Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation panel mounting brackets, in particular to a photovoltaic mounting bracket for rooftop photovoltaic power generation panels. Background Art

[0002] Photovoltaic mounting brackets for rooftop photovoltaic panels are support structures specially designed for installing photovoltaic panels on roofs.

Furthermore, 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 is only necessary 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.

[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, the screw mounting frame is fixedly connected to the photovoltaic mounting bracket, the top of the inner wall of the screw mounting frame is fixedly connected to a waterproof glue bag, the screw mounting frame is slidably connected to a trigger rod, and the trigger rod is evenly fixedly connected to a plurality of liquid bag needles on the side close to the fixing screw, and the two photovoltaic mounting brackets are both slidably connected to a trigger column, and the L-shaped rotating rod and the square rotating rod are fixedly connected to one end close to the adjacent photovoltaic mounting bracket with a convex column.

[0013] Furthermore, a guide groove is provided on the top of the screw installation frame, and the waterproof plastic 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 the waterproof glue liquid bag stores waterproof glue inside.

In addition, due to the adhesive properties 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.

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 wind and sun in the external environment, and can enhance the stability of the connection point between the fixing screw and the roof.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall 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 rooftop 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 Figures 1-6 As shown, the two photovoltaic mounting brackets 1 are provided with a cross-bracing fixing assembly, which is used to enhance the fixing effect between the two photovoltaic mounting brackets 1 and the roof. The cross-bracing 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 rotated and 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. 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 an isosceles trapezoid. The bottom of the L-shaped rotating rod 31 is provided 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. Without going into details, the inner surface of the sealing guard plate 33 is symmetrically fixedly connected with two liquid sac plates 36, the convex liquid sac 35 is located on the falling path of the liquid sac plates 36, and the bottom of the end of the two liquid sac plates 36 close to each other is set to a serrated shape, 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 set in the middle of the square rotating rod 37. The top and bottom surfaces 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 When the two cams 31 are in contact with each other, the two cams 31 are in a state of being rotated on the support plate 38. When the two cams 31 are in contact with each other, the support plate 38 is in a state of being rotated on the support plate 38. When the two cams 31 are in contact with each other, the support plate 38 is in a state of being rotated on the support plate 38.

[0040] like Figure 7-10As shown, each fixing screw 2 is provided with a glue-filling sealing assembly, which is used to prevent the fixing screw 2 from drilling holes and causing damage to the roof waterproof surface, and to enhance the connection strength between the fixing screw 2 and the roof. The glue-filling sealing assembly includes a screw mounting frame 41, which 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 capsule 42 is fixedly connected to the top of the inner wall of the screw mounting frame 41. Waterproof glue is stored in the waterproof glue capsule 42. The waterproof glue is an existing known technology and will not be described in detail here. The waterproof glue 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. The waterproof plastic capsule 42 is located on the moving path of the liquid capsule needle 44. Only one trigger rod 43 is installed on each photovoltaic mounting bracket 1. 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. Trigger columns 45 are slidably connected to the two photovoltaic mounting brackets 1. The trigger rod 43 is fixedly connected to the adjacent trigger columns 45. 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 limiting 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 steps for running the job 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 photovoltaic mounting bracket 1 and the bottom surface of 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 rod 37 in the direction of the L-shaped rod 31. As the square rod 37 is rotated, the square 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 rod 37 is rotated to a horizontal position, the installer then rotates the L-shaped rod 31 close to the rotated square rod 37. At this time, the arrow plate 311 is facing the direction of the L-shaped rod 31. As the L-shaped rod 37 is rotated, the installer rotates the L-shaped rod 31 close to the rotated square rod 37. As the arrow plate 311 gradually approaches the square rotating rod 37, it will enter the tightening groove 32. At this time, the two side wing plates 39 are squeezed by the tightening groove 32, causing the two side wing plates 39 to 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, causing the two side wing plates 39 to 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. Then, under the action of gravity, the sealing guard plate 33 slides to the bottom on the L-shaped rotating rod 31. 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 glue 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 conflicts with the L-shaped rotating rod 31, and the side wing plate 39 conflicts 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 glue fixes the L-shaped rotating rod 31, the square rotating rod 37 and 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 strong winds or heavy rain due to the suspended connecting rod, and ensuring the stability of the photovoltaic panel during use.

[0050] Since the L-shaped rotating rod 31 and the square rotating rod 37 are connected in a rotating card connection mode, 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 panels 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 clamped 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 connect the two horizontal supports at the bottom of the photovoltaic mounting brackets 1, avoiding tedious installation and wasting time, thereby improving the work efficiency of the installer.

[0052] The following reference Figures 6-10 As shown, during the rotation of the L-shaped rotating rod 31 and the square rotating rod 37, the protruding column 46 contacts 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. Then, as the liquid capsule needle 44 moves, 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 toward the connection position between the roof and the fixing screw 2 under the action of gravity. Due to its fluid properties, the waterproof glue is able to 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 properties 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 since 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 wind and sun in 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.
