The invention relates to a boat
deck pillar, which comprises a base, a plurality sections of supporting pipes, an oil cylinder and a pump body. The supporting pipes sleeve mutually, a sealing structure is arranged between every two supporting pipes, the supporting pipes are filled with hydraulic oil, the oil cylinder is arranged on the base, a conducting oil channel is arranged between the oil cylinder and the supporting pipes, the pump body for controlling on-off of the conducting oil channel is arranged on the conducting oil channel, a movable supporting plate is arranged at the upper end ofthe supporting
pipe on the innermost side, and a ball journal is arranged at the bottom of the movable supporting plate, a spherical holding cavity covering the ball journal is formed in the corresponding supporting
pipe, the supporting pipes are circumferentially provided with eye plates, the eye plates of multiple boat
deck pillars form a well-shaped pillar array through connecting rods, the pump body is used for controlling the
oil pressure in the supporting pipes, so as to realize ascending or descending of the supporting pipes, the pump body is used for realizing stepless adjustment of the heights of the supporting pipes, and supporting of different hulls is met; and connection among the eye plates can be used for forming the array, and through height adjustment of the supporting pipes of the corresponding positions, adaptive
hull arbitrary curved surface is achieved.
