Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a pressure-bearing positioning structure of a photovoltaic bracket. Background Art

[0002] Photovoltaic brackets are an important part of photovoltaic power generation systems. They are mainly used to support and fix photovoltaic modules to ensure that they can be stably installed under various environmental conditions. The design and material selection of photovoltaic brackets directly affect the overall performance and durability of the photovoltaic system. Brackets are usually made of corrosion-resistant metal materials such as aluminum alloy or hot-dip galvanized steel, and have the ability to resist climatic conditions such as wind and snow to ensure the safety of the system in severe weather.

[0003] The photovoltaic bracket in the prior art generally sets a cement block on the surface as a base first. When the setting is completed, the photovoltaic bracket is connected to the cement base by bolts or welding. The triangular photovoltaic bracket provides stable support for the solar panel. However, since the photovoltaic bracket in the prior art can only adjust the angle of the solar panel through a simple structure and driving equipment, the adjustable angle of the solar panel is limited and cannot be flexibly adjusted according to changes in lighting conditions, resulting in the inability to fully utilize solar energy resources during certain periods of time, thereby affecting the power generation. Summary of the invention

[0004] The purpose of the present invention is that when the adjusting rod moves, it will push or pull the placement plate to offset through the universal coupling. At this time, the offset placement plate will rotate and offset with the ball groove and the ball axis as the center point. When the angle of the placement plate changes, the ball axis and the ball groove will rotate flexibly so that the placement plate drives the solar panel to change its angle, thereby compensating for the defect that the photovoltaic bracket positioning structure in the prior art cannot be flexibly adjusted according to changes in lighting conditions, which may result in the inability to fully utilize solar energy resources in certain time periods, thereby affecting the power generation.

Select any three adjacent points and obtain the average of the absolute values ​​of their adjacent differences. Compare the average with the preset value. When the average is greater than the preset value, replace the middle value with the preset value to generate a new grayscale image.

An adjusting plate 24 is correspondingly distributed on the bottom surface of each adjusting rod 23. When the adjusting rod 23 moves, it will push or pull the placement plate 19 to offset through the universal coupling 22. At this time, the offset placement plate 19 will rotate and offset with the ball groove 20 and the ball shaft 18 as the center point. When the angle of the placement plate 19 changes, it will movably rotate between the ball shaft 18 and the ball groove 20, so that the placement plate 19 drives the solar panel 21 to change its angle.

[0053] Two bearings 25 are correspondingly distributed on one side and the other side surface of each adjustment plate 24. The outer surface of the bearing 25 is fixedly connected to the inner wall of the adjustment plate 24. A clamping shaft 26 is correspondingly distributed on the inner wall of every two bearings 25. The inner walls of the bearings 25 are movably and rotatably connected to the outer surfaces of the clamping shafts 26. The three clamping shafts 26 are respectively fixedly connected to the outer surfaces of the first ball slider 9, the second ball slider 12, and the limit ring 14. The inner wall of the adjustment plate 24 is in movable contact with the outer surface of the bracket 1, and the outer surface of the clamping shaft 26 is in movably contact with the inner wall of the sliding groove 3.

[0054] The working process of the present invention is as follows: when it is necessary to use the photovoltaic bracket pressure positioning structure, the base 6 is first installed on the ground, and the three bases 6 are arranged in a triangle. When the arrangement is completed, the bracket 1 is placed between the three bases 6, and the positioning plate 5 installed on the surface of one side of the bracket 1 is fixedly connected to the base 6 by bolts. When the installation is completed, the support rod 15 is inserted into the inner wall of the positioning hole 2. When the support rod 15 is inserted, the card plate 16 installed on its outer surface will contact the top surface of the bracket 1, and the support rod 15 is moved so that the card plate 16 will The bracket 1 is wrapped, and when the support rod 15 is inserted, the fixing bolt 17 is inserted into the inner wall of the clamping plate 16. The fixing bolt 17 is rotated so that the fixing bolt 17 is rotated and inserted into the hole opened on the surface of one side of the bracket 1, so that the clamping plate 16 and the bracket 1 are fixedly connected to improve the structural strength. When the bracket 1 is installed, the top end of the universal coupling 22 is connected to the bottom end of the placement plate 19, and the ball shaft 18 installed on the top surface of the support rod 15 is connected to the ball groove 20, thereby realizing the installation of the photovoltaic bracket and the positioning structure.

[0055] When the angle of the solar panel 21 needs to be adjusted, the angle direction of the solar panel 21 can be changed by starting the first motor 7 or the second motor 10. When the first motor 7 or the second motor 10 is started, the first screw rod 8 or the second screw rod 11 installed at its output end is driven to rotate. When the first screw rod 8 or the second screw rod 11 rotates, it rotates on the inner wall of the rotating groove 4, and the first ball slider 9 and the second ball slider 12 are installed on the outer surfaces of the first screw rod 8 and the second screw rod 11 respectively. Therefore, when the first screw rod 8 or the second screw rod 11 rotates, the first ball slider 9 or the second ball slider 12 installed on its outer surface The two ball sliders 12 move along their surfaces, and the outer surfaces of the first ball slider 9 and the second ball slider 12 are correspondingly provided with clamping shafts 26. At this time, the moving first ball slider 9 and the second ball slider 12 will respectively drive the clamping shafts 26 installed on their outer surfaces to move, and the clamping shafts 26 extend out through the sliding groove 3 and are movably and rotatably connected with the bearings 25 installed on the inner wall of the adjusting plate 24. Therefore, when the clamping shaft 26 moves, the adjusting plate 24 and the adjusting rod 23 are driven to move through the bearings 25, and when the adjusting rod 23 moves, the placement plate 19 is pushed or pulled to deviate through the universal coupling 22. At this time, the deviation The displaced placement plate 19 will rotate and offset with the ball groove 20 and the ball shaft 18 as the center point. When the angle of the placement plate 19 changes, the ball shaft 18 and the ball groove 20 will rotate flexibly, so that the placement plate 19 drives the solar panel 21 to change its angle. When the angle of the placement plate 19 changes, the universal coupling 22 will rotate due to the deflection of the placement plate 19 to meet the angle change of the placement plate 19, and the first motor 7 and the second motor 10 are started to change the angle between the adjustment rod 23 and the placement plate 19, so that the adjustment rod 23 adjusts the height of the placement plate 19 through the universal coupling 22 to change. The solar panel 21 can be adjusted at multiple angles, and a limit rod 13 is installed on the inner wall of the rotating groove 4, and a limit ring 14 is installed on the outer surface of the limit rod 13. When the two adjustment rods 23 drive the placement plate 19 to adjust the angle, the angle of the placement plate 19 changes, thereby driving the other adjustment rod 23 to move. At this time, the other adjustment rod 23 will drive the limit ring 14 to adaptively move on the outer surface of the limit rod 13 through the clamping shaft 26, thereby cooperating with the movement of the other two adjustment rods 23, so that when the adjustment is completed, the three adjustment rods 23 will form a triangle with the bracket 1, thereby improving the stability and strength of the photovoltaic equipment.

[0056] Example 2

[0057] like Fig.10 As shown, the photovoltaic support pressure positioning structure includes a support 1 and a light control system, and the light control system includes a power generation detection unit, a power generation efficiency analysis unit and an execution unit;

[0058] The power generation detection unit is used to obtain the real-time current data In of the DC power outputted from the output end of the solar panel 21 through the current sensor and send it to the power generation efficiency analysis unit;

[0059] The power generation efficiency analysis unit obtains and processes the real-time current data, presets a detection period and a current fluctuation threshold, calculates the current fluctuation coefficient according to the real-time current data within the detection period T, and determines the current fluctuation coefficient by the current fluctuation threshold to generate an abnormal signal, and sends the abnormal signal to the execution unit;

[0060] The specific process of generating an abnormal signal is as follows:

[0061] S1. Obtain real-time current data In and calculate the current fluctuation coefficient W according to the following formula:

[0062]

[0063] , where i=1, 2, 3, ..., n, the current fluctuation coefficient is used to reflect the fluctuation of the production efficiency of the solar panel 21. The larger the current fluctuation coefficient, the larger the fluctuation amplitude of the solar panel 21. On the contrary, the larger the current fluctuation coefficient, the more stable the fluctuation amplitude of the solar panel 21 tends to be.

[0064] S2. Obtain a preset current fluctuation threshold value. If the current fluctuation coefficient is greater than or equal to the current fluctuation threshold value, an abnormal signal is generated and sent to the execution unit;

[0065] If the current fluctuation coefficient is less than the current fluctuation threshold, no signal is generated;

[0066] The execution unit is used to control the start of the first motor 7 or the second motor 10 after obtaining the abnormal signal to change the position of the first ball slider 9 or the second ball slider 12 on the surface of the first screw rod 8 or the second screw rod 11, thereby pushing the adjusting rod 23 to change the angle orientation of the placement plate 19 by moving the first ball slider 9 or the second ball slider 12, so that the sunlight reaches the maximum value at that time.

[0067] Example 3

[0068] like Fig.10 As shown, the light control system also includes a meteorological collection unit, which is used to collect meteorological information and send it to the correction processing unit. The correction processing unit obtains the meteorological information and analyzes and normalizes it to generate a meteorological value Q.

[0069] The meteorological information includes meteorological pictures collected by image sensors.

[0070] The steps for analysis normalization are as follows:

[0071] Select the last framed image of a certain area of ​​the meteorological picture, convert the framed image into a red image, a green image, and a blue image, and then convert them into grayscale images respectively, select any three adjacent points and obtain the average value of the absolute value of their adjacent differences, compare the average value with the preset value, and when the average value is greater than the preset value, replace the intermediate value with the preset value to generate a new grayscale image, obtain the average value of the new grayscale image, and mark it as R, T and Y respectively, according to the formula: meteorological value Q=e1*R+e2*T+e3*Y; the smaller the current fluctuation coefficient W is, the more it needs to be changed, and the larger T and Y are, the worse the lighting is, the stronger the interference is, that is, the larger the meteorological value is, the worse the lighting is, the stronger the interference is, where e1, e2, and e3 are the corresponding weight coefficients of the average value of the new grayscale image, and the weight coefficient makes the result of the simulation calculation closer to the true value;

[0072] Then obtain the current fluctuation coefficient W of the power generation efficiency analysis unit and combine it with the meteorological value Q to generate the interference value:

[0073]

[0074] , when the K value is larger, the interference of meteorological environment on lighting is smaller, and vice versa, the interference is stronger;

[0075] The interference value K is compared with the preset interference value k0. When K < k0, no interference signal is generated. Otherwise, an interference signal is generated and sent to the execution unit. k1 and k2 are normalization coefficients of the current fluctuation coefficient W and the meteorological value Q, respectively. The normalization coefficients ensure that the units are unified or cleared.

[0076] When the execution unit receives an abnormal signal and an interference signal at the same time within a preset time, the interference signal is taken as the first priority level to indirectly control the operation of the first motor 7 and the second motor 10; thereby reducing the impact of the meteorological environment on the automatic control and matching of illumination, and ensuring the precise operation of the present invention.

[0077] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0078] The execution unit indirectly controls b through the a drive unit, so that the photovoltaic panel changes its orientation angle to ensure constant sunlight. It should be noted that this determination is a curve. The solar intensity in the morning, noon and evening is different, and the amount of electricity generated is also different.

[0079] The above formulas are all dimensionless and numerical calculations. The formula is a formula obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
