[0002] After the service life of photovoltaic modules expires, the resulting wave of scrapping and recycling problems, if not properly handled, will have a serious negative impact on the environment. Therefore, by disassembling the frame structure of waste photovoltaic devices and removing the EVA film and tempered glass encapsulation layer on the device surface; then appropriately connecting them in series according to the damage degree and voltage parameters of the photovoltaic cell devices, and then encapsulating them with conductive glass, and finally loading HER and OER catalysts on both sides of the conductive glass, the photovoltaic module can be modified into a photoelectrocatalytic device.

[0003] However, there are some problems in the prior art: The photoelectrocatalytic device modified based on waste photovoltaic devices is usually fixed on a bracket and then placed in water. By absorbing sunlight, it generates strongly reducing photogenerated electrons and strongly oxidizing photogenerated holes, which are then transferred to the catalyst on the surface of the conductive glass to participate in chemical reactions. The photoelectrocatalytic device cannot be adjusted according to the sunlight irradiation angle at different time periods and cannot make full use of sunlight. Therefore, we propose a photoelectrocatalytic device modified based on waste photovoltaic devices. Content of the Utility Model

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, a photo-electrocatalytic device based on the modification of waste photovoltaic devices provided by an embodiment of the present invention includes a bracket 1, which is welded by stainless steel pipes. The main function of the bracket 1 is to support the entire device, so that the photo-electrocatalytic device can fully absorb sunlight.

[0023] A mounting base 2 is rotatably connected to the bracket 1. A connecting block 7 is fixedly connected to the bracket 1. A rotating groove is opened at the upper end of the connecting block 7. The mounting base 2 is rotatably connected in the rotating groove. A placement groove is opened on the inner wall of the rotating groove of the connecting block 7. A first spring 8 is fixedly connected to the inner wall of the placement groove. The first spring 8 is fixedly connected to a clamping block 9. A clamping groove is opened at the bottom end of the mounting base 2. The clamping block 9 is clamped in the clamping groove.

[0024] Multiple groups of the first spring 8 and the clamping block 9 are provided. Correspondingly, the number of clamping grooves at the bottom end of the mounting base 2 is the same as that of the clamping blocks 9. When the mounting base 2 is rotated, the clamping block 9 disengages from the clamping groove of the mounting base 2. When the clamping groove rotates to the next clamping block 9, the clamping block 9 is clamped into the clamping groove of the mounting base 2 again. In this way, the cycle continues until the mounting base 2 is fixed and no longer rotates when adjusted to an appropriate angle.

[0025] A groove is opened in the middle of the mounting base 2. A rotating shaft 3 is rotatably connected in the groove. A fixing assembly 4 is arranged in the mounting base 2. The fixing assembly 4 is used to fix the rotating shaft 3. The fixing assembly 4 includes a fixing rod 401. A hole is opened on the inner wall of the groove of the mounting base 2. The fixing rod 401 is arranged in the hole. One end of the fixing rod 401 is fixedly connected to a sector block 402. An annular groove is opened at the lower end of the rotating shaft 3. The sector block 402 is adapted to the annular groove. The sector block 402 can be clamped in the annular groove.

[0026] On one side of the sector block 402, a second spring 403 is fixedly connected. The second spring 403 is fixedly connected to the inner wall of the hole. The second spring 403 is sleeved on the fixed rod 401. The outer wall of the mounting seat 2 is threadedly connected with a fixing knob 404. A chute is provided on the inner wall of the fixing knob 404. One end of the fixed rod 401 is slidably connected in the chute.

[0027] Rotate the fixing knob 404, so that the chute in the fixing knob 404 moves, thereby causing the fixed rod 401 to slide in the chute. The chute is trapezoidal. Further, the fixed rod 401 is squeezed by the fixing knob 404 to move inward against the elastic force of the second spring 403, thereby causing the sector block 402 to move inward. Further, the sector block 402 is clamped into the annular groove of the rotating shaft 3, so that the rotating shaft 3 is fixed. When the fixing knob 404 is rotated in the reverse direction, the fixed rod 401 is no longer squeezed by the fixing knob 404, and thus moves outward under the restoring force of the second spring 403, driving the sector block 402 to move outward. The sector block 402 is no longer clamped in the annular groove of the rotating shaft 3, and at this time, the rotating shaft 3 can be removed.

[0028] A frame 5 is fixedly connected to the outer wall of the rotating shaft 3. A photoelectrocatalytic assembly 6 is arranged inside the frame 5. The photoelectrocatalytic assembly 6 includes two groups of conductive glasses 601. A battery panel 602 is arranged between the two groups of conductive glasses 601. Hydrogen evolution and oxygen evolution cocatalysts are loaded on the surfaces of the two groups of conductive glasses 601. The battery panel 602 is formed by connecting multiple waste photovoltaic cells in series by the overlapping method. Immersing the photovoltaic module in toluene liquid at 90 degrees for about two days can separate the tempered glass and the photovoltaic cell from the swollen or dissolved EVA. The tempered glass is recycled. The surface of the battery chip needs to be further treated due to the adhesion of residual EVA. Heat it under certain conditions to remove the EVA on the surface, and then immerse it in a cleaning solution of ethanol and distilled water and stir to remove the impurities on the surface of the battery chip. Load platinum on the conductive glass 601 by electrochemistry. Reduce Pt ions on the conductive glass 601 by electrons. Connect the positive and negative electrodes of the series-connected battery chips to the conductive glass 601 respectively. Use the two conductive glasses 601 as two electrodes: the anode and the cathode. Load the HER and OER materials on the two electrodes respectively. Use solar energy to directly decompose water to produce hydrogen by light irradiation. Finally, to ensure the stability of the battery module and its effective absorption of light energy, waterproof encapsulation is carried out with sealant to ensure the long-term stable operation of the system in the outdoor environment.

[0029] The working principle of the present utility model is as follows:

[0030] Insert the rotating shaft 3 into the mounting base 2, and then rotate the fixing knob 404. After the fixing knob 404 rotates, it will squeeze the fixing rod 401, causing the fixing rod 401 to move inward against the elastic force of the second spring 403, thereby driving the sector block 402 to move inward, so that the sector block 402 is clamped in the annular groove of the rotating shaft 3, and then the rotating shaft 3 and the photoelectrocatalytic device on the rotating shaft 3 are fixed. At this time, rotating the rotating shaft 3 can drive the mounting base 2 to rotate, so that the mounting base 2 rotates within the connecting block 7. When the photoelectrocatalytic device rotates to an appropriate angle, the clamping block 9 will be clamped in the card slot of the mounting base 2 due to the elastic force of the first spring 8, thereby fixing the photoelectrocatalytic device.

[0031] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
