Description

Technical Field

[0001] This utility model relates to the field of agricultural insulation covering materials and equipment, and in particular to a traction telescopic greenhouse folding insulation blanket. Background Technology

[0002] In the cultivation of flowers, fruits, vegetables, medicinal herbs, and other plants, different plants have different requirements for sunlight and heat preservation, and the amount of sunlight they need each day also varies. This necessitates the installation of shading and heat preservation equipment at the planting site to adjust the duration and range of sunlight exposure according to the plants' needs. This equipment can be deployed and retracted. While conventional retractable plant planting heat preservation structures facilitate the deployment and retraction of shading blankets, their lifespan gradually decreases due to prolonged exposure to sunlight and humidity outdoors, requiring periodic replacement. Furthermore, the installation and disassembly of existing shading blankets are cumbersome, hindering quick replacement and increasing the workload for maintenance personnel.

[0003] Existing sunshade and heat-insulating sheds generally use either rack and pinion systems or steel cables for installation, with metal poles or ropes typically used for securing them. This installation method has several drawbacks: it requires numerous installation components and materials, on-site installation is labor-intensive and time-consuming, requires professional installation, and is quite cumbersome. Furthermore, it is not standardized, leading to a high failure rate later on, and the supporting materials are prone to corrosion and aging, requiring regular repairs and replacements, thus increasing operating costs.

[0004] In addition, thermal blankets are mainly used in winter to keep flowers, fruits, vegetables, medicinal herbs and other plants in greenhouses warm during the winter. After the temperature rises, they need to be folded up. If thermal blankets are not folded up evenly, they may take up a lot of space, block the light and affect the growth of plants.

[0005] Patent CN215380311U discloses a folding insulation blanket. In this design, a traction rope is fixed to the top of the blanket with evenly distributed polyethylene strips. Hooks are installed on these polyethylene strips, and these hooks are movably fitted onto the outside of the hanging line. Multiple hooks are required on each polyethylene strip for traction support, and multiple hooks are attached to each hanging line. The excessive number of hooks results in significant accumulated frictional resistance between the hooks and the hanging line, severely impacting usability. Furthermore, because the polyethylene strips are externally connected to the insulation blanket, their traction capacity is insufficient, necessitating the installation of additional hooks in the middle for auxiliary traction. This addition of hooks inevitably increases the number of traction components, making the entire greenhouse structure more complex, increasing costs, and making subsequent maintenance more troublesome. Utility Model Content

[0006] This utility model proposes a traction-retractable greenhouse folding insulation blanket, which can be easily unfolded and retracted, occupies little space, and has a simple structure that is not easily damaged.

[0007] The technical solution of this utility model is implemented as follows: a traction-retractable greenhouse folding insulation blanket includes a support layer that provides support and traction, an insulation layer composed of insulation material, and a clamping layer that, together with the support layer, holds the insulation layer; the insulation blanket has an accordion-style folding structure, and the insulation blanket is provided with traction parts for easy traction and folding creases at intervals; the traction parts are several traction ropes provided in the support layer for traction, and each traction rope is arranged parallel to the others at equal distances; the support layer is a woven mesh fabric with traction ropes, and the traction ropes are woven into the mesh fabric and parallel to the direction of the narrow side; the main body of the traction ropes is woven into the support layer together with the webbing, and the two ends of the traction ropes extend out of the support layer and are connected to the traction device.

[0008] Preferably, the traction device includes a slide rail, rollers and a traction motor, with both ends of the traction rope connected to the rollers, and the traction motor driving the rollers to move on the slide rail.

[0009] Preferably, the crease is a strip-shaped folded area on the support layer, insulation layer and clamping layer, with the crease and the traction rope being arranged alternately and parallelly at equal distances on the insulation blanket.

[0010] Preferably, the insulation blanket has a thinner section at the fold of the support layer, with a thickness and hardness less than other parts, and is distributed between the two traction ropes.

[0011] Preferably, the support layer is located on the top layer, the insulation layer is located in the middle layer, and the clamping layer is located on the bottom layer. The support layer and the clamping layer are stitched together to wrap the insulation layer. The crease portion is a flexible part at the corresponding position of the insulation layer and the clamping layer, and the filling thickness of the insulation layer at the crease portion is lower than that of other parts.

[0012] Preferably, the support layer is a weather-resistant textile mesh material, the insulation layer is a flexible insulation filling material layer, and the clamping layer is a flexible fabric of polyethylene textile mesh.

[0013] Preferably, the traction rope is connected to a vertically arranged lifting device in the middle. There are one or more lifting devices, the lower end of which is fixedly connected to the traction rope, and the upper end of which is connected to a traction device.

[0014] Preferably, the lifting device includes a traction rod and a hook, with the lower end of the hook directly connected to the traction rope. A short section of the traction rope at the position corresponding to the hook is bent and protrudes from the support layer, and the hook is hung on the bent section of the traction rope.

[0015] Preferably, the traction device above the hoisting device includes a slide rail, rollers, and a traction motor. The top of the traction rod is connected to the rollers, and the traction motor drives the rollers to move along the slide rail.

[0016] Compared with existing technologies, the advantages of this invention are as follows: the rope-like traction straps are directly embedded into the support layer of the thermal insulation blanket, becoming part of the blanket itself. No additional assembly is required for use; it can be used immediately without additional connectors, reducing friction, lowering the failure rate, and making it less prone to damage, thus extending its service life. The entire support layer, along with the insulation layer and clamping layer, can be contracted and unfolded by the traction straps. The parallel and equidistant arrangement of the traction straps allows for more even contraction and folding of the thermal insulation blanket, resulting in a compact size when folded, saving space and offering both aesthetics and practicality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0025] Example: See Figure 1 and Figure 2 A traction-type retractable greenhouse folding insulation blanket includes a support layer 1 for support and traction, an insulation layer 2 composed of insulation material, and a clamping layer 3 that, together with the support layer 1, holds the insulation layer 2. The insulation blanket has an accordion-style folding structure, with traction parts and folding creases 12 spaced apart on the blanket for easy traction. The traction parts consist of several traction ropes 11 installed inside the support layer 1, with each traction rope 11 arranged parallel and equidistant from the others. Both ends of the traction ropes 11 extend to the outside of the support layer 1 and connect to an external traction device. The rope-like traction ropes 11 are directly embedded into the support layer 1, becoming part of the support layer 1. No additional assembly is required during use, and the absence of extra connectors reduces the risk of damage, lowers the failure rate, and extends the service life. The entire support layer 1, insulation layer 2 and clamping layer 3 can be contracted and unfolded by the traction of the traction rope 11. The traction ropes 11 are set at equal distances and in parallel, which allows the insulation to be contracted and folded more evenly. After being folded up, the volume is small, does not take up too much space, and is both beautiful and practical.

[0026] The traction rope 11 in this application is directly woven into the support layer 1, forming an integral whole with the support layer 1. There is no special connecting part, the force is more even, and the metal connecting parts are reduced, making it less prone to corrosion. There is no need to set up curtain lines, the structure is simple, the traction friction resistance is small, and the failure and damage rate is low.

[0027] Thermal insulation blankets are mainly used in winter to keep flowers, fruits, vegetables, medicinal herbs and other plants in greenhouses warm during the winter. They need to be folded up after the temperature rises. The thermal insulation blankets using this solution are easy to fold and have a small volume when folded. They do not take up too much space when not in use, so they do not block light and do not affect the photosynthesis and growth of plants.

[0028] The crease 12 is a strip-shaped folded area on the support layer 1, insulation layer 2, and clamping layer 3, with flexible treatment applied at corresponding positions. The crease 12 and the traction rope 11 are alternately and parallelly arranged at equal intervals on the insulation blanket. The crease 12 is inside the insulation blanket and has the same width as the insulation blanket, and its thickness is less than the thickness of other parts of the insulation blanket. Because the crease 12 is thin, when the traction rope 11 contracts, the insulation blanket will preferentially bend at its weakest point under the influence of gravity. Furthermore, the crease 12 is located in the middle of the two traction ropes 11, and the combined effect of these two factors naturally results in the folded area.

[0029] The support layer 1 is a woven mesh fabric with traction ropes. The traction ropes 11 are woven into the mesh fabric and are parallel to one of its edges. The traction ropes 11 can be arranged along the length or width direction as needed. The folded portion 12 is also arranged in the length or width direction, consistent with the traction ropes 11. The main body of the traction ropes 11 is woven into the support layer 1 together with the webbing. The insulation blanket is thinned at the folded portion of the support layer 1, with a thickness and stiffness less than other parts. It is distributed between the two traction ropes 11 to facilitate folding when the traction ropes 11 are gathered.

[0030] For example, the traction rope 11 and the folded part 12 are set along the length of the insulation quilt and perpendicular to the width of the insulation quilt. The entire insulation quilt only needs a few traction ropes 11 to achieve traction and folding.

[0031] Figure 3 As shown, a vertically arranged lifting device 4 is connected to the middle of the traction rope 11. There are one or more lifting devices 4. The lower end of the lifting device 4 is fixedly connected to the traction rope 11, and the upper end of the lifting device 4 is connected to a sliding device. If the length of the insulation blanket is large, the middle position of the insulation blanket may sink due to gravity. Therefore, it is necessary to connect a vertically arranged lifting device 4 to the middle of the traction rope 11. There are one or more lifting devices 4, which are determined according to the actual length of the support layer 1 and the weight of the entire insulation blanket. The lifting device 4 can be a rope or a rod. Its lower end is fixedly connected to the traction rope 11, and its upper end is connected to the sliding device. The connection method can be a lifting ring, a slide rail 5, or other sliding methods.

[0032] The support layer 1 is located on the top layer, the insulation layer 2 is located in the middle, and the clamping layer 3 is located on the bottom layer. The support layer 1 and the clamping layer 3 are sewn together to wrap the insulation layer 2. The folded portion 12 at the corresponding position of the insulation layer 2 and the clamping layer 3 is a flexible part, and the filling thickness of the insulation layer 2 at the folded portion 12 is lower than that of other parts. The support layer 1 is a weather-resistant textile mesh material, the insulation layer 2 is a cotton, sponge, or fiber filling layer, and the clamping layer 3 is polyethylene or flexible mesh fabric. The insulation layer 2 and the clamping layer 3 also have folded structures at the corresponding position of the folded portion 12 of the support layer 1. The folded structures can make the insulation layer 2 thinner at this position, and then the clamping layer 3 and the insulation layer 2 are fixed at this position by sewing to achieve a folded effect.

[0033] The rope-like traction strap 11 is directly embedded into the support layer 1, becoming part of the support layer 1. It can be used without additional assembly, and without additional connectors, it is less prone to damage, extending its service life. The entire support layer 1, insulation layer 2, and clamping layer 3 can be contracted and unfolded by the traction of the traction strap 11. The traction straps 11 are arranged parallel at equal distances, allowing the insulation to contract and fold more evenly.

[0034] The width of thermal insulation blankets is generally limited to 1-10 meters, while the length is not limited and can be extended according to actual needs. The crease spacing can be adjusted according to actual needs, and the crease distance between two creases can be set between 10 cm and 100 cm.

[0035] The traction rope 11 of the support layer 1 is woven into the mesh surface with a rope similar to the longitudinal webbing, such as a strong and durable parachute rope, braided rope, plastic rope, or steel rope, which facilitates traction and stretching. The webbing at the crease 12 position is thinner and has lower strength than the longitudinal webbing, making it easier to bend.

[0036] The webbing of the support layer 1 may also include webbing A and webbing B that intersect obliquely with the length direction. The traction rope 11 and the crease portion 12 are obliquely staggered with webbing A and webbing B, and the thickness at the intersection of webbing A and webbing B with the crease portion 12 is lower than the thickness at other locations.

[0037] The traction device includes a slide rail 5, rollers and a traction motor. The two ends of the traction rope 11 are connected to the rollers, and the traction motor drives the rollers to move on the slide rail 5.

[0038] A vertically arranged lifting device 4 is connected to the middle of the traction rope 11. There are one or more lifting devices 4, with the lower end fixedly connected to the traction rope 11 and the upper end connected to a traction device. The lifting device 4 includes a traction rod 41 and a hook 42. The lower end of the hook 42 is directly connected to the traction rope 11. A short section of the traction rope 11 at the position corresponding to the hook 42 bends and protrudes from the support layer 1, and the hook 42 hangs on the bent section of the traction rope 11. Preferably, the lifting device 4 includes a traction device slide rail 5, rollers, and a traction motor. The top end of the traction rod 41 is connected to the rollers, and the traction motor drives the rollers to move along the slide rail 5.

[0039] When the width of the thermal insulation quilt is small, only the traction devices at both ends need to pull the traction rope 11, and the tension of the traction rope 11 is sufficient to bear the weight of the entire thermal insulation quilt.

[0040] like Figure 3 , Figure 4 As shown, when the insulation blanket is wide, its weight increases, requiring the addition of a lifting device 4 in the middle. The traction device above the lifting device 4 is the same as the traction devices at both ends of the traction rope 11. The lower end of the lifting device 4 is directly connected to the protruding bend of the traction rope 11 of the support layer 11, eliminating the need for additional lifting rings, reducing the installation of spare parts, and thus reducing the failure rate and frequency of maintenance and replacement. The use of traction devices at the top and both sides allows for simultaneous traction of the traction rope 11 and even the entire insulation blanket, ensuring smooth operation of the insulation blanket.

[0041] In this application, the traction endpoints are minimized and optimized, and all are active traction driven by the power source, without the installation of passive traction components such as curtain hanging lines. This reduces frictional resistance, making the operation of the entire insulation blanket smoother, avoiding malfunctions, and ensuring service life.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
