[0002] The automatic sprinkler fire extinguishing detection system is mainly used to detect the roof water spray system, which is a system that sprays water outward when smoke or open flame is detected.

[0003] During testing, it is necessary to check whether the water can be sprayed out normally to determine whether it has a normal fire extinguishing function. In some cases, although the water can be sprayed out normally, if the water flow is too small or the water pressure is insufficient, it is still difficult to form a fire extinguishing capability. Therefore, the existing testing methods are not perfect and are prone to safety hazards. Utility Model Content

[0032] An automatic sprinkler fire extinguishing detection system includes a timing module, a volume detection module, and a control module. The timing module measures the automatic spraying time of the sprinkler system and generates a time signal. The volume detection module detects the volume of water sprayed by the sprinkler system and generates a volume signal. The control module receives the time signal and the volume signal. The control module is a computer. The timing module times the spraying time of the sprinkler system, and the volume detection module detects the volume of water sprayed in real time. Therefore, the time and volume signals received by the control module represent the volume of water sprayed by the sprinkler system within a certain time period, allowing the system to detect whether the volume of water sprayed by the sprinkler system meets the requirements, thus determining whether the automatic sprinkler fire extinguishing system is qualified. For example, if the volume of water sprayed within 10 seconds is less than the industry requirement, the system is considered unqualified.

[0033] Specifically, the timing module uses a stopwatch timer.

[0034] Specifically, the volume detection module includes a water storage component and a level gauge. The water storage component forms a water storage chamber, and the cross-sectional area of ​​the water storage chamber is the same along its height. The level gauge is used to detect the water level in the water storage chamber; the level gauge is signal-connected to the control module. After the level gauge detects the water level in the water storage chamber, it can calculate the volume of water in the water storage chamber using the cross-sectional area of ​​the water storage chamber and the water level height, thus obtaining the volume of water sprayed outward by the water spray system. The calculation method involves obtaining the specific water level height using the level gauge signal, and then the control module uses a multiplier to perform a multiplication operation to obtain the specific volume.

[0035] Specifically, in some embodiments, the volume detection module includes: a water receiving component 1, a laser rangefinder 2, a piston block 3, and an elastic structure. The water receiving component 1 forms a water receiving chamber, and the cross-sectional area of ​​the water receiving chamber is the same along its height. The water receiving component 1 is a measuring cylinder. The piston block 3 abuts against the inner wall of the water receiving chamber and is slidably connected. The elastic structure is located below the piston block 3. The laser rangefinder 2 is used to detect the distance between the piston block 3 and the bottom surface of the water receiving chamber. The elastic structure is used to make the piston block 3 abut against the nozzle of the sprinkler system. The upper end of the water receiving chamber is sealed by the roof where the sprinkler system is located. The rangefinder is signal-connected to the control module. This allows the piston block 3 to move immediately after the sprinkler system sprays water outwards, avoiding the delay caused by water falling through the air, resulting in more accurate detection.

[0036] Specifically, the elastic structure uses spring 4.

[0037] In other embodiments, the elastic structure includes an air pump 5 and an air guide pipe 6. The air pump 5 is mounted on a fixed frame 7, and the water receiving component 1 is mounted on the fixed frame 7. The air guide pipe 6 communicates with the water receiving chamber below the piston. By injecting air into the water receiving chamber below the piston block 3 using the air pump 5, the piston block 3 is subjected to an upward force. This upward force can be controlled by the air pump 5, thereby allowing for the detection of the water pressure of the sprinkler system to a certain extent. If the water pressure is low, the upward force on the piston block 3 will be large enough to prevent the piston block 3 from moving downward.

[0038] Specifically, a pressure detector is installed above the piston block 3.

[0039] Specifically, the upper part of the water-receiving component 1 forms an abutment portion for contacting the roof. The abutment portion uses an elastic pad. The purpose is to prevent leakage.
