Embodiment Construction

[0019] The present invention will be further described below with reference to the description of the drawings and specific embodiments, but it is not intended to limit the scope of protection thereof.

[0020] see figure 1 , a dynamic sealing device for a telescopic full-turn steering oar of the present invention, including a lifting shaft 1, a fastening mechanism 2, a gland 3, a lip seal ring 4, an O-ring 5, a lubrication system 6, an oil ring 7. Packing 8, stuffing box 9, mounting bolt 10, base 11, O-ring 12, guide sleeve 13, stop valve 14, detection oil circuit alarm 15, lubricating grease 16, oil tank 17, sea water A, cabin B. The stuffing box 9 is installed on the base 11 through the mounting bolts 10, and an O-ring 12 is installed between the stuffing box 9 and the base 11. The stuffing box 9 is a hollow tube, and the bottom is a stepped hole. A guide sleeve 13 is placed, and the inner hole of the guide sleeve 13 is equipped with a lifting shaft assembly 1, and a packi...

Abstract

The invention relates to a seawater-proof movable sealing device of ocean engineering equipment, in particular to a movable sealing device for a telescopic full-revolving rudder paddle, which is used on an ocean engineering boat and an ocean platform. The sealing performance of the telescopic full-revolving rudder paddle is ensured through four measures of a guide sleeve guide and filth clearing protection measure, a packing sealing measure, a lip-type sealing ring sealing measure and a lubrication and leakage check measure, through the efficient lubrication and the leakage check measure, the movable sealing device of the telescopic full-revolving rudder paddle is in an efficient controllable state in seawater, the work safety of the sealing device is improved, and the service life of the telescopic full-revolving rudder paddle is prolonged by more than 50 percent.

Description

technical field [0001] The invention relates to a seawater-proof dynamic sealing device for marine engineering equipment, in particular to a dynamic sealing device for telescopic full-rotation rudder propellers on marine engineering ships and offshore platforms. Background technique [0002] As humans march into the deep sea, the dynamic positioning system (dynamic positioning system) composed of retractable full-turn rudder and propeller devices is more and more widely used in the ocean due to its characteristics of free lifting, 360° rotation, and flexible operation. Engineering equipment, such as marine research ships, semi-submersible ships, offshore platforms, offshore drilling platforms, underwater vehicles (ROV) and military ships minelaying ships, submarine motherships, etc. Therefore, dynamic positioning is the key to deep sea development One of the techniques. [0003] When dynamic positioning, the lifting shaft of the retractable full-turn rudder device extends o...
