Description

Technical Field

[0001] The present invention relates to the technical field of power storage equipment, and in particular to a deep-sea floating power storage structure. Background Art

[0002] Green renewable energy has unlimited development potential. With the large-scale development of offshore wind power, it is an inevitable trend for offshore wind power to move from nearshore to deep sea. At present, deep sea wind power transmission mainly includes AC transmission, flexible DC transmission and offshore wind power hydrogen production. AC transmission is to transmit the AC power generated by offshore wind farms to land through submarine cables. However, there are problems of capacitance effect and difficulty in controlling reactive voltage compensation during long-distance transmission; flexible DC transmission is to use flexible transmission technology to convert the AC power generated by offshore wind farms into DC power for transmission. However, there are many power electronic devices in the converter of this method, which will produce large switching losses, resulting in an increase in the overall system loss, and its equipment cost and construction cost are relatively high, and the technical maturity needs to be improved.

[0003] Hydrogen production at sea consumes a lot of energy, and it also faces additional huge challenges brought by the complex chemical environment of seawater: First, seawater corrodes the electrolyzer. The composition of seawater is complex, such as dissolved ions, bacteria, impurities, etc., which corrode the electrolyzer components; second, impurities in seawater can cause catalyst deactivation. Impurities will deposit and adhere on the ion exchange membrane and catalyst surface, causing ion channels and catalytic active sites to be blocked, causing the catalyst to deactivate quickly. Third, the efficiency of seawater electrolysis is low. The concentration of hydrogen ions and hydroxide ions in seawater is very low. During the electrolysis process, the mass transfer rate is slow, making the electrolysis efficiency very low;

[0004] With the large-scale development of offshore wind power, considering factors such as resource potential and sea area land use, it is an inevitable trend for offshore wind power to move from nearshore to deep sea. Compared with nearshore wind farms, deep sea wind farms face more stringent requirements for transmission. The long-distance transmission of large-capacity offshore wind power is a technical problem that needs to be solved urgently for the development and utilization of deep sea wind power. Existing technologies such as submarine cable transmission and offshore hydrogen production face restrictive absorption problems such as long transmission distance, high cable transmission cost, and low offshore hydrogen production efficiency. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a deep-sea floating power storage structure, which utilizes "floating power storage and power exchange platform + power transport ship" to construct a new mobile consumption path of offshore wind power conversion + power storage + power exchange + power transportation + power exchange, which can effectively reduce the development cost of deep-sea wind power resources, alleviate the problem of power consumption, and open up the sea and land full-process industrial chain of containerized charging, power storage, and power exchange.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a deep-sea floating power storage structure, including a floating body, a connecting plate is fixed to the side wall of the floating body, and a single-point mooring is arranged at the position of the connecting plate, a containerized battery is arranged on the surface of the floating body, and deck cranes are distributed on the sides of the containerized battery.

[0007] Optionally, the floating body is also equipped with a living area, wherein the living area is used for staff activities.

[0008] Furthermore, the single point mooring is used for mooring to an offshore wind farm.

[0009] Furthermore, a plurality of container-type batteries are provided, and the distributed container-type batteries are stacked.

[0010] Optionally, the living area is used to provide accommodation, dining, communication, entertainment and fitness activities for the staff.

[0011] Furthermore, a helicopter platform is provided on the surface of the floating body; wherein the helicopter platform is used to ensure timely rescue and safe evacuation of the staff.

[0012] Optionally, the helicopter platform can also provide air transportation for personnel or materials.

[0013] From the above, the deep sea floating power storage structure of the present invention has the following beneficial effects:

[0014] 1. Using "floating power storage and power exchange platform + power transport ship" to build a new mobile consumption path for offshore wind power conversion + power storage + power exchange + power transportation + power exchange can effectively reduce the development cost of deep-sea wind power resources, alleviate the problem of power consumption, and open up the sea and land full-process industrial chain of containerized charging, power storage, and power exchange;

[0015] 2. In actual use, the deep-sea floating power storage and exchange platform is moored near the offshore wind farm through a single-point mooring. The electricity generated by the offshore wind turbine is connected to the deep-sea floating power storage and exchange platform through a submarine cable through a single-point mooring and charges hundreds of containerized batteries on the platform. The containerized batteries are modularly arranged on the floating body of the platform. Their size is the size of a freight container. They contain battery cabinets, refrigeration systems, junction cabinets, converter cabinets, central control cabinets and fire cabinets. The power transport ship shuttling between the dock and the deep-sea wind farm berths at the floating body of the floating power storage and exchange platform, and the fully charged containerized batteries are charged using the equipment on the platform. The deck crane is installed to lift it onto the power transport ship, and the containerized batteries to be charged on the power transport ship are lifted onto the platform for charging, thereby completing the power transfer, charging and battery replacement of the offshore wind farm. The power transport ship transports the fully charged containerized batteries to the dock and further distributes them to electric vehicles, electric ships, microgrids and other users. The deep-sea floating power storage and exchange platform is equipped with a living area to provide staff with living services such as accommodation, catering, communications, entertainment and fitness.
