Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a marine floating photovoltaic energy dissipation and vibration reduction device. Background Technology

[0002] Existing floating photovoltaic units and mooring systems are mainly used in inland lakes. The main reason is that the waves in inland waters are smaller and the relative motion is also smaller. The floating system is not greatly affected by external loads. Therefore, the connection structure between floating units is simple (allowing the water surface wave height not to exceed 1m). However, in the marine environment, the wind and waves are high and the wind and wave conditions in the marine environment are much greater than those in inland lakes, and the superimposed tidal influence is greater.

[0003] Existing floating photovoltaic structures, being on the sea surface, cannot withstand the harsh winds and currents of the ocean and lack shock-absorbing devices to resist these forces, thus affecting the lifespan of the photovoltaic devices. Furthermore, the special installation environment on the floating platform makes it difficult to adjust the photovoltaic panels after installation, leading to reduced installation efficiency. To address these issues, we propose a floating photovoltaic energy dissipation and shock absorption device. Utility Model Content

[0004] The purpose of this utility model is to provide a floating photovoltaic energy dissipation and vibration reduction device for the sea, in order to solve the problem mentioned in the background art of the lack of vibration reduction devices that can resist wind and waves at sea, which leads to reduced installation efficiency due to the special nature of the installation environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floating photovoltaic energy dissipation and vibration reduction device for marine applications, comprising a fixed connecting cable, a square floating platform, an annular floating platform, an energy dissipation plate, a connecting screw, and a connecting stud. The square floating platform has a first connecting lug fixedly connected to its four outer corners, with a first connecting hole at the top of each lug. The annular floating platform has a second connecting lug fixedly connected to its four outer corners, with a second connecting hole at the top of each lug. The first connecting lug is located at the top of the second connecting lug. The energy dissipation plate has mounting holes. The connecting screw is inserted between the inner cavities of the first connecting hole, the second connecting hole, and the mounting hole. The energy dissipation plates are arranged sequentially from top to bottom, with through holes evenly distributed at the top. Fixing bolts are provided at the top and bottom of the energy dissipation plates, located outside the mounting holes, and these fixing bolts are screwed to the connecting screw.

[0006] Preferably, the right end of the fixed connecting cable is fixedly connected to an outer floating plate, and the outer floating plates are arranged sequentially from front to back. The front and rear sides of the right side wall of the outer floating plate are fixedly connected to fixed connecting ears. The fixed connecting ears are located below the first connecting ear on the left side, and a fixed connecting hole is opened at the top of the fixed connecting ear. The connecting screw on the left side is inserted between the inner cavity of the fixed connecting hole and the first connecting hole.

[0007] Preferably, an upper bolt is screwed onto the outer side wall of the connecting screw and above the first connecting lug, and a lower bolt is screwed onto the outer side wall of the connecting screw and below the second connecting lug. Anti-slip pads are provided at the bottom of the upper bolt and the top of the lower bolt.

[0008] Preferably, the connecting stud is screwed to the top of the connecting rod, the connecting stud is located at the four corners of the annular floating platform, and a locking bolt is screwed to the outer wall of the connecting rod and below the connecting stud.

[0009] Preferably, a mounting plate is fixedly connected to the top of the connecting stud, an annular base is fixedly connected between the outer walls of the mounting plate, and a movable block is slidably connected to the inner cavity of the annular base.

[0010] Preferably, mounting rods are placed on the front and rear sides of the top of the annular base, and adjustment holes are opened at the bottom of the mounting rods. The adjustment holes are arranged sequentially from left to right. An adjustment screw is slidably connected to the inner cavity of the adjustment hole. The bottom end of the adjustment screw extends into the inner cavity of the annular base, and the bottom end of the adjustment screw is screwed to the moving block.

[0011] Preferably, connecting rods are fixedly connected to the top left and right sides of the mounting rod, and photovoltaic panels are fixedly connected between the top ends of the connecting rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This floating photovoltaic vibration damping device uses second connecting lugs around the annular floating platform and first connecting lugs around the square floating platform to connect connecting screws through first and second connecting holes. The square and annular floating platforms are arranged in an alternating pattern to form a whole. Multiple energy dissipation plates are installed on the underside of the connecting screws, and the energy dissipation plates have evenly distributed through holes. Through the overlapping of multiple energy dissipation plates, the wave-like flowing sea waves come into contact with the energy dissipation plates and dissipate the energy of the sea waves through the through holes. This effectively resists sea waves and reduces the dynamic response on the wave-facing side of the floating photovoltaic system, effectively improving the floating photovoltaic system's ability to resist sea waves and further extending the service life of the floating photovoltaic structure.

[0014] 2. This floating photovoltaic vibration damping device for marine applications involves mounting photovoltaic panels onto an installation rod via connecting rods to form an integrated installation structure. The installation rod is then placed on a ring-shaped base. An adjusting screw passes through an adjusting hole and is screwed into a movable block inside the ring-shaped base. The device rotates and adjusts according to the installation direction of the photovoltaic panels, which in turn moves the movable block within the ring-shaped base. After adjustment, the adjusting screw is tightened for fixation. This allows for overall rotational direction adjustment after the photovoltaic device is installed, simplifying installation and improving efficiency. Attached Figure Description
