[0042] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the embodiment of the utility model provides an offshore floating photovoltaic floating body, comprising: a floating body 1, a filler 2 and a pre-buried pipe 3, wherein the floating body 1 has a hollow structure 11 inside; the top side wall of the floating body 1 is provided with a first connection hole 12 and a second connection hole 13 for connecting with an adjacent photovoltaic body, the axis of the first connection hole 12 and the axis of the second connection hole 13 are perpendicular to each other, and the two ends of the first connection hole 12 and the second connection hole 13 are "trumpet-shaped". The filler 2 is filled into the hollow structure 11; the pre-buried pipe 3 is installed in the first connection hole 12 and the second connection hole 13.

[0044] The filler 2 is arranged in the hollow structure 11 of the float body 1 to facilitate the float to float on the sea surface. If the float body 1 is damaged and water enters it, causing the float to sink, and the filler 2 fills the hollow structure 11, it can prevent seawater from quickly pouring into the float body 1. A first connecting hole 12 and a second connecting hole 13 are arranged on the top side wall of the float body 1, and pre-buried pipes 3 are respectively installed in the first connecting hole 12 and the second connecting hole 13. When it is necessary to connect two adjacent float bodies 1, a rope is used as a connecting piece, and the rope passes through the adjacent float bodies 1 in turn. The two ends of the first connecting hole 12 and the second connecting hole 13 are trumpet-shaped in order to increase the contact surface of the rope, avoid direct contact between the rope and the edge, and increase the service life of the rope.

[0045] In order to improve the service life of the floating body 1, the floating body 1 is made of ultra-high performance concrete. The floating body 1 includes: a floating part 14 and a sealing cover 16 arranged on the top of the floating part 14. The top of the floating part 14 has a receiving groove 141, and the receiving groove 141 is divided into multiple areas by a partition plate 15, and each area is filled with a filler 2. The sealing cover 16 is arranged on the top of the floating part 14, and the size of the sealing cover 16 just matches the size of the connection of the floating part 14. After the sealing cover 16 is connected to the floating part 14, a hollow chamber is formed between the sealing cover 16 and the receiving groove 141, and the first connecting hole 12 and the second connecting hole 13 are arranged in the sealing cover 16.

[0046] A receiving groove 141 is provided at the top of the floating part 14, and the receiving groove 141 is divided into a plurality of areas by a partition plate 15, and a filler 2 is provided in each area to improve the service life of the floating body 1. A sealing cover 16 is provided at the same time, and the first connecting hole 12 and the second connecting hole 13 are provided on the sealing cover 16, so as to facilitate the connection of adjacent floating bodies in the later stage.

[0047] In order to prevent the floating part 14 of the connected floating body 1 from colliding under the impact of waves and causing the floating part 14 to be broken, the cross-section of the floating part 14 is designed to be an isosceles trapezoidal structure, and its bottom edge is connected to the sealing cover 16. When the wave impacts the side wall of the floating part 14 of the floating body, the contact surface with the floating part 14 of the adjacent attached body is increased, thereby improving the service life of the floating part 14.

[0048] In another embodiment, if Figure 6 As shown, in order to increase the service life of the sealing cover 16 , a circle of thickened plate 161 is provided at the edge of the side where the sealing cover 16 is connected to the floating portion 14 .

[0049] In another embodiment, if Figure 6 As shown, in order to improve the structural strength of the sealing cover 16, a first reinforcing rib 162, a second reinforcing rib 163 and a third reinforcing rib 164 are provided on the side of the sealing cover 16 facing the floating portion 14, and a steel cage with four main bars and stirrups is provided inside the first reinforcing rib 162, the second reinforcing rib 163 and the third reinforcing rib 164.

[0050] The first reinforcing rib 162 is arranged along the length direction of the sealing cover 16, and the first connecting hole 12 is arranged in the middle of the reinforcing rib steel cage of the first reinforcing rib 162; the second reinforcing rib 163 is arranged along the width direction of the sealing cover 16; the third reinforcing rib 164 is arranged between two adjacent second reinforcing ribs 163, and the second connecting hole 13 is arranged in the middle of the reinforcing rib steel cage of the third reinforcing rib 164.

[0051] In other embodiments, Figure 6 As shown, one first reinforcing rib 162 is provided, three second reinforcing ribs 163 are provided, and two third reinforcing ribs 164 are provided.

[0052] In another embodiment, if Figure 1 , Figure 2 and Figure 6 As shown, in order to facilitate the installation of the photovoltaic panel, a photovoltaic component fastener installation groove 165 is set on the top of the sealing cover 16.

[0053] In another embodiment, in order to facilitate the rapid flow of water on the photovoltaic panels after the waves hit the photovoltaic panels, the top of the floating body 1 is provided with an inclined structure.

[0054] In one embodiment, one side of the floating body 1 opposite to the top is inclined toward the other side.

[0055] In another embodiment, if Figure 1 and Figure 2As shown, in order to improve the service life of the floating body 1, rubber plugs 4 are provided at both ends of the first connection hole 12 and the second connection hole 13, and a through hole for the cable to pass through is provided in the middle of the rubber plug 4. It should be noted that the shape of the rubber plug 4 matches the structure at both ends of the first connection hole 12 and the second connection hole 13. When two adjacent floating bodies collide, the rubber plugs 4 on the sealing cover 16 contact first to relieve part of the force generated by the collision.

[0056] In another embodiment, the filler 2 is EPS foam. EPS foam is used to increase the service life of the float. EPS foam has the advantage of less water absorption.

[0057] like Figure 7 As shown, a photovoltaic floating body assembly comprises: a plurality of offshore floating photovoltaic floating bodies as described above, a cable 5, a plurality of auxiliary cables 6 and a plurality of concrete gravity anchors 7. The cable 5 passes through the first connection hole 12 and the second connection hole 13 in each offshore floating photovoltaic floating body in turn to connect the plurality of offshore floating photovoltaic floating bodies; a plurality of auxiliary cables 6 are connected to the cable 5 at one end; a plurality of concrete gravity anchors 7 are arranged on the seabed, and the other ends of the auxiliary cables 6 are connected to the concrete gravity anchors 7.

[0058] The multiple photovoltaics are connected by concrete gravity anchors 7, and the connection method of cables 5 is to prevent the entire photovoltaic floating assembly from being broken apart when the waves hit. During the impact of the waves, since the two adjacent floating bodies are connected by cables 5, there is a space between the two adjacent floating bodies, and a rubber plug 4 is arranged between the two adjacent floating bodies to relieve part of the force generated by the collision.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
