Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation brackets, in particular to a buffer bracket for photovoltaic power generation. Background Art

[0002] The mounting bracket of solar photovoltaic panels is a frame structure made of metal or alloy materials, usually made of aluminum alloy, stainless steel or galvanized steel. The design of this bracket structure mainly considers factors such as wind resistance, earthquake resistance and durability to ensure that the photovoltaic panels can be firmly installed and operate for a long time under various environmental conditions. Some mounting brackets are also designed with adjustable angles, so that the tilt angle of the photovoltaic panels can be adjusted according to the local longitude and latitude and seasonal changes to maximize the capture of solar radiation;

[0003] For example, a buffer bracket for photovoltaic power generation that is easy to install is disclosed in the authorization announcement number CN216414230U, which includes a support column, a base is fixedly installed at the bottom of the support column, a telescopic rod is fixedly installed inside the support column, a linear guide is fixedly installed on the top of the telescopic rod, a mounting block is provided on the outer surface of the linear guide, a spring is fixedly installed on one side of the mounting block, a slider is provided on one side of the spring, a slide rail is fixedly installed on one side of the support column, a cylinder is provided on the other side of the mounting block, a sleeve is fixedly installed on one side of the support column, a telescopic rod B is fixedly installed inside the sleeve, etc., which places the photovoltaic panel on the top of the mounting plate, pushes the spring telescopic column through the groove at the bottom of the mounting plate to fix it, pushes it into the circular groove, and the baffle plate resists the spring telescopic column to prevent it from moving, thereby achieving a fixing effect. However, the buffering and shock-absorbing effect of the photovoltaic panel is mainly achieved through the spring telescopic rod in this technical solution, which can only provide limited shock-absorbing capacity. When encountering strong winds or other external impacts, the spring telescopic rod is difficult to provide sufficient buffering force, resulting in greater vibration of the photovoltaic panel. Utility Model Content

[0004] The purpose of the utility model is to provide a buffer bracket for photovoltaic power generation, which enables two multi-point back frames arranged opposite to each other to obtain a buffer function through a damping shock absorber and a double pull rod connection structure, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a buffer bracket for photovoltaic power generation, comprising a circular hollow vertical frame and a U-shaped outward expansion frame fixed on the outer walls on both sides of the circular hollow vertical frame, two symmetrical cross bars are rotatably installed between the two U-shaped outward expansion frames, connecting plates are fixed at both ends of the surface of the cross bars, a multi-point back frame is installed on the outer wall of one side of the two connecting plates in the same X-axis direction, a double pull rod connection structure is provided on the outer wall of one side of the circular hollow vertical frame on one side of the U-shaped outward expansion frame, the double pull rod connection structure is used to connect the two connecting plates in the Y-axis direction, a damping shock absorber is hinged on the outer wall of one side of the U-shaped outward expansion frame, and the top end of the piston rod of the damping shock absorber is connected to the movable end of the double pull rod connection structure.

[0006] Preferably, a double-layer reinforcement arm is welded to one side of the bottom of the circular hollow vertical frame.

[0010] Preferably, the circular hollow vertical frame, the double-layer reinforcement arm and the U-shaped external expansion frame are all made of stainless steel.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the buffer bracket for photovoltaic power generation is provided with a double pull rod connection structure and a damping shock absorber and other structures that cooperate with each other. When the solar photovoltaic panel encounters external impacts such as external strong winds, the solar photovoltaic panel, the multi-point back frame and the connecting plate will flip with the cross bar as the center of the circle, so that the double pull rod connection structure will contract, and then the damping shock absorber will be stretched and extended, and the lower cylinder of the damping shock absorber will swing to a certain extent. In this process, the damping effect of the damper itself and the stable support of the double pull rod structure can effectively absorb and disperse the external impact force on the photovoltaic panel, thereby reducing the vibration amplitude and protecting the photovoltaic panel from damage.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0018] Please refer to Figures 1-4 , an embodiment provided by the present utility model: A buffer bracket for photovoltaic power generation includes a loop - shaped hollow vertical frame 1 and U - shaped outward - expanding frames 2 fixed on the outer walls on both sides of the loop - shaped hollow vertical frame 1. Two symmetric cross - bars 3 are rotatably installed between the two U - shaped outward - expanding frames 2. Connecting plates 4 are fixed at both ends of the surface of the cross - bar 3. A multi - point back frame 5 is installed on the outer wall of one side of the two connecting plates 4 in the same X - axis direction. A double - tie rod connection structure 6 is provided on the outer wall of one side of the loop - shaped hollow vertical frame 1 on one side of the U - shaped outward - expanding frame 2. The double - tie rod connection structure 6 is used to connect the two connecting plates 4 in the Y - axis direction. A damping shock absorber 7 is hinged on the outer wall of one side of the U - shaped outward - expanding frame 2. The top end of the piston rod of the damping shock absorber 7 is connected to the movable end of the double - tie rod connection structure 6. This bracket can synchronously install two oppositely - facing photovoltaic panels, and in this process, the buffer and shock - absorption effects are achieved by one or two damping shock absorbers 7. Its structure is simple, the work is stable and reliable, and the structural durability of the damping shock absorber 7 is better than that of a spring telescopic rod, and it can resist factors such as sunlight, rain, wind and sand erosion, and maintain stable shock - absorption effects and connection performance;

[0019] On one side of the bottom of the loop-shaped hollow vertical frame 1, a double-layer reinforcing arm 101 is welded. The loop-shaped hollow vertical frame 1, the double-layer reinforcing arm 101, and the U-shaped outward expansion frame 2 are all made of stainless steel. Components such as the loop-shaped hollow vertical frame 1, the double-layer reinforcing arm 101, and the U-shaped outward expansion frame 2 need to bear the weight of the photovoltaic panel and loads such as wind force brought by the external environment. Using stainless steel can ensure the structural stability of the components;

[0020] The multi-point back frame 5 includes a cross beam 501 fixed between two connecting plates 4, and a backing plate 502 installed on the surface of the cross beam 501. Inverted L-shaped flanges 503 are provided at the top and bottom of the backing plate 502. A number of equally spaced vertical arms 504 are fixed on the surface of the inverted L-shaped flanges 503. A number of through holes are provided at both ends of the surface of the vertical arms 504;

[0021] The back frame of the solar photovoltaic panel is attached to a plurality of vertical arms 504, and the vertical arms 504 and the back frame of the photovoltaic panel can be bolted. The multi-point back frame 5 and the photovoltaic panel are connected by a plurality of connection points. Compared with single-point connection, the connection stability and firmness of the two can be increased, and the installation pressure on the photovoltaic panel can be effectively dispersed;

[0022] The double-tie rod connection structure 6 includes a right-angle seat 601 fixed on the outer wall of one side of the loop-shaped hollow vertical frame 1, and a rotating shaft 602 rotatably installed on the surface of the right-angle seat 601. A rotating arm 603 is fixed at the top of the rotating shaft 602. Link monomers 604 are hinged at both ends of the surface of the rotating arm 603. One end of the link monomer 604 away from the rotating shaft 602 is hinged to the top of the connecting plate 4;

[0023] When the connecting plate 4 and the multi-point back frame 5 are driven to deflect by external factors, the connecting plate 4 will push the link monomer 604 towards the direction of the rotating shaft 602, so that the rotating shaft 602 and the rotating arm 603 rotate clockwise. Then the damping shock absorber 7 is stretched under the rotation of the rotating arm 603, and the damping effect of the damping shock absorber 7 during this process prevents the rotation of the rotating shaft 602 and the rotating arm 603 to achieve a more stable buffering effect for components such as the connecting plate 4 and the multi-point back frame 5.

[0024] When the embodiment of the present application is in use, first, the staff takes out the solar photovoltaic panel to be used, and fixes the back frame of the solar photovoltaic panel to the multi-point back frame 5, that is, connects them by bolting, so as to complete the connection operation between the bracket and the solar photovoltaic panel. At this time, two solar photovoltaic panels are arranged oppositely on the bracket. When the solar photovoltaic panel encounters external impacts such as strong winds, the solar photovoltaic panel, the multi-point back frame 5 and the connecting plate 4 will rotate around the cross bar 3, so that the double tie rod connection structure 6 contracts, and then the damping shock absorber 7 is stretched and extended, and the lower cylinder body of the damping shock absorber 7 swings by a certain amplitude. During this process, through the self-damping effect of the damper and the stable support of the double tie rod structure, the external impact force received by the photovoltaic panel can be effectively absorbed and dispersed, thereby reducing the vibration amplitude, protecting the photovoltaic panel from damage, and maintaining the stability of the photovoltaic panel system.

[0025] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
