Description

Technical Field

[0001] The utility model relates to the field of photovoltaic supports, in particular to a photovoltaic bracket. Background Art

[0002] Because photovoltaic brackets need to be adjusted, the middle of the photovoltaic supporting beams and the upright columns in the prior art are hinged, and the left and right sides of the support plate are connected to the two sides of the foundation pile. In this way, the columns are subjected to large forces and are easily damaged. For example, the Chinese utility model patent "An Adjustable Photovoltaic Bracket Device" with application number CN202121724186.7. This structural instability problem further brings about the problem that the adjustable angle of the support member is too small. If the adjustment is too large, the support plate will be seriously tilted to the left or right side of the column relative to the column, and the force on the column will be seriously unbalanced. In addition, after the angle is adjusted, the bracket only relies on the rotation mechanism to limit the rotation, and has no positioning function.

[0003] Therefore, a photovoltaic support with a stable structure is needed. Utility Model Content

[0013] The stretching device is used to adjust the angle of the support assembly relative to the column, and the locking device is used to lock the support assembly after the angle is adjusted to the column.

[0014] Furthermore, the locking device includes at least one positioning rod located on the rod BC, and the positioning rod is perpendicular to the rod BC;

[0015] When the truss rotates to the right relative to the column, the positioning rod is stuck on the right side of the foundation pile to limit the rod BC from moving to the left; or when the truss rotates to the left relative to the column, the positioning rod is stuck on the left side of the foundation pile to limit the rod BC from moving to the right.

Similar expressions are only for illustrative purposes, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] like Figure 1-2 A photovoltaic support shown includes a foundation pile 1, a column 2, a stretching device 3, a support assembly, and a locking device 5.

[0030] The column 2 is erected on the top of the foundation pile 1; the erected foundation pile 1 and the column 2 are used to firmly fix the photovoltaic support to the ground.

[0031] The support assembly includes a truss 4, a right support rod 6, a left support rod 7 and a truss 8; the support assembly is used to connect the photovoltaic to the foundation pile 1 and the column 2.

[0032] The photovoltaic is fixed on the sandalwood bar 8; the sandalwood bar 8 is used to fix and support the photovoltaic, and the truss 4, the right support rod 6, and the left support rod 7 are used to support the sandalwood bar 8.

[0033] The truss 4 is a triangular frame and includes rods AB, BC and CA fixed in sequence; rods AB and CA are respectively hinged to the top of the column 2 at point A, that is, the column 2 and the truss 4 are hinged at the vertex A of the triangular frame, and rod BC is located below point A due to gravity; the rails 8 are fixed to the truss 4 at point A.

[0034] The left support rod 7 and the right support rod 6 are respectively located on the left and right sides of the truss 4. One end of the right support rod 6 is hinged or fixedly connected to one side and the right side of the crossbar 8, and the other end of the right support rod 6 is fixed or hinged to the rod BC at point C; one end of the left support rod 7 is fixedly connected or hinged to the other side and the left side of the crossbar 8, and the other end of the left support rod 7 is fixed or hinged to the rod BC at point B. The truss 4 has three support points from right to left, namely, one end of the right support rod 6, the vertex A of the truss 4, and one end of the left support rod 7. The left support rod 7 and the right support rod 6 can be connected to the crossbar by bolts respectively. The support assembly supports the crossbar 8 through multiple triangular structures. In addition to the triangular structure provided by the truss 4, the crossbar 8, the right support rod 6 and the rod CA form a triangular structure, and the crossbar 8, the left support rod 7 and the rod AB form a triangular structure.

[0035] The fixed end of the tensioning device 3 is hinged to the side of the foundation pile 1, preferably the left side or right side of the foundation pile 1. The telescopic end of the tensioning device 3 is hinged to the truss 4 at point C.

[0036] The stretching device 3 is used to adjust the angle of the support assembly relative to the column 2, and the locking device 5 is used to lock the support assembly after the angle adjustment to the column 2. The rod BC rotates relative to the column 2, thereby changing the angle of the sandalwood bar 8.

[0037] Preferably, the locking device 5 includes at least one positioning rod located on the rod BC, and the positioning rod is perpendicular to the rod BC; the number of the locking devices 5 varies according to the number of angles that need to be adjusted.

[0038] When the truss 4 rotates clockwise relative to the column 2, the positioning rod is stuck on the right side of the foundation pile 1 to limit the rod BC from moving to the left; or when the truss 4 rotates counterclockwise relative to the column 2, the positioning rod is stuck on the left side of the foundation pile 1 to limit the rod BC from moving to the right.

[0039] Preferably, the positioning rod is an elastic positioning pin. Elastic positioning pins are prior art, as described in Chinese Utility Model Patent Application No. CN202021269958.8, "An Elastic Latch," Chinese Utility Model Patent Application No. CN202020264401.9, "An Elastic Positioning Pin Mechanism," and Chinese Utility Model Patent Application No. CN202021429294.7, "An Elastic Positioning Pin with Floating Support Function." The elastic positioning pin is mounted on the truss 4. When positioning is required, the removable pin of the elastic positioning pin extends out of the truss 4. When positioning is not required, the pin retracts into the truss 4.

[0040] Preferably, the number of positioning rods is 2. Figure 1-2 As shown, general photovoltaic brackets require adjustment at two angles. Figure 1The rightward rotation angle of the inner sandalwood bar 8 is small, the truss 4 rotates to the right, and the left elastic positioning pin on the rod BC is stuck on the outside of the right side of the column 2, preventing the rod BC from resetting to the left; Figure 2 The inner truss 4 rotates to the left, and the right elastic positioning pin on the rod BC is stuck on the outside of the left side of the column 2 to prevent the rod BC from resetting to the right.

[0041] A circular tube truss is used as the main axis. Since the truss is a triangular structure, the structure is stable; the characteristics of the supporting two-force rod are repeatedly utilized to form a triangular stability system; the supporting angle is increased to fully form a triangular stability system; and a spring-loaded latch device is provided to allow the bracket to be completely fixed using the spring-loaded latch when it reaches the designed angle.

[0042] first Figure 1 When the angle is small, the right side of the truss is close to the column, and the elastic positioning pin is clamped to the column; Figure 2 When the angle is large, the left side of the truss is in close contact with the column, and the elastic locating pin is clamped with the column; then the right support rod 6 forms a stable structural system through the truss and the tan bar. Similarly, the left support rod forms a stable structural system through the truss and the tan bar. The stretching device and the truss 4 are connected by a rotatable bearing, and the overall structure is driven to rotate by the stretching of the stretching device 3. The truss can be made into standard parts according to the spacing between the brackets and connected by bolts. The truss is used as the main axis. Since the truss is a triangular structure, the structure is stable and the truss is clearly stressed and the force transmission is accurate, so that each component can play its full role, ensuring structural stability while ensuring economy. The tan bar and the left and right support rods form a stable triangular system.

[0043] Preferably, the positioning rod is a screw, which is detachably connected to the rod BC. The rod BC is provided with multiple screw holes for receiving the screw. This allows the screw to be installed on the truss 4 using a selected screw hole as needed. The screw protrudes from the truss 4, forming a right angle with the truss 4, and can partially surround the column 2, thereby achieving positioning of the truss 4 and the column 2.

[0044] Preferably, the stretching device 3 is a hydraulic cylinder.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
