High-environmental-tolerance air pressure type anemometer

Abstract

The invention relates to a high-environmental-tolerance air pressure type anemometer. The high-environmental-tolerance air pressure type anemometer comprises a flow guide assembly, an air pressure detection assembly and a pressure stabilizing assembly. The flow guide assembly includes an air duct cavity composed of an upper drainage surface and a lower drainage surface, wherein the upper drainage surface and the lower drainage surface are parallel to each other; the air pressure detection assembly includes a closed cavity, the closed cavity is located in the center of the low drainage surface, the upper portion of the closed cavity is of a spherical surface shape, the spherical surface of the closed cavity is made of a soft film, and a pressure sensor is arranged at the round bottom of the closed cavity; a plurality of air guide plates are arranged between the upper drainage surface and the lower drainage surface in an annular array mode, the axes of the air guide plates are located in the direction of the diameter of the closed cavity, and the plane where the air guide plates are located is perpendicular to a pressure bearing surface; the pressure stabilizing assembly comprises a pressure controller and an air pump, the ultimate bearing pressure of the spherical surface of the closed cavity is A, and actually measured wind pressure is B; when (A-B) / A is smaller than 10 percent, the pressure controller starts the air pump to pressurize the closed cavity; when (A-B) / A is greater than 10 percent, pressurization is stopped.

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 ...
