Description

Technical Field

[0002] At a time when energy demand is growing and environmental awareness is constantly improving, the development and utilization of solar energy, as a clean and renewable energy source, has attracted much attention. Photovoltaic power generation systems have become an important way to utilize solar energy due to their many advantages. They are widely deployed around the world, from large-scale solar power stations to small distributed photovoltaic power stations, injecting green power into the energy supply system.

[0003] Photovoltaic panels, as the core components of photovoltaic power generation systems, operate by absorbing sunlight and converting it directly or indirectly into electrical energy through the photoelectric or photochemical effects. Obviously, the more solar radiation a photovoltaic panel receives, the more electricity it generates. However, after a snowfall or after prolonged operation, photovoltaic panels are often covered with accumulated snow or dust. Once this occurs, the photovoltaic panel's photoelectric conversion efficiency is significantly reduced, seriously affecting the overall performance and power generation of the photovoltaic power generation system.

[0004] Currently, manual cleaning is the most common method for cleaning photovoltaic panels. This involves rinsing with water or using tools like mops to clean each panel individually. This method is feasible for a small number of panels that are easily accessible for manual cleaning. However, in large-scale photovoltaic power generation projects, the number of panels requiring cleaning often reaches tens of thousands, and some are located in unusual locations, making manual access extremely difficult. In such cases, manual cleaning consumes significant manpower and material resources and poses numerous safety risks.

[0044] The photovoltaic assembly includes a photovoltaic bracket 1 and an installation bracket 7. A groove for installing the photovoltaic panel is reserved on the outside of the photovoltaic bracket 1. During installation, first connect the photovoltaic bracket 1 to the ground, then install the photovoltaic panel in the corresponding groove of the photovoltaic bracket 1, debug the circuit, and fix the installation bracket 7 on the side wall of the photovoltaic bracket 1.

When there is debris (dust, snow, etc.) on the photosensitive surface of the photovoltaic panel, the sliding adjustment beam 4 drives the cleaning strip 9 to slide along the surface of the photovoltaic panel. The cleaning strip 9 scrapes the surface of the photovoltaic panel, thereby cleaning the debris that falls on the surface of the photovoltaic panel and maintaining the photoelectric conversion efficiency of the photovoltaic panel.

[0047] The storage part includes a storage box 2 and a filter layer 5.

[0062] The reciprocating screw 24 passes through the transmission ring 27 and is connected to the transmission ring 27 by means of internal and external threads. Rotating the reciprocating screw 24 drives the transmission ring 27 to slide back and forth, thereby driving the control plug 22 to slide back and forth, thereby controlling the rainwater inside the storage box 2 to enter the inner cavity of the mounting tube 13, and then enter the chamber on one side of the support plate 11, and finally enter the inner cavity of the storage box 2 again from the chamber on one side of the support plate 11.

At this time, the transmission ratchet 31 and the transmission ratchet rod 29 slip. When the guide vane 26 rotates reversely, the transmission ratchet 31 is driven to rotate by the transmission ratchet rod 29, thereby controlling the rotation of the reciprocating screw 24, and then controlling the internal circulation flow of rainwater in the inner cavity of the storage box 2 to prevent the growth of algae.

[0066] A truncated cone-shaped cover 18 is fixedly mounted on the inner wall of the control frame 14 , with the top surface of the truncated cone-shaped cover 18 facing the control cylinder 15 .

The sealing plug 34 is located directly below the liquid inlet cylinder 33. When the temperature in the inner cavity of the storage box 2 rises, the alcohol in the inner cavity of the storage cylinder 12 expands, thereby controlling the sliding plug 28 to slide upward, driving the sealing plug 34 to seal the bottom of the liquid inlet cylinder 33, closing the liquid inlet cylinder 33, and thereby reducing the evaporation loss of the liquid in the storage box 2.

A new energy photovoltaic power generation device for automatic dust and snow removal according to claim 2, characterized in that: The inner cavity of the storage box (2) is fixedly mounted with a mounting plate (16), the outer wall of the mounting plate (16) is fixedly mounted with a storage cylinder (12), the inner cavity of the storage cylinder (12) is slidably mounted with a sliding plug (28), the upper end surface of the sliding plug (28) is fixedly mounted with a sealing plug (34), and the sealing plug (34) is located directly below the liquid inlet cylinder (33).

4. A method for snow and dust removal for a new energy photovoltaic power generation device, the method using the new energy photovoltaic power generation device with automatic dust and snow removal according to claim 1, characterized in that: The following steps are involved: A1. When the photosensitive surface of the photovoltaic panel needs to be cleaned, the guide vane (26) rotates to draw out the rainwater in the storage box (2) and discharge it from the outer wall of the sliding beam (4); A2. Then, the driving motor (3) is used to control the rotation of the transmission screw, thereby driving the sliding block (6) and the sliding beam (4) to slide, and the cleaning strip (9) is used to scrape and clean the photosensitive surface of the photovoltaic panel; A3. In rainy weather, rainwater falls on the outer wall of the filter layer (5), then seeps into the interior of the liquid inlet hopper (20), and enters the inner cavity of the storage box (2) through the liquid inlet cylinder (33); A4. In sunny weather, by adjusting the reciprocating sliding of the control plug (22), rainwater in the inner cavity of the storage box (2) is controlled to enter one side of the heat absorbing plate (19), and the rainwater is sterilized by light.
