[0031] In the embodiment, mounting ring 6 is first installed and positioned around fan tower drum 2, so that it is in a suitable position. Then, one end of the plurality of support plates 7 is fixed on mounting ring 6, and the angle of support plate 7 is adjusted, so that, after installation of protective shell 4, the side wall of support plate 7 can be closely in abutment with the inner wall of protective shell 4.
[0032] The utility model mounting ring 6 provides a stable mounting base for support plate 7, ensuring uniform distribution and correct positioning of support plate 7 inside protective shell 4. Support plate 7 effectively transmits the external force borne by protective shell 4 to mounting ring 6 through abutment with the inner wall of protective shell 4, and then uniformly disperses to fan tower drum 2 by mounting ring 6, improving the ability of protective shell 4 to resist external force, optimizing the force transmission path, reducing local stress concentration, and being conducive to long-term stable operation of protective shell 4 and fan tower drum 2.
[0033] Further, the mounting ring 6 has a first ring frame 61 with a first sliding groove 611 and a second ring frame 62 with a second sliding groove 621, and the second ring frame 62 is hingedly arranged at one end of the first ring frame 61, and the first sliding groove 611 is in communication with the second sliding groove 621 after the rotation of the second ring frame 62, and the mounting ring 6 further comprises a plurality of sliding blocks 8, and the plurality of sliding blocks 8 are slidingly arranged in the first sliding groove 611, and a plurality of supporting plates 7 are arranged on the sliding blocks 8.
[0034] In the embodiment, the first ring frame 61 and the second ring frame 62 are preliminarily placed around the fan tower 2, and one end of the second ring frame 62 is hingedly connected with one end of the first ring frame 61.
[0035] The utility model discloses can flexibly adjust the position of supporting plate 7, has improved the versatility and adaptability of whole protection structure.
[0036] Further, the supporting plate 7 has a first connecting plate 51 and a second connecting plate 52, and one end of the first connecting plate 51 and the second connecting plate 52 is hingedly arranged on the sliding block 8, and the other end is hingedly connected with the adjacent first connecting plate 51 or second connecting plate 52.
[0037] In the embodiment, one end of the first connecting plate 51 and the second connecting plate 52 is hingedly connected on the sliding block 8, and then the other end of the adjacent first connecting plate 51 and the second connecting plate 52 is hingedly connected with each other, forming a folding type supporting structure, which props up a stable supporting frame between the inner wall of the protection shell 4 and the mounting ring 6.
[0038] The hingedly connected supporting plate 7 has good deformation adaptability.
[0039] Further, the protection shell 4 has a first half shell 41 and a second half shell 42, and the second half shell 42 is hingedly arranged on the first half shell 41.
[0040] In the embodiment, the second half shell 42 is connected to the first half shell 41 through a hinge to form a structure of the openable protective shell 4.

[0041] The half-shell structure of the utility model can facilitate the installation operation of the protective shell 4 on the fan tower 2. Compared with the integral protective shell 4, the protective shell 4 does not need to be sleeved from the top of the fan tower 2, thereby reducing the installation difficulty and the risk of damage to the fan tower 2 and the fan foundation 1 during the installation process. In particular, when the protective shell 4 is installed in the later stage after the fan has been installed, the advantages of the structure are more obvious, the installation efficiency is improved, and the utility model is convenient for popularization and application.
[0042] Further, the sealing ring 9 is arranged at one end of the protective shell 4, and the one end of the protective shell 4 abuts against the fan tower 2 through the sealing ring 9.

[0044] The sealing ring 9 further enhances the sealing performance between the protective shell 4 and the fan tower 2. Even if there is a slight unevenness on the abutting surface of the protective shell 4 and the fan tower 2 or the abutting surface is slightly displaced due to vibration during the operation of the fan, the sealing ring 9 can fill the gap by deforming elastically, prevent liquid and impurities from seeping from the abutting position, improve the sealing reliability of the overall protective structure, and better protect the fan foundation 1 and the tower connection part from erosion.
[0045] Further, the locking member 10 is arranged on the protective shell 4 and used for limiting the relative position of the first half shell 41 and the second half shell 42.
[0046] In the embodiment, after the first half shell 41 and the second half shell 42 of the protective shell 4 are closed, the locking member 10 is installed at an appropriate position, for example, a bolt nut assembly is used, the bolt is passed through the corresponding mounting holes of the first half shell 41 and the second half shell 42, and then the nut is tightened, so that the relative position of the first half shell 41 and the second half shell 42 is fixed, and the overall structural stability of the protective shell 4 is ensured.
[0047] The locking piece 10 can ensure that the protection shell 4 keeps a tightly closed state after installation, prevents the first half shell 41 and the second half shell 42 from relatively displacing due to external wind force, vibration and other factors, and thus maintains a good sealing effect of the protection shell 4 on the gap. Meanwhile, when the inside of the protection shell 4 needs to be inspected or maintained, the locking piece 10 can be conveniently disassembled, and the protection shell 4 is opened, thereby improving the use convenience and maintainability of the protection structure.
