An electrically controlled flip-type spray guide device 5 is movably assembled on the inner side surface of the side-hung guide frame 3, and an electrically controlled flip-type bottom guide and drainage device 6 is movably assembled on the inner side surface of the side-hung assembly frame 4. Temperature monitoring and control modules 7 are installed on the side walls of both the electrically controlled flip-type spray guide device 5 and the electrically controlled flip-type bottom guide and drainage device 6.
[0024] To cooperate with the circulating diversion, a bottom-mounted circulating water collection tank 8 is fixedly assembled on the inner bottom surface of the cooling tower housing 1. An internal circulating liquid pumping pump 9 is installed inside the bottom-mounted circulating water collection tank 8, and the internal circulating liquid pumping pump 9 is fixedly connected to the inside of the side-hung guide frame 3 through a vertical drainage pipe 10.
[0025] The internal circulating liquid pumping pump 9 starts to pump the coolant inside the bottom-mounted circulating water collection tank 8 into the side-hung guide frame 3 through the vertical drainage pipe 10, and then automatically controls the electrically controlled flip-type spray guide device 5 and the electrically controlled flip-type bottom guide and drainage device 6 to flip to the upper and lower ends of the spray filler 2 through the temperature monitoring and control module 7. Then, it automatically controls the flip angles of the electrically controlled flip-type spray guide device 5 and the electrically controlled flip-type bottom guide and drainage device 6, as well as the spray volume of the electrically controlled flip-type spray guide device 5 according to the temperature difference.
[0026] To cooperate with the lateral movable assembly, a top-side installation groove 31 is opened on the inner side wall of the side-hung guide frame 3, and lateral assembly through holes for installing and connecting the electrically controlled flip-type spray guide device 5 are symmetrically opened on both inner side walls of the top-side installation groove 31.
[0027] To cooperate with the electric control and spray control, the electrically controlled flip-type spray guide device 5 includes an upper flip adjustment arm 51 that is movably connected to the side-hung guide frame 3 by inserting both side shaft tubes into the lateral assembly through holes, an upper hydraulic strut 52 for controlling the upper flip adjustment arm 51, an upper arc-shaped guide cover 53 fixed to the lower end of the upper flip adjustment arm 51, and an embedded upper spray nozzle 54 fixed to the inner top surface of the upper arc-shaped guide cover 53.
[0028] The upper hydraulic strut 52 controls the flipping of the upper flip adjustment arm 51 and the upper arc-shaped guide cover 53 by telescoping, and then uses the embedded upper spray nozzle 54 to spray the coolant introduced by the internal circulating liquid pumping pump 9 into the spray filler to cool the air.
[0029] When idle, the embedded upper spray nozzle 54 on the upper arc-shaped guide cover 53 sprays and cools the air at the upper end of the spray filler from an inclined direction.
[0030] In order to cooperate with the movable assembly of the electric control flip-type bottom-mounted diversion and drainage device 6, a bottom-side installation groove 41 is provided on the side wall at the lower end of the side-mounted assembly frame 4.

[0032] The lower hydraulic strut 62 controls the flip adjustment of the lower arc-shaped diversion cover 63 and the lower flip adjustment arm 61 through telescopic adjustment.
[0033] In order to improve the assembly fit, lateral assembly grooves 11 are symmetrically provided on both sides of the lower end of the upper arc-shaped diversion cover 53 and both sides of the upper end of the lower arc-shaped diversion cover 63.
[0034] In order to cooperate with the internal diversion and electronically control the flux size, an internal liquid flow channel 511 for connecting the shaft tubes on both sides and the embedded upper spray nozzle 54 is provided inside the upper flip adjustment arm 51, and an electronically controlled regulating valve 512 is fixedly assembled inside the internal liquid flow channel 511.
[0035] The temperature monitoring and control module 7 monitors the temperature of the lower air inlet and the upper air outlet of the spray packing on the side walls of the electric control flip-type spray diversion device 5 and the electric control flip-type bottom-mounted diversion and drainage device 6 respectively. Through the preset maximum temperature, when the temperature of the air outlet exceeds the set maximum temperature, at this time, the temperature monitoring and control module 7 will activate the electronically controlled regulating valve 512, introduce the spray water into the internal liquid flow channel 511 through the side-mounted diversion frame 3, and then spray the spray liquid through the embedded upper spray nozzle 54 into the spray packing through the internal liquid flow channel 511; When the cooling effect is limited after spraying, at this time, the upper hydraulic strut 52 extends to control the upper flip adjustment arm 51 and the upper arc-shaped diversion cover 53 at its lower end to flip downward and close the upper opening of the spray packing 2 at intervals, and use the embedded upper spray nozzle 54 on the inner top surface of the upper arc-shaped diversion cover 53 to spray the inside of the spray packing 2; and at this time, the lower hydraulic strut 62 extends to control the lower flip adjustment arm 61 and the lower arc-shaped diversion cover 63 at its upper end to flip upward and close the lower opening of the spray packing 2 at intervals.
[0036] The upper arc-shaped diversion cover 53 and the lower arc-shaped diversion cover 63 are clamped on the upper and lower ends of the spray packing in a staggered layout manner, so as to form a serpentine structure layout flow channel from the originally longitudinally arranged flow channels, thereby increasing the single flow travel and extending the cooling travel of the air, so as to increase the cooling effect.
[0037] When post-maintenance is required, all the upper arc-shaped deflectors 53 and lower arc-shaped deflectors 63 are controlled to close the spray packing, and then the inside of the spray packing is cleaned.

[0039] When the upper flipping adjustment arm 51 flips upward, the upper hydraulic strut 52 will flip into the upper storage groove 513 for storage, thereby improving the flipping fit; when the lower flipping adjustment arm 61 flips downward, the lower hydraulic strut 62 will flip into the lower storage groove 611 for storage, thereby improving the flipping fit.
[0040] To cooperate with the lateral drainage and maintenance, an arc-shaped drainage groove 42 is provided inside the side-mounted assembly frame 4, a bottom-side drainage groove 12 is provided inside the lower flipping adjustment arm 61 and the lower arc-shaped deflector 63, an embedded bottom one-way drainage valve 13 communicating with the arc-shaped drainage groove 42 is fixedly assembled at the lower end of the side-mounted assembly frame 4, an outer maintenance port communicating with the bottom-side drainage groove 12 is provided on the outer side surface of the cooling tower housing 1, and a detachable sealing cover plate 14 is installed inside the outer maintenance port.
[0041] The embedded bottom one-way drainage valve 13 can drain the reflux liquid downward, but the air at the bottom cannot be introduced.
[0042] The reflux liquid flowing out of the lower opening of the spray packing flows into the bottom-side drainage groove 12, then flows into the arc-shaped drainage groove 42 along the bottom-side drainage groove 12, and then the backflow water falls back into the bottom-mounted circulation water collection tank 8 through the embedded bottom one-way drainage valve 13. When there is a blockage inside, the detachable sealing cover plate 14 is opened, and then people can perform maintenance operations from the outside of the cooling tower housing 1.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
