Description

Technical Field

[0001] The utility model relates to the technical field of pile stabilizing platforms, in particular to an offshore photovoltaic pile stabilizing platform. Background Technique

[0002] At the present stage, when installing offshore photovoltaic panels, a truss structure supported by four-foot fulcrums is mostly adopted, that is, during the installation of the truss of the photovoltaic panel, four steel pipe piles need to be driven vertically into the construction water area to support the truss of the photovoltaic panel. Therefore, the verticality of each steel pipe pile directly affects the installation quality of the offshore photovoltaic platform;

[0003] Chinese Patent "202410510374.1" discloses an "intelligent leveling device and leveling method for the construction of an offshore photovoltaic pile stabilizing platform", which discloses the leveling of the pile stabilizing platform, but there is no detailed plan on how to carry out limit during the steel pipe pile driving construction. At the same time, when the pile stabilizing platform moves to the next construction point, equipment such as a crane ship is still needed for transportation, which takes a long time and slows down the construction progress. Content of the Utility Model

[0004] The purpose of the utility model is to provide an offshore photovoltaic pile stabilizing platform which can preliminarily position the foundation pile by setting multiple layers of hoop bodies, facilitate the subsequent construction of the foundation pile, and at the same time set air bags to realize the floating of the pile stabilizing platform, facilitating the transportation of the pile stabilizing platform on the sea surface.

[0005] The utility model is realized by the following measures:

[0006] An offshore photovoltaic pile stabilizing platform, including an upper and lower double-layer frame, four legs are arranged at the four corners of the double-layer frame, and the double-layer frame and the four legs are connected to form a pile stabilizing platform. It is characterized in that a plurality of support steel beams are arranged on the side of the leg near the top, and a hoop body is arranged at the end of the support steel beam;

[0007] The hoop body includes two semi-circular hoops, a support main shaft is arranged at the end of the support steel beam, the semi-circular hoops are arranged on the support main shaft, and a rotary oil cylinder for driving the semi-circular hoops to open and close is arranged between the two semi-circular hoops and the support main shaft;

[0008] Preferably, the uppermost hoop body is higher than the double-layer frame;

[0009] A steel platform is welded on the outer side of the semi-circular hoop. In order to facilitate subsequent maintenance and other operations, to ensure that when the hoop is in the open state, the steel platforms of the two semi-circular hoops do not conflict with each other;

[0010] One end of the rotary oil cylinder is hinged to the support main shaft, and the other end of the rotary oil cylinder is hinged to the semi-circular hoop of the hoop. When controlling the telescopic movement of the rotary oil cylinder, the opening and closing action of the hoop body can be realized;

[0011] A pair of mounting brackets are provided on the semi-encircling hoop. A pile diameter hydraulic adjusting rod is provided on the mounting bracket. A guide wheel is provided at the end of the pile diameter hydraulic adjusting rod. A pile body guide plate is provided on the pile diameter hydraulic adjusting rod above the guide wheel.

[0019] The closing component includes a number of limiting plates provided at the ends of the two semi-encircling hoops on both sides. The number of limiting plates is distributed up and down in a staggered manner. A number of limiting plates are provided with corresponding limiting holes. A limiting pin is arranged in the limiting holes. When the hoop is closed, the centers of the limiting holes on the number of limiting plates coincide. At this time, the limiting pin is inserted to ensure the reliability of the closing.

[0020] The four pile diameter hydraulic adjusting rods on the hoop body are evenly distributed. The fixed pile body system of a single hoop body is mainly composed of four pile diameter control hydraulic adjusting rods, a guide plate, and a rubber pulley. The four pile diameter control hydraulic adjusting rods are symmetrically arranged and realize synchronous telescoping through control. The thrust of the pile diameter control hydraulic adjusting rods is used to realize the function of fixing the pile body.

The pile body guiding plate is connected to the hydraulic regulating rod for pile diameter to achieve the function of synchronous expansion and contraction.

[0023] During construction, the pile stabilizing platform is transported to the construction sea area, lifted to the water by a crane ship, and placed on the seabed. During pile foundation construction, first, four foundation piles are sequentially inserted into the four hoop main bodies. The uppermost hoop main body is used to limit and guide the foundation piles. Then, the foundation piles pass through the lower hoop main bodies and are inserted into the seabed, and then pile driving construction is carried out.

[0024] Before pile foundation construction, several hoop main bodies are closed, and a limit pin is inserted into the uppermost hoop main body to ensure the reliability of the closure of the uppermost hoop main body. Then, four hydraulic regulating rods for pile diameter control expand and contract the guiding wheels according to the size of the foundation piles, and the foundation piles are inserted between several guiding wheels.

[0025] After construction is completed, the hydraulic regulating rods for pile diameter control contract and reset, the hoop body opens, the platform is lifted by a crane ship to be separated from the pile body after construction, and then placed on the sea surface. The air inflation pump is controlled to inflate the air inflation balloon, and the pile stabilizing platform floats by buoyancy. After being pulled to the construction sea area by a crane ship, the air inflation pump is controlled to deflate the air inflation balloon, and the pile stabilizing platform falls under the influence of gravity. The position of the platform is adjusted by lifting it with a crane ship and then it falls to the construction area, and pile driving construction is carried out again.

[0026] The beneficial effects of the present utility model are as follows: By setting multiple hoop main bodies, preliminary positioning of the foundation piles can be achieved, facilitating subsequent construction of the foundation piles. At the same time, by setting air bags, the pile stabilizing platform can float, facilitating the transportation of the pile stabilizing platform on the sea surface. Description of the Drawings
