Description

Technical Field

[0001] The embodiments of the present application relate to the field of agricultural technology, and in particular to a waterproof composite thermal insulation blanket for a greenhouse. Background Art

[0002] At present, the front roofs of domestic solar greenhouses are basically insulated with thermal insulation blankets, which are basically composed of waterproof cloth, tension felt, EPE cloth, needle-punched felt, aluminized film and other materials. Early greenhouse thermal insulation blankets only focused on the thermal insulation performance of the materials, but ignored the waterproof performance of the thermal insulation blankets. The greenhouse thermal insulation blankets are easily soaked by rain and snow, resulting in a decrease in thermal insulation performance. In order to improve the thermal insulation performance of the greenhouse thermal insulation blankets, waterproof materials are added to the upper and lower outer surfaces of the thermal insulation blankets to improve the waterproof and thermal insulation performance of the greenhouse thermal insulation blankets. During use, it was found that since this type of thermal insulation blanket directly uses waterproof material on the lower surface, after the thermal insulation blanket is covered, the moisture in the greenhouse seeps out through the vents, condenses into water between the greenhouse film and the thermal insulation blanket, and forms muddy water on the surface of the greenhouse film, which easily contaminates the greenhouse film and affects the lighting performance of the greenhouse. Secondly, the current greenhouse thermal insulation blankets are connected with single-sided Velcro. After water seeps into the Velcro, it is not easy to dry inside the thermal insulation blanket, which still affects the thermal insulation performance of the thermal insulation blanket. Moreover, the single-sided Velcro connection is easy to pull apart and cannot completely cover the greenhouse, resulting in reduced greenhouse insulation performance. Utility Model Content

[0026] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present application proposes a greenhouse waterproof composite thermal insulation quilt, comprising: a thermal insulation quilt main body 1, the thermal insulation quilt main body 1 comprises a waterproof layer 2, a thermal insulation core layer, a waterproof heat-insulating layer 5 and a bottom layer 6 arranged in sequence from top to bottom; a connecting part, the connecting part is arranged at both ends of the thermal insulation quilt main body 1, the connecting part comprises an upper Velcro 7 and a lower Velcro 8, the upper Velcro 7 is arranged on the waterproof layer 2, and the lower Velcro 8 is arranged on the bottom layer 6, and two adjacent greenhouse waterproof composite thermal insulation quilts are connected via the connecting part.

[0028] The greenhouse waterproof composite thermal insulation quilt provided in the embodiment of the present application includes a thermal insulation quilt main body 1 and a connecting part. The thermal insulation quilt main body 1 includes a waterproof layer 2, a thermal insulation core layer, a waterproof thermal insulation layer 5 and a bottom layer 6 arranged in sequence from top to bottom. The greenhouse waterproof composite thermal insulation quilt provided in the embodiment of the present application is aimed at the problems that the existing thermal insulation quilts have poor waterproof performance, the lower surface waterproof layer 2 is easy to contaminate the greenhouse film, and the thermal insulation quilts are tightly connected and easy to pull apart, and cannot completely cover the greenhouse, resulting in reduced thermal insulation performance of the greenhouse. The thermal insulation quilt main body 1 adopts a multi-layer composite structure of a waterproof layer 2, a thermal insulation core layer, a waterproof thermal insulation layer 5 and a bottom layer 6. The surface waterproof layer 2 and the thermal insulation waterproof layer 2 protect the thermal insulation core layer from being soaked by rain and snow to reduce the thermal insulation performance, and the bottom layer 6 can be made of cotton materials such as tension felt, which have a certain ability to absorb moisture and clean the greenhouse film to prevent water vapor condensation from contaminating the greenhouse film. In terms of the connection method of the thermal insulation quilt, two adjacent greenhouse waterproof composite thermal insulation quilts can be bonded together by the upper Velcro 7 and the lower Velcro 8, which can increase the connection strength of the thermal insulation quilt. The greenhouse waterproof composite thermal insulation quilt provided in the embodiment of the present application effectively solves the problems of the thermal insulation quilt's waterproofness, greenhouse film pollution and connection tightness, and enhances the use performance of the thermal insulation quilt.

[0029] When manufacturing the greenhouse waterproof composite thermal insulation quilt provided in the embodiment of the present application, in addition to the waterproof layer 2, the thermal insulation core layer, the waterproof thermal insulation layer 5 and the bottom layer 6 are first sewn together with a quilting machine, while enhancing the strength of the thermal insulation quilt body 1, ensuring that the layers do not fall off or tear, and then the waterproof layer 2, the thermal insulation core layer, the waterproof thermal insulation layer 5 and the bottom layer 6 are sewed around the edges with a sewing machine. This manufacturing method does not damage the waterproof performance of the surface layer. The thermal insulation quilt connection method is to sew the upper and lower Velcro tapes 7 and 8 on the upper and lower surfaces of both sides of the thermal insulation quilt body 1, respectively. Such a setting facilitates the production and processing of the greenhouse waterproof composite thermal insulation quilt.

[0030] In a feasible embodiment, the material used to prepare the bottom layer 6 includes tension felt or cotton felt.

[0031] In this technical solution, materials for preparing the bottom layer 6 are further provided. By selecting tension felt or cotton felt, the contact layer of the greenhouse waterproof composite insulation blanket has a certain ability to absorb moisture and clean the greenhouse film, preventing water vapor condensation from contaminating the greenhouse film.

[0032] In a feasible implementation, the upper hook and loop fastener 7 is sewn on the waterproof layer 2; and the lower hook and loop fastener 8 is sewn on the bottom layer 6. This arrangement makes the fixing method of the connection part more reliable.

[0033] In a feasible implementation manner, the heat-insulating core layer, the waterproof heat-insulating layer 5 and the bottom layer 6 are sewn together. Such an arrangement can reduce the probability of cracking of the heat-insulating blanket body 1.

[0034] In a feasible implementation, the greenhouse waterproof composite thermal insulation quilt further includes: a coating layer, which is sewn on the peripheral side of the thermal insulation quilt body 1. Such an arrangement can seal the peripheral side of the thermal insulation quilt body and further improve the waterproof effect.

[0035] In a feasible implementation, the material for preparing the waterproof layer 2 includes plastic film, spray-bonded cotton, woven membrane or Oxford waterproof cloth. Such a configuration ensures waterproof performance.

[0036] In a feasible implementation, the thermal insulation core layer includes: a first thermal insulation layer 3 and a second thermal insulation layer 4, and the materials used to prepare the first thermal insulation layer 3 and the second thermal insulation layer 4 are different. Such an arrangement can further improve the thermal insulation effect of the thermal insulation core layer.

[0037] In a feasible embodiment, the material for preparing the first core layer insulation layer 3 includes tension felt, needle felt or cotton felt, and the material for preparing the second core layer insulation layer 4 includes space cotton or cotton. Such a setting can further improve the insulation effect.

[0038] In a feasible embodiment, the material for preparing the waterproof and heat-insulating layer 5 includes EPE cloth, aerogel composite material or aluminum-plated film. Such a configuration can improve the waterproof effect of the bottom layer 6 of the thermal insulation quilt body 1.

[0039] In a feasible implementation manner, the material used to prepare the connection portion includes Oxford waterproof cloth or woven rainproof cloth. Such an arrangement makes the connection portion more reliably fixed. Example

[0040] like Figure 1 , Figure 2 As shown, the utility model is a greenhouse waterproof composite thermal insulation quilt, and its main thermal insulation quilt body 1 includes: a waterproof layer 2, a first core layer thermal insulation layer 3, a second core layer thermal insulation layer 4, a waterproof heat insulation layer 5, and an upper Velcro 7 and a lower Velcro 8 are sewn on the thermal insulation quilt body 1. The greenhouse waterproof composite thermal insulation quilt provided by the utility model adopts a reasonable combination of a multi-layer composite structure and a double-layer connection method, which solves the contradiction between the waterproof and thermal insulation of the greenhouse thermal insulation quilt and the pollution of the greenhouse film, and the thermal insulation quilt body 1 adopts a double-layer Velcro connection to enhance the tightness of the connection between the greenhouse thermal insulation quilt body 1. The greenhouse waterproof composite thermal insulation quilt body 1 protects the thermal insulation core layer from being soaked by rain and snow through the waterproof layer 2 and the waterproof heat insulation layer 5, and the bottom layer 6 adopts cotton materials such as tension felt to prevent water vapor condensation from polluting the greenhouse film.

[0041] When in use, the thermal insulation quilt body 1 is covered on the greenhouse roof in turn, and the lower Velcro 8 on both sides of the thermal insulation quilt body 1 is bonded to the upper Velcro 7 of another greenhouse waterproof composite thermal insulation quilt, so that the connection between the greenhouse waterproof composite thermal insulation quilts is tighter. The greenhouse waterproof composite thermal insulation quilt is opened during the day to allow the greenhouse to light and store heat, and the greenhouse waterproof composite thermal insulation quilt is covered at night to keep warm, reducing heat loss, which is very beneficial to improving the quality and yield of greenhouse crops.

[0042] When the main body 1 of the greenhouse waterproof composite thermal insulation quilt is produced and processed, in addition to the waterproof layer 2, the thermal insulation core layer, the waterproof thermal insulation layer 5 and the bottom layer 6 are first sewn together with an industrial quilting machine with a line spacing of 10-20cm, while enhancing the strength of the thermal insulation quilt, ensuring that the layers do not fall off or tear, and then the waterproof layer 2, the thermal insulation core layer, the waterproof thermal insulation layer 5 and the bottom layer 6 are sewed around the edges with a sewing machine. This production method does not damage the waterproof performance of the waterproof layer 2. An upper Velcro 7 is sewn on the upper surface of one side of the thermal insulation quilt main body 1 with an industrial sewing machine, and a lower Velcro 8 is sewn on the lower surface.

[0043] During use, the utility model can adopt the method of overall driving of the internal insulation system and pulling and releasing the insulation curtain in blocks to solve the insulation problem of the side wall of the multi-span greenhouse. By using the insulation curtains on the side walls of the multi-span greenhouse in conjunction with the top insulation system, the insulation curtains can be closed at night to effectively improve the insulation capacity of the multi-span greenhouse, reduce heat loss, and reduce the heating consumption of the multi-span greenhouse. Pulling open the insulation curtains for lighting during the day has little effect on the daytime lighting capacity of the greenhouse, thereby improving the environmental control capacity of the multi-span greenhouse, which is very beneficial to the production of greenhouse crops. It is a new type of insulation method for the side walls of multi-span greenhouses with broad prospects for promotion and application.

[0044] The utility model adopts a multi-layer composite structure to reasonably match the waterproof and heat-insulating properties of the greenhouse, and at the same time has a certain ability to absorb moisture and clean the greenhouse film, thereby preventing water vapor condensation from contaminating the greenhouse film.
