Abstract
The utility model discloses a water catchment thin film special for vegetable green house, comprising a first thin film layer fixed on a vegetable green house bracket, a second thin film layer arranged below the first thin film, a gas permeation hole on the second thin film layer, an evaporated water catchment device arranged on the first thin film layer. The vapor generated by vegetable respiration action enters into the space between the first thin film and the second thin film layer through the gas permeation hole on the second thin film layer. After the temperature drops, the vapor accumulates to form water beads on the inner wall of the first thin film layer. Because the vegetable green house has a certain slope, the first thin film layer and the second thin film layer are at the fixed state with one high side and one low side and the water beads flow into a vapor catchment device along the first thin film layer, so as to facilitate the uniform discharge process or secondary utilization and complete utilization of the water resource.
Description
Technical field
The utility model relates to a kind of film, relates in particular to a kind of green house of vegetables that is applicable to and collects the film of evaporation water.
Background technology
Mostly the plastic film that uses in the green house of vegetables is single layer structure at present, because solar radiation, photosynthesis of vegetables and respiration, can produce a lot of steam in the green house of vegetables, because the green house of vegetables sealing is relatively good, steam can't distribute in time, mostly be to accumulate on the plastic film at green house of vegetables top, after temperature reduces, steam is met the cold water that becomes and is assembled at the plastic film top, become the globule and will drip when gathering certain volume, existing green house of vegetables generally is not specifically designed to the facility of collecting this evaporation water, and the globule is constantly dripped arbitrarily, is not easy to collect and uses; Drip sometimes to spatter on staff's clothes clothes is drenched, be unfavorable for that the staff's is healthy.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, prevent that the globule from dripping the special-purpose catchment thin film of the green house of vegetables that spatters.
For solving the problems of the technologies described above, the technical solution of the utility model is: the special-purpose catchment thin film of green house of vegetables, comprise the first film layer that is fixed on the green house of vegetables support, described the first film layer below is provided with second thin layer, described second thin layer is provided with air-vent, also is provided with the evaporation water gathering unit on the described the first film layer.
As optimized technical scheme, described evaporation water gathering unit comprises the water leg that is fixed on the described green house of vegetables support, and the edge of described the first film layer is fixed on the inwall of described water leg.
As to improvement of the technical scheme, described the first film layer and described second thin layer are integral structure.
As to improvement of the technical scheme, described the first film layer and described second thin layer are split-type structural independently.
Owing to adopted technique scheme, the special-purpose catchment thin film of green house of vegetables comprises the first film layer that is fixed on the green house of vegetables support, and described the first film layer below is provided with second thin layer, described second thin layer is provided with air-vent, also is provided with the evaporation water gathering unit on the described the first film layer; The beneficial effects of the utility model are: the steam that the vegetables respiration produces enters in the space between the first film layer and second thin layer by the air-vent on second thin layer, temperature reduces the back and be accumulated into the globule on the inwall of the first film layer, because green house of vegetables has certain gradient, the first film layer and second thin layer also are a side height, stationary state that a side is low, the globule is gone into the evaporation water gathering unit along the first film laminar flow, be convenient to unified emission treatment or second use, help making full use of of water resource.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1-green house of vegetables support; 2-the first film layer; 3-second thin layer; The 4-air-vent; The 5-water leg.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in drawings, the special-purpose catchment thin film of green house of vegetables, comprise the first film layer 2 that is fixed on the green house of vegetables support 1, described the first film layer 2 below are provided with second thin layer 3, be formed with certain space between two thin layers, described second thin layer 3 is provided with air-vent 4, vegetables since the steam that photosynthesis or respiration produce can enter in the space between the first film layer 2 and second thin layer 3 by air-vent 4, after temperature is reduced to a certain degree, will become on the inwall that evaporation water accumulates in the first film layer 2, will be after gathering for a long time on the inwall that globule state is suspended on the first film layer 2.
Also be provided with the evaporation water gathering unit on the described the first film layer 2 of present embodiment, described evaporation water gathering unit comprises the water leg 5 that is fixed on the described green house of vegetables support 1, the edge of described the first film layer 2 is fixed on the inwall of described water leg 5, because green house of vegetables has certain gradient, the first film layer 2 and second thin layer 3 also are a side height, the stationary state that one side is low, be convenient to make the globule to flow in the water leg 5 along the first film layer 2 wall, can unify to handle or the secondary use to the evaporation water in the water leg 5 after collecting for a long time, help saving water resource.
Present embodiment as shown in drawings, described the first film layer 2 is an integral structure with described second thin layer 3, being described the first film layer 2 is fixed on the green house of vegetables support 1 away from one side of described water leg 5, then its folding below that covers the first film layer 2 is formed described second thin layer 3, and the end is fixed on the green house of vegetables support 1 of opposite side.Certain described the first film layer 2 also can be set to independently split-type structural with described second thin layer 3, promptly directly with two independently the film end be separately fixed at green house of vegetables support 1, make them be levels superimposition lid and distribute at green house of vegetables support 1.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
