The fixing frame is arranged in rows at the bottom of the cooling tower rain zone, and the air diversion top plate is fastened to the top of the fixing frame to form the roof of the air distribution corridor. This design increases the air intake of the cooling tower and improves the cooling effect. At the same time, the system has a simple structure, is easy to maintain and repair, and has high practical value.

Through the setting of the rain shelter water collection tank 102 and the hydrodynamic turbine fan assembly 2, the rainwater falling through the rainwater zone falls into the rain shelter water collection tank 102 and then flows out through the water collection tank on the rain shelter water collection tank 102. The potential energy 51 of the rainwater drives the hydrodynamic turbine fan assembly 2 to rotate. The fan blades 203 draw the cold air outside the wet-cooled ventilation cooling tower body 8 along the cold air channel to the central rainwater zone of the wet-cooled ventilation cooling tower body 8, thus achieving a better central cooling effect of the wet-cooled tower.

[0037] like Figures 1-10 As shown, the rain cover assembly 1 includes a rain cover body 101 and a rain cover water collection tank 102. The rain cover body 101 and the rain cover water collection tanks 102 on both sides of the rain cover body 101 are combined into one unit. The upper part of the rain cover body 101 is provided with a number of arrays of equally spaced rain cover reinforcing ribs 103.

[0038] like Figures 1-10 As shown, the hydro-powered turbine assembly 2 includes a turbine main shaft 201, an outer shaft sleeve 202 is provided on the turbine main shaft 201, six circumferentially distributed turbine blades 203 are provided on the circumference of the outer shaft sleeve 202 and fixed with screws, a turbine blade frame 204 is provided at the head of the turbine blades 203, and several circumferentially distributed hydro-powered turbine blades 205 are provided on the outer circumference of the turbine blade frame 204 and fixed with screws.

[0039] like Figures 1-10As shown, the fan shroud assembly 3 includes a hydrodynamic fan shroud 301. Inside the hydrodynamic fan shroud 301, two symmetrically arranged fan mounting brackets 303 are fixedly connected by screws. A fan shaft fixing bracket 302 is welded onto the fan mounting bracket 303. The hydrodynamic fan shroud 301 is provided with several eye bolt mounting holes 304 for eye bolt bodies 403.

[0040] like Figures 1-10 As shown, the fan cover hanger assembly 4 includes several symmetrically arranged cantilever hanger iron parts 401, short fan cover hanger 402, and long fan cover hanger 404. The cantilever hanger iron parts 401 are fixed to the upper part of the packing layer beam 6 by means of a bracket. The cantilever hanger iron parts 401, the short fan cover hanger 402, and the long fan cover hanger 404 are all fastened to the cantilever hanger iron parts 401. The lower part of the short fan cover hanger 402 and the long fan cover hanger 404 is provided with a lifting eye screw body 403 that matches the lifting eye screw mounting hole 304.

[0041] like Figures 1-10 As shown, the fan blade frame 204 is rotatably installed inside the two fan mounting brackets 303. The fan main shaft 201 is rotatably installed on one side of the two fan shaft fixing brackets 302. Six fan blades 203 are fixedly sleeved on the outer circumferential surface of the fan main shaft 201.

[0042] like Figures 1-10 As shown, the interior of the wet and cold ventilation cooling tower body 8 has several arrays of equally spaced rainwater cold air channels 5.

[0043] like Figures 1-10 As shown, the fan shaft fixing bracket 302 has a rotating groove inside, and the fan main shaft 201 is rotatably installed inside the rotating groove.

[0045] In this embodiment, the rain shelter assembly 1 is fixedly installed at both ends of the fan cover assembly 3 with screws. After connection, it blocks rainwater and becomes the cold air channel 5 in the rainwater area. The rain shelter water collection tank 102 is installed in the rainwater area. The potential energy 51 of the rainwater collected on the rain shelter water collection tank 102 flows along the water collection tank to the water turbine blade 205, which drives the fan blade 203 on the water turbine fan assembly 2 to rotate. The cold air outside the tower is flowed by the water turbine blade 205 along the cold air channel to the central rainwater area of ​​the wet and cold ventilation cooling tower, which solves the problem that the cold air outside the tower is difficult to enter the central rainwater area of ​​the wet and cold ventilation cooling tower.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
