Embodiment Construction

[0039] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0040] Such as figure 1 As shown, the present invention is a wind pressure anemometer with high environmental tolerance, including a flow guide assembly and a wind pressure detection assembly. The flow guide assembly includes an upper drainage surface 1 and a lower drainage surface 2 parallel to each other. The air duct cavity 3;

[0041] The wind pressure detection assembly includes a closed cavity 6, the closed cavity 6 is located at the center of the lower drainage surface 2, the upper part of the closed cavity 6 is spherical, and the spherical surface of the closed cavity 6 is made of soft film. The circular bottom of the closed chamber 6 is provided wit...

Abstract

The invention relates to a wind pressure anemometer with high environmental tolerance, which includes a flow guide assembly, a wind pressure detection assembly and a voltage stabilizing assembly. cavity; the wind pressure detection component includes a closed cavity, which 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, and the circular bottom of the closed cavity is provided with a pressure Sensor; a number of wind deflectors are arranged in a circular array between the upper drainage surface and the lower drainage surface, the axis of the wind deflectors is located in the diameter direction of the closed cavity, and the plane where the wind deflectors are located is perpendicular to the pressure sensing surface; the voltage stabilizing component includes Pressure controller and air pump, the limit bearing pressure of the spherical surface of the closed chamber is A, and the measured wind pressure is B. When (A‑B) / A is less than 10%, the pressure controller starts the air pump to pressurize the closed chamber , when (A‑B) / A is greater than 10%, stop pressurizing.

Description

technical field [0001] The invention relates to a wind pressure anemometer with high environmental tolerance, 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 ...
