Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel mounting brackets, and in particular to a photovoltaic mounting bracket for a roof photovoltaic panel. Background Art

[0002] The photovoltaic mounting bracket for rooftop photovoltaic panels is a supporting structure specially designed for installing photovoltaic panels on the roof.

[0003] Patent publication number CN217362986U discloses a solar panel mounting bracket for photovoltaic power generation, comprising: a base plate, two groups of base plates are arranged at intervals, and a telescopic component is arranged between the two groups of base plates, and the telescopic component is used to adjust the distance between the two groups of base plates to adapt to solar panels of different widths; the utility model facilitates the adjustment of the distance between the two groups of base plates by setting two groups of connecting rods, which can not only adapt to solar panels of different widths but also facilitate the storage of the base plates, saving transportation space, and further, the mounting plate is supported by the set support rod, and the user can select the socket for the plug rod to be connected according to the actual fixed angle. When adjusting, it only needs to press the plug rod to disengage it from the socket and connect it to the appropriate socket. At the same time, during transportation and storage, the mounting plate can be slid to the inner side of the accommodating groove, thereby further reducing the occupied space.

[0004] When using the above-mentioned photovoltaic solar panel mounting bracket, the connecting rod between the two sets of base plates can only provide the function of adjusting the spacing, and during normal use, the connecting rod is in a suspended state and has no connection with the roof, and cannot provide support for the two sets of base plates. In particular, when the base plates are used outdoors, in strong winds or heavy rain, the connecting rod may shake, thereby affecting the stability of the solar panel.

[0005] To this end, a photovoltaic mounting bracket for rooftop photovoltaic panels is proposed. Summary of the invention

[0009] Furthermore, the convex liquid capsule is located on the falling path of the liquid capsule piercing plate, and the bottom of one end of the liquid capsule piercing plate close to each other is configured to be serrated.

[0010] Furthermore, the bearing plate is arranged at the middle part of the square rotating rod.

[0011] Furthermore, the bottoms of the ends of the two limiting plates close to each other are both configured to be triangular, and the material of the limiting plates is configured to be an elastic metal sheet.

[0012] Furthermore, each of the fixing screws is provided with a glue-filling sealing assembly, and the sealing glue-filling assembly includes a screw mounting frame, and the screw mounting frame is fixedly connected to the photovoltaic mounting bracket, and a waterproof glue liquid bag is fixedly connected to the top of the inner wall of the screw mounting frame, and a trigger rod is slidably connected to the screw mounting frame, and a plurality of liquid bag needles are evenly fixedly connected to the side of the trigger rod close to the fixing screw, and a trigger column is slidably connected to the two photovoltaic mounting brackets, and a convex column is fixedly connected to one end of the L-shaped rotating rod and the square rotating rod close to the adjacent photovoltaic mounting bracket.

[0013] Furthermore, a guide groove is provided on the top of the screw installation frame, and the waterproof glue bag is concentrically arranged with the guide groove of the screw installation frame.

[0014] Furthermore, the bottom surface of the screw mounting frame and the bottom surface of the photovoltaic mounting bracket are on the same horizontal plane, and waterproof glue is stored in the waterproof glue liquid bag.

[0015] Furthermore, the waterproof gel capsule is located on the moving path of the capsule needle, and the trigger column is located on the rotation path of the convex column.

[0016] Furthermore, only one trigger rod is installed on each photovoltaic mounting bracket, and the trigger rod on each photovoltaic mounting bracket is slidably connected to a screw mounting frame on the same photovoltaic mounting bracket, and the trigger rod is fixedly connected to an adjacent trigger column.

[0020] The installer only needs to turn the L-shaped rotating rod and the square rotating rod to connect the two photovoltaic mounting brackets, thus avoiding the cumbersome installation and wasting time, and improving the work efficiency of the installer.

[0021] The surface of the waterproof glue sac is punctured by the sac needle, so that the waterproof glue inside the waterproof glue sac flows to the roof under the action of gravity. Due to its fluid characteristics, the waterproof glue can flow into the connection point between the fixing screw and the roof and the roof around the connection point between the fixing screw and the roof, so as to repair the waterproof layer of the roof damaged by drilling. In addition, due to the bonding characteristics of the waterproof glue after drying, the connection between the fixing screw and the roof can be made stronger, thereby making the installation of the photovoltaic mounting bracket more stable.

[0022] The connection point between the fixing screw and the roof is located inside the screw installation frame. The screw installation frame plays a shielding and protective role, which can prevent the connection point between the fixing screw and the roof from being affected by the wind and sun of the external environment, and can enhance the stability of the connection point between the fixing screw and the roof.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] An embodiment provided by the present invention: Figure 1 As shown, a photovoltaic mounting bracket for a roof photovoltaic power generation panel includes two photovoltaic mounting brackets 1. Each photovoltaic mounting bracket 1 is provided with at least four fixing screws 2 around it. The photovoltaic mounting bracket 1 and the fixing screws 2 are both existing known technologies and will not be described in detail here.

[0039] like Figure 1-Figure 6 As shown, the two photovoltaic mounting brackets 1 are jointly provided with a cross brace fixing assembly, which is used to enhance the fixing effect between the two photovoltaic mounting brackets 1 and the roof. The cross brace fixing assembly includes an L-shaped rotating rod 31 and a square rotating rod 37. The L-shaped rotating rod 31 and the square rotating rod 37 are respectively rotatably connected to the side close to the two photovoltaic mounting brackets 1, and the sizes of the L-shaped rotating rod 31 and the square rotating rod 37 are adapted, which can be referred to Figure 3 The L-shaped rotating rod 31 and the square rotating rod 37 can be plugged into a horizontal long rod after rotation. A tightening groove 32 is provided on the L-shaped rotating rod 31. The shape of the tightening groove 32 is set to be an isosceles trapezoid. The bottom of the L-shaped rotating rod 31 is sleeved with a sealing guard plate 33. A U-shaped hanging plate 34 is provided on the side of the L-shaped rotating rod 31 close to the photovoltaic mounting bracket 1 on the same side. A convex liquid capsule 35 is fixedly connected to the bottom of the L-shaped rotating rod 31. The convex liquid capsule 35 stores foam glue inside. The foam glue is a known technology in the prior art. Without further elaboration, the inner surface of the sealing guard plate 33 is symmetrically fixedly connected with two liquid capsule tie plates 36, the convex liquid capsule 35 is located on the falling path of the liquid capsule tie plates 36, and the bottom of the end of the two liquid capsule tie plates 36 close to each other is set to be serrated, and the side of the square rotating rod 37 close to the photovoltaic mounting bracket 1 on the same side is fixedly connected with a bearing plate 38, and the bearing plate 38 is arranged in the middle of the square rotating rod 37, and the top surface and the bottom surface of the bearing plate 38 are symmetrically rotated and connected with side wing plates 39, and the two side wing plates 39 are connected to the bearing plate 3 The two ends of the support plate 312 are fixedly connected to each other with a spring 310, and the end of the support plate 38 away from the square rotating rod 37 is fixedly connected to the arrow plate 311. In the initial state where the spring 310 has not undergone elastic deformation, the side of the two side wing plates 39 away from each other is in contact with the arrow plate 311, and the angle between the two side wing plates 39 is greater than the angle between the two waists of the isosceles trapezoidal shape of the tightening groove 32. The function is that when the two side wing plates 39 resist the tightening groove 32, the tightening groove 32 can squeeze the two side wing plates 39 so that the two side wing plates 39 rotate toward each other on the support plate 38, and the two photovoltaic mounting brackets 1 are fixedly connected to a limit plate 312 on each side close to each other. The bottom of the end of the two limit plates 312 close to each other is set to a triangle, and the material of the limit plate 312 is set to an elastic metal sheet, which is used to prevent the L-shaped rotating rod 31 and the square rotating rod 37 from shaking during the transportation and handling of the photovoltaic mounting bracket 1, causing them to rotate on the photovoltaic mounting bracket 1, affecting the transportation and handling of the photovoltaic mounting bracket 1.

[0040] like Figure 7-10As shown, each fixing screw 2 is provided with a glue-filling sealing component, and the sealing glue-filling component is used to prevent the fixing screw 2 from drilling holes and causing the roof waterproof surface to be damaged, and to enhance the connection strength between the fixing screw 2 and the roof. The sealing glue-filling component includes a screw mounting frame 41, and the screw mounting frame 41 is fixedly connected to the photovoltaic mounting bracket 1. A guide groove is provided on the top of the screw mounting frame 41. The bottom surface of the screw mounting frame 41 and the bottom surface of the photovoltaic mounting bracket 1 are in the same horizontal plane. A waterproof glue liquid capsule 42 is fixedly connected to the top of the inner wall of the screw mounting frame 41. The waterproof glue liquid capsule 42 stores waterproof glue inside. The waterproof glue is an existing known technology and is not described in detail here. The waterproof glue liquid capsule 42 is annular and is in the same horizontal plane as the guide groove of the screw mounting frame 41. The center is set, a trigger rod 43 is slidably connected to the screw mounting frame 41, and a plurality of liquid capsule needles 44 are evenly fixedly connected to the side of the trigger rod 43 close to the fixing screw 2, and the waterproof glue capsule 42 is located on the moving path of the liquid capsule needle 44, and only one trigger rod 43 is installed on each photovoltaic mounting bracket 1, and the trigger rod 43 on each photovoltaic mounting bracket 1 is slidably connected to the screw mounting frame 41 on the same photovoltaic mounting bracket 1, and a trigger column 45 is slidably connected to the two photovoltaic mounting brackets 1, and the trigger rod 43 is fixedly connected to the adjacent trigger column 45, and the L-shaped rotating rod 31 and the square rotating rod 37 are fixedly connected to one end of the adjacent photovoltaic mounting bracket 1 with a boss 46, and the trigger column 45 is located on the rotation path of the boss 46.

[0041] Specifically, during transportation, the installer can use tape to fix the trigger rod 43 and the trigger column 45 on the photovoltaic mounting bracket 1 to prevent the trigger rod 43 and the trigger column 45 from moving due to transportation shaking. When the two photovoltaic mounting brackets 1 are subsequently installed, the tape can be torn off so that the trigger rod 43 can slide on the screw mounting frame 41.

[0042] The above implementation works as follows:

[0043] The initialization steps are as follows:

[0044] One end of the triangle of the two limit plates 312 respectively contacts the L-shaped rotating rod 31 and the square rotating rod 37. The inner surface of the U-shaped hanging plate 34 is sleeved on the outside of the same side of the L-shaped rotating rod 31 and the sealing guard plate 33. The liquid sac piercing plate 36 is located on the top of the convex liquid sac 35, and the convex column 46 does not rotate to contact the trigger column 45.

[0045] The working steps are as follows:

[0046] The installer installs multiple fixing screws 2 on the roof through the guide grooves on the L-shaped rotating rod 31. At this time, the lower surface of the top of the fixing screw 2 coincides with the top surface of the screw mounting frame 41, the waterproof glue bag 42 surrounds the outside of the fixing screw 2, and the bottom surface of the photovoltaic mounting bracket 1 and the L-shaped rotating rod 31 are in contact with the roof.

[0047] The following reference Figure 1-Figure 5 As shown, at this time, the installer rotates the square rotating rod 37 in the direction of the L-shaped rotating rod 31. When the square rotating rod 37 is rotated, the square rotating rod 37 squeezes the limit plate 312 in the direction away from the photovoltaic mounting bracket 1, so that the end of the limit plate 312 away from the photovoltaic mounting bracket 1 is squeezed and deformed, causing it to tilt. When the square rotating rod 37 is rotated to a horizontal state, the installer then rotates the L-shaped rotating rod 31 close to the rotated square rotating rod 37. At this time, the arrow plate 311 is facing the direction of the L-shaped rotating rod 31. As the L-shaped rotating rod 37 is rotated, the arrow plate 311 is facing the direction of the L-shaped rotating rod 31. As the two side wing plates 39 are gradually approaching the square rotating rod 37, the arrow plate 311 will enter the tightening groove 32. At this time, the two side wing plates 39 are squeezed by the tightening groove 32, so that the two side wing plates 39 rotate toward each other on the bearing plate 38, so that the spring 310 is elastically compressed. When the two side wing plates 39 completely pass through the tightening groove 32, the spring 310 elastically stretches, so that the two side wing plates 39 rotate relative to each other. At this time, the end of the side wing plate 39 away from the arrow plate 311 is in contact with the side of the L-shaped rotating rod 31 close to the U-shaped hanging plate 34.

[0048] In the process of the arrow plate 311 passing through the tightening groove 32, the arrow plate 311 pushes the U-shaped hanging plate 34 in the direction away from the L-shaped rotating rod 31, so that the U-shaped hanging plate 34 no longer conflicts with the L-shaped rotating rod 31 and the sealing guard plate 33, and then under the action of gravity, the sealing guard plate 33 slides to the bottom on the L-shaped rotating rod 31, and as the sealing guard plate 33 moves downward, the liquid sac piercing plate 36 moves downward synchronously with the sealing guard plate 33. In the process of the liquid sac piercing plate 36 moving downward, the serrated end of the liquid sac piercing plate 36 scrapes the surface of the convex liquid sac 35, so that the foam glue in the cavity of the convex liquid sac 35 flows to the bottom of the L-shaped rotating rod 31 under the action of gravity, and gradually contacts the roof as the sealing guard plate 33 falls.

[0049] At this time, a closed cavity is formed between the bottom of the L-shaped rotating rod 31, the sealing guard plate 33 and the roof, and then the foam expands in the closed cavity and bonds the roof to the L-shaped rotating rod 31 and the sealing guard plate 33. At this time, the side wing plate 39 is in conflict with the L-shaped rotating rod 31, and the side wing plate 39 is in conflict with the arrow plate 311, which limits the reverse rotation of the side wing plate 39. At this time, the L-shaped rotating rod 31 and the square rotating rod 37 form a whole. At this time, the bonding of the foam makes the L-shaped rotating rod 31 and the square rotating rod 37 fixed to the roof, solving the problem that the existing connecting rod is suspended and cannot be fixed to the roof, avoiding the situation where the photovoltaic panel is prone to shaking due to the hanging connecting rod in strong winds or heavy rain, and ensuring the stability of the photovoltaic panel during use.

[0050] Due to the rotational connection of the L-shaped rotating rod 31 and the square rotating rod 37, and the bearing plate 38 is arranged in the middle of the square rotating rod 37, the tightening groove 32 is arranged longer. Figure 3As shown, no matter how much the distance between the two photovoltaic mounting brackets 1 is, the two side wing plates 39 can enter a certain position of the tightening groove 32, so that the L-shaped rotating rod 31 and the square rotating rod 37 can be smoothly snap-connected and fixed, which can adapt to the different installation distances between the two photovoltaic mounting brackets 1 and ensure the connection effect of the two photovoltaic mounting brackets 1.

[0051] Moreover, the installer only needs to rotate the L-shaped rotating rod 31 and the square rotating rod 37 to realize the cross-bracing connection at the bottom of the two photovoltaic mounting brackets 1, thereby avoiding cumbersome installation and wasting time, and improving the work efficiency of the installer.

[0052] The following reference Figure 6-Figure 10 As shown, during the rotation of the L-shaped rotating rod 31 and the square rotating rod 37, the protruding column 46 abuts against the triggering column 45, and causes the triggering column 45 to slide in the direction away from the square rotating rod 37 inside the photovoltaic mounting bracket 1. The sliding of the triggering column 45 drives the triggering rod 43 to move synchronously in the direction away from the square rotating rod 37, and at the same time as the movement of the triggering rod 43, drives the liquid capsule needle 44 to move in the direction of the waterproof glue liquid capsule 42 inside all the screw mounting frames 41, and then with the movement of the liquid capsule needle 44, the liquid capsule needle 44 will pierce the surface of the waterproof glue liquid capsule 42, allowing the waterproof glue inside the waterproof glue liquid capsule 42 to flow to the connection position between the roof and the fixing screw 2 under the action of gravity. Due to its fluid characteristics, the waterproof glue can flow into the connection point between the fixing screw 2 and the roof and the roof around the connection point between the fixing screw 2 and the roof, so as to repair the waterproof layer of the roof damaged by drilling, and due to the bonding characteristics of the waterproof glue after drying, the connection between the fixing screw 2 and the roof can be made stronger, thereby making the installation of the photovoltaic mounting bracket 1 more stable.

[0053] And because the connection point between the fixing screw 2 and the roof is located inside the screw installation frame 41 at this time, the screw installation frame 41 can play a shielding and protective role, which can prevent the connection point between the fixing screw 2 and the roof from being affected by the wind and sun of the external environment, and can enhance the stability of the connection point between the fixing screw 2 and the roof.

[0054] At this point, the overall operation of the photovoltaic mounting bracket for rooftop photovoltaic panels is completed.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
