a paddy field

Abstract

The invention provides a floating bed with a frame structure that can be suspended in water for a long time, and a paddy field equipped with a water lifting device powered by natural energy. The water lifting device lifts water from the outside of the paddy field and sends it into the paddy field. Under the action, the water in the paddy field will seep and flow from the soil and sand in the paddy field from top to bottom and return to the external water area, using the soil, sand and its cultivated organisms to intercept the sludge and bacteria in the water body, Digest the pollutants in the water body and sludge to achieve the purpose of purifying the water body; adjust the ratio of the water level to the air in the lower buoyancy chamber, so that the conversion between the water pool and the dry land can be shown in the upper material chamber, realizing the use of water space, The purpose of creating cultivated land, green land and wetland provides an infrastructure for the sustainable development of human society in harmony with the natural environment.

Description

technical field [0001] The invention relates to a paddy field suspended on the water surface, in particular to the fields of planting organisms on a floating bed with a frame structure, purifying water and sludge, and the like. Background technique [0002] Human social activities and modernization have seriously polluted the natural environment such as air, water, and soil. Excessive development and utilization have destroyed the ecological balance and reduced the limited arable land, green land, and wetland on the earth. It is an inevitable choice for human survival and development to develop and utilize water space to make up for the dwindling cultivated land, green land and wetland. Such as Chinese patent publication number is CN1 063012, has announced a kind of method for planting paddy rice on water, the method for this paddy planting selects bulk density to be less than 500kg / m3, and the chemical material plate that does not pollute water quality is buoyant body, acco...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned various floating objects on the water surface and cultivation schemes are not equipped with a water lifting device to organically combine with the cultivation facilities, and the entire facility structure is not equipped with a function to promote the natural circulation of the water body, so there is no active cleaning of the water body to protect the environment. Function, although the publication number 200920053453.5 is provided with water pipes and water supply devices, its water supply scheme and water flow structure are not intended to promote better self-purification of the water body, and the above scheme uses a specific gravity less than 500kg / m3 or foam materials to make floats , the floats made of this material have poor strength, it is difficult to withstand the invasion of wind and waves and long-term use, maintenance and management are also very difficult, and the application range is small, it is difficult to implement in a large area
