Description

Technical Field

[0001] The utility model belongs to the technical field of solar greenhouses, and in particular relates to a solar greenhouse with a flexible heat-insulating wall. Background Art

[0002] In the existing technology, the solar greenhouse, as an important part of modern facility agriculture, provides a relatively stable growth environment for plants by effectively utilizing solar energy. It is mainly composed of gables on both sides, a rear wall, a supporting frame and covering materials. The greenhouse mainly absorbs solar energy through the rear wall to achieve heat storage and release, thereby maintaining a certain temperature level indoors to meet the growth needs of vegetables and other crops.

[0003] However, traditional solar greenhouse walls are usually made of hard materials such as concrete and bricks. These materials are not only expensive and have a long construction period, but also have many shortcomings in terms of thermal insulation performance and structural flexibility. Therefore, it is necessary to find new heat storage and insulation materials to replace the existing gables or rear walls made of clay bricks or earth blocks to shorten the construction period and save costs.

[0004] A Chinese patent with application number CN212464246U discloses a solar greenhouse with thermal insulation materials combined, which includes a rear wall and a greenhouse ceiling, as well as gables on both sides of the rear wall, wherein the rear wall and the gables on both sides include: a wall body, wherein the wall body has a containing space, wherein the containing space is filled with lightweight thermal insulation materials; the wall body includes: a thermal insulation composite wall panel, wherein the core layer of the thermal insulation composite wall panel has a plurality of honeycomb pores for heat insulation and heat preservation, and cooperates with the lightweight thermal insulation materials to perform ecological regulation on the humidity in the greenhouse; a protective cloth layer, which is arranged on the side of the wall body facing the greenhouse ceiling, and closely cooperates with the thermal insulation composite wall panel to form the containing space; the rear wall and the gables on both sides of the solar greenhouse are filled with lightweight thermal insulation materials in the containing space formed by the combination of the thermal insulation composite wall panel and the protective cloth layer, thereby achieving a good thermal insulation effect while ensuring strength and reducing weight, and is convenient to install, has a short construction period, and is convenient to transport.

[0005] However, the wall in this patent is composed of thermal insulation composite wall panels and filled lightweight thermal insulation materials, which makes its overall weight light and its weighing capacity weak. It is easy to be damaged in windy weather. At the same time, the wall in this patent cannot be reused after it is no longer needed to be dismantled, which easily causes waste. Utility Model Content

[0019] The utility model adopts the above technical scheme, with ingenious conception and reasonable structure. The greenhouse frame of the solar greenhouse is made of hot-dip galvanized strip pipe fixed connection. Compared with the earth wall of the traditional solar greenhouse, the greenhouse frame is easy to disassemble and assemble, with high land utilization rate, movable, recyclable and reusable, and can meet the requirements of environmentally friendly construction of solar greenhouses. The greenhouse frame is provided with an entry door for small agricultural machinery to enter, which is convenient for mechanized operation in the solar greenhouse. At the same time, the lower end of the greenhouse frame is fixed to the ground soil layer by a plurality of detachable spiral piles.

[0034] The access door 22 is sized to allow passage of small agricultural machinery.

[0035] The rear wall frame 4 is also made of a plurality of hot-dip galvanized strip pipes fixedly connected.

[0036] The ceiling frame 3 is also made of a plurality of hot-dip galvanized strip pipes fixedly connected.

[0037] The shape of the ceiling frame 3 matches the shapes of the upper end surfaces of the first gable frame 1 and the second gable frame 2 .

[0038] The lower end surfaces of the first gable frame 1, the second gable frame 2, and the rear wall frame 4 are respectively provided with a plurality of spiral ground piles 21 in parallel and at intervals, and the plurality of spiral ground piles 21 are simultaneously detachably connected to the lower end surfaces of the first gable frame 1, the second gable frame 2, and the rear wall frame 4.

[0039] like Figure 7 As shown, a pipe body 210 is provided at the lower ends of the first gable frame 1 , the second gable frame 2 , and the rear wall frame 4 at positions corresponding to the spiral piles 21 , and a connecting sleeve 213 is fixedly installed on the outer surface of the pipe body 210 .

[0040] A first through hole is formed at the center of the lower end surface of the connecting sleeve 213 .

[0041] A second through hole is vertically opened on an outer wall of the connecting sleeve 213 , and the second through hole penetrates the tube body 210 to the other outer wall of the connecting sleeve 213 .

[0043] A third through hole is formed on the outer surface of the upper end of the central shaft 212 at a position corresponding to the second through hole.

[0044] The upper end of the central shaft 212 passes through the first through hole of the connecting sleeve 213 and extends into the interior of the tube body 210 .

[0045] A plug bolt 214 is inserted into the second through hole of the connecting sleeve 213 , and the plug bolt 214 simultaneously passes through the third through hole of the central shaft 212 and the outer wall of the other side of the connecting sleeve 213 and is threadedly connected with a locking bolt 218 .
