[0060] The first baffle 128 is provided with a through groove and a flap 131. The top of the flap 131 is rotatably connected to the first baffle 128. The flap 131 covers the through groove to close it. The setting of the flap 131 enables the through groove to open unidirectionally, and the through groove is opened when the water flows in the direction away from the spray water pump 108. Both the first baffle 128 and the second baffle 129 are filter plates with small apertures. The first baffle 128 and the second baffle 129 have the same structure, and the structure of the fourth slider is the same as that of the third slider 1281.

[0061] The spray pipe 104 is connected to the spray water pump 108 through a pipeline 110. A water storage bin 109 is provided on the pipeline 110 connected to the spray water pump 108, and a valve is provided at one end of the water storage bin 109.

[0062] For the convenience of description, the top of the chute is called the top horizontal section, the bottom is called the bottom horizontal section, the side close to the spray water pump 108 is called the first vertical section, and the side far from the spray water pump 108 is called the second vertical section. The fourth movable groove is at the intersection of the first vertical section and the bottom horizontal section, and the fifth movable groove is at the intersection of the second vertical section and the bottom horizontal section.

[0063] When the filter screen 130 at one of the water outlets is blocked, the valve of the water storage chamber 109 connected to the spray water pump 108 is closed, and water is injected into the water storage chamber 109. The other spray water pump 108 works normally to supply water to the spray pipe 104 and the water delivery pipe 119; the first baffle 128 abuts against the bottom surface of the water collection cavity, and the second baffle 129 is in a raised state, that is, the third slider 1281 is at the intersection of the second vertical section and the bottom horizontal section, and the fourth slider is within the top horizontal section; after the water storage chamber 109 is filled with water, the spray water pump 108 works in reverse to convey the water in the water storage chamber 109 into the filter screen 130, so that the water flows outwards from the inside of the filter screen 130 to backwash the filter screen 130. The blockage on the filter screen 130 is washed away by the impact of the water flow and mixed into the water in the water collection cavity; at this time, the first conveyor belt 132, the second conveyor belt 133 and the third conveyor belt 138 rotate to drive the fourth slider to move. The transmission block 136 on the third slider 1281 is in a raised state. The third slider 1281 does not form a transmission with the conveyor belt, and the third slider 1281 stays in the chute, that is, the first baffle 128 does not move, and the second baffle 129 moves along the chute. After the second baffle 129 is conveyed by the conveyor belt from the top horizontal section to the first vertical section, the fourth slider moves down along the first vertical section to the bottom horizontal section. The fourth slider abuts against the first push rod 139 to push the first push rod 139 to move. The first push rod 139 pushes the second transmission rod 141 to rotate. The second transmission rod 141 pushes the second push rod 142 to move. The second push rod 142 extends out of the fifth movable groove to push the third slider 1281 to move. The third slider 1281 moves into the second vertical section so that the third slider 1281 contacts the first conveyor belt 132 to form a transmission fit. At this time, both the third slider 1281 and the fourth slider move in the chute, that is, the first baffle 128 rises upwards, and the second baffle 129 moves away from the spray water pump 108. The movement of the second baffle 129 is used to collect the blockage cleaned from the filter screen 130 at one end of the water collection cavity away from the spray water pump 108.

[0064] When the fourth slider moves to the intersection of the bottom horizontal section and the second vertical section, the push block 144 abuts against the transmission block 136 to push the transmission block 136 to move. The transmission block 136 rises and disengages from the third conveyor belt 138. The second baffle 129 abuts against the bottom surface of the water collection cavity to form a collection area in the water collection cavity, and the first baffle 128 is in a raised state.

[0065] By using the alternating movement of the first baffle 128 and the second baffle 129, the cleaned blockage is continuously collected in the collection area, reducing the dust precipitation in the circulating water and ensuring the normal operation of the spray water pump 108.

[0066] A backing plate 143 is provided at the bottom of the water collecting cavity. The backing plate 143 is located within the collecting area formed by the first baffle 128 and the second baffle 129. By removing the backing plate 143 from the water collecting cavity, it is convenient to clean the collecting area, reducing the maintenance difficulty of the cooling tower.
