Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of greenhouse equipment, in particular to a new type of energy-saving sunlight greenhouse special thermal insulation quilt unit and thermal insulation quilt. BACKGROUND

[0002] At present, energy-saving sunlight greenhouses are widely used in agricultural production, and their functions cover crop seedling, cultivation, edible fungus planting and breeding in multiple fields.

[0003] In the design of energy-saving sunlight greenhouses, the southward (sunward) usually uses thermal insulation cotton quilts for temperature regulation: rolled up during the day to fully receive sunlight, and laid down at night to achieve thermal insulation coverage. The thermal insulation cotton quilt is connected to the winding rod of the winding curtain machine through the bottom edge, and the winding operation is completed by rotating. The existing thermal insulation cotton quilt is mainly made of single or multiple layers of vacuum cotton, black cotton, felt, rainproof cloth and other materials.

[0004] However, the traditional cotton quilt has significant defects in actual use. First, the material is soft and has horizontal and vertical stretchability, which is easy to deform in use, causing the winding rod to run on a horizontal track. This curvature deformation makes it difficult to accurately control the travel distance of each winding and storage, which seriously affects the accuracy of the automatic operation of the greenhouse. Second, the sewing needle holes have water seepage risks, and external rainwater and greenhouse internal water vapor can easily seep into the inside of the cotton quilt through the needle holes. After the cotton quilt gets wet, its thermal insulation performance will be greatly reduced, and its weight will be significantly increased, which not only increases the load of the winding curtain machine, but also is more likely to cause mechanical damage. In addition, the traditional cotton quilt has weak weather resistance and aging resistance, and usually breaks after 3-5 years of use.

[0005] In order to break through these technical bottlenecks, it is urgent to research a new type of composite thermal insulation quilt based on new chemical materials, which aims to completely replace the traditional cotton quilt. SUMMARY

[0006] Therefore, in order to solve the technical problems of easy deformation and water seepage of the traditional cotton quilt, the present application provides a new type of energy-saving sunlight greenhouse special thermal insulation quilt unit and thermal insulation quilt, which uses rubber-plastic thermal insulation cotton as the main material and coats the front and back surfaces with weather-resistant glue layer and dense glass fiber fireproof cloth to form a thermal insulation quilt unit. After multiple thermal insulation quilt units are spliced, a thermal insulation quilt special for sunlight greenhouses is formed, which has good thermal insulation effect, aging resistance, high and low temperature resistance, horizontal and vertical deformation resistance, vertical softness and winding application, good water resistance, fireproofness, lightness and other characteristics, and can replace the traditional cotton quilt.

[0007] To achieve the above purpose, the present application provides the following technical scheme:

[0008] In a first aspect, a new type of energy-saving sunlight greenhouse special thermal insulation quilt unit comprises:

[0009] The rubber-plastic thermal insulation cotton is used as the main body of the thermal insulation quilt;

[0010] The weather-resistant glue layer is coated on the front and back surfaces of the main body of the thermal insulation quilt respectively;

[0011] The encrypted glass fiber fireproof cloth is covered on the weather-resistant glue layer on the front and back surfaces of the main body of the thermal insulation quilt respectively.

[0012] Preferably, the thickness of the main body of the thermal insulation quilt is 2-4 cm.

[0013] Preferably, the weather-resistant glue layer is formed by coating neutral silicone sealant.

[0014] Preferably, the thickness of the encrypted glass fiber fireproof cloth is 0.2 cm.

[0015] Preferably, the area of the encrypted glass fiber fireproof cloth is larger than that of the main body of the thermal insulation quilt, and the two side edges in the width direction and the length direction of the encrypted glass fiber fireproof cloth have reserved edges.

[0016] Preferably, the two side edges in the width direction each have a reserved edge of 3-5 cm for overall edge processing, and the two side edges in the length direction each have a reserved edge of 10 cm for being buckled to the eyelet connected to the roller lever of the roller shutter machine.

[0017] Preferably, the rubber-plastic thermal insulation cotton is EVA foam sponge without glue.

[0018] In the second aspect, the application provides a new type of energy-saving sunlight greenhouse special thermal insulation quilt formed by splicing the thermal insulation quilt units.

[0019] Preferably, the two adjacent thermal insulation quilt units are spliced in the form of a nylon snap fastener belt.

[0020] Preferably, the nylon snap fastener belt is formed by combining the nap surface and the hook surface.

[0021] Compared with the prior art, the application has the following beneficial effects:

[0022] (1) Main material: the rubber-plastic thermal insulation cotton is used as the core thermal insulation layer and has the characteristic of low thermal conductivity, and the thickness of 2-4 cm can be customized according to the temperature difference between the inside and outside of the greenhouse to achieve efficient thermal insulation; the width is preferably 2-4 m, and the length is preferably 10-15 m, which can cover the sunny surface of different specifications of greenhouses to ensure full coverage of the thermal insulation requirement.

[0023] (2) Surface coating: the weather-resistant glue layer is uniformly coated on the main body of the thermal insulation quilt by using weather-resistant glue (neutral silicone sealant), and is bonded with the encrypted glass fiber fireproof cloth to form a protective layer, which improves the aging resistance, high-temperature resistance and low-temperature resistance of the material, and prevents rainwater and water vapor from penetrating, thereby avoiding the technical problem of water penetration through the pinholes of traditional cotton quilts.

[0024] (3) Reinforced layer: glass fiber fireproof cloth, 100g / m2, 0.2cm thick, and the encryption encryption glass fiber fireproof cloth is integrated with rubber and plastic cotton, which limits the horizontal and vertical stretching to avoid the deformation of the arc during winding and unwinding, and improves the structural stability; the width direction of the two side edges is reserved for 3-5cm for edge covering, the internal material is protected, and the length direction of the two side edges is reserved for 10cm for binding the roller shutter machine connecting eyelet, which ensures the precision of winding and unwinding, and takes into account the fireproof and light features.

[0025] (4) Splicing component: the multiple cotton quilts are tightly bonded by the nylon snap fastener belt to prevent heat leakage through the gap; without needle and thread sewing, the needle hole water seepage is avoided, and the heat preservation sealing performance is improved.

[0026] In summary, the comprehensive performance of the present application is optimized as follows:

[0027] Heat preservation effect: the rubber and plastic heat preservation cotton and the composite structure design significantly improve the heat preservation performance;

[0028] Weather resistance and durability: the composite structure of weather-resistant adhesive and encrypted glass fiber fireproof cloth has excellent anti-aging, high temperature and low temperature performance, which solves the technical problem of 3-5 years of damage of traditional cotton quilt;

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] As shown in Figures 1-2 The present application provides a new type of energy-saving sunlight greenhouse special thermal blanket unit, comprising:

[0038] The rubber-plastic thermal insulation cotton is used as the thermal blanket body 1. The thickness of the material is determined according to the temperature difference to be reached inside and outside the greenhouse, and the thickness of 2-4 cm is preferred. The width of the single web is generally 2-4 meters, which is appropriate. The length of the web is determined according to the length of the arc surface from the sunny side of the greenhouse, i.e. the upper end to the lower edge, and is generally selected to be 10-15 meters, which is appropriate to achieve full coverage.

[0039] The rubber-plastic thermal insulation cotton is a flexible thermal insulation material made of rubber and plastic as the main raw material. It has excellent heat insulation, thermal insulation and moisture-proof performance. Its closed-cell structure can effectively prevent heat transfer, and at the same time has certain shock absorption and sound insulation effect. The preferred rubber-plastic thermal insulation cotton is EVA foam sponge without glue, which is an environmentally friendly foam made of EVA material, and is used as the preferred material for rubber-plastic thermal insulation cotton.

[0040] The rubber-plastic thermal insulation cotton is used as the core thermal insulation layer, which utilizes the low thermal conductivity of the rubber-plastic cotton to block the heat exchange between the inside and outside of the greenhouse, and maintain the temperature difference of the greenhouse. At the same time, it serves as a structural support and as a whole skeleton, bearing the surface coating (weather-resistant adhesive layer 2) and the reinforcing layer (dense glass fiber fireproof cloth 3).

[0041] The weather-resistant adhesive layer 2 is coated on the front and back of the thermal blanket body 1, respectively. The weather-resistant adhesive layer 2 serves to bond and fix the dense glass fiber fireproof cloth 3 and the rubber-plastic thermal insulation cotton, forming a composite structure, and improving the aging resistance, high temperature and low temperature resistance of the material, and adapting to outdoor environment.

[0042] The weather-resistant adhesive layer 2 refers to coating the surface of the thermal insulation quilt body 1 with a layer of weather-resistant adhesive, preferably a commercially available neutral silicone sealant. The weather-resistant adhesive is selected to be white or gray to maintain the clean and beautiful appearance of the surface after adhesion. The weather-resistant adhesive is diluted with a diluent (preferably a commercially available lipophilic neutral diluent) to a liquid state, and the ratio of the weather-resistant adhesive to the diluent is preferably 1:1.5. The liquid water is uniformly mixed to form a liquid water, which is uniformly applied to the surface of the rubber and plastic thermal insulation cotton by a roller brush. The amount of weather-resistant adhesive layer 2 is preferably 300 milliliters per square meter, which forms a weather-resistant adhesive layer 2. Then, a layer of reinforced glass fiber fireproof cloth 3 is covered on the surface of the weather-resistant adhesive layer 2. The specification of the reinforced glass fiber fireproof cloth 3 is preferably 200-320 grams per square meter, 0.2 centimeters thick, and laid flat. The rubber and plastic thermal insulation cotton and the reinforced glass fiber fireproof cloth 3 are pressed tightly and flat by a roller, and then dried.

[0043] The structure and processing method of the front and back of the rubber and plastic thermal insulation cotton are the same.

[0044] The reinforced glass fiber fireproof cloth 3 is covered on the weather-resistant adhesive layer 2 on the front and back of the thermal insulation quilt body 1, respectively. The reinforced glass fiber fireproof cloth 3 has the following advantages:

[0045] Anti-deformation: integrated with the rubber and plastic thermal insulation cotton, limiting horizontal and vertical stretching, avoiding deformation during winding and unwinding;

[0046] Fire and water resistance: the reinforced glass fiber fireproof cloth 3 is flame-retardant and dense, preventing rainwater and water vapor penetration;

[0047] Structural reinforcement: the reserved edge part is used for edge wrapping and connecting the roller shutter machine, improving the overall stability.

[0048] As shown in Figure 3 Since the east-west length of the greenhouse is not fixed, multiple thermal insulation quilt units are needed to be spliced. Therefore, the application provides a new type of energy-saving sunlight greenhouse special thermal insulation quilt, which is spliced by the above thermal insulation quilt units. The adjacent two thermal insulation quilt units (the first thermal insulation quilt unit 4 and the second thermal insulation quilt unit 5) are spliced in the form of a nylon snap fastener belt 6. The nylon snap fastener belt 6 is formed by combining a nylon fastener surface 7 with a nylon fastener hook surface 8. The nylon fastener surface 7 is 10 centimeters wide, and the nylon fastener hook surface 8 is divided into two 5 centimeter wide strips, which are fixed on the edges of the two thermal insulation quilt units. After the two thermal insulation quilt units are closely attached, the 10 centimeter wide nylon fastener surface 7 strip is pressed tightly and bonded. The front and back of the thermal insulation quilt unit are fixed in this way to prevent gaps and reduce performance.

[0049] In summary, the nylon snap fastener belt 6 can achieve:

[0050] Seamless splicing: multiple thermal insulation quilt units are tightly bonded by buckling to prevent heat leakage through gaps;

[0051] Convenient installation: no need for needle stitching, avoiding the problem of needle hole water leakage, and improving thermal insulation tightness.
