The invention relates to an automatically adjusted fatigue-proof support of a displayer, a tablet personal computer or a notebook computer. The support comprises a base, two groups of inequilateral shear type telescoping mechanisms, a screen bracket and a driving control device. Two circular sliding guide rods pointing towards a sphere centre O serving as the view point are arranged on the base, the two groups of inequilateral shear type telescoping mechanisms can generate curve telescoping motions, left and right swinging and radial motion with the sphere centre serving as the view point under the effect of the driving control device, screen composite motions driven by the inequilateral shear type telescoping mechanisms can be up and down, left and right, front and back, horizontal rotating and vertical rotating motions with the sphere centre O of a viewer serving as the view point, and a screen is kept horizontal constantly and the screen center vertical line is kept pointing towards the view point of the viewer constantly so as to obtain the best visual effect. The support only needs a driving controller and is low in cost and simple to control. Visual fatigue, cervical vertebra fatigue and lumbar vertebra fatigue of human bodies can be prevented by aid of the screen motions.

The invention discloses a six-degree-of-freedom water tank navigator suitable for submerged ice-breaking research. The navigator mainly includes three parts: a guide rod movement mechanism, a cam movement mechanism and a waveform monitoring mechanism, wherein the guide rod movement mechanism and the cam movement mechanism The cooperation between the two mechanisms enables the submersible to produce a six-degree-of-freedom combined motion of surge, sway, heave, roll, pitch and yaw. The waveform monitoring mechanism is used to record the bending deformation response of the ice layer excited when the submerged body moves with different combined degrees of freedom. The ice water pool test instrument provided by the present invention can flexibly adjust the motion state of the submersible in the pool according to the experimental research requirements, and then explore the ice-breaking efficiency of the submersible under different motion states, and provide data support for the submersible to break ice and discharge water.
