Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel fixing in offshore photovoltaic project construction, and in particular to an adjustable photovoltaic panel fixing buckle. Background Art

[0002] During the construction of offshore photovoltaic projects, there are two ways to use fixing clips to fix photovoltaic panels:

[0003] The first method is to place all photovoltaic panels for hoisting and installation on the sea surface and use fixing clips to fix the photovoltaic panels. This operation requires workers to climb to the top of the photovoltaic panels for a long time to carry out construction work, which poses great safety risks.

[0004] The second method is to fix most of the photovoltaic panels with fixing clips on the assembly site, and fix the remaining photovoltaic panels with fixing clips on the sea surface. This operation requires workers to climb to the top of the photovoltaic panels to carry out construction work, and the safety risks are still very high.

[0005] The above two methods cannot effectively guarantee the safety of workers fixing photovoltaic panels on the sea surface, and the construction efficiency of fixing the buckles on the top of photovoltaic panels on the sea surface is low. The photovoltaic panel fixing buckles circulating on the market cannot be folded, which poses a great safety risk to workers fixing photovoltaic panels at sea.

[0006] How to solve the above problems is the research topic of this program. Utility Model Content

[0007] In order to achieve the above-mentioned purpose of the utility model and to address the above-mentioned technical problems, the utility model provides an adjustable photovoltaic panel fixing buckle.

[0008] The technical solution is as follows: it comprises a nut, a buckle body, a rotating shaft and a screw rod arranged on the buckle body and used for unidirectional rotation;

[0009] The nut comprises two parts, an upper part and a lower part, respectively, and the upper part and the lower part are arranged coaxially with the screw;

[0010] The buckle body comprises a bottom plate and two side plates symmetrically arranged on the bottom plate, and a pressure plate is arranged on the top of the outer wall of the side plate;

[0011] The rotating shaft is arranged on the side plate on either side;

[0012] The screw rod is fixedly arranged at the bottom of the lower part of the nut.

[0013] The overall length of the nut is 25 mm, of which the upper part is 13 mm long and 17.5 mm in diameter, and the lower part is 12 mm long and 8 mm in diameter. Both the upper and lower parts are made of stainless steel.

[0014] The side panel is 25mm high, the bottom panel is 4.5mm thick, and 6mm from the bottom of the side panel on either side, a rotating shaft with a length of 20mm and a diameter of 5mm is set. The upper part of the side panel with the rotating shaft is rotatably connected to the lower part of the side panel through the rotating shaft. The original fixed buckle structure is innovated, and a single-sided rotating shaft is added for one-way rotation. The upper and lower side panels at the rotating shaft are disconnected and connected by the rotating shaft, which is the same as the rotating shaft of a conventional wooden door that rotates to open. The stainless steel plate connecting the upper and lower parts of the rotating shaft is customized by the manufacturer to ensure that the upper and lower sides can be vertically and tightly combined, and to ensure that there is no additional thickness affecting the docking accuracy;

[0015] The screw has a diameter of 8 mm and a length of 165 mm, and extends downward from the bottom of the buckle body.

[0016] A through hole is provided on the bottom plate, and the screw rod is slidably connected with the through hole.

[0017] The bottom of the pressing plate is provided with a plurality of evenly distributed grooves, and the distance from one end to the other end of the pressing plate is 38 mm.

[0018] The nut is located between two side plates of the buckle body.

[0019] The upper and lower parts of the nut are both configured as hexagonal prism structures, and the side length of the upper part is greater than the side length of the lower part;

[0020] The bottom of each edge of the upper part is provided with an inclined groove.

[0021] The original nut is innovated to produce a variable diameter circular nut. The upper and lower parts of the nut are designed to be coaxial with the screw to provide structural stability. The upper and lower parts are made of stainless steel to increase corrosion resistance and durability. The hexagonal prism structure of the upper part and the inclined groove design at the bottom of the edge provide better operation convenience.

[0022] The design of the bottom plate and side plates provides sufficient strength and stability to withstand the weight of the photovoltaic panels and the wind on the sea. The pressure plate design on the side plates helps to better fix the photovoltaic panels and increase friction through grooves to prevent the photovoltaic panels from sliding.

[0023] The setting of the rotating shaft allows the side panel to rotate in one direction, which makes the buckle adapt to the needs of fixing photovoltaic panels at different angles, improving the flexibility and efficiency of installation.

[0024] The length and diameter of the screw allow it to penetrate deep into the clip body, providing a stable fixing force. The sliding connection with the through hole on the base plate allows the screw to be fine-tuned during installation to accommodate photovoltaic panels of different thicknesses.

[0025] The groove design at the bottom of the pressure plate helps to increase the friction when in contact with the photovoltaic panel, ensuring the stability of the photovoltaic panel on the sea surface. The length design of the pressure plate allows it to cover a larger area of ​​the photovoltaic panel, providing a better fixing effect.

[0026] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are as follows: the solution provides an adjustable photovoltaic panel fixing buckle, which, through the innovative buckle design, can rotate the single-side stainless steel plate to meet the straight up and down requirements during the photovoltaic panel fixing process, and can achieve secondary support fixation after rotation, thereby reducing the operation time and energy for fixing the offshore photovoltaic panel, and can greatly reduce the safety risks of operators using fixing buckles to fix photovoltaic panels at sea, thereby ensuring the personal safety of operators at sea, and can solve the problem that operators need to climb to the top of the photovoltaic panel to work. Operators no longer need to climb to the top of the photovoltaic panel to fix the photovoltaic panel, and at the same time, the fixing construction efficiency can be greatly improved during the photovoltaic panel fixing operation on the sea surface, thereby achieving a dual improvement in the safety and efficiency of the offshore photovoltaic panel fixing operation, and the safety of operators is guaranteed. At the same time, the construction time is shortened, the construction cost is reduced, and the overall economic benefits are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figures 1 to 3 The utility model provides an adjustable photovoltaic panel fixing buckle, comprising a nut 1, a buckle body 5, a rotating shaft 2 and a screw rod 3 arranged on the buckle body 5 for unidirectional rotation;

[0037] The nut 1 includes two parts, an upper part 101 and a lower part 102, respectively. The upper part 101 and the lower part 102 are coaxially arranged with the screw rod 3;

[0038] The buckle body 5 includes a bottom plate 501 and two side plates 502 symmetrically arranged on the bottom plate 501, and a pressure plate 503 is arranged on the top of the outer wall of the side plate 502;

[0039] The rotating shaft 2 is arranged on the side plate 502 on either side;

[0040] The screw rod 3 is fixedly disposed at the bottom of the lower portion 102 of the nut 1 .

[0041] The nut 1 has an overall length of 25 mm, of which the upper portion 101 has a length of 13 mm and a diameter of 17.5 mm, and the lower portion 102 has a length of 12 mm and a diameter of 8 mm. Both the upper portion 101 and the lower portion 102 are made of stainless steel.

[0042] The side panel 502 is 25 mm high, the bottom panel 501 is 4.5 mm thick, and a shaft 2 with a length of 20 mm and a diameter of 5 mm is provided 6 mm from the bottom of the side panel 502 on either side. The upper portion of the side panel 502 provided with the shaft 2 is rotatably connected to the lower portion of the side panel 502 via the shaft 2.

[0043] The screw 3 has a diameter of 8 mm and a length of 165 mm, and extends downward from the bottom of the buckle body 5 .

[0044] A through hole is provided on the bottom plate 501, and the screw rod 3 is slidably connected to the through hole.

[0045] A plurality of evenly distributed grooves 504 are provided at the bottom of the pressing plate 503, and the distance from one end to the other end of the pressing plate 503 is 38 mm.

[0046] The nut 1 is located between the two side plates 502 of the buckle body 5 .

[0047] The upper part 101 and the lower part 102 of the nut 1 are both configured as hexagonal prism structures, and the side length of the upper part 101 is greater than the side length of the lower part 102;

[0048] Each edge bottom of the upper portion 101 is provided with an inclined groove 1011 .

[0049] When the utility model is used, the following steps are included:

[0050] (1) All photovoltaic panels on the ground are fixed with fixing buckles, and the positions of 8 photovoltaic panels required for offshore lifting are reserved. The photovoltaic panels on both sides of the reserved positions are fixed with the adjustable photovoltaic panel fixing buckles designed in this scheme, and the adjustable part is reserved for the rear fixing. The photovoltaic panels fixed on the ground cannot be adjusted;

[0051] (2) The whole steel truss photovoltaic panel is hoisted and installed on the sea surface and the welding is completed. The photovoltaic panels need to be supplemented at the positions of the 8 photovoltaic panel hoisting points previously reserved. The photovoltaic panel is placed above the reserved position by slowly descending from the air using a hoisting tool. The screw 3 is lifted up by hand so that the nut 1 is placed above the adjustable fixing buckle. The upper part of the single-sided stainless steel plate, i.e., the side plate 502 provided with the rotating shaft 2, is adjusted and rotated to realize the original side plate position to rotate obliquely upwards, and the original side plate position is vacated.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
