[0030] This disclosure provides a tooling for offshore photovoltaic systems that includes an externally serrated burr pad, such as... Figure 1 As shown, the tooling may include a first nut 1, a second nut 6, a first washer 2, a second washer 5, a first burr washer 3, a second burr washer 4, and a screw 7, wherein:

[0031] The first nut 1 and the second nut 6 are parallel and directly opposite each other;

[0032] The first washer 2 is located between the first nut 1 and the second nut 6;

[0033] The second washer 5 is located between the first washer 2 and the second nut 6;

[0034] The first burr gasket 3 is located between the first gasket 2 and the second gasket 5;

[0035] The second burr pad 4 is located between the first burr pad 3 and the second pad 5;

[0037] The tool for offshore photovoltaic containing outer sawtooth burr gasket of the present disclosure can be used to arrange the first nut 1, the first gasket 2 and the first burr gasket 3 on one side of the grounding area of the photovoltaic net rack, to arrange the second nut 6, the second gasket 5 and the second burr gasket 4 on the other side of the grounding area of the photovoltaic net rack, to make the screw rod 7 pass through the first nut 1, the first gasket 2, the first burr gasket 3, the grounding area of the photovoltaic net rack, the second burr gasket 4, the second gasket 5 and the second nut 6 in sequence, and to clamp the first burr gasket 3 and the second burr gasket 4 by rotating the first nut 1 and / or the second nut 6, and to drive the first burr gasket 3 and the second burr gasket 4 to rotate under the joint action of the clamping force and the torque in the process of further rotating the first nut 1, the second nut 6 or the screw rod 7. The burrs on the two burr gaskets are like sandpaper, which constantly rub the surface of the grounding area of the photovoltaic net rack until the protective paint or the anticorrosive coating is completely removed to expose the metal layer.

[0038] Compared with the traditional manual removal method, the present scheme greatly reduces the labor intensity of the construction personnel, and the construction personnel only need to rotate the screw rod 7, the first nut 1 and / or the second nut 6 to complete the removal work of the paint or the coating without the need for tedious manual operation. Secondly, the construction efficiency is significantly improved. The rotary friction method of the burr gasket makes the removal speed of the paint or the coating faster and more thorough, greatly shortening the construction period. In addition, the present scheme also has the characteristics of convenient operation and small difficulty. The whole device is compact in design and reasonable in structure, and the construction personnel can easily operate without professional skills.

[0039] The parts of the tool for offshore photovoltaic containing outer sawtooth burr gasket of the present disclosure and their specific details will be described in detail as follows:

[0040] The materials of the first nut 1 and the second nut 6 can be materials with good hardness, for example, the materials can be metal or alloy. The diameters of the inner rings of the first nut 1 and the second nut 6 can be equal, and the pitches of the threads of the inner walls of the first nut 1 and the second nut 6 can also be equal. The first nut 1 and the second nut 6 can be arranged in parallel and opposite distribution.

[0041] The material of the first gasket 2 can be a material with strong hardness, for example, the material can be metal, alloy or stainless steel, etc. The first gasket 2 is located between the first nut 1 and the second nut 6, the surface of the first gasket 2 can be a plane, and the central area of the first gasket 2 is provided with a through hole penetrating through the first gasket 2 along the thickness direction of the first gasket 2, for example, the first gasket 2 can be a flat washer.

[0042] The second gasket 5 can be made of the same material as the first gasket 2, and is located between the first gasket 2 and the second nut 6. The surface of the second gasket 5 can also be flat, and the central region of the second gasket 5 is provided with a through hole penetrating the second gasket 5 along the thickness direction of the second gasket 5. For example, the second gasket 5 can be a flat gasket. In some embodiments of the present disclosure, the diameter of the second gasket 5 is equal to the diameter of the first gasket 2, and the diameter of the through hole in the second gasket 5 is also equal to the diameter of the through hole in the first gasket 2.

[0043] The first burr gasket 3 can be made of a material with certain rigidity and wear resistance, for example, it can be a metal sheet, an alloy sheet or a gasket material with special surface treatment. The first burr gasket 3 is located between the first gasket 2 and the second gasket 5.

[0044] In an exemplary embodiment of the present disclosure, the first burr gasket 3 can include a gasket body and serrated patterns on the edge region thereof, and the gasket body is provided with a central hole for the screw rod 7 to pass through. In some embodiments of the present disclosure, the serrated patterns are composed of a plurality of serrations which are annularly distributed along the outer periphery of the gasket body and protrude from the surface of the gasket body. Such design aims to increase the friction between the contact surfaces (such as the contact region of the photovoltaic grid frame and the first burr gasket 3) by the serrated structure, so as to quickly and effectively remove the paint or corrosion-resistant coating on the surface of the contact region in contact with the first burr gasket 3. The shape of the first burr gasket 3 is adapted to the first gasket 2 and the second gasket 5, for example, it can be annular, and the outer ring diameter thereof is consistent with the diameter of the first gasket 2 and the second gasket 5, ensuring the neatness and stability during assembly. In some embodiments of the present disclosure, in order to ensure the rigidity of the first burr gasket 3, the gasket body and the serrated patterns can be of an integrated structure.

[0045] The second burr gasket 4 is made of the same or similar material as the first burr gasket 3, and also has the function of enhancing friction. The second burr gasket 4 can also include a gasket body and serrated patterns on the edge region of the gasket body. The structure of the second burr gasket 4 is similar to that of the first burr gasket 3, and the serrated patterns are also annularly distributed and protrude from the surface of the gasket body. The second burr gasket 4 is located between the first burr gasket 3 and the second gasket 5, and can act on both sides of the contact region of the photovoltaic grid frame through the first burr gasket 3 and the second burr gasket 4, which helps to improve the removal efficiency of the paint or corrosion-resistant coating on both sides of the surface of the contact region through the synchronous action of the first burr gasket 3 and the second burr gasket 4.

[0046] In some embodiments of the present disclosure, the sawtooth pattern of the second burr gasket 4 is arranged opposite to the sawtooth pattern of the first burr gasket 3, ensuring that the two can be tightly fitted when assembled, so as to provide uniform friction to both sides of the grounding area of the photovoltaic grid. In terms of diameter size, the second burr gasket 4 is coordinated with the first burr gasket 3 and the first gasket 2 and the second gasket 5 to maintain consistent diameter specifications, facilitating installation and maintaining overall aesthetics, while ensuring tight fitting between components for optimal results.

[0047] The screw rod 7 can pass through the first nut 1, the first gasket 2, the first burr gasket 3, the second burr gasket 4, the second gasket 5, and the second nut 6 in sequence, and is threadedly connected with at least the first nut 1 and the second nut 6, thereby forming a stable and reliable connection structure. This series connection method not only ensures tight fitting between components, but also enables the gaskets and nuts to fully exert their function of enhancing friction through the tightening action of the screw rod 7, the first nut 1, or the second nut 6.

[0048] In use, the first nut 1, the first gasket 2, and the first burr gasket 3 can be arranged on one side of the grounding area of the photovoltaic grid, and the second nut 6, the second gasket 5, and the second burr gasket 4 can be arranged on the other side of the grounding area of the photovoltaic grid, so that the screw rod 7 passes through the first nut 1, the first gasket 2, the first burr gasket 3, the grounding area of the photovoltaic grid, the second burr gasket 4, the second gasket 5, and the second nut 6 in sequence. By rotating the first nut 1 and / or the second nut 6, the first burr gasket 3 and the second burr gasket 4 can be clamped, and during further rotation of the first nut 1, the second nut 6, or the screw rod 7, the first burr gasket 3 and the second burr gasket 4 can be rotated under the combined action of clamping force and torque. The burrs on the two burr gaskets constantly rub the surface of the grounding area of the photovoltaic grid like sandpaper until the protective paint or corrosion-resistant coating is completely removed, exposing the metal layer.

[0049] Compared with the traditional manual removal method, the present scheme greatly reduces the labor intensity of construction personnel, who only need to rotate the screw rod 7, the first nut 1, and / or the second nut 6 to complete the removal of the paint or coating, without the need for tedious manual operations. Secondly, the construction efficiency is significantly improved. The rotational friction of the burr gaskets makes the removal of the paint or coating faster and more thorough, greatly shortening the construction period.

[0050] In an exemplary embodiment of the present disclosure, the first burr gasket 3 is connected to the first gasket 2, and the first gasket 2 is connected to the first nut 1; the second burr gasket 4 is connected to the second gasket 5, and the second gasket 5 is connected to the second nut 6. This connection relationship can be detachable or permanently welded.

[0051] In some embodiments of the present disclosure, the first burr gasket 3 is detachably connected with the first gasket 2, and the first gasket 2 is detachably connected with the first nut 1; the second burr gasket 4 is detachably connected with the second gasket 5, and the second gasket 5 is detachably connected with the second nut 6. For example, the detachable connection in the present disclosure can be achieved by bolts or buckles. The detachable connection between the components facilitates easy disassembly and reassembly when installing, maintaining or replacing the components, thereby improving the flexibility and maintainability of the system.

[0052] In some embodiments of the present disclosure, the first burr gasket 3 is connected with the first gasket 2 through a welded connection, and the first gasket 2 is connected with the first nut 1 through a welded connection; the second burr gasket 4 is connected with the second gasket 5 through a welded connection, and the second gasket 5 is connected with the second nut 6 through a welded connection. That is, the first burr gasket 3 and the first gasket 2, the first gasket 2 and the first nut 1, the second burr gasket 4 and the second gasket 5, and the second gasket 5 and the second nut 6 can be connected by welding, which not only enhances the connection strength between the two, but also avoids loosening due to vibration or external force during use, thereby ensuring the firmness and stability of the entire connection system.

[0053] In some embodiments of the present disclosure, the connection mode between different components can also be flexibly selected according to actual needs. For example, the first burr gasket 3 is connected with the first gasket 2 through a welded connection, and the first gasket 2 is detachably connected with the first nut 1; the second burr gasket 4 is connected with the second gasket 5 through a welded connection, and the second gasket 5 is detachably connected with the second nut 6. Alternatively, the first burr gasket 3 is detachably connected with the first gasket 2, and the first gasket 2 is connected with the first nut 1 through a welded connection; the second burr gasket 4 is detachably connected with the second gasket 5, and the second gasket 5 is connected with the second nut 6 through a welded connection. Such flexible and diverse connection modes not only meet the use requirements in different scenarios, but also improve the adaptability and expandability of the entire connection system.

[0054] Other embodiments of the present disclosure will be apparent to those skilled in the art upon consideration of the specification and practice of the concepts disclosed herein. The present application is intended to cover any and all variations of the present disclosure comprising adaptations, modifications, and equivalents of the concepts disclosed herein, following in general the principles of the present disclosure and including such departures from the present disclosure that come within the known and customary practice of the art to which the present disclosure pertains.
