[0027] When the internal temperature of the cooling tower needs to reach a certain limit, the temperature sensor 4 transmits a signal to the signal receiver 8, and the signal receiver 8 drives the servo motor 512 to operate, and the servo motor 512 drives the connecting shaft 514 to rotate, and the connecting shaft 514 drives the fan blades 513 to rotate inside the connecting frame 3, and then the fan blades 513 discharge the high-temperature water vapor inside the water tank 2, and then the water vapor enters the baffle 501, and then the water vapor is cooled in the baffle 501. After cooling to a certain temperature, the water vapor forms water droplets attached to the baffle 501, and the water droplets flow down along the inner wall of the baffle 501, and then the water droplets enter the water holding frame 507, and then the water droplets flow downward from the leakage hole 508 into the connecting pipe 509, and then the water droplets enter the bellows 510 from the connecting pipe 509, and then the water droplets enter the water tank 2 from the fixed pipe 511 for cooling.

[0028] The effect achieved by the entire auxiliary structure 55 is that a baffle 501 is set above the connecting frame 3 and the water tank 2, and then when the fan cools the water inside the water tank 2, the water vapor and heat in the cooling tower rise, and then the water vapor and heat enter the baffle 501, and then after a long period of cooling, the water vapor is cooled to generate water droplets, and then the water droplets flow downward through the inner wall of the baffle 501, and then flow into the water holding frame 507, and finally enter the water tank 2 to cool down the inside of the cooling tower, and then be recycled.

[0029] like Figure 1 and Figure 3 As shown, a collecting structure 6 is provided at the upper end of the connecting rod 504, and the collecting structure 6 includes four fixed blocks 63, and the four fixed blocks 63 are fixedly connected to the four connecting rods 504, and the inner wall of the fixed block 63 is slidably connected with a support rod 61, and the upper end of the support rod 61 is fixedly connected with a collecting bucket 62, and the lower end of the collecting bucket 62 is fixedly connected with a connecting ring 67, and one side of the fixed block 63 is slidably connected with an insertion rod 64, and the insertion rod 64 is slidably connected to the support rod 61, and the arc surface of the insertion rod 64 is sleeved with a spring 65, and the two ends of the spring 65 are respectively fixedly connected to the insertion rod 64 and the fixed block 63, and the side where the two insertion rods 64 are close to each other is fixedly connected with a round rod 66, and the round rod 66 is a stainless steel rod.

[0030] When it is necessary to collect and utilize rainwater, pull the round rod 66 to move, the round rod 66 drives the insertion rod 64 to move, the insertion rod 64 drives the spring 65 to stretch, and then the insertion rod 64 is separated from the fixed block 63, and then the collecting bucket 62 is pulled to move, the collecting bucket 62 drives the support rod 61 to move, and then the support rod 61 is aligned with the fixed block 63, and then the support rod 61 is inserted into the fixed block 63, the insertion rod 64 is aligned with the fixed block 63 and the support rod 61, and then the round rod 66 is released, the spring 65 is contracted to drive the insertion rod 64 to be inserted into the fixed block 63 and the support rod 61 for fixation, and then in rainy weather, rainwater enters the collecting bucket 62 for collection, and then the rainwater flows down from the connecting ring 67, and then the rainwater flows from the surface of the baffle 501 into the water holding frame 507 and then into the water tank 2.

[0031] The effect achieved by the entire collecting structure 66 is that in rainy weather, the collecting bucket 62 collects rainwater. Because the temperature of rainwater is relatively low, the rainwater is collected by the collecting bucket 62 and then flows to the surface of the baffle 501.

[0034] The effect achieved by the entire adjustment structure 77 is that after collecting rainwater, the servo motor 79 is started to operate, the servo motor 79 drives the rotating shaft 76 to rotate, the rotating shaft 76 drives the auxiliary plate 77 to rotate, and then the auxiliary plate and the fixed plate 78 are staggered. After use, the auxiliary plate 77 and the fixed plate 78 are staggered, thereby controlling the water flow rate to avoid low rainwater utilization rate caused by too fast water flow rate.

[0035] The overall working principle is that when the internal temperature of the cooling tower needs to reach a certain limit, the temperature sensor 4 transmits a signal to the signal receiver 8, the signal receiver 8 drives the servo motor 512 to operate, the servo motor 512 drives the connecting shaft 514 to rotate, the connecting shaft 514 drives the fan blades 513 to rotate inside the connecting frame 3, and then the fan blades 513 discharge the high-temperature water vapor inside the water tank 2, and then the water vapor enters the baffle 501, and then the water vapor is cooled in the baffle 501. After cooling to a certain temperature, the water vapor forms water droplets attached to the baffle 501, and the water droplets flow down along the inner wall of the baffle 501, and then the water droplets enter the water holding frame 507, and then the water droplets flow downward from the leakage hole 508 into the connecting pipe 509, and then the water droplets enter the bellows 510 from the connecting pipe 509, and then the water droplets enter the water tank 2 from the fixed pipe 511 for cooling.

[0036] When it is necessary to collect and utilize rainwater, the round rod 66 is pulled to move, and the round rod 66 drives the insertion rod 64 to move, and the insertion rod 64 drives the spring 65 to stretch, and then the insertion rod 64 is separated from the fixed block 63, and then the collection bucket 62 is pulled to move, and the collection bucket 62 drives the support rod 61 to move, and then the support rod 61 is aligned with the fixed block 63, and then the support rod 61 is inserted into the fixed block 63, and the insertion rod 64 is aligned with the fixed block 63 and the support rod 61, and then the round rod 66 is released, and the spring 65 is contracted to drive the insertion rod 64 to insert the fixed block 63 and the support rod 61 for fixation, and then in rainy weather, rainwater enters the collection bucket 62 for collection, and then the rainwater flows down from the connecting ring 67, and then the rainwater flows from the surface of the shield 501 into the water holding frame 507 and then into the water tank 2, When the flow rate of collected rainwater needs to be adjusted, the servo motor 79 is started to operate, the servo motor 79 drives the rotating shaft 76 to rotate, the rotating shaft 76 drives the auxiliary plate 77 to rotate, and then the auxiliary plate 77 and the fixed plate 78 are staggered to adjust the flow rate of rainwater, wherein the protective cover 73 and the protective shell 75 protect the servo motor 79.
