Abstract

The invention relates to a greenhouse with adjustable height and gradient, which comprises a plurality of rows of main uprights and longitudinal beams, wherein the main uprights are arranged on the ground; the longitudinal beams are supported by the corresponding rows of main uprights; both sides of the longitudinal beams are provided with greenhouse top surfaces; the base sides of the greenhouse top surfaces are connected to the corresponding longitudinal beams and can rotate around the corresponding longitudinal beams; greenhouse top surface fulcrum bars are arranged between the greenhouse top surfaces and the main uprights; the upper ends of the greenhouse top surface fulcrum bars are hinged on the greenhouse top surfaces; the bar parts of the greenhouse top surface fulcrum bars are inserted on the main uprights; the width W of each greenhouse top surface and the height h of each main upright have the following relation that W=0.7-1.2h; and the transverse distance H between each two adjacent rows of main uprights is less than the sum 2W of the widths of two greenhouse top surfaces, so that the adjacent greenhouse top surfaces can be overlapped. The greenhouse is used as a multi-span greenhouse or a single greenhouse and can give consideration to the requirements on ventilation, rain prevention, sun protection, heat preservation and the like; moreover, when the greenhouse is not required, the greenhouse top surfaces can be turned over downwards, so that the ground is in a semi-open state; and the greenhouse is convenient for mechanical operation and is very convenient to use.

Description

technical field

[0001] The invention belongs to the technical field of greenhouses, in particular to a greenhouse with adjustable height and slope. Background technique

[0002] At present, the more practical greenhouses generally include single-span greenhouses, multi-span greenhouses, sunlight greenhouses, simple plastic arch sheds, etc. Among them, the advantages of single-span greenhouses are that it is convenient to drain rain, and the snow load can automatically slide off when the shed surface angle is above 15 degrees. Good ventilation and heat dissipation, the disadvantages are large heat dissipation in winter, high cost, and not easy to scale up; the advantages of multi-span greenhouses are high land utilization rate, good thermal insulation performance, large span, large space, easy for mechanized and centralized management, and the disadvantages are natural ventilation ability Poor, no snow-covered load sliding function, high requirements for structural strength,...
