Problems solved by technology

[0003] At present, there are still some problems in farmland drainage, such as: lack of farmland water level monitoring system or insufficient monitoring; drainage is not timely
Due to the large seasonal and spatial differences in rainfall, when sudden rainstorms and waterlogging occur frequently, the drainage process of farmland often has a hysteresis effect; due to the influence of some traditional agricultural development ideas, many Local agricultural management personnel pay more attention to agricultural irrigation issues, and have not discussed drainage issues in depth, which will make the status of farmland drainage projects even more unfavorable

Abstract

The invention discloses a hydraulically driven automatic drainage system for farmland in hilly areas. Required water level: When the buoy rises, the straight rod connected with the buoy also rises, driving the upper copper plug to block the through hole, and the lower copper plug also goes up, the drain pipe is opened, and the water level in the shaft Descending, the pontoon descends, and correspondingly the gate rises to open the water. Compared with the prior art, when there is too much rainfall or the farmland is invaded by a large amount of external water, the device can timely and effectively self-drain the excessive accumulated water in the farmland to prevent the crops from being flooded and causing waterlogging. At the same time, the device can artificially set the control depth of the farmland water layer according to the conditions of the crops, and does not need to be manually guarded, thereby greatly improving the drainage efficiency. The design of this structure is reasonable and practical, and it is easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a hydraulically driven automatic drainage system for farmland in hilly areas. Background technique [0002] The autumn forest area in my country has sufficient rainfall, so rice is planted in hilly areas, but rice has high water level requirements, and the water volume requirements for each stage of rice are also very high. Whenever there is a heavy rain, the farmland always accumulates a lot of water, which will cause the rice to be flooded and the yield to drop. At this time, farmers will dig channels for drainage. After the water is discharged to a water level suitable for rice growth, the channels must be filled to restore the original appearance of the fields. [0003] At present, there are still some problems in farmland drainage, such as: lack of farmland water level monitoring system or insufficient monitoring; drainage is not timely. Due to the large seasonal and...
