Description

Technical Field

[0002] Acoustic radar is a device that uses the principle of radar to emit sound waves and receive the echoes scattered back by the sound waves to measure the echo intensity and the distance of the target object. As an effective means of measuring wind in wind farms, acoustic radar has the advantages of high safety, simple maintenance and low cost. It is a ground remote sensing system, which is mainly used for wind resource assessment, micro-site selection of wind turbines and continuous monitoring of wind conditions in wind farms. It is a wind measurement device designed for wind energy applications. Wind farm acoustic radars are usually set up outdoors and unattended. In an all-weather working environment, they are easily flooded or covered by snow, dust, fallen leaves, etc. and will not work properly. Therefore, they need to be protected by protective covers.

[0003] The protective cover device is generally fixed to the sodar by welding or bolt installation. Among them, although the welding method has good firmness, it is inconvenient for subsequent disassembly and maintenance work and is not flexible enough. Although the bolt installation method is flexible, it requires the use of multiple sets of bolts and tools. The installation and disassembly are both troublesome, which makes the disassembly and assembly of the protective cover device inconvenient, and therefore urgently needs to be improved.
