[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature to ensure the normal operation of the system.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-3 The utility model provides a technical solution: a cooling tower nozzle, including a pipe body assembly 1, the pipe body assembly 1 includes a water storage pipe 11, a connecting pipe 12 and a water outlet pipe 13, the bottom of the water storage pipe 11 is fixed and connected with the connecting pipe 12, the bottom of the connecting pipe 12 is fixed and connected with the water outlet pipe 13, and a cleaning assembly 2 is arranged inside the connecting pipe 12;

[0032] Among them, the cooling water enters the water storage pipe 11, and enters the connecting pipe 12 from the water storage pipe 11. The connecting pipe 12 is thick at the top and thin at the bottom. The water pressure of the cooling water will increase when it flows downward. The pressurized cooling water flows out from the water outlet pipe 13. During the flow of the cooling water, the cleaning component 2 helps to clean the inner wall of the connecting pipe 12.

[0033] The cleaning assembly 2 includes a rotating rod 21, a mounting frame 22 and a scraper 23. A cross bar 26 is fixedly connected to the top of the inner wall of the connecting tube 12. The bottom of the cross bar 26 is rotatably connected to the rotating rod 21. Two mounting frames 22 are fixedly connected to the circumference of the rotating rod 21. Two scrapers 23 are fixedly connected to the two sides of the two mounting frames 22. The two scrapers 23 movably contact the inner wall of the connecting tube 12.

[0034] When cleaning, the rotating rod 21 is rotated, and the rotating rod 21 rotates on the cross bar 26. The rotation of the rotating rod 21 drives the mounting frame 22 to rotate, and the rotation of the mounting frame 22 drives the scraper 23 to rotate. The scraper 23 cleans the inner wall of the connecting pipe 12 to prevent impurities from sticking to the inner wall of the connecting pipe 12, thereby ensuring that the connecting pipe 12 is unobstructed.

[0035] A control assembly 3 is provided inside the water outlet pipe 13;

[0036] Among them, the control component 3 can ensure the constancy of water pressure.

[0037] Specifically, Figure 1-3 As shown, a turntable 24 is fixedly sleeved on the bottom circumference of the rotating rod 21, and a plurality of blades 25 are fixedly connected to the top surface of the turntable 24. A plurality of water outlet holes 6 are opened through the circumference of the water outlet pipe 13, and the water outlet holes 6 are shaped as downward arc-shaped channels. The turntable 24 is located below the outside of the water outlet pipe 13.

[0042] When the device is used, the installation pipe 14 is installed to the reserved joint of the cooling tower water supply pipeline by using the thread 15, and the installation plate 5 is fixed to the installation position by bolts to complete the installation. The cooling water enters the water storage pipe 11 from the installation pipe 14, and enters the connecting pipe 12 from the water storage pipe 11. The connecting pipe 12 is thick at the top and thin at the bottom. The cooling water will increase the water pressure when it flows downward. The pressurized cooling water squeezes the annular sheet 31 downward. The cooperation between the annular sheet 31 and the water outlet pipe 13 compresses the spring 32. The control component 3 can keep the water pressure constant. After the cooling water enters the water outlet pipe 13, it is discharged from the water outlet hole 6. The water outlet 6 is a downward arc-shaped channel. After the cooling water flows out, it rushes to the blades 25. The blades 25 are inclined toward the water outlet 6. The blades 25 drive the turntable 24 to rotate. The rotation of the turntable 24 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the mounting frame 22 to rotate. The rotation of the mounting frame 22 drives the scraper 23 to rotate. The scraper 23 cleans the inner wall of the connecting pipe 12 to prevent impurities from sticking to the inner wall of the connecting pipe 12, ensuring that the connecting pipe 12 is unobstructed. The turntable 24 is high in the middle and low on all sides. The cooling water falls from the turntable 24 and flows onto the conical disk 8, and flows downward from the water guide rod 9 on the conical disk 8.
