Description

Technical Field

[0001] This invention relates to photovoltaic technology, and more particularly to a floating photovoltaic cell module. Background Technology

[0002] Floating photovoltaic (PV) platforms are an essential structure for building floating PV power plants. Currently, most of the floating bodies of these platforms are partially above the water surface. Furthermore, the PV mounting brackets used to install the PV modules on these floating platforms largely adopt the same structure as those used for land-based installations. Those skilled in the art will understand the difference between water-based and land-based installations. Water-based installations are subject to swaying, making it difficult to handle the components. Even slight mishaps can cause parts to fall into the water, significantly reducing operational efficiency.

[0003] CN207720056U discloses a floating photovoltaic power station system. This system employs a connection structure to install photovoltaic modules. Specifically, during the assembly of the photovoltaic modules onto the connecting inclined beam, hooks are attached to the first extension of the purlin. The photovoltaic modules automatically hook onto the purlin using their own weight. Then, workers use bolts and lock nuts to connect to the connecting through holes and mating through holes, thereby fixing the photovoltaic modules onto the purlin. Finally, screws are used to fix the second extension of the purlin to the connecting inclined beam. This system requires numerous steps and is relatively cumbersome to install, presenting certain limitations compared to surface-mounted installations and reducing installation efficiency.

[0004] In addition, after installation, it is difficult to control the balance between different directions. Since the photovoltaic modules are installed at an angle, the center of gravity of the photovoltaic modules will shift, which will cause the entire floating cylinder to tilt, causing safety issues to the entire power station system. Maintaining a tilted state for a long time will cause uneven stress on the photovoltaic modules and make the components prone to damage. Summary of the Invention

[0025] In this invention, the mounting component is provided with four symmetrically arranged limiting holes, and the actuator is provided with limiting protrusions that cooperate with the limiting holes.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] like Figures 1 to 13 As shown, this floating photovoltaic module of the present invention includes a floating base 1, a mounting column 2, a fixing component 3, an adjusting component 4, and a photovoltaic panel 5. The floating base 1 has a hollowed-out center forming a hollow chamber 6, through which it can float on the water surface. The floating base 1 has four diagonally arranged mounting slots 7, in which the adjusting component 4 is disposed. After being disposed in the mounting slots 7, the adjusting component 4 can adjust the balance of the floating base 1, ensuring that all four sides of the floating base 1 are at the same waterline, thus maintaining the balance of the entire floating base 1.

[0043] Mounting column 2 is mounted on floating base 1, and mounting block 8 is provided on mounting column 2 perpendicular to mounting column 2. Fixing components 3 are provided at both ends of mounting block 8, and can be used to install photovoltaic panel 5 onto mounting block 8.

[0044] Mounting column 2 is set perpendicular to floating base 1, but photovoltaic panel 5 needs to face the sun during installation, requiring a certain tilt angle. Therefore, when mounting block 8 is installed on mounting column 2, it is also kept parallel to photovoltaic panel 5 to ensure that photovoltaic panel 5 and mounting block 8 remain relatively horizontal, making installation more stable. Thus, mounting block 8 will also have a certain angle when installed on mounting column 2.

[0045] The fixing component 3 not only maintains the vertical position of the photovoltaic panel 5 and the mounting block 8, but also limits the horizontal position of the photovoltaic panel 5 on the mounting block 8. Positioning posts 9 are provided on the photovoltaic panel 5, and positioning holes 10 that mate with the positioning posts 9 are provided on the mounting block 8. The cooperation between the positioning posts 9 and the positioning holes 10 allows for the limitation of the horizontal position of the photovoltaic panel 5 on the mounting block 8. This also facilitates the positioning and installation of the fixing component 3 and the photovoltaic panel 5, enabling rapid assembly of the photovoltaic panel 5.

[0046] Because the photovoltaic panel 5 requires a certain tilt angle during installation to maximize its ability to receive sunlight, its center of gravity is tilted to one end after it is installed on the floating base 1. To ensure the floating base 1 remains balanced, four diagonally positioned adjustment components 4 are provided on it. Rotating these components ensures the floating base 1 is balanced, allowing the photovoltaic panel 5 to be positioned within the correct tilt angle range for better sunlight reception.

[0047] The adjustment assembly 4 has a drive rod 11 and a locking member 12. The locking member 12 has a first threaded hole 13 in the middle. The drive rod 11 has a first threaded part 14 that mates with the first threaded hole 13. Rotating the drive rod 11 can keep the locking member 12 moving along the direction of the first threaded part 14 on the drive rod 11.

[0048] The lower end of the locking member 12 is provided with a fixing part 15, the upper end of the locking member 12 is provided with a second threaded part 16, the locking member 12 is provided with a locking member 17 that cooperates with the second threaded part 16, and the middle of the locking member 17 is provided with a second threaded hole 18 that cooperates with the second threaded part 16.

[0049] The distance between any opposing surfaces on the fixing part 15 and the locking member 17 is greater than the width of the mounting groove 7. This ensures that the fixing part 15 and the locking member 17 can be positioned at the upper and lower ends of the mounting groove 7. After rotating the locking member 17, the locking member 12 can be fixed in the designated position.

[0050] One end of the drive rod 11 is provided with a gear part 19, and the mounting groove 7 also has a recessed groove 20 that mates with the gear part 19. The recessed groove 20 facilitates the insertion of the rack into it, so that the rack mates with the gear part 19. When the rack is pushed or pulled, the gear part 19 can be driven to rotate, thereby realizing the rotation of the drive rod 11. The first threaded part 14 on the drive rod 11 mates with the first threaded hole 13 on the locking member 12, so that the locking member 12 moves on the drive rod 11.

[0051] In use, simply rotate the locking member 17 to create a gap between the lower end face of the locking member 17 and the upper end face of the floating base 1, ensuring the locking member 12 can move. Because the gap between the locking member 17 and the floating base 1 is small, when the drive rod 11 rotates, the locking member 12 is restricted by the fixing part 15 and the position of the locking member 17 against the floating base 1, keeping it in a nearly vertical state and preventing it from rotating with the drive rod 11. Therefore, the locking member 12 can move on the drive rod 11 through the engagement of the first threaded part 14 and the first threaded hole 13. Tightening the locking member 17 then secures it, and the clamping force between the locking member 17 and the fixing part 15 ensures the locking member 12 will not move.

[0052] After one of the locking components 12 moves to a position on the drive rod 11, the state of the floating base 1 can be observed, and the other three adjustment components 4 can be adjusted to make the floating base 1 in a balanced state.

[0053] In the adjustment assembly 4, the locking element 12 acts as a counterweight, which adjusts the weight of each corner to control the balance of the floating base 1.

[0054] The fixing component 3 includes a limiting member 21, a pressure applying member 22, a limiting rod 23, a contact member 24, a first spring 25, a mounting member 26, an actuating member 27, a second spring 28, and a limiting nut 29.

[0055] Limiting rods 23 are located at both ends of the mounting block 8, and the upper end of the limiting rods 23 is provided with a limiting end 31 that cooperates with the limiting arm 30. The limiting rods 23 are composed of the limiting end 31, the mounting rod 32, the rotating disk 33, and the third threaded part 34 from top to bottom. The rotating disk 33 is located between the mounting rod 32 and the third threaded part 34.

[0056] The limiting end 31 has a spherical surface 35 and first cut surfaces 36 on both sides of the spherical surface 35. The limiting end 31 is hemispherical, and after being cut at both ends, symmetrical first cut surfaces 36 are formed. The limiting end 31 can be detached from the mounting rod 32 and fixed to the mounting rod 32 with bolts. A limiting structure can be added to the limiting end 31 to ensure that the limiting end 31 rotates along with the mounting rod 32 when it rotates.

[0057] The limiting member 21 is installed on the bottom surface of the photovoltaic panel 5, and the limiting member 21 extends symmetrically arranged limiting arms 30 from both ends. The limiting arm 30 has a holding part 37 and a guiding part 38, and there is an included angle between the holding part 37 and the guiding part 38. This makes the guiding part 38 in an inclined state, which can cooperate with the limiting end 31, so that the guiding part 38 and the holding part 37 are deformed under force.

[0058] A limiting region 39 is provided between the symmetrical guide portions 38 for placing the limiting end 31, and the distance of the limiting region 39 is less than the maximum diameter of the limiting end 31.

[0059] The pressure-applying member 22 is installed at the lower end of the limiting arm 30 and the lower end of the retaining part 37. The pressure-applying member 22 has a V-shaped portion 40, which contacts the lower end face of the retaining part 37. The pressure-applying member 22 consists of a connecting section 41, a downward tilting section 42, a transition section 43, a bridging section 44, and an abutting section 45, wherein the V-shaped portion 40 is formed between the bridging section 44 and the abutting section 45. The connecting section 41 is located at the lower end of the retaining part 37, and the pressure-applying member 22 can be welded to the lower end of the retaining part 37. The connection between the bridging section 44 and the abutting section 45 forms a pressure-applying section 46, which is used to apply pressure to the contact member 24.

[0060] The upper end of the contacting section 45 contacts the connection between the retaining part 37 and the guide part 38. For example... Figure 13 As shown, when the limiting member 21 descends along the direction of F1 with the pressure applying member 22, the pressure applying section 46 first contacts the contact member 24 and applies pressure to it. The contact member 24 then applies a reverse force to the abutting section 45, which is applied to the retaining part 37, causing the retaining part 37 to deform upwards. As it continues to move downwards, the guide part 38 contacts the spherical surface 35, which applies a reverse force to the guide part 38, causing it to deform. The guide part 21 then passes over the spherical surface 35 and reaches the lower end face a of the limiting end 31, thus fixing the limiting member 21 to the lower end of the limiting end 31.

[0061] There is a gap between the transition section 43 and the holding part 37, forming an active area 47. When the pressure member 22 moves downward, it is subjected to the reverse force of the contact member 24. The bridging section 44 presses on the transition section 43, thereby compressing the active area 47 and buffering the pressure member 22, thus buffering the photovoltaic panel 5 and protecting the photovoltaic panel 5.

[0062] The contact element 24 and the first spring 25 are mounted on the mounting rod 32 on the limiting rod 23. One end of the first spring 25 contacts the contact element 24, and the other end contacts the mounting block 8. The upper end of the contact element 24 contacts the pressure application element 22. The mounting block 8 is located between the rotating disk 33 and the first spring 25.

[0063] Mounting component 26 is used to mount the limiting rod 23 onto the mounting block 8, located at the lower end of the rotating disk 33. The mounting component 26 has symmetrically arranged planar bearings 48 in the middle, and the limiting rod 23 has a rotating disk 33 on which the symmetrical planar bearings 48 are mounted, facilitating the rotation of the limiting rod 23 via the planar bearings 48.

[0064] The third threaded portion 34 has a second cut surface 49, and is equipped with an actuator 27, a second spring 28, and a limiting nut 29. The actuator 27 has an actuator hole 50 in the middle that mates with the third threaded portion 34. One end of the second spring 28 contacts the actuator 27, and the other end contacts the limiting nut 29. The cross-section of the actuator hole 50 mates with the cross-section of the third threaded portion 34. When the actuator 27 rotates, it can drive the limiting rod 23 to rotate.

[0065] The actuator 27 has a receiving hole 51 in the middle to accommodate the second spring 28. The mounting member 26 has a placement chamber 52 in the middle to accommodate the plane bearing 48 and the rotating disk 33, and also has a through hole 53 through which the limiting rod 23 passes, as well as a fixing end 54 for fixing the mounting member 26. A gasket 55 is provided between the fixing end 54 and the mounting block 8 to facilitate the installation of the mounting member 26.

[0066] Rotating the limiting nut 29 adjusts the spring force of the second spring 28, maintaining a defined distance between the actuator 27 and the mounting member 26. The mounting member 26 is fixed to the mounting block 8 and will not move.

[0067] The mounting component 26 has four symmetrically arranged limiting holes 56, and the actuator 27 has limiting protrusions 57 that cooperate with the limiting holes 56. The four limiting holes 56 are arranged at 90° intervals between each other, while the limiting protrusions 57 are arranged at 180° intervals. The actuator 27 has a handle 58. By pulling the handle 58, the second spring 28 can be compressed, causing the limiting protrusions 57 to disengage from two of the limiting holes 56. After rotating 90°, the limiting rod 23 rotates with the component, ensuring that the guide part 38 is disengaged from the limiting end 31. The pressure component 22 and the limiting component 21 disengage from the limiting area 39 under the push of the first spring 25, and the guide part 38 moves upward at the cross-section. Then, the limiting protrusions 57 are placed in the other two limiting holes 56 to limit the position of the limiting rod 23, allowing the photovoltaic panel 5 to be removed from the fixing component 3.

[0068] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
