Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a ground connection structure for photovoltaic supports. Background Technology

[0002] Solar energy resources are abundant and widely distributed. As a clean energy source, it is the most promising renewable energy source. With the increasing prominence of global energy shortages and environmental pollution, its exploitation and utilization are receiving increasing attention from countries worldwide. Utilizing solar photovoltaic power generation technology to create clean and renewable energy for humanity is a major future trend and has become a new energy industry of widespread concern and key development for countries around the world.

[0003] To collect large amounts of solar energy, photovoltaic (PV) systems need to be installed on vast areas of land. Existing methods for connecting PV systems to ground stakes are relatively simple, often involving inserting the support columns of the PV system into the stakes and connecting them with bolts that pass vertically through. When PV systems are located in high-altitude, windy areas, strong winds can easily cause connections to loosen, support columns to twist and deform, leading to changes in the tilt angle of the PV panels, or even the entire PV system being overturned. This affects power generation efficiency and the lifespan of the PV system, necessitating further improvements. Utility Model Content

[0004] The purpose of this invention is to provide a ground connection structure for photovoltaic brackets to solve the problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: A ground connection structure for a photovoltaic support system includes a support column, with a photovoltaic panel mounting frame connected to the top of the support column. The support column includes a front column and a rear column, with the front column being lower than the rear column. A sleeve is provided on the outer side of the lower end of the support column, and the sleeve is connected to the support column by a first bolt. A first flange is fixedly connected to the bottom of the sleeve, and the first flange is detachably connected to a helical pile. The helical pile includes a pre-embedded section and a connecting section. The pre-embedded section has helical blades on its outer side, and the connecting section has an insertion hole inside and a second flange on its top. The first flange and the second flange have corresponding connection holes. The end of the support column is inserted into the insertion hole and connected by a second bolt. A concrete pouring layer is provided outside the connecting section. This photovoltaic support ground connection structure has the advantages of simple and convenient construction, high connection reliability, and long service life.

[0006] As a further improvement of this utility model, the first connecting bolt includes two bolts, one upper and one lower, and the second bolt is one bolt. A reinforcing plate is provided on the connecting section corresponding to the position where the second bolt passes through, so as to ensure the reliability of the connection and the structural strength of the connection position.

[0007] As a further improvement of this utility model, a tightening screw is provided around the upper end of the connecting section, with the tail of the tightening screw abutting against the outer wall of the support column. This ensures the verticality of the support column, thereby ensuring the stability of the tilt angle of the photovoltaic panel mounting frame.

[0008] As a further improvement of this utility model, the thickness of the concrete pouring layer is not less than 200mm, which further ensures the reliability of the connection.

[0009] As a further improvement of this utility model, the support column has a rectangular cross-section, which is convenient to manufacture and has high structural strength; the helical pile has a circular cross-section, which is convenient for construction.

[0010] As a further improvement of this utility model, reinforcing ribs are intersecting between the front columns and between the rear columns in the middle section, which further improves the structural stability of the entire photovoltaic support. Attached Figure Description

The photovoltaic panel mounting frame 2 is an existing technology structure, including inclined beams and purlins, on which the photovoltaic panels are mounted. The support column 1 includes a front column and a rear column, with the front column being lower than the rear column to allow the photovoltaic panels to be installed at an angle, thus improving power generation efficiency.
