Technical Field
[0001] The present application relates to the technical field of new energy utilization, and in particular to a marine booster-generator. Background Art
[0002] With the increasing shortage of fossil energy and increasingly stringent international emission regulations for ships, ship owners and ship designers are gradually paying attention to ship energy conservation and emission reduction technologies, including the use of wind energy for auxiliary propulsion. During the navigation of ships, wind energy is the most easily developed and utilized renewable energy, which can provide a certain thrust for ships and effectively reduce ship energy consumption and emissions. In the future, more and more ships will use sailing technology to assist navigation.
[0003] At present, there are two main ways for ships to use wind energy: wind power generation and sailing, which are suitable for different sea routes and ship operation conditions, but the current sailing devices generally cannot take into account the use of these two methods. Therefore, it is necessary to design a marine propulsion-generator that can not only perform wind propulsion, but also realize wind power generation, and can integrate wind power generation and wind propulsion.

[0029] The present application provides a marine booster-generator device, Figure 1 and Figure 2 The overall structure diagrams of the marine booster-generator in the present application when in the booster mode and the generator mode are shown respectively, as shown in FIG. Figure 1 and Figure 2As shown, it includes a base 4, a power generation-driving device, and a device body fixedly mounted on the base 4. The device body includes a plurality of blades 2, an upper top plate 1, a first rotating shaft 6, and a plurality of second rotating shafts 7. The upper top plate 1 is detachably arranged on the top of the first rotating shaft 6. The first rotating shaft 6 is fixedly mounted at the center of the base 4 in the vertical direction, and the first central cylinder 6 is connected to the power generation-driving device. The second rotating shaft 7 is arranged inside the blade 2, and a plurality of the second rotating shafts 7 are evenly distributed along the circumferential direction of the first rotating shaft 6.
[0030] At the same time, the main body of the device has a boosting form and a power generation form. When the main body of the device is in the boosting form, it is in the boosting mode. Several blades 2 are connected by rotating to form a rotating drum. The upper top plate 1 is fixedly connected to the first rotating shaft 6 and several second rotating shafts 7. The power generation-driving device drives the first rotating shaft 6 to rotate and drives the rotating drum to rotate around the first rotating shaft 6. When the main body of the device is in the power generation form, it is in the power generation mode. Several blades 2 are separated and connected to the first rotating shaft 6. Several blades 2 rotate and drive the first rotating shaft 6 to rotate.
[0031] Furthermore, the device body also includes a rotating bearing 5, which is coaxially arranged with the base 4 and installed between the base 4 and a plurality of the blades 2. The inner ring of the rotating bearing 5 is fixedly connected to the base 4, and the outer diameter of the rotating bearing 5 is the same as the outer diameter of the rotating drum.
[0032] Furthermore, the device body includes a limiter 3 coaxially arranged with the base 4, the base 4 is provided with a first groove and the limiter 3 is installed in the groove, the limiter 3 is a circular ring structure and can move along its axial direction, the inner diameter of the limiter 3 is equal to the outer diameter of the rotating drum, and when the device body is in the boost mode, it can effectively prevent several of the blades 2 from separating.
[0033] Furthermore, a plurality of the second rotating shafts 7 are fixedly mounted on the outer ring of the rotating bearing 5 .
[0034] Furthermore, the number of the blades 2 can be adjusted according to actual operating conditions.
[0035] In some preferred embodiments of the present application, the cross-section of the blade 2 is arc-shaped and has a uniform thickness, and the concave surfaces of several blades 2 are all facing the same direction. At the same time, the blade 2 is an axisymmetric structure, and the shape and size of the end of the blade 2 along the horizontal direction are adapted to the outer wall of the first rotating shaft, such as Figure 2 and Figure 3As shown, the end connected to the first rotating shaft 6 can be adjusted according to different wind directions. The arc-shaped streamlined design of the blade 2 can improve the resistance to wind resistance, effectively improve the efficiency of wind power generation, and also reduce noise and save materials.
[0036] Furthermore, the blade 2 is made of lightweight materials such as aluminum-lithium alloy and carbon-based composite materials.
[0037] In some preferred embodiments of the present application, the power generation-drive device is a permanent magnet synchronous motor. When electrical energy is converted into mechanical energy, the power generation-drive device exhibits the working characteristics of an electric motor, drives the drum to rotate, and assists the ship; when mechanical energy is converted into electrical energy, the power generation-drive device exhibits the working characteristics of a generator. The permanent magnet synchronous motor integrates power generation and drive functions, and has the advantages of simple structure, small size, high efficiency, and high power factor.
[0038] Specifically, when the device body is in the boost mode, Figure 1 As shown, several blades 2 are connected end to end to form a rotating drum, the upper top plate 1 is fixedly connected to the first rotating shaft 6 and several second rotating shafts 7, the power generation-drive device is connected to the first rotating shaft 6, and the stopper 3 rises from the first groove of the base 4 to the upper part of the base 4 until the inner wall of the stopper 3 is completely in contact with the outer wall of the rotating drum, thereby preventing several blades 2 from separating. At this time, the power generation-drive device starts to work, the power generation-drive device drives the first rotating shaft 6 to rotate, the first rotating drum 6 drives the upper top plate 1 and then drives the second rotating shaft 7 to rotate, and finally several blades 2 rotate around the first rotating shaft 6, and the ship is boosted by the Magnus effect.
[0039] Furthermore, if Figure 5 As shown in the figure, the Magnus effect, that is, when the lateral wind passes through the rotating drum, the velocity field of the fluid around the drum changes due to the existence of viscous force. According to Bernoulli's principle, the change of the velocity field will cause the pressure field in the flow field to change. The pressure at the end with high speed decreases, and the pressure at the end with low speed increases, thus forming a pressure difference, and thus forming a lateral force in the direction perpendicular to the lateral wind. By adjusting the rotation direction of the drum according to the wind direction, the direction of the lateral force can be controlled, so that it can form a boost in the direction of the ship's advance.
[0040] Specifically, when the device body is in the power generation mode, Figure 4As shown, several blades 2 rotate and separate, and the side of the blade 2 along its axial direction is connected to the first rotating shaft 6, and the upper top plate 1 is removed from the main body of the device. At the same time, the outer wall of the first rotating shaft 6 is provided with a second groove matching the blade 2, and the side of the blade 2 is matched with the second groove to achieve the fixed connection between the blade 2 and the first rotating shaft 6. The stopper 3 is lowered into the first groove of the base 4, and the wind force drives several blades 2 to rotate, and several blades 2 further drive the first rotating shaft 6 to rotate. At the same time, the first rotating shaft 6 is connected to the power generation-driving device. At this time, the main body of the device forms a power generation device, which converts wind energy into mechanical energy and then into electrical energy.
[0041] In some preferred embodiments of the present application, due to the unstable wind force, an energy storage system is also installed. The energy storage system is electrically connected to the base 4 and is used for energy storage. The energy storage system can effectively meet the power demand of the onboard facilities and equipment to ensure the normal operation of the ship.
[0042] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
