Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, and specifically designs a photovoltaic guide rail heightening base. Background Art

[0002] The photovoltaic rail heightening base plays a certain role in the rail installation of the photovoltaic system. It can provide additional height for the rail to adapt to different installation environments and component requirements. For example, they can be used to adjust the distance between the photovoltaic panels and the ground to meet the needs of cleaning and maintenance, or to ensure that the components will not be affected by snow or water accumulation; the photovoltaic rail heightening base can prevent the rail from direct contact with the ground, thereby achieving a heat insulation effect and reducing the impact of ground temperature on the performance of photovoltaic modules; it can make the installation of the rail more flexible.

[0003] However, the existing photovoltaic rail heightening bases usually use rubber pads. The rubber material will age over time, especially under ultraviolet radiation and extreme temperatures. The rubber pads may become hard, brittle, or even cracked; even regular maintenance and replacement will increase the corresponding costs. Utility Model Content

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0028] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Reference Figure 1-3 As shown, a photovoltaic rail heightening base includes a bottom plate 1 and side plates 2, wherein the side plates 2 are symmetrically arranged on both sides of the bottom plate 1, and the bottom plate 1 and the side plates 2 are integrally formed by bending a flat plate material, and the integrally formed structure has high strength and is easy to process.

[0030] At least one boss 11 is provided at the center of the upper surface of the bottom plate 1, and multiple bosses can be provided as needed to increase the supporting force. The boss 11 is formed by stamping the bottom plate 1 with a mold. The upper end surface of the boss 11 is parallel to the bottom surface, and the upper end surface of the boss 11 contacts the bottom surface of the guide rail to provide vertical supporting force for the guide rail 4. A bent portion 22 protruding toward the boss 11 is provided on the side plate 2, and a clamping force is applied to both sides of the guide rail 4 to fix the photovoltaic guide rail heightening base and the guide rail. The bottom plate 1 can be placed on the mounting plane of the guide rail, or a rubber pad 3 can be provided on the lower end surface of the bottom plate 1, which can increase the friction between the photovoltaic guide rail heightening base and the mounting plane to prevent the photovoltaic guide rail heightening base from sliding. The volume of the rubber pad 3 is not large, and is smaller than the existing rubber pad 3 used as a heightening base. Even if the rubber pad 3 is damaged after a long time, it will not have a significant adverse effect on the overall effect of the photovoltaic guide rail heightening base.

[0031] The side plate 2 further includes a vertical section 21. The bent portion 22 includes a first bent section 221 and a second bent section 222. The vertical section 21 is vertically connected to the bottom plate 1. The first bent section 221 bends towards the side close to the boss 11 and forms an angle R1 with the vertical section 21. The second bent section 222 bends towards the side away from the boss 11 and forms an angle R2 with the first bent section 221. When the angle between the first bent section 221 and the horizontal plane is less than the angle between the hypotenuse at the bottom of the guide rail and the horizontal plane, when the guide rail 4 is installed on the photovoltaic guide rail heightening base, the first bent section 221 abuts against the hypotenuse at the bottom of the guide rail 4, and the side plate 2 undergoes elastic deformation towards the outside, making the connection between the guide rail and the photovoltaic guide rail heightening base more stable.

[0032] The boss 11 includes a horizontal portion 111 and inclined portions 112 symmetrically arranged at both ends of the horizontal portion 111. The inclined portions 112 form an angle R3 with the bottom plate 1, and 30° ≤ R3 ≤ 60°. This can make the boss 11 form more stably, reduce the possibility of material tearing, the height of the boss 11 can also meet certain requirements, and moreover, the downward pressure of the guide rail 4 is more evenly distributed, making the load-bearing stability of the boss 11 better.

[0033] The angle R1 between the first bent section 221 and the vertical section 21 is less than the angle R2 between the second bent section 222 and the first bent section 221. The second bent section is located at the open section of the photovoltaic guide rail heightening base. R1 < R2 can make the guide rail 4 easier to install.

[0034] A fillet transition is provided at the connection between the first bent section 221 and the second bent section 222 for the guide rail 4 to be snapped in. As Figure 4 shown, when the guide rail is snapped into the photovoltaic guide rail heightening base, one side is first inserted to abut against the first bent section 221, and the other section only needs to be gently pressed in, and the installation is completed.

[0035] The bottom plate 1 and the side plate 2 are made of one of the following materials: stainless steel, aluminum alloy or galvanized aluminum magnesium. In this embodiment, galvanized aluminum magnesium material is preferably used, which has good anti-corrosion performance and damage resistance, and is lighter and more convenient in quality.

[0036] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
