Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, specifically to a tilt-adjustable, light-tracking rooftop photovoltaic panel. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Because PV panels have no moving parts, they can operate for extended periods without any wear and tear. However, during use, due to the fixed installation angle, the PV panel can be partially shaded as the sun rotates, affecting the absorption and conversion of sunlight.

[0003] To overcome the aforementioned shortcomings, an adjustable tilt photovoltaic bracket (publication number CN205829548U) is disclosed. It is suitable for the installation, fixing, and tilt adjustment of photovoltaic panels in photovoltaic power plants. It features a simple and reasonable structure, easy processing, low cost, flexible adjustment, and good stability. The tilt angle of the photovoltaic panel can be adjusted within the range of 15° to 80°, achieving the beneficial effect of tracking sunlight and increasing power generation. It is worthy of widespread application. A tracking solar photovoltaic power generation device (publication number CN209543150U) is also disclosed. A second bracket is located in front of the second electric push rod. The second bracket is rotatably connected to the support plate. The mounting plate is fixed below the second electric push rod with screws, and a protective shell is fixed between the second brackets. A solar tracking sensor can detect changes in the sun's position. The first and second electric push rods can realize the forward and backward rotation and left and right rotation of the solar photovoltaic panel, facilitating the adjustment of the solar photovoltaic panel's position to be perpendicular to the sunlight. It is flexible and convenient to use, improving the working efficiency of the solar photovoltaic panel.

[0004] In both of the aforementioned comparative cases, the institutions adjusted the angle of the photovoltaic panels to increase their contact area with sunlight. However, in actual use, after prolonged use, dust and dirt residue would accumulate on the surface of the photovoltaic panels, affecting their absorption and conversion of light energy. Summary of the Invention

[0005] The purpose of this invention is to provide a tilt-adjustable, light-tracking rooftop photovoltaic panel to solve the problem mentioned in the background art, where the photovoltaic panel is partially blocked when the sun rotates due to the fixed installation angle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tilt-adjustable, light-following roof photovoltaic panel, comprising a mounting frame, a counterweight platform disposed below the mounting frame, and a photovoltaic panel body disposed above the mounting frame; Two first threaded rods are provided on the top left side of the mounting frame, and an adjustment mechanism for the photovoltaic panel to track the light source is provided on the right side of the first threaded rods. The adjustment mechanism includes a servo motor, which is located at the top of the first threaded rod. The upper ends of the outer sides of the two first threaded rods are connected by a belt drive mechanism. A first movable block is threaded to the outer side of each first threaded rod, and a connecting plate is fixedly connected to the right side of the first movable block. A connecting frame is hinged to the right side of the connecting plate. The photovoltaic panel is mounted on the top of the connecting frame. When the connecting plate moves upward, it will drive the connecting frame to change its angle, thereby causing the photovoltaic panel placed above the connecting frame to be driven to deflect at an angle, so that the photovoltaic panel can always be in a state of illumination, which is conducive to better absorption and conversion of light. A movable plate is provided on the left side of the mounting bracket below the connecting plate, and a dust removal mechanism for cleaning the surface of the photovoltaic panel is provided on the right side of the movable plate.

[0007] Furthermore, the bottom end of the first threaded rod extends to the bottom end of the mounting frame. The first threaded rod is equipped with a drive gear via a belt drive mechanism. A driven gear that meshes with the drive gear is installed at the middle position of the bottom end of the mounting frame. The drive gear meshes with the driven gear on one side, thereby enabling the driven gear to drive the entire mounting frame to rotate. This allows the photovoltaic panel to be adjusted in different directions to follow the direction of the sun during use.

[0008] Furthermore, the drive gear is slidably connected to the bottom end of the mounting frame, and the bottom end of the drive gear is rotatably connected to the counterweight platform.

[0009] Furthermore, the bottom end of the connecting frame is slidably connected to the mounting frame, and the connecting frame is located on the right side of the movable plate.

[0010] Furthermore, the dust removal mechanism includes an airbag, which is located on the left side of the movable plate. Nozzles are installed at both ends of the top of the airbag via flexible hoses, and these nozzles are positioned above the photovoltaic panel body. A pressure plate is installed at the lower right end of the connecting frame, and this pressure plate is located on the right side of the movable plate. Gas inside the airbag is delivered to the nozzles via flexible hoses, and the nozzles are used to blow air onto the surface of the photovoltaic panel body to remove dust. This effectively reduces the accumulation of dust on the surface of the photovoltaic panel body, thus preventing dust accumulation from affecting the photovoltaic panel body's ability to convert light energy and increasing the overall applicability during use.

[0011] Furthermore, reset springs are provided at both the front and rear ends of the left side of the movable plate, and the airbag and the movable plate form an elastic structure through the reset springs.

[0012] Furthermore, a collection box is provided on the right side of the mounting frame, and a rainwater collection mechanism is provided inside the collection box. The collection mechanism includes fan blades, which are rotatably connected to the inside of the collection box. Both ends of the fan blades extend to the outside of the collection box and are rotatably connected to a second threaded rod via a belt drive mechanism. The second threaded rod is located on the right side of the top of the mounting frame. A second movable block is threadedly connected to the outside of the second threaded rod, and a cleaning brush is hinged to one side of the second movable block. When the second movable block moves left and right, the bottom end of the cleaning brush will come into contact with the surface of the photovoltaic panel. This allows the dirt on the surface of the photovoltaic panel to be thoroughly cleaned by the combined action of the cleaning brush and rainwater, reducing the amount of dirt on the photovoltaic panel surface. When the fan blades are washed by rainwater, the photovoltaic panel remains fixed, so there will be no situation where the photovoltaic panel is out of position and cannot be cleaned when the cleaning brush is used to clean it. The front end of the second movable block is equipped with a fixing frame, which is connected to the scraper through the bottom end of the fixing frame. The filter screen can filter the collected rainwater, and the collected and filtered rainwater can be sprayed out onto the surface of the photovoltaic panel through the water pump, effectively assisting the nozzle in removing surface dust.

[0013] Furthermore, the bottom end of the cleaning brush is attached to the top end of the photovoltaic panel body, and the length of the cleaning brush is equal to the height of the photovoltaic panel body.

[0014] Furthermore, the inside of the collection box is equipped with a filter screen, and a scraper is installed on the right side of the second movable block via a fixing bracket, with the bottom end of the scraper in contact with the surface of the filter screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The first threaded rod is driven to rotate by the output end of the servo motor. When the first threaded rod rotates, the first movable block is driven and slides up and down on its outside, thereby driving the connecting plate. When the connecting plate moves upward, it will drive the connecting frame to change its angle, thereby causing the photovoltaic panel body placed on the connecting frame to be driven to deflect at an angle, so that the photovoltaic panel body can always be in the state of illumination, which is conducive to better absorption and conversion of light.

[0016] Furthermore, during the rotation of the first threaded rod, the drive gear can be driven to rotate through the belt drive mechanism, so that the drive gear meshes with the driven gear on one side, thereby enabling the driven gear to drive the entire mounting frame to rotate, allowing the photovoltaic panel to be adjusted in different directions to follow the direction of the sun during use.

[0017] Furthermore, when the connecting frame is driven by the connecting plate to change its angle, the squeezing plate on one side of the connecting frame will continuously squeeze the movable plate, causing the airbag on one side of the movable plate to be squeezed and deformed. At the same time, the gas inside the airbag is delivered to the nozzle through the hose, and then the nozzle can be used to blow air to remove dust from the surface of the photovoltaic panel, effectively reducing the accumulation of floating dust on the surface of the photovoltaic panel. This prevents dust accumulation from affecting the photovoltaic panel's ability to convert light energy, and increases the overall applicability during use.

[0018] 2. The second movable block moves left and right outside the second threaded rod. At the same time, a cleaning brush is hinged to one end of the second movable block. When the second movable block moves left and right, the bottom end of the cleaning brush will come into contact with the surface of the photovoltaic panel body. This allows the dirt on the surface of the photovoltaic panel body to be thoroughly cleaned by the cleaning brush and rainwater, reducing the dirt on the surface of the photovoltaic panel body. When the fan blades are washed by rainwater, the photovoltaic panel body remains fixed as a whole. Therefore, when the cleaning brush cleans it, there will be no situation where the position of the photovoltaic panel body shifts and cannot be cleaned.

[0019] Furthermore, a fixing frame is installed at the front end of the second movable block, and the bottom end of the fixing frame is connected to the scraper. The filter screen can filter the collected rainwater, and the collected and filtered rainwater can be sprayed out again by the water pump to clean the surface of the photovoltaic panel body, effectively assisting the nozzle to remove surface dust.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 The technical solution shown addresses the problem that a fixed installation angle of a photovoltaic panel can cause partial shading of the panel as the sun rotates, affecting the absorption and conversion of light energy. This tilt-adjustable, light-tracking rooftop photovoltaic panel discloses an angle adjustment mechanism, including a mounting frame 1. A counterweight 2 is located below the mounting frame 1, and the photovoltaic panel body 3 is located above the mounting frame 1. Two first threaded rods 5 are located on the left side of the top of the mounting frame 1, and an adjustment mechanism for the photovoltaic panel body 3 to track the light source is located on the right side of the first threaded rods 5. The adjustment mechanism includes a servo motor 4, which is located at the top of the first threaded rods 5. The upper ends of the outer sides of the two first threaded rods 5 are connected by a belt drive. The components are connected in the following way: the outer side of the first threaded rod 5 is threaded with a first movable block 6, and the right side of the first movable block 6 is fixedly connected with a connecting plate 7. The right side of the connecting plate 7 is hinged with a connecting frame 8. The photovoltaic panel body 3 is installed on the top of the connecting frame 8. The bottom end of the first threaded rod 5 extends to the bottom end of the mounting frame 1. The first threaded rod 5 is equipped with a drive gear 22 through a belt drive mechanism. The middle position of the bottom end of the mounting frame 1 is equipped with a driven gear 23 that meshes with the drive gear 22. The drive gear 22 is slidably connected to the bottom end of the mounting frame 1, and the bottom end of the drive gear 22 is rotatably connected to the counterweight 2. The bottom end of the connecting frame 8 is slidably connected to the mounting frame 1, and the connecting frame 8 is located on the right side of the movable plate 11.

[0024] In this example, a light sensor is used to control the rotation of the servo motor 4, which in turn allows the servo motor 4 to adjust its rotation according to different needs. By installing the photovoltaic panel body 3 and the connecting plate 7 together, the output end of the servo motor 4 drives the first threaded rod 5 to rotate. When the first threaded rod 5 rotates, the first movable block 6 is driven and slides up and down on its outside, thereby driving the connecting plate 7. When the connecting plate 7 moves upward, it will drive the connecting frame 8 to change its angle, thereby causing the photovoltaic panel body 3 placed on the connecting frame 8 to be driven to deflect at an angle, so that the photovoltaic panel body 3 can always be in a state of illumination, which is conducive to better absorption and conversion of light.

[0025] Meanwhile, during the rotation of the first threaded rod 5, the active gear 22 can be driven to rotate through the belt transmission mechanism, so that the active gear 22 meshes with the driven gear 23 on one side, thereby enabling the driven gear 23 to drive the entire mounting frame 1 to rotate, so that the photovoltaic panel body 3 can be adjusted to different angles to follow the direction of the sun during use.

[0026] Example 2: like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 9 The technical solution shown is based on Embodiment 1. In order to solve the problem that dust residue is easy to accumulate on the surface of the photovoltaic panel body 3 during use, the tilt-adjustable tracking light-oriented roof photovoltaic panel discloses a dust removal mechanism. A movable plate 11 is provided on the left side of the mounting frame 1 below the connecting plate 7, and a dust removal mechanism for cleaning the surface of the photovoltaic panel body 3 is provided on the right side of the movable plate 11. The dust removal mechanism includes an airbag 9, which is located on the left side of the movable plate 11. The front and rear ends of the top of the airbag 9 are equipped with nozzles 13 through hoses, and the nozzles 13 are located above the photovoltaic panel body 3. A pressing plate 12 is installed at the lower right end of the connecting frame 8, and the pressing plate 12 is located on the right side of the movable plate 11. The front and rear ends of the left side of the movable plate 11 are equipped with return springs 10, and the airbag 9 and the movable plate 11 form an elastic structure through the return springs 10.

[0027] In this example, when the connecting frame 8 is driven by the connecting plate 7 to change its angle, the pressing plate 12 on one side of the connecting frame 8 will continuously press the movable plate 11, causing the airbag 9 on one side of the movable plate 11 to be compressed and deformed. At the same time, the gas inside the airbag 9 is delivered to the nozzle 13 through the hose. Then, the nozzle 13 can be used to blow air to remove dust from the surface of the photovoltaic panel body 3, effectively reducing the accumulation of floating dust on the surface of the photovoltaic panel body 3.

[0028] Furthermore, when the airbag 9 is compressed, the return spring 10 will be simultaneously stressed and shorten in length. When the connecting frame 8 is reset, the airbag 9 loses its compression, and the return spring 10 will automatically push the movable plate 11 to reset its position. The airbag 9 can automatically deliver gas into the interior through the air pump due to the reset of the movable plate 11.

[0029] Example 3: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 The technical solution shown addresses the problem that surface dirt on the photovoltaic panel 3, which is exposed to the elements for extended periods, cannot be thoroughly removed by dust removal mechanisms alone. This tilt-adjustable, light-following rooftop photovoltaic panel discloses a collection mechanism. A collection box 14 is located on the right side of the mounting frame 1, and a rainwater collection mechanism is installed inside the collection box 14. The collection mechanism includes fan blades 15, which are rotatably connected to the inside of the collection box 14. Both ends of the fan blades 15 extend to the outside of the collection box 14 and are rotatably connected to a second thread via a belt drive mechanism. The second threaded rod 16 is located on the right side of the top of the mounting bracket 1. The external thread of the second threaded rod 16 is connected to the second movable block 17. A cleaning brush 18 is hinged to one side of the second movable block 17. The bottom end of the cleaning brush 18 is in contact with the top end of the photovoltaic panel body 3. The length of the cleaning brush 18 is equal to the height of the photovoltaic panel body 3. A filter screen 21 is provided inside the collection box 14. A scraper 20 is installed on the right side of the second movable block 17 through the fixing bracket 19. The bottom end of the scraper 20 is in contact with the surface of the filter screen 21.

[0030] In this example, rainwater is collected by the collection box 14 during rain. The rainwater causes the fan blades 15 to rotate due to the impact. As the fan blades 15 rotate, they drive the second threaded rod 16 to rotate via a belt drive mechanism. The second threaded rod 16 is threadedly connected to the second movable block 17 during rotation, allowing the second movable block 17 to move left and right outside the second threaded rod 16. Simultaneously, a cleaning brush 18 is hinged to one end of the second movable block 17. When the second movable block 17 moves left and right, the bottom end of the cleaning brush 18 comes into contact with the surface of the photovoltaic panel body 3, thereby removing dirt from the surface of the photovoltaic panel body 3. The cleaning brush 18 works in conjunction with rainwater to thoroughly clean the surface of the photovoltaic panel 3, reducing dirt on the surface. When the fan blades 15 are washed by rainwater, the photovoltaic panel 3 remains fixed, so the cleaning brush 18 will not cause the photovoltaic panel 3 to shift and become unclean. At the same time, a fixing frame 19 is installed at the front end of the second movable block 17, and the bottom end of the fixing frame 19 is connected to the scraper 20. The filter screen 21 can filter the collected rainwater, and the collected and filtered rainwater can be sprayed out again by the water pump to clean the surface of the photovoltaic panel 3, effectively assisting the nozzle 13 in removing surface dust.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
