Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments, which are not intended to limit the invention:

as shown in fig. 1 and 2, a wind direction and wind speed monitoring device includes a light source 1, a phototriode 2, an optical fiber 3, a simply supported beam 4, a spring 5, a force transmission block 6, a rotating wheel 7, a first rotating shaft 8, an upper rotating disk 9, a second rotating shaft 10, a lower rotating disk 11, an optical fiber cover 12, an optical fiber cover 13, a cover plate 14, a box body 15, a rotating piece 16, a wind cup 17, a wind cup connecting screw 18, a light emitter 19, and a light receiver 20, wherein the cover plate 14 is connected with the box body 15 through screws, and a through hole is processed on the box body 15; the cover plate 14 and the box body 15 are both provided with sliding chutes; a flat key groove is processed on the first rotating shaft 8; the first rotating shaft 8 is respectively connected with the cover plate 14 and the box body 15 through bearings and penetrates through a through hole in the box body 15; the second rotating shaft 10 penetrates through the box body 15 and is connected with the box body 15 through a bearing; the upper part of the second rotating shaft 10 is connected with the upper rotary disc 9 through a screw; a plurality of light emitters 19 and light receivers 20 are uniformly distributed on the circumference of the upper turntable 9; the optical emitter 19 and the optical receiver 20 are used in a paired mode, and when the box body 15 is positioned right below the optical emitter 19, the optical receiver 20 can receive the reflected light of the optical emitter 19; the lower part of the second rotating shaft 10 is connected with the lower rotary table 11 through a screw.

The working process is as follows: when wind acts on the cover 14 and the case 15, the cover 14 and the case 15 rotate about the second rotating shaft 10 until the same direction as the wind stops rotating. The light emitter 19 is always in a light emitting state, and when the cover plate 14 and the box body 15 rotate to a certain position, the light receiver 20 at the corresponding position receives light due to the light reflection effect of the box body 15, so that the wind direction information can be monitored. Wind acts on the wind cup 17, so that the wind cup 17 drives the first rotating shaft 8 to rotate, and the rotating speed of the wind cup 17 is in direct proportion to the wind speed. The first rotating shaft 8 drives the rotating part 16 to rotate through a flat key, then drives the rotating wheel 7 to rotate, and when the rotating wheel 7 contacts the force transmission block 6, the force transmission block 6 can be driven to move. At this time, the slide of the force transmission block 6 slides in the slide grooves of the cover plate 14 and the case 15. The force transfer block 6 realizes reciprocating horizontal motion under the action of the spring 5 and drives the simply supported beam 4 to do reciprocating bending motion. So that the bending curvature of the optical fiber 3 adhered on the simply supported beam 4 is periodically changed, and further the output light intensity of the optical fiber 3 is periodically changed. The phototriode 2 receives the light intensity signal output by the optical fiber 3, and the periodic frequency of the light signal is detected, so that the purpose of measuring the wind speed is achieved.
