[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] See also Figures 1 to 5 The double-layer solar greenhouse provided by the present invention is now described. The double-layer solar greenhouse comprises a wall 1 and a double-layer frame. The wall 1 comprises, arranged from the inside outward, a soil layer, a fixed support 8, and an outer panel 11. The outer side of the outer panel 11 is provided with a rainproof film 12. The double-layer frame comprises an inner frame 3 and an outer frame 2 spaced apart longitudinally. The inner frame 3 is covered with an insulation blanket, and the outer frame 2 is covered with a transparent film.

[0026] Compared with the prior art, the double-layer solar greenhouse provided by the present invention thins the traditional wall 1, and adds a fixed bracket 8 and an outer plate 11 to the outer side of the thinned wall 1. The lower end of the fixed bracket 8 is fixed below the ground to achieve the main supporting function, improve the stability of the solar greenhouse, and improve the greenhouse's resistance to wind, rain and other disasters; the outer plate 11 is located on the outside to protect the fixed bracket 8 while preventing rain and water; the rainproof membrane 12 is covered on the outside of the outer plate 11 to further achieve a waterproof effect; the arch structure of the double-layer frame realizes the separate laying of the thermal insulation blanket and the transparent membrane, and the thermal insulation blanket is arranged on the inner frame 3 and protected by the transparent membrane on the outside, avoiding the problem that the thermal insulation blanket cannot be rolled up when it is wet and the thermal insulation performance is reduced, thereby improving the thermal insulation performance.

[0027] In addition, retaining the soil layer can achieve the insulation effect of the soil wall 7 structure on the temperature in the greenhouse and increase the stability of the wall 1.

[0028] Specifically, a space is set between the thinned soil layer and the outer plate 11 to form an insulation cavity between the soil layer and the outer plate 11. The fixed bracket 8 is located in the insulation cavity and is a skeleton structure. The fixed bracket 8 is located between the soil layer and the outer plate 11, and the lower end of the fixed bracket 8 is buried in an underground ring beam below the ground surface. The fixed bracket 8 is a steel frame, and the fixed bracket 8 includes a plurality of vertical rack rods and a plurality of horizontal rack rods. The vertical rack rods and the horizontal rack rods are welded and fixed to form the fixed bracket 8 body. The fixed bracket 8 body has a large range of space. The space is a closed space filled with air, which can reduce the transfer and loss of heat and achieve a thermal insulation effect.

[0029] The left and right sides of the heat preservation chamber are also wrapped and limited by the outer plate 11.

[0030] An insulation layer is laid between the fixed bracket 8 and the outer panel 11. The outer panel 11 presses the insulation layer against the outer side of the fixed bracket 8. One side of the fixed bracket 8 is firmly fixed to the back side of the earth wall 7. The other side of the fixed bracket 8 is covered with an insulation layer. This insulation layer is a rubber-plastic layer 9, made of a rubber-plastic insulation material. The insulation layer is fixed to and covers the fixed bracket 8. The outer panel 11 is installed on the other side of the insulation layer, pressing the insulation layer against the fixed bracket 8 and further ensuring the thermal insulation performance of the insulation cavity.

[0031] The outer plate 11 is an iron plate, a steel plate or a reinforced concrete casting plate. When the outer plate 11 is an iron plate or a steel plate, the outer plate 11 and the fixing bracket 8 are fixed with structures such as bolts, steel wires, and steel bars, and the thermal insulation layer is fixed between the outer plate 11 and the fixing bracket 8.

[0032] The insulation layer also includes a cotton felt layer 10, located on the side of the rubber-plastic layer 9 near the outer panel 11. The inner and outer sides of the cotton felt layer 10 are respectively attached to the outer panel 11 and the rubber-plastic layer 9. The cotton felt layer 10 is secured to the outer side of the rubber-plastic layer 9 and attached to the outer panel 11, thereby improving the insulation between the outer panel 11 and the insulation cavity. The cotton felt layer 10 and the rubber-plastic layer 9 can be secured using nails or bolts.

[0033] The upper end of the wall 1 is covered with a top plate 5, and the fixed end of the double-layer frame is provided with a connecting plate, which is attached to the upper end of the top plate 5. The top plate 5 is a reinforced concrete slab, which is placed horizontally on the top of the wall 1 and covers the entire wall 1; the top plate 5 is used to support the double-layer frame.

[0034] A plurality of longitudinal holes are provided on the top plate 5, and the fixed ends of the double-layer frame are fixed to the top plate 5 by means of the holes. The top plate 5 can be a cast ring beam.

[0035] Furthermore, the upper end of the fixed bracket 8 is provided with an upwardly extending connecting rib 6, which passes through the top plate 5 and is connected to the connecting plate. The connecting rib 6 has a longitudinal through-hole, and the lower end of the connecting rib 6 extends to the fixed bracket 8 and is fixedly connected to the upper end of the fixed bracket 8. The upper end of the connecting rib 6 extends above the top plate 5.

[0036] During construction, the earth wall 7 is first thinned. Then, the fixing brackets 8, insulation layer, and outer panels 11 are installed. Rainproof membrane 12 is laid on the outer panels 11. After the wall 1 is constructed, connecting ribs 6 are installed at the upper ends of the fixing brackets 8, extending upward. Next, the top panel 5 is installed. The top panel 5 is inserted from top to bottom onto the connecting ribs 6, with the upper ends of the connecting ribs 6 protruding from the holes in the top panel 5. The upper ends of the connecting ribs 6 are connected to the fixed ends of the double-layer frame.

[0037] The inner and outer frames 3 and 2 of the double-layer frame are fixed at the end closest to the wall 1, with their ends integrated. The fixed ends of the inner and outer frames 3 and 2 are fixed as a single unit to the upper end of the top plate 5 and are fixedly connected to connecting ribs 6. A fixed plate 4 is connected to the fixed ends of the inner and outer frames 3 and 2, which engage with the connecting ribs 6. The fixed plate 4 and the top plate 5 are bolted or cast-bonded.

[0038] In some possible embodiments, see Figure 4 and Figure 5 The fixed bracket 8 includes a main bracket and an auxiliary bracket 13. There is a partition 14 and an insulation structure between the auxiliary bracket 13 and the main bracket.

[0039] The main support is located near the earth wall 7, and the auxiliary support 13 is spaced apart from the main support with a partition 14 between them. Insulation structures are provided on both sides of the partition 14. The insulation structure is identical to the structure of the insulation layer, namely a rubber-plastic layer 9 and a cotton felt layer 10. This creates two support structures and an insulation cavity within the wall 1, strengthening the wall 1 while improving the insulation effect.

[0040] The outer side of the auxiliary bracket 13 is installed with a heat-insulating layer and an outer plate 11 , and the outer side of the outer plate 11 is paved with a rainproof membrane 12 .

[0041] In some possible embodiments, see Figures 2 to 5 A reel is provided at the top of the inner skeleton 3, and the thermal insulation quilt can be wound on the reel, and the end of the reel is connected to a driving motor.

[0042] The reel is located above the top of the inner frame 3 and is used to reel in the thermal insulation quilt. The reel can be reeled in or out by adjusting the forward or reverse rotation of the driving motor.

[0043] Correspondingly, an outer frame 2 is provided above the inner frame 3 , and space for arranging a thermal insulation quilt is reserved between the outer frame 2 and the inner frame 3 .

[0044] The exoskeleton 2 includes multiple poles and multiple traction ropes. The multiple traction ropes are alternately arranged with the multiple poles, and the traction ropes are located on the center line of two adjacent poles. The traction ropes cover the outside of the transparent film and press the transparent film on the upper end of the pole.

[0045] The arched poles are spaced apart, with a traction rope installed between each pair of adjacent poles. The traction rope and the poles are coplanar. The traction rope is positioned above the transparent film, pressing the film against the poles to facilitate opening and closing of the film while also improving its stability.

[0046] A crossbar for adjusting the direction of the traction rope is provided at the top of the exoskeleton 2. The traction rope and crossbar are not shown.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
