[0038] A first sealing gasket 143 is provided at the connection position between the internal thread hole and the hole 142, and a second sealing gasket 144 is fixedly provided at the end of the cover body 141 away from the hole 142;
[0039] Among them, the sealing cover 140 is passed through the channel 142 on the guide column 110, and the sealing cover 140 is threadedly locked on the tubular joint 135 on the outside of the circular plugging plate 131 through the internal threaded hole thereon; one of the circular plugging plates 131 is connected to a water inlet pipe; wherein, the water inlet pipe structure is not shown in the various drawings.
[0040] In this embodiment, the annular plate 121 is circumferentially provided with a plurality of fixing holes, in which locking bolts 123 are installed; the locking bolts 123 are connected circumferentially on the annular plate 121 to fix the annular plate 121 and the supporting disc 122 to the inner wall of the drain pipe.

[0043] The method of using the concrete drain pipe detection device provided by the embodiment of the utility model is as follows:
[0044] 1. Figure 7 As shown, first move the support frame into the drain pipe 200, install the locking bolts 123 in the circumferential fixing holes of the annular plate 121, and tighten the locking bolts 123 to fix the support frame to the inner wall of the drain pipe 200;
