Exhibits and Introduction of Zhengzhou Science and Technology Museum

Zhengzhou Science and Technology Museum exhibits: electric, magnetic, optical and mechanical energy conversion wheels; Planetarium; The magical universe; Large flower building loom; Archimedean spiral.

1, electric, magnetic, optical and mechanical energy conversion wheel

All circuits, windings and electromagnets in the exhibition wheel have no obvious noise, and the support is stable and reliable. The support of the wheel is connected by transparent plexiglass strips, which clearly shows that the wheel is not driven by a motor. At the same time, it can be observed that magnetic steel and electromagnet are buried in the runner.

2. Planetarium

The Digital Sky Pavilion, built with international advanced technology, can enjoy the vast cosmic starry sky and immerse yourself in the profound cosmic galaxies to learn astronomical knowledge. At the same time, with the help of advanced interactive technology, we can realize virtual interaction with starry sky and stars and experience the mystery of exploring the universe.

3. The magical universe

With the aim of "exploring the mysteries of the universe and touching space technology", the exhibition area stimulates children's interest in exploring the universe and initially establishes a scientific view of the universe and nature. Including robotech, my satellite, flying in the sky, spacecraft docking and other interactive facilities.

4. Dahua Building Loom

Jacquard is the highest achievement of ancient weaving in China. This jacquard uses heald jacquard to weave brocade. The most difficult thing to master in jacquard technology is to reproduce the expected pattern on the fabric.

Flower calligraphy refers to making thousands of warp yarns rise and fall alternately up and down regularly according to the designed pattern, and dozens of weft yarns are arranged horizontally, so as to make a whole set of pattern memory devices. Once the flowers are knotted, they can be woven on the machine.

5. archimedean spiral

Archimedean spiral is all spirals in the form of (polar equation) r=aθ. The distance of each arm of this spiral is always equal to 2 π a. In order to solve the problem of irrigating the land with water. Archimedes invented the cylindrical spiral water lifter, which was later called "Archimedes spiral".
