Description

Technical Field

[0001] This invention belongs to the field of fire protection equipment technology, specifically relating to a fire protection system assembly and fire protection equipment. Background Technology

[0002] The existing foam supply methods for fire-fighting systems on fire trucks mainly include negative pressure suction and positive pressure injection. Negative pressure suction primarily utilizes a high-speed flow of water passing through a venturi tube, creating negative pressure within the tube to draw in foam and mix it with the water. Positive pressure injection mainly uses a foam pump to force foam towards the pump's inlet or outlet.

[0003] For positive pressure fire suppression systems, if the foam is directed towards the pump inlet, the foam cannot be output when the pump stops working, causing the entire fire suppression system to fail. If the foam is directed towards the pump outlet, the pump outlet pressure is high, requiring a large pressure to inject the foam, which places high demands on the performance of the foam pump. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the present invention provides a fire protection system assembly and fire protection equipment, which aims to solve the technical problem that the operation of the water pump in the existing positive pressure fire protection system has a significant impact on the foam supply.

The water supply system includes a water supply unit, a pumping unit, and a spraying unit connected in sequence. The foam supply system includes a foam supply unit, a foam pumping unit, and an output control unit connected in sequence. The output control unit is provided with a first output port and a second output port. The output control unit is used to selectively supply the liquid pumped out by the foam pumping unit to the first output port or the second output port. The first output port is connected to the inlet pipe of the pumping unit, and the second output port is connected to the outlet pipe of the pumping unit.

[0008] In an embodiment of the present invention, the foam supply system further includes a foam pumping pipeline, which is provided with a pumping control valve for controlling the on / off state.

[0010] In an embodiment of the present invention, the foam supply system further includes an external foam supply pipeline, which is provided with an external supply control valve for controlling the on / off state.

[0013] In an embodiment of the present invention, the foam supply system further includes a safety pressure relief pipeline, one end of which is connected to the outlet of the pump foam unit. A pressure relief valve is provided on the safety pressure relief pipeline, which is used to open when the outlet liquid pressure of the pump foam unit reaches a preset value.

[0014] In an embodiment of the present invention, the water supply system includes a direct water supply unit, which includes a direct water supply pipeline. One end of the direct water supply pipeline is connected to external pressurized water, and the other end is connected to the outlet pipeline of the pumping unit.

[0015] To achieve the above objectives, the present invention also provides a fire-fighting device, wherein the fire-fighting device includes the fire-fighting system assembly described above.

Detailed Implementation

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

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

[0032] This invention provides a fire protection system assembly, such as Figure 1 and Figure 2 As shown, the fire protection 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 pumping unit 12, and a spraying unit 13 connected in sequence. The water supply unit 11 is used to provide a water source, the pumping unit 12 is used to pump the water from the water supply unit 11 to the spraying unit 13, and the spraying unit 13 is equipped with a fire gun 131 or a fire monitor 132 for supplying water spray.

[0034] The foam supply system S2 includes a foam supply unit 21, a foam pumping unit 22, and an output control unit 23 connected in sequence. The foam supply unit 21 is used to supply foam, and the foam pumping unit 22 is used to pump the foam from 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 foam pumping 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 by the foam pumping unit 22 to the first output port P1 or the second output port P2 by state switching.

[0035] The first output port P1 is connected to the inlet pipe of the water pumping unit 12, and the second output port P2 is connected to the outlet pipe of the water pumping unit 12.

[0036] When the water pump unit 12 is in operation, the control output control unit 23 switches states, connecting its inlet 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 by the foam pump unit 22 flows sequentially through the inlet of the output control unit 23, the first output port P1, and into the inlet pipe of the water pump unit 12. Because the water pump unit 12 is in operation, it actively draws in liquid from the inlet, thus requiring only a small pumping pressure to mix the foam with the water.

[0037] When the pumping unit 12 is in a stopped state, the control output control unit 23 switches states, connecting the inlet of the output control unit 23 with the second output port P2. After the inlet of the output control unit 23 is connected to the second output port P2, the foam pumped out by the foam pumping unit 22 will flow sequentially through the inlet of the output control unit 23 and the second output port P2 to the outlet pipeline of the pumping unit 12, thus achieving smooth foam output.

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

[0039] In embodiments of the present invention, the state switching of the output control unit 23 can be achieved by signal electronic control, such as the output control unit 23 being an electromagnetic reversing valve, a hydraulic 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 connect with 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 connect with the second output port P2 when the pump unit 12 is in shutdown.

[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-fighting equipment. The foam storage tank 211a stores foam liquid. Through the foam storage tank 211a and the first foam pipeline 211, foam can be supplied from the foam storage tank 211a to the pump foam unit 22.

[0042] like Figure 3 and Figure 4 As shown, in an embodiment of the present invention, the first foam pipeline 211 is equipped with a tank supply control valve 211b for controlling the on / off state and a one-way check valve 31. The one-way check valve 31 can prevent foam or flushing water from flowing back and contaminating the foam liquid in the foam storage tank 211a. When the foam storage tank 211a supplies foam to the pump foam unit 22, the tank supply control valve 211b needs to remain 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 pipe 212. One end of the second foam pipe 212 is connected to the outside, and the other end is connected to the inlet pipe of the pump foam unit 22. The second foam pipe 212 is provided with an external suction control valve 212a for controlling its on / off state. By setting the second foam pipe 212, foam can be supplied from an external foam source to the pump foam unit 22 inside the fire truck.

[0044] Specifically, the fire protection system assembly of the present invention has two working modes: tank-supply-output foam and external suction-output foam. For example... Figure 3 and Figure 4 As shown, when the fire protection system assembly is in the tank-supply-output foam working mode, the tank supply control valve 211b is open, the external suction control valve 212a is closed, and the foam liquid in the foam storage tank 211a passes sequentially through the first foam pipeline 211, the pump foam unit 22, and the output control unit 23, and is finally sprayed out from the spraying unit 13. Figure 1 and Figure 2 As shown, when the fire protection system assembly is in the external suction-output foam working mode, the tank supply control valve 211b is closed and the external suction control valve 212a is open. The foam liquid from the external foam source passes sequentially through the second foam pipeline 212, the pump foam unit 22, and the output control unit 23, and is finally sprayed out from the spraying unit 13. By setting the first foam pipeline 211 and the second foam pipeline 212, practical scenarios can be enriched and the 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 foam pump unit 22 and the foam supply unit 21. By providing the circulation pipe 28, it can serve as a transfer station for foam storage. Under different operating conditions, excess foam can be temporarily stored in the circulation pipe 28. The circulation pipe 28 is provided with multiple 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 foam pumping pipeline 24, which is equipped with a pumping control valve 241 for controlling its on / off state. One end of the foam pumping pipeline is connected to the foam storage tank 211a, and the other end is connected to the outlet pipeline of the foam pumping unit 22. When the output control unit 23 outputs foam, the pumping control valve 241 is in the off state. When the foam liquid in the foam storage tank 211a is insufficient, the second foam pipeline 212 can be connected to an external foam source, and the pumping control valve 241 can be opened, while the output control unit 23 is closed. External foam flows into the foam storage tank 211a through the second foam pipeline 212, the foam pumping unit 22, and the foam pumping pipeline 24, thereby filling the foam storage tank 211a with foam.

[0047] like Figure 1 As shown, in an embodiment of the present invention, the foam supply system S2 further includes a flow regulating pipe 25, on which a flow regulating valve 251 is provided. One end of the flow regulating pipe 25 is connected to the outlet pipe of the pump foam unit 22, and the other end is connected to the inlet pipe of the pump foam unit 22. The other end of the flow regulating pipe 25 is preferably connected to the circulation pipe 28. When the foam supply system S2 is running, the pump foam unit 22 can be controlled to output a flow rate higher than actually required, and then the flow regulating valve 251 can be controlled to open. 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 pipe 212, and the other part will flow back to the circulation pipe 28 through the flow regulating pipe 25. By gradually adjusting the opening of the flow regulating valve 251, the return flow of the flow regulating pipe 25 can be controlled, thereby achieving precise adjustment of the output flow of the pump foam unit 22. This adjustment method can adapt to various working modes and has higher flow regulation accuracy.

[0048] In an embodiment of the present invention, the foam supply system S2 further includes a safety pressure relief pipeline. One end of the safety pressure relief pipeline 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. The pressure relief valve 32 is used to open when the outlet liquid pressure of the pump foam unit 22 reaches a preset value. By setting up the safety pressure relief pipeline, the safe operating pressure of the foam supply system S2 can be guaranteed.

[0049] like Figure 6 and Figure 7As shown, in an embodiment of the present invention, the foam supply system S2 further includes an external foam supply pipeline 26. The external foam supply pipeline 26 is equipped with an external supply control valve 261 for controlling its on / off state. One end of the external foam 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 external foam supply pipeline 26, the first foam pipeline 211, and the second foam pipeline 212, multiple fire-fighting devices can be connected in series.

[0050] Specifically, taking a fire truck equipped with the fire protection system assembly of the present invention as an example, the foam liquid in the foam storage tank 211a of fire truck A, after being output from the external foam supply pipeline 26, can enter the second foam pipeline 212 of fire truck B. Fire truck B can choose to supply foam from the second foam pipeline 212 to the output control unit 23, the foam pumping pipeline 24, or the external foam supply pipeline 26 of fire truck B. Depending on the foam output location, more fire trucks can be connected in series after fire truck B. That is, the fire protection system assembly of the present invention can greatly enrich the application scenarios of fire protection equipment and can very easily realize the series connection between multiple fire protection system assemblies.

[0051] like Figure 8 As shown in the embodiment of the present invention, the fire protection system assembly further includes a foam flushing pipe 27. One end of the foam flushing pipe 27 is connected to the water supply unit, and the other end is connected to the inlet pipe of the pump foam unit 22. The foam flushing pipe 27 is also equipped with a foam flushing valve 271 for controlling its on / off state. When the foam supply system is working, the foam flushing valve 271 is in the closed state to prevent foam from entering the foam flushing pipe 27. After the foam supply system finishes working, foam liquid will remain in the pipes within the foam supply system. By controlling the foam flushing valve 271 to open and controlling the pump foam unit 22 to operate, the remaining foam liquid in the pipes of the foam supply system can be flushed in a timely manner to prevent the foam liquid from corroding the pipes.

[0052] like Figure 8 As shown, in an embodiment of the present invention, the foam supply system S2 further includes a drain pipe 29, one end of which is connected to the outlet pipe of the pump foam unit 22, and the other end is connected to the outside. A drain control valve 291 for controlling the on / off state is also provided on the drain pipe. By providing the drain pipe, water used to flush 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 rinsing.

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

[0055] like Figure 3 and Figure 4 As shown, when the foam supply system S2 is in the tank-supply foam output mode, the foam in the foam storage tank 211a is output sequentially through the first foam pipeline 211, the pump foam unit 22, and the output control unit 23. If, after the pump foam unit 22 has been running for a period of time, the liquid level in the foam storage tank 211a is detected to be lower than a preset value, the pump foam unit 22 needs to be shut down, and personnel should be reminded to add foam liquid to the foam storage tank 211a to prevent the pump foam unit 22 from running dry for an extended period.

[0056] like Figure 5 As shown, when the foam supply system S2 is in the external suction-pumping foam working mode, external foam sequentially passes through the second foam pipeline 212, the foam pumping unit 22, and the foam pumping pipeline 24 into the foam storage tank 211a, thereby filling the foam storage tank 211a with foam liquid. When the liquid level in the foam storage tank 211a is higher than a certain set value, it indicates that the foam storage tank 211a has been filled with foam, at which point the foam pumping 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 supply foam working mode, the external foam is output sequentially through the second foam pipeline 212, the pump foam unit 22, and the external foam supply pipeline 26. In this mode, multiple 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 from the foam storage tank 211a is output sequentially through the first foam pipeline 211, the pump foam unit 22, and the external foam 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 flushing mode, the foam pump unit 22 draws 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. The flushed liquid can be discharged through the drain pipeline. In this mode, the foam pump unit 22 can operate at the default speed. In the water tank 111 supply mode, if the water volume in the water tank 111 is insufficient, the foam pump needs to be stopped to avoid the foam pump unit 22 running dry for a long time.

[0060] like Figure 1 As shown in the embodiment of the present invention, due to the presence of the flow regulating pipeline 25, when the pump foam unit 22 outputs foam, the opening degree of the flow regulating valve 251 can be adjusted accordingly by comparing the actual flow demand of the foam with the current output flow demand of the pump foam unit 22, thereby achieving precise 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 installed at the outlet of the pump foam unit 22.

[0061] In an embodiment of the present invention, if the pump foam unit 22 is detected to have no flow output for a continuous period of time after the pump foam unit 22 has been running for a period of time, the pump foam unit 22 can be controlled to stop, so as to avoid the pump foam unit 22 running idle for a long time.

[0062] In an embodiment of the present invention, when the output selection unit selects the first output port P1 for output, if the water pump unit 12 stops, the foam pump unit 22 also needs to be stopped to avoid foam contamination of 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 for storing clean water. A first water supply pipeline 112 is provided between the water tank 111 and the inlet of the pumping unit 12. A tank water supply valve 112a for controlling the on / off state is provided on the first water supply pipeline 112. By controlling the opening and closing of the tank water supply valve 112a, water can be supplied from the water tank 111 to the pumping unit 12.

[0064] like Figure 1 As shown, in an 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 pumping unit 12. The second water supply pipeline 113 is used to supply water from the outside to the inlet of the pumping unit 12, and an external water supply valve 113a for controlling the on / off state may also be provided on the second water supply pipeline 113.

[0065] Water can be drawn from the outside of the pump unit 12 and water can be drawn from the water tank 111 through the first water supply pipeline 112 and the second water supply pipeline 113.

[0066] like Figure 8 As shown, in an embodiment of the present invention, one end of the foam rinsing pipe 27 can be connected to the water tank 111, and the foam rinsing pipe 27 can be provided with an external water inlet. That is, the water source for the foam rinsing pipe 27 can come from the water tank 111 or from the outside.

[0067] like Figure 1 As shown, in an embodiment of the present invention, the pumping unit 12 may have two output water paths, one of which is connected to the spraying unit 13, and the other is connected to the water tank 111. Water can be supplied to the water tank 111 through the output water path connected between the water tank 111 and the pumping 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, which includes a direct water supply pipeline 141. One end of the direct water supply pipeline 141 is connected to external pressurized water, and the other end is connected to the outlet pipeline of the pump unit 12. When the pump unit 12 is in a stopped state, the foam pumped by the foam pump unit 22 flows directly to the outlet of the pump unit 12 and mixes with the water in the direct water supply pipeline 141 before being 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, thereby enabling emergency use of the system assembly even when the pump unit 12 fails.

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

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

[0071] In embodiments of the present invention, the valves on each pipeline can be electrically controlled valves or hydraulically controlled valves, and the system can be equipped with a controller. The controller can automatically control the corresponding valve switching state with one click according to the manually selected working mode, thereby realizing one-click operation.

[0072] In summary, the fire protection system assembly of the present invention, when outputting foam, switches the state of the output control unit 23 according to the operating state of the pump unit 12. This not only eliminates dependence on the operation of the pump unit 12, enabling independent foam output and joint output with the pump unit 12, but also reduces the operating pressure required for the foam pump unit 22 when used in conjunction with the pump unit 12. The fire protection system assembly of the present invention has multiple operating modes. In each mode, it can achieve precise control of foam flow output. In the external foam supply mode, it can easily supply foam to other fire trucks or fire equipment, achieving linkage with other fire trucks or fire equipment. The valves in the fire protection system assembly of the present invention can be controlled by signals, enabling one-button automatic mode switching of the system assembly, greatly simplifying the operation process.

[0073] To achieve the above objectives, the present invention also provides a fire-fighting device, wherein the fire-fighting device may be a fire truck, and the fire-fighting device includes the fire-fighting system assembly described above. Since the fire-fighting device adopts all the technical solutions of the above embodiments, it at least has the beneficial effects brought about by the above embodiments, and will not be repeated here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
