[0024] Example:

[0025] See also Figure 1-3 The present embodiment provides a trenchless repair device for urban underground drainage pipes, comprising a box body 1, a motor 11 embedded on the outer surface of the box body 1, an electric telescopic rod 2 mounted on the rotating shaft of the motor 11, one end of the electric telescopic rod 2 connected to a repair mechanism 3, the repair mechanism 3 is equipped with a grinding plate 32 for grinding the inside of the cracked pipe and a nozzle 34 for spraying waterproof coating, a sprayer 4 is mounted on the top of the box body 1, a side of the sprayer 4 is connected to a spraying pipe 42, the spraying pipe 42 can transport the waterproof coating to the repair mechanism 3 for spraying through the nozzle 34, and the trenchless repair device for urban underground drainage pipes is used. When in use, the repair mechanism 3 is inserted into the pipe through the electric telescopic rod 2 and pushed to the cracked part of the pipe. At the same time, the electric telescopic rod 2 is driven by the motor to rotate so that the grinding plate 32 on the repair mechanism 3 grinds the inner wall of the cracked part of the pipe. At this time, the nozzle 34 is driven by the electric telescopic rod 2 again to be located at the cracked part of the pipe. At the same time, the sprayer 4 delivers waterproof coating to the nozzle 34 through the spraying pipe 42, and the nozzle 34 rotates with the rotation of the electric telescopic rod 2, thereby performing rotational spraying on a circle inside the cracked part of the pipe, completing the repair of the cracked part of the pipe. There is no need to excavate the road surface at the cracked part of the pipe, thereby reducing the repair cost and avoiding traffic congestion.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, one end of the electric telescopic rod 2 is connected to a connecting block 21, and two through holes 22 are provided on the connecting block 21. The inner side of the connecting seat 12 is rotatably connected to a rotating rod. The through hole 22 on the connecting block 21 is sleeved on the outer ring surface of the rotating rod. A screw passes through the outer side surface of the connecting seat 12 and passes through another through hole on the connecting block 21 and is threadedly connected to the inner side surface of the connecting seat 12. Therefore, when the screw is installed, the electric telescopic rod 2 can be rotated to facilitate insertion into the pipe. After the screw is installed, the motor 11 can drive the electric telescopic rod 2 to rotate.

The outer sides of the grinding plates 32 move along the inner wall of the pipe. The outer surface of the grinding plates 32 is a layer of sandpaper. Therefore, the grinding plates 32 can grind the cracked inner wall of the pipe, so that the waterproof coating can be firmly adhered to the inner wall of the pipe, achieving a waterproof effect.

[0029] Working principle: When the device for trenchless repair of urban underground drainage pipes is in use, the cracked underground pipe joint is found, and then the repair mechanism 3 is inserted into the pipe and pushed to the cracked part of the pipe. At the same time, the motor is used to drive the electric telescopic rod 2 to rotate so that the grinding plate 32 on the repair mechanism 3 grinds the inner wall of the cracked part of the pipe. At this time, the electric telescopic rod 2 is used to drive the nozzle 34 to the cracked part of the pipe again. The sprayer 4 delivers waterproof paint to the nozzle 34 through the spray pipe 42, and the nozzle 34 rotates with the rotation of the electric telescopic rod 2, thereby performing rotational spraying on a circle inside the cracked pipe, completing the repair of the cracked pipe. There is no need to excavate the road surface at the cracked pipe, thereby reducing the repair cost and avoiding traffic congestion.
