Abstract

The invention relates to a wind pressure anemometer, which comprises a flow diversion assembly and a wind pressure detection assembly. The closed cavity is located in the center of the lower drainage surface. The upper part of the closed cavity is spherical. The spherical surface of the closed cavity is made of soft film. A pressure sensor is installed on the circular bottom of the closed cavity. The pressure sensor includes a circular The pressure sensing surface; the closed cavity is filled with gas, and the spherical soft film of the closed cavity is supported by the aforementioned gas; a number of air deflectors are arranged in a circular array between the upper drainage surface and the lower drainage surface, and the axis of the air deflector is located at In the diameter direction of the closed cavity, the plane where the air guide plate is located is perpendicular to the pressure sensing surface.

Description

technical field [0001] The invention relates to a wind pressure anemometer, which belongs to the field of meteorology. Background technique [0002] In a wind power generation system, an anemometer is a weight monitoring device that senses wind force, and it is an important tool for realizing the normal operation of wind power generation equipment; currently used wind farm anemometers have a relatively high failure rate. [0003] The main reasons include: [0004] 1. Thunderstorms cause damage to the wind vane and anemometer; [0005] 2. The wind measuring equipment has been operated in the supermarket environment for a long time, and the service life is shortened; [0006] 3. The wiring is not tightly bound, and the windy weather causes the wiring to be interrupted; [0007] 4. The protection level of the anemometer is not high, and the anti-fouling ability of the sealing ring is poor. It will enter into a car and cause failure, or even lock the wind speed sensor; [00...
