Abstract
The utility model relates to a water level control tube for the drainage of farmland subsurface water. The tube comprises a tubular casing, wherein a top cover and a bottom cover are mounted at the top and the bottom ends of the tubular casing respectively, a flexible telescopic tube section is arranged in the middle of the tubular casing, a pull rod is arranged at the top of the flexible telescopic tube section inside the tubular casing, a water outlet is arranged on the tubular casing at the flexible telescopic tube section, and a water inlet is arranged on the tubular casing between the flexible telescopic tube section and the bottom cover. The utility model has the advantages of simple structure, low manufacturing cost, as well as convenient operation, management and maintenance.
Description
Technical field
The utility model relates to a kind of equipment that is used to control the farmland groundwater table, relates in particular to a kind of water level control pipe for farmland subsurface water control.
Background technology
The control draining is modern a kind of novel farmland water management technology.Its objective is that the groundwater depth with the whole growing of plant is controlled at some values.Make the underground water of plant different growing bury the concentration difference by drainage management, reach and prevent and treat widespread pollution from the overuse of fertilizers and pesticides in rural area effectively, improve crop yield, prevent and treat the salinization of soil and the efficient and rational targets such as management of water resource of utilizing.The control water discharge technology also is widely used at the end in China, mainly is because control drainage plant is relatively backward, and it is economical inadequately, and using neither be very convenient.
The utility model content
The purpose of this utility model is to address the above problem and a kind of simple in structure, low cost of manufacture, operational administrative and water level control pipe for farmland subsurface water control easy to maintenance are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
It comprises tubular outer casing, the tubular outer casing top is provided with top cover, the tubular outer casing bottom is provided with bottom, be provided with the flexible telescopic tube section in the middle of the tubular outer casing, flexible telescopic tube section top is positioned at tubular outer casing inside and is provided with pull bar, the tubular outer casing at flexible telescopic tube section place is provided with delivery port, and the tubular outer casing between flexible telescopic tube section and the bottom is provided with water inlet.
Be provided with joint between the tubular outer casing of above-mentioned flexible telescopic tube section and its bottom.
Above-mentioned pull bar is provided with scale.
Compared with prior art, the utility model has been obtained following technique effect:
1, this utility model is simple in structure, by the change control hidden pipe row underground water of pulling pull bar control bellows exit position, effectively reaches the purpose of control groundwater table;
2, by design on pull bar scale is arranged, the Different Crop different growing is provided some reference values, be convenient to user's use.
Description of drawings
Fig. 1 is the utility model sectional view.
Wherein: 1-pull bar, 2-top cover, 3-flexible telescopic tube section, 4-delivery port, 5-joint, 6-water inlet, 7-bottom.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of water level control pipe for farmland subsurface water control, it comprises tubular outer casing, the tubular outer casing top is provided with top cover 2, and the tubular outer casing bottom is provided with bottom 7, is provided with flexible telescopic tube section 3 in the middle of the tubular outer casing, flexible telescopic tube section top is positioned at tubular outer casing inside and is provided with pull bar 1, design has scale on the pull bar, and the tubular outer casing at flexible telescopic tube section place is provided with delivery port 4, and the tubular outer casing between flexible telescopic tube section and the bottom is provided with water inlet 6.Be provided with joint 5 between the tubular outer casing of flexible telescopic tube section and its bottom.The tubular outer casing diameter generally can be got 10～15cm, so the plant area area is very little, the water inlet interface connects with the hidden pipe that lay in former field, only need be embedded in underground, easy for installation.
The utility model is embedded in place, hidden pipe outlet field, connect mutually with the closed drain outlet, the water that closed drain is discharged enters the tubular outer casing bottom, enter in the telescoping tube then, change the telescoping tube exit position by pull bar, according to law of connected vessels, the field water level is with controlled, and the field water yield and field drainage amount are with controlled.
Plant is in the seedling phase, and transpiration quantity is little, and water requirements of crops is few, the root system of crop is also very short, phreatic water level can remain on more shallow buried depth, and the root system of crop can not steeped, and can not make crop failure, and the moisture content that has kept the field, utilize follow-up breeding time for plant, control higher groundwater table, also can prevent the loss of fertilizer in the soil moisture, improve utilization rate of fertilizer, reduced the pollution of area source that agricultural drain causes.Desired minimum bury of groundwater difference of Different Crop seedling phase is determined according to the root length of crop.The user only need spur pull bar and made the position of telescoping tube outlet higher this moment, just can reach the requirement of controlling groundwater table.Follow-up breeding time, the growth along with the root system of crop will guarantee that the root system of crop is not steeped, and desired underground water buries concentration and strengthens, from the corresponding reduction in the exit position of telescoping tube.In the plant growth later stage, be subjected to stain that crop is not had much the influence.So bury of groundwater can be reduced to a certain degree again.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
