Description

A kind of field drainage control system

Technical field

The invention belongs to the Agricultural Water-Soil Engineering technical field, be specifically related to a kind of field drainage control system.

Background technology

American-European countries carries out agricultural drain by underdrainage pipe network system, by the unlatching of computer control emptying gate.In area, China network of waterways, the agricultural drain mouth is normally dug according to the farming needs temporarily, and the subject matter that these field drainage mouths exist has: the one, dig when needing temporarily, and time-consuming; The 2nd, can not effectively control the farmland water level; The 3rd, when taking away a large amount of silt during draining, increased the pollution load of N, P, cause large-scale pollution of area source.In a word, ubiquitous ridge in farmland and field drainage mouth can not effectively be controlled the farmland water level at present, also do not bring into play due effect in the control widespread pollution from the overuse of fertilizers and pesticides in rural area.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, a kind of drainage control system that can effectively control the farmland water level that is directly installed on the field is provided.

The object of the present invention is achieved like this: a kind of field drainage control system, and at the other water tank that is provided with of ridge, described water tank is provided with water inlet by a side in field, and the bottom surface of described water inlet is a little less than the field face, and the top of described water inlet and the top of described water tank are contour;

The bottom of described water tank is provided with delivery port, and described delivery port links to each other with drainage pipe;

Be provided with floating drum in the described water tank; Described floating drum links to each other with lid on being arranged on described delivery port by gentle rope.

In order to make the positive upper end work of floating drum at delivery port, positioner for floating drum also is set in the field drainage control system of the present invention: be provided with the stationary magazine creel that is fixed on the bottom surface around the described delivery port, the slightly larger in diameter of described stationary magazine creel is in the diameter of described floating drum; The inside of described stationary magazine creel and described water tank internal run-through, the water in the water tank can be stablized the inside that flow into stationary magazine creel.

Adjust the length of gentle rope for convenience, thereby realize the control draining in field, an end of described gentle rope ties up on the lid, and the other end passes the inside of described floating drum, ties up on the fixed block at described floating drum top.

For as required, make things convenient for the water or the reserve part water in emptying field, can be provided with movable fragment of brick in described water inlet, the top of described movable fragment of brick is higher than described field face.

Field drainage control system of the present invention, when the field water level surpassed design water level, the cistern water level that is communicated with it was raised, thereby this moment floating drum thereupon lifting pulling lid open the outfall draining; When drawdown, buoyancy reduces, and lid relies on dead weight to close delivery port, stops draining.Realize draining under the different control water level in field by regulating rope length between floating drum and the lid; When field water needs emptying, remove movable brick, shorten gentle rope length or take away lid and floating drum freely flows out water.

Beneficial effect of the present invention is:

1, field drainage control system of the present invention can be according to the need water and the drainage requirement of different farmlands and farmland different times, to adjust rope long in good time, water level in the control main box, realize the farmland water level, thereby on time and space, satisfy of the requirement of the different growing stage of Different Crop and crop to water level, realized the automatic control of field drainage, improved the utilization rate of rainwater resource and N, P nutrient, the man power and material who has saved agricultural drain drops into, and has reduced the N in the agricultural drain, the P pollution to gutter and downstream water body;

2, the construction costs of field drainage control system of the present invention and maintenance cost are low, and compact conformation, easy for installation need not power, simple to operate, and the pollution control effect is obvious, safe and reliable, are easy to large tracts of land and promote;

3, of the present invention applying not only can produce good economic benefit, also will produce remarkable social benefit.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the mode by embodiment is elaborated to technical solution of the present invention, but protection scope of the present invention is not limited to described embodiment.

Embodiment 1

A kind of field drainage control system, at the other water tank 1 that is provided with of ridge, described water tank 1 is provided with water inlet 2 by a side in field, and the bottom surface of described water inlet 2 is a little less than field face 3, the top of the top of described water inlet 2 and described water tank 1 is contour, and water can flow freely in the water tank; The bottom of described water tank 1 is provided with delivery port 4, and described delivery port 4 links to each other with drainage pipe; Be provided with floating drum 5 in the described water tank 1; Described floating drum 5 links to each other with lid 7 on being arranged on described delivery port 4 by gentle rope 6; Be provided with the stationary magazine creel 8 that is fixed on the bottom surface around the described delivery port 4, described stationary magazine creel 8 adopts pvc pipe, and the slightly larger in diameter of described stationary magazine creel 8 is in the diameter of described floating drum 5; A water inlet is respectively opened in the both sides, front and back of described stationary magazine creel 8, makes the inside and described water tank 1 internal run-through of described stationary magazine creel 8, the water in the water tank 1 to stablize and flows in the stationary magazine creel 8; One end of described gentle rope 6 ties up on the lid 7, and the other end passes the inside of described floating drum 5, ties up on the fixed block 9 at described floating drum 5 tops; Described water inlet 2 places are provided with movable fragment of brick 10, and the top of described movable fragment of brick 10 is higher than described field face 3.
