[0002] With the progress of photovoltaic cleaning technology, a bubble water cleaning process has been introduced into the battery sheet production process. The use of bubble water ensures the cleanliness of the liquid in the tank, improves the cleaning effect, and significantly improves the photoelectric conversion efficiency of the battery sheet.

[0003] Currently, when cleaning hundreds to thousands of battery sheets in a cleaning tank at the same time, how to ensure that the surface of each battery sheet can be fully cleaned is a problem that must be solved in the bubble water cleaning process. The key to solving this problem lies in how to evenly distribute the bubbles into the cleaning tank.

[0004] In terms of the existing technology, the bubble water is output in the form of a nozzle, and the output position of the nozzle is determined by the pipeline structure arranged at the bottom of the cleaning tank. To ensure uniform distribution of bubbles, the layout density of the nozzles is very high, which requires a high preparation cost. In addition, the nozzles are output in the form of a single ray, and the output effects of adjacent nozzles will also affect each other, and the action effect is not ideal. To sum up, the existing bubble uniform distribution structure has the disadvantages of high preparation cost and poor use effect. Content of the Utility Model

Detailed implementation manners

[0024] To make the purpose, technical solutions and advantages of the present utility model clearer, the following will elaborate on each embodiment of the present utility model in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present utility model, many technical details are provided for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions required to be protected by each claim of the present application can still be achieved.

[0025] To solve the above technical problems, an embodiment of the present utility model provides a bubble uniform distribution structure, as shown in Figure 1 and Figure 2 shown, the bubble uniform distribution structure includes a main pipeline 1 connected to the bubble water supply end and a plurality of branch pipelines 2 connected in parallel to the main pipeline 1. The branch pipelines 2 are connected to the multi-way joint 13 of the main pipeline 1 through a commutation member 14. The plurality of branch pipelines 2 are arranged according to the liquid tank structure. The branch pipelines 2 include a plurality of nozzles 7 evenly arranged, and the nozzles 7 on adjacent branch pipelines 2 are staggered and oppositely arranged.

[0026] Specifically, the liquid tank structure is mostly a rectangular bottom structure. When the liquid tank is in a rectangular structure, several branch pipelines 2 are arranged in parallel. Taking the structure shown in Figure 1 as an example, the number of branch pipelines 2 is two, and the reversing component 14 is a component of a right-angle elbow and a pipeline structure. Through the reversing component 14, the nozzles 7 on the branch pipelines 2 can be evenly distributed to the bottom of the liquid tank. By adjusting the number and layout of the branch pipelines 2, the bubble uniform distribution structure can be flexibly applied to cleaning tanks of different sizes and shapes, increasing the applicability and flexibility of the system.

[0027] As shown in Figures 1-3 , the main pipeline 1 also includes a main medium pipe 11. One end of the main medium pipe 11 is connected to the externally connected bubble water interface 3, and the other end is connected to the multi-way joint 13. The number of ports of the multi-way joint 13 matches the number of branch pipelines 2. Taking the structure shown in Figure 1 as an example, when there are two branch pipelines 2, the multi-way joint 13 is a three-way structure.

[0028] Among them, a pressure detector 12 is installed on the main medium pipe 11. The pressure detector 12 is connected to the industrial control end of the bubble device and is used to feedback the pressure of the bubble water entering the main medium pipe 11. If the pressure is too high, not only will energy be wasted, but also the bubbles may be too large and burst, affecting the cleaning effect; if the pressure is too low, sufficient bubbles may not be generated to meet the cleaning requirements. The pressure detector 12 provides an effective pressure feedback mechanism for the operation of the bubble uniform distribution structure, which is conducive to the industrial control end to adjust the supply pressure of the bubble water in real time, is conducive to the stability of the input end of the bubble uniform distribution structure, and also ensures the stability of the bubble supply quality.

[0029] As shown in Figure 1 and Figure 2 , the branch pipeline 2 also includes a branch medium pipe 5 and a three-way joint. The branch medium pipe 5 is connected to the port of the multi-way joint 13 through the reversing component 14.

[0030] In some embodiments, the branch pipeline 2 also includes several branch medium pipes 5 and several three-way joints. The several branch medium pipes 5 are connected in series through the several three-way joints, and reversing components 14 are respectively installed at both ends of the branch pipeline 2. Among them, the reversing component 14 at the head end is connected to the port of the multi-way joint 13, and the nozzles 7 are installed on the ports of the three-way joints and the ports of the reversing component 14 at the tail end. Optionally, the reversing component 14 is a right-angle elbow.

[0031] As shown in Figure 4As shown in the figure, the spray head 7 includes a connecting sleeve 71, a water deflecting member 72 and a uniform distribution actuator 76. The connecting sleeve 71 is connected to the branch medium pipe 5 through a tee joint. The water deflecting member 72 is hinged inside the connecting sleeve 71 through a transfer pin 73. The uniform distribution actuator 76 is installed inside the connecting sleeve 71 and is used to periodically deflect the water deflecting member 72 by means of the flow of bubble water. The bubble water entering the connecting sleeve 71 has a certain pressure. Driven by the dynamic force of the bubble water, the uniform distribution actuator 76 periodically deflects the water deflecting member 72, which can change the direction of the bubble water output from the connecting sleeve 71. Compared with the traditional jet form, the spray head 7 proposed by the present utility model can achieve a sweeping spray, with a wider coverage range, thus avoiding the cost problem caused by the high-density layout of spray heads. Moreover, the sweeping output avoids the interference between the outputs of adjacent spray heads and better preserves the bubble quality in the bubble water.

[0032] As Figure 4 and Figure 5 shown in the figure, the uniform distribution actuator 76 is installed between the water deflecting member 72 and the tee joint. The uniform distribution actuator 76 includes a mounting seat 77, an impeller 78 and a dial rod 79. The mounting seat 77 is arranged inside the connecting sleeve 71. The impeller 78 is hinged on the mounting seat 77. A dial rod 79 is eccentrically installed on the impeller 78, and the dial rod 79 contacts the water deflecting member 72. The impeller 78 rotates under the action of water power. The rotation of the impeller 78 will drive the dial rod 79 to move. The eccentrically arranged dial rod 79 contacting the water deflecting member 72 will force it to rotate around the transfer pin 73. Because of the pressure feedback mechanism provided by the pressure detector 12, the input of the bubble water is stable, and the rotation period of the impeller 78 is also relatively stable, thus realizing the periodic movement of the dial rod 79 and making the sweeping output of the bubble water stable.

[0033] Specifically, the water deflecting member 72 has a pair-drop-shaped plate structure. Its narrow end cooperates with the dial rod 79, and the hinged position of the water deflecting member 72 and the transfer pin 73 should be labor-saving for the dial rod 79, that is, the hinged position is close to the wide end of the water deflecting member 72.

[0034] Under the action of water flow, the water deflecting member 72 will automatically center and reset after being not extruded by the dial rod 79. However, this centering reset will reduce the sweeping range of the spray head 7. Therefore, it is necessary to add a water deflecting and resetting member to make the sweeping range of the spray head 7 symmetric along the axis. Specifically, the water deflecting and resetting member can be a torsion spring, and the torsion spring is connected between the water deflecting member 72 and the transfer pin 73; or an elastic band can be selected, and the elastic band is connected between the water deflecting member 72 and the mounting seat 77. By using a torsion spring or an elastic band as the water deflecting and resetting member, not only the durability of the spray head 7 is enhanced, but also the maintenance work of the spray head 7 is simplified, which is convenient for on-site rapid repair and maintenance.

[0035] Specifically, the nozzle 7 further includes a water outlet end plate 74 and a sleeve 75. The sleeve 75 is connected to the output end of the connecting sleeve 71, and the water outlet end plate 74 is fixed between the sleeve 75 and the connecting sleeve 71. A plurality of water outlet holes are formed in the water outlet end plate 74 for buffering the ejected bubble water. The sleeve 75 is used not only for fixing the water outlet end plate 74 but also for limiting the transfer pin 73.

[0036] In summary, the components of the present bubble uniform distribution structure are all made of acid and alkali resistant and corrosion resistant materials to ensure the purity of the bath solution. The acid and alkali resistant and corrosion resistant materials are preferably PTFE, PVDF, PFA, etc.

[0037] Those of ordinary skill in the art can understand that the above embodiments are specific examples for implementing the present invention, and in practical applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
