Water conservancy irrigation closed system

Abstract

The invention relates to a water conservancy irrigation closed system which includes a water channel for water diversion and a water blocking mechanism installed on the water channel. The water channel communicates with a crop pond for planting crops; the water blocking mechanism includes a sliding chute fixedly arranged in the water channel, a flashboard slidably matched in the sliding chute, a control box arranged on the water channel, and a supporting shaft rotatably supported on the control box; an unwinding reel is coaxially fixed to the supporting shaft, a drawstring is wound on the unwinding reel, one end of the drawstring is fixed to the unwinding reel, the other end of the drawstring is fixed to the flashboard, and the supporting shaft is connected with a driving device; and a control device is arranged between the crop pond and the water blocking mechanism. By arranging the control device between the crop pond and the water blocking mechanism, when the water level in the croppond reaches a certain height, the control device can control the flashboard of the water blocking mechanism to automatically lower to block water, and convenience during use is improved.

Description

technical field [0001] The invention relates to the technical field of irrigation systems, in particular to a water conservancy irrigation closed system. Background technique [0002] When irrigating landscape garden facilities such as farmlands, nurseries, flower beds, and flower ponds, sprinkler irrigation and flood irrigation are usually used, and the water will completely cover the irrigated area. In areas rich in water conservancy resources, people build ditches to bring water from rivers and lakes into areas that need to be irrigated, and build gates on ditches to control the amount of water inflow, so as to achieve the purpose of quantitative irrigation. During the irrigation process, when the water accumulates to a certain amount in the irrigation area, the gate needs to be closed to prevent the water from overflowing to the outside. [0003] At present, the patent document with the authorized announcement number CN108049373A discloses a wetland diversion gate, whic...

AI Technical Summary

Problems solved by technology

[0004] If the above-mentioned wetland diversion gate is applied to the irrigation of farmland and landscape facilities, if the gate is to be closed after the water level reaches a certain height, there must be staff guarding the gate. When the water level reaches a certain irrigation height, The staff can close the door leaf by operating the handle or the motor to block the irrigation water, which is troublesome to use
