Marine rudder bearing with water absorption and drainage structure

Abstract

The invention discloses a marine rudder bearing with a water absorption and drainage structure. The marine rudder bearing comprises a supporting ring base, a bottom sealing cover, a rudder stock, a sealing ring body, an annular pressing plate and a water absorption and drainage assembly. When water leaks due to the sealing performance problem between the sealing ring body and the rudderstock, leaked water can be continuously absorbed through the annular water absorption column, the weight can be increased after the annular water absorption column continuously absorbs the water, in this way, real-time monitoring is conducted through the pressure sensor, and when the pressure sensor detects that the pressure reaches a threshold value, the rudderstock is stopped from being damaged. A signal is fed back to an external controller, the external controller drives a power module, moisture absorbed in an annular water absorption column is extruded out through downward extrusion of a drainage annular plate, the extruded moisture can be discharged through a long and narrow drainage pipeline, then the drainage annular plate is reset upwards, and therefore regular water absorption and drainage are achieved. Entering water can be effectively absorbed and regularly discharged, and the phenomenon of absorption saturation of the annular water absorption column is avoided.

Description

Technical Field

[0001] The invention belongs to the field of ship rudder bearing structures, and in particular relates to a ship rudder bearing with a water absorption and drainage structure. Background Art

[0002] The rudder bearing is a general term for a bearing device fixed on the hull to support the rudder. It is used to support the weight of the rudder stock and the rudder and ensure the watertightness of the hull. The connection with the rudder bearing ensures that the rudder blade can rotate with the rudder stock so as to control the turning and driving direction of the ship. When installing the existing rudder bearing, the rudder stock is inserted into the rudder bearing, and a bottom sealing cover is arranged at the bottom of the rudder bearing to maintain the seal with the rudder stock. A sealing filler and a pressure plate are arranged inside the bottom sealing cover. The sealing filler is sealed to the rudder stock and the bottom sealing cover through the extrusion of the pressure plate, so that the sealing effect is achieved. However, due to the long-term rotation of the rudder stock, the rudder stock will rub against the sealing filler for a long time, so that the sealing filler is deformed, and then the sealing effect is reduced, so that water enters the interior and corrodes the internal parts. Although the amount of water entering is not large, a large amount of water will enter due to long-term accumulation. Therefore, it is necessary to improve the processing structure of detection, water absorption and drainage, improve the reproducibility of the structure, and improve the sealing performance.
