Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, specifically relating to a wind-guided, sun-tracking photovoltaic cell array and its intelligent control method. Background Technology

[0002] Photovoltaics is short for solar photovoltaic power generation system. It is a power generation system that uses the photovoltaic effect of solar cells to convert solar energy into electrical energy. In order to improve efficiency, it is usually composed of multiple solar cells to form a solar panel, and then multiple solar panels are arranged in an array to form a photovoltaic array. Each solar panel is equipped with a support rod at the bottom, and a counterweight is attached to the lower end of the support rod. Since the support rod is mostly supported in the middle of the solar panel, this type of photovoltaic unit has weak wind resistance. In strong convective weather such as typhoons and hurricanes, the solar cells are easily damaged or lost.

[0003] Meanwhile, most of these photovoltaic arrays fix the solar panels to the top of the support rod, making it difficult to adjust the angle of the solar panels according to the sun's position. There are also a few photovoltaic arrays that can adjust the angle of the solar panels to achieve sun chasing, but these photovoltaic arrays require a complex angle adjustment mechanism at the junction of the support rod and the solar panel, which is costly, complicated to control, and has poor stability in long-term use. Summary of the Invention

[0004] The purpose of this invention is to overcome one or more shortcomings in the prior art and provide a wind-guided, sun-following photovoltaic cell array and its intelligent control method.

[0005] To achieve the above objectives, the product in the technical solution adopted by the present invention is a wind-guided and sun-following photovoltaic cell array, comprising multiple photovoltaic units arranged in an array, wherein the photovoltaic unit includes a solar panel, a counterweight, and a support rod; The counterweights are located on both sides of the bottom of the solar panel. The side of the counterweights facing away from the solar panel extends outward and downward to form a wind-guiding slope. A reflective coating is provided on the wind-guiding slope. The reflective coating is used to reflect sunlight to the bottom surface of the solar panel in the adjacent photovoltaic unit to realize secondary power generation. The support rod is inserted into the counterweights in a height-adjustable manner. The top of the support rod is connected to a rotatable bracket. The side of the solar panel is connected to the bracket.

[0006] Preferably, an air guide plate is attached to the inclined surface of the air guide plate, the lower end of the air guide plate is hinged to the counterweight, and the upper end of the air guide plate is connected to the counterweight through an angle adjustment mechanism, so that the tilt angle of the air guide plate is adjustable, and the reflective coating is applied to the air guide plate.

[0007] Preferably, there are multiple solar panels arranged in a row along their length or width. The solar panels at both ends of the row have counterweights on their bottom sides, and the remaining solar panels have counterweight boxes on their bottom sides.

[0008] More preferably, the side of the counterweight box on the back side extends outward and downward at an angle to form a box air guide surface parallel to the air guide slope, and the box air guide surface is also coated with the reflective coating.

[0009] More preferably, the opposite side of the counterweight box is a vertical surface, and a spray pipe is inserted into this vertical surface. The spray pipe is inclined, with its lower end extending into the bottom of the inner cavity of the counterweight box and its upper end aligned with the back of the solar panel for spraying cooling.

[0010] More preferably, the upper surface of the counterweight box is provided with a water collection tank, the bottom wall of the water collection tank is provided with a water inlet, a drainage valve is provided at the water inlet, and the upper surface of the counterweight box is also provided with an air inlet.

[0011] More preferably, the counterweight box and the counterweight block, as well as adjacent counterweight boxes, are connected by a mortise and tenon structure.

[0012] More preferably, the top of the support rod is connected to a directionally variable connecting seat, and the bracket is rotatably connected to the connecting seat.

[0013] To achieve the above objectives, the technical solution adopted by this invention is an intelligent control method for controlling the aforementioned wind-guiding and solar-chasing photovoltaic cell array. This intelligent control method includes the following steps: S1. Collect local sensor data and local real-time online meteorological data. The local sensor data includes temperature data, humidity data, wind speed data, illumination angle data, and date and time data. The local real-time online meteorological data includes temperature data, humidity data, wind speed data, illumination angle data, date and time data, and meteorological warning data. S2. Import the data collected in step S1 into the intelligent model and analyze it through cross-validation; S3. Based on the analysis results of step S2, control the lowering and raising of the support rod, and / or the angle of the air guide plate, and / or the direction of the connecting seat, and / or whether the air inlet is inlet.

[0014] Preferably, the local sensing data in step S1 also includes the position information data of the counterweight, and step S3 issues an offset alarm based on the analysis result of step S2.

[0015] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: The wind-guiding and sun-chasing photovoltaic cell array provided by this invention places counterweights on both sides of the bottom of the solar panel, with the side of the counterweights facing away from the counterweights extending outward and downward to form a wind-guiding slope. A support rod is inserted into the upper surface of the counterweights in a height-adjustable manner, and a bracket is connected to the top of the support rod. The side of the solar panel is then connected to the bracket. By lowering the support rod, the two ends of the solar panel can be brought closer to the upper surface of the counterweights, thereby guiding the airflow upward to the solar panel using the wind-guiding slope, thus achieving wind guidance. At the same time, by raising the support rod, the solar panel can be tilted to achieve sun chasing. The structure is simple, low-cost, and has good long-term stability.

[0016] The intelligent control method provided by this invention uses an intelligent model to cross-validate and analyze local sensor data and local real-time networked meteorological data, and then controls the support rod to lower and raise based on the analysis results. It can realize multiple modes such as wind avoidance, sun chasing, nighttime folding, and rain cleaning. It has a high degree of automation and good control accuracy, and is particularly suitable for the intelligent control of the above-mentioned wind-guiding and sun-chasing photovoltaic cell array.

[0030] Example 1, as Figures 1 to 4 As shown, the wind-guiding and sun-tracking photovoltaic cell array provided by the present invention includes multiple photovoltaic units 1 arranged in an array. Each photovoltaic unit 1 includes a solar panel 10, a counterweight 20, and a support rod 30. The counterweight 20 is located on the left and right sides of the bottom of the solar panel 10. The side of the counterweight 20 facing away from the counterweight extends outward and downward at an angle, forming a wind-guiding slope 21. The support rod 30 is vertically and flexibly inserted into the upper surface of the counterweight 20. A rotatable bracket 31 is connected to the top of the support rod 30. The bracket 31 rotates... The moving axis extends in the front-to-back direction. The side of the solar panel 10 is connected to the bracket 31. Specifically, the counterweight 20 is a commercial concrete counterweight with a downward-extending hole on its upper surface. A lifting cylinder is provided in the hole. The lifting cylinder is a pneumatic cylinder or a hydraulic cylinder. The piston rod of the lifting cylinder forms a support rod 30. For easy connection, a connecting seat 32 is provided at the top of the support rod 30. The bracket 31 is rotatably connected to the connecting seat 32. In another embodiment, the connecting seat 32 is directionally connected to the top of the support rod 30.

[0031] This wind-guided, sun-chasing photovoltaic array can both lower the support rod 30 to bring the two ends of the solar panel 10 closer to the upper surface of the counterweight block 20, thereby using the wind-guided inclined surface 21 to guide the airflow above the solar panel 10, achieving wind guidance and shelter; and raise the support rod 30 to create a height difference, causing the solar panel 10 to tilt to achieve sun-chasing. It has a simple structure, low cost, and good long-term stability.

[0032] In this embodiment, a reflective coating 22 is provided on the wind guide slope 21. The reflective coating 22 is used to reflect sunlight to the bottom surface of the solar panel 10 in the adjacent photovoltaic unit 1 to improve power generation efficiency. Specifically, when the support rod 30 is raised to tilt the solar panel 10, the reflective coating 22 reflects sunlight to the bottom surface of the solar panel 10 in the adjacent photovoltaic unit 1, realizing back-side power generation. Due to the influence of angle, usually only the reflective coating 22 on one side of the wind guide slope 21 works. However, when the sun is shining directly, the solar panel 10 can be raised by raising the support rods 30 on both sides at the same height. At this time, the reflective coating 22 on both sides of the wind guide slope 21 can play a role.

[0033] In this embodiment, a single photovoltaic unit 1 has four solar panels 10, which are arranged in a row along the width direction (front-to-back direction). The bottom left and right sides of the solar panels 10 at both ends of the row are provided with counterweight blocks 20, and the bottom sides of the remaining solar panels 10 are provided with counterweight boxes 40. The upper surface of the counterweight box 40 is on the same plane as the upper surface of the counterweight block 20, and the lower surface of the counterweight box 40 is on the same plane as the lower surface of the counterweight block 20. Two counterweight boxes are located on the left and right sides of the same solar panel 20. The sides of the two counterweight boxes 40 facing each other are vertical. The sides of the two counterweight boxes 40 located on the left and right sides of the same solar panel 20 extend outward and downward to form a box air guide surface 41 on the same plane as the air guide slope 21. The box air guide surface 41 is also coated with a reflective coating. In order to improve the counterweight effect, the counterweight box 40 and the counterweight block 20, and the adjacent counterweight boxes 40 are connected by a tenon and mortise structure 42, so that all the counterweight blocks 20 and counterweight boxes 40 located on the same side of the solar panel 10 in a single photovoltaic unit 1 are connected as one.

[0034] In this embodiment, a water-collecting trough 43 is provided on the upper surface of the counterweight box 40. The cross-section of the water-collecting trough 43 is an inverted trapezoid with a larger top and a smaller bottom. When the support rod 30 is lowered so that the two ends of the solar panel 10 are close to the upper surface of the counterweight block 20 and the counterweight box 40, the top opening of the water-collecting trough 43 is not blocked. The bottom wall of the water-collecting trough 43 is provided with a water inlet. A drainage valve 44 is provided at the water inlet. The water inlet extends downward into a cylindrical shape with openings at both ends. The drainage valve 44 includes a movable baffle 441 that abuts against the lower end of the cylinder and a spring 442 that connects the middle of the movable baffle 441 to the upper part of the cylinder wall. The spring 442 has the tendency to tighten the movable baffle 441 to block the water inlet. In rainy weather, it can be drained. Rainwater is collected by the water collection trough 43. When the rainwater pressure in the water collection trough 43 is greater than the tension of the spring 442, the movable baffle 441 opens, and the rainwater enters the counterweight box 40 to achieve rainwater collection. Furthermore, the upper surface of the counterweight box 40 is also provided with an air inlet 45. Spray pipes 46 are inserted into the vertical surfaces of the two counterweight boxes 40 on the left and right sides of the same solar panel 20 facing each other. The spray pipes 46 are set at an angle, with their lower end extending into the bottom of the inner cavity of the counterweight box 40 and their higher end facing the back of the solar panel 10. Air can be introduced through the air inlet 45 to force the water in the counterweight box 40 out along the spray pipe 46, thereby cooling the back of the solar panel 10 and improving power generation efficiency.

[0035] In this embodiment, an infrared distance sensing module (not shown in the figure) is also provided below the solar panel 10 to detect the vibration frequency of the solar panel 10. When the wind speed is too high and the swaying of the solar panel 10 exceeds the set range, all support rods 30 are lowered to avoid the wind.

[0036] The wind-guided solar photovoltaic cell array provided by this invention can reduce the overall weight by about 50% through a wind-guided strategy. It can also add water to the counterweight box to increase the counterweight according to the actual situation, preventing the overall displacement of the components due to insufficient counterweight under strong convective weather. It is particularly suitable for sites with load requirements such as rooftops.

[0037] It should be noted that in the above embodiments, the spacing between the photovoltaic units 1, as well as the tilt angle of the wind guide slope 21 and the air guide surface 41 of the box, are based on maximizing the density of the photovoltaic units 1 and the power generation on the back of the solar panel 10.

[0038] Example 2, as Figure 5 As shown, Embodiment 2 is basically the same as Embodiment 1, except that in Embodiment 2, a guide plate 23 is attached to the guide slope 221, and a reflective coating is applied to the upper surface of the guide plate 23. The lower end of the guide plate 23 is hinged to the counterweight 20, and the upper end of the guide plate 23 is connected to the counterweight 20 through the angle adjustment mechanism 24, so that the tilt angle of the guide plate 23 is adjustable. This allows for flexible adjustment of the reflective angle of the reflective coating, further improving power generation efficiency. The adjustment amount of the tilt angle of the guide plate 23 is calculated by combining the illumination angle data with the reflection angle of the reflective coating and the angle of the guide slope 221. The angle adjustment mechanism 40 is hinged to the guide plate 23, and the angle adjustment mechanism 40 includes a cylinder or a hydraulic cylinder.

[0039] Similarly, a rotatable air guide plate 23 can also be installed on the air guide surface 41 of the counterweight box 40, and the reflective coating on the air guide surface 41 of the box can be applied to the air guide plate 23 to improve power generation efficiency.

[0040] In this embodiment, the tilt angle of the wind guide plate 23 needs to consider not only the illumination angle but also the current wind speed. The priority of these two factors is determined according to the actual situation. Specifically, when the wind speed is less than 10.8 m / s, the wind load on the support rod 30 is relatively small, and the tilt angle of the wind guide plate 23 only considers chasing the sun and matching the current illumination angle as much as possible to maximize the power generation efficiency. When the wind speed is greater than 10.8 m / s but less than 20.7 m / s, the tilt angle of the wind guide plate 23 is mainly for chasing the sun and allows for a slight adjustment of ±5° on the basis of maximizing the power generation efficiency, so as to release some wind pressure, reduce the wind load on the support rod 30, and achieve a "flexible transition". When the wind speed is greater than 20.7 m / s, the tilt angle of the wind guide plate 23 only considers guiding and avoiding the wind, and directly rotates to fit with the wind guide slope 221. At the same time, all support rods 30 are lowered so that the two ends of the solar panel 10 are close to the upper surface of the counterweight block 20 and the counterweight box 40.

[0041] This invention also provides an intelligent control method for controlling the aforementioned wind-guided, sun-following photovoltaic cell array, such as... Figure 6As shown, the intelligent control method includes the following steps: S1. Collect local sensor data and local real-time online meteorological data. Local sensor data includes temperature data, humidity data, wind speed data, illumination angle data, date and time data. Local real-time online meteorological data includes temperature data, humidity data, wind speed data, illumination angle data, date and time data, and meteorological warning data. S2. Import the data collected in step S1 into the intelligent model and analyze it through cross-validation; S3. Based on the analysis results of step S2, control the lowering and raising of the support rod, the angle of the air guide plate, the direction of the connecting seat, and whether air enters through the air inlet, thereby achieving multiple modes such as wind avoidance, sun chasing, cleaning, cooling, and nighttime retraction. Specifically: In wind avoidance mode, when the wind speed data collected in step S1 exceeds the set value, or the gale warning data in the weather warning data exceeds the set value, all support rods are controlled to be lowered to ensure that both ends of all solar panels are attached to the upper surface of the counterweight block and counterweight box. The wind guide slope and the box's wind guide surface are used to guide the wind and reduce the damage of strong winds to the solar panels. In the solar chasing mode, when the illumination angle in the data collected in step S1 exceeds the set value, the support rod on one side is raised or the support rods on both sides are raised at different heights to form a height difference, so that the solar panel tilts to obtain the maximum power generation efficiency and achieve solar chasing. In the cleaning mode, when the humidity data collected in step S1 exceeds the set value and the rainfall warning data in the weather warning data does not exceed the set value, the support rods on both sides are controlled to descend and rise alternately and the direction of the connecting seat is constantly changed, so that the solar panel swings left and right, thereby using rainwater to self-clean the solar panel, and the water flow is controlled at intervals to guide the flushing and ash removal. In the cooling mode, when the temperature data collected in step S1 exceeds the set value, the support rods on one or both sides are controlled to descend, and air is then introduced through the air inlet to press out the water in the counterweight box to cool the back of the solar panel, reducing the problem of low power generation efficiency of the module caused by high temperature weather. This cooling can also form a cleaning effect to a certain extent. In the nighttime retraction mode, when the light data collected in step S1 is lower than the set value, the support rods on both sides are lowered to retract the solar panels at night.

[0042] The intelligent control method provided by this invention uses an intelligent model to cross-validate and analyze local sensor data and local real-time networked meteorological data, and then controls the support rod to lower and raise based on the analysis results. It can realize multiple modes such as wind avoidance, sun chasing, rain cleaning, cooling, and nighttime retraction. It has a high degree of automation and good control accuracy, and is particularly suitable for the intelligent control of the above-mentioned wind-guiding and sun-chasing photovoltaic cell array.

[0043] Furthermore, the local sensing data in step S1 also includes the position information data of the counterweight, and step S3 issues an offset alarm based on the analysis results of step S2.

[0044] The intelligent control method provided by this invention can autonomously determine the weather of the local power station on that day, and collect meteorological data from the Internet as well as sensor information such as actual temperature, solar position, wind speed, and humidity on site. It can intelligently adjust the height and angle of photovoltaic modules, and make autonomous decisions on whether to lower all support rods to avoid wind based on background early warning information. It can also analyze the solar angle of different seasons through historical logs, thereby adjusting the tilt angle and lifting height of the solar panels to adapt and obtain the maximum power generation efficiency.

[0045] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be covered within the scope of protection of the invention.
