Description

A new type of agricultural photovoltaic greenhouse

technical field

The utility model belongs to the technical field of agricultural photovoltaic greenhouse planting, in particular to a novel agricultural photovoltaic greenhouse.

Background technique

The application of solar greenhouses has greatly improved the heating method of greenhouse cultivation. Its advantage is that the use of solar energy to heat the greenhouse replaces the traditional boiler combustion heating method, which not only conforms to the green and low-carbon development form, but also reduces the economic cost of greenhouse planting from the perspective of long-term development. Therefore, solar greenhouses have been widely promoted.

Solar photovoltaic greenhouses provide thermal energy for greenhouses through solar photovoltaic panels collecting light and heat. Solar photovoltaic panels require a certain layout space and need to be arranged in places that can receive sunlight. In the application of the prior art, the common way is to place the solar photovoltaic panel on the top of the greenhouse, or place it separately on the light-receiving field outside the greenhouse. Of these two arrangements, the former affects the plant lighting effect of the greenhouse itself, and the latter increases the land use area.

The main resources in agricultural production are land resources, and the rational use of land planting area directly affects the economic benefits of agricultural production. Without affecting the planting land area and the lighting of greenhouse plants, how to reasonably solve the lighting arrangement of photovoltaic panels in agricultural photovoltaic greenhouses is of great practical significance to improve the economic effect of agricultural production.

The new agricultural photovoltaic greenhouse described in the utility model includes a planting sun shed, a planting shade shed and a photovoltaic panel assembly. The component support is the frame of the planting awning; the planting awning is arranged on the sunny side, and the planting awning is arranged on the back side; the front column of the photovoltaic module support is placed on the rear top of the planting awning, and the rear column is placed on the ground; the planting awning The shed is built with an arc-shaped roof support frame from the front wall to the top of the back wall. From the ridge of the roof, it is divided into a front roof and a back roof. The backside of the roof of the awning is connected with the planting shade as a drainage ditch; the rear wall panel of the planting shade is installed on the rear column of the photovoltaic module bracket.

The rear wall of the planting awning is a thermal insulation wall.

The inclination angle of the photovoltaic panel assembly is adjusted according to the range of solar incidence angles in different regions.

The photovoltaic panel assembly is connected to the power storage device inside the temperature control room of the greenhouse.

The beneficial effect of the utility model is that: the land space for greenhouse planting is rationally planned, arranged and utilized, and the utilization rate of the land is maximized under the condition that the photovoltaic power generation is not affected, so as to create as many agricultural economic benefits as possible.
