Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an aerogel inner insulation curtain for intelligent greenhouses. Background Technology

[0002] A smart greenhouse is a highly efficient agricultural facility that integrates modern agricultural technology, the Internet of Things (IoT), automated control, environmental monitoring and regulation, and other technologies. By accurately monitoring and automatically adjusting key environmental factors such as light, temperature, humidity, CO2 concentration, and soil moisture within the greenhouse, it creates a stable and suitable optimal environment for crop growth, thereby achieving high-yield, high-quality, and efficient crop cultivation while reducing reliance on manual labor and resource consumption.

[0003] When adjusting the light transmittance of intelligent greenhouses, in addition to laying shading nets or shading curtains on the outside of the greenhouse, they usually also lay inner shading curtains similar to curtains inside and adjust them through track motors. However, these inner shading curtains generally do not have a heat preservation effect, and due to gravity, they can only be laid around the walls and cannot be laid on the top of the greenhouse, leaving room for further improvement.

The ends of the two speed reducers away from the thermal insulation curtain frame are fixedly connected to a drive motor. Inside the thermal insulation curtain frame, at positions corresponding to the inner and outer sliding grooves, lifting screws are rotatably connected. Both ends of the four lifting screws are fixedly sleeved with synchronous gears. Inside the frame of the thermal insulation curtain frame, at positions corresponding to the speed reducers, two meshing linkage gears are provided.

[0017] This section will describe in detail the specific embodiments of the present utility model. Preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4This utility model provides an intelligent greenhouse aerogel inner insulation curtain, including an insulation curtain frame 1 and an aerogel insulation film 2. Insulating glass is fixedly connected to both sides of the aerogel insulation film 2 on the insulation curtain frame 1. The aerogel insulation film 2 is disposed inside the insulation curtain frame 1. Rotating shafts 10 are rotatably connected inside the upper and lower frames of the insulation curtain frame 1. Reducers 14 are fixedly connected to one diagonal corner of the insulation curtain frame 1. A coil spring resetter 12 is fixedly connected to the end of the rotating shaft 10 away from the reducer 14 inside the frame of the insulation curtain frame 1. The two rotating shafts 10 are located away from the reducer 14. One end of each device 14 is connected to the coil spring shaft at the center of the coil spring reset device 12 to ensure the winding reset of the aerogel insulation film 2. Both rotating shafts 10 are provided with winding sleeves 11 on their outer sides. Both ends of the aerogel insulation film 2 are wound and fixed on the outer side of the corresponding winding sleeves 11. The inner middle of the upper and lower frames of the insulation curtain frame 1 is provided with insulation film inlet and outlet strip holes corresponding to the winding sleeves 11. The two rotating shafts 10 are used to share and reduce the winding space requirement of the aerogel insulation film 2, improve the space utilization of the frame, and at the same time reduce the stress intensity of the aerogel insulation film 2 when the lifting lever 9 is pulled. Inner sliding grooves 3 are provided on one side of the inner wall at both ends of the thermal insulation curtain frame 1, and outer sliding grooves 4 are symmetrically provided on the side of the inner wall at both ends of the thermal insulation curtain frame 1 away from the inner sliding grooves 3. A first sliding block 7 is slidably connected inside each of the two inner sliding grooves 3, and a second sliding block 8 is slidably connected inside each of the two outer sliding grooves 4. Multiple lifting screws 5 pass through the corresponding first sliding block 7 and second sliding block 8 and are threadedly engaged with the first sliding block 7 and second sliding block 8. The two sides of the aerogel thermal insulation film 2 are respectively connected to the inner sliding grooves 3 and outer sliding grooves 4. Lifting levers 9 are provided at corresponding positions. The two ends of the two lifting levers 9 are fixedly connected to the two first slides 7 and the two second slides 8 respectively. Rotating sleeves are rotatably sleeved on the outer side of the two lifting levers 9. The lifting and lowering directions of the two lifting levers 9 are opposite. The aerogel insulation film 2 is wrapped around the two lifting levers 9 in a zigzag shape, so that the aerogel insulation film 2 changes from a single layer to a three-layer folded form as the two lifting levers 9 move. This not only allows for flexible adjustment of the shading rate, but also allows for adjustment of the insulation performance. Two reducers 14 are fixedly connected to drive motors 15 at their ends away from the insulation curtain frame 1. Inside the insulation curtain frame 1, lifting screws 5 are rotatably connected at positions corresponding to the inner slide groove 3 and the outer slide groove 4. Multiple lifting screws 5 pass through corresponding first slides 7 and second slides 8 and are threadedly engaged with the first slides 7 and second slides 8. Synchronous gears 6 are fixedly sleeved at both ends of the four lifting screws 5. Inside the frame of the insulation curtain frame 1, at positions corresponding to the reducers 14, two meshing linkage gears 13 are provided. Multiple linkage gears 13 are bevel gears. The output end of the reducer 14 and the end of the lifting screw 5 near the reducer 14 are fixedly connected to the corresponding linkage gears 13. Through the cooperation of the drive motor 15 and the reducer 14, the first slides 7 and second slides 8 on both sides are driven, which in turn drives the lifting lever 9 to perform synchronous reverse movement.

[0019] Working principle: In operation, the heat insulation curtain frame 1 and the synchronously reverse-moving lifting screw 5, together with the aerogel insulation film 2 zigzag-wrapped around the two lifting levers 9, can change the shape of the aerogel insulation film 2 from a single layer to a three-layer fold as the lifting levers 9 move. This not only allows for flexible adjustment of the shading rate but also the heat insulation performance. At the same time, by setting the foldable aerogel insulation film 2 inside the heat insulation curtain frame 1, it can be built into the glass curtain wall of the intelligent greenhouse, which not only reduces the internal space occupied by the greenhouse but also allows it to be directly installed on the top of the greenhouse, avoiding the shortcomings of existing internal shading curtains.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
