Submersible Pond Desilting Robot with Lead Screw Control

The patent replaces the traditional mechanical underwater dredging machine with a robotic system that uses a lead screw mechanism for precise positioning and control. The robot can accurately control the depth and thickness of silt removal through the lead screw's mechanical advantage, while the suction pump system removes silt without disrupting the aquatic environment, thus resolving the contradiction between adaptability and ease of operation.

The patent changes the operational parameters by using a controlled robotic system with adjustable suction power and depth control through the lead screw mechanism. This allows precise control of silt removal thickness and rate, preventing water pollution while maintaining the ability to work underwater without affecting farming operations.

The patent extracts the water removal step from the traditional dry desilting process. Instead of pumping out water to access silt, the robot uses its suction pump to directly extract silt from the underwater environment. This maintains high productivity in silt removal while eliminating the need to drain pond water, thus preserving normal farming operations.

The patent introduces an intermediary suction pump system that allows silt removal to occur underwater without needing to remove water first. The pump acts as a mediator between the silt and the external environment, enabling efficient silt extraction while maintaining the aquatic habitat necessary for fish and shrimp farming.
