The seawater-proof external driving device comprises a left gland, a right gland, a left end cover, a right end cover, an ejector rod and a shell. The left end cover and the right end cover are fixedly connected to the left end and the right end of the shell respectively; the rod-shaped part of the ejector rod sequentially penetrates through the left end cover and the right end cover, and the cylindrical part is located between the outer surface of the left end cover and the inner surface of the shell. The ejector rod and the end cover are sealed through a stuffing box and a Glyd ring, and the left gland and the right gland are used for compressing the stuffing box; a second oil cavity is formed between the left end cover and the inner surface of the cylindrical part, and a first oil cavity is formed among the right end cover, the outer surface of the cylindrical part and the shell; the ejector rod does linear telescopic motion relative to the shell under the action of the pressure difference between the first oil cavity and the second oil cavity. The invention further discloses an anti-fouling mechanism, an in-place feedback structure and an in-place buffering mechanism. According to the invention, long-term stable driving in an outboard seawater environment can be realized.
本发明公开了一种防海水外置式驱动装置,包括左压盖、右压盖、左端盖、右端盖、顶杆和壳体;左端盖和右端盖分别固定连接于壳体的左端和右端;顶杆的杆状部分依次穿过左端盖和右端盖,筒状部分位于左端盖外表面和壳体内表面之间;顶杆与端盖之间通过填料函以及格来圈进行密封,左压盖和右压盖用于压紧填料函;左端盖与筒状部分内表面之间形成第二油腔,右端盖、筒状部分外表面、壳体之间形成第一油腔;顶杆在第一油腔和第二油腔的压差作用下进行相对于壳体的直线伸缩运动。本发明还进一步公开了防污机构、到位反馈结构和到位缓冲机构。本发明能够实现在舷外海水环境中的长期稳定驱动。
