Description

Technical Field

[0001] The utility model relates to the field of optoelectronic technology, in particular to a lap joint structure for photovoltaic panels. Background Art

[0002] The overlap structure of photovoltaic panels refers to the system installed between photovoltaic panels to support and connect photovoltaic panels. These structures play the role of supporting, fixing and protecting photovoltaic panels, and also affect the performance, safety and life of the photovoltaic system. With the continuous development of the solar energy industry, the design and application of photovoltaic panel installation structures will also be continuously optimized and improved.

[0003] The structures currently used for overlapping photovoltaic panels on the market are generally: brackets or support frames, which are used to support photovoltaic panels and install them on the ground or roof. The brackets can be simple frame structures made of metal or plastic. The appropriate type and size can be selected according to the conditions of the installation site; beams or transverse supports, which are installed on the brackets or support frames to support the bottom of the photovoltaic panels. These beams can be simple metal pipes or steel, which can be fixed and adjusted as needed; fixing clamps, which are used to fix the photovoltaic panels to the support frames or beams. The fixing clamps are usually made of metal and can be U-shaped or L-shaped in design. The photovoltaic panels are securely fixed to the supporting structure by bolts or clamps.

[0004] The overlapping structures currently used for photovoltaic panels on the market are not easy to install because the bolt installation points between the brackets are not convenient. Therefore, workers need to determine the position in advance during installation. After the brackets are fixed as a whole, they will be placed in the place where the photovoltaic panels need to be installed. This requires very rich installation experience. Otherwise, multiple rework and adjustments will be required due to position deviations between the brackets, which will greatly reduce the installation efficiency. In addition, due to frequent disassembly, the stability between the brackets will also be reduced, increasing the risk for subsequent use. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a lap joint structure for photovoltaic panels to solve the technical problem of low installation efficiency of traditional structures.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lap joint structure for photovoltaic panels, comprising a support plate, wherein first bolt groups are movably penetrated at the corners at both ends of the support plate, and the corners of the support plate are fixed with special-shaped bases through corresponding first bolt groups, and the support surface of each special-shaped base is in contact with the bottom surface of the support plate, and self-tapping screws are threadedly penetrated at the bottom of each two special-shaped bases located on the same side of the support plate toward the side away from the other special-shaped bases, and each two special-shaped bases located on the same side of the support plate are threadedly connected with V-shaped water grooves through corresponding self-tapping screws, and both sides of the bottom surface of the support plate are in contact with one side of the corresponding top surface of the V-shaped water groove, and water leakage arc surfaces are provided on both sides of the support plate, and each water leakage arc surface cooperates with the corresponding V-shaped water groove.

[0007] By adopting the above technical solution, the V-shaped gutter can be installed first during installation, because there is no need to fix the nut in the V-shaped gutter when installing the support plate. First, the special-shaped base and the support plate are fixed by the first bolt group. Then, after determining the position of the support plate according to the on-site environment, the special-shaped base and the V-shaped gutter are fixed by self-tapping screws. Because compared with the traditional side pressure base, the special-shaped base changes the connection point with the support plate to the side, and changes the vertical force applied by the support plate to the special-shaped base to the support surface of the special-shaped base. In this way, when the surrounding support plates are damaged due to age or force at the connection point, the support plate cannot escape the restriction of the first bolt group, thereby increasing the bearing capacity of the connection point. Therefore, the connection between the special-shaped base and the V-shaped gutter does not need to withstand excessive horizontal force, so no nuts are required for anti-falling insurance, and only self-tapping screws are required.

[0008] The utility model is further configured such that the top ends of the two V-shaped water tanks are slidably sleeved with a plurality of cross arms, and each cross arm does not interfere with the corresponding support plate, and both sides of the two V-shaped water tanks are provided with limited sliding grooves below the self-tapping screws, and both sides of the inner wall of each cross arm are connected with support blocks located inside the limited sliding grooves, and a fixing nut is placed inside each support block, and both sides of each cross arm are movably penetrated by hexagon socket bolts threadedly connected to the fixing nuts, and each cross arm is fixed to the corresponding V-shaped water tank by corresponding fixing nuts and hexagon socket bolts.

[0009] By adopting the above technical solution, after the V-shaped water tank is installed, the fixing nut is placed in the support block, and after the hexagon socket bolt is screwed on, the cross arm is pushed in along the limiting slide groove. After the position of the cross arm is determined, the support block and the limiting slide groove cooperate to prevent the fixing nut from rotating freely. At this time, the hexagon socket bolt is tightened to fix the cross arm.

[0010] The utility model is further configured such that a second bolt group is movably penetrated through the center of the top surface of each cross arm, and a medium-pressure block is fixed to each cross arm through the corresponding second bolt group. The bottom surface of the medium-pressure block on the same vertical plane facing the support plate cooperates with the corresponding cross arm top surface facing the support plate and the corresponding top surface of the support plate to fix the photovoltaic panel.

[0011] By adopting the above technical solution, after the photovoltaic panel is fixed, the medium-pressure block is fixed to the cross arm through the second bolt group to complete the further fixation of the photovoltaic panel.

[0012] The utility model is further configured such that oblique blocks are provided on both sides of the inner wall of each of the medium-pressure blocks, the oblique blocks inside the medium-pressure blocks located on the same vertical plane all contact the limiting plate together, and the bottom surface of each limiting plate is connected with a clamping block, the top surfaces of the limiting plates inside every two medium-pressure blocks located on the same vertical plane are commonly connected with a waterproof cover plate, and the clamping blocks inside every two medium-pressure blocks located on the same vertical plane cooperate with the oblique blocks in the corresponding medium-pressure block through the corresponding limiting plate and the corresponding waterproof cover plate.

[0013] By adopting the above technical solution, after the medium-pressure block is fixed, the waterproof cover plate is aligned with the middle of the medium-pressure block and pressed down. At this time, under the restriction of the inclined block, the limit plate is deformed and bent inward, and the waterproof cover plate is continued to be pressed down until the block contacts the vertical surface of the inclined block, and the limit plate is reset. At this time, the waterproof cover plate is fixed on the medium-pressure block.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model installs the V-shaped water tank first during installation, because there is no need to fix the nut in the V-shaped water tank. After the V-shaped water tank is installed, the fixing nut is placed in the support block, and the hexagon socket bolt is screwed on, and the cross arm is pushed in along the limiting slide groove. After the position of the cross arm is determined, the support block and the limiting slide groove are matched, so that the fixing nut cannot rotate freely. At this time, the hexagon socket bolt is tightened to fix the cross arm, and the special-shaped base is fixed to the support plate by the first bolt group. Then, after the position of the support plate is determined according to the on-site environment, the special-shaped base is fixed to the V-shaped water tank by self-tapping screws. Compared with the traditional side pressure base, the special-shaped base is connected with the support plate. The connection point is changed to the side, which increases the bearing capacity of the connection point. Therefore, the connection between the special-shaped base and the V-shaped water tank does not need to withstand excessive horizontal force, and only self-tapping screws are needed. After the photovoltaic panel is fixed, the medium-pressure block is fixed to the cross arm through the second bolt group to complete the further fixation of the photovoltaic panel. After the medium-pressure block is fixed, the waterproof cover is aligned with the middle of the medium-pressure block and pressed down. At this time, under the restriction of the inclined block, the limit plate is deformed and bent inward, and the waterproof cover continues to be pressed down until the block contacts the vertical surface of the inclined block, and the limit plate is reset. At this time, the waterproof cover is fixed on the medium-pressure block. In this way, the installation does not require repeated adjustments and the installation is very quick.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A lap joint structure for photovoltaic panels, such as Figure 1-7 As shown, it includes a support plate 1, and the corners at both ends of the support plate 1 are movably penetrated by first bolt groups 15, and the corners of the support plate 1 are fixed with special-shaped bases 17 through the corresponding first bolt groups 15, and the supporting surface of each special-shaped base 17 is in contact with the bottom surface of the support plate 1, and each two special-shaped bases 17 located on the same side of the support plate 1 are threadedly penetrated by self-tapping screws 5 on the side away from the other special-shaped bases 17. Each two special-shaped bases 17 located on the same side of the support plate 1 are threadedly connected with V-shaped water tanks 3 through corresponding self-tapping screws 5, and both sides of the bottom surface of the support plate 1 are in contact with one side of the top surface of the corresponding V-shaped water tank 3. Water leakage arc surfaces 2 are provided on both sides of the support plate 1, and each water leakage arc surface 2 cooperates with the corresponding V-shaped water tank 3. When installing, the V-shaped water tank 3 can be installed first, because it is not necessary to install the support plate 1 when installing the support plate 1. The nut 7 is fixed in the V-shaped water tank 3, and the special-shaped base 17 and the support plate 1 are first fixed by the first bolt group 15. Then, after the position of the support plate 1 is determined according to the on-site environment, the special-shaped base 17 and the V-shaped water tank 3 are fixed by the self-tapping screws 5. Because compared with the traditional side-pressure base, the special-shaped base 17 changes the connection point with the support plate 1 to the side, and the vertical force applied by the support plate 1 to the special-shaped base 17 is changed to be borne by the supporting surface of the special-shaped base 17. In this way, when the surrounding support plates 1 are damaged due to age or force at the connection point, the support plate 1 cannot escape the restriction of the first bolt group 15, thereby increasing the bearing capacity of the connection point. Therefore, the connection between the special-shaped base 17 and the V-shaped water tank 3 does not need to withstand excessive horizontal force, so no nut is required for anti-falling insurance, and only self-tapping screws 5 are required.

[0027] The tops of the two V-shaped water tanks 3 are both slidably sleeved with a plurality of cross arms 8, and each cross arm 8 does not interfere with the corresponding support plate 1. Both sides of the two V-shaped water tanks 3 are located below the self-tapping screws 5 and a limited sliding groove 4 is provided. Both sides of the inner wall of each cross arm 8 are connected with a support block 9 located inside the limited sliding groove 4, and a fixing nut 7 is placed inside each support block 9. Both sides of each cross arm 8 are movably penetrated by a hexagon socket bolt 6 threadedly connected to the fixing nut 7. Each cross arm 8 is fixed to the corresponding V-shaped water tank 3 by the corresponding fixing nut 7 and the hexagon socket bolt 6. After the V-shaped water tank 3 is installed, the fixing nut 7 is placed in the support block 9, and after the hexagon socket bolt 6 is screwed on, the cross arm 8 is pushed in along the limited sliding groove 4. After the position of the cross arm 8 is determined, the support block 9 cooperates with the limited sliding groove 4, so that the fixing nut 7 cannot rotate freely. At this time, the hexagon socket bolt 6 is tightened to fix the cross arm 8.

[0028] The center of the top surface of each cross arm 8 is movably penetrated by a second bolt group 16, and each cross arm 8 is fixed with a medium-pressure block 14 through the corresponding second bolt group 16. The bottom surface of the medium-pressure block 14 on the same vertical plane facing the side of the support plate 1 cooperates with the side of the corresponding cross arm 8 top surface facing the support plate 1 and the top surface of the corresponding support plate 1 to fix the photovoltaic panel. After the photovoltaic panel is fixed, the medium-pressure block 14 is fixed to the cross arm 8 by the second bolt group 16 to complete the further fixation of the photovoltaic panel. Both sides of the inner wall of each medium-pressure block 14 are provided with inclined blocks 13, and the inclined blocks 13 inside the medium-pressure blocks 14 on the same vertical plane all contact the limiting plate 11 together, and the bottom surface of each limiting plate 11 They are all connected with a clamping block 12, and the top surfaces of the limiting plates 11 inside every two medium-pressure blocks 14 located on the same vertical plane are commonly connected with a waterproof cover plate 10. The clamping blocks 12 inside every two medium-pressure blocks 14 located on the same vertical plane cooperate with the corresponding inclined blocks 13 in the corresponding medium-pressure blocks 14 through the corresponding limiting plates 11 and the corresponding waterproof cover plates 10. After the medium-pressure blocks 14 are fixed, the waterproof cover plate 10 is aligned with the middle of the medium-pressure blocks 14 and pressed down. At this time, under the restriction of the inclined block 13, the limiting plate 11 is deformed and bent inward, and the waterproof cover plate 10 is continued to be pressed down until the clamping block 12 contacts the vertical surface of the inclined block 13, and the limiting plate 11 is reset. At this time, the waterproof cover plate 10 is fixed on the medium-pressure blocks 14.

[0029] Working principle: When installing, first install the V-shaped water tank 3, because there is no need to fix the nut 7 in the V-shaped water tank 3. After the V-shaped water tank 3 is installed, place the fixing nut 7 in the support block 9, screw on the hexagon socket bolt 6, and push the cross arm 8 along the limiting slide groove 4. After determining the position of the cross arm 8, the support block 9 cooperates with the limiting slide groove 4, so that the fixing nut 7 cannot rotate freely. At this time, tighten the hexagon socket bolt 6 to fix the cross arm 8, fix the special-shaped base 17 to the support plate 1 through the first bolt group 15, and then determine the position of the support plate 1 according to the on-site environment, and fix the special-shaped base 17 to the V-shaped water tank 3 through the self-tapping screw 5. Because compared with the traditional side pressure base, the special-shaped base 17 changes the connection point with the support plate 1 to the side, and changes the vertical force applied by the support plate 1 to the special-shaped base 17 to the support surface of the special-shaped base 17. In this way, when the surrounding support plates 1 are damaged due to age or force at the connection point, The support plate 1 cannot be separated from the restriction of the first bolt group 15, which increases the bearing capacity of the connection point. Therefore, the connection between the special-shaped base 17 and the V-shaped gutter 3 does not need to withstand excessive horizontal forces. Therefore, no nuts are required for anti-falling insurance, and only self-tapping screws 5 are required. After the installation is completed, in rainy weather, rainwater will be discharged along the leaking arc surface 2 into the V-shaped gutter 3 to prevent water accumulation. After the photovoltaic panel is fixed, the medium-pressure pressing block 14 is fixed to the cross arm 8 by the second bolt group 16 to complete the further fixation of the photovoltaic panel. After the medium-pressure pressing block 14 is fixed, the waterproof cover plate 10 is aligned with the middle of the medium-pressure pressing block 14 and pressed down. At this time, under the restriction of the inclined block 13, the limit plate 11 is deformed and bent inwardly, and the waterproof cover plate 10 is continued to be pressed down until the block 12 contacts the vertical surface of the inclined block 13, and the limit plate 11 is reset. At this time, the waterproof cover plate 10 is fixed on the medium-pressure pressing block 14, so that the installation does not need to be repeatedly adjusted, and the installation is very fast.

[0030] On the basis of the above structure, in this embodiment, although the embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
