Abstract
Description
Technical Field
[0001] This invention relates to the field of bio-agricultural technology, and in particular to an energy-saving and intelligent greenhouse for vegetable cultivation. Background Technology
[0002] Solar greenhouses are key facilities for the intensive cultivation of winter vegetable seeds and seedlings in northern my country. They rely on natural lighting and passive insulation to achieve off-season seedling cultivation and are widely used in facility agriculture. However, as modern agriculture develops towards high efficiency, intelligence, and low carbon, the energy consumption and safety issues of traditional seedling solar greenhouses under extreme weather conditions are becoming increasingly prominent.
[0003] During winter snowfall, large amounts of snow easily accumulate on the roof of greenhouses, increasing the roof load and potentially causing deformation, damage to the covering film, or even complete collapse, seriously threatening the safety of seedling production. Current technologies generally employ auxiliary heating devices inside greenhouses to address this snow accumulation problem. These devices raise the indoor temperature, allowing heat to be conducted to the roof for snow melting. However, this method has significant drawbacks. During operation, the heat required for snow melting must be supplied continuously at high power, and a large amount of heat is dissipated outwards through the greenhouse structure, resulting in extremely low heat utilization. This directly leads to a significant increase in greenhouse energy consumption during snowy weather, resulting in high operating costs. Furthermore, forced heating disrupts the stable temperature and humidity environment required for indoor seedling cultivation, easily causing seedling etiolation, scorching, and affecting seedling quality.
[0004] Therefore, an energy-saving and intelligent vegetable cultivation greenhouse is proposed to solve some of the problems existing in the above-mentioned technologies. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. In this invention, by designing the insulation quilt as a double-layer ring-shaped structure and matching it with a circulating transmission structure driven by a first roller shutter mechanism and a second roller shutter mechanism, the panel originally used for static insulation is transformed into a dynamically circulating conveyor belt. This allows the greenhouse to continuously and steadily transport snow from the roof to the sides of the greenhouse by simply driving the quilt to rotate in a circulating manner during snowy weather, without having to start a high-energy-consuming auxiliary heating device. This achieves physical snow removal, effectively avoiding the huge energy consumption of traditional electric snow melting, significantly reducing the operating cost of the greenhouse under extreme weather conditions, and meeting the needs of energy-saving and low-carbon modern agricultural development.
[0019] 2. In this invention, by setting up a sophisticated first control mechanism and a second control mechanism, the greenhouse has two working modes: a daily rolling / laying mode and a snow removal mode. In the snow removal mode, the control mechanism separates the connecting frame from the shaft, allowing it to idle and ensuring the stability of the quilt's cyclic snow removal. In the daily rolling / laying mode, the control mechanism locks the connecting frame to the shaft, enabling stable rolling and laying operations at the quilt's end position, effectively improving the intelligence and flexibility of the greenhouse in actual use.
[0020] 3. In this invention, by placing the first roller blind mechanism at a high position on the shed and connecting it with a pulley and platform that can move along the climbing pole, and using a cable for balance, a smooth and reliable operation of raising and lowering the upper part of the quilt can be achieved. At the same time, a second roller blind mechanism that can operate independently is provided, which can provide auxiliary power as a driven wheel during snow removal, and can also be used as another active roller blind point in daily life, realizing double-sided raising and lowering. This is beneficial to enhance the management flexibility in response to different weather conditions. Furthermore, by independently controlling the shed film through the film rolling mechanism, it can work in coordination with the raising and lowering of the quilt, which is beneficial to achieve precise and intelligent control of lighting, heat preservation, and ventilation.

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0047] Example: This example provides an energy-saving, intelligent vegetable cultivation greenhouse. See [link / reference]. Figure 1 - Figure 15 Specifically, the structure includes a canopy 1, with a canopy film 12 laid on its top. The top of the canopy 1 is equipped with a film rolling mechanism for taking up and taking down the canopy film 12. The film rolling mechanism includes a bearing 2 fixedly installed on the foundation on the front and rear sides of the canopy 1, and a telescopic rod 21 is hinged to the bearing 2. A support seat 22 is fixedly installed at the other end of the telescopic rod 21, and an electric film rolling device 23 is fixedly installed on the support seat 22. A film rolling rod 24 is fixedly connected between the drive shafts of the two electric film rolling devices 23. The side of the canopy film 12 closest to the first rolling mechanism is fixedly wound around the film rolling rod 24, and the side of the canopy film 12 closest to the second rolling mechanism is fixedly connected to the bottom edge of the canopy 1.
[0048] A cotton quilt 13 is laid on top of the canopy film 12, and the cotton quilt 13 is set as a double-layer ring-shaped structure. A climbing pole 3 is fixedly mounted above the center line of the canopy body 1, and a first trolley 31 is slidably connected to the climbing pole 3. A first connecting rod 32 is hinged to the first trolley 31, and a first platform 33 is hinged to the other end of the first connecting rod 32. A first motor 34 is fixedly mounted on the first platform 33. A first roller shutter mechanism acting on one end of the cotton quilt 13 is mounted on the first platform 33, and the first roller shutter mechanism includes a first bracket 4 fixedly mounted on the front and rear sides of the first platform 33. A longitudinally arranged first shaft 41 is rotatably mounted on the first bracket 4, and a first... The roller blind 42 has a first connecting frame 43 rotatably mounted on the first shaft 41, which is located on both the front and rear sides of the roller blind 42. A first clamping rod 44 parallel to the roller blind 42 is fixedly mounted on the first connecting frame 43. A first spline structure 45 is provided at one end of the first shaft 41 near the first platform 33. A first adjustment mechanism is provided between the first spline structure 45 and the first connecting frame 43. A second roller blind mechanism is provided at the other end of the quilt 13. The second roller blind mechanism includes a second shaft 61 rotatably mounted longitudinally. A second roller blind 62 is fixedly mounted on the second shaft 61. The quilt 13 is driven and sleeved between the first roller blind 42 and the second roller blind 62.
[0049] In this greenhouse, the first roller shutter mechanism enables the laying and rolling of the cotton quilt 13. During the rolling and laying of the cotton quilt 13, the first control mechanism controls the first shaft 41 and the first connecting frame 43 to be securely connected, ensuring that the first clamping rod 44 remains relatively stable relative to the first roller shutter roller 42. The first shaft 41 is connected to the drive shaft of the first motor 34. In this state, when the first roller shutter roller 42 is driven to rotate, it drives the first clamping rod 44 to rotate synchronously around the first roller shutter roller 42, allowing the first clamping rod 44 to clamp the end of the cotton quilt 13 in conjunction with the first roller shutter roller 42. By controlling the direction of rotation of the first shaft 41, the rolling and unrolling operations of the cotton quilt 13 can be controlled. In snowy weather, the cotton quilt 13 can be completely spread out on the greenhouse film 12. Above, the top of the greenhouse 1 is covered with insulation. At this time, the two ends of the cotton quilt 13 are driven and sleeved on the first roller 42 and the second roller 62. The first control mechanism can release the firm connection between the first shaft 41 and the first connecting frame 43, so that the first shaft 41 can rotate freely in the first connecting frame 43. In this state, when the first roller 42 is driven to rotate, it will not force the first clamp 44 to rotate synchronously. With the help of the rotation drive of the first roller 42, under the guidance of the second roller 62, the cotton quilt 13 can be driven to rotate and transport like a conveyor belt, transporting the snow that falls and accumulates on the top of the cotton quilt 13 to the side of the greenhouse, so that the snow falls on the side of the greenhouse, avoiding the continuous accumulation of snow on the top of the cotton quilt 13 and causing the greenhouse 1 to collapse.
[0050] In the specific implementation process, such as Figure 1 , Figure 7 , Figure 8 and Figure 11 As shown, the top of the greenhouse 1 is designed as a sloping structure, and a ventilation window 11 is provided at the highest point of the top of the greenhouse 1. The first roller shutter mechanism is located above the second roller shutter mechanism. In this greenhouse, the first roller shutter mechanism is used as the main structure for rolling up and laying the cotton quilt 13. The first roller shutter mechanism is located above the second roller shutter mechanism so that when the cotton quilt 13 is fully unfolded, the first roller shutter mechanism is in the upper position. With this structure, the cotton quilt 13 can be lifted from the top when the greenhouse is in use. In conjunction with the greenhouse, the greenhouse film 12 can be lifted from the top through the film rolling mechanism, so that the ventilation window 11 can be opened. This is beneficial for ventilation by opening the ventilation window 11 simultaneously while laying the cotton quilt 13.
[0051] In the specific implementation process, such as Figure 2 , Figure 9 and Figure 13 As shown, a winding wheel 35 is rotatably installed inside the first platform 33 and fixedly connected between the front and rear first shafts 41. A winding wheel 35 is also fixedly installed at the end of the first shaft 41 away from the first platform 33. A cable 36 is wound onto the winding wheel 35 and fixedly connected to it. The other end of the cable 36 passes over the top of the greenhouse body 1 and is fixedly connected to the foundation. In this greenhouse, when the quilt 13 is rolled up and laid by the first curtain mechanism, the rotation of the first shaft 41 can drive the winding wheel 35 to rotate synchronously, synchronously winding or releasing the cable 36. When the quilt 13 is rolled up by the first curtain mechanism... During the rolling process, the upper end of the quilt 13 gradually moves downwards as it is rolled up. During this process, the first trolley 31 slides down along the climbing pole 3. Simultaneously, the winding wheel 35 releases the cable 36 that is wound on it, ensuring the stability of the upper end of the quilt 13 during rolling. Conversely, when the quilt 13 is re-laid by the first rolling curtain mechanism, the upper end of the quilt 13 is gradually released and laid upwards on the top of the canopy film 12. Simultaneously, the winding wheel 35 winds up the cable 36, pulling the first rolling mechanism upwards, so that the first trolley 31 can slide upwards along the climbing pole 3, ensuring the stability of the upper end of the quilt 13 laid by the first rolling curtain mechanism.
[0052] In the specific implementation process, such as Figure 6 As shown, a uniformly distributed steel wire mesh is embedded inside the quilt 13. The cylindrical surfaces of the first roller 42 and the second roller 62 are fixedly equipped with uniformly distributed nail teeth. In this greenhouse, by embedding steel wire mesh inside the quilt 13, the structural strength of the quilt 13 can be effectively improved. By uniformly fixing the nail teeth on the first roller 42 and the second roller 62, the stability and smoothness of the quilt 13 when it is driven to rotate and be conveyed in snowy weather can be effectively improved by using the hooks of the nail teeth.
[0053] In the specific implementation process, such as Figure 2 , Figure 3 and Figure 13 As shown, the first control mechanism includes a first spline cylinder 5 slidably sleeved on the outside of the first spline structure 45, and a first spline tooth 51 fixedly installed at the end of the first spline cylinder 5 away from the first platform 33. A first spline groove 52 adapted to the first spline tooth 51 is opened in the first connecting frame 43. A first wheel cylinder 53 movably sleeved on the outside of the first spline cylinder 5 is fixedly installed on the side of the first connecting frame 43 near the first platform 33. A first rotating shaft 54 is rotatably mounted on the first bracket 4, and a first contact wheel 55 tightly fitted with the first wheel cylinder 53 is fixedly mounted on the first rotating shaft 54. A first contact wheel 55 sleeved on the outside of the first spline cylinder 5 is rotatably mounted on the first bracket 4. A first gear 56 is mounted on the side, and a second gear 57 that meshes with the first gear 56 is fixedly mounted on the first rotating shaft 54. A second spline tooth 58 is fixedly mounted on one end of the first spline cylinder 5 near the first platform 33. A second spline groove 59 that matches the second spline tooth 58 is opened on the inner side of the first gear 56. A first connecting plate 8 is rotatably connected to the first spline cylinder 5, and a first rack 81 that is parallel to the first spline cylinder 5 is fixedly mounted on the first connecting plate 8. A first gear disk 82 that meshes with the first rack 81 is rotatably mounted on the first platform 33. A third motor 83 for driving the first gear disk 82 to rotate is fixedly mounted on the first platform 33.
[0054] In this greenhouse, the state of the first control mechanism can be adjusted by controlling the position of the first spline cylinder 5. After the third motor 83 is powered on and started, it can drive the first gear plate 82 to rotate. With the meshing of the first gear plate 82 and the first rack 81, the position of the first connecting plate 8 can be adjusted, thereby realizing the adjustment of the position of the first spline cylinder 5. When the first spline cylinder 5 moves towards the first platform 33, the first spline tooth 51 will be inserted into the first spline groove 52. In this state, the first connecting frame 43 is connected and locked with the first shaft 41. When the first spline cylinder 5 moves away from the first platform 33, the first spline tooth 51 is disengaged from the first spline groove 52, so that the first connecting frame 43 and the first shaft 41 are connected in an idle manner.
[0055] While driving the quilt 13 to continuously rotate for snow removal, the first spline tooth 51 needs to remain disengaged from the first spline groove 52. In this state, the second spline tooth 58 is inserted into the second spline groove 59. During the rotation of the first shaft 41, it can not only drive the first roller blind 42 to rotate, but also drive the first gear 56 to rotate. With the help of the meshing and reversal of the first gear 56 and the second gear 57, the first contact wheel 55 is driven to reverse relative to the first roller blind 42. Under the contact friction between the first contact wheel 55 and the first wheel cylinder 53, the first wheel cylinder 53 is driven to further reverse, thereby causing the first contact wheel 55 to rotate. The first roller 53 drives the first clamping rod 44 fixed on the first connecting frame 43 to rotate around the first roller 42. By the movement of the first clamping rod 44 and the cotton quilt 13 being laid on top of the greenhouse film 12, the two layers of the cotton quilt 13 can be kept close together. When the rotation of the first clamping rod 44 is restricted, the first contact wheel 55 and the first roller 53 will slip and spin freely instead of getting stuck, thus ensuring the stability of the equipment operation. By actively applying a clamping tendency to the two layers of the cotton quilt 13, the heat preservation effect of the cotton quilt 13 when it is laid on top of the greenhouse film 12 can be guaranteed.
[0056] In the specific implementation process, such as Figure 1 , Figure 4 , Figure 5 and Figure 15 As shown, a second trolley 37 is slidably connected to the climbing rod 3, and a second connecting rod 38 is hinged to the second trolley 37. The other end of the second connecting rod 38 is hinged to a second platform 39, and a second motor 310 is fixedly installed on the second platform 39. The second roller blind mechanism is installed on the second platform 39. The second roller blind mechanism also includes a second bracket 6 fixedly installed on the front and rear sides of the second platform 39. A second shaft 61 is rotatably installed on the second bracket 6. A second connecting frame 63 is rotatably installed on the second shaft 61 and disposed on the front and rear sides of the second roller blind roller 62. A second clamping rod 64 is fixedly installed on the second connecting frame 63 and disposed parallel to the second roller blind roller 62. A second spline structure 65 is provided at the end of the second shaft 61 near the second platform 39, and a second adjustment mechanism is provided between the second spline structure 65 and the second connecting frame 63.
[0057] In this greenhouse, when snow is removed during snowy weather, the second motor 310 can be started to drive the second shaft 61 to rotate and drive the second roller 62 to rotate. In conjunction with the active rotation of the first roller 42, the cotton quilt 13 is driven to rotate simultaneously from both ends, ensuring stable power for the rotation of the cotton quilt 13 to remove snow. When the cotton quilt 13 is rotated in an auxiliary manner, the second connecting frame 63 and the second shaft 61 remain in an idle connection state.
[0058] In daily use, the lower end of the quilt 13 can also be rolled up and laid out through the second roller shutter mechanism. This operation is similar to the operating principle of the first roller shutter mechanism. During operation, the second connecting frame 63 and the second shaft 61 are kept in a synchronous locked state by the second control mechanism. The second clamping rod 64 cooperates with the second roller shutter roller 62 to clamp the lower end of the quilt 13. That is, the lower end of the quilt 13 is rolled up and laid out by means of the synchronous rotation of the second roller shutter roller 62 and the second clamping rod 64. With the above structural settings, the greenhouse can roll up and lay out the quilt 13 from both sides above at the same time, which is conducive to improving the flexibility of operation.
[0059] In the specific implementation process, such as Figure 4 , Figure 5 and Figure 15 As shown, the second control mechanism includes a second spline cylinder 7 slidably sleeved on the outside of the second spline structure 65, and a third spline tooth 71 fixedly installed at the end of the second spline cylinder 7 away from the second platform 39. A third spline groove 72 adapted to the third spline tooth 71 is opened in the second connecting frame 63. A second wheel cylinder 73 movably sleeved on the outside of the second spline cylinder 7 is fixedly installed on the side of the second connecting frame 63 near the second platform 39. A second rotating shaft 74 is rotatably mounted on the second bracket 6, and a second contact wheel 75 tightly fitted with the second wheel cylinder 73 is fixedly mounted on the second rotating shaft 74. A sleeved on the second spline structure 65 is rotatably mounted on the second bracket 6. A rotating wheel 76 is located on the outer side of the cylinder 7, and a transmission belt 77 is connected between the rotating wheel 76 and the second rotating shaft 74. A fourth spline tooth 78 is fixedly installed at one end of the second spline cylinder 7 near the second platform 39. A fourth spline groove 79 that matches the fourth spline tooth 78 is opened on the inner side of the rotating wheel 76. A second connecting plate 84 is rotatably connected to the second spline cylinder 7, and a second rack 85 that is parallel to the second spline cylinder 7 is fixedly installed on the second connecting plate 84. A second gear disk 86 that meshes with the second rack 85 is rotatably installed on the second platform 39. A fourth motor 87 for driving the second gear disk 86 to rotate is fixedly installed on the second platform 39.
[0060] In this greenhouse, the state of the first control mechanism can be adjusted by controlling the position of the second spline cylinder 7. After the fourth motor 87 is powered on and started, it can drive the second gear plate 86 to rotate. With the meshing of the second gear plate 86 and the second rack 85, the position of the second connecting plate 84 can be adjusted, thereby realizing the adjustment of the position of the second spline cylinder 7. When the second spline cylinder 7 moves towards the second platform 39, the third spline tooth 71 will be inserted into the third spline groove 72. In this state, the second connecting frame 63 is connected and locked to the second shaft 61. When the second spline cylinder 7 moves away from the second platform 39, the third spline tooth 71 is disengaged from the third spline groove 72, so that the second connecting frame 63 and the second shaft 61 are connected in an idle manner.
[0061] While driving the quilt 13 to continuously rotate for snow removal, the third spline tooth 71 needs to remain disengaged from the third spline groove 72. In this state, the fourth spline tooth 78 is inserted into the fourth spline groove 79. During the rotation of the second shaft 61, not only can the second roller shutter 62 rotate, but the rotating wheel 76 can also rotate. Through the transmission connection of the transmission belt 77, the second contact wheel 75 can be driven to rotate in the same direction. Under the contact friction between the second contact wheel 75 and the second wheel cylinder 73, the second wheel cylinder 73 can be driven to rotate in reverse, thereby causing the second wheel cylinder 73 to rotate in the opposite direction. The second clamping rod 64, fixed on the second connecting frame 63, rotates in the opposite direction around the second roller blind 62. By flipping the second clamping rod 64 upward, the two layers of the lower end of the quilt 13 can be kept close together. When the rotation of the second clamping rod 64 is restricted, the second contact wheel 75 and the second roller cylinder 73 will slip and spin freely instead of getting stuck, thus ensuring the stability of the equipment operation. By actively applying a clamping tendency to the two layers of the quilt 13, the heat preservation effect when the quilt 13 is laid below the top of the greenhouse film 12 can be guaranteed.
[0062] Specifically, the working principle of this invention is as follows:
[0063] In this greenhouse, during daily heat preservation, both the first and second roller curtain mechanisms are in "roll-up mode". The first motor 34 and the second motor 310 can work in coordination to drive the first roller curtain roller 42 and the second roller curtain roller 62 to rotate synchronously. Through the cooperation of the first clamping rod 44, the second clamping rod 64 and the corresponding first roller curtain roller 42 and second roller curtain roller 62, the cotton quilt 13 is tightly rolled up or spread out. During the laying, the cotton quilt 13 is laid flat on the greenhouse film 12 to form a uniform heat preservation layer. At this time, the ventilation window 11 can be opened part of the greenhouse film 12 for ventilation as needed after the cotton quilt 13 is rolled up to an appropriate position, through an independent film rolling mechanism, to achieve a balance between heat preservation and ventilation.
[0064] When it snows in winter, the system switches to the circulating snow removal mode. First, the third motor 83 drives the first gear disc 82, causing the first spline cylinder 5 to move away from the first platform 33. The first spline tooth 51 disengages from the first spline groove 52, while the second spline tooth 58 engages with the second spline groove 59. At this time, the first connecting frame 43 is unlocked from the first shaft 41. Similarly, the fourth motor 87 controls the movement of the second spline cylinder 7, unlocking the second connecting frame 63 from the second shaft 61. Then, the first motor 34 and the second motor 310 are started, driving the first roller blind roller 42 and the second roller blind roller 62 to rotate in the same direction. Since the connecting frame is idling, the rotation of the first roller blind roller 42 and the second roller blind roller 62 is no longer strong. Instead of rotating the corresponding first clamping rod 44 and second clamping rod 64, the blanket 13 is driven to rotate in a circular motion like a conveyor belt. Snow falls onto the rotating blanket 13. As the blanket 13 moves from the side of the first roller shutter mechanism at a high position on the roof to the side of the second roller shutter mechanism at a low position, it is eventually transported to the side edge of the greenhouse and thrown off. During this process, the friction transmission between the first contact wheel 55 and the first wheel cylinder 53, and between the second contact wheel 75 and the second wheel cylinder 73, will drive the first clamping rod 44 and the second clamping rod 64 to swing slightly, continuously generating a smoothing and pressing auxiliary force on the blanket 13, ensuring that the blanket 13 remains flat and tight during rotation. This optimizes the snow removal effect and maintains the heat preservation performance of the interior of the lower greenhouse body 1.
