A driving assembly is provided at the top of the cooling tower 200, and a working assembly is provided on the outer wall of the cooling tower 200.

[0026] Among them, the driving assembly includes a working shaft 202. The working shaft 202 is rotatably connected to the inside of the water turbine 201 and is connected to the water wheel inside the water turbine 201. An installation frame 203 is fixedly connected to the inside of the cooling tower 200. Both sides of the inner cavity of the installation frame 203 are rotatably connected to a rotating shaft 204. The tops of both sides of the rotating shaft 204 are fixedly connected to a fan 205. First gears 206 are fixedly connected to the outer walls of both sides of the rotating shaft 204. An installation shaft 207 is rotatably connected to the inside of the installation frame 203. A second gear 208 is fixedly connected to the outer wall of the installation shaft 207. The second gear 208 meshes with the first gears 206 on both sides. A belt 209 is sleeved on the outer walls of the working shaft 202 and the installation shaft 207. A housing 210 is fixedly connected to the top of the cooling tower 200 and the top of the water turbine 201. The belt 209 is located inside the housing 210. Filter nets 212 are fixedly connected to both sides of the outer wall of the cooling tower 200. A switch door 213 is hinged to the front side of the cooling tower 200. The water turbine 201 works to make the water wheel inside it rotate, thereby making the working shaft 202 rotate. In cooperation with the belt 209, the installation shaft 207 rotates as the working shaft 202 rotates, thereby making the second gear 208 rotate. Through the meshing of the second gear 208 with the first gears 206 on both sides, the fans 205 at the tops of the rotating shafts 204 on both sides rotate, so that the fans 205 inside the cooling tower 200 can work through the work of the water turbine 201, thus eliminating the need to use an electric motor to provide power to the fans 205.

[0027] Pulley wheels are rotatably connected to both sides inside the belt 209, and the pulley wheels on both sides are respectively fixedly connected to the outer walls of the installation shaft 207 and the working shaft 202, so that the belt 209 can work more stably.

[0028] Ventilation nets 211 are fixedly connected to both the upper and lower sides of the installation frame 203, enabling the air flow to be discharged from the inside of the installation frame 203 more smoothly.

[0029] The working components include a water inlet pipe 300 which is fixedly connected to the left side wall of the cooling tower 200. A first water pump 301 is fixedly installed on the outer wall of the water inlet pipe 300. A second water pump 302 is fixedly connected to the rear side of the cooling tower 200. A connecting pipe 303 is fixedly connected to the top of the second water pump 302. The connecting pipe 303 is connected to the water turbine 201.

The conveying pipe 305 is connected to the water inlet pipe 300. A cooling component is arranged inside the cooling tower 200. After connecting an external water supply device to the water inlet pipe 300 and then starting the first water pump 301, the water flow can be conveyed into the interior of the cooling tower 200. Then start the second water pump 302 to make the water flow inside the cooling tower 200 enter the interior of the water turbine 201 through the connecting pipe 303, so that the water turbine 201 can work, enabling the working shaft 202 to rotate, and enabling the driving component to work. Finally, the water flow re-enters the interior of the water inlet pipe 300 through the conveying pipe 305 and re-enters the interior of the cooling tower 200. By controlling the regulating valve 304, the flow rate of the water flow entering the interior of the water turbine 201 is reduced, thereby being able to reduce the working speed of the water turbine 201, and thus reducing the working speed of the driving component, and being able to adjust the rotation speed of the fan 205 by controlling the regulating valve 304.

[0030] A fixing sleeve 306 is fixedly connected to the top of the base 100. The water inlet pipe 300 is fixedly connected inside the fixing sleeve 306, so that the water inlet pipe 300 can work more stably.

An electromagnetic valve 406 is fixedly installed on the outer wall of the outlet pipe 405. The water flow enters the interior of the water inlet pipe 300 through the first water pump 301 and is conveyed into the interior of the shunt pipe 400, so that the two sprayers 403 spray the water flow. Then the falling water flow passes through the two radiating pipes 401 and the two cooling fillers 402, and the water flow will fall to the bottom of the inner cavity of the cooling tower 200. Finally, the remaining water is discharged through the outlet pipe 405 by controlling the electromagnetic valve 406.

[0033] Working principle: It works through the water turbine 201 to make the water wheel inside rotate, thereby making the working shaft 202 rotate. In cooperation with the belt 209, the mounting shaft 207 rotates as the working shaft 202 rotates, thereby making the second gear 208 rotate. Through the meshing of the second gear 208 with the first gears 206 on both sides, the fans 205 at the tops of the rotating shafts 204 on both sides rotate, so that the fans 205 inside the cooling tower 200 can work through the operation of the water turbine 201, thus eliminating the need to use an electric motor to supply power to the fans 205. After connecting the external water supply equipment to the water inlet pipe 300 and then starting the first water pump 301, the water flow can be transported into the cooling tower 200. Then, start the second water pump 302 to make the water flow inside the cooling tower 200 enter the water turbine 201 through the connecting pipe 303, so that the water turbine 201 can work, thereby making the working shaft 202 rotate, and then making the drive assembly work. Finally, the water flow re-enters the water inlet pipe 300 through the delivery pipe 305 and re-enters the cooling tower 200. By controlling the regulating valve 304, the flow rate of the water flow entering the water turbine 201 is reduced, so that the working speed of the water turbine 201 can be reduced, and then the working speed of the drive assembly can be reduced, so that the rotation speed of the fans 205 can be adjusted by controlling the regulating valve 304. The water flow enters the water inlet pipe 300 through the first water pump 301 and is transported into the flow dividing pipe 400, so that the spray heads 403 on both sides spray the water flow, so that the falling water flow passes through the heat dissipation pipes 401 and the cooling fillers 402 on both sides. The water flow will fall to the bottom of the inner cavity of the cooling tower 200, and finally the remaining water is discharged through the water outlet pipe 405 by controlling the solenoid valve 406.
