[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1-4 The illustrated suspension bracket for installing an acid- and alkali-resistant fan comprises a suspension mechanism and an adjustment mechanism connected to a fan body 5 .

[0026] Among them, regarding the suspension mechanism, specifically, the suspension mechanism includes a base 1, support legs 2 and a suspension seat 3. The suspension seat 3 is fixed to the upper end of the base 1 through the support legs 2. The suspension seat 3 is arc-shaped, and the fan body 5 is rotatably installed on the upper end of the suspension seat 3. Specifically, a limiting slide groove 301 is provided on the inner side of the arc of the suspension seat 3 along its arc direction, and a limiting slider 12 that is slidably adapted to the limiting slide groove 301 is integrated at the arc side end of the fan body 5, so that the fan body 5 can rotate along the suspension seat 3, thereby adjusting its air outlet direction.

[0027] Among them, regarding the adjustment mechanism, specifically, the adjustment mechanism includes a second motor 8, a driving pulley 9, a transmission belt 10 and a driven pulley 11. The second motor 8 is installed at the upper end of the base 1, and the driving pulley 9 is coaxially fixed with the output shaft of the second motor 8. The driven pulley 11 rotates on the outside of the fan shaft 6 on the fan body 5 and is fixed to the outer wall of the fan body 5. The transmission belt 10 is connected between the driving pulley 9 and the driven pulley 11.

[0028] When the air outlet direction of the fan body 5 needs to be adjusted, the fan body 5 can be rotated along the suspension seat 3 by using the second motor 8 in conjunction with the active pulley 9, the transmission belt 10 and the driven pulley 11, thereby flexibly adjusting its air outlet direction and reducing its installation limitations.

[0029] In order to avoid excessive shaking of the fan body 5 during operation caused by the setting of the above-mentioned adjustment mechanism and suspension mechanism, a locking knob 13 is threaded from bottom to top through the bottom end of the suspension seat 3 and is abutted against the outer wall of the fan body 5. When the locking knob 13 is tightened, the fan body 5 and the suspension seat 3 can be stably fixed relative to each other to ensure stable operation of the fan body 5.

[0030] Furthermore, two limit seats 15 are fixed to the bottom end of the suspension seat 3, and the two limit seats 15 are respectively located on both sides of the locking knob 13, and the two limit seats 15 are provided with limit slots 1501 for the limit plug 14 to slide through. When the locking knob 13 is tightened, the upper end surface of the limit plug 14 fits with the bottom end of the locking knob 13, which can effectively prevent the vibration generated during the operation of the fan body 5 from causing the locking knob 13 to loosen.

[0031] In addition, a motor bracket 4 for installing the first motor 7 for driving the fan body 5 is fixed to the upper end of one side of the base 1, and a protective cover 17 is fixed to the upper end of one side of the base 1. The protective cover 17 covers the outside of the adjustment mechanism and the transmission component 16 connected between the first motor 7 and the fan body 5, wherein the transmission component 16 is a conventional belt drive structure, and its end away from the first motor 7 is fixedly connected to the fan shaft 6.

[0032] It should be further explained that the structures in this solution are all made of conventional corrosion-resistant materials to meet the requirements of use in corrosive environments.

[0033] The working principle of the present utility model is as follows: when it is necessary to adjust the air outlet direction of the fan body 5, the operator can manually pull the limit plug 14 to release the limiting effect of the limit plug 14 on the locking knob 13, and then loosen the locking knob 13. Thereafter, the second motor 8 is used to drive the active pulley 9 to rotate, and the active pulley 9 rotates with the driven pulley 11 through the transmission belt 10. The driven pulley 11 can drive the fan body 5 to rotate along the suspension seat 3 to adjust its air outlet direction; after the adjustment is completed, the second motor 8 is stopped, the locking knob 13 is manually tightened, and the limit plug 14 is slid so that the limit plug 14 fits with the bottom end of the locking knob 13 to prevent the vibration generated during the operation of the fan body 5 from causing the locking knob 13 to loosen.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
