Water-saving type drainage tank of citrus culture greenhouse

Abstract

The invention relates to a water-saving type drainage tank of a citrus culture greenhouse. The water-saving type drainage tank is characterized in that a drainage tank is arranged at a concave part ofthe greenhouse along the length direction; the front and back ends of the drainage tank extend out of the front and back end surfaces of an arc-shaped ceiling, and are communicated with a pipeline and a water storage tank via through holes; precipitating and filtering mechanisms are arranged at the parts, close to the pipeline, of two ends of the drainage tank, and each precipitating and filtering mechanism comprises a precipitating and filtering tank and an overflow tank which are communicated via an overflow hole; a sludge collecting tank is arranged under one side of each precipitating andfiltering tank; the upper end of each sludge collecting tank is sealed; a piston rod is arranged in each sludge collecting tank; the lower end of each piston rod is used for opening or closing a bottom opening of each sludge collecting tank through a piston head; and the upper end of each piston rod extends out of the corresponding sludge collecting tank, and each extending part is connected withthe top end of the corresponding sludge collecting tank through a spring. According to the water-saving type drainage tank of the citrus culture greenhouse provided by the invention, by arranging theprecipitating and filtering mechanisms, rainwater can be automatically and primarily filtered so as to avoid blockage and decrease labor intensity.

Description

technical field [0001] The invention relates to rainwater recovery equipment, in particular to a water-saving drainage tank in a citrus cultivation greenhouse. Background technique [0002] The tops of citrus greenhouses or other vegetable planting greenhouses are all arc-shaped, and rainwater is easy to gather at the arc-shaped grooves, and flow into the soil through both ends of the arc-shaped grooves, so that too much water penetrates into the soil locally, which is harmful to plant growth ignore. Many existing greenhouses adopt a drainage channel structure to collect and recycle rainwater. However, due to the long-term accumulation of dust on the top of the greenhouse, it will be deposited on the pipes or in the reservoir after being collected with rainwater, and it needs to be cleaned regularly after a period of time, which is very troublesome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-saving...
