Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module cooling technology, specifically a photovoltaic module cooling device. Background Technology

[0002] Currently, photovoltaic module lamination involves placing stacked solar cells into a laminator, removing the air from the module by vacuuming, and then heating to melt the EVA to bond the cells, glass, and backsheet together. The laminated module has a high temperature.

[0003] Currently, production lines generally use air cooling to cool the components. The components cannot be completely cooled before entering the edge trimming machine. After edge trimming, there is still a certain amount of EVA residue or glue strips. Residual glue strips can easily lead to glue overflow defects or board breakage, resulting in waste of materials and manpower, which will increase production costs. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figs. 1-3This utility model provides a technical solution: a photovoltaic module cooling device, including a fixed long plate 1, a mounting groove 2 at the bottom of the fixed long plate 1, a double-headed screw 3 mounted inside the mounting groove 2 via bearings, mounting sliders 4 movably mounted at both ends of the double-headed screw 3, a fixed plate 9 mounted at the bottom of each mounting slider 4, a multi-way solenoid valve 13 mounted at the bottom of each fixed plate 9, an atomizing nozzle 12 mounted at the bottom of each multi-way solenoid valve 13, a connecting hose 14 mounted on the opposite side of each multi-way solenoid valve 13, a connecting plate 15 mounted at the end of each connecting hose 14 away from the multi-way solenoid valve 13, and a supply pump 16 mounted on the side of each connecting plate 15 away from the connecting hose 14.

[0020] A rotating hole is provided on the left side of the inner cavity of the mounting groove 2, which is located opposite to the double-headed screw 3. A working motor 8 is installed on the left side of the fixing plate 1, which is located opposite to the screw hole. The left end of the double-headed screw 3 passes through the rotating hole and is connected to the working motor 8. The working motor 8 is electrically connected to the external control center.

[0021] The specific implementation method is as follows: When processing photovoltaic modules of different sizes, the working motor 8 is started to drive the double-headed screw 3 to rotate, which simultaneously drives the mounting sliders 4 on both sides to slide inside the mounting groove 2, and drives the fixing plate 9 to move. The fixing plate 9 drives the multi-way solenoid valve 13 and the atomizing nozzle 12 to move. When the photovoltaic module moves to the relative position of the atomizing nozzle 12, the photoelectric sensor 6 is triggered. The photoelectric sensor 6 starts the supply pump 16 and the multi-way solenoid valve 13. The supply pump 16 delivers liquid water into the connecting hose 14, and sprays the liquid water out through the multi-way solenoid valve 13 and the atomizing nozzle 12, so that the liquid water comes into contact with the outside of the photovoltaic module for cooling.

[0022] Fixed pin plates 7 are installed on both sides of the fixed long plate 1, and pin holes are opened on the outside of the fixed pin plates 7. The top of the connecting plate 15 is connected to the bottom of the fixed pin plate 7, and the middle of the connecting plate 15 is opened with connecting holes. In this way, when the fixed long plate 1 is installed and fixed, the bolts are passed through the pin holes to fix the fixed pin plates 7, and the fixed long plate 1 is fixed by the fixed pin plates 7.

[0023] A water pipe is installed at the end of the supply pump 16 away from the connecting plate 15, and the end of the water pipe away from the supply pump 16 is connected to an external water supply terminal, so that liquid can be delivered to the supply pump 16 through the water pipe.

[0024] A fixing rod 5 is installed at the bottom of the connecting plate 15, and a photoelectric sensor 6 is installed at the bottom of the fixing rod 5. The photoelectric sensor 6 has a control terminal inside, and the photoelectric sensor 6 is electrically connected to the supply pump 16 and the multi-way solenoid valve 13.

[0025] Mounting plates 11 are installed on opposite sides of the multi-way solenoid valves 13 on both sides. A slot 17 is opened in the middle of the mounting plate 11. An air pump 10 is installed on the end of the mounting plate 11 away from the multi-way solenoid valve 13. The air pump 10 is electrically connected to the external control center. An air pipe is installed between the end of the mounting plate 11 away from the air pump 10 and the end of the multi-way solenoid valve 13. A docking port is opened on both sides of the mounting plate 11.

[0026] The specific implementation method is as follows: When the photovoltaic module needs to be cleaned, when the photovoltaic module is transported and moves and comes into contact with the photoelectric sensor 6, the multi-way solenoid valve 13 is triggered to open on the side near the air pump 10. The air pump 10 is started to deliver airflow into the multi-way solenoid valve 13, and the airflow is sprayed out through the atomizing nozzle 12, so that the airflow comes into contact with the outside of the photovoltaic module, thus cleaning the outside of the photovoltaic module. This avoids dirt on the outside of the photovoltaic module affecting the normal processing when it is processed in the next step. In addition, different working modes can be switched according to different needs to process the photovoltaic module, increasing the applicability during use and reducing the limitations during use.

[0027] Working principle: When processing photovoltaic modules of different sizes, the working motor 8 is started to drive the double-headed screw 3 to rotate, which in turn drives the mounting sliders 4 on both sides to slide inside the mounting groove 2, and drives the fixing plate 9 to move. The fixing plate 9 drives the multi-way solenoid valve 13 and the atomizing nozzle 12 to move. When the photovoltaic module moves to the relative position of the atomizing nozzle 12, the photoelectric sensor 6 is triggered. The photoelectric sensor 6 starts the supply pump 16 and the multi-way solenoid valve 13. The supply pump 16 delivers liquid water into the connecting hose 14, and sprays the liquid water out through the multi-way solenoid valve 13 and the atomizing nozzle 12, so that the liquid water comes into contact with the outside of the photovoltaic module for cooling.

[0028] When cleaning of photovoltaic modules is required, when the photovoltaic modules are transported and come into contact with the photoelectric sensor 6, the multi-way solenoid valve 13 is triggered to open on the side near the air pump 10. The air pump 10 is started to deliver airflow into the multi-way solenoid valve 13, and the airflow is sprayed out through the atomizing nozzle 12, so that the airflow comes into contact with the outside of the photovoltaic modules, thereby cleaning the outside of the photovoltaic modules and preventing dirt from affecting the normal processing when the photovoltaic modules are processed in the next step.
