Description

An externally-mounted electric propulsion device for ship hull

Technical field

The invention relates to an externally hung electric propulsion device for a ship body.

Background technique

With the rapid development of society, the number of fuel (diesel or gasoline) motor vehicles and ships has increased rapidly. While improving people's lives, it also brings serious air pollution. In recent years, the state has adopted various measures to reduce air pollution, and particularly vigorously promoted support policies for new energy vehicles. Therefore, in just a few years, the battery, motor, control system, and vehicle technology are all developing rapidly, and the proportion of electric vehicles is also rapidly increasing. Compared with automobiles, the pollutant discharge per unit horsepower of ships is far more serious than that of automobiles. According to the "Study Report on Air Pollutants from Ships in Jiangsu Province" published by Jiangsu Environmental Testing Center in December 2014, a very detailed investigation has been conducted on my country's water transport situation and ship pollution. Compared with the ships of the world, my country's ship engines have obvious defects, and low-end diesel engines are widely used, so there is a big gap with the international level. In terms of air pollution from marine diesel engines, my country’s emissions are much higher than those of developed countries in Europe and America. With the further development of my country's economy, ship pollution will become more and more serious. Therefore, how to control and reduce ship exhaust emissions is extremely urgent.

Of course, out of pollution control, a better method that can be thought of is to use an electric-driven hull (electric boat) with built-in batteries to replace fuel-fueled motor boats, but considering the long continuous cruising time of commercial ships and the problem of continuous travel The cost of batteries is expensive. If built-in batteries are used, they cannot be applied to the application environment of commercial ships. Because the built-in battery solution is necessary to use a large-capacity battery in order to ensure a longer voyage, the large-capacity battery is inconvenient and expensive to replace on the one hand, and on the other hand, the charging time is very long, which cannot guarantee the life cycle of the car ferry. effectiveness. In addition, it is obviously very unrealistic to retrofit all the current types of hulls with electric power or directly use electric boats to replace the existing ships. Not only will the cost of modification be high, but also a large number of existing hulls will be discarded, and a lot of resources will be destroyed. waste. Therefore, there is an urgent need for a better solution to the current ship pollution problem.

Summary of the invention

The purpose of the present invention is to provide an externally mounted electric propulsion device for the hull, which can solve the current pollution problem of fuel-fueled motor boats and the endurance problem of electric boats with built-in batteries, save energy, and is easy to implement and promote.

The technical solution of the present invention is: an externally mounted electric propulsion device for the hull, which is characterized by an independent externally mounted device, including a navigation floating body, more than one electric propeller and its driver installed on the navigation floating body, and The navigating floating body is used to power batteries for the electric propeller and its driver; the navigating floating body is connected to the tail of the current hull through a detachable external connection mechanism to drive the hull, or connected to the front of the hull to pull the hull to travel; also It includes a peripheral controller arranged on the hull of the ship and connected to the driver of the electric propeller through a wired or wireless manner, and the peripheral controller is used to control the forward and reverse rotation and the speed of the electric propeller.

When more than one electric propeller is provided, they can be arranged side by side in the longitudinal or transverse direction on the navigation floating body, or arranged in a high and low position, and the present invention has no limitation on this.

It should be pointed out that when the hull mentioned in the present invention is the hull of an existing ship with steering rudder, for example, the hull of an existing engine-powered propulsion ship, including existing fuel oil (diesel and gasoline) motor boats and electric vehicles with built-in batteries Ship, or wind-propelled ship (sailing), etc.; under this premise, the electric propeller is a fixed-angle electric propeller, and the traveling direction of the hull is controlled by its own steering rudder. This design scheme makes the peripheral controller on the hull only used to control the forward and backward power of the external electric propulsion device.

Under normal circumstances, the present invention performs docking when the hull is docked. Of course, other vessels can also be towed to the navigation position of the hull for docking operations. In order to facilitate the operation, it is more preferable that in the present invention, a cockpit is provided on the navigation floating body, and a built-in controller electrically connected to the driver of the electric propeller is provided in the cockpit, and the built-in controller is used to control the electric propeller. Forward and reverse rotation and speed. The design of the cockpit facilitates the direct control of the external electric propulsion device by the personnel, and also facilitates the docking operation of the sailing floating body and the hull, and the connection and debugging of the external controller and the electric propeller drive.

Of course, it should be pointed out that the hull of the present invention can be the hull of a manpower propelled boat (such as a rowing boat) in addition to the hull of the current engine-powered propulsion boat and wind propulsion boat mentioned above; or the hull of an unpowered boat. The hull, such as the hull of a barge, or the hull of other non-self-propelled ships that are specially manufactured to carry cargo people. Such hulls usually do not have steering rudders;

Under this premise, the electric propeller in the present invention is designed as an angle-rotating electric propeller, and the peripheral controller can also control the steering angle of this type of angle-rotating electric propeller, thereby controlling the external electric propulsion device itself and its The direction of travel of the driven hull. It should be said that the electric propeller on the external electric propulsion device adopts the angle-rotating electric propeller design, which gives the external electric propulsion device enough freedom of navigation and facilitates its docking with the hull, which is especially convenient when the hull is sailing (non-leaning). Shore state) docking. Obviously, controlling the sailing direction of the external electric propulsion device can control the sailing direction of the hull pushed or pulled by it. Of course, it needs to be explained that even if the angle-rotating electric propeller is used, in actual navigation, for the current ships with navigation and steering capabilities, such as the aforementioned engine-powered propulsion ships and wind-propelled ships with steering rudders, The navigation direction of its hull can still be controlled by its own steering rudder.

Of course, whether it is an angle-fixed electric propeller or an angle-rotating electric propeller, it is a relatively mature technology at present, including its driver and connection control technology with peripheral controllers are all well-known technologies in the industry.

On this basis, in order to further streamline the structural design of the externally mounted electric propulsion device, we have preferably designed an angle-rotating electric propeller with the following structure:

More preferably, the navigation floating body in the present invention is provided with a cockpit, and a built-in controller electrically connected to the driver of the electric propeller is provided in the cockpit, and the built-in controller is used to control the forward and reverse rotation of the electric propeller. Speed, and steering angle. Similarly, the design of the cockpit facilitates the direct control of the external electric propulsion device by the personnel, and also facilitates the docking operation of the sailing float and the hull, and the connection and debugging of the external controller and the electric propeller drive.

Further, the detachable external connection mechanism in the present invention is one of a spring buckle mechanism, a buckle mechanism, a lever mechanism, a manual mechanical lock mechanism, an electromechanical lock mechanism, and an electromagnetic lock mechanism, including The male end connecting mechanism fixed on the navigating floating body and the female end connecting mechanism used to fix the hull of the current ship and cooperate with the male end connecting mechanism, or the detachable external connecting mechanism includes two fixed to the navigating floating body and the hull. There are two connecting frames or connecting plates, and the two connecting frames or connecting plates are connected and fixed by bolts or ropes.

The design purpose of the detachable external connection mechanism is to facilitate quick docking and reliable fixation between the external electric propulsion device and the hull. The design forms of the male-end external connection mechanism and the female-end external connection mechanism and their matching structures are various, and they are all common quick connection mechanisms in the industry. The examples above are not exhaustive.

Taking the existing spring buckle mechanism as an example, it is composed of a spring buckle body and a connecting ring or connecting rod that cooperates with it. We use the spring buckle body as a male end external connection mechanism to fix it or integrally design it on the sailing float. The connecting ring or connecting rod is fixed on the hull of the ship as a female external connecting mechanism. In this way, the connection can be completed only by snapping the connecting ring or the connecting rod into the body of the spring buckle.

Or take the existing buckle mechanism as an example, which is composed of a connecting rod and a U-shaped buckle for interference clamping. We use the U-shaped buckle as a male end external connection mechanism to fix it or integrally design it on the navigation floating body. The connecting rod is welded on the hull of the ship as a female external connection mechanism. In this way, the connection can be completed by simply snapping the connecting rod into the U-shaped buckle.

Further, the present invention adopts at least two or more of the detachable external connection mechanisms, and at least two of the detachable external connection mechanisms are horizontally distributed with equal height or offset. It is used to reduce the dimensional freedom of the external electric propulsion device in the horizontal direction and improve the stability of its connection with the hull of the ship.

Further, in the present invention, a charging module connected to the power battery is provided on the navigation floating body, the charging module includes a power monitoring module, and the peripheral controller is provided with a low power alarm device electrically connected to the power monitoring module and Power display device.

The purpose of this design is to facilitate the replacement between two external electric propulsion devices. The actual operation process is as follows: When the electric energy of the external electric propulsion device A that drives the hull is reduced and needs to be replaced, it is controlled by the staff or personally Drive the external electric propulsion device B close to the external electric propulsion device A, fix the tails of the external electric propulsion device A and the external electric propulsion device B through the detachable self-connecting mechanism, and then untie the detachable external connecting mechanism to make The external electric propulsion device A is separated from the hull of the ship, and the cable electrical connector of the external controller is disconnected at the same time (the wireless method does not have this problem); then, the external electric propulsion device A and B are controlled by the staff to turn around 180 degrees. , And then the staff will fix the external electric propulsion device B and the hull through a detachable external connection mechanism, and connect the electrical connector of the external controller, and finally control by the staff or return to the external electric propulsion device A to drive it personally Return home.

The wired connection mode of the peripheral controller and the electric propeller driver in the present invention refers to the direct connection of the two communication lines through a cable with electrical connectors, and the wireless connection mode refers to infrared communication and radio communication. , Or use existing wifi, 4G, 5G and other network communication methods for remote connection control.

The advantages of the present invention are:

1) The present invention is an independent external hanging device, which can be used as the navigation power device of any current ship, especially when the fuel oil motor ship applies the present invention, it can turn off its own fuel oil drive device to achieve zero emission and noiseless operation, which is very good. To solve the current pollution problem and noise problem of ships. The present invention can effectively solve the problem of endurance for the current electric ships with built-in batteries, because the invention has the characteristics of quick replacement, can continuously provide driving force for the ship hull, and reduces the cost of purchasing and replacing expensive built-in batteries for the ship. Cost input.

2) The present invention can be widely applied to existing ships in any waters such as inland rivers, lakes, reservoirs, etc., and has a wide range of applications. Especially when the present invention is applied to the hull of an unpowered ship, it can gradually reduce the cost of current fuel-fueled motor ships. It can be used to solve the pollution and noise problems of ships.

3) Under the premise of the same power (driving power) and use conditions (round-trip times and round-trip voyage), compared with the ships driven by the present invention, the traditional fuel-fueled motor boats will greatly save annual operating costs. Take the current 800-ton diesel motor ship as an example. It uses two 200kw diesel engines, and the external electric propulsion device of this scheme is equipped with two 200kw motors as power (electric propellers), and is equipped with 16 sets of batteries. Supply energy for each motor, each battery is 100 kWh, worth 100,000 yuan, then the energy consumption cost of the two is compared in the following table:

It can be seen from the above table that the electricity bill per unit mileage is about 28% of the gas bill, saving nearly 72%. Each set of batteries has 100 kilowatt-hours of electricity and is worth 100,000 yuan. Each electric propeller of the external electric propulsion device is equipped with 16 sets of batteries, with a total value of 1.6 million yuan. According to the calculation of the battery life 3000 times, 16 sets of batteries are replaced every two years, worth 1.6 million yuan, and the annual depreciation cost is 800,000 yuan. Calculated by operating 300 days a year, the ship driven by the invention can save about 1.74 million yuan per year.

4) When the present invention is actually used, it is only necessary to make very small changes to the hull of the current ship, add the female end connecting mechanism or connecting plate or connecting bracket of the quick-release external connecting mechanism, and add an external controller. The transformation cost is low, and it is easy to implement and promote.

5) When the present invention is used, the power and operating mechanism of the current hull are not changed at all. When the external electric propulsion device of the present invention is not used, it can still sail freely and is still driven by the original driver without professional operation.

6) The docking, assembly and disassembly between the present invention and the hull of an existing ship is extremely convenient, and the replacement can be almost completed in a few minutes without stopping the ship, thereby greatly improving the endurance.

7) The present invention is an independent external hanging device relative to the hull. In case the power battery in the present invention accidentally catches fire or even explodes, the hull can be detached without endangering the hull itself, compared to directly installing the power battery on the hull The current electric boat with built-in battery has higher safety in use.

Each buckle mechanism in this embodiment is composed of a connecting rod 18 and a U-shaped buckle 19 for interference clamping. We designed the U-shaped buckle 19 as the male end external connection mechanism on the head of the two boat-shaped floating bodies 1c, and welded the two connecting rods 18 as the female end external connection mechanism to the tail of the hull 4. The actual connection only needs to be connected The rod 18 is clamped into the U-shaped buckle 19 to complete the connection, as shown in Figs. 5 and 6.
