Embodiment Construction

[0013] A hard plastic water baffle (4) is adopted to be connected as a whole with a floating block (3) made of a material with extremely strong buoyancy. Water retaining plate (4) is packed in the water retaining plate groove (10) that duroplastics is made, as the criterion that can slide freely up and down, and plastics is made aqueduct (6) and canal wall (8) and connects firmly. The purpose of this is to be able to automatically irrigate and save water——

[0014] The water retaining plate (4) and the water release depend on the paddy field water (2), that is: when the water in the paddy field water (2) reaches a predetermined water level depth, the buoyancy of the water is used to support the floating block (3), and the water retaining plate (4) must rise along water retaining plate groove (10), until blocking aqueduct (6), canal water (9), stop flow and save water.

[0015] When the water level of the paddy field water (2) surrounded by the ridge (1) decreased, the floatin...

Abstract

The invention belongs to the field of rice field irrigation, and particularly relates to a rice field water-saving irrigation automatic control device. An aqueduct (6) is made of plastics and is firmly connected with a ditch wall (8); the other end of the aqueduct (6) is provided with a water baffle groove (10) made of rigid plastics; a water baffle (4) is arranged in the water baffle groove (10) and is subject to being capable of freely sliding up and down; a floating block (3) made of materials with an extremely strong floating force is connected with the water baffle (4) made of the rigid plastics; the floating block (3) always rises or lowers along with the depth of rice field water; when the water level of the rice field water (2) surrounded and stored by ridges (1) lowers, the floating block and the water baffle (4) necessarily sink due to self weight and being subjected to the action of gravity, so that the rice field water (2) is supplemented by ditch water (9) from a water outlet (5) through the aqueduct (6); when the preset water level is reached, the floating block (3) is floated by buoyancy of water; and the water baffle (4) necessarily rises along the water baffle groove (10) until the aqueduct (6) and the ditch water (9) are blocked to stop water flow and save the water, so that the conditions of automatic irrigation and no spilling are realized under an unattended condition, and therefore an irrigation network of farmland develops higher water-saving efficiency, and the purposes of automatic irrigation and water saving can be satisfied.

Description

Technical field: [0001] The invention belongs to the field of paddy field irrigation, in particular to an automatic control device for paddy field water-saving irrigation. Background technique: [0002] At present, the following methods are mostly used for paddy field irrigation in rice planting areas: manpower pumping water or truck water, which is time-consuming and laborious; mechanical pumping water wastes energy and is costly; places with canal irrigation conditions can directly release water for irrigation, but it is often overflowing, causing water resources a great waste. Invention content: [0003] The purpose of the present invention is to provide an automatic control device for paddy field water-saving irrigation. [0004] The technical solution adopted by the present invention to solve the technical problem is: make the water guide pipe (6) with plastic, connect it firmly with the canal wall (8), and the other end is provided with a water retaining plate groov...
