Description

Technical Field

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

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of independent operation and grid-connected operation. Photovoltaic brackets are used to support photovoltaic panels and play a vital role. Some adopt counterweight blocks placed on the brackets to increase the stability of the brackets when placed. The announcement number is CN215581042U, which discloses a mountain counterweight stable photovoltaic bracket. Its technical solution includes: a support frame and a mounting frame arranged on the support frame, the mounting frame is provided with a photovoltaic panel, fixed blocks are arranged on both sides of the photovoltaic panel, a sliding rod is arranged between the fixed blocks, and a slider is arranged on the rod body of the sliding rod. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved: the device only fixes the support frame to the ground by a fixed rod, but when the ground soil is relatively loose, the stability of the connection between the fixed rod and the ground is not good, which can easily affect the stability of the support frame supporting the photovoltaic panel.

[0003] The publication (announcement) number is CN219893209U, which discloses a counterweight-stabilized photovoltaic bracket, including a support mechanism, which includes a support frame, a load-bearing plate, a clamping assembly, a photovoltaic panel, a rotating rod and a transmission assembly, wherein the load-bearing plate is fixedly connected to the top surface of the support frame, the clamping assembly is arranged on the side of the load-bearing plate, the photovoltaic panel is arranged on the top surface of the load-bearing plate, and the side of the clamping assembly abuts against the side of the photovoltaic panel. The utility model presses the load-bearing assembly and the first tooth plate downward by the counterweight block, and the gear rod is driven to move by the first tooth plate, and then the limit assembly is driven to move and pop out from the conical nail by the gear rod, so as to increase the possibility of separation of the conical nail from the ground, thereby increasing the stability of the support frame supporting the photovoltaic panel; the transmission assembly and the clamping assembly are driven to operate by rotating the rotating rod, and then the photovoltaic panel is easily fixed on the load-bearing plate by the clamping assembly, so that the photovoltaic panel is more convenient to assemble.

[0004] Although the above scheme makes it more convenient to assemble photovoltaic panels and increases the stability of photovoltaic panel support, the inclination angle of the photovoltaic panel on the bracket is fixed after it is fixed, and it is difficult and laborious for personnel to adjust and maintain the photovoltaic panel. In addition, the clamping assembly of the photovoltaic panel requires the cooperation of transmission parts such as rotating rods, pulleys, and belts. The equipment has a complex limiting structure for the photovoltaic panel and a high preparation cost. For this reason, we propose a photovoltaic counterweight bracket. Utility Model Content
