[0003] The currently published patent: CN219589477U discloses a closed cooling tower. The gas or liquid to be cooled enters the heat exchange component, and the wind component sucks in external cold air, that is, the cold air flows from the air inlet hood into the cooling tower, so that the cold air moves from bottom to top to further cool the heat exchange component, and the water supply component pumps the water in the water storage tank upward and sprays it downward from the spray component. This part of the cooling water falls on the surface of the heat exchange component, so that the gas or liquid in the heat exchange component is further cooled, and the water after spraying falls into the water storage tank, and the spray water is efficiently recovered.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the closed cooling tower is in use, the water in the water storage tank is pumped upward and sprayed downward from the spray assembly. This part of the cooling water falls on the surface of the heat exchange assembly for cooling. Since the spray assembly is fixedly installed inside the cooling tower, the staff cannot adjust the water spraying angle of the spray assembly according to demand, which affects the cooling effect of the heat exchange assembly.

The spray pipe adjustment device comprises five gears 5, a trapezoidal guide rod 6, slider 7, tooth plate 8, protrusion 9 and hydraulic telescopic rod 10, the five gears 5 are respectively sleeved on the right ends of the five spray pipes 3, the trapezoidal guide rod 6 is fixedly connected to the right side of the closed cooling tower 1, the slider 7 is slidably connected to the surface of the trapezoidal guide rod 6, the tooth plate 8 is fixedly connected to the top of the slider 7, the five gears 5 are evenly meshed with the tooth plate 8, the protrusion 9 is fixedly connected to the bottom of the slider 7, the hydraulic telescopic rod 10 is fixedly installed on the right side of the closed cooling tower 1, and the telescopic end of the hydraulic telescopic rod 10 is fixedly connected to the surface of the protrusion 9.

[0026] When the staff needs to adjust the water spraying angle of the spray pipe 3, the staff starts the hydraulic telescopic rod 10 and drives the protrusion 9 to slide. The sliding of the protrusion 9 can drive the slider 7 to slide back and forth on the surface of the trapezoidal guide rod 6. The slider 7 is limited by the trapezoidal guide rod 6 to ensure that the slider 7 slides back and forth horizontally. The slider 7 slides and drives the tooth plate 8 to slide back and forth.

[0029] Working principle: In the closed cooling tower which is convenient for adjusting the spraying angle, the staff starts the hydraulic telescopic rod 10 and drives the protrusion 9 to slide. The sliding of the protrusion 9 can drive the slider 7 to slide back and forth on the surface of the trapezoidal guide rod 6. The slider 7 is limited by the trapezoidal guide rod 6 to ensure that the slider 7 slides back and forth horizontally. The slider 7 slides and drives the tooth plate 8 to slide back and forth. The tooth plate 8 slides to drive the five gears 5 to rotate at the same time, and drives the five spray pipes 3 to rotate at the same time to adjust the spraying angle of the water spray hole 4.
