Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, and particularly relates to a water spraying end pressure detection device for fire-fighting detection. Background Technique

[0002] Fire protection facilities refer to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. People's awareness of fire protection is stronger, and these fire extinguishing devices need to detect the pressure at the water spraying end to determine whether the water pressure is sufficient; however, the existing detection devices use pressure sensors to detect the pressure at the water spraying end. But when the water pressure is too high, the impact force of the water is likely to damage the pressure sensor. At the same time, it is not convenient to fix the water spraying device parts, so that when spraying water, due to the too high water pressure, the device is likely to fall down and be damaged. Therefore, to solve the above problems, a water spraying end pressure detection device for fire-fighting detection is provided.

[0003] After retrieval, in the prior art, the Chinese patent with the patent publication number CN216117124U discloses "a water spraying end pressure detection device for fire-fighting detection, which relates to the technical field of fire-fighting equipment, including a limit frame, a support rod, and a base. The bottom end of the limit frame is connected to the support rod, and the bottom end of the support rod is connected to the base. The outer surface of the limit frame is connected with screws. The support rod is composed of an inner rod and an outer rod, and the outer rod is connected to the periphery of the inner rod. For this water spraying end pressure detection device for fire-fighting detection, the nozzle is placed in the limit frame, and the screw is rotated manually to drive one end of the screw to drive the fixing plate to fix the periphery of the nozzle, preventing the nozzle from detaching from the limit frame. And the shape of the abutting block is used to increase the stability of the screw and prevent the screw from swinging and loosening", but there are still the following defects:

[0004] (1) The existing pressure detection device only fixes the nozzle through screws and a fixing plate. This fixing method may not be stable enough. Especially when performing pressure detection, if the nozzle is subjected to a large impact force or vibration, the screws and the fixing plate may become loose, resulting in the nozzle detaching from the limit frame, affecting the detection accuracy and safety.

[0005] (2) The existing detection device fixes the pipeline in the vertical direction during use. In this way, when the water flow in the pipeline rushes out, it will directly face the downward ground, which may cause a counter impact force, resulting in inaccurate detection effect of the detection device.

[0006] Therefore, we make improvements on this and propose a water spraying end pressure detection device for fire-fighting detection. Content of the Utility Model

[0007] The purpose of the present utility model is as follows: In view of the existing pressure detection device that only fixes the nozzle through screws and fixing plates at present, this fixing method may not be firm enough.

The existing detection device fixes the pipeline in the vertical direction during use, so that when the water flow in the pipeline rushes out, it will directly face the downward ground, which may cause a reaction force and lead to inaccurate detection results of the detection device.
