Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, and more specifically, relates to an integrated photovoltaic structure built into fair-faced concrete. Background Technology

[0002] Photovoltaic power generation is a clean energy technology that uses the photovoltaic effect of semiconductor materials to directly convert solar energy into electrical energy. It has the characteristics of safety, renewability, and zero pollution. Its core forms include distributed generation and building-integrated photovoltaics (BIPV), the latter of which integrates power generation with building functions through photovoltaic roof tiles, curtain walls, etc. Its technological advantages lie in the fact that it does not require fuel and is flexible in installation.

[0003] For example, patent application number CN202120081011.2 discloses a photovoltaic integrated precast concrete support foundation system, including a base platform one and a base platform two. The base platform one is a concrete structure, and an annular groove is formed on the periphery of the base platform one. Several support brackets are placed on the upper end of the groove. The upper end of the support brackets is the same as that of the base platform two. The structure of the base platform two and the base platform one is the same. The base platform one and the base platform two are arranged opposite to each other. A frustum is set in front of the base platform one and the base platform two. A photovoltaic panel is installed on the upper end of the base platform two. A connecting pipe two is arranged through the center of the base platform one and the frustum. Several connecting pipes one are arranged in the groove of the base platform one. This application can be freely stacked and raised to adapt to different environments.

[0004] Based on the above, the photovoltaic equipment currently in use still has the following problems: 1. The lack of a proper installation and positioning structure generally results in a poor connection between the photovoltaic module and the exposed concrete, affecting both installation efficiency and accuracy. 2. When the photovoltaic module is not installed in place, it cannot move automatically, making it difficult for staff to know the effect of the photovoltaic module after installation; 3. Photovoltaic modules are usually installed with bolts, which is not conducive to the installation and disassembly of photovoltaic modules, and to subsequent maintenance and replacement of photovoltaic modules.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, four rectangular positioning strips are fixedly installed on the mounting base, and the outer ends of the four rectangular positioning strips are rounded. The outer ends of the four rectangular positioning strips are in contact with the fair-faced concrete body, which plays a positioning role in the installation position of the mounting base, making the installation position of the mounting base more accurate. Furthermore, because the circular connector is inserted into the interior of the mounting base, and the photovoltaic support frame is fixedly installed on the front side of the circular connector, and the outer wall of the photovoltaic support frame is in contact with the fair-faced concrete body, it is convenient for the photovoltaic support frame to connect with the fair-faced concrete body, so that the photovoltaic support frame can be installed exactly inside the fair-faced concrete body.

[0017] 2. In this invention, two positioning anti-detachment brackets are fixedly installed on the mounting base, and two positioning anti-detachment pins are slidably installed on the two positioning anti-detachment brackets and the mounting base.

Furthermore, two limiting rings a are fixedly installed on the outside of the positioning anti-detachment pins, and two support springs b are sleeved on the outside of the two positioning anti-detachment pins. The two support springs b are located between the two positioning anti-detachment brackets and the two limiting rings a, which provides elastic support for the two positioning anti-detachment pins. This ensures that the two positioning anti-detachment pins will only move when subjected to tension, preventing the positioning anti-detachment pins from falling off the inclined positioning grooves. In addition, because the support spring a is installed inside the circular connector, and the front end of the support spring a is fixedly connected to the photovoltaic support frame, and the rear end of the support spring a is in contact with the mounting base, when the circular connector is not inserted in place, the support spring a can push the photovoltaic support frame forward, making it easy for staff to know the installation status of the photovoltaic support frame.

In this invention, because two U-shaped handles are slidably mounted on the photovoltaic support frame, and two limiting clamping plates are fixedly mounted on the outside of the two U-shaped handles, and the rear sides of the two limiting clamping plates are in contact with the photovoltaic support frame, they provide a limiting and clamping effect on the photovoltaic module body, ensuring that the photovoltaic module body is in a stable state after being connected to the photovoltaic support frame; and because four limiting rings b are fixedly mounted on the inner ends of the two U-shaped handles, and four support springs c are sleeved on the outside of the two U-shaped handles, and the four support springs c are located between the photovoltaic support frame and the four limiting rings b, they provide an elastic support effect on the two U-shaped handles, ensuring that the two U-shaped handles will only move when subjected to tension, thus guaranteeing that the two limiting clamping plates are always in contact with the photovoltaic module body.
