Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation mechanism. Background Art

[0002] Photovoltaic power generation refers to a power generation method that uses solar photovoltaic cells to directly convert solar radiation energy into electrical energy. It is also a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels, controllers and inverters. The mechanism that uses these components to generate electricity is a photovoltaic power generation mechanism. Photovoltaic power generation is the mainstream of solar power generation today. Photovoltaic power generation mechanisms make full use of local solar energy resources to replace and reduce fossil energy consumption. The controllers of common photovoltaic power generation mechanisms on the market need to be protected by protective structures to reduce aging. However, the protective structure will affect the heat dissipation efficiency of the controller and its service life. In addition, when photovoltaic power generation mechanisms are installed in plateau terrain for use, they are prone to strong winds. Strong winds can cause damage to the structural parts of the photovoltaic power generation mechanism. When the photovoltaic panels of the photovoltaic power generation mechanism are damaged or cleaned, they need to be disassembled and removed, which is cumbersome. Summary of the invention

[0003] The disclosed embodiment of the present invention relates to a photovoltaic power generation mechanism, whose force-bearing parts can be cast inside concrete, so that when the power generation mechanism, the flip frame structure and the photovoltaic panel encounter strong winds, the wind will transmit force to the bracket, causing the bracket to move. When the bracket is displaced by the strong wind, the bottom component drives the top plate and the control rod to move, compressing the spring outside the control rod to eliminate the impact force generated by the strong wind, eliminate stress, and avoid damage to the entire power generation mechanism. Even if the bracket and the bottom component produce lateral displacement, the sliding rod assembly can slide laterally inside the slide groove to eliminate the lateral force, thereby effectively protecting the power generation mechanism and the photovoltaic panel.

[0006] In at least some embodiments, a stop block is provided above the end of the bottom component, a slide groove is provided on both sides of the end of the bottom component, a groove is provided at the bottom of the bottom component, and a freely rotatable rotating part is installed inside the groove through a rotating shaft; a sliding rod assembly with an L-shaped structure is inserted into the interior of the slide groove, and four sliding rod assemblies are symmetrically welded on both sides of the top plate, and the bottom of the top plate is in sliding contact with the top of the bottom component; a pressure rod assembly is inserted through the interior of the two force-bearing head assemblies on the same side, and a retaining ring is provided on the outside of the pressure rod assembly, which fits the side of the force-bearing head assembly, and the bottom of the pressure rod assembly is fixedly connected to the force-bearing member through a square plate, and the force-bearing member is cast inside the concrete.

[0007] In at least some embodiments, a connector is installed at the bottom of the flip frame structure through a rotating shaft, and the connector is mounted on the outside of the driving rod. After the driving rod rotates, the connector is controlled to move through a thread, and the connector pulls the flip frame structure to flip. A top rod structure is welded at the upper and lower ends of the flip frame structure respectively; the top rod structure at the bottom is welded and fixed to two L-shaped limit blocks, and a positioning rod structure is welded at the top of the kit.

[0008] The present invention provides a photovoltaic power generation mechanism, which has the following beneficial effects:

[0009] 1. During the use of the power generation mechanism, the light source tracking sensor can identify the position of the sun in real time, and then transmit the signal to the controller. The controller controls the servo motor to operate, and then drives the drive rod to operate.

[0011] 3. The load-bearing parts can be cast inside the concrete, so that when the power generation mechanism, the flip frame structure and the photovoltaic panel encounter strong winds, the wind will transfer the force to the bracket, causing the bracket to move. When the bracket is displaced by the strong wind, the bottom assembly drives the top plate and the control rod to move, compressing the spring outside the control rod to eliminate the impact force generated by the strong wind, eliminate stress, and avoid damage to the overall power generation mechanism. Even if the bracket and the bottom assembly produce lateral displacement, the sliding rod assembly can slide laterally inside the slide groove to eliminate the lateral force and effectively protect the power generation mechanism and the photovoltaic panel.

[0012] 4. If you need to replace the photovoltaic panel, you can directly push the photovoltaic panel up to move the photovoltaic panel push kit upward, compress the spring, and at the same time, the rod will be disengaged from the inside of the limit block to control the bottom of the photovoltaic panel to move upward, so that the photovoltaic panel can be easily released and replaced or removed.

When encountering strong winds, after the device as a whole is subjected to the force generated by the strong wind, the bottom component 2 drives the top plate 204 and the control rod 205 to move, compressing the spring outside the control rod 205 to eliminate the impact force and stress generated by the strong wind. Even if the bracket 106 and the bottom component 2 produce lateral displacement, the sliding rod component 203 slides laterally inside the slide groove 201 to eliminate the lateral force, avoid damage to the power generation mechanism 1 as a whole, and effectively protect the power generation mechanism 1 and the photovoltaic panel 307.
