Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and in particular to a sleeve-type lightweight flame-retardant and heat-insulating curtain. Background Technology

[0002] A shading curtain is a fabric used to block sunlight, widely used in outdoor and indoor locations. It is typically a composite plastic woven mesh, available in several density specifications with varying shading rates. Its main uses are sunshade and rain protection in summer, and heat insulation in winter. A common application is in greenhouses in agriculture, where a shading curtain made of polyethylene film or non-woven fabric is placed over the greenhouse frame to create a greenhouse effect, thereby promoting early maturity and increased yields for crops inside. Currently, greenhouse shading curtains not only need to provide sunshade and heat insulation, but also require a stable connection structure to adapt to complex climates. They also need to be easy to install and disassemble, and can be opened and closed during day and night cycles to accommodate temperature changes. For example, Chinese patent document CN202022816794.2 discloses an agricultural greenhouse, including a greenhouse frame, water pipes, sprinkler heads, and pins. Fixed frames are fixedly installed adjacent to each other on the front and rear sides of the top of the greenhouse frame. Servo motors are symmetrically arranged on the inner walls of both sides of the fixed frames. The output ends of the servo motors rotate horizontally towards the center of the fixed frames and are connected to a rotating shaft. A shading curtain is wound up on the rotating shaft. The aforementioned patent utilizes a servo motor, a rotating shaft, and a shading curtain. When the plant species in the greenhouse are changed to those that prefer shade, darkness, and moisture, simply activating the servo motor drives the rotating shaft, which then slowly lowers the shading curtain to cover the entire greenhouse, plunging it into darkness. This achieves stable opening and closing of the curtain, adapting to various temperature changes. However, due to the limited diameter of the rotating shaft, the patent's method of winding the curtain around it has a limited area that can be rolled up. Furthermore, for greenhouses hundreds of meters long, installing numerous servo motors would be prohibitively expensive, and frequent winding and rolling would severely impact the curtain's lifespan.

[0003] Therefore, it is necessary for those skilled in the art to provide a flexible, lightweight, flame-retardant, and heat-insulating curtain that is easy to install on a greenhouse and open and close, ensures the stability of the connection, and reduces costs. Utility Model Content

[0004] The purpose of this utility model is to provide a lightweight, flame-retardant, and heat-insulating curtain that can be fitted over a single layer, in order to solve the technical problems in the prior art where curtains on greenhouses are difficult to open and close, cannot adapt to complex temperature conditions, and affect crop growth.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sleeve-type lightweight flame-retardant heat-insulating curtain, including a curtain body and a support frame. The curtain body is installed between two adjacent supports and the curtain body can be folded. The curtain body has a multi-layer composite structure with grooves formed on it. The curtain body is made of soft material and includes, from the outside to the inside, an outer heat-insulating layer, a mixed fiber layer, a woven mesh, a heat-insulating layer, and an inner heat-insulating layer. The support frame has a strip-shaped structure and includes a support part and mating parts symmetrically arranged on both sides of the support part. The side of the curtain body is mated and connected to the mating parts and can be slidably connected.

[0006] Furthermore, the curtain body has a mating block on its side, which is connected to the mating part on the bracket. The cross-section of the mating part is arc-shaped, and the mating block has an arc-shaped hole with the same cross-sectional structure as the mating part. The mating block is slidably mounted on the mating part.

[0007] Furthermore, the outer insulation layer, the mixed fiber layer, the woven mesh, the thermal insulation layer, and the inner insulation layer are stacked on top of each other in sequence, with the outer insulation layer facing the outside atmosphere.

[0008] Furthermore, the outer insulation layer is made of nano-aerogel felt, and the inner insulation layer is made of ceramic fiber, with the inner insulation layer located inside the curtain body.

[0009] Furthermore, the mixed fiber layer is made of a blend of polyester fiber and nylon fiber, the woven mesh is made of carbon fiber filaments, part of the woven mesh is embedded inside the mixed fiber layer, and the other part of the woven mesh is embedded inside the insulation layer, which is made of duck down.

[0010] Furthermore, the mating blocks are provided in multiples, and a groove is provided between one mating block and an adjacent mating block, and one mating block can be abutted against an adjacent mating block.

[0011] Furthermore, there are at least two grooves between a mating block and an adjacent mating block, and a gap is provided between a mating block and an adjacent mating block.

[0012] Furthermore, the groove extends from one side of the curtain body to the other side, and the cross-section of the curtain body perpendicular to the direction of the groove is wavy.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a foldable curtain body to achieve its rolling. When the temperature inside the greenhouse is too high, the curtain body is contracted, thereby reducing the laying area of ​​the curtain body and realizing folding and rolling. When the temperature inside the greenhouse is too low, the curtain body is extended, thereby increasing the laying area of ​​the curtain body and realizing laying. This greatly improves the convenience of use. At the same time, compared with the existing technology that uses a motor to drive the rolling, this utility model can retract using the structure of the curtain body itself, which greatly reduces the production cost and is easy to operate.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figure 1 , Figure 2 This utility model provides a lightweight, flame-retardant, and heat-insulating curtain, comprising a curtain body 10 and a support frame 20. The curtain body 10 is detachably connected to the support frame 20, and the curtain body 10 forms a greenhouse. Multiple supports 20 are provided and evenly distributed. The curtain body 10 is installed between two adjacent supports 20 and is foldable. The support frame 20 supports the curtain body 10, allowing it to unfold or compress and maintain a stable shape. The support frame 20 can be made of metal, such as aluminum alloy, which has high strength and stability.

[0021] Further, please refer to Figure 3The curtain body 10 has a multi-layer composite structure. From the outside to the inside, the curtain body 10 includes an outer insulation layer 11, a mixed fiber layer 13, a woven mesh 14, a heat insulation layer 15, and an inner insulation layer 12. The outer insulation layer 11, the mixed fiber layer 13, the woven mesh 14, the heat insulation layer 15, and the inner insulation layer 12 are stacked on top of each other in sequence. The outer insulation layer 11 faces the outside atmosphere, and the inner insulation layer 12 abuts against the top of the greenhouse.

[0022] Specifically, the outer insulation layer 11 is made of nano-aerogel felt, which has an extremely low thermal conductivity and serves as the outermost protective layer of the curtain body 10. It can effectively isolate the invasion of external hot and cold air, greatly reduce the heat conduction rate, and provide insulation for the greenhouse enclosed by the curtain body 10.

[0023] The inner insulation layer 12 is made of ceramic fiber and is located inside the curtain body 10, forming a double insulation barrier with the outer insulation layer 11. Simultaneously, the inner insulation layer 12 uses a high-efficiency thermal insulation material made of ceramic fiber, which can further prevent the loss of internal heat and ensure the temperature stability of the greenhouse.

[0024] The mixed fiber layer 13 is made of a blend of polyester and nylon fibers. By using a combination of multiple high-strength fibers, the curtain body 10 has excellent flexibility and high strength, enabling it to maintain good physical properties even in complex environments. At the same time, it can stretch and deform, effectively improving the curtain's durability and tear resistance.

[0025] The woven mesh 14 is made of carbon fiber filaments. Part of the woven mesh 14 is embedded inside the mixed fiber layer 13, and another part is embedded inside the thermal insulation layer 15. The woven mesh 14 is made of high-strength carbon fiber filaments, providing strong structural support for the curtain and significantly enhancing the overall strength and stability of the curtain, enabling it to withstand greater external pulling forces. At the same time, the woven mesh 14 integrates the thermal insulation layer 15 and the mixed fiber layer 13 into one unit, ensuring structural strength, preventing delamination between the layered curtain body 10, and improving stability in use.

[0026] The insulation layer 15 is made of duck down. The numerous tiny air gaps formed by the duck down in the insulation layer 15 not only greatly improve the heat preservation effect, but also have excellent energy absorption effect, which greatly improves the stability of use and makes it suitable for a variety of harsh environments.

[0027] Please see Figure 3 , Figure 4The screen body 10 is folded, and grooves 17 are formed on the screen body 10. The multi-layered composite structure of the screen body 10 is made of soft material, so that the screen body 10 can be contracted or unfolded between the supports 20. The grooves 17 extend from one side of the screen body 10 to the other side, and the cross-section of the screen body 10 perpendicular to the direction of the grooves 17 is wavy, so as to ensure that the screen body 10 has sufficient folding space during the folding process.

[0028] Compared to existing technologies that use a looping method to roll up the curtain, this invention uses a foldable curtain body 10 to achieve this. When the temperature inside the greenhouse is too high, the curtain body 10 is retracted, thereby reducing the laying area of ​​the curtain body 10 and achieving folding and rolling. When the temperature inside the greenhouse is too low, the curtain body 10 is extended, thereby increasing the laying area of ​​the curtain body 10 and achieving laying. This greatly improves the ease of use. At the same time, compared to existing technologies that use a motor to drive the rolling, this invention can retract using the structure of the curtain body 10 itself, which greatly reduces production costs and facilitates operation.

[0029] Further, please refer to Figure 3 , Figure 4 The bracket 20 has a strip-shaped structure and includes a support part 21 and a mating part 22 symmetrically arranged on both sides of the support part 21. The side of the curtain body 10 is mated and connected to the mating part 22.

[0030] Specifically, the curtain body 10 has a mating block 16 on its side. The mating block 16 is mated to the mating part 22 on the bracket 20. The cross-section of the mating part 22 is arc-shaped. The mating block 16 has an arc-shaped hole (not shown in the figure) with the same cross-sectional structure as the mating part 22. This allows the mating block 16 to be slidably mounted on the mating part 22. In use, multiple mating blocks 16 are fixedly connected to the side of the curtain body 10, and the mating blocks 16 are driven to move, thereby driving the curtain body 10 to compress and unfold on the bracket 20.

[0031] This utility model uses a bracket 20 as the supporting frame for the curtain, and its structural design fully considers the convenience of installation and the stability of use. It is made of lightweight, high-strength aluminum alloy, which combines the advantages of light weight, corrosion resistance, and high strength. The bracket 20 has a modular and detachable structural design, and the curtain body 10 is assembled via a connecting device (not shown in the figure), facilitating its unfolding and retraction. When used simultaneously, multiple curtain bodies 10 are independently arranged, allowing for partial opening in large greenhouses, greatly improving ease of use.

[0032] In this embodiment, multiple mating blocks 16 are provided. Each mating block 16 has a groove 17 between it and an adjacent mating block 16, and the mating blocks 16 can abut against each other. Thus, when the curtain body 10 retracts, two adjacent mating blocks 16 abut together, and the groove 17 between the two adjacent mating blocks 16 closes under the action of the adjacent mating blocks 16. This ensures that the curtain body 10 maintains a stable connection structure even in the retracted state, guaranteeing operational stability.

[0033] In another embodiment, at least two grooves 17 are provided between a mating block 16 and an adjacent mating block 16, and a gap is provided between a mating block 16 and an adjacent mating block 16, so that when the curtain body 10 shrinks, the two adjacent mating blocks 16 move closer to each other, and the multiple grooves 17 located between the two adjacent mating blocks 16 close under the action of the adjacent mating blocks 16, thereby realizing shrinkage and reducing the number of mating blocks 16, thereby reducing costs.

[0034] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
