DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 4As shown in the figure, a countercurrent open cooling tower with ultra-low noise includes a water collecting tray 1 and a fixing strip 7. The outer surface of the water collecting tray 1 is annularly and equidistantly embedded and installed with an air inlet protection net 2, and the bottom of the water collecting tray 1 is annularly and equidistantly fixedly installed with support columns 3. A driving motor 10 is installed at the bottom of the water collecting tray 1, and the output shaft of the driving motor 10 is installed with a cleaning component 11 through a coupling. The cleaning component 11 includes a connecting shaft 111, an annular fixing sleeve 112, a cleaning plate 113, a limiting groove 114 and a cleaning mechanism 115. An annular fixing sleeve 112 is fixedly installed on the outer surface of the connecting shaft 111, and cleaning plates 113 are symmetrically installed on the left and right sides of the outer surface of the annular fixing sleeve 112. The inside of the annular fixing sleeve 112 is fixedly connected to the outer surface of the connecting shaft 111, and the side of the annular fixing sleeve 112 is fixedly connected to the end of the cleaning plate 113. And the cleaning plate 113 and the connecting shaft 111 form a fixed structure through the annular fixing sleeve 112. By setting the cleaning plate 113 and the connecting shaft 111 into a fixed structure, when the connecting shaft 111 drives the cleaning plate 113 to rotate, the cleaning plate 113 will not become loose. And limiting grooves 114 are equidistantly opened at the bottom of the cleaning plate 113, and a cleaning mechanism 115 is fitted and installed at the bottom of the cleaning plate 113. The cleaning mechanism 115 includes a mounting plate 1151, a cleaning brush 1152, a limiting rod 1153 and a mounting block 1154. A cleaning brush 1152 is fixedly connected to the bottom of the mounting plate 1151, and limiting rods 1153 are fixedly installed equidistantly on the top of the mounting plate 1151. The external dimension of the limiting rod 1153 is completely consistent with the internal dimension of the limiting groove 114, and the limiting rod 1153 and the cleaning plate 113 form a clamping structure through the limiting groove 114. By setting the limiting rod 1153 and the cleaning plate 113 into a clamping structure, the cleaning mechanism 115 is convenient for the staff to initially fix and install it at the bottom of the cleaning plate 113, thus providing convenience for the staff to install bolts subsequently. And mounting blocks 1154 are symmetrically installed on the left and right sides of the mounting plate 1151. At the same time, the top of the mounting block 1154 and the bottom of the cleaning plate 113 are connected by bolts in a fitting manner.

[0023] As Figure 1 and Figure 3As shown in the figure, the outer surface of the water collecting tray 1 is embedded and installed with air inlet protection nets 2 at equal intervals in a circular shape, and the bottom of the water collecting tray 1 is fixedly installed with support columns 3 at equal intervals in a circular shape. Moreover, a noise reduction component 4 is installed on the top of the water collecting tray 1. The noise reduction component 4 includes a noise reduction cover 41, a sound-absorbing cotton 42, and a sound-insulating board 43. The inner surface of the noise reduction cover 41 is fixedly installed with the sound-absorbing cotton 42, and the inner surface of the sound-absorbing cotton 42 is fixedly connected in a fitting manner with the sound-insulating board 43. Furthermore, the inner surface of the top of the noise reduction component 4 is fixedly installed with an air outlet protection net 5. At the same time, a suction fan 6 is installed on the top of the air outlet protection net 5. A fixing strip 7 is fixedly installed on the inner surface of the noise reduction component 4, and the end of the fixing strip 7 is fixedly connected with a shunt pipe 8. The end of the fixing strip 7 is fixedly connected with the inner surface of the noise reduction component 4, and the other end of the fixing strip 7 is fixedly connected with the outer surface of the shunt pipe 8. Moreover, the shunt pipe 8 and the noise reduction component 4 form a fixed structure through the fixing strip 7. By setting the shunt pipe 8 and the noise reduction component 4 into a fixed structure, the shunt pipe 8 will not loosen when carrying water. And the outer surface of the shunt pipe 8 is fixedly installed with spray pipes 9 at equal intervals in a circular shape.

[0024] In summary, for this ultra-low noise countercurrent open cooling tower, first, according to Figures 1 to 4 the structure shown in the figure, the circulating hot water enters the shunt pipe 8 from the water inlet. Then, through the cooperation of the spray pipes 9, the hot water in the shunt pipe 8 is evenly sprinkled on the packing in the noise reduction component 4. At the same time, as the suction fan 6 operates, cold air passes through the air inlet protection net 2 and enters the tower and then flows vertically upward. The cold air undergoes nearly heat exchange treatment with the hot water flowing through the packing in the packing area. The hot water after heat exchange becomes cooling water and vertically drops from the packing onto the water collecting tray 1 and flows out from the water outlet at the bottom of the water collecting tray 1. And the cold air that enters the tower interior becomes hot air after heat exchange and is discharged into the air through the air outlet protection net 5, so as to achieve the purpose of automatic cooling. And as the cooling tower operates, at this time, the noise reduction cover 41, the sound-absorbing cotton 42, and the sound-insulating board 43 cooperate with each other to automatically absorb and reduce the noise inside the tower. When the staff needs to clean the inner surface of the bottom of the water collecting tray 1, the staff turns on the drive motor 10 through the controller. When the drive motor 10 starts to operate, it drives the connecting shaft 111 to rotate inside the water collecting tray 1. Then, through the cooperation of the annular fixing sleeve 112, it drives the cleaning plate 113 to rotate synchronously, so that the cleaning plate 113 drives the cleaning mechanism 115 to automatically clean the inner surface of the bottom of the water collecting tray 1. Finally, the sewage generated by the cleaning is discharged through the water inlet and outlet main pipe at the bottom of the water collecting tray 1.
