Description

Technical Field

[0001] The present invention relates to the field of electric ships, and in particular to a ship mooring charging device and an energy replenishment method thereof. Background Art

[0002] The navigation of pure electric ships relies on power supply from lithium batteries, storage batteries or nickel-metal hydride batteries. After the ship leaves the port, the battery system serves as the main energy source for the ship's power system and domestic electricity. Its cruising range depends on the power of the battery pack. However, due to problems such as battery performance, the need for charging and replenishment, and short cruising range, pure electric ships cannot be widely used in medium and long-distance voyages. In the prior art, the charging methods for electric ships are relatively limited. The most common charging piles have many rigid conditions. Solar charging and wind charging are affected by environmental factors, and the operation and maintenance costs are high. Therefore, a device is designed to charge and replenish the hull during shipping. Since the propeller structure coupling device of the electric ship mostly uses a non-rigid coupling to avoid excessive force on the propeller shaft in the water, the charging during shipping needs to provide basic energy conversion through the kinetic energy of the propeller, so it is necessary to make a buffer design for the coupling part to ensure that the slight movement of the connecting part will not affect the stability of the transmission, and the entire charging process is not limited to short-distance closed waters, and is not too affected by environmental factors. The device needs to have a matching charging process and a relatively stable and systematic replenishment monitoring sequence, which can judge whether replenishment is needed in various situations. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the title of the invention of this application to avoid blurring the purpose of this section, the abstract of the specification and the title of the invention, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the above and / or existing technologies in the prior art, the charging methods for electric ships are also relatively limited. The most common charging pile charging has many rigid conditions, solar charging and wind charging are affected by environmental factors, and the operation and maintenance costs are high. If charging during shipping is adopted, the propeller structure coupling device of the electric ship mostly uses a non-rigid coupling to avoid excessive force on the propeller shaft in the water. Charging during shipping requires the kinetic energy of the propeller to provide basic energy conversion, so it is necessary to make a buffer design for the coupling part to ensure that the slight movement of the connecting part will not affect the transmission stability. The present invention is proposed.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0043] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Example 1

[0045] Reference Figure 1~Figure 4 The present embodiment provides a moored charging device for a ship and a method for replenishing energy thereof, including a running component 100, which is a carrier for generating kinetic energy and energy conversion vector points, and includes a power box 101, which is a transmission generating part directly connected to the paddle part, one side of the power box 101 is rotatably connected to the propeller 102, and the kinetic energy of the propeller 102 is connected here and enters the power box 101 to generate transmission, and the other side of the power box 101 is rotatably connected to the guide plate 103, and the guide plate 103 is provided with some The existence of the guide hole makes the fluid vortex power generated by the propeller 102 greater, which helps to make the propeller 102 more efficient in power generation during operation. A magnetic field source 104 is provided on the top of the entire power box 101. The magnetic field source 104 is composed of two symmetrically arranged electrode plates, which can form a strong magnetic field. A conductive plate 105 is rotatably connected inside the magnetic field source 104. The conductive plate 105 can be regarded as a conductor in the magnetic field source 104. The conductor cuts the magnetic field to form an electric current, thereby completing the process of converting kinetic energy into electrical energy.

[0046] Furthermore, the transmission component 200, that is, the related components used to complete the kinetic energy conversion, most of the related components are located inside the power box 101, including a main shaft 201 placed inside the power box 101, the main shaft 201 is coaxially connected to the impeller 102, the guide plate 103, and the flexible coupling tooth 202, the two kinetic energy points are placed at both ends of the main shaft 201, and both are outside the power box 101, and the flexible coupling tooth 202 is a part of the non-rigid coupling, and the outer shell of the flexible coupling tooth 202 is fixedly connected with a buffer plate 202a, the buffer plate 202a is an abbreviation of a component as a whole, and its entire structure is responsible for reducing the vibration and shaking caused by external forces through active connection with the hydraulic component 203.

[0047] Example 2

[0048] Reference Figure 1~Figure 4 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: the flexible coupling teeth 202 on both sides are meshed with a toothed longitudinal shaft 204 through a side gear, and the toothed longitudinal shaft 204 is used to transmit the rotation of the horizontally rotating main shaft 201 to the horizontal rotation in the vertical direction, and the toothed longitudinal shaft 204 rotates with the rotation of the main shaft 201. The end of the toothed longitudinal shaft 204 is fixedly connected with a conductive plate 105, which can be understood as a conductor that cuts magnetic flux lines. The circumference is arranged at the end of the toothed longitudinal shaft 204, and each conductive plate 105 has a multi-layer hollow design. The efficiency of generating current is increased by increasing or decreasing the cross-sectional area of ​​the conductor cutting the magnetic flux lines in the magnetic field.

[0049] Furthermore, a main port 203a is provided in the middle of the hydraulic component 203, and auxiliary ports 203b are provided on both sides of the main port 203a. The main port 203a and the auxiliary port 203b are the only two openings of the entire hydraulic component 203, and the rest of the places are sealed. A large amount of hydraulic oil is filled inside the hydraulic component 203. When an object presses down at the main port 203a, thereby squeezing the hydraulic oil to apply pressure to the space of the auxiliary port 203b, if a slidable object is also blocked at the auxiliary port 203b, the object at the auxiliary port 203b will move outwards. When the internal hydraulic oil is in a balanced state, a certain air pressure is applied to the hydraulic component 203, which will form a situation where the objects at the main port 203a and the auxiliary port 203b block the movement directions are opposite.

[0050] A pressure shifting piece 202a-1 is provided in the middle of the buffer plate 202a. The pressure shifting piece 202a-1 is a sheet metal structure that acts as a sliding column, and its role is to be a blocking object in the main opening 203a. Vertical plates 202a-2 are fixedly connected on both sides of the buffer plate 202a. A pressure rod 202a-3 is fixedly connected on the inner side of the vertical plate 202a-2. The pressure rod 202a-3 is made of hard rubber, which has a strong effect of buffering external forces and will not cause damage to related metal parts.

[0051] Example 3

[0052] Reference Figure 1~Figure 4 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the main port 203a is slidably connected with the pressure-shifting member 202a-1, and the secondary port 203b is slidably connected with the limiting member 203b-1. The limiting member 203b-1 and the pressure-shifting member 202a-1 form the above-mentioned situation that the objects at the blocking point move in opposite directions. The limiting member 203b-1 is provided with a blocking member 203b-2, and the blocking member 203b-2 is a rectangular hollow ring, and the blocking member 203b-2 is sleeved on the outer periphery of the vertical plate 202a-2 and the pressure-receiving rod 202a-3, resulting in that when the limiting member 203b-1 and the pressure-shifting member 202a-1 move in opposite directions, the pressure-receiving rod 202a-3 will be blocked by the blocking member 203b-2.

[0053] Furthermore, that is to say, when the ship needs to dock and charge, the process of dropping anchor and stopping the hull will definitely cause the hull to shake, and the external force applied to the flexible coupling gear 202 at this time is likely to cause large-scale wear of the internal transmission structure or even fall off. At this time, the buffer between the blocking member 203b-2 and the pressure rod 202a-3 can effectively reduce the damage caused by this part of the external force.

[0054] In detail, a rubber layer 203b-3 is provided on the inner side of the blocking member 203b-2, and the pressure rod 202a-3 can contact the rubber layer 203b-3. This part of the rubber layer 203b-3 is the hard rubber part mentioned above, and the other parts remain hard materials, which can further ensure the degree of external force reduction.

[0055] Furthermore, a magnetic sensing element 204a is sleeved on the toothed longitudinal shaft 204, and the magnetic sensing element 204a can judge the current remaining power SOC of the hull through the change of magnetic force and time. T The outer shell of the flexible coupling tooth 202 is provided with a support rod 202b, and the support rod 202b is used to ensure that the flexible coupling tooth 202, which may shake in the horizontal direction, has a stable connection with the inner wall of the power box 101 to prevent it from getting out of the way. A slider 202b-1 is provided at the end of the support rod 202b, and a slide rail 101a is provided at the bottom of the inner wall of the power box 101. The slider 202b-1 is slidably connected to the slide rail 101a to ensure that the movement of the entire flexible coupling tooth 202 will not deviate from the main shaft 201.

[0056] Example 4

[0057] Reference Figure 1 to Figure 6 , which is the fourth embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: the entire charging device, to realize the charging process, is to go through a series of judgment mechanisms to achieve the result, and this action needs to collect and obtain the operating parameters and equipment status of the current ship system, and through step-by-step judgment, to detect whether the ship is currently moored or not;

[0058] In the first step, the power transmission module 300 is powered to electrically connect the main shaft 201 to the generator;

[0059] The second step is to detect the charge state of the ship's battery pack and the propeller blade speed. The charge state determines whether the charging process needs to be started, and the propeller blade speed determines whether it is currently in the charging state;

[0060] The rotation of the blades generates kinetic energy to drive the generator to operate. The operation of the generator causes the propeller 102 to rotate, thereby driving the conductive plate 105 to cut the magnetic flux lines in the magnetic field source 104, generating an induced voltage to charge the ship's battery pack. During the process, the magnetic induction element 204a monitors the charge state of the ship's battery pack.

[0061] The operating parameters include: the current speed of the propeller blade N, in r / min, the minimum speed N required for the ship to start sailing X 、Ship effective propulsion power P E ;

[0062] The device status includes: battery capacity C, battery state of charge (i.e. remaining power SOC) T , anchor status.

[0063] Example 5

[0064] Reference Figure 1 to Figure 6 , which is the fifth embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: if the anchor sinks, and the effective propulsion power P of the ship E =0, i.e., the ship is judged to be in a moored state, the power transmission module is started, the main shaft 201 and the generator are electrically connected, and energy charging is prepared;

[0065] If the anchor sinks and the ship's effective propulsion power P E ≠0, that is, the ship is judged to be in the waiting state, the power transmission module is turned off and the current propulsion power of the ship is reduced until P E =0, then turn on charging;

[0066] If the anchor does not sink and the effective propulsion power of the ship is P E ≠0, that is, the ship is judged to be in a sailing state, the power transmission module is turned off, and charging is not turned on.

[0067] Furthermore, the anchor state is only a basis for judging whether to start the power transmission module 300, and the entire charging process needs further judgment before it can continue.

[0068] If the current remaining power SOC of the ship is detected T If it is lower than 80%, the propeller blade speed is tested to determine whether the subsequent charging is successful;

[0069] If the current remaining power SOC of the ship is detected T Equal to 80%, continue to detect the remaining battery power SOC T Used to monitor the charging status;

[0070] After entering the charging state, the ship's battery pack is continuously charged, the blades rotate to cut the magnetic flux lines at the conductive plate 105, and kinetic energy is generated to drive the generator to operate. The induced voltage generated by the operation of the generator is amplified instantly through the step-up transformer, and the AC and DC states of the current are changed through the frequency converter. The rectifier adjusts the current state in the same way to avoid excessive or insufficient current, which affects the judgment result. Then, the switch K1 is combined to charge the ship's battery pack;

[0071] When the control room monitors the battery charge SOC of the ship T ≥95% of the rated capacity, which meets the power requirements for long-term battery life. At this time, disconnect K1 and stop charging.

[0072] The entire device is driven by a special coupling and the idea of ​​converting the propeller rotation into induced current, forming a relatively complete ship mooring charging device assembly and charging method.
