Combined water delivery pipeline for water conservancy irrigation

Abstract

The invention belongs to the technical field of water conservancy irrigation, and discloses a combined water delivery pipeline for water conservancy irrigation, which comprises a chassis, supporting blocks are symmetrically and fixedly mounted at the top of the chassis, fixing discs are arranged at the tops of the supporting blocks, connecting holes are formed in the middles of the fixing discs, first rotating rings are movably mounted on the fixing discs, and the first rotating rings are movably mounted on the supporting blocks. The back face of the fixing disc is rotationally connected with three rotating shafts which are distributed in a circumferential array mode relative to the circle center of the connecting hole. A plurality of rotating shafts are arranged on the base, blocking pieces are fixed to the rotating shafts, bristles are arranged on the outer surfaces and the side walls of the blocking pieces, the blocking pieces are combined together to form a circle, and first protruding blocks are fixed to the outer side walls of the blocking pieces. A first circular ring is arranged on the outer side wall of the first rotating ring; through mutual cooperation of the first electric telescopic rod, the second electric telescopic rod, the first circular ring and the like, the opening degree of a channel between the blocking pieces is controlled, then the flow can be adjusted according to the actual irrigation requirement, and therefore the applicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy irrigation, in particular to a combined water delivery pipeline for water conservancy irrigation. Background technique [0002] Develop irrigation and drainage, adjust regional water conditions, improve farmland water conditions, prevent and control drought, waterlogging, salt, and alkali disasters, and promote comprehensive science and technology for stable and high agricultural production. Farmland water conservancy is generally called irrigation and drainage abroad. Farmland water conservancy involves water Mechanics, civil engineering, agronomy, soil science, as well as hydrology, meteorology, hydrogeology, and agricultural economics. Improve soil and fertilize, expand land use, in order to achieve the purpose of high and stable agricultural production. [0003] When the existing farmland water conservancy irrigation water pipes are used, the water pipes are often blocked by various...

AI Technical Summary

Problems solved by technology

[0003] When the existing farmland water conservancy irrigation water pipes are in use, the water pipes are often blocked by various dirt in the water, and the water pipes leak after a long time of blockage; and at present, the staff often use the water delivery pipes when performing water conservancy irrigation , but the existing farmland irrigation pipes are generally exposed within 0.5 meters of the ground, which affects the normal operation of agricultural machinery and farmland cultivation, and is easy to collide and damage the pipes, so it needs to be improved
