[0022] The first screw 21 is driven to rotate by the power device 2, driving the mounting plate 3 to move in the regulating tank 1. The first scraper 4 at the bottom of the mounting plate 3 scrapes up the sludge and sediment at the bottom of the regulating tank 1 as the mounting plate 3 moves. At the same time, the second scrapers 5 on both sides synchronously scrape off the attachments on the side walls of the regulating tank 1. When the bottom scraper moves to the other end of the regulating tank 1, the second screw 33 is driven to rotate by the dual-axis motor 32, driving the cleaning plates 34 on both sides to move toward the circulation ports 52 on both sides respectively, and the sludge accumulated on the first scraper 4 is discharged from the circulation ports 52 on both sides to the discharge port 11, completing the cleaning.

[0023] Through the coordinated use of the first scraper 4 and the second scraper 5, the sludge and sediment on the bottom and side walls of the regulating tank 1 can be completely cleaned to ensure the normal operation of the regulating tank 1. At the same time, the cleaning plate 34 is driven to move by the dual-axis motor 32, and the sludge and sediment are discharged from the regulating tank 1 through the flow port 52 and the discharge port 11, thereby avoiding the accumulation of sludge in the regulating tank 1 and secondary pollution, and also saving water resources.

[0024] The side wall of the first scraper 4 is provided with a first chamfer 41 .

[0025] The first chamfer 41 can be provided to effectively prevent sludge from accumulating in the gap between the first scraper 4 and the bottom of the pool, thereby reducing sludge residue and improving the thoroughness of dredging.

[0026] The side wall of the second scraper 5 is provided with a second chamfer 51 .

[0027] The second chamfer 51 can effectively prevent sludge from accumulating in the gap between the second scraper 5 and the pool wall, thereby reducing sludge residue and improving the thoroughness of dredging.

[0030] The side walls of adjacent cleaning plates 34 may abut against each other in the middle of the cleaning groove 31 .

[0031] Adjacent cleaning plates 34 can abut against each other in the middle of the cleaning groove 31, thereby ensuring a tight fit between the cleaning plates 34 and reducing the possibility of sludge leaking from the gaps, thereby improving the efficiency of dredging.

[0032] The working principle of the utility model is as follows: the first screw 21 is driven to rotate by the power device 2, driving the mounting plate 3 to move in the regulating tank 1. The first scraper 4 at the bottom of the mounting plate 3 scrapes up the sludge and sediment at the bottom of the regulating tank 1 as the mounting plate 3 moves. At the same time, the second scrapers 5 on both sides synchronously scrape off the attachments on the side walls of the regulating tank 1. When the bottom scraper moves to the other end of the regulating tank 1, the second screw 33 is driven to rotate by the dual-axis motor 32, driving the cleaning plates 34 on both sides to move toward the circulation ports 52 on both sides respectively, and the sludge accumulated on the first scraper 4 is discharged from the circulation ports 52 on both sides to the discharge port 11, completing the cleaning.

[0033] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
