[0002] As a water supply system in a cooling tower, the water distribution system is used to transport industrial circulating water into the cooling tower. The circulating water sprays in the tower and contacts the rising dry cold air to achieve heat exchange, so as to reduce the temperature of the circulating water. As the main component in the water distribution system, the water distribution pipe plays an important role in the normal operation of the water distribution system. The water distribution pipe generally includes a main pipe and branch pipes. There are multiple branch pipes and they are fixedly connected to the main pipe. During operation, the circulating water enters the main pipe, then enters each branch pipe, and finally is sprayed onto the packing in the tower through a nozzle. When the main pipe is connected to the branch pipe, the traditional method is to weld a section of joint on the main pipe, and then insert the branch pipe onto the joint. Due to the existence of the welded joint, the structure of the main pipe becomes prominent and the volume is large, which is not conducive to packaging and transportation. To overcome this problem, the Chinese patent document with the publication number CN210566891U discloses a pipe joint and an air duct connection structure using this joint, and a detachable structure is set between the pipe joint and the main pipe, so as to facilitate transportation. However, the pipe joint in this patent document lacks a certain positioning structure when connecting to the main pipe, resulting in the inability to quickly install the two, thus reducing the assembly efficiency of the water distribution pipe. Summary of the Utility Model

The branch pipe 3 is detachably inserted into the docking pipe 22. A positioning ring 23 is convexly provided on the side of the docking plate 21 opposite to the docking pipe 22. The positioning ring 23 is communicated with the docking pipe 22. The positioning ring 23 is inserted into the through hole 11 in cooperation. The docking plate 21 is adapted to the outer wall of the main pipe 1. A sealing member 4 is sandwiched between the main pipe 1 and the docking plate 21 and around the docking pipe 22. The docking plate 21 and the branch pipe 1 are fixedly connected by bolts 5, and the bolts 5 are located on the outside of the sealing member 4.

[0020] The water distribution pipe connection structure of the utility model has a split design between the main pipe 1 and the pipe joint 2, and the main pipe 1 itself has no protruding structure welded on its surface, which greatly facilitates transportation and reduces transportation costs. During assembly, the positioning ring 23 is first inserted into the through hole 11, and then the bolt 5 is tightened to fix the docking plate 21 on the main pipe 1, and the docking plate 21 is made to fit on the outer wall of the main pipe 1.
