step 2) connecting a plurality of buoys 2 to form a support system 1, wherein the floating photovoltaic power station is arranged on the support system 1;
step 3) placing the supporting system 1 in a water area surrounded by the anchor piles 3, and then connecting the connecting ropes 5 in each rope assembly with the supporting system 1 at the corresponding position;
and 4) completing installation of the anchoring structure of the floating photovoltaic power station.
Example two:
the difference from the first embodiment is that, as shown in fig. 4 and fig. 5, in the present embodiment, an intermediate connection assembly is further included, the intermediate connection assembly is disposed at a corresponding position of each anchor pile 3, the intermediate connection assembly includes a connection block 9, one side of the connection block 9 is connected with the anchor pile 3 at the corresponding position through a cable assembly, one side of the connection block 9, which is far away from the connection cable 5 assembly, is provided with a connection protrusion 10 facing the support system 1, one side of the connection protrusion 10, which faces the support system 1, is sequentially provided with a first installation hole 15 and a first installation groove 14, which face the other side of the connection protrusion 10 and are communicated with each other, the aperture of the first installation hole 15 is smaller than that of the first installation groove 14, a limit block 12 is further slidably connected in the first installation groove 14, the size of the limit block 12 in the aperture direction of the first installation hole 15 is larger than that of the first installation hole 15, one side of the limit block 12, the limiting block 12 is provided with a limiting bump 13 protruding out of the first mounting hole 15 and fixedly connected with the buoy 2 on the support system 1 at a corresponding position, far away from the side where the limiting block 12 is connected with the first spring 11, in an initial state, the first spring 11 is in a free extension state, and the distance between the limiting block 12 and the first mounting hole 15 is greater than a set distance.
Thus, by arranging the intermediate connection assembly, the rope assembly is connected with the buoy 2 in the support system 1 by using the intermediate connection assembly, when the support system 1 shakes under the action of wind power or water flow, because the limit block 12 is slidably connected in the first installation groove 14, the buoy 2 in the support system 1 can drive the limit block 12 to slide in the first installation groove 14, meanwhile, because the support system 1 is integrally composed of a plurality of buoys 2, and the weight and the size of the connection block 9 are smaller than those of the whole support system 1, when external force acts on the support system 1 and the connection block 9, the displacement of the connection block 9 is necessarily larger than that of the support system 1, at this time, the first spring 11 in the first installation groove 14 is compressed by the connection block 9, and the first spring 11 generates an elastic force for driving the connection block 9 to return to the initial position after being compressed, under the effect of this elasticity, connecting block 9 will have the trend of getting back to the initial position, through the suitable selection to first spring 11 elasticity, can make first spring 11 be greater than the effort of wind-force and rivers to connecting block 9 to the elasticity that connecting block 9 produced, make connecting block 9 have the trend of keeping at initial condition all the time from this, just so avoided under the exogenic action connecting block 9 displacement too big cause with connect between rope 5 the junction and the damage of rope subassembly, simultaneously, because be the fixed connection of rigid structure between spacing lug 13 and the flotation pontoon 2, the damage also does not easily appear in spacing lug 13 and flotation pontoon 2 junction.
