[0002] The existing Chinese patent discloses a cylindrical filter screen structure of a seawater filter (authorization publication number CN219764657U). This patent includes a seawater filter body. A sleeve is arranged on the outer wall of the seawater filter body. A fixing ring is fixedly connected to the outer wall of the sleeve. A movable ring is slidably connected to the outer wall of the sleeve and below the fixing ring. A sealing housing is arranged outside the sleeve. A fixing shaft is fixedly connected to the inner wall of the sealing housing. A torsion spring is arranged on the outer wall of the fixing shaft.
