It includes main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they serve as drainage, they should be counted as drainage pipes.

[0003] At present, water supply and drainage pipes are often needed during construction. When enterprises produce and process water supply and drainage pipes, they will use intelligent detection devices to inspect the dimensions of the water supply and drainage pipes to determine whether the product meets the standards. In actual use, although the existing intelligent detection devices can realize basic dimension detection functions, they are inconvenient for the staff due to their complex structures and cumbersome operation procedures. At present, the detection devices on the market can mainly detect the outer diameter of the pipe, but the detection of the inner diameter of the pipe has not been optimized, or the detection method is cumbersome. In view of the above problems, a pipe diameter detection device for water supply and drainage pipes for construction projects is proposed, which can detect the inner and outer diameters of the pipe at the same time and can be clamped and placed.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The pipe diameter detection device for water supply and drainage pipes for construction projects, through the cooperation of the movable vertical rod, the first horizontal rod, the first vertical plate, the connecting rod, the grip rod, the spring, the ruler rod, the scale pointer, the scale line, the second horizontal rod, the building water supply and drainage pipe and the second vertical plate, by pressing the grip rod downward, the device and the building water supply and drainage pipe are squeezed, so that the movable vertical rod slides along the second horizontal rod, so that the movable vertical rod compresses the spring until the bottom of the first horizontal rod is in contact with the outer wall of the building water supply and drainage pipe. At this time, the spacing between the movable vertical rod and the second vertical plate is the outer diameter of the building water supply and drainage pipe, and then by observing the scale position on the scale line where the scale pointer points, the outer diameter of the pipe diameter of the building water supply and drainage pipe is obtained, so that the outer diameter of the pipe of the building water supply and drainage pipe can be quickly measured and detected, which is convenient for the staff to measure and detect the outer diameter of the pipe.

[0013] 2. The pipe diameter detection device for water supply and drainage in the construction project uses the first and second inner diameter detection cross bars in the inner diameter detection mechanism to press the second inner diameter detection cross bar to the required position, and then according to the position of the pipeline, after the two cross bars are extended into the inner wall of the pipeline, the second inner diameter detection cross bar is released, and the rebound of the second telescopic spring will push the second inner diameter detection cross bar to the original position. During the pushing process, the cross bar will rebound and support the inner wall of the upper end of the pipeline. At this time, the position of the inner diameter ruler pointed by the inner diameter pointer blade can be observed to read the current inner wall diameter of the pipeline. This setting effectively solves the problem that the inner diameter of the pipeline is difficult to measure or the measurement deviation is large.

[0014] 3. The pipe diameter detection device for water supply and drainage in construction projects can be placed on the pipe when not in use temporarily through the setting of the caliper fixing device. Hold the handle, aim the crank arm at the pipe, and push it onto the pipe. At this time, the pulley on the crank arm rotates to open the crank arm, and the third telescopic spring is stretched until it is against the pipe and then released. At this time, the rebound force of the third telescopic spring will pull the crank arm inward, which can ensure that the pipe diameter detection device is stably stuck on the pipe. If it is on a vertical pipe, the pipe diameter detection device will droop naturally, and the support base will support the pipe at this time, effectively solving the problem that the device may not be held in the hand at the detection site, or the device may be lost due to random placement.
