Electric propulsion device for passenger ferry

Abstract

The invention discloses an electric propulsion device for a passenger ferry, which comprises a storage cell group, a main distribution panel, a direct-current motor, a clutch, a propeller shaft, a propeller, a control cabinet, a charger, a wind driven generator and a resistance box, wherein the direct-current motor is connected with one end of the propeller shaft via the clutch; the other end of the propeller shaft is fixedly connected with the propeller; the storage cell group is electrically connected with the direct-current motor successively via the main switch of the main distribution panel and the resistance box; the wind driven generator is arranged on the superstructure of a ferry body; the output end of the wind driven generator is electrically connected with the main switch of the main distribution panel via one path of input end of a change-over switch; the input end of the charger is electrically connected with the output end of a shore connection box; and the output end of the charger is electrically connected with the storage cell group via the other path of input end of the change-over switch. According to the electric propulsion device for the passenger ferry, which is disclosed by the invention, the current can be regulated by regulating the resistance value so as to regulate the revolving speed of the propeller, and the cost is lower. Wind is used for generating power while the passenger ferry is driven to charge the storage cell group, and the energy supplement to the storage cell group is guaranteed.

Description

technical field

[0001] The invention relates to a ship propulsion device, in particular to an electric propulsion device system for an inland river passenger ferry powered by a storage battery, and belongs to the technical field of ship engineering. Background technique

[0002] At present, under the guidance of the country's policy of vigorously developing energy-saving and environmental protection industries and promoting low-carbon economy, the treatment of oil and sewage pollution from inland river vessels has become a top priority. The development of clean energy ship propulsion devices has become a new way to promote the development of low-carbon economy , plays a very important role in developing green shipping and building low-carbon ships.

[0003] Inland river passenger ferries sail in the inland waters of cities. The ships have short voyages, frequent stops, and many ships in the waterway. The navigation situation is relatively complicated, and the surrounding wa...
