Title:
INDOOR CONCEALED PIPE LEAKAGE DETECTION DEVICE FOR RENOVATING OLD RESIDENTIAL AREA
Document Type and Number:
WIPO Patent Application WO/2022/120720
Kind Code:
A1
Abstract:
Disclosed is an indoor concealed pipe leakage detection device for renovating an old residential area, comprising a base, a clamping mechanism, clamping plates, a fixing seat, a rotating shaft, a sliding plate, a sliding groove, a fixing block, a compression spring, a gas injection mechanism, a gas injection groove, a pressure relief mechanism, a pressure groove, an extrusion spring, a gas discharge groove, a gas inlet groove, a pressure block, an extrusion mechanism, a push block, a slot and a protrusion. The beneficial effects of the present invention are as follows: when the push block is rotated, the push block will slide along the outer side of the base under the action of a thread, so that two clamping plates are lifted up at one end, thereby clamping and fixing a concealed pipe; meanwhile, when the push block is moved, the clamping plates and the sliding plate will be pulled to slide inside the sliding groove, facilitating a collision between the base and the concealed pipe, so that the sealing performance is better; and the base is connected to an external air pump by means of a connecting sleeve, so that gas can be pumped into the concealed pipe by means of the gas injection groove, and is discharged by means of the pressure relief mechanism, so as to determine and detect the air sealability inside the concealed pipe, and prevent harm due to internal gas leakage caused by damage of the concealed pipe.
