Description

Technical Field

[0001] This application relates to the field of agricultural greenhouse equipment technology, specifically to a passive ultra-low energy consumption solar greenhouse. Background Technology

[0002] With the rapid development of smart agriculture, greenhouses, as important facilities for ensuring efficient crop cultivation, are seeing a growing market demand for heating, especially in cold regions or during low-temperature seasons. Ordinary greenhouses struggle to maintain the suitable temperatures required for crop growth, while solar greenhouses solve this critical problem. They provide a stable growing environment for various crops such as fruits, vegetables, and flowers, effectively breaking the limitations of seasons and regions on agricultural planting, significantly increasing the year-round utilization rate of greenhouses, and further improving the economic benefits of agricultural production by ensuring crop quality and yield. As a result, they have become an indispensable and important facility in the development of modern agriculture.

[0003] In actual agricultural production, solar greenhouses have been widely used in many places and play an important role in the off-season cultivation of fruits and vegetables such as strawberries and tomatoes, helping growers to achieve staggered market entry of fruits and vegetables and increase planting income.

[0004] Traditional greenhouse equipment requires burning conventional fuels such as coal and straw. The heat energy generated after combustion is then converted into heat energy that can be directly used for greenhouse heating through processes such as compression and heat exchange. However, this heating method emits a large amount of flue gas during combustion, which contains a large number of harmful gases and dust particles. These harmful gases and dust particles, when directly emitted into the air, will affect air quality. Part of the energy from combustion is converted into light energy and part into heat energy, and only a portion of this heat energy can be collected, resulting in very low utilization efficiency of the heat energy generated during combustion. Therefore, a passive ultra-low energy consumption solar greenhouse was invented to address this deficiency. Utility Model Content

Both ends of the dehumidification duct extend out of the heat storage wall and are located inside the structure. A duct fan is installed at the end of the dehumidification duct that is higher than the heat storage wall.

[0007] Furthermore, the organic fertilizer fermentation tank includes a greenhouse, which is set up in the planting area inside the greenhouse.

[0019] As attached Figure 1 As shown, the organic fertilizer fermentation tank includes a greenhouse 401, which is hollow inside. The greenhouse 401 is set up in the planting area 1 inside the greenhouse. A fermentation tank 402 is set inside the greenhouse 401. Insulation boards 404 are attached to the sides of the greenhouse 401 surrounding the fermentation tank 402.

The outer surface of the inner beam frame 712 is covered with an insulation film and an insulation blanket. The inner beam frame 712 is fixedly connected to the embedded part 701, and the outer beam frame 709 is fixedly connected to the second positioning pile 706. 06 Fixed connection: A first reinforcing rod 708 is connected to a portion of the outer arch horizontal tie tube 703, which provides mutual support between two adjacent outer arch horizontal tie tubes 703. A second reinforcing rod 711 is connected to a portion of the inner arch horizontal tie tube 707, and the other end of the second reinforcing rod 711 is installed on the first movable column 702 or the second movable column 710.

The insulation film and insulation blanket on the inner beam frame 712 are wrapped around the outer surface of the roller 705. The insulation film of the inner beam frame 712 is a 12-mil PO film, and the insulation blanket has seven layers.

[0022] As attached Figure 1 As shown, the portion of the outer beam frame 709 located above the roller 705 has an opening. The outer surface of the outer beam frame 709 is wrapped from the inside out with wire mesh, Dutch mesh, insect netting, and insulation film.

The transmission part of the electric film roller 704 is connected to the insulation film on the outer surface of the outer beam frame 709.

[0023] The working principle of this device is as follows.

[0024] (i) Gas is introduced into the fermentation tank 402 through the ventilation pipe 3, thereby providing gas for the fermentation of the fermentation tank 402. The fermentation tank 402 generates heat during fermentation, and the generated heat heats the water in the circulating water pipe 503. The heated water is sent into the underfloor heating pipe 501 through the water distributor 502, and the underfloor heating pipe 501 heats the inside of the shed. At the same time, when the circulating water pipe 503 passes through the heat storage wall 2, part of the heat is absorbed and stored by the heat storage material in the heat storage wall 2.

[0025] (ii) During the day, sunlight shines on the windows, and heat accumulates at the ridge. The heat accumulated at the ridge circulates through the dehumidification pipe 601. Not only is the heat absorbed by the heat storage material, but the water vapor also condenses into liquid water due to the cooling. Finally, it is collected and discharged through the condensate collection pipe 604. During the day, the electric film rolling device 704 is activated. The transmission part of the electric film rolling device 704 drives the insulation film on the outer surface of the outer beam 709 to retract, thereby exposing the window opening and allowing sunlight to shine into the interior of the greenhouse through the window opening. At night, the electric film rolling device 704 is activated. The transmission part of the electric film rolling device 704 drives the insulation film on the outer surface of the outer beam 709 to retract and cover the window opening, thereby providing insulation.

[0026] (iii) During the cooling process at night, as the temperature inside the shed decreases, a temperature difference is formed between the shed and the heat storage material. The heat storage material will gradually release the stored heat. At the same time, the pipe fan 602 rotates in the opposite direction, blowing the heated air in the dehumidification pipe 601 into the shed through the pipe fan 602, thereby maintaining the temperature inside the shed at a constant state.

[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
