A staged farmland hard ecological drainage channel

Abstract

The invention discloses a staged farmland hard ecological drainage channel. The staged farmland hard ecological drainage channel comprises a foundation; a through channel is arranged on the front surface of the foundation; inner-layer transverse plates are mounted on both the left and right sides of the notch of the through channel; and a water channel is mounted at the front end of the through channel. In the staged farmland hard ecological drainage channel, sliding chutes are formed in the front surfaces of an inclined block and a vertical plate; built-in sliding chutes are formed in the left and right sides of the sliding chutes for the sliding of cross sliding blocks; a transverse body is welded between two groups of cross sliding blocks; a floating plate is connected with the transverse body; when the liquid level in the through channel rises, the floating plate is driven to rise; a planting barrel mounted at the inner middle part of the floating plate is used for planting plants;the bottom end of the planting barrel takes the shape of a hollow sieve for soilless culture; the bottom end of the floating plate takes the shape of a cotton block and is used for playing a role inlifting when the liquid rises, so that the plants planted on the planting barrel are prevented from being submerged by the liquid and the plants can absorb certain micro elements in the water so as toplay a role in purifying the water primarily.

Description

technical field [0001] The invention belongs to the technical field of ecological drainage channels, in particular to a staged hard ecological drainage channel for farmland. Background technique [0002] With the increase and continuation of environmental protection in our country, the pollution of industrial wastewater and urban domestic sewage has been effectively controlled, and the treatment rate of rural domestic sewage has also increased year by year. Farmland non-point source pollution has become an important source of water environment pollution today. [0003] The function of the drainage channels involved in farmland is introduced above. Under the existing technology, the first type of drainage channels is realized by manual excavation. However, manual excavation channels do not have the ability to improve water quality and can only be used to introduce water. For use in farmland, the second type is machine excavation, and the outside of the drainage canal is fille...

Problems solved by technology

[0003] The function of the drainage channels involved in farmland is introduced above. Under the existing technology, the first type of drainage channels is realized by manual excavation. However, manual excavation channels do not have the ability to improve water quality and can only be used to introduce water. For use in farmland, the second type is machine excavation, and the outside of the drainage canal is filled with cement to prevent the drainage canal from becoming loose after a long period of use, and soil will flow into the drainage canal, and it does not have the ability to purify water. Effect, the third category is the purification of water quality drainage channels, which are usually realized through ecology, using plants, the design of the drainage channel, and adding fillers at the bottom of the drainage channel. There is a disadvantage in this category, planting plants in the drainage channel The water level of the drainage channel will rise and fall. This is not considered in the third category. The plants are submerged in water. In addition, when installing the drainage channel, it is necessary to fix the structure around the distribution channel. The traditional anchors Or the cement is fixed, the anchor is not suitable for long-term use, and the addition of cement is not suitable for later maintenance. Different structures are used in the application to improve the shortcomings of the anchor
