Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouses, and particularly relates to an arch shed of a double-film single-body greenhouse. Background Art

[0002] A single-body greenhouse, also known as a single-body arch shed or a single-temperature greenhouse, is a common agricultural cultivation facility. Its structure is relatively simple, mainly composed of a single arc-shaped or semi-circular frame covered with plastic film or other light-transmitting materials. This design enables the single-body greenhouse to have good ventilation and lighting effects, and to provide a certain degree of heat preservation effect to some extent.

[0003] However, the single-body greenhouses in the prior art usually only have a single-layer covering, and have poor snow and wind resistance in the northern regions, and are easily collapsed by snow and wind. In traditional film greenhouses, bamboo and wood greenhouses have a relatively simple skeleton structure and columns inside the room, which affect the internal operation space. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide an arch shed of a double-film single-body greenhouse to solve the technical defects of the traditional film greenhouse in terms of heat preservation performance, snow and wind resistance, and internal space utilization as mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An arch shed of a double-film single-body greenhouse includes an outer shed arch rod and an inner shed arch rod. The outer shed arch rod sleeves the inner shed arch rod. A first outer shed longitudinal rod and a second outer shed longitudinal rod are respectively and fixedly installed inside the outer shed arch rod and the inner shed arch rod. A first layer of film and a second layer of film are respectively laid on the surfaces of the outer shed arch rod and the inner shed arch rod. A heat preservation quilt can be filled between the first layer of film and the second layer of film.

[0007] As a preferred scheme of the utility model, a shed head column is fixedly installed inside the shed head of the outer shed arch rod; the beam spacing inside the outer shed arch rod is 0.8m; the first outer shed longitudinal rod inside the outer shed arch rod is a certain number of channels.

[0008] As a preferred scheme of the utility model, a first clamping plate and a second clamping plate are respectively and fixedly installed on both sides of the outer surfaces of the outer shed arch rod and the inner shed arch rod. Both the first clamping plate and the second clamping plate are in a U shape; there are two second clamping plates on the surface of the inner shed arch rod; there are four first clamping plates on the surface of the outer shed arch rod; the beam spacing inside the outer shed arch rod is 2m.

[0009] As a further scheme of the utility model, a cross bar can be clamped inside the first clamping plate and the second clamping plate, and the first layer of film and the second layer of film can be buckled inside.

[0010] As a preferred solution of the utility model, manual film rollers are fixedly installed on the lower ends of both sides of the outer shed arch rod, and the film roller rods of the manual film rollers can roll up the first layer of film at the lower end of the first clamping plate.

[0011] As a preferred solution of the utility model, outer shed diagonal braces are fixedly installed on both sides of the outer surface of both ends of the outer shed arch rod.

[0012] Compared with the prior art, the double-film single-body greenhouse provided by the utility model has the following beneficial effects:

[0013] 1. The utility model adopts the design of the outer shed arch rod, the inner shed arch rod, the first roll film and the second film, so that the outer shed arch rod is sleeved on the outer surface of the second film of the inner shed arch rod through the first film, and there is a distance between the first film and the second film, and the distance between the first film and the second film can be filled with a thermal insulation blanket, thereby forming a three-film and one-quilt structure, so that the air layer between the inner and outer first and second films cannot flow, thereby greatly reducing heat loss and improving the thermal insulation performance in the greenhouse, so that agricultural production can be carried out in cold weather, and the normal growth of crops can be guaranteed even in the low temperature environment in winter.

[0014] And through the double arch and double membrane structure formed by the outer shed arch rod and the inner shed arch rod, a layer of arch is added on the top of the beam, and a distance is maintained between the arches to form two upper and lower insulation layers. This design enhances the overall stability of the greenhouse, so there is no need for internal support columns to maintain the stability of the structure, which in turn provides more space for crop growth. It also facilitates mechanized operations and improves work efficiency.

[0015] 2. The utility model adopts the design of a manual film roller and a film roller rod. During use, the staff can rotate the manual film roller to drive the film roller rod to roll up the first layer of film, thereby controlling the ventilation of the greenhouse, and adjusting the temperature difference between the inside and outside, avoiding damage to crops caused by excessively high or low temperatures, and promoting air circulation and reducing humidity in the greenhouse.
