Description

Technical Field

[0001] The invention belongs to the field of photovoltaic power generation, and in particular relates to a solar photovoltaic component mounting bracket system. Background Art

[0002] Photovoltaic power generation is the process of directly converting light energy into electrical energy. Photovoltaic panels are used to convert solar energy into electricity. This technology can be used to generate clean energy. The continuous development of photovoltaic power generation technology has made it play an increasingly important role in the energy industry. In addition to its popular application in rooftops and large-scale photovoltaic power stations, more efficient solar cells and integrated systems are also being researched and developed to improve energy efficiency and reduce costs.

[0003] Existing photovoltaic power generation brackets generally include several main types: fixed brackets, single-axis solar tracking brackets and dual-axis solar tracking brackets. The dual-axis solar tracking brackets can not only adjust the tilt angle, but also adjust according to the altitude and azimuth of the sun to further improve energy output. However, existing dual-axis solar tracking brackets usually use parallel installation of solar panels, which makes the installation process difficult and the maintenance time-consuming and labor-intensive. At the same time, they have no self-cleaning function and require special equipment for cleaning. At the same time, they are easily covered with rain and snow in winter, increasing operation and maintenance costs. Summary of the invention

An inspection port 22 is provided at the bottom of the hollow steel column 21, and an inspection end cover 23 is installed on the inspection port 22. A water diversion pipe 24 and a wire threading pipe 25 are provided in the hollow steel column 21. The water diversion pipe 24 is connected to the water supply pipe 13, and the wire threading pipe 25 is connected to the pre-buried wire pipe 12. Optical cables and electrical cables are provided in the wire threading pipe 25 and the pre-buried wire pipe 12. The top of the wire threading pipe 25 passes through the hollow steel column 21. A fixing component 5 is provided at the top of the hollow steel column 21, and the hollow steel column 21 and the fixing component 5 are connected by a light-chasing structure 3.

[0049] The light-chasing structure 3 includes a tube seat 31, which is threadedly connected to the hollow steel column 21. An inner sleeve 32 is rotatably connected to the tube seat 31, a rotating gear 33 is connected to the bottom end of the inner sleeve 32, a rotating platform 34 is connected to the top end of the inner sleeve 32, an outer sleeve 35 is splined to the inner sleeve 32, a swing gear 36 is connected to the bottom end of the outer sleeve 35, and a horizontal bevel gear 37 is connected to the top end of the outer sleeve 35. The hollow steel column 21 is flange-connected with a driving motor on the left and right sides respectively, a worm 38 is connected to the output shaft of the driving motor, and the worm 38 is respectively meshed with the rotating gear 33 and the swing gear 36. A soft water pipe 39 is arranged in the tube seat 31, and the soft water pipe 39 is connected to the water diversion pipe 24. A swing mechanism 4 is arranged on the rotating platform 34.

[0050] The swing mechanism 4 includes a rotating shaft 41, which is rotatably connected to the rotating table 34. A vertical bevel gear 42 and a swing hollow rod 43 are installed on the rotating shaft 41. The horizontal bevel gear 37 and the vertical bevel gear 42 are meshed with each other. One end of the swing hollow rod 43 is connected to a fixing component 5. A limiting pin 44 is fixed on the swing hollow rod 43. The limiting pin 44 is slidably connected in a limiting track 45. The limiting track 45 is fixed on the rotating table 34. A waterproof cover 46 is fixed on the limiting track 45. The swing hollow rod 43 is fixed with an arc baffle 47 above the waterproof cover 46, and a soft water pipe 39 is arranged in the swing hollow rod 43.

[0051] The working principle and beneficial effects of the above technical solution are as follows: the hollow steel column 21 in the trunk component 2 supports the solar panel 53, and the water pipe 24 and the threading pipe 25 are hidden in the space in the hollow steel column 21, which plays a role of protection and beauty. The inspection port 22 can facilitate the operator to connect the cable, which plays a maintenance role. The chasing light structure 3 at the top of the hollow steel column 21 can chase the sun;

[0052] When chasing light, the electric drive drives the worm 38 to rotate. First, the worm 38 drives the swing gear 36 to rotate. When the swing gear 36 rotates, the outer sleeve 35 and the horizontal bevel gear 37 rotate synchronously. The horizontal bevel gear 37 and the vertical bevel gear 42 mesh with each other to drive the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, the swinging hollow rod 43 on the rotating shaft 41 swings in the vertical plane. When the swinging hollow rod 43 rotates, the limiting track 45 and the limiting pin 44 protect it. When the swinging hollow rod 43 swings , the solar panel 53 thereon is consistent with it, and stops after the optimal pitch angle is finally determined, and then the worm 38 drives the rotating gear 33 to rotate, and the rotating gear 33 drives the inner sleeve 32 and the rotating platform 34 to rotate, and the rotation of the rotating platform 34 synchronously causes the swinging hollow rod 43 to rotate in the horizontal plane, so as to realize the horizontal plane rotation of the solar panel 53, and the swinging hollow rod 43 swings so that the soft water pipe 39 inside it shrinks back and forth, and the waterproof cover 46 shields the light chasing structure 3 to prevent water from entering the light chasing structure 3;

[0053] The present invention uses a hollow steel column 21 to support the solar panel 53. This design can ensure the stability of the solar panel 53 while occupying a small space. At the same time, the internal hollow structure can hide the water pipe 24 and the threading pipe 25 to avoid the water pipe 24 and the threading pipe 25 from being broken due to long-term light and weathering, and has good aesthetics.

[0054] The light-chasing structure utilizes the design of the inner sleeve 32 and the outer sleeve 35 to realize rotation in different directions. This design can ensure the integrity and coupling of the rotation of the solar panel 53, and utilizes the transmission structure of the worm 38, the gear and the bevel gear, which has the advantages of high transmission accuracy, strong load and long service life. At the same time, the design of the upper limit pin 44 and the limit track 45 on the swinging hollow rod 43 can ensure the stability of the swinging hollow rod 43 during the rotation process and avoid deflection of the rotation. The design of the waterproof cover 46 on the swinging hollow rod 43 can prevent water from entering the light-chasing structure 3 and ensure the dryness of the hollow steel column 21.

[0055] Example 3

[0056] On the basis of Example 1, the fixing component 5 includes a four-sided ring platform 51, which is installed on the swinging hollow rod 43. The outer side of the four-sided ring platform 51 has a plurality of spokes 52 on the annular hinge, and a plurality of solar panels 53 are connected between the spokes 52 by bolts. A folding rod 1 54 is hingedly connected below the spokes 52, and a folding rod 2 55 is hingedly connected at the other end of the folding rod 1 54, and the folding rod 2 55 is hingedly connected to the swinging hollow rod 43. A plurality of hydraulic struts 56 are arranged below the four-sided ring platform 51, and the plurality of hydraulic struts 56 are annularly hingedly connected to the swinging hollow rod 43, and the working ends of the hydraulic struts 56 are hingedly connected to the folding rod 1 54 and the folding rod 2 55.

[0057] The beneficial effects of the above technical solution are as follows: the solar panel 53 is fixed on the spoke 52, and when the hydraulic support 56 contracts, it drives the folding rod 1 54 and the folding rod 2 55 to contract and fold inward, and the folding rod 1 54 then drives the spoke 52 to rotate, and the spoke 52 rotates from horizontal to vertical. When it is necessary to unfold, the hydraulic support 56 extends, drives the folding rod 1 54 and the folding rod 2 55 to expand, and the folding rod 1 54 then drives the spoke 52 to rotate, and the spoke 52 rotates from vertical to horizontal. The folding rod 1 54 and the folding rod 2 55 support the spoke 52 under the action of the hydraulic support 56;

[0058] The present invention utilizes folding rod 1 54 and folding rod 2 55 to unfold and retract the solar panel 53. This design can fold the solar panel 53 when photovoltaic power generation cannot be performed, thereby reducing the effective area of ​​the entire bracket, reducing the impact of wind on the bracket, and avoiding snow or dust accumulation on the solar panel 53. The folding design can reduce the difficulty of workers in installing or repairing the solar panel 53, thereby improving installation efficiency. At the same time, the design of folding rod 1 54, folding rod 2 55 and hydraulic support 56 can reduce the structural size, thereby reducing the space occupied by the bracket, and can improve the efficiency of space utilization.

[0059] Example 4

[0060] On the basis of Example 1, the snow clearing assembly 6 includes a sliding cross plate 61, which is slidably connected in a slide groove 62, which is installed on the spoke 52, and a scraper bar 63 is installed on the sliding cross plate 61. The scraper bar 63 and the solar panel 53 are slidably connected. The sliding cross plate 61 is provided with a heating strip 64 on the front side of the scraper bar 63, and a driving device 65 is installed on the sliding cross plate 61.

[0061] The beneficial effects of the above technical solution are as follows: when snow and ice accumulate on the solar panel 53, the sliding horizontal plate 61 slides along the slide groove 62 under the action of the driving device 65. During the sliding process of the sliding horizontal plate 61, the heating strip 64 heats and melts the snow and ice on the solar panel 53, and the scraping strip 63 scrapes off the melted snow and ice and pushes them away from the solar panel 53, and then the snow removal component 6 is reset;

[0062] The present invention utilizes the heating strip 64 to melt the accumulated snow and ice. This design can reduce the adhesion of the accumulated snow and ice on the solar panel 53, and avoid the accumulated snow being unable to be scraped off the solar panel 53 due to freezing during the cleaning process, resulting in a reduction in the power generation efficiency of the solar panel 53. At the same time, the design of the scraping strip 63 can scrape off the attached ice, snow and water droplets at the same time, and avoid the residual snow and water droplets on the solar panel 53 causing secondary freezing, thereby increasing the working time and reducing the working efficiency.

[0063] Example 5

[0064] On the basis of Example 1, the spray assembly 7 includes a water tank 71, the flange of the water tank 71 is installed at the top of the extended hollow rod 79, the extended hollow rod 79 is threadedly connected to the top of the swing hollow rod 43, and a plurality of nozzles 72 are provided in an annular shape on the water tank 71. The water tank 71 is rotatably connected to an electric water retaining plate 73 above the nozzle 72, and the electric water retaining plate 73 cooperates with the nozzle 72. A soft water pipe 39 is connected below the water tank 71, and the soft water pipe 39 is provided on the extended hollow rod. In 79, a water retaining ring 74 is installed on the extended hollow rod 79, an air-compressed telescopic column 75 is installed on the top of the water tank 71, a pressure plate 76 is installed on the working end of the air-compressed telescopic column 75, the pressure plate 76 is slidably connected in the water tank 71, a one-way valve 77 is provided on the pressure plate 76, the one-way valve 77 is connected to the internal pipeline of the air-compressed telescopic column 75, a top opening 78 is provided in the water tank 71, the one-way valve 77 and the top opening 78 cooperate with each other, and the spray assembly 7 is supplied with water through the water storage structure 8.

[0065] The water storage structure 8 includes a pre-buried water tank 81, which is provided with a water outlet 82, which is connected to the water supply pipe 13. A booster pump 83 is installed in the pre-buried water tank 81, and the output end of the booster pump 83 is connected to the water outlet 82. The pre-buried water tank 81 is provided with a water injection port 84, and a filter cylinder net 85 is provided in the water injection port 84. The filter cylinder net 85 and the water injection port 84 slide relative to each other, and a dust cover 86 is threadedly connected to the water injection port 84.

[0066] The beneficial effects of the above technical solution are as follows: when the snow-clearing component 6 performs dust cleaning, the booster pump 83 in the embedded water tank 81 works, and the booster pump 83 delivers water from the water outlet 82 to the water supply pipe 13, and the water then enters the water tank 71 and flows out from the nozzle 72, and the electric water retaining plate 73 rotates to block the nozzle 72, and the water flow hits the electric water retaining plate 73 and falls on the solar panel 53 below. As the electric water retaining plate 73 rotates, the shielding effect on the nozzle 72 is small, and the water flow range of the nozzle 72 increases, gradually wetting the solar panel 53. When there is insufficient water in the embedded water tank 81, after opening the dust cover 86, the water is poured into the water tank 81 through the water injection port 84. Water is injected into the filter cartridge 85, and the filter cartridge net 85 filters the injected water. When the filter residue of the filter cartridge net 85 accumulates, it is slid out of the water injection port 84 for washing, and then put into the water injection port 84 again. When the weather is cold in winter, after the spray assembly 7 is used, the air compression telescopic rod 75 is started, driving the pressure plate 76 to slide in the water tank 71, squeezing and draining the liquid in the water tank 71. When the pressure plate 76 slides to the lowest end, the top port 78 squeezes the one-way valve 77 to open it, and the compressed air in the pipeline of the air compression telescopic rod 75 flows into the soft water pipe 39, and the liquid in the soft water pipe 39 is back-drained into the pre-buried water tank 81, and then the air compression telescopic rod 75 drives the pressure plate 76 to reset;

[0067] The present invention utilizes a pre-buried water tank 81 and a booster pump 83 for water supply. This design can ensure the independence of the water source, does not require manpower to lay a water pipe network, and only requires regular water filling. The water source is fixed, so there is no need to worry about water outages, and long-term manual supervision can be avoided. The booster pump 83 can be adjusted to achieve control of different ranges of water flow. At the same time, the design of the nozzle 72 and the electric water baffle 73 can ensure that when the nozzle 72 is fixed, the solar panel 53 is fully covered by the spray water flow, avoiding the solar panel 53 from having dead corners and being unable to spray. Since the swing hollow rod 43 and the extended hollow rod 79 are threadedly connected, they can be disassembled or installed according to actual conditions.

[0079] The control center controls the execution unit based on the data results of the data processing center, including the following steps:

[0080] Step 1: The data processing center calculates the light source coefficient of the i-th rotation of the light-chasing structure 3 based on the GPS sensor, light sensor, voltage sensor, current sensor, pressure sensor, angle sensor, rotation sensor and wind speed sensor:

[0081]

[0082] Where: C di is the light source coefficient of the i-th rotation of the light-chasing structure 3, c u is the detection value of the photosensor, m0 is the mass of the solar panel 53, in kg, and g is the gravitational acceleration, in m / s 2 , β is the detection value of the angle sensor, c u0 is the photosensitivity value during the day, F is the detection value of the pressure sensor, the unit is N, ρ is the air density value, the unit is kg / m 3 , v is the detection value of the wind speed sensor, in m / s, S is the effective area of ​​the solar panel 53, in m 2 , δ is the detection value of the GPS sensor, U i is the voltage sensor detection value at the i-th rotation, in V, I i is the current sensor detection value at the i-th rotation, in A, α i is the detection value of the rotation sensor in the i-th rotation, U i+1 The voltage sensor detection value at the i+1th rotation, in V, I i+1 is the current sensor detection value at the i+1th rotation, in A, α i+1 is the detection value of the rotation sensor in the i+1th rotation;

[0083] Step 2: Data Processing Center Comparison C di and C di+1 ;

[0084] When C di <C di+1 When C di >C di+1 When C di >C di-1 And C di >C di+1 When , the control center controls the execution unit light tracking structure 3 to stop rotating.

[0085] The beneficial effects of the above technical solution are as follows: since the sun revolves around the earth, the sun has a certain pitch angle and rotation angle relative to the earth, so the energy obtained by the solar panel 53 is different when the angle to the sun is different, and the power generation power of the solar panel 53 is also different. When the solar panel 53 is perpendicular to the incident angle of the sunlight and the solar panel rotates to face the sun following the rotation of the sun, the power generation power of the solar panel 53 is the maximum power generation power of the whole day. Using the above idea, the power generation power after and before the rotation of the solar panel 53 is compared to judge the front view angle of the sun relative to the solar panel 53, and finally obtain the light chasing angle of the solar panel 53, so as to realize the real-time light chasing of the sun.

[0086] The present invention utilizes a data processing center, a detection unit, and an execution unit to monitor the power generation of the solar panel 53 in real time, and calculates the optimal rotation angle based on the comparison, thereby ensuring that the solar panel 53 can rotate in real time following the rotation of the sun, thereby achieving the maximum power generation of solar energy and improving economic benefits and production efficiency.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
