[0030] See also Figure 1-7 The embodiment of the present invention provides an intelligent temporary leak repair robot for pipe network, comprising two main shells 10 and a sub-shell 11 which can be connected to each other, and the connection method thereof can be a thread and a buckle, etc. At least three running frame grooves 13 are provided on both sides of the main shell 10 and the sub-shell 11, and a running frame 12 is rotatably connected in the running frame groove 13. The equipment can be controlled to walk in the pipe by rotating the running frame 12, and the rotation connection part thereof is a torsion spring, and the position of the main shell 10 and the sub-shell 11 of the equipment body can be limited by the torsion spring, so that the main shell 10 and the sub-shell 11 are located in the middle of the pipe, which is convenient for observing the situation in the pipe. The running frame 12 can be retracted into the running frame groove 13 by cooperating with the running frame groove 13, which is convenient for storing and placing the equipment. The main shell 10 also includes a leak repair component and a monitoring component, and the monitoring component includes a monitoring swivel 60 rotating on the main shell 10, and a monitor 61 is installed on the monitoring swivel 60. The monitoring swivel 60 rotates synchronously with the leak repair swivel 20 to monitor the situation in the pipe, and its synchronous rotation facilitates the outside to observe the leak repair situation.

[0031] The leak repair component includes a leak repair swivel 20 rotating on the main housing 10 and a detachably mounted high-pressure gas tank 40. A main gas cavity 25 is also provided in the main housing 10. A first gas valve 26 is provided in the main gas cavity 25. The opening of the high-pressure gas tank 40 is communicated with the main gas cavity 25. An inner swivel 22 is provided in the middle of the leak repair swivel 20. The inner swivel 22 is fixed to the inner ring of the leak repair swivel 20 through a connecting column 21. A movable telescopic group is provided in the connecting column 21. The sealing part thereof does not need to be completely sealed. A slight gas leakage will not affect the expansion of the leak repair elastic spring 24, and will only waste a little high-pressure gas. An annular groove is provided on the main shell 10, and the leak-sealing swivel 20 rotates in the annular groove. The inner swivel 22 is tightly connected to the bottom of the annular groove to form a closed space as a swivel cavity 221. A motor 50 is also fixed in the main shell 10, and a motor gear 51 is installed on the motor 50. The motor gear 51 is meshed with the leak-sealing swivel 20. The rotation of the leak-sealing component and the monitoring component can be controlled by the motor 50, so that it can monitor and repair leaks at any point in the pipeline. In addition, there is a control module on the motor 50, which is used for limited or wireless control of the motor by external equipment.

[0032] A telescopic rod cavity 211 is provided in the connecting column 21, and the telescopic rod cavity 211 runs through the connecting column 21 and the inner rotating ring 22. The main air cavity 25 is communicated with the closed space of the inner rotating ring 22, and is also communicated with the telescopic rod cavity 211. The telescopic group is installed in the telescopic rod cavity 211, and the telescopic group includes a telescopic rod 23. A reset spring 27 is installed between the telescopic rod 23 and the inner wall of the telescopic rod cavity 211. The reset spring 27 is located on the outer peripheral side of the telescopic rod 23. The telescopic rod 23 is hollow. A leak-proof elastic spring 24 is connected to the top of the telescopic rod 23 by a buckle. The leak-proof elastic spring 24 is divided into four parts, and a one-way ball 241 is arranged at the bottom. The materials of the other three parts are all one of rubber and resin, and the elasticity of the middle part of the three parts is less than the elasticity of the other two parts, and the thickness of the middle part is greater than The thickness of both sides is large, and the leak-sealing elastic bullet 24 also has a certain wear resistance, so irregular holes can be prevented from puncturing the leak-sealing elastic bullet 24. When in use, the leak-sealing elastic bullet 24 can be directly installed, and the loading is extremely convenient. Moreover, the high-pressure gas in the high-pressure gas tank 40 cooperates with the elastic leak-sealing elastic bullet 24 to expand both sides of the leak-sealing elastic bullet 24 at the same time and squeeze it into the leaking hole. With the help of the water pressure, the leak can be completely blocked by its own elasticity. On the one hand, a large amount of leakage can be reduced, and on the other hand, the staff can have a longer construction time to avoid urgent construction and mistakes in chaos. Moreover, since the leak-sealing elastic bullet 24 is elastic, no matter it is a large hole or a small hole, or a hole of irregular shape, it can be adaptively adjusted through elasticity to achieve the purpose of temporary leak repair.

[0033] A leak repairing method for an intelligent pipe network temporary leak repairing robot, the method steps are as follows: S1: Put the device into the pipeline, and move it in the pipeline through the walking frame 12. Outsiders use external display equipment to check the situation in the pipeline through the monitoring component; S2: When the device detects a water leak, the first gas valve 26 in the device can be opened through a wire or a wireless module to control the high-pressure gas in the high-pressure gas tank 40 to be filled into the telescopic rod cavity 211 through the main gas cavity 25, so that the telescopic group is extended and the leak-proof elastic spring 24 is sent into the leaking hole; S3: After the leak-sealing elastic bullet 24 enters the hole, the two ends of the leak-sealing elastic bullet 24 are expanded by the high-pressure gas, gradually blocking the hole, and completing the leak-sealing process.

[0034] Working principle: open the walking frame 12 from the walking frame slot 13 and put it into the pipeline. Through external intelligent control, the equipment can be moved in the pipeline. The equipment as a whole has no up and down distinction, so it can be directly controlled to move forward and backward. By rotating the monitoring swivel 60, the monitor 61 can detect the situation in the pipeline. When encountering a leak in a hole in the pipeline, the equipment can be stopped, and the viewing angle of the monitor 61 is slightly tilted to the hole. At this time, the leak-proof elastic spring 24 will be facing the hole, and then the first air valve 26 is started from the outside to open it. At this time, the high-pressure gas in the high-pressure gas tank 40 enters the main air cavity 25, and then passes into the telescopic rod 23, driving the telescopic rod 23 to compress the reset spring 27 and extend it outward, directly piercing the leak-proof elastic spring 24 into the hole. At this time, the telescopic rod 23 will abut against the pipeline On the inner wall, the leak-proof elastic bullet 24 cannot completely penetrate into the hole, and its thicker part is located at the thick wall of the pipe. The telescopic rod 23 is restricted, and the gas will continue to be filled in, pushing open the one-way ball 241 to make the three elastic parts of the leak-proof elastic bullet 24 expand. Among them, the middle part of these three parts is thicker and expands slower, and the two sides expand faster, which will quickly block the leakage port without a long waiting time, effectively preventing a large amount of liquid leakage. Then close the first air valve 26, and the gas in the main air cavity 25 will leak out from the place where it is not completely sealed. Since both sides of the leak-proof elastic bullet 24 are expanded and limited, and the one-way ball 241 can prevent the gas in the leak-proof elastic bullet 24 from leaking out, at this time, the telescopic rod 23 will be separated from the leak-proof elastic bullet 24 and reset under the elastic force of the reset spring 27.

[0035] At this time, the robot can be controlled to move out of the pipeline and repair the pipeline. When the main switch of the pipeline is turned off, the leaking pipeline can be disassembled for replacement or repair. During maintenance, the one-way ball 241 can be pushed open to release the gas in the leak-proof elastic spring 24 for recycling.

[0036] When the gas in the high-pressure gas tank 40 is used up, the main shell 10 and the sub-shell 11 can be separated, the high-pressure gas tank 40 can be rotated to be removed, and replaced with a new high-pressure gas tank 40. When the high-pressure gas tank 40 hits the inner wall of the main shell 10, its switch is pushed open, and the gas will enter the main gas cavity 25 and be restricted and sealed by the first gas valve 26. Embodiment 2

[0037] On the basis of the first embodiment, the main shell 10 and the sub-shell 11 also include an air passage, and the air passage includes a second air passage 34 and a first air passage 31. The second air passage 34 is connected to the main air cavity 25, and the first air passage 31 is located in the sub-shell 11. The high-pressure gas tank 40 can be detachably installed in the main shell 10, and its air vent is connected to the main air cavity 25. A first air valve 26 is also provided in the main air cavity 25. The connecting port between the second air passage 34 and the main air cavity 25 is located between the first air valve 26 and the high-pressure gas tank 40. A second air valve 35 is also provided on the second air passage 34, and the opening and closing of the second air valve 35 can also be controlled by external equipment. A raised ring is provided at one end of the main shell 10 close to the sub-shell 11 for connecting to the sub-shell 11. A ventilation annular groove 36 is provided in the raised ring. The second air passage 34 is connected to the ventilation annular groove 36. A rubber sleeve 30 is fixed on the outer peripheral side, one end of the first air passage 31 is connected to the rubber sleeve 30, a ventilation annular block 33 is also fixed to one end face of the sub-housing 11, and the ventilation annular block 33 cooperates with the ventilation annular groove 36, the other end of the first air passage 31 is connected to the ventilation annular block 33, and a one-way valve 32 is also arranged in the first air passage 31, and the one-way valve 32 is used to achieve the purpose of one-way flow of gas. Through the setting of the rubber sleeve 30, when encountering a very large leakage hole, it is impossible to repair it by general means. By opening the second air valve 35, the high-pressure gas can directly fill the rubber sleeve 30, so that it reaches the maximum expansion, completely blocks the entire pipeline, and restricts the flow of liquid in the pipeline, so as to achieve the purpose of temporary leak repair and effectively avoid large-scale leakage of liquid. When the outside staff turns off the main switch, the pipeline can be replaced.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
