Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic technology, specifically a marine photovoltaic pile frame. Background Technology

[0002] Offshore photovoltaics (PV) refers to a new type of renewable energy technology that deploys photovoltaic power generation systems on the ocean or other bodies of water to produce electricity using solar energy. Compared with traditional terrestrial PV systems, offshore PV systems use floating or fixed photovoltaic arrays installed on the sea surface or floating platforms, making full use of vast water spaces to generate solar power.

[0003] When installing offshore photovoltaic (PV) systems, foundation supports need to be installed in the water. Fixed supports typically require piling, and offshore PV piles are the structural supports that hold the offshore PV power generation system in place. These piles are usually designed to be firmly anchored in the seabed soil to support the PV modules installed on them. The main function of offshore PV piles is to ensure the stability and safety of the PV power generation system by anchoring them in the seabed soil, resisting the effects of marine environmental factors such as waves, wind, and tides.

[0004] Existing offshore photovoltaic (PV) piles are simply inserted into the seabed soil before being connected by a support frame. However, the stability of a single bearing point is insufficient. If the seabed soil is uneven or contains soft sediments, or if strong winds or waves occur, traditional piles are easily affected by lateral forces, and the piles are prone to tilting or displacement. To solve the above-mentioned problems, an offshore PV pile frame is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a marine photovoltaic pile frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine photovoltaic pile frame, comprising a pile body;

[0007] The outer wall of the pile is fixedly fitted with a cover ring for compacting seabed soil and silt. A rotating ring is rotatably installed at the lower end of the cover ring, and a pin for inserting into the seabed soil is fixedly connected at the lower end of the rotating ring. Multiple pins are evenly arranged in a ring array with the central axis of the pile as the center.

[0008] The lower end of the pile is used to spirally insert into the seabed soil. Multiple pins are inserted into the seabed soil as the pile descends to stabilize it and prevent it from tilting.

[0009] As a preferred technical solution of this utility model, the lower side of the outer wall of the pile body is provided with threads for screwing into the seabed soil.

[0010] As a preferred technical solution of this utility model, the upper end of the cover ring is provided with multiple discharge holes, and a filter screen for discharging seawater is installed in the discharge holes.

[0011] As a preferred technical solution of this utility model, the filter screen is made of woven metal wires.

[0012] As a preferred technical solution of this utility model, the upper end of the rotating ring is provided with multiple rotating grooves, and rollers that facilitate the rotation of the rotating ring are rotatably installed in the rotating grooves.

[0013] As a preferred technical solution of this utility model, multiple rollers are evenly arranged in a ring array with the central axis of the pile as the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the lower end of the pile is spirally inserted into the seabed soil. Multiple pins are inserted into the seabed soil as the pile descends. By increasing the bearing points of the pile, the pile is stabilized and tilting is prevented. This solves the problem that existing offshore photovoltaic piles, which are simply inserted into the seabed soil before being connected by a support frame, have insufficient stability due to a single bearing point and are prone to tilting or displacement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment provides a marine photovoltaic (PV) pile frame, including a pile body 1. The pile body 1 is based on the PV foundation piles produced by Hebei Keyong Metal Products Co., Ltd. A thread 11 is provided on the lower side of the outer wall of the pile body 1. The pile body 1 is driven into the seabed soil by a marine piling machine. The thread 11 increases the contact area and friction between the pile body 1 and the seabed soil. Through the rotation of the thread 11, the pile body 1 can better "bite" the soil when inserted into the seabed, enhancing its pull-out resistance and overturning resistance. This, to a certain extent, prevents the pile body 1 from tilting or shifting under the action of waves or strong winds. Simultaneously, the thread 11 also helps the pile body 1 smoothly "cut" into the seabed soil when inserted, preventing the pile body 1 from failing to accurately insert into the predetermined position due to slippage or deviation. The thread 11 acts like a "spiral cutting edge," helping to maintain the directional stability of the pile body 1, allowing it to enter the seabed soil at a more precise angle.

[0024] However, most existing subsea piles 1 are inserted into the seabed soil in a single way. The single bearing point is not stable enough, has insufficient pull-out resistance, and is not strong enough to resist wind, waves and tides. In order to increase the stability of the pile 1, multiple pins 31 are rotatably installed on the outer side wall of the pile 1.

[0025] Specifically, such as Figure 2As shown, a cover ring 2 is fitted onto the outer wall of the pile body 1. Multiple discharge holes are provided at the upper end of the cover ring 2, and filter screens 21 are installed inside these holes. The filter screens 21 are made of woven metal wire, preferably stainless steel, but not limited to stainless steel; any metal material resistant to corrosion and seawater erosion is acceptable. During the insertion of the pile body 1 into the seabed soil, the cover ring 2 descends synchronously. Upon contact with the seabed soil, the cover ring 2 compacts the soil, while seawater and silt with high moisture content are discharged through the filter screen 21. After the pile body 1 is installed, the cover ring 2 and filter screen 21 compact the soil in the installation area. The design of the cover ring 2 and the pile body 1 effectively prevents excessive lateral displacement of the pile body 1 during insertion, reducing uneven stress on the pile body 1, thereby increasing the stability and pull-out resistance of the pile body 1 and ensuring the long-term stable operation of the photovoltaic system. Through this design, the connection between the pile body 1 and the seabed soil is tighter, and the soil around the pile body 1 is more compacted, thus improving the pile body 1's overturning resistance and seismic resistance. In addition, the synergistic effect of the cover ring 2 and the filter screen 21 can effectively prevent soil loosening or erosion caused by seawater flow, especially under the action of tides and waves, ensuring that the pile body 1 can maintain its structural integrity and stability in a dynamic environment.

[0026] like Figure 2 and Figure 4 As shown, the lower end of the cover ring 2 has an annular groove, within which a rotating ring 3 is rotatably installed. Multiple pins 31 are evenly connected in a circular array around the central axis of the pile body 1 at the lower end of the rotating ring 3. When the cover ring 2 compacts the soil surrounding the pile body 1, the pins 31 are simultaneously inserted into the seabed soil. The pins 31 increase the bearing capacity of the pile body 1, further stabilizing it. The cooperation between the rotating ring 3 and the cover ring 2 ensures the precise position and depth of the pins 31, allowing them to function continuously throughout the installation process. The presence of the rotating ring 3 prevents the pins 31 from rotating synchronously when the pile body 1 is driven into the seabed. Upon contact with the seabed soil, the pins 31 are resisted and stop rotating, then descend with the pile body 1 into the seabed soil. The design of the pins 31 effectively enhances the bearing capacity of the pile body 1, especially in cases where the seabed soil is relatively soft or loose. It increases the contact area between the pile body 1 and the soil, creating more stress points and reducing the possibility of tilting or displacement of the pile body 1. By using the insertion pins 31, the stability of the pile body 1 on the seabed is significantly enhanced, enabling it to more firmly resist the effects of tides, waves, and ocean currents in the marine environment, and preventing damage to the photovoltaic system due to external forces. The depth and distribution of the insertion pins 31 can be adjusted according to different seabed geological conditions, adapting to complex environments such as soft soil and silt, ensuring that the photovoltaic pile maintains stability under various seabed conditions.

[0027] like Figure 3 and Figure 5As shown, to stabilize the rotation of the rotating ring 3, multiple rotating grooves are provided at the upper end of the rotating ring 3. Rollers 32 are rotatably installed inside the rotating grooves, with parts of the rollers 32 protruding from the upper end of the rotating ring 3. Specifically, the multiple rotating grooves and rollers 32 are evenly arranged in a circular array with the central axis of the pile body 1 as the center. After the pin 31 contacts the seabed soil, it can drive the rotating ring 3 to move slightly upward, with a movement height of less than 3mm. This allows the upper end of the rollers 32 to contact the top surface of the inner groove of the cover ring 2. When the rotating ring 3 rotates, the rollers 32 will rotate, thereby effectively reducing the friction between the rotating ring 3 and the cover ring 2, making the rotation of the rotating ring 3 more flexible, smoother, and more fluid.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
