Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic power generation, and particularly relates to a bottom-supported pile-stabilizing platform for offshore photovoltaic power generation. Background Art

[0002] Generally, large-scale onshore photovoltaic projects require a large amount of land area and land resources. Offshore photovoltaic power generation is a new energy utilization method and resource development mode, which moves the "photovoltaic power station" from land to the sea. By using photovoltaic technology on the sea to establish a power station, the offshore environment is different from that on land. Under the same lighting conditions, the advantages of the open sea surface, no obstacles, long sunshine time, and high radiation intensity make the lighting utilization efficiency of offshore photovoltaic projects higher, and the power generation of offshore photovoltaic power stations is significantly improved. The engineering construction conditions of offshore photovoltaic projects are difficult, and the project safety requirements are higher. When constructing the project, it is also necessary to consider the difficulties such as solar energy resources, meteorological and hydrological conditions, engineering geological conditions, landscape design, and three-dimensional development.

[0003] In the actual installation operation of an offshore photovoltaic power station, usually, a pile driving vessel is first used to directly carry out pile sinking operations to fix and position the pile foundation, and then the photovoltaic support is fixed on the pile foundation by means of integral hoisting. To ensure that the photovoltaic support can be quickly and accurately installed on the pile foundation, high precision requirements are imposed on the position and verticality of the pile foundation.

[0004] Currently, a pile driving vessel is usually used to directly carry out pile driving operations. However, during the process of pile foundation sinking operations for actual offshore photovoltaic power generation, due to factors such as the flow of seawater and the influence of wind, the pile driving vessel will shake back and forth, resulting in a large deviation between the actual installation position of the pile foundation and the designed position, and the verticality of the pile foundation cannot be guaranteed. The actual operation accuracy is insufficient, causing the lower pile foundation and the photovoltaic support to be unable to be quickly and accurately docked, affecting the assembly accuracy and construction efficiency.

[0005] Therefore, how to ensure the construction accuracy of the pile foundation for offshore photovoltaic power generation and improve the operation efficiency is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a bottom-supported pile-stabilizing platform for offshore photovoltaic power generation. The bottom pile-stabilizing support can fix the bottom-supported pile-stabilizing platform on the seabed, and the cooperation of the hydraulic support column and the spirit level bubble can make the upper pile-stabilizing platform horizontal, so that the clamping ring is axially vertical, ensuring that the pile foundation maintained is arranged vertically, and ensuring the verticality and installation accuracy of the pile foundation.

[0007] In view of the above technical problems, the technical solution provided by the present utility model is a bottom-supported pile-stabilizing platform for offshore photovoltaic power generation, which includes a bottom pile-stabilizing support, an upper pile-stabilizing platform, and a support structure connecting the two. A plurality of pile grippers and a spirit level bubble are arranged on the upper pile-stabilizing platform. The pile gripper includes two clamping rings arranged at intervals along the vertical direction and coaxially, and a support frame connecting the two clamping rings. The bottom pile-stabilizing support includes a bottom frame, and a plurality of hydraulic support columns are arranged at intervals along the circumference of the bottom frame. The telescopic end of the hydraulic support column extends obliquely downward away from the bottom frame.

[0008] Further, the upper pile-stabilizing platform includes a polygonal frame in the middle. At each included angle of the polygonal frame, a cantilever extending outward away from the center of the polygonal frame is provided, and a pile gripper is arranged on each cantilever.

[0009] Further, a mounting seat is arranged on the side of the cantilever away from the polygonal frame. A mounting plate is rotatably arranged on the mounting seat, and its rotation axis extends vertically. The pile gripper is mounted on the mounting plate.

[0010] Further, a slide rail is arranged on the cantilever, and the slide rail extends outward away from the center of the polygonal frame. The mounting seat is slidably arranged on the slide rail, and a stopper cooperating with the mounting seat in a blocking manner is also arranged on the slide rail.

[0011] Further, the clamping ring is formed by splicing a first clamping ring and a second clamping ring. One ends of the first clamping ring and the second clamping ring facing the support frame are hinged to the support frame, and the other ends are clamped and fixed to each other to realize the opening and closing of the first clamping ring and the second clamping ring.

[0012] Further, two telescopic rods are symmetrically arranged on the opposite sides of the first clamping ring and the second clamping ring. One ends of the two telescopic rods facing the support frame are hinged to the support frame, and the other ends are respectively hinged to the outer sides of the first clamping ring and the second clamping ring.

[0013] Further, the support structure includes a support pile. The lower end of the support pile passes through the center of the bottom frame and extends downward. The hydraulic support column includes a cylinder body and a telescopic column. The inner end of the cylinder body extends obliquely upward and is fixedly connected to the support pile, and the outer end of the cylinder body extends obliquely downward and is connected to the bottom frame.

[0014] Further, the support pile is a hydraulic telescopic pile. The hydraulic telescopic pile includes a bottom cylinder body and an upper column body inserted into the bottom cylinder body. The upper column body is fixedly connected to the upper pile-stabilizing platform, and the inner end of the cylinder body is fixed to the bottom cylinder body.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) By using the hydraulic support columns of the bottom pile-stabilizing bracket, on the one hand, the hydraulic telescopic columns can be embedded in the seabed by hydraulic expansion and contraction, so as to stably fix the bottom pile-stabilizing bracket on the seabed, ensuring the stability and accuracy of construction. On the other hand, by adjusting the telescopic lengths of the hydraulic telescopic columns and cooperating with the spirit level bubble, the precise leveling of the upper pile-stabilizing platform can be achieved. Furthermore, the axes of the two clamping rings of the pile gripper can be made to extend vertically. After the pile foundation of the offshore photovoltaic is passed through the two clamping rings, the pile foundation can be arranged vertically, ensuring the verticality, realizing the positioning and guiding of the pile foundation. At the same time, during the piling operation, the position of the pile foundation will not change with the external environment, realizing the precise pile sinking operation, ensuring the construction accuracy of the pile foundation, and further ensuring the assembly accuracy with the photovoltaic bracket, improving the operation efficiency.

[0017] (2) The pile gripper is installed on the mounting plate, and the mounting plate is rotatably arranged on the mounting seat. Thus, by rotating the mounting plate, the pile gripper can be driven to rotate horizontally within a certain range, adjusting the distance between the pile grippers. Furthermore, the pile-stabilizing platform can be adapted to pile foundation construction operations with different spacings, improving the practicability.

[0018] (3) Slide rails are arranged on the cantilever, and the mounting seat is slidably arranged on the slide rails. Thus, by sliding the mounting seat, the pile gripper can be driven to slide horizontally, changing the position of the pile gripper, improving the practicability of the pile-stabilizing platform.

[0019] (4) By using the opening and closing of the first clamping ring and the second clamping ring, the pile foundation can be conveniently installed on the pile gripper.

[0020] (5) By using the telescopic rod, on the one hand, it can support the first clamping ring and the second clamping ring, ensuring that the shape of the clamping ring will not change during the pile sinking operation, guaranteeing the operation accuracy. On the other hand, it can drive the opening and closing of the first clamping ring and the second clamping ring by using the telescopic rod, improving the automation.

[0021] (6) The support pile is a hydraulic support pile, and the height of the support pile can be changed to adapt to the operation environment of different water depths. Brief Description of the Drawings

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0030] Referring to Figures 1 to 5 , a bottom - mounted pile - stabilizing platform for offshore photovoltaic of the present utility model (hereinafter referred to as the bottom - mounted pile - stabilizing platform) includes a bottom pile - stabilizing support 1, an upper pile - stabilizing platform 2, and a support structure connecting the two. A plurality of pile grippers 4 and a level bubble 5 are arranged on the upper pile - stabilizing platform 2. The pile gripper 4 includes two holding rings 41 arranged at intervals along the vertical direction and coaxially, and a support frame 44 connecting the two holding rings 41. The bottom pile - stabilizing support 1 includes a bottom frame 11, and a plurality of hydraulic support columns 12 are arranged at intervals along the circumferential direction of the bottom frame 11, and the telescopic ends of the hydraulic support columns 12 extend obliquely downward away from the bottom frame 11.

[0031] As shown in Figure 1 and 2 , the upper pile - stabilizing platform 2 includes a polygonal frame 21 in the middle. Specifically, the polygonal frame 21 is a rectangular frame, and a hoisting ring 23 is arranged on each of the two length sides of the polygonal frame 21. At each included angle of the polygonal frame 21, a cantilever 22 extending outward away from the center of the polygonal frame 21 is arranged, and a pile gripper 4 is arranged on each cantilever 22. In this way, four pile grippers 4 with a quadrilateral connection can be arranged on the entire upper pile - stabilizing platform 2, and a set of pile foundations can be positioned at one time, ensuring the operation accuracy and improving the operation efficiency at the same time. In other embodiments, according to actual needs, the polygonal frame can be a triangular frame, a pentagonal frame, etc., and the number of pile grippers can also be set according to actual requirements, such as 3, 5, etc.

[0032] Specifically, as Figure 3 shown, the cantilever 22 includes a fixing frame 221 and a mounting portion 222 along its length direction. The mounting portion 222 is disposed on a side of the fixing frame 221 facing away from the polygonal frame 21, and the fixing frame 221 is fixedly mounted on the polygonal frame 21.

[0033] As Figure 2 、 3 shown in FIGS. 4 and 5, the mounting portion 222 includes two cantilever beams 223 arranged at intervals along the width direction of the cantilever 22. A driving pile opening 103 for a pile foundation to pass through is formed between the two cantilever beams 223 and the fixing frame 221.

[0034] In this embodiment, as Figure 2 、 3 shown, a mounting seat 6 is provided on a side of the cantilever 22 facing away from the polygonal frame 21. A mounting plate 7 is rotatably provided on the mounting seat 6, and its rotation axis extends vertically. Specifically, the lower end of the mounting seat 6 is seated on the two cantilever beams 223. A vertically extending rotating shaft (not shown in the figure) is provided on a side of the mounting seat 6 facing the polygonal frame 21. The upper end of the rotating shaft passes through the mounting plate 7, and a protective cover 9 is fixedly sleeved on the mounting plate 7 corresponding to the position of the rotating shaft. The upper end of the rotating shaft is covered and protected by the protective cover 9.

[0035] As Figure 2 shown, the support frame 44 of the pile gripper 4 is fixedly mounted on an end of the mounting plate 7 facing away from the polygonal frame 21, and both sides of the upper end of the support frame 44 are fixedly connected to the mounting plate 7 through a pull rod 8 respectively. The two holding rings 41 are provided on a side of the support frame 44 facing away from the polygonal frame 21, so that the two holding rings 41 are both arranged above the driving pile opening 103.

[0036] With such a setting, the pile gripper 4 is mounted on the mounting plate 7, and the mounting plate 7 is rotatably provided on the mounting seat 6. Thus, by rotating the mounting plate 7, the pile gripper 4 can be driven to horizontally rotate within a certain range, and the distance between the pile grippers 4 can be adjusted, so that the bottom - sitting pile stabilizing platform can be applied to pile foundation construction operations with different spacings, improving the practicability.

[0037] Preferably, in this embodiment, as Figure 2 shown, slide rails 10 are provided on a side of the cantilever 22 facing away from the polygonal frame 21, and two slide rails 10 are arranged at intervals along the width direction of the cantilever 22. The slide rails 10 extend outward from the center of the side of the cantilever 22 facing away from the polygonal frame 21, that is, the length direction of the slide rails 10 is parallel to the length direction of the cantilever 22.

[0038] Specifically, the two slide rails 10 are respectively arranged at the upper ends of the two cantilever beams 223, and the lower end of the mounting seat 6 is slidably arranged on the two slide rails 10. In this way, by sliding the mounting seat 6, the pile gripper 4 can be driven to slide horizontally, changing the position of the pile gripper 4, and further improving the practicability of the bottom-sitting pile stabilizing platform.

[0039] As Figure 2 shown, a stopper 101 which is in blocking cooperation with the mounting seat 6 is further arranged on the slide rail 10. In this embodiment, the stopper 101 is a clamping block clamped on the slide rail 10. After the mounting seat 6 is slid to the position, the movement of the mounting seat 6 can be restricted by the stopper 101, and then the position of the pile gripper 4 can be fixed, ensuring the accuracy of the subsequent pile driving operation. In other embodiments, a T-shaped groove can be opened at the upper end of the slide rail, a T-shaped bolt is slidably arranged in the T-shaped groove, and a nut is screwed on the upper end of the T-shaped bolt protruding from the T-shaped groove. The T-shaped bolt and the nut are used to form a stopper to limit and fix the pile gripper.

[0040] In this embodiment, preferably, as Figure 2 shown, the inner diameter of the holding ring 41 is adapted to the outer diameter of the pile foundation. The holding ring 41 is composed of a first holding ring 42 and a second holding ring 43 spliced together. And one end of the first holding ring 42 and the second holding ring 43 facing the support frame 44 is hinged to the support frame 44, and the other ends are clamped and fixed to each other. In this way, the opening and closing of the first holding ring 42 and the second holding ring 43 can be realized, and then it is convenient to install the pile foundation on the pile gripper 4.

[0041] In this embodiment, preferably, two telescopic rods 45 are symmetrically arranged on the opposite sides of the first holding ring 42 and the second holding ring 43. One end of the two telescopic rods 45 facing the support frame 44 is hinged to the support frame 44, and the other ends are respectively hinged to the outer side surfaces of the first holding ring 42 and the second holding ring 43.

[0042] Specifically, the support frame 44 is provided with two hinge plates 46 arranged at intervals in the vertical direction corresponding to the positions of the telescopic rods 45. One end of the telescopic rod 45 facing the support frame 44 is hinged between the two hinge plates 46 through a hinge ball. At the positions corresponding to the telescopic rods 45 on the outer side surfaces of the first holding ring 42 and the second holding ring 43, hinge blocks 47 are arranged. A spherical hinge hole is opened on one side of the hinge block 47 facing the telescopic rod 45. One end of the telescopic rod 45 facing the hinge block 47 is hinged in the spherical hinge hole through a hinge ball. And in this embodiment, the telescopic rod 45 is a hydraulic telescopic rod 45. In this way, on the one hand, the first holding ring 42 and the second holding ring 43 can be supported by the telescopic rod 45 to prevent the first holding ring 42 and the second holding ring 43 from opening during pile driving, ensuring that the shape of the holding ring 41 does not change during the pile sinking operation and ensuring the operation accuracy. On the other hand, the telescopic rod 45 can be used to drive the opening and closing of the first holding ring 42 and the second holding ring 43, improving the degree of automation.

[0043] Of course, in other embodiments, the two ends of the telescopic rod 45 can be hinged to the hinge plate 46 and the hinge block 47 through a vertical hinge axis, and the opening and closing of the first holding ring 42 and the second holding ring 43 can also be realized.

[0044] In this embodiment, if Figure 3 , 4 As shown, the bottom frame 11 is a rectangular frame structure, and the supporting structure includes a supporting pile 3, the lower end of which passes through the center of the bottom frame 11 and extends downward. A hydraulic support column 12 is provided at the angle of each bottom frame 11. The hydraulic support column 12 includes a cylinder 13 and a telescopic column 14, wherein the inner end of the cylinder 13 extends obliquely upward and is fixedly connected to the supporting pile 3, and the outer end of the cylinder 13 extends obliquely downward and is connected to the angle of the bottom frame 11. The telescopic column 14 slides coaxially from the outer end of the cylinder 13 into the cylinder 13, and its outer end extends outward away from the cylinder 13. In this way, the bottom pile stabilizing bracket 1 can be stably connected with the supporting structure, and the hydraulic support columns 12 on all sides can provide effective support for the bottom-seated pile stabilizing platform. The lower end of the supporting pile 3 passes through the bottom frame 11 and extends downward. When actually used, the lower end of the supporting pile 3 can be embedded in the seabed and cooperate with the bottom pile stabilizing bracket 1 to improve the overall stability.

[0045] Preferably, in this embodiment, the support pile 3 is a hydraulic telescopic pile, which includes a bottom cylinder 31 and an upper column 32 inserted in the bottom cylinder 31. The upper end of the upper column 32 is fixedly connected to the center of the polygonal frame 21 of the upper pile stabilizing platform 2. A support beam 102 is fixedly connected between the cantilever 22 and the upper column 32 to improve the connection strength. The inner end of the cylinder 13 of each hydraulic support column 12 is fixed on the bottom cylinder 31. In this way, in actual use, the height of the support pile 3 can be changed by hydraulic telescopic, and the distance between the bottom pile stabilizing bracket 1 and the upper pile stabilizing platform 2 can be changed to adapt to the working environment of different water depths.

[0046] Working process of this application:

[0047] First, use a pile-driving ship to lift the bottom-seated pile-stabilizing platform to the location where piling is required, and use the positioning system to accurately locate the installation position, then lower the bottom-seated pile-stabilizing platform. At the same time, adjust the length of the support pile 3 according to the water depth so that the lower end of the support pile 3 is inserted into the seabed to complete the initial positioning and ensure that after the bottom pile-stabilizing bracket 1 is seated on the seabed, the upper pile-stabilizing platform 2 is above the sea level.

[0048] Start the hydraulic support column 12. On the one hand, the bottom-seated pile stabilizing platform is fixed on the seabed during the process of embedding the hydraulic support column 12 into the seabed. On the other hand, by adjusting the length of each hydraulic support column 12 and coordinating with the level bubble 5, the upper pile stabilizing platform 2 can be adjusted to a horizontal state to ensure that the axis of the holding ring 41 of the pile holder 4 is vertical. The installation of the bottom-seated pile stabilizing platform is completed.

[0049] The telescopic rod 45 starts to shorten, the first clamping ring 42 and the second clamping ring 43 open away from each other, a pile foundation is arranged between the first clamping ring 42 and the second clamping ring 43, the telescopic rod 45 extends in the reverse direction, the first clamping ring 42 and the second clamping ring 43 close towards each other and are clamped and fixed, and at the same time, the pile foundation is clamped on the clamping ring 41, the positioning of the pile foundation is completed, and the upper and lower clamping rings 41 are used to guide the movement of the pile foundation during pile driving.

[0050] The pile pressing operation is carried out to complete the construction and installation of the pile foundation. After the operation is completed, the hydraulic support column 12 retracts, the bottom - mounted pile - stabilizing platform is hoisted to the next position, and the above - mentioned actions are repeated to complete the pile pressing operation of the next group of pile foundations.

[0051] In summary, for the bottom - mounted pile - stabilizing platform of the present utility model, by using the hydraulic support column 12 of the bottom pile - stabilizing bracket 1, on the one hand, the hydraulic telescopic column 14 can be obliquely embedded into the seabed by hydraulic expansion and contraction, so as to stably fix the bottom pile - stabilizing bracket 1 on the seabed, ensuring the stability and accuracy of the construction. On the other hand, by adjusting the telescopic length of each hydraulic telescopic column 14 and cooperating with the spirit level bubble 5, the precise leveling of the upper pile - stabilizing platform 2 can be realized, and further the axes of the two clamping rings 41 of the pile gripper 4 all extend vertically. In this way, after the pile foundation of the offshore photovoltaic is passed through the two clamping rings 41, the pile foundation can be arranged vertically, ensuring the verticality, realizing the positioning and guiding of the pile foundation. At the same time, during the pile driving operation, the bottom - mounted pile - stabilizing platform is fixed on the seabed, and the position of the pile foundation will not change with the external environment, realizing the precise pile sinking operation, ensuring the construction accuracy of the pile foundation, and further ensuring the assembly accuracy between the pile foundation and the photovoltaic support, improving the operation efficiency.

[0052] The bottom - mounted pile - stabilizing platform has a large overall stiffness and good stability. By realizing the construction tasks of multiple pile foundations through a single positioning of the bottom - mounted pile - stabilizing platform, the construction efficiency is greatly improved, and the construction cost is reduced. At the same time, multiple structural units of the bottom - mounted pile - stabilizing platform can be adjusted within a certain range, which can adapt to the pile sinking operations in different marine environments.

Different from Embodiment 1, in this embodiment, when meeting the actual use requirements, the upper pile - stabilizing platform may not be provided with a cantilever. At this time, the pile gripper is directly fixedly installed on the periphery of the polygonal frame, and the clamping ring is exposed outside the polygonal frame.

[0054] Embodiment 3: This embodiment provides a different pile gripper. Different from Embodiment 1, in this embodiment, when meeting the actual use requirements, the clamping ring of the pile gripper is an integral ring - shaped structure. At this time, the inner diameter of the clamping ring is slightly larger than the size of the pile foundation, and an elastic buffer pad is arranged on the inner wall of the clamping ring to fill the small gap between the pile foundation and the clamping ring, ensuring the installation accuracy of the pile foundation.

[0055] Embodiment 4: This embodiment provides a different pile gripper. Different from Embodiment 1, in this embodiment, when meeting the actual use requirements, the telescopic rod can be a pneumatic spring or a hydraulic spring with damping. At this time, at the docking end of the first clamping ring and the second clamping ring, an opening and closing buckle is provided to fix the first clamping ring and the second clamping ring.

For those skilled in the art, various changes and modifications can be made to the present application.
