Description
技术领域Technical Field
本发明涉及风力发电技术领域，具体涉及一种用于漂浮式风电装备的海水压载系统及加载排载检修方法。The present invention relates to the technical field of wind power generation, and in particular to a seawater ballast system for floating wind power equipment and a loading and unloading maintenance method.
背景技术Background Art
目前用于漂浮式风电装备领域的海水压载系统主要有以下两种方式：At present, there are two main types of seawater ballast systems used in floating wind power equipment:
舱底进水海水压载系统。舱底进水海水压载系统主要由海底阀箱、压载水泵、阀门、压载水管路、空气管路、压载水舱等组成，该系统海底阀箱布置于浮式基础底部，压载水泵从海底阀箱取水，输送至各个压载水舱，对浮式平台进行加载。在配合管路和阀门的开闭，利用压载水泵将压载水舱的海水通过舱底排水口排出，从而实现对浮式平台的排载。该系统存在的主要缺点包括：（1）海底阀箱和排水口存在被海生物堵塞的问题。虽然漂浮式风电装备设计采用永久压载系统，在装备就位安装进行压载后，漂浮式海上风电装备运行期间不再进行加载和排载工作，但根据规范要求，每5年需要对压载水舱进行检修，因此需要进行排载和加载工作。（2）进水阀损坏维修困难的问题。与海底阀箱相连的进水阀在漂浮式风电装备25年寿命周期内存在锈蚀损坏、密封圈老化等风险，一旦进水阀出现损坏，将导致舱底进水，并且现场维修、更换阀门的工作困难，如现场无法维修漂浮式风电装备只能返坞维修，维持代价较大。Bilge water intake seawater ballast system. The bilge water intake seawater ballast system mainly consists of a seabed valve box, ballast water pumps, valves, ballast water pipelines, air pipelines, ballast water tanks, etc. The seabed valve box of this system is arranged at the bottom of the floating foundation. The ballast water pump draws water from the seabed valve box and transports it to each ballast water tank to load the floating platform. In coordination with the opening and closing of the pipelines and valves, the ballast water pump is used to discharge the seawater in the ballast water tank through the bilge drain port, thereby realizing the discharge of the floating platform. The main disadvantages of this system include: (1) The seabed valve box and the drain port are blocked by marine organisms. Although the floating wind power equipment is designed with a permanent ballast system, after the equipment is installed in place for ballasting, the floating offshore wind power equipment will no longer be loaded and discharged during operation. However, according to the specifications, the ballast water tank needs to be inspected every 5 years, so discharge and loading work is required. (2) The problem of difficulty in repairing damaged inlet valves. The water inlet valve connected to the seabed valve box is at risk of rust damage and sealing ring aging during the 25-year life cycle of the floating wind turbine. Once the water inlet valve is damaged, water will enter the bilge, and on-site repair and valve replacement will be difficult. If the floating wind turbine cannot be repaired on-site, it can only be returned to the dock for repair, which has a high maintenance cost.
舷外进水海水压载系统。舷外进水海水压载系统加载和排载分别采用两套独立系统，加载系统由潜水泵、压载水管路、空气管路、阀门、压载水舱等组成，漂浮式风电装备进行海水加载时，通过潜水泵从舷外取水，越过浮式基础甲板向浮式基础内部压载水舱进行海水加载。排载系统同样由潜水泵、压载水管路、阀门等组成，但潜水泵布置于浮式基础最低处压载水舱内部。该系统存在的主要缺点包括：（1）由于采用海水加载和排载两套系统，管路系统复杂，因此该系统设计制造成本相对较高。（2）压载水舱内潜水泵维修困难。Overboard seawater ballast system. The overboard seawater ballast system uses two independent systems for loading and discharging. The loading system consists of a submersible pump, ballast water pipeline, air pipeline, valve, ballast water tank, etc. When the floating wind power equipment is loaded with seawater, water is taken from the overboard through a submersible pump and loaded into the ballast water tank inside the floating foundation over the floating foundation deck. The discharging system also consists of a submersible pump, ballast water pipeline, valve, etc., but the submersible pump is arranged inside the ballast water tank at the lowest point of the floating foundation. The main disadvantages of this system include: (1) Due to the use of two systems for seawater loading and discharging, the piping system is complex, so the design and manufacturing cost of the system is relatively high. (2) The submersible pump in the ballast water tank is difficult to repair.
因此需要一种漂浮式风电装备海水压载系统，既能满足海水加载、排载要求，又能避免检修、运维的困难，还需降低设计制造成本。Therefore, a seawater ballast system for floating wind power equipment is needed, which can not only meet the requirements of seawater loading and discharge, but also avoid the difficulties of inspection and maintenance, and reduce the design and manufacturing costs.
发明内容Summary of the invention
有鉴于此，本发明要解决的问题是提供一种用于漂浮式风电装备的海水压载系统，该系统采用舷外取水方式进行加载，避免了海底阀箱堵塞、损坏现场维修困难等缺点；加载管路和排载管路采用同一套管路，简化了管路系统，减少管路设计制造成本；加载水泵及潜水泵出水管设计为工装，可灵活应用，降低成本；浮式平台内部设置有高位压载水舱，压载水舱检修时，无需将压载水排出浮式基础，因此检修时也无需潜水泵进行加载，快速高效。In view of this, the problem to be solved by the present invention is to provide a seawater ballast system for floating wind power equipment, which adopts an overboard water intake method for loading, avoiding the shortcomings of clogging of the seabed valve box, damage and difficulty in on-site repair; the loading pipeline and the discharge pipeline use the same set of pipelines, which simplifies the pipeline system and reduces the cost of pipeline design and manufacturing; the loading water pump and the submersible pump outlet pipe are designed as tooling, which can be flexibly applied and reduce costs; a high-level ballast water tank is arranged inside the floating platform.

When the floating wind power equipment is loaded with seawater, a submersible pump 4 is used to draw water from the outside of the floating foundation and load it into the ballast water tank 1 through the ballast system air pipe. The submersible pump 4 and the outlet pipe of the submersible pump 4 are designed as tooling, which can be used as a movable "tool" for other floating wind power equipment and required places. It can be used flexibly and can reduce the design and production cost of the entire system. When the floating wind power equipment is discharged from seawater, the ballast water pump 3 at the bottom of the bilge is used to discharge the water through the ballast air pipeline by opening and closing the valve.

After the repair is completed, it automatically flows back to the original ballast water tank 1. The system eliminates the seabed valve box and adopts the overboard water intake method for loading, avoiding the shortcomings of the seabed valve box being blocked and damaged and difficult to repair on site; the loading pipeline and the discharge pipeline use the same set of pipelines, which simplifies the pipeline system and reduces the cost of pipeline design and manufacturing; the loading submersible pump 4 and the outlet pipe of the submersible pump 4 are designed as tooling, which can be flexibly used and reduce costs; the floating platform is provided with a high-level ballast water tank 2 inside. When the ballast water tank 1 is repaired, there is no need to discharge the ballast water from the floating foundation, so there is no need for the submersible pump 4 to load during the repair, which is fast and efficient.
