[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0018] See also Figures 1 to 3The present embodiment provides a spray mechanism 100 based on a photovoltaic cell electroplating line. The spray mechanism 100 is fixed on the electroplating line through a water inlet pipe. The spray mechanism 100 includes at least one group of water delivery pipes 10 symmetrically arranged on the electroplating line along the conveying direction of the electroplating line. The water delivery pipes 10 are connected to the water inlet pipe to deliver spray liquid; the water delivery pipes 10 are composed of a plurality of pipe sections 101, and adjacent pipe sections 101 are connected through a nozzle connection seat 20. Each nozzle connection seat 20 is provided with a blade-shaped spray head 30 connected to the nozzle connection seat 20. The spray liquid flows through the nozzle connection seat 20 one by one through the water delivery pipe 10, and then flows into the spray head 30 through the nozzle connection seat 20. The spray liquid is sprayed out through the spray head 30 to spray and clean the flowing cell, and the spray heads 30 of the upper and lower water delivery pipes 10 are arranged opposite to each other to spray both sides of the cell;

[0019] In order to keep the spraying pressure of the nozzle 30 on the same water delivery pipe 10 consistent, an adjusting member 40 is provided at the connection end between each nozzle connection seat 20 and the nozzle 30, which can adjust the water output to adjust the water spraying pressure of the nozzle 30; wherein, the nozzle connection seat 20 is provided with three interconnected and T-shaped connecting holes 201, adjacent pipe sections 101 are arranged on two horizontal holes of the T-shaped connecting hole 201, and the nozzle 30 is arranged on the vertical hole of the T-shaped connecting hole 201, and the vertical hole is connected with a joint 202, and the joint 202 has an internal threaded hole, and the nozzle 30 is threadedly connected to the joint 202, and the adjusting member 40 passes through the vertical hole and the internal threaded hole in turn, and the gap between the end face of the adjusting member 40 and the end face of the internal threaded hole is adjusted to adjust the pore size of the internal threaded hole, so as to control the amount of water flowing into the nozzle 30, thereby achieving the adjustment of the spraying pressure of the nozzle 30.

[0020] Furthermore, in the present embodiment, the adjusting member 40 is a bolt, and threaded holes are correspondingly provided on the sides of the nozzle connecting seat 20 and the joint 202. The threaded hole on the nozzle connecting seat 20 is not through, and the adjusting member 40 is threadedly connected to the threaded hole. The diameter of the adjusting member 40 is larger than the diameter of the internal threaded hole of the joint 202. When the adjusting member 40 is turned, the end of the adjusting member 40 gradually moves away from the end of the threaded hole on the nozzle connecting seat 20 that is not through, so that a hole gap is gradually formed between the end of the adjusting member 40 and the internal threaded hole, and the spray liquid flows into the nozzle 30 from the hole gap. The size of the hole gap is adjusted according to demand to control the pressure of the water sprayed by the nozzle 30. It should be noted that in order to keep the spray pressure of the nozzles 30 on the same water delivery pipe 10 consistent, how to judge the pressure of the water sprayed by each nozzle 30 can be determined by setting a pressure gauge, or by the number of counterclockwise or clockwise rotations of the adjusting member 40.

[0021] Furthermore, in this embodiment, please refer to Figure 3 and Figure 4The nozzle 30 includes a shell 301 with a hollow interior and a shell cover 302 arranged on the shell 301. Water outlet holes 303 are evenly arranged at the bottom of the shell 301, and a reinforcing plate 304 is formed at the bottom of the shell 301 between two connected water outlet holes 303. A water inlet connector 202 threadedly connected to the connector 202 is provided at the top of the shell 301. The nozzle 30 is conveniently processed and manufactured by setting the shell 301 and the shell cover 302 as described above. The reinforcing plate 304 is arranged to avoid deformation of the blade-shaped nozzle 30, and the reinforcing plate 304 is integrally formed on the shell 301.

[0022] In addition, in the present embodiment, the pipe joint 101 is made of PVC material. The PVC material has high corrosion resistance and can avoid the problem of corrosion of the pipe joint 101 during long-term use, thereby ensuring the service life of the pipe joint 101. The PVC material is light in weight and convenient for handling and loading and unloading. In addition, the pipe made of PVC material has a smooth wall surface and low fluid resistance, which is lower than other pipes. Under the same flow rate, the pipe diameter can be reduced. In other embodiments, the pipe joint 101 can be made of other corrosion-resistant materials, which will not be elaborated again.

[0023] In summary, the utility model sets an adjusting member 40 at each connection end between the nozzle connecting seat 20 and the nozzle 30, and adjusts the pore size of the cross section of the threaded hole on the joint 202 through the adjusting member 40 to adjust the water intake, thereby controlling the pressure of the nozzle 30. Furthermore, the water pressure of each nozzle 30 on the same water delivery pipe 10 can be made consistent by adjusting the adjusting member 40, so as to reduce the occurrence of defective products during cleaning.

[0024] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
