Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic panel auxiliary installation equipment, and in particular relates to a seismic-resistant flexible connection structure for multiple connections of photovoltaic panels. Background Art

[0002] At present, photovoltaic equipment has entered thousands of households, thanks to the continuous progress of photovoltaic technology and the continuous improvement of the efficiency of photovoltaic modules. At the same time, the increasing maturity of technologies such as energy storage and microgrids has provided strong support for the further development of distributed photovoltaics. With technological progress and large-scale production, the cost of photovoltaic systems has continued to decrease, and grid parity has gradually been achieved, and the dependence on subsidies has gradually decreased. This makes photovoltaic systems more competitive in the market and attracts more users to install them.

[0003] Since the size and specifications of photovoltaic panels have been determined when they leave the factory, installation requires that several photovoltaic panels be spliced ​​together in a vertical and horizontal distribution. In addition, the installed photovoltaic panels are made up of several groups that try to cover the installation area, such as the entire roof, the entire factory building, etc. If each photovoltaic panel is rigidly connected, then in the event of a strong earthquake, the torsional force will cause partial damage to the photovoltaic panels, which will not only cause property loss, but will also be very troublesome to replace. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a seismic-resistant flexible connection structure for multiple connections of a photovoltaic panel, in which a buckling piece is fixed to a fixing piece by a stud, and a longitudinal elastic deformation space is provided by a first spring on the stud, and a transverse elastic deformation space is provided by a second spring in a plug-in portion and a plug-in groove, so that the photovoltaic panel has a structure for flexible twisting under torsional force, thereby avoiding damage to the photovoltaic panel due to vibration.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A seismic-resistant flexible connection structure with multiple connections of a photovoltaic panel, comprising a fixing, a buckling piece, a stud, a photovoltaic panel and an elastic component, wherein a concave pressing tube is connected to the outer side wall of the fixing member, and the upper end face of the pressing tube is abutted against the lower end face of the photovoltaic panel; the buckling member is a T-shaped structure with a lower end face extending downward to form a plug-in portion, and left and right ends extending outward to form a buckling portion, the plug-in portion is cooperatively connected to the plug-in groove on the upper end face of the fixing member, the outer side wall of the plug-in portion is abutted against the inner side wall of the plug-in groove, a through hole is provided on the upper end face of the buckling member, the stud passes through the through hole and is screwed into the screw hole at the bottom of the plug-in groove, and the lower end face of the buckling portion is abutted against the upper end face of the photovoltaic panel; the elastic component comprises a first spring and a second spring, the first spring is sleeved on the stud, the upper end face of the first spring abuts against the nut on the top of the stud, and the lower end face of the first spring abuts against the buckling member.

[0007] A first card slot is provided on the outer wall of the plug-in portion, and a second card slot is provided on the inner wall of the plug-in slot, the first card slot and the second card slot correspond to each other, and the two ends of the second spring are respectively embedded in the first card slot and the second card slot; the first card slot and the second card slot include a plurality of groups, and the plurality of groups of the first card slots are symmetrically distributed on the left and right end surfaces outside the plug-in portion; the plurality of groups of the second card slots are symmetrically distributed on the left and right end surfaces inside the plug-in slot; a plurality of first tooth slots are provided on the outer wall of the plug-in portion, and a plurality of second tooth slots are provided on the inner wall of the plug-in slot, and the first tooth slots and the second tooth slots are abutted and connected.

[0008] The photovoltaic panel with multiple connections adopts this structure. The pressure tube at the bottom of the fixing part abuts against the bottom of the photovoltaic panel, the buckling part extending outward on the buckling part abuts against the top of the photovoltaic panel, the stud is inserted into the through hole on the buckling part, and the end of the stud is screwed into the screw hole on the bottom of the plug-in slot, thereby fixing the photovoltaic panel. Since this connection method is a rigid connection, a first spring is sleeved on the stud, one end of the first spring abuts against the nut of the stud, and the other end of the first spring abuts against the buckling part. Therefore, in the process of gradually tightening the stud, the pressure of the first spring on the buckling part will increase, thereby maintaining the longitudinal pressure on the photovoltaic panel. When the photovoltaic panel is subjected to longitudinal torsional force, the compression spring can be used to deform, so that the photovoltaic panel will not be damaged by longitudinal distortion due to the rigid connection.

[0009] In order to be able to perform elastic compression deformation in the lateral direction, the plug-in portion is first matched in the plug-in slot on the fixing member, and the width of the plug-in portion is slightly smaller than the inner width of the plug-in slot, so that the buckling member can have space to move horizontally to the left and right after being inserted into the plug-in slot through the plug-in portion. In order to achieve elastic compression deformation, a first card slot is provided on the outer side wall of the plug-in portion, and a second card slot is provided on the inner side wall of the plug-in slot. The second spring is provided in the first card slot and the second card slot corresponding to each other. Since the plug-in portion is to be moved horizontally to the left and right, a plurality of groups of first card slots and second card slots are provided. And they are symmetrically distributed on the plug-in part and the plug-in slot, so that the plug-in part can move horizontally left and right in the plug-in slot under the elastic force of the second spring. In order to ensure that the photovoltaic panels are pushed horizontally when they move horizontally, and to avoid longitudinal movement during the horizontal pushing process and causing the photovoltaic panels in the middle to detach, a first tooth groove is set on the plug-in part, and a second tooth groove is set on the inner wall of the plug-in slot. The first tooth groove corresponds to the second tooth groove, so when the second spring is compressed and deformed under pressure, the first tooth groove will be inserted into the second tooth groove, thereby limiting the longitudinal displacement.

[0010] Furthermore, an accommodating groove is provided on the upper end surface of the buckling piece, and the through hole is arranged in the accommodating groove.

[0011] Compared with the prior art, the advantages of the utility model are: the buckling piece is locked on the fixing piece by the stud to press the photovoltaic panel, and the first spring is sleeved on the stud to maintain the longitudinal pressure on the photovoltaic panel. When the photovoltaic panel is subjected to longitudinal torsional force, it can be deformed by the compression spring, so that the photovoltaic panel will not be twisted and damaged in the longitudinal direction due to the rigid connection. A second spring is provided between the plug-in part and the plug-in slot. Under the elastic force of the second spring, the plug-in part can move horizontally left and right in the plug-in slot, realizing elastic compression deformation in the lateral direction. The additional first tooth groove and the second tooth groove can limit the longitudinal displacement during the lateral movement, so as to avoid the middle photovoltaic panel from being dislocated and falling out during the lateral displacement of the continuous photovoltaic panels. Finally, the structure realizes the flexible connection between the photovoltaic panels, so that there is still sufficient anti-twisting effect between the photovoltaic panels in the case of strong vibration, thus avoiding the damage of the photovoltaic panels caused by the rigid connection.
