Description

Technical Field

[0001] This utility model relates to the field of greenhouses, specifically a novel agricultural photovoltaic device based on organic solar cells. Background Technology

[0002] Greenhouse cultivation is a modern agricultural method that utilizes specific facilities and technologies to create a suitable growing environment for crops, thereby achieving high-efficiency crop production. A typical greenhouse includes a frame structure, covering materials, a ventilation system, a temperature control system, and an irrigation system. The frame structure is often made of materials such as steel pipes and wood. The ventilation system regulates indoor air circulation through vents and exhaust fans. The temperature control system includes heating and cooling equipment, such as heaters, air conditioners, shade nets, and evaporative cooling pads, to maintain a suitable temperature. The irrigation system provides water to the crops through drip irrigation, sprinkler irrigation, and other methods.

[0003] Regarding patents related to greenhouses, a search revealed that CN217136209U, authorized publication number, discloses a greenhouse for growing Anoectochilus roxburghii with temperature control function. The text includes a greenhouse body, a control unit, a temperature sensor, and a greenhouse heating component. The feature is that the outer walls of the control unit and the temperature sensor are fixedly connected to the inner wall of the greenhouse body, and the greenhouse body has a fixed frame connected inside.

[0004] Although the above-mentioned device has the function of automatic snow removal and can improve the structural strength of the roof of the Golden Thread Lotus cultivation greenhouse, in actual use, the load equipment inside the cultivation greenhouse needs to be powered by the mains electricity. The usual solution is to install photovoltaic panels on the roof of the cultivation greenhouse. However, photovoltaic panels are not transparent, which affects the normal photosynthesis of plants inside the cultivation greenhouse, inhibits crop growth, and reduces crop yield and quality.

A base is fixedly installed at the bottom of the agricultural greenhouse body. A temperature control system, a battery energy storage device, and an irrigation system are respectively installed on the side walls of the agricultural greenhouse body. A top beam mechanism is fixedly installed on the top of the agricultural greenhouse body. The top beam mechanism includes a longitudinal beam fixedly connected to the top of the side wall of the agricultural greenhouse body. A crossbeam is fixedly installed at the end of the longitudinal beam. A support column is fixedly installed on the middle surface of the crossbeam. A top beam is fixedly installed at the end of the support column away from the crossbeam. A protective cover is provided between the top beam and the longitudinal beam.

[0007] Furthermore, each of the two opposite side walls of the agricultural greenhouse body has three sets of equidistant ventilation windows. The temperature control system and irrigation system inside the agricultural greenhouse body are powered by a battery energy storage device, which stores energy through organic solar cell modules.

[0008] Furthermore, the top beam mechanism includes longitudinal beams, a top beam, a protective cover, a light-receiving panel, a crossbeam, a support column, a mounting frame, and a support rib frame. The longitudinal beams are set in two groups and fixed on both sides of the upper part of the agricultural greenhouse body. At the same time, the two groups of longitudinal beams are evenly supported and fixed by multiple groups of equally distributed crossbeams.

[0009] Furthermore, each of the multiple sets of crossbeams is fixedly connected to a support column, and the support columns, crossbeams, and the light-receiving panels at the ends of the top beam mechanism form a right-angled triangle.

[0010] Furthermore, the light-receiving panel is divided into two groups and is respectively set on both sides of the top beam. Multiple sets of mounting brackets are evenly installed on the light-receiving panel, and a support rib is fixedly set at the bottom of the mounting bracket. One end of the mounting bracket is screwed into the mounting groove opened on the side wall of the top beam, and the other end of the mounting bracket is screwed into the mounting groove opened on the side wall of the longitudinal beam. The cross-section of the longitudinal beam is set in an "L" shape, and the cross-section of the top beam is set in a "T" shape.

[0011] Furthermore, the mounting frame is adapted to the size of the organic solar cell module, and the organic solar cell module is screwed inside the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses multiple sets of organic solar cell modules combined together to form the roof of an agricultural greenhouse. The organic solar cell modules have a unique wavelength-selective absorption spectrum, which can absorb infrared light and transmit some visible light, thereby ensuring photovoltaic power generation efficiency while reducing the obstruction of visible light required for crop growth. This not only effectively improves land use efficiency and achieves the dual benefits of photovoltaic power generation and agricultural production, but also improves the lighting environment inside the greenhouse, promotes crop growth, and increases crop yield and quality. It also reduces dependence on traditional power grid electricity and lowers the electricity cost of agricultural greenhouses.

[0026] Please see Figure 1-9 This utility model provides a novel agricultural photovoltaic device based on organic solar cells, including an organic solar cell module 6, which covers the top of an agricultural greenhouse body 1. A base 3 is fixedly installed at the bottom of the agricultural greenhouse body 1. A temperature control system 4, a battery energy storage device 41, and an irrigation system 42 are respectively installed on the side walls of the agricultural greenhouse body 1. A top beam mechanism 5 is fixedly installed on the top of the agricultural greenhouse body 1. The top beam mechanism 5 includes a longitudinal beam 51 fixedly connected to the top of the side wall of the agricultural greenhouse body 1. A crossbeam 55 is fixedly installed at the end of the longitudinal beam 51. A support column 56 is fixedly installed on the middle surface of the crossbeam 55. A top beam 52 is fixedly installed at the end of the support column 56 away from the crossbeam 55. A protective cover 53 covers the space between the top beam 52 and the longitudinal beam 51.

[0027] Working Principle: In actual use, multiple sets of organic solar cell modules 6 are evenly installed on the top of the agricultural greenhouse body 1. These modules combine to form the roof of the greenhouse body 1. The organic solar cell modules 6 possess a unique wavelength-selective absorption spectrum, capable of absorbing infrared light while transmitting some visible light. This ensures photovoltaic power generation efficiency while reducing shading of the visible light required for crop growth. Furthermore, they possess good flexibility and plasticity, allowing for design into various shapes and sizes according to actual needs, providing more possibilities for the application of photovoltaic devices in agriculture. Applying this device to agricultural greenhouses or sheds not only effectively improves land use efficiency and achieves the dual benefits of photovoltaic power generation and agricultural production, but also improves the lighting environment inside the greenhouse, promotes crop growth, and increases crop yield and quality. It features lightweight, low cost, and high flexibility, promoting plant growth and achieving efficient utilization of both land and light resources. The organic solar cell modules 6 can be made into semi-transparent cells with high light transmittance and can be applied with multiple... The greenhouse features multiple colors to ensure sufficient indoor lighting while simultaneously collecting solar energy from the external environment. This enables smarter, more efficient, and greener energy utilization, promotes crop growth, and improves crop yield and quality. The interior of the greenhouse body 1 is illuminated by multiple sets of LED energy-saving lamps 521, which are compatible with low-voltage power supplies from organic solar cells. The organic solar cell modules 6 selectively absorb wavelengths, reducing the impact on crop photosynthesis and ensuring crop yield and quality. The battery storage unit 41 can be configured to be used in sufficient quantities as needed. Connected to the organic solar cell modules 6, irrigation system 42, temperature control system 4, and LED energy-saving lamps 521 via a control circuit, the battery storage unit 41 stores the electricity generated by the organic solar cell modules 6, supplying power to the irrigation system 42, temperature control system 4, and LED energy-saving lamps 521. This reduces reliance on traditional power grids and lowers the electricity costs of the agricultural greenhouse. In areas with ample sunlight, the solar cell modules can generate enough electricity to meet the operational needs of the equipment within the greenhouse, achieving energy self-sufficiency.

[0028] As a preferred implementation, three sets of equidistant ventilation windows 2 are provided on the two opposite side walls of the agricultural greenhouse body 1. The temperature control system 4 and irrigation system 42 inside the agricultural greenhouse body 1 are powered by a battery energy storage device 41, which stores energy through organic solar cell modules 6.

[0029] The top beam mechanism 5 includes longitudinal beams 51, top beams 52, protective covers 53, light-receiving panels 54, crossbeams 55, support columns 56, mounting frames 57, and support ribs 58. The longitudinal beams 51 are set in two groups and fixed on both sides of the upper part of the agricultural greenhouse body 1. At the same time, the two groups of longitudinal beams 51 are evenly supported and fixed by multiple groups of equally distributed crossbeams 55.

[0030] Multiple sets of crossbeams 55 are fixedly connected to support columns 56 at their tops. The support columns 56, crossbeams 55 and light-receiving panels 54 at the ends of the top beam mechanism 5 form a right triangle.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: The top of the agricultural greenhouse body 1 is supported and fixed by longitudinal beams 51, top beams 52, cross beams 55, and support columns 56. The top beam mechanism 5 forms a triangle, which provides stability and ensures the overall stability of the top beam mechanism 5. Simultaneously, multiple sets of organic solar cell modules 6 are positioned and installed using mounting frames 57 and support ribs 58. When the multiple sets of organic solar cell modules 6 are installed inside the mounting frame 57, they are supported by the support ribs 58. The support ribs 58 can evenly distribute the pressure borne by the organic solar cell modules 6 onto the mounting frame 57, avoiding excessive local pressure. This is particularly important for greenhouse roofs subjected to external forces such as wind and snow, effectively preventing the organic solar cell modules 6 from cracking or being damaged due to uneven stress, thus extending their service life. The mounting frame 57 and the support ribs 58 form a stable structural system, providing solid support for the organic solar cell modules 6 and enhancing their strength. The entire greenhouse roof is strong and rigid; even in severe weather conditions, such as strong winds or blizzards, it ensures that the organic solar cell module 6 remains in place without displacement or deformation, guaranteeing the safety of the greenhouse. The support frame 58 plays a positioning role within the mounting frame 57, making the installation of the organic solar cell module 6 more convenient and accurate. Installers can quickly place the organic solar cell module 6 in the appropriate position according to the position and spacing of the support frame 58, improving installation efficiency. At the same time, this precise positioning also helps to ensure uniform spacing between the panels, avoiding gaps that are too large or too small, which would affect power generation efficiency. The support frame 58 can also serve as a passage for maintenance personnel to walk or operate on the mounting frame 57, facilitating the inspection, cleaning, repair, and other maintenance work of the organic solar cell module 6. To increase the waterproofness of the top of the agricultural greenhouse body 1, sealing pads are installed on the organic solar cell module 6, the mounting frame 57, and at the mounting frame 57.

[0032] In a preferred embodiment, the light-receiving panel 54 is divided into two groups and respectively disposed on both sides of the top beam 52. Multiple sets of mounting brackets 57 are evenly installed on the light-receiving panel 54, and a support rib 58 is fixedly disposed at the bottom of the mounting bracket 57. One end of the mounting bracket 57 is screwed into the mounting groove opened on the side wall of the top beam 52, and the other end of the mounting bracket 57 is screwed into the mounting groove opened on the side wall of the longitudinal beam 51. The longitudinal beam 51 has an "L" shaped cross section, and the top beam 52 has a "T" shaped cross section.

[0033] The mounting bracket 57 is adapted to the size of the organic solar cell module 6, and the organic solar cell module 6 is screwed inside the mounting bracket 57. Meanwhile, the bottom of the organic solar cell module 6 is supported by the support frame 58, which consists of five sets of horizontal ribs and a single set of longitudinal ribs.

[0034] The longitudinal beam 51 has a connecting groove A511 inside, and the top beam 52 has a connecting groove B522 inside. Multiple sets of equidistant LED energy-saving lamps 521 are evenly installed at the bottom of the top beam 52. A connecting strip A531 is fixedly installed at one end of the protective cover 53, and a connecting strip B532 is fixedly installed at the other end of the protective cover 53. The connecting strip A531 is inserted into the inside of the connecting groove A511, and the connecting strip B532 is inserted into the inside of the connecting groove B522. The protective cover 53 covers the light-receiving panel 54 and is positioned and assembled by the connecting strip A531, connecting groove A511, connecting strip B532, and connecting groove B522.

[0035] like Figure 5 , Figure 6 , Figure 7 and Figure 9 The protective cover 53 covers the light-receiving panel 54 and is positioned and assembled using docking strips A531, docking grooves A511, docking strips B532, and docking grooves B522. The installation of the protective cover 53 requires two conditions: first, the battery storage device 41 must be fully charged; second, it must be installed before severe weather such as hail is predicted. This achieves the purpose of preventing physical damage to the organic solar cell module 6 and extending its service life. The pull-out, detachable design allows workers to easily open the protective cover 53 for inspection, repair, or cleaning of the organic solar cell module 6, and easily reposition it after operation. When the organic solar cell module 6 is not generating electricity, the protective cover 53 can prevent dust, leaves, and other debris from falling onto it.

[0036] Both sets of longitudinal beams 51 have connecting grooves A511 inside. When it rains, rainwater flows up and down the organic solar cell module 6 and enters the connecting grooves A511. The water inside the connecting grooves A511 can be discharged from the openings at the ends of the connecting grooves A511. This achieves organized drainage of rainwater falling from the agricultural greenhouse body 1. Organized drainage can prevent rainwater from forming runoff on the ground around the greenhouse, prevent water flow from eroding the soil around the greenhouse, thereby reducing soil erosion and maintaining the stability and fertility of the soil around the greenhouse. There is no standing water or mud around the greenhouse, which is convenient for workers to carry out daily agricultural operations. It avoids the formation of a damp environment around the greenhouse, thereby reducing the breeding and spread of pests and diseases such as mosquitoes and germs, which is conducive to creating a relatively healthy environment inside and outside the greenhouse and reducing the possibility of crop pests and diseases.
