[0031] The rubber sealing clamp 14 on the other detection sealing clamp 4 on the other side of the bottom plate 1 is embedded with a gas pressure pipe 15 penetrating to the outside of one side of the detection sealing clamp 4, the gas pressure pipe 15 is a hard pipe made of stainless steel, one end of the gas pressure pipe 15 is in sealed communication with the internal cavity of the rubber sealing clamp 14, and the other end is integrally formed in a sealed manner; the detection pressure gauge 7 is installed on the upper end of the gas pressure pipe 15 through screw threads, and is used for displaying the change of the gas pressure in the water supply and drainage pipe in real time, so as to detect the quality of the water supply and drainage pipe.

[0032] The adjusting cylinder 16 is symmetrically installed in the inner cavity of the bottom portion of the detection sealing clamp 4, the adjusting cylinder 16 is an electric push rod type structure, the cylinder body is fixed on one side of the end portion of the driving slide plate 3 through bolts, the top end of the push rod is fixedly connected with the bottom portion of the detection sealing clamp 4, and the detection sealing clamp 4 is driven to move up and down through the extension and retraction of the push rod.

[0034] Specifically, in use, the water supply and drainage pipe is positioned and adjusted as follows: the water supply and drainage pipe is placed on the base plate 1, the distance between the two drive sliding plates 3 is adjusted according to the length of the water supply and drainage pipe, the drive sliding plate 3 is pushed to slide in the transverse sliding groove 2 by the air cylinder 8, the distance between the two drive sliding plates 3 is changed, and the positioning in the length direction is completed; at the same time, the telescopic air cylinder 17 drives the lifting placement plate 5 to lift, so that the water supply and drainage pipe is at a proper height, and the preliminary positioning in the height direction is completed. In addition, for the water supply and drainage pipes with different diameters, the detection sealing clamp plate 4 is driven to lift by the adjusting air cylinder 16, so that the rubber sealing clamp plate 14 on the detection sealing clamp plate 4 can be accurately aligned with the two ends of the water supply and drainage pipe, and the sealing preparation is completed. In this process, the strip-shaped limiting sliding blocks 9 on the two sides of the drive sliding plate 3 slide in the limiting sliding groove 10, so that the stability and accuracy of the movement of the drive sliding plate 3 are ensured, and the positioning accuracy is prevented from being affected by deviation.

[0036] Air pressure detection process: after the sealing is completed, the air pump 12 extracts gas from the gas supply tank 11, the gas is delivered to the air pump 12 through the air pipe, and the gas supply hose 13 connected to the output end of the air pump 12 injects the gas into the sealed water supply and drainage pipe. During the gas supply process, the pressure relief valve plays a protection role, and when the gas supply pressure exceeds the set value, the pressure relief valve is automatically opened to prevent the water supply and drainage pipe or the detection device from being damaged due to excessively high air pressure. At the same time, the change of the air pressure in the water supply and drainage pipe is conducted to the detection pressure gauge 7 through the air pressure pipe 15 at the center position of the rubber sealing clamp plate 14 on the detection sealing clamp plate 4 on the other side of the base plate 1, and the detection personnel can observe the change of the air pressure in the water supply and drainage pipe in real time through the detection pressure gauge 7, and determine whether the water supply and drainage pipe has quality problems such as leakage according to the change of the air pressure. For example, if the air pressure obviously decreases within a specified time, it indicates that the water supply and drainage pipe may have problems such as damage or poor sealing; if the air pressure remains stable, it indicates that the water supply and drainage pipe has good sealing performance.
