Description
Technical Field
[0001] This utility model relates to an agricultural greenhouse, specifically a photovoltaic agricultural greenhouse with adjustable light transmittance. Background Technology
[0002] Photovoltaic agricultural greenhouses are a new type of agricultural facility that combines solar power generation with agricultural production. They generate solar power by installing photovoltaic systems on the roof of the greenhouse, while the interior space can be used for crop cultivation, forming a three-dimensional production model of "power generation on the roof, cultivation inside."
[0003] Existing photovoltaic agricultural greenhouses have complex structures and unreasonable designs. Due to the shading of the photovoltaic equipment, the amount of light entering the greenhouse is greatly reduced. Furthermore, the greenhouses typically use a thin film as the main structure, resulting in very low light transmittance, which seriously affects the photosynthesis of crops inside. In addition, the photovoltaic equipment on the greenhouse is very heavy, putting significant stress on the greenhouse's frame structure. Over time, this can lead to decreased stability and damage to the frame structure in windy conditions, shortening its lifespan. Therefore, the inventors have improved the structure of photovoltaic agricultural greenhouses. Utility Model Content
[0004] The purpose of this invention is to provide a photovoltaic agricultural greenhouse with adjustable light transmittance. This photovoltaic agricultural greenhouse has a simple structure and reasonable design. Through the vertically placed main body and the inclined secondary body, the two work together to adjust the light transmittance according to the different angles and intensities of sunlight throughout the day. Since both the secondary and main covering panels are made of PC boards, they can provide sufficient light for the crops inside the greenhouse, which is conducive to better promoting photosynthesis. They can also effectively withstand the pressure of the photovoltaic structure and effectively resist impact in windy environments, thus solving the problems mentioned in the above-mentioned technical background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic agricultural greenhouse with adjustable light transmittance, comprising a support mechanism and a photovoltaic mechanism inclinedly arranged on the support mechanism. Multiple sets of frame mechanisms are spaced apart between the support mechanism and the photovoltaic mechanism. Each set of frame mechanisms includes multiple support rods and load-bearing components arranged on the multiple support rods. Each support rod is provided with a slot, and a wind-resistant component is provided between the support rod and the load-bearing component. The load-bearing component includes a central rod and multiple connecting pieces fixed to the central rod. The multiple connecting pieces surround the outside of the central rod. The wind-resistant component includes a flat frame and multiple pressure-distributing rods fixed to the flat frame. The flat frame is inserted into multiple slots and fixed to the multiple support rods.
[0006] Preferably, the support mechanism includes a U-shaped base frame, with secondary cover plates fixed at both ends of the base frame, door curtains installed on both secondary cover plates, and two sets of main cover plates installed between the two secondary cover plates.

Adjacent main plates are fixedly connected. Each main plate has a tilted sub-plate fixed on it. The sub-plates of the two sets of main cover plates are fixed together at their closest points to each other to ensure the overall stability of the main cover plates.
[0008] Preferably, the photovoltaic mechanism includes two sets of photovoltaic panels arranged opposite each other, each set of photovoltaic panels has multiple panels spaced apart, and adjacent photovoltaic panels are connected by a fixing frame. Multiple fixing frames are provided, and the multiple fixing frames are respectively fixed on the two sets of sub-panels.
[0009] Preferably, the center rod includes a main rod body and a fixing part fixed to the main rod body. A cross-shaped insertion hole is provided at the end of the main rod body away from the fixing part. The flat plate frame is inserted into the insertion hole. The center rod is set at the center position of the flat plate frame, so that the center rod and the flat plate frame can be combined into one piece. The center rod is locked to the flat plate frame by several bolts.
[0010] Preferably, four connecting pieces are provided, and the ends of the four connecting pieces away from the flat plate frame are respectively fixed to the four corners of the flat plate frame.
[0011] Preferably, the flat plate frame is in the shape of a grid, and four positioning holes are provided through the flat plate frame. A total of four pressure dividing rods are provided, and the upper end face of each of the four pressure dividing rods is fixed with a stake. The four stakes are inserted into the four positioning holes from the outside to the inside.
[0012] Preferably, multiple pressure-dividing rods are inclined, and the inclination angle of the multiple pressure-dividing rods is between 12° and 28°. The use of inclined pressure-dividing rods can effectively support the overall structure of the load-bearing component and ensure that the load-bearing component remains structurally stable above the wind-resistant component.
