Description

Technical Field

[0001] This utility model relates to the field of fire protection, and in particular to an antifreeze fire protection system. Background Technology

[0002] Existing fire protection systems generally use water for fire extinguishing, and a certain amount of water remains in the pipes of the fire protection system. In the cold season, the water remaining in the pipes is prone to freezing and blocking the pipes, which prevents water from flowing out of the pipes and affects the normal use of the fire extinguishing function.

[0003] In view of the above problems, it is necessary to study an antifreeze fire protection system that can work normally in the cold season. Utility Model Content

[0004] The purpose of this invention is to provide an antifreeze fire protection system that can perform fire extinguishing operations normally during the cold season.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An antifreeze fire protection system includes a controller, an insulated box, a water storage tank, a water supply pump, a fire-fighting water outlet device, and an antifreeze water outlet device. The controller, water storage tank, water pump, and antifreeze water outlet device are housed inside the insulated box. The antifreeze water outlet device includes a water outlet valve, an air inlet valve, an output pipeline, and a tee connector. The first end of the tee connector is connected to the water outlet end of the water outlet valve, the second end of the tee connector is connected to the air outlet end of the air inlet valve, and the third end of the tee connector is connected to the input end of the output pipeline. The water outlet end of the water supply pump is connected to the water inlet end of the water outlet valve, and the water inlet end of the water supply pump is connected to the water storage tank. The controller is electrically connected to the water supply pump. The fire-fighting water outlet device is located outside the insulated box and is connected to the output end of the output pipeline.

[0007] The fire-fighting water outlet device includes an automatic water outlet device suspended in the air. The automatic water outlet device includes multiple automatic sprinklers and an automatic water outlet pipeline connected to each automatic sprinkler. The automatic sprinklers are fire sprinkler heads, and the automatic water outlet pipeline is connected to the output end of the output pipeline. The water supply pump is a booster pump with automatic start and stop function.

[0008] The aforementioned antifreeze fire protection system also includes a fire detection device, which is located outside the insulation box and is electrically connected to the controller.

[0009] The fire-fighting water outlet device includes an electrically controlled water outlet device suspended in the air. The electrically controlled water outlet device includes multiple water outlet nozzles and electrically controlled water outlet pipelines connected to each automatic nozzle. The electrically controlled water outlet pipelines are connected to the output end of the output pipeline through a water outlet solenoid valve, and the water outlet solenoid valves are electrically connected to the controller.

[0010] The water outlet nozzle is an atomizing nozzle and / or a spray nozzle.

[0011] The fire detection device includes at least one of the following: a heat and smoke detector, a flame detector, an infrared temperature detector, and a heat-sensing cable.

[0012] The fire-fighting water outlet device includes a charging cabinet water outlet device, which is connected to the output end of the output pipeline.

[0013] The inlet end of the outlet valve is connected to the outlet end of the water supply pump via a first pressure gauge; the second end of the three-way connector is connected to the outlet end of the air inlet valve via a second pressure gauge; a check valve is connected in series between the first pressure gauge and the outlet end of the water supply pump, and a check valve is connected in series between the second pressure gauge and the second end of the three-way connector.

[0014] The insulation box is equipped with a temperature-controlled heater, which is electrically connected to the controller.

[0015] The water storage tank is equipped with a water tank heater, which is electrically connected to the controller.

[0016] The aforementioned antifreeze fire protection system also includes a water recovery device, which includes a water recovery tank and a water recovery pump. The water recovery tank is located outside the insulation box, the inlet of the water recovery pump is connected to the water recovery tank, and the outlet of the water recovery pump is connected to the water storage tank.

[0017] After adopting the above solution, the antifreeze fire protection system of this utility model has an antifreeze water outlet device, which enables the antifreeze fire protection system of this utility model to have an antifreeze maintenance operation mode. The antifreeze maintenance operation mode is as follows: First, close the water outlet valve, then open the air inlet valve and input air into the output pipeline through the air inlet valve, so that the output pipeline and the fire water outlet device reach a certain air pressure, and finally, close the air inlet valve and then open the water outlet valve. This invention, through the aforementioned anti-freeze maintenance method, ensures that the output pipeline and the fire-fighting water outlet device reach a certain air pressure, making it difficult for water to enter them. Even with minimal water flow, the output pipeline and fire-fighting water outlet device are not blocked due to internal water freezing. Furthermore, both the water storage tank and the water supply pump are housed in an insulated enclosure, which prevents the water in these components from freezing. Thus, even in severe cold weather, the water supply pump can still draw water from the storage tank to the fire-fighting water outlet device, ensuring normal fire-fighting operations.

[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0038] like Figures 1 to 7 As shown, this utility model discloses an anti-freezing fire protection system, which includes a controller A, an insulated box B, a water storage tank C, a water supply pump D, a fire-fighting water outlet device, and an anti-freezing water outlet device E; the controller A, water storage tank C, water pump, and anti-freezing water outlet device E are installed inside the insulated box B; the anti-freezing water outlet device E includes a water outlet valve E1, an air inlet valve E2, an output pipe E3, and a three-way connector E4, the first end of the three-way connector E4 being connected to the water outlet end of the water outlet valve E1, and the third end being connected to the outlet end of the water outlet valve E1. The second end of the connector E4 is connected to the air outlet of the air inlet valve E2, and the third end of the tee connector E4 is connected to the input end of the output pipeline E3; the outlet of the water supply pump D is connected to the inlet of the outlet valve E1, and the inlet of the water supply pump D is connected to the water storage tank C; the controller A is electrically connected to the water supply pump D; the fire-fighting water outlet device is installed outside the insulation box B, and the fire-fighting water outlet device is connected to the output end of the output pipeline E3. The fire-fighting water outlet device is used to discharge water for fire extinguishing operations.

[0039] The antifreeze fire protection system of this utility model has an antifreeze water outlet device E, which enables the antifreeze fire protection system of this utility model to have an antifreeze maintenance operation mode. The antifreeze maintenance operation mode is as follows: First, close the water outlet valve E1. Then, open the air inlet valve E2 and input air into the output pipeline E3 through the air inlet valve E2, so that the output pipeline E3 and the fire water outlet device reach a certain air pressure. Finally, close the air inlet valve E2 and then open the water outlet valve E1. This invention, through the aforementioned anti-freeze maintenance method, ensures that the output pipe E3 and the fire-fighting water outlet device reach a certain air pressure. This makes it difficult for water to enter the output pipe and the fire-fighting water outlet device, resulting in very little water flow inside them. This prevents blockages caused by freezing of the internal water in the output pipe E3 and the fire-fighting water outlet device. Furthermore, both the water storage tank C and the water supply pump D are housed in an insulated box B, which provides insulation and prevents the water in the water storage tank C and the water supply pump D from freezing. Thus, even in severe cold weather, the water supply pump D can still draw water from the water storage tank C to the fire-fighting water outlet device for dispensing, ensuring normal fire-fighting operations.

[0040] In an embodiment of this utility model, the anti-freezing fire protection system further includes a fire detection device F. The fire detection device F is located outside the insulation box B and is electrically connected to the controller A. Specifically, the fire detection device F can be installed on the roof 1 of the carport (i.e., this utility model can be used for carport fire protection). The roof 1 is supported by columns 2. The fire detection device F includes a heat and smoke detector F1, a flame detector F2, and an infrared temperature detector F3. The heat and smoke detector F1, the flame detector F2, and the infrared temperature detector F3 can all send signals to the controller A when a fire occurs (such as smoke or even open flame). It should be noted that the fire detection device F of this utility model is not limited to simultaneously including a heat and smoke detector F1, a flame detector F2, and an infrared temperature detector F3. The fire detection device F can include at least one of the heat and smoke detector F1, a flame detector F2, an infrared temperature detector F3, and a temperature sensing cable. In this way, the controller A can detect whether a fire problem has occurred through the fire detection device F, and the temperature sensing cable can also send a signal to the controller A when a fire problem occurs (such as smoke or even open flame).

[0041] In an embodiment of this utility model, the fire-fighting water outlet device includes an automatic water outlet device G suspended in mid-air. Specifically, the automatic water outlet device G can be installed on the roof 1 of a carport. The automatic water outlet device G includes multiple automatic sprinkler heads G1 and automatic water outlet pipes G2 connected to each automatic sprinkler head G1. The automatic sprinkler heads G1 are fire sprinkler heads, and the automatic water outlet pipes G2 are connected to the output end of the output pipe E3. The water supply pump D is a booster pump with automatic start / stop function. When a fire occurs in the environment where the automatic water outlet device G is located, the automatic sprinkler heads G1 will automatically rupture and open due to heat, causing the automatic water outlet pipes G2 to depressurize and causing the water supply pump D to automatically operate. The water supply pump D then draws water from the water storage tank C to the automatic sprinkler heads G1 of the automatic water outlet device G, and the water is discharged from the ruptured automatic sprinkler heads G1 to extinguish the fire. In this invention, when the air inlet valve E2 is opened and air is input into the output pipe E3 through the air inlet valve E2 so that the output pipe E3 and the fire water outlet device reach a certain air pressure, and then the water outlet valve E1 is opened, the water supply pump D will automatically shut off due to the pressure inside the output pipe E3 and the fire water outlet device.

[0042] In an embodiment of this utility model, the fire-fighting water outlet device further includes a suspended electrically controlled water outlet device H. The electrically controlled water outlet device H includes multiple water outlet nozzles H1 and electrically controlled water outlet pipelines H2 connected to each automatic nozzle G1. The electrically controlled water outlet pipeline H2 is connected to the output end of the output pipeline E3 via a water outlet solenoid valve H3. The water outlet solenoid valve H3 is electrically connected to the controller A. When the controller A detects a fire through the fire detection device F, the controller A correspondingly controls the water outlet solenoid valve H3 to open, and the water supply pump D operates to draw water from the water storage tank C to the water outlet nozzles H1 of the electrically controlled water outlet device H, whereby the water outlet nozzles H1 discharge water to extinguish the fire. The water outlet nozzles H1 can be atomizing nozzles and / or spray nozzles.

[0043] In an embodiment of this utility model, the fire-fighting water outlet device further includes a charging cabinet water outlet device I, which is connected to the output end of the output pipe E3. The charging cabinet water outlet device I is used to extinguish the fire in the charging cabinet 5. The spray pipe I1 of the charging cabinet water outlet device I is connected to the output end of the output pipe E3. When the charging cabinet 5 catches fire, the water supply pump D operates, causing water in the water storage tank C to be drawn from the spray pipe I1 of the charging cabinet water outlet device I and sprayed out by the spray pipe I1, thereby extinguishing the fire in the charging cabinet 5.

[0044] In an embodiment of this utility model, the anti-freezing fire protection system further includes a water recovery device J, which can recover the water output from the fire hydrant to the water storage tank C. Specifically, the water recovery device J includes a recovery tank J1 and a recovery pump J2. The recovery tank J1 is located outside the insulation box B, and the recovery pump J2 can be located inside the insulation box B. The inlet of the recovery pump J2 is connected to the recovery tank J1, and the outlet of the recovery pump J2 is connected to the water storage tank C. When the controller A detects a fire through the fire detection device F, the water supply pump D draws water from the water storage tank C to the fire hydrant, and the fire hydrant discharges water. The water discharged from the fire hydrant can flow back to the recovery tank J1, and the controller A controls the recovery pump J2 to pump the water in the recovery tank J1 back to the water storage tank C, thereby realizing water recycling and helping to save water resources. The inlet of the recycling water pump J2 can be equipped with a filter J3 to prevent impurities in the recycling water tank J1 from entering the recycling water pump J2 and damaging it. The recycling water tank J1 can be set on the ground 3 under the carport. The ground 3 under the carport can be equipped with a water collection ditch 31. The opening of the water collection ditch 31 is equipped with a permeable grid 4 to reduce the entry of impurities into the water collection ditch 31. The recycling water tank J1 can be connected to the recycling water tank J1 through a water collection solenoid valve J4. Under normal conditions, the water collection solenoid valve J4 is closed, so that the water flow (usually rainwater) in the water collection ditch 31 does not enter the recycling water tank J1. However, when the fire hydrant is activated due to a fire, the controller A controls the water collection solenoid valve J4 to open, so that the water in the water collection ditch 31 flows into the recycling water tank J1 through the water collection solenoid valve J4.

[0045] In an embodiment of this utility model, the inlet of the outlet valve E4 is connected to the outlet of the water supply pump D via a first pressure gauge E5; the second end of the tee connector E4 is connected to the outlet of the air inlet valve E2 via a second pressure gauge E6. The first pressure gauge E5 and the second pressure gauge E6 can be used to confirm the air pressure inside the output pipeline E3 and the fire-fighting water outlet device. A check valve can be connected in series between the first pressure gauge E5 and the outlet of the water supply pump D, and a check valve can also be connected in series between the second pressure gauge E6 and the second end of the tee connector E4. The check valves can prevent water and air from flowing back.

[0046] In this embodiment of the invention, the insulation box B is equipped with insulation cotton (not shown) to ensure its insulation function. A temperature-controlled heater B1 is installed inside the insulation box B, and is electrically connected to the controller A. When the temperature inside the insulation box B is too low, the temperature-controlled heater B1 operates to heat the environment inside the insulation box B, ensuring stability. Furthermore, a water tank heater is installed in the water storage tank C, and is electrically connected to the controller A. When the water temperature in the water storage tank C is too low, the water tank heater operates to heat the water in the water storage tank C, preventing the water temperature from becoming too low. Additionally, an uninterruptible power supply (UPS) B2 can be installed in the insulation box B to provide power and ensure the reliable operation of the anti-freeze fire protection system of this invention. The output pipe E3 can be extended in an "S" shape to increase the effective length of the output pipe E3 within the insulation box B, effectively preventing the water in the output pipe E3 from freezing.
