WATER GUTTER FOR GREENHOUSES WITH FILM COATING AND GUTTER CONNECTION JOINTS Russian patent published in 2017 - IPC A01G9/14 

FIELD: agriculture.

SUBSTANCE: water gutter includes an upper chute and a lower chute, forming together with sidewalls a tubular-shaped internal cavity. The gutter sidewalls on the outer side are made with a longitudinal ledge equipped with a bead to form a side chute, the upper, lower and side chutes having openings for the liquid discharge. The gutter sidewalls are made inclined from the vertical axis, the openings of the upper chute are equipped with outlet pipes and / or funnels passing through the gutter interior and the opening in the lower chute for connection to storm runoff pipes. The openings of the lower chute are made with outlet pipes connected to the storm drain pipe. The lower gutter chute is made with counter-inclines to the center, forming a V-shaped rib, and the connection joint for mounting the gutter on columns comprises a support with a V-shaped response recess and a detachable retainer made in the form of two symmetrical pads with hitches on the upper edge, embracing the side chute beads and connecting the gutter with the support mounted on the column. The connection joint for fixing the film coating is made in one piece with the upper chute in the form of longitudinal shaped locking-type slots located on the edges of the upper chute.

EFFECT: increasing the gutter rigidity and ensuring the separate supply of precipitation water and condensate to a storm runoff, with preventing atmospheric precipitation falling inside the greenhouse and uncontrolled air exchange with the external environment, improving the performance of a gutter for greenhouses with film coating while reducing the material consumption of its structure.
