Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic floating bodies, and in particular to a combined photovoltaic floating body capable of weakening underwater surges. Background Art

[0002] With the shortage of available land resources in China and the increasing difficulty of land transfer, and the large construction area required for photovoltaic power stations, the cost of land photovoltaic construction is increasing, and the overall social benefits are decreasing. However, the water area in southern my country is extensive, and most of the water surface is idle. As a new type of photovoltaic power generation model, floating photovoltaic power stations on water have begun to develop on a large scale. Floating photovoltaic power stations on water use bracket devices to install photovoltaic modules on a floating body, and then the photovoltaic modules float on the water to generate electricity.

[0003] Chinese patent "CN218276546U" discloses a floating photovoltaic platform and photovoltaic system, including a floating unit, which includes a mesh flexible support member, a number of photovoltaic bearing floats and a peripheral frame float, wherein the mesh flexible support member is used to be arranged close to the surface of the water body in a flat manner; a number of photovoltaic bearing floats are installed on the mesh flexible support member, and the top surface of each photovoltaic bearing float can be laid and installed with a number of photovoltaic modules; the peripheral frame float is surrounded by the mesh flexible support member and is fixedly connected to the outer edge of the mesh flexible support member. When the patented product encounters severe working conditions such as large winds and waves, since the mesh flexible support member is arranged close to the surface of the water body in a flat manner, the mesh flexible support member can adaptively deform along with the wave movement to resist the wind and waves.

[0004] Although the above patented product has a certain resistance to wind and waves, its resistance to wind and waves depends entirely on its own structure, which resists wind and waves by adaptively deforming with the movement of waves; however, this adaptive deformation has a certain limit. When the wind and waves gradually increase, it will inevitably gradually exceed the limit of its adaptive deformation; and even if its own structure can withstand larger wind and waves, the photovoltaic panels installed on it are easily damaged by up and down fluctuations. In addition, offshore photovoltaic platforms not only have to face waves on the water surface, but also face surging currents under the water surface, which cannot be solved by existing technologies. Utility Model Content

[0005] The utility model provides a combined photovoltaic floating body that can weaken underwater surges, and its purpose is to dissipate both the waves on the water surface and the underwater surges through an inverted triangular anti-surge dam body, thereby solving the problem of weak wind and wave resistance in the prior art.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] The utility model provides a combined photovoltaic floating body that can weaken underwater surges, including a plurality of groups of movably connected photovoltaic platforms, photovoltaic panels arranged on the photovoltaic platforms, and a plurality of groups of anti-surge dam bodies arranged around the photovoltaic platforms and movably connected to the photovoltaic platforms;

[0021] The utility model is provided with a surge dam body around the photovoltaic platform. The overall shape is an inverted triangle, most of which is submerged under the water surface.

[0034] The utility model provides a combined photovoltaic floating body 10 that can weaken underwater surges. The combined photovoltaic floating body 10 adopts a modular design and can expand its area according to demand. The combined photovoltaic floating body 10 dissipates the waves on the water surface and the underwater surges through an anti-surge dam body 130, thereby improving the ability to resist wind and waves.

[0035] like Figures 1 to 6As shown, the combined photovoltaic floating body 10 includes a plurality of groups of movably connected photovoltaic platforms 120, photovoltaic panels 110 disposed on the photovoltaic platforms 120, and a plurality of groups of anti-surge dam bodies 130 disposed around the photovoltaic platforms 120 and movably connected to the photovoltaic platforms 120;

[0036] The anti-surge dam body 130 includes a plurality of buoyancy tubes 131, a plurality of submerged tubes 132 and a plurality of fixing plates 133; the plurality of buoyancy tubes 131 are arranged in the same plane and are arranged at the top; the plurality of submerged tubes 132 are divided into a plurality of layers and are all arranged below the buoyancy tubes 131; the buoyancy tubes 131 are connected to the submerged tubes 132 via the fixing plates 133, and the submerged tubes 132 are provided with a plurality of water inlet holes.

[0037] Among them, facing the sky is up, and facing the seabed is down, and the same applies to the following text.

[0038] The photovoltaic platform 120 includes two layers of HDPE material pipes, including a large diameter buoyancy tube 121 located in the lower layer, and a photovoltaic panel mounting tube 122 located in the upper layer for fixing the photovoltaic panel 110. The distance between the upper and lower layers is supported and the height is controlled by an elevated bracket plate 123; the buoyancy tube 121 is used to provide buoyancy for the photovoltaic platform 120 so that it floats on the sea surface, and the photovoltaic panel mounting tube 122 is arranged above the buoyancy tube 121. Such an elevated design is mainly to prevent waves from hitting the back of the photovoltaic panel 110 and causing damage.

[0039] Furthermore, a group of the photovoltaic platforms 120 includes two buoyancy tubes 121, three photovoltaic panel mounting tubes 122 and four elevated support plates 123. The two buoyancy tubes 121 are arranged in the same plane, and the three photovoltaic panel mounting tubes 122 are arranged in the same plane and are evenly spaced. The elevated support plates 123 are in the shape of an inverted isosceles trapezoid, and the four elevated support plates 123 are evenly spaced and arranged in parallel. The buoyancy tubes 121 and the photovoltaic panel mounting tubes 122 are fixed by the elevated support plates 123.

[0040] Furthermore, the two ends of the buoyancy tube 121 are respectively provided with joints 121a, and the joints 121a can be selected as male joints 121a or female joints 121a as needed. Such a design facilitates the expansion of the photovoltaic platform 120 in the longitudinal direction (i.e., the axial direction of the buoyancy tube 121, the same below), and facilitates the expansion of the area of ​​the photovoltaic platform 120. In the longitudinal direction, two adjacent photovoltaic platforms 120 are connected by the cooperation of the male joint 121a and the female joint 121a.

[0041] Furthermore, joints 121 a are also provided at both ends of the photovoltaic panel mounting tube 122 .

[0042] Furthermore, each photovoltaic panel mounting tube 122 is provided with a plurality of photovoltaic panel mounting clamps 122 a for fixing the photovoltaic panel 110 .

[0043] Furthermore, the number of each photovoltaic panel mounting clamp 122a is six.

[0044] Furthermore, in the lateral direction, two adjacent photovoltaic platforms 120 are flexibly connected via a movable connecting tube 140 .

[0045] Furthermore, both ends of the movable connecting pipe 140 are provided with pipe hoops 141, and the pipe hoops 141 are used to be movably connected to the pipe fittings. In the connection of two adjacent photovoltaic platforms 120, the pipe hoops 141 at both ends of the movable connecting pipe 140 are respectively connected to the buoyancy pipes 121 of the two photovoltaic platforms 120.

[0046] The anti-surge dam body 130 includes three buoyancy tubes 131 and three submerged tubes 132. The three buoyancy tubes 131 are arranged in the same plane and at the top layer. The three submerged tubes 132 are divided into two groups, one group of two tubes is located in the middle, and the other group of one tube is located at the bottom. The three layers of tubes are arranged in parallel and evenly spaced, and the overall shape is an inverted triangle. When the waves and surges hit the buoyancy tubes 131 and the submerged tubes 132 respectively, they will be sheared and broken by them, and then dissipated and weakened.

[0047] Further, both ends of the second buoyancy tube 131 and both ends of the submerged tube 132 are provided with joints 121a, and the joints 121a can be selected as male joints 121a or female joints 121a according to needs, so as to facilitate the expansion of the anti-surge dam body 130 along the length direction of the second buoyancy tube 131. Two adjacent anti-surge dam bodies 130 are movably connected through the cooperation of the male joints 121a and the female joints 121a.

[0048] In the lateral direction, the photovoltaic platform 120 is movably connected to the surge protection dam body 130 through a plurality of movable connecting tubes 140 ; ​​specifically, one end of the movable connecting tube 1 140 is sleeved on the buoyancy tube 1 121 , and the other end is sleeved on the buoyancy tube 2 131 .

[0049] In the longitudinal direction, the photovoltaic platform 120 is movably connected to the anti-surge dam body 130 through a plurality of movable connecting pipes 150 .

[0050] Furthermore, a plug plate 151 is provided at one end of the movable connecting tube 150, and a pipe clamp 141 is provided at the other end; when the photovoltaic platform 120 is connected to the anti-surge dam body 130, the outer end of the buoyancy tube 121 of the photovoltaic platform 120 is a female joint 121a, the plug plate 151 is inserted into the female joint 121a and is rotatably connected through a pin shaft, and the pipe clamp 141 of the movable connecting tube 150 is sleeved on the buoyancy tube 131 of the anti-surge dam body 130.

[0051] The photovoltaic panel 110 platform is connected to an underwater anti-surge dam 130. The submerged pipe 132 below the water surface is filled with seawater through the water inlet hole on the pipe fitting to increase its own weight, sink below the water surface, and is fixed to the seabed by an anchoring system. The buoyancy tube 131 on the water surface is a hollow buoyancy tube that floats on the water surface. The main function of the anti-surge dam 130 is that the surface buoyancy tube 131 dissipates the clutter and tail waves of the larger waves after the outermost wave-breaking dam breaks up, and the underwater submerged pipe 132 dissipates the underwater surge.

[0052] In actual use, several groups of photovoltaic platforms 120 are connected and extended horizontally and vertically to form a rectangular photovoltaic panel 110 installation area, and the anti-surge dam body 130 is arranged along the four sides of the photovoltaic panel 110 installation area and encloses it, thus forming a group of combined photovoltaic floating bodies 10; several groups of combined photovoltaic floating bodies 10 are evenly spaced and aggregated together to form a rectangular photovoltaic power generation area, and the photovoltaic power generation area is surrounded by an outer wave-breaking dam composed of anti-surge dam bodies 130; in this way, a triple defense is formed, in which the outermost wave-breaking dam first dissipates larger waves and surges, and then the anti-surge dam body 130 eliminates a part of the waves and surges, and finally the remaining energy is absorbed by the adaptive deformation of the combined photovoltaic floating body 10, which greatly improves the wind and wave resistance of the new type of use.

[0053] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
