Description

Technical Field

[0001] This application relates to the field of photovoltaic panel support technology, specifically a shockproof structure for photovoltaic power generation support. Background Technology

[0002] Photovoltaic power generation, as a clean, environmentally friendly, and sustainable energy form, has been widely used in recent years. In photovoltaic power generation systems, the support structure, as an important component supporting the photovoltaic panels, directly affects the overall efficiency and service life of the photovoltaic power generation system. Traditional photovoltaic power generation supports are generally made of metal materials such as steel and are fixed to the ground or building structure through welding, bolting, and other methods.

[0003] However, in practical applications, especially in areas where natural disasters such as wind and earthquakes are frequent, traditional support structures are easily subjected to strong vibrations and impacts, which can affect the stability of photovoltaic panels and even lead to damage to the photovoltaic panels or failure of the photovoltaic power generation system.

[0004] Therefore, this application provides a shockproof structure for photovoltaic power generation support to solve the above problems. Utility Model Content

[0005] This application provides a shock-resistant structure for photovoltaic power generation brackets, aiming to solve the problem mentioned in the background art that existing photovoltaic power generation brackets lack shock-resistant structures and are easily damaged in areas where natural disasters such as wind and earthquakes are frequent.

[0006] To achieve the above objectives, this application provides the following technical solution: a shockproof structure for a photovoltaic power generation bracket, comprising a base with relatively distributed components and a first leg and a second leg equidistantly mounted on the base. A connecting frame rod and a fixed rail rod relatively mounted on the connecting frame rod are fixedly mounted on the first leg and the second leg. An assembly seat is provided on the fixed rail rod, and a photovoltaic power generation panel is provided on the assembly seat.

[0007] A crossbar is installed between the two connecting frame rods, and a shock-absorbing mechanism is provided on the crossbar;

[0008] The vibration damping mechanism includes a fixed base fixedly installed at the lower end of the crossbar. The lower end of the fixed base is provided with a positioning rod connected to the base. A damper is fixedly installed at the upper end of the positioning rod. The piston end of the damper is fixedly connected to the lower end of the fixed base. A first spring sleeved with the damper is provided between the fixed base and the positioning rod, forming the main support structure of the bracket. Through the parallel structure of the damper and the spring, vibration attenuation is achieved, protecting the photovoltaic power generation panel from severe vibration.

[0009] Preferably, the upper end of the crossbar is fitted with a purlin support plate connected to the connecting frame rod, which increases the connection stiffness between the crossbar and the connecting frame rod, helps to disperse vibration loads, and prevents local stress concentration.

[0010] Preferably, a positioning seat is fitted on the positioning rod, and movable rods are hinged to both ends of the positioning seat. An adjustment seat is symmetrically installed at the lower end of the mounting seat, and a slider is slidably connected to the lower end of the adjustment seat. The slider is hinged to the end of the movable rod away from the positioning rod, thus constructing a horizontal vibration reduction transmission path. Through the hinged structure of the movable rod, horizontal vibration is converted into linear motion of the slider, which, in conjunction with the damper, achieves multi-dimensional vibration reduction.

[0011] Preferably, a guide rod that passes through the slider is fixedly installed inside the adjusting seat, and a second spring connected to the slider is sleeved on the outside of the guide rod.

[0012] Preferably, the positioning rod has a plurality of positioning holes equidistantly spaced, and the positioning seat is fixedly connected to the positioning holes on the positioning rod by bolts.

[0013] This anti-vibration structure is connected to the fixed seat through the piston end of the damper. The first spring is sleeved outside the damper. When the support is vibrated, the damper absorbs the kinetic energy and the spring provides elastic restoring force to reduce the up-and-down vibration of the crossbar. The damper is a hydraulic damper with a damping coefficient that is adapted to the entire photovoltaic panel support and can absorb the corresponding vibration energy. The first spring can adapt to the vibration frequency and effectively reduce the risk of resonance. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This embodiment provides a shock-resistant structure for photovoltaic power generation brackets, such as... Figure 1-4 As shown, the anti-vibration structure includes a base 1 that is relatively distributed and a first leg 2 and a second leg 24 that are equidistantly installed on the base 1. A connecting frame rod 23 and a fixed rail rod 21 that are relatively installed on the connecting frame rod 23 are fixedly installed on the first leg 2 and the second leg 24. An assembly seat 22 is provided on the fixed rail rod 21, and a photovoltaic power generation panel 25 is provided on the assembly seat 22.

[0022] A crossbar 31 is installed between the two connecting rods 23, and a shock-absorbing mechanism 3 is provided on the crossbar 31;

[0023] The shock-absorbing mechanism 3 includes a fixed seat 324 fixedly installed at the lower end of the crossbar 31. The lower end of the fixed seat 324 is provided with a positioning rod 32 connected to the base 1. The upper end of the positioning rod 32 is fixedly installed with a damper 322. The piston end of the damper 322 is fixedly connected to the lower end of the fixed seat 324. A first spring 323 is provided between the fixed seat 324 and the positioning rod 32 and sleeved with the damper 322.

[0024] Specifically, the base 1 supports the connecting rod 23 via the first leg 2 and the second leg 24. The fixed rail 21 and the mounting base 22 fix the photovoltaic panel 25. In the anti-vibration mechanism 3, the piston end of the damper 322 is connected to the fixed base 324. The first spring 323 is sleeved on the outside of the damper 322. When the support is vibrated, the damper 322 absorbs the kinetic energy, and the spring provides elastic restoring force to reduce the up-and-down vibration of the crossbar 31. The damper 322 is a hydraulic damper 322. The damping coefficient is adapted to the entire photovoltaic panel support and can absorb the corresponding vibration energy. The first spring 323 can adapt to the vibration frequency and effectively reduce the risk of resonance. The gap between the fixed base 324 and the positioning rod 32 is greater than the length of the damper 322 to ensure the coaxiality of the piston movement of the damper 322 and avoid the efficiency reduction caused by the off-center load. The damper 322 is a one-way hydraulic damper 322.

[0025] The upper end of the crossbar 31 is fitted with a purlin support plate 36 that is connected to the connecting frame rod 23.

[0026] More specifically, the purlin support plate 36 connects the crossbar 31 and the connecting frame rod 23, evenly transferring the load of the anti-vibration mechanism 3 to the main body of the support, enhancing the lateral stability of the crossbar 31. The symmetrically distributed purlin support plates 36 ensure that the crossbar 31 is subjected to balanced forces on both sides, reducing the lateral deformation of the support.

[0027] A positioning seat 33 is fitted on the positioning rod 32. Movable rods 34 are hinged to both ends of the positioning seat 33. Adjusting seats 35 are symmetrically installed at the lower end of the assembly seat 22. A slider 353 is slidably connected to the lower end of the adjusting seat 35. The slider 353 is hinged to the end of the movable rod 34 away from the positioning rod 32.

[0028] Furthermore, the positioning seat 33 is hinged to the slider 353 via the movable rod 34. When the photovoltaic panel 25 is subjected to horizontal vibration, the slider 353 slides along the adjusting seat 35, and the movable rod 34 drives the positioning seat 33 to move on the positioning rod 32 to absorb the horizontal vibration energy. The sliding friction coefficient between the slider 353 and the adjusting seat 35 is ≤0.15, ensuring sensitive response and no jamming during vibration.

[0029] The inside of the adjusting seat 35 is fixedly installed a guide rod 351 that passes through the slider 353, and the outside of the guide rod 351 is fitted with a second spring 352 that is connected to the slider 353.

[0030] It should be noted that the guide rod 351 restricts the movement direction of the slider 353, and the second spring 352 provides elastic support in the horizontal direction. When the slider 353 slides, the spring absorbs and stores energy, and releases energy to reset when the vibration weakens. The guide rod 351 is plated with hard chrome, which has high hardness and strong wear resistance.

[0031] The positioning rod 32 has several positioning holes 321 at equal intervals, and the positioning seat 33 is fixedly connected to the positioning holes 321 on the positioning rod 32 by bolts.

[0032] It is worth mentioning that the positioning holes 321 are evenly distributed along the positioning rod 32, and the installation height of the positioning seat 33 can be adjusted by bolts to accommodate photovoltaic panels 25 of different specifications.

[0033] In use, the piston end of the damper 322 is connected to the fixed seat 324. The first spring 323 is sleeved on the outside of the damper 322. When the support is vibrated, the damper 322 absorbs the kinetic energy, and the spring provides elastic restoring force to reduce the up and down vibration of the crossbar 31. The damper 322 is a hydraulic damper with a damping coefficient that is adapted to the entire photovoltaic panel support and can absorb the corresponding vibration energy. The first spring 323 can adapt to the vibration frequency and effectively reduce the risk of resonance.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
