Description

Technical Field

[0001] The utility model relates to the field of cooling tower equipment, in particular to a protection net structure for a cooling tower fan. Background Technique

[0002] With the development of technology, the society has an increasing demand for steel structure cooling towers. Currently, steel structure cooling towers have been widely popularized. Cooling tower manufacturers mostly adopt the process of laser cutting steel plates and then bending them to produce steel structure cooling towers. At present, although traditional steel structure cooling towers have been popularized, due to structural reasons, the installation process of the protection frame of steel structure cooling towers is relatively complex. Many components need to be welded on site, resulting in too low installation efficiency and high installation costs. At the same time, the bearing capacity of the traditional protection net is insufficient. The long-term operation of the cooling tower fan is likely to deform the protection net, failing to achieve the due protection effect. In serious cases, it may cause the fan to tilt or large sundries to fall in, damaging the fan and the cooling tower. Among them, a protection net structure with the application number "CN202322417640.X" is more convenient, efficient and simple to operate than the conventional welded protection frame through assembly. It also has a strong bearing capacity and can protect the fan blades and the inside of the cooling tower, preventing larger sundries from falling into the inside of the cooling tower and damaging the fan blades and the inside of the cooling tower, affecting the operation of the cooling tower. However, there are still certain deficiencies in the use of this protection net: Since the motor frame inside the protection net is fixedly installed with the motor of the cooling tower fan, the protection net is fixed together with the motor. When performing maintenance on the top of the cooling tower later, the motor frame and the motor need to be removed, and then the protection net needs to be removed to enter the inside of the cooling tower, with cumbersome steps, thus reducing the maintenance efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a protection net structure for a cooling tower fan to solve the problem in the above background technique that since the motor frame inside the protection net is fixedly installed with the motor of the cooling tower fan, the protection net is fixed together with the motor. When performing maintenance on the top of the cooling tower later, the motor frame and the motor need to be removed, and then the protection net needs to be removed to enter the inside of the cooling tower, with cumbersome steps, thus reducing the maintenance efficiency.
