Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and particularly relates to an installation bracket, a method and a photovoltaic power generation device for offshore photovoltaic. Background Art

[0002] Offshore photovoltaic is a technology that installs a solar photovoltaic power generation system in the ocean or nearshore waters, combining the characteristics of solar power generation and offshore facilities, and using ocean space for large-scale solar power generation. When installing an offshore photovoltaic bracket, the frame of the photovoltaic panel part is built on land, transported to the pile foundation position by a ship, and the frame part is docked and assembled with the pile foundation through a crane, so as to complete the overall installation work of the offshore photovoltaic bracket. However, due to the influence of wind and waves on the ship, when fixing the connection structure at the bottom of the offshore photovoltaic bracket to the pile foundation, the photovoltaic bracket will shake, which is not conducive to the development of the overall installation work of the offshore photovoltaic bracket, thus affecting the overall stability and safety of the offshore photovoltaic bracket after installation, and resulting in poor installation effects.

[0003] In order to solve the influence of the shaking phenomenon caused by wind and waves on the installation, holes are opened at the upper end of the pile foundation, and structures such as tapered heads are arranged at the connection between the photovoltaic installation bracket and the pile foundation, so as to realize the rapid docking of the tapered head and the pile foundation, and solve the problem that the shaking phenomenon affects the installation. In the current technology, during installation, the tapered head and the pile foundation can be quickly docked. However, the connection between the tapered head and the hole on the pile foundation cannot be stably connected, which reduces the connection stability to a certain extent, and only auxiliary connection structures can be used for reinforcement, making the overall structure of the photovoltaic installation bracket complex and the connection stability with the pile foundation not high. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an installation bracket, a method and a photovoltaic power generation device for offshore photovoltaic. Before docking, the fastening block is located in the limiting groove and does not affect the movement of the tapered part into the hole. During docking, the cross bar extending to the outside of the tapered part contacts the upper end of the side wall of the hole on the pile foundation. Under the action of gravity, as the tapered part enters the hole of the pile foundation, the cross bar rises relative to the tapered part along the sliding groove. Through the driving of thread engagement, the screw rotates, and the screw rotation drives the driving disk to rotate. The scroll rack on the driving disk meshes with the tooth block of the driven block, so that the driven block moves radially outward along the tapered part. Finally, the fastening block contacts the inner wall of the hole, realizing the stable connection between the docking component and the inner wall of the hole, and improving the connection stability between the bracket and the pile foundation without the need for complex auxiliary fastening components.

During docking, the cross bar extending outside the conical part contacts the upper end of the side wall of the hole opened on the pile foundation.

[0019] To achieve the above object, in a third aspect, the present invention further provides a photovoltaic power generation device, adopting the following technical solutions:

[0020] A photovoltaic power generation device uses the installation bracket for offshore photovoltaic as described in the first aspect.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, the docking assembly includes a first connecting plate and a conical portion provided on the first connecting plate. A chute and a limiting groove are formed on the outer wall of the conical portion. The conversion member includes a screw rod rotatably provided on the first connecting plate. The driving member includes a driving disk provided on the screw rod and a scroll rack formed on the driving disk. The driven member includes a collar and a cross bar provided on the collar. The collar is sleeved on the screw rod, and a mutually meshing thread is provided between the collar and the screw rod. The cross bar is slidably provided in the chute and extends through the chute to the outside of the conical portion. The limiting member includes a fastening block and a driven block vertically connected to the fastening block by a connecting rod. The limiting member is slidably provided in the limiting groove, the driven block is slidably provided in the conical portion along the radial direction of the conical portion, and a tooth block is provided on the driven block, and the tooth block meshes with the scroll rack. Before docking, the fastening block is located in the limiting groove and does not affect the movement of the conical portion into the hole. During docking, the cross bar extending to the outside of the conical portion contacts the upper end of the side wall of the opening in the pile foundation. Under the action of gravity, as the conical portion enters the opening of the pile foundation, the cross bar rises relative to the conical portion along the chute. The rotation of the screw rod is driven by the meshing of the thread, and the rotation of the screw rod drives the driving disk to rotate. The scroll rack on the driving disk meshes with the tooth block of the driven block, so that the driven block moves radially outward along the conical portion. Finally, the fastening block contacts the inner wall of the opening, realizing the stable connection between the docking assembly and the inner wall of the opening. On the basis of not requiring a complex structure of auxiliary fastening members, the stability of the connection between the bracket and the pile foundation is improved.

[0023] 2. By setting the docking assembly to cooperate with the pile foundation, the present invention utilizes the inner hole of the pile foundation, facilitating the alignment and positioning of the overall bracket with the pile foundation, improving the installation accuracy, reducing the installation difficulty, and enhancing the installation efficiency of the offshore photovoltaic bracket.

[0024] 3. By arranging multiple groups of limiting members in the docking assembly, during the docking process of the docking assembly and the pile foundation, affected by the downward gravity of the overall bracket itself and the upward supporting force of the pile foundation, under the dual driving of the two, the multiple groups of limiting members can evenly expand around the inner hole of the pile foundation. The expanded limiting members can firmly abut against the inner wall of the inner hole of the pile foundation from four directions, thereby increasing the connection stability between the overall bracket and the pile foundation, achieving the purpose of initially fixing the bracket and the pile foundation, and further preventing the bracket from shaking after docking with the pile foundation, facilitating the continuation of subsequent installation work.

[0025] 4. The present invention is provided with receiving members on both sides below the bracket, and two groups of receiving members are provided on both sides below the receiving members. The receiving members can follow the docking amplitude of the docking assembly and the pile foundation during the docking process, embrace the pile foundation from both sides, and finally embrace both sides of the pile foundation, and cooperate with the pile foundation to provide support from below for the overall bracket, further enhancing the stability of the bracket installation work and improving the installation effect.

Detailed implementation mode

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanations for the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0040] Embodiment 1:

[0041] As described in the background art, due to the influence of wind and waves on the ship, when fixing the connection structure between the bottom of the offshore photovoltaic support and the pile foundation, the photovoltaic support will shake, which is not conducive to the overall installation work of the offshore photovoltaic support. Based on this, as Figure 1 and Figure 10 shown, this embodiment provides an installation support for offshore photovoltaic, including a docking component 100 for docking with the pile foundation 300, and a support component 200 for supporting the photovoltaic panel 400. The docking component 100 and the support component 200 can be connected by welding, bolt connection or other connection methods.

[0042] During operation, the pile foundation 300 can be fixed to the corresponding sea area in advance, and holes are opened at the top of the pile foundation 300 for docking with the docking component 100; on land, the docking component 100, the support component 200 and the photovoltaic panel 400 are connected and fixed into a whole, and the whole is transported to the corresponding sea area by ship and installed on the pile foundation 300 by hoisting.

[0043] As Figure 1 、 Figure 2and Figure 3 As described above, the docking component 100 includes a connecting component 101, a conversion component 102, a driving component 103, a driven component 104, a limiting component 105, etc.

[0044] The connecting component 101 is used to connect the support component 200 and dock with the pile foundation 300. As Figure 3 shown, the connecting component 101 includes a conical portion 1011, a first connecting plate 1012, a sliding groove 1013, a limiting groove 1014, etc.

[0045] The conical portion 1011 can be set as a cavity structure for accommodating other structures of the connecting component 101; the conical portion 1011 is used to dock with the opening on the pile foundation 300 and can be smoothly docked under the shaking caused by sea waves. The first connecting plate 1012 is used to connect with the support component 200. The first connecting plate 1012 is arranged at the end with a larger cross-sectional area of the conical portion 1011. The first connecting plate 1012 can be set as a circular plate, a rectangular plate or a plate of other shapes. Both the sliding groove 1013 and the limiting groove 1014 are opened on the side wall of the conical portion 1011; the sliding groove 1013 can be one, two symmetrical ones or more. When set as two symmetrical ones, the two cross bars 1042 can be evenly stressed to improve stability; the limiting groove 1014 can be one or multiple evenly distributed ones, such as four. When the limiting groove 1014 is set as multiple ones, good fixation with the opening can be achieved through multiple fastening blocks 1052 in the circumferential direction; the sliding groove 1013 can be opened as a long groove with both ends not open, allowing only the cross bar 1042 to move within a certain distance. The limiting groove 1014 can be set as a long groove with one end open, which is convenient for the setting of the limiting component 105. And a radial sliding groove is opened at one end of the limiting groove 1014 close to the first connecting plate 1012 for sliding connection with the driven block 1053 in the radial direction. Optionally, the top end of the limiting groove 1014 is in the shape of a cross notch, which matches the cross-sectional structure of the driven block 1053. Therefore, the driven block 1053 is limited in the vertical direction, so that the driven block 1053 can only slide horizontally along the limiting groove 1014.

[0046] As Figure 2 、 Figure 4 and Figure 6As shown, the conversion member 102 includes a screw rod 1021, a screw head 1022, a spiral guide groove 1023, etc. One end of the screw rod 1021 penetrates through a through hole in the first connecting plate 1012. A screw head 1022 is provided at one end of the screw rod 1021. The screw rod 1021 is rotatably arranged on the first connecting plate 1012 through a bearing or other components. A spiral guide groove 1023 is formed on the screw rod 1021. The spiral guide groove 1023 is used to engage with the internal thread of the collar 1041.

[0047] As Figure 2 and Figure 5 shown, the driving member 103 includes a driving disk 1031 and a scroll rack 1032 provided on the driving disk 1031. The driving disk 1031 is fixedly connected to the screw rod 1021. When the screw rod 1021 rotates, the driving disk 1031 rotates. The scroll rack 1032 engages with a tooth block provided on the driven block 1053. When the driving disk 1031 rotates, under the action of the scroll rack 1032 and the tooth block, the driven block 1053 can be driven to move radially.

[0048] As Figure 2 , Figure 4 and Figure 6 shown, the driven member 104 includes a collar 1041, a cross bar 1042 and a connecting bead 1043. An internal thread matching the spiral guide groove 1023 is formed inside the collar 1041. A connecting bead 1043 is arranged between the spiral guide groove 1023 and the thread of the collar 1041, improving the flexibility of transmission. The connecting bead 1043 can be set as a ball. The cooperation of the spiral guide groove 1023, the thread of the collar 1041 and the connecting bead 1043 can be realized by referring to structures such as a lead screw and nut. During use, when the upper walls on both sides of the opening of the pile foundation 300 drive the cross bar 1042 to move upward relative to the conical portion 1011, the spiral guide groove 1023, the thread of the collar 1041 and the connecting bead 1043 cooperate to drive the cross bar 1042 to rotate, thereby driving the driving disk 1031 to rotate.

[0049] As Figure 2 , Figure 4 , Figure 8 and Figure 9As shown, the limiting member 105 includes a connecting rod 1051, a fastening block 1052, a driven block 1053, a tooth block 1054, etc. The connecting rod 1051 is used to connect the fastening block 1052 and the driven block 1053. The surface of the connecting rod 1051 facing the outside of the conical portion 1011 is an inclined surface. Specifically, the thickness of the connecting rod 1051 near the driven block 1053 is less than that of the other end, which can better match the taper of the conical portion 1011. The fastening block 1052 is perpendicular to the driven block 1053. A tooth block 1054 that cooperates with the scroll rack 1032 is provided at the upper end of the driven block 1053, and a slide rail is provided on the driven block 1053 for sliding connection with the radial slide groove on the limiting groove 1014. A corrugated structure is provided on the surface of the fastening block 1052 facing the outside of the conical portion 1011, which can be well fixed to the inner wall of the opening of the pile foundation 300. The corrugated structure can adopt wavy lines, multiple parallel protrusions or other irregular concave-convex mechanisms.

[0050] Specifically, through the setting of the docking assembly 100 and the support assembly 200. As Figure 1 described, before docking, the fastening block 1052 is located in the limiting groove 1014, which does not affect the movement of the conical portion 1011 into the hole. As Figure 4 、 Figure 8 and Figure 9 shown, during docking, the cross bar 1042 extending to the outside of the conical portion 1011 contacts the upper end of the side wall of the opening on the pile foundation 300. Under the action of gravity, as the conical portion 1011 enters the opening, the cross bar 1042 rises relative to the conical portion 1011 along the slide groove 1013. Through the drive of screw meshing, the screw 1021 rotates. The rotation of the screw 1021 drives the drive disk 1031 to rotate. The scroll rack 1032 on the drive disk 1031 meshes with the tooth block 1054 of the driven block 1053, so that the driven block 1053 moves radially along the conical portion 1011. Finally, the fastening block 1052 contacts the inner wall of the opening, realizing the stable connection between the docking assembly 100 and the inner wall of the opening. On the basis of not requiring complex structural auxiliary fastening members, the stability of the connection between the bracket and the pile foundation 300 is improved. In this embodiment, the docking assembly 100 can form a connection relationship with the inner wall of the opening of the pile foundation 300 from multiple directions, thereby increasing the connection stability between the overall bracket and the pile foundation 300, achieving the purpose of initially fixing the bracket and the pile foundation 300, and further preventing the bracket from shaking after docking with the pile foundation 300, facilitating the continuation of subsequent installation work.

[0051] Embodiment 2:

[0053] The receiving member 201 includes a second connecting plate 2011, a cross beam 2012, a receiving groove 2013, etc. The second connecting plate 2011 can be connected to the first connecting plate 1012. A cross beam 2012 is provided on the first connecting plate 1012. The cross beam 2012 cooperates with structures such as vertical beams to support and fix the photovoltaic panel 400; the receiving groove 2013 is opened on the cross beam 2012 for receiving components such as a slider 2033 and a slide bar 2021.

[0054] The connecting member 202 includes a slide bar 2021, a slide bar head 2022, a chute 2023, etc. The slide bar 2021 can be provided on the cross beam 2012, and a part or all of it is located in the receiving groove 2013; the slide bar head 2022 can improve the connection stability of the slide bar 2021. The chute 2023 is opened in the receiving groove 2013 and slidably cooperates with the slider 2033.

[0055] The auxiliary fastener 203 includes an inclined bar 2031, a hinge member 2032, a slider 2033, a reinforcing ring 2034, a connection groove 2035, etc. The reinforcing ring 2034 is used to surround the pile foundation 300 and improve the connection stability through an auxiliary reinforcement method; the reinforcing ring 2034 includes two semi-circular structures, and the connection groove 2035 can be used as a connecting member for the two semi-circular structures, and cooperate with bolts, snap joints or other connecting members to connect the two semi-circular structures. The inclined bar 2031 is used to connect the reinforcing ring 2034 and the hinge member 2032. The hinge member 2032 can adopt a rotating shaft or other hinge structures to realize the hinge connection between the slider 2033 and the inclined bar 2031; a slide hole is opened on the slider 2033. The slider 2033 is integrally slidably mated with the chute 2023. A sliding hole is opened on the slider 2033, and the sliding hole is slidably connected to the slide bar 2021, which can realize the left and right movement of the reinforcing ring 2034 and the inclined bar 2031, etc., improving the construction flexibility.

[0056] Embodiment 3:

[0057] This embodiment provides an installation bracket for offshore photovoltaic. Different from Embodiment 1 and Embodiment 2, the screw head 1022 is set as a first bevel gear. The slide bar 2021 is set as a threaded rod, and the slide bar head 2022 is set as a second bevel gear meshing with the first bevel gear; the hinge 2032 is arranged on the fixing member to fixedly connect the inclined bar 2031 and the slider 2033. The sliding hole on the slider 2033 is set as a threaded hole, which cooperates with the threaded rod.

[0058] Specifically, before docking, the two semi-circular structures are based on the pile foundation 300; as the screw 1021 rotates, it drives the first bevel gear to rotate, and drives the second bevel gear to rotate, thereby driving the threaded rod to rotate. At this time, under the cooperation of the threaded rod and the threaded hole, the slider 2033 moves closer to the pile foundation 300, and finally the two semi-circular structures surround the pile foundation 300.

[0059] Through this embodiment, the two semi-circular structures can follow the docking amplitude of the docking component 100 and the pile foundation during the docking process of the docking component 100 and the pile foundation, surround the pile foundation 300 from both sides, and finally surround both sides of the pile foundation 300, and cooperate with the pile foundation 300 to provide support for the overall bracket from below, further enhancing the stability of the bracket installation work, improving the installation effect, and being flexible in construction without the need for additional manual operations.

During docking, the cross bar 1042 extending outside the conical part 1011 contacts the upper end of the side wall of the opening on the pile foundation 300. Under the action of gravity, as the conical part 1011 enters the opening, the cross bar 1042 rises relative to the conical part 1011 along the sliding groove 1013. The rotation of the screw 1021 is driven through threaded engagement. The rotation of the screw 1021 drives the driving disk 1031 to rotate.
