Abstract
The utility model relates to a drainage water level controller for a farmland subsurface tube. The drainage water level controller comprises a collecting tank, wherein a vertical water level control tube is arranged inside the collecting tank; the bottom of the water level control tube is connected with a water inlet tube extending out of the collecting tank; the water level control tube is provided with a plurality of water outlets thereof from top to bottom at intervals; each water outlet of the water level control tube is provided with a drain plug; and a water outlet tube is arranged at the bottom of the collecting tank. The utility model has the advantages of simple structure, low manufacturing cost, and convenient operation management and maintenance, controls the subsurface tube to drain groundwater by changing the positions of the water outlets of the water level control tube and effectively fulfils the aim of controlling the groundwater level; and besides, a water inlet is easy to connect with the original subsurface tubes laid in a field and only needs laying under the ground so as to be convenient to mount.
Description
Technical field
The utility model relates to a kind of agricultural drain equipment, relates in particular to a kind of farmland hidden tube drainage water level controller.
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 targets such as efficient and rational utilization and management of water resource.China has buried the closed drainage device underground in many regional farmlands, but owing to lack the control corresponding drainage, making the control water discharge technology also be widely used at the end in China, mainly is because control drainage plant is relatively backward, 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 farmland hidden tube drainage water level controller easy to maintenance are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
It comprises collecting-tank, be provided with vertical water level control pipe in the collecting-tank, the water level control pipe bottom is connected with the water inlet pipe that stretches out collecting-tank, be arranged at intervals with a plurality of water level controller delivery ports on the water level control pipe from top to bottom, be equipped with plug on each water level controller delivery port, the bottom of collecting-tank is provided with outlet pipe.
Also be provided with control valve and water meter on the above-mentioned outlet pipe.
Compared with prior art, the utility model has been obtained following technique effect:
1, this utility model is simple in structure, low cost of manufacture, operational administrative and easy to maintenance, change control hidden pipe row underground water by water level control exit position, effectively reach the purpose of control groundwater table, simultaneously, water inlet is easy to connect with the hidden pipe that lay in former field, only need be embedded in underground, easy for installation;
2,, be easy to reach the purpose of controlled water flow break-make and water flow measurement by on outlet pipe, also being provided with control valve and water meter.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-water inlet pipe, 2-water level control pipe, 3-collecting-tank, 4-water level control pipe delivery port, 5-plug, 6-control valve, 7-water meter, 8-outlet pipe.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1, a kind of farmland hidden tube drainage water level controller, it comprises collecting-tank 3, be provided with vertical water level control pipe 2 in the collecting-tank, the water level control pipe bottom is connected with the water inlet pipe 1 that stretches out collecting-tank, is arranged at intervals with a plurality of water level control pipe delivery ports 4 on the water level control pipe from top to bottom, is equipped with plug 5 on each water level control pipe delivery port, the bottom of collecting-tank is provided with outlet pipe 8, also is provided with control valve 6 and water meter 7 on the outlet pipe.
The utility model is embedded in place, hidden pipe outlet field, be connected with the outlet of agricultural drain hidden pipe, the water that closed drain is discharged is introduced water level control pipe, the following outlet of water level control pipe corresponding height is highly blocked in water level control as required, according to law of connected vessels, the farmland groundwater table will be controlled at needs height of water level.The draining of flowing out from water level control pipe imports collecting-tank, measures drain discharge by the water meter that is installed in collecting-tank bottom outlet pipe.
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 outlet that this moment, user plug only allowable was blocked the following water level controller of demand height of water level just can be controlled at groundwater table the height of demand.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, and the exit position of water level control pipe can correspondingly reduce.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.
