Description

Technical Field

[0001] This invention relates to the field of greenhouse technology in agriculture, and in particular to a combined solar greenhouse that extends the duration of sunlight. Background Technology

[0002] With the development of greenhouse technology, modular solar greenhouses have become mainstream due to their simple construction and good heat preservation. Patent application number CN202110556951 discloses a modular solar greenhouse with high-efficiency light-gathering; patent application number CN202210387240 discloses a high-efficiency solar greenhouse using underground insulation; and patent publication number CN113243230A discloses a modular solar greenhouse containing independent enclosed areas. These three types of greenhouses address the problems of existing greenhouse technologies from different angles, greatly promoting the development of greenhouse technology in agriculture. However, they all share a common drawback: the function of the east and west side walls of the greenhouse arch slope is limited to heat preservation, while the functions of light gathering and ventilation are entirely accomplished by the arch slope. Therefore, the insulation of the side walls is fixed, but this structure results in shadows on the east and west side walls of the greenhouse, affecting ventilation. Because the sunlight is weak and at a low angle in the morning, especially around the winter solstice, the sunlight intensity is lowest at this time, resulting in the largest shadow on the east side wall of the greenhouse. Figure 7 As shown, the west wall began to cast shadows starting at 1:30 PM. As the sun moved, the angle of sunlight changed continuously, and the height and area of ​​the shadow on the side wall also changed accordingly. Table 1 records the changes in the angle of sunlight, the extension multiple of the shadow on the side wall (east wall before 12:00 PM, west wall after 1:00 PM), and the area of ​​shadow shading for a greenhouse with a main structure height of 5.5 meters, a side wall height of 4 meters, and a span of 12 meters, from 8:30 AM when the arched slope insulation blanket was rolled up to 4:30 PM when it was lowered.

[0003] Table 1: Greenhouse Light Statistics, December 21, 2021

[0004]

[0005] Overall, the east wall blocks at least 68 square meters of light in the morning, and the west wall blocks at least 76 square meters in the afternoon. This means that approximately 150 square meters of plants near the two side walls will experience significant insufficient sunlight. The most direct negative consequences of insufficient light are twofold: firstly, with the improvement of greenhouse heating technology, the overall temperature of the greenhouse during the day can reach above 20 degrees Celsius; secondly, the lack of light in certain areas leads to high relative humidity, and this dampness and darkness is a breeding ground for pests and diseases. Once plants that have been growing for two years are affected by pests and diseases, the consequences can range from reduced yields to total crop failure, and it also increases the cost of using pesticides to combat pests and diseases. To compensate for this deficiency, many methods have been used in practice, such as: "reasonable watering," "ventilation and dehumidification," "mulching," "heating and dehumidification," "natural moisture absorption," "cultivation and dehumidification," and "increasing light transmittance." Some methods use intuitive "greenhouse dehumidifiers," and there are several related patents for greenhouse dehumidification. All of these efforts aim to improve the humid environment inside greenhouses and contribute to increased crop yields and income. While these methods have yielded varying degrees of success, they are all stopgap measures, failing to address the root cause of the problem in the structure of greenhouses. From the moment the insulation blankets are rolled up until they are put back up, the east and west sides of the greenhouse are blocked from sunlight for several hours. This shaded area inevitably hinders ventilation and dehumidification after the greenhouse has warmed up. Because the greenhouse is not warm enough, ventilation and dehumidification cannot be performed. In the afternoon, when the insulation blankets are lowered, the west wall's vents need to be closed early and the blankets put back up early due to the lower air temperature on the shaded side, making it difficult to remove moisture from the greenhouse. Therefore, current greenhouses are unusable during the hot spring, summer, and autumn seasons. The negative effects of this structural problem in greenhouses are becoming increasingly apparent, especially in large greenhouses with spans exceeding 20 meters, where the degree of wind shading and light blocking is even more severe. Many large greenhouses are therefore idle. Several related greenhouse patents have not addressed the root cause of this problem. How to solve the problems of shading and ventilation on the side walls of greenhouses to maximize economic benefits for growers is a bottleneck that urgently needs to be addressed in the design and construction of greenhouses. Summary of the Invention

[0006] To address the shortcomings of existing combined solar greenhouses where the east and west side walls cast shadows and block light, this invention provides a combined solar greenhouse that extends the duration of sunlight. The insulation blankets on the side walls are installed using a rolling shutter mechanism, which can be rolled up and down together with the arched slope insulation blankets, ensuring that sunlight reaches every corner of the greenhouse to the maximum extent. This makes the air inside the greenhouse drier, reduces pests and diseases, and achieves the goal of increasing production and income.

[0007] The technical solution of this invention is: a combined solar greenhouse for extending the duration of sunlight, comprising a rear wall, two side walls, arch beams, crossbeams, an arch slope film, a fixed insulation body, an arch slope rolling shutter machine I, a concealed frame, an arch slope with an extended arch slope, an EVA insulation body, an insulation blanket fastening device I, an arch slope insulation blanket I, and ventilation systems I and II. Several spaced arch beams and several spaced crossbeams perpendicularly form an arch slope, with the portion of the arch beams outside the rear wall forming an extended arch slope. The arch slope film is placed on the arch slope, and ventilation systems I and II are located at the upper and lower parts of the arch slope, respectively. The arch slope insulation blanket... I. The EVA insulation body I is installed on the film I via the arch slope rolling shutter machine I. The EVA insulation body I is installed on the outside of the arch slope film I and located at the lower part of the arch slope. The concealed baffle is installed at the end of the extended arch slope. The fixing boxes of the two sets of insulation blanket fastening devices I are installed on both sides of the bottom corner of the arch slope. The rollers of the two sets of fastening devices I are respectively installed at both ends of the roller shaft of the arch slope rolling shutter machine I. The fixed insulation body is installed on the outside of the rear wall, on the outside of the junction of the two side walls and the arch slope, and on the lower part of the outside of the two side walls. The side wall film is installed on the parts of the two side walls without fixed insulation body. The side wall insulation blanket is installed on the side wall film via the side wall rolling shutter machine.

[0008] Furthermore, the sidewall insulation blanket includes sidewall insulation blanket II and sidewall insulation blanket III. Sidewall insulation blanket II is placed on the side closest to the rear wall, and sidewall insulation blanket III is placed on the side closest to the bottom corner of the arch slope. At the junction of sidewall insulation blanket II and sidewall insulation blanket III, sidewall insulation blanket II presses on sidewall insulation blanket III. Sidewall insulation blanket II is set by sidewall roller shutter machine II, and sidewall insulation blanket III is set by sidewall roller shutter machine III. Insulation blanket fastening device II is set at the corresponding position of the motor of sidewall roller shutter machine II at the bottom of the sidewall, and insulation blanket fastening device III is set at the corresponding position of the motor of sidewall roller shutter machine III at the bottom of the sidewall. The distance between insulation blanket fastening device II and the sidewall is less than the distance between insulation blanket fastening device III and the sidewall. The roller of insulation blanket fastening device II is set at the motor end of the roller shaft II of sidewall roller shutter machine II, and the roller of insulation blanket fastening device III is set at the motor end of the roller shaft III of sidewall roller shutter machine III.

[0009] Furthermore, the side wall roller shutter III, located near the bottom corner of the arch slope, is set along the slope of the arch slope, and the diameter of the roller of the side wall roller shutter III gradually decreases from the motor end.

[0010] Furthermore, single and double slots are respectively set on the outer arch slope near the rear wall and on the two side walls near the rear wall, with the double slots located inside the single slots; double slots are also set at the upper and lower ends of the two side walls and on both sides of the arch slope; the two sides of the fixed insulation body of the rear wall extend around the columns of the rear wall and into the area of ​​the two side walls, with the inner composite film of the fixed insulation body set in the corresponding single slot and the outer insulation body set in the corresponding outer slot of the double slot; the fixed insulation bodies set at the upper part of the two side walls and the junction of the two sides of the arch slope and the fixed insulation bodies set at the lower part of the two side walls are respectively set in the outer slot of the corresponding double slot; the periphery of the side wall film is respectively set in the inner slot of the corresponding double slot.

[0011] Furthermore, an air-conditioning system III is installed at the lower part of the side wall, and an air-conditioning system IV is installed in the area corresponding to the side wall insulation blanket II at the upper part of the side wall.

[0012] Furthermore, a columnar thermal insulation body II is installed at the upper end of the fixed thermal insulation body at the lower end of the side wall.

[0013] Preferably, the width of sidewall insulation blanket II is 65% of the total span of the greenhouse, and the width of sidewall insulation blanket III is 40% of the total span of the greenhouse.

[0014] Preferably, the width of sidewall insulation blanket II is 85% of the total span of the greenhouse, and the width of sidewall insulation blanket III is 20% of the total span of the greenhouse.

[0015] The beneficial effects of this invention are as follows: The greenhouse of this invention is equipped with rolling shutters on both side walls, allowing the side wall insulation blankets and arched slope insulation blankets to be rolled up and down together, increasing the light transmission area on both sides by about 85% and significantly removing moisture. This directly results in increased light and temperature, ensuring high-quality light on both sides and the bottom corners of the greenhouse. The high light and temperature facilitate ventilation to remove moisture, directly reducing the risk of pests and diseases caused by dampness and lowering the cost of pesticides and labor. Simultaneously, each side wall has two ventilation openings, one above the other, for better ventilation and further moisture removal, extending the greenhouse's growing advantages into the summer. The use of double-slot installation to fix the insulation and film makes film replacement easier, significantly reducing operating costs and making it more suitable for large-scale promotion. The advantages are particularly pronounced for ultra-large greenhouses with a span of over 20 meters. Attached Figure Description

[0023] Detailed implementation method

[0024] like Figures 1 to 6 As shown, a combined solar greenhouse for extending the duration of sunlight includes a rear wall 1-1, two side walls 1-2, an arch beam 2, a crossbeam 3, an arch slope film 4-1, a fixed insulation body 5, an arch slope rolling shutter machine I 8-1, a concealed frame 9, an arch slope 10 with an extended arch slope 10-1, an EVA insulation body 11, an insulation blanket fastening device I 12-1, an arch slope insulation blanket I 14-1, and ventilation systems I 15-1 and II 15-2. The rear wall 1-1 and the two side walls 1-2 are composed of several columns perpendicular to the ground. One end of the arch beam 2 is welded to the upper end of the column of the rear wall 1-1 and extends outward. The extension distance is 0.5 to 0.6 meters larger than the diameter of the arch slope insulation blanket I 14-1 when rolled up. One end is fixed to the ground by a ground anchor. The crossbeam 3 is welded perpendicularly to the arch beam 2. Several crossbeams are arranged at intervals. The arch slope 10 is formed by the arch beam 2 and several intermittently arranged crossbeams 3. The arch beams 2 outside the rear wall 1-1 form the extended arch slope 10-1. That is to say, the length of the extended arch slope 10-1 is 0.5 to 0.6 meters larger than the diameter of the arch slope insulation blanket when rolled up. This provides sufficient space for the multi-layer arch slope insulation blanket to be rolled up. A concealed baffle 9 is welded to the outer end of the extended arch slope 10-1. The greenhouse frame, including the columns of the rear wall 1-1, the columns of the side walls 1-2, the arch beams 2, the crossbeams 3, and the concealed baffle, are all made of high-galvanized pipes, completing the greenhouse frame. A ventilation system II 15-2 is constructed on the upper part of the arch slope 10, and a ventilation system I 15-1 is assembled on the lower part of the arch slope 10 to create effective convection. To prevent strong winds from damaging the greenhouse, insulation blanket fastening devices I 12-1 are installed on both sides of the bottom corner of the arch slope 10. The fixing box of the thermal insulation blanket fastening device I12-1 is installed on both sides of the bottom corner of the arch slope 10, and the rollers of the two sets of fastening devices I are respectively fixed to both ends of the roller shaft of the arch slope roller shutter machine I8-1.

[0025] To facilitate the replacement of the sidewall membrane 4-2, a slot 7 is installed on the crossbeam 3 at the bottom corner of the arch slope 10, about 40 cm from the ground. Double slots 7 are installed on the sidewall columns of the sidewall 1-2, about 40 cm from the ground. Double slots 7 are also installed on both sides of the arch slope 10, about 30 cm from the edge arch beam 2. Double slots 7 are also installed on the upper end of the sidewall 1-2, about 30 cm from the arch beam 2. The fixed insulation body 5 at the bottom corner of the arch slope 10 and the lower part of the sidewall 1-2 is fixed in the outer slot 7-1 of the corresponding double slot 7. The fixed insulation body 5 at the junction of the arch slope 10 and the two sidewalls 1-2 is fixed in the inner slot 7-1 of the corresponding double slot 7. The sidewall membrane 4-2 of the two sidewalls 1-2 is fastened and fixed with the inner slot 7-2 of the corresponding double slot 7.

[0026] Double slot 7 and single slot 6 are fixedly installed in the two side walls 1-2 near the rear wall 1-1, respectively, with the double slot 7 located inside the single slot 6;

[0027] To facilitate the replacement of the arch slope film 4-1, the fixed insulation body 5 of the rear wall is laid as follows: To ensure light inside the greenhouse, the white film side of the inner composite film 5-1 of the fixed insulation body 5 of the rear wall faces inward. The bottom end of the fixed insulation body 5 of the rear wall is fixed by a single slot. Starting from the bottom end of the rear wall 1-1, it is laid sequentially along the lower end face of the rear wall 1-1, the arch slope 10-1, the outer side of the concealed frame 8, and the upper end face of the extended arch slope 10-1. The top end is installed on the extended arch slope 10-1. The inner composite membrane 5-1 of the fixed insulation body 5 is fastened and fixed with the single slot 6 at the corresponding position. The outer insulation blanket 5-2 of the fixed insulation body 5 of the rear wall is fixed in the outer slot 7-1 of the double slot 7 at the corresponding position. The two sides of the fixed insulation body 5 of the rear wall 1-1 extend around the rear wall columns at the corresponding positions to the area of ​​the side wall 1-2, and the inner composite membrane 5-1 is fastened and fixed with the single slot 6 at the corresponding position. The outer insulation blanket 5-2 is fastened and fixed with the outer slot 7-1 of the double slot 7 at the corresponding position. The bottom end of the arched slope film 4-1 is inserted into the inner groove 7-2 of the double groove 7 and laid upward along the arched slope 10. During the laying of the arched slope film 4-1, ventilation system II 15-2 and ventilation system I 15-1 are left open for greenhouse ventilation. The top end of the arched slope film 4-1 is inserted into the inner groove 7-2 of the double groove 7 on the outer arched slope 10-1. The two sides of the arched slope film 4-1 are inserted into the inner groove 7-2 of the double groove 7 on both sides of the arched slope 10.

[0028] Thus, when the side wall membrane 4-2 needs to be replaced, it is only necessary to remove the arch slope side wall membrane 4-2 from the inner slot 7-2 of the double slot 7; when the arch slope membrane 4-1 needs to be replaced, it is only necessary to remove the arch slope membrane 4-1 from the inner slot 7-2 of the double slot 7, without affecting the high-cost rear wall fixed insulation body 5.

[0029] For better insulation, EVA insulation body I11-1 is installed on the upper end of the fixed insulation 5 at the lower part of the side wall 1-2, and EVA insulation body II11-2 is installed on the fixed insulation body 5 at the bottom corner of the arch slope 10.

[0030] On the fixed insulation body 5 at the upper end of the two side walls 1-2, insulation strips exceeding 30 cm of the arch slope 10 are glued to form arch slope windbreak I 17-1; on both sides of the rear wall 1-1, insulation strips exceeding 30 cm of the rear wall edge are glued to form rear wall windbreak II 17-2.

[0031] The upper end of the arch slope insulation blanket I14-1 is connected to the outer layer insulation blanket 5-2 of the fixed insulation body 5 on the rear wall. The remaining part is set by the arch slope rolling shutter machine I8-1. When the arch slope insulation blanket I14-1 is rolled up, it stops outside the outer arch slope 10-1 and is blocked by the concealed baffle 9. Since the length of the outer arch slope 10-1 is 0.5 to 0.6 meters larger than the diameter of the arch slope insulation blanket I14-1 when it is rolled up, it can be fully guaranteed that the arch slope insulation blanket I14-1 stops outside the rear wall 1-1 when it is rolled up. On the side, it will not affect the lighting near the rear wall 1-1 inside the greenhouse; when the arch slope insulation blanket I14-1 is unfolded, the arch slope rolling shutter machine I8-1 drives the arch slope insulation blanket I14-1 to be laid down along the outer arch slope 10-1 and arch slope 10, covering the bottom corner insulation body I11-1, and laying it to the ground. The roller of the arch slope rolling shutter machine I8-1 drives the roller of the insulation blanket fastening device I12-1 to roll into the fixed box of the insulation blanket fastening device I12-1. The baffle inside the box fixes the arch slope insulation blanket I14-1.

[0032] Due to the curvature limitation of the arch slope 10, in order to maximize sunlight reception, a segmented rolling method is adopted. The sidewall insulation blanket is divided into two parts: sidewall insulation blanket II14-2 and sidewall insulation blanket III14-3. The upper end of sidewall insulation blanket II14-2 is fixed to the fixed insulation body 5 at the upper end of the sidewall near the rear wall, and the upper end of sidewall insulation blanket III14-3 is set on the fixed insulation body 5 at the upper end of the sidewall near the bottom corner of the arch slope 10. They are pressed and fixed with flat steel 16 respectively. At the junction 18 of sidewall insulation blanket II14-2 and sidewall insulation blanket III14-3, sidewall insulation blanket II14-2 presses on sidewall insulation blanket III14-3, with a pressing width of 30~40 cm. Sidewall insulation blanket II14-2 is set by sidewall rolling machine II8-2. Side wall insulation blanket Ⅲ14-3 is installed via side wall roller shutter machine Ⅲ8-3; the housing of insulation blanket fastening device Ⅱ12-2 is installed at the corresponding position of the motor of side wall roller shutter machine Ⅱ8-2 at the bottom end of side wall 1-2, the roller of insulation blanket fastening device Ⅱ12-2 is fixed to the motor end of the roller shaft Ⅱ8-2-4 of side wall roller shutter machine Ⅱ8-2, the housing of insulation blanket fastening device Ⅲ13-3 is installed at the corresponding position of the motor of side wall roller shutter machine Ⅲ8-3 at the bottom end of side wall 1-2, the roller of insulation blanket fastening device Ⅲ13-3 is fixed to the motor end of the roller shaft Ⅲ8-3-4 of side wall roller shutter machine Ⅲ8-3, and the distance between the housing of insulation blanket fastening device Ⅱ12-2 and side wall 1-2 is less than the distance between the housing of insulation blanket fastening device Ⅲ13-3 and side wall 1-2.

[0033] Due to the curvature of the arch slope 10, the heights of the two sides of the sidewall 1-2 corresponding to the sidewall insulation blanket Ⅲ14-3 are different. The roller Ⅲ8-3-4 of the sidewall rolling shutter machine Ⅲ8-3, which is extended near the bottom corner of the arch slope 10, is installed along the slope of the arch slope 10. At the same time, the diameter of the roller Ⅲ8-3-4 gradually decreases from the end near the motor. The range of change in the diameter of the roller Ⅲ8-3-4 is selected according to the thickness of the sidewall insulation blanket Ⅲ14-3 to control the speed at which the sidewall insulation blanket is rolled up and down. Therefore, when the sidewall insulation blanket Ⅲ14-3 is lowered, the edge in the middle of the sidewall 2-2 is curved.

[0034] For better ventilation and moisture prevention, an air-opening system Ⅲ15-3 is installed at the lower part of side wall 1-2, and an air-opening system Ⅳ15-4 is installed in the area corresponding to the upper side wall insulation Ⅱ14-2 of side wall 1-2.

[0035] For greenhouses with a span of 15 meters or less, the width of sidewall insulation blanket II14-2 is 65% of the total span of the greenhouse, and the width of sidewall insulation blanket III14-3 is 40% of the total span of the greenhouse.

[0036] For greenhouses with a span of 20 meters or more, the width of the sidewall insulation blanket II14-2 is 85% of the total span of the greenhouse, and the width of the sidewall insulation blanket III14-3 is 20% of the total span of the greenhouse.

[0037] When lowering the side wall insulation blanket, first start the side wall roller shutter machine Ⅲ8-3 to lower the side wall insulation blanket Ⅲ14-3. Stop when the roller of the side wall roller shutter machine Ⅲ8-3 rolls into the housing of the insulation blanket fastening device Ⅲ12-3. The stop bar of the insulation blanket fastening device Ⅲ12-3 blocks the roller of the side wall roller shutter machine Ⅲ8-3 and fixes it. Then start the side wall roller shutter machine Ⅱ8-2 to lower the side wall insulation blanket Ⅱ14-2. Stop when the roller of the side wall roller shutter machine Ⅱ8-2 rolls into the housing of the insulation blanket fastening device Ⅱ12-2. The stop bar of the insulation blanket fastening device Ⅱ12-2 blocks the roller of the side wall roller shutter machine Ⅱ8-2 and fixes it.

[0038] When the side wall insulation is rolled up, first start the side wall rolling shutter machine II8-2. Stop when the side wall rolling shutter machine II8-2 passes the edge of the fixed insulation body 5 at the upper end of the side wall 1-2. Then start the side wall rolling shutter machine III8-3. Stop when the side wall rolling shutter machine III8-3 passes the edge of the fixed insulation body 5 at the upper end of the side wall 1-2.

[0039] With the automatic control system installed, the advantages of the solar greenhouse of this invention will be further highlighted, resulting in lower operating costs and better performance.
