Safe and reliable hollow shaft industrial fan with strong heat dissipation function

Abstract

The invention discloses a safe and reliable hollow shaft industrial fan with a strong heat dissipation function. The safe and reliable hollow shaft industrial fan comprises a hanging frame assembly, ahollow shaft, a motor driving part, a plurality of fan blades, an anti-di sengagement central supporting rod; the hollow shaft is fixed to the bottom end of the hanging frame assembly, an up-down through channel is formed inside the hollow shaft, the motor driving part is arranged on the periphery of the hollow shaft, the plurality of fan blades are driven by the motor driving part to rotate, andthe anti-disengagement center supporting rod penetrates through the hollow shaft; a central tray capable of supporting the motor driving part is arranged at the bottom of the anti-disengagement central supporting rod, a plurality of hanging rings are arranged on the periphery of the hanging frame assembly and stably hung on a roof through first steel wire ropes penetrating through the hanging rings, and the upper portion of the anti-disengagement central supporting rod is hung on the roof through second steel wire ropes. The safe and reliable hollow shaft industrial fan is firm and reliable in connection, high in safety performance and good in heat dissipation effect.

Description

technical field [0001] The invention belongs to the technical field of industrial fans, and in particular relates to a safe and reliable hollow-shaft industrial fan with strong heat dissipation function. Background technique [0002] Industrial ceiling fan is a common industrial machine widely used in high and large spaces such as industrial plants, logistics storage, waiting rooms, exhibition halls, gymnasiums, supermarkets, etc., as a space ventilation and personnel cooling. It can push a large amount of airflow to the ground, forming a horizontal movement of airflow layer at a certain height on the ground, thus promoting the overall air circulation. The advantage of this lies in the all-round ground coverage and the three-dimensional circulation of the air, which can achieve natural ventilation, super large Coverage area.

AI Technical Summary

Problems solved by technology

[0003] When the weather turns hot, especially in summer, the indoor working temperature of large-scale venues, especially industrial plants, is getting hotter and hotter. Traditional fans have a very limited cooling effect on high-temperature days of more than 30 degrees. It is also difficult to achieve the problem of power consumption, so industrial ceiling fans can be regarded as a feasible solution

[0004] Although the existing industrial ceiling fans have many advantages, there are still deficiencies in terms of safety, noise and motor heat dissipation. Due to the huge size of the fan blades, the length of the fan blades can reach 7.3 meters. If the ceiling fan parts, especially the motor, fall , which will cause great harm to the workers below, and because the existing industrial fans are driven by ordinary asynchronous motors and reducers, this method makes a lot of noise when the ceiling fan is running. The cooling effect is poor due to the lack of a better heat dissipation structure, which will inevitably have an adverse effect on the service life of the ceiling fan.

[0005] In the prior art, the patent number is CN201920902927.2, which discloses an industrial ceiling fan. Although the steel wire rope is used as a safety means to prevent falling off, it will still fall off after falling off. Its safety performance needs to be improved, and the heat dissipation effect is not ideal.
