A marine hospital bed with wave compensation function and wave compensation method

Abstract

The invention relates to a marine medical bed with a wave compensation function. The marine medical bed comprises an upper platform, a lower platform and a servo cylinder set; the upper platform and the lower platform are parallel to each other; the lower platform is fixedly connected to a deck of a hull; a bed body is fixedly connected directly above the upper platform; and six servo cylinders are sequentially connected between the upper platform and the lower platform in the circumferential direction. Movement of the medical bed in six degrees of freedom of can be completely compensated in real time while rolling, pitching, swaying, surging, heaving and front-back swinging of the hull are compensated in real time, and a safe and stable recuperation space is provided for the injured underthe harsh sea conditions in the swing state; and according to a compensating platform, two central servo cylinders are vertically installed, four servo cylinders are obliquely arranged, thus, high-precision compensation of six degrees of freedom of the hull can be achieved, and the marine medical bed has the characteristics of high stability and carrying capacity, wide compensation range and thelike.

Description

technical field [0001] The invention relates to the technical field of ship wave compensation, in particular to a ship hospital bed with wave compensation function and a wave compensation method. Background technique [0002] The marine hospital bed is fixedly connected with the hull, and it is a place for the sick and wounded on board to recuperate. The marine hospital bed is required to be safe and stable. Due to the influence of wind and waves, ships operating at sea will shake irregularly with the waves, seriously affecting the recuperation of the wounded and sick on board. Therefore, appropriate measures must be taken to compensate for the waves of the hospital bed, so that the wounded and sick can get the best recuperation. [0003] The existing marine medical beds with wave compensation function are mainly divided into two types of wave compensation: one is the passive wave compensation platform, which mainly uses a spring damping system to compensate the sway and he...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a marine hospital bed with wave compensation function, which can solve the problem that the general marine hospital bed has low precision, has serious hysteresis, and cannot satisfy wave compensation on multiple degrees of freedom
