[0027] Compared with the prior art, the advantages and positive effects of the present invention are:

[0028] 1. In the present invention, when treating water pollution in urban rivers, the usual sewage treatment process includes the steps of water intake, aeration, sedimentation and drainage. The sedimentation step is generally carried out in a sedimentation tank, mainly to achieve mud and water separation, and the separated water and mud are recycled and reused. In the process of diverting most of the daily drainage to the entire underground waterway, the water flow in the main river will be too large, which may easily cause the entire water flow to flow backwards. At this time, the water in the entire underground water pipe is prevented from flowing backwards by using a regulating device.

[0029] 2. In the present invention, by setting an adjusting device, when the entire connecting frame and the carrying plate are operated and used, in order to avoid the backflow of sewage, the connecting rod sliding through the carrying plate is fixed and limited with the connecting plate, and then the extrusion block on the connecting plate is plugged and limited with the through hole opened on the carrying plate, which effectively avoids the backflow of sewage from the through hole, and the drainage ring at the bottom of the carrying plate can effectively avoid the upward guidance of sewage.

When the connecting column on the entire connecting plate is slid and limited, in order to avoid the rotation of the position of the entire connecting column, the positioning plate on the connecting column and the positioning groove are relatively slid and fixed, and the inlaid ring on the through hole can effectively abut and fix the top frame.

[0030] 3. In the present invention, by setting an auxiliary device, when the entire river channel body is used, in order to avoid a large amount of pollutants floating inside the river channel, the mobile frame on the connecting frame is slid, thereby driving the driving shaft and the connecting rope on the entire mobile frame to slide along the mobile frame through the moving column, and the airbag on the connecting rope can effectively prevent the auxiliary hook on the connecting rope from sinking, and the counterweight ball in the airbag can prevent the airbag from excessively floating on the surface of the river channel. When the auxiliary hook is used to clean the floating dirt on the river channel body, the auxiliary hook is used to clean it, and then the scraper rotating on the auxiliary hook is used for auxiliary cleaning, and then the connecting hook on the auxiliary hook is used for better operation and use to avoid the detachment of the floating dirt. After the driving shaft on the moving frame is rotated, in order to avoid the loosening of the connecting rope on the driving shaft, it is fixed by the connecting plate on the moving frame, and then the moving rod on the connecting plate is used, so that the tension generated by the second spring on the moving rod squeezes and limits the position of the entire moving rod, so that the moving rod and the limiting hole opened on the driving shaft are plugged and fixed.

[0031] 4. In the present invention, by setting a protective device, when sewage is discharged by using the connecting pipe on the main body of the river channel, in order to prevent excessive debris from flowing into the river channel, protection is provided by a protective frame. In order to fix and limit the protective frame, the protective frame is rotated by a rotating frame, and then the connecting block on the bottom surface of the protective frame is clamped with the rotating block on the positioning column, which is convenient for opening and closing the protective frame, thereby facilitating the protection and limiting of the entire connecting pipe. When the position of the rotating frame is rotated, the torsional force generated by the coil spring on the positioning column can conveniently squeeze and limit the position of the rotating frame.

[0054] Example 2, based on Example 1,

In the process of diverting most of the daily drainage to the entire underground waterway, there will be too much water flow in the main river, which may easily cause the entire water flow to flow backwards. At this time, the regulating device 4 is used to prevent the water in the entire underground water pipe 3 from flowing backwards.

[0056] When the entire connecting frame 8 and the carrying plate 42 are operated and used, in order to prevent the backflow of sewage, the connecting rod sliding through the carrying plate 42 is fixed and limited with the connecting plate 44, and then the extrusion block 46 on the connecting plate 44 is plugged and limited with the through hole 43 opened on the carrying plate 42, which effectively prevents the sewage from flowing back from the through hole 43, and the drainage ring 49 at the bottom of the carrying plate 42 can effectively prevent the sewage from being drawn up. In the process of plugging and sealing the extrusion block 46 on the connecting plate 44 with the through hole 43, in order to limit the flow of sewage flowing down from the connecting plate 41, By sliding the fixed tube 471 and the sliding tube 474 on the extrusion block 46, the tension generated by the first spring 472 is used to move the position of the top frame 473 on the sliding tube 474, so that the top frame 473 and the through hole 43 are abutted and limited. When the connecting column 45 on the entire connecting plate 44 is slid and limited, in order to prevent the entire connecting column 45 from rotating, the positioning plate 481 and the positioning groove 482 on the connecting column 45 are relatively slid and fixed, and the embedded ring 483 on the through hole 43 can effectively abut and fix the top frame 473.

[0057] When the entire channel body 1 is used again, in order to avoid a large amount of pollutants floating inside the channel, the mobile frame 602 on the connecting frame 601 slides, thereby driving the driving shaft 603 and the connecting rope 604 on the entire mobile frame 602 to slide along the mobile frame 602 through the moving column 610, and the airbag 605 on the connecting rope 604 can effectively prevent the auxiliary hook 606 on the connecting rope 604 from sinking, and the counterweight ball 609 in the airbag 605 can prevent the airbag 605 from excessively floating on the surface of the channel. When the auxiliary hook 606 is used to clean the floating dirt on the channel body 1, the auxiliary hook 606 is used to clean it, and then the auxiliary hook 606 is used to clean it. The rotating scraper 6072 on the barb 606 is used for auxiliary cleaning, and then the connecting hook 6073 on the auxiliary barb 606 is used for better operation to avoid the detachment of floating dirt. After the driving shaft 603 on the moving frame 612 is rotated, in order to avoid the loosening of the connecting rope 604 on the driving shaft 603, it is fixed by the connecting plate 6111 on the moving frame 612, and then the moving rod 6112 on the connecting plate 6111 is used to allow the tension generated by the second spring 6113 on the moving rod 6112 to squeeze and limit the position of the entire moving rod 6112, so that the moving rod 6112 and the limiting hole 6114 opened on the driving shaft 603 are plugged and fixed.

[0058] When sewage is discharged by the connecting pipe 7 on the river channel body 1, in order to prevent excessive debris from flowing into the river channel, protection is provided by the protective frame 52. In order to fix and limit the protective frame 52, the protective frame 52 is rotated by the rotating frame 51, and then the connecting block 55 on the bottom surface of the protective frame 52 is clamped with the rotating block 53 on the positioning column 54, so as to facilitate the opening and closing of the protective frame 52, thereby facilitating the protection and limiting of the entire connecting pipe 7. When the position of the rotating frame 51 is rotated, the torsional force generated by the coil spring 57 on the positioning column 54 can conveniently squeeze and limit the position of the rotating frame 51.
