TECHNICAL FIELD

[0002] With the growing global demand for renewable energy, marine photovoltaic as a clean and efficient power generation method has received widespread attention. Marine photovoltaic power stations are usually located in coastal or offshore areas, where the environment is complex and changeable, including strong seawater corrosion, large waves, frequent tidal changes and other factors. Therefore, for electrical equipment in marine photovoltaic power stations, such as transformers, circuit breakers, etc., the safety design is crucial. These devices may use a large amount of insulating oil during operation, and if an accidental leak occurs, not only will it cause serious pollution to the marine ecological environment, but also may cause a fire, threatening the safe and stable operation of the power station.
[0003] Traditional accident oil pools are mostly made of concrete structures, which have certain anti-leakage ability, but have problems such as heavy weight, long construction period, poor corrosion resistance, etc. Especially in marine environments, long-term exposure to salt spray and humid conditions can easily lead to structural aging and performance degradation. In addition, the design of traditional oil pools in terms of fire prevention is often insufficient, and once a fire occurs, it is difficult to effectively stop the spread of the fire, increasing the difficulty and cost of accident handling.
[0004] In recent years, fiber reinforced composites (FRP) have been widely used in marine engineering due to their lightweight, high strength, corrosion resistance, and ease of molding. However, the fire resistance of FRP materials is relatively weak, which limits its use in applications that require strict fire protection requirements. In order to overcome this limitation and provide a more secure and reliable solution, it is necessary to develop a new type of accident oil pool structure that can fully utilize the advantages of FRP materials and effectively deal with potential fire risks.

In addition, the mounting holes on the base allow the inlet pipe and the outlet pipe to pass through smoothly, without affecting the airtightness of the whole system.
[0019] As the preferred of the utility model, the dredging hole is provided with three, and each dredging hole is communicated with a sediment and slag removal area, a static oil removal area and a secondary oil removal area.
