Abstract
Description
Technical Field
[0001] The present invention relates to a support structure, and more particularly to a support structure for an offshore solar photovoltaic module. Background Art
[0002] Refer to Figure 1 , the currently common offshore solar device 1 includes a floating platform 11 that can float on the water surface, a support unit 12 fixed on the floating platform 11, and a solar panel 13 inclinedly placed at the top of the support unit 12. The support unit 12 includes four columns 121 erected on the floating platform 11 and divided into two lengths in total, and two connecting beams 122 each connecting two columns 121 of different lengths. The connecting beams 122 extend obliquely and are used to carry and fix the solar panel 13. The floating platform 11 can float on the sea, and by assembling multiple groups of offshore solar devices 1, a renewable solar power generation field can be constructed in the sea area. However, the machines and tools set up at sea ultimately need to face a complex marine environment. For example, the columns 121 need to constantly withstand the waves hitting from the side. The impact force generated by the lateral impact of the waves will cause flexure to the columns 121, and ultimately lead to the skew or fracture of the columns 121. Therefore, there is still room for improvement in the design of the current support unit 12. Summary of the Invention

[0017] The present invention will be described in detail below with reference to the drawings and embodiments.
[0018] Refer to Figure 2 , an embodiment of the offshore solar photovoltaic module support 2 of the present invention includes a floating body 21 extending along a length direction A, a first pillar 22 locked to the floating body 21 and extending along a height direction B perpendicular to the length direction A, a second pillar 23 locked to the floating body 21 at an interval along the length direction A with the first pillar 22 and extending along the height direction B, a reinforcing beam 24 extending obliquely along the length direction A and locking the first pillar 22 and the second pillar 23, and a bearing beam 25 extending along the length direction A and locking the first pillar 22 and the second pillar 23.
[0019] The floating body 21 includes an outer plate body 212 surrounding and defining a surrounding space 211 extending along the length direction A, a plurality of partition walls 213 connecting the outer plate body 212 and disposed in the surrounding space 211, and two tenons 214 protruding from the top surface of the outer plate body 212 along the height direction B and respectively locking the first pillar 22 and the second pillar 23. The partition walls 213 are spaced apart from each other along the length direction A and cooperate with the outer plate body 212 to divide the surrounding space 211 into a plurality of buffer grooves 215 spaced apart from each other along the length direction A. Each buffer groove 215 penetrates along a width direction C perpendicular to the height direction B and the length direction A. The buffer groove 215 can be a hole groove of different shapes according to requirements.
[0020] Refer to Figure 2 , Figure 3 , and Figure 4 , the first pillar 22 includes a first outer wall 221 extending along the width direction C, and two first side walls 222 spaced apart from each other along the width direction C and each extending from the first outer wall 221 along the length direction A towards the second pillar 23. The first outer wall 221 and the first side walls 222 cooperate to define a first extension groove 223 extending along the height direction B. The second pillar 23 includes a second outer wall 231 parallel to the first outer wall 221, and two second side walls 232 spaced apart from each other along the width direction C and each extending from the second outer wall 231 along the length direction A towards the first pillar 22. The second outer wall 231 and the second side walls 232 cooperate to define a second extension groove 233 extending along the height direction B. The tenons 214 are respectively disposed in the first extension groove 223 and the second extension groove 233.
[0021] Both ends of the reinforcing beam 24 are respectively extended into the first extension groove 223 and the second extension groove 233, and are locked to the first side wall 222 and the second side wall 232. The connection point D of the reinforcing beam 24 and the first support 22 is lower than the connection point E of the reinforcing beam 24 and the second support 23 along the height direction B, so that the reinforcing beam 24 extends obliquely along the length direction A. In this embodiment, the cross-sectional area of the reinforcing beam 24 is in a square shape.
[0022] The receiving beam 25 includes a top wall 251 and two end walls 252 that are spaced apart from each other along the width direction C and each extend from the top wall 251 along the height direction B towards the floating body 21. The connection point F of the receiving beam 25 and the first support 22 is higher than the connection point G of the receiving beam 25 and the second support 23 along the height direction B, so that the receiving beam 25 extends obliquely along the length direction A. In this embodiment, the inclination angle of the receiving beam 25 is smaller than the inclination angle of the reinforcing beam 24, and the inclination directions of the two are opposite. The top wall 251 and the end wall 252 cooperate to define a slot 253 that extends obliquely along the length direction A and for the tops of the first support 22 and the second support 23 to extend into, and the end wall 252 is locked to the first side wall 222 and the second side wall 232.
[0023] Refer to Figure 2 、 Figure 4 ,and Figure 5 In actual use of the present invention, as shown in Figure 5 , multiple floating pipes 31 extending along the width direction C are used to connect multiple offshore solar photovoltaic module brackets 2 for arranging multiple solar panels 33. Each floating pipe 31 can penetrate the floating bodies 21 arranged at intervals along the width direction C. Each solar panel 33 is arranged on two adjacent offshore solar photovoltaic module brackets 2, and the solar panel 33 is locked to the receiving beam 25 of each offshore solar photovoltaic module bracket 2. Preferably, a plurality of long grooves 254 spaced apart from each other along the length direction A can be formed on the top wall 251 of the receiving beam 25. Each long groove 254 extends along the width direction C and is used for locking the solar panel 33. The design that the long groove 254 extends along the width direction C allows the locking position of the solar panel 33 to be adjusted along the width direction C and is not limited to a single point, so that the tolerance between adjacent solar panels 33 can be eliminated. The floating bodies 21 are arranged at intervals along the width direction C, and in cooperation with the buffer grooves 215 opened along the width direction C, the effect of wave elimination and increased overall stability can be achieved.
[0024] Since the offshore solar photovoltaic module brackets 2 are connected and used in multiple groups along the width direction C, most of the first struts 22 and the second struts 23 of the offshore solar photovoltaic module brackets 2 mainly bear the impact of sea waves coming along the length direction A. By extending the first side wall 222 and the second side wall 232 along the length direction A, and the cross-sections of the first strut 22 and the second strut 23 in the height direction B are generally U-shaped, the area moment of inertia of the first and second struts 22, 23 can be increased, thereby enhancing the buckling resistance of the first strut 22 and the second strut 23. At the same time, the U-shaped appearance can also produce the effect of saving materials. In addition, the inclined and extended reinforcing beam 24 can further enhance the buckling resistance in the length direction A, increasing the overall rigidity and durability.
[0025] It should be specifically noted that each offshore solar photovoltaic module bracket 2 may further include two position-limiting rods 26 respectively connecting the first outer wall 221 and the second outer wall 231. Each position-limiting rod 26 extends along the width direction C, and one end is locked to the first outer wall 221 or the second outer wall 231, while the other end is locked to the first outer wall 221 or the second outer wall 231 of another offshore solar photovoltaic module bracket 2. Except for the head and tail ends, the first outer wall 221 (or the second outer wall 231) of most offshore solar photovoltaic module brackets 2 is connected to two position-limiting rods 26, and the two position-limiting rods 26 on the same first outer wall 221 (or the same second outer wall 231) overlap inside and outside along the length direction A. By connecting the offshore solar photovoltaic module brackets 2 along the width direction C through the position-limiting rods 26, the tolerance of the first strut 22 and the second strut 23 in the length direction A is improved, so that the offshore solar photovoltaic module brackets 2 at the head and tail ends can cope with the impact of sea waves coming from the width direction C.
[0026] In summary, the present invention has better buckling resistance, so it can better adapt to the complex marine environment, which is beneficial to the installation of offshore solar photovoltaic modules. At the same time, when the floating bodies 21 are arranged at multiple intervals, they can also produce the effects of wave dissipation and buffering, enhancing the stability of the offshore solar photovoltaic module brackets 2. Therefore, the purpose of the present invention can indeed be achieved.
