Description

Technical Field

[0001] The utility model relates to the technical field of water testing devices, in particular to a fine water mist terminal water testing device for fire fighting. Background Art

[0002] A firefighting terminal water test device is a device used to test the water source and water supply capacity of a firefighting system. It typically includes a pressure gauge, valves, and a drainage device. This terminal water test device is typically installed at the sprinkler head at the most unfavorable point in the system pipe network. This most unfavorable sprinkler head typically has the lowest pressure and smallest flow rate in the system. Testing here ensures that the system can still provide sufficient water flow and flow under the most extreme conditions, providing more reliable protection for the effectiveness and safety of the firefighting system.

[0003] In the prior art, for example, a Chinese patent with the publication number CN216676819U, titled "A Water Mist Terminal Water Testing Device," discloses a technical solution that states that the device is provided with a positioning pin. When the height of the water mist terminal port is different, the positioning pin is pulled, and the positioning pin moves out of the positioning hole on the outer wall of the reel. At this time, the knob is turned, and the knob drives the reel on the outer wall of the shaft to rotate, thereby reeling in and releasing the traction rope, making it easier to adjust the height of the water testing device body. By comparison with related technical fields and similar technical solutions, when the terminal water testing device is in use, the water flow may contain impurities such as mud, sand, and rust. These impurities may cause blockage of the pressure gauge water inlet and the water testing joint, affecting the use of the water testing device. Utility Model Content

[0007] Furthermore, the auxiliary mechanism includes a connecting rod, a rotating handle and a water outlet. The connecting rod is fixedly mounted on the upper end of the rotating plate, the connecting rod is rotatably connected to the horizontal water pipe, and the upper end of the connecting rod is fixedly mounted with a rotating handle; the water outlet is opened at the lower end of the horizontal water pipe, the water outlet is arranged between the rotating plate and the vertical water pipe, and a sealing cover is threadedly mounted on the lower end of the water outlet; when regularly cleaning impurities in the test water pipe, close the stop valve, rotate the rotating handle, and the rotating handle drives the rotating plate to rotate through the connecting rod so that the axis of the rotating plate and the axis of the horizontal water pipe are perpendicular, unscrew the sealing cover, and the impurities in the test water pipe can be discharged from the water outlet as the water flows through both sides of the rotating plate.

[0008] Furthermore, the auxiliary mechanism also includes a mounting frame, which is fixedly mounted on the center of the rotating plate near the vertical water pipe.
