Description

Technical Field

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

[0002] In the prior art, in order to make full use of solar energy resources, solar panels are installed on lakes formed in some coal mining subsidence areas or lakes formed by quarrying. During the installation process of the solar panels on the lake, a floating base is usually selected, and then they are connected and fixed one by one through a simple bracket. Such solar panels do not have an angle adjustment function; moreover, the conventional base is a simple series connection of square buoys, and its stability is poor, making it difficult to meet the requirements of solar panels with adjustable angles. Summary of the Invention

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

[0004] In a first aspect, the present invention provides an adjustable-angle solar panel mounting base for fixing an adjustable-angle solar panel mounting bracket. The mounting base includes a buoyancy frame and adjustment boxes. Two of the adjustment boxes are symmetrically arranged in the buoyancy frame and rotatably connected thereto. The top of the adjustment box communicates with 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 transverse surface of the adjustment box and is provided with a sealing ring around its periphery. When the solar panel is tilted, the telescopic member in the adjustment box closer to the tilted side squeezes out the water inside it to keep the entire mounting base balanced.

[0005] Furthermore, the mounting base further includes adjustment components. 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 limit track and ejecting structures symmetrically arranged on the left and right sides of the limit track. The connecting roller is rotatably embedded in the limit track. Both sides of the left and right of the limit track are provided with inwardly protruding convex parts, and the convex parts are located above or / and below the connecting roller. The ejecting structure includes a moving rod, and the moving rod is movably abutted against the convex part. By moving the moving rod away from the convex part and then adjusting the gravity of the buoyancy box, the limit track will move upward or downward under the action of the buoyancy of the adjustment box.

[0006] Furthermore, the ejection structure further includes a housing, a return spring, a telescopic motor, and a positioning rod. The housing is connected to the adjustment box. One end of the moving rod is embedded in the side wall of the housing and connected to the return spring. A positioning hole is provided on the moving rod. The positioning rod vertically passes through the positioning hole. The lateral surface area of the positioning rod is smaller than the lateral surface area of the positioning hole. A convex block is provided on the positioning rod. Moving the positioning rod to embed the convex block into the positioning hole realizes the movement limit of the moving rod.

[0007] Furthermore, the limiting track is a closed enclosure composed of metal, and its shape is the same as the shape after overlapping several circles with the same diameter as the connecting roller. The overlapping part of adjacent circles is the convex part.

[0008] Furthermore, a movable leaf is provided to cover the opening. The movable leaf is rotatably connected to the opening and its rotation angle is between 30-45°.

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

[0010] Furthermore, the mounting bracket further includes a buffer assembly. A resisting plate and a connecting portion for connecting the rotating rod are provided at the top of the mounting base. Two resisting plates are respectively arranged on the left and right sides of the rotating rod. The buffer assembly is arranged between the rotating rod and the resisting plate, abuts against the side wall of the resisting 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 portion; 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 the side of the L-shaped connecting rod parallel to the resisting plate and abuts against the resisting plate. The L-shaped connecting rod swings around the bottom rod under the action of the rotating rod.

[0012] By adopting the above technical solutions, the beneficial effects of the present invention are: 1. The present invention ensures that the entire installation base can float on the water surface by setting a buoyancy frame, and then sets an adjustment box in the buoyancy frame. The two adjustment boxes are used to adjust their own weight following the gravity change of the solar panel after the angle is adjusted, 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 is adjustable by setting an adjustment component, and the position of the connecting roller in the limit track is limited by setting a limit track with a certain elasticity in conjunction 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 limit track 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. The structure is simple and the functions are diverse.

[0013] 2. The present invention sets a fixed panel as the fixing surface of the solar panel, and then sets a driving motor thereunder, 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. The buffer component is set to increase the resistance of the rotating rod when it swings, so that the angle adjustment process is smoother.

Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present invention, but not to limit the present invention.

[0023] Referring to Figures 1-8 , in the first aspect, the present invention provides an adjustable-angle mounting base for a solar panel, which is used to fix an adjustable-angle mounting bracket for a solar panel.

[0024] The mounting base includes a buoyancy frame 1, adjustment boxes 2, and adjustment components 3. The two adjustment boxes 2 are symmetrically arranged inside the buoyancy frame 1 and are rotatably connected thereto. The rotatable connection can be achieved by providing bearings at the connection between the two. The top of the adjustment box 2 communicates with the atmosphere, and the communication method can be punching or directly using a box body without a top structure. Inside the adjustment box 2, there are telescopic members 21 and a thrust plate 22. The telescopic members 21 are electrically controlled to be length-adjustable. A number of openings 23 are provided at the bottom of the adjustment box 2, and the openings 23 are located on the side walls. When necessary, a hinge 24 is provided on its surface, and the hinge 24 is rotatably connected to the opening 23 and an existing rotational limit structure is provided at the connection between the two. The rotational limit structure enables its rotation angle to be between 30 - 45°. The hinge 24 swings slightly with the inflow and outflow of water to prevent impurities from entering the box. The telescopic members 21 are arranged at the top of the adjustment box 2 and their telescopic ends are connected to the thrust plate 22. The thrust plate 22 covers the transverse surface of the adjustment box 2 and a sealing ring is provided around its perimeter. A seal is formed between the perimeter of the thrust plate 22 and the inside of the box. 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 changes. At this time, to ensure the balance of the support base, the telescopic members 21 inside the adjustment box 2 closer to the tilted side are moved, so that the thrust plate 22 squeezes out the water inside the adjustment box 2. At this time, the self-weight of the box can be reduced, causing one side of the buoyancy frame 1 to float towards the tilted end, so as to increase the local support force of the solar panel after the balance angle changes.

[0025] To improve the ability of the mounting 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 components 3 enable the adjustment box 2 to have the function of height adjustment. When facing strong wind weather, the two adjustment boxes 2 can be moved upward until they abut against the bottom of the fixed panel 4, increasing the connection strength between them and the mounting base. When the water level is too low, the two adjustment boxes 2 can be moved downward so that they contact the water bottom surface, increasing the stability of the mounting base. Specifically: Connecting rollers 11 are symmetrically arranged on the inner circle of the buoyancy frame 1. The connecting rollers 11 can be cylindrical and are equipped with bearings. The adjustment component 3 includes a limit track 31 and ejecting structures 32 symmetrically arranged on the left and right sides of the limit track 31. The connecting rollers 11 are rotatably embedded in the limit track 31. Convex portions 311 protruding inward are provided on both the left and right sides of the limit track 31. The convex portions 311 are located above and / or below the connecting rollers 11. In this embodiment, specifically: Refer to Figure 8, the limiting track 31 is a closed enclosure made of metal, and its shape is the same as the shape after overlapping several circles with the same diameter as the connecting roller 11. The overlapping part of adjacent circles is the convex part 311. At this time, there are two convex parts 311 on one side and are respectively located on the upper and lower sides of the connecting roller 11. The ejecting 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 adjusting box 2. One end of the moving rod 321 is embedded in the side wall of the housing 322 and connected to the return spring 323. The moving rod 321 is kept in contact with the limiting track 31 under the action of the return spring 323. To limit the movement of the moving rod 321, a positioning hole is provided on the moving rod 321. The positioning rod 325 vertically passes through the positioning hole, and a convex block 3251 is provided on the positioning rod 325. Moving the positioning rod 325 makes the convex block 3251 embed into the positioning hole to realize the movement limit of the moving rod 321. To enable the limiting track 31 to switch the connection point of the connecting roller 11 under the changes of gravity and buoyancy, the lateral area of the positioning rod 325 is made smaller than the lateral area of the positioning hole, leaving room for the extrusion of the moving rod 321. When the moving rod 321 leaves the convex part 311 and then the gravity of the buoyancy box is adjusted, the limiting track 31 will push the connecting roller 11 to move up or down under the action of the buoyancy of the adjusting box 2.

[0026] In a second aspect, the present invention provides an adjustable-angle solar panel mounting bracket, which is used to be fixed on the above-mentioned mounting base. The mounting bracket includes a fixed panel 4, a rotating rod 5, a biaxial driving motor 6 and a driving gear 7. Two rotating rods 5 are symmetrically arranged below the fixed panel 4 and one end is rotatably connected to the mounting base. The biaxial driving motor 6 is arranged below the fixed panel 4. Two driving gears 7 are respectively rotatably arranged on the side walls of the rotating rods 5 and connected to the biaxial driving motor 6. Two gear members 12 are symmetrically arranged above the mounting base. The driving gear 7 meshes with the gear member 12. Starting the biaxial driving motor 6 makes the driving gear 7 drive the rotating rod 5 to swing.

[0027] To increase the swinging resistance of the rotating rod 5, buffer components 8 are arranged on both sides thereof. The top of the mounting base is provided with a resisting plate 10 and a connecting part 9 for connecting the rotating rod 5. Two resisting plates 10 are respectively arranged on the left and right sides of the rotating rod 5. The buffer components 8 are arranged between the rotating rod 5 and the resisting plate 10, abutting against the side wall of the resisting plate 10 and can swing with the rotating rod 5. The buffer component 8 specifically includes: a bottom rod 81, an L-shaped connecting rod 82 and a roller 83. The bottom rod 81 is connected to the connecting part 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 the side of the L-shaped connecting rod 82 parallel to the resisting plate 10 and abuts against the resisting plate 10. The roller 83 is preferably made of an elastic material. The L-shaped connecting rod 82 swings around the bottom rod 81 under the action of the rotating rod 5.

[0028] Working principle: Adjust the relative positions of the adjustment box 2 and the buoyancy box according to the weather and water level conditions. After the installation base is stable, move the positioning rod 325 so that the bump 3251 is embedded in the positioning hole to determine the connection point between the adjustment box 2 and the buoyancy box. When adjusting the angle of the solar panel each time, adjust the water volume in the corresponding side adjustment box 2 according to the inclination of the installation base, so as to adapt to the adjustment requirements of different angles.
