Harbor basin dredging device driven by tidal current energy

Abstract

The invention discloses a harbor basin dredging device driven by tidal current energy, which comprises a stirring mechanism capable of knowing the rising tide and ebb tide of water in the harbor basin water area to rotate, a driving mechanism connected with the stirring mechanism, and a catamaran, the catamaran The water area between constitutes the dredging water area, the stirring mechanism is located in the dredging water area, and the driving mechanism is located on the dam of the harbor basin. The stirring mechanism includes a connecting shaft, an impeller is arranged on the connecting shaft, and more than one layer of The propeller blades that can rotate with the high tide are connected with a rotating disc at the lower end of the impeller, and dredging claws are distributed on the rotating disc in a circular motion. The upper end of the connecting shaft is provided with a connecting plate on the catamaran, and the connecting shaft The upper end is hinged with the drive mechanism. The invention utilizes the tidal energy in the natural environment as power to agitate the silt on the harbor basin to avoid accumulation, so as to facilitate cleaning and reduce labor costs.

Description

technical field [0001] The invention belongs to the technical field of mechanical dredging mechanisms, in particular to a harbor basin dredging device driven by tidal current energy. Background technique [0002] In today's world of economic globalization, 90% of the world's trade passes through the sea, and 70% of the world's economic activities take place in coastal areas. To build China's own transnational economic system through the sea, the port is particularly important. . The harbor basin is the water area in the port for ships to berth, operate, leave and turn around. The harbor basin must have sufficient area and water depth, while the harbor basin at the estuary or adjacent to the estuary on the coast has more complicated water flow conditions, especially the backflow is more serious. Due to the high sand content of the offshore current, it is easy to deposit in the harbor basin under the action of backflow, which affects the normal use of the harbor basin. [0...

AI Technical Summary

Problems solved by technology

The above method requires a lot of manpower and material resources, and dredging ships or dredging pumps are needed. For the port, the economic benefits of such development are not obvious. At the same time, there are some harbor basins due to the height of the embankment, which leads to various types of problems. It is inconvenient for dredgers to drive into the harbor basin for dredging operations. Therefore, how to design a dredger that can solve the above-mentioned need for a large number of manual operations, which leads to high labor costs, complex structure, inconvenient cleaning, and utilizes the tidal energy in the natural environment, that is, sea water. The automatic mud cleaning mechanism driven by high tide and low tide is particularly important
