Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic brackets, and more specifically, the utility model relates to a drainage mechanism of a photovoltaic bracket. Background Art
[0002] A photovoltaic panel is a device that directly converts solar energy into electrical energy. It consists of multiple solar cell units, which are connected in series or parallel to form a large-area photovoltaic power generation array capable of generating sufficient voltage and current. A photovoltaic bracket is an indispensable part of a photovoltaic power station and is a special bracket used for installing, placing, carrying, fixing, and adjusting photovoltaic modules.
[0003] Currently, in order to keep the photovoltaic modules clean and operate efficiently, it is usually necessary to prevent rainwater backflow and corrosion of the photovoltaic brackets through a drainage mechanism. The current drainage mechanism, such as Chinese Patent Application No.: CN202320723931.9, a drainage mechanism for a photovoltaic bracket, filters impurities through a filter screen, leaving the impurities above the filter screen, and the clean rainwater flows into the drainage groove, and then is transported through the drainage port and the lower drainage groove, thereby reducing the rainwater scouring of the bracket base.
[0004] However, although this device can filter and discharge rainwater through the design of the filter screen, after each rainfall, it is necessary to replace the filter screen to restore its filtering function. This filtering method cannot ensure normal drainage operations when the rainfall is large and there are many impurities on the photovoltaic panels. When the filter screen is blocked by stones or leaves on a large area during rainfall, the rainwater will also scour the supporting part of the bracket, resulting in a weakened fixing strength. Therefore, it is necessary to improve and optimize it. Content of the Utility Model

[0007] On the left side of the inclined beam, a water inlet tank is fixedly installed. The water inlet tank is located at the drainage position of the drainage plate. A filter plate is fixedly installed on the top of the water inlet tank. A hydraulic chamber is fixedly installed at the bottom of the water inlet tank.

And after sundries accumulate on the top of the filter plate, the elastic potential energy of the spring drives the scraper to move forward, so as to remove the sundries accumulated on the top of the filter plate. Compared with the traditional device, through the setting of the blades, when it rains outside, the scraper is pulled to the rear of the filter plate, and when the drainage volume becomes smaller, the scraper automatically removes the sundries on the top of the filter plate, effectively ensuring the normal operation of drainage.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] As Figures 1 to 7 shown, the present invention provides a drainage mechanism for a photovoltaic support, including a column 1. A diagonal beam 2 is fixedly installed at the top of the column 1. A photovoltaic module 3 is fixedly installed at the top of the diagonal beam 2. A drainage plate 4 is fixedly installed at the front end of the diagonal beam 2. The drainage plate 4 is located below the photovoltaic module 3;
[0027] A water inlet tank 5 is fixedly installed on the left side of the diagonal beam 2. The water inlet tank 5 is located at the drainage position of the drainage plate 4. A filter plate 6 is fixedly installed at the top of the water inlet tank 5. A hydraulic chamber 7 is fixedly installed at the bottom of the water inlet tank 5. The water inlet tank 5 and the hydraulic chamber 7 are interconnected. A rotating shaft 8 is rotatably installed inside the hydraulic chamber 7. Four groups of blades 9 are fixedly installed on the outer wall of the rotating shaft 8. The blades 9 are arranged circumferentially on the outer wall of the rotating shaft 8. A driving block 18 is rotatably installed on the rear outer wall of the hydraulic chamber 7. The driving block 18 is fixedly connected to the rotating shaft 8. A scraping plate 15 is arranged at the top of the water inlet tank 5. The rear of the scraping plate 15 and the driving block 18 are connected to each other through a connecting rope 19. A drain pipe 10 is fixedly installed at the bottom of the hydraulic chamber 7.
[0028] After the installation of the vertical column 1, the inclined beam 2 and the photovoltaic module 3 is completed, the staff installs the drainage board 4 under the photovoltaic module 3. And when the photovoltaic bracket is laid for a long distance, the staff connects the bumps 22 on the left side and the notches 23 on the right side of multiple connecting plates 21 to each other. After the connection is completed, the staff rotates the bolt 24 to fixedly connect the connecting plates 21 to each other, so as to ensure the smooth drainage of the drainage board 4. After the installation of the drainage board 4 is completed, when it starts to rain outside, the rainwater flows from the photovoltaic module 3 into the interior of the drainage board 4, and is transported to the left through the diversion groove 20, and enters the interior of the water inlet tank 5 after being filtered by the filter plate 6. The filtered rainwater enters the interior of the hydraulic chamber 7 through the water inlet tank 5. At this time, the blade 9 is slapped by the rainwater, causing the rotating shaft 8 to start to rotate slightly. The rainwater passes through the hydraulic chamber 7 and is discharged to other positions from the drain pipe 10. The rotation of the rotating shaft 8 drives the driving block 18 to rotate. When the driving block 18 rotates, the connecting rope 19 pulls down the scraping plate 15, so that the slider 14 at the bottom of the scraping plate 15 slides along the guide rod 12, and the spring 13 is stretched. When the drainage volume is large, the scraping plate 15 is pulled to the rear of the filter plate 6. And when sundries accumulate on the top of the filter plate 6, the drainage volume becomes smaller, reducing the force on the blade 9, and further causing the elastic potential energy of the spring 13 to drive the scraping plate 15 to move forward, so as to remove the sundries accumulated on the top of the filter plate 6. And after the drainage resumes, the scraping plate 15 is pulled by the connecting rope 19 to reset, preparing for the next cleaning.
[0029] During rainfall, through the induction of the rainwater by the blade 9, the rotating shaft 8 and the driving block 18 rotate together. When the driving block 18 rotates, the connecting rope 19 pulls down the scraping plate 15, so that the scraping plate 15 is pulled to the rear of the filter plate 6. And when sundries accumulate on the top of the filter plate 6, the elastic potential energy of the spring 13 drives the scraping plate 15 to move forward, so as to remove the sundries accumulated on the top of the filter plate 6. Compared with the traditional device, through the setting of the blade 9, when it rains outside, the scraping plate 15 is pulled to the rear of the filter plate 6, and when the drainage volume becomes smaller, the scraping plate 15 automatically removes the sundries on the top of the filter plate 6, effectively ensuring the normal operation of the drainage.
[0030] Wherein, a connecting plate 21 is fixedly installed on the front side of the drainage board 4. A bump 22 is fixedly arranged on the left side of the connecting plate 21, and a notch 23 is formed on the right side of the connecting plate 21. The sizes of the bump 22 and the notch 23 correspond to each other.
[0031] After the installation of the vertical column 1, the inclined beam 2 and the photovoltaic module 3 is completed, the staff installs the drainage board 4 under the photovoltaic module 3. And when the photovoltaic bracket is laid for a long distance, the staff connects the bumps 22 on the left side and the notches 23 on the right side of multiple connecting plates 21 to each other. After the connection is completed, the staff rotates the bolt 24 to fixedly connect the connecting plates 21 to each other, so as to ensure the smooth drainage of the drainage board 4.
[0032] Through the settings of the bumps 22 and notches 23, multiple sets of connecting plates 21 can be connected to each other. Then, bolts 24 are used to fix between the connecting plates 21. Compared with traditional devices, through the mutual splicing between the connecting plates 21, multiple sets of drainage plates 4 can share the same drainage outlet, making the drainage more concentrated and smooth, facilitating the collection of rainwater.
[0033] Among them, a bracket 16 is fixedly installed at the rear of the water inlet tank 5. A roller 17 is rotatably installed inside the bracket 16. One end of a connecting rope 19 is fixedly connected to a driving block 18, and the other end of the connecting rope 19 passes through the top of the roller 17 and is fixedly connected to a scraper 15.
[0034] Responsible for fixing the connecting rope 19 and providing a backward pulling force for the scraper 15.
[0035] Among them, guiding grooves 11 are respectively opened on the left and right sides at the top of the water inlet tank 5. Guide rods 12 are fixedly installed inside the two guiding grooves 11. A slider 14 is sleeved on the outer wall of the guide rod 12, and its top is fixedly connected to the scraper 15.
[0036] When the driving block 18 rotates, the connecting rope 19 pulls the scraper 15 downward, causing the slider 14 at the bottom of the scraper 15 to slide along the guide rod 12, and the spring 13 is stretched.
[0037] Among them, the connecting plates 21 are connected to each other through the bumps 22 and notches 23, and bolts 24 are arranged on the outer wall of the connecting plates 21. One end of the bolt 24 penetrates through the notch 23 and is threadedly sleeved with the bump 22.
[0038] The staff rotates the bolt 24 to fixedly connect the connecting plates 21 to each other, thereby ensuring the smooth drainage of the drainage plate 4.
[0039] Among them, a diversion groove 20 is opened inside the water inlet tank 5, which is responsible for guiding the flow direction of rainwater.
[0040] Among them, the slider 14 is movably installed inside the guiding groove 11, and one end of the slider 14 is elastically connected to the inner wall of the guiding groove 11 through a spring 13.
[0041] When sundries accumulate on the top of the filter plate 6, the drainage volume becomes smaller, reducing the force on the blade 9. Further, the elastic potential energy of the spring 13 drives the scraper 15 to move forward, thereby removing the sundries accumulated on the top of the filter plate 6.
[0042] The working principle and usage process of the present utility model:
[0043] After the installation of the column 1, the inclined beam 2 and the photovoltaic module 3 is completed, the staff installs the drainage board 4 under the photovoltaic module 3, and when the photovoltaic bracket is laid for a long time, the staff connects the protrusions 22 on the left side of the multiple groups of connecting plates 21 and the notches 23 on the right side. After the connection is completed, the staff rotates the bolts 24 to fix the connecting plates 21 to each other, thereby ensuring smooth drainage of the drainage board 4. After the drainage board 4 is installed, when it starts to rain outside, rainwater flows from the photovoltaic module 3 into the interior of the drainage board 4, and is transported to the left through the guide groove 20, and is filtered by the filter plate 6 and flows into the interior of the water inlet tank 5. The filtered rainwater enters the interior of the hydraulic tank 7 through the water inlet tank 5. At this time, the blades 9 are flapped by the rainwater, causing the rotary The driving shaft 8 starts to rotate slightly, and the rainwater passes through the hydraulic tank 7 and is discharged from the drain pipe 10 to other positions. The rotation of the rotating shaft 8 drives the driving block 18 to rotate. When the driving block 18 rotates, the connecting rope 19 pulls the scraper 15 downward, so that the slider 14 at the bottom of the scraper 15 slides along the guide rod 12, and the spring 13 is stretched. When the drainage volume is large, the scraper 15 is pulled to the rear of the filter plate 6, and when debris is accumulated on the top of the filter plate 6, the drainage volume becomes smaller, so that the force on the blade 9 is reduced, and the elastic potential energy of the spring 13 further drives the scraper 15 to move forward, thereby removing the debris accumulated on the top of the filter plate 6, and after the drainage is restored, the scraper 15 is pulled by the connecting rope 19 to reset and prepare for the next cleaning.
