The structure of century clock

This century clock is made of all metal. The century clock is 40m high, with a diameter of 14.6m, a base area of 74.4m and a weight of 170 tons. It is divided into three parts: minute plate, swing frame and base, all made of metal. The pendulum swings up and down, and the sun and the moon compete for glory. Surrounded by clocks and plates, guarded by stars, the combination of Chinese and western, and the unity of heaven and man. The integration of classical and modern means the continuation of time and space, and time waits for no one.

The clock plate is surrounded by 12 constellation relief, and the pictures are all created according to the most original story. Aries is placed at the top of 12, because sheep represents auspiciousness in China; Put Libra at 6 o'clock at the bottom, because scales represent fairness. All these reflect the idea of integrating foreign culture and local culture in arrangement.

The quartz clock plate covers an area of 156 square meters. On the inner ring with a diameter of about 8m, the disc core and pointer are hollowed out, and a bronze relief with a diameter of 2.6m 12 is embedded between the outer ring and the inner ring with a pattern of 12 constellation. On the side of the dial is a huge pendulum, with the sun above and the moon below. The pendulum is S-shaped, based on the shape of the Taiji dividing line, which means that Yin and Yang alternate and end to end. The heavy forged copper base is covered with large and small gears, chains and huge screws. Rivets set off the ancient jiefang bridge, simple and elegant, telling people that China's modern industry started here. This century clock is an artistic stereo clock with the largest diameter and weight available at present. Looking around, time and space, classicism and modernity, strength and beauty, man and nature are fully integrated here, inspiring people's endless reverie and imagination.

The century clock is 40 meters high and the weight of the metal part is 180 tons. The diameter of each side of the clock is 14m and the area is about 154m 2. The 12 cast copper reliefs with a diameter of 2.6m and a weight of about 1t are 12 constellations respectively. The disk core and clock hands are hollow flowers, which look simple and generous. The heavy forged copper base is covered with large and small gears, chains and huge steel screws and rivets, which set off an interest in ancient jiefang bridge and tell people that China's modern industry started here. The dial of the clock is European style, and the Roman numerals and the central skeleton of the dial are made of stainless steel. The skeleton is inlaid with a high-grade Jakli transparent cover with a thickness of 8 mm. Roman numerals are hollowed out and inlaid. Roman numerals have an outer diameter of 8 meters, an inner diameter of 5 meters and a center dial with an outer diameter of 5 meters. The dial is inlaid with the words "Tianjin" and "2000". In the dial with a diameter of 5 meters, it will glow at night. The hour hand and minute hand are cut by stainless steel laser, and the total length of the minute hand is about 4 meters. The total weight of the hour hand and the minute hand is 180 kg. More than 30 gears are all made of steel and the outside is forged with brass. Gears represent the passage of time, the change of the century, the end of the industrialization era in the 20th century, and the operation of 2 1 century to the high-tech era. There is a huge steel long rod shape on the side of the clock plate, with a total height of 34 meters and a total weight of about 10 ton. The sun is hanging above and the moon is hanging below. The long pole is in the shape of "S", which is based on the shape of Taiji dividing line. It means that yin and yang alternate, and the first and last are born. The sun's rays and the moon's halo rotate at a constant speed of 3 revolutions per minute, which means that Tianjin is the gateway to China and embodies a small universe. Coupled with the operation of the clock, it gives people a sense of movement and strong vitality, and improves the solidified sculpture into a dynamic sculpture. The shells of the sun and the moon are all made of stainless steel. The surface of the sun is covered with pure gold foil, the surface of the moon is covered with pure silver foil, and the satellites next to the moon are also covered with pure gold foil. The column is made of red copper, with a length of 18m, a width of 6m and a weight of 40t. The platform used to support clocks and computer rooms is also made of steel.

In order to set off the Millennium clock more brilliantly, eight starry rotating lights (emitting four colors of red, yellow, green and blue respectively), three spotlights (white light) and 16 crystal lights (72 bulbs each) were erected around the Millennium clock.

In order to satisfy the authenticity and noiseless of the sound effect of the big clock, four groups of high and low outdoor speakers are installed at the terminal of the big clock platform, and the total power exceeds 2 kW, so that the volume is fully adjustable and the sound quality is ensured. The first time every day, the music of "Dongfanghong" rings, and the world-specific bell is used for each time.

Luminous at night is another feature of the century clock. In the design, internal lighting is used to make the dial part clearly visible at night, and external lighting makes the whole bright. The main controller provides an automatic switch signal, which automatically turns on and off the lights according to the length of nights in different seasons. At the same time, the lighting system also provides power switch signals to the two wheels on the swing bar, so that the periphery of the "sun" on the swing bar shines at night, and the "moon" at the lower end of the swing bar also shines.
