Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouse heat preservation and heat insulation materials, and relates to a greenhouse heat preservation and light transmission interlayer. Background Technique

[0002] The advantage of greenhouse planting is to overcome the influence of the external natural environment and let plants grow in a comfortable greenhouse all day long. In order to overcome the influence of severe cold weather on plant growth, increase the temperature inside the greenhouse at night, and reduce the heat radiation at night, multiple layers of thin films are used to cover the greenhouse frame. In addition to the above-mentioned method of laying coverings to preserve the heat inside the greenhouse, coal fire heating is also required. Traditional coverings include straw curtains, rush mats, cotton quilts, etc., but they are inconvenient to use, time-consuming and laborious. Especially after being wet by rain and snow, not only does the weight increase, but the heat preservation performance also decreases accordingly. Traditional coverings are thick and have poor light transmittance. Although using plastic film solves the problem of light transmission, the heat insulation performance is correspondingly lost. For this reason, various inflatable heat preservation devices have been developed. For example, the invention patent application with the application number CN201210213347.5 disclosed in China. The patent application materials of this application disclose that a protective layer is provided on the outer surface of the outer layer of the device, an airbag is built in the inner layer, and an airbag inner layer protective layer is provided on the inner layer of the airbag; a communication pipe is provided between adjacent airbags, an airbag inflation pipe is provided on the upper part of the outer layer, fixing rings are provided on the upper side and the left and right sides of the outer layer, and a bottom edge is provided on the lower part of the outer layer. The heat preservation device with the above structure connects the airbags through the communication pipe and inflates all the airbags at one time. However, as long as one airbag leaks, the entire heat preservation device will fail, which is difficult to maintain and has a high cost. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems existing in the prior art, and propose a greenhouse heat preservation and light transmission interlayer with low manufacturing cost, simple structure and convenient maintenance.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A greenhouse heat preservation and light transmission interlayer includes an outer plastic film, an inflatable bottle, and an inner plastic film. It is characterized in that ropes are arranged between the outer plastic film and the inner plastic film and are connected in a criss-cross pattern to form a grid. A sealed bottle cap is welded at the inflation port of the inflatable bottle, and a connection hole for the rope to pass through is opened at the end of the sealed bottle cap. Each inflatable bottle is filled with air at a pressure of 0.15 - 0.2 Mpa, and the inflatable bottles are placed horizontally and their upper and lower end faces are respectively abutted against the outer plastic film and the inner plastic film.

[0005] Further, the material of the inflatable bottle is PET. The PET material has good heat resistance and can maintain its excellent physical and mechanical properties within a relatively wide temperature range.

[0006] Further, the bottle body of the inflatable bottle is oval.

[0007] Further, the outer end of the sealed bottle cap has a raised trapezoidal connecting portion, and the connecting hole is formed on the connecting portion.

[0008] Further, the distance between laterally adjacent inflatable bottles is 40 - 50 cm.

[0009] Further, the distance between longitudinally adjacent inflatable bottles is 30 - 45 cm.

[0010] Further, the thickness of both the outer plastic film and the inner plastic film is 0.1 - 0.15 mm.

[0011] Compared with the prior art, the greenhouse heat - preservation and light - transmission interlayer of the present invention has the following advantages:

[0012] 1. Due to the air filled with a certain air pressure, the inflatable bottles will not shrink and deform under high - temperature exposure to the sun, and can maintain the heat - insulation effect for a long time.

[0013] 2. Low cost, the manufacturing cost of a single inflatable bottle is low, and it can be blow - molded. Each inflatable bottle is independently inflated without interference, and the installation and maintenance are simple. Only the damaged inflatable bottle needs to be replaced.

[0014] 3. The inflatable bottles and the inner and outer plastic films are all made of transparent materials, with good light transmission, enabling the plants in the greenhouse to receive better sunlight during the day.

[0015] 4. Good heat - preservation effect. The inner and outer plastic films are propped open by inflatable bottles to form an air layer for heat insulation. At night, it can slow down the heat dissipation in the greenhouse for a long time, reduce the amount of charcoal burned to maintain a constant temperature, and is more low - carbon, environmentally friendly and energy - saving.

[0016] 5. The greenhouse heat - preservation and light - transmission interlayer of the present invention is not only widely used in the planting industry, but can be extended to the aquaculture field in the future. BRIEF DESCRIPTION OF THE DRAWINGS
