Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation installation cleaning, in particular to a photovoltaic power generation installation cleaning device. Background Art

[0002] With the acceleration of global energy transformation and the deepening of sustainable development strategies, the development and application of solar energy as a clean and renewable energy resource has attracted increasing global attention. Photovoltaic power generation technology, as the core means of converting solar energy into electrical energy, has been widely infiltrated into various application scenarios, covering from large-scale ground photovoltaic power stations to microscopic building integrated systems, demonstrating the broad potential of solar energy utilization. Under this trend, developing unconventional spaces for the deployment of photovoltaic power generation systems has become an important innovation direction for improving the utilization rate of solar energy resources and promoting energy conservation and emission reduction.

[0003] However, this process is also accompanied by special challenges to the design and implementation of photovoltaic power generation systems in specific environments, especially when considering installation in unique locations such as the top of coal bunkers. Coal bunkers, as key infrastructure for coal storage, are mostly located in open areas. The top structure not only needs to withstand the impact of high wind speeds, but is also often designed with an arc to ensure structural stability and coal storage needs. These specific conditions put forward higher standards for the stable operation, structural safety and adaptability of photovoltaic power generation systems.

[0004] Traditional photovoltaic power generation systems mostly rely on fixed installation modes and are directly installed on flat surfaces. This is not enough when facing the curved structure on the top of the coal bunker and the dynamic wind environment. Fixed installation is not only difficult to effectively meet the needs of curved surface installation, but may also reduce power generation efficiency due to wind-induced vibration, and even cause physical damage to photovoltaic modules, shortening the life of the equipment. At the same time, the fixed tilt angle design cannot automatically adjust according to seasonal changes and the solar altitude angle, further limiting the power generation efficiency of the system.

[0005] In addition, once the photovoltaic power generation device on the top of the coal bunker is installed, its maintenance and cleaning work will become more difficult, and long-term dust accumulation will inevitably affect the power generation efficiency, highlighting the operation and maintenance difficulties faced in implementing photovoltaic power generation projects in such special environments.

DETAILED DESCRIPTION

[0027] like Figures 1 to 3 As shown, the photovoltaic panel 1 is arranged on the arc-shaped silo roof 20 through the mounting frame 3, and the bottom of the mounting frame 3 is arranged on the surface of the arc-shaped silo roof 20 through a plurality of sleeper seats 9, the lower surfaces of the plurality of sleeper seats 9 are in contact with the surface of the arc-shaped silo roof 20, and the upper surfaces of the plurality of sleeper seats 9 are on the same horizontal plane, and an angle adjustment device is further provided at one end of the mounting frame 3, and the angle adjustment device is connected to the photovoltaic panel 1;

[0028] A cleaning device 5 is clamped at one end of the photovoltaic panel 1. The cleaning device 5 includes a square tube 501. The square tube 501 is provided with multiple water spray outlets 502. A plurality of clamping seats 503 are provided below the square tube 501. The clamping seats 503 are clamped on the side of the photovoltaic panel 1. The square tube 501 is connected to the water tank 19 through a water pump 18.

[0029] The photovoltaic panel 1 is firmly mounted on the curved warehouse roof 20 through the mounting frame 3. This design cleverly uses the mounting frame to adapt to the non-planar structure to ensure that the photovoltaic panel can be firmly installed. The multiple sleeper seats 9 at the bottom of the mounting frame are close to the warehouse roof surface. They not only provide the necessary support, but also increase the stability and uniform force of the overall structure by being uniformly adjusted to the same horizontal plane, which is particularly suitable for the installation requirements of curved surfaces.

[0030] One end of the mounting frame is equipped with an angle adjustment device, which allows the photovoltaic panel to adjust in time according to the changes in the incident angle of sunlight, thereby maximizing the absorption efficiency. The angle adjustment mechanism is crucial to improving the power generation efficiency of all weather and all seasons, ensuring that the photovoltaic system can flexibly adapt to changes in lighting conditions.

[0031] The cleaning device 5 connected to one end of the photovoltaic panel includes a square tube 501 and is equipped with multiple water spray ports 502, which are connected to the water tank 19 through a water pump 18 to form an automated cleaning system. The system uses water flow to regularly rinse the surface of the photovoltaic panel, effectively remove dust and dirt, maintain the high light transmittance of the photovoltaic panel, and ensure that the power generation efficiency is not affected. The multiple holders 503 under the square tube are designed to be fixed to the side of the photovoltaic panel, ensuring the stability of the cleaning device during operation.

[0032] In the preferred embodiment, the bottom of the mounting frame 3 is connected to a bottom plate 12, which is arranged on the upper surface of a plurality of sleeper seats 9, and is further provided with bolts 10, which pass through the bottom plate 12 and the sleeper seats 9 and are fixed to the arc-shaped warehouse roof 20. A spring 11 is provided between the upper end of the bolt 10 and the bottom plate 12, and the spring 11 is sleeved on the bolt 10.

[0033] The bottom of the mounting frame 3 is connected to a plurality of sleeper seats 9 via a base plate 12, and the base plate is located on the upper surface of the sleeper seats. This design not only ensures a firm connection between the mounting frame and the arc-shaped silo roof, but also directly fixes the mounting frame to the silo roof surface by penetrating the base plate and the sleeper seats via bolts 10, further enhancing the stability and reliability of the overall structure.

[0034] A spring 11 is arranged between the bolt 10 and the bottom plate 12, and the spring is sheathed on the bolt. This design constitutes a simple but highly effective shock absorption system. When encountering external dynamic loads such as strong winds, the spring can absorb and disperse the vibration and stress caused by the wind, avoiding direct transmission to the photovoltaic panel, thereby reducing equipment vibration and potential physical damage caused by wind, protecting the photovoltaic panel from damage and extending its service life.

[0035] The combination of the sleeper seat layout and the use of springs together builds a natural wind buffer area. The sleeper seat itself can disperse the wind force and reduce the area where the wind directly hits the photovoltaic panels; while the springs further absorb the remaining wind pressure. The two work together to effectively alleviate the direct impact of wind on the photovoltaic panels and the entire system, greatly improving the operational stability and safety in high wind speed environments.

[0036] In the preferred embodiment, the structure of the angle adjustment device is as follows: one end of the photovoltaic panel 1 is hinged to one side of the mounting frame 3, a motor 13 is provided at the middle position of the other side of the mounting frame 3, the output end of the motor 13 is connected to the screw 15, the screw 15 is hinged to the third hinge seat 14 at the middle position of the mounting frame 3, the screw 15 is hinged to the third hinge seat 14, the other end of the photovoltaic panel 1 is provided with a second hinge seat 4, the second hinge seat 4 is hinged with a screw sleeve 16, and the screw sleeve 16 is threadedly connected to the screw 15;

[0037] The motor 13 drives the screw rod 15 to drive the screw sleeve 16 to extend and retract, thereby adjusting the tilt angle of the photovoltaic panel 1 .

[0038] The motor 13 drives the screw 15 to drive the screw sleeve 16 to extend and retract, and the angle of the solar panel can be adjusted as needed to adapt to the changes in the angle of sunlight in different seasons and different time periods, thereby improving the power generation efficiency of the solar photovoltaic module. When there is a strong wind, the photovoltaic panel 1 is leveled to play a windproof role.

[0039] One end of the photovoltaic panel 1 is connected to the mounting frame by a hinge, and a motor 13 is built in the middle of the other side of the mounting frame. The output shaft of the motor is connected to a screw rod 15, and one end of the screw rod is connected to the third hinge seat 14 on the mounting frame to form a rotatable hinge point. At the same time, the other end of the photovoltaic panel is installed through the second hinge seat 4, and a screw sleeve 16 is set on the hinge seat. The screw sleeve 16 and the screw rod 15 are matched by threads and can be telescopically moved with the rotation of the screw rod.

[0040] The operation of the motor 13 becomes the core driving force for adjusting the tilt angle of the photovoltaic panel 1. When the motor 13 starts and rotates the screw 15, the screw sleeve 16 slides up and down along the screw 15, driving the photovoltaic panel 1 to rotate around the hinge point, thereby achieving precise adjustment of the tilt angle of the photovoltaic panel. This design enables the photovoltaic panel to automatically adjust to the optimal tilt angle according to the seasonal changes and the solar altitude angle at different times of the day, maximizing the capture and conversion efficiency of sunlight and significantly improving the power generation efficiency.

[0041] It is worth mentioning that in windy weather, the system can adjust the photovoltaic panel 1 to a nearly horizontal position through motor control, effectively reducing wind resistance and the impact of wind on the photovoltaic panel 1, thus protecting the equipment and preventing damage. This ability to actively adapt to environmental changes not only ensures the safe and stable operation of the system, but also extends the service life of the photovoltaic components.

[0042] In the preferred embodiment, the water spray port 502 has a trumpet-shaped opening, the holder 503 has a U-shaped structure, and the holder 503 is clamped on the edge of the second hinge seat 4 of the photovoltaic panel 1 on one side.

[0043] The water spray port 502 in the cleaning device adopts a trumpet-shaped opening design, which is conducive to the diffusion of the water beam, so that the sprayed water covers a wider area, and can form a uniform water film when it contacts the surface of the photovoltaic panel, effectively removing dust and dirt on the surface. Compared with a small direct nozzle, the trumpet-shaped nozzle can better meet the needs of large-area cleaning without increasing the water pressure, reducing the risk of impact damage to the surface of the photovoltaic panel.

[0044] The holder 503 is designed as a U-shaped structure, which is convenient for firmly snapping into the edge of the second hinged seat 4 of the photovoltaic panel, ensuring that the cleaning device is firmly fixed during the cleaning process. It can remain stable even during water spraying operations and will not shift due to water pressure or equipment vibration, thereby ensuring the accuracy and safety of the cleaning work.

[0045] The water nozzle uses a large amount of water to flush, and can effectively remove dust on the surface of the photovoltaic panel without high pressure. This method is gentle and efficient, which not only protects the surface of the photovoltaic panel from potential damage caused by high-pressure water impact, but also ensures the cleaning effect. In addition, during the cleaning process, an appropriate amount of detergent can be flexibly added to the water, and the chemical action can be used to further improve the cleaning efficiency, which has a better removal effect on stubborn stains, ensures the light transmittance of the photovoltaic panel surface, and maintains its maximum power generation efficiency.

[0046] In a preferred embodiment, a locking screw 504 is further provided at the bottom of the holder 503 , and the locking screw 504 passes through the lower plate of the holder 503 and abuts against the photovoltaic panel 1 , and the locking screw 504 is threadedly connected to the lower plate of the holder 503 .

[0047] A locking screw 504 is added to the bottom of each holder 503, and the screw is inserted through the lower plate of the holder and directly contacts the surface of the photovoltaic panel. This arrangement allows the screw to not only fit the edge of the photovoltaic panel, but also to tightly engage with the lower plate of the holder through a threaded connection to form a stable mechanical support structure.

[0048] In the preferred embodiment, a water collection tank 6 is further provided at one end of the photovoltaic panel 1, and the water collection tank 6 is arranged at a position opposite to the cleaning device 5, and the water collection tank 6 is arranged on the mounting frame 3 through a bracket 7. The lower end of the water collection tank 6 is connected to a drain pipe, and the bent end of the drain pipe is fixed to the arc-shaped silo roof 20 through a pipe bracket 8, and the drain pipe is connected to the wastewater tank.

[0049] A water collection tank 6 is provided at one end of the photovoltaic panel, and its position is specially arranged on the opposite side of the cleaning device 5. Such a layout can effectively collect the water sprayed by the cleaning device.

[0050] The water collection tank 6 is fixed on the mounting frame 3 by the bracket 7, ensuring its stability and reasonable position, so as to facilitate the smooth diversion of the collected water. The lower end of the water collection tank is connected to the drain pipe to form a smooth drainage channel. The bending design of the drain pipe not only adapts to the structure of the arc-shaped silo roof 20, but also is fixed by the pipe bracket 8, which enhances the fixity and prevents displacement or damage in windy weather.

[0051] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
