[0037] Most existing photovoltaic brackets adopt a multi-layer water tank structure design, using the upper water tank to collect the water falling from the longitudinal gap and the transverse gap of the photovoltaic module, and then the water collected by the upper water tank is collected in the lower water tank for centralized discharge. However, when the upper water tank converges to the lower water tank with a multi-layer water tank structure, it is easy for part of the water flow to splash out of the lower water tank due to excessive convergence water volume, causing leakage at the bottom of the photovoltaic bracket, affecting the diversion stability and reliability of the photovoltaic bracket. In addition, the overall assembly process of the multi-layer water tank structure is relatively cumbersome, which reduces the convenience of assembling the photovoltaic bracket. In view of the above problems, the utility model proposes a bearing structure 100.
[0038] Reference Figures 1 to 10 In an embodiment of the utility model, the bearing structure 100 includes a main beam 10 and a water tank frame 30. The main beam 10 is used to connect the support frame 200. A confluence cavity 11 is formed in the main beam 10. The surface of the main beam 10 is provided with a confluence hole 13 connected to the confluence cavity 11; the water tank frame 30 is connected to the main beam 10, and a first water collecting trough 311 and a second water collecting trough 331 are formed on the surface of the water tank frame 30 facing away from the main beam 10. The extension direction of the first water collecting trough 311 is set at an angle to the extension direction of the second water collecting trough 331. The first water collecting trough 311 is connected to the second water collecting trough 331. The bottom wall of the first water collecting trough 311 is provided with a flow hole 313, and the flow hole 313 is connected to the confluence hole 13 accordingly.
[0039] It is understandable that in a photovoltaic power station, photovoltaic modules 2000 are mostly installed in an array on a photovoltaic support 1000, and there is usually a certain gap between two photovoltaic modules 2000 adjacent to each other longitudinally and between two photovoltaic modules 2000 adjacent to each other laterally, so that the photovoltaic modules 2000 can be separated from each other to reduce interference. Photovoltaic power stations can usually be set up in environments with large open areas such as building roofs or mountain plains, so that the photovoltaic power station can better receive and convert light energy and improve the light energy utilization rate of the photovoltaic power station. At this time, when the photovoltaic power station encounters thunderstorms or uses a cleaning device to spray water on the photovoltaic components 2000 for cleaning, the water falling on the photovoltaic components 2000 can flow out from the gap between two adjacent photovoltaic components 2000 along the edges of the photovoltaic components 2000, and the photovoltaic bracket 1000 can be provided with water troughs corresponding to the gap between two longitudinally adjacent photovoltaic components 2000 and the gap between two laterally adjacent photovoltaic components 2000 below the photovoltaic components 2000, so that water flowing through the gap between the photovoltaic components 2000 can flow into the water trough, preventing water from dripping from the gap between the photovoltaic components 2000 into the installation position of the photovoltaic bracket 1000, so that the environment at the bottom of the photovoltaic bracket 1000 can be kept dry, and the dark environment at the bottom of the photovoltaic bracket 1000 is prevented from being damp and breeding mold due to water accumulation, which is conducive to better utilization of the space occupied by the photovoltaic power station to place other photovoltaic equipment or sundries. Since multiple photovoltaic modules 2000 are arranged in an array on the photovoltaic support 1000, corresponding water troughs need to be set in the gap between each two adjacent photovoltaic modules 2000. At this time, the water collected by multiple water troughs on the photovoltaic support 1000 can be converged to one place for centralized discharge to ensure the stable operation of the photovoltaic power station.
[0040] In the present application, the photovoltaic support 1000 can use the support frame 200 to support the bearing structure 100, so that the bearing structure 100 can stably support the photovoltaic assembly 2000. The support frame 200 can be a support column or a triangular support, etc. By using a rectangular steel material to set the main beam 10 connected to the support frame 200 in the bearing structure 100, the hollow structure of the rectangular steel material can be used to form a confluence cavity 11 with a certain degree of airtightness inside the main beam 10. By setting a confluence hole 13 connected to the confluence cavity 11 on the surface of the main beam 10 facing away from the support frame 200, when the water tank frame 30 is connected and installed on the main beam 10, the flow hole 313 of the bottom wall of the first water collecting tank 311 is set corresponding to the position of the confluence hole 13, so that the flow hole 313 and the confluence hole 13 can overlap and connect, so as to realize the connection between the first water collecting tank 311 and the confluence cavity 11. A second water collecting trough 331 is also formed on the water trough frame 30. By making the extension direction of the first water collecting trough 311 and the extension direction of the second water collecting trough 331 form an angle, and connecting the first water collecting trough 311 with the second water collecting trough 331, the water trough frame 30 can form a criss-crossing water trough drainage system using the first water collecting trough 311 and the second water collecting trough 331, and by connecting the first water collecting trough 311 with the confluence cavity 11 through the flow hole 313 and the confluence hole 13, the main beam 10 can form a confluence drainage structure of the water trough structure, reducing the confluence water trough setting of the water trough structure, effectively simplifying the overall structure of the water trough frame 30, and facilitating better assembly of the photovoltaic bracket 1000. Furthermore, when the photovoltaic module 2000 is installed on the bearing structure 100, the photovoltaic module 2000 can be set above the water tank frame 30, and the two adjacent sides of the frame of the photovoltaic module 2000 are placed corresponding to the first water collecting tank 311 and the second water collecting tank 331, so that the first water collecting tank 311 and the second water collecting tank 331 can be respectively located at the horizontal gap and the longitudinal gap between multiple photovoltaic modules 2000. When rain or clean water falls on the photovoltaic module 2000, the water can flow into the first water collecting tank 311 and the second water collecting tank 331 along the edge of the frame of the photovoltaic module 2000, and the water in the second water collecting tank 331 flows into the first water collecting tank 311, so that the water flows in the first water collecting tank 311 through the flow hole 313 and the confluence hole 13 into the confluence cavity 11 of the main beam 10 for centralized discharge, thereby realizing the drainage function of the photovoltaic bracket 1000.
[0041] By utilizing the hollow structure of the main beam 10 to form a confluence cavity 11, the bearing structure 100 can form a closed confluence channel, and then after the trough structure utilizes the first water collecting trough 311 and the second water collecting trough 331 to collect the accumulated water on the photovoltaic module 2000, the flow holes 313 on the bottom wall of the first water collecting trough 311 can be utilized to converge the water flow into the confluence cavity 11 of the main beam 10 for centralized discharge, thereby effectively avoiding water splashing when the bearing structure 100 converges the water flow, and preventing the water flow from overflowing to the bottom of the photovoltaic bracket 1000 when the photovoltaic bracket 1000 is drained, so that the photovoltaic bracket 1000 can achieve a more stable and reliable drainage effect, further improving the practicality and reliability of the bearing structure 100.
[0042] Among them, the bearing structure 100 can use a fastening structure with a longer length to connect the main beam 10 and the photovoltaic module 2000; or the structural strength of the water tank frame 30 can be increased, so that the fastening structure is set on the water tank frame 30 to connect and fix the photovoltaic module 2000, so as to realize the stable bearing installation of the photovoltaic module 2000 by the bearing structure 100. The water tank structure can make the first water collecting tank 311 extend horizontally and the second water collecting tank 331 extend horizontally and longitudinally, and then when the photovoltaic bracket 1000 uses the tilting setting of the bearing structure 100 to adjust the installation angle of the photovoltaic module 2000, the second water collecting tank 331 can be tilted with the bearing structure 100, so that the water flow in the second water collecting tank 331 can flow better into the first water collecting tank 311 under the action of gravity, which is conducive to better guaranteeing the confluence and discharge of water flow. Similarly, the main beam 10 can also be extended along the horizontal longitudinal direction, so that the water flowing through the first water collecting trough 311 and converging into the confluence cavity 11 of the main beam 10 can better flow to the side of the supporting frame body close to the installation plane of the photovoltaic bracket 1000 under the action of gravity, which is beneficial to improve the drainage efficiency of the photovoltaic bracket 1000, reduce the water blockage on the supporting structure 100, and further improve the structural stability and reliability of the photovoltaic bracket 1000.
[0043] Reference Figure 6 , Figure 7 and Fig. 9 In one embodiment of the utility model, the bottom wall of the first water collecting trough 311 is provided with a guide edge 315 around the flow hole 313, and the guide edge 315 is bent toward the main beam 10 and inserted into the confluence hole 13.
[0044] In this embodiment, the water tank frame 30 can use stamping technology to form a guide edge 315 at the position of the bottom wall of the first water collecting tank 311 corresponding to the flow hole 313, or a circular ring can be welded at the edge of the flow hole 313 to form a guide edge 315, so that the first water collecting tank 311 can be formed into a funnel structure by using the guide edge 315 on the side facing the main beam 10, so that when the water tank frame 30 is installed on the main beam 10, the guide edge 315 can be set in the flow confluence cavity 11 through the confluence hole 13, and then When the water in the first water collecting trough 311 flows through the flow hole 313, it can flow more smoothly into the confluence cavity 11 under the diversion effect of the diversion edge 315. At the same time, the diversion edge 315 can block the gap between the water trough frame 30 and the main beam 10, effectively preventing the water from flowing into the gap between the water trough frame 30 and the main beam 10 during the process of entering the confluence cavity 11 through the flow hole 313 and overflowing to the bottom of the photovoltaic support 1000 with a certain probability, further improving the drainage stability and reliability of the photovoltaic support 1000. Among them, the diversion edge 315 and the bottom wall of the first water collecting trough 311 can be set in an arc bend, so that the diversion edge 315 can form a diversion surface with a certain curvature to achieve a better diversion effect.
[0045] Reference Figures 3 to 5 In one embodiment of the utility model, the water tank frame 30 includes at least two first trough body beams 31 and a second trough body beam 33. At least two first trough body beams 31 are arranged at intervals along the extension direction of the main beam 10 and are connected to the main beam 10. A first water collecting trough 311 is formed on the surface of the first trough body beam 31 facing away from the main beam 10; the second trough body beam 33 is arranged between two adjacent first trough body beams 31, and a second water collecting trough 331 is formed on the surface of the second trough body beam 33. The two ends of the second trough body beam 33 are respectively overlapped on the notch edges of the two first water collecting troughs 311.
[0046] In this embodiment, the water tank frame 30 can be formed by combining and splicing at least two first tank beams 31 and second tank beams 33. The first tank beam 31 and second tank beam 33 can be formed by processing and producing the structure of channel steel, so that the surface of the first tank beam 31 can be recessed to form the first water collecting tank 311, and the surface of the second tank beam 33 can be recessed to form the second water collecting tank 331. The first tank beam 31 and second tank beam 33 made of channel steel can better simplify the overall structure of the water tank frame 30, and further improve the assembly convenience and practicality of the bearing structure 100. Among them, the water tank structure can use at least two first tank beams 31 to be arranged in sequence along the extension direction of the main beam 10. The bearing structure 100 can use multiple first tank beams 31 to more quickly collect water flow to the confluence cavity 11 of the main beam 10 for discharge. At the same time, the bearing structure 100 can form multiple arranged first water collecting tanks 311 corresponding to multiple rows of photovoltaic modules 2000, ensuring the overall drainage stability and reliability of the photovoltaic support 1000. The second trough beam 33 can be arranged between two adjacent first trough beams 31, wherein the number of second trough beams 33 can be set correspondingly according to the number of photovoltaic modules 2000 arranged along the extension direction of the first trough beams 31, by making the two ends of the second trough beam 33 located at the notch of the first water collecting trough 311 of the two adjacent first trough beams 31, and making the end of the second trough beam 33 overlap the notch edge of the first water collecting trough 311, and by providing a water outlet connected to the second water collecting trough 331 on the end face of the second trough beam 33, the water flow in the second water collecting trough 331 can flow from the end of the second trough beam 33 into the first water collecting trough 311, which is conducive to better realizing the drainage distribution on the bearing structure 100, and further improving the stability and reliability of the bearing structure 100.
[0047] Reference Figure 4 and Figure 5 In one embodiment of the present invention, two ends of the second trough beam 33 are respectively provided with guide inclined plates 333 , the guide inclined plates 333 are arranged in the first water collecting trough 311 , and are bent toward the bottom wall of the first water collecting trough 311 .
[0048] In this embodiment, the second trough beam 33 can be bent at the bottom edge of the end to form a guide inclined plate 333, and the guide inclined plate 333 is inclined toward the slot of the first water collecting trough 311. Therefore, under the guiding effect of the guide inclined plate 333, the water flow in the second water collecting trough 331 can be smoothly and obliquely flowed into the first water collecting trough 311, reducing the splashing of water when it flows from the second water collecting trough 331 into the first water collecting trough 311, better reducing the overflow of water in the bearing structure 100, and further improving the drainage stability and reliability of the bearing structure 100.
[0049] Reference Figure 4 , Figure 6 and Figure 7 In one embodiment of the utility model, the main beam 10 is provided with a fixing clamp 15 , which is connected to the surface of the main beam 10 and clamps and fixes the first trough beam 31 .
[0050] In this embodiment, the bearing structure 100 can be provided with a fixing clamp 15 installed on the main beam 10. The fixing clamp 15 can be provided in a U shape, so that the fixing clamp 15 can be buckled and installed on the main beam 10, and enclosed with the surface of the main beam 10 to form a clamping space. At this time, by setting the size of the fixing clamp 15 to correspond to the outer diameter size of the first trough beam 31, the fixing clamp 15 can clamp the first trough beam 31 and connect and fix it on the surface of the main beam 10, so that the first trough beam 31 can be firmly clamped in the clamping space, and the installation and fixation between the main beam 10 and the first trough beam 31 can be achieved. By clamping and fixing the first trough beam 31 with the fixing clamp 15, the shaking of the first trough beam 31 on the main beam 10 can be better limited, which is conducive to better preventing the water in the first water collecting tank 311 from being shaken and overflowing with a certain probability, and further improving the structural stability and reliability of the bearing structure 100. Among them, the fixing clamp 15 can be provided with a protruding structure at a position facing the first water collecting trough 311, so that the fixing clamp 15 can use the protruding structure to pass through the slot of the first water collecting trough 311 and be set in the first water collecting trough 311, and abut against the inner wall of the first water collecting trough 311, so that the fixing clamp 15 can abut against the inner wall and outer wall of the first trough body beam 31, so that the fixing clamp 15 can better clamp and fix the first trough body beam 31, and further improve the connection stability and reliability between the main beam 10 and the first trough body beam 31.
[0051] Reference Figure 3 and Figure 4 In one embodiment of the utility model, the bearing structure 100 also includes a secondary beam 50, which is connected to the main beam 10 and is arranged between two adjacent first trough beams 31. The extension direction of the secondary beam 50 is set at an angle to the extension direction of the main beam 10, and the second trough beam 33 is connected to the secondary beam 50.
[0052] In this embodiment, the bearing structure 100 can be provided with a secondary beam 50 between any two adjacent first trough beams 31, and the extension direction of the secondary beam 50 can be consistent with the extension direction of the first trough beam 31, and the surface of the secondary beam 50 facing away from the main beam 10 is located in the same plane as the surface where the notch of the first trough beam 31 is located, so that the secondary beam 50 can connect and support the second trough beam 33 overlapped between the two adjacent first trough beams 31, so that the second trough beam 33 can better carry a larger amount of water. In addition, when the bearing structure 100 is provided with multiple main beams 10 to support and fix the water tank frame 30, the secondary beam 50 can be used to connect the multiple main beams 10, and the secondary beam 50 and the main beam 10 can be combined to form a frame structure with a certain structural strength, so that the bearing structure 100 can more stably and reliably support and fix the photovoltaic module 2000, further improving the overall structural stability and reliability of the bearing structure 100.
[0053] Reference Figures 1 to 4 In one embodiment of the present invention, the bearing structure 100 further includes a mounting member 70 , which is connected to the first trough beam 31 and the secondary beam 50 and is used to mount and fix the photovoltaic assembly 2000 .
[0054] In this embodiment, the bearing structure 100 can be connected to the mounting member 70 on the side of the first tank beam 31 facing away from the main beam 10 and the side of the secondary beam 50 facing away from the main beam 10. The mounting member 70 can be used to connect and fix the photovoltaic assembly 2000 placed on the tank frame 30. The mounting member 70 can be fastened to the bottom edge of the frame of the photovoltaic assembly 2000 by bolts, so that the photovoltaic assembly 2000 is installed and fixed on the bearing structure 100. In addition, the mounting member 70 can also use a pressing block to press the surface of the frame of the photovoltaic assembly 2000 facing away from the bearing structure 100, so that the mounting member 70 can more firmly connect the photovoltaic assembly 2000 and the bearing structure 100, further improving the load of the photovoltaic assembly 2000. Among them, when the mounting member 70 is assembled on the first tank beam 31, it can be erected at the notch of the first water collecting tank 311, and the mounting member 70 clamps and fixes the outer wall and inner wall of the first tank beam 31 to achieve a stable connection and assembly of the mounting member 70 on the first tank beam 31. When the mounting member 70 is connected to the secondary beam 50, the second trough beam 33 can also be clamped and fixed, so that the mounting member 70 can not only fasten the photovoltaic module 2000, but also connect and fix the second trough beam 33 and the secondary beam 50, which is conducive to better simplifying the component arrangement of the bearing structure 100 and further improving the assembly convenience of the bearing structure 100. At this time, the mounting member 70 connected to the first trough beam 31 and the mounting member 70 connected to the secondary beam 50 can be connected and fixed to the adjacent two sides of the photovoltaic module 2000 respectively, so that the photovoltaic support 1000 can be connected and fixed around the photovoltaic module 2000 on the bearing structure 100 by using the mounting member 70, so as to realize the stable assembly of the photovoltaic module 2000 on the photovoltaic support 1000, and further improve the connection stability and reliability between the bearing structure 100 and the photovoltaic module 2000.
[0055] Reference Figure 2 , Figure 3 , Figure 6 and Figure 8 In one embodiment of the utility model, the bearing structure 100 further includes a drainage beam 90, which is connected to the main beam 10 and is disposed near one end of the main beam 10. A drainage groove 91 is disposed on the surface of the drainage beam 90, and a drainage hole 17 connected to the confluence cavity 11 is disposed on the end surface of the main beam 10, and the drainage hole 17 is disposed above the notch of the drainage groove 91.
[0056] In this embodiment, when the bearing structure 100 is provided with multiple main beams 10 to bear and support the water tank frame 30, each main beam 10 can form a confluence cavity 11 to converge and discharge the water of the water tank frame 30. At this time, a drainage beam 90 can be set at one end of the multiple main beams 10, so that the extension direction of the drainage beam 90 is set at an angle to the extension direction of the main beam 10, and then by setting a drainage hole 17 connected to the confluence cavity 11 on the end face of the main beam 10 facing the drainage beam 90, and forming a drainage groove 91 on the surface of the drainage beam 90, the water gathered in the confluence cavity 11 of the main beam 10 can be discharged into the drainage groove 91 through the drainage hole 17, so that the bearing structure 100 can use the drainage groove 91 located on the peripheral side to further gather the water in each main beam 10, so as to better realize the integrated discharge of water from the bearing structure 100, and further improve the drainage stability and reliability of the photovoltaic bracket 1000. Among them, the drainage beam 90 can be connected and fixed to the end of the main beam 10 through a bracket, and the notch of the drainage groove 91 is set close to the drainage hole 17 of the main beam 10, reducing the distance between the drainage beam 90 and the main beam 10, so that the water flow can be more stably concentrated and converged into the drainage groove 91, which is conducive to better avoiding water overflow. When the bearing structure 100 is tilted according to the installation angle of the photovoltaic module 2000, the drainage beam 90 can be set on the side of the bearing structure 100 facing the installation plane of the photovoltaic bracket 1000, so that the water in the confluence cavity 11 of the main beam 10 can flow to the drainage groove 91 more stably under the action of gravity, further improving the drainage stability and reliability of the bearing structure 100.
[0057] Reference Figure 8 In one embodiment of the present invention, the drainage trough 91 has a first inner wall 911 and a second inner wall 913 opposite to each other, the drainage hole 17 is located between the first inner wall 911 and the second inner wall 913, and the second inner wall 913 is arranged close to the surface of the main beam 10 facing away from the water tank frame 30. The drainage beam 90 is defined to have a height direction, and the width of the first inner wall 911 along the height direction is greater than the width of the second inner wall 913 along the height direction.
[0058] In this embodiment, the drainage groove 91 can utilize the first inner wall 911 with a larger width to be set toward the drainage hole 17 of the main beam 10, and the second inner wall 913 with a smaller width can be set below the bottom surface of the main beam 10 facing away from the water groove frame 30, so that the drainage hole 17 of the main beam 10 is located between the first inner wall 911 and the second inner wall 913. At this time, when the water flow in the main beam 10 flows toward the drainage groove 91 through the drainage hole 17, it can flow stably into the drainage groove 91 under the blocking effect of the first inner wall 911, effectively avoiding a certain probability of overflowing the drainage groove 91 when the water flow rate is too fast, preventing water accumulation at the bottom of the photovoltaic bracket 1000, and further improving the drainage stability and reliability of the bearing structure 100.
