Description

Multi-span greenhouse based on sealed air heat preservation principle Technical Field The utility model relates to the field of multi-span greenhouses, in particular to a multi-span greenhouse based on a sealed air heat preservation principle. Background The chinese patent with the publication number CN115152484a discloses a multi-span greenhouse structure and a method for installing the multi-span greenhouse structure, the multi-span greenhouse structure includes a plurality of rows of center posts and a plurality of arch truss modules, each row of posts supports two rows of arch truss modules which are oppositely arranged, each arch truss module includes a plurality of first spacing members and a plurality of arch units, the plurality of arch units are arranged at intervals along the extending direction of the first spacing members, wherein each arch unit includes web members and arch frames, the web members are connected to the bottom ends of the arch frames, and at least two first spacing members are arranged at intervals along the up-down direction and are respectively connected to the web members, so as to form truss parts of the arch truss modules, so as to replace truss structures originally arranged on the center post structure. This greenhouse structure cancels the truss structure that originally needs to set up alone, and the quick assembly of being convenient for still has following defect: (1) The top of the existing greenhouse is of a plastic film structure, the light transmittance performance of the existing greenhouse is poor, an effective sunlight irradiation effect cannot be provided for the interior of the greenhouse, and the existing greenhouse is of a single-layer plastic film heat preservation structure, so that the winter protection effect is poor; (2) The support component of the existing greenhouse is single, and can not be firmly and stably supported when encountering strong wind. Therefore, we make improvements to this, and put forward a multi-span greenhouse with the sealed air heat preservation principle. Disclosure of utility model Aiming at the problems and defects existing in the prior art, the utility model aims at a multi-span greenhouse based on a sealed air heat preservation principle, and the greenhouse has good light transmission performance, good heat preservation effect and firmness and stability when encountering strong wind. The multi-span greenhouse based on the sealed air heat preservation principle comprises main upright posts, wherein a building assembly is arranged between the main upright posts, heat preservation assemblies are arranged on the transverse outer sides of the building assembly, the building assembly comprises auxiliary upright posts arranged on the inner sides of the main upright posts, girts are alternately arranged on the outer sides of the lower sides of the auxiliary upright posts and the main upright posts, stay wires are arranged on the upper sides of the auxiliary upright posts and the upper sides of the main upright posts, the heat preservation assemblies comprise heat preservation curtains which are vertically built by the stay wires, sealing layers are cooperatively arranged in the heat preservation curtains, longitudinal chords are arranged on the two sides of the upper sides of the stay wires, truss auxiliary rods are alternately arranged between the longitudinal chords, outer sunshade upright posts are cooperatively arranged on the upper sides of the stay wires, outer sunshade stringers are cooperatively arranged on the outer sunshade upright posts, glass roofs are cooperatively arranged on the outer sides of the main upright posts, and a sealing air layer is cooperatively arranged on the outer sides of the sealing air layer.
