Supersonic wave wind measurement sensor pillar structure

Abstract

Provided is a supersonic wave wind measurement sensor pillar structure. The supersonic wave wind measurement sensor pillar structure comprises a cylinder, energy transducer poles, supersonic wave wind measurement energy transducers, top cover poles and a top cover. The outer side of the upper portion of the cylinder is connected with the energy transducer poles; the top portions of the energy transducer poles are provided with the measurement energy transducers; the energy transducers are each spaced at a certain distance from the cylinder; the outer side of the upper portion of the cylinder is connected with the top cover poles; the top portions of the top cover poles are connected with the top cover; the top cover is spaced at a certain distance from above the energy transducers; and the energy transducers are disposed within the covering scope of the top cover. According to the invention, the heights of the energy transducers are lifted by the energy transducer poles so that the working of the energy transducers is prevented from being affected due to sand and dust and snow accumulation around the energy transducers; and at the same time, due to the effects of the top cover, the working area of the four energy transducers are not interfered by foreign materials including leaves, paper slices and the like, and rainfall.

Description

technical field [0001] The invention belongs to the field of meteorological measuring instruments, in particular to a pillar structure of an ultrasonic wind measuring sensor. Background technique [0002] Ultrasonic wind sensors are used in the measurement of wind direction and speed, especially in meteorology, energy, environmental protection, agriculture and forestry and other places. [0003] The working principle of the ultrasonic wind sensor is: use the time difference of ultrasonic wave propagation in the downwind and headwind to calculate the wind speed component along the ultrasonic propagation direction, and measure the wind speed and direction simultaneously through the combination of ultrasonic transducers in pairs. Generally, two pairs of four ultrasonic transducers are used to form an orthogonal mode. In a pair of ultrasonic transducers, when one transmits ultrasonic waves, the other receives ultrasonic waves. [0004] There are two main ways to install the tra...

AI Technical Summary

Problems solved by technology

[0004] There are two main ways to install the transducers of the existing ultrasonic wind sensors: one is to support the probes through four poles, and the four probes are completely exposed to the air. This structure makes the work in the middle of the four transducers The area is easily affected by leaves, paper, precipitation, etc.; the other installation method is that the transducer is fixed on the top of a column, and the top cover is installed on the top through a pole. , snow, etc. are easy to accumulate on it and affect the normal operation of the transducer

Both methods have disadvantages to the measurement of the sensor
