As shown in fig. 1, 2 and 3, the present embodiment is mainly divided into three parts of an onshore assembly area, a sewer area and an onshore assembly area, and the following procedure can be followed during implementation: foundation lofting, soil and stone compaction backfilling and concrete surface layer pouring; and (3) construction of a water draining area: measuring lofting, soil and stone compaction backfilling, gravel slope protection, facing concrete, a chute concrete base, a chute steel support, a chute paving bamboo plywood and high-strength waterproof cloth on the upper part of the bamboo plywood; construction of an assembly area on water: construction of a steel frame of a floating platform on water, fastening of a pontoon, steel frame, laying of a bamboo plywood, and laying of high-strength waterproof cloth on the upper part of the bamboo plywood.

As shown in fig. 1, the chute type assembling platform applicable to the floating type photovoltaic power station provided by the embodiment mainly comprises an onshore assembling area 1, a sewer area 2 and an onshore assembling area 3.

The shore assembly area 1 mainly performs single floating body/assembly work, the area is completed by backfilling soil and stones, and the compactness is not less than 90%. Providing a smooth and spacious working surface for the float/assembly, and casting a concrete surface layer 4 on the upper part of the backfill area. The photovoltaic project is generally shorter in construction period, in order to meet the annual construction requirement, a semi-closed workshop 5 is designed in an onshore assembly area 1, the semi-closed workshop 5 comprises a plurality of workshop supporting pieces and a roof, the workshop supporting pieces are combined into a frame structure and are fixed on a concrete surface layer 4, and a color steel tile roof is fixedly paved on the top of the frame structure.

The sewage area 2 is provided with gravel protection slopes 7 on the water-facing slope surface in order to prevent soil slope erosion caused by water level fluctuation and waves and the like from causing slope instability on the basis of soil and stone backfill. As shown in fig. 1 and 2, a plurality of groups of sliding grooves 18 are arranged on the water-facing slope side by side, each group of sliding grooves 18 is composed of a plurality of segments 18.1 which are connected in sequence, each segment 18.1 is supported on the water-facing slope through a supporting leg 17, and the supporting legs 17 and the segments 18.1 are connected through a detachable structure. The gravel slope 7 below the chute 18 needs to be poured with a concrete facing 8, and the concrete facing 8 is used as a fixed foundation of the supporting legs 17, so that not only can the anti-scouring capability of the gravel slope 7 be improved, but also the foundation strength of the chute can be improved. The design width of the chute 18 will depend strictly on the single width of the float 14, with the recommended chute width being 10-15cm greater than the single width of the float 14, and an excessive chute width will lose the guiding effect on the float/assembly sliding down process; the height of the chute is slightly less than 5cm of the maximum height of the float 14, preventing the chute from being too high on both sides and cutting the assembly 15 during the float/assembly sliding down. To prevent sliding of the chute 18 with the foundation, the concrete foundation 6 of the leg 17 is poured on the ground in the slope top or on-shore assembly area.

As shown in fig. 3, each section 18.1 includes a groove-shaped framework 20 formed by section steel, a base plate 11 laid at the bottom of the groove-shaped framework 20, and a high-strength waterproof cloth 12 (the surface of which is smooth and the wall thickness of which is not easy to puncture) laid on the upper surface of the base plate 11, wherein the high-strength waterproof cloth 12 can avoid scratches caused by friction between the base plate 11 and the bottom of the floating body, the base plate 11 can be made of different plates as required, and a bamboo plywood is recommended. In order to effectively maintain the overall stability of the runner 18, expansion bolts 9 serving as reinforcing members are implanted into the concrete facing 8, and the support legs 17 can be effectively fixed by the expansion bolts 9. As shown in fig. 1, each group of sliding grooves 18 is divided into at least three segments 18.1, the segments 18.1 are mutually connected, and a detachable buckle 13 is arranged between the segments 18.1 and the supporting legs 17. When the water level rises, the buckle 13 of the lowest section is removed to remove the subsection 18.1, the subsection of the next section is still located on the water splicing area, and the water inlet angle is basically unchanged; on the contrary, after the water level is lowered, a section of segment 18.1 is added through the buckle 13, and the water draining area 2 is smoothly extended to the water assembling area 3.

The water assembly area 3 comprises a platform frame 10, a pavement plate paved on the top of the platform frame 10 and a pontoon 16 fixed on the bottom of the platform frame 10, wherein two sides of the platform frame 10 are moored to the shore through anchor ropes. The length of the water splicing area 3 is generally closely related to the number of components dragged into the permanent anchoring array, so that the splicing times of the permanent anchoring square array are reduced, the length of the water splicing area is equal to that of the sub square array, the length of the sub square array is L, and the permanent anchoring square array is an integer multiple n (n is the value of 1, 2 and 3). The width direction of the water assembly platform is larger than 5 times of the width of the assembly, at least 3 rows of assemblies are assembled, and 2 rows of assemblies are to be pushed into a water area.

The main construction materials of the water splicing area 3 are as follows: profile steel, pontoons 16, bamboo plywood, and high-strength waterproof cloth 12. Firstly, the section steel is welded into the platform frame 10, then the pontoons 16 are fixed in the platform frame 10 at equal intervals, the section steel can be pushed into a water area after the whole body is reinforced, and the whole water assembly area 3 provides buoyancy by the pontoons 16. The deck frame 10 has a deck on its top surface, which recommends the use of a good quality bamboo plywood, avoiding the deformation of the bamboo plywood due to long-term insolation, thereby increasing the risk of cutting the floating body or tripping a worker. The high-strength waterproof cloth 12 is paved on the upper part of the bamboo plywood to prevent scratches caused by direct long-term contact between the bottom of the floating body and the bamboo plywood, so that the service life of the floating body is prevented from being influenced.

In this embodiment, the inclined water inlet connection section 19 is added at the front end of the platform frame 10, mainly to provide better water inlet conditions for the assembled floating bodies/components, and the water inlet angle is optimized by combining the bending limit angle which can be born by the floating body holding lugs, so that the assembled floating bodies/components in rows can be smoothly and efficiently pushed into the water in order.

In this embodiment, the launch area 2 is a key channel connecting the onshore assembly area 1 and the onshore assembly area 3, the uppermost segment 18.1 of the chute 18 extends to the onshore assembly area 1, and the lowermost segment extends to the onshore assembly area 3. After the floating body 14 and the component 15 are assembled in the semi-closed workshop 5 of the onshore assembly area 1, the angle of the sliding chute 18 can be properly adjusted through the buckle 13, so that the floating body 14 and the component 15 can be ensured to stably and reliably slide from the onshore assembly area 1 to the onshore assembly area 3, and after the onshore assembly area 3 is assembled, the floating body is pushed into water from one side of the water inlet connecting section 19.

The foregoing description is only of the preferred embodiments of the present utility model, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
