Description

Technical Field

[0001] This utility model relates to the field of pipe testing, specifically a leak detection device for fire protection pipes. Background Technology

[0002] Fire protection piping refers to the piping materials used in fire protection facilities such as fire water supply systems, fire hydrant systems, and automatic sprinkler systems. The main function of fire protection piping is to transport fire-fighting water, ensuring that water can be quickly and reliably delivered to the required location when a fire occurs, thereby effectively extinguishing the fire and controlling its spread. With the advancement of building technology and the increasing demands for fire protection, the types, performance, and application scenarios of fire protection piping are constantly developing and improving.

[0003] When a leak occurs in fire protection pipes, an on-site investigation can be conducted, including reviewing the water supply network diagram, interviewing relevant personnel, and conducting a comprehensive inspection of the pipe layout, materials, and surrounding environment. By observing phenomena such as wet roads, early snow melting in winter, lush vegetation, and continuous flow of clean water in drainage ditches, the leaking area can be initially determined. Then, based on the approximate leaking area, the search can continue until the leaking location of the pipe is found.

[0004] When faced with pipe leaks, the approximate location of the leak can only be determined after the leak has been going on for some time or after an abnormality has occurred. Furthermore, confirming the exact location takes a lot of time and is extremely inefficient. Therefore, it is necessary to design a fire-fighting pipe leak detection device that can detect leaks efficiently. Utility Model Content

[0008] The utility model further sets up, the surface of limiting inclined pulley is arc, the direction of limiting inclined pulley is not orthogonal alignment with pipeline, the material of limiting inclined pulley is rubber, the one end of pipeline away from main detection device is installed with accessory detection device, the inner wall edge of accessory detection device is tangent with pipeline internal edge and expands outward.

[0009] By adopting the above technical scheme, due to the inclined design of the limiting inclined pulley, the runner rotates along the inclined direction of the limiting inclined pulley during the forward movement of the runner until the runner moves to the end of the pipeline, with the rotation of the runner, the limiting inclined pulley on the runner at the communication place of the accessory detection device and the pipeline will stretch due to the loss of the restraint of the inner wall of the pipeline, at this time, the outward stretching limiting inclined pulley cannot return to the pipeline, under the impact of the water flow and the cooperation of the limiting inclined pulley, the runner will rotate along the corresponding extended limiting inclined pulley until the limiting inclined pulley is separated from the pipeline, thereby completing the recovery of the runner.

[0012] The utility model further sets up, the side of main detection device and accessory detection device away from each other all is installed with second detection fan blade, and the mutual cooperation between two second detection fan blades.

[0013] By adopting the technical scheme, the second detection fan blade can detect the flow rates on both sides of the pipeline, so as to determine the water leakage pipeline, and after detecting the water leakage pipeline, the corresponding pipeline is directly detected, and the pipeline leakage detection efficiency is increased.

[0014] In summary, the utility model mainly has the following beneficial effects:
