Embodiment

[0026] Referring to Figures 1 - 3 , which is the first embodiment of the present utility model, a dust-proof device for a fiberglass cooling tower is provided. This dust-proof device for a fiberglass cooling tower includes a cooling tower 1, a plurality of groups of support frames 2 are fixedly connected to the bottom of the cooling tower 1, a protection unit 3 is arranged at the ventilation opening of the cooling tower 1, and a cleaning unit 4 is arranged at the bottom of the cooling tower 1; the protection unit 3 includes two groups of first semi-circular arcs 31 and two groups of second semi-circular arcs 32, the two groups of first semi-circular arcs 31 and the second semi-circular arcs 32 are clamped and fixed, two groups of first sliding groups 33 and a plurality of groups of second sliding groups 35 are arranged on the surface of the first semi-circular arc 31, and a first motor 34 is arranged at the top of one of the first sliding groups 33.

[0027] The first sliding group 33 includes a first slider 331. One of the first sliders 331 is fixedly connected to the side surfaces of the first semi-circular arc 31 and the second semi-circular arc 32, and the other first slider 331 is slidably connected to the side surfaces of the first semi-circular arc 31 and the second semi-circular arc 32.

A first motor 34 is arranged on one side of the top of one of the first connecting rods 332, and the output end of the first motor 34 is fixedly connected to one side of the top of the first connecting rod 332. The second sliding group 35 includes a second slider 351. A second connecting rod 352 and a third connecting rod 353 are arranged on the top of the second slider 351. The second connecting rod 352 and the third connecting rod 353 are symmetrically arranged. One of the second connecting rods 352 close to the first slider 331 is rotatably connected to the first connecting rod 332, and the adjacent third connecting rods 353 and the second connecting rods 352 are rotatably connected. One of the first connecting rods 332 is rotatably connected to the third connecting rod 353 close to the first slider 331. A plurality of groups of shading nets 38 are fixedly connected to the bottoms of the second slider 351 and the first slider 331.
