DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-4 A pipeline network leak monitoring and early warning system, comprising a mounting frame 1, the mounting frame 1 is provided with a positioning assembly, and the mounting frame 1 is provided with a walking assembly;

[0023] The walking assembly comprises two outer tubes 2 fixedly connected with the mounting frame 1, the outer tubes 2 are fixed on the two sides of the mounting frame 1, the outer tubes 2 are slidably connected with inner tubes 3, and the inner tubes 3 are provided with external threads, one end of the outer tube 2 away from the mounting frame 1 is rotatably connected with a threaded sleeve 4 matched with the external threads, one end of the inner tube 3 away from the outer tube 2 is fixedly connected with a connecting plate 5, the inner wall of the connecting plate 5 is rotatably connected with a plurality of driven wheels 6, and the connecting plate 5 is provided with a drive wheel assembly;

[0024] It should be noted that the present scheme is compatible with the monitoring system fixed on the pipeline, and is used for remotely starting further investigation of the leak position after the monitoring system finds that there is a leak in the pipeline network route;

[0025] When installing and laying, the user sets the mounting frame 1 between two adjacent pipelines, then rotates the threaded sleeve 4 to drive the inner tube 3 to move away from the outer tube 2, until the drive wheel 11 assembly abuts against the sidewall of the pipeline of the pipeline network, and after the monitoring system finds that there is a leak in the pipeline network, the walking assembly and the positioning assembly are controlled to run, the walking assembly is used to drive the positioning assembly to move along the pipeline, after the positioning assembly senses the leak position, the position information is fed back, so that the leak can be quickly positioned, manual investigation of the leak position along the pipeline network route on the ground is not needed, the detection accuracy of the early warning system on the leak is improved, and the maintenance personnel can directly excavate or enter the underground to repair the work, so that the time of the leak is reduced, and the resource loss is reduced.

[0026] Further, the driving wheel assembly comprises a cross frame 7 fixedly connected with the connecting plate 5, a supporting rod 8 is slidably connected with the cross frame 7, one end of the supporting rod 8 away from the cross frame 7 is rotatably connected with a connecting rod 9, a compression spring 10 is sleeved on the supporting rod 8, and the two ends of the compression spring 10 are respectively arranged in abutment with the cross frame 7 and the connecting rod 9, a driving wheel 11 is rotatably connected with the connecting rod 9, and a driving motor 12 is fixedly connected with the connecting rod 9, and the driving motor 12 is in transmission connection with the driving wheel 11 through a belt;

[0027] In this design, the supporting rod 8 and the connecting rod 9 are rotatably connected in the middle, and the driving wheel 11 is arranged at the two ends of the connecting rod 9. When the driving wheel 11 abuts against the outer wall of the pipeline, the elastic potential energy of the compression spring 10 is converted into the pressure of the driving wheel 11 on the outer wall of the pipeline, so that the friction between the driving wheel 11 and the outer wall of the pipeline can meet the purpose of driving the positioning assembly to move along the pipeline. The pipeline often has valves and pipe clamps. When the driving wheel 11 assembly moves to the position of the pipe clamp or the valve, the outer wall of the pipe clamp and the valve can drive the driving wheel 11 to move towards the cross frame 7. At this time, the driving wheel 11 located in the front drives the connecting rod 9 to rotate and makes the supporting rod 8 slide towards the cross frame 7, and the compression spring 10 is further compressed. Then, the rear driving force drives the connecting rod 9 to rotate to the posture parallel to the cross frame 7. After passing through the valve or the pipe clamp, the compression spring 10 drives the driving wheel 11 to return to the state of abutting against the outer wall of the pipeline. This design can effectively ensure the passability of the walking assembly when moving along the pipeline, improve the effective range covered by the positioning assembly, and reduce the equipment cost of the leak point early warning system.

[0028] Further, the inner tube 3 is also threadedly connected with a rotating sleeve 13, the rotating sleeve 13 is rotatably connected with a snap ring 14, the snap ring 14 is fixedly connected with an adjusting frame 15, the connecting plate 5 is made of elastic metal material, and the adjusting frame 15 is arranged in abutment with the connecting plate 5.

[0029] In this design, the rotating sleeve 13 can drive the adjusting frame 15 to move, so that the adjusting frame 15 drives the connecting plate 5 to bend to different radii, thereby ensuring that the driven wheel 6 can abut against the outer walls of pipelines with different outer diameters. Especially in the environment of pipe network with different outer diameters on both sides, in addition, when the walking assembly moves, the elasticity of the connecting plate 5 can be utilized, so that the driven wheel 6 can deform the connecting plate 5 when encountering a valve or a pipe clamp, thereby ensuring the passability of the walking assembly.

[0030] Further, the positioning assembly comprises a pipeline leak detector 16 fixedly connected with the mounting frame 1, the pipeline leak detector 16 is provided with a positioning chip and a wireless communication module, the outer tube 2 is provided with a storage battery 17, and the storage battery 17 is electrically connected with the pipeline leak detector 16 and the walking assembly.

[0031] In this design, the pipeline leak detector 16 is a device in the prior art that accepts sound waves and reduces noise (eliminates water flow noise in the pipeline), and then identifies whether there is abnormal noise through AI or manual listening, and determines the location of the leak point. The positioning chip is a device for positioning the location of the pipeline leak detector 16. In the case of a wireless communication module, it can carry AI noise recognition positioning, manual listening recognition to find the leak point, and positioning. The battery 17 is used to power the pipeline leak detector 16 and the driving motor 12. In addition, with this positioning assembly, multiple pipelines in the pipe network system can be covered. When laying out the device, the device is preferably set between the main pipeline without bends and branches and the pipeline with a long parallel section.

[0032] Further, the belt is a toothed belt, and the connecting rod 9 is provided with an auxiliary wheel 18, and the auxiliary wheel 18 is arranged in abutment with the belt;

[0033] The driving motor 12 output end and the driving wheel 11 axle are provided with belt pulleys, which ensures that the driving motor 12 can drive the driving wheel 11 to rotate, and the auxiliary wheel 18 is used to make the belt closely fit the belt pulley connected with the driving motor 12, ensuring the transmission effect.

Any person skilled in the art within the technical scope disclosed by the present application can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
