[0032] By adopting the above technical solution, the spray delivery pipe 1 is connected to the water pump during use, and the water in the water pool at the bottom of the cooling tower is pumped out by the water pump and supplied to the spray delivery pipe 1. The spray delivery pipe 1 is connected to the liquid storage chamber 502 in the shell 501, so that water can be injected into the liquid storage chamber 502. The liquid storage chamber 502 can inject water into the second nozzle 701 in the tube ball seat 702 through the connecting channel 704, so that the water can be sprayed out through the second nozzle 701. When it is necessary to expand the spraying range, the load-bearing limit assembly 3 moves downward, so that the second nozzle 701 can be driven to move outward by controlling the transmission assembly 4. The second nozzle 701 can rotate in the ball cavity 703 through the tube ball seat 702, so that all the second nozzles 701 can be deployed outward, thereby expanding the water spraying range, so that the water and the air flow are in contact and then exchange heat to generate steam, and the steam evaporates and takes away the heat, thereby achieving the effect of evaporation and heat dissipation, and further improving the cooling effect of the cooling tower.

[0033] Specifically, Figure 1 , Figure 3-Figure 7As shown, the outside of the spray delivery pipe 1 is also sleeved with an adjustment control component 2, which includes an adjustment sleeve 201 fixedly sleeved on the outside of the spray delivery pipe 1, and a plurality of coils 202 and armatures 203 are embedded inside the adjustment sleeve 201, and the coils 202 are sleeved on the outer surface of the armature 203. The bearing and limiting component 3 includes a bearing sleeve 301 slidably sleeved on the outside of the spray delivery pipe 1, and the inner end surface of the bearing sleeve 301 is provided with a plurality of limiting grooves 302, and a limiting slider 303 is slidably installed inside each limiting groove 302, and each limiting slider 303 is fixed at an equal angle to the outer end surface of the spray delivery pipe 1. The control transmission component 4 includes a plurality of first assembly seats 401 fixedly installed at an equal angle on the outer end surface of the bearing sleeve 301, and the first assembly A first assembly shaft 402 is passed through the interior of the seat 401, and a telescopic sleeve rod 403 is rotatably installed in the middle position of the first assembly shaft 402. The structure of the telescopic sleeve rod 403 is an L-shaped structure, and the telescopic sleeve rod 403 includes a telescopic rod and a sleeve rod, the top of which is rotatably connected to the second assembly shaft 405, and the bottom end of the telescopic sleeve rod 403 is fixedly connected to a sleeve plate 406. The control transmission component 4 also includes a plurality of second assembly seats 404 fixedly installed at equal angles on the outer end surface of the shell 501, and a second assembly shaft 405 is passed through the interior of the second assembly seat 404, and the sleeve rod is rotatably sleeved on the second assembly shaft 405. The auxiliary spray component 8 includes a matching cavity 802 opened inside the bottom end of the shell 501, and the bottom end of the matching cavity 802 is connected to the auxiliary nozzle 801.

[0034] By adopting the above technical solution, when it is necessary to adjust the spraying range, the coil 202 inside the adjustment sleeve 201 is energized, and the armature 203 can be magnetized by the winding of the coil 202 around the armature 203. The magnetic energy of the armature 203 can attract the bearing sleeve 301 to move, and the bearing sleeve 301 can move up and down on the spray delivery pipe 1 through the limit groove 302 and the limit slider 303, so as to control the control transmission component 4. When the bearing sleeve 301 moves upward, the bearing sleeve 301 will drive the first assembly seat 401 to move upward, and the first assembly seat 401 drives the telescopic sleeve rod 403 to move upward through the first assembly shaft 402. At the same time, the telescopic sleeve rod 403 rotates on the second assembly seat 404 through the second assembly shaft 405, so that the telescopic sleeve rod 403 can push the second nozzle through the sleeve plate 406. 701 moves inward, thereby narrowing the water spraying range. Similarly, when the bearing sleeve 301 moves downward, the telescopic sleeve rod 403 pushes the second nozzle 701 to move outward through the sleeve plate 406, thereby realizing the adjustment of the spraying range; when the second nozzle 701 moves outward, the second nozzle 701 can rotate in the ball cavity 703 through the tube ball seat 702, so that the port of the second nozzle 701 can correspond to the port of the matching cavity 802, so that the connecting channel 704 can inject water between the second nozzle 701 and the matching cavity 802, and the water can be sprayed from the auxiliary nozzle 801 through the connection between the matching cavity 802 and the auxiliary nozzle 801, which can increase the spraying amount of the device. The increase in the spraying amount can increase the humidity in the cooling tower, so that the hot water and the air are in more full contact, thereby increasing the cooling effect.

[0035] Working principle: When in use, the spray delivery pipe 1 is connected to the water pump, and the water in the water pool at the bottom of the cooling tower is pumped out by the water pump and supplied to the spray delivery pipe 1. The spray delivery pipe 1 is connected to the spray component 5, and the spray component 5 can spray by connecting with the first nozzle 6 and the second nozzle 701. When it is necessary to adjust the spray range, the adjustment control component 2 is energized, and the bearing sleeve 301 is moved by magnetic absorption. The bearing sleeve 301 can move up and down on the spray delivery pipe 1, thereby driving the control transmission component 4 to move. The movement can enable the telescopic sleeve rod 403 to push the second nozzle 701 inward through the sleeve plate 406, thereby narrowing the water spray range. Similarly, when the supporting sleeve 301 moves downward, the telescopic sleeve rod 403 pushes the second nozzle 701 to move outward through the sleeve plate 406, thereby adjusting the spraying range. When the second nozzle 701 moves outward, the port of the second nozzle 701 can correspond to the port of the matching cavity 802, so that the connecting channel 704 can inject water between the second nozzle 701 and the matching cavity 802. Through the connection between the matching cavity 802 and the auxiliary nozzle 801, water can be sprayed from the auxiliary nozzle 801, which can increase the spraying amount of the device. The increase in the spraying amount can increase the humidity in the cooling tower, so that the hot water and the air are in more complete contact, thereby increasing the cooling effect.
