AI Technical Summary

Technical Problem

Existing weather-specific wind direction/speed sensors are prone to icing in low-temperature environments, causing them to malfunction. Existing anti-icing solutions are costly to maintain or energy-intensive, and fail in power outage scenarios.

Method used

An inverted, short-necked, funnel-shaped anti-icing cover is designed, made of transparent polyethylene terephthalate plastic with a polytetrafluoroethylene coating on the surface. It physically blocks rainwater and frost, preventing them from contacting the gap between the sensor turntable and the base. The connection structure is fixed with epoxy resin AB glue, simplifying the installation process.

Benefits of technology

It effectively prevents rainwater and frost from contacting the gap between the turntable and the base, avoiding freezing, reducing maintenance costs, requiring no additional energy consumption, ensuring normal operation of the sensor, and is suitable for most sensor models.

Abstract

The utility model discloses an anti-icing cover for a wind direction / wind speed sensor special for meteorology, relates to the technical field of meteorological observation equipment protection, and aims to solve the problems that a gap between a rotating disc and a base of the sensor is iced to cause failure of the sensor and the existing anti-icing scheme has defects. The anti-icing cover comprises an anti-icing cover body and a connecting structure, the body is of an inverted short-neck funnel structure, the radial size of the body covers a rotating disc and a base, the body is made of a PET transparent plastic material, the outer surface of the body is coated with a polytetrafluoroethylene coating of 0.05-0.1 mm, and the polytetrafluoroethylene coating is used for reducing the adhesive force of frost on the outer surface of the anti-icing cover body. The influence of frost accumulation on turntable rotation and data accuracy is avoided; the connecting structure fixes the body to the outer wall of the rotating disc through epoxy resin AB glue, a gap is reserved between the body and the base after installation, and the size of the gap is controlled within the range of 5-10 mm. Rain and snow water is prevented from permeating into gaps through physical shielding, extra energy consumption is not needed, the structure is simple, installation is convenient, adaptability is high, normal operation of the sensor in low-temperature rain and snow weather can be guaranteed, and continuous and accurate meteorological data are guaranteed.
