Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, specifically relating to a novel nested temperature-controlled greenhouse. Background Technology

[0002] Agricultural greenhouses are protective structures widely used in modern facility agriculture, mainly composed of a supporting frame and light-transmitting covering materials. Their core function is to create a suitable microclimate environment to enable off-season cultivation of crops and protection against severe weather. Traditional greenhouses generally adopt a single-layer structure design, which has advantages such as low cost and simple construction. However, in actual use, especially in areas with frequent snowfall in winter, this structure has revealed obvious functional defects.

[0003] When single-layer greenhouses encounter continuous snowfall, the snow on the roof is difficult to slide off naturally and often requires manual clearing. This is not only inefficient but also poses safety hazards for working at heights. More seriously, when the snow depth exceeds the greenhouse's load-bearing limit, it can easily cause the roof to collapse, resulting in damage to crops and facilities inside the greenhouse and causing significant economic losses to growers. In addition, snow cover can significantly reduce the light intensity inside the greenhouse, affecting the normal photosynthesis of crops and leading to reduced yields or even crop failure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in the figure, a novel nested temperature-controlled greenhouse includes an outer arched greenhouse and an inner arched greenhouse located inside the outer arched greenhouse. The outer arched greenhouse includes a first frame 1, the top of which has a pointed shape to facilitate the rapid flow of rainwater. The first frame 1 is made of high-strength galvanized steel pipe and its surface is coated with a low-friction coating, such as Teflon coating, to prevent snow accumulation on the first frame 1. The outside of the first frame 1 is covered with a rollable double-layer insulation film 2. This double-layer insulation film 2 can be rolled up using an electric film roller, a manual film roller, etc., to facilitate rolling up or unrolling operations under different environmental conditions. This rolling structure and principle are conventional designs in existing technology and will not be elaborated further here.

[0025] A base 7 is installed at the upper part of the interior of the first frame 1. A spring 9 is connected to the lower end of the base 7, and the lower end of the spring 9 is connected to the first frame 1. A vibrator 8 is installed on the upper surface of the base 7. Multiple upward and outward extending connecting rods 10 are connected to both sides of the base 7. A movable rod 11 is fixed to the end of the connecting rod 10. The movable rod 11 is arranged along the length of the outer arch. A vibrating plate 13 is fixed on the movable rod 11. The vibrating plate 13 can be made of a light-transmitting plastic plate, such as PC board, PP board, PVC board, etc. The length and width of 3 can be adapted to the size of the hollow area of ​​the first frame 1; the vibrating plate 13 is set in the hollow area of ​​the first frame 1, and in the natural state, the upper surface of the vibrating plate 13 is in contact with the lower surface of the double-layer insulation film 2. Specifically, when the snow is thick in winter, the vibrator 8 can be started. The vibrator 8 can drive the base plate, connecting rod 10 and movable rod 11 to vibrate, and finally transmit the power to the vibrating plate 13. Since the vibrating plate 13 is in direct contact with the double-layer insulation film 2, the snow can be shaken off quickly.

[0026] Multiple limiting rings 12 are installed inside the first frame 1. The movable rod 11 passes through the limiting ring 12. The diameter of the movable rod 11 is smaller than the inner diameter of the limiting ring 12, which allows the movable rod 11 to move radially within the limiting ring 12. The limiting ring 12 is mainly set to play a safety protection role and prevent the movable rod 11 from falling and causing damage to the inner arch below.

[0027] The inner arched greenhouse includes a second frame 3 with an arched dome. The surface of the second frame 3 is covered with a light-transmitting film 4. A rollable shade net 6 is installed outside the light-transmitting film 4. The arched dome structure allows for uniform light distribution. The light-transmitting film 4 is a PO film with high light transmittance to improve light transmittance. The external shade net 6 can be flexibly rolled up according to environmental conditions to adapt to different seasons or crop light requirements. The rolling structure and principle of the shade net 6 are conventional in existing technology and will not be elaborated further. The combination of the light-transmitting film 4 and the shade net 6 forms a double-layer protection, providing shade and cooling in summer and reducing heat loss in winter, thus improving the greenhouse's year-round adaptability.

[0028] The second frame 3 has multiple spray pipes 5 installed inside. Below the spray pipes 5 and at equal intervals along their length, multiple nozzles are arranged, and the nozzles are connected to the inside of the spray pipes 5. The spray pipes 5 are evenly distributed inside the second frame 3, which can realize irrigation without dead corners in the greenhouse. The spacing design of the nozzles ensures that the water mist coverage is uniform and meets the water requirements of the crops.

[0029] Electric roller shutter doors 15 are installed at both ends of the first frame 1. The electric roller shutter doors 15 can be opened and closed quickly, which facilitates the entry and exit of large agricultural machinery or personnel. At the same time, they work with the top ventilation openings 14 to form convection, enhance the efficiency of natural ventilation, and facilitate the regulation and control of temperature and humidity inside the greenhouse.

[0030] The double-layer heat insulation film 2 includes an inner layer of EVA heat insulation film 201 and an outer layer of PE reflective film 202. The EVA film blocks heat from escaping at night, and the PE reflective film 202 reflects excess sunlight during the day, thus reducing energy consumption.

[0031] The inner arched greenhouse is equipped with multiple temperature and humidity sensors arranged at various points inside the greenhouse. This allows for comprehensive monitoring of the temperature and humidity conditions inside the greenhouse, preventing localized environmental anomalies from affecting crop growth. It also provides accurate data support for automatic sprinkler and ventilation systems, enabling intelligent management.

[0032] The top of the outer arched shed is equipped with a ventilation opening 14, and the interior of the inner arched shed is equipped with a fan. The fan and the ventilation opening 14 work together to force out hot and humid air, prevent pests and diseases, avoid the accumulation of hot air on the roof, and form a circulating airflow in combination with the structure of the inner arched shed to reduce temperature stratification.

[0033] The inner arched greenhouse is also equipped with a light intensity sensor, which can monitor light data to ensure that crops receive the best light intensity. The outer arched greenhouse is also equipped with a rain and snow sensor to monitor the environmental conditions during rain and snow, and to determine whether snow removal or closing of the ventilation opening 14 is necessary based on the data to prevent extreme weather from damaging the greenhouse structure.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
