Description

Technical Field

[0001] This utility model relates to an industrial ceiling fan balancing and anti-fall device. Background Technology

[0002] Large industrial ceiling fans are high-efficiency ventilation devices that generate massive airflow. They are widely used in large spaces such as industrial plants, logistics warehouses, stadiums, and livestock farms, solving the problem of insufficient air circulation in these locations using smaller ventilation equipment. Existing industrial ceiling fans, in order to provide such large airflow, have very large blade diameters. This results in drawbacks such as long individual blade length, heavy weight, and poor overall balance. To ensure the safety of the blades during long-term operation, reduce the load on the motor, and minimize the safety hazards caused by irreversible failures of the rotating parts (such as the falling of rotating components), it is necessary to address these issues.

[0003] Therefore, there is an urgent need to improve the balance of large industrial ceiling fans during rotation. Utility Model Content

[0004] In order to overcome the problems of the existing technology, this utility model provides an industrial ceiling fan balancing and anti-fall device.

[0005] This utility model provides the following technical solution:

[0006] An industrial ceiling fan balancing and anti-fall device is provided. The fan blades are 1.5-4m long. The ceiling fan motor is fixed to the bottom of the roof steel structure beam or concrete beam by a suspension rod. A pair of balancing lugs are provided on the upper part of the ceiling fan motor shaft. One end of the balancing steel cable is connected to the balancing lug and the other end is connected to the roof beam. The angle between the balancing steel cable and the suspension rod is 45-60°.

[0007] Furthermore, the balancing lugs are one or more pairs.

[0008] Furthermore, the motor cover is equipped with a reinforcing plate and a bowl-shaped support plate, and the fan blades are connected to the fan blade mounting strip.

[0009] Furthermore, the upper innermost ring of the bowl-shaped support plate is an inner safety ring, and the fan blade mounting strip is connected above the bowl-shaped support plate.

[0010] Furthermore, an outer safety ring is provided at the upper part of the first hole at the end of the fan blade mounting hole.

[0011] Furthermore, the reinforcing plate, the bowl-shaped bearing plate, the inner safety ring, the outer safety ring, and the fan blade mounting strip are all fixed by high-strength bolts and self-locking nuts.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] (1) This utility model can improve the balance of large industrial ceiling fans when they rotate, reduce the safety of life and property caused by irreversible safety accidents caused by fans, and has high economic benefits.

[0014] (2) The anti-fall device adopted by this utility model protects the entire motor and fan rotating parts to prevent irreversible failure of the fan rotating parts (the rotating parts fall), which can effectively reduce safety hazards and help protect life and property safety.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the structural diagrams and specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0019] Example 1

[0020] This utility model provides an industrial ceiling fan balancing and anti-fall device. The fan blades are 1.5-4m long, resulting in a ceiling fan diameter of 3.0-8.5m after installation. The ceiling fan motor is fixed to the underside of a roof steel or concrete beam via a suspension rod 1. A pair of balancing lugs 3 are provided on the upper part of the ceiling fan motor shaft. One end of a balancing steel cable 2 is connected to the balancing lug, and the other end is connected to the roof beam. The angle between the balancing steel cable and the suspension rod is 45-60°. There are one or more pairs of balancing lugs, preferably two pairs. The function of the balancing steel cable is to maintain overall balance and reduce irreversible structural damage to the motor cover caused by vibration.

[0021] The motor housing 11 has a lower groove for mounting a bearing 10, which connects to the motor shaft 9. The motor cover 4 has an upper groove for mounting a bearing 12, the inner hole of which is installed on the motor shaft 9. The motor stator is mounted on the motor shaft within the cavity formed by the motor housing and the motor cover. A bowl-shaped support plate 7 is fitted inside the upper part of the motor cover. The upper innermost ring of the bowl-shaped support plate is an inner safety ring 13. The bowl-shaped support plate and the upper inner safety ring form a whole, ensuring the safety of the cover. A fan blade mounting strip connects to the top of the motor cover. The motor cover contains a bowl-shaped support plate 8 and a reinforcing plate 6. The fan blades are attached to the fan blade mounting strip 15. An outer safety ring 14 is installed at the upper part of the first hole at the end of the fan blade mounting hole. The reinforcing plate, bowl-shaped support plate, inner safety ring, outer safety ring, and fan blade mounting strip are all fixed with high-strength bolts and self-locking nuts. Other parts of the fan blade 5 are fixed with high-strength bolts and self-locking nuts to prevent the connecting nuts from falling off.

[0022] Even if the fan blades and fan blade mounting strips break accidentally due to external force during operation, the fan blades will not fall off due to the interconnection between the inner and outer safety rings and the bowl-shaped support plate.

[0023] The embodiments described above are merely illustrative of the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
