DETAILED DESCRIPTION

[0021] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-4 As shown, the utility model provides a simple automatic water sprinkler fire extinguishing system, including a water supply module 1, a connecting water pipe 2, a pressure gauge 3, a booster pump assembly 4, a water flow indicator 5, a main control system 6, a sprinkler module 7, a smoke detector 74 and an alarm device 8. The water supply module 1 is connected to the pressure gauge 3, the booster pump assembly 4, the water flow indicator 5 and the sprinkler module 7 in sequence through the connecting water pipe 2. The water flow indicator 5, the smoke detector 74, the alarm device 8, the booster pump assembly 4, the sprinkler module 7 and the main control system 6 are signal connected. The smoke detector 74 is used to detect whether a fire occurs in an area. The water flow indicator 5 installed on the connecting water pipe 2 is used to detect whether there is a water flow impact in the connecting water pipe 2 and send an electrical signal to the main control system 6. The main control system 6 is used to control the alarm device 8 and the booster pump assembly 4 to operate.

[0023] The pressure gauge 3 is used to detect the system water pressure to check whether there is any water leakage; the booster pump assembly 4 is used to increase the water pressure of the system. Because the tap water pressure is relatively low, in order to obtain a better fire extinguishing effect, the booster pump assembly 4 needs to be used for pressurization.

[0024] Furthermore, in order to realize that the sprinkler module 7 can automatically spray water to extinguish fire in case of fire, the sprinkler module 7 includes a sprinkler main pipe 71, a sprinkler branch pipe 72 and a fire sprinkler head 73, the sprinkler main pipe 71 and the sprinkler branch pipe 72 are connected in sequence, the sprinkler branch pipes 72 are spaced apart at different positions of the sprinkler main pipe 71, and a plurality of fire sprinklers 73 are spaced apart on the sprinkler branch pipe 72, and the fire sprinkler head 73 uses a 68-degree fire sprinkler head 73. When a fire occurs, hot smoke will be generated. When the smoke temperature around the sprinkler head reaches 68°C, the 68-degree fire sprinkler head 73 will burst, and the water of the system will be sprayed out from the sprinkler head to extinguish the fire.

[0025] Furthermore, in order to enable the water supply module 1 to supply water to the fire extinguishing system, the water supply module 1 includes a water supply source 11, a gate valve 12 and a water supply pipeline 13. The water supply source 11 is connected to the tap water pipeline, and the water supply source 11 is connected to the connecting water pipe 2 through the water supply pipeline 13. The water supply pipeline 13 is also provided with a gate valve 12 for opening and closing the water supply pipeline 13 during maintenance.

[0026] Furthermore, in order to prevent the water of the fire extinguishing system from flowing back and contaminating the tap water, a check valve 14 for preventing the water from flowing back is also installed on the connecting water pipe 2.

[0027] Furthermore, the water supply module 1 also includes a water pump connector 15, one end of which is connected to the water supply pipeline 13 of the water supply module 1, and the other end of which is connected to the water pump of the fire truck. The water pump connector 15 is a device used in conjunction with the water pump in firefighting. When a fire occurs, the water pump of the fire truck can be quickly and conveniently connected to the firefighting equipment in the building through the interface of the connector, and water can be delivered for pressurization, so that the firefighting equipment in the room can obtain sufficient pressure water source.

[0028] Furthermore, the alarm device 8 includes an audible and visual alarm and a wireless module. The audible and visual alarm, the wireless module and the main control system 6 are electrically connected. The main control system 6 sends the alarm information to an external remote terminal through the wireless module for warning.

[0029] Furthermore, it also includes a terminal water testing device 9, which includes a water testing joint 91, a water testing pressure gauge 92 and a water testing detection valve 93. The water testing joint 91 is installed at the end of the water pipe 2, and the water testing joint 91 is also equipped with a water testing pressure gauge 92 and a water testing detection valve 93. The terminal water testing device 9 is generally installed in a toilet or a convenient place for drainage, and is used to simulate the burst of the sprinkler, test whether the system is normal, and measure the fire extinguishing water pressure.

[0030] The terminal water test device 9 is used to test the reliability of the system: by simulating the water spray volume of the terminal nozzle, the system's startup ability under the most unfavorable conditions is tested, thereby judging the reliability of the entire system. Test the patency of the pipe network: through the water release test, check whether the pipe network is unobstructed and ensure that the water flow can pass normally.

[0031] According to the design specifications, the most unfavorable end must have a working pressure of 0.05MPa. The flow coefficient of the standard nozzle commonly used in the market is K=80. According to the design specifications, the most unfavorable end must have a working pressure of 0.05MPa. Thus, through calculation, the flow rate of this nozzle reaches 1.00L / s. Therefore, when the terminal water test device 9 is turned on at the above-mentioned working pressure of 0.05MPa, the pipe network flow rate can also reach 1.00L / s, so that the water flow indicator 5 and the alarm device 8 can start working, thereby achieving the purpose of testing the reliability of the system.

[0032] The method for using the above-mentioned simple automatic sprinkler fire extinguishing system comprises the following steps:

[0033] S1, when a fire occurs and the smoke temperature around the fire sprinkler 73 reaches 68°C, the fire sprinkler 73 bursts and water from the sprinkler system is ejected from the fire sprinkler 73;

[0034] S2, the water flow indicator 5 detects the water flow impact in the connected water pipe 2, and sends a corresponding electrical signal to the main control system 6, and the main control system 6 controls the booster pump assembly 4 to start, so as to increase the water pressure of the system;

[0035] S3, the main control system 6 controls the alarm device 8 to turn on, and emits an audible and visual alarm to remind the on-site personnel of the fire;

[0036] S4, the main control system 6 sends an alarm message to the external local fire station and the householder's mobile phone through the wireless module to notify the relevant staff and the householder of the fire.

[0037] When a fire occurs, the fire sprinkler bursts, and water from the sprinkler system sprays out from the fire sprinkler to extinguish the fire. The water flow indicator detects the impact of water flow in the connected water pipe, and the main control system controls the booster pump assembly to start pressurizing, and the sound and light alarm turns on to warn. The main control system sends alarm information to the external fire station and the user's mobile phone through the wireless module to warn, making the response faster and more effective.

[0038] The utility model solves the problem of fire rescue and escape difficulties in urban villages and rural areas. The simple automatic water sprinkler fire extinguishing system can also effectively control the spread of fire, buying more time for people to escape and rescue.
