Most of the existing detection methods are to detect on the ground through a detector. Most of the existing detectors are ultrasonic detectors, which detect whether the drainage network leaks through ultrasonic waves. Since the drainage network is buried underground, using ultrasonic detection is easily affected by the underground environment, resulting in errors.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a drainage pipe network leakage detection device, including a driving frame 1, a first plugging plate 2 is fixed on one side of the driving frame 1, a second plugging plate 3 is installed on one side of the first plugging plate 2, a connecting pipe 7 is installed between the first plugging plate 2 and the second plugging plate 3, a fixing structure is installed in the connecting pipe 7, the fixing structure corresponds to the first plugging plate 2 and the second plugging plate 3, elastic plugging rings 11 are installed on the circumferences of the first plugging plate 2 and the second plugging plate 3, a first air pipe 5 and a second air pipe 6 are fixed on the driving frame 1, the first air pipe 5 corresponds to the first plugging plate 2, and a plurality of pressure sensors 15 are fixed on the second plugging plate 3.

[0022] In this embodiment, a plurality of first telescopic rods 4 are fixed on the circumference of the driving frame 1, and electric wheels 13 are fixed at the ends of the first telescopic rods 4.

[0023] Specifically, the driving frame 1 can be driven to move by the electric wheels 13, so that the device moves in the drainage pipe, and the position of the electric wheels 13 can be adjusted by the first telescopic rods 4, so as to ensure that the electric wheels 13 can be in contact with the inner wall of the drainage pipe network, so as to facilitate the movement of the device in the drainage pipe network.

[0024] Cavities 8 are opened in both the first plugging plate 2 and the second plugging plate 3, the cavities 8 are communicated with the connecting pipe 7, one end of the first air pipe 5 is communicated with the cavity 8, one end of the second air pipe 6 is located on the side of the first plugging plate 2 close to the second plugging plate 3, a plurality of pressure sensors 15 are fixed on the side of the second plugging plate 3 close to the first plugging plate 2, the fixing structure includes a fixing rod 9, fixing plates 10 are fixed at both ends of the fixing rod 9, the fixing plates 10 are located in the cavity 8, the fixing plates 10 are fixedly connected with the inner wall of the cavity 8, a plurality of second telescopic rods 14 are fixed on the circumferences of the first plugging plate 2 and the second plugging plate 3, the ends of the second telescopic rods 14 are fixedly connected with the elastic plugging rings 11, the elastic plugging rings 11 correspond to the cavities 8, and elastic plates 12 are installed between the two sides of the elastic plugging rings 11 and the inner wall of the cavity 8. The elastic plugging rings 11, the cavities 8, the elastic plates 12 and the connecting pipe 7 form a sealing structure.

[0025] Specifically, when it is necessary to detect a certain part of the drainage pipe network, the first air pipe 5 is used to inflate the cavity 8, so that the elastic plate 12 and the elastic plug ring 11 bulge under the action of air pressure until the elastic plug ring 11 contacts the inner wall of the drainage pipe network. At this time, a sealing structure will be formed between the first plug plate 2, the second plug plate 3 and the drainage pipe network.

At this time, the air pressure is detected by the pressure sensor 15, and it can be judged whether the drainage pipe network leaks.
