Description

Technical Field

[0001] This utility model belongs to the field of floating photovoltaic technology, and specifically refers to a rapid maintenance structure for the floating body of a floating photovoltaic power generation system. Background Technology

[0002] Floating photovoltaic power generation systems rely on floats to provide buoyancy and float on water, with the floats connected by plastic bolts to form an array. Due to prolonged immersion in water and exposure to wind and sun, the floats inevitably suffer damage and leakage due to aging, collisions, and other reasons, leading to a decrease in local buoyancy and affecting the stability of adjacent floats, and may even cause the collapse of maintenance channels.

[0003] The existing floats are connected by overlapping connecting lugs and secured with bolts and nuts. Based on this structure, existing repair methods require disassembling the surrounding floats to replace the damaged float, which is time-consuming, costly, and affects power generation efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a quick maintenance structure for the floating body of a floating photovoltaic power generation system, which solves the problems existing in the prior art and can quickly complete operation and maintenance without disassembling the floating body, thus improving the convenience of operation and maintenance.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A quick-maintenance structure for a floating photovoltaic power generation system includes a float, a cover plate, a nut, a locking ring, and bolts. The cover plate fits onto the upper surface of the float, and the ends of the float and the cover plate are respectively provided with a first connecting lug and a second connecting lug. The first connecting lugs of adjacent floats overlap each other, and the second connecting lugs of the cover plates above adjacent floats overlap each other. The nut is disposed between the first connecting lug and the second connecting lug, and the locking ring is disposed above the second connecting lug. The bolt passes through the first connecting lug, the nut, the second connecting lug, and the locking ring sequentially from bottom to top, and is threadedly connected to the nut and the locking ring respectively. The inner wall of the locking ring is provided with a plurality of spring pieces that are tightly fitted into the threads of the bolt.

[0007] The spring pieces are arranged at equal angular intervals on the inner wall of the locking ring.

[0008] The first connecting lugs at both ends of the float have a height difference, and the second connecting lugs at both ends of the cover plate have a height difference.

[0009] The cover plate has an inclined enclosure on its side, which covers the side of the upper surface of the float.

[0010] The upper surface of the cover plate is provided with several anti-slip patterns.

[0011] The locking ring has several anti-slip vertical grooves on its circumference.

[0012] The lower outer wall of the nut protrudes to form a support ring, and several reinforcing ribs connect the support ring to the outer wall of the nut.

[0013] The nut has a plurality of anti-slip buckles spaced at equal angles on the upper inner wall, and the bolt has anti-slip buckles on its circumferential surface. The anti-slip buckles of the nut and the anti-slip buckles of the bolt are slidably engaged to prevent the nut from being turned in the opening direction.

[0014] The lower end of the bolt is provided with a plurality of anti-rotation protrusions, and the inner wall of the through hole of the first connecting ear is provided with an anti-rotation groove for the anti-rotation protrusions to be embedded.

[0015] After adopting the above technical solution, the present invention has the following technical effects:

[0016] (1) This utility model realizes structural reuse, directly using the bolts originally used to connect the floats as the mechanical anchor points of the cover plate, reducing the modification cost, and forming a closed force transmission path through the bolts-cover plate-adjacent floats, making the cover plate an organic component of the float array rather than an independent additional structure.

[0017] (2) This utility model uses a cover plate to cover and protect the upper surface of the float, and serves as the surface of the operation and maintenance passage for workers to step on. The float is not easily damaged because it is protected.

[0018] (3) In the process of disassembly and assembly, the cover plate can be quickly replaced by simply removing and installing the locking ring, without disassembling and assembling the float. This avoids secondary damage to the original float and bolt connection structure caused by disassembly and assembly of the float. The first connecting lug between the floats is still locked by the nut, which can also ensure that the structural stability of the float array is not damaged. During the disassembly and assembly process, the worker has a stable stress point, which is safer. Moreover, the entire process of replacing the cover plate can be operated by a single person, realizing rapid maintenance and improving operation and maintenance efficiency.

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] refer to Figure 1-5 As shown, this utility model discloses a quick maintenance structure for the floating body of a waterborne photovoltaic power generation system, including a floating body 1, a cover plate 2, a nut 3, a locking ring 4, and a bolt 5;

[0032] The cover plate 2 is fitted onto the upper surface of the float 1, and the ends of the float 1 and the cover plate 2 are respectively provided with a first connecting lug 11 and a second connecting lug 21;

[0033] The first connecting lugs 11 of adjacent floats 1 overlap each other, and the second connecting lugs 21 of the cover plates 2 above adjacent floats 1 overlap each other;

[0034] Nut 3 is positioned between the first connecting lug 11 and the second connecting lug 21, and locking ring 4 is positioned above the second connecting lug 21. Nut 3 and locking ring 4 are both coaxially positioned with the through holes of the first connecting lug 11 / second connecting lug 21.

[0035] Bolt 5 passes through the first connecting lug 11, nut 3, second connecting lug 21 and locking ring 4 from bottom to top, and is threadedly connected to nut 3 and locking ring 4 respectively. The inner wall of locking ring 4 is provided with a number of spring pieces 41 that are tightly fitted into the threads of bolt 5.

[0036] Through the above solution, this utility model achieves structural reuse, directly using the bolts 5 originally used to connect the floats 1 as the mechanical anchoring points of the cover plate 2, reducing modification costs. Furthermore, a closed force transmission path is formed through bolts 5, cover plate 2, and adjacent floats 1, making the cover plate 2 an organic component of the float array, rather than an independent additional structure. This utility model uses the cover plate 2 to cover and protect the upper surface of the floats 1, and also serves as a surface for workers to walk on during maintenance. The floats 1 are less prone to damage due to this protection. During disassembly and assembly, the cover plate 2 can be quickly replaced simply by removing and installing the locking ring 4, without disassembling the floats 1. This avoids secondary damage to the original floats and bolt connection structure caused by disassembling and installing the floats 1. The first connecting lugs 11 between the floats 1 are still locked by nuts 3, ensuring the structural stability of the float array is not compromised. Workers have stable stress points during disassembly and assembly, resulting in higher safety. The entire process of replacing the cover plate 2 can be operated by a single person, enabling rapid maintenance and improving operational efficiency.

[0037] The following are specific embodiments of the present invention.

[0038] The aforementioned spring pieces 41 are arranged at equal angular intervals on the inner wall of the locking ring 4.

[0039] The first connecting lugs 11 at both ends of the aforementioned float 1 have a height difference, that is, the lower surface of one first connecting lug 11 of the same float 1 is higher than the upper surface of the other connecting lug 11, so that the first connecting lugs 11 between adjacent floats 1 can be fitted together without interference, thereby maintaining a consistent upper surface height; similarly, the second connecting lugs 21 at both ends of the cover plate 2 also have a height difference. In this way, it is also convenient to stack and transport the cover plates 2, and multiple cover plates 2 can be locked together using bolts.

[0040] The cover plate 2 has an inclined surrounding plate 22 on its side, which covers the side of the upper surface of the float 1. Thus, the surrounding plate 22 can be connected end to end to form a circle, and together with the cover plate 2, form a groove 23. This groove 23 can accommodate the upper surface of another cover plate or the upper surface of the float 1, facilitating the stacking of multiple cover plates 2 for easy transportation and space saving, while also ensuring a stable fit between the cover plate 2 and the float 1, preventing displacement. The side of the upper surface of the float 1 can be provided with an inclined surface or an arc surface opposite to the surrounding plate 22.

[0041] Furthermore, the sidewall of the aforementioned nested guide groove 22 is provided with a guide slope 23.

[0042] The upper surface of the cover plate 2 is provided with several anti-slip patterns (not shown in the figure) to enhance friction and achieve anti-slip.

[0043] The locking ring 4 has several anti-slip vertical grooves 42 on its circumference to enhance friction and facilitate one-handed turning of the locking ring 4.

[0044] The lower outer wall of the nut 3 has a protruding support ring 31, and several reinforcing ribs 32 are connected between the support ring 31 and the outer wall of the nut 3. This can improve the strength of the nut 3.

[0045] The upper inner wall of the nut 3 is provided with several anti-slip buckles 33 at equal angles, and the circumferential surface of the bolt 5 is provided with anti-slip buckles 51. The anti-slip buckles 33 and the anti-slip buckles 51 are slidably engaged to prevent the nut 3 from being turned in the opening direction.

[0046] The lower outer wall of the bolt 5 is provided with a number of anti-rotation protrusions 52, and the inner wall of the through hole of the first connecting ear 11 is provided with an anti-rotation groove 12 for the anti-rotation protrusions 52 to be embedded, so as to prevent the bolt 5 from rotating relative to the first connecting ear 11 and improve the structural stability.

[0047] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
