Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1 to 4, a film greenhouse comprises a plurality of upright posts 1, a plurality of arc-shaped ejector rods 2, a film 3, two layers of nets 4, a plurality of embedded parts 5, four steel pipes 6, two film rolling machines 7 and two film rolling shafts 8; the upright post 1 is fixed on the ground, the arc-shaped ejector rod 2 is arranged above the upright post 1, and the arc-shaped ejector rod 2 and the upright post 1 form a shed frame; the embedded parts 5 are uniformly arranged on two sides of the greenhouse and fixed on the ground.

The installation steps of the film 3 and the net 4 of the film greenhouse are as follows: firstly, covering a layer of net 4 on the outer side of the canopy frame, respectively penetrating two steel pipes 6 through meshes 41 at the bottom ends of two sides of the net 4 and respectively fixing the two steel pipes 6 on embedded parts 5 on the ground so as to fix the layer of net 4; then the film 3 is covered and fixed; and finally, covering a layer of net 4, respectively penetrating two steel pipes 6 through meshes 41 at the bottom ends of the two sides of the net 4, and respectively fixing the two steel pipes 6 on embedded parts 5 on the ground so as to fix the layer of net 4. The double-layer net 4 can effectively solve the problem that the film greenhouse is damaged by coastal strong wind; meanwhile, the fixing mode of the two ends of the net 4 can enable the edge of the net 4 to be stressed averagely, and the net 4 can be fixed better.

In order to facilitate the detachment of the steel pipes 6 on the net 4, detachable screws are arranged on the embedded parts 5.

Referring to fig. 1 again, in order to prevent air leakage caused by the local uneven formation of voids when the film 3 is lowered, fixing films 14 having a height of 20-30cm from the ground are respectively disposed on both sides of the greenhouse, and the fixing films 14 are overlapped with the lower edges of the film 3 lowered to the ground.

Referring to fig. 1 again, in order to make the greenhouse stronger and better in wind resistance, a beam 9 is transversely installed at the joint of the arc-shaped top rod 2 and the upright posts 1, a support rod 10 is arranged between the top of the arc-shaped top rod 2 and the middle point of the beam 9, and a plurality of steel bars 11 are fixedly connected between the upright posts 1 at the two sides of the greenhouse.

Meanwhile, in order to facilitate the entering and exiting of workers, the front end surface and the rear end surface of the greenhouse are respectively provided with a greenhouse door 12.

Referring to fig. 1 again, two sides of the front end of the greenhouse are respectively fixedly provided with a support 13, two film rolling machines 7 are respectively installed on the supports 13 in a manner of sliding up and down, two film rolling shafts 8 are respectively movably arranged on two sides of the greenhouse and are arranged in a linkage manner with the film rolling machines 7, and two ends of the film 3 are respectively wound and fixed on the film rolling shafts 8.

When the film 3 of big-arch shelter both sides is opened to needs, rotatory rolling film machine 7 drives rolling film axle 8 and upwards rotates, and then makes the film 3 of both sides upwards remove, and the film 3 book of both sides is on rolling film axle 8, realizes that the big-arch shelter both sides ventilates and form the air convection to can reach better aeration cooling's effect when high temperature weather. When the films 3 on the two sides of the greenhouse need to be put down, the film rolling machine 7 rotates reversely to drive the film rolling shaft 8 to rotate downwards, so that the films 3 on the two sides move downwards, and certain heat preservation and wind prevention effects can be achieved for crop cultivation in low-temperature weather.
