Problems solved by technology

The existence of this situation makes those who use the fan feel worried, and seriously affects the work
When the fan blade is used for a long time or there are quality problems in the processing of the fan blade, the possibility of the fan blade breaking is greatly increased. Once the fan blade breaks, it will endanger the health of the staff and even their lives.

Embodiment 1

[0022] A manufacturing method of an industrial large fan with fan blade protection measures:

[0023] Step 1. Lay a single metal wire in the blade mold, pour the blade into the blade mold to form an aluminum alloy profile, and trim the model after pouring to prevent the metal wire from being exposed;

[0024] Step 2: Use metal wires to fill in the metal wires in the direction of the fixing grooves of the upper blade and the lower blade, and use the locking device to fix the metal wires, and fix the upper blade and the lower blade horizontally and vertically, and the fan blade is completed.

Embodiment 2

[0026] A manufacturing method of an industrial large fan with fan blade protection measures:

[0027] Step 1. Pour the blade into the blade mold to form an aluminum alloy profile, and reserve the tension wire insertion port;

[0028] Step 2. Insert the tension wire into the reserved opening, and fix it on both sides of the blade through the locking device;

[0029] Step 3: Use metal wires to fill in the metal wires in the direction of the fixing grooves of the upper blade and the lower blade, and use the locking device to fix the metal wires, fix the upper blade and the lower blade horizontally and vertically, and the fan blade is completed.

Abstract

The invention provides an industrial large fan with fan protection measures. A tensioning wire is embedded in each blade, and the tensioning wires are continuously distributed in each whole blade, so that all parts of each blade are connected together, and a fixing net covers the outside of each blade. Due to the protection measure, the injury to people caused by unexpected falling of the blades can be prevented, and in addition, the appearance quality and the use of the large fan cannot be influenced.

Description

technical field [0001] The invention relates to a large industrial fan with protection measures for fan blades. In particular, it relates to a fan blade with wire mesh products such as embedded and outer wrapped metal wires. Background technique [0002] Because the comfort brought by industrial large fans is unmatched by other fans, its powerful air stirring ability makes the indoor air in large spaces flow continuously, which can not only improve the stuffy feeling, but also improve comfort, so many large places use it. to industrial large fans. Currently known protective measures for large industrial fans are generally designed to prevent the fan from falling off in the axial direction, and there is no anti-breakage and fall-off prevention measure for the fan blades. The existence of this situation makes those who use the fan feel worried, and seriously affect the work. When the fan blade is used for a long time or there are quality problems in the processing of the fan...
