Description

Technical Field

[0001] The invention relates to the technical field of fire fighting, in particular to a sprinkler fire fighting device used for parking spaces in a parking lot. Background Art

[0002] With the acceleration of urbanization, the number of vehicles has increased dramatically, and the risk of fire in parking spaces has also increased. Traditional fire protection systems often require large-scale investment and construction, are complex, manually operated, have slow response times, and may not cover the main fire parts of the car. Therefore, it is particularly important to develop a parking space fire protection device that can have an independent water source, automatically detect fire conditions, and respond quickly. Summary of the invention

[0003] The purpose of the present invention is to provide a parking sprinkler fire-fighting device, which can be automatically started when a car spontaneously combusts, quickly and effectively extinguish the fire, and reduce the losses caused by the fire.

[0004] Technical solution: When a car in a parking space catches fire, the fire sensor receives a signal and connects to the controller. The battery in the controller starts the solenoid valve to open the water pipe valve, and the water in the water tank is sprayed out from the nozzle through the high-level water pipe and the ground water pipe to extinguish the fire. If the water level in the water tank is low and the water pressure is insufficient, the controller can start the water pump to pressurize the water flowing out of the water tank so that the water sprayed from the nozzle reaches the specified pressure, completing the work of extinguishing the fire of the burning car in the parking space. If the controller fails, the manual valve rod on the controller can be manually opened to open the valve in the controller to supply water to the water pipe and realize the nozzle spraying. If the car is on fire, the controller fails and no one comes to manually open the manual valve, the flame of the car will burn the pull rope, the pre-tightened spring in the controller will loosen the valve lock pin, the valve opens, and the water in the high-level water tank flows into the water pipe and is sprayed through the nozzle.

[0005] The present invention is further described below with reference to the accompanying drawings. Figure 1 It is a schematic diagram of the structure of the present invention.

[0006] To achieve the above object, the present invention provides the following technical solutions: The water tank bracket 3 is arranged at the rear part of the parking space for supporting the water tank 1. The car 11 can enter the water tank bracket 3 without affecting the use function of the parking space; the high-level water tank 1 is installed on the water tank bracket 3 for storing water for fire extinguishing, and fire spraying can be achieved by gravity alone; the water tank 1 is connected to the controller 4, and the controller 4 is provided with a control circuit, a battery, a valve, a manual control and a burn-off starting device for receiving the fire sensor 7 signal and controlling the opening of the water pipe valve. In an emergency, the water pipe valve can be opened manually or automatically by the burn-off pull rope 9; the valve in the controller 4 is connected to the high-level water pipe 5 located on the car and the ground water pipe 8 located at the bottom of the car, and the valve in the controller 4 controls the water in the water tank 1 to flow into the high-level water pipe 5 and the nozzle 6 in the ground water pipe 8; the nozzle 6 is installed on the high-level water pipe 5 and the ground water pipe 8 to spray water for fire extinguishing; the high-level water pipe 5 and the ground water pipe 8 is provided with a fire sensor 7 for detecting the spontaneous combustion of the car in the parking space and sending a signal to the circuit in the controller 4 in time; the pull rope 9 of the pull rope burning start device is installed between the controller 4 and the pull rope bracket 10, one end of the pull rope 9 is fixed to the pull rope bracket 10 in advance, and the other end is locked with the valve preload spring lock pin in the controller 4, and the valve is closed; when the controller 4 fails and no one manually opens the valve, the flame of the burning car 11 will burn the pull rope 9, the preload spring in the controller 4 rebounds, the spring lock pin is opened, the valve in the controller opens, and the water in the water tank 1 is sprayed out through the nozzle 6 on the high-level water pipe 5 and the ground water pipe 8; the water tank 1 is connected to the water pump 2 through the controller 4, and when the pressure sensor in the controller 4 senses insufficient water pressure, the water pump 2 is started to pressurize the water flowing out of the water tank 1, and the water is sprayed at a specified pressure through the nozzle 6 of the high-level water pipe 5 and the ground water pipe 8.

[0007] When the vehicle is in normal state, the battery in the controller 4 supplies power to the fire sensor 7 and the valve solenoid valve, as well as the water pump.

[0008] When a vehicle 11 in the parking space spontaneously ignites, the fire sensor 7 senses the heat and starts up, transmitting an electrical signal to the control circuit in the controller 4, which starts up the solenoid valve to open the valve. The water in the water tank 1 flows through the valve into the high-level water pipe 5 and the ground water pipe 8, and is sprayed out from the nozzle 6 to achieve spray fire extinguishing.

[0009] When the controller 4 fails, the rescuer can manually start the manual operating lever on the controller 4 to open the valve, so that the water in the water tank 1 flows into the high-level water pipe 5 and the ground water pipe 8 through the valve, and is sprayed out from the nozzle 6 to achieve spray fire extinguishing.

[0010] When the controller 4 fails and no one opens the valve manually, the flame of the burning car 11 will burn the pull rope 9, the preloaded spring in the controller 4 rebounds, the spring lock pin is opened, the valve in the controller opens, and the water in the water tank 1 is sprayed out through the nozzle 6 on the high-level water pipe 5 and the ground water pipe 8.

[0011] When the pressure sensor in the controller 4 senses that the water pressure is insufficient, the controller 4 starts the water pump 2 to increase the pressure of the water flowing out of the water tank 1, and sprays it through the nozzles 6 of the high-level water pipe 5 and the ground water pipe 8 at a specified pressure.

[0012] The parking space fire fighting device of the present invention has a simple structure, is easy to install and maintain, can automatically detect fire and respond quickly, can spray both on the top and bottom of a spontaneously combusting car, effectively improves the fire fighting safety of parking spaces in the parking lot and reduces the losses caused by fire.
