Seabed leaked oil collecting system

Disclosed is a seabed leaked oil collecting system. The seabed leaked oil collecting system is characterized by comprising a seabed wellhead oil collecting cover, a seabed lifting pump system, an underwater emergency storage tank, an overwater separation combustion device, an anchor moored positioning system and the like. The seabed wellhead oil collecting cover is a cylinder. The seabed lifting pump system comprises a seabed conveying pump inlet valve, a seabed conveying pump and a seabed conveying pump outlet valve. The seabed conveying pump is a centrifugal pump. The underwater emergency storage tank is of a cuboid structure and comprises a storage tank power positioning module, a storage tank counter weight module, a storage tank buoyancy module, a seawater cavity, an oil gas cavity and the like. The overwater separation combustion device comprises a burner, a torch supporting frame, a water surface torch supporting foundation, an underwater separator buoyancy block, an underwater separator and the like. The underwater separator is an oil gas two-phase separator. A symmetric anchor setting mode is adopted in the anchor moored power positioning system. The seabed leaked oil collecting system can be suitable for the situation that rescue sea conditions are adverse, and wider in application range.
