Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to an angle-adjustable photovoltaic bracket. Background Art

[0002] With the widespread application of solar photovoltaic power generation technology, the number of photovoltaic panels in use is increasing. However, during the long-term use of photovoltaic panels, pollutants such as dust, sand, and bird droppings will gradually accumulate on their surface. These pollutants will block sunlight from reaching the surface of the photovoltaic panels, reducing the power generation efficiency of the photovoltaic panels.

[0003] Photovoltaic panels are installed on site through brackets. Some brackets in the existing technology have a single function and cannot handle dust on the surface of photovoltaic panels. At present, the cleaning of dust on the surface of photovoltaic panels mainly relies on manual regular wiping or high-pressure water gun washing. Manual wiping is not only labor-intensive and inefficient, but also difficult to achieve timely and comprehensive cleaning for large-scale photovoltaic power stations; although high-pressure water gun washing is relatively efficient, it consumes a lot of water resources and is difficult to implement in some areas with scarce water resources.

[0004] Some brackets are equipped with dust cleaning components, but they need to be powered by electricity throughout the process, which is not energy-efficient and cannot fully utilize natural conditions. According to observations, the most serious dust accumulation on the surface of photovoltaic panels occurs during strong winds, so wind power can be used to clean photovoltaic panels, reduce the degree of dust blocking photovoltaic panels during strong winds, and increase power generation. Summary of the invention

[0005] The purpose of the present invention is to provide an angle-adjustable photovoltaic bracket in order to solve the above-mentioned problem, as described below in detail.

An adjustment frame assembly is fixedly connected to the bottom of the mounting frame and is used to adjust the angle and orientation of the photovoltaic panel.

[0008] The cleaning mechanism comprises two fixed plates respectively fixedly connected to both sides of the mounting frame, two rotating shafts are rotatably connected between the two fixed plates, two sprockets are fixedly connected to the rotating shafts, two sprockets located on different rotating shafts and corresponding to each other are connected by chain transmission, the relative positions of the two chains are fixedly connected with connecting heads, and the connecting heads are rotatably connected with fixing pins, the fixing pins are fixedly connected with gears, a fixing tube is fixedly connected between the two fixing pins, a brush is provided on the surface of the fixing tube, a knocking assembly is provided in the fixing tube, and the fixing tube can knock on the surface of the photovoltaic panel through the knocking assembly when rotating, two racks are fixedly connected to the mounting frame, the two gears are respectively adapted to the two racks, and a rubber scraper is fixedly connected between the two chains;

[0009] The rotating shaft is fixedly connected with a wind wheel.

[0010] By using the above-mentioned adjustable angle photovoltaic bracket, the angle of the photovoltaic panel can be adjusted by adjusting the bracket assembly according to the light in the area to maximize its power generation efficiency. When the environmental wind force increases, the dust coverage on the surface of the photovoltaic panel will increase, and the wind force will also drive the cleaning mechanism to clean the dust on the surface of the photovoltaic panel.

[0011] Natural wind can drive the wind wheel, and the wind wheel rotates the shaft. The shaft cooperates with the sprocket, chain, gear and rack to rotate the fixed tube and the brush, and the fixed tube follows the sprocket to move along the length of the photovoltaic panel. The fixed tube cooperates with the brush to loosen the dust covering the surface of the photovoltaic panel, and then the dust on the surface of the photovoltaic panel can be removed by the rubber scraper. While the fixed tube rotates, the knocking component inside it can knock on the surface of the photovoltaic panel, thereby generating vibration, which is conducive to loosening the dust on the surface of the photovoltaic panel.

[0012] Preferably, a motor is fixedly connected to the fixed plate, and an output shaft of the motor is fixedly connected to one end of the two rotating shafts.

[0013] Preferably, a plurality of hollows are provided at the bottom of the mounting frame for heat dissipation of the photovoltaic panel.

[0014] Preferably, a dust sensor is fixedly connected to the cleaning mechanism for detecting dust coverage on the surface of the photovoltaic panel.

[0016] Preferably, a rubber pad is fixedly connected to the bottom of the mounting plate, and a plurality of positioning heads are fixedly connected to the upper end of the support column, and the positioning heads correspond to the rubber pad.

[0017] Preferably, a fixing ring is fixedly connected to the outline of the wind wheel, and a plurality of blades are fixedly connected to the surface of the fixing ring along the radial direction of the wind wheel.

[0018] Preferably, the knocking assembly includes a plurality of movable rods, the movable rods radially penetrate the fixed tube, a spring is sleeved on the surface of the movable rod, and two ends of the spring are fixedly connected to the fixed tube and the movable rods respectively.

[0019] One end of the movable rod passing through the fixed tube is fixedly connected with a rubber head.

[0020] The beneficial effects are:

[0021] The wind wheel can be driven by natural wind, and the wind wheel rotates the rotating shaft. The rotating shaft cooperates with the sprocket, chain, gear and rack to rotate the fixed tube and the brush, and the fixed tube follows the sprocket to move along the length of the photovoltaic panel. The fixed tube cooperates with the brush to loosen the dust covering the surface of the photovoltaic panel, and then the dust on the surface of the photovoltaic panel can be removed by the rubber scraper. While the fixed tube rotates, the knocking component inside it can knock on the surface of the photovoltaic panel, thereby generating vibration, which is conducive to loosening the dust on the surface of the photovoltaic panel. By setting up a cleaning mechanism, the energy consumption of dust cleaning can be saved, and the power generation rate of the photovoltaic panel in windy and sandy weather can be improved.

[0035] The cleaning mechanism 3 includes two fixed plates 15 respectively fixedly connected to both sides of the mounting frame 1, two rotating shafts 16 are rotatably connected between the two fixed plates 15, two sprockets 17 are fixedly connected to the rotating shaft 16, and two corresponding sprockets 17 located on different rotating shafts 16 are connected by a chain 18 for transmission, and the relative positions of the two chains 18 are fixedly connected with connectors, and the connectors are rotatably connected with fixed pins 21, and the fixed pins 21 are fixedly connected with gears 22, and a fixed tube 19 is fixedly connected between the two fixed pins 21, and a brush 30 is arranged on the surface of the fixed tube 19, and a knocking assembly 24 is arranged in the fixed tube 19, and the fixed tube 19 can knock the surface of the photovoltaic panel 4 through the knocking assembly 24 when rotating, and two racks 23 are fixedly connected to the mounting frame 1, and the two gears 22 are respectively adapted to the two racks 23, and a rubber scraper 31 is fixedly connected between the two chains 18;

[0036] The rotating shaft 16 is fixedly connected with a wind wheel 5, and the wind wheel 5 cooperates with natural wind to automatically clean dust on the surface of the photovoltaic panel.

[0037] As an optional implementation, a motor 20 is fixedly connected to the fixing plate 15 , and an output shaft of the motor 20 is fixedly connected to one end of the two rotating shafts 16 .

[0038] The bottom of the mounting frame 1 is provided with a plurality of hollows for heat dissipation of the photovoltaic panel 4 .

[0039] A dust sensor 14 is fixedly connected to the cleaning mechanism 3 for detecting the dust coverage rate on the surface of the photovoltaic panel 4. When natural wind cannot drive the cleaning mechanism 3, if the dust sensor 14 detects that the dust coverage rate on the surface of the photovoltaic panel 4 is high, the cleaning mechanism 3 can be driven by the motor 20 to clean the dust.

[0040] The motor 20, the dust sensor 14 and all other electronic components can be connected to the wireless control terminal. This technology is an existing mature technology, and the specific configuration and principle will not be repeated.

[0041] The adjustment frame assembly 2 includes a base 6, a support column 7 is vertically fixedly connected to the base 6, a mounting plate 8 is fixedly installed on the upper end of the support column 7 by bolts 9, an electric push rod 12 and a support arm 13 are vertically fixedly connected to the mounting plate 8, the movable end of the electric push rod 12 is hinged to the bottom of the mounting frame 1, and the upper end of the support arm 13 is hinged to the bottom of the mounting frame 1.

When the wind force in the environment increases, the dust coverage on the surface of the photovoltaic panel 4 will increase. At the same time, the wind force will also drive the cleaning mechanism 3 to clean the dust on the surface of the photovoltaic panel 4.

[0049] Natural wind can drive the wind wheel 5, and the wind wheel 5 rotates the rotating shaft 16.
