Description

Technical Field

[0001] The utility model relates to the technical field of floating buildings, in particular to a self-sufficient energy type mobile offshore charging and battery swapping station. Background Art

[0002] Due to the vast area, unobstructed environment and no land use cost on the ocean surface, a large amount of new energy, including wind energy, solar energy and surge energy, is contained. The collection of surge energy mainly relies on a comprehensive surge energy power generation platform.

[0003] The comprehensive surge energy power generation platform is an offshore floating platform that relies on floating barrels to support a large-area steel structure platform. Multiple power generation devices extending into the sea waves are arranged on the platform, which can be used to supply power to occasions such as remote oceanic islands and reefs where it is difficult to obtain electric energy through conventional means. The power generation efficiency of the comprehensive surge energy power generation platform is quite remarkable. Taking the Nankun wave energy power generation platform as an example, it can generate 24,000 kWh of electricity per day under full load conditions.

[0004] In addition to islands and reefs, small electric ships such as new energy fishing boats and new energy cargo ships also require offshore power supply. Although these electric ships are environmentally friendly, their endurance is shorter compared to traditional fuel ships. Frequent return to port for charging not only reduces their working efficiency but also limits their range of activities. If the comprehensive surge energy power generation platform can be used to charge or swap batteries (that is, swap batteries, some electric ships choose to directly swap batteries when docking, such as Huahang New Energy 1) for these ships in the open ocean, this problem can be solved.

[0005] However, the power required for charging electric ships is much greater than the power generation of the comprehensive surge energy power generation platform. The electricity generated must be stored in advance to meet the charging needs of ships and avoid waste of the electricity generated when there are no ships to charge. This requires a large number of energy storage batteries to be configured on the comprehensive surge energy power generation platform, and these energy storage batteries also need to be easily disassembled to meet the needs of battery swapping or maintenance. This is difficult to achieve for offshore platforms because offshore platforms are significantly shaken during use, and more fasteners (such as bolts) are required than on land to prevent the energy storage batteries from being knocked. However, these fasteners make battery swapping or maintenance difficult. Summary of the Utility Model

[0006] The utility model provides a self-sufficient energy type mobile offshore charging and battery swapping station.

[0007] The technical problem to be solved is that the existing comprehensive surge energy power generation platform cannot meet the off-shore charging / battery swapping needs of electric ships.

[0008] To solve the above technical problems, the present utility model adopts the following technical solutions: A self-powered mobile offshore charging and swapping station, comprising a surge energy power generation integrated platform, a energy storage battery bin arranged on the surge energy power generation integrated platform, and a multi-purpose crane for replacing energy storage batteries or transferring charging cables to devices in need of charging;

[0009] The energy storage battery bin is a cylindrical structure arranged in the surge energy power generation integrated platform. Each energy storage battery bin includes an inner truss cylinder and an outer truss cylinder connected into one body by connecting rods. Multiple energy storage battery bins are closely assembled and fixedly connected to each other to form an energy storage unit, and the energy storage unit is fixed in a waterproof compartment;

[0010] In each energy storage battery bin, a set of energy storage batteries that are in close fit with the bin wall of the energy storage battery bin are slidably arranged in the vertical direction. Each energy storage battery is electrically connected to the surge energy power generation integrated platform and the power conversion device respectively. The top of the energy storage battery bin is provided with a movable cover for preventing rainwater from entering;

[0011] The multi-purpose crane is arranged on the periphery of the surge energy power generation integrated platform and corresponds to the energy storage unit one by one. The range swept by the crane arm of the multi-purpose crane covers each energy storage battery bin in the corresponding energy storage unit, and the crane arm extends outward beyond the outer ends of all auxiliary equipment of the surge energy power generation integrated platform.

[0012] Further, in the energy storage battery bin, the gap between the inner truss cylinder and the outer truss cylinder is denoted as a ventilation gap, and a ventilation device for blowing air into the ventilation gap is arranged in the compartment where the energy storage unit is located.

[0013] Further, the members in the inner truss cylinder include horizontally arranged ring-shaped members. The ring-shaped members are arranged at intervals in the vertical direction of the inner truss cylinder. A fixing hose for fixing the energy storage battery is sleeved on the ring-shaped member, and the fixing hose is in interference fit with the energy storage battery.

[0014] Further, a fiberglass cloth for fire prevention and preventing the battery fixing hose from jamming the energy storage battery is pasted on the inner surface of the inner truss cylinder.

[0015] Further, the cross-section of the energy storage battery bin is a regular hexagon, and the cross-section of the energy storage battery is a regular hexagon consistent with the inner truss cylinder, the inscribed circle of the cross-section of the inner truss cylinder, or a rectangle formed by removing two opposite vertices from the cross-section of the inner truss cylinder.

[0016] Further, the height of the multi-purpose crane is not less than the length of the energy storage battery.

[0017] Compared with the prior art, the self-powered mobile offshore charging and swapping station of the present utility model has the following beneficial effects:

[0018] In the utility model, a honeycomb-shaped energy storage battery compartment is arranged in the wave energy power generation integrated platform. Each energy storage battery compartment is composed of two layers of inner and outer truss tubes. The energy storage battery is clamped by the elastic truss tube, and will not fall off or hit the adjacent energy storage battery during bumps (the energy storage battery is allowed to shake, but this shaking will not cause negative effects), thereby allowing a large number of energy storage batteries to be configured in the wave energy power generation integrated platform, so that the wave energy power generation integrated platform can meet the power required for offshore charging of electric ships. At the same time, since the energy storage battery is not fixed by fasteners that need to be disassembled, it can be quickly installed and disassembled with the help of a crane, thereby meeting the maintenance and power replacement needs for electric ships.

[0019] Figure 1 This is a structural schematic diagram of a self-sufficient energy type mobile offshore charging and swapping station of the utility model;

[0020] Figure 2 It is a structural schematic diagram of the energy storage battery compartment;

[0021] In the figure, 1-surge energy power generation integrated platform, 2-energy storage battery compartment, 21-inner truss tube, 22-outer truss tube, 23-ventilation gap, 24-battery fixing hose, 3-multi-purpose crane. DETAILED DESCRIPTION

[0022] like Figure 1 As shown, a self-sufficient energy type mobile offshore charging and swapping station includes a surge energy power generation integrated platform 1, an energy storage battery compartment 2 arranged on the surge energy power generation integrated platform 1, and a multi-purpose crane 3 for replacing energy storage batteries or transferring charging cables to equipment that needs to be charged;

[0023] The surge energy power generation integrated platform 1 used in this embodiment is an offshore renewable energy integrated platform previously developed by the inventor (patent number CN202320994042.6). In addition to its power generation capability, it also has interfaces for installing various auxiliary equipment.

[0024] like Figure 2 As shown, the energy storage battery compartment 2 is a cylindrical structure arranged in the surge energy power generation integrated platform 1, and each energy storage battery compartment 2 includes an inner truss tube 21 and an outer truss tube 22 connected as a whole by a connecting rod. A plurality of energy storage battery compartments 2 are closely assembled and fixedly connected to each other to form an energy storage unit, and the energy storage unit is fixed in a waterproof cabin;

[0025] The truss tube here is a tubular structure welded by steel sections like a truss column. If the strength permits, a steel reinforcement cage can also be selected, but the steel reinforcement cage should be improved. The intersection positions of the steel bars should not be tied, but should be welded and fixed. The inner and outer truss tubes provide a space for the energy storage battery to shake without affecting the surroundings, and at the same time provide an air duct for air-cooling heat dissipation when the energy storage battery discharges at a large current, which extends the battery life to a considerable extent.

[0026] A set of energy storage batteries that are tightly fitted to the wall of the energy storage battery compartment 2 are slidably arranged vertically in each energy storage battery compartment 2. Each energy storage battery is electrically connected to the surge energy power generation integrated platform 1 and the power conversion device respectively. The top of the energy storage battery compartment 2 is provided with a movable cover for preventing rainwater from entering.

[0027] The power conversion device is connected to the charging line for charging. The energy storage battery compartments 2 here do not have to be of the same size. Several energy storage battery compartments with larger cross-sectional dimensions can be set to store container-type energy storage batteries. At the same time, when charging an electric ship, it is necessary to ensure that some energy storage batteries do not participate in discharging and are reserved after being fully charged to meet the demand for battery swapping. Generally, only the energy storage batteries with the same specifications as the power batteries of the ships that need battery swapping need to be reserved in a fully charged state.

[0028] The multi-purpose crane 3 is arranged on the outer periphery of the surge energy power generation integrated platform 1 and corresponds to the energy storage unit one by one. The range swept by the boom of the multi-purpose crane 3 covers each energy storage battery compartment 2 in the corresponding energy storage unit, and the boom extends outward beyond the outer ends of all the auxiliary equipment of the surge energy power generation integrated platform 1.

[0029] The auxiliary equipment here includes cantilevers for collecting surge energy. This is not to avoid collisions. These cantilevers allow collisions with the ship, and the kinetic energy during collisions can also be collected for power generation. The boom should extend longer than these cantilevers to ensure that the charging line can reach the ship that needs to be charged.

[0030] In the energy storage battery compartment 2, the gap between the inner truss tube 21 and the outer truss tube 22 is denoted as the ventilation gap 23, and a ventilation device for blowing air into the ventilation gap 23 is arranged in the compartment where the energy storage unit is located.

[0031] The ventilation device in this embodiment is a blower arranged on the side of the compartment where the energy storage battery is located. The blower is turned on when the energy storage battery discharges externally, and blows out horizontal air, which passes through the ventilation gap 23.

[0032] The rods in the inner truss tube 21 include horizontally arranged ring-shaped rods. The ring-shaped rods are arranged at intervals along the vertical direction of the inner truss tube 21. Fixed hoses for fixing the energy storage battery are sleeved on the ring-shaped rods, and the fixed hoses are in interference fit with the energy storage battery.

[0033] That is to say, the fixed hoses here form a ring slightly smaller than the cross-section of the energy storage battery, and the energy storage battery is clamped by these rings, so that it will not collide in the energy storage battery compartment 2. In this embodiment, the fixed hose is a common PVC hose.

[0034] The inner surface of the inner truss cylinder 21 is pasted with a fiberglass cloth for fire prevention and preventing the battery fixing hose 24 from jamming the energy storage battery.

[0035] The fiberglass cloth here is a grid cloth woven from glass fibers, which does not affect the heat dissipation of the energy storage battery. At the same time, if an accident such as spontaneous combustion of the energy storage battery occurs, it can block the spread of the flame and allow the damaged battery to be pulled out in time before it spreads to the surrounding area. At the same time, since the fiberglass cloth forms a cylinder, it avoids the corners at the bottom of the energy storage battery being jammed by the battery fixing hose 24 when the energy storage battery is put in.

[0036] The cross-section of the energy storage battery compartment 2 is a regular hexagon, and the cross-section of the energy storage battery is a regular hexagon consistent with the inner truss cylinder 21, the inscribed circle of the cross-section of the inner truss cylinder 21, or a rectangle formed by removing two opposite vertices from the cross-section of the inner truss cylinder 21.

[0037] Such an energy storage battery compartment 2 can firmly fix energy storage batteries with various cross-sections on the market.

[0038] The height of the multi-purpose crane 3 is not less than the length of the energy storage battery, so as to ensure that the energy storage battery can be smoothly pulled out.

[0039] For a self-powered mobile offshore charging and swapping station of the present utility model, its usage method is as follows:

[0040] Step 1: Use a tugboat to tow the present utility model to anchor and generate electricity in a sea area with demand, such as a fishing ground, a cargo ship route, etc.; the tugboat is preferably an electric ship, so that the power supply of the present utility model can be utilized;

[0041] Step 2: The ship with demand approaches the present utility model;

[0042] Charging: Use the multi-purpose crane 3 to transfer the charging cable to the ship that needs to be charged for charging;

[0043] Battery swapping: Use the multi-purpose crane 3 to pull out the fully charged energy storage battery and transfer it to the ship that needs battery swapping, and then retrieve the empty-energy storage battery and put it into the energy storage battery compartment 2.

[0044] The embodiments described above are only used to describe the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
