Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, specifically a shading structure for a photovoltaic agricultural greenhouse. Background Technology

[0002] Photovoltaic agricultural greenhouses are a new type of intensive production model that generates solar power by installing photovoltaic modules on the roof of the greenhouse, while simultaneously conducting efficient and ecological agriculture within the greenhouse space. Its core features include the three-dimensional utilization of land resources (without occupying additional arable land), adjusting the light transmittance of the photovoltaic modules to adapt to the different light requirements of crops (such as the cultivation of low-light-tolerant or sun-loving crops like mushrooms, vegetables, and medicinal herbs), and achieving dual benefits of self-sufficiency in electricity for greenhouse temperature control and irrigation facilities, as well as selling surplus electricity to the grid. This model also offers energy-saving and emission-reduction benefits, promoting modern agricultural technology and regional sustainable development through the "agricultural-photovoltaic complementarity" mechanism.

[0003] Currently, for some photovoltaic agricultural greenhouses with an inverted V-shaped top, photovoltaic panels are mainly installed on the side of the top facing the sunlight. Since the photovoltaic panels have low light transmittance, they can provide shading. To meet the needs of light-loving crops and increase light transmittance, gaps are usually left when laying low-transmittance photovoltaic panels to increase light penetration. The gap width is usually between 0.5 and 1 meter, and the direction of the gap is required to be consistent with the solar azimuth angle to reduce overlapping of photovoltaic panel shadows. However, during the use of photovoltaic agricultural greenhouses, the light intensity varies greatly between summer and winter. When the light intensity is high, the reserved gaps can lead to excessively high temperatures and excessive light inside the greenhouse, affecting crop growth and causing crops to suffer from strong light burns or poor growth due to high temperatures. Therefore, we propose a shading structure for photovoltaic agricultural greenhouses. Utility Model Content

[0004] The purpose of this utility model is to provide a shading structure for photovoltaic agricultural greenhouses, which has the advantage of good shading effect. It solves the problem that the light intensity varies greatly between summer and winter, and the gaps left for the direct sunlight during periods of high light intensity can lead to excessively high temperatures and strong light inside the greenhouse, affecting crop growth and causing crops to be scorched by strong light or grow poorly due to high temperatures.

[0008] A fixed block has a rotating rod movably connected to its inner surface via a bearing. The outer surface of the rotating rod has a plurality of worm sleeves and external thread adjusting sleeves evenly distributed. The outer surface of the external thread adjusting sleeve is threadedly connected to a moving block. One end of the rotating rod is fixedly connected to a worm wheel that meshes with the worm sleeve.

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: a shading structure for a photovoltaic agricultural greenhouse, comprising:

[0028] The greenhouse body 1 has multiple support frames 101 installed on its inner side;

[0029] A photovoltaic panel 2 is fixedly connected to a winding seat 4 on one side. A winding shaft 401 and a guide rod 404 are provided on the inner side of the winding seat 4. A shading net 405 is wound around the outer surface of the winding shaft 401. A movable plate 403 located outside the winding seat 4 is fixedly connected to one end of the shading net 405. Guide sliders 402 are fixedly connected to both sides of the movable plate 403.

[0030] The inner surface of the fixed block 3 is movably connected to the rotating rod 301 via a bearing. The outer surface of the rotating rod 301 is equidistantly distributed with a number of worm sleeves 305 and external thread adjusting sleeves 304. The outer surface of the external thread adjusting sleeve 304 is threadedly connected to a moving block 303. One end of the rotating rod 301 is fixedly connected to a worm wheel 406 that meshes with the worm sleeve 305.

[0031] There are multiple photovoltaic panels 2, which are installed at equal intervals on one side of the top of the main body of the greenhouse 1. There are multiple fixing blocks 3, which are fixedly connected to the upper end of one side of the main body of the greenhouse 1. The shade net 405 passes around the outside of the guide rod 404 and passes through one side of the winding seat 4, extending to the outside of the winding seat 4. The number of worm gear sleeves 305 and external thread adjusting sleeves 304 is the same as the number of winding seats 4. The moving block 303 is fixedly connected to one end of the guide slider 402.

[0032] This technical solution: By installing photovoltaic panels 2, the greenhouse body 1 can be shaded. These panels are equidistantly installed on one side of the top of the greenhouse body 1. To ensure light transmittance, gaps are reserved. When it is necessary to reduce the irradiated area of ​​these gaps, the rotating rod 301 rotates with the assistance of the fixing block 3. The rotation of the rotating rod 301 simultaneously drives the worm gear sleeve 305 and the external thread adjusting sleeve 304 to rotate. The rotation of the external thread adjusting sleeve 304 drives the moving block 303 to move, and the moving block 303, via the guide slider 402, drives the moving plate 40. 3. During the movement, the worm gear sleeve 305 rotates, which drives the worm wheel 406 to rotate. The worm wheel 406 rotates, which drives the winding shaft 401 to rotate. The winding shaft 401 rotates, which simultaneously unwinds the shade net 405. With the assistance of the guide rod 404, the moving plate 403 drives the unwinding shade net 405 to completely or selectively block the gap, thereby reducing the light intensity entering the greenhouse body 1 through the gap and reducing the light transmittance. If it is necessary to restore the blocking area of ​​the gap, simply reverse the rotation of the rotating rod 301.

[0033] It should be noted that the shade net 405 used in this structure has a certain degree of elasticity and is relatively thin. At the same time, the gap width is usually between 0.5 and 1 meter, which makes the adjustment width small. Small-range changes in the shape of the shade net 405 do not affect the adjustment. The distance between the moving block 303 and the surface of the external thread adjusting sleeve 304 is consistent with the distance between the sunshade net 405 being wound and unwound by the winding shaft 401. Meanwhile, the setting of the guide slider 402 can ensure the smooth movement of the moving plate 403. Similarly, protective covers can be added to the outside of the external thread adjusting sleeve 304, worm sleeve 305, worm wheel 406 and moving block 303, and maintenance is required. This is a mature and conventional method in the prior art, so it will not be described in detail here.

[0034] Example 2

[0035] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a rotating arm 302 is fixedly connected to one side of the rotating rod 301, and a rotating handle is fixedly connected to the lower end of one side of the rotating arm 302.

[0036] This technical solution: By setting up the rotating arm 302, the user can easily rotate the rotating rod 301 by rotating the handle and rotating the arm 302, which is convenient for the user to operate.

[0037] It is understandable that the rotating arm 302 can also be set on both sides of the rotating rod 301, so that it is easier for two people to drive the rotating rod 301 through the rotating arm 302. Similarly, a motor drive can be added to the middle of the rotating rod 301 to avoid the time-consuming and laborious situation of manual driving. This structure uses manual driving, which is low in cost.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
