Among them, distributed photovoltaic power generation systems are the main construction form of future photovoltaic systems. Distributed photovoltaic power generation systems are mostly installed on roofs. The common application scenario is steel structure colored steel tiles. During the installation process, clamps are required to fix the photovoltaic panel components on the roof.

[0004] Regarding the above-mentioned related technologies, the installation of the clamp requires opening a through hole on the color steel tile, which is easy to damage the waterproof and anti-corrosion effects of the roof, and also affects the overall strength of the color steel tile, so it needs to be improved. Summary of the invention

[0005] In order to install photovoltaic panels on color steel tiles while reducing damage to the color steel tiles, the present application provides a ballast bracket.

[0006] The ballast bracket provided in this application adopts the following technical solution: A ballast bracket comprises a first support bar, a second support bar, a pallet, a counterweight block and a clamping assembly, wherein the first support bar and the second support bar are arranged in parallel, the pallet is used to connect the first support bar and the second support bar, and the counterweight block is arranged in the pallet; wherein a plurality of counterweight blocks are provided, and each of the counterweight blocks is distributed at intervals in the pallet; the first support bar and the second support bar are both provided with the clamping assembly, and the clamping assembly is used to clamp the photovoltaic panel.

[0007] By adopting the above technical solution, during installation, the first support bar and the second support bar are placed on the color steel tile, and the mutually parallel first support bar and the second support bar can well adapt to the surface of the color steel tile; then the counterweight block is placed in the tray, and the counterweight block can be a cement pier or gravel to increase the overall weight, thereby increasing the static friction between the bracket and the color steel tile. The presence of multiple counterweight blocks can further increase the static friction between the entire bracket and the color steel tile. Then the photovoltaic panel is laid on the first support bar and the second support bar, and the photovoltaic panel is clamped by the clamping assembly to fix the photovoltaic panel.

[0008] The entire installation structure does not require drilling holes on the color steel tile roof to complete the bracket fixation, reducing damage to the color steel tile. At the same time, the bracket also has sufficient stability after installation, and the bracket is not easy to fall off the color steel tile when facing strong winds.

[0009] In addition, it should be noted that the bracket of the present application can be used not only in the color steel tile scenario, but also in other scenarios, such as ground installation, roof installation or mountain installation.

[0010] Preferably, it also includes side wind shields and a rear wind shield, the side wind shields are provided on the first support bar and the second support bar, the rear wind shield is located between the two side wind shields and is used to connect the two side wind shields, and the side wind shields and the rear wind shield are both used to intercept wind.

[0011] By adopting the above technical solution, the side wind shield and the rear wind shield can both play a role in intercepting wind, preventing wind from penetrating into the bottom of the ballast bracket, and reducing the possibility of the photovoltaic panel being blown up.

[0012] Preferably, a hinge bar is rotatably connected to the first support bar, the hinge bar is buried in a groove of the first support bar, and the clamping assembly is provided at one end of the hinge bar away from the connection with the first support bar; when the hinge bar is rotated to form an angle with the first support bar, the hinge bar is used to support the photovoltaic panel.

[0013] By adopting the above technical solution, the hinged bar can be hidden in the groove of the first support bar when it is not needed, so as to reduce the packaging area and reduce the transportation cost. When the ballast bracket is in use, the hinged bar can be rotated so that an angle is formed between the hinged bar and the first support bar, so that the hinged bar can be fixed at a set angle and will not be closed back. Then the photovoltaic panel can be laid on the hinged bar so that the photovoltaic panel has a certain inclination angle. After adjustment, the photovoltaic panel can be compressed using the clamping assembly on the hinged bar. By rotating and snapping, the hinged bar can be opened and closed, making packaging more convenient and installation faster.

[0014] Preferably, a limiting clamping plate is connected in the groove of the first support bar, the limiting clamping plate is located on the rotation path of the hinge bar, and the limiting clamping plate is used to limit the rotation of the hinge bar.

[0015] By adopting the above technical solution, when the hinge bar rotates to a set angle, the limit clamp is clamped on the hinge bar to limit the rotation of the hinge bar, thereby preventing the hinge bar from being automatically closed into the groove of the first support bar due to pressure.

[0016] Preferably, the hinge strip is also provided with a front thread buckle and a rear thread buckle, respectively, the front thread buckle and the rear thread buckle are respectively located on both sides of the hinge strip, and the front thread buckle and the rear thread buckle are both used for limiting the connection of the photovoltaic panel.

[0017] By adopting the above technical solution, the front wire buckle and the rear wire buckle can be used to limit and restrain the wiring of the photovoltaic panel, avoiding the problem of messy wiring of the photovoltaic panel.

[0018] Preferably, a plurality of conductive spikes are provided on one end of the hinge bar away from its own rotation point, each of the conductive spikes is located in the same plane, and the conductive spikes are used to protect the photovoltaic panel.

[0019] By adopting the above technical solution, since photovoltaic panels can conduct electricity, they are easily damaged under some severe lightning conditions. Through the molding tool, conductive spikes are added to one end of the hinge bar used to support the photovoltaic panel. During the installation process, when the photovoltaic panel and the hinge bar are in contact, the conductive spikes can effectively pierce the anodized film of the aluminum frame, realize the current conduction between the photovoltaic panel frame and the hinge bar, and achieve the effect of lightning protection and grounding.

[0020] Preferably, the limiting clamping plate includes a first plate and a second plate that are integrally connected, the first plate is connected to the first support bar, a plane angle is formed between the second plate and the first plate, a clearance hole is provided at the bottom of the first support bar, and the plane angle is facing the clearance hole; a fixed plate is integrally connected to the rotating end of the hinge bar, and when the hinge bar rotates, the fixed plate is released and squeezed onto the second plate, the fixed plate is clamped in the clearance hole, and abuts against the end of the second plate away from the first plate.

[0021] By adopting the above technical solution, when the hinge bar rotates from the inside of the first support bar, the fixed plate will contact and squeeze the second plate, causing the second plate to produce metal deformation. When the fixed plate rotates to the end of the second plate away from the first plate, the fixed plate will fall into the clearance hole. At this time, the second plate can automatically reset under the elastic recovery force, so that the fixed plate is abutted by the end of the second plate, thereby limiting the hinge bar. When it is necessary to control the hinge bar to rotate back to the inside of the first support bar, the staff can apply external force downward to the second plate and cause it to deform, so as to prevent the second plate from blocking the rotation of the hinge bar, and finally rotate the hinge bar back to the first support bar.

[0022] Preferably, the clamping assembly comprises a connecting block, a pressing block, a fastening bolt, a fixing block and a spring; a mounting hole is provided on the first support bar; the connecting block is integrally connected with a wedge-shaped clamping block, and the wedge-shaped clamping block is clamped in the mounting hole; the pressing block is arranged on the connecting block and is used to be pressed on the photovoltaic panel, and a friction pattern is provided on the pressing surface of the pressing block; The connecting block has a cavity, a boss is connected to the connecting block, the boss is located in the cavity, and the fixing block is arranged on the boss; one end of the fastening bolt passes through the pressing block and the connecting block in turn, and is screwed to the fixing block, and the fastening bolt is used to lock the pressing block to the connecting block; the spring is arranged on the fastening bolt, and the spring is used to prevent the fastening bolt from loosening.

[0023] By adopting the above technical solution, the wedge-shaped clamping block is clamped in the mounting hole, thereby realizing the detachable connection between the connecting block and the first support bar. After the photovoltaic panel is laid on the first support bar and the second support bar, the pressing block is first pressed on the edge of the photovoltaic panel. Since the pressing surface of the pressing block is provided with friction lines, the friction lines can increase the roughness between the pressing block and the photovoltaic panel. After pressing, the pressing block is fixed by passing the fastening bolt through the pressing block and the connecting block and screwing it on the fixing block. Among them, the fastening bolt will compress the spring during the tightening process. The spring provides a pre-tightening force in the compressed state, which can help maintain the position of the fastening bolt and prevent it from loosening by itself. When external vibration or impact acts on the clamping assembly, the spring has a certain shock absorbing performance, which can absorb and buffer vibration and impact force, and reduce the possibility of loosening of the fastening bolt.

[0024] Preferably, the bottoms of the first support bar and the second support bar are both connected with anti-skid pads, and the anti-skid pads are made of anti-skid material.

[0025] By adopting the above technical solution, the anti-slip pad has a larger friction coefficient, which can increase the static friction of the contact between the entire ballast bracket and the color steel tile, and improve the overall stability of the bracket.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting a tray and a counterweight, the tray connects the first support bar and the second support bar together, and the counterweight is placed in the tray to increase the weight of the entire ballast bracket, increase the static friction between the bracket and the color steel tile, and then use the clamping assembly to install and fix the photovoltaic panel. The entire installation structure does not need to be fixed by drilling holes on the color steel tile roof, thereby reducing damage to the color steel tile.

[0036] The present application embodiment discloses a ballast bracket. Figure 1 The ballast bracket includes a first support bar 1, a second support bar 2, a tray 3, a counterweight 4 and a clamping assembly 5. The first support bar 1 and the second support bar 2 are arranged in parallel and are both used to be placed on the color steel tile. The tray 3 is used to connect the first support bar 1 and the second support bar 2 together. The counterweight 4 is placed in the tray 3. The counterweight 4 can be but not limited to cement piers, gravel, etc. There are several counterweights 4, and each counterweight 4 is distributed in the tray 3 at intervals; as shown in the figure, the number of counterweights 4 in this embodiment is five, and of course it can be other numbers in other embodiments.

[0037] Reference Figure 1 The first support bar 1 and the second support bar 2 are both provided with a pressing assembly 5, and the pressing assembly 5 is used to press the photovoltaic panel. Figure 2The clamping assembly 5 includes a connecting block 51, a pressing block 52, a fastening bolt 53, a fixing block 54 and a spring 55. The first support bar 1 and the second support bar 2 are both provided with mounting holes 6. The connecting block 51 is integrally connected with a wedge-shaped card block 7. There are two wedge-shaped card blocks 7. There is a gap between the two wedge-shaped card blocks 7, and they are used to be clamped in the mounting hole 6, so as to realize the detachable connection between the connecting block 51 and the first support bar 1. The pressing block 52 is located above the connecting block 51 and is used to be pressed on the edge of the photovoltaic panel. A plurality of friction lines 8 are provided on the pressing surface of the pressing block 52. The friction lines 8 can increase the roughness between the pressing block 52 and the photovoltaic panel, and improve the static friction between the pressing block 52 and the photovoltaic panel.

[0038] The connecting block 51 itself has a cavity, and a boss 9 is connected to the connecting block 51. The boss 9 is located in the cavity of the connecting block 51, and the fixing block 54 is placed on the boss 9. After the pressing block 52 is pressed on the photovoltaic panel, one end of the fastening bolt 53 passes through the pressing block 52 and the connecting block 51 in turn, and is screwed on the fixing block 54. The fastening bolt 53 is used to lock the pressing block 52 on the connecting block 51. The spring 55 is sleeved on the fastening bolt 53, and the elastic force direction of the spring 55 is the length direction of the fastening bolt 53. The fastening bolt 53 will compress the spring 55 during the tightening process. The spring 55 provides a pre-tightening force in the compressed state, which can help maintain the position of the fastening bolt 53 and prevent it from loosening by itself. When external vibration or impact acts on the clamping assembly 5, the spring 55 has a certain shock absorbing performance, which can absorb and buffer vibration and impact force, and reduce the possibility of loosening of the fastening bolt 53.

[0039] Combination Figure 3 During installation, place the first support bar 1 and the second support bar 2 on the color steel tile; then place several counterweights 4 in the tray 3 to increase the overall weight, thereby increasing the static friction between the bracket and the color steel tile. Then lay the photovoltaic panel on the first support bar 1 and the second support bar 2, and clamp the photovoltaic panel through the clamping assembly 5 to fix the photovoltaic panel. The entire installation structure does not require drilling holes on the color steel tile roof to complete the fixation of the bracket, thereby reducing damage to the color steel tile. At the same time, the bracket also has sufficient stability after installation, and the bracket is not easy to fall off the color steel tile when facing strong winds. In addition, it should be noted that in addition to being used in the scene of color steel tiles, the bracket can also be used in other scenes, such as ground installation or mountaintop installation.

[0040] Reference Figure 4 and Figure 5, wherein the first support bar 1 is rotatably connected with a hinge bar 10, the rotation axis of the hinge bar 10 is perpendicular to the length direction of the first support bar 1, and the hinge bar 10 is buried in the groove of the first support bar 1. Among them, a clamping assembly 5 is installed at the end of the hinge bar 10 away from the first support bar 1. In order to facilitate the installation of the clamping assembly 5, a corresponding installation hole 6 is also provided on the hinge bar 10 for the installation of the clamping assembly 5. When the hinge bar 10 is rotated to form an angle with the first support bar 1, the hinge bar 10 is used to support the photovoltaic panel so that the photovoltaic panel has a certain inclination angle, and the clamping assembly 5 on the hinge bar 10 is used to clamp the photovoltaic panel. As shown in the figure, the hinge bar 10 is also rotatably connected to the second support bar 2, and the two hinge bars 10 are used together for the installation of the photovoltaic panel. In this way, the number of the clamping assemblies 5 in this embodiment is four groups in total, namely, one group on the first support bar 1, one group on the second support bar 2, and one group on each of the two hinge bars 10.

[0041] Combination Figure 6 Specifically, a limiting card plate 11 is connected to the groove at the bottom of the first support bar 1. The limiting card plate 11 is located on the rotation path of the hinge bar 10, and the limiting card plate 11 is used to limit the rotation of the hinge bar 10. The limiting card plate 11 includes a first plate 111 and a second plate 112 that are integrally connected. The first plate 111 is fixedly connected to the bottom of the first support bar 1, and a plane angle is formed between the second plate 112 and the first plate 111, and the plane angle is an obtuse angle. A clearance hole 12 is opened at the bottom of the first support bar 1. The clearance hole 12 is close to the position of the limiting card plate 11, and the plane angle between the second plate 112 and the first plate 111 is toward the clearance hole 12.

[0042] A fixed plate 13 is integrally connected to the end of the hinged bar 10 where it rotates. When the hinged plate starts to rotate from the first support bar 1, the fixed plate 13 contacts and presses on the second plate 112, causing the second plate 112 to produce metal deformation. When the fixed plate 13 rotates to the end of the second plate 112 away from the first plate 111, the fixed plate 13 will fall into the clearance hole 12. At this time, the second plate 112 can automatically reset under the elastic recovery force, so that the fixed plate 13 is abutted by the end of the second plate 112, thereby limiting the hinged bar 10. When it is necessary to control the hinged bar 10 to rotate back to the inside of the first support bar 1, the staff can apply external force downward to the second plate 112 to cause it to deform, so as to prevent the second plate 112 from blocking the rotation of the hinged bar 10, and finally rotate the hinged bar 10 back to the first support bar 1.

[0043] The hinged bar 10 can be hidden in the groove of the first support bar 1 when not in use, so as to reduce the packaging area and transportation cost. When the ballast bracket is in use, the hinged bar 10 can be rotated so that an angle is formed between the hinged bar 10 and the first support bar 1, so that the hinged bar 10 can be fixed at a set angle and will not be closed. Then the photovoltaic panel can be laid on the hinged bar 10, so that the photovoltaic panel has a certain inclination angle. By rotating and snapping, the hinged bar 10 can be opened and closed, making packaging more convenient and installation faster.

[0044] In some embodiments, please refer to Figure 4 A plurality of conductive spikes 16 are fixed on one end of the hinged bar 10 away from its own rotation point. Each conductive spike 16 is located in the same plane, and the conductive spikes 16 are used to protect the photovoltaic panel. After the photovoltaic panel is installed on the ballast bracket, it may be threatened by lightning strikes when encountering some harsh environments, causing damage to the photovoltaic panel. By adding conductive spikes 16 to one end of the hinged bar 10 used to support the photovoltaic panel, during the installation process, when the photovoltaic panel and the hinged bar 10 are in contact, the conductive spikes 16 can effectively pierce the anodized film of the aluminum frame, realize the current conduction between the photovoltaic panel frame and the hinged bar 10, achieve the lightning protection grounding effect, and can effectively conduct the lightning current into the ground, which plays a protective role on the photovoltaic panel.

[0045] Please refer to Figure 5 In addition, a front line buckle 14 and a rear line buckle 15 are respectively installed on the outer surface of the hinged strip 10. The front line buckle 14 and the rear line buckle 15 are respectively located on both sides of the hinged strip 10. The front line buckle 14 and the rear line buckle 15 are used to limit and restrain the wiring of the photovoltaic panel to avoid the problem of messy wiring of the photovoltaic panel and improve the overall aesthetics.

[0046] According to some embodiments of the present application, optionally, please refer to Figure 1 The bottom of the first support bar 1 and the second support bar 2 are fixedly connected with an anti-skid pad 17, which is made of an anti-skid material, such as rubber, silicone, polyester or PVC. The anti-skid pad 17 has a large friction coefficient, which can increase the static friction between the entire ballast bracket and the color steel tile, and improve the overall stability of the ballast bracket.

[0047] In addition, side wind shields 18 are installed on the first support bar 1 and the second support bar 2. The wind shields 18 on both sides are connected together by a rear wind shield 19. The side wind shields 18 and the rear wind shields 19 are used to intercept wind to prevent wind from penetrating into the bottom of the ballast bracket, thereby reducing the possibility of the photovoltaic panels being blown up and improving the stability of the ballast bracket.

[0048] The implementation principle of a ballast bracket in the embodiment of the present application is as follows: during installation, the first support bar 1 and the second support bar 2 are placed on the color steel tile; then the counterweight block 4 is placed in the tray 3 to increase the overall weight of the bracket. Then, force is applied to the hinge bar 10 on the first support bar 1 and the second support bar 2, and the hinge bar 10 is controlled to rotate until the hinge bar 10 is clamped and no longer rotates; then the photovoltaic panel is laid on the first support bar 1 and the second support bar 2, and the photovoltaic panel is clamped by the clamping assembly 5 to fix the photovoltaic panel. The entire installation structure does not need to be fixed by drilling holes on the color steel tile roof, thereby reducing damage to the color steel tile.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
