The disclosure provides a sealing system applicable for an ocean power generation device, which includes at least one first seal and a water leakage protection device. The water leakage protection device is located at a side of at least one first seal away from seawater, and includes a sealed water storage tank and a drain pipe. The sealed water storage tank collects and stores seawater leaked from the at least one first seal. One end of the drain pipe is communicated with the sealed water storage tank, and the seawater stored in the sealed water storage tank is discharged through the drain pipe.

The invention provides a disperse dye color paste for waterless dyeing, which comprises, by weight, 10%-40% of disperse dye filter cakes, 2%-35% of a dispersant, 5%-20% of a dyeing auxiliary, 0.1-0.5% of a surfactant, and 20%-88% of a solvent. The disperse dye color paste for waterless dyeing of the invention has a small particle size; and after waterless dyeing, a textile does not contain cleavable carcinogenic aromatic amine azo dyes, allergenic dyes, forbidden aromatic amine or bioactive substances. The disperse dye color paste for waterless dyeing of the invention can be stably stored for 6-12 months which is beneficial to the transportation of dyes and the production management of dyeing factories. Moreover, a dyeing effect featuring a high fixation rate is realized after the disperse dye color paste for waterless dyeing is applied to textiles.
