Antifreeze automatic insulation system for wind direction recorder
When designing the wind speed recorder, it highlights the automatic and thermostatic control functions. Taking into account outdoor use, it should also meet the requirements of safety, reliability and easy maintenance. The control system consists of temperature-controlled switches, step-down transformers, PID function temperature control instruments, solid state relays, heaters and temperature measuring elements. Its main parts include ambient temperature detection, intelligent temperature control instrumentation, solid state relays, heaters, temperature measurement platinum thermal resistance five parts, which together constitute a closed-loop temperature control system, complete the function of temperature control. The temperature control switch is adjustable around 10Â°C. It detects the ambient temperature and completes the automatic heating and heat preservation function.
Need to explain, because the weather is cold, and the wind direction recorder has small heater power (only 25W), so there is no cooling method such as water cooling or fan forced cooling, but the ambient air can be naturally cooled. For heaters that need to be installed, we recommend 24V electric heating with automatic temperature control heaters wound on the sensor, or the use of custom-made circular plate heaters, the specific power can choose about 50-100W, and then, with plastic Insulation tape can be wrapped around the package. If you choose to use electric heating automatic temperature control heating products, you can refer to the design and use instructions of domestic temperature control heating cable.
The wind direction recorder uses an automatic anti-freeze insulation control system, which can solve the freezing and freezing of the wind direction recorder and ensure the accuracy of the observation data. However, in Guanyang County where the automatic antifreeze heat preservation control system is not used, the wind direction and the wind speed sensor are frozen and frozen, causing the wind direction and wind speed data to be missed for a long time.
The bending machine is a machine capable of bending a thin plate. The structure mainly comprises a bracket, a worktable and a clamping plate. The worktable is placed on the bracket, the worktable is composed of a base and a pressure plate, and the base passes through the hinge and the clamping plate. Connected, the base is composed of a seat shell, a coil and a cover plate, and the coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by the wire, and after the power is applied, the platen is attracted to the platen, thereby achieving the clamping of the plate between the platen and the base.
