Wind direction indicator

Abstract

The invention discloses a wind direction indicator which comprises circular rings, a support shaft, a shaft sleeve and a windsail, wherein the windsail is shaped as a bag and is sewn on the circular rings (1) and (2) which are respectively placed in front of and behind the windsail, the circular rings are connected together through a support rod (3) and are supported by the support shaft (5), and the support shaft (5) is arranged in the shaft sleeve (6) and is fixed relative to the shaft sleeve (6). The wind direction indicator can be used for observing the wind direction remotely and more accurately, and provides the wind direction indication for the petroleum drilling process in land and sea and the agriculture and industry production. The wind direction indicator has a simple structure and is little in rotation resistance of the windsail, thereby being flexible in rotation and timely and accurate in display of the wind direction.

Description

technical field [0001] The invention relates to a wind direction indicator for identifying wind direction. Background technique [0002] There are often marking devices for measuring wind direction on airports, ships, and oil drilling derricks, such as radars, electronic weather stations, palm-type mini weather stations, etc. They mainly measure wind speed and wind direction through electronic devices, and can only be used for local control personnel close Obtain relevant data, and then transmit relevant data information at a long distance, and the wind direction cannot be visually and visually measured at a long distance. However, the wind pockets for long-distance visual wind direction are mostly simple wind pockets. The wind bag is relatively difficult, and the rotation is not flexible, and it is often stuck, which affects the timeliness and accuracy of measuring the wind direction. Contents of the invention [0003] The object of the invention is to design a wind dire...
