Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic, and particularly relates to a vertical photovoltaic bracket and its components. Background Art

[0002] With the increasing shortage of traditional fossil energy, the development and application of renewable energy have attracted more and more attention. As an important renewable energy, solar photovoltaic power generation has broad prospects.

[0003] Photovoltaic glass, also known as "photoelectric glass", is a special glass that is used in combination with solar photovoltaic modules, can generate electricity using solar radiation, and has relevant current lead-out devices and cables. It is mainly composed of glass, solar cells, film, back glass, special metal wires, etc. Photovoltaic glass is a new type of high-tech glass product for buildings, and can be applied to solar intelligent windows, solar pavilions, photovoltaic glass building roofs, photovoltaic glass curtain walls, etc. Its performance and output are affected by factors such as inclination angle, orientation, and shadow occlusion. In high-altitude areas such as plateaus, the sunshine time is long, the atmosphere is thin, the air is clean, the solar radiation is strong, and the temperature difference between day and night is large. There are rich solar energy resources and good conditions for using photovoltaic power generation.

[0004] However, when installing solar photovoltaic modules in plateau areas, the photovoltaic brackets are usually arranged in the plateau area and fixed to the ground. Then, the photovoltaic glass is laid flat on the photovoltaic brackets, and the orientation angle of the photovoltaic glass is adjusted to make the time of direct sunlight the longest. Multiple photovoltaic glasses are usually installed together in a planar series connection method, which occupies a large space and requires a large area for laying photovoltaic modules. However, for plateaus with more mountainous terrains, the flat laying method is tantamount to reducing the installation amount of photovoltaic modules, resulting in waste of light energy. Content of the Utility Model

[0005] The utility model aims to provide a vertical photovoltaic bracket and its components to solve the problem that the existing method of installing photovoltaic modules greatly reduces the installation amount of photovoltaic modules, resulting in waste of light energy in plateau areas.

[0006] A vertical photovoltaic bracket and its components in this solution include a bracket assembly and multiple photovoltaic panel groups. The bracket assembly includes a central tower pole and a base. The base is fixedly connected to one end of the central tower pole. The central tower pole is fixedly connected with multiple fixing frames, and the multiple fixing frames are arranged around the central tower pole at different horizontal planes. The photovoltaic panel groups are detachably connected to the peripheries of two adjacent fixing frames.

[0007] Working principle and beneficial effects of this solution: A central tower pole and a fixing frame surrounding the central tower pole are provided. The photovoltaic panel group can be vertically installed between two adjacent fixing frames. During installation, the base of the central tower pole is fixed to the ground at the installation site, and then the photovoltaic panel group is fixed perpendicular to the ground between two adjacent fixing frames. Multiple photovoltaic panel groups can be arranged in a circle around the fixing frame, and multiple layers of photovoltaic panel groups can be arranged between multiple fixing frames, effectively reducing the floor area of the photovoltaic panel group. It enables more photovoltaic panel groups to be installed in a limited terrain environment, greatly increasing the power generation area of the photovoltaic modules and effectively improving the total power generation. The surrounding photovoltaic panel groups can receive sunlight at different angles, avoiding the problem of light energy waste caused by irradiation dead angles.

[0008] Furthermore, the central tower pole is a regular polygon, and the fixing frame is composed of multiple triangular support frames. Each support frame consists of a positioning rod, a connecting rod, and two triangular support rods. One end of each of the two triangular support rods is fixedly connected to the same point on the central tower pole, and the other ends of the two triangular support rods away from the central tower pole are respectively fixedly connected to both ends of the positioning rod. One end of the connecting rod is fixedly connected to the intersection point of the two triangular support rods, and the other end of the connecting rod is fixedly connected to the middle of the positioning rod. Multiple support frames surround the central tower pole to form a regular polygon with the same number of sides as the central tower pole. The regular polygon central tower pole facilitates the fixed connection with the fixing frame, and the regular polygon fixing frame can increase the contact positions between the edge of the fixing frame and the photovoltaic panel group, increasing the number of fixing points of the photovoltaic panel group and making the installation more stable.

[0009] Furthermore, a flange is fixedly connected to the end of the central tower pole away from the base. The presence of the flange enables the central tower pole to be connected to other central tower poles, extending the installation layers of the photovoltaic panel group, or used to increase the height of the overall photovoltaic panel group to improve the ability of the photovoltaic panel group to receive sunlight and prevent animals on the ground from damaging the photovoltaic panel group.

[0010] Furthermore, a support frame is provided above a part of the fixing frames. The support frames are spaced apart relative to the fixing frames. The support frame includes an inclined rod, a support rod, and two support inclined rods. One end of the inclined rod is fixedly connected to the middle of the positioning rod, and the other end of the inclined rod is located above the intersection of the two triangular support rods and is fixedly connected to the central tower rod. The positions where the triangular support rods and the inclined rod are fixedly connected to the central tower rod are on the same vertical line. One ends of the two support inclined rods are fixedly connected to the fixing position of the inclined rod and the central tower rod, and the other ends of the two support inclined rods are respectively fixedly connected to the two ends of the positioning rod. One end of the support rod is fixedly connected to the middle of the inclined rod, and the other end is fixedly connected to the intersection of the two triangular support rods. The inclined rod and the support inclined rods of the support frame form a triangle with the positioning rod and the connecting rod of the fixing frame. Since a triangle has the strongest stability in a plane, the support frame can better support the fixing frame. The spaced-apart support frames can better support one of the fixing frames when installing the photovoltaic panel group, making the installation of the photovoltaic panel group more stable.

[0011] Furthermore, the photovoltaic panel group includes a cover plate, photovoltaic glass, and a bottom plate. The cover plate and the bottom plate fix the photovoltaic glass in the middle, one above the other. A plurality of mounting holes are provided on the periphery of the cover plate, and a plurality of threaded holes are provided at positions corresponding to the mounting holes on the bottom plate. The cover plate and the bottom plate are detachably connected by fasteners. After installing the photovoltaic glass between the cover plate and the bottom plate, screws are used to fix the cover plate and the bottom plate together through the mounting holes and the threaded holes. The cover plate and the bottom plate can effectively protect the periphery of the photovoltaic glass from being broken by impact and provide a mounting position for the photovoltaic glass.

[0012] Furthermore, the bottom plate includes an outer frame and an inner frame. The outer frame is a rectangular frame with the same size as the cover plate. The inner frame is provided with a plurality of cross bars and a plurality of vertical bars. The plurality of cross bars and vertical bars are all perpendicular to each other to form a grid shape and are fixedly connected to each other. The inner frame is fixedly connected to the outer frame. The side of the inner frame close to the photovoltaic glass is slightly lower than the outer frame, and the height difference is the thickness of the photovoltaic glass. The photovoltaic glass is installed on the upper surface of the inner frame, and the outer frame wraps the photovoltaic glass. The inner frame formed by the fixedly connected plurality of cross bars and vertical bars can effectively increase the contact area between the photovoltaic glass and the bottom plate, improve the flatness of the bottom plate, avoid torsion of the photovoltaic glass during installation and damage to the glass, and the outer frame surrounds all four sides of the photovoltaic glass. When used in cooperation with the cover plate, it can effectively limit the movement space of the photovoltaic glass and avoid shaking of the photovoltaic glass.

[0013] Furthermore, a sealing strip made of rubber is provided at the position where the cover plate contacts the photovoltaic glass, and a buffer pad made of rubber is provided at the position where the inner frame contacts the photovoltaic glass. The rubber sealing strip and buffer pad play a buffering role for the photovoltaic glass, avoiding the situation where the photovoltaic glass collides with the cover plate and the bottom plate and causes damage to the photovoltaic glass.

[0014] Furthermore, a plurality of mounting buckles are fixedly connected to the edge of the bottom plate. The mounting buckles facilitate the installation of the photovoltaic panel group and the fixing frame. BRIEF DESCRIPTION OF THE DRAWINGS
