Description

Technical Field

[0001] This utility model belongs to the field of marine structures and new energy technology, specifically relating to a multi-source marine new energy fusion mobile marine charging device. Background Technology

[0002] Deep-sea development is closely related to small underwater vehicles such as unmanned underwater robots (UUVs). UUVs are mainly divided into remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs): ROVs rely on a mother ship for operation, their operating range is limited by cables, and they are suitable for fixed-point operations; while AUVs rely on batteries, and their operating range and endurance depend on battery capacity. Most AUVs have an endurance of only a few days or even a few hours, making them unable to travel long distances and limiting their working range; their charging needs are uncertain in terms of time and space, requiring them to actively seek out charging equipment. Furthermore, the vast deep-sea areas lack power grid coverage.

[0003] Offshore solar and wind energy, as abundant clean energy sources, are seeing increasingly mature development technologies. Existing technologies include two main approaches: first, using floating wind turbines to generate electricity and transmitting it to the terrestrial power grid via submarine cables; and second, using offshore charging stations to directly store the generated electricity in battery packs onboard the charging stations, providing power to passing electric vessels. However, the construction cost of transmitting electricity via submarine cables is prohibitively high; offshore charging stations are typically fixed in designated locations and cannot be moved, or require towing by barges, lacking mobility and limiting charging coverage.

[0004] Therefore, it is necessary to design a mobile marine charging device that utilizes new marine energy sources to solve the aforementioned technical problems. Utility Model Content

This device enables energy self-sufficiency, autonomous navigation, and mobile charging in deep-sea environments, further improving the endurance and operational range of small vehicles.

[0006] A multi-source marine new energy integrated mobile marine charging device includes a small waterplane area catamaran structure, an energy storage device, and a control device.

[0007] Furthermore, a wireless power transmission device is installed below the upper hull, and the wireless power transmission device is connected to the energy storage device.

[0008] Furthermore, the vertical axis fans are symmetrically installed on the upper part of the hull, and the two vertical axis fans rotate in different directions.

[0009] Furthermore, the vertical axis fan includes a blade support and a fan base; blades are provided between the blade support and the fan base, and the blades are helical curved blades that rotate around the fan's rotation axis.

[0010] Furthermore, the connection points between the support column and the submersible and the upper hull are respectively provided with a transition zone between the support column and the submersible, and a transition zone between the support column and the upper hull.

[0011] Furthermore, the support structure adopts a variable cross-sectional area design and is shaped like an hourglass.

[0012] Furthermore, the submersible body is provided with a rubber buffer coating on its inner side, and a propeller propulsion device is installed at the tail end. The propeller propulsion device is connected to the energy storage device and the control device.

[0013] Furthermore, the control device includes a GPS module and a motion sensor module.

[0014] Furthermore, the energy storage device includes multiple sets of lithium iron phosphate batteries and a power management module.

[0015] Furthermore, the solar panel comprises a monocrystalline silicon solar panel.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings. This embodiment provides a specific implementation of a mobile marine charging device.

[0031] As shown in Figures 1-6, the support platform is a small waterplane area catamaran structure, comprising a lower hull 1, a support hull 2, and an upper hull 3. Solar panels 4 and a pair of vertical axis fans 5 are installed on the deck surface of the upper hull 3.

[0032] The submersible 1 provides buoyancy for the device and has a total length of 15.5m. The axial distance between the two torpedo-shaped submersibles is 5.8m. The support platform, namely the small waterplane area catamaran structure, has a beam of 7.4m and a depth of 3.3m, providing a certain amount of heave space for the device.

[0033] The draft of the small waterplane area catamaran structure is 1.8m, meaning the waterplane area is located at the point of minimum cross-sectional area of ​​support hull 2. By reducing the waterplane area at the draft, the wave-making resistance experienced by the offshore power generation unit can be effectively reduced.

[0034] The support body 2 adopts a variable cross-sectional area design, with each support body being hourglass-shaped. This allows the draft tonnage per centimeter of the catamaran structure to vary with the draft position, thereby increasing the heave damping of the catamaran structure and improving the wave resistance of the charging device.

[0035] The hull lines and weight distribution of the small waterplane area catamaran structure were optimized to obtain the initial stability curve. Figure 7 The initial stability height is 0.53m, and the maximum restoring arm is 2.42m at a heel angle of 38°. The stability meets the requirements of the "Technical Rules for Inspection of Small Coastal Vessels" and the "Technical Rules for Statutory Inspection of Domestic Seagoing Vessels".

[0036] There is a transition zone at the connection point between the support 2 and the submerged hull 1 and the upper hull 3, which can optimize the drag experienced by the catamaran structure during navigation; at the same time, it can reduce the stress concentration effect at the connection point.

[0037] The vertical axis fan 5 is arranged in a left-right configuration, with the two fans rotating in different directions, which can counteract the yaw torque generated when the vertical axis fan is working; compared with the single vertical axis fan, the dual vertical axis fan layout has a higher power coefficient, which can improve the wind energy utilization rate in the limited deck space.

[0038] The vertical axis fan has 3 blades, and the blade profile is NACA0018 airfoil; the blades are fixed to the blade support 11 via the fan base 12;

[0039] The blades are spiral curved, meaning they bend along the Troposkein curve, which reduces the shear stress caused by centrifugal force during operation. Each blade rotates 120° around the vertical axis 10 of the wind turbine to cover all wind directions and achieve stable torque output. The rated output power of a single wind turbine is 10kW, so the wind power generation device can provide 20kW of power generation.

[0040] 14V 670W monocrystalline silicon solar panels are arranged on the deck surface of upper hull 3, with each solar panel occupying an area of ​​2.6m². 2 A total of 41 solar panels were installed, which can generate 17.5kW of power.

[0041] The engine room and power supply room are located inside the submersible 1 and are positioned close to the midships, which can lower the center of gravity of the charging device and reduce the moment of inertia during pitching.

[0042] The energy storage device includes lithium iron phosphate battery packs and a power management module. Each battery pack provides a capacity of 5 kWh. The battery compartment can hold 300 batteries, providing a total capacity of 1,500 kWh. When generating electricity, it can store electricity from wind power and solar power devices. When sailing, it can provide power to the propulsion device and replenish power for small aircraft.

[0043] The propeller propulsion device 8 is installed at the tail of the submersible 1 and is directly driven by the internal servo motor; the five-bladed propeller, designed based on the lift line theory and the lift surface theory, can match the total resistance of the marine charging device at the design speed.

[0044] The control device is connected to the energy storage device and the rudder. It changes the speed and course by changing the rotation speed of the two rudders and the speed difference between the two rudders. The control device integrates a GPS module and a motion sensor module to obtain navigation information such as the position, course, and speed of the marine charging device, thereby realizing the function of autonomous navigation.

[0045] When the battery needs to be charged, the mobile marine charging device is controlled to navigate to a designated location to generate electricity and store it in the lithium iron phosphate battery pack; when a small vehicle needs to be recharged, the marine charging device is controlled to navigate to the target small vehicle and transmit power to it via a wireless power transmission device.

[0046] like Figure 8 As shown in Figure 9, the wireless power transmission device 13 is installed on the lower surface of the upper hull 3 and consists of an arc-shaped support, a control circuit, and a rectangular transmitting coil. The wireless power transmission device is connected to the energy storage device, and the power management module transmits electrical energy to the control circuit, thereby driving the transmitting coil to generate a magnetic field. The bottom of the small waterplane area catamaran structure is regarded as a charging dock. When the small vehicle 15 with the receiving coil installed is docked at the bottom of the catamaran and the receiving coil is aligned with the transmitting coil, the electrical energy in the energy storage device can be transmitted to the target small vehicle through the wireless power transmission device.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
