Description

Technical Field

[0001] The utility model relates to the technical field of anti-leakage detection of building water supply and drainage pipelines, in particular to an anti-leakage detector for building water supply and drainage pipelines. Background Art

[0002] Building water supply and drainage pipes are piping systems used for water supply, drainage and wastewater discharge in buildings. In building water supply and drainage systems, anti-leakage detectors are required to regularly perform anti-leakage detection on the water supply and drainage pipes. Small leaks can be discovered and repaired in time to prevent them from developing into larger problems, thereby maintaining the integrity of the building and preventing potential long-term damage.

[0003] The Chinese patent "Anti-leakage detection device for municipal building drainage pipes" authorization announcement number "CN217505087U" realizes that the anti-leakage detection device is fixed inside the drainage pipe through a worm, a rotating cylinder, a worm wheel, a first threaded cylinder and a first screw, making it more convenient to fix the anti-leakage detection device in the drainage pipe.

[0004] In the above detection of the drainage pipe, since the drainage pipe contains impurities and water and the first screw is mostly exposed, the first screw contacts the impurities and water, which easily increases the wear between the first screw and the fixed box, thereby reducing the service life of the anti-leakage detector.

[0005] Therefore, an anti-leakage detector for building water supply and drainage pipelines is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0025] When it is necessary to conduct anti-leakage detection on the building water supply and drainage pipeline, the fixing cylinder 1 is placed in the pipeline through the handle 218, and the rotating rod 27 is rotated. The rotating rod 27 drives the first bevel gear 21 to rotate, and the first bevel gear 21 drives the four second bevel gears 22 to rotate. The second bevel gear 22 drives the first screw rod 23 to rotate, and the first screw rod 23 drives the first guard rod 25 to move up in one of the sealing rings 212. The first guard rod 25 and the first protective cylinder 24 protect the surface of the first screw rod 23 to prevent water and impurities from sticking to the first screw rod 23.

[0028] When the utility model is in use, the fixed cylinder 1 is placed in the pipeline through the handle 218, and the rotating rod 27 is rotated. The rotating rod 27 rotates through the first bevel gear 21, the second bevel gear 22 and the first screw rod 23 to drive the first protective rod 25 to move up in one of the sealing rings 212. The first protective rod 25 and the first protective cylinder 24 protect the surface of the first screw rod 23 to prevent water and impurities from sticking to the first screw rod 23. The first protective rod 25 moves up to drive the support block 26 to contact the inner wall of the pipeline, so that the fixed cylinder 1 is fixed in the pipeline. The first protective rod 25 and the first protective cylinder 24 are used to protect the surface of the first screw rod 23, and the first protective rod 25 moves up to drive the support block 26 to contact the inner wall of the pipeline, so that the fixed cylinder 1 is fixed in the pipeline.

The second protective tube 28 and the second protective rod 29 protect the second screw rod 211 to prevent water and impurities from sticking to the second screw rod 211. The anti-leakage detector 210 is manually turned on and performs anti-leakage detection on the pipeline. When leakage occurs in the pipeline, the anti-leakage detector 210 sounds an alarm to enable the detection personnel to carry out pipeline enclosure protection.

[0029] It should be noted that the anti-leakage detector 210, magnetic block 214 and magnetic ring 213 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the anti-leakage detector 210 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
