Safety and environmental-protection device for water drainage of paddy field

Abstract

The invention discloses a safety and environmental-protection device for water drainage of a paddy field, and belongs to the field of rice environmental-protection planting. The lower part of a water drainage pipe of the safety and environmental-protection device extends into a tubular hole of a pedestal; a transverse flange plate of the water drainage pipe is fixedly arranged on the upper surface of the pedestal; a water outlet in the lower end of the water drainage pipe communicates with the tubular hole; the tubular hole is connected with a water passage which is constructed in soil inside the paddy field; and the water drainage pipe is sleeved by a ring-shaped floating body. A matching surface of the ring-shaped floating body is matched with the outer surface of the upper surface part of the water drainage pipe, so that the ring-shaped floating body can slide on the upper surface part of the flood-discharge pipe, and can open or close a water drainage pipeline while sliding up and down. The safety and environmental-protection device for water drainage of the paddy field disclosed by the invention is compact and reasonable in structure, is convenient to manufacture and use, is high in degree of automation, is good in effect of automatically draining water and keeping water level in the paddy field, does not need people to watch during automatic water drainage, automatically closes the water drainage channel to keep water level while a water surface in the paddy field is lower than set irrigating level, is safe and environmental-protection water drainage equipment of the paddy field, and is necessary equipment for automatically managing the paddy field.

Description

technical field [0001] The invention relates to a paddy field drainage safety and environmental protection device in the field of rice environmental protection planting. Background technique [0002] The drainage of the present paddy fields all adopts opening gaps on the field ridges to release water. In order not to discharge too much water in the paddy fields, people are required to watch when the water is released. During heavy rains, the water in the paddy fields surges, often washing away the ridges of the paddy fields, causing great losses to agricultural production. In order to ensure the production safety of rice fields, we have invented a safety device that can automatically drain water after long-term research. . Contents of the invention [0003] The purpose of the present invention is to provide a safety and environmental protection device and method for automatically managing and maintaining the water level in the paddy field, protecting the ridge from the i...
