Embodiment Construction

[0036] 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.

[0037] like figure 1 As shown, an anti-pollution anemometer includes a flow guide assembly and a wind pressure detection assembly, and the flow guide assembly includes an air duct cavity 3 composed of an upper drainage surface 1 and a lower drainage surface 2 parallel to each other;

[0038] 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 with a pressure sensor 4, and the pressure sensor 4 ...

Abstract

The invention relates to an anti-pollution anemometer, which comprises a flow diversion assembly and a wind pressure detection assembly. Cavity, the closed cavity is located in the center of the lower drainage surface, the upper part of the closed cavity is spherical, and a pressure sensor is arranged on the circular bottom of the closed cavity; the closed cavity is filled with gas; it is set between the upper drainage surface and the lower drainage surface There is an annular filter screen; the anemometer also includes a casing, the casing includes a truncated cone-shaped upper casing arranged on the top of the upper drainage surface and a lower casing arranged on the lower part of the drainage surface, the lower casing includes an air guiding ring and a supporting part, and the closed cavity is fixed on On the support part, the air guide ring is fixedly connected to the support part through several connecting rods, and an annular sewage discharge cavity with openings at both ends is arranged between the air guide ring and the support part; between the bottom of the upper shell and the upper part of the air guide ring There is an annular air guide cavity.

Description

technical field [0001] The invention relates to an anti-pollution 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; [...
