Description

Technical Field

[0001] The utility model relates to the field of bottom support devices for photovoltaic grid frames, in particular to a bottom support structure for assembling photovoltaic grid frames. Background Art

[0002] A solar photovoltaic bracket is a special bracket designed to place, install, and fix solar panels in a solar photovoltaic power generation system. Generally, the materials are aluminum alloy, carbon steel, and stainless steel.

[0003] A conventional bottom support structure for assembling a photovoltaic grid frame generally uses a welding method for connection. The support structure is placed on a slider and transported along a slide rail. The direct welding method makes it extremely inconvenient to disassemble the support structure from the photovoltaic grid frame, and additional cutting is required. Or there may be deviations when welding the support structure to the photovoltaic grid frame, which easily damages the photovoltaic grid frame. Therefore, a conventional detachable support structure is used. Since different photovoltaic grid frames have different grid spacings, and the conventional detachable support structure is not convenient to adjust the spacing to adapt to photovoltaic brackets with different grid spacings. Therefore, a bottom support structure for assembling a photovoltaic grid frame is needed to conveniently adjust the bottom support structure. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bottom support structure for assembling a photovoltaic grid frame that can conveniently adjust the bottom support structure.

[0005] The technical solution to achieve the above purpose is: A bottom support structure for assembling a photovoltaic grid frame includes a first bottom plate. A slide plate is connected to the side wall of the first bottom plate. Two symmetrically distributed first screw rods are threadedly connected to the side wall of the first bottom plate. A second bottom plate is rotatably connected to the side wall of the first screw rod. A sliding hole is opened at the bottom end of the second bottom plate. The inner side wall of the sliding hole is slidably connected to the slide plate. Adjusting members are arranged at the top ends of the first bottom plate and the second bottom plate, and a limiting member is arranged on the adjusting member.

[0006] Preferably, the adjusting member includes a bottom tube, a bracket, an inner rod, a second screw rod, and a threaded hole. Two symmetrically distributed bottom tubes are connected to the top ends of the first bottom plate and the second bottom plate. Brackets are connected to the top ends of the first bottom plate and the second bottom plate. A threaded hole is opened at the top end of the bracket. The inner rod is slidably connected to the inside of the bottom tube. The second screw rod is threadedly connected to the side wall of the threaded hole.

[0007] Preferably, the limiting member includes a connecting plate, a top plate, screws, arc-shaped holes and nuts. A connecting plate is connected to the top end of the inner rod. A top plate is placed on the top end of the connecting plate. Arc-shaped holes are formed in the side walls of both the connecting plate and the top plate. A plurality of screws are threadedly connected to the side walls of both the connecting plate and the top plate. Nuts are threadedly connected to the side walls of the screws. The top end of the second screw rod is rotatably connected to the connecting plate.

[0008] Preferably, a rubber pad is connected inside the arc-shaped hole.

[0009] Preferably, the length of the connecting plate is equal to the length of the top plate, the length of the first bottom plate is equal to the length of the second bottom plate, and the length of the connecting plate is less than the length of the first bottom plate.

[0010] Preferably, a screw tube is connected to the side wall of the connecting plate. A limiting screw rod is threadedly connected inside the screw tube. One end of one of the limiting screw rods is connected to a first round rod, and one end of the other limiting screw rod is connected to a second round rod. The first round rod is in damping sliding connection with the second round rod.

[0011] Preferably, the diameter of the screw tube is less than the height of the connecting plate.

[0012] Preferably, the sum of the lengths of the first round rod and the second round rod is less than the sum of the widths of the sliding plate and the second bottom plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1) Rotate the first screw rod. The first screw rod drives the second bottom plate to move, thereby reducing the distance between the first bottom plate and the second bottom plate, and further reducing the distance between the adjusting members, so as to achieve the adaptation of the adjusting members to the grid size of the photovoltaic grid frame. By using the adjusting members and the limiting members, the photovoltaic grid frame can be clamped, achieving the effect of convenient installation and disassembly.

[0015] 2) When the second bottom plate moves, it drives the inner rod to move through the bracket and the bottom tube. The inner rod drives the connecting plate to move, and then adjusts the distance between the two connecting plates to adapt to the grid size of the photovoltaic grid frame. Rotate the second screw rod. The second screw rod drives the connecting plate to move upward to adjust the placement height of the photovoltaic grid frame. Place the photovoltaic grid frame in the arc-shaped hole on the connecting plate, cover the top plate on the connecting plate, screw in the screws, and tighten the nuts so that the nuts are closely attached to the connecting plate, thereby clamping the photovoltaic grid frame by the top plate and the connecting plate. Just perform the above operations in reverse to disassemble the top plate, which facilitates the disassembly and separation between the photovoltaic grid frame and the support base.
