Flow guide device for water drainage of saline and alkaline land

Abstract

The invention relates to a flow guide device for water drainage of saline and alkaline land. The flow guide device comprises a water box and filtering tubes, wherein the water box is buried under theground; a plurality of water inlet pipes are fixedly arranged on the top surface of the water box; each water inlet pipe is made of hard materials; each water inlet pipe communicates with the inside of the water box; external screw threads are arranged at the periphery of the water inlet pipe; the distance from the top end of the water inlet pipe to the ground is h; the right side of the bottom end of the water box communicates with a water drainage ditch through a water outlet pipe; each filtering tube is made of hard materials; a scraping plate is fixedly arranged at the bottom end of the opposite side of each of two connecting rods; and each scraping plate is in contact matching with the periphery of the filtering tube. The flow guide device has the advantages that the structure is simple; the use and the operation are convenient and fast; the soil flowing out along with accumulated water is avoided; the phenomenon of water and soil loss is relieved; meanwhile, through the arrangement of the scraping plate, the surface of the filtering tube can be cleaned by the scraping plate; the water drainage influence due to soil accumulation is avoided; through the arrangement of bowl-shaped cases, the scraping plate can be driven by wind power; energy sources are saved; and convenience is brought to users.

Description

technical field [0001] The invention belongs to the field of drainage devices, in particular to a diversion device for drainage of saline-alkali land. Background technique [0002] Most of the existing drainage and diversion devices for saline-alkali land are installed on the ground. The diversion devices occupy a large area, which is easy to affect the cultivation and reduce the cultivated area, and the existing diversion devices are easy to be taken away in part Soil, causing water and soil erosion, affecting later cultivation. Contents of the invention [0003] The invention provides a flow guide device for drainage of saline-alkali land, which is used to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A diversion device for drainage of saline-alkali land, including a water tank and a filter cartridge. The water tank is buried underground. Several water inlet pipes are fixedly installed...
