Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a seismic-resistant aluminum alloy photovoltaic support. Background Technology

[0002] Solar photovoltaic (PV) mounting brackets are special supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel.

[0003] Most photovoltaic (PV) mounting systems on the market consist of three main parts: ground support frames, cross frames, and mounting frames. The ground support frames are fixed to the cross frames, and the mounting frames are fixed to the cross frames, mostly connected by sleeves and fasteners. This results in a rigid connection between the ground support frames, cross frames, and mounting frames. In actual use, when external vibrations are transmitted to the PV mounting system, the rigid structure cannot effectively absorb and resist the vibrations. This can lead to problems such as reduced power generation efficiency of the PV panels or the mounting system, component damage, structural loosening, or changes in the installation angle, thereby reducing the safety and stability of the PV panels after installation.

[0004] In view of this, it is particularly important to design and manufacture an aluminum alloy photovoltaic bracket that can effectively reduce vibration damage to photovoltaic panels after installation and improve the seismic resistance of photovoltaic panels after installation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of reduced power generation efficiency, component damage, structural loosening, or changes in installation angle that occur in the original aluminum alloy photovoltaic brackets due to the rigid fixing method, which reduces the safety and stability of the photovoltaic panels after installation. Therefore, a seismic-resistant aluminum alloy photovoltaic bracket is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An earthquake-resistant aluminum alloy photovoltaic bracket includes two vertically symmetrically distributed ground support frames, a cross frame disposed between the upper ends of the two ground support frames, and multiple mounting frames equidistantly disposed above the cross frame. Earthquake-resistant mounting seats for detachable mounting of the ground support frames and mounting frames onto the cross frame are provided between the upper end of the ground support frame and the cross frame, and between the lower end of the mounting frame and the cross frame.

[0008] As a further description of the above technical solution:

[0009] The seismic mounting base includes a fixed outer cylinder fixed to the upper end of the ground support frame and the lower end of the mounting frame, a fixed inner cylinder set at the axis of the fixed outer cylinder and matched with the cross frame, a rubber block filled between the cavity of the fixed outer cylinder and the fixed inner cylinder, and a plastic protective cover detachably installed on the outer sides of both ends of the fixed outer cylinder and wrapped around the rubber block.

[0010] As a further description of the above technical solution:

[0011] The outer periphery of the fixed outer cylinder is fixedly connected with multiple positioning grooves arranged in a ring array and recessed inwards. The side of the plastic cover facing the positioning groove is fixedly connected with a positioning block that matches the positioning groove.

[0012] As a further description of the above technical solution:

[0013] A triangular support frame is fixedly connected between the fixed outer cylinder and the mounting frame.

[0014] As a further description of the above technical solution:

[0015] Both the cross-section of the cross frame and the fixed inner cylinder are rectangular structures. The left and right ends of the fixed inner cylinder are fitted with fixing bolts whose inner ends can abut against the outer wall of the cross frame by threaded engagement.

[0016] As a further description of the above technical solution:

[0017] Anti-deviation protrusions are fixedly connected to the four corners of the outer side of the fixed inner cylinder.

[0018] As a further description of the above technical solution:

[0019] The rubber block is made of EPDM rubber.

[0020] As a further description of the above technical solution:

[0021] The lower end of the ground support frame is fixedly connected to a fixing base, and the fixing base has multiple mounting holes.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] In this invention, the original aluminum alloy photovoltaic support structure has been scientifically and rationally improved. A fixed outer cylinder, a fixed inner cylinder, fixing bolts, rubber blocks, and a plastic cover are installed at the upper end of the ground support frame and the lower end of the mounting frame. Both the ground support frame and the mounting frame can be slidably installed onto the crossbeam through the fixed inner cylinder. At this point, the connection nodes between the ground support frame and the crossbeam, as well as between the mounting frame and the crossbeam, have a three-layered anti-vibration mounting base structure. When external vibration is transmitted to the anti-vibration mounting base, the vibration can be transmitted to the rubber blocks through the rigid fixed outer and inner cylinders on both sides. The rubber blocks can absorb and resist the vibration, thereby inhibiting its further transmission. This structure allows the ground support frame and the mounting frame to be combined and anti-vibrationally installed on the crossbeam, effectively reducing problems such as decreased power generation efficiency, component damage, structural loosening, or changes in installation angle caused by vibration, thus improving the safety and stability of the photovoltaic panels after installation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-3This utility model provides a technical solution: a seismic-resistant aluminum alloy photovoltaic bracket, including two vertically symmetrically distributed ground support frames 1, a cross frame 2 set between the upper ends of the two ground support frames 1, and a plurality of mounting frames 3 equidistantly set above the cross frame 2. Seismic mounting seats for detachable mounting of the ground support frames 1 and the mounting frames 3 on the cross frame 2 are provided between the upper end of the ground support frame 1 and the cross frame 2, and between the lower end of the mounting frame 3 and the cross frame 2.

[0031] Specifically, such as Figure 1-3 As shown, the seismic mounting base includes a fixed outer cylinder 4 fixed to the upper end of the ground support frame 1 and the lower end of the mounting frame 3, a fixed inner cylinder 5 set at the axis of the fixed outer cylinder 4 and matched with the cross frame 2, a rubber block 6 filled between the cavity of the fixed outer cylinder 4 and the fixed inner cylinder 5, and a plastic cover 7 detachably installed on the outer sides of both ends of the fixed outer cylinder 4 and wrapped around the rubber block 6. Among them, a triangular support frame 301 is fixedly connected between the fixed outer cylinder 4 and the mounting frame 3, which can make the fixed outer cylinder 4 and the mounting frame 3 more stable, and can improve the safety and stability of the structure after the photovoltaic panel is installed and fixed on the mounting frame 3.

[0032] Specifically, such as Figure 1-3 As shown, the outer periphery of the fixed outer cylinder 4 is fixedly connected with multiple positioning grooves 401 arranged in a ring array and recessed inward. The side of the plastic cover 7 facing the positioning grooves 401 is fixedly connected with positioning blocks 701 that match the positioning grooves 401. The positioning grooves 401 are provided to facilitate the positioning and installation operation between the plastic cover 7 and the fixed outer cylinder 4, thereby wrapping and protecting the rubber block 6 between the fixed outer cylinder 4 and the fixed inner cylinder 5. On the other hand, it can increase the contact area between the fixed outer cylinder 4 and the rubber block 6, so that the rubber block 6 can be stably fixed between the fixed outer cylinder 4 and the fixed inner cylinder 5.

[0033] Specifically, such as Figure 1-3 As shown, the cross-sections of the cross frame 2 and the fixed inner cylinder 5 are both rectangular structures. Compared with the circular tube structure of the cross frame 2 and the fixed inner cylinder 5, this structure has better resistance to deflection, displacement, and load-bearing capacity after fixation. The left and right ends of the fixed inner cylinder 5 are fitted with fixing bolts 501 whose inner ends can abut against the outer wall of the cross frame 2 by threaded engagement. When the fixing bolts 501 abut against the cross frame 2 inward with a tool, the fixed inner cylinder 5 can be stably locked and fixed on the cross frame 2.

[0034] Among them, anti-deviation protrusions 502 are fixedly connected to the four corners of the fixed inner cylinder 5. The setting of anti-deviation protrusions 502 can increase the contact area between the fixed inner cylinder 5 and the rubber block 6. On the one hand, it reduces the occurrence of the problem of the fixed inner cylinder 5 shifting and deflecting within the rubber block 6 under force. On the other hand, it can make the rubber block 6 stably fixed between the fixed outer cylinder 4 and the fixed inner cylinder 5, which can reduce the occurrence of the problem of the rubber block 6 falling off.

[0035] Specifically, such as Figure 1-3 As shown, the rubber block 6 is made of EPDM rubber, which gives it excellent shock resistance, vibration damping, heat resistance and aging resistance. At the same time, its overall hardness and elasticity can meet the requirements of daily stable installation of photovoltaic panels, and can stably fix and bond the outer cylinder 4 and the inner cylinder 5.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, a fixing seat 101 is fixedly connected to the lower end of the ground support frame 1. The fixing seat 101 has multiple mounting holes 102. The fixing seat 101 and the mounting holes 102 are designed to facilitate the fasteners to pass through the ground support frame 1 and to fix the ground support frame 1 stably to the ground or the fixed platform.

[0037] Specifically, such as Figure 1-3 As shown, the ground support frame 1, the fixed base 101, the cross frame 2, the mounting frame 3, the triangular support frame 301, the fixed outer cylinder 4, and the fixed inner cylinder 5 are all made of aluminum alloy, which not only ensures the overall lightweight design of the photovoltaic bracket, but also makes the overall load-bearing stability, impact resistance, and corrosion resistance of the photovoltaic bracket better.

[0038] Working principle: In use, the ground support frame 1 and the mounting frame 3 can be slidably installed onto the horizontal frame 2 through the fixed inner cylinder 5. Then, using a tool, the fixing bolts 501 on the fixed inner cylinder 5 are rotated inward, and the entire fixed inner cylinder 5 can be fixed onto the horizontal frame 2. At this time, the ground support frame 1 and the mounting frame 3 can be fixed onto the horizontal frame 2, thus completing the combination and fixing operation of the aluminum alloy photovoltaic bracket. The ground support frame 1 can be fixed to the ground through the fixing seat 101 and fasteners, and the photovoltaic panel can be installed and fixed onto the mounting frame 3 through the fasteners. During daily use, when external vibration is transmitted to the ground support frame 1 or the mounting frame 3, the vibration will be transmitted upward or downward towards the horizontal frame 2. When the vibration is transmitted to the rubber block 6 between the fixed outer cylinder 4 and the fixed inner cylinder 5, the rubber block 6 can flexibly absorb and resist the vibration, thereby reducing the continued transmission of vibration and ensuring that the photovoltaic panel and photovoltaic bracket can operate normally.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
