[0037] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0038] like Figures 1 to 6 As shown, the utility model discloses an automatic fire sprinkler system for a carport, which includes a water storage tank A, a master controller B, a water supply pump C with an automatic start-stop function, and at least one fire sprinkler unit; the fire sprinkler unit includes a fire sprinkler assembly D, an atomizing sprinkler assembly E and a fire reaction device F arranged adjacent to each other, and the fire reaction device F can send a signal to the master controller B when a fire problem occurs in the corresponding area of ​​the fire sprinkler unit;

[0039] The fire sprinkler assembly D comprises a plurality of fire sprinklers D1 installed on the lower side of the ceiling 11 of the carport 1, and a fire sprinkler pipe D2 connected to each fire sprinkler D1 of the fire sprinkler assembly D. The fire sprinkler pipe D2 is connected to the outlet of the water supply pump C. The response time index RTI of the fire sprinkler D1 is ≤50 (m*s), so that the fire sprinkler D1 can respond quickly. The atomizing spray assembly E comprises a plurality of atomizing sprayers E1 installed on the lower side of the ceiling 11 of the carport 1, And an atomizing spray pipeline E2 connecting each atomizing nozzle E1 of the atomizing spray assembly E, the atomizing spray pipeline E2 is connected to the water outlet of the water supply pump C through the spray solenoid valve E3; the water inlet of the water supply pump C is communicated with the inner cavity of the water storage tank A, the water supply pump C can specifically adopt a pressure-type self-priming pump, and the structure of the water supply pump C with automatic start and stop function is the prior art and will not be repeated here; the main controller B is electrically connected to the fire response device F and the spray solenoid valve E3 respectively.

[0040] The working principle of the automatic fire sprinkler system of a carport of the utility model is as follows: when a fire occurs in a vehicle parked under the ceiling 11 of the carport 1 and corresponding to a certain fire sprinkler unit, the temperature of the burning vehicle rises rapidly, causing the fire sprinkler head D1 of the fire sprinkler assembly D of the fire sprinkler unit corresponding to the burning vehicle to burst. After the fire sprinkler head D1 bursts, the pressure at the water outlet of the water supply pump C drops, causing the water supply pump C to start automatically. In this way, the water supply pump C draws water from the water tank A to the fire sprinkler head D1 of the fire sprinkler assembly D and sprays it out from the fire sprinkler head D1, thereby automatically spraying water to extinguish the fire on the burning vehicle, making the fire extinguishing more timely and effective, thereby ensuring fire safety; and when the fire sprinkler is parked under the ceiling 11 of the carport 1, the fire sprinkler head D1 of the fire sprinkler assembly D is automatically sprayed to extinguish the fire on the burning vehicle. When a fire problem (such as smoke or even open flame) occurs in a vehicle below 11 and corresponding to a certain fire sprinkler unit, the main controller B detects the fire problem through the fire response device F of the fire sprinkler unit corresponding to the burning vehicle, and then the main controller B controls the spray solenoid valve E3 of the atomizing spray assembly E of the fire sprinkler unit corresponding to the burning vehicle to open. At this time, the water supply pump C can also draw water in the water tank A to the atomizing nozzle E1 of the atomizing spray assembly E, so that the atomizing nozzle E1 sprays water mist to act on the smoke generated by the fire, thereby settling and cooling the smoke, reducing the harm caused by the smoke, and the water mist can also adhere to the vehicle to reduce the spread of the fire, further ensuring fire safety.

[0041] In an embodiment of the utility model, the fire sprinkler head D1 of the fire sprinkler assembly D can be equipped with a heat collecting cover D3. When a fire occurs in a vehicle parked under the roof 11 of the carport 1, the heat collecting cover D3 can allow more heat to converge on the fire sprinkler head D1 and accelerate the bursting speed of the fire sprinkler head D1, thereby accelerating the water discharge speed of the fire sprinkler head D1 and further ensuring fire safety.

[0042] In an embodiment of the utility model, the fire response device F of the fire sprinkler unit includes a water flow sensor F1 connected in series with the fire sprinkler pipeline D2 of the fire sprinkler assembly D of the fire sprinkler unit; when a vehicle parked under the ceiling 11 of the carport 1 and corresponding to a certain fire sprinkler unit has a fire problem, the temperature of the burning vehicle rises rapidly, causing the fire sprinkler head D1 of the fire sprinkler assembly D of the fire sprinkler unit corresponding to the burning vehicle to burst. After the fire sprinkler head D1 bursts, the pressure of the water outlet of the water supply pump C will drop, causing the water supply pump C to start automatically, so that the water supply pump C will draw water from the water tank A to the fire sprinkler head D1 of the fire sprinkler assembly D and spray it out by the fire sprinkler head D1. At this time, the main controller B detects the flow of water through the water flow sensor F1 of the fire sprinkler unit corresponding to the burning vehicle and determines that a fire problem has occurred, and then the main controller B detects the occurrence of a fire problem through the water flow sensor F1.

[0043] In the embodiment of the utility model, the fire response device F of the fire sprinkler unit may also include a heat-sensitive smoke fire detector F2, a flame detector F3 and an infrared temperature detector F4 installed on the lower side of the ceiling 11 of the carport 1; when a vehicle parked under the ceiling 11 of the carport 1 and corresponding to a certain fire sprinkler unit has a fire problem, at this time, the master controller B can detect the fire problem through the heat-sensitive smoke fire detector F2, the flame detector F3 and the infrared temperature detector F4 of the fire sprinkler unit corresponding to the vehicle on fire. It should be noted that the fire response device F of the utility model is not limited to including the water flow sensor F1, the heat-sensitive smoke fire detector F2, the flame detector F3 and the infrared temperature detector F4. The fire response device F only needs to include at least one of the water flow sensor F1, the heat-sensitive smoke fire detector F2, the flame detector F3 and the infrared temperature detector F4, and the master controller B can detect whether a fire problem occurs through the fire response device F.

[0044] In an embodiment of the utility model, an automatic fire sprinkler system for a carport of the utility model also includes a water recovery device G matched with a water tank A. The water recovery device G can be used to recover the water output by the fire sprinkler head D1 of the fire sprinkler assembly D and the atomizing nozzle E1 of the atomizing sprinkler assembly E to the water tank A, thereby realizing the recycling of water, which can effectively improve the fire extinguishing effect and save water resources.

When a fire occurs in a vehicle parked under the roof 11 of the carport 1, water output from the fire sprinkler head D1 of the fire sprinkler assembly D and the atomizer nozzle E1 of the atomizer sprinkler assembly E will flow to the water collection tank G1 and be collected by the water collection tank G1. The water in the water collection tank G1 can flow into the recovery water tank G2 under the action of gravity, and when the main controller B detects the water discharge of the water supply pump C through the fire response device F and determines that a fire occurs, the main controller B also controls the recovery water pump G23 to work after a preset delay time, so that the recovery water pump G23 draws water from the recovery water tank G2 into the water storage tank A.
