Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic truss technology, specifically to a modular structure for shallow-water marine photovoltaic spatial planar trusses. Background Technology

[0002] my country possesses abundant shallow water resources in its tidal flats, providing ample space for the large-scale development of offshore photovoltaic (PV) projects. However, the construction of such projects is extremely challenging due to multiple factors, including frequent tidal changes, low bearing capacity of silt-covered foundations, short operational windows, significant wave disturbances, and restrictions on the access of large equipment. Traditional design schemes have several fatal flaws during construction. While continuous beam schemes use less steel structure, they require assembly of components at sea and demand high precision in pile driving. Traditional large-module steel pipe pile schemes are limited by shallow water depth, operational space, and the accessibility of large equipment. More importantly, traditional schemes generally suffer from a disconnect between design and construction, with structural selection not fully considering the characteristics of shallow water construction equipment and conditions. This results in significant difficulties in project implementation and high costs, severely hindering the large-scale advancement of tidal flat PV projects.

[0003] Existing technology uses a modular truss structure to provide an installation base for photovoltaic panels. The spliced ​​truss is assembled and welded on the beach and then hoisted and installed on the mudflats. However, the truss needs to be supported by underwater piles. Individual piles and trusses are prone to displacement due to the influence of water flow and strong winds, which results in poor stability of the installed photovoltaic panels. In addition, there is a height difference after the underwater piles are installed, which creates gaps between the truss and the piles, making the truss prone to swaying. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a modular structure for a shallow-water offshore photovoltaic spatial planar truss.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a modular structure of a spatial planar truss for photovoltaic power generation in shallow waters, comprising multiple trusses, an installation frame fixedly connected to the upper end of the truss, a connecting component provided at the lower end of the truss, an installation component provided at the lower end of the connecting component, and an adjustment component provided on the surface of the connecting component.

[0006] The connecting assembly includes multiple inserts and columns. The inserts are fixedly connected to the four corners of the lower surface of the truss. The upper surface of the column has four slots, and the inserts are inserted into the slots. The upper surface of the column has an annular groove, and the surface of the annular groove has multiple connecting arc plates. Horizontal bars and vertical bars are fixedly connected to the surface of the connecting arc plates respectively. A collar is movably fitted onto the surface of the connecting arc plates. The lower outer wall of the collar has four slots. The surface of the column has four fixing holes. The surface of the insert has a threaded groove, and bolts are threaded into the threaded grooves. The bolts are inserted into the fixing holes.

[0007] Specifically, two longitudinally adjacent trusses are connected to the upper end of the same column, while two laterally adjacent trusses are set separately.

[0008] Specifically, the crossbar and the longitudinal bar are respectively engaged in the slots arranged laterally and longitudinally on the surface of the collar, and the connecting arc plate is tightly engaged between the collar and the collar slot.

[0009] Specifically, the installation assembly includes multiple foundation piles and a snap-fit ​​groove on the lower surface of the column. A plug-in post is fixedly connected to the upper surface of the foundation pile, and the upper end of the plug-in post is inserted into the snap-fit ​​groove. A clamping groove is formed on the upper surface of the plug-in post. Two vertical grooves are formed on the lower surface of the column. Multiple support plates are snapped into the clamping grooves. Insertion holes are formed at both ends of the support plates. Two fixing blocks are symmetrically fixedly connected to the surface of the column. Through holes are formed on the surface of the fixing blocks. Plug-in bolts are inserted into the through holes, and the lower ends of the plug-in bolts are inserted into the insertion holes.

[0010] Specifically, the clamping groove corresponds to the vertical groove, and the two ends of the support plate are engaged with the upper inner wall of the vertical groove.

[0011] Specifically, the adjusting assembly includes multiple sleeves. Two threaded grooves are symmetrically opened on the inner wall of each sleeve. Threaded posts are threaded to both ends of each threaded groove. A snap-fit ​​arc plate is fixedly connected to the other end of each threaded post. Four fixing rods are equidistantly embedded on the outer wall of each sleeve. A sliding ring is movably sleeved on the surface of each threaded post. Four positioning holes are equidistantly opened on the surface of each sliding ring. The two ends of each fixing rod are inserted into the positioning holes.

[0012] Specifically, the snap-fit ​​arc plate snaps into the inside of the collar, and the threaded post snaps into the groove on the surface of the collar.

[0013] The beneficial effects of this invention are:

[0014] (1) The modular structure of the shallow sea photovoltaic space planar truss described in this invention enables the rapid splicing of trusses and columns through connecting components. The longitudinal trusses share columns to improve the overall structure, while the transverse trusses are separated to adapt to the shallow sea terrain and water flow requirements. The tight snap-fit ​​of the collar with the horizontal bar, vertical bar and connecting arc plate enhances the stability of the connection parts, enabling multiple trusses to share piles from north to south, and uniting multiple trusses into a whole. By dispersing the impact on individual piles through the overall truss structure, the problem of traditional trusses being easily affected by water flow and strong winds and shifting is effectively solved, thus improving the stability of photovoltaic panels after installation.

[0015] (2) The modular structure of the shallow sea photovoltaic space planar truss described in this invention effectively compensates for the gap problem caused by the difference in the installation height of the foundation piles by the docking of the plug-in column and the slot, the filling of the gap of the support plate and the fixing of the plug-in bolt, thus avoiding the truss swaying. At the same time, the stable connection between the foundation pile and the column improves the bearing capacity of the structure on the silt base. The adjustment component can be adjusted by the thread to compensate for the installation error, further ensuring the flatness and stability of the structure. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1 to 7 The present invention provides the following technical solutions:

[0027] Example 1: A modular structure of a planar truss for photovoltaic space in shallow waters includes multiple trusses 1. The upper end of the truss 1 is fixedly connected to a mounting frame 2. The lower end of the truss 1 is provided with a connecting component 3. The lower end of the connecting component 3 is provided with a mounting component 4. An adjustment component 5 is provided on the surface of the connecting component 3. The number of mounting frames 2 at the upper end of the truss 1 can be selected according to requirements.

[0028] The connecting component 3 includes multiple inserts 31 and columns 32. The inserts 31 are fixedly connected to the four corners of the lower surface of the truss 1. The upper surface of the column 32 has four slots 33, and the inserts 31 are inserted into the slots 33. The upper surface of the column 32 has an annular groove 34, and the surface of the annular groove 34 has multiple connecting arc plates 35. The surface of the connecting arc plates 35 is fixedly connected to a crossbar 36 and a longitudinal bar 37, respectively. The surface of the connecting arc plates 35 is movably fitted with a collar 38. The lower outer wall of the collar 38 has four slots 39. The surface of the column 32 has four fixing holes 310. The surface of the inserts 31 has a threaded groove 311, and the threaded groove 311 is threaded with a bolt 312, which is inserted into the fixing hole 310.

[0029] Two longitudinally adjacent trusses 1 are connected to the upper end of the same column 32, while two laterally adjacent trusses 1 are set separately. By sharing the column 32 with the longitudinal trusses 1, the overall structural correlation and stability are improved, the number of columns 32 used is reduced to reduce costs, and the lateral trusses 1 are set separately to adapt to the undulations of shallow water terrain. At the same time, water flow channels are reserved to reduce the impact of wave forces on the trusses 1 and the overall structure.

[0030] The horizontal bar 36 and the vertical bar 37 are respectively engaged in the slots 39 arranged laterally and longitudinally on the surface of the collar 38. The connecting arc plate 35 is tightly engaged between the collar 38 and the ring groove 34. Through the precise engagement of the horizontal bar 36 and the vertical bar 37 with the slots 39 of the collar 38, and the tight fit of the connecting arc plate 35 between the collar 38 and the ring groove 34, the rigid fixation of components such as the insert block 31, the column 32, and the connecting arc plate 35 in the connecting assembly 3 is achieved, preventing relative displacement of the components and enhancing the wind load and water flow disturbance resistance of the connection between the truss 1 and the column 32.

[0031] In use, the truss 1 is first modularly assembled at a designated location in the shallow water. Then, the truss 1 is transported to the installation area using hoisting equipment. The four corner blocks 31 on the lower surface of the truss 1 are aligned with the slots 33 on the upper surface of the column 32 and inserted into the slots 33 to achieve initial positioning of the truss 1 and the column 32. For two longitudinally adjacent trusses 1, they share the same column 32, meaning the corner blocks 31 of the two trusses 1 are inserted into the four slots 33 of the same column 32 respectively. Laterally adjacent trusses 1 remain separated, leaving space for the photovoltaic panels to extend. Next, the collar 38 is fitted onto the surface of the connecting arc plate 35, so that the transverse groove 39 on the collar 38 is engaged with the horizontal bar 36 and the longitudinal groove 39 is engaged with the vertical bar 37, ensuring that the connecting arc plate 35 is tightly fitted between the collar 38 and the ring groove 34, completing the installation of the connecting component 3, realizing a stable connection between the truss 1 and the column 32, and uniting multiple trusses 1 into a whole through the connecting component 3, realizing the north-south common pile of multiple ring grooves 34, and dispersing the impact on individual piles through the overall truss 1, greatly reducing the displacement of individual piles and trusses 1.

[0032] Example 2: The technical solution of this example, which differs from that of Example 1, includes: the installation component 4 includes multiple foundation piles 41 and a snap-fit ​​groove 43 on the lower surface of the column 32. The upper surface of the foundation piles 41 is fixedly connected to a plug-in post 42, the upper end of the plug-in post 42 is inserted into the snap-fit ​​groove 43, the upper surface of the plug-in post 42 is provided with a clamping groove 44, the lower surface of the column 32 is provided with two vertical grooves 45, multiple support plates 46 are snapped into the clamping groove 44, both ends of the support plate 46 are provided with insertion holes 47, two fixing blocks 48 are symmetrically fixedly connected to the surface of the column 32, the surface of the fixing blocks 48 is provided with through holes 49, the through holes 49 are inserted with plugs 410, and the lower end of the plugs 410 is inserted into the insertion holes 47.

[0033] The clamping groove 44 corresponds to the vertical groove 45. The two ends of the support plate 46 are engaged with the upper inner wall of the vertical groove 45. By aligning the clamping groove 44 of the plug-in column 42 with the vertical groove 45 of the column 32, a precise installation positioning reference is provided for the support plate 46, ensuring that the two ends of the support plate 46 are stably engaged in the vertical groove 45, avoiding the support plate 46 from shifting under force, and further improving the flatness and load-bearing stability of the connection between the column 32 and the plug-in column 42.

[0034] In use, first drive the foundation pile 41 into the shallow silt base to a specified depth to ensure that the foundation pile 41 is installed firmly. According to the height difference after the foundation pile 41 is installed, select an appropriate number of support plates 46 and snap the support plates 46 into the groove 44 of the plug-in column 42. At the same time, align the two ends of the support plates 46 with the vertical groove 45 on the lower surface of the column 32 and snap them into the upper inner wall of the vertical groove 45. Fill any gaps that may exist between the column 32 and the plug-in column 42 with the support plates 46. Then, align the snap-in groove 43 on the lower surface of the column 32 with the upper end of the plug-in column 42 and insert the plug-in column 42 into the snap-in groove 43 to complete the initial connection between the column 32 and the foundation pile 41. Finally, pass the plug bolt 410 through the through hole 49 on the fixing block 48 and insert it into the insertion hole 47 at both ends of the support plate 46 to achieve a firm fixation of the column 32, the support plate 46 and the foundation pile 41, and complete the assembly of the installation component 4.

[0035] Example 3: The technical solution of this example, which differs from that of Example 2, includes: the adjusting component 5 includes multiple sleeves 51, two threaded grooves 52 are symmetrically opened on the inner wall of the sleeves 51, threaded posts 53 are threaded to both ends of the threaded grooves 52, and a snap-fit ​​arc plate 54 is fixedly connected to the other end of the threaded posts 53. Four fixing rods 55 are equidistantly embedded on the outer wall of the sleeves 51, a sliding ring 56 is movably sleeved on the surface of the threaded posts 53, and four positioning holes 57 are equidistantly opened on the surface of the sliding ring 56. The two ends of the fixing rods 55 are inserted into the positioning holes 57.

[0036] The snap-fit ​​arc plate 54 snaps into the inside of the collar 38, and the threaded post 53 snaps into the groove 39 on the surface of the collar 38. By the snap-fit ​​arc plate 54 fitting against the inner surface of the collar 38 and the threaded post 53 snapping into the groove 39 of the collar 38, the adjusting component 5 and the collar 38 and connecting arc plate 35 of the connecting component 3 form a rigid linkage, ensuring that the adjusting force is accurately transmitted to the connection part of the truss 1 and the column 32, while enhancing the overall rigidity of the connecting component 3 and improving the deformation resistance of the truss 1.

[0037] In use, after the connecting component 3 is installed, align the snap-fit ​​arc plate 54 of the adjusting component 5 with the inside of the collar 38, so that the threaded post 53 snaps into the corresponding groove 39 on the surface of the collar 38. According to the flatness requirements of the structural installation, rotate the sleeve 51, and use the threaded groove 52 on the inner wall of the sleeve 51 to engage with the threaded post 53 to adjust the extension length of the threaded post 53 at both ends. Apply lateral pressure to the collar 38 through the snap-fit ​​arc plate 54, thereby fine-tuning the position of the connecting component 3 and compensating for installation errors. After adjusting to the appropriate position, move the sliding ring 56 so that the positioning hole 57 on the surface of the sliding ring 56 is aligned with the fixing rod 55 on the outer wall of the sleeve 51. Insert both ends of the fixing rod 55 into the positioning hole 57 to fix the position of the threaded post 53 and prevent the threaded post 53 from rotating under force, ensuring the fixing effect of the adjusting component 5 and further improving the stability and flatness of the overall structure.
