Description

Externally-hung electric propulsion device for ship body

Technical Field

The utility model relates to an outer hanging electric propulsion unit for hull.

Background

With the rapid development of society, the number of fuel (diesel oil or gasoline) motor vehicles and boats is increased extremely rapidly, and the air pollution is also serious while the life of people is improved. In recent years, various measures are taken by the nation to reduce air pollution, and the policy of supporting new energy automobiles is particularly and vigorously promoted. Therefore, in short years, the technologies of batteries, motors, control systems and whole vehicles are rapidly developed, and the proportion of electric vehicles is rapidly increased. The discharge capacity per horsepower of a marine vessel is far more severe than that of an automobile. According to a research report on atmospheric pollutants of ships in Jiangsu province, which is published by the environmental detection center in Jiangsu province in 2014 12 months, the water transportation condition and the ship pollution in China are investigated in great detail. Compared with ships in the world, the ship engine in China has obvious defects, and low-end diesel engines are widely applied, so that the difference from the international level exists. In the aspect of air pollution of marine diesel engines, the emission of China is far higher than the level of developed countries in Europe and America. With the further development of economy in China, the pollution of ships is more and more serious, so that how to control and reduce the exhaust emission of ships is urgent.

Since 'twelve five', the party center has paid serious attention to the problem of atmospheric pollution. The 'Notification of guidance suggestions of departments such as the department of office of State Council for forwarding environmental protection department and the like about promoting the air quality of the regional air quality improvement of the air pollution joint defense work' (No. 2010) indicates that in recent years, regional air pollution problems such as acid rain, haze, photochemical smog and the like in some regions of China are increasingly prominent, the health of the masses is seriously threatened, the environmental safety is influenced, practical measures are required to be taken in various regions, the regional air pollution joint defense joint control is promoted, and the regional air quality is improved. The province government of Jiangsu province is thoroughly implemented with the requirements of the center of the Party and the national institutes, and the opinion on the implementation of the blue sky engineering to improve the atmospheric environment of the province government (Su government No. 2010) 87 is issued, so that the research on related subjects is actively promoted, and the technical support is provided for management. With the deep development of emission reduction work, the tail gas pollution of motor vehicles is effectively controlled, the emission reduction space of atmospheric pollution is gradually narrowed, but the haze pollution condition of China is still very serious, which shows that the atmospheric pollutant emission of China still keeps a high-pressure situation, and a new emission reduction potential needs to be deeply excavated. As an important source of atmospheric pollution, ship pollution is also gradually brought into the focus of joint defense and joint control in areas. In 9 months in 2013, the requirement of the air pollution prevention action plan (No. 2013) 37 issued by the State department on the development of pollution control of non-road mobile machinery and ships such as engineering machinery and the like is met. "

Of course, in terms of pollution control, a better method is conceivable to replace an oil-fired power boat with an electrically-driven hull (power boat) with a built-in battery, but considering the problem of continuous cruising with a long single-trip time of a commercial ship and the problem of high cost of the battery, the use of the built-in battery is not suitable for the application environment of the commercial ship. The scheme of the built-in battery is necessary to adopt a large-capacity battery in order to ensure a long navigation mileage, but the large-capacity battery is inconvenient and expensive to replace on one hand, and on the other hand, the charging time is very long, so that the service cycle and the efficiency of the automobile ferry cannot be ensured. In addition, if various existing ship bodies are electrically transformed or an electric ship is directly adopted to replace an existing ship, the transformation is obviously unrealistic, the transformation cost is high, a large number of existing ship bodies are abandoned, and a large number of resources are wasted. Therefore, a better solution for solving the current ship pollution problem is urgently needed.

Compared with the manually operated buckling mechanism in the embodiment 1, the operation is obviously more convenient and labor-saving.

Example 4: embodiment 4 is the same as the design structure of embodiment 1 (the sailing float 1, the electric propeller 2, and the peripheral controller 5) as a whole, except for the difference between the detachable external connection mechanism and the detachable internal connection mechanism. As shown in fig. 10, the detachable external connection mechanism in this embodiment is still an electromechanical locking mechanism, and two electromechanical locking mechanisms arranged in parallel at equal heights in the transverse direction are still used to complete the connection between the floating body 1 and the tail of the hull 4 of the diesel ship, as shown in embodiment 1.

Example 5: embodiment 5 is the same as embodiment 1 in the design structure (the navigation float 1, the electric propeller 2, and the peripheral controller 5) as a whole, and differs only in the difference between the detachable external connection mechanism and the detachable internal connection mechanism. As shown in fig. 11, the detachable external connection mechanism in this embodiment is still an electromechanical locking mechanism, the female connection mechanism is two connection rods 18 welded to the tail end of the hull 4 of the diesel ship, and the male connection mechanism is a dual electric locking device provided on the navigation floating body 1 and capable of locking the two connection rods 18 at the same time. As shown in fig. 11, the dual electric locking device is located between two connecting rods 18, and is composed of a central bracket 28, a gear driving motor 29, a gear 30, two racks 32 disposed in corresponding rack guide rails 31, and a U-shaped locking hook 26. The gear driving motor 29 is disposed above the central bracket 28, and has an output shaft with a fixed gear 30, and two rack rails 31 are disposed in a central symmetry manner with respect to a gear 32 and are parallel to each other. A rack 32 in a rack rail 31 engages with the gear 30. The extended section of the end of the rack 31 is welded and fixed with a U-shaped lock hook 26 which respectively acts with the two connecting rods 18. Compared with the detachable external connection mechanisms related to the previous embodiments 1-4, the detachable external connection mechanism in the embodiment has higher mechanism execution efficiency, and can obtain higher connection reliability and stability by being used alone. The detachable internal connecting mechanism is the same as the detachable external connecting mechanism, namely, the connection of the tail ends of the two navigation floating bodies 1 is realized by adopting the electromechanical locking mechanism.
