Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to a greenhouse with a novel ventilation structure of a simple multi-span automatic roller shutter device. Background Technology

[0002] A greenhouse is a facility that allows light to pass through and provides insulation (or heating) for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield, and is often used for cultivating or raising seedlings of warm-season vegetables, flowers, and trees. Greenhouses come in many types, categorized by their roof frame materials, lighting materials, shape, and heating conditions. Traditional simple multi-span greenhouses mostly use side ventilation. If the ventilation openings are set too low, ventilation is insufficient, and air exchange at the top is impossible; if the openings are set too high, cold air cannot easily enter the bottom of the greenhouse, resulting in poor air exchange between the upper and lower layers, significant temperature and humidity stratification, and high humidity in the lower layers, which easily breeds diseases. Based on this, this utility model proposes a new ventilation structure for a simple multi-span greenhouse with an automatic rolling shutter device. Utility Model Content

[0003] The purpose of this invention is to provide a new type of ventilation structure for greenhouses with a simple multi-span automatic rolling shutter device, thereby solving the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a simple multi-span automatic roller shutter device for greenhouses with a novel ventilation structure. It includes several equidistant columns, with an upwardly inclined front slope between adjacent columns and a downwardly inclined rear slope behind the front slope. The bottom of the rear slope is located on the upper surface of the next front slope. A roller shutter machine is installed on the front slope, wound with two steel wire ropes, which are respectively connected to two reinforcing steel bars. A clamp is provided between the two reinforcing steel bars. Ventilation openings one and two are respectively provided on the front and rear slopes. A roller shutter machine limiting steel bar is installed above the front slope, supported by reinforcing steel bars on the columns. A shade net support is provided on the side of the limiting steel bar away from the roller shutter machine, and shade nets are installed between adjacent shade net supports.

[0006] Furthermore, the plurality of columns include a front column located on the front side and a rear column located on the rear side, and a plurality of intermediate columns are equidistantly arranged between the front column and the rear column.

[0007] Furthermore, the slope of the front slope is less than the slope of the back slope.

[0008] Furthermore, the bases of several of the columns are set on concrete pile foundations, which are buried underground.

[0009] Furthermore, side wall strips are provided on the upper part of several of the columns, and the side wall strips are driven to move up and down by a roller blind mechanism, which is provided with a support rod.

[0010] Furthermore, the upper part of the column is provided with a circumferential ventilation opening, which is located between 1 meter and 3.2 meters above the ground.

[0011] Furthermore, a film winding mechanism is provided on the inner side of the sidewall strip.

[0012] Furthermore, several of the aforementioned roller blinds are equipped with support rods 2, wherein the end of the support rod 2 located away from the roller blind is on the ground, and the ends of the other support rods 2 located away from the roller blind are on the front slope.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model relates to a simple, multi-span automatic rolling shutter greenhouse system. Air enters through the circumferential vents and exits through two top vents, creating a "chimney effect." Hot air exits from the top, while cool air enters through the side walls, improving ventilation efficiency. Furthermore, the dual top exhaust design of vents one and two allows for air circulation—low-intake, high-outtake—even when vent one is closed, enabling air to enter through the circumferential vents and exit through vent two. This is suitable for high-density planting areas, avoiding the problem of low ventilation efficiency. In summary, this utility model's simple, multi-span automatic rolling shutter greenhouse system features a simple structure, convenient operation, and good ventilation efficiency.

[0020] like Figure 1-3 As shown, a novel ventilation structure for a greenhouse with a simplified multi-span automatic rolling shutter device includes several columns arranged at equal intervals. These columns include front columns 2 at the front and rear columns 4 at the rear. Several intermediate columns 3 are installed at equal intervals between the front columns 2 and the rear columns 4. An upwardly inclined front slope 9 is installed between adjacent columns. A downwardly inclined rear slope 16 is installed behind the front slope 9, with the bottom of the rear slope 16 located on the upper surface of the next front slope 9. The slope of the front slope 9 is less than the slope of the rear slope 16. Ventilation openings 15 and 17 are respectively provided on the front slope 9 and the rear slope 16. Ventilation opening 15 is exposed when the curtain is rolled up for ventilation, and is covered when the curtain is unrolled, preventing ventilation.

[0021] A roller shutter machine 13 is installed on the front slope 9. The roller shutter machine 13 is wound with steel wire rope 20 and steel wire rope 21. Steel wire rope 20 and steel wire rope 21 are respectively connected to clamping steel bars 18 and 19. A clamping blanket is installed between the clamping steel bars 18 and 19. By starting the roller shutter machine 13, the steel wire rope 20 and steel wire rope 21 are moved. The tension generated by the movement of steel wire rope 20 and steel wire rope 21 causes the clamping steel bars 18 and 19 to move horizontally, thereby realizing the rolling up or unfolding of the clamping blanket.

[0022] A roller shutter machine limiting square steel 11 is installed above the front slope 9. The roller shutter machine limiting square steel 11 is installed on the column by reinforcing steel bars 10. The roller shutter machine limiting square steel 11 acts as a rigid blocking structure to directly limit the movement range of the roller shutter machine 13. When the clamping steel bar moves to the limit position with the steel wire rope, the roller shutter machine limiting square steel 11 will physically block its continued movement to prevent over-rolling (causing the quilt strips to stack too high) or over-unrolling (the quilt strips completely detach from the canopy). A sunshade net support 12 is installed on the side of the roller shutter machine limiting square steel 11 away from the roller shutter machine 13, and a sunshade net 22 is installed between adjacent sunshade net supports 12.

[0023] The bottoms of several of the columns are installed on concrete pile foundations 1, which are buried underground. Specifically, in this embodiment, the concrete pile foundations 1 are placed around the perimeter of the multi-span greenhouse. In addition, a column is installed at a spacing of 5 meters × 6 meters in the middle of the interior of the greenhouse to support the front slope 9 of the multi-span greenhouse.

[0024] Side wall strips 6 are installed on the upper part of several of the columns. The side wall strips 6 are driven to move up and down by a roller blind mechanism 7, which is equipped with a support rod 8. A film rolling mechanism is installed on the inner side of the side wall strips 6. The film rolling mechanism also realizes the rolling up and unrolling of the film through the roller blind mechanism 7.

[0025] The upper part of the column has a circumferential ventilation opening 5, which is located between 1 meter and 3.2 meters above the ground. A bottom membrane 23 is installed at the bottom of the circumferential ventilation opening 5, specifically at a position 1 meter above the ground. The circumferential ventilation opening 5, together with the top ventilation openings 15 and 17, form a "chimney effect," meaning hot air is exhausted from the top, while cold air enters from the side wall, creating a low-intake, high-exhaust configuration that improves ventilation efficiency.

[0026] Several of the roller blinds 13 are equipped with support rods 14, wherein the end of the support rod 14 on the far left is located on the ground, and the ends of the other support rods 14 are located on the front slope 9.

[0027] The operation process of this utility model is as follows:

[0028] In winter, vent 17 can be either normally closed or partially closed depending on actual needs. Every morning when the sun rises, the roller shutter 13 can be controlled to roll up the blanket to the front of vent 15 and stop. In order to achieve the needs of heat preservation and sunlight, vent 15 is not opened. At the same time, the roller shutter mechanism 7 rolls up the side wall strip 6 facing the sun. When the temperature of the greenhouse is too high at noon, the roller shutter 13 can be controlled to roll up the blanket to the roller shutter limit square steel 11, and the blanket is completely rolled up. Ventilation 15 is opened (the roller shutter mechanism at the circumferential ventilation vent 5 is opened depending on the situation) to achieve ventilation and cooling functions. In summer, vent 17 is always open. Every morning when the sun rises, the roller shutter machine 13 can be controlled to roll up the blanket, and the opening state of vent 15 can be controlled by the degree of rolling up. At the same time, the roller shutter mechanism 7 rolls up the side wall strip 6 facing the sun. When the temperature of the greenhouse is too high at noon, the roller shutter machine 13 can be controlled to roll up the blanket to the roller shutter machine limit steel 11, and the blanket is completely rolled up. Ventilation 15 is fully opened, and the roller shutter mechanism at the circumferential ventilation opening 5 is also activated and opened. At this time, hot air is discharged from the top, and cold air enters from the circumferential ventilation opening 5 on the side wall. The circumferential ventilation opening 5, together with the top vent 15 and vent 17, form a "chimney effect", which improves the ventilation efficiency and meets the ventilation and cooling needs.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
