Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation hydrogen production technology, and specifically to a novel photovoltaic power generation hydrogen production system. Background Technology

[0002] The cost of photovoltaic power generation has dropped significantly over the past decade, while efficiency has improved remarkably, making solar energy one of the most competitive renewable energy sources. This provides an economic and technological foundation for large-scale water electrolysis to produce hydrogen using solar energy. To improve the efficiency of solar energy absorption by photovoltaic panels, they are usually equipped with automatic following systems that allow them to rotate to a suitable position based on the intensity of sunlight. However, in snowy areas, snow often accumulates on solar photovoltaic panels. If the panels rotate to a horizontal position or a position where the rotation angle deviates slightly from the horizontal position, the snow does not easily slide off, resulting in excessive snow accumulation that affects the panels' ability to absorb solar energy and convert it into electricity. This, in turn, affects the efficiency of hydrogen production. Summary of the Invention

[0003] (1) Technical problems to be solved

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a novel photovoltaic power generation hydrogen production system that allows snow to easily slide off the photovoltaic panel when the photovoltaic panel is rotated to a horizontal position or when the rotation angle deviates slightly from the horizontal position, so as to solve the above-mentioned technical problems.

[0014] (3) Beneficial effects:

[0015] A. By setting up photovoltaic modules, snow can still easily slide off the photovoltaic panels even when they are rotated to a horizontal position or when the rotation angle deviates slightly from the horizontal position.

[0016] B. By setting up the scraping component, the scraper can push off the thin layer of residual snow covering the photovoltaic panel, thereby preventing large snow accumulations from sliding off.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-11 The present invention is further illustrated by the embodiments:

[0030] A novel photovoltaic hydrogen production system includes a base 1, on which a hydrogen production device 2, a battery 3, and a photovoltaic module are fixedly mounted. The photovoltaic module includes two upright plates 10 fixedly mounted on the base 1 and a drive component 11 (in this embodiment, the drive component 11 is an electric motor). A rotating shaft 12 is rotatably mounted between the two upright plates 10. One end of the rotating shaft 12 rotatably passes through one of the upright plates 10 and is fixedly connected to the output shaft of the drive component 11. A flip plate 13 is fixedly mounted on the rotating shaft 12. Two supports 14 are fixedly mounted on the flip plate 13. A rotating shaft 15 is rotatably mounted between the two supports 14. A mounting bracket 116 is fixedly mounted on the rotating shaft 15. A photovoltaic panel 17 is fixedly mounted on the mounting bracket 116. Two springs 18 are fixedly mounted between the photovoltaic panel 17 and the flip plate 13. A photosensitive sensor 19 electrically connected to the drive component 11 is fixedly mounted on one of the supports 14.

[0031] A scraping assembly is provided on the photovoltaic panel 17. The scraping assembly includes sleeves 31 respectively disposed on both sides of the photovoltaic panel 17. A scraper 32 and a baffle 33 are fixedly disposed between the two sleeves 31. The scraper 32 is located above the side of the photovoltaic panel 17 closest to the mounting frame 116. The baffle 33 is located on the other side of the photovoltaic panel 17 and is directly opposite the scraper 32. A connecting shaft 34 is rotatably disposed between the two sleeves 31. A stop plate 35 is fixedly disposed on the connecting shaft 34. A stop head 36 is disposed on each side of the stop plate 35. A stop rod 37 that cooperates with the stop head 36 is fixedly disposed on each side of the mounting frame 116. The stop head 36 abuts against the upper side of the stop rod 37 and can reciprocate. A torsion spring is sleeved on the connecting shaft 34. One end of the torsion spring is fixedly connected to the connecting shaft 34, and the other end is fixedly connected to one of the sleeves 31.

[0032] The photosensitive sensor 19 is used to detect the intensity of sunlight. It can work with the drive unit 11 to rotate the photovoltaic panel 17 to a position where it can absorb sunlight. However, when the photovoltaic panel is rotated to a horizontal position or the rotation angle deviates from the horizontal position by a small margin, a lot of snow will accumulate on the photovoltaic panel 17. At this time, the spring 18 will flip downward under the gravity of the snow, allowing the snow to slide from the photovoltaic panel 17 onto the abutment plate 35 and the baffle plate 33. Since the quarter-sphere 351 is held in place by the abutment rod 37, the abutment plate 35 will not flip downward due to gravity. Therefore, the baffle plate 33 and the abutment plate 35 carrying the snow will move downward along the trajectory of the guide rod 119. As a result, the baffle plate 33 and the abutment plate 35 will move with the scraper 32, which can push off the thin layer of residual snow covering the photovoltaic panel 17, thereby preventing large snow accumulations from sliding off. However, the thin layer of snow still remains on the photovoltaic panel, affecting the efficiency of the photovoltaic panel in absorbing solar energy.

[0033] The mounting bracket 116 has connecting plates 118 fixedly installed on both sides, and each connecting plate 118 has a guide rod 119 fixedly installed. The sleeve 31 is reciprocally mounted on the guide rod 119, and a tension spring 120 is fixedly connected between the connecting plate 118 and the sleeve 31.

[0034] The abutment 36 has a quarter-sphere 351 and a connecting body 352. The surface of the quarter-sphere 351 that is in close contact with the abutment rod 37 is a plane, and the surface that is away from the abutment rod 37 is an arc-shaped surface. The abutment plate 35 is provided with a working groove 38. The connecting body 352 can reciprocate within the working groove 38. A return spring 39 is fixedly provided between the connecting body 352 and the inner wall of the working groove 38.

[0035] A rubber strip 353 is fixedly connected between the baffle 33 and the abutment 35 on their adjacent sides. The rubber strip 353 is used to cover the gap between the baffle 33 and the abutment 35 on their adjacent sides. The rubber strip prevents snow from entering the gap between the baffle and the abutment 35 and getting stuck.

[0036] A silicone layer is fixedly provided on the bottom surface of the scraper 32. The silicone layer prevents the scraper 32 from scratching the surface of the photovoltaic panel when cleaning it.

[0037] Each guide rod 119 has a limiting block 50 fixedly installed at a point away from the connecting plate 118.

[0038] The working principle of this invention includes the following process:

[0039] The photosensitive sensor 19 is used to detect the intensity of sunlight. It works with the drive unit 11 to rotate the photovoltaic panel 17 to a position where it can absorb sunlight. However, when the photovoltaic panel rotates to a horizontal position or a position where the rotation angle deviates slightly from the horizontal position, a large amount of snow accumulates on the photovoltaic panel 17. At this time, the spring 18 will flip downwards under the gravity of the snow, causing the snow to slide off the photovoltaic panel 17 onto the abutment plate 35 and the baffle plate 33. Since the quarter-sphere 351 is held in place by the abutment rod 37, the abutment plate 35 will not flip downwards due to gravity. Therefore, the baffle plate 33 and the abutment plate 35, carrying snow, will move downwards along the trajectory of the guide rod 119. The scraper 32 moves along with the 35, which pushes off the thin layer of snow covering the photovoltaic panel 17, thus preventing large snow accumulations from sliding off. However, the thin layer of snow still remains on the photovoltaic panel, affecting its efficiency in absorbing solar energy. When the scraper 32 moves from one side of the photovoltaic panel 17 to the other side, thus cleaning the thin layer of snow on the photovoltaic panel 17, the scraper 35 will flip downwards due to the weight of the snow, allowing the snow to fall to the ground. Then, the scraper 35 will reset under the action of the torsion spring, and the tension spring 120 will also bring the baffle 33 and the scraper 35 back to their initial positions.

[0040] By setting up the quarter-sphere 351, when the abutment plate 35 is reset, even if the quarter-sphere 351 abuts against the side or bottom surface of the abutment rod 37, because the position of the quarter-sphere 351 contacting the abutment rod 37 is the upper side surface with an arc shape, the quarter-sphere 351 will be pushed into the working groove 38. When the abutment plate 35 is reset to a position parallel to the abutment rod 37, the quarter-sphere 351 will be freed from obstruction and will move out of the working groove 38 to the upper side surface of the abutment rod 37. Since the quarter-sphere 351 in contact with the abutment rod 37 is the bottom surface with a flat shape at this time, it can once again play the role of allowing the abutment plate 35 to bear the snow.

[0041] The spring constant of the return spring 39 is less than that of the tension spring 120. Therefore, the spring force of the return spring 39 is smaller than that of the tension spring 120. When the baffle 33 and the abutment 35 are reset under the action of the tension spring 120, the quarter ball 351 can be pushed into the working groove 38 more smoothly under the action of the abutment rod 37.
