Description

Technical Field

[0001] The utility model relates to the technical field of agriculture-photovoltaic integrated greenhouses, in particular to an economical agriculture-photovoltaic integrated plant factory. Background Art

[0002] Integrated agriculture and photovoltaic (AP) greenhouses combine photovoltaic (PV) projects with simple plant factories, enabling shared facilities, space, and management. This reduces the investment and operational costs of simple plant factories, including the cost of building the plant factory (or facility greenhouse) framework, ongoing operations and maintenance, and electricity costs. It also improves the utilization of under-panel space and land in PV projects. Modern facility greenhouses represent the primary upfront cost of integrated agriculture and photovoltaic (AP) greenhouses. However, existing integrated agriculture and photovoltaic (AP) greenhouses also require PV module maintenance. This requires removing the plastic film covering the roof, and the modules are typically 3-4 meters above the ground, requiring operators to operate from mid-air. This increases the operational complexity, making existing integrated agriculture and photovoltaic (AP) greenhouses difficult to maintain. Utility Model Content

[0040] The photovoltaic modules of the photovoltaic support 100 and the film layer 1 between the photovoltaic support 100 form the roof of the integrated agricultural and photovoltaic greenhouse. This structure saves the film layer structure below the photovoltaic support 100 and can reduce the construction cost by more than 30%. It further improves the efficiency and success rate of industrialized vegetable production using the integrated agricultural and photovoltaic greenhouse. Figures 1-3 In the integrated agricultural and photovoltaic greenhouse, the bottom of the photovoltaic module is open to facilitate the inspection and maintenance of the photovoltaic module.

[0041] The preferred solution is Figures 1-3 In the example, the frames of adjacent photovoltaic racks 100 are connected by connecting rods 8. One end of the connecting rod 8 is connected to the high point of the frame of the preceding photovoltaic rack 100, and the other end is connected to the low point of the frame of the adjacent photovoltaic rack 100. Multiple connecting rods 8 are arranged along the length of a row of photovoltaic racks 100. The film layer 1 is disposed on and fixedly connected to the connecting rods 8. This structure provides support for the film layer 1, reducing the strength requirements of the film layer 1.

[0042] The preferred solution is Figure 2 In the embodiment, the end of the connecting rod 8 is fixedly connected to the frame beam 5 of the photovoltaic support 100 by the first screw 10. This structure simplifies the connection structure. During installation, holes are drilled at corresponding positions of the frame beam 5, and then the connecting rod 8 is fixedly connected to the frame beam 5 with self-tapping screws.

[0043] The preferred solution is Figure 3 、 Figure 11 In the embodiment, a water collecting trough 13 is provided on the connecting rod 8; this structure simplifies the installation structure of the water collecting trough and facilitates installation.

[0044] The water collection tank 13 is arranged along the length of a row of photovoltaic brackets 100, and the connecting rod 8 passes through the edge of the water collection tank 13. The water collection tank 13 is located at the lower end of the connecting rod 8. The structure of the water collection tank 13 can quickly drain the water therein to avoid burdening the photovoltaic bracket.

[0045] The preferred solution is Figure 4 In the embodiment, the side walls 7 are made of plastic film and connected to rods. The connecting plate 3 is provided with side wall connecting clips 31. The side walls 7 are connected to the side wall connecting clips 31 via the rods, and the connecting plate 3 is fixedly connected to the frame crossbeam 5.

The inner space height of the slot 32 is slightly smaller than the height of the slot elastic member 33, so that the slot elastic member 33 is always in a deformed state and is firmly clamped in the slot 32, thereby ensuring a reliable connection of the film layer 1.

[0049] In a preferred embodiment, the film layer 1 is an insect-proof net or a plastic film, or a combination of the two. In the southern region, a small-mesh insect-proof net can be used, and in the north, a plastic film or a combination of an insect-proof net and a plastic film can be used. When insulation is needed, the plastic film is covered, and when ventilation is needed, the plastic film is opened or removed.

[0050] A further preferred solution is Figure 3 In the embodiment, an exhaust fan 11 is provided on the film layer 1, and the exhaust fan 11 is fixedly connected to the photovoltaic bracket 100.

[0059] During fastening, the waist-shaped head 95 rotates 90° and snaps into the locking groove 94. During use, the connecting plate 3 is inserted into the sleeve at the edge of the membrane layer 1. A hole is drilled at the location corresponding to the waist-shaped hole 41. Holding the connector 9 on one side, it is passed through the connecting plate 3 and the frame longitudinal beam 4 at the location of the waist-shaped hole 41. The waist-shaped head 95 is then fully extended. After rotating 90 degrees and tightening, the nut is tightened. The waist-shaped head 95 falls into the locking groove 94 of the locking member 93. The nut is then tightened to securely connect the connecting plate 3 and the frame longitudinal beam 4. A spring washer and double nut are then used to secure the connection.
