Description

A prefabricated earth-storage solar greenhouse Technical Field

[0001] This invention relates to the field of greenhouse technology, specifically to a prefabricated earth-heat-storage solar greenhouse. Background Technology

[0002] A solar greenhouse is a highly efficient and energy-saving agricultural facility. It primarily relies on its south-facing, light-transmitting surface to absorb solar energy, and uses thick earthen back walls and insulation materials to store and retain heat, reducing the temperature difference between day and night. This allows for the cultivation of vegetables, flowers, and other crops in winter with little or no additional heating. A solar greenhouse mainly consists of earthen walls and a steel frame structure. The earthen walls primarily serve to store, insulate, and support the structure, utilizing the thermal inertia of the soil to absorb and store solar energy during the day and slowly release heat at night to maintain a stable greenhouse temperature. Simultaneously, the earthen walls support the greenhouse frame.

[0003] The earthen walls of the solar greenhouse adopt a "metal frame + soil filling" structure. First, a trapezoidal or rectangular frame is welded from metal to serve as the supporting structure of the wall. Then, steel mesh and geotextile are laid inside the frame and filled with soil. Compared with pure earthen walls, this structure saves land area while retaining the heat storage and insulation properties of the soil, making it especially suitable for areas with scarce land or loose soil.

[0004] The existing soil-based thermal storage greenhouses have gradually revealed their shortcomings during use, mainly in the following aspects:

[0005] First, metal frames have low applicability. Specifically, due to the significant climate differences between the north and south of my country, the thickness of greenhouse walls needs to be designed according to local conditions. For example, in frigid regions, 3-meter-thick earthen walls are required to enhance heat storage and insulation, while in temperate regions, only 1.5 meters is needed. Existing metal frame structures mostly use welding processes to create frames of fixed thickness. The thickness of the walls formed after filling with soil cannot be adjusted, making it difficult for metal frames of the same specifications to adapt to the insulation requirements of different climate zones, thus reducing the applicability of metal frames.

[0006] Secondly, the soil filling process is complicated. Specifically, the height of the metal frame structure is usually 4 meters. Due to the height of the metal frame, the operation is extremely complicated when using large equipment to fill the soil.

[0007] Third, the welding and assembly process is complex. Specifically, during the installation of the metal frame, the metal pipes need to be assembled and welded one by one on the construction site. Therefore, the assembly process is tedious and complicated, resulting in a long construction period.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a prefabricated earthen heat storage greenhouse. This greenhouse can adjust the thickness of the metal frame structure according to the climate conditions of the area of ​​use, thereby realizing the function of adaptive adjustment of the earthen wall thickness and improving the applicability of the metal frame.

[0010] The upper part of the metal frame structure of the greenhouse adopts a flip-up design, which can reduce the overall structural height in the early stage of filling the soil. After the soil in the lower area is filled, the upper part of the frame flips back to its original position, and only the higher area needs to be filled later, which simplifies the soil filling process.

[0011] The metal frame structure of the greenhouse adopts a modular and detachable design, making the assembly process simple.

[0012] To address the above problems, the present invention provides the following technical solution:

[0013] A prefabricated soil-based thermal storage greenhouse includes a concrete foundation. Several metal frames are horizontally arranged side-by-side within the concrete foundation. Adjacent metal frames are detachably connected. Each metal frame has a detachably mounted steel frame at its end. Each metal frame includes a support base. Horizontally movable support plates are provided at opposite ends of the support bases. Two support plates are fixedly connected to the top of each support plate. A rotating plate is hinged to the top of each support plate. The two support plates and the two rotating plates are fixedly connected by several connecting plates. Two mounting plates are fixedly installed on the top of the support base. Several first hinge plates are hinged to the ends of the mounting plates. Several second hinge plates are hinged to the ends of the support plates and rotating plates. The first and second hinge plates are hinged together, and their hinge positions are adjustable. A fixing plate is fixedly connected to the upper end of the mounting plate, and a positioning plate is fixedly connected to the end of the rotating plate. The positioning plate is fixedly connected to the fixing plate, and its fixed position is adjustable.

[0014] As an optimized solution, the top of the support base is provided with several sliding grooves, and a sliding plate is horizontally slidably arranged in the sliding grooves. One end of the sliding plate extends to the outside of the support base and is fixedly connected to the support plate.

[0015] As an optimized solution, both the tray and the sliding plate are provided with threaded feet at their bottoms for threaded connection, and the sliding plate is provided with several mounting threaded holes at its bottom.

[0016] As an optimized solution, the top of the sliding plate is provided with a positioning bolt that is threadedly connected to it, and the bottom of the sliding groove is provided with several positioning threaded holes.

[0017] As an optimized solution, the first hinge plate is hinged to the second hinge plate by bolts and nuts, and the end of the second hinge plate is provided with several through-hole adjustment holes.

[0018] As an optimized solution, the positioning plate is fixedly connected to the fixing plate by bolts and nuts, and the fixing plate has several through positioning holes at its end.

[0019] As an optimized solution, the two adjacent support plates and the two adjacent rotating plates are detachably connected by bolts and nuts.

[0020] As an optimized solution, the steel frame is detachably connected to the rotating plate by bolts and nuts.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. When adjusting the thickness of the metal frame, drag the support plates on both sides of the support base to match the required thickness of the earthen wall. Screw the positioning bolts into the corresponding positioning threaded holes and limit the sliding plate. Select the appropriate adjustment hole and hinge the second hinge plate on the support plate to the first hinge plate using bolts and nuts. Select the appropriate installation threaded hole and install the threaded support foot on the bottom of the sliding plate. When assembling the large metal frame, place several metal frames with adjusted low-level thickness into the concrete foundation and connect adjacent support plates using bolts and nuts. Several metal frames are connected in sequence to form the large metal frame. Then, lay steel mesh and geotextile on the low-level inner wall of the enclosed large metal frame. Soil is filled into the lower area of ​​the metal frame. After the soil filling is completed, the rotating plate is rotated upward and the positioning hole at the appropriate position is selected to fix the positioning plate and the fixing plate with bolts and nuts. The adjustment hole at the appropriate position is selected to hinge the second hinge plate on the rotating plate to the first hinge plate with bolts and nuts. Then, the two adjacent rotating plates are connected with bolts and nuts. Then, steel mesh and geotextile are laid into the upper inner wall of the enclosed large metal frame. Workers fill soil into the upper area of ​​the large metal frame. This greenhouse can adjust the thickness of the metal frame according to the climate conditions of the area of ​​use, thereby realizing the function of adaptive adjustment of the soil wall thickness and improving the applicability of the metal frame.

[0023] 2. The upper part of the metal frame of the greenhouse adopts a flip-up design, which can reduce the overall structural height in the early stage of filling the soil. After the soil in the lower area is filled, the upper part of the frame flips back to its original position. Only the higher area needs to be filled later, which simplifies the soil filling process.

[0024] 3. The first and second hinge plates, which are hinged together, as well as the positioning plate and the fixing plate that are fixedly connected, can enhance the compressive strength of the support plate and the rotating plate. The threaded feet at the bottom of the support plate and the sliding plate can enhance the support strength of the support plate and the sliding plate, thereby improving the practicality of the greenhouse.

[0025] 4. The metal frame structure of this greenhouse adopts a modular and detachable design, making the assembly process simple. Attached Figure Description

Several second hinge plates 13 are hinged to the ends of the support plates 6 and the rotating plates 5. The first hinge plates 16 and the second hinge plates 13 are hinged together and their hinge positions are adjustable. A fixing plate 21 is fixedly connected to the upper end of the mounting plate 17. A positioning plate 19 is fixedly connected to the end of the rotating plate 5. The positioning plate 19 is fixedly connected to the fixing plate 21 and its fixed position is adjustable.

[0037] The top of the support base 11 is provided with several sliding grooves 10, and a sliding plate 7 is horizontally slidably arranged in the sliding grooves 10. One end of the sliding plate 7 extends to the outside of the support base 11 and is fixedly connected to the support plate 8.

[0038] Both the support plate 8 and the sliding plate 7 are provided with threaded feet 9 at their bottoms for threaded connection, and the sliding plate 7 is provided with several threaded holes 18 at its bottom.

[0039] The top of the sliding plate 7 is provided with a positioning bolt 14 that is threadedly connected to it, and the bottom of the sliding groove 10 is provided with several positioning threaded holes 15.

[0040] The first hinge plate 16 is hinged to the second hinge plate 13 by bolts and nuts. The end of the second hinge plate 13 is provided with several through-hole adjustment holes 12.

[0043] The steel frame 3 is detachably connected to the rotating plate 5 by bolts and nuts.

[0044] The working principle of this device is as follows:

[0045] When adjusting the thickness of the metal frame 2, drag the support plates 8 on both sides of the support base 11 to match the required earth wall thickness. Screw the positioning bolts 14 into the corresponding positioning threaded holes 15 and limit the sliding plate 7. Select the appropriate adjustment hole 12 to hinge the second hinge plate 13 on the support plate 6 to the first hinge plate 16 with bolts and nuts. Select the appropriate installation threaded hole 18 to install the threaded support 9 at the bottom of the sliding plate 7. When assembling the large metal frame, place several metal frames 2 with adjusted low-position thickness into the concrete foundation 1 and connect adjacent support plates 6 with bolts and nuts. Several metal frames 2 are connected in sequence to form the large metal frame. Then, lay steel mesh and geotextile on the low-position inner wall of the enclosed large metal frame. Workers fill soil into the lower area of ​​the metal frame. After the soil is filled, the rotating plate 5 is rotated upwards and the positioning hole 20 is selected at a suitable position to fix the positioning plate 19 and the fixing plate 21 with bolts and nuts. The adjustment hole 12 is selected at a suitable position to hinge the second hinge plate 13 on the rotating plate 5 to the first hinge plate 16 with bolts and nuts.

Workers fill soil into the upper area of ​​the large metal frame. The greenhouse can adjust the thickness of the metal frame 2 according to the climate conditions of the area, thereby realizing the function of adaptive adjustment of the soil wall thickness and improving the applicability of the metal frame 2.

[0046] The upper part of the metal frame 2 of the greenhouse adopts a flip-up design, which can reduce the overall structural height in the early stage of filling the soil. After the soil in the lower area is filled, the upper part of the frame flips back to its original position, and only the higher area needs to be filled later, which simplifies the soil filling process.

[0047] The first hinge plate 16 and the second hinge plate 13 are hinged together, and the positioning plate 19 and the fixing plate 21 are fixedly connected, which can strengthen the compressive strength of the support plate 6 and the rotating plate 5. The threaded support feet 9 at the bottom of the support plate 8 and the sliding plate 7 can strengthen the support strength of the support plate 8 and the sliding plate 7, thereby improving the practicality of the greenhouse.

[0048] The metal frame structure of the greenhouse adopts a modular and detachable design, making the assembly process simple.
