Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a fan cover with protective function. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. The term "fan" generally includes ventilators, blowers, and wind turbines. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; as a wind source for wind tunnels; and in air-cushioned vehicles for inflation and propulsion.

[0003] After a period of use, existing fan covers require staff to clean the dust on their surface. Since fans are mostly installed in high areas, manual cleaning is very troublesome and dangerous.

[0004] Therefore, it is necessary to provide a new wind turbine cover with protective functions to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fan cover with protective function, which solves the problem that the surface of the existing fan cover is very troublesome and dangerous to clean manually.

[0006] The protective fan cover provided by this utility model includes a fan base, on which the fan cover is installed. A support frame is provided directly above the fan cover. The bottom of the support frame is detachably connected to the fan base by bolts. A support column is movably installed on the support frame. An arc-shaped mounting seat is fixed at the bottom of the support column. A cleaning brush is installed on the arc-shaped mounting seat and the cleaning brush is in contact with the surface of the fan cover.

[0007] In a preferred embodiment, a first bevel gear is mounted on the top of the support column, a limiting seat is mounted on the support frame, a rotating shaft is movably disposed on the limiting seat, and a second bevel gear is mounted on the rotating shaft, the second bevel gear meshing with the first bevel gear.

[0008] In a preferred embodiment, a motor is mounted on the support frame, and the output end of the motor is connected to the rotating shaft via a coupling.

[0009] In a preferred embodiment, the rotating shaft and the limiting seat are movably connected by a bearing.

[0010] In a preferred embodiment, a protective shell is mounted on the support frame, and both the first bevel gear and the second bevel gear are located inside the protective shell.

[0011] In a preferred embodiment, the hood is made of galvanized steel.

[0012] The beneficial effects of this utility model are as follows: The machine cover is made of galvanized steel, which is corrosion-resistant, high temperature-resistant, high strength, and has a good protective effect. By setting a support frame, the impact resistance is improved, and the protective effect of this fan cover is further improved.

[0013] When it is necessary to clean the surface of the machine cover, start the motor to drive the rotating shaft to rotate. Under the transmission action of the first bevel gear and the second bevel gear, the support column will be driven to rotate. When the support column rotates, it will drive the arc-shaped mounting base and the cleaning brush above it to rotate as well. The cleaning brush can clean the surface of the machine cover.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A perspective view of the main structure of the protective fan cover provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of A shown; Figure 3 The main structural plan view of the fan cover with protective function provided by this utility model.

[0020] In the specific implementation process, such as Figures 1-3As shown, it includes a fan base 1, on which a cover 2 is installed. The cover 2 is made of galvanized steel, which is corrosion-resistant, high-temperature resistant, high-strength, and provides good protection.

[0021] A support frame 3 is installed directly above the cover 2. The bottom of the support frame 3 is detachably connected to the fan base 1 by bolts. A support column 4 is movably installed on the support frame 3. An arc-shaped mounting seat 5 is fixed at the bottom of the support column 4. A cleaning brush 6 is installed on the arc-shaped mounting seat 5. The cleaning brush 6 is in contact with the surface of the cover 2. A first bevel gear 7 is installed on the top of the support column 4. A limit seat 8 is installed on the support frame 3. A rotating shaft 9 is movably installed on the limit seat 8. The rotating shaft 9 and the limit seat 8 are movably connected by a bearing.

[0022] A second bevel gear 10 is mounted on the rotating shaft 9, and the second bevel gear 10 meshes with the first bevel gear 7. A motor 11 is mounted on the support frame 3, and the output end of the motor 11 is connected to the rotating shaft 9 through a coupling. A protective shell 12 is mounted on the support frame 3, and the first bevel gear 7 and the second bevel gear 10 are both located inside the protective shell 12, which is dustproof and waterproof, and improves their service life.

[0023] The working principle of this utility model is as follows: The cover 2 is made of galvanized steel, which is corrosion-resistant, high temperature-resistant, high strength, and has a good protective effect. By setting the support frame 3, the impact resistance is improved, and the protective effect of this fan cover is further improved.

[0024] When it is necessary to clean the surface of the machine cover 2, the motor 11 is started to drive the rotating shaft 9 to rotate. Under the transmission action of the first bevel gear 7 and the second bevel gear 10, the support column 4 will be driven to rotate.
