Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water pipe pressure detection mechanism. Background Art

[0002] Fire-fighting water pipes are widely used in various scenarios, including building fire-fighting, industrial fire-fighting, and traffic fire extinguishing. In building fire-fighting, fire-fighting water pipes are widely used in buildings such as high-rise buildings, public places, and residences to ensure the smooth progress of fire extinguishing work. In industrial fire-fighting, fire-fighting water pipes include fire hoses, which can quickly transmit water sources in places such as dangerous goods warehouses, chemical plants, and oil depots for emergency fire extinguishing. "Fire-fighting facilities shall be comprehensively inspected at least once a year to ensure they are in good condition and effective. The inspection records shall be complete and accurate for filing for future reference", which clarifies the necessity of annual inspection of building fire-fighting facilities. Currently, the equipment for fire-fighting facility inspection mainly consists of a water gun and a pressure gauge.

[0003] For example, in a Chinese patent: the application number is 2021223463215, and the patent name is a fire-fighting water pipe water pressure detection device, "including: a housing; connecting pipes are respectively communicated at both ends of the housing, and a water pressure detection head is installed above the housing; a pressure relief protection mechanism is installed inside the housing, and the pressure relief protection mechanism is cooperatively arranged with a pressure relief pipe, and the pressure relief pipe is arranged below the housing". In the above technology, the pressure gauge is directly installed on the fire-fighting pipe, which not only has a high cost, but also is difficult to repair and replace after long-term use of the pressure. When repairing, the main valve of the fire-fighting pipe needs to be closed, and then the connection mechanism between the fire-fighting pipe and the pressure gauge needs to be disassembled. Moreover, there is already water pressure inside the fire-fighting pipe. Once the connection mechanism between the fire-fighting pipe and the pressure gauge is disassembled, the water pressure will spray out from the fire-fighting pipe, greatly increasing the difficulty of repair.
