The park lake is a part of the natural water body. Due to the obvious difference between it and the river course, it is also difficult to clean up the silt under the water of the park lake.

In the prior art, dredgers are generally used to clean the underwater silt of park lakes. Although the purpose of clearing silt can be achieved, it is easy to cause pollution to the water body of the park lake; because the bottom terrain of the park lake is relatively complicated, dredgers cannot be used to clean up the silt. A comprehensive cleaning of the bottom is not effective and the efficiency is low. Due to the large area of the park lake, dredgers cannot handle the corners of the bottom of the lake well, which has certain limitations.
