What is the use of Yuntai in photography?

Pan-tilt is the supporting equipment for installing fixed cameras, which can be divided into fixed and electric pan-tilt. Fixed pan/tilt is suitable for occasions with small monitoring range. After the camera is installed on the fixed pan/tilt, the horizontal and pitching angles of the camera can be adjusted, and the adjustment mechanism can only be locked after reaching the best working posture. ?

The electric pan-tilt is suitable for large-area scanning and monitoring, which can expand the monitoring range of the camera. The high-speed attitude of the electric pan-tilt is realized by two executive motors, which receive the signals from the controller for accurate operation and positioning. Under the action of the control signal, the camera on the tripod head can not only automatically scan the monitoring area, but also track the monitored object under the control of the personnel on duty in the monitoring center.

summary

Yuntai is widely used, and various special industries also have certain demand for Yuntai products. In its country of invention, the Soviet Union was widely used in photographic propaganda films. Due to the particularity of the use environment, Yuntai products are required to have special protective performance to adapt to the field environment. Common types are underwater type, high temperature type, low temperature type, anti-corrosion type and explosion-proof type. Special Yuntai has strict requirements on the materials used, protection levels and protection methods, and must comply with the corresponding industry-specific standards. Among them, the explosion-proof pan-tilt is the most prominent.

Brief introduction of explosion-proof equipment:

Many industrial sectors, such as petroleum, chemical industry, coal and national defense, often leak or overflow all kinds of flammable and explosive gases, liquids, dust and fibers in the various processes of production, processing, transportation and storage. When this substance is mixed with air, it may become an explosive mixture. When the concentration of the mixture reaches the explosive concentration range, once a fire source appears, it will cause serious accidents such as explosion and fire. At present, various types of explosion-proof electrical equipment have been developed, such as flame-proof, intrinsically safe, increased safety, positive pressure, oil-filled, sand-filled, spark-free, etc.

Examples of combustible gas, steam grade and temperature groups are as follows. For those not listed in other tables, please refer to Appendix A of GB3836. 1 Explosion-proof equipment used in coal mines are all Class I equipment, while other explosion-proof equipment used in factories are Class II equipment. According to the maximum test safety gap or minimum ignition current ratio suitable for explosive gas mixture, Class II equipment is divided into three grades: A, B and C.. The value T6 of T 1 is the maximum allowable surface temperature of the equipment, that is, T 1-450℃, T2-300℃, T3-200℃, T4- 135℃, T5- 100℃ and T6-85℃.
