Description

Technical Field

[0001] This utility model relates to the field of solar cell module technology, and specifically discloses a solar cell module device that is easy to adjust the angle. Background Technology

[0002] Solar cell modules are the core devices that convert solar energy into electrical energy. They mainly consist of solar cells, EVA film, glass cover, backsheet, frame, and junction box. Their working principle is based on the photoelectric effect: photons in sunlight excite electron-hole pairs within the cell, the PN junction electric field separates charge carriers to create a potential difference, electrons are collected through metal electrodes and output as direct current (DC), which is then converted into alternating current (AC) by an inverter to supply power. Maximum power output occurs when sunlight shines perpendicularly onto the surface of the solar cell; therefore, the angle of the solar cell module needs to be adjusted to correspond to the angle of sunlight.

[0003] Chinese patent CN101159419B discloses a mounting bracket for solar cell modules. The solar cell module is plate-shaped, and pin seats are fixed on the slide, the middle of the lower surface of the solar cell module, and the base of the lead screw end away from the handwheel. The lower edge of the solar cell module is hinged to the pin seat on the base of the lead screw end away from the handwheel by means of a pin shaft. A connecting rod is provided between the solar cell module and the slide. The two ends of the connecting rod are hinged to the pin seat on the slide and the pin seat in the middle of the lower surface of the solar cell module by means of pin shafts, respectively. First, the handwheel is turned to rotate the lead screw, which drives the nut and the slide that is integrated with the nut to move. Then, by pushing and pulling the connecting rod, the solar cell module rotates around the hinge point on its lower edge, thereby realizing the angle adjustment between the solar cell module and the sunlight.

[0004] With the rapid development of technology, the aforementioned patents have certain limitations in practical applications. Firstly, the angle adjustment of solar cell modules via the push-pull linkage can only be achieved within a single direction, while the angle of sunlight exposure is wide, making it unable to fully adapt to changes in sunlight and resulting in insufficient adjustment flexibility. Secondly, because the solar cell modules are fixedly connected to the pin base, disassembling, replacing, or maintaining the solar cell modules is very inconvenient. Therefore, a solar cell module device that facilitates angle adjustment is needed to solve this problem. Utility Model Content

[0005] This invention proposes a solar cell module device that facilitates angle adjustment, which improves the range of angle adjustment of the solar cell module to enhance its flexibility of use and make it fully adaptable to changes in the angle of sunlight; and it also facilitates the disassembly, replacement, or maintenance of the solar cell module.

[0006] This utility model is implemented as follows: a solar cell module device with an adjustable angle includes a base and a solar cell module. The outer edge of the solar cell module has a frame. A steering plate is provided above the base. A support platform is installed on the upper end of the steering plate. An L-shaped rod is movably connected to the upper side of the support platform through a hinge. A positioning frame is installed at the other end of the L-shaped rod. A movable platform is slidably connected to the upper side of the steering plate through a slide rail. A connecting plate is installed inside the positioning frame. A connecting rod is movably connected between the movable platform and the connecting plate through two hinges. A drive mechanism is provided on the upper side of the steering plate.

[0007] The upper end of the base is rotatably connected to a steering column that is fixedly connected to the steering plate, and a locking mechanism is provided on the upper side of the base.

[0008] The locking mechanism includes a threaded post fixedly connected to the upper end of the base. The outer wall of the threaded post is threadedly connected to an internal threaded cylinder. Limiting holes are opened on both the left and right sides of the lower end face of the steering plate. A limiting post extending into the right limiting hole is installed at the upper end of the internal threaded cylinder.

[0009] The outer wall of the frame fits against the inner wall of the positioning frame. The upper end of the positioning frame has two slots distributed front and back. Limiting plates passing through the slots are installed on both the front and back sides of the frame. Horizontal plates are fixedly connected to both the front and back sides of the positioning frame. Vertical plates are fixedly connected to the upper ends of the two horizontal plates. Screws are rotatably connected to the opposite sides of the two vertical plates. The outer walls of the two screws are threaded with translation plates that slide with the horizontal plates via slide rails. Limiting grooves that fit the limiting plates are opened through the outer walls of the two translation plates. Handwheels that pass through the vertical plates are fixedly connected to the opposite sides of the two screws.

[0010] As a preferred embodiment of the solar cell module device of this utility model that facilitates angle adjustment, the driving mechanism includes two vertical plates fixedly connected to the upper end of the steering plate. A lead screw is rotatably connected between the two vertical plates, passing through the moving platform and threadedly connected thereto. A driving frame is installed at the left end of the left vertical plate. A worm gear is rotatably connected inside the driving frame. A worm wheel is meshed with the outer wall of the worm gear. A transmission shaft passing through the left vertical plate is fixedly connected between the worm wheel and the lead screw. A handwheel extending to the outside of the driving frame is installed at the upper end of the worm gear.

[0011] As a preferred embodiment of the solar cell module device of this utility model that facilitates angle adjustment, a rectangular frame that fits against the lower end of the frame is installed inside the positioning frame.

[0012] As a preferred embodiment of the solar cell module device of this utility model that facilitates angle adjustment, guide cones are provided on the opposite sides of the two limiting plates.

[0013] As a preferred embodiment of the solar cell module device of this utility model that facilitates angle adjustment, the two screws are respectively rotatably connected to the front and rear sides of the positioning frame on opposite sides.

[0014] As a preferred embodiment of the solar cell module device of this utility model that facilitates angle adjustment, the upper end of the base is provided with an annular groove, and an annular slider that is fixedly connected to the lower end of the steering column is slidably connected inside the annular groove.

[0016] The beneficial effects of this utility model are:

[0017] When installing solar panels, the outer wall of the frame is aligned with the inner wall of the positioning frame to position the solar panels. Two limiting plates then enter the two slots, and two sliding plates move relative to each other until the two limiting plates pass through the two limiting slots. This restricts the movement of the solar panels and the frame, completing the installation of the solar panels. When the two limiting plates and two guide cones disengage from the two limiting slots, the solar panels and the frame can be easily removed from the positioning frame, facilitating the disassembly, replacement, or maintenance of the solar panels.

[0018] The drive mechanism moves the moving platform to the right, causing the positioning frame and solar panel to rotate clockwise around the hinge axis on the support platform. This increases the tilt angle of the solar panel. Conversely, when the moving platform moves to the left, the tilt angle decreases, allowing adjustment of the solar panel's angle. When the sunlight angle is in the opposite direction, the limiting post disengages from the limiting hole, releasing the restriction on the steering plate. Rotating the steering plate 180 degrees then causes the solar panel to rotate 180 degrees as well, allowing the limiting post to enter another limiting hole, preventing the steering plate from rotating. At this point, the tilted surface of the solar panel faces the opposite side. Adjusting the tilt angle of the solar panel in the same way allows it to adapt to sunlight exposure. This method increases the range of solar panel angle adjustment, enhancing usability and enabling it to fully adapt to changes in sunlight angle. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4 A solar cell module device with adjustable angle includes a base 1 and a solar cell module 2. The outer edge of the solar cell module 2 has a frame 3. A steering plate 4 is provided above the base 1. A support platform 5 is installed on the upper end of the steering plate 4. An L-shaped rod 6 is movably connected to the upper side of the support platform 5 through a hinge. A positioning frame 7 is installed at the other end of the L-shaped rod 6. A movable platform 8 is slidably connected to the upper side of the steering plate 4 through a slide rail. A connecting plate 9 is installed inside the positioning frame 7. A connecting rod 10 is movably connected between the movable platform 8 and the connecting plate 9 through two hinges. A drive mechanism is provided on the upper side of the steering plate 4.

[0027] The upper end of the base 1 is rotatably connected to a steering column 11 that is fixedly connected to the steering plate 4, and a locking mechanism is provided on the upper side of the base 1.

[0028] The locking mechanism includes a threaded post 12 fixedly connected to the upper end of the base 1. The outer wall of the threaded post 12 is threadedly connected to an inner threaded cylinder 13. Limiting holes 14 are opened on both the left and right sides of the lower end face of the steering plate 4. A limiting post 15 extending into the right limiting hole 14 is installed at the upper end of the inner threaded cylinder 13.

[0029] The outer wall of the frame 3 fits into the inner wall of the positioning frame 7. The upper end of the positioning frame 7 has two slots 17 distributed front and back. Limiting plates 18 passing through the slots 17 are installed on both the front and back sides of the frame 3. Horizontal plates 19 are fixedly connected to both the front and back sides of the positioning frame 7. Vertical plates 20 are fixedly connected to the upper ends of the two horizontal plates 19. Screws 21 are rotatably connected to the opposite sides of the two vertical plates 20. The outer walls of the two screws 21 are threadedly connected to translation plates 22 that are slidably connected to the horizontal plates 19 via slide rails. Limiting grooves 23 that are adapted to the limiting plates 18 are opened through the outer walls of the two translation plates 22. Handwheels that pass through the vertical plates 20 are fixedly connected to the opposite sides of the two screws 21.

[0030] In this embodiment: when installing the solar cell module 2, the solar cell module 2, together with the frame 3, is inserted into the interior of the positioning frame 7 until the frame 3 contacts the rectangular frame 16. Since the outer wall of the frame 3 fits against the inner wall of the positioning frame 7, the installation position of the solar cell module 2 can be positioned. At the same time, the two limiting plates 18 will enter the interior of the two slots 17. Then, the two screws 21 are rotated by the two handwheels respectively. Due to the limiting effect of the slide rail, the two translation plates 22 can be moved relative to each other until the two limiting plates 18 pass through the interior of the two limiting slots 23 and the two translation plates 22 abut against the front and rear sides of the positioning frame 7 respectively. At this time, since the two limiting plates 18 are adapted to the two limiting slots 23 respectively, the movement of the solar cell module 2 and the frame 3 can be prevented, thus completing the installation of the solar cell module 2.

[0031] When it is necessary to remove the solar cell module 2 from the positioning frame 7, rotate the two screws 21 in the opposite direction to make the two translation plates 22 move in opposite directions and make the two limiting plates 18 and the two guide cones 25 disengage from the two limiting grooves 23. Thus, the solar cell module 2 and the frame 3 can be easily removed from the positioning frame 7. Combined with the above installation steps for the solar cell module 2, the purpose of facilitating the disassembly, replacement or maintenance of the solar cell module 2 can be achieved.

[0032] After the solar panel 2 is installed, the drive mechanism moves the moving platform 8 to the right. Since the connecting rod 10 is movably connected to the moving platform 8 and the connecting plate 9 via hinges, and the L-shaped rod 6 is movably connected to the upper side of the support platform 5 via a hinge, the positioning frame 7 can be pushed to rotate clockwise around the axis of the hinge on the support platform 5, simultaneously causing the solar panel 2 to rotate clockwise. At this time, the tilt angle of the solar panel 2 will increase. Conversely, when the moving platform 8 moves to the left, the tilt angle of the solar panel 2 will decrease, thus adjusting the angle of the solar panel 2. When the angle of sunlight is in the opposite direction, the internal threaded cylinder 13 is rotated. Since the threaded post 12 is threadedly connected to the inner wall of the internal threaded cylinder 13, the internal threaded cylinder 13 and the limiting post 15 can move downwards until the limiting post 15 disengages from the limiting hole 14, thereby releasing the restriction on the steering plate 4. Then, the steering plate 4 is rotated... When the steering plate 4 is rotated 180 degrees, it will rotate along with the steering column 11, simultaneously causing the positioning frame 7 and the solar cell module 2 to rotate 180 degrees. This allows the left-side limiting hole 14 to be rotated to the right-side position. Then, the internal threaded cylinder 13 is rotated in the opposite direction, causing the internal threaded cylinder 13 and the limiting column 15 to move upwards until the limiting column 15 enters the interior of the right-side limiting hole 14, and the internal threaded cylinder 13 abuts against the lower end of the steering plate 4. Since the limiting column 15 and the limiting hole 14 are matched, the steering plate 4 is prevented from rotating. At this time, the tilted surface of the solar cell module 2 faces the opposite side. The tilt angle of the solar cell module 2 can be adjusted in the same way as above to adapt to the sunlight. In this way, the range of angle adjustment of the solar cell module 2 is increased, thereby improving the flexibility of use and making it fully adaptable to changes in the angle of sunlight.

[0033] As a technical optimization of this utility model, the drive mechanism includes two vertical plates 24 fixedly connected to the upper end of the steering plate 4. A lead screw 29 is rotatably connected between the two vertical plates 24, passing through the moving platform 8 and threadedly connected thereto. A drive frame 26 is installed at the left end of the left vertical plate 24. A worm gear 27 is rotatably connected inside the drive frame 26. A worm wheel 28 is meshed with the outer wall of the worm gear 27. A transmission shaft passing through the left vertical plate 24 is fixedly connected between the worm wheel 28 and the lead screw 29. A handwheel extending to the outside of the drive frame 26 is installed at the upper end of the worm gear 27.

[0034] In this embodiment: the worm 27 is rotated by the handwheel, which in turn drives the worm wheel 28 to rotate, thereby driving the lead screw 29 to rotate through the transmission shaft. After the tilt angle adjustment is completed, the worm 27 and the worm wheel 28 have a self-locking characteristic, which prevents the lead screw 29 from rotating, and further prevents the angle of the solar cell module 2 from changing.

[0035] As a technical optimization of this utility model, a rectangular frame 16 that fits against the lower end of the frame 3 is installed inside the positioning frame 7.

[0036] In this embodiment: a rectangular frame 16 is set to support the border 3.

[0037] As a technical optimization of this utility model, guide cones 25 are provided on the opposite sides of the two limiting plates 18.

[0038] In this embodiment, by setting two guide cones 25, it is convenient for the two limiting plates 18 to enter the interior of the two limiting grooves 23.

[0039] As a technical optimization of this utility model, the two screws 21 are rotatably connected to the front and rear sides of the positioning frame 7 on opposite sides.

[0040] In this embodiment, since the two screws 21 are rotatably connected to the front and rear sides of the positioning frame 7 on opposite sides, the stability of the installation of the two screws 21 can be improved.

[0041] As a technical optimization of this utility model, an annular groove is provided at the upper end of the base 1, and an annular slider that is fixedly connected to the lower end of the steering column 11 is slidably connected inside the annular groove.

[0042] In this embodiment, an annular groove and an annular slider are provided to improve the stability of the steering column 11 rotation.

[0043] As a technical optimization of this utility model, the outer wall of the internally threaded cylinder 13 is equipped with multiple connecting rods, and the other end of the multiple connecting rods is fixedly connected to a hand-rotating ring.

[0044] In this embodiment: multiple connecting rods are provided to fix the hand-operated ring, and the hand-operated ring is provided to rotate the internal threaded cylinder 13.

[0045] The working principle and usage process of this utility model are as follows: When installing the solar cell module 2, the solar cell module 2, together with the frame 3, is inserted into the interior of the positioning frame 7 until the frame 3 contacts the rectangular frame 16. Since the outer wall of the frame 3 fits against the inner wall of the positioning frame 7, the installation position of the solar cell module 2 can be positioned. At the same time, the two limiting plates 18 will enter the interior of the two slots 17. Then, the two screws 21 are rotated by the two handwheels respectively. Due to the limiting effect of the slide rail, the two translation plates 22 can be moved relative to each other until the two limiting plates 18 pass through the interior of the two limiting slots 23 and the two translation plates 22 abut against the front and rear sides of the positioning frame 7 respectively. At this time, since the two limiting plates 18 are respectively adapted to the two limiting slots 23, the movement of the solar cell module 2 and the frame 3 can be prevented, thus completing the installation of the solar cell module 2.

[0046] When it is necessary to remove the solar cell module 2 from the positioning frame 7, rotate the two screws 21 in the opposite direction to make the two translation plates 22 move in opposite directions and make the two limiting plates 18 and the two guide cones 25 disengage from the two limiting grooves 23. Thus, the solar cell module 2 and the frame 3 can be easily removed from the positioning frame 7. Combined with the above installation steps for the solar cell module 2, the purpose of facilitating the disassembly, replacement or maintenance of the solar cell module 2 can be achieved.

[0047] After the solar cell module 2 is installed, the worm gear 27 is rotated by handwheel, which in turn drives the worm wheel 28 to rotate. This, in turn, drives the lead screw 29 to rotate via the transmission shaft, thus moving the moving platform 8 to the right. Since the connecting rod 10 is movably connected to the moving platform 8 and the connecting plate 9 via hinges, and the L-shaped rod 6 is movably connected to the upper side of the support platform 5 via a hinge, the positioning frame 7 can be pushed to rotate clockwise around the axis of the hinge on the support platform 5, simultaneously causing the solar cell module 2 to rotate clockwise. At this time, the tilt angle of the solar cell module 2 will increase. Conversely, when the moving platform 8 moves to the left, the tilt angle of the solar cell module 2 will decrease, thus adjusting the angle of the solar cell module 2. When the angle of sunlight is in the opposite direction, the internal threaded cylinder 13 is rotated. Since the threaded post 12 is threadedly connected to the inner wall of the internal threaded cylinder 13, the internal threaded cylinder 13 and the limiting post 15 can be moved downwards until the limiting post 15 disengages from the interior of the limiting hole 14, thereby releasing the solar cell module 2. In addition to restricting the steering plate 4, rotating the steering plate 4 by 180 degrees will cause the steering plate 4 to rotate along with the steering column 11, simultaneously rotating the positioning frame 7 and the solar cell module 2 by 180 degrees. This will allow the left-side limiting hole 14 to be rotated to the right-side position. Then, rotating the internal threaded cylinder 13 in the opposite direction will cause the internal threaded cylinder 13 and the limiting column 15 to move upwards until the limiting column 15 enters the interior of the right-side limiting hole 14, and the internal threaded cylinder 13 abuts against the lower end of the steering plate 4. Since the limiting column 15 and the limiting hole 14 are matched, the steering plate 4 can be prevented from rotating. At this time, the tilted surface of the solar cell module 2 faces the opposite side. The tilt angle of the solar cell module 2 can be adjusted in the same way as above to adapt to the sunlight. In this way, the range of angle adjustment of the solar cell module 2 can be increased to improve the flexibility of use and make it fully adaptable to changes in the angle of sunlight.
