Description

Technical Field

[0001] This invention relates to the field of solar power generation technology, and more specifically to a solar power generation device designed for harsh high-altitude environments. Background Technology

[0002] With the continuous development of solar power generation technology, solar power generation devices are widely used in various environmental conditions, especially in high-altitude areas. These areas offer favorable solar energy resources due to long hours of sunshine and high solar radiation intensity, making the construction of solar power generation devices in high-altitude regions a promising prospect. However, high-altitude areas are often accompanied by harsh climatic environments such as low temperatures, strong winds, frequent snowfall, and dry, dusty air, which can easily adversely affect the normal operation of solar power generation devices.

[0003] In practical use, the surface of photovoltaic panels in solar power generation devices is prone to snowfall and dust accumulation. When the surface of the photovoltaic panels is covered with snow or dust, it blocks sunlight, reducing the panel's efficiency in absorbing solar energy and thus significantly decreasing power generation efficiency. In high-altitude areas, snowfall often does not melt naturally, and strong winds continuously bring new dust, making the problem of surface contamination of photovoltaic panels even more pronounced.

[0004] In existing technologies, most solar power generation devices rely primarily on manual, periodic cleaning of the photovoltaic panel surface to remove snow and dust. However, high-altitude areas typically have complex terrain, cold climates, and are difficult for personnel to access, making manual maintenance not only labor-intensive but also costly. Furthermore, in environments with frequent snowfall or strong winds, more frequent cleaning operations are required, further increasing maintenance difficulty and time costs, making it difficult to meet the requirements for long-term stable operation.

[0005] Existing technologies also have devices for automatically cleaning photovoltaic panels, but they can only clean one photovoltaic panel at a time. To clean multiple panels, multiple cleaning devices would be required. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention aims to provide a solar power generation device designed for harsh high-altitude environments. To solve these problems, this invention employs the following technical solution: A solar power generation device designed for harsh high-altitude environments includes a support frame, a liquid collection column, and photovoltaic panels. The support frame and the liquid collection column are both fixed to the ground. Two or more photovoltaic panels are connected between the support frame and the photovoltaic panels. A water collection tank is provided on the liquid collection column. A slide rail is fixed to the support frame. A winding device is slidably connected to the slide rail. A rope is movably connected to the winding device. An integrated snow melting and dust removal mechanism is connected to the rope. A heating roller device and a dust removal component are connected to the integrated snow melting and dust removal mechanism. A dust removal component replacement mechanism is connected to the support frame.

[0007] Optionally, the integrated snow melting and dust removal mechanism includes an operation box, on which a rotating rod is rotatably connected. The heating roller device is fixed to one end of the rotating rod, and an active magnetic strip is fixed to the other end of the rotating rod. Two limiting strips are fixed to the active magnetic strip. A dust removal component is connected to an active magnetic strip. The dust removal component includes a cleaning strip and an iron sheet that are fixedly connected to each other. The cleaning strip is magnetically connected to the active magnetic strip. A push plate is slidably connected to the bracket, and the push plate is connected to the bracket via an elastic element.

[0008] Optionally, the cleaning component replacement mechanism includes a storage box, which has a storage cavity, a plate cavity, and a drop channel. The storage cavity and the drop channel are connected to the plate cavity, and the drop channel is connected to the bottom wall of the storage box. Two or more cleaning components are stacked in the storage cavity. A wedge plate is slidably connected to the inner wall of the plate cavity. The wedge plate is connected to the inner wall of the plate cavity through an elastic element. A bent rod and a T-shaped rod are slidably connected to the storage box. A support plate is fixed to the bent rod and extends into the drop channel. The support plate is connected to a bracket through an elastic element. The lower end of the bent rod extends to the outside of the storage box and a passive magnetic strip is fixed to the lower end of the bent rod. The horizontal section of the T-shaped rod extends to the bottom of the storage box, and the upper end of the vertical section of the T-shaped rod extends into the plate cavity. A push wheel is rotatably connected to the upper end of the vertical section of the T-shaped rod.

[0009] Optionally, the winding device is equipped with an electric slider, and the winding device is slidably connected to the slide rail via the electric slider.

[0010] Optionally, the control box is equipped with a brake motor mechanism, which is connected to the rotating rod.

[0011] Optionally, the photovoltaic panel is tilted.

[0012] Optionally, the storage box is fixed to the bracket by a connecting rod.

[0013] Optionally, the distance between the two limiting strips is greater than the width of the cleaning strip.

[0014] Optionally, the bottom wall of the operating box is provided with an extension seat.

[0015] Optionally, the bracket may be made of stainless steel.

[0016] The present invention has the following beneficial effects: This invention utilizes a cleaning strip that moves back and forth along the photovoltaic panel to wipe and clean the cells. Simultaneously, when the cleaning strip reaches the liquid collection column, it picks up water from the collection tank within the column to moisten the panel, improving the removal of dust and other deposits from the photovoltaic panel surface. Furthermore, by incorporating a heating roller device on the control box, the heating roller melts snow accumulated on the photovoltaic panel during its movement, thus achieving automatic cleaning of snow and dust. This avoids the high labor intensity and maintenance costs associated with manual cleaning. A single integrated snow melting and dust removal mechanism can clean multiple photovoltaic panels, reducing the number of cleaning components, improving the overall operating efficiency and economy of the device, and enhancing its applicability in harsh high-altitude environments. By setting a storage box on the bracket, the cleaning strip can be automatically detached and replaced when the integrated snow melting and dust removal mechanism switches cleaning modes, thereby realizing the automatic replacement function of the cleaning strip and reducing the frequency of manual replacement of cleaning parts.

[0023] Example 1: like Figures 1-6As shown, a solar power generation device for high-altitude and harsh environments includes a support frame 1, a liquid collection column 3, and photovoltaic panels 7. The support frame 1 and the liquid collection column 3 are both fixed to the ground. Two or more photovoltaic panels 7 are connected between the support frame 1 and the photovoltaic panels 7. A water collection trough is provided on the liquid collection column 3. A slide rail 2 is fixed to the support frame 1. A winding device 4 is slidably connected to the slide rail 2. A rope 5 is movably connected to the winding device 4. A snow melting and dust removal integrated mechanism is connected to the rope 5. A heating roller device 8 and a dust removal component are connected to the snow melting and dust removal integrated mechanism. A dust removal component replacement mechanism is connected to the support frame 1.

[0024] Through the above structural design, the integrated snow melting and dust removal mechanism can move on the surface of the photovoltaic panel 7 to automatically melt snow and remove dust from the photovoltaic panel 7, thereby reducing manual maintenance and improving the operational stability of the device in harsh high-altitude environments.

[0025] Specifically, the integrated snow melting and dust removal mechanism includes an operation box 6, a rotating rod 9 rotatably connected to the operation box 6, a heating roller device 8 fixedly connected to one end of the rotating rod 9, an active magnetic strip 10 fixedly connected to the other end of the rotating rod 9, and two limiting strips 25 fixedly connected to the active magnetic strip 10. The rotation of the rotating rod 9 enables the switching of the working state between the heating roller device 8 and the dust removal component, allowing the device to perform both snow melting and dust removal operations.

[0026] A dust removal component is connected to the active magnetic strip 10. The dust removal component includes a cleaning strip 15 and an iron sheet 16 that are fixedly connected to each other. The cleaning strip 15 is magnetically connected to the active magnetic strip 10. The magnetic connection between the active magnetic strip 10 and the iron plate 16 enables the cleaning components to be quickly installed and disassembled, facilitating subsequent automatic replacement.

[0027] A push plate 27 is slidably connected to the bracket 1, and the push plate 27 is connected to the bracket 1 through an elastic element 26.

[0028] To achieve automatic replacement, the cleaning component replacement mechanism includes a storage box 11. The storage box 11 has a storage cavity 12, a plate cavity 13, and a discharge channel 14. The storage cavity 12 and the discharge channel 14 are respectively connected to the plate cavity 13. The discharge channel 14 is connected to the bottom wall of the storage box 11. Two or more cleaning components are stacked in the storage cavity 12. A wedge plate 17 is slidably connected to the inner wall of the plate cavity 13. The wedge plate 17 is connected to the inner wall of the plate cavity 13 via an elastic element 18. The upper part is connected by a bending rod 20 and a T-shaped rod 23. A support plate 19 is fixedly connected to the bending rod 20. The support plate 19 extends into the drop channel 14. The support plate 19 is connected to the bracket 1 through an elastic element 22. The lower end of the bending rod 20 extends to the outside of the storage box 11. A passive magnetic strip 21 is fixedly connected to the lower end of the bending rod 20. The horizontal section of the T-shaped rod 23 extends below the storage box 11. The upper end of the vertical section of the T-shaped rod 23 extends into the plate cavity 13. A push wheel 24 is rotatably connected to the upper end of the vertical section of the T-shaped rod 23.

[0029] In order to realize the electric sliding function of the winding device 4, the winding device 4 is provided with an electric slider, and the winding device 4 is slidably connected to the slide rail 2 through the electric slider.

[0030] To enable the electric drive of the rotating rod 9, a brake motor mechanism is provided on the control box 6, and the brake motor mechanism is connected to the rotating rod 9. The brake motor mechanism can maintain the current angle of the rotating rod 9 after it has been controlled to rotate.

[0031] To improve the photoelectric conversion efficiency and ensure the smooth operation of the integrated snow melting and dust removal mechanism, the photovoltaic panel 7 is tilted.

[0032] The storage box 11 is connected in such a way that it is fixed to the bracket 1 by a connecting rod.

[0033] It is worth noting that the distance between the two limiting strips 25 is greater than the width of the cleaning strip 15.

[0034] To provide support, the bottom wall of the control box 6 is provided with an extension seat. The extension seat can provide temporary support for the control box 6 when the rotating rod 9 rotates.

[0035] To improve transmission stability, the rope 5 is provided with two ropes. The double rope structure can evenly distribute the force, thereby improving the stability of the integrated snow melting and dust removal mechanism during movement.

[0036] To improve structural rigidity, the support frame 1 is made of stainless steel. By using stainless steel to manufacture the support frame 1, the device can withstand harsh environments such as low temperatures and strong winds in high-altitude areas.

[0037] Working principle: In the initial state, the pallet 19 and the side wall of the falling channel 14 abut against each other, the pusher 24 and the bottom wall of the plate cavity 13 abut against each other, the active magnetic strip 10 faces downward, the heating roller device 8 faces upward, the operation box 6 and the push plate 27 abut against each other, the elastic element 3 26 is compressed, the cleaning strip 15 and the top wall of the bracket 1 abut against each other, the bottom wall of the extension seat on the operation box 6 does not abut against the bottom wall of the bracket 1, and the water collection tank on the liquid collection column 3 is filled with water after the snow melts.

[0038] When it is necessary to clean the photovoltaic panel 7, the control winding device 4 releases the rope 5, the elastic element 26 gradually extends, driving the push plate 27 to push the operation box 6. The operation box 6 moves towards the photovoltaic panel 7, and the cleaning strip 15 on the operation box 6 comes into contact with the photovoltaic panel 7. The rope 5 continues to be released, and the operation box 6 gradually moves down along the photovoltaic panel 7, so that the cleaning strip 15 wipes and cleans the cells on the photovoltaic panel 7.

[0039] When the cleaning strip 15 moves down into the water collection tank inside the liquid collection column 3, the rope 5 stops being released. The cleaning strip 15 will be wetted by the water in the liquid collection column 3, causing the electric slider to move a certain distance along the slide rail 2, thereby causing the winding device 4 to move along the slide rail 2, which in turn drives the cleaning strip 15 to move. The winding device 4 controls the rope 5 to retract, and the cleaning strip 15 moves up along the photovoltaic panel 7 to clean the uncleaned cells on the photovoltaic panel 7.

[0040] After the cleaning strip 15 disengages from the solar cell, it does not move onto the bracket 1. The rope 5 stops retracting, and the winding device 4 moves a distance along the slide rail 2. The winding device 4 then releases the rope 5, and the cleaning strip 15 moves down to clean the uncleaned solar cells on the photovoltaic panel 7. This process is repeated to clean all the photovoltaic panels 7. The two limit strips 25 limit the cleaning strip 15 to prevent it from disengaging from the active magnetic strip 10.

[0041] After the dust removal is completed, the winding device 4 and the operation box 6 return to their initial positions. At this time, the cleaning strip 15 abuts against the top wall of the bracket 1, and the brake motor mechanism controls the rotating rod 9 to rotate about 180 degrees. During this process, the cleaning strip 15 disengages from the bracket 1, and the bottom wall of the extension seat on the operation box 6 abuts against the bracket 1 for temporary support. After the heating roller device 8 pushes away the passive magnetic strip 21, the passive magnetic strip 21 resets under the elastic force of the elastic element 22. The cleaning strip 15 rotates to abut against the bottom wall of the horizontal section of the T-bar 23. The cleaning strip 15 pushes the T-bar 23 upward, and the push wheel 24 pushes the inclined surface of the wedge plate 17, thereby causing the wedge plate 17 to move against the elastic force of the elastic element 18. The wedge plate 17 pushes the lowest cleaning strip 15 in the storage strip cavity 12 to the left, and the cleaning strip 15 falls onto the top wall of the support plate 19. The top wall of the wedge plate 17 supports the other cleaning strips 15. When the T-bar 23 moves to the upper limit position, the T-bar 23 can no longer... As the rod moves upward, the rotating rod 9 continues to rotate, and the T-shaped rod 23 pushes the cleaning strip 15 to detach it from the active magnetic strip 10. The iron piece 16 is released from its magnetic connection with the active magnetic strip 10. When the active magnetic strip 10 rotates about 180 degrees, the roller on the heating roller device 8 and the top wall of the bracket 1 come into contact, and the bottom wall of the extension seat on the operating box 6 and the bracket 1 disengage. The active magnetic strip 10 rotates to the side of the passive magnetic strip 21. The active magnetic strip 10 is located below the falling channel 14. The active magnetic strip 10 generates a magnetic repulsion force on the passive magnetic strip 21. The passive magnetic strip 21 overcomes the elastic force of the elastic element 22 and moves away from the active magnetic strip 10. The tray 19 moves away from the falling channel 14, thereby releasing the support for the cleaning strip 15 in the falling channel 14. The cleaning strip 15 falls onto the active magnetic strip 10, and the active magnetic strip 10 magnetically attracts and connects to the iron piece 16 on the cleaning strip 15, thus completing the replacement of the cleaning strip 15. At this time, the heating roller device 8 faces downward.

[0042] When snow melting is needed, the above method is used to control the operation box 6 to move on the photovoltaic panel 7, and control the roller on the heating roller device 8 to heat up. When the roller on the heating roller device 8 rolls, it melts the snow on the photovoltaic panel 7 into water. The water flows into the water collection tank in the liquid collection column 3 for collection and replenishment. The roller rolling design on the heating roller device 8 can greatly reduce the scratching of the solar cells on the photovoltaic panel 7 and can also adapt to uneven snow piles.

[0043] When the dust removal operation is needed again, you can refer to the above content to implement it, and it will not be described again here.

[0044] The beneficial effects of this invention are as follows: This invention features a slide rail 2 mounted on a support 1, with a winding device 4 slidably connected to the slide rail 2. The winding device 4 controls the rope 5 to move the operating box 6 across the surface of the photovoltaic panel 7, allowing the cleaning strip 15 to reciprocate along the photovoltaic panel 7, wiping and cleaning the solar cells. Simultaneously, when the cleaning strip 15 reaches the liquid collection column 3, it picks up water from the water collection tank within the column, further improving the removal of dust and deposits from the photovoltaic panel 7. Furthermore, a heating roller device 8 mounted on the operating box 6 heats and melts the snow on the photovoltaic panel 7 during movement, reducing scratches on the solar cells through rolling contact. This achieves automatic cleaning of snow and dust from the photovoltaic panel 7, avoiding the high labor intensity and maintenance costs associated with manual cleaning. A single integrated snow melting and dust removal mechanism can clean multiple photovoltaic panels 7, reducing the number of cleaning components, improving the overall operating efficiency and economy of the device, and enhancing its applicability in harsh high-altitude environments. By setting a storage box 11 on the bracket 1, and through the cooperation of the wedge plate 17, T-bar 23, push wheel 24, tray 19, and active magnetic strip 10 and passive magnetic strip 21, the cleaning strip 15 can automatically detach and be replaced when the integrated snow melting and dust removal mechanism switches cleaning modes, thereby realizing the automatic replacement function of the cleaning strip 15 and reducing the frequency of manual replacement of cleaning parts.

[0045] Example 2: In this embodiment, the solar power generation device described in Embodiment 1 is installed in the Tibetan Plateau region (altitude approximately 4000 meters, annual snowfall exceeding 1500 mm) with high altitude and extreme climate conditions. By utilizing automatic snow melting and dust removal functions, the surface of the photovoltaic panel is effectively kept clean, thereby improving its power generation efficiency.

[0046] The installation location receives approximately 2,800 hours of sunshine per year, with an average solar radiation intensity of 5.5 kWh / m² / d.

[0047] The photovoltaic panel 7 is tilted at an angle of 45°.

[0048] The heating roller device 8 can heat and melt snow, with a maximum melting depth of 5 centimeters.
