Description

Technical Field

[0001] The present invention relates to the technical field of solar energy installation, and in particular to an angle-adjustable solar panel installation bracket and an installation base thereof. Background Art

[0002] To fully utilize solar energy resources, existing solar panels are installed on lakes formed by coal mining or quarrying. These panels are typically installed on a floating base, each connected and secured individually using simple brackets. These panels lack angle adjustment capabilities. Furthermore, conventional bases consist of simple, series-connected square buoys, which are unstable and difficult to adapt to the requirements of angle-adjustable solar panels. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an angle-adjustable solar panel mounting bracket and its mounting base, which have the advantages of being able to change the center of gravity with the adjustment angle, better stability and simpler structure.

[0004] In a first aspect, the present invention provides an angle-adjustable solar panel mounting base, which is used to fix an angle-adjustable solar panel mounting bracket. The mounting base includes a buoyancy frame and an adjustment box. Two adjustment boxes are symmetrically arranged within the buoyancy frame and rotatably connected thereto. The top of the adjustment box is open to the atmosphere. The adjustment box includes a telescopic member and a thrust plate. The bottom of the adjustment box is provided with a plurality of openings. The telescopic member is arranged at the top of the adjustment box and its telescopic end is connected to the thrust plate. The thrust plate covers the lateral surface of the adjustment box and is surrounded by a sealing ring. When the solar panel is tilted, the telescopic member in the adjustment box near the tilted side squeezes out the water inside, thereby maintaining the balance of the entire mounting base.

[0005] Furthermore, the mounting base also includes an adjustment component, and two of the adjustment components are respectively arranged on the left and right sides of the adjustment box; the inner ring of the buoyancy frame is symmetrically provided with connecting rollers; the adjustment component includes a limiting rail and an ejection structure symmetrically arranged on the left and right sides of the limiting rail, and the connecting roller is rotatably embedded in the limiting rail, and the left and right sides of the limiting rail are provided with inwardly protruding protrusions, which are located above or / and below the connecting roller, and the ejection structure includes a moving rod, which is movably abutted against the protrusion, so that the moving rod leaves the protrusion, and then adjusts the gravity of the buoyancy box, and the limiting rail will move up or down under the action of the buoyancy of the adjustment box.

[0006] Furthermore, the ejection structure also includes a shell, a return spring, a telescopic motor and a positioning rod. The shell is connected to the adjustment box. One end of the moving rod is embedded in the side wall of the shell and connected to the return spring. A positioning hole is provided on the moving rod. The positioning rod passes vertically through the positioning hole. The transverse surface area of the positioning rod is smaller than the transverse surface area of the positioning hole. A protrusion is provided on the positioning rod. Moving the positioning rod causes the protrusion to be embedded in the positioning hole to realize the movement limit of the moving rod.

[0007] Furthermore, the limiting track is a closed enclosure made of metal, and its shape is consistent with the shape of a plurality of circles with the same diameter as the connecting roller overlapped, and the overlapping portion of adjacent circles is the convex portion.

[0008] Furthermore, the opening is covered with a hinge, which is rotatably connected to the opening and has a rotation angle between 30-45 degrees.

[0009] In a second aspect, the present invention provides an angle-adjustable solar panel mounting bracket, which is fixed to the mounting base described above, and includes a fixed panel, a rotating rod, a dual-axis drive motor and a driving gear. The two rotating rods are symmetrically arranged below the fixed panel and one end is rotatably connected to the mounting base. The dual-axis drive motor is arranged below the fixed panel. The two driving gears are respectively rotatably arranged on the side walls of the rotating rods and are connected to the dual-axis drive motor. Two gear parts are symmetrically arranged above the mounting base, and the driving gears are engaged with the gear parts. Starting the dual-axis drive motor causes the driving gears to drive the rotating rods to swing.

[0010] Furthermore, the mounting bracket also includes a buffer assembly, and the top of the mounting base is provided with a support plate and a connecting portion for connecting to the rotating rod, the two support plates are respectively arranged on the left and right sides of the rotating rod, and the buffer assembly is arranged between the rotating rod and the support plate, which abuts against the side wall of the support plate and can swing with the rotating rod.

[0011] Furthermore, the buffer assembly includes a bottom rod, an L-shaped connecting rod and a roller, the bottom rod is connected to the connecting part; one end of the L-shaped connecting rod is rotatably connected to the bottom rod, and the other end is connected to the rotating rod; the roller is sleeved on a side of the L-shaped connecting rod parallel to the abutment plate and abuts against the abutment plate, and the L-shaped connecting rod swings around the bottom rod under the action of the rotating rod.

[0012] By adopting the above technical solution, the beneficial effects of the present invention are:

[0013] 1. The present invention ensures that the entire mounting base can float on the water surface by setting a buoyancy frame, and then sets an adjustment box in the buoyancy frame, and uses the two adjustment boxes to adjust their own weight following the gravity change of the solar panel after angle adjustment, thereby increasing the stability of the entire base and making it more adaptable to the solar panel with a changed gravity position. The structure is simple and maintenance is convenient. The height of the adjustment box can be adjusted by setting an adjustment component, and the position of the connecting roller in the limiting track is limited by setting a limiting rail with a certain elasticity in combination with the ejection structure. When the ejection structure can be loosened, the adjustment box rises or falls under the interaction of buoyancy and gravity, driving the limiting rail to move on the connecting roller. In windy weather, the adjustment box can be raised to support the solar panel to increase its stability; when the water level drops, the adjustment box can be lowered to serve as the main support force. The structure is simple and the functions are diverse.

[0014] 2. The present invention sets a fixed panel as the fixing surface of the solar panel, and then sets a driving motor underneath it, so that the structure of the entire panel is more compact and more adaptable to installation points with limited space. The driving device located in the middle position is more adaptable to the height adjustment of the two adjustment boxes; by setting a buffer component to increase the resistance of the rotating rod when it swings, the angle adjustment process is smoother.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0045] Reference Figures 1-8 In a first aspect, the present invention provides an angle-adjustable solar panel mounting base, which is used to fix an angle-adjustable solar panel mounting bracket.

[0046] The mounting base includes a buoyancy frame 1, an adjustment box 2, and an adjustment assembly 3. The two adjustment boxes 2 are symmetrically arranged in the buoyancy frame 1 and are rotatably connected thereto. The rotatable connection can be achieved by setting a bearing at the connection between the two. The top of the adjustment box 2 is connected to the atmosphere, and the connection can be achieved by punching a hole or directly using a box without a top structure. The adjustment box 2 includes a telescopic member 21 and a thrust plate 22. The telescopic member 21 is electrically controlled to be retractable in length. The bottom of the adjustment box 2 is provided with a plurality of openings 23, which are arranged on the side wall. If necessary, the surface of the opening 23 is covered with a hinge 24. The hinge 24 is rotatably connected to the opening 23 and an existing rotation limit structure is provided at the connection between the two. The rotation limit structure allows its rotation angle to be between 30-45°. The hinge 24 swings slightly with the flow of water in and out to prevent impurities from entering the box. A telescopic member 21 is located at the top of the regulating box 2, and its telescopic end is connected to a thrust plate 22. The thrust plate 22 covers the lateral surface of the regulating box 2 and is surrounded by a sealing ring. The thrust plate 22 is sealed around the box body. Pushing the thrust plate 22 can change the pressure inside the box and thus adjust the water volume inside the box. When the solar panel tilts, its balance will change. At this time, to ensure the balance of the support base, the telescopic member 21 in the regulating box 2 closer to the tilted side is moved, causing the thrust plate 22 to squeeze out the water inside the regulating box 2. This reduces the weight of the box, causing it to drive one side of the buoyancy frame 1 upward toward the tilted end, thereby increasing the local support force of the solar panel after the balance angle changes.

[0047] In order to improve the ability of the installation base to cope with different climatic environments, two adjustment components 3 are respectively arranged on the left and right sides of the adjustment box 2. The adjustment component 3 enables the adjustment box 2 to have a height-adjustable function. When facing strong winds, the two adjustment boxes 2 can be moved up until they abut against the bottom of the fixed panel 4, thereby increasing the connection strength with the installation base; when the water level is too low, the two adjustment boxes 2 can be moved down so that they contact the bottom of the water, thereby increasing the stability of the installation base. Specifically: the inner ring of the buoyancy frame 1 is symmetrically provided with a connecting roller 11, which can be cylindrical and equipped with a bearing; the adjustment component 3 includes a limiting rail 31 and a ejection structure 32 symmetrically arranged on the left and right sides of the limiting rail 31, the connecting roller 11 is rotatably embedded in the limiting rail 31, and the left and right sides of the limiting rail 31 are provided with an inwardly protruding protrusion 311, and the protrusion 311 is located above or / and below the connecting roller 11. In this embodiment, specifically: refer to Figure 8 The limiting track 31 is a closed metal enclosure, shaped like the overlapping of several circles with the same diameter as the connecting roller 11. The overlapping portion of adjacent circles forms a protrusion 311. In this case, there are two protrusions 311 on a single side, one located on the upper and lower sides of the connecting roller 11. The ejection structure 32 includes a moving rod 321, a housing 322, a return spring 323, a telescopic motor 324, and a positioning rod 325. The housing 322 is connected to the adjustment box 2. One end of the moving rod 321 is embedded in the side wall of the housing 322 and connected to a return spring 323. The return spring 323 maintains the moving rod 321 in contact with the limiting rail 31. To limit the movement of the moving rod 321, a positioning hole is provided in the moving rod 321. A positioning rod 325 extends perpendicularly through the positioning hole. A protrusion 3251 is provided on the positioning rod 325. The positioning rod 325 is moved so that the protrusion 3251 engages with the positioning hole, thereby limiting the movement of the moving rod 321. To enable the limiting rail 31 to switch the connection point of the connecting roller 11 in response to changes in gravity and buoyancy, the transverse surface area of the positioning rod 325 is smaller than that of the positioning hole, leaving room for the moving rod 321 to move. By removing the moving rod 321 from the protrusion 311 and adjusting the gravity of the buoyancy box, the limiting rail 31 will displace the connecting roller 11 upward or downward under the buoyancy of the adjustment box 2.

[0048] In a second aspect, the present invention provides an angle-adjustable solar panel mounting bracket for fixing to the mounting base described above. The mounting bracket includes a fixed panel 4, a rotating rod 5, a dual-axis drive motor 6, and a driving gear 7. Two rotating rods 5 are symmetrically arranged below the fixed panel 4 and are rotatably connected to the mounting base at one end. The dual-axis drive motor 6 is arranged below the fixed panel 4. Two driving gears 7 are rotatably arranged on the side walls of the rotating rods 5 and are connected to the dual-axis drive motor 6. Two gear members 12 are symmetrically arranged above the mounting base. The driving gears 7 engage with the gear members 12. When the dual-axis drive motor 6 is activated, the driving gears 7 drive the rotating rods 5 to swing.

[0049] To increase the swing resistance of the rotating rod 5, buffer assemblies 8 are provided on both sides thereof. Abutment plates 10 and a connecting portion 9 for connecting to the rotating rod 5 are provided on the top of the mounting base. Two abutment plates 10 are provided on the left and right sides of the rotating rod 5, respectively. The buffer assembly 8 is provided between the rotating rod 5 and the abutment plates 10, abutting against the sidewalls of the abutment plates 10 and capable of swinging along with the rotating rod 5. The buffer assembly 8 specifically comprises a bottom rod 81, an L-shaped connecting rod 82, and a roller 83. The bottom rod 81 is connected to the connecting portion 9. One end of the L-shaped connecting rod 82 is rotatably connected to the bottom rod 81, and the other end is connected to the rotating rod 5. The roller 83 is sleeved on a side of the L-shaped connecting rod 82 parallel to the abutment plates 10 and abuts against the abutment plates 10. The roller 83 is preferably made of an elastic material. Under the action of the rotating rod 5, the L-shaped connecting rod 82 swings around the bottom rod 81.

[0050] Working Principle: The relative position of the regulating tank 2 and the buoyancy tank is adjusted based on weather and water level conditions. Once the mounting base is stable, the positioning rod 325 is moved so that the protrusion 3251 engages the positioning hole, thereby confirming the connection point between the regulating tank 2 and the buoyancy tank. Each time the solar panel angle is adjusted, the water volume in the corresponding regulating tank 2 is adjusted based on the inclination of the mounting base to accommodate different angle adjustments.
