Description

Technical Field

[0001] The present invention relates to the technical field of crop cultivation, and in particular to a double-arch and double-film temperature-controlled greenhouse. Background Art

[0002] With the advent of high-molecular-weight polymers like polyvinyl chloride and polyethylene, plastic film has become widely used in agriculture. Greenhouses, originally specialized for vegetable production, have become increasingly widespread with the development of production. Currently, greenhouses are used for growing potted and cut flowers; in fruit production, for cultivating grapes, strawberries, watermelons, melons, peaches, and citrus; in forestry, for raising seedlings and ornamental trees; and in animal husbandry, for raising silkworms, chickens, cattle, pigs, fish, and fry.

[0003] In the early days of greenhouse use, single-film and single-arch greenhouses were used. A single-layer plastic film was supported by a single arch to keep vegetables, fruits, etc. in the greenhouse warm, making it easier to cultivate crops in places or seasons with lower temperatures. However, although the single-arch and single-film structure can bring greater light intensity during the day, it cannot block excessive light intensity in the summer, which affects the growth of crops that require less light intensity. At the same time, due to the single film, the temperature in the greenhouse cannot be well controlled. The temperature in the greenhouse will be too high due to the high light intensity during the day, and at night, due to only a single film, the temperature insulation effect in the greenhouse is poor. When the temperature is too low at night, especially in winter nights, it will cause a large temperature difference in the greenhouse, which will easily affect the normal growth of the cultivated crops, and thus affect their yield and quality.

[0004] With the development of society, the use of greenhouses has developed into double-arch double-film greenhouses. Double-arch double-film can effectively overcome the shortcomings of single-arch single-film plastic greenhouses, such as small span, poor indoor environmental stability, and relatively short planting cycle. However, in many areas with large temperature differences between day and night, the use of double-arch double-film to cultivate crops also affects their normal growth and yield. Although the double-arch double-film greenhouse can maintain stable heat preservation, its double-layer structure will fix the air between the double layers of film, blocking wind convection, affecting ventilation, and failing to regulate temperature well. In the summer when the temperature is high, the sunshine hours are long, and the sunshine intensity is high, it is easy to cause the greenhouse to be in a high and stuffy state for a long time, thereby affecting the growth of the cultivated crops.

[0005] On the other hand, many existing double-arch and double-film greenhouse structures are not equipped with sunshade nets, and the intensity and duration of sunlight, as well as the greenhouse temperature, cannot be more effectively regulated by the greenhouse film alone.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0026] (1) The double-arch double-film temperature-controlled greenhouse of the present invention is provided with a Dapeng frame and a greenhouse body. The Dapeng frame enables the double-layer film to be set around the greenhouse. The double-layer film can fix the air between the two layers when the external temperature is low, perform air isolation, prevent wind convection, and keep the greenhouse warm. By combining the opening and closing mechanisms provided on the greenhouse frame and the greenhouse body, as well as the fans and wet curtains provided on the outer horizontal surface of the greenhouse, when the temperature in the greenhouse is too high and needs to be adjusted, the air vents on the top of the greenhouse body and the greenhouse films on the inner and outer horizontal surfaces of the greenhouse can be opened through the opening and closing mechanisms, and then the temperature inside the greenhouse can be cooled and controlled through the fans and wet curtains. The temperature control is efficient and fast, and the high internal temperature is avoided to affect the cultivation of crops.

[0027] (2) The double-arch double-film temperature-controlled greenhouse of the present invention is provided with an internal temperature-regulating device. The internal temperature-regulating film is covered on the internal temperature-regulating device by two opening and closing mechanisms. The internal temperature-regulating film can be rolled up to the middle by the two opening and closing mechanisms during the day to open the internal temperature-regulating film, thereby increasing the space inside the greenhouse. During the daytime, when there is sunshine, especially when the sunshine time is long and the sunshine intensity is high, the interior of the greenhouse is cooled down. At night, especially in winter nights, the internal temperature-regulating film is closed by the opening and closing mechanism, which can keep the interior of the greenhouse warm and further prevent frost, thereby ensuring that crops grow in a good and suitable temperature environment.

[0028] (3) The opening and closing mechanism of the double-arch double-film temperature-controlled greenhouse of the present invention includes a motor and a reel. When the greenhouse film or the internal temperature-regulating film needs to be rolled up or released for ventilation and temperature control, the motor at the corresponding position can be controlled to start, and the rotation of the motor drives the reel to rotate, thereby continuously rolling up or releasing the greenhouse film or the internal temperature-regulating film at the corresponding position. Moreover, since the motor is slidably sleeved on the corresponding inner arch rod or outer arch rod or main column, the displacement caused by the reel rotating to roll up or release the greenhouse film or the internal temperature-regulating film can drive the motor to move on the sleeved position, which is convenient, fast and efficient to use.

[0029] (4) The double-arch double-film temperature-controlled greenhouse of the present invention is also provided with an external sunshade device and a temperature-regulating layer. When the temperature is too high, the external sunshade device blocks the light to prevent the crops from being exposed to high-intensity light for a long time. Combined with the temperature-regulating layer (the white plastic ground cloth in summer reflects light and lowers the temperature in the greenhouse, and the black paint in winter absorbs heat and stores heat in the soil, dissipating heat and keeping warm at night), the greenhouse temperature is accurately controlled to ensure that the temperature is suitable for crop growth, thereby ensuring crop yield and quality.

DETAILED DESCRIPTION

[0047] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Example 1

[0048] The present embodiment provides a double-arch double-film temperature-controlled greenhouse, comprising a greenhouse frame, an external sunshade device, several greenhouse bodies 1, several internal temperature-regulating devices 2 and a greenhouse film 3. The external sunshade device is arranged on the top of the greenhouse frame, and several greenhouse bodies 2 are arranged in sequence in the greenhouse frame. Several internal temperature-regulating devices 2 correspond to several greenhouse bodies, and each internal temperature-regulating device is arranged in a corresponding greenhouse body; the greenhouse film 3 is arranged at the lower part of the greenhouse frame and on the outer surface of the greenhouse body. In order to clearly show the internal structure of the double-arch double-film temperature-controlled greenhouse of the present invention, the present invention is shown in FIG. Figure 1-7 Neither of them indicates greenhouse film or internal temperature control film. Figure 8-15 The front side is an insect-proof net.

[0049] In this embodiment, the length direction of the greenhouse body is longitudinal, and the arrangement direction is transverse. The two outer side surfaces of the greenhouse frame extending in the longitudinal direction are longitudinal surfaces 4, and the two outer side surfaces extending in the transverse direction are outer transverse surfaces 5; the greenhouse frame is a cube formed by several rows of main columns 6, and the main columns of each two adjacent rows (the row mentioned in the present invention is a row of main columns extending in the longitudinal direction) are respectively arranged on both sides of the corresponding greenhouse body 1; the two longitudinal surfaces 4 and the two outer transverse surfaces 5 are respectively provided with three parallel support beams 7 from bottom to top, and an external sunshade beam 8 is provided at the top, and several secondary columns 9 are provided between adjacent main columns on the longitudinal surface and the outer transverse surface. In this embodiment, three secondary columns are provided between adjacent main columns on the longitudinal surface and the outer transverse surface, and the top of the secondary column is connected to the uppermost support beam 7.

[0050] In this embodiment, each outer transverse surface 5 is further provided with an inner transverse surface 10 structure, and the structure of the inner transverse surface 10 is the same as that of the outer transverse surface 5 with the support beam and the following portion. The inner and outer transverse surfaces are arranged to ensure that a double layer of greenhouse film 3 is provided in the transverse direction.

[0051] A plurality of fans 11 are evenly arranged between the two lower support beams on one outer transverse surface 5, and a wet curtain 12 is arranged between the two lower support beams on the other outer transverse surface. Figure 8 and 9 As shown, when the greenhouse films on the inner and outer horizontal surfaces are rolled up, the fan and the wet curtain can be used together to cool the greenhouse; two greenhouse doors 13 are provided on one of the longitudinal surfaces, as shown in FIG. Figure 12 As shown, to facilitate the entry and exit of staff, an X-shaped fixing member 14 is provided between the uppermost support beam of each longitudinal surface and the outer sunshade beam, as shown in FIG. Figure 13 As shown, the X-shaped fixing piece is mainly arranged on the upper right part of each longitudinal surface, which can strengthen the fixation of the greenhouse frame.

[0052] In this embodiment, two anti-insect support rods 15 are provided at both ends of each outer transverse surface and longitudinal surface, such as Figure 1 As shown, an insect-proof net 16 is provided between the two insect-proof support rods on each surface. The height of the insect-proof net is the same as the height of the auxiliary column. The insect-proof net in this embodiment is a 40-mesh insect-proof net, which can play an insect-proof role during the crop cultivation process.

[0053] The external sunshade device of this embodiment includes several sunshade line beams 17, several film drag lines 18 and external sunshade nets 19. The sunshade line beams are vertically crossed and arranged on the top of the greenhouse frame, and are respectively connected to the corresponding main columns 6 on the opposite sides; several film drag lines 18 are evenly arranged on the top of the greenhouse frame, and the two ends are respectively connected to the external sunshade beams 8 on the top of the two outer horizontal surfaces, and the external sunshade net 19 covers the top of the sunshade line beams and the film drag lines. Both the sunshade line beams and the film drag lines play a supporting role for the external sunshade net. The external sunshade net in the present invention can be a whole or divided into multiple parts for shading. Preferably, the greenhouse sunshade net in this embodiment can be divided into zones, and the top of the greenhouse frame can be divided into zones by parallel sunshade line beams. Each zone is covered with an external sunshade net. When in use, the degree of opening of the external sunshade net in each zone can be controlled according to the current light conditions (lighting time and intensity). This makes it more convenient to evenly control the light and temperature in the greenhouse. Figure 2 and 3 As shown, Figure 2 This is a schematic diagram of the overall structure without external sunshade nets and insect-proof nets. Figure 3 In order to facilitate the display of the internal structure, no external shading device is provided, nor is there an external shading beam.

[0054] Several triangular fixing members 20 are evenly arranged between the sunshade beams and the sunshade beams parallel to the horizontal direction or between the outer sunshade beams and the sunshade beams. In this embodiment, the sunshade beams with the same triangular fixing member are parallel to the horizontal direction. In other embodiments, they can be parallel to the longitudinal direction. Figure 1 As shown in or 2, since the number of greenhouse bodies cannot make all the triangular fixings complete, in this embodiment, there are only half of the triangular fixings close to the greenhouse door, which only needs to play the role of strengthening the connection. Two adjacent triangular fixings are spaced apart in the longitudinal direction, and an X-shaped fixing 14 is provided between the main columns separating the two adjacent triangular fixings. Two adjacent X-shaped fixings 14 are spaced apart in the longitudinal direction by a triangular horizontal fixing, and the X-shaped fixing is provided at the lower position of the main column; each main column is connected in a triangular shape through a reinforcing rod 21 and a sunshade line beam or an external sunshade beam connected thereto. The arrangement of the triangular fixing 20, the X-shaped fixing 14 and the reinforcing rod 21 is as shown in FIG. Figure 7 As shown, the overall stability and firmness of the greenhouse frame are increased.

[0055] The greenhouse body of this embodiment includes several rain gutters 22, several greenhouse support rods 23 and several arch structures. Several rain gutters and several greenhouse support rods correspond to the cross-arranged sunshade line beams. Several rain gutters and several greenhouse support rods are vertically cross-arranged below the sunshade line beams and are respectively connected to the corresponding main columns. The ends are connected to the uppermost support beams. The rain gutters 22 are parallel to the longitudinal direction, and the greenhouse support rods 23 are parallel to the transverse direction. The uppermost support beam on the longitudinal plane is also a rain gutter. The setting of the rain gutter can guide rainwater to both ends on rainy days to avoid rainwater accumulation on the gutter, causing leakage or damage to the device.

[0056] like Figure 4 As shown, the greenhouse frame structure is shown. The insect-proof net and the external sunshade net in the figure are not shown. The purpose is to clearly show the structural diagram of the interior that they cover. Figure 4 and 5 The arch structures in the figure only show the arch structures corresponding to the support poles or support beams of the greenhouse.

[0057] Several arched structures are evenly arranged longitudinally to form the greenhouse body 1. The arched structures include two curved outer arch rods 24. The lower ends of the two outer arch rods are connected to two adjacent rain gutters, and the upper ends are connected to each other to form a semicircular shape. The upper end of one outer arch rod extends obliquely upward and then bends downward to connect to the other outer arch rod. The obliquely extending outer arch rods of all greenhouse bodies extend in the same direction, meaning that the overall structure of all greenhouse bodies is the same.

[0058] The greenhouse film 3 is arranged on the surface of the greenhouse body and the outer surface of the greenhouse frame. The height of the greenhouse film arranged on the outer side of the greenhouse frame is the same as the height of the uppermost support beam, and the greenhouse film arranged on the outer side of the greenhouse frame is double-layered, that is, the outer surface of the outer transverse surface 5 and the inner transverse surface 10 are both provided with greenhouse film, and the inner and outer sides of the longitudinal frame are also provided with greenhouse film. Figure 10 and 11 As shown, the greenhouse film provided on the outer surface of the greenhouse frame and the greenhouse film provided on the greenhouse body form a whole.

[0059] The greenhouse body also includes four pull tubes 25, which extend horizontally and longitudinally to connect several arch structures. The four pull tubes 25 are respectively connected to each arch structure at the following positions: two outer arch rods 24, the connection between the tops of the two outer arch rods, and the bending part of the extended and bent outer arch rods; the four pull tubes are all used to support the greenhouse film provided on the arch structure.

[0060] The arched structure corresponding to the greenhouse support rod or the topmost support beam is also connected to the greenhouse support rod or the topmost support beam via three outer arch rod diagonal braces 26. One end of each of the three outer arch rod diagonal braces is connected to the corresponding greenhouse support rod or the topmost support beam below, and the other end is connected to the two outer arch rods and the connection point of the two outer arch rods. The outer arch rod diagonal braces connected to the connection point of the two outer arch rods are vertically arranged. The outer arch rod diagonal braces are used to support the outer arch rods, and then support the tension tubes and greenhouse film, ensuring the overall stability of the greenhouse body.

[0061] The internal temperature control device of this embodiment includes several internal arch rods 27 and internal temperature control films 28. Several internal arch rods are arranged under the corresponding greenhouse body and are evenly arranged in the longitudinal direction. The number of internal arch rods corresponds to the main columns on both sides of the corresponding greenhouse body, and the two ends of the internal arch rods are fixed to the main columns on both sides. Figure 14 and 16 As shown, the two ends of the inner arch rods at both ends of the internal temperature control device in the longitudinal direction are fixed on the corresponding main columns on the inner horizontal surface; the internal temperature control film covers the whole formed by several inner arch rods 27, and the highest point of the internal temperature control device is lower than the highest point of the auxiliary column 9.

[0062] The present invention Figure 5 exist Figure 4 On the basis of the increase of internal temperature control device, as shown in the following example: Figure 6 As shown, Figure 6 The figure shows a schematic diagram of the structure including the outer transverse surface 5, the inner transverse surface 10, the fan 11, the arch structure, the outer arch rod diagonal brace 26, the pull pipe 25, the rain gutter 22, the inner arch rod 27, etc.

[0063] The double-arch double-membrane temperature control greenhouse of the present application further comprises a plurality of opening and closing mechanisms, which comprise two motors 29 and a reel 30, the two ends of the reel being drivingly connected to the two motors; the opening and closing mechanisms are arranged on the two outer horizontal surfaces, the two inner horizontal surfaces, the greenhouse body and the inner temperature adjusting device; all the motors are connected to a power supply.

[0064] The opening and closing mechanisms arranged on the outer horizontal surface 5 and the inner horizontal surface 10 are arranged between the lower two support beams 7, the two motors 20 are respectively slidingly sleeved on the main columns 6 at the two ends of each surface, and the reel 30 is fixed to the lower end of the greenhouse film 3 of the corresponding surface; during use, the reel 30 is driven to rotate by the motor, thereby winding up or unwinding the greenhouse film upward or downward, so as to open or close the greenhouse film on the inner and outer horizontal surfaces, as shown in FIG. 6. Figure 15 The lowest support beam in the present application has a relatively low height, or the main column or the auxiliary column part below the lowest support beam is inserted into the soil, that is, when the reel is at the lowest position, the lowest support beam of the present application will not affect the temperature in the greenhouse due to its height.

[0065] In the present embodiment, the overall height of the greenhouse frame is 6800 mm, the longitudinal length is 41000 mm, the height of the uppermost support beam is 4000 mm, the height of the lowermost support beam is 200-300 mm, and the width and height of each inner temperature adjusting device are 8000 mm and 3000 mm, respectively.

[0066] The opening and closing mechanism arranged on the greenhouse body is arranged on the downwardly bent part of the extended and bent outer arch rod, the two motors 29 are respectively slidingly sleeved on the two downwardly bent parts of the two outer arch rods at the two ends of the greenhouse body, and the reel is fixed to the bottom end of the corresponding greenhouse film arranged on the part, and when the opening and closing mechanism winds up the greenhouse film on the part, an air outlet 31 is formed.

[0067] The number of the opening and closing mechanisms arranged on the inner temperature adjusting device is two, the two motors 29 of each opening and closing mechanism are respectively slidingly sleeved on the two inner arch rods 27 at the two ends of the inner temperature adjusting device, the two motors located on the same inner arch rod are arranged at the two ends of the inner arch rod 27, and the two reels 30 are respectively fixed to the two lateral end parts of the inner temperature adjusting film.

[0068] The opening and closing mechanism in the present application can be replaced by other film winding devices, as long as it can wind the film at the position where the film is needed.

[0069] When the greenhouse film or the inner temperature adjusting film needs to be wound up or unwound for ventilation and temperature adjustment, the motor at the corresponding position can be controlled to start, the motor is driven to rotate to drive the reel to rotate, thereby continuously winding up or unwinding the greenhouse film or the inner temperature adjusting film at the corresponding position, and since the motor is slidingly sleeved on the corresponding inner arch rod or outer arch rod or main column, the displacement of the reel caused by the rotation of the reel when winding up or unwinding the greenhouse film or the inner temperature adjusting film can drive the motor to move on the sleeved part, which is convenient, fast and efficient.
