Description

Technical Field

[0001] This utility model belongs to the field of facility agriculture and energy-saving building technology, specifically relating to an optically optimized greenhouse structure that combines a steep-slope front roof with a solid roof. Background Technology

[0002] Traditional solar greenhouses, as a major form of facility agriculture, have significant deficiencies in thermal performance. Their roof structures are typically symmetrical and use a fixed slope for single-sided light transmission, resulting in a large overall light-transmitting area. This fails to fully consider the seasonal changes in solar altitude angle and latitudinal differences, leading to low solar radiation utilization and a high load on indoor environmental control.

[0003] In winter, when the sun's altitude angle is low, existing roof angles are insufficient to effectively capture solar radiation, resulting in insufficient lighting and reduced heat storage capacity. This often leads to heat deficits indoors, necessitating reliance on external energy sources such as coal and electricity for heating, increasing production costs and carbon emissions. In summer, the sun's altitude angle increases, concentrating a large amount of direct radiation on the roof, easily causing a sharp rise in indoor temperature. This not only increases energy consumption for ventilation and shading for cooling but also increases the risk of heat damage to crops, affecting their normal growth.

[0004] The aforementioned problems are particularly prominent in mid-to-high latitude regions, where the solar altitude angle varies greatly between seasons. Existing roof structures cannot adapt to the dynamic changes in annual light and heat demand, making it difficult to achieve a balance between winter heat collection and summer shading. This results in low energy efficiency of greenhouses throughout the year and high environmental control costs, which is incompatible with the current requirements for green and low-carbon agricultural development.

[0005] Therefore, there is an urgent need to provide an optically optimized greenhouse structure that combines a steep-slope front roof with a solid roof. By setting a slope angle adapted to the latitude and an asymmetrical roof structure, effective regulation of solar radiation can be achieved, and the imbalance between cold and heat can be alleviated, thereby improving the passive energy saving and photothermal environment stability of the greenhouse structure.

[0021] Specifically, this embodiment provides an optically optimized greenhouse structure combining a steep-slope front roof and a solid roof, including a light-transmitting front roof 1, a solid top roof 2, a rear wall 3, internal support components 4, a first enclosure wall 5, and a second enclosure wall 6. The lower edge of the light-transmitting front roof 1 is fixed to the ground at an angle of 60°-80° with the ground, and the upper edge of the light-transmitting front roof 1 is fixedly connected to the upper edge of the solid top roof 2, so that the solid top roof 2 and the light-transmitting front roof 1 form a reverse-slope structure, which is beneficial for reflecting high-level sunlight in summer and reducing heat loss in winter. The upper end of the rear wall 3 is fixedly connected to the lower edge of the solid roof 2, and the lower end of the rear wall 3 is fixed to the ground. Internal support components 4 are installed inside the light-transmitting front roof 1, the solid roof 2, and the rear wall 3 to provide support and form an accommodating space. A first enclosure wall 5 and a second enclosure wall 6 are respectively installed at the front and rear ends of the accommodating space. The cross-sectional shapes of the first enclosure wall 5 and the second enclosure wall 6 are the same as the cross-sectional shape of the accommodating space to seal it. Furthermore, a movable door is installed on the first enclosure wall 5 to allow personnel to enter and exit. The greenhouse structure provided by this utility model effectively improves the transmittance of low-angle sunlight in winter through the steep slope design of the light-transmitting front roof 1. It effectively controls the excessive entry of solar radiation in summer through the shading and heat-insulating design of the solid roof 2. Furthermore, the reverse slope structure design of the light-transmitting front roof 1 and the solid roof 2 achieves the purpose of being warm in winter and cool in summer, reducing energy consumption. It can be widely used in facility agriculture in mid-to-high latitude regions.

[0022] In some possible implementations, the internal support assembly 4 includes: a main crossbeam 41, fixed to the connection between the translucent front roof 1 and the solid top roof 2; a first side crossbeam 42, parallel to the main crossbeam 41 and fixed to the translucent front roof 1; the first side crossbeam 42 being at the same height as the upper end of the rear wall 3; a second side crossbeam, parallel to the main crossbeam 41 and fixed to the solid top roof 2; and a column member 43, perpendicular to the main crossbeam 41, one end of the column member 43 fixed to the main crossbeam 41, and the other end of the column member 43... Fixed to the ground; a first purlin condition 44, which is perpendicular to the first side beam 42 and fixed to the through front roof; the first purlin condition 44 and the first side beam 42 are located in the same plane; a second purlin condition, which is perpendicular to the second side beam and fixed to the solid top roof 2; the second purlin condition and the second side beam are located in the same plane; a fastener 45, one end of which is fixed to the junction of the first purlin condition 44 and the first side beam 42, and the other end of which is vertically fixed to the upper end of the rear wall 3; the fastener 45 and the upper end of the rear wall 3 are at the same height.

[0023] Specifically, the internal support assembly 4 includes a main crossbeam 41, a first side crossbeam 42, a second side crossbeam (not shown in the figure), a column member 43, a first purlin condition 44, a second purlin condition (not shown in the figure), and a fastener 45. The main crossbeam 41 is fixed at the connection between the translucent front roof 1 and the solid top roof 2. The first side crossbeam 42 and the second side crossbeam are both parallel to the main crossbeam 41 and have the same extension direction. The first side crossbeam 42 is fixed to the translucent front roof 1 and, together with the first purlin condition 44, supports the translucent front roof 1. The second side crossbeam is fixed to the solid top roof 2. The roof 2, together with the second purlin condition, supports the solid top roof 2; the column member 43 is perpendicular to the main crossbeam 41, and one end of the column member 43 is fixed to the main crossbeam 41 and the other end is fixed to the ground, providing vertical load transfer for the greenhouse structure; one end of the fastener 45 is fixed to the junction of the first purlin condition 44 and the first side crossbeam 42, and the other end is vertically fixed to the upper end of the rear wall 3, and the fastener 45 is at the same height as the upper end of the rear wall 3, so that the fastener 45, the first purlin condition 44 and the second purlin condition form a triangular stable support system.

[0024] In some possible implementations, the column member 43 includes m columns, which are spaced apart on the main crossbeam 41. One end of each column is vertically fixed to the main crossbeam 41, and the other end of each column is vertically fixed to the ground. The first purlin member 44 includes m purlins, which are spaced apart on the through-roof. One end of each purlin is fixed to the main crossbeam 41, and the other end of each purlin is fixed to the ground. The middle of each purlin is fixedly connected to the first side beam. The fixing member 45 includes m vertical rods, one end of each vertical rod is fixed to the intersection of a corresponding purlin and the first side beam 42, and the other end of each vertical rod is fixed to the upper end of the rear wall 3. Wherein, m is a positive integer.

[0025] Furthermore, based on the required accommodating space, the dimensions of the translucent front roof 1, the solid top roof 2, and the rear wall 3 are fixed. The angle between the translucent front roof 1 and the ground is determined according to the variation of the solar altitude angle in mid-to-high latitude regions, thereby determining the shapes of the first enclosure wall 5 and the second enclosure wall 6. Based on the load-bearing capacity of the internal support structure, the number of columns and their spacing are determined. In this application, the distance between two adjacent columns is 2.5-3.5m, thereby determining the distance between two adjacent purlins and the distance between two adjacent vertical members.

[0026] In some possible implementations, the translucent front roof 1 is made of polycarbonate panels or glass.

[0027] In some possible implementations, the solid top roof 2 is made of metal insulation panels.

[0028] In this application, the translucent front roof 1 is made of highly translucent materials such as polycarbonate sheets or glass, and its steep slope design increases the vertical incidence of solar radiation in winter while preventing excessive high-angle direct sunlight from entering the greenhouse structure in summer. Meanwhile, the solid top roof 2 is made of opaque heat-insulating materials such as metal insulation panels. This not only blocks high-level solar radiation in summer and reduces the indoor heat load, but also maintains the indoor temperature under the influence of snow accumulation in winter. The reverse slope design of the translucent front roof and the solid top roof 2 ensures that the greenhouse structure reflects high-level sunlight in summer and reduces heat loss in winter, thus ensuring that the temperature inside the greenhouse structure meets the requirements.

[0029] In some possible implementations, the rear wall 3 is made of concrete.

[0030] In some possible implementations, both the first enclosure wall 5 and the second enclosure wall 6 are made of polystyrene board composite layers.

[0031] In some possible implementations, the internal support assembly 4 is made of steel frame or aluminum alloy.

[0032] In this application, the rear wall 3 is made of concrete to improve the load-bearing capacity of the greenhouse structure. The first enclosure wall 5 and the second enclosure wall 6 are both made of polystyrene board composite layer to improve the heat preservation effect of the greenhouse structure. Furthermore, internal support components 4 are used to support the greenhouse structure. The internal support components 4 are made of steel frame or aluminum alloy and are used to support the light-transmitting front roof 1 and the solid top roof 2, as well as to bear wind and snow loads, to ensure the acceptance standards and safe use of the greenhouse structure.

[0033] In summary, compared with the prior art, this utility model has the following advantages: (1) This utility model has an asymmetrical structure with a light-transmitting front roof and a solid top roof with a reverse slope design. Combined with the changes in the solar altitude angle in mid-to-high latitude regions, it can adapt to the changes in the solar path throughout the year, passively regulate the thermal balance in the greenhouse structure, and achieve significant energy-saving effects.

[0034] (2) The solid roof of this utility model is made of opaque heat insulation material, which can both shade the sun and bear the weight of snow, so as to avoid excessively high temperature in summer and excessively low temperature in winter.
