When the water distribution device is used, cooling water is sprayed to the water splashing baffle along the first water distribution pipe under certain water pressure, and the cooling water is sprayed outwards under the action of the water splashing baffle to effectively form water distribution.

In order to ensure the water distribution effect, a corresponding adjustable water distribution mechanism is respectively arranged between two adjacent fixed water distribution mechanisms, the adjustable water distribution mechanism comprises a second water distribution pipe which is communicated and connected with the water inlet pipe, and the bottom of the second water distribution pipe is rotatably provided with a corresponding rotary water distributor. In order to further ensure the water distribution effect, the self-adaptive water pressure adjusting mechanism is arranged in the second water distribution pipe of the adjustable water distribution mechanism, and the sealing plate is effectively arranged on the lower fixing plate of the self-adaptive water pressure adjusting mechanism through the elastic piece, so that the sealing plate is connected to the lower side of the upper fixing ring plate.

When the water pressure is sufficient, the closing plate is fully pressed down, the water pressure in the first water distribution pipe and the water pressure in the second water distribution pipe are both sufficient, and the water distribution effects of the fixed water distributor and the rotary water distributor are both in a better state. And as the water pressure decreases, the pressing amount of the closing plate is gradually reduced, at the moment, the water pressure in the first water distribution pipe is kept sufficient, and the water pressure in the second water distribution pipe is relatively lower. Namely, the water distribution effect of the fixed water distributor can still be effectively ensured, and the water distribution effect of the rotary water distributor can be reduced along with the reduction of the water pressure, so that the uniformly distributed fixed water distributor still has enough sputtering effect under the state that the water pressure is reduced, and all cooling nozzles, namely the water distribution effects of all the fixed water distributors and the rotary water distributor are prevented from being reduced, so that the water distribution effect can still be effectively ensured through the action of the fixed water distributors under the state that the water pressure is reduced.

2) The rotary water distributor comprises at least two annular water distribution rings which are arranged in a concentric circle manner, the height of the annular water distribution ring positioned on the outer side is lower than that of the annular water distribution ring positioned on the inner side, and arc-shaped water retaining grooves with the same track are respectively arranged on the upper end surfaces of all the annular water distribution rings in an arc shape.

When the cooling water is sprayed to the water distributor along the first water spraying pipe, the cooling water can be in full collision with the water splashing baffle step by step and finally collide with the circular water baffle, so that the spraying effect of the cooling water is further effectively improved on the premise that the first water spraying pipe keeps stable water pressure.

5) The invention also comprises a constant pressure control mechanism, wherein the constant pressure control mechanism comprises a reinforcing ring plate arranged below the lower fixing ring plate, the upper fixing device of the reinforcing ring plate is provided with a corresponding annular air bag, and the annular air bags are respectively connected to an external air compressor through corresponding air pipes and electromagnetic valves. When the pressure of intaking in the inlet tube is not enough, though the water pressure of first water-distributing pipe and inlet tube itself has effectively been kept through adjustable water distribution mechanism, but reduced the water pressure in the second water-distributing pipe, for the water distribution effect who ensures to rotate the water-locator, this application is provided with hydraulic sensor between annular gasbag and lower retaining ring board, when hydraulic sensor detects out water pressure not enough, then the solenoid valve opens, make the inboard aperture of annular gasbag reduce, thereby make the both ends of annular gasbag form great pressure differential, with effectively promoting the velocity of water flow, make rivers can be with the speed impact rotation water-locator of rapider, effectively keep the impact force of cooling water to the arc manger of annular water-distributing circle, and then effectively keep the splash of cooling water and throw away the effect.

The water pressure of inlet tube is after reduction by a relatively large margin, though can form certain pushing down to the closing plate equally, but the cooling water pressure of the second water distributor of flowing through this moment does not have the effect of driving the rotation water-locator at all, the cooling water of the second water distributor of flowing through so just has great waste, the volume of discharging of cooling water not only can be reduced to the intake through annular gasbag this moment, and can form certain reaction pressure to the closing plate, thereby reduce its pushing down volume, in order to reduce the cooling water yield of the second water distributor of flowing through, thereby under abominable operating mode, effective resources are saved.

6) The circle center of the reinforcing ring plate is provided with a corresponding fixed bearing through a plurality of corresponding connecting rod fixing devices, a corresponding mounting shaft is fixedly connected upwards at the center of the annular water distribution ring positioned at the innermost side, the upper end of the mounting shaft is fixedly connected to the inner ring of the fixed bearing, and one end of the mounting shaft positioned in the second water distribution pipe is fixedly connected with a plurality of corresponding fan blade plates.
