Detailed Description of the Preferred Embodiment
[0017] The following further describes the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.
[0018] Embodiment of the present utility model: A water surface photovoltaic anchoring system with adaptive water level change includes a photovoltaic floating body 6, a water surface photovoltaic array 2 is arranged on the surface of the photovoltaic floating body 6, the edge of the photovoltaic floating body 6 is connected to an anchor floating body 4 through a high-strength elastic mooring cable 5, the anchor floating body 4 is movably sleeved on an anchor steel pile 3, and the anchor steel pile 3 is vertically fixed in the water body.
[0019] During use, the combined value of environmental loads is calculated according to the layout design of the floating PV array 2. The number of required anchoring steel piles 3 is calculated based on the combined value of environmental loads and the characteristic value of the horizontal bearing capacity of a single anchoring steel pile 3. The anchoring steel piles 3 are evenly arranged on the plane. The PV floating body 6 is connected to the anchoring floating body 4 sleeved on the anchoring steel pile 3 through high-strength elastic mooring cables 5 to form the entire mooring structure 1. As the water level changes, the entire mooring structure 1 will also float up and down to adapt to the change of the water level. However, in the horizontal direction, due to the limitation of the high-strength elastic mooring cables 5, the anchoring floating body 4 and the anchoring steel pile 3, the horizontal position is relatively fixed, which better ensures the stable operation of the PV system.
[0020] The PV floating body 6 is formed by connecting multiple PV floating body sub-units 9 to form a whole, which is convenient for assembly, disassembly, replacement and transportation.
[0021] The PV floating body sub-unit 9 is of a rectangular structure, and a plurality of ear plates 10 are arranged on each side thereof. Bolt insertion holes are provided on the ear plates 10. After the ear plates 10 of two adjacent PV floating body sub-units 9 overlap, they are fixedly connected together by bolts. The ear plates 10 can be set as upper and lower ear plate structures, that is, the left side is the upper ear plate, then the right side is the lower ear plate, the front side is the upper ear plate, then the rear side is the lower ear plate. The upper and lower ear plate structures ensure that when two adjacent PV floating body sub-units 9 are in contact temporarily, the upper ear plate and the lower ear plate overlap in space but do not touch, so as to facilitate the fixation of two adjacent PV floating body sub-units 9 by bolts.
[0022] One side of the PV floating body sub-unit 9 is also provided with a hanging buckle 11; a plurality of hanging buckles 11 are also provided on the anchoring floating body 4. The two ends of the high-strength elastic mooring cable 5 are respectively connected to the hanging buckles 11 on the PV floating body sub-unit 9 and the anchoring floating body 4. It is convenient to connect the high-strength elastic mooring cable 5 through the hanging buckle 11. A plurality of hanging buckles 11 are provided on the anchoring floating body 4. When there are multiple floating PV anchoring systems on the water surface, the high-strength elastic mooring cables 5 of other floating PV anchoring systems can also be connected to other hanging buckles 11 of this anchoring floating body 4.
[0023] The PV floating body 6 is of a rectangular structure, and at least 4 groups of high-strength elastic mooring cables 5 are provided, which are respectively arranged at the four corners of the PV floating body 6 and are mutually tied to make the plane position of the floating PV array 2 more stable.
[0024] The high-strength elastic mooring cable 5 is a stainless steel multi-strand steel wire rope, which meets the requirements of strength and corrosion resistance.
[0025] A retaining cover 12 is fixed to the top of the anchored steel pile 3 to form an anti-detachment limiting device. The size of the retaining cover 12 is larger than the aperture of the insertion hole on the anchored floating body 4 through which the anchored steel pile 3 passes, so as to prevent the anchored floating body 4 from disengaging after the water level rises above the anchored steel pile 3. The designed height of the anchored steel pile 3 should be not less than 500 mm higher than the highest water level with a 25-year return period. The characteristic value of the horizontal bearing capacity of a single anchored steel pile 3 should be determined through a single-pile horizontal static load test.
[0026] The floating body materials of the photovoltaic floating body sub-unit 9 and the anchored floating body 4 are made of high-strength plastics, which can ensure strength while meeting the anti-corrosion performance.
