Technical Field
[0001] This utility model relates to the field of greenhouse technology, specifically to a greenhouse with a double-layer heat-insulating film structure. Background Technology
[0002] In modern agricultural production, greenhouses serve as important facilities, creating a suitable environment for crop growth, effectively overcoming seasonal and climatic limitations, and improving crop yield and quality. Among these, heat preservation performance is one of the key indicators for evaluating the quality of greenhouses, directly affecting the temperature stability inside the greenhouse and the growth cycle of crops.
[0003] A search revealed that patent publication number CN207427969U discloses a double-layer dehumidifying and heat-insulating greenhouse, comprising a gable wall, a rear wall, an inner frame, a rear heat-insulating low wall, an outer frame, and a front heat-insulating low wall. The gable wall is located on both sides of the rear wall. The first end of the inner frame and the lower end of the rear heat-insulating low wall are fixedly connected to the upper end of the rear wall. The rear heat-insulating low wall has an upper ventilation opening to exhaust humid air. The outer and inner frames are covered with a plastic film, and the gap between the inner and outer frames forms an air layer to insulate the greenhouse. The second ends of the inner and outer frames are fixedly connected to the upper end of the front heat-insulating low wall, and the lower end of the front heat-insulating low wall is fixedly connected to the ground. The front heat-insulating low wall has a lower ventilation opening to exhaust humid air from the air layer.
[0004] While existing greenhouses with double-layer insulation film structures have improved insulation performance, they suffer from inconvenience in laying and retracting the inner insulation film during actual use. The existing inner insulation film retraction devices are complex in structure and cumbersome to operate, making it difficult to achieve rapid laying and rolling. Furthermore, large gaps easily appear between the insulation film and the frame during laying, affecting the insulation effect. Therefore, a greenhouse with a double-layer insulation film structure is designed. Utility Model Content
[0005] In view of the defects or deficiencies of existing greenhouses, the purpose of this utility model is to provide a greenhouse with a double-layer insulation film structure, which can flexibly control the covering state of the second insulation film according to actual needs and weather changes, and avoids the phenomenon of large gaps between the second insulation film and the second mounting frame.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0007] This utility model provides a greenhouse with a double-layer heat-insulating film structure, including a ground beam. A supporting side plate is installed on one side of the top of the ground beam. A first mounting frame and a second mounting frame are installed between the top of the ground beam and the outer wall of one side of the supporting side plate, with the second mounting frame located inside the first mounting frame. A first heat-insulating film is laid on the top of the first mounting frame. A heat-insulating film retraction assembly for retracting and extending the second heat-insulating film is provided above the second mounting frame. The heat-insulating film retraction assembly is set on an arc-shaped pneumatic slide for moving the heat-insulating film retraction assembly in a certain direction. A fixing assembly for fixing and clamping one end of the second heat-insulating film is provided on the outer wall of one side of the supporting side plate.
[0008] Preferably, the arc-shaped pneumatic slide is disposed between one outer wall of the support side plate and the top of the ground beam, and the arc-shaped pneumatic slide is located at the front and rear ends of the second mounting frame.
[0009] Preferably, the fixing component is located between the first mounting frame and the second mounting frame. The fixing component is composed of a pneumatic telescopic rod, a third mounting plate and a fixing block. The third mounting plate is installed on the upper part of the outer wall of one side of the support side plate.
[0010] Preferably, a pneumatic telescopic rod is installed at the top of the third mounting plate. The telescopic end of the pneumatic telescopic rod passes through the surface of the third mounting plate and is connected to the fixing block, and the other end of the fixing block is located in the groove on the top of the second mounting frame.
[0011] Preferably, the heat-insulating film take-up and untake-down assembly is provided with a roller body, on which a second heat-insulating film is wound. The connecting shafts on both ends of the roller body pass through the bearings on the outer walls of the two first mounting plates respectively, and the other end of one of the connecting shafts is connected to a geared motor through a coupling. The geared motor is installed on the top of a support block, and the support block is set on one side of the outer wall of one of the first mounting plates.
[0012] Preferably, a second mounting plate is provided below the first mounting plate, and guide posts are installed on both sides of the upper surface of the second mounting plate. The other end of the guide post passes through a through hole on the surface of the protrusion and is connected to the limiting plate. The outer diameter of the guide post is equal to the diameter of the through hole, and the guide post and the limiting plate are connected by a threaded engagement.
[0013] Preferably, a spring is sleeved on the outer side of the guide post, and the spring is located between the limiting plate and the protrusion. The protrusion is disposed on the outer side of both sides of the first mounting plate, and the second mounting plate is mounted on the top of the arc-shaped pneumatic slide.
[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0015] 1. In this utility model, through a series of coordinated structural arrangements, when workers need to lay the second insulation film on the top of the second mounting frame or roll up the second insulation film on the second mounting frame, the workers activate the arc-shaped pneumatic slide and the reduction motor. The reduction motor drives the roller to rotate and unwind or rewind the second insulation film. When the arc-shaped pneumatic slide is activated, it drives the insulation film unwinding and rewinding assembly to move along the top of the second mounting frame. The insulation film unwinding and rewinding assembly can lay the second insulation film on the top of the second mounting frame or roll up the second insulation film on the second mounting frame when unwinding or rewinding the second insulation film. Thus, this utility model can flexibly control the covering state of the second insulation film according to actual needs and weather changes. When it is necessary to enhance the insulation effect, the second insulation film can be quickly laid on the top of the second mounting frame. When the weather warms up or when working inside the greenhouse, it can be easily rolled up. The operation is simple and efficient, saving manpower and time costs.
[0016] 2. In this utility model, through a series of coordinated structural arrangements, as the arc-shaped pneumatic slide table drives the insulation film take-up and put-down assembly to move along the top of the second mounting frame, the roller body, with the help of the spring, guide rod and other structures, can adaptively move in a certain direction by means of the automatic adjustment function generated by the spring compression and rebound, ensuring that the second insulation film is always in close contact with the top of the second mounting frame, effectively avoiding the phenomenon of large gaps between the second insulation film and the second mounting frame, preventing heat loss due to gaps, and improving the insulation effect.

[0035] like Figure 1-5As shown, a greenhouse with a double-layer insulation film structure includes a ground beam 400. A supporting side plate 300 is installed on one side of the top of the ground beam 400. A first mounting frame 200 and a second mounting frame 700 are installed between the top of the ground beam 400 and the outer wall of one side of the supporting side plate 300, and the second mounting frame 700 is located inside the first mounting frame 200. A first insulation film 100 is laid on the top of the first mounting frame 200. An insulation film retraction assembly 500 for retracting and extending the second insulation film is provided above the second mounting frame 700. The insulation film retraction assembly 500 is mounted on an arc-shaped pneumatic slide 600 for moving the insulation film retraction assembly 500 in a certain direction. A fixing assembly 800 for fixing and clamping one end of the second insulation film is provided on the outer wall of one side of the supporting side plate 300.
[0036] The arc-shaped pneumatic slide 600 is located between one outer wall of the support side plate 300 and the top of the ground beam 400, and the arc-shaped pneumatic slide 600 is located at the front and rear ends of the second mounting frame 700.
[0037] The fixing component 800 is located between the first mounting frame 200 and the second mounting frame 700. The fixing component 800 is composed of a pneumatic telescopic rod 810, a third mounting plate 820 and a fixing block 830. The third mounting plate 820 is installed on the upper part of the outer wall of one side of the support side plate 300.
[0038] A pneumatic telescopic rod 810 is installed at the top of the third mounting plate 820. The telescopic end of the pneumatic telescopic rod 810 passes through the surface of the third mounting plate 820 and is connected to the fixing block 830. The other end of the fixing block 830 is located in the groove on the top of the second mounting frame 700. When the pneumatic telescopic rod 810 is started, it will drive the fixing block 830 to move linearly in a certain direction. The linear movement of the fixing block 830 in a certain direction can fix one end of the second insulation film in the groove.
[0039] The heat insulation film unwinding assembly 500 is equipped with a roller body 510, on which a second heat insulation film is wound. The connecting shafts on both ends of the roller body 510 pass through bearings on the outer walls of the two first mounting plates 550 respectively, and the other end of one of the connecting shafts is connected to a geared motor 560 through a coupling. The geared motor 560 is mounted on the top of a support block 570, and the support block 570 is located on one side of the outer wall of one of the first mounting plates 550. When the geared motor 560 starts, it will drive the roller body 510 to rotate forward or backward. When the roller body 510 rotates forward or backward, it will cause the second heat insulation film wound on the roller body 510 to unwind or rewind.
[0040] A second mounting plate 580 is provided below the first mounting plate 550. Guide posts 520 are installed on both sides of the upper surface of the second mounting plate 580. The other end of the guide post 520 passes through the through hole on the surface of the protrusion 590 and is connected to the limiting plate 530. The outer diameter of the guide post 520 is equal to the diameter of the through hole. Because the outer diameter of the guide post 520 is equal to the diameter of the through hole, it can limit and guide the roller 510 during the displacement process of the spring 540 compression and rebound. The guide post 520 and the limiting plate 530 are connected by a threaded engagement. Because the guide post 520 and the limiting plate 530 are connected by a threaded engagement, the spring 540 can be disassembled and replaced.
[0041] A spring 540 is sleeved on the outer side of the outer wall of the guide post 520, and the spring 540 is located between the limiting plate 530 and the protrusion 590. The protrusion 590 is set on the outer walls of both sides of the first mounting plate 550, and the second mounting plate 580 is mounted on the top of the arc-shaped pneumatic slide 600.
[0042] Working Principle: In use, when an external power source is connected, and the operator needs to lay the second insulation film on the top of the second mounting frame 700 or roll up the second insulation film on the second mounting frame 700, the operator activates the arc-shaped pneumatic slide 600 and the reduction motor 560. The reduction motor 560 drives the roller 510 to rotate and unwind or wind up the second insulation film. When the arc-shaped pneumatic slide 600 is activated, it drives the insulation film unwinding and winding assembly 500 to move along the top of the second mounting frame 700. The insulation film unwinding and winding assembly 500 can lay the second insulation film on the top of the second mounting frame 700 or wind up the second insulation film on the second mounting frame 700, thus allowing the invention to be used according to actual needs. The second insulation film can be flexibly controlled according to weather changes. When enhanced insulation is needed, it can be quickly laid on top of the second mounting frame 700. When the weather warms up or when working inside the greenhouse, it can be easily rolled up. The operation is simple and efficient, saving manpower and time costs. As the arc-shaped pneumatic slide 600 drives the insulation film unfolding and retracting component 500 to move along the top of the second mounting frame 700, the roller 510 can move adaptively in a certain direction with the help of the spring 540, guide rod and other structures, and the automatic adjustment function generated by the compression and rebound of the spring 540. This ensures that the second insulation film is always in close contact with the top of the second mounting frame 700, effectively avoiding large gaps between the second insulation film and the second mounting frame 700, preventing heat loss due to gaps and improving the insulation effect.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
