Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a marine photovoltaic stabilization pile construction platform with self-leveling and fine-tuning positioning functions. Background Technology

[0002] In recent years, as the space for onshore renewable energy utilization has gradually reached saturation, overexploitation has led to a series of problems. Against this backdrop, offshore photovoltaic (PV) has emerged as a new renewable energy power generation method. Compared to traditional ground-mounted PV, offshore PV significantly reduces land occupation while increasing power generation by 5%-10%. This significant increase is attributed to the characteristics of the marine environment, including the unobstructed openness of the water surface, extended sunshine hours, and the effect of light reflection from the water surface.

[0003] However, due to the high precision required for the absolute and relative positions of photovoltaic piles during offshore piling, a four-pile fixed stabilizing platform is generally used to assist in achieving the required accuracy for offshore pile positioning and verticality. This type of stabilizing platform has a fixed pile gripper at each of the four corners of a rectangular frame, providing high precision in controlling the relative positions of the four piles. However, the following problems were encountered during construction.

[0004] 1. Since the positioning of the four-pile fixed pile stabilization platform determines the positioning of the four pile foundations, the pile stabilization platform needs to have a very high positioning accuracy. Whether it is placed by a crane or positioned by self-floating, the process is very complicated. 2. In near-shore and shallow sea areas, the seabed is generally covered with thick silt. Pile-stabilized platforms that sit on the sea mud by their own weight are prone to tilting and moving under the influence of ocean currents, seawater buoyancy, and unbalanced forces during pile driving, which can lead to the pile foundation not meeting the required accuracy.

[0005] Therefore, it is necessary to provide a marine photovoltaic stabilization pile construction platform with self-leveling and fine-tuning positioning functions. Summary of the Invention

[0006] The purpose of this invention is to provide a marine photovoltaic stabilization platform with self-leveling and fine-tuning positioning functions to solve the problem that existing stabilization platforms are prone to tilting and moving under the action of ocean currents, seawater buoyancy, and unbalanced forces during pile driving, resulting in the pile foundation accuracy not meeting the requirements.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example

[0022] Reference Figure 1-5In this embodiment, a marine photovoltaic (PV) pile stabilization construction platform with self-leveling and fine-tuning positioning functions includes: a platform body, with an end beam 1 at the top for positioning the PV piles, and an opening / closing assembly 104 installed on the end beam 1; and a suction assembly at the bottom of the platform body. The suction assembly includes a suction cylinder 4. This invention achieves continuous multi-pile operation through overall hoisting and displacement. A single platform has four end beams 1, which can simultaneously position four piles, ensuring the relative positional accuracy between piles, reducing the time required for traditional single-pile positioning, and greatly improving construction efficiency.

[0023] Specifically, the platform body includes: an upper crossbeam 2, an upper longitudinal beam 3, a lower crossbeam 5, a lower longitudinal beam 6, a reinforcing beam 7, end beams 1, and suction cylinders 4. There are two upper crossbeams 2, two upper longitudinal beams 3, two lower crossbeams 5, two lower longitudinal beams 6, and two reinforcing beams 7. There are four end beams 1 and four suction cylinders 4. The four suction cylinders 4 are symmetrically arranged. The two upper crossbeams 2 are symmetrically arranged, with both ends of each upper crossbeam 2 connected to the upper ends of two suction cylinders 4. The two upper longitudinal beams 3 are symmetrically arranged between the two upper crossbeams 2, with both ends of each upper longitudinal beam 3 connected to the upper ends of two suction cylinders 4. Every two end beams 1 are symmetrically connected to the two ends of each upper crossbeam 2.

[0024] Two reinforcing beams 7 intersect within the space enclosed by two upper crossbeams 2 and two upper longitudinal beams 3, with each end of the reinforcing beam 7 connected to the upper end of one of the two opposing suction cylinders 4. Two lower crossbeams 5 are symmetrically arranged, with each end of one lower crossbeam 5 connected to the lower end of one of the two suction cylinders 4. Two lower longitudinal beams 6 are symmetrically arranged between the two lower crossbeams 5, with each end of one lower longitudinal beam 6 connected to the lower end of one of the two suction cylinders 4, making the overall structure of the construction platform more stable.

[0025] In this embodiment, the end beam 1 includes a variable cross-section beam segment 101, one end of which is connected to the end of the upper cross beam 2, and the other end is connected to a U-shaped beam segment 102. One end of the cantilever beam segment 106 is hinged to the end of the U-shaped beam segment 102 near the variable cross-section beam segment 101 via an opening and closing assembly 104, and the other end is connected to the end of the U-shaped beam segment 102 away from the variable cross-section beam segment 101 via a pin 107. A boom operating platform 103 is connected to the side of the variable cross-section beam segment 101 near the opening and closing assembly 104. Pile jacks 105 are installed on both the U-shaped beam segment 102 and the cantilever beam segment 106. Platform railings 108 are installed on the variable cross-section beam segment 101, the U-shaped beam segment 102, and the cantilever beam segment 106. The four-way arrangement of pile jacks 105 on a single end beam 1 for coordinated fine-tuning solves the problem of precise pile positioning caused by sea waves, ensuring the accurate position and verticality of the pile. In this embodiment, there are four pile jacks 105. The four pile jacks 105 are arranged circumferentially around the photovoltaic pile body. By coordinating and adjusting the four pile jacks 105, the pile body is positioned in a precise location before the pile driving operation is carried out.

[0026] In this embodiment, the U-shaped beam segment 102, the opening and closing assembly 104, the pile jacking device 105, the cantilever beam segment 106, and the pin shaft 107 form a clamping arm opening and closing mechanism that couples the pile jacking system, realizing the completion of the entire process of "pile hoisting - pile stabilization - vertical adjustment - pile driving" with a single piece of equipment.

[0027] It is worth noting that, in this embodiment, the opening and closing assembly 104 includes: a first adapter plate 10401, which is fixedly connected to the side of the variable cross-section beam segment 101 near the boom operating platform 103; a first lead screw 10403, with a first handwheel 10402 fixedly connected to one end of the first lead screw 10403 near the boom operating platform 103; the end of the first handwheel 10402 away from the first lead screw 10403 is hinged to the first adapter plate 10401 via a bearing; and a first lead screw nut is fitted onto the first lead screw 10403.

[0028] The second transition plate 10405 is fixedly connected to one end of the U-shaped beam segment 102 near the variable cross-section beam segment 101. One end of the first connecting rod 10404 is hinged to the second transition plate 10405, and the other end is hinged to the first lead screw nut. The third transition plate 10407 is fixedly connected to one end of the cantilever beam segment 106 near the variable cross-section beam segment 101. One end of the second connecting rod 10406 ​​is hinged to the third transition plate 10407, and the other end is hinged to the first lead screw nut.

[0029] The user rotates the first handwheel 10402 to drive the first lead screw 10403 to rotate, causing the first lead screw nut to move on the first lead screw 10403, thereby driving the first connecting rod 10404 and the second connecting rod 10406 ​​to move. The second connecting rod 10406 ​​drives the cantilever beam segment 106 to move closer to or away from the U-shaped beam segment 102, causing the opening of the U-shaped beam segment 102 to open or close.

[0030] More specifically, in this embodiment, the pile driver 105 includes an outer tube 10502 detachably connected to the U-shaped beam segment 102 and the cantilever beam segment 106. A lead screw 10503 is partially disposed inside the outer tube 10502, and a second handwheel 10501 is fixedly connected to one end of the second lead screw 10503 after it extends out of the outer tube 10502; a second lead screw nut is fitted onto the second lead screw 10503. One end of the inner tube 10504 is connected to the second lead screw nut, and the other end extends out of the outer tube 10502 and is connected to a roller 10505; the inner tube 10504 is slidably connected to the outer tube 10502.

[0031] In this embodiment, by rotating the second handwheel 10501, the second lead screw nut drives the inner tube 10504 to extend out of the outer tube 10502, and the roller 10505 contacts the pile body. There are four pile jacks 105, which are arranged circumferentially around the photovoltaic pile body. By coordinating and adjusting the four pile jacks 105, the pile body is positioned in a precise position before the pile driving operation is carried out.

[0032] In this embodiment, the suction assembly includes a vacuum pump, a gas supply pipe 401, an air inlet 402, an air outlet 403, and a cylinder 404. The bottom of the gas supply pipe 401 is connected to the cylinder 404, and the top of the gas supply pipe 401 is provided with an air inlet 402 and an air outlet 403. The vacuum pump is connected to the top of the gas supply pipe 401 and is connected to both the air inlet 402 and the air outlet 403. The independent vacuum control system of the suction cylinder enables dynamic leveling of the platform, breaking through the limitation of traditional platforms relying on large engineering vessels for leveling.

[0033] The working process of the offshore photovoltaic stabilization platform with self-leveling and fine-tuning positioning functions in this embodiment is as follows: Before using the platform, press Figure 1 After assembly, the platform is hoisted to the working position using a floating crane and slowly lowered so that the suction cylinder 4 contacts the seabed. Due to the unevenness of the seabed, the platform is tilted at a certain angle. By drawing air through the air outlet 403 to change the vacuum degree of the suction cylinder 4, the depth of the cylinder 404 into the mud is adjusted, thereby adjusting the entire platform to a horizontal state.

[0034] The worker stands on the boom operating platform 103 and opens the cantilever beam segment 106 by turning the first handwheel 10402. The pile can then be placed inside the U-shaped beam segment 102. Turning the first handwheel 10402 closes the cantilever beam segment 106, and a pin 107 is inserted to integrate the cantilever beam segment 106 with the U-shaped beam segment 102. The worker then climbs onto the end beam 1 and turns the second handwheel 10501 to extend the inner tube 10504, allowing the roller 10505 to contact the pile. Through the coordinated adjustment of the four pile jacks 105, the pile is positioned precisely before driving.

[0035] After the four piles are driven in accordance with the above process, the inner tubes 10504 of each pile driver 105 are retracted, the pins 107 are pulled out, and the first handwheel 10402 is turned to open the cantilever beam section 106. Air is pumped into the air supply pipe 401 through the air inlet 402 to separate the cylinder 404 from the seabed, and then the platform is lifted off the working position by a floating crane to complete the installation.
