Dredging device for harbor basin and based on tidal current energy driving

Abstract

The invention discloses a dredging device for a harbor basin and based on tidal current energy driving. The dredging device for the harbor basin and based on tidal current energy driving comprises a stirring mechanism capable of obtaining the tide rising and falling conditions of water in a harbor basin water area to rotate, a driving mechanism which is connected with the stirring mechanism and acatamaran, the water area between the catamaran forms a dredging water area, the stirring mechanism is located in the dredging water area, the driving mechanism is located on a harbor basin dam, the stirring mechanism comprises a connecting shaft, an impeller is arranged on the connecting shaft, more than one layer of propeller blades capable of perform rotation along with tide rising are longitudinally distributed on the impeller, the lower end of the impeller is connected with a rotating disc, dredging claws are distributed on the rotating disc in a circular motion mode, a connecting plate which is located on the catamaran is arranged at the upper end of the connecting shaft, and the upper end of the connecting shaft is hinged with the driving mechanism. According to the dredging devicefor the harbor basin and based on tidal current energy driving, the tidal energy in the natural environment is used as power and stirring sludge on the harbor basin is carried out to avoid accumulation, so that the effects of facilitating cleaning and reducing the labor cost are achieved.

Description

technical field [0001] The invention relates to a harbor basin dredging vehicle mechanism, which uses a Savonius impeller to capture tidal energy, and 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 ocean, and 70% of the world's economic activities take place in coastal areas. The port is particularly important in building China's own transnational economic system with the ocean as the channel. . 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 curr...

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
