The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] like Figure 1-4 As shown, this embodiment provides a water distribution device, including a water distribution pipe 1 and a plurality of water outlet pipes 2, wherein the plurality of water outlet pipes 2 are connected to the water distribution pipe 1 so as to allow the water flow in the water distribution pipe 1 to be output.

[0044] In some embodiments, at least two water outlet pipes 2 are provided.

[0045] In some embodiments, the upper end of the water outlet pipe 2 extends into the water distribution pipe 1, and the upper ends of two or more water outlet pipes 2 jointly form a lower water surface, and the height of the lower water surface is higher than the height of the bottom wall of the water distribution pipe 1.

[0046] By extending the upper end of the water outlet pipe 2 into the water distribution pipe 1 and forming the lower water surface, and then making the position of the lower water surface higher than the bottom wall of the water distribution pipe 1, when the device is in use, water with a sufficient water level needs to be stored in the water distribution pipe 1 before it is output from the water outlet pipe 2, which is convenient for improving the uniformity of water distribution; it can effectively avoid the problem of uneven water distribution caused by the direct connection between the water outlet pipe and the water distribution pipe in traditional technology and the direct output of water from the nearest water outlet pipe when the water flow is small, thereby improving the application effect of the device.

[0047] In some embodiments, Figure 1As shown, the outlet pipe 2 is connected to the water distribution pipe 1 through a reducing tee joint, and the smaller diameter section of the reducing tee joint serves as the outlet pipe 2; during installation, the smaller diameter section of the reducing tee joint is vertically arranged.

[0048] In some embodiments, the connection point between the water outlet pipe 2 and the water distribution pipe 1 can be set on the side wall of the water distribution pipe 1, so that it can have a certain position height relative to the bottom wall of the water distribution pipe 1. At this time, a similar uniform water distribution effect can be achieved; however, during installation, the number of curved sections of the pipeline increases, which easily leads to an increase in application costs.

[0049] As one application example, the water outlet pipe 2 is provided with a protruding section 21 in the water distribution pipe 1, and a plurality of lower water tanks 22 are provided on the side wall of the protruding section 21; at this time, the bottom wall surfaces of the plurality of lower water tanks 22 together form the lower water surface, which can be referred to Figure 3 shown.

[0050] In some embodiments, the lower water tanks 22 can be provided in two or more portions and are evenly arranged around the axis of the water outlet pipe 2 .

[0051] In some embodiments, two lower water tanks 22 are provided and are arranged in a rectangular shape.

[0052] By designing the size of the lower water tank 22 , it is convenient to set the height of the lower water surface and to control the flow of lower water from the water distribution pipe 1 to the water outlet pipe 2 .

[0053] In some embodiments, the lower water tank 22 is arranged toward the inner wall of the water distribution pipe 1; an example is given when two lower water tanks 22 are arranged. At this time, the surface of the water outlet pipe 2 facing the water flow direction in the water distribution pipe 1 is a complete wall structure, such as Figure 4 shown.

[0054] When in use, the water flow in the water distribution pipe 1 can be guided by the complete wall structure on the water outlet pipe 2 to prevent the water flow from colliding with the wall structure on the water outlet pipe 2 located at the bottom of the lower water trough 22 when the flow rate of the water flow in the water distribution pipe 1 is high, causing the water to flow out of the water outlet pipe 2, which can improve the stability of the water flow during circulation and the uniformity of water distribution.

[0055] In some embodiments, the other ends of the plurality of water outlet pipes 2 are arranged downward for communicating with external equipment, such as a cooling tower; a first control valve 23 is arranged on the water outlet pipe 2. The water flow output of the water outlet pipe 2 can be controlled by the first control valve 23.

[0056] As one application example, an exhaust hole 11 is provided on the top wall of the water distribution pipe 1; the exhaust hole 11 can be used to release pressure inside the water distribution pipe 1 to improve the flow stability of the water flow and facilitate maintaining the level of the water surface in the water distribution pipe 1.

[0057] In some embodiments, the water distribution device further includes a plurality of water inlet pipes 3, and the plurality of water inlet pipes 3 are connected to the water distribution pipe 1; by setting up the plurality of water inlet pipes 3, water supply to the water distribution pipe 1 can be easily achieved.

[0058] In some embodiments, the height of the connection point between the water inlet pipe 3 and the water distribution pipe 1 is higher than the height of the axis of the water distribution pipe 1; at this time, direct connection between the output end of the water inlet pipe 3 and the water surface in the water distribution pipe 1 and the water flow below the water surface can be avoided.

[0059] As one application example, the water diversion pipe 1 includes a water inlet section 12 and a water diversion section 13, the plurality of water inlet pipes 3 are connected and arranged on the water inlet section 12, and the plurality of water outlet pipes 2 are connected and arranged on the water diversion section 13; and an arc-shaped transition section 14 is arranged between the water inlet section 12 and the water diversion section 13.

[0060] In some embodiments, the water distribution pipe 1 can be set in a linear shape, such as a straight line, a wavy shape, etc.; in this case, the water distribution pipe 1 has a starting end and an end, and the water inlet pipe 3 can be connected to the starting end and the end of the water distribution pipe 1 respectively.

[0061] In some embodiments, the water distribution pipe 1 can be arranged in an annular shape, including a circular ring or a loop structure composed of a polygon. Here, the case where it is arranged in a rectangular shape is used as an example for explanation; in this case, the water inlet pipe 3 is arranged on one relative pipe section of the water distribution pipe 1, and the water outlet pipe 2 is arranged on the other relative pipe section of the water distribution pipe 1, such as Figure 1 shown.

[0062] By setting the arc-shaped transition section 14, the impact of water flow impact on the output flow of water to the water outlet pipe 2 after the water flows from the water inlet pipe 3 into the water distribution pipe 1 can be reduced, thereby facilitating improving the stability of the water flow when flowing in the water distribution pipe 1.

[0063] On the other hand, Figure 1-4 As shown, this embodiment provides a cooling tower water distribution system, including a plurality of cooling towers 4, wherein the plurality of cooling towers 4 form a cooling tower group, and the water distribution device as described above is arranged on the cooling tower group.

[0064] In some embodiments, at least two cooling towers 4 are provided, and a connecting pipe 41 is provided at the bottom between two adjacent cooling towers 4, and a second control valve 42 is provided on the connecting pipe 41. By providing the connecting pipe 41 and the second control valve 42, it is convenient to balance the water levels in at least two cooling towers 4.

[0065] In some embodiments, a drain pipe 5 is provided at the bottom of the cooling tower group, and a drain connecting pipe 43 is correspondingly provided at the bottom of each cooling tower 4, and the drain connecting pipe 43 is connected to the drain pipe 5; and a third control valve 44 is provided on the drain connecting pipe 43.

[0066] By setting the drainage connecting pipe 43 and the third control valve 44, it is easy to achieve communication between the single cooling tower 4 and the drainage pipe 5, so that the water flow in the single cooling tower 4 can be controlled to be output to the drainage pipe 5; and the set drainage pipe 5 can facilitate the output of the water flow to the next process.

[0067] By applying the water distribution device provided in the cooling tower water distribution system of this embodiment, it is possible to improve the application effect of the system under low load conditions and improve the uniformity of water distribution.
