Description

Independent permanent inflation unit type greenhouse film

Technical Field

The utility model relates to a double-deck or multilayer big-arch shelter membrane structure.

Background

The plastic film greenhouse is widely applied to agriculture, has less building investment and higher economic benefit, can resist natural disasters, resist cold, preserve heat, resist drought and waterlogging, cultivate early and later, prolong the growth period of crops, and achieve the purposes of early maturity, late maturity, yield increase and stable yield.

The common greenhouse film is of a single-layer structure and has the defect of poor heat insulation performance.

Therefore, CN201018806Y provides an inflatable greenhouse film, which has a plurality of longitudinally extending longitudinal thermocompression bonding lines between upper and lower film layers to form a plurality of independent inflatable chambers, and when in use, the greenhouse film is cut along the transverse direction and then inflated from the opening generated at the cut position to form the inflatable greenhouse film. However, the inflatable greenhouse film is actually of a single-layer film structure at the position of the longitudinal hot-pressing bonding line, and has the defect of heat preservation performance.

CN102771342A provides a cold-resistant greenhouse of inflatable double-deck cavity, and the equipartition has a plurality of support gas columns in the middle of upper and lower two-layer plastic film, and this patent also needs the field inflation to use, also has the leakproofness not good, produces the gas leakage problem easily in the use, the later maintenance difficulty scheduling problem.

CN2598337Y provides a double-deck inflation heat preservation greenhouse membrane, is equipped with a plurality of hot pressing bonding lines along the horizontal between upper and lower two-layer film to form the banding air bag, is equipped with the air cock that fills the air on the air bag, uses in the field inflation. Obviously, the patent also has the problems of insufficient heat preservation performance at the position of the hot-pressing bonding line, poor sealing performance, easy air leakage, difficult later maintenance and the like.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned technical problem that exists among the prior art, the utility model provides an independent permanent inflation unit formula big-arch shelter membrane, the needs scene that its purpose was solved current double-deck big-arch shelter membrane existence is aerifyd, is not enough, the leakproofness is not good, produce gas leakage problem, later maintenance difficulty scheduling problem easily at the hot pressing bonding line position thermal insulation performance.

In order to achieve the above object, the utility model adopts the following technical scheme:

an independent permanent inflatable cellular greenhouse film comprising at least two layers of film arranged in a stack, characterized in that: the greenhouse film is characterized by further comprising a connecting film edge connected between two adjacent layers of films, the connecting film edge and the two adjacent layers of films jointly enclose to form a plurality of closed units, and the closed units are inflated to form independent permanent inflation units when the greenhouse films are manufactured.

The independent permanent inflation unit type greenhouse film comprises: each closed unit is polygonal on the plane of the greenhouse film.

The independent permanent inflation unit type greenhouse film comprises: the polygon is a triangle, a quadrangle, a pentagon, a hexagon or an octagon.

The independent permanent inflation unit type greenhouse film comprises: the side length of the polygon is 3-20cm.

The independent permanent inflation unit type greenhouse film comprises: the plurality of closed units are arranged in a matrix or staggered mode.

The independent permanent inflation unit type greenhouse film comprises: all the closed units are connected in sequence, and the total area of all the closed units is equivalent to that of the greenhouse film.

The independent permanent inflation unit type greenhouse film comprises: the plurality of closed cells are separated from each other, and the total area of all the closed cells is greater than 50%, 60%, 70% or 80% of the total area of the greenhouse film.

The independent permanent inflation unit type greenhouse film comprises: each closed unit is circular, oval or polygonal on the plane of the greenhouse film.

The independent permanent inflation unit type greenhouse film comprises: the plurality of closed units are arranged in a matrix form or staggered form.

The utility model provides an independent permanent inflation unit formula big-arch shelter membrane, compared with the prior art, do not connect through the hot pressing bonding line between upper film and the lower floor's film, do not have the heat preservation leak, directly cover this big-arch shelter membrane during the construction can on the big-arch shelter, high durability and convenient installation, more importantly, and each seals the unit and accomplish promptly when big-arch shelter membrane is made and aerify in order to form independent permanent inflation unit, therefore the leakproofness is good, be difficult to leak gas, even wherein the several seals the unit and is punctured gas leakage, can not influence other sealing element's sealing performance yet, heat preservation performance to whole big-arch shelter membrane does not basically have the influence, do not need later maintenance basically.
