Description

Technical Field

[0001] The present invention relates to the technical field of new energy ships, and in particular to an extended-range double-string outboard electric engine room ship-type multifunctional ship and a non-powered aquaculture operation ship. Background Art

[0002] Electric ships are a type of electric vehicle, which are ships propelled by electricity generated by batteries. Electric ships are developed on the basis of internal combustion engine ships. There is no internal combustion engine on board, and all energy comes from batteries, relying on battery power for propulsion. The development of electric ships has benefited from the success of lithium-ion batteries in the electric vehicle industry, and this battery technology has become the primary driving factor for the development of electric ships. At present, major breakthroughs have been made in the key technologies of lithium-ion battery energy storage systems at home and abroad, and a large number of research results have been achieved in the fields of ship power system networking technology, ship electric propulsion technology, and high-power power grid connection technology. At present, the number of electric ships under construction and operation in the world has exceeded 300, including ferries, offshore ships, passenger ships, tugboats and other ship types. Electric ships have the advantages of green environmental protection, can achieve zero emissions, and have the advantages of safety and convenience, high propulsion efficiency, low use cost, and no diesel leakage. It is an effective choice for the green transformation of inland waterway shipping. In recent years, as the country has increased its efforts to promote the application of new energy, the proportion of new energy use in the ship industry has gradually increased, and the market size of the electric ship industry has also maintained rapid growth. The downstream demand of my country's electric ship industry is mainly inland ships, which are used for short-distance transportation or tourism. In recent years, with the continuous growth of road and railway mileage, the inland shipping market has been under great competitive pressure. Therefore, the number of domestic inland ships has been on a downward trend, and old ships have been continuously eliminated. Although the number of inland ships is declining, the demand for electric ships will continue to grow in the future. Whether it is new electric ships or old ships transformed into electric ships, there will be a lot of room for development in the market. As the proportion of electric propulsion systems gradually increases, the feasibility of converting its power source from diesel engines, gas turbines or steam turbines to lithium-ion batteries or fuel cells is gradually increasing. With the tightening of environmental protection policies and the continuous decline in the price of power battery systems, the penetration rate of pure electric ships or hybrid ships is gradually increasing, especially in the fields of urban ferries, sightseeing boats, inland cargo ships and port tugboats. The use scenarios will become clearer. The lithium electrification penetration rate of electric ships in my country is expected to reach 10.68% in 2029. From the perspective of technology and practicality, electric ships are subject to battery life, charging speed, and the distribution of charging facilities. For some long-distance voyages and large-scale coastal and ocean-going transportation, electric ships are difficult to meet actual needs. However, in inland waterway shipping for short- and medium-distance transportation and small- and medium-volume transportation, electric ships have a bright future. Therefore, the increase in the output of electric ships will become an industry trend in the future. In recent years, with the increasing world energy consumption and the continuous intensification of environmental pollution, the concept of green and sustainable development has been deeply rooted in the hearts of the people. Similar to new energy vehicles, in the field of ships, the gradual maturity of power battery technology and the continuous decline in costs have provided the basic conditions for the development of the electric ship industry, and electric ships have gradually become the "new favorite" of the green shipping market.At present, electric boats have occupied an important position in the fields of inland river ferries, short-distance passenger ships, sightseeing boats and small yachts, but have not been widely used in the fields of short-distance and medium-sized transportation, and are still in a blank stage in the field of ocean transportation. In the future, with the rapid development of science and technology and the gradual improvement of relevant policies and regulations, electric boats will still have a long way to go to be widely used in the fields of short-distance and medium-sized transportation, and achieve a zero breakthrough in the field of ocean transportation.

[0003] Traditional diesel and gasoline engine powered yachts have large engine power, loud noise, low efficiency and serious environmental pollution.

[0004] In summary, the present invention designs an extended-range double-string outboard electric engine room boat-type multifunctional boat and a non-powered aquaculture operation boat. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a multifunctional boat with an extended-range double-outboard electric engine room and a non-powered aquaculture operation boat. The towing connection platform of the multifunctional pusher boat and the towing connection platform of the aquaculture operation boat are firmly and reliably connected together through multiple sets of pin interlocking devices of the multifunctional boat with an extended-range double-outboard electric engine room, so as to push the non-powered aquaculture operation boat in a gapless, stable and collision-free manner.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an extended-range double-outboard electric engine room boat-type multifunctional ship and an unpowered aquaculture operation boat, including a multifunctional pusher boat and an aquaculture operation boat, the multifunctional pusher boat is connected to the aquaculture operation boat through a pin column interlocking device, the multifunctional pusher boat includes a main deck, a maintenance deck extending from the rear deck of the main deck is connected to a detachable propeller hanging groove by bolts, a permanent magnet motor outboard engine is arranged on the detachable propeller hanging groove, a multifunctional pusher boat towing connection platform is arranged at the front end of the main deck, the multifunctional pusher boat towing connection platform is connected to the aquaculture operation boat towing connection platform on the aquaculture operation boat through a pin column interlocking device, and a stern gable is arranged at the front end of the aquaculture operation boat towing connection platform.

[0007] Preferably, the end surface of the multi-functional pusher boat towing connection platform completely rests on the stern gable of the aquaculture operation boat towing connection platform.

[0008] Preferably, the pin interlocking device is provided in multiple groups.

[0009] The present invention has the following beneficial effects:

[0010] 1. The end face of the towing connection platform of the multifunctional pushboat is completely against the stern gable of the aquaculture operation boat. The towing connection platform of the multifunctional pushboat and the towing connection platform of the aquaculture operation boat are firmly and reliably connected together through five sets of pin interlocking devices. At the same time, the pin interlocking device has a sufficiently long sliding length to ensure that when the hull of the aquaculture operation boat is lowered at the maximum load, the towing connection platform of the aquaculture operation boat can slide freely on the pin of the pin interlocking device.

[0011] 2. Traditional power boats are towed, with the power boat in front and the tugboat in the back. In the extended-range double-outboard electric engine room ship-type multifunctional boat and the unpowered aquaculture operation boat of the present invention, the pusher boat of the extended-range double-outboard electric engine room ship-type multifunctional boat is at the back, and the towing connection platform of the multifunctional pusher boat and the towing connection platform of the aquaculture operation boat are firmly and reliably connected together through multiple sets of pin interlocking devices of the extended-range double-outboard electric engine room ship-type multifunctional boat, so as to push the unpowered aquaculture operation boat in a gapless, stable and collision-free manner. The propeller of the double-outboard permanent magnet electric hanging propeller of the extended-range double-outboard electric engine room ship-type multifunctional boat is at the end of the entire connected ship. When driving, the thrust generated is the largest, and there is no need for a sufficient distance between the power boat and the tugboat to reduce the thrust of the propeller acting on the tugboat and increase the resistance. In addition, the extended-range double-outboard electric engine room boat-type multifunctional boat of the present invention is a pusher boat type, with no distance between the two boats, which are connected as one, and the turning radius is more than half smaller than that of the tugboat type, which is beneficial to operations in the breeding area and can ensure that the middle waterway in the breeding area is narrower and the breeding area is larger.
