Abstract

A charging-and-exhaustion foldable booth greenhouse cold-proof insulating pad relates to a booth greenhouse cold-proof insulating pad, which is composed of a coating plastic bubble, a charging-exhaustion device, and a fixer, wherein the bubble is composed of sealed two layers of plastic films, while two outer surfaces of the upper and lower films are both coated with one layer of silver reflective film, the charging-exhaustion device is composed of charging and exhaustion tubes, and a charging-exhaustion pump. The utility model can fully utilize the thermal-chocked property of air and thermal radiation reflective property of the reflective film, to meet the cold-proof and insulation demands of booth greenhouse in winter, and fully utilize mechanical charging-exhaustion device, and reasonable width assembly, to realize convenient application.

Description

Fill exhaust and can roll up plastic greenhouse cold-proof heat insulation pad

Technical field

The utility model relates to a kind of plastic greenhouse cold-proof heat insulation in winter device.

Background technology

The material that is used for energy-saving solar green house production cold-proof heat insulation at night in winter at present mainly is that straw screen or mat and cotton are covered two kinds with mat.Straw screen or mat service life short (2～3 years), and easily scratch the canopy film; Solved the problems referred to above though cotton is covered with mat, cost an arm and a leg.These two kinds of materials also have two common drawback in addition, and the one, volume expands, and is difficult for mechanically actuated; The 2nd, after snowing, straw screen or mat, cotton are covered with mat and can be soaked, and not only the weight change is heavy unusually, and is difficult in many days dry, and influences cold-proof heat insulation.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned heat insulating material formed shortcoming and deficiency, and it is relatively low to design a kind of price, easily mechanically actuated, and be not subjected to sleet to influence the effective cold-proof heat insulation pad of heat-insulating and cold.

The utility model by the plated film plastic gas bag, fill exhaust apparatus, fixture is formed.The plated film plastic gas bag is formed by the two layers of plastic thin films sealing, up and down the silvery white reflective membrane of the equal plating one deck of two outer surfaces of film.Fill exhaust apparatus by charge and exhaust pipe with fill exhaust pump and form.Charge and exhaust pipe is fixed on the inner nexine of the plastic gas bag surface, and the charge and exhaust pipe structure is that two tracheaes vertically are connected with the tracheae that other parallel equidistant is arranged, and also links to each other with bottom charge and exhaust pipe mouth simultaneously.The charge and exhaust pipe mouth is used for connecting between the heat keeper air bag, or with fill exhaust pump and be connected.Even distribution spilehole on the charge and exhaust pipe.This pad is divided into 5 meters of width, 2 meters, 1 meter 3 kinds.

The utility model is compared at aspects such as heat insulation effect, clean hygienes with other material preferably simultaneously, and the mechanically actuated performance is good.This pad forms thick mattress by the inflation back, makes full use of the undesirable heat conductivity insulation dottle pin of air, and simultaneously, silvery white reflective membrane can reduce photothermal scattering and disappearing to greatest extent.Particularly very cold or lack sunlight daytime, when the canopy temperature was low, can reach the insulation gain of heat effect night by filling hot-air in air bag.Owing to be plastic material, can not be subjected to troubling of sleet fully.Not only can carry out manual operation easily during operation, and mechanically actuated is also very convenient.Well solved in the present greenhouse by solar heat production practices straw screen or mat, cotton and all inconvenience of insulation material and shortcoming such as covered with mat, inexpensive, convenient, good practical effect, and, at need with in the canopy during light filling, but daytime, reverse opening replenished illumination.

Embodiment

The utility model will be further described below in conjunction with drawings and Examples:

As shown in Figure 1, this pad partial width is divided into 5 meters, 2 meters, 1 meter three kinds, and air bag 1 length is generally 9 meters or definite with the width of greenhouse plane of illumination.Mainly fixedly film 3 and charge and exhaust pipe system 2 constitute this pad by plastic gas bag 1 and two ends.Plastic gas bag 1 is by being sealed to form around the two layers of plastic thin films up and down, and inflation back thickness reaches 5～20cm, and the silvery white reflective membrane of the equal plating one deck of two outer surfaces of air bag 1 is in order to reflected radiation warm.Fixedly film 3 is stayed at the two ends of air bag 1, fixedly remains for wearing the fixing hole 4 of dead lever on the film 3.Charge and exhaust pipe system 2 sticks on the air bag 1 nexine surface as shown in Figure 2, and two vertical plastic tubes are arranged tracheaes with many parallel equidistant and communicated, and with the bottom fill exhaust outlet communicate (as Fig. 3).Charge and exhaust pipe mouth 5 stays plastic gas bag 1 outside all 5cm long, and charge and exhaust pipe is the flexible plastic tube of diameter 2cm left and right sides thickness, evenly is equipped with ventilation hole on it.

During installation, according to concrete greenhouse canopy face length degree, determine the number of combinations of 5 meters, 2 meters, 1 meter three kinds of pads, penetrate up and down in the two ends fixing hole 4 with two dead levers, all pads are coupled together, with flexible pipe charge and exhaust pipe 5 is connected mutually successively again, should last mouth of pipe sealing of pad after the connection, first mouth of pipe with fill exhaust pump and be connected.During use, will go up or next dead lever fixing on green house, another dead lever is used for volume and puts this pad, launch this pad and be inflated to certain thickness night in the time of need being incubated, airtight insulation.Daytime is the time spent not, the emptying air, and the scrolling dead lever should fill up volume and put a side.Need to replenish according to the time, fixing lower end dead lever, to the outside, greenhouse at a certain angle reverse opening should fill up, the sun is reflexed in the canopy.

Claims

1. fill exhaust and can roll up plastic greenhouse cold-proof heat insulation pad, it is characterized in that: the plastic gas bag that is sealed to form around the two layers of plastic film is arranged, and the outside upper and lower surface of air bag all covers the silvery white reflective insulation film of one deck, and the adhesion of nexine one side is equipped with the charge and exhaust pipe road in the middle of the air bag.

2. want 1 describedly to fill exhaust and can roll up plastic greenhouse cold-proof heat insulation pad according to right, it is characterized in that: even distribution spilehole on the charge and exhaust pipe, structure is that two tracheaes vertically communicate with the tracheae of other parallel equidistant arranged distribution, link with bottom charge and exhaust pipe mouth simultaneously, charge and exhaust pipe is diameter 1～2cm flexible plastic tube.

3. want 1 describedly to fill exhaust and can roll up plastic greenhouse cold-proof heat insulation pad according to right, it is characterized in that: filling the width that exhaust can roll up plastic greenhouse cold-proof heat insulation pad is 5 meters, 2 meters, 1 meter three kinds.
