Description

Technical Field

[0001] This utility model relates to the field of Ganoderma lucidum spore powder collection technology, specifically to photovoltaic modules for greenhouses. Background Technology

[0002] The core of a yin-yang greenhouse consists of three basic parts: the sun greenhouse, the shade greenhouse, and a shared central wall. The sun greenhouse serves as the planting area for light-loving crops, with its light-receiving side facing south, and is usually a single-slope greenhouse structure. The shade greenhouse is built against the central wall, with its light-receiving side facing north, and is the cultivation area for shade-tolerant crops. The shared central wall is the key structure connecting the sun greenhouse and the shade greenhouse, and is usually made of brick and concrete, serving as both the north wall of the sun greenhouse and the south wall of the shade greenhouse.

[0003] As the core area for growing sun-loving crops, the transparent plastic film and other light-transmitting coverings in greenhouses are crucial for ensuring crop sunlight exposure, but these materials are relatively weak in impact resistance. In traditional photovoltaic greenhouses with alternating shade and shade, rainwater easily slides directly off the surface of the photovoltaic panels in the shaded area, impacting the light-transmitting film in the shaded area at high speed. Over time, this can easily lead to film damage and accelerated aging, increasing maintenance costs and affecting crop growth due to reduced light transmittance. Therefore, it is necessary to propose a photovoltaic module for greenhouses. Utility Model Content

[0004] The purpose of this invention is to provide photovoltaic modules for greenhouses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module for a greenhouse, comprising a central wall, a sun shed installed on one side of the central wall, a shade shed installed on another side of the central wall, a drainage ditch on the upper surface of the shade shed, an installation frame fixedly installed on the upper surface of the shade shed, a photovoltaic panel fixedly installed at the upper end of the installation frame, a fixing block fixedly connected to the lower surface of the photovoltaic panel, a fixing hole through the fixing block, a fixing rod slidably connected within the fixing hole, a water-blocking mesh plate fixedly installed on the fixing rod, and an elastic component provided within the fixing hole.

[0006] Preferably, the elastic component includes an annular groove, which is formed on the wall of the fixing hole, and a fixing ring is slidably connected in the annular groove, and a spring is sleeved on the wall of the fixing rod.

[0007] Preferably, the fixing ring is fixedly sleeved on the wall of the fixing rod, one end of the spring is fixedly connected to the fixing ring, and the other end of the spring is fixedly connected to the wall of the annular groove.

[0008] Preferably, the water-blocking mesh is attached to the lower end of the photovoltaic panel, and the upper end of the water-blocking mesh extends upward and is higher than the lower surface of the photovoltaic panel.

[0009] Preferably, the drainage ditch is located directly below the water-retaining mesh plate.

[0010] Preferably, the upper end of the intermediate wall penetrates the upper surface of the sunshade and the shade and extends upward.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: through the graded protection design of the water-blocking mesh, when the rainfall is small, the water-blocking mesh uses its "absorption-guidance" effect to prevent rainwater from directly impacting the membrane; when the rainfall is large, the water-blocking mesh adapts to the impact force and guides the rainwater into the drainage ditch through the gaps, completely blocking the direct contact between rainwater and the sunshade light-transmitting membrane, fundamentally solving the problem of membrane damage caused by rainwater impact, and significantly extending the service life of the sunshade light-transmitting facilities and the overall structure.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-3 As shown, this utility model provides the following technical solution: Example 1: A photovoltaic module for a greenhouse includes a central wall 1, a sunshade 2 installed on one side of the central wall 1, a shade shed 3 installed on one side of the central wall 1, a drainage ditch 4 on the upper surface of the shade shed 3, an mounting frame 5 fixedly installed on the upper surface of the shade shed 3, a photovoltaic panel 6 fixedly installed at the upper end of the mounting frame 5, a fixing block 7 fixedly connected to the lower surface of the photovoltaic panel 6, a fixing hole 8 penetrating through the fixing block 7, a fixing rod 9 slidably connected in the fixing hole 8, a water-blocking mesh 10 fixedly installed on the fixing rod 9, and an elastic component provided in the fixing hole 8; When using it, the following steps are included: First, when it rains and the amount of rain is small, the rainwater on the photovoltaic panel 6 will flow down the photovoltaic panel 6 and impact the water-blocking mesh 10. The water-blocking mesh 10 will absorb the rainwater and then slide down directly inside the water-blocking mesh 10 and fall into the drainage ditch 4 to be discharged, thus preventing the rainwater from sliding down the photovoltaic panel 6 directly and impacting the transparent plastic film of the canopy 2. The second step involves the following: When it rains heavily, the water-blocking mesh 10 experiences a significant impact. This impact pulls the fixing rod 9, which in turn pulls the fixing ring 12. The fixing ring 12 then compresses the spring 13, allowing the fixing rod 9 to move a certain distance. This releases the water-blocking mesh 10 from contact with the photovoltaic panel 6, creating a gap between them. This allows subsequent rainwater to flow down through the gap and into the drainage ditch 4, preventing it from sliding directly down the photovoltaic panel 6 and impacting the transparent plastic film of the awning 2.

[0016] Example 2: The technical solutions in this example that differ from Example 1 include: The elastic component includes an annular groove 11, which is formed on the wall of the fixing hole 8. A fixing ring 12 is slidably connected within the annular groove 11. A spring 13 is sleeved on the wall of the fixing rod 9. The fixing ring 12 is fixedly sleeved on the wall of the fixing rod 9. One end of the spring 13 is fixedly connected to the fixing ring 12, and the other end of the spring 13 is fixedly connected to the groove wall of the annular groove 11. The spring 13 pushes the fixing ring 12 under the support of the annular groove 11, while the fixing ring 12 pulls the fixing rod 9, and the fixing rod 9 pulls the water-blocking net. The panel 10 abuts against the photovoltaic panel 6. The water-blocking mesh 10 is fitted to the lower end of the photovoltaic panel 6, and the upper end of the water-blocking mesh 10 extends upward and is higher than the lower surface of the photovoltaic panel 6. The water-blocking mesh 10 blocks the rainwater flowing from the photovoltaic panel 6. The drainage ditch 4 is located directly below the water-blocking mesh 10. The rainwater blocked by the water-blocking mesh 10 will flow into the drainage ditch 4. The upper end of the intermediate wall 1 penetrates the upper surface of the sunshade 2 and the shade 3 and extends upward. The extended intermediate wall 1 blocks rainwater, thus adding an extra layer of protection.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
