[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 、 Figure 2 、 Figure 3 As shown, Figure 1 The figure shows a schematic diagram of the three-dimensional structure of the water dispersion tray in the embodiment; Figure 2 What is shown is a plan view (top view) of the water dispersion tray in the embodiment; Figure 3 What is shown is a schematic diagram of the planar structure of the water dispersion tray in the embodiment;

[0023] The device includes:

[0024] A stepped disc 10, each step of the stepped disc 10 is evenly provided with a plurality of water-spreading holes 11;

[0025] The adjusting assembly 20 includes a closing block 21 movably disposed at the plurality of water-spreading holes 11 , and the closing block 21 includes at least a first state and a second state;

[0026] First state: the closing block 21 blocks the corresponding water-spreading hole 11, preventing liquid from falling from the water-spreading hole 11;

[0027] Second state: the closing block 21 does not block the liquid from falling from the corresponding water-spraying hole 11 .

[0028] Specifically, the stepped disc 10 has three steps, namely step 12, step 2 13, and step 3 14, wherein the step heights of step 12, step 2 13, and step 3 14 decrease in sequence; the water holes 11 are evenly distributed on step 12, step 2 13, and step 3 14; and a sprinkler head 30 is provided at the bottom end of the stepped disc 10 in communication with each water hole 11.

[0029] The multi-step distribution of the water-spreading holes 11 forms a step-by-step water flow path. Each step can play a certain buffering role, so that the water flow becomes more uniform when entering the next step, so that the cooling water can be more evenly covered on the packing layer, thereby improving the cooling efficiency. In addition, the number and height of the steps can be flexibly adjusted according to various cooling tower systems.

[0030] Each water scattering hole 11 may be provided with a corresponding closing block 21, or the closing blocks 21 may be provided at intervals at the water scattering holes 11. The movable closing blocks 21 may be repositioned. In a first state, the closing block 21 blocks the corresponding water scattering hole 11, preventing cooling water from falling from the water scattering hole 11, which is a closed state. In a second state, the closing block 21 does not prevent cooling water from falling from the corresponding water scattering hole 11, which is an open state.

[0031] By providing the adjustment component 20, the number of the water-spraying holes 11 in the open or closed state can be adjusted, thereby timely adjusting the number of open water-spraying holes 11 according to changes in working conditions, thereby achieving more flexible and accurate water flow control, that is, flexible control of the speed and distribution of the cooling water flow.

[0033] A rotating shaft 22 is provided on one side of the closing block 21 . The rotating shaft 22 is rotatably inserted into the stepped disk 10 . The closing block 21 is switched to the first state or the second state by the rotation of the rotating shaft 22 .

[0034] The closing block 21 is rotatably mounted by a rotating shaft 22 provided on the closing block 21 , so as to adjust the position of the closing block 21 and the corresponding water-spraying hole 11 .

[0035] A support frame 40 is further provided at the bottom of the stepped disc body 10 , and the end surface of the support frame 40 close to the stepped disc body 10 matches the shape of the stepped disc body 10 .

[0036] The support frame 40 is provided with a corresponding paving portion at the water-sprinkling hole 11 of the stepped disk 10 and the sprinkler head 30;

[0037] The support frame 40 supports the stepped disc body 10, and the stepped disc body 10 and the support frame 40 both act as reinforcing ribs. The setting of the support frame 40 can further increase the strength of the water dispersion pan, avoiding the problem of local sinking of the water dispersion pan after long-term use, thereby improving the water dispersion effect and service life.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
