Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically a large-span solar greenhouse structure with an intermediate earthen wall. Background Technology

[0002] After years of rapid development, traditional solar greenhouse technology has been widely used in agricultural production. However, in the design of long-span greenhouses (such as those over 100 meters), if there is no supporting structure in the middle, the structural stability of the greenhouse becomes a major challenge. It is easily affected by wind and snow loads and deformed, which in turn affects the service life of the greenhouse and the growth environment of the crops inside.

[0003] Furthermore, conventional earthen-walled greenhouses also have significant shortcomings in heat storage efficiency. As the length of the greenhouse increases, the heat storage efficiency of the walls gradually decreases, resulting in uneven temperature distribution inside the greenhouse, which affects the crop growth cycle and yield.

[0004] Meanwhile, the construction process of existing earthen wall greenhouses is relatively complex, and the wall materials are easily eroded by rainwater, resulting in a relatively short service life, which increases maintenance costs and production risks.

[0005] To address this issue, those skilled in the art have proposed a large-span, centrally located earthen wall solar greenhouse structure. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a large-span greenhouse structure with an intermediate earthen wall. An earthen wall is set in the middle as a supporting structure, forming a synergistic force-bearing system with the steel frame. This effectively disperses the load (such as wind and snow pressure) of the long-span greenhouse, significantly reduces the risk of frame deformation, and thus enhances the overall structural stability of the greenhouse.

[0007] A large-span greenhouse structure with a central earthen wall includes a greenhouse rear wall, an east gable wall, a west gable wall, and a central gable wall. A roof beam is installed on the outer side of the top of the greenhouse rear wall, and a covering material is provided on the top of the roof beam.

[0008] It also includes ventilation openings, which are located at the top of the roof beams near the rear wall of the greenhouse. An insulation blanket is installed at the top of the roof beams near the ventilation openings. Multiple greenhouse columns are installed at the bottom of the roof beams, and the bottom of each greenhouse column is provided with a column foundation for connection to the ground. A front ventilation opening is provided at the end of the covering material away from the rear wall of the greenhouse.

[0009] Preferably, the rear wall of the greenhouse is 5.5 meters wide and 5.5 meters high, made of rammed earth, and its surface is covered with a greenhouse west wall long-life film and 500g / ㎡ non-woven fabric, and is fixed with 26# steel wire ground anchors at 2-meter intervals.

[0010] Preferably, a working path is provided in the soil under the foundation of the column near the rear wall of the greenhouse.

[0011] Preferably, the roof beam comprises a lower chord, an upper chord, diagonal braces, and connecting rods. The beams are fixed together by six connecting rods. The lower and upper chords are made of φ322.5mm galvanized steel pipes bent and welded. The diagonal braces are made of φ122.2mm galvanized steel pipes welded together. The foundations at both ends of the roof beam are fixed to the rear wall and the front edge of the greenhouse, respectively.

[0012] Preferably, the covering material is a 0.1mm thick PO film, which is applied over the greenhouse structure.

[0013] Preferably, the ventilation opening is 1 meter wide, covered with 0.1mm thick PO film and 100-mesh insect-proof netting, and has a ventilation opening at the top, which is automatically ventilated and closed by a smart ventilation fan.

[0014] Preferably, the leading-edge air vent is a manually rolled-up ventilation vent with a width of 1 meter, and is equipped with a 100-mesh insect-proof net.

[0015] Preferably, a central gable wall is provided in the middle of the rear wall of the greenhouse, and a work room is provided on the outermost side of the rear wall of the greenhouse.

[0016] Preferably, the intelligent ventilation fan further includes a reel, a traction rope, and a pulley block. The traction rope is fixedly connected to the output end of the reel, and the pulley block is located at one end of the traction rope for sliding connection with the end.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. An earthen wall is set up in the middle as a supporting structure to form a cooperative force-bearing system with the steel frame, which effectively disperses the load of the long-span greenhouse, significantly reduces the risk of frame deformation, and thus enhances the overall structural stability of the greenhouse.

[0019] 2. The earthen walls have excellent heat storage properties, absorbing solar radiation heat during the day and slowly releasing it at night, thus maintaining a nighttime temperature 3-5℃ higher than greenhouses without earthen walls. At the same time, the earthen walls dividing the space help reduce temperature differences within the greenhouse, resulting in a more uniform temperature distribution and a more suitable environment for crop growth.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] Example 1: According to Figures 1-2 As shown, this utility model provides a large-span intermediate earthen wall solar greenhouse structure, including a greenhouse rear wall 1, an east gable wall, a west gable wall and an intermediate gable wall. A roof flower beam 2 is installed on the outer side of the top of the greenhouse rear wall 1, and a covering material 3 is provided on the top of the roof flower beam 2.

[0028] It also includes a ventilation opening 4, which is located at the top of the roof beam 2 near the rear wall 1 of the greenhouse. An insulation blanket 5 is installed at the top of the roof beam 2 near the ventilation opening 4. Multiple greenhouse columns 6 are installed at the bottom of the roof beam 2, and each column 6 has a foundation 7 at its base for connection to the ground. A front vent 8 is located at the end of the covering material 3 furthest from the rear wall 1. The rear wall 1 is 5.5 meters wide and 5.5 meters high. The greenhouse is constructed of compacted earth and covered with a 10-mil long-life film and 500g / ㎡ non-woven fabric for the west wall. It is fixed with 26# steel wire anchors at 2-meter intervals. A working path 9 is provided in the soil under the column foundation 7 near the rear wall 1 of the greenhouse. The roof beam 2 consists of a lower chord 201, an upper chord 202, a tie rod 203, and a connecting rod 204. The beams are fixed together by 6 connecting rods 204. The lower chord 201 and the upper chord 202 of the roof beam are made of φ322 steel. The diagonal tie rod 203 is made of φ122.2mm galvanized steel pipe, which is bent and welded. The foundations at both ends of the roof beam 2 are fixed to the rear wall 1 and the front edge of the greenhouse, respectively. The covering material 3 is a 0.1mm thick PO film, which covers the greenhouse structure. The ventilation opening 4 is 1 meter wide and is covered with a 0.1mm thick PO film and a 100-mesh insect net. A ventilation opening is set at the top, and automatic ventilation and closing are achieved by intelligent ventilation fan A. The front vent 8 is a manually operated roll-up ventilation vent with a width of 1 meter, and is equipped with a 100-mesh insect-proof net. The middle of the rear wall 1 of the greenhouse is also provided with a middle gable wall 11, and the outermost part of the rear wall 1 of the greenhouse is also provided with a work room 13. The intelligent ventilation fan A also includes a roller A01, a traction rope A02, and a pulley group A03. The traction rope A02 is fixedly connected to the output end of the roller A01, and the pulley group A03 is located at one end of the traction rope A02 for sliding connection with the end.

[0029] The intelligent ventilation fan A automatically controls the ventilation volume inside the greenhouse through a preset program or sensor feedback. When the temperature or humidity inside the greenhouse is too high, the drive unit starts, driving the roller A01 to rotate, which in turn pulls the traction rope A02, and through the pulley group A03, pulls the greenhouse film 3 to achieve the ventilation function. When it is necessary to close the ventilation opening, the drive unit reverses, the roller A01 releases the traction rope A02, and the greenhouse film 3 returns to its original position under its own weight or the action of a spring or other reset mechanism, closing the ventilation opening.

[0030] Intelligent Control: The intelligent ventilation fan A can be equipped with temperature and humidity sensors, wind speed sensors, etc., to monitor the environmental conditions inside the greenhouse in real time. By connecting to a control system such as a PLC or microcontroller, it can automatically adjust the ventilation volume according to environmental conditions. Furthermore, the intelligent ventilation fan A also supports remote and manual control modes to meet the needs of different scenarios.

[0031] Working Principle: The main structural components of the greenhouse, including the rear wall 1, west wall 10, east wall 12, central gable wall 11, and roof beams 2, together form a robust overall load-bearing system. The central earthen wall serves as a key supporting structure, forming a closely coordinated force-bearing system with the internal steel frame. This innovative design effectively disperses external forces such as wind and snow loads borne by the long-span greenhouse, significantly reducing the risk of deformation of the greenhouse frame, thus ensuring the overall structural stability of the greenhouse under adverse weather conditions. The central gable wall 11 and other earthen wall structures absorb solar radiation heat during the day and slowly release it at night, thereby increasing the nighttime temperature inside the greenhouse. Compared to greenhouses without earthen walls, this can raise the nighttime temperature by 3-5℃. The insulation blanket 5 covering the outside of the greenhouse is composed of multiple layers of high-efficiency insulation materials, effectively blocking heat loss from the inside of the greenhouse and further enhancing its insulation performance.
