Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to an assembled soil heat storage solar greenhouse. Background Art

[0002] A solar greenhouse is a highly efficient and energy-efficient agricultural facility. It primarily absorbs solar energy through its south-facing, translucent surface. This heat is stored and retained through a thick earthen back wall and insulation materials, minimizing the temperature difference between day and night. This allows for the cultivation of vegetables, flowers, and other crops in winter with minimal or no heating. A solar greenhouse primarily consists of earthen walls and a steel frame. The earthen walls primarily serve as heat storage, insulation, and support, 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. They also serve as the back wall supporting the greenhouse framework.

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

[0004] The existing soil heat storage solar greenhouse has gradually exposed its shortcomings during use, mainly in the following aspects: First, the applicability of metal frames is low. Specifically, due to the significant climate differences between the north and south of my country, the thickness of the solar greenhouse walls needs to be designed according to local conditions. For example, 3-meter-thick earth walls are required in extremely cold areas to enhance heat storage and insulation, while only 1.5 meters is needed in mild areas to meet the needs. Existing metal frame structures mostly use welding technology to make frames of fixed thickness. The thickness of the wall formed after filling with soil cannot be adjusted, resulting in metal frames of the same specifications being difficult to adapt to the insulation requirements of different climate zones, thereby reducing the applicability of the metal frame.

[0005] Second, the soil filling process is cumbersome. Specifically, the height of the metal frame structure is usually 4 meters. Due to the high height of the metal frame, the operation is extremely cumbersome when using large equipment to fill the soil.

[0006] Third, the welding and assembly process is complicated. Specifically, during the installation of the metal frame, the metal pipes need to be assembled and welded one by one at the construction site. Therefore, the assembly process is tedious and complicated, resulting in a long construction period.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0008] In response to the shortcomings of the prior art, the present invention aims to provide an assembled earth-heat-storing solar greenhouse that can adjust the thickness of its metal frame structure according to the climatic conditions of the area of ​​use, thereby achieving the function of adaptively adjusting the thickness of the earth wall and improving the applicability of the metal frame. The upper part of the metal frame structure of the greenhouse adopts a reversible design. The overall structure height can be lowered in the early stage of filling the soil. After the soil in the low-lying area is filled, the upper part of the frame is flipped back to its original position. Only the high-lying area needs to be supplemented and filled later, which simplifies the soil filling process. The metal frame structure of the solar greenhouse adopts a modular and detachable design, and the assembly process is simple.

[0009] In order to solve the above problems, the present invention provides the following technical solutions: The cam is connected to the support frame by a hinge connection, and the hinge parts are connected in an orderly manner, and the camshafts are connected in an orderly manner to the support frame by an arc connection, and the camshafts are connected in an orderly manner to the support frame by an arc connection.

[0010] As an optimized solution, a plurality of slide grooves are provided on the top of the support base, and a sliding plate is provided in the slide groove for horizontal sliding. One end of the sliding plate extends to the outside of the support base and is fixedly connected to the support plate.

[0011] As an optimized solution, the bottoms of the supporting plate and the sliding plate are both provided with threaded legs threadedly connected thereto, and the bottom of the sliding plate is provided with a plurality of mounting threaded holes.

[0012] As an optimized solution, a positioning bolt threadedly connected to the top of the sliding plate is provided, and a plurality of positioning threaded holes are provided at the bottom of the sliding groove.

[0013] As an optimized solution, the first hinge plate is hinged to the second hinge plate by means of bolts and nuts, and a plurality of adjustment holes are provided at the end of the second hinge plate.

[0014] As an optimized solution, the positioning plate is fixedly connected to the fixing plate by bolts and nuts, and a plurality of positioning holes are provided through the end of the fixing plate.

[0015] As an optimized solution, the two adjacent support plates and the two adjacent rotating plates are detachably connected by bolts and nuts.

[0016] As an optimized solution, the steel frame is detachably connected to the rotating plate via bolts and nuts.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When adjusting the thickness of the metal frame, drag the support plates on both sides of the support base to match their spacing with the required earth wall thickness, screw the positioning bolts into the corresponding positioning threaded holes and limit the sliding plate, select the adjustment holes at the appropriate position to hinge the second hinge plate on the support plate with the first hinge plate through bolts and nuts, select the installation threaded holes at the appropriate position to install the threaded legs at the bottom of the sliding plate, and when assembling the large metal frame, place several metal frames with adjusted low-level thickness into the concrete foundation and use bolts and nuts to connect the two adjacent support plates. Several metal frames are connected in sequence to form a large metal frame, and then steel mesh and geotextile are laid on the low-level inner wall of the large metal frame. The staff Fill the low area of ​​the metal frame with soil. After the soil in the low area is filled, rotate the rotating plate upwards and select the positioning holes at the appropriate positions to fix the positioning plate and the fixed plate with bolts and nuts. Select the adjustment holes at the appropriate positions to hinge the second hinge plate and the first hinge plate on the rotating plate with bolts and nuts. Then, use bolts and nuts to connect the two adjacent rotating plates. Then, lay the steel mesh and geotextile on the high inner wall of the large metal frame.

After the soil in the low area is filled, the upper part of the frame is flipped back to its original position. Only the high area needs to be supplemented and filled later, which simplifies the soil filling process. 3. The compressive strength of the support plate and the rotating plate can be enhanced by the hinged first and second hinged plates and the fixedly connected positioning plate and fixed 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 solar greenhouse. 4.

[0030] The working principle of this device is: When adjusting the thickness of the metal frame 2, drag the support plates 8 on both sides of the support base 11 so that their spacing matches 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 adjustment hole 12 at the appropriate position to hinge the second hinge plate 13 on the support plate 6 with the first hinge plate 16 through bolts and nuts, select the installation threaded holes 18 at the appropriate position to install the threaded support legs 9 at the bottom of the sliding plate 7, and when assembling the large metal skeleton, put several metal frames 2 with adjusted low-level thickness into the concrete foundation 1 and use bolts and nuts to connect the two adjacent support plates 6. Several metal frames 2 are connected in sequence to form a large metal skeleton, and then steel mesh and geotextile are laid on the low-level inner wall of the enclosed large metal skeleton.
