Description

Technical Field

[0001] The present invention belongs to the technical field of fire fighting equipment, and in particular relates to a fire fighting system assembly and fire fighting equipment. Background Art

[0002] The foam supply methods of the fire fighting system on the existing fire trucks are mainly negative pressure suction type and positive pressure injection type. The negative pressure suction type mainly relies on the high-speed flow of water flowing through the venturi tube to generate negative pressure in the venturi tube, thereby sucking the foam and mixing it with water. The positive pressure injection type mainly relies on the foam pump to press the foam to the inlet or outlet of the water pump.

[0003] For the positive pressure fire fighting system, if the foam is pressed toward the inlet of the water pump, the foam cannot be output when the water pump stops working, causing the entire fire fighting system to be paralyzed; if the foam is pressed toward the outlet of the water pump, the outlet pressure of the water pump is high, and a larger pressure is required to press the foam in, resulting in higher performance requirements for the foam pump. Summary of the invention

[0004] In view of the above-mentioned defects or shortcomings, the present invention provides a fire fighting system assembly and fire fighting equipment, aiming to solve the technical problem that the working condition of the water pump in the existing positive pressure push-in fire fighting system has a significant impact on the foam supply.

DETAILED DESCRIPTION

[0030] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] The fire fighting system assembly of the present invention will be described below with reference to the accompanying drawings.

[0032] The present invention provides a fire fighting system assembly, such as Figure 1 and Figure 2 As shown, the fire fighting system assembly includes a water supply system S1 and a foam supply system S2.

[0033] The water supply system S1 includes a water supply unit 11, a water pump unit 12 and a spray unit 13 connected in sequence. The water supply unit 11 is used to provide a water source, and the water pump unit 12 is used to pump water from the water supply unit 11 to the spray unit 13. The spray unit 13 is provided with a fire gun 131 or a fire cannon 132 for water spraying.

[0034] The foam supply system S2 includes a foam supply unit 21, a pump foam unit 22 and an output control unit 23 which are connected in sequence. The foam supply unit 21 is used to provide foam, and the pump foam unit 22 is used to pump the foam of the foam supply unit 21 to the output control unit 23. The inlet of the output control unit 23 is connected to the pipeline of the pump foam unit 22. The output control unit 23 is also provided with a first output port P1 and a second output port P2. The output control unit 23 can selectively supply the liquid pumped out of the pump foam unit 22 to the first output port P1 or the second output port P2 by switching the state.

[0035] The first output port P1 is communicated with the inlet pipeline of the water pump unit 12 , and the second output port P2 is communicated with the outlet pipeline of the water pump unit 12 .

[0036] When the water pump unit 12 is in operation, the output control unit 23 is controlled to switch state so that the inlet of the output control unit 23 is connected to the first output port P1. After the inlet of the output control unit 23 is connected to the first output port P1, the foam pumped out by the pump foam unit 22 will sequentially pass through the inlet of the output control unit 23, the first output port P1 and flow to the inlet pipeline of the water pump unit 12. Since the water pump unit 12 is in operation, the water pump unit 12 will actively suck the liquid at the inlet when it is running, so that the pump foam unit 22 only needs to provide a small pumping pressure to mix the foam with water.

[0037] When the water pump unit 12 is in the shutdown state, the output control unit 23 is controlled to switch the state so that the inlet of the output control unit 23 is connected with the second output port P2. After the inlet of the output control unit 23 is connected with the second output port P2, the foam pumped out by the pump foam unit 22 will flow to the outlet pipeline of the water pump unit 12 through the inlet of the output control unit 23 and the second output port P2 in sequence, thereby realizing the smooth output of the foam.

[0038] In summary, the fire protection system assembly of the present invention controls the switching state of the output control unit 23 according to the operation status of the water pump unit 12. When the water pump unit 12 is in operation, the inlet of the output control unit 23 is controlled to be connected with the first output port P1. When the water pump unit 12 is in shutdown, the inlet of the output control unit 23 is controlled to be connected with the second output port P2. This frees the foam supply system S2 from dependence on the operation of the water pump unit 12 and increases the scope of application and usage scenarios.

[0039] In the embodiment of the present invention, the state switching of the output control unit 23 can be achieved through signal electronic control. For example, the output control unit 23 can be an electromagnetic reversing valve, a hydraulically controlled reversing valve, etc.

[0040] In an embodiment of the present invention, the fire protection system assembly may further include a controller, which is used to control the inlet of the output control unit 23 to be connected to the first output port P1 when the pump unit 12 is in operation, and to control the inlet of the output control unit 23 to be connected to the second output port P2 when the pump unit 12 is in a shutdown state.

[0041] like Figure 3 and Figure 4As shown, in an embodiment of the present invention, the foam supply unit 21 may include a foam storage tank 211a and a first foam pipeline 211, one end of the first foam pipeline 211 is connected to the foam storage tank 211a, and the other end is connected to the inlet pipeline of the pump foam unit 22. The foam storage tank 211a may be built into a fire truck or fire equipment, and foam liquid is stored in the foam storage tank 211a. Through the foam storage tank 211a and the first foam pipeline 211, the foam storage tank 211a can supply foam to the pump foam unit 22.

[0042] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the first foam pipeline 211 is provided with a tank supply control valve 211b for controlling the on-off and a one-way check valve 31. The one-way check valve 31 can prevent the foam or flushing water from flowing back and causing the foam liquid in the foam storage tank 211a to be contaminated. When the foam storage tank 211a supplies foam to the pump foam unit 22, the tank supply control valve 211b needs to be kept open.

[0043] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the foam supply unit 21 may further include a second foam pipeline 212, one end of the second foam pipeline 212 is connected to the outside, and the other end is connected to the inlet pipeline of the pump foam unit 22, and an external suction control valve 212a for controlling the on-off is provided on the second foam pipeline 212. By providing the second foam pipeline 212, it is possible to realize that the external foam source supplies foam to the pump foam unit 22 in the fire truck.

[0044] Specifically, the fire fighting system assembly of the present invention has two working modes: tank supply-output foam and external suction-output foam. Figure 3 and Figure 4 As shown, when the fire fighting system assembly is in the tank supply-output foam working mode, the tank supply control valve 211b is opened, the external suction control valve 212a is closed, and the foam liquid in the foam storage tank 211a passes through the first foam pipeline 211, the pump foam unit 22 and the output control unit 23 in sequence, and is finally sprayed out from the spray unit 13. Figure 1 and Figure 2 As shown, when the fire fighting system assembly is in the external suction-output foam working mode, the tank supply control valve 211b is closed, the external suction control valve 212a is opened, and the foam liquid of the external foam source passes through the second foam pipeline 212, the pump foam unit 22 and the output control unit 23 in sequence, and finally is ejected from the ejection unit 13. By setting the first foam pipeline 211 and the second foam pipeline 212, practical scenarios can be enriched and multi-channel supply of foam can be guaranteed.

[0045] like Figure 1As shown, in the embodiment of the present invention, a circulation pipe 28 is provided between the pump foam unit 22 and the foam supply unit 21. The circulation pipe 28 can be used as a transfer station for foam storage. Under different working conditions, excess foam can be temporarily stored in the circulation pipe 28. The circulation pipe 28 is provided with a plurality of connection ports to facilitate communication with various pipelines.

[0046] like Figure 5 As shown, in an embodiment of the present invention, the foam supply system S2 may further include a pumping foam pipeline 24, on which a pumping control valve 241 for controlling on and off is provided, one end of the pumping foam pipeline is connected to the foam storage tank 211a, and the other end is connected to the outlet pipeline of the pump foam unit 22. When the output control unit 23 outputs foam, the pumping control valve 241 is in a cut-off state. When the foam liquid in the foam storage tank 211a is insufficient, the second foam pipeline 212 may be connected to an external foam source, and the pumping control valve 241 may be controlled to be turned on, and the output control unit 23 may be controlled to be cut off. External foam flows into the foam storage tank 211a through the second foam pipeline 212, the pump foam unit 22, and the pumping foam pipeline 24, thereby filling the foam storage tank 211a with foam.

[0047] like Figure 1 As shown, in the embodiment of the present invention, the foam supply system S2 further includes a flow regulating pipeline 25, on which a flow regulating valve 251 is provided. One end of the flow regulating pipeline 25 is connected to the outlet pipeline of the pump foam unit 22, and the other end is connected to the inlet pipeline of the pump foam unit 22. The other end of the flow regulating pipeline 25 is preferably connected to the circulation pipe 28. When the foam supply system S2 is in operation, the pump foam unit 22 can be controlled to output at a flow rate higher than the actual required flow rate, and then the flow regulating valve 251 can be controlled to be turned on. At this time, part of the foam output by the pump foam unit 22 will flow to the output control unit 23 or the second foam pipeline 212, and the other part will flow back to the circulation pipe 28 through the flow regulating pipeline 25. By gradually adjusting the opening of the flow regulating valve 251, the reflux amount of the flow regulating pipeline 25 can be controlled, thereby realizing the precise adjustment of the output flow of the pump foam unit 22. This adjustment method can be adapted to a variety of working modes, and the flow regulation accuracy is higher.

[0048] In the embodiment of the present invention, the foam supply system S2 further includes a safety pressure relief pipeline, one end of which is connected to the outlet of the pump foam unit 22, and a pressure relief valve 32 is provided on the safety pressure relief pipeline, which is used to open when the outlet liquid pressure of the pump foam unit 22 reaches a preset value. By providing the safety pressure relief pipeline, the safe working pressure of the foam supply system S2 can be guaranteed.

[0049] like Figure 6 and Figure 7As shown, in the embodiment of the present invention, the foam supply system S2 further includes a foam external supply pipeline 26, on which is provided an external supply control valve 261 for controlling the on-off, one end of the foam external supply pipeline 26 is connected to the outlet pipeline of the pump foam unit 22, and the other end is connected to the outside. Through the cooperation of the foam external supply pipeline 26, the first foam pipeline 211, and the second foam pipeline 212, multiple fire-fighting equipment can be connected in series.

[0050] Specifically, taking a fire truck equipped with the fire fighting system assembly of the present invention as an example, after the foam liquid in the foam storage tank 211a of the A fire truck is output from the foam external supply pipeline 26, it can enter the second foam pipeline 212 of the B fire truck. The B fire truck can choose to supply the foam of the second foam pipeline 212 to the output control unit 23, the pumping foam pipeline 24 or the foam external supply pipeline 26 of the B fire truck. According to the different foam output positions, more fire trucks can be connected in series in sequence after the B fire truck. That is, the fire fighting system assembly of the present invention can greatly enrich the use scenarios of fire fighting equipment, and can very conveniently realize the series connection between multiple fire fighting system assemblies.

[0051] like Figure 8 As shown, in an embodiment of the present invention, the fire protection system assembly further includes a foam flushing pipeline 27, one end of which is connected to the water supply unit, and the other end is connected to the inlet pipeline of the pump foam unit 22. A foam flushing valve 271 for controlling the on-off is also provided on the foam flushing pipeline 27. When the foam supply system is working, the foam flushing valve 271 is in a cut-off state to prevent foam from entering the foam flushing pipeline 27. When the foam supply system is finished working, there will be foam liquid remaining in the pipeline of the foam supply system. By controlling the foam flushing valve 271 to open and controlling the pump foam unit 22 to operate, the foam liquid remaining in the pipeline of the foam supply system can be flushed in time to prevent the foam liquid from corroding the pipeline.

[0052] like Figure 8 As shown, in the embodiment of the present invention, the foam supply system S2 further includes a discharge pipeline 29, one end of which is connected to the outlet pipeline of the pump foam unit 22, and the other end is connected to the outside. The discharge pipeline is also provided with a discharge control valve 291 for controlling the on-off. By providing the discharge pipeline, the water used to flush the pipeline of the foam supply system can be discharged.

[0053] In summary, the foam supply system S2 of the present invention has at least six working modes, namely external suction-output foam, tank supply-output foam, external suction-pumping foam, external suction-external supply foam, tank supply-external supply foam, and flushing.

[0054] like Figure 1 and Figure 2As shown, when the foam supply system S2 is in the working mode of external suction and output of foam, and the pump unit 12 is in operation, the external foam is output through the second foam pipeline 212, the pump foam unit 22, and the first output port P1 of the output control unit 23 in sequence; when the foam supply system S2 is in the working mode of external suction and output of foam, and the pump unit 12 is in shutdown state, the external foam is output through the second foam pipeline 212, the pump foam unit 22, and the second output port P2 of the output control unit 23 in sequence.

[0055] like Figure 3 and Figure 4 As shown, when the foam supply system S2 is in the tank supply-output foam working mode, the foam in the foam storage tank 211a is output in sequence through the first foam pipeline 211, the pump foam unit 22, and the output control unit 23. After the pump foam unit 22 has been running for a period of time, if it is detected that the liquid level of the foam storage tank 211a is lower than the preset value, the pump foam unit 22 needs to be controlled to be closed, and the personnel need to be reminded to add foam liquid into the foam storage tank 211a to avoid the pump foam unit 22 from idling for a long time.

[0056] like Figure 5 As shown, when the foam supply system S2 is in the external suction-pumping foam working mode, the external foam enters the foam storage tank 211a through the second foam pipeline 212, the pump foam unit 22, and the pumping foam pipeline 24 in sequence, so as to fill the foam storage tank 211a with foam liquid. When the liquid level of the foam storage tank 211a is higher than a certain set value, it means that the foam storage tank 211a is completely filled with foam, and at this time, the pump foam unit 22 can be controlled to stop operating.

[0057] like Figure 6 As shown, when the foam supply system S2 is in the external suction-external foam supply working mode, the external foam is output in sequence through the second foam pipeline 212, the pump foam unit 22, and the foam external supply pipeline 26. In this mode, multiple sets of foam supply systems S2 can be connected in series.

[0058] like Figure 7 As shown, when the foam supply system S2 is in the tank supply-external foam supply working mode, the foam in the foam storage tank 211a is output in sequence through the first foam pipeline 211, the pump foam unit 22, and the foam external supply pipeline 26. In this mode, multiple foam supply systems S2 can be connected in series, or the foam supply system S2 and external fire-fighting equipment can be connected in series.

[0059] like Figure 8As shown, when the foam supply system S2 is in the flushing working mode, the pump foam unit 22 sucks water from the water tank 111 or the outside through the foam flushing pipeline 27, and then flushes the pipeline of the foam supply system S2, and the flushed liquid can be discharged through the liquid discharge pipeline. In this mode, the pump foam unit 22 can operate at a default speed. In the water tank 111 water supply mode, if the water tank 111 is insufficient, it is necessary to control the foam pump to stop, so as to avoid the pump foam unit 22 from idling for a long time.

[0060] like Figure 1 As shown, in the embodiment of the present invention, due to the existence of the flow regulating pipeline 25, when the pump foam unit 22 outputs foam, it can compare the actual foam flow demand with the current output flow demand of the pump foam unit 22 to adjust the opening of the flow regulating valve 251 accordingly, thereby realizing accurate control of the output flow of the pump foam unit 22. The current output flow of the pump foam unit 22 can be detected by a flow meter set at the outlet of the pump foam unit 22.

[0061] In an embodiment of the present invention, after the pump foam unit 22 has been running for a period of time, if it is detected that the pump foam unit 22 has no flow output for a continuous period of time, the pump foam unit 22 can be controlled to shut down to avoid the pump foam unit 22 from idling for a long time.

[0062] In the embodiment of the present invention, when the output unit selects the first output port P1 for output, if the water pump unit 12 is shut down, the pump foam unit 22 needs to be controlled to shut down as well to prevent the foam from contaminating the water source.

[0063] like Figure 1 As shown, in an embodiment of the present invention, the water supply unit 11 includes a water tank 111, which is used to store clean water. A first water supply pipeline 112 is provided between the water tank 111 and the inlet of the water pump unit 12. The first water supply pipeline 112 is provided with a tank water supply valve 112a for controlling the on-off. By controlling the conduction of the tank water supply valve 112a, the water tank 111 can supply water to the water pump unit 12.

[0064] like Figure 1 As shown, in the embodiment of the present invention, the water supply unit 11 further includes a second water supply pipeline 113, one end of which is connected to the outside, and the other end is connected to the inlet pipeline of the water pump unit 12. The second water supply pipeline 113 is used to supply water from the outside to the inlet of the water pump unit 12, and the second water supply pipeline 113 may also be provided with an external water supply valve 113a for controlling the on-off.

[0065] Through the first water supply pipeline 112 and the second water supply pipeline 113 , water can be taken from the outside of the pump unit 12 and from the water tank 111 .

[0066] like Figure 8 As shown, in the embodiment of the present invention, one end of the foam flushing pipeline 27 can be connected to the water tank 111 through a pipeline, and an external water injection port can be provided on the foam flushing pipeline 27. That is, the water source of the foam flushing pipeline 27 can come from the water tank 111 or the outside.

[0067] like Figure 1 As shown, in an embodiment of the present invention, the pump unit 12 may be provided with two output water paths, one of which is connected to the spray unit 13, and the other is connected to the water tank 111. The water tank 111 may be filled with water through the output water path connected between the water tank 111 and the pump unit 12.

[0068] like Figure 1 As shown, in an embodiment of the present invention, the water supply system S1 includes a direct water supply unit 14, and the direct water supply unit 14 includes a direct water supply pipeline 141, one end of the direct water supply pipeline 141 is used to connect to external pressure water, and the other end is connected to the outlet pipeline of the pump unit 12. When the pump unit 12 is in a shutdown state, the foam pumped out by the pump foam unit 22 flows directly to the outlet of the pump unit 12, and is mixed with the water in the direct water supply pipeline 141 and sprayed out from the spray unit 13. By setting up the direct water supply unit 14, the dependence on the pump unit 12 can be completely eliminated, so that the emergency use of the system assembly can be realized when the pump unit 12 fails.

[0069] like Figure 1 As shown, in the embodiment of the present invention, the spray unit 13 includes a fire gun 131 and a fire monitor 132 .

[0070] In the embodiment of the present invention, the pump foam unit 22 is a gear pump, and the water pump unit 12 is a water pump.

[0071] In an embodiment of the present invention, the valves on each pipeline may be electrically controlled valves or hydraulically controlled valves, and the system may be provided with a controller, which may automatically control the corresponding valve switching state with one button according to the manually selected working mode, thereby realizing one-button operation.

[0072] In summary, when the fire-fighting system assembly of the present invention outputs foam, by switching the state of the output control unit 23 according to the operating state of the water-pumping unit 12, it not only gets rid of the dependence on the operation of the water-pumping unit 12, but also can realize the independent output of foam and the output in conjunction with the water-pumping unit 12. At the same time, when used in conjunction with the water-pumping unit 12, the working pressure required by the pump foam unit 22 is also relatively small. The fire-fighting system assembly of the present invention has a variety of working modes. In each working mode, it can realize precise control of the foam flow output, and in the working mode of external foam supply, it can very conveniently provide foam to other fire-fighting vehicles or fire-fighting equipment, realizing linkage with other fire-fighting vehicles or fire-fighting equipment. The various valves in the fire-fighting system assembly of the present invention can be controlled by signals, and the one-button mode automatic switching of the system assembly can be realized, which greatly simplifies the operation process.
