Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel support structure technology, and more specifically, to a waterproof photovoltaic bracket. Background Technology

[0002] Against the backdrop of the current global energy transition and sustainable development, photovoltaic (PV) power generation, as a clean and renewable energy source, is receiving increasing attention. PV panels, which convert solar energy into electricity, are widely used on industrial and commercial rooftops, parking shed roofs, and other locations. During installation, PV panels are fixed in place using PV brackets, and multiple panels are spliced ​​together. This combination of panels not only efficiently converts and utilizes energy but also provides shading for the area below.

[0003] Because there are gaps between photovoltaic panels, rainwater can seep through the gaps between adjacent panels to the ground in an environment prone to rain erosion. Traditionally, waterproofing is achieved by sealing the gaps with adhesive strips between adjacent panels. However, these adhesive strips are exposed to the outdoor environment and are subjected to high temperatures for extended periods, which causes them to wear down and makes it difficult to meet the requirements for long-term, stable, and effective waterproofing. Furthermore, disassembling and reinstalling them is quite difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof photovoltaic bracket, which solves the technical problem of how to achieve long-term, stable and effective waterproofing of the gap between adjacent photovoltaic panels.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0006] This utility model provides a waterproof photovoltaic bracket, comprising: a main water tank extending along a first direction, the main water tank including a first main tank portion, a second main tank portion, and a main tank bottom respectively connected to the first main tank portion and the second main tank portion arranged side by side in a second direction, the second direction being perpendicular to the first direction; two main water tank fixing members spaced apart in the second direction, one of the two main water tank fixing members being respectively connected to the first main tank portion and the steel frame, and the other of the two main water tank fixing members being respectively connected to the second main tank portion and the steel frame, so as to fix the main water tank on the steel frame; and a photovoltaic panel fixing member including a first fixing portion and a second fixing portion disposed above the main water tank, the first fixing portion being... The first and second main tanks are respectively connected to the first and second main tanks. Two second fixing parts are provided at intervals in the second direction. The two second fixing parts are respectively connected to the first fixing parts and are used to press two adjacent photovoltaic panels in the second direction onto the first fixing parts. The first gap between two adjacent photovoltaic panels in the second direction is opposite to the main tank, and the width of the first gap is smaller than the width of the main tank. The auxiliary tank extends along the second direction and is pressed onto the main tank by the photovoltaic panels. The auxiliary tank is opposite to the second gap between two adjacent photovoltaic panels in the first direction, and the width of the auxiliary tank is greater than the width of the second gap.

[0007] In some embodiments of this application, the first fixing part is provided with a positioning groove, and the two second fixing parts are arranged in a mirror image. The second fixing part includes a first part, a second part and a third part that are spaced apart in the second direction and respectively connected to one end of the first part and one end of the second part. The third part is connected to the first fixing part, and the other end of the first part is located in the positioning groove. The other end of the second part abuts against the photovoltaic panel and presses the photovoltaic panel onto the first fixing part.

[0008] In some embodiments of this application, the first part and the second part are arranged side by side opposite each other, and the second part of one of the second fixing parts is disposed between the third part of the second fixing part and the second part of the other second fixing part.

[0009] In some embodiments of this application, the first fixing part is provided with a positioning strip, and the positioning strip is disposed between the second portions of the two second fixing parts.

[0010] In some embodiments of this application, both the first main groove and the second main groove are provided with at least two positioning holes, and the positioning holes of each main groove are spaced apart in the first direction; the first fixing part is provided with two mating holes spaced apart in the second direction; the photovoltaic panel fixing component further includes two fasteners, which pass through the two mating holes respectively and are locked to one of the positioning holes on the first main groove and one of the positioning holes on the second main groove, and the first fixing part is connected to the first main groove and the second main groove respectively.

[0011] In some embodiments of this application, the second fixing part is provided with a mounting hole, and the fastener includes a rod part and a cap part connected to each other. The rod part passes through the mounting hole and the mating hole in sequence and is locked in the positioning hole. The cap part presses the second fixing part onto the first fixing part to connect the second fixing part and the first fixing part.

[0012] In some embodiments of this application, the photovoltaic panel fixing component further includes a nut, the rod portion has threads, and the rod portion is screwed to the nut to lock the rod portion in the positioning hole; the second fixing portion is provided with a first stop and a second stop disposed opposite to each other, the first stop and the second stop being used to prevent the cap portion from rotating.

[0013] In some embodiments of this application, the first main tank portion is provided with a first connecting portion, which is located on the purlin of the steel frame; the main water tank fixing member is sleeved on the first connecting portion and the purlin of the steel frame, and the main water tank fixing member includes a connecting member and a locking member. The connecting member includes a first rod portion, a second rod portion and a third rod portion. The first rod portion and the second rod portion are arranged side by side, and the third rod portion is connected to the connecting end of the first rod portion and the connecting end of the second rod portion respectively. The locking member is connected to the free end of the first rod portion and the free end of the second rod portion respectively, and presses the first connecting portion onto the purlin of the steel frame.

[0014] In some embodiments of this application, both the free ends of the first rod and the second rod are provided with external threads. The locking member includes a connecting piece and a locking cap. The connecting piece is provided with two through holes, and the locking cap is provided with internal threads. The free ends of the first rod and the second rod pass through the two through holes respectively and are threadedly connected to the locking cap. The locking cap is used to prevent the free ends of the first rod and the second rod from coming out of the through holes.

[0015] In some embodiments of this application, the two ends of the auxiliary water tank are respectively erected on the first main tank section of one of the two adjacent main water tanks and the second main tank section of the other. The bottom of the auxiliary water tank is provided with a guide plate, which is used to introduce rainwater in the auxiliary water tank into the main water tank.

[0016] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0017] In a waterproof photovoltaic bracket according to an embodiment of this utility model, two main water tank fixing parts are used to establish connections between the first main water tank and the steel frame, and between the second main water tank and the steel frame, so that the main water tank can be stably positioned and fixed on the steel frame. The connection between the first fixing part and the first main water tank, and between the first fixing part and the second main water tank, forms a stable support above the main water tank. The second fixing part presses the photovoltaic panel against the first fixing part, ensuring that the photovoltaic panel can be stably fixed above the main water tank. Thus, this waterproof photovoltaic bracket fixes the photovoltaic panel to the steel frame, and the two second fixing parts are arranged to connect two adjacent photovoltaic panels in the second direction, so that the first gap between the two photovoltaic panels is opposite to the main water tank. On the one hand, since the first gap is opposite to the main water tank and its width is smaller than the width of the main water tank, rainwater leaking from the first gap can fall into the main water tank, flow in the first direction, and eventually drain out. On the other hand, the secondary water tank is pressed tightly against the main water tank by the photovoltaic panels and can be firmly fixed. Since the secondary water tank is opposite to the second gap and its width is larger than the width of the second gap, rainwater leaking from the second gap can fall into the secondary water tank, flow in the second direction, and eventually drain out. Through the synergistic effect of the main and secondary water tanks, the gaps between adjacent photovoltaic panels can be fully covered. This allows the waterproof bracket to not only firmly fix the photovoltaic panels but also effectively prevent water from leaking down through the gaps between adjacent photovoltaic panels and guide drainage. This type of waterproof photovoltaic bracket has strong structural stability, a longer service life than adhesive strips, can meet the needs of long-term, stable, and effective waterproofing, and is easier to maintain.

Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0036] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0037] Please see Figures 1 to 3This utility model provides a waterproof photovoltaic bracket for fixing a photovoltaic panel 6 to a steel frame 5. It mainly includes a main water tank 1, main water tank fixing components 2, photovoltaic panel fixing components 3, and a secondary water tank 4. The main water tank 1 extends along a first direction D1 and includes a first main tank portion 11, a second main tank portion 12, and a main tank bottom 13 connected to the first and second main tank portions 11 and 12 respectively, arranged side-by-side in a second direction D2. The second direction D2 is perpendicular to the first direction D1. Two main water tank fixing components 2 are spaced apart in the second direction D2. One of the two main water tank fixing components 2 is connected to the first main tank portion 11 and the steel frame 5 respectively, and the other of the two main water tank fixing components 2 is connected to the second main tank portion 12 and the steel frame 5 respectively, to fix the main water tank 1 to the steel frame 5. A photovoltaic panel fixing component 3 is disposed above the main water tank 1. The photovoltaic panel fixing component 3 includes a first fixing part 31 and a second fixing part 32. The first fixing part 31 is connected to the first main tank part 11 and the second main tank part 12, respectively. Two second fixing parts 32 are provided at intervals along the second direction D2. The two second fixing parts 32 are respectively connected to the first fixing part 31, and are used to press two adjacent photovoltaic panels 6 along the second direction D2 onto the first fixing part 31, and to make the first gap 63 between the two adjacent photovoltaic panels 6 along the second direction D2 opposite to the main water tank 1, and the width of the first gap 63 is smaller than the width of the main water tank 1. The secondary water tank 4 extends along the second direction D2 and is pressed onto the main water tank 1 by the photovoltaic panels 6. The secondary water tank 4 is opposite to the second gap 64 between two adjacent photovoltaic panels 6 along the first direction D1, and the width of the secondary water tank 4 is larger than the width of the second gap 64.

[0038] In a waterproof photovoltaic bracket according to an embodiment of this utility model, two main water tank fixing parts 2 are used to establish connections between the first main water tank 11 and the steel frame 5, and between the second main water tank 12 and the steel frame 5, so that the main water tank 1 can be stably positioned and fixed on the steel frame 5. Through the connection between the first fixing part 31 and the first main water tank 11 and the first fixing part 31 and the second main water tank 12, a stable support can be formed above the main water tank 1. The second fixing part 32 presses the photovoltaic panel 6 tightly onto the first fixing part 31, thus ensuring that the photovoltaic panel 6 can be stably fixed above the main water tank 1. Therefore, the photovoltaic panel 6 is fixed on the steel frame 5 by this waterproof photovoltaic bracket, and the two second fixing parts 32 are set to connect two adjacent photovoltaic panels 6 in the second direction D2, so that the first gap 63 between the two photovoltaic panels 6 is opposite to the main water tank 1. On the one hand, since the first gap 63 is opposite to the main water tank 1, and the width of the first gap 63 is smaller than the width of the main water tank 1, rainwater leaking from the first gap 63 can fall into the main water tank 1, flow along the first direction D1, and eventually be discharged. On the other hand, the secondary water tank 4 is pressed tightly onto the main water tank 1 by the photovoltaic panel 6, and can be firmly fixed. Since the secondary water tank 4 is opposite to the second gap 64, and the width of the secondary water tank 4 is larger than the width of the second gap 64, rainwater leaking from the second gap 64 can fall into the secondary water tank 4, flow along the second direction D2, and eventually be discharged. Through the synergistic effect of the main water tank 1 and the secondary water tank 4, the gaps between adjacent photovoltaic panels 6 can be fully covered, so that the waterproof bracket can not only firmly fix the photovoltaic panels 6, but also effectively prevent water from leaking down from the gaps between adjacent photovoltaic panels 6, and can guide drainage. This kind of waterproof photovoltaic bracket has strong structural stability, a longer service life than the rubber strip, can meet the needs of long-term, stable, and effective waterproofing, and is easier to maintain.

[0039] It is conceivable that having two second fixing parts 32 pressing against two adjacent photovoltaic panels 6 respectively, compared to having only one second fixing part 32 acting on two adjacent photovoltaic panels 6 simultaneously, can disperse stress and ensure the integrity of the structure and the reliability of the connection. In a specific application scenario, a photovoltaic panel 6 is pressed against the steel frame 5 by two second fixing parts 32 of photovoltaic panel fixing members 3 spaced apart on the second direction D2 on both sides of the second direction D2.

[0040] Please see Figure 4In a specific embodiment, the two ends of the secondary water tank 4 are mounted on the first main tank section 11 of one of the two adjacent main water tanks 1 and the second main tank section 12 of the other. The bottom 43 of the secondary water tank 4 is equipped with guide vanes 431, which guide rainwater from the secondary water tank 4 into the main water tank 1. In specific usage scenarios, the main water tank 1 is arranged at an angle, and the secondary water tank 4 is arranged horizontally. Guiding rainwater from the secondary water tank 4 into the main water tank 1 and discharging it along the main water tank 1 reduces water accumulation in the secondary water tank 4 and accelerates overall drainage efficiency. The guide vanes 431 also prevent rainwater from flowing back and seeping under a waterproof photovoltaic support, further improving drainage efficiency.

[0041] In this embodiment, the secondary water tank 4 includes a first secondary tank portion 41, a second secondary tank portion 42, and a tank bottom 43 that are spaced apart along a first direction D1 and connected to the first secondary tank portion 41 and the second secondary tank portion 42, respectively. The first secondary tank portion 41 includes a main body portion 411 and a folded edge portion 412. The main body portion 411 is connected to the tank bottom 43 and the folded edge portion 412, respectively, and the folded edge portion 412 extends towards the side closer to the second secondary tank portion 42. Since the secondary water tank 4 corresponds to and matches the main water tank 1, and the main water tank 1 is arranged at an incline, the first secondary tank portion 41 is located at a lower position on the incline line, and the second secondary tank portion 42 is located at a higher position on the incline line. The folded edge portion 412 of the first secondary tank portion 41 can prevent rainwater from overflowing or splashing from the secondary water tank 4.

[0042] Please see Figure 3 The first fixing part 31 is provided with a positioning groove 311, and the two second fixing parts 32 are arranged in a mirror image. The second fixing part 32 includes a first part 321, a second part 322 and a third part 323 that are spaced apart in the second direction D2 and respectively connected to one end of the first part 321 and one end of the second part 322. The third part 323 is connected to the first fixing part 31, and the other end of the first part 321 is located in the positioning groove 311. The other end of the second part 322 presses against the photovoltaic panel 6 and presses the photovoltaic panel 6 tightly onto the first fixing part 31. The first part 321 of the second fixing part 32 is used to cooperate with the positioning groove 311. On the one hand, it can ensure the accuracy during installation, and on the other hand, it can limit the overall horizontal displacement of the second fixing part 32. The second part 322 is used to press against the photovoltaic panel 6, and the third part 323 is used to connect with the first fixing part 31. The design of the three parts can enhance the stability of the cooperation between the second fixing part 32, the first fixing part 31 and the photovoltaic panel 6. The two second fixing parts 32 are arranged in a mirror image. The second parts 322 of the two second fixing parts 32 can press the two adjacent photovoltaic panels 6 onto the first fixing part 31 from opposite sides.

[0043] Please see Figures 1 to 3In a specific embodiment, the first part 321 and the second part 322 are arranged side by side and opposite to each other, and the second part 322 of one of the second fixing parts 32 is located between the third part 323 of the second fixing part 32 and the second part 322 of the other second fixing part 32.

[0044] In a specific application scenario, the photovoltaic panel 6 includes a frame 61 and a panel 62. The panel 62 is located inside the frame 61 and is laid on top of the frame 61. A groove 611 with an inward opening is formed between the top and bottom of the frame 61. The second fixing part 32 enters the frame 61, and the second part 322 extends into the groove 611. The other end of the second part 322 presses against the bottom of the frame 61, thereby pressing the photovoltaic panel 6 onto the first fixing part 31. It can be imagined that the grooves 611 on the adjacent sides of two adjacent photovoltaic panels 6 face opposite directions. The second parts 322 of the two second fixing parts 32 are adjacent to each other and can extend into the grooves 611 on the adjacent sides of two adjacent photovoltaic panels 6 from opposite sides, thereby fixing the two adjacent photovoltaic panels 6. The second fixing part 32 is located inside the frame 61 of the photovoltaic panel 6, and is not easily affected by external forces and will not be dislodged from its original position. Moreover, the structure is more compact and aesthetically pleasing.

[0045] In other embodiments, the first part 321 and the second part 322 are not arranged side by side. The first part 321 of one second fixing part 32 is located between the third part 323 of the second fixing part 32 and the first part 321 of the other second fixing part 32. The two second fixing parts 32 are located within the first gap 63, and the other end of the second part 322 abuts against the top of the frame 61. In this embodiment, the second parts 322 of the two second fixing parts 32 are opposite to each other and abut against the top of the frame 61, which is not conducive to resisting external forces and affects the compactness and aesthetics of the overall structure. The two second fixing parts 32 are located within the first gap 63, and the size of the first gap 63 and the main water tank 1 opposite to it must be enlarged accordingly. On the one hand, this increases the material cost of the main water tank 1. On the other hand, within the limited space, the enlargement of the first gap 63 will inevitably reduce the number of photovoltaic panels 6 that can be laid on the top of the steel frame 5, affecting the efficiency of energy conversion and utilization.

[0046] Please see Figure 3 The first fixing part 31 is provided with a positioning strip 312, and the positioning strip 312 is located between the second parts 322 of the two second fixing parts 32. The positioning strip 312 is used to position the side of the frame 61 of the photovoltaic panel 6. The positioning strip 312 and the second part 322 form a cooperation to limit the offset of the photovoltaic panel 6 in the second direction D2, thereby improving the accuracy of the installation of the photovoltaic panel 6.

[0047] In a specific embodiment, each of the first main groove portion 11 and the second main groove portion 12 is provided with at least two positioning holes, and the positioning holes of each main groove portion are spaced apart in the first direction D1. The first fixing portion 31 is provided with two mating holes spaced apart in the second direction D2. The photovoltaic panel fixing component 3 also includes two fasteners 7, which pass through the two mating holes respectively and are locked in one of the positioning holes on the first main groove portion 11 and one of the positioning holes on the second main groove portion 12, respectively, so that the first fixing portion 31 is connected to the first main groove portion 11 and the second main groove portion 12 respectively. When fixing photovoltaic panels 6 of different sizes or when the position of photovoltaic panels 6 needs to be adjusted, the mating holes can be switched to align with different positioning holes, and then the fasteners 7 can be locked in the specific positioning holes, which enhances the applicability of this waterproof photovoltaic bracket.

[0048] In a specific embodiment, the second fixing part 32 is provided with a mounting hole, and the fastener 7 includes a rod part 71 and a cap part 72 connected to each other. The rod part 71 passes through the mounting hole and the mating hole in sequence and is locked in the positioning hole. The cap part 72 presses the second fixing part 32 onto the first fixing part 31 to connect the second fixing part 32 and the first fixing part 31. A reliable connection between the first fixing part 31 and the main water tank 1 and between the second fixing part 32 and the first fixing part 31 can be quickly and easily achieved with a single fastener 7, reducing the complexity of the overall structure.

[0049] In a further embodiment, the photovoltaic panel fixing member 3 also includes a nut (not shown in the figures), and the rod portion 71 has threads and is screwed to the nut so that the rod portion 71 is locked in the positioning hole. The second fixing part 32 is provided with a first stop 324 and a second stop 325 disposed opposite to each other, the first stop 324 and the second stop 325 being used to prevent the cap portion 72 from rotating.

[0050] The second fixing part 32, the first fixing part 31, and the first main groove part 11, or the second fixing part 32, the first fixing part 31, and the second main groove part 12, are sequentially clamped between the cap part 72 and the nut, achieving effective connection between each pair of the three. This screw-on connection is simple to assemble. Specifically, during installation or disassembly, relative rotation between the nut and the rod part 71 is required. Since the first stop 324 and the second stop 325 prevent the cap part 72 from rotating, the rod part 71 can remain stationary. The operator only needs to rotate the nut; no additional fasteners 7 are required, making operation convenient. Furthermore, the operator can operate from below the steel frame 5, improving construction safety. In this embodiment, the first stop 324 and the second stop 325 are located on the third part 323 of the second fixing part 32.

[0051] Please see Figures 1 to 5The first main tank section 11 is provided with a first connecting part 111, which is located on the purlin 51 of the steel frame 5. The main tank fixing member 2 is sleeved on the first connecting part 111 and the purlin 51 of the steel frame 5. The main tank fixing member 2 includes a connecting member 21 and a locking member 22. The connecting member 21 includes a first rod 211, a second rod 212, and a third rod 213. The first rod 211 and the second rod 212 are arranged side by side. The third rod 213 is connected to the connecting end of the first rod 211 and the connecting end of the second rod 212, respectively. The locking member 22 is connected to the free end of the first rod 211 and the free end of the second rod 212, respectively, and presses the first connecting part 111 tightly onto the purlin 51 of the steel frame 5. The second main tank section 12 is provided with a second connecting part. The cooperation between the second connecting part, the purlin 51, and the other main tank fixing member 2 is described above and will not be repeated here.

[0052] The connector 21 forms a U-shaped structure that can tightly wrap around the purlin 51 of the steel frame 5, increasing the contact area and friction, thereby improving the stability of the connection. The cooperation between the connector 21 and the locking member 22 forms a stable connection structure. The main water tank fixing member 2 presses the first connecting part 111 and the second connecting part onto the purlin 51, thereby stably fixing the main water tank 1 onto the steel frame 5.

[0053] Please see Figure 3 and Figure 5 In a further embodiment, both the free ends of the first rod portion 211 and the free ends of the second rod portion 212 are provided with external threads. The locking member 22 includes a connecting piece 221 and a locking cap 222. The connecting piece 221 is provided with two through holes, and the locking cap 222 is provided with internal threads. The free ends of the first rod portion 211 and the free ends of the second rod portion 212 pass through the two through holes respectively and are threadedly connected to the locking cap 222. The locking cap 222 is used to prevent the free ends of the first rod portion 211 and the free ends of the second rod portion 212 from dislodging from the through holes. The connecting piece 221 is used to connect the first rod 211 and the second rod 212. The connecting part and the connecting piece 21 form a closed frame shape, which can fully cover the purlin 51 of the steel frame 5, thereby further improving the stability of the connection. Through the screw connection between the first rod 211 and the locking cap 222 and between the second rod 212 and the locking cap 222, a firm connection between the locking piece 22 and the connecting piece 21 is achieved. The screw connection method has the characteristics of stable connection and easy installation. While improving the reliability of the connection, it reduces the installation difficulty and cost.

[0054] In this embodiment, the connecting piece 221 is located below the purlin 51 of the steel frame 5, and the third rod 213 presses against the first connecting part 111. On the one hand, this ensures that the first connecting part 111 is stably pressed, and on the other hand, it facilitates the operation of the operator from below the steel frame 5, thereby improving the safety of construction.

[0055] Please see Figures 2 to 5 In a specific embodiment, the first main tank portion 11 is provided with at least two positioning holes, which are spaced apart in the first direction D1. The first connecting portion 111 is provided with an assembly hole, and the main water tank 1 also includes a positioning member 8. The positioning member 8 passes through one of the positioning holes of the first main tank portion 11 and is locked in the assembly hole of the first connecting portion 111 to connect the first connecting portion 111 and the first main tank portion 11. This allows the position of the first connecting portion 111 to be adjusted according to the specific structure of the steel frame 5 and the position of the purlin 51, making it easier for the first main tank portion 11 to be fixed on the steel frame 5.

[0056] In this embodiment, the assembly hole of the first connecting part 111 is aligned with one of the positioning holes, and the mating hole of the first fixing part 31 is aligned with the other positioning hole, so that the two sets of connections, namely the main water tank 1 being fixed on the steel frame 5 by the main water tank fixing member 2 and the photovoltaic panel 6 being fixed on the main water tank 1 by the photovoltaic panel fixing member 3, do not conflict with each other.

[0057] It should be noted that the connection between the second connecting part and the main water tank fixing part 2, as well as the connection between the second connecting part and the second main tank part 12, are specifically the same as the connection of the first connecting part 111 in the above embodiment, and will not be described in detail here.

[0058] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
