipeline 38, thereby greatly reducing the amount of water flowing through the second pipeline 32. On the other hand, the outlet of the water pump 1 is connected with the inlet of the foam pump 2 through the eighth pipeline 38, the foam tank 19 is connected with the inlet of the foam pump 2 through the sixth pipeline 36, and because the water pressure is high, the water can flow backwards to the sixth pipeline 36 through the eighth pipeline 38, the outlet of the foam tank 19 is blocked and the foam can not be pumped by the foam pump 2, so that the foam is discharged, the foam liquid level is correspondingly led to be possibly unchanged, the water level is greatly reduced, and therefore whether the flushing valve 12 is opened by misoperation can be judged according to the foam liquid level information and the water level information, and the misoperation is timely stopped, namely the flushing valve 12 is closed.
It is to be understood that the set of control valves (8, 9, 11, 12, 13, 14) includes a flush valve 12, and the first controller 20 may close the flush valve 12 by controlling the set of control valves (8, 9, 11, 12, 13, 14).
It will be appreciated that the water pressure required to flush the foam is relatively low compared to flushing the fire, and therefore the speed of the water pump 1 needs to be reduced during the foam flushing operation before the flush valve 12 can be opened to facilitate the flow of water from the water pump 1 through the eighth line 38 to the foam pump 2 and the foam mixer 5 to flush the foam.
It is also noted that by providing foam tank 19, foam storage is facilitated, so that fire engine 50 uses foam to extinguish fires in locations where there is no source of foam. By providing the liquid supply valve 11, it is convenient to disconnect the sixth pipeline 36, and the foam flow to the pipeline subsystem is prevented from eroding the pipeline. By providing a foam pump 2, it is facilitated to draw foam from the foam tank 19. By providing foam mixer 5, it is convenient to provide a special container to mix the foam and water to form a mixed liquid, reducing erosion to other pipes. The setting of second pipeline 32 is convenient for water inflow foam mixer 5 and foam and is mixed, through setting up the flushing pipe way, and washes the access connection of pipeline and foam pump 2, is convenient for wash foam pump 2 and foam mixer 5, reduces the foam residue in foam pump 2 and the foam mixer 5, extension equipment life. Through the setting of revolution speed sensor 215, except being used for detecting the 1 rotational speed of water pump in order to avoid the flush valve 12 of open by mistake, can also control the 1 rotational speed of water pump more accurately to accurately control water pressure, thereby can guarantee the height of fetching water when fetching water to the eminence, when fetching water to the low department, can reduce the 1 rotational speed of water pump and reduce the energy consumption.
In the above embodiment, the anti-misoperation system 54 further includes: and the air compressor 3 is connected with the foaming device (2, 5, 19), and the air compressor 3 is used for supplying compressed air to the foaming device (2, 5, 19).
