Description

Technical Field

[0001] The invention relates to the field of novel heat preservation technology for solar greenhouses in facility agriculture, and in particular to a design of an inflatable heat preservation blanket for a solar greenhouse and a manufacturing method thereof. Background Art

[0002] Greenhouse insulation quilts are mainly used for nighttime heat preservation in greenhouses. With the rapid development of greenhouse planting industry, insulation quilts are gradually being accepted by farmers. As the "cotton-padded clothes" of greenhouses, insulation quilts not only increase the temperature of greenhouses, but also contribute to enriching people's dining tables in winter. Traditional solar greenhouse insulation quilts are mainly made of materials such as cattail, straw, recycled cotton or foam plastic, which are sewn or bonded to form a 2cm-5cm thick quilt. The disadvantage of insulation quilts made of cattail, straw, and recycled cotton is that they are very heavy. Once soaked by rain and snow, they will increase the weight and reduce the thermal insulation performance. In addition, they will seriously pollute the greenhouse film and easily reduce the light transmittance of the film. Insulation quilts made of foam plastic have the disadvantages of weak wind resistance and waste pollution to the environment.

[0003] The thermal insulation blankets of solar greenhouses are generally required to be rolled up after sunrise and put down before sunset. The current thermal insulation blankets mainly rely on electric mechanical roller shutters or traction, which can easily cause the thermal insulation blankets to be torn and damaged, and at the same time cause the thermal insulation capacity of the thermal insulation blankets to decrease year by year. Therefore, traditional solar greenhouse thermal insulation blankets usually have a short service life of only 3-5 years and require annual maintenance. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The purpose of the present invention is to provide a light and easily retractable solar greenhouse insulation blanket, which is used to overcome the shortcomings of the insulation blankets in the prior art that are bulky and easy to be damaged, provide strong technical support for greenhouse insulation, and thus improve the production efficiency of facility agriculture.

[0006] (II) Technical solution

[0007] The technical solution of the present invention is as follows:

[0008] A design of an inflatable thermal insulation blanket for a solar greenhouse and a method for making the same, comprising a double-layer frame erected parallel to the greenhouse roof surface and a sealed flexible bag-like body arranged between the interlayers of the double-layer frame; one end of the bag-like body is fixed to the bottom of the double-layer frame; the bag-like body expands and fits between the interlayers of the double-layer frame after being inflated, and slides down to the bottom of the double-layer frame as a whole after being deflated.

[0009] Preferably, the double-layer frame includes the greenhouse's own frame and a new frame that is parallel to the shed surface and erected on the outside thereof.

[0010] Preferably, the interlayer thickness of the double-layer skeleton is 10 cm, and the thickest part of the bag-like body after being inflated is no more than 15 cm.

[0011] Preferably, the bag-shaped body is formed by heat-seaming two layers of fabric membrane material.

[0017] Preferably, a plurality of identical bag-shaped bodies connected in sequence are arranged side by side between the double-layer skeleton interlayers.

[0018] (III) Beneficial effects

[0019] The present invention utilizes the design of an inflatable thermal insulation quilt for a solar greenhouse and its manufacturing method to replace the traditional thermal insulation quilt for a solar greenhouse, which, on the one hand, makes the greenhouse insulation extremely light; on the other hand, because the inflatable thermal insulation quilt for a solar greenhouse can naturally slide to the bottom of the double-layer frame under the action of gravity after being deflated, the tearing damage to the thermal insulation quilt caused by the traction of an electric mechanical roller blind is avoided, thereby extending the service life of the thermal insulation quilt; at the same time, the inflatable thermal insulation quilt of the present invention is easy to operate and use, and has a good thermal insulation effect, so it is very suitable for promotion and application, and can provide strong technical support for greenhouse insulation, thereby improving the production efficiency of facility agriculture.

[0025] The following is a further description of the specific implementation of the invention in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 4 The inflatable heat-insulating quilt for solar greenhouse shown in the figure comprises a double-layer frame 2 erected in parallel along the greenhouse shed surface, a sealed flexible bag-like body 5 is arranged between the interlayers of the double-layer frame 2, the double-layer frame 2 is mainly used to provide space for the bag-like body 5 after inflation, and can ensure that the bag-like body 5 will not be blown away by strong wind; one end of the bag-like body 5 is fixed to the bottom of the double-layer frame 2, and the other end can be movably connected to the top of the double-layer frame 2 during and after inflation; the bag-like body 5 is provided with an inflation port, which can be connected to the inflation port through an inflation pump to fill the bag-like body The bag-shaped body 5 is inflated; after being inflated, it expands and can be stuck between the interlayers of the double-layer frame 2. After being deflated, the bag-shaped body 5 slides down to the bottom of the double-layer frame 2 as a whole; the inflatable bag-shaped body 5 is used to replace the traditional quilt filled with materials such as cattail, straw, recycled cotton or foamed plastic, so that the thermal insulation quilt is very light; and since it can be retracted without the use of an electric mechanical roller shutter, the service life of the thermal insulation quilt is greatly extended; at the same time, after being soaked by rain or snow, the weight will not increase significantly, and the thermal insulation performance will not decrease significantly.

[0027] Among them, the double-layer frame 2 includes the greenhouse's own frame and a new frame parallel to the roof and erected on the outside. This makes more full use of the greenhouse's own frame, saves materials for the solar greenhouse insulation blanket, and reduces costs. The thickness of the interlayer of the double-layer frame 2 is set according to actual needs. In this example, it is preferably 10 cm. The thickest part of the bag-like body 5 after inflation is no more than 15 cm, so that the bag-like body 5 can be firmly engaged in the interlayer of the double-layer frame 2 after inflation.

[0028] Among them, the bag-shaped body 5 is formed by heat-stitching two layers of fabric membrane materials; the fabric membrane material can be one or more of PVC (polyvinylchloride, polyvinyl chloride) membrane material, PTFE (Polytetrafluoroethene, polytetrafluoroethylene) membrane material and PVF (polyvinyl fluoride, polyvinyl fluoride) membrane material, and the thickness of a single layer of fabric membrane material is 1.6mm-3.2mm; the fabric membrane material has the advantages of being not easy to tear, no debonding layer, good sealing, and low density. It is very suitable to use fabric membrane material as the material of the flexible bag-shaped body.

[0029] The bag-like body arranged between the interlayers of the double-layer skeleton 2 may be a large bag-like body, or may be a plurality of small bag-like bodies arranged side by side and connected in sequence; each small bag-like body has the same specification, which is convenient for assembly.

[0030] Among them, a traction mechanism is arranged on the top of the double-layer frame 2, and the other end of the bag-like body 5 is connected to the traction mechanism; before the bag-like body 5 is inflated, the traction mechanism is used to pull the bag-like body 5 to the top of the double-layer frame 2, which saves manpower and improves production efficiency; wherein, the traction mechanism includes a traction machine 3, the traction main shaft 6 of the traction machine 3 is connected to the traction rope 7, and the traction rope 7 is connected to the bag-like body 5; slide rails 8 are arranged on the edges of both sides of the double-layer frame 2 to facilitate the movement of the bag-like body 5 and prevent the bag-like body from being scratched.

[0031] A storage groove 4 is provided at the bottom of the double-layer frame 2 ; after the bag-like body 5 is deflated, it slides into the storage groove 4 as a whole, so that the bag-like body 5 can be stored conveniently.

[0032] Among them, the side of the bag-shaped body 5 that is in contact with the greenhouse roof is coated with a reflective film to enhance the long-wave reflection ability, thereby reducing heat loss and improving thermal insulation ability.

[0033] The inflatable thermal insulation blanket for the solar greenhouse of the present invention is not only extremely light, but also avoids the tearing damage to the thermal insulation blanket caused by the traction of the electric mechanical roller blind, thereby extending the service life of the thermal insulation blanket; at the same time, the inflatable thermal insulation blanket of the present invention is easy to operate and use, and has a good thermal insulation effect, so it is very suitable for promotion and application, and can provide strong technical support for the thermal insulation of the solar greenhouse, thereby improving the production efficiency of facility agriculture; at the same time, the inflatable thermal insulation blanket for the solar greenhouse of the present invention can not only be used for the thermal insulation of the solar greenhouse, but also can be used for the thermal insulation of multi-span greenhouses and plastic arch sheds after matching improvement; combined with the matching device, it also has broad application prospects in animal husbandry or other aspects requiring thermal insulation.

[0034] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the protection scope of the present invention.
