Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation equipment, and particularly relates to a high-efficiency dust removal mechanism for a photovoltaic power generation panel. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy, usually composed of many photovoltaic cells. Its working principle is to use the photoelectric effect of semiconductor materials. When light shines on the surface of the cell on the reaction plate, it will excite electrons to generate current. Photovoltaic panels have the advantages of environmental protection, renewable, and noise-free, and are widely used in solar power generation systems and other fields.

[0003] When used in some dusty and windy environments, the reaction panel is easily covered with a thin layer of dust or fine sand, which affects the photovoltaic efficiency of the photovoltaic panel. At present, there is a structure in the prior art that uses jet blowing to blow away the dust and dust accumulated on the photovoltaic panel, but in actual use, natural wind may interfere with the dust removal effect, especially when the nozzle direction of the jet dust removal structure is opposite to the natural wind direction, the ejected gas flow rate will be completely or partially offset by the natural wind, and when blowing dust against the wind, the blown dust may be brought back to the panel by the natural wind, and the actual dust removal effect is not good. Utility Model Content

[0004] The purpose of the utility model is to address the above problems existing in the prior art and to propose a high-efficiency dust removal mechanism for photovoltaic panels.

[0005] In order to realize the innovation purpose of the utility model, the following technical scheme can be adopted: an efficient dust removal mechanism for photovoltaic power generation panels, comprising a mounting frame and a rectangular photovoltaic panel fixed on the mounting frame, and a wind direction detection component, the mounting frame is provided with at least four groups of jet structures respectively located on the outside of the four corners of the photovoltaic panel, the nozzles of the jet structures are directed toward the photovoltaic panel, and a steering drive structure is provided between the nozzles and the mounting frame; the wind direction detection component and the jet structure are respectively electrically connected to a control panel, and the control panel starts working by controlling the jet structure in the downwind direction through real-time wind direction.

[0006] The rectangular photovoltaic panel of the utility model is arranged on a mounting frame, and jet structures are arranged at the four corners of the photovoltaic panel. The nozzles of each jet structure face the photovoltaic panel, and are used to blow away the accumulated dust on the photovoltaic panel by spraying high-pressure gas, so as to improve the photovoltaic efficiency. The jet structure and the control panel are electrically connected and controlled by the control panel. However, in actual use, the wind direction in nature is uncertain, and the jet against the wind cannot achieve the expected dust removal effect. Therefore, the utility model also provides a wind direction detection component for real-time detection of the wind direction, and transmits the wind direction data to the electrically connected control panel. The control panel controls the nozzle in the downwind direction to start working according to the actual wind direction.

[0012] The height of the nozzle is adapted to the surface of the photovoltaic panel to ensure that the high-pressure gas output by the nozzle effectively acts on the panel surface to achieve a good dust blowing effect.

[0038] Specifically, the rectangular photovoltaic panel 11 of the utility model is arranged on the mounting frame 1, and the four corners of the photovoltaic panel 11 are provided with jet structures 3, and the nozzles 31 of each jet structure 3 are facing the photovoltaic panel 11, and the jet structure 3 is electrically connected to the control panel and is controlled by the control panel. In addition, the utility model is also provided with a wind direction detection component 2, which is used to detect the wind direction in real time and transmit the wind direction data to the electrically connected control panel. The control panel controls the nozzle 31 in the downwind direction to start working according to the actual wind direction. With the assistance of natural wind force, it has a more efficient dust blowing effect, and the blown dust can be carried away by the wind.

[0039] like Figure 2 , 4 As shown, the jet structure 3 includes a nozzle 31 and a bracket 32. The nozzle 31 is fixed on the bracket 32 ​​and connected to the high-pressure gas generating device. The bracket 32 ​​is rotatably connected to the mounting frame 1. A padding block 33 is fixed on the mounting frame 1. A plane bearing 39 is provided between the padding block 33 and the bracket 32. A first rotating shaft 34 is vertically fixed to the upper end of the padding block 33. The bracket 32 ​​is rotatably connected to the first rotating shaft 34 through a first through hole 35. The first through hole 35 is vertically opened on the bracket 32. A first pin hole 36 is horizontally opened on the upper end of the first rotating shaft 34. A first pin 37 is inserted into the first pin hole 36. The height of the nozzle 31 is higher than the surface of the photovoltaic panel 11, and the nozzle 31 is inclined toward the surface of the photovoltaic panel 11. An inclination adjustment structure 5 is provided between the nozzle 31 and the bracket 32. The inclination adjustment structure 5 includes a clamping member 51 arranged on the bracket 32.

The mounting screw 52 is meshed with a locking nut 54.

[0040] Specifically, the nozzle 31 is rotatably connected to the mounting frame 1 through the bracket 32. The nozzle 31 can rotate in a certain direction to increase the range of the jet. Since the jet structure 3 is arranged at the four corners, it only needs to rotate 90 degrees to achieve full coverage of the effective area. In this embodiment, the bracket 32 ​​is a U-shaped member. A padding block 33 is provided between the bracket 32 ​​and the mounting frame 1. The height of the padding block 33 can be selected according to actual needs to adapt to photovoltaic panels 11 of different thicknesses. A first rotating shaft 34 is erected on the padding block 33. The first through hole 35 of the bracket 32 ​​is sleeved on the first rotating shaft 34 to achieve a rotating connection. A first pin 37 is inserted in the first pin hole 36 at the upper end of the first rotating shaft 34 for limiting the position to prevent the bracket 32 ​​from falling out from the upper end. The rotating connection and vertical limiting are both detachable connection structures, which are easy to disassemble and assemble. The height of the nozzle 31 is adapted to the surface of the photovoltaic panel 11 to ensure that the high-pressure gas output by the nozzle 31 effectively acts on the surface of the panel to achieve a good dust blowing effect. When the nozzle 31 is set higher, the nozzle 31 can be set to tilt downward appropriately so that the nozzle 31 faces the surface of the panel to achieve a good dust removal effect. The clamp ring 53 of the clamp member 51 is fixedly connected to the nozzle 31 by tightening. The mounting screw 52 is fixed on the clamp ring 53. The mounting screw 52 is inserted into the clamp mounting hole 38 and can rotate. The effect of controlling the inclination angle of the nozzle 31 is achieved by rotating at different angles. After adjusting to the appropriate position, the locking nut 54 is tightened and fixed. The fixation is a detachable connection, which is convenient for disassembly and rotation adjustment. The plane bearing 39 is used to reduce the rotation resistance between the pad block 33 and the bracket 32, and at the same time, it can prevent the interface between the pad block 33 and the bracket 32 ​​from being worn.

[0041] like Figure 1 , 2 As shown, the steering drive structure 6 includes a linkage assembly 61 and a drive assembly 62. The linkage assembly 61 is arranged between adjacent jet structures 3, and the drive assembly 62 and the linkage assembly 61 are connected in cooperation. The linkage assembly 61 includes a linkage rod 63, and second through holes 64 are respectively opened at both ends of the linkage rod 63. A second rotating shaft 40 is vertically fixed on the bracket 32, and the second rotating shaft 40 is inserted in the second through hole 64. A second pin hole 41 is horizontally arranged on the upper end of the second rotating shaft 40, and a second pin 42 is inserted in the second pin hole 41. The drive assembly 62 includes a telescopic cylinder 65, which is arranged on the mounting frame 1, and the output end is synchronously connected with one of the linkage rods 63. The telescopic cylinder 65 is hingedly connected to the mounting frame 1, and a connecting rod 66 is vertically fixed on the output end, and the connecting rod 66 is inserted in the third through hole 67 of the linkage rod 63, and the third through hole 67 is vertically arranged on the linkage rod 63.

[0042] Specifically, the linkage assembly 61 is used to synchronize the rotation of each jet structure 3. The driving assembly 62 only needs to be connected with one of the linkage assemblies 61 to achieve the effect of controlling the rotation of all jet structures 3, thereby reducing the cost of the driver. The two ends of the linkage rod 63 are respectively connected to the second rotating shaft 40 on the adjacent bracket 32 ​​through the second through hole 64, which is used to synchronize the rotation of the adjacent bracket 32. Of course, the second rotating shaft 40 and the first rotating shaft 34 are no longer on the same axis. The upper end of the second rotating shaft 40 is provided with a second pin hole 41 and a second latch 42, which are used to prevent the linkage rod 63 from escaping from the upper end of the second rotating shaft 40.

By telescoping the output end, the linkage rod 63 is controlled to move, and the linkage rod 63 drives the mounting frame 1 to rotate, thereby achieving the effect of controlling the direction of the jet structure 3. The telescopic cylinder 65 is hingedly connected to the mounting frame 1 and can rotate freely on the plane of the mounting frame 1. At the same time, the connecting rod 66 at the output end is vertically arranged and inserted into the third through hole 67 of the linkage rod 63. The two are also rotatably connected to adapt to the lateral displacement generated when the output end drives the linkage rod 63 to move along the length direction.

[0043] Specific working principle: The wind direction detection component 2 detects the wind direction data in real time and transmits the data to the control panel. When dust blowing is needed, the control panel starts the nozzle 31 in the direction of the wind according to the real-time wind direction, and at the same time starts the reciprocating telescopic action of the telescopic cylinder 65, so that the nozzle 31 swings back and forth, and with the help of natural wind, the dust on the reaction plate surface is blown away.
