Description

Technical Field

[0001] The present invention relates to the field of photovoltaic assembly technology, and in particular to an assembled offshore photovoltaic floating platform and a photovoltaic power generation system. Background Art

[0002] The assembled offshore photovoltaic floating platform is a modularly designed marine energy facility. Through the rapid assembly of prefabricated components, the photovoltaic power generation system can be stably floated and efficiently operated in the marine environment. By combining the photovoltaic power generation system with marine engineering, it breaks through the limitations of land resources and becomes a key technology to promote the use of clean energy in the deep sea.

[0003] Publication number CN114987710B provides an assembled offshore photovoltaic floating platform, which includes several modular photovoltaic platform units, a central platform, photovoltaic modules and mooring anchoring devices; the modular photovoltaic platform units are fan-shaped in geometry and are connected in a circular manner to form an offshore photovoltaic floating platform; the modular photovoltaic platform units include a truss platform, a platform connector and a buoy; the platform connector is arranged on the connection side of the truss platform for connecting adjacent modular units; the buoy is located at the lower end of the truss platform to provide buoyancy for the modular photovoltaic platform units.

[0004] However, when the above-mentioned assembled offshore photovoltaic floating platform is in use, the two truss platforms need to be connected through a platform connector. At this time, the two platform connectors need to be brought close and aligned, but the two truss platforms float on the water, making it difficult to quickly connect the two connectors. Summary of the Invention

[0005] The purpose of the present invention is to provide an assembled offshore photovoltaic floating platform and a photovoltaic power generation system to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] In one aspect, an assembled offshore photovoltaic floating platform is provided, comprising:

[0008] A floating support, comprising a truss platform and a buoy arranged below the truss platform;

[0009] A connecting assembly, the connecting assembly comprising a hook and clamp mechanism provided on the truss platform, and a plug-in mechanism provided on the truss platform and located on an opposite side of the hook and clamp mechanism;

[0010] The docking assembly includes a docking box arranged on the truss platform, a guide bracket arranged in the docking box, a fixed bracket arranged on the opposite side of the guide bracket, a locking mechanism arranged on the guide bracket, a release mechanism arranged on the docking box and connected to the locking mechanism, a docking strip arranged on the fixed bracket, and an anti-loosening hole arranged on the docking strip. When the docking strip is inserted into the guide bracket on the adjacent floating bracket, the docking strip is used to pull the plug-in mechanism toward the hook and clamp mechanism. When the docking strip moves, the locking mechanism is inserted into the release hole in sequence to prevent the release strip from moving in the opposite direction until the plug-in mechanism contacts the hook and clamp mechanism, so that the hook and clamp mechanism is inserted into the plug-in mechanism to connect the two floating platforms.

[0011] Preferably, photovoltaic panels are provided on the truss platform, and fences are provided at the edges of the truss platform.

[0012] Preferably, the hook and clamp mechanism includes a hook box arranged on the truss platform, a movable hook rod arranged in the hook box, a hook groove and a rotating groove opened on the hook box, a hook block arranged in the hook groove, a limit block arranged on the hook box, a connecting hook rod arranged in the rotating groove and passing through the limit block, a spring connecting plate arranged on the truss platform, and a downward pressure spring arranged on the spring connecting plate and connected to the hook block.

[0013] Preferably, the plug-in mechanism includes a connecting tube provided on the truss platform and a connecting groove provided on the connecting tube.

[0014] Preferably, when the connecting tube pushes against the movable hook rod, causing the movable hook rod to slide through the hook block and hook with the hook block, the movable hook rod simultaneously pushes the connecting hook rod to rotate, causing the connecting hook rod to be inserted into the connecting groove, thereby connecting the two truss platforms, and the downward pressure spring is used to press down the hook block so that the hook block remains hooked with the movable hook rod, and the limit block is used to limit the opening angle of the connecting hook rod.

[0015] Preferably, the guide bracket includes a guide base plate arranged in the docking box and a guide wheel arranged on the guide base plate; the fixed bracket includes a fixed base plate arranged in the docking box and a slot provided on the fixed base plate; an upper pull groove connected to the docking box is provided on the truss platform; and an insert plate is provided on the docking strip.

[0017] Preferably, the release mechanism includes a pull-down rod provided on the docking box, a connecting rod provided on the pull-down rod and connected to the docking base plate, and a positioning spring provided on the pull-down rod and connected to the truss platform.

[0018] Preferably, after the plug plate is inserted into the slot, the docking strip is arranged along the guide wheel and extends from the upper pull groove. After pulling the docking strip, the two truss platforms are driven closer together. The moving docking strip drives the rotating lock rod to rotate, so that when the anti-loosening hole passes through the rotating lock rod, the reset spring pushes the sliding lock rod to reset and insert it into the release hole. The lower pull rod is driven to move the docking base plate downward, driving the rotating lock rod to move out of the release hole, so that the docking strip can move in the opposite direction, so that the two truss platforms are separated.

[0019] On the other hand, a photovoltaic power generation system is also provided, comprising any of the assembled offshore photovoltaic floating platforms described above.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention adopts the arrangement of a hooking mechanism, a plug-in mechanism and a docking strip, and can quickly align and connect by pulling the docking strip so that the plug-in mechanism contacts the docking strip. The arrangement of a locking mechanism prevents the docking strip from loosening and prevents the two trusses from moving away. The arrangement of a releasing mechanism releases the fixation of the docking strip and allows the two trusses to move away. BRIEF DESCRIPTION OF THE DRAWINGS
