[0016] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] This embodiment provides a trenchless pipeline repair device, as shown in Figures 1 to 3 shown, including: a pipeline 1, a repair device 2, a repair device 3, an oil pressure pump 4, a pressure sensor 5, and a receiver 6; the repair device 2 slides inside the pipeline 1; the repair device 3 is installed on the repair device 2 and is used to repair the cracked part of the pipeline 1; the oil pressure pump 4 is arranged on one side of the inlet of the pipeline 1 and is used to drive the repair device 2 to move inside the pipeline 1; the pressure sensor 5 is arranged on the repair device 3 and is used to detect the pressure condition of the repair device 3 at the crack of the pipeline 1; the receiver 6 is electrically connected to the pressure sensor 5 and is used to receive the feedback signal transmitted by the pressure sensor 5.

[0018] Before carrying out the repair operation, the construction personnel perform inspections through existing technologies and use a pipeline 1 inspection robot to locate and detect the rupture gap of pipeline 1, so as to accurately position during the repair operation.

[0019] Based on the above basic structure, the repair device 3 includes a repair airbag 7, a fiber cloth 8, an air extraction pump 9, an air extraction pipe 10, and a bandage 11. The repair airbag 7 is installed on the repairer 2. The fiber cloth 8 is wrapped around the repair airbag 7. The bandage 11 is fastened to both ends of the fiber cloth 8. One end of the air extraction pipe 10 is connected to the air extraction pump 9, and the other end of the air extraction pipe 10 is connected to the repair airbag 7. The air extraction pump 9 is arranged at the access opening of pipeline 1.

[0020] The fiber cloth 8 is made of glass fiber, which has high tensile strength, small elongation, high elastic modulus, good rigidity, so it absorbs a large amount of impact energy, has good chemical resistance, good adhesion to resin, and is inexpensive. The length of the fiber cloth 8 wrapped around the repair airbag 7 is less than that of the repair airbag 7. The bandage 11 is an elastic bandage 11, and when subjected to a certain impact pressure, the bandage 11 automatically breaks. The air extraction pump 9 pumps air into and out of the repair airbag 7 through the air extraction pipe 10 to realize the inflation and deflation of the repair airbag 7. The pressure sensors 5 are installed at both ends of the fiber cloth 8 and are connected to the repair airbag 7.

[0021] Based on the above basic structure, guide wheels 12 are also installed at both ends of the repairer 2, and the guide wheels 12 are arranged in a triangular shape.

[0022] The guide wheels 12 installed at both ends of the repairer 2 facilitate the transmission of the repairer 2 and the repair device 3 on the repairer 2 along the inner wall of pipeline 1, changing from sliding friction to rolling friction, reducing the frictional resistance, improving the transmission efficiency. At the same time, the guide wheels 12 are in contact with the inner wall of pipeline 1 to avoid friction between the repair device 3 and pipeline 1 and prevent the problem of damage to the repair device 3 during the transmission process.

[0023] Based on the above basic structure, the pressure sensors 5 are arranged at both ends of the repair airbag 7, and the pressure sensors 5 are arranged in a triangular shape on each end of the repair airbag 7.

[0024] There are three pressure sensors 5 at each end of the repair airbag 7, which just press against different positions on the inner wall of pipeline 1, so as to detect and observe the inflation situation of the repair airbag 7 at different positions inside pipeline 1.

[0025] Based on the above basic structure, the repairer 2 includes an inner rubber ring and a housing, and the housing is arranged on the inner rubber ring.

[0026] Based on the above basic structure, the fiber cloth 8 is inflated by the repair airbag 7, and the fiber cloth 8 is in close contact with the inner side wall of pipeline 1.

[0027] Working principle: Construction workers will mix the resin according to the mass ratio for patching the gap. The mixed resin is poured onto the fiber cloth 8 and evenly spread on the fiber cloth 8 so that the resin evenly covers it. The coated fiber cloth 8 is wrapped around the repair airbag 7. At this time, the repair airbag 7 is in a deflated state. Then, the two ends of the fiber cloth 8 are tightened with a bandage 11 for shaping and limiting. Within 10 to 15 minutes after the resin is mixed, the repair airbag 7 is dragged into the pipeline 1. The hydraulic pump 4 is used to transport the repair device 2 and the repair airbag 7 to the rupture gap. The repair airbag 7 is inflated to break the bandage 11 on the fiber cloth 8 and release the restriction of the bandage 11 on the fiber cloth 8. The fiber cloth 8 bulges with the repair airbag 7 and fits against the inner wall of the ruptured pipeline 1. The pressure sensor 5 on the repair airbag 7 sends a signal to the part that touches the inner wall of the pipeline 1 and transmits it to the receiver 6. Construction workers can judge whether the fiber cloth 8 fits against the inner wall of the pipeline 1. If the fit degree is not enough, the air pressure of the repair airbag 7 is appropriately increased by the air extraction pump 9 to expand the tightness of the repair airbag 7 against the pipeline 1. A desiccant is used for drying and curing. After a period of time, the repair airbag 7 is deflated, and the repair airbag 7 and the repair device 2 are dragged out along the original path, thus completing the repair work.

[0028] During the repair operation, the situation and problems of the repair can be understood in a timely manner, the repair efficiency and quality can be improved, manual trenchless repair and non-entry operation into the pipeline 1 can be realized, the pipeline 1 repair technology can be further improved, and the efficiency of human-machine interaction, real-time observation and detection in a special environment can be improved.

[0029] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
