Description

Technical Field

[0001] The present invention relates to an auxiliary device for offshore solar power generation, and particularly to a wind and wave reduction cofferdam device and system for offshore solar photovoltaics. Background Art

[0002] Compared with setting solar power generation equipment on land, offshore solar photovoltaics is to set solar power generation equipment on the sea surface at a certain distance from land. In addition to reducing the adverse impact on the land that requires sunlight, it also has the advantage of being able to fully receive sunlight and exert better power generation benefits. However, for so-called offshore solar power generation, after all, solar power generation equipment is set on the sea surface far from land. In addition to considering making use of a wider range of solar sunlight as much as possible, it is also necessary to avoid affecting offshore activities near adjacent land. Therefore, usually, a large-area solar power generation equipment is constructed, and the constructed power generation equipment is positioned far offshore where there are strong winds and big waves. Therefore, although the constructed solar power generation equipment occupies a large area and is expected to generate a large amount of electricity, it also has a large wind and wave receiving area and is easily damaged by strong winds and big waves in the open sea, which not only increases the maintenance cost but may also not be able to generate the expected amount of electricity. Summary of the Invention

[0003] The purpose of the present invention is to provide a wind and wave reduction cofferdam device and system for offshore solar photovoltaics that can provide necessary protection for offshore solar photovoltaic equipment against sea winds and waves.

Each of the bent pipes has two extension segments integrally connected to each other and extending along two extension lines that form a right angle with each other.

[0006] The protection unit includes side brackets installed on the pedestals and located beside the second axis, and at least one baffle fixed to the side brackets and formed with a plurality of spoiler holes penetrating in a direction parallel to the second axis.

Among them, the baffle is located on the inner side close to the inner field, and the bottom pipes are arranged at intervals outward in a direction away from the inner field.

[0009] In the wave attenuation and wind reduction system for offshore solar photovoltaics of the present invention, each of the link modules includes a plurality of bent pipes respectively connected between two bottom pipes of adjacent wave attenuation and wind reduction cofferdam devices for offshore solar photovoltaics.

[0010] In the wave attenuation and wind reduction system for offshore solar photovoltaics of the present invention, each of the bent pipes has two extension segments that are integrally connected to each other and extend along two extension lines that are perpendicular to each other.

[0011] The beneficial effect of the present invention is that: on the plane formed by the first axis and the second axis, the lattice-like integral form jointly formed by the base and the bottom pipes can achieve the effect of gradually reducing the sea waves coming from all around; and then in cooperation with the protection unit, with the baffle facing the windward side, in addition to directly blocking strong winds through the solid structure, the wind force can also be greatly reduced through the spoiler holes, so as to achieve a perfect protection effect in response to the sea breeze in the open sea.

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Refer to Figure 1 , which is a device embodiment of the wind-reducing and wave-damping cofferdam device for offshore solar photovoltaics of the present invention. This device embodiment includes a base unit 1 and a protection unit 2 connected to the base unit 1. This device embodiment is suitable for being arranged at intervals with a plurality of solar power generation devices 8 suitable for being arranged on the sea surface as shown in Figure 2 . Preferably, a system embodiment of the wind-reducing and wave-damping system for offshore solar photovoltaics of the present invention is constructed by four such device embodiments, thereby surrounding and defining an inner field Z for setting the solar power generation devices 8, and achieving a perfect protection effect on the solar power generation devices 8 completely from all around. Accordingly, as shown in Figure 1 , the part extending along a first axis L1 is regarded as one device embodiment for illustration, and the length of this device embodiment along the first axis L1 can also be freely adjusted according to requirements.

[0020] Refer to Figure 3 and cooperate with Figure 1 , the base unit 1 includes a plurality of pedestals 11 arranged at intervals along the first axis L1 and each defining four through holes 110 penetrating along a direction parallel to the first axis L1, a plurality of bottom pipes 12 respectively penetrating through the through holes 110 of the pedestals 11 and spaced from each other along a second axis L2 perpendicular to the first axis L1, a plurality of support frames 15 positioned between adjacent bottom pipes 12, and a plurality of pedals 16 arranged on the support frames 15 and suitable for being stepped on and walked by an operator during maintenance. Specifically, the pedestal 11 is the main basic structure of this embodiment, so it is preferably made of a material with better rigidity. And each of the bottom pipes 12 can be selected according to the length to which this device embodiment is to extend, and a sufficient number of the pedestals 11 are spaced at an appropriate distance to form a main structure extending along the first axis L1.

[0021] At the same time, refer to Figures 1 to 3, the protection unit 2 includes a side bracket 21 installed on the base 11 and located beside the second axis L2, a plurality of baffles 22 fixed to the side bracket 21, and a plurality of lugs 23 for fixing the baffles 22 to the side bracket 21. Specifically, the baffle 22 is a rigid plate and can be easily assembled through the lugs 23. The baffle 22 is formed with a plurality of flow disturbance holes 220 penetrating in a direction parallel to the second axis L2 by means of perforating holes. Preferably, the baffle 22 is arranged on the side opposite to the solar power generation device 8 to achieve a protection effect on the solar power generation device 8 arranged in the inner field Z.

[0022] Refer to Figure 4 and Figure 5 cooperate with Figure 1 , when the device embodiment of the present device is to be arranged on the sea surface at a certain distance from the land, it is usually assembled into the system embodiment at a position closer to the land first. The system embodiment includes four device embodiments of the present device and four link modules 3 for connecting the device embodiments. Each of the link modules 3 includes three bent pipes 31 connected between two bottom pipes 12 of adjacent device embodiments and one connector 32 connected between two side brackets 21 of adjacent device embodiments. And as Figure 6 shown, each of the bent pipes 31 has two extension segments 311 that are integrally connected to each other and extend along two extension lines that are perpendicular to each other. Thus, a plurality of device embodiments can be connected to each other to enclose the inner field Z located in the center. Among them, the baffle 22 is located inside and close to the inner field Z, and the bottom pipes 12 are arranged at intervals outward in a direction away from the inner field Z.

[0023] The assembled system embodiment will be moved to a pre-set offshore location by other powered vessels. When the system embodiment is moved to the set location, a positioning effect will be generated through the anchoring mechanism. Since the protection unit 2 of the device embodiment completely surrounds the inner field Z under the stable connection of the baffle 22 through the connecting member 32, strong winds that may blow towards the system embodiment from all around can be initially blocked by the baffle 22 surrounding the outer area of the inner field Z, and the air flow can be dispersed through the spoiler holes 220 of the baffle 22, achieving the effect of significantly reducing the influence of the wind force. Additionally, for the waves that are bound to occur on the sea surface, the two-dimensional structure formed by the base 11 and the bottom pipe 12 of the base unit 1 can form a layer-by-layer wave dissipation structure for the sea waves in the direction along the first axis L1 through the blocking effect of the spaced-apart bases 11; similarly, in the direction along the second axis L2, a layer-by-layer wave dissipation structure for the sea waves is formed through the spaced-apart bottom pipes 12. Therefore, no matter from where the sea waves slap towards the system embodiment (or any device embodiment of the present invention), the base unit 1 can exert a wave dissipation effect and reduce the influence of the sea waves on the setting stability of the system embodiment.
