Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a sunshade based on a perovskite solar cell. Background Art

[0002] Perovskite solar cells are a new type of high-efficiency, low-cost photovoltaic power generation technology, belonging to the third generation of solar cells, also known as new concept solar cells. The utility model patent with the authorization announcement number CN220756764U discloses a parasol based on perovskite solar cells, which relates to the field of umbrellas, including a main pole, a frame arranged on the main pole, and an umbrella surface covered on the frame, on which a perovskite solar photovoltaic film is laid, a battery for storing electricity is arranged on the main pole, and an opening and closing mechanism for electrically folding and opening the frame is also arranged on the main pole. The perovskite solar photovoltaic film is used to absorb solar energy for power generation, and the electric energy is stored in the battery. When the parasol needs to be opened, it can be automatically opened by pressing the switch through the opening and closing mechanism, and it can be closed by pressing the switch, which is very convenient and avoids scratches or bullet injuries during the manual opening process. When walking on a rainy night, the light bar on the umbrella can be turned on to form a three-dimensional umbrella-shaped light source on the umbrella surface, which can illuminate the road surface for the user on the one hand, and on the other hand, it can facilitate the attention of passing vehicles to avoid traffic accidents.

[0018] The beneficial effect of this improvement is that the fixing plate cooperates with the pressing plate to effectively clamp and lock the top of the perovskite solar photovoltaic film umbrella, thereby ensuring the stability of the installation of the perovskite solar photovoltaic film umbrella.

[0019] In order to ensure a stable water flow to the rotating spray assembly;

[0020] As a further improvement of the above technical solution: the umbrella pole is a round tube structure with an open top.

The spray port 112 is eccentrically opened on the self-rotating nozzle 111. After the water flow is sprayed out from the multiple eccentrically opened spray ports 112, the rotary spray assembly 11 is driven to rotate as a whole under the reaction force of the water flow, so that the water flow can evenly cover and wash the surface of the perovskite solar photovoltaic film umbrella 12. The top of the umbrella rod 5 is provided with an annular convex block structure, and the self-rotating nozzle 111 is provided with an annular The groove structure, under the action of the annular protrusion set at the top of the umbrella pole 5, the rotating spray assembly 11 can rotate stably on the umbrella pole 5 as a whole to avoid falling off. The bottom of the guide plate 113 is provided with a truncated cone-shaped groove structure that is narrow at the top and wide at the bottom. The truncated cone-shaped groove at the bottom of the guide plate 113 can play a diversion role, so that the water sprayed from the spray port 112 is diverted to the surface of the perovskite solar photovoltaic film umbrella surface 12, and the surface of the perovskite solar photovoltaic film umbrella surface 12 is effectively washed. A fixing plate 51 is fixedly provided on the umbrella pole 5, and the fixing plate 51 is connected with a pressing plate 52 by bolts.
