Description

Technical Field

[0001] The utility model relates to the technical field of underground pipeline repair, in particular to a trenchless underground pipeline repair device. Background Art

[0002] Underground pipelines are pipes laid underground for transporting liquids, gases or loose solids. After long-term use, underground pipelines are prone to cracks or gaps, which will affect their normal use.

[0003] For example, the utility model patent with application number: 202220593608.X discloses a trenchless underground pipeline repair device, including a remote control vehicle, a liquid storage tank is provided on the upper surface of the remote control vehicle, a pump body is inserted inside the liquid storage tank, the discharge end of the pump body is connected to the air guide cover through a conduit, the groove position on the lower surface of the remote control vehicle is fixedly connected to the support end of the electric push rod, and the transmission output end of the electric push rod is connected to the leveling roller through the wheel frame. After the remote control vehicle moves to the position corresponding to the ground detection point, the pump body is started by the controller, and the repair liquid inside the liquid storage tank is dripped to the damaged part at the bottom end of the pipeline through the air guide cover under the pressure of the pump body, and then the electric push rod drives the leveling roller to fit to the bottom end of the inner wall of the pipeline, the electric heating box is powered on for heating, and the remote control vehicle is controlled to reciprocate, and the leveling roller performs leveling treatment on the repair liquid, and the heat generated by the electric heating box is sprayed out through the air guide cover to dry the repair position, thereby improving the use effect.

[0004] When the device in the above patent is in use, although it can repair the damaged part of the pipe by using a repair fluid and level and heat it after the repair, it lacks the function of adjusting the angle of the deflector. Since the pipe is circular and buried underground, the damaged part of the pipe is full of uncertainty. When the damaged part of the pipe is located above or on both sides of the pipe, the deflector that cannot adjust the angle cannot guide the repair fluid to the damaged part of the pipe, and thus cannot repair the pipe, reducing the practicality of the device.

A control component and an adjustment component are arranged on the remote control car 1, and when the telescopic end of the electric push rod 2 12 is not extended, the height of the scraper 16 is higher than the air guide cover 7 and the heating roller 13.

[0030] The cleaning assembly includes a plurality of telescopic rods 15, and the telescopic ends of the plurality of telescopic rods 15 are fixedly connected with scrapers 16, and receiving plates 17 are fixedly connected on both sides of the scrapers 16. Through the setting of the receiving plates 17, when the scrapers 16 are used to clean the top of the inner wall of the pipe, the sundries and stains dropped during cleaning can be collected to prevent the sundries and stains from falling directly onto the remote control car 1 and making it dirty. The outer surfaces of the plurality of telescopic rods 15 are sleeved with springs 18. Through the setting of the springs 18, when the tube plate is used to clean the inner wall of the pipe, the scrapers 16 can be more closely abutted against the inner wall of the pipe.

[0031] The hose 6 movably passes through the connecting plate 1 11 and the connecting plate 2 25. A spring 2 19 is provided at the top of the connecting plate 25 and on the outer surface of the hose 6. The heating roller 13 is provided at the top of the connecting plate 25.

[0034] Working principle: During operation, after adding a proper amount of repair liquid to the liquid storage tank 3, the remote control car 1 is controlled to move inside the pipeline, and the inner wall of the pipeline is observed through the camera 2 and the illuminator 22. When the remote control car 1 moves, it is found that the inner wall of the pipeline has a damaged part that needs to be repaired, and the part to be repaired is not at the bottom of the inner wall of the pipeline, the wireless transmitter adapted to the wireless receiver 21 transmits the instruction to the controller 20, and the motor 8 is started by the controller 20 to drive the rotating plate 9, the electric push rod 10, the connecting plate 11, the electric push rod 21, the hose 6, the heating roller 13 and the scraper 16 to rotate synchronously until the scraper 16 is rotated to a suitable angle, and then the electric push rod 10 is started by the controller 20, so that the telescopic end drives the scraper 16 to move, and the position of the scraper 16 can be adjusted, that is, in the process of the movement of the remote control car 1 and the scraper 16, the scraper 16 cleans the surface of the damaged part of the pipeline and removes the attached debris and stains;

[0035] After cleaning the damaged part of the pipeline, the electric push rod 12 can be started through the controller 20, so that its telescopic end drives the heating roller 13, the hose 6 and the guide cover 7 to move upward synchronously until the height of the guide cover 7 and the heating roller 13 is higher than the height of the scraper 16, and the position and angle of the guide cover 7 and the heating roller 13 can be adjusted respectively. After adjusting them to the appropriate position, the delivery pump 4 is started through the controller 20 to deliver the repair liquid inside the liquid storage tank 3 to the guide cover 7 through the hose 6 and spray it to the part of the inner wall of the pipeline to be repaired, and then the heating roller 13 heats and levels the repair liquid added to the damaged part of the inner wall of the pipeline to increase the solidification speed of the repair liquid.
