The invention discloses a bevel gear differential-motion human eye movement imitating mechanism. The bevel gear differential-motion human eye movement imitating mechanism comprises a left eyeball movement mechanism, a right eyeball movement mechanism and an eyelid movement mechanism. As for each eyeball movement mechanism, two central bevel gear, a bevel planet gear and a tie rod constitute a differential gear train, each bevel planet gear is in rigid connection with each eyeball, independent rotation of the two central bevel gears is achieved through motors, the independent rotation is combined into rotation of two degrees of freedom of the bevel planet gears, and therefore the eyeballs can rotate with the two degrees of freedom in the vertical direction and the horizontal direction. Two eyelids are in rigid connection with each other through a rotary shaft and a synchronous belt wheel, the other belt wheel is in rigid connection with one motor, the two belt wheels are in transmission with each other through a synchronous belt, and opening and closing of the eyelids can be achieved through rotation of the motors. The bevel gear differential-motion human eye movement imitating mechanism is compact in structure, small in occupied space, and flexible, accurate and reliable in movement, the left eyeball and the right eyeball are independent from each other, and the two eyeballs can move in the same direction and in the different directions.

The invention discloses a stereo garage capable of quickly parking and taking bikes in batches. The stereo garage capable of quickly parking and taking the bikes in batches includes structural frameswhich are arranged at two sides to form a stereo garage framework, a plurality of bike-carrying frames are sequentially, hierarchically and horizontally piled up from the bottom to the top between thestructural frames, the other side of the interior of the stereo garage is provided with three-level telescopic forks of which the two sides are matched with the structural frames to rise and fall andcan further extend outward or shrink inward, a plurality of parking space groove shelves which are used for fixing the bikes are arranged above the bike-carrying frames side by side, and the front ends of the parking space groove shelves are provided with sensors which face to the interior of the parking space shelves. Compared with the prior art, the stereo garage capable of quickly parking andtaking the bikes in batches has the advantages of simple structure, convenient and rapid use and high application efficiency, can save land area due to a stereo structure; and the three-level telescopic forks have the advantages of compact structures, accurate running, reliable application and the like.

The invention relates to an automatic heavy-duty penetrometer capable of vertical detection, which belongs to the technical field of construction survey. Including the base plate, the base plate is provided with a bracket, and a penetrating mechanism is arranged vertically through the base plate, and the top of the penetrating mechanism is connected with a lifting mechanism arranged vertically, and the lifting mechanism is set on the bracket; The bottom is matched with the top of the arc-shaped transition frame; a level is provided on the support, and the level is used to measure the verticality of the support. The invention utilizes the free fall of the piercing hammer to vertically accelerate the falling to detect the ground, and measures the verticality through the horizontal ruler, the positioning is accurate, the bracket ensures the verticality, avoids irregular manual operation, does not need manual force, saves time and effort, and the detection process is more standardized. High detection efficiency and high detection accuracy.
