Description

Technical Field

[0001] The utility model specifically relates to the technical field of high-seal lateral propulsion, in particular to a high-seal marine lateral propulsion device. Background Art

[0002] The lateral thruster is a ship propeller installed on the side of the ship to obtain good maneuverability. Some marine engineering ships, such as cable-laying ships and drilling and exploration ships, are equipped with lateral thrusters. The lateral force generated by the lateral thruster during turning can reduce the turning radius. In this way, cable-laying ships and drilling ships will not yaw when sailing at low speeds.

[0003] When installing the lateral propulsion device, the lateral propulsion propeller needs to cooperate effectively with the rotating shaft. The lateral propulsion propeller is exposed to water, but the rotating shaft needs to be sealed to prevent water from entering the hull when the rotating shaft is rotating and causing damage to the driving equipment.

[0004] After searching, Chinese patent application number CN202222898462.2 discloses a ship stern tube sealing device; including a rear bushing, which is a tubular structure, a flange is arranged at one end of the rear bushing, a sand-proof cover, a rear sealing cover, a plurality of sealing seats, and a sealing body are mounted on the outer ring of the rear bushing, and the spacing ring, the sand-proof cover, the rear sealing cover, and the plurality of sealing seats are all arranged to be composed of two C-shaped components, the sand-proof cover, the rear sealing cover, and the plurality of rear sealing seats are connected to the sealing body by bolts, the sealing body is connected to the spacing ring, the sealing body and the anti-net cover are both annular structures, and the extension of the anti-net cover is located on the outer ring of the sand-proof cover;

[0005] The structure in the above patent cooperates with the rear bushing through the cooperation of the sealing ring I, the sealing ring II and the sealing ring III during sealing. Thus, when the shaft inside the rear bushing rotates, a large friction is generated, which is not conducive to the long-term use of the shaft and may also cause damage to the inner surface of the rear bushing.

[0006] In view of the above situation, we provide a highly sealed marine lateral propulsion device. In this device, the rotating shaft passes through the sealing assembly. Through the cooperation between the cylinder and the clamping plate, the inner wall inclined surface of the clamping plate and the rotating shaft are effectively gradually fitted together during sealing. After the cooperation is completed, the end of the cylinder is inserted into the reserved gap between the placement table and the placement groove, which effectively ensures that the connecting assembly and the matching seat are tightly matched. After the connecting assembly and the matching seat are matched, the ear plate on the edge of the cylinder is matched with the countersunk hole on the seat body through a screw to achieve the overall connection and sealing of the mounting seat, the matching seat and the sealing assembly with the connecting assembly.
