Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a greenhouse with vertical photovoltaic modules. Background Technology

[0002] Photovoltaic modules (also called solar panels) are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then stored in batteries or used to power loads.

[0003] A photovoltaic (PV) vegetable greenhouse is simply a regular vegetable greenhouse with solar panels installed on its roof. It utilizes solar energy, dividing solar radiation into light energy needed for plant growth and light energy for power generation. This satisfies the plant's needs while simultaneously achieving photoelectric conversion. A PV vegetable greenhouse can both generate electricity and grow vegetables, serving a dual purpose.

[0004] The construction of photovoltaic vegetable greenhouses has increased renewable energy, enabling agriculture to move towards low-carbon, high-efficiency, green, and circular agriculture. Compared with ordinary vegetable greenhouses, photovoltaic vegetable greenhouses have advantages such as heat preservation, reduced pests and diseases, resistance to severe weather such as hail, radiation, rainstorms, and strong winds, and no pollution.

[0005] In east-west or north-south oriented greenhouses, there is a lack of photovoltaic modules that can simultaneously meet the needs of plants and electricity. The steel structure frame of the greenhouse is generally covered with a flat, light-transmitting film, which cannot efficiently utilize the energy released by sunlight. There is a lack of greenhouses with high-efficiency vertical photovoltaic modules. Utility Model Content

[0006] Therefore, this utility model provides a greenhouse with vertical photovoltaic modules to solve the above-mentioned problems in the prior art. To achieve the above objective, this utility model provides the following technical solution: According to a first aspect of this utility model, a greenhouse with vertical photovoltaic modules includes an arc-shaped greenhouse body, a supporting structure, and photovoltaic modules connected to the supporting structure and fixed vertically to the ground; the top of the arc-shaped greenhouse body is fixedly supported by the photovoltaic modules, and the other side is fixed to the ground; the arc-shaped greenhouse body is composed of an arc-shaped steel structure frame covered with a light-transmitting and refractive greenhouse film, and the lower surface of the light-transmitting and refractive greenhouse film is a sawtooth refractive mirror surface, i.e., a Fresnel mirror surface.

[0007] Furthermore, the refractive surface angle of the mirror surface is any angle between 20° and 60°, and the refractive surface is either a plane or a curved surface.

[0008] Furthermore, when the supporting structure is a pillar set on the ground, the photovoltaic module is fixed to the top of the pillar; when the lightweight photovoltaic module is suspended under the top of the arc-shaped canopy, the top of the photovoltaic module is connected to the top of the arc-shaped steel structure frame, and the photovoltaic module is perpendicular to the ground in the suspended state; the photovoltaic module is a double-sided photovoltaic module, with both sides of the photovoltaic module facing the arc-shaped canopy.

[0009] Furthermore, when the supporting structure is a wall set on the ground, the photovoltaic modules are attached to the side of the wall. The photovoltaic modules are single-sided photovoltaic modules, and the side of the photovoltaic module that receives sunlight and generates electricity faces the curved canopy.

[0010] Furthermore, within the arched canopy, a reflective film is installed by connecting the arched steel frame to the photovoltaic modules.

[0011] Furthermore, when the reflective film is installed, the top of the photovoltaic module is rotatably connected to a lifting shaft, which is connected to an adjustable roller at its lower part by a traction rope. One side of the reflective film is wound on the adjustable roller; the inner side of the arc-shaped steel structure frame is fixedly connected to a fixed roller (6), and the other two sides of the reflective film are fixedly connected by the fixed roller.

[0012] Furthermore, the reflective film has holes, which allow some sunlight to pass through and reach the ground. The unperforated portion of the reflective film reflects sunlight that is not needed by the plants on the ground onto the photovoltaic modules to generate electricity.

[0013] Furthermore, the lifting axis is manually adjustable.

[0014] Furthermore, the lifting shaft is used for motor rotation adjustment.

[0015] Furthermore, the supporting structure is perpendicular to the ground.

[0016] The present invention has the following advantages: Through the greenhouse with vertical photovoltaic modules of the present invention, the plants grow better, the sunlight utilization rate is higher, the power generation efficiency of the photovoltaic modules is significantly improved, and the power generation output of the photovoltaic modules is greater in the early morning and late afternoon.

[0025] The technical effects achieved by the above embodiments are as follows: through the greenhouse with vertical photovoltaic modules in this embodiment, the plants grow better, the sunlight utilization rate is higher, the power generation efficiency of the photovoltaic modules is significantly improved, and the power generation output of the photovoltaic modules is greater in the early morning and late afternoon.

[0026] Example 2

[0027] like Figures 1 to 4 As shown, a greenhouse with vertical photovoltaic modules includes all the contents of Example 1, except that the refractive angle of the refractive mirror surface 3-3 is any angle between 20° and 60°, and the refractive surface is a plane or an arc surface.

[0028] The technical effect achieved by the above embodiments is that the refractive efficiency of the light-transmitting and refractive membrane 3 is significantly improved.

[0029] Example 3

[0030] like Figures 1 to 2 As shown, a greenhouse with vertical photovoltaic modules includes all the contents of Embodiment 2. In addition, when the support structure 2 is a pillar set on the ground, the photovoltaic module 1 is fixed to the top of the pillar; when the lightweight photovoltaic module 1 is suspended under the top of the arc-shaped greenhouse 3, the top of the photovoltaic module 1 is connected to the top of the greenhouse of the arc-shaped steel frame 3-1, and the photovoltaic module 1 is perpendicular to the ground in the suspended state; the photovoltaic module 1 is a double-sided photovoltaic module, and both sides of the photovoltaic module 1 face the arc-shaped greenhouse 3.

[0031] It should be noted that the lightweight bifacial photovoltaic modules without frames or glass are suspended in the center of the greenhouse, or the bifacial photovoltaic modules are supported by pillars in the center. This solution is suitable for installing vertical photovoltaics in east-west or north-south oriented greenhouses.

[0032] Example 4

[0033] like Figures 3 to 4 As shown, a greenhouse with vertical photovoltaic modules includes all the contents of Embodiment 2. In addition, when the supporting structure 2 is a wall set on the ground, the photovoltaic module 1 is attached to the side of the wall. The photovoltaic module 1 is a single-sided photovoltaic module, and one side of the photovoltaic module 1 faces the curved greenhouse 3.

[0034] It should be noted that this solution involves attaching frameless single-glass or glassless photovoltaic modules to the north wall. This solution is applicable to the installation of vertical photovoltaic systems on the north wall of a south-facing greenhouse.

[0035] Example 5

[0036] like Figure 2 and Figure 4 As shown, a greenhouse with vertical photovoltaic modules includes all the contents of embodiment 3 or 4.

The unperforated portion of the reflective film 4 reflects sunlight that is not needed by the plants on the ground onto the photovoltaic module 1 to generate electricity. Specifically, the reflective film 4 can be totally reflective and used when no plants are grown in the greenhouse. Alternatively, the reflective film 4 can be perforated at a required ratio to allow some light to pass through and meet the sunlight needs of the plants grown in the greenhouse. Or, the reflective film 4 can be without a reflective film 4.

[0039] Optionally, the lifting shaft 5 can be adjusted manually or by motor rotation.
