A blade 2 is installed on the outer side of the wheel disc 1. The blade 2 is a three-dimensional flow airfoil blade, which is in an arc shape. A housing 4 is installed at the lower end of the wheel disc 1 through a motor. The housing 4 installs the blade in the high-efficiency cooling tower for use, and a mounting ring 5 is installed on the side of the housing 4. An inner groove 6 is opened on the inner wall of the wheel disc 1. The inner groove 6 is used for installing a filter screen 1002, and a filter component 10 for dust filtering is installed inside the inner groove 6. The filter component 10 includes a cleaning rod 1001 and a filter 1002, and the filter 1002 is arranged below the cleaning rod 1001. The cleaning rod 1001 is driven by a motor to clean the surface of the filter 1002 to avoid clogging of the filter 1002. The cleaning rod 1001 and the filter 1002 are distributed in parallel, and the shape of the cleaning rod 1001 is a cross. The filter 1002 allows the fan blade 2 to filter the gas contacted by the blade 2 when working in the cooling tower, thereby reducing the residual dust on the surface of the blade 2.

[0024] like Figure 2 As shown, a cleaning assembly 3 for cleaning the surface of the blade 2 is arranged on the side surface of the wheel disc 1, and the cleaning assembly 3 includes a mounting groove 301, a cleaning nozzle 302, a cover plate 303, a connecting rod 304 and a control ring 305. The cleaning nozzle 302 is installed inside the mounting groove 301, and the cleaning nozzle 302 sprays compressed gas to wash and clean the surface of the blade 2, thereby cleaning the residual dust on the surface of the blade 2, avoiding the accumulation of dust and other impurities that affect subsequent use, and reducing the number of manual cleaning times, and the mounting groove 301 is A cover plate 303 is arranged on the outside, and the cover plate 303 covers the installation groove 301 when the cleaning nozzle 302 is not in use, so as to prevent the installation groove 301 from affecting the wind flow. The upper end of the cover plate 303 is connected to a connecting rod 304, and the end of the connecting rod 304 is connected to a control ring 305. The connecting rod 304 and the control ring 305 are rotated by the rotating rod 9 driven by the motor to complete the opening and closing action. The installation groove 301 and the wheel disc 1 are an integrated structure, and the installation groove 301 and the blades 2 are distributed in a ring-shaped interval about the center point of the wheel disc 1.
