Description

Technical Field

[0002] Winters in northern regions are extremely cold, with temperatures generally ranging from -10 to 30 degrees Celsius. Currently, most of the greenhouses widely used are single-layer membrane structures. Although they are simple in structure, easy to construct, and inexpensive, they have poor insulation capabilities, especially in terms of wind and snow resistance. The single-layer membrane structure means that the temperature inside the greenhouse is usually only 3 to 5 degrees Celsius at night. In extreme weather, the temperature may drop to near freezing, seriously affecting crop growth. Due to poor insulation performance, the temperature loss at night is serious, making it difficult to maintain a temperature suitable for crop growth inside the greenhouse. This type of greenhouse is suitable for use in warmer areas.

DETAILED DESCRIPTION

[0020] Example 1 like Figures 1 to 14 As shown, the solar greenhouse structure based on the self-insulating material includes a sun room 1, a greenhouse 2 is arranged inside the sun room 1, a photovoltaic power generation system 3 is arranged on the sun room 1, and a ventilation system 4 is arranged between the greenhouse 2 and the sun room 1; The front wall 206, the rear wall 210 and the side wall 201 of the greenhouse 2 are formed by layered casting of a composite wall body with a concrete core wall 15 inside and insulation walls 18 inside and outside. A double-layer frame is provided on the top of the greenhouse 2. The upper frame 207 is covered with a film 202. The film 202 is tightened and fixed on the wall body. A quilt rolling machine 209 and a rolled quilt are provided on the lower frame 208. The quilt covers the lower frame 208. A heat storage device is provided on the rear wall 210 of the greenhouse 2 which is exposed to direct sunlight.

[0021] The walls of the greenhouse adopt a composite wall design with a concrete core wall on the inside and an insulation wall on the outside. This structure can effectively improve the thermal insulation performance of the greenhouse and reduce heat loss, especially in cold seasons, which can significantly reduce heating costs.

[0022] The photovoltaic power generation system installed on the sunroom can not only use solar energy to generate electricity to meet the greenhouse's own electricity needs, such as lighting, irrigation, etc., but also sell excess electricity to the power grid, achieving energy conservation and emission reduction while bringing economic benefits.

[0023] The ventilation system between the greenhouse and the sun room helps to regulate the temperature and humidity in the greenhouse and create a microclimate environment suitable for plant growth. By properly setting the position and size of the air inlet and outlet, air circulation can be effectively promoted to avoid the occurrence of pests and diseases.

[0024] The double-layer frame design on the top of the greenhouse, coupled with the outer film and the inner rollable quilt, creates a good heat preservation and sunshade effect. In summer, the quilt can be rolled up to increase ventilation and light transmission; in winter, the quilt can be put down to enhance heat preservation, flexibly responding to the needs of different seasons.

[0025] A heat storage device is installed on the back wall that is exposed to direct sunlight. It can absorb and store solar radiation energy during the day, and release heat at night or on cloudy days, further improving the temperature conditions in the greenhouse and ensuring normal growth of crops.

[0026] Preferably, a plurality of vents are provided on the rear wall 210 of the greenhouse 2, and the vents are connected to the outside through pipes passing through the sun room 1; The vent is provided with a switch window, a blower is provided in the duct, and an air intake grille is provided where the duct is connected to the outside world; The vents are divided into air inlets and air outlets. The blower on the air inlet faces inward, while the blower on the air outlet faces outward.

[0027] Blowers with different wind directions can drive the air circulation in the greenhouse 2, thereby adjusting the temperature and humidity in the greenhouse.

[0028] There are multiple vents on the back wall of the greenhouse. These vents are not only directly connected to the inside of the greenhouse, but also connected to the outside world through pipes, forming a complete air circulation system.

[0029] The distinction between the air inlet and the air outlet makes the air flow direction clear, which is conducive to the formation of effective air convection.

[0030] Each vent is equipped with a blower. The blower at the air inlet faces inward and is responsible for introducing fresh air from the outside into the greenhouse; while the blower at the air outlet faces outward and is used to exhaust the air in the greenhouse.

[0031] The blower can adjust the air volume as needed to adapt to different climatic conditions and crop growth stages.

[0032] An air intake grille is set at the point where the pipeline is connected to the outside world, which can not only block large particles of impurities from entering the greenhouse, but also prevent small animals from entering, thus ensuring the safety of the greenhouse environment.

[0033] When the temperature in the greenhouse is too high, you can start the blower at the air outlet to accelerate the discharge of indoor hot air, and at the same time turn on the blower at the air inlet to introduce cooler fresh air from the outside to achieve a cooling effect. If the humidity in the greenhouse is too high, you can also reduce the humidity by increasing air circulation. By properly controlling the working state of the air inlet and outlet blowers, you can effectively remove excess water vapor and maintain a suitable relative humidity. For some crops that require a higher CO2 concentration, proper air exchange can also replenish CO2 in the greenhouse, promote photosynthesis, and increase yields.

[0034] Preferably, a plurality of sleeves 212 are provided on both sides of the film 202, and a sliding side rope 204 is provided inside the sleeve 212, and the side rope 204 protrudes outwards between two adjacent sleeves 212 to form a ring; A plurality of fixing rods 211 are fixedly disposed at the top edge of the side wall 201 . The side rope 204 passes through the plurality of fixing rods 211 in sequence. One end of the side rope 204 is fixed to the first fixing rod 211 , and the other end is fixed to the last fixing rod 211 after being tightened.

[0035] There are multiple sleeves 212 with curled edges on both sides of the film 202, with a gap between two adjacent sleeves 212. The side rope 204 is passed through the sleeves 212 and protrudes outward to form a ring at the gap. During installation, one end of the side rope 204 is fixed to the fixing rod 211 on the side wall 201, and the other end is tightened and fixed to the fixing rod 211.

[0036] Multiple sleeves 212 are provided on both sides of the film, and a sliding side rope 204 is provided in the sleeves. Gaps are left between the sleeves, and the side ropes protrude into loops at these gaps for easy operation. This design allows the side ropes to slide freely in the sleeves, making it easy to adjust the tension of the film and ensure that the film is flat and wrinkle-free.

[0037] A plurality of fixing rods 211 are fixed to the top edge of the side wall, and the side ropes 204 are passed around these fixing rods in sequence. The distribution and number of the fixing rods are determined according to actual needs, and usually the spacing is moderate to ensure that the film can be evenly stressed.

[0038] One end of the side rope 204 is fixed on the first fixed rod 211, and the other end is fixed on the last fixed rod 211 after tightening. In this way, it can be ensured that the side rope is evenly stressed over the entire length, so that the film is firmly fixed on the side wall.

[0039] Through multi-point fixing and uniform force, the film is firmly fixed to the side wall and can remain stable even in strong winds. The side rope can slide in the sleeve to adjust the tension of the film and ensure that the film is flat and wrinkle-free. If the film needs to be replaced or repaired, it can be easily removed by loosening the side rope. The system has a simple structure, low material cost, easy installation and maintenance, and is suitable for greenhouses of all sizes.

[0041] The two sides of the film 202 are tightened and fixed to the side walls 201 by side ropes 204, and the two ends of the film 202 are fixed to the front wall 206 and the rear wall 210 by pressure strips 205, and a plurality of pressure ropes 203 are installed on the outer surface of the film 202, and the two ends of the pressure ropes 203 are respectively fixed to the pressure strips 205 on the front wall 206 and the rear wall 210, and the pressure ropes 203 can fix the middle part of the film 202.

[0042] The two ends of the film 202 are rolled on the pressure strips 205, and the pressure strips 205 are fixed to the front wall 206 and the rear wall 210 by screws. This design ensures that the film is firmly fixed to the front and rear walls to prevent the film from falling off due to wind or other external forces. A plurality of pressure ropes 203 are provided on the film 202, and the two ends of the pressure ropes 203 are tightened and fixed to the pressure strips 205 on the front wall 206 and the rear wall 210 respectively. The pressure ropes 203 are arranged in the intervals of the frame, which further enhances the stability of the film, especially in windy weather.

[0043] Multiple fixing methods ensure that the film is firm and reliable in all directions and remains stable even in adverse weather conditions. The design of the side ropes and pressure ropes allows the tension of the film to be adjusted at any time to ensure that the film is flat and wrinkle-free. If the film needs to be replaced or repaired, it can be easily removed by loosening the side ropes and pressure ropes. The system has a simple structure and low material cost and is suitable for greenhouses of all sizes.
