Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, in particular to a color steel tile roof connector for a solar photovoltaic panel. Background Art

[0002] Solar energy is a clean, renewable energy source that is easy to use for a long time. As traditional energy becomes increasingly scarce, people are paying more and more attention to the development of solar energy resources. In addition to setting up large-scale solar photovoltaic panel arrays in suitable open wasteland, there is also a type of photovoltaic panels installed on the roofs of buildings to supply photovoltaic components for use in homes, factories or communities. The roofs of these buildings are generally colored steel tiles, and the photovoltaic panels are connected to the colored steel tile roofs through fixed brackets.

[0003] Color steel tiles are generally divided into trapezoidal tiles and corner tiles. The connection structure of the trapezoidal tiles usually includes two fixedly connected clips, which are clamped on both sides of the tiles, and the clips are fixed to the tiles by screws. For example, the Chinese patent with application number 201120071852.1 discloses a bite-type corrugated sandwich panel roof photovoltaic support system, which includes a connecting seat and side seats on both sides of the connecting seat. The side seats are provided with trapezoidal grooves, and the side seats are provided with a number of clamps for connecting color steel tiles. The clamps are provided with connecting holes. The clamps pass through the connecting holes and the color steel tiles by bolts, and then the bite-type corrugated sandwich panel roof photovoltaic support system is fixed to the color steel tiles as a whole; another example is an integrated point-distribution solar support disclosed in the Chinese patent with application number 201420432431.0, which includes a color steel tile clamp, and the color steel tile clamp includes a circular frame, and two clips are provided at the bottom of the circular frame; the upper ends of the two clips are respectively fixed to the circular frame. The two sides of the frame are outwardly expanded at the lower end, and a waterproof asphalt pad is provided between the clip and the ridge of the color steel tile; for example, a Chinese patent with application number 201510117222.6 discloses a trapezoidal color steel tile roof photovoltaic module installation structure, including a trapezoidal mounting seat, a disc-type self-drilling screw, a waterproof rubber pad and a foam tape. The trapezoidal mounting seat is fixed to the crest of the trapezoidal color steel tile roof by the disc-type self-drilling screw. The contact surface between the trapezoidal mounting seat and the trapezoidal color steel tile roof is provided with a foam tape to prevent the disc-type self-drilling screw from loosening due to thermal expansion and contraction of the material. A waterproof rubber pad is installed on the inner side of the disc position of the disc-type self-drilling screw, and the waterproof rubber pad is tightly pressed against the boss at the disc-type self-drilling screw installation hole of the trapezoidal mounting seat.

[0004] In the above-mentioned connection structures, the clips of the clamps are fixed. When encountering trapezoidal tiles of different sizes, clamps of corresponding sizes need to be matched. In other words, it is impossible to provide a universal clamp, which causes a significant increase in cost. In addition, the screws that fix the clips to the trapezoidal tiles are in an exposed state, which can easily cause water ingress, rust, and side leakage.

[0005] In addition, in order to facilitate the fixation of the clamp and the solar panel, the applicant has designed a connector, such as a color steel tile roof connector for a solar photovoltaic panel disclosed in Chinese patent application number 201620348505.1, which includes a base located below and a support connected to the top of the base, the support can enable the solar photovoltaic panel to move up and down relative to the base, the support includes a support rod, the lower part of the support rod is connected to the base, the axis of the support rod is arranged up and down and can rotate around its own axis, the upper part of the support rod is threadedly connected to the first clamp, and the upper part of the first clamp is connected to a support that can move up and down relative to the first clamp The second clamp comprises a first plane located below and a second plane located above the first plane and spaced apart, the first plane is provided with a first threaded hole matching the outer diameter of the support rod and threadedly connected to the support rod, a second threaded hole having an inner diameter larger than the first threaded hole is provided at a position corresponding to the first threaded hole on the second plane, the second threaded hole is connected to the second clamp, the second clamp comprises a middle plane arranged opposite to the second plane, the middle plane is provided with a connecting hole matching the second threaded hole, a connecting screw is inserted from the connecting hole and threadedly connected to the second threaded hole to connect the second clamp to the first clamp.

[0006] However, the connection method between the two clamps mentioned above requires processing two holes arranged at intervals on the second clamp, which is complicated and wastes profiles. In addition, the number of teeth matching between the thread and the clamp is small, which is prone to shaking. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a universal color steel tile roof connector for solar photovoltaic panels of different sizes in view of the problems existing in the above-mentioned prior art.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a color steel tile roof connecting piece for a solar photovoltaic panel, comprising a base for fixedly connecting to the color steel tile roof, and a support located above the base and capable of fixedly connecting to the solar photovoltaic panel, the base comprising a main body, and two clamping plates arranged on the main body for clamping the edges on the color steel tile roof from both sides, characterized in that: at least two accommodating grooves arranged in parallel and spaced apart in the transverse direction are formed at the bottom of the main body, each clamping plate comprising a clamping portion, and a connecting portion that can be connected to the accommodating groove and thereby enables the clamping plate to rotate longitudinally relative to the main body.

[0009] To facilitate the installation of the splint and the main body, an opening is formed at the bottom of the receiving groove, and both ends of the receiving groove in the length direction pass through the main body. The thickness of the clamping part is not greater than the width of the opening. The connecting part is inserted into the receiving groove and can rotate relative to the receiving groove, and its position in the length direction of the receiving groove is relatively fixed.

[0010] In order to position the connecting part relative to the accommodating groove in the length direction, the base also includes rivets, which are inserted from both ends of the connecting part respectively, so that the tail of the rivet inserted in the connecting part abuts and locks with the inner wall of the connecting part, and the head size of the rivet is larger than the size of the accommodating groove.

[0011] To ensure that the two clamps can remain parallel to the sides of the edge at the same time, the base also includes a gear, which is set on one of the rivets of each connecting part and can rotate synchronously with the rivet. The gears on the two connecting parts are meshed with each other to make the two clamps rotate synchronously.

[0012] In order to facilitate the fixation of the clamping plate and the edge and avoid water leakage, screw holes are opened on the clamping part of the clamping plate, and the clamping part and the edge are connected and fixed by screws. The base also includes a waterproof component for covering the screw holes and screws.

[0013] In order to prevent the fixing screws from being washed by water and rusting, and to prevent water from leaking from the side of the screw hole into the bottom of the edge, the waterproof component includes a waterproof cover, and a first baffle extending upward is provided at the bottom of the side of the clamping part away from the edge, and a second baffle extending upward is provided in the middle, and the waterproof cover abuts between the first baffle and the second baffle.

[0014] In order to ensure that the forces on both sides of the waterproof cover are balanced and to prevent one side from tilting up and separating from the clamping plate, the top of the first baffle is bent toward the second baffle, and the top of the second baffle is bent toward the first baffle. A first plug-in portion is extended from one side of the waterproof cover close to the first baffle, and the first plug-in portion is inserted under the bent portion of the top of the first baffle and has an interference fit with the first baffle. A second plug-in portion is bent from one side of the waterproof cover close to the second baffle, and the second plug-in portion is inserted under the bent portion of the top of the second baffle and abuts against the second baffle.

[0015] To further enhance the sealing performance, the waterproof component also includes an upper sealing gasket. Each clamping portion is located between the first baffle plate and the second baffle plate and is provided with a downwardly recessed positioning groove. The upper sealing gasket is placed in the positioning groove. The waterproof cover is located above the upper sealing gasket and is tightly pressed against the upper sealing gasket.

[0016] In order to enhance the stability of the support connection, the support includes a first clamp, a second clamp located below the first clamp, and an adjustment seat connected to the base. The first clamp and the second clamp, and the second clamp and the adjustment seat are connected through a support assembly. The support assembly includes a screw with internal and external double threads, and a first adjusting bolt with external threads connecting the screw and the adjustment seat. The screw is at least threadedly matched with the second clamp to connect the first clamp and the second clamp. A threaded hole is opened in the screw, and the first adjusting bolt is threadedly matched with the base and the threaded hole respectively.

[0017] In order to facilitate the lateral adjustment of the support relative to the base, the top of the base body is provided with a downwardly recessed slide groove, and the adjustment seat is provided with a second adjustment bolt that can be inserted into the slide groove to form a sliding connection.

[0018] Compared with the prior art, the advantages of the present invention are: by configuring the base to include a main body and two clamping plates that can rotate relative to the main body, and the spacing between the two clamping plates can be adjusted, the clamping plates are suitable for almost all existing color steel tiles, thereby improving the versatility of the connecting parts and reducing costs; the two clamping plates are connected by gear meshing so that the two clamping plates can rotate synchronously, thereby ensuring that the two clamping plates remain parallel to the sides of the edges of the color steel tiles at the same time, so as to facilitate connection and fixation; by providing a waterproof cover with balanced force, rusting of the screws fixing the clamping plates and the edges and side leakage at the connection position are avoided; by providing a double-threaded screw, the processing procedures of the support clamp are reduced and the stability of the thread fit is improved.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1 to Figure 3 A color steel tile roof connector for a solar photovoltaic panel includes a base 1 fixedly connected to the color steel tile roof, and a support 2 located above the base 1 and fixedly connected to the solar photovoltaic panel. The support 2 is arranged above the base 1 and can move up and down relative to the base 1. In this embodiment, the color steel tile is a trapezoidal tile.

[0027] The base 1 includes a body 11 and two clamping plates 12 arranged on the body 11 for clamping the edges 100 on the color steel tile roof from both sides. A downwardly concave slide groove 111 is formed on the top of the body 11, and the top surface of the slide groove 111 is open for sliding with the support 2; at least two accommodating grooves 112 are formed on the bottom of the body 11 and are arranged in parallel and spaced apart in the horizontal direction. The bottom of the accommodating groove 112 is formed with an opening 1121. The slide groove 111 and the accommodating groove 112 extend in the same direction, from Figure 1 The two ends of the receiving groove 112 in the length direction pass through the body 11 so as to be connected with the clamping plate 12. In this embodiment, there are four receiving grooves 112 arranged in parallel and spaced apart, so as to be adapted to almost all sizes of trapezoidal tiles.

[0028] The receiving groove 112 is generally cylindrical, and its two ends in the axial direction pass through the body 11. The opening 1121 at the bottom of the receiving groove 112 is located on the cylindrical peripheral wall. The central angle between the two ends of the opening 1121 is approximately 25°, that is, when each clamping plate 12 is installed in the receiving groove 112, the rotation angle relative to the receiving groove 112 in the longitudinal direction is 25°, and the total rotation angle between the two clamping plates 12 is 50° to 100°. Since the inclination angle of the trapezoidal tile is usually between 58.5° and 97.2°, the above rotation angle can basically apply to all trapezoidal tiles.

[0029] Each clamping plate 12 includes a clamping portion 121 and a connecting portion 122 disposed on the top of the clamping portion 121. At least one side of the clamping portion 121 is in the shape of a flat plate. When installed, the flat side faces the other clamping plate 12 so as to be parallel to the side of the edge 100 clamped between the two clamping plates 12. The connecting portion 122 is in a shape that matches the receiving groove 112. In this embodiment, it is cylindrical, and the connecting portion 122 is also hollow, with both ends in the length direction (both ends in the axial direction) open. The thickness of the clamping portion 121 is not greater than the width of the opening 1121 of the receiving groove 112, so as to facilitate the installation of the clamping plate 12 and the body 11.

[0030] The base 1 further includes rivets 13 and gears 14. Each connecting portion 122 requires two rivets 13 and one gear 14. The gear 14 includes a through hole 141 and a toothed portion 142 extending away from the through hole 141. When the splint 12 and the body 11 are installed, the connecting portion 122 of the splint 12 is inserted from one axial end of the accommodating groove 112 until it is completely placed in the accommodating groove 112; then, the gear 14 is placed outside one end of the accommodating groove 112 so that the through hole 141 of the gear 14 is aligned with the hollow part of the connecting portion 122; finally, one of the rivets 13 is inserted into one end of the connecting portion 122 of the splint 12 through the through hole 141 of the gear 14, and the other rivet 13 is inserted into the other end of the connecting portion 122 of the splint 12. The tail of the rivet 13 in the connecting portion 122 expands and is tightly locked with the inner circumferential wall of the connecting portion 122. At the same time, the size of the head of the rivet 13 exposed to the outside is larger than the size of the accommodating groove 112. The head of one rivet 13 presses the gear 14 against the end of the accommodating groove 112, and the head of the other rivet 13 abuts against the other end of the accommodating groove 112, further preventing the axial movement of the connecting portion 122. Thus, the rivet 13 limits the axial position of the splint 12 and the gear 14 relative to the body 11, preventing the splint 12 and the gear 14 from moving axially along the receiving groove 112, while ensuring that the splint 12 and the gear 14 are free in the circumferential direction relative to the body 11 and can rotate in the circumferential direction relative to the receiving groove 112.

[0031] The two gears 14 on the two splints 12 are meshed with each other. Since the gears 14 are clamped on the corresponding rivets 13, when one of the connecting parts 122 rotates, the rivet 13 thereon can drive the corresponding gear 14 to rotate, thereby driving the other connecting part 122 to rotate through the meshed gears 14, thereby allowing the two splints 12 to rotate synchronously.

[0032] The clamping part 121 of the clamping plate 12 is connected and fixed to the rib 100 by means of screws 123. The clamping part 121 is provided with screw holes 1214, and the screws 123 pass through the screw holes 1214 and the rib 100 to achieve connection and fixation. Due to such a connection method, the screws 123 are exposed, and the screw holes 1214 are also in an exposed state, so that rainwater may wash away the screws 123 and cause them to rust, or even leak from the side of the screw holes 1214 into between the clamping part 121 and the rib 100, and below the rib 100, thereby causing water leakage on the roof.

[0033] A common solution is to provide a waterproof assembly 15, which includes a lower sealing gasket 151 provided between the clamping portion 121 and the rib 100 to prevent side leakage. In addition, it also includes applying glass glue around the screw hole 1214 on the side of the clamping portion 121 away from the rib 100. However, the glass glue is easy to age and cannot ensure the sealing effect after one or two years.

[0034] To this end, in this embodiment, the waterproof component 15 further includes a waterproof cover 152 and an upper sealing gasket 153, both of which are arranged on the side of the clamping portion 121 away from the edge 100. For ease of arrangement, a first baffle 1211 extending upward is arranged at the bottom of the side of the clamping portion 121 away from the edge 100, and a second baffle 1212 extending upward is arranged in the middle, and the waterproof cover 152 and the upper sealing gasket 153 are arranged between the first baffle 1211 and the second baffle 1212.

[0035] The top of the first baffle 1211 is bent toward the second baffle 1212, and the top of the second baffle 1212 is also bent toward the first baffle 1212. The clamping portion 121 is provided with a downwardly recessed positioning groove 1213 between the first baffle 1211 and the second baffle 1212, and the shape and size of the upper sealing gasket 153 are adapted to the shape and size of the positioning groove 1213. Therefore, the upper sealing gasket 153 can be positioned between the first baffle 1211 and the second baffle 1212 through the positioning groove 1213 to prevent it from moving. The screw 123 also passes through the upper sealing gasket 153.

[0036] The waterproof cover 152 is used to cover the screw 123 and the screw hole 1214 to prevent water from entering and causing the screw 123 to rust, and further prevent water from entering from the screw hole 1214. The waterproof cover 152 is made of plastic, preferably, nylon 66, so that it has good anti-aging performance. The waterproof cover 152 extends from one side of the first baffle 1211 to form a first plug-in portion 1521, which can be inserted under the bent portion at the top of the first baffle 1211, and at the same time abuts against the upper sealing gasket 153 and has an interference fit with the first baffle 1211; the waterproof cover 152 is bent from one side of the second baffle 1212 to form a second plug-in portion 1522, which can be inserted under the bent portion at the top of the second baffle 1212, and abuts against the second baffle 1212 and the upper sealing gasket 153. In this embodiment, the first plug-in portion 1521 is in the shape of a flat plate, and the second plug-in portion 1522 is in the shape of a hook. Therefore, both sides of the waterproof cover 152 are in contact with the clamping portion 121 , and the force is balanced, so that the waterproof cover 152 will not be separated from the clamping portion 121 due to the force on one side.

[0037] Alternatively, glass glue may be used to replace the upper sealing gasket 153 .

[0038] See also Figure 2 , Figure 4 and Figure 5 The support 2 may adopt the existing technology or may be as in the present embodiment, including a first clamp 21 and a second clamp 22 located below the first clamp 21 , and the first clamp 21 can move up and down relative to the second clamp 22 .

[0039] The first clamp 21 includes a first clamp body 211 located in the middle and elastic pressing pieces 212 located on both sides of the first clamp body 211, and the outer end of the elastic pressing piece 212 has a first hook 2121 bent downward. The second clamp 22 includes a second clamp body 221 located in the middle and second hooks 222 bent upward corresponding to the first hook 211 located on both sides of the second clamp body 221, and the first hook 2121 and the second hook 222 cooperate to clamp the frames of two solar photovoltaic panels at the same time. The first clamp 21 and the second clamp 22 are both made of aluminum stretching, which can greatly reduce the manufacturing cost.

[0040] The support 2 further includes an adjustment seat 24 connected to the base 1, and a support assembly 23 connecting the first clamp 21, the second clamp 22 and the adjustment seat 24. The support assembly 23 enables the first clamp 21 and the second clamp 22 of the support 2 to move up and down relative to the base 1 as a whole. A first through hole 213 is provided on the first clamp body 211 of the first clamp 21, and a second through hole 223 is provided on the second clamp body 221 of the second clamp 22. The positions of the first through hole 213 and the second through hole 223 correspond to each other, and both extend in the longitudinal direction and penetrate the corresponding clamp body, and the second through holes 223 have internal threads.

[0041] The support assembly 23 includes a screw 231 and a first adjusting bolt 232, wherein the screw 231 is a double-threaded screw, including a screw head 2311 and a screw body 2312, wherein the screw head 2311 is formed at the top of the screw body 2312. The outer peripheral wall of the screw body 2312 has an external thread, and a threaded hole 2313 with an internal thread extending longitudinally and penetrating the screw 231 is provided between the screw head 2311 and the screw body 2312. The adjusting bolt 231 includes a bolt head 2321 and a bolt body 2322, wherein the bolt head 2321 is formed at a position close to the bottom of the bolt body 2322, and the portion of the bolt body 2322 located above the bolt head 2321 is formed with an external thread.

[0042] The support assembly 23 further includes a sealing ring 233 , a gasket 234 and a spring washer 235 . The outer diameters of the screw head 2311 and the spring washer 235 are larger than the diameter of the first through hole 213 , and the outer diameters of the bolt head 2321 and the gasket 234 are larger than the diameter of the second through hole 223 .

[0043] The support 2 further includes an adjustment seat 24 , on which a second adjustment bolt 241 is provided which can be inserted into the slide groove 111 of the body 11 of the base 1 , so that the adjustment seat 24 can move along the slide groove 111 to adjust the support 2 in the horizontal direction.

[0044] When the clamp 2 is installed, the spring washer 235 is placed on the top of the first through hole 213, and the screw 231 passes through the first through hole 213 of the first clamp body 211 and the second through hole 223 of the second clamp body 22 from top to bottom until the bottom of the screw head 2311 of the screw 231 abuts against the spring washer 235. At this time, the external thread of the screw 231 cooperates with the internal thread of the first through hole 213 and the second through hole 223 to lock the screw 231 with the first clamp 21 and the second clamp 22. Since the screw head 231 and the spring washer 235 abut against the first clamp body 211, after the screw 231 is locked with the second clamp 22, it is further locked with the first clamp 21 at the same time. When the adjustment is completed, the portion below the bolt head 2321 of the first adjusting bolt 232 is inserted downward into the adjusting seat 24, and the above-mentioned O-shaped sealing ring 233 is arranged between the bolt head 2321 of the first adjusting bolt 232 and the top of the adjusting seat 24, and the adjusting seat 24 is fixed with a gasket 234 on the bottom surface, and the portion above the bolt head 2321 of the first adjusting bolt 232 is inserted upward into the threaded hole 2313 of the screw 231, and is tightened so that the distance between the first clamp 21, the second clamp 22 and the adjusting seat 24 reaches the required degree, and then the second adjusting bolt 241 of the adjusting seat 24 is inserted into the slide groove 111 of the base 1, thereby completing the installation of the support 2 and the base 1.

[0045] In order to prevent the first adjusting bolt 232 from causing the screw 231 to rotate relative to the first clamp 21 and the second clamp 22 when adjusting the relative heights of the first clamp 21, the second clamp 22 and the base 1, in the present embodiment, the screw 231 and the second clamp 22 are matched with M16 threads, and the first adjusting bolt 232 and the screw 231 are matched with M10 threads. The preload force of the M16 thread is approximately three times the preload force of the M10 thread, thereby ensuring that rotating the first adjusting bolt 232 will not cause the screw 231 to rotate synchronously.

[0046] The structure of connecting the first clamp 21, the second clamp 22 and the base 1 with the support assembly 23 makes the threaded matching length of the support assembly 23 and the second clamp 22 longer, so that the connection is more stable.

[0047] See also Figure 1When the connector is installed, if the edge 100 of the trapezoidal tile is large in size, the connecting parts 122 of the two clamping plates 12 can be installed with the two outermost receiving grooves 112 of the base 1 respectively, and then the two clamping plates 12 are placed on both sides of the edge 100 of the trapezoidal tile, and one of the clamping plates 12 is rotated. Due to the action of the gear 14, the other clamping plate 12 is driven to rotate synchronously until the clamping parts 121 of the two clamping plates 12 are parallel to the corresponding sides of the edge 100 respectively (if the two clamping plates 12 do not rotate synchronously through the gear 14, it will cause one of them to rotate synchronously. The clamping portion 121 of one clamping plate 12 is parallel to the corresponding side of the edge 100, while the clamping portion 121 of the other clamping plate 12 may not remain parallel to the corresponding side of the edge 100, so that the installation cannot be completed). At the same time, a lower sealing gasket 151 is inserted between the clamping portion 121 and the edge 100, and an upper sealing gasket 153 is inserted on the other side of the clamping portion 121. The screw 123 is passed through the upper sealing gasket 153, the clamping portion 121, the lower sealing gasket 151 and the edge 100 and then fixed. Then the waterproof cover 152 of the waterproof component 15 is installed to complete the installation.

[0048] See also Figure 6 When the connecting piece is installed, if the edge 100 of the trapezoidal tile is small, the connecting parts 122 of the two clamping plates 12 can be installed with the two receiving grooves 112 in the middle of the base 1 respectively. The subsequent steps are the same as above. The size of the gear 14 can be adjusted appropriately, but both gears 14 must be ensured to be meshed.
