[0043] A regulating assembly 5 is arranged on one side of the pollution cleaning machine body 11, the regulating assembly 5 further adjusts the running power of the driving motor 13 through the adjusting assembly 3 according to the accumulation degree of floating objects detected by the reciprocating assembly 4, and adjusts the reciprocating moving rate of the reciprocating assembly 4 according to the flow rate of water flow;

[0044] An intermittent assembly 6 is arranged on one side of the regulating assembly 5, the intermittent assembly 6 adjusts the time interval between two adjacent working times of the reciprocating assembly 4 according to the flow rate of water flow.

[0045] In the process of cleaning the floating objects on the river surface by the rotary cleaner body 11, the floating objects and other impurities on the water surface are intercepted by the grid 14, the movement of the rake chain is driven by the driving motor 13, and then the plurality of tooth rakes 12 are driven to rotate with the rake chain, the intercepted floating objects and other impurities are lifted out of the water surface, and the tooth rakes 12 move to the upper side of the discharge port and are automatically turned over through the curved rail, so that the floating objects and other pollutants are unloaded into the cleaning tank, and the river water flows out through the gap of the grid 14.

[0046] The detection assembly 2 includes two tooth rod members 21 symmetrically arranged on the front and rear sides of the cleaner body 11, the lower ends of the two tooth rod members 21 are fixedly provided with first floats 22, the first floats 22 float on the river surface, the outer sides of the two tooth rod members 21 are slidably provided with a plurality of guide members 23 fixedly provided on the cleaner body 11, the guide members 23 can guide and limit the up-down movement of the tooth rod members 21, and the tooth gears 24 are engagedly connected between the two tooth rod members 21.

[0047] The telescopic end of the first telescopic piece 25 is fixedly provided with a mounting shell 26, the gear 24 is fixedly provided with a pressure rod piece 27 on the side close to the mounting shell 26, a rotary knob type rheostat 210 is fixedly provided in the mounting shell 26, the rotary knob type rheostat 210 is electrically connected with the driving motor 13, one end of the pressure rod piece 27 is fixedly provided with a rotary knob contact piece of the rotary knob type rheostat 210, the pressure rod piece 27 is coaxially arranged with the fixed end of the rotary knob contact piece of the rotary knob type rheostat 210, and is coaxial with the gear 24, the first switch 28 and the second switch 29 are respectively arranged on the inner side of the mounting shell 26, the telescopic end of the first telescopic piece 25 is fixedly provided with a protective shell 211 away from the mounting shell 26, and the protective shell 211 can protect the components on the inner side.

[0048] When the river surface floating objects are cleaned by the cleaner body 11, the river surface floating objects are intercepted by the grid 14, with the accumulation of the floating objects in front of the grid 14, the water level difference between the front and back of the grid 14 gradually increases, the height difference between the two first floating bodies 22 gradually increases, the gear 24 is deflected through the change of the height position of the two tooth rod pieces 21, thereby driving the pressure rod piece 27 to rotate towards the second switch 29, when the pressure rod piece 27 presses the second switch 29, the water level difference between the front and back of the grid 14 reaches a threshold value, at this time, the cleaner body 11 is controlled to work, the driving motor 13 is controlled to drive the rake tooth chain and the plurality of tooth rakes 12 to rotate, and the floating objects and impurities intercepted in front of the grid 14 are lifted and cleaned; the rotation of the pressure rod piece 27 can simultaneously drive the synchronous rotation of the rotary knob contact piece of the rotary knob type rheostat 210, so that the resistance value of the rotary knob type rheostat 210 connected in the circuit is reduced, thereby the driving motor 13 has relatively large operating power, the pressure rod piece 27 has relatively large deflection angle, which indicates that the water level difference between the front and back of the grid 14 is relatively large, and the accumulation degree of the floating objects and impurities in front of the grid 14 is relatively large, and at this time, the driving motor 13 has relatively large operating power to adapt to the accumulation degree of the floating objects, so that the accumulated floating objects are cleaned in time, and the cleaning efficiency of the cleaner body 11 is improved; with the cleaning of the floating objects intercepted in front of the grid 14, the water level difference between the front and back of the grid 14 gradually decreases, so that the gear 24 drives the pressure rod piece 27 to reversely deflect, when the pressure rod piece 27 reversely rotates to press the first switch 28, the driving motor 13 is controlled to stop working, and the reciprocating operation is performed.

[0050] In different periods of the river, the water level of the river surface will be different, when the river water level is low, the distance between the floating objects intercepted in front of the grid 14 and the upper side of the bent rail of the cleaner body 11 is relatively large, so that the time for lifting and cleaning the floating objects is relatively long, which will also affect the cleaning efficiency of the floating objects. At this time, through the adjusting assembly 3, when the river water level is low, the first floating body 22 will make the tooth rod 21 relatively move downward, the downward movement of the two side tooth rods 21 can drive the gear 24 to move downward, the first telescopic part 25 is shortened, the downward movement of the front side tooth rod 21 will drive the connecting rod 36 to move downward, and then drive the upper metal sliding sheet 35 to move downward, so that the resistance value of the electric resistance wire 33 connected in the circuit between the upper and lower metal sliding sheets 35 is reduced, so that the operating power of the driving motor 13 is relatively large, so as to improve the cleaning efficiency of the cleaner body 11 when the river water level is low, and the floating objects in front of the grid 14 are lifted and cleaned out in time, so that the cleaning efficiency of the cleaner body 11 is adapted to the height of the river water level, and the applicability of the cleaner body 11 is improved.

The fixed end of the second telescopic piece 48 and the fixed end of the third telescopic piece 49 are movably penetrated through the bottom side of the fixed shell 41. Correspondingly, the bottom side of the fixed shell 41 is provided with a through slot matched with the fixed end of the second telescopic piece 48 and the fixed end of the third telescopic piece 49. The telescopic end of the second telescopic piece 48 and the telescopic end of the third telescopic piece 49 are fixedly provided with a detection piece 410 and a second floating body 411.

[0059] The intermittent assembly 6 comprises a fixed rod 61 fixed on one side of the first block 52, one end of the fixed rod 61 is fixedly provided with a mounting piece 62 which is slidingly arranged in the shell 51, the inner bottom end of the shell 51 is provided with a first guide groove matched with the mounting piece 62, so as to guide and limit the movement of the mounting piece 62, the mounting piece 62 is provided with a fourth switch 63 on one side, the shell 51 is fixedly provided with a reduction motor 64, the pressure sensor 413 located on one side of the third telescopic piece 49 can also be electrically connected with the reduction motor 64 and the reciprocating motor 42, the output end of the reduction motor 64 is fixedly provided with a lead screw 65, the lead screw 65 is rotatably provided with a limiting block 67 fixed on the shell 51 on both sides, the lead screw 65 is threadedly provided with an arc-shaped block 66 which is slidingly arranged in the shell 51, the inner bottom end of the shell 51 is provided with a second guide groove matched with the arc-shaped block 66, so as to guide and limit the movement of the arc-shaped block 66, one side of the arc-shaped block 66 is provided as an arc-shaped end face, so as to conveniently abut against the fourth switch 63, and the limiting block 67 is provided with a limiting switch on the side close to the arc-shaped block 66;

[0060] When the moving piece 45 moves reversely to abut against the third switch 415 and controls the reciprocating motor 42 to stop working, the reduction motor 64 can be controlled to work at the same time, the output end of the reduction motor 64 drives the lead screw 65 to rotate, so that the arc-shaped block 66 moves along the second guide groove to move close to the mounting piece 62, when the arc-shaped block 66 moves to abut against the fourth switch 63, the reduction motor 64 is controlled to stop working, and the reciprocating motor 42 is controlled to work, so as to drive the moving piece 45 and the detection piece 410 to move reciprocatingly again, when the moving piece 45 no longer abuts against the third switch 415, the reduction motor 64 is controlled to drive the lead screw 65 to rotate reversely, so that the arc-shaped block 66 moves reversely to reset, when the arc-shaped block 66 moves reversely to abut against the limiting switch on one side of the limiting block 67, the reduction motor 64 is controlled to stop working, so as to control the detection piece 410 to move reciprocatingly and circularly, so as to further adjust the cleaning efficiency of the cleaner body 11;

[0061] When the river flow velocity is relatively large, the pressure sensor 413 on the side of the third telescopic part 49 can detect a relatively large pressing force, so that the first block 52 moves away from the first electromagnetic block 53 by a relatively large distance, and the power of the speed reducer motor 64 and the reciprocating motor 42 is relatively large. The movement of the first block 52 can drive the synchronous movement of the fixed rod 61, so that the mounting part 62 moves along the first guide groove to approach the speed reducer motor 64. When the river flow velocity is relatively large, the mounting part 62 moves a relatively large distance to approach the speed reducer motor 64, and the power of the speed reducer motor 64 is relatively large, so that the arc-shaped block 66 relatively quickly presses the fourth switch 63. When the river flow velocity is relatively large, the reciprocating cycle movement time interval of the detection part 410 is relatively shortened. In addition, when the river flow velocity is relatively large, the power of the reciprocating motor 42 is relatively large, so that the speed of the reciprocating movement of the detection part 410 is relatively fast. When the river flow velocity is relatively large, the impact of the water flow is also relatively large, which can bring relatively more water surface floating objects. In addition, the relatively large river flow velocity can also make the change of the water surface floating object accumulation amount relatively fast. Therefore, according to the adjustment of the reciprocating movement speed of the detection part 410 and the reciprocating cycle movement time interval according to the river flow velocity, the floating object accumulation degree can be detected in time, and the cleaning efficiency of the cleaner body 11 can be adjusted in time, thereby improving the applicability of the cleaner body 11.
