Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically a double-layer film temperature, light and humidity regulating greenhouse. Background Technology

[0002] Double-layer film greenhouses are agricultural facilities that form an air insulation layer through two layers of covering materials. They combine heat preservation, energy saving, and stress resistance, making them suitable for crop cultivation under various climatic conditions. They feature a two-layer frame design: the outer layer is covered with a high-transmittance film, while the inner layer can be electrically rolled up. This enhances light transmittance during the day and improves heat preservation when closed at night. They also have strong wind and snow resistance, making them suitable for cold northern regions.

[0003] The patent publication number CN213881088U discloses a double-layer film insulation greenhouse, which includes a frame composed of an inner arch beam and an outer arch beam installed sequentially on the top of several columns. Both the inner arch beam and the outer arch beam are covered with plastic film. A first mounting frame is installed on the outer arch beam, and a second mounting frame corresponding to the first mounting frame is installed on the inner arch beam. A ventilation pipe is installed between the first mounting frame and the second mounting frame, and a fan is installed on the ventilation pipe.

[0004] As shown in the above technology, double-layer film greenhouses are often used for heat preservation during planting. However, due to the presence of double film, the light transmittance inside the greenhouse is reduced, making it difficult to achieve a balance between heat preservation and light transmittance, thus preventing the planted species from obtaining a better growth environment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-layer film temperature, light, and humidity regulating greenhouse, which solves the problem of insufficient balance between heat preservation and light transmission control in existing double-layer film temperature, light, and humidity regulating greenhouses.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-layer film temperature, light and humidity regulating greenhouse includes multiple arch beams and an outer film, with support frame assemblies provided on both sides of the multiple arch beams, and opening and closing components provided on the arch beams;

[0007] The opening and closing assembly has a symmetrical structure and includes two sliding sleeves and multiple rings. Both sliding sleeves are fitted onto the outside of the arch beam. Each sliding sleeve and ring is equipped with a fixing component for fixing the outer membrane. A support plate is fixedly connected to one side of the sliding sleeve, and a drive motor is fixedly connected to the inner side of the support plate. The output end of the drive motor is fixedly connected to a drive gear. Multiple toothed grooves are equally spaced on the inner side of the frontmost and rearmost arch beams, forming an arc-shaped rack. The drive gear meshes with the toothed grooves for transmission.

[0008] Preferably, the plurality of rings are respectively disposed on the outside of the arch beam. The surface of the frontmost and rearmost arch beams are each provided with a ring, and the surfaces of the remaining arch beams are provided with three rings at equal intervals along their arc direction. The ring located in the middle of the surface of the arch beam is fixedly connected to the surface of its corresponding arch beam, and the remaining rings are only fitted on the outside of the arch beam.

[0009] Preferably, the fixing component includes a plug rod, which is fixedly connected to the top of the ring, and the surface of the plug rod is provided with two L-shaped limiting grooves on the left and right sides.

[0010] Preferably, the fixing component further includes a pressure ring, which is sleeved on the outside of the insertion rod. A limit spring is fixedly connected to the top of the pressure ring, and a locking ring is fixedly connected to the other end of the limit spring. Two mounting blocks that mate with the L-shaped limit groove are fixedly connected to the inner surface of the locking ring.

[0011] Preferably, the support frame assembly includes two mounting frames, left and right, with drainage grooves on the top of each mounting frame, multiple support legs fixedly connected to the bottom of each mounting frame, and sliding grooves on opposite sides of each mounting frame.

[0012] Preferably, the inner surface of the slide groove is slidably connected with multiple plug sleeves, and a nut is fixedly connected to one end of the plug sleeve located inside the slide groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This double-layer film temperature, light, and humidity regulating greenhouse offers two technical solutions:

[0026] The first implementation method includes multiple arch beams 1 and an outer membrane 2. Support frame assemblies 3 are provided on both sides of the multiple arch beams 1. Opening and closing assemblies 4 are provided on the arch beams 1. An inner membrane is provided on the inner side of the multiple arch beams 1, and the inner membrane is staggered from the opening and closing assemblies 4 when it is laid.

[0027] The opening and closing assembly 4 has a left-right symmetrical structure. The opening and closing assembly 4 includes two left and right sliding sleeves 41 and multiple rings 42. Both sliding sleeves 41 are sleeved on the outside of the arch beam 1. Both the sliding sleeves 41 and the rings 42 are provided with fixing components 43, and the fixing components 43 are used to fix the outer membrane 2. A support plate 44 is fixedly connected to one side of the sliding sleeve 41. A drive motor 45 is fixedly connected to the inner side of the support plate 44, and a drive gear 46 is fixedly connected to the output end of the drive motor 45. Multiple tooth grooves 47 are equally spaced on the inner side of the frontmost and rearmost arch beam 1, and the multiple tooth grooves 47 form an arc-shaped rack. The drive gear 46 meshes with the tooth grooves 47 for transmission.

[0028] Multiple rings 42 are respectively set on the outside of the arch beam 1. The surface of the frontmost and rearmost arch beam 1 is each provided with a ring 42. The surface of the remaining arch beam 1 is provided with three rings 42 at equal intervals along its arc direction. The ring 42 located in the middle of the surface of the arch beam 1 is fixedly connected to the surface of its corresponding arch beam 1. The remaining rings 42 are only fitted on the outside of the arch beam 1.

[0029] The support frame assembly 3 includes two mounting brackets 31, one on the left and one on the right. Each mounting bracket 31 has a drainage groove 32 on its top and multiple support legs 33 fixedly connected to its bottom. Each mounting bracket 31 has a sliding groove 34 on its opposite side. Multiple plug sleeves 35 are slidably connected to the inner surface of each sliding groove 34. A nut 36 is fixedly connected to one end of each plug sleeve 35 located inside the sliding groove 34. An arch beam 1 is inserted into the plug sleeve 35. A bolt 37 is inserted into one side of the plug sleeve 35 and passes through the plug sleeve 35 to the arch beam 1 and is threadedly connected to the nut 36.

[0030] During the planting process, the outer membrane is unfolded or folded by the opening and closing component 4. When light is needed, the outer membrane 2 is folded to allow better light to shine on it, and unfolded when heat preservation is needed, providing a better planting environment for the plants and improving the practicality of the device.

[0031] The second embodiment differs from the first embodiment in that: the fixing component 43 includes a rod 431, which is fixedly connected to the top of the ring 42. The surface of the rod 431 is provided with two L-shaped limiting grooves 432. The fixing component 43 also includes a pressure ring 433, which is sleeved on the outside of the rod 431. A limiting spring 434 is fixedly connected to the top of the pressure ring 433. A locking ring 435 is fixedly connected to the other end of the limiting spring 434. Two mounting blocks 436 that cooperate with the L-shaped limiting grooves 432 are fixedly connected to the inner surface of the locking ring 435.

[0032] The outer membrane 2 is connected to the arch beam 1 through the fixing component 43 and the opening and closing component 4. When fixing, simply insert the rod 431 through the outer membrane 2, and fix it quickly through the cooperation of the pressure ring 433, the limit spring 434 and the locking ring 435, which improves the convenience of using the device.

[0033] In use, the outer film 2 is laid flat on the outside of multiple arch beams 1, and multiple insert rods 431 penetrate the outer film 2. At this time, the pressure ring 433 is fitted onto the outside of the insert rod 431, so that the mounting block 436 is aligned with the L-shaped limiting groove 432, and the locking ring 435 is pressed down. When the mounting block 436 moves to the bottom of the L-shaped limiting groove 432, the locking ring 435 is rotated, thereby limiting the mounting block 436 through the lateral part of the insert rod 431. At this time, the outer film 2 is fixed. When stronger light is needed, multiple drive motors 45 are started. Two drive motors 45 on the same side start and rotate in opposite directions. Through the cooperation of the drive gear 46 and the arc rack, the sliding sleeve 41 moves, thereby causing the outer film 2 to fold and shrink. At this time, the greenhouse is filled with stronger light.
