In the case of cleaning the through-flow fan blade 5, the water pump 8 supplies water to the interiors of the outer water storage space 64 and the inner water storage space 74 through the reversing valve, so that the outer upper ring 62 and the inner upper ring 72 move upwards to form the outer cleaning space 51 and the inner cleaning space 52, water is added into the water tank 2 from the water inlet pipe on the water tank 2, the bottom of the through-flow fan blade 5 is immersed in water, and then the motor 4 drives the through-flow fan blade 5 to rotate, so that water splashes up, and the cleaning purpose is realized.
According to the technical scheme, through the arrangement of the through-flow fan blade 5, the outer water-blocking telescopic assembly 6 and the inner water-blocking telescopic assembly 7, the through-flow fan blade 5 is driven by the motor 4 to achieve the purpose of ventilation and heat dissipation, the wind speeds of all positions of the evaporation media 11 can be basically kept consistent through the through-flow fan blade 5, the ventilation and heat dissipation efficiency is improved, when the through-flow fan blade 5 needs to be cleaned, the outer water-blocking telescopic assembly 6 and the inner water-blocking telescopic assembly 7 extend upwards to form the outer cleaning space 51 and the inner cleaning space 52, so that useless space is reduced, water can be splashed higher when the through-flow fan blade 5 rotates, and the purpose of comprehensive cleaning is achieved.
Referring to fig. 8 to 10, when the through-flow fan blade 5 is cleaned, the inside of the water tank 2 is waved due to the rotation, and in order to prevent the waved flow from the evaporation medium 11 to the outside, specifically, the periphery of the water tank 2 is hinged with the wave baffle plates 9, and the ends of the adjacent wave baffle plates 9 are connected by the elastic membrane 91.
Further, the control assembly 100 is installed around the outer upper ring 62, the control assembly 100 comprises a fixed cylinder 101, the fixed cylinder 101 is fixedly connected with the outer upper ring 62, a push rod 102 is movably inserted in the fixed cylinder 101 in a transverse mode, an elastic component 103 is arranged in the fixed cylinder 101, the elastic component 103 is used for resetting the push rod 102 towards the outer side of the through-flow fan blade 5, the upper side and the lower side of the front end of the push rod 102 are inclined planes, and the push rod 102 is used for pushing the wave baffle 9 upwards or downwards.
Still further, the side wall of the water tank 2 is fixedly connected with a limiting plate 90 corresponding to the wave baffle plates 9 one by one, and when the bottom of the wave baffle plates 9 is contacted with the upper end of the limiting plate 90, the upper surface of the wave baffle plates 9 inclines towards the middle of the water tank 2.
It should be noted that, in a normal state, one end of the wave baffle 9 close to the through-flow fan blade 5 is inclined downward, so that water flowing down from the evaporation medium 11 can flow down to the inside of the water tank 2 along the surface thereof without flowing to the outside of the tank 1, when the through-flow fan blade 5 needs to be cleaned, the outer upper ring 62 moves upward, which drives the control assembly 100 to move upward, the push rod 102 pushes the end of the wave baffle 9 upward, so that the wave baffle 9 rotates upward, the elastic membrane 91 is stretched, the more the wave baffle 9 rotates upward, the greater the tension of the elastic membrane 91, therefore, the end of the push rod 102 moves a distance to the inside of the fixed cylinder 101 and then leaves the wave baffle 9, and a damping sleeve is arranged at the hinge joint of the wave baffle 9 and the water tank 2, so that the wave baffle 9 does not spontaneously rotate downward, and at this time, the wave baffle 9 and the elastic membrane 91 jointly enclose the periphery of the water tank 2, thereby preventing wave from overflowing. After cleaning, the outer upper ring 62 drives the control assembly 100 to move downwards, the push rod 102 pushes the wave baffle 9 downwards, so that the wave baffle 9 swings downwards, after the wave baffle 9 contacts with the limiting plate 90, the movement is stopped, and the push rod 102 continues to move downwards below the wave baffle 9. Wherein the elastic member 103 is a compression spring.
Referring to fig. 12 of the specification, the embodiment further provides an air flow driving method for an industrial air cooler, using an air flow driving assembly for the industrial air cooler, which includes the following steps:
When the ventilation and cooling are carried out: the motor 4 drives the through-flow fan blade 5 to rotate through the main shaft 41, so that the through-flow fan blade 5 sucks air outside the industrial air cooler into the box body 1 from the evaporation medium 11 and discharges the air from the air outlet pipe 13, and in the process, the water pump 8 supplies water to the inside of the water tank 12, so that the water flows to the evaporation medium 11;
When cleaning the cross-flow fan blade 5, the following steps are performed:
step one: the water pump 8 supplies water to the interiors of the outer water storage space 64 and the inner water storage space 74, so that the outer upper ring 62 and the inner upper ring 72 move upwards, and the through-flow fan blades 5 are positioned between the outer cleaning space 51 and the inner cleaning space 52;
Step two: adding water into the water tank 2 to enable the water to permeate through the bottom of the through-flow fan blade 5;
Step three: through-flow fan blade 5 is driven to rotate by motor 4, and through-flow fan blade 5 drives water in water tank 2 to wash the blade of through-flow fan blade 5.
