That clock turns like an electric fan.
1, the clock is a timing device.
It usually consists of a bell shell and a clock face. An electric fan is an air suction device driven by electric energy, which can suck air into the fan blades and then discharge it. The mechanism between them is completely different, so no face clock can turn so fast as an electric fan.
To understand the specific clock making principle and influencing factors, please look at the history and technical development of mechanical or electronic clock making. Detailed knowledge of these fields can give you a deeper understanding.
2, the working principle of mechanical clock
A mechanical clock is a device that uses mechanical principles to time. It usually consists of a bell shell, a clock face, a movement and a gear.
When the spring on the movement stores a certain amount of energy, it will drive the gear to rotate, thus driving the hands on the clock face to rotate. The energy stored in the clockwork is gradually released, making the pointer rotate at a certain speed. This mechanical principle makes the rotation speed of the face hand of the clock very stable, which is completely different from the working principle of the electric fan.
3. The working principle of electronic clock
Electronic clock is a device that uses electronic technology to time. It usually consists of electronic components, display panel and circuit board.
The electronic clock uses a quartz crystal oscillator to generate a stable frequency signal, which is used to time and control the movement of numbers or hands on the display panel. Unlike mechanical clocks, electronic clocks have higher timing accuracy and can display more information, such as date, time and alarm clock.
The history of clocks and watches
1. The earliest clocks and watches were based on astronomical phenomena.
Such as sundials, water clocks and hourglasses. These clocks and watches have some shortcomings, such as being influenced by weather, geography and seasons, or not accurate and stable enough.
2. The Middle Ages
Mechanical clocks and watches began to appear in Europe. They use swinging or balanced wheels to control the passage of time. These clocks were first used in churches and monasteries, and later in cities and royal families. Mechanical clocks and watches play an important role in the development of science, religion and society.
