Embodiment

[0044] figure 1 and figure 2The anti-freezing ultrasonic wind sensor shown in this embodiment includes: a base, a main control board 9 connected to an external power supply is arranged inside; a probe base 5 is fixedly connected to the base 8, and the upper surface of the probe base 5 is provided with a pillar 51, the number is 3, used to support the reflective disc 3, at least one of the pillars 51 is a hollow structure, used as a wiring channel; the reflective disc 3 is supported by a top cover 1, and the lower end of the top cover 1 is provided with a square concave a slot for accommodating the temperature sensor module;

[0045] The ohmic element 2 includes an upper ohmic element 21 and a bottom ohmic element 22. Both the upper ohmic element 21 and the bottom ohmic element 22 are composed of a sheet-shaped ohmic heating element 2b and an insulating material 2a coated on the outside of the ohmic heating element 2b. The device 2b leads out the connection terminals through...

Abstract

The invention provides an anti-freezing ultrasonic wind sensor which comprises a base, a probe seat, a reflective disc and an Ohm element. A master control panel connected with a power source is arranged in the base, the probe seat is fixedly connected to the base, and a strut is arranged on the upper surface of the probe seat and used for supporting the reflective disc. A top cover is supported on the reflective disc. The master control panel is used for supplying power to the Ohm element, and the Ohm element comprises an upper-layer Ohm element body and a bottom-layer Ohm element body. The upper-layer Ohm element body is bent and laid in top clearance space formed by the top cover and the reflective disc, and the bottom-layer Ohm element body is bent and laid in lower clearance space formed by the probe seat and the base. According to a heating method of the Ohm element, the problem that in freezing rain or snow occurring in the low-temperature environment, wind and snow cover an ultrasonic probe, and consequently the sensor fails is effectively solved, meanwhile, the master control panel directly supplies power to the Ohm element, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of wind speed and wind direction measurement, in particular to an anti-freezing ultrasonic wind sensor. Background technique [0002] The ultrasonic wind speed and direction sensor is a wind speed and direction measuring instrument that uses ultrasonic pulses to measure the time or frequency (Doppler transform) difference at the receiving end to calculate wind speed and wind direction. [0003] In the low temperature environment, there will be freezing rain or snowy weather, and the wind and snow will block the ultrasonic probe and cause the sensor to fail. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to improve the problem in the prior art that the ultrasonic wind sensor is prone to failure caused by wind and snow. [0005] For this reason, the present invention provides a kind of anti-freezing ultrasonic wind sensor, it is characterized in ...
