Detailed Description

The utility model is described in further detail below with reference to the drawings and examples.

Referring to fig. 1 to 3, the present embodiment provides an aluminum gutter multi-span film greenhouse including a main structure 10 and a film covering material 20. The main structure 10 comprises uprights 11, aluminium furrows 12 and arches 13. The top end of the upright post 11 is connected with an aluminum gutter 12; the aluminum gutter 12 is made of a closed cavity aluminum profile with a hollow cavity in the middle, a drainage groove 14 is formed in the top of the aluminum gutter 12, dew collecting grooves 15 are formed in the top of the aluminum gutter 12 and located on two sides of the drainage groove 14 respectively, an arch 13 is installed in the dew collecting grooves 15, a drainage gap 16 is reserved in the dew collecting grooves 15, and the end portion of a film coating material 20 is fixed to the drainage groove 14.

Specifically, the greenhouse film material 20 is a high-strength woven film. The main structure 10 may include load beams, wall beams, overhead windows, trusses, etc., which are common structures for the main structure 10 and will not be described in any greater detail herein. The upright post 11 is used as a supporting structure of a greenhouse, a 100 multiplied by 50 multiplied by 3 hot galvanizing rectangular pipe is adopted, and the upper part of the upright post 11 is combined with the aluminum gutter 12 through the adapter 18. The adapter 18 is a bracket to lift the aluminum gutter 12. The arch 13 adopts phi 48 galvanized round pipes for supporting the greenhouse film material 20. The aluminum gutter 12 is a closed aluminum profile structure with a hollow cavity in the middle, and has the characteristics of good heat insulation and dew collection prevention. A drain channel 14 is provided on top of the aluminum gutter 12 to collect outdoor rain water. The dew collecting grooves 15 on both sides of the drain groove 14 serve as dew collecting grooves 15 for collecting dew in the greenhouse and fixing the arch 13.

The drainage groove 14 comprises a first bottom plate 141 and side plates 142 connected to two ends of the first bottom plate 141, the side plates 142 extend obliquely upwards to enable the drainage groove 14 to be in a horn mouth shape with the inner part narrow and the outer part wide, each side plate 142 is provided with a film coating fixing groove 143, and the end part of the film coating material 20 is fixed in the film coating fixing groove 143 through a clamping piece 144. The film fixing groove 143 is formed as a groove body with a cross section in a shape of an inner splayed, the clamping piece 144 is of a rectangular sheet structure capable of being clamped in the film fixing groove 143, the film material 20 is firstly placed in the film fixing groove 143, and then the clamping piece 144 is penetrated from the end part of the film fixing groove 143, so that the film material 20 can be fixed.
