Description
Technical field
This utility model relates to Agricultural Water-Soil Engineering technical field, is specifically related to a kind of controllable draining ditch-water
The combination weir of position.
Background technology
It is the most many that agricultural drain is re-used as a kind of important channel alleviating shortage of water resources contradiction
Area has been applied practice.Many researcheres are pointed out, utilize draining not to be provided only to as water source make
Moisture needed for thing, produces environment simultaneously and minimizes impact.Agricultural drain is to prevent land deterioration, transformation
Salt-soda soil and the important means of flood stain middle-and-low-yielding fields, but, along with the chemical substance such as chemical fertilizer, pesticide uses
The increase day by day of amount, agricultural drain is being played the defence flood saline and alkaline disaster of stain, is being improved the same of middle-and-low-yielding fields effect
Time, also become agricultural nonpoint source pollution thing to enter the prevailing transmission approach of water body, to subsoil water and surface water
Environment all produces totally unfavorable impact.Agricultural drain has for plant growth and irrigates of equal importance
Effect, does not has suitable drainage condition and facility, cannot ensure good crop growth environment.But,
Unsuitable draining not only results in farmland nutrient loss and water environment pollution, but also can cause ground, farmland
The loss of table water, subsoil water or the soil water.Due in agricultural drain containing nutrients such as the nitrogen phosphorus needed for crop,
In shortage of water resources area, can reasonably be recycled as an important water source, thus be alleviated
Shortage of water resources contradiction, alleviates the pollution to downstream water simultaneously.Draining control in agricultural field engineering can be to underground
Water level and groundwater resources effectively regulate and control, and have both played its important function at water-logging drainage in flood season, again
Its water storage function can be comprehensively utilized.Control draining and be possible not only to the on-demand draining of the water regime according to farmland,
Meet to limits the crop demand to moisture, improve rainfall utilization rate, alleviate the pressure of local water scarcity
Power, has the effect improving farming district water ecological environment simultaneously.Therefore, agricultural drain recycles grinding of problem
Study carefully not only to following grain security, and to improving water utilization rate, the water environment that protects the fields etc. all
Tool is of great significance.
In existing known technology, such as Chinese patent: " a kind of emptying gate " (Authorization Notice No.: CN
201495534 U, authorized announcement date: 2010.6.2), it discloses a kind of emptying gate and include being arranged on
Gate slot on water wing, gate body is inserted in described gate slot, gate wood body be dismountable up and down
Lamination, connects for hermetic seal between upper and lower lamination.By adjusting lamination gate quantity, control row
Water level in water farm ditch, realizes farmland water level.This technology is disadvantageous in that: gate is originally
Body is dismountable upper and lower lamination composition, and lamination is very little, it is achieved the not any control to water level, lamination
Too much, operating the most loaded down with trivial details, practical application is the strongest.
For another example Chinese patent: " adjustable agricultural drain water level control weir " (publication number: CN 101078210A
Publication date: 2007.11.28), it discloses a kind of adjustable agricultural drain water level control weir, overfall
Plate is located in gutter, and one termination horizontal direction rotary shaft, the other end is dash weir plate top；Control
Rotating disk connects with vertical direction rotary shaft, and there is horizontal direction truncated cone shape gear vertical direction rotary shaft lower end,
This truncated cone shape gear is mutually twisted with vertical direction angular wheel, vertical direction angular wheel and horizontal direction
Rotary shaft connects；Control the pointer on rotating disk and point to graduated disc；Nut rotating disk and tension reinforcement pass through screw
Occlusion, tension reinforcement lower end connects friction brake.This technology is disadvantageous in that: actuating device
Have been at underground, be easily generated fault and be difficult to maintenance, simultaneously as under the gate of rotary shaft setting
Edge, the moment of torsion produced during starter is big, and the material of equipment, production etc. are required height.
Accordingly, it is desirable to provide the combination weir of a kind of controllable gutter water level, by the design of two shoe brake plates,
Any control to gutter water level, and combination weir easy maintenance simple to operate can be realized.
Utility model content
