Description

Technical Field

[0002] Although traditional steel cooling towers are now popular, the installation process of steel cooling tower protection frames is relatively complicated due to structural reasons. Many components need to be welded on site, the installation efficiency is too low, and the installation cost is high. The cooling tower fan needs to be protected during operation, so it is necessary to install a protective net. A cooling tower protection net structure disclosed by searching application number CN202322417640.X records that it includes a fan frame, and the front and rear ends of the fan frame are both detachably provided with T-beams, and a motor frame is provided on the left side of the fan frame. The motor frame and the corresponding T-beam are detachably provided, and the right side of the fan frame and the two T-beams are detachably provided. There is a first protective net, and the left and right sides of the T-beam are removably provided with a second protective net. Through assembly, it is more convenient to install than the conventional welded protective frame, and it also has a stronger load-bearing capacity. At the same time, it can protect the fan blades and the inside of the cooling tower to prevent larger debris from falling into the cooling tower and causing damage to the blades and the inside of the cooling tower. However, the above description still has the following defects in actual use: after the cooling tower fan guard net is installed, there is a lack of a structure for cleaning itself. Over time, debris is easily accumulated on its surface, and it is not easy to observe the working status of the fan. Therefore, it is necessary to design a practical cooling tower fan guard net with a foreign matter cleaning structure. Utility Model Content
