Description
Technical field
The present invention relates to environmental monitoring technologies, in particular to a kind of dry land rainwash collection device.
Background technique
Farmland soil erosion, agricultural non-point source pollution and farmland nutrient loss are current China's agricultural production and Agro-ecology ring
Protect faced serious problem in border.And agricultural surface runoff is the main carriers for influencing pollutant and nutrient loss.Therefore, right
The research and monitoring of agricultural run-off are always the important research content in agriculture environmental protection field.Diameter flow collector is farmland research
In an essential device.
China carries out the agricultural compound including nitrogen and starts late with the research of the loss of surface runoff, especially exists
Research in each basin and regional scope, in terms of monitoring rainwash pollutant loss law by the continuous in-situ of long-term many years
It is less.Traditional method focuses mostly in by microscopic mode test or field runoff experimental plot technique study area source pollutants
Transportion and transformation, rainwash collection need to set runoff collecting pit, this to build occupied area increase, destroy original soil ring
Border, and it is time-consuming and laborious.In addition, rainfall has uncertainty, rainfall duration and rainfall intensity will affect silt in rainwash and contain
Amount and pollutant concentration, conventional method be easy to cause silt silting collecting pit mouth, or the runoff collected is caused not have monitoring generation
Table.For the uncertainty of natural precipitation change in time and space, the features such as flow path surface changes is generated, it is necessary to design a kind of suitable
Agricultural surface runoff device is acquired together in field in-situ monitoring, it is dirty convenient for face source in more scientific and reasonable research agricultural surface runoff
The loss law of dye.
Summary of the invention
In view of the deficiencies in the prior art, it collects and fills the purpose of the present invention is to provide a kind of dry land rainwash
It sets.
The technical solution adopted in the present invention is as follows:
A kind of dry land rainwash collection device, including triangular-notch weir, covering plate, adapter and the receipts being arranged in earth's surface
Collect bottle；
The triangular-notch weir open upper end is simultaneously covered by the covering plate, and the both ends of the triangular-notch weir in the horizontal direction are opened respectively
Equipped with water inlet and water outlet；The water outlet is provided with the flow monitoring device for monitoring flow；The water outlet
Less than the water inlet；The water outlet is identical as the water inlet open height；
The water outlet is connected by the adapter with the receiving flask of upward opening；
Overflow port is offered in the bottle wall of the receiving flask upper end；The overflow port is lower than the water outlet in order to liquid
It overflows in time, prevents liquid reflux from generating interference to flow monitoring.
Further, receiving flask inner cavity upper end, which is additionally provided with, is divided into two-part grid for the receiving flask inner cavity
Net can prevent the impurity such as large particle or dry branches and fallen leaves to be mixed into runoff device in this way；The aperture plate is lower than the overflow port.
Further, the water outlet is additionally provided with pollution parameters sensor, can be monitored in real time in runoff in this way
Pollutant data.
Also further, the water outlet and the water inlet width ratio are between 1:5~1:20.
Still further, the water outlet and the water inlet width ratio are 1:10.By above-mentioned width ratio, cooperate flow
Monitoring device such as flow monitoring sensor is acquired the accuracy highest of runoff.
The present invention provides a kind of simple runoff collecting devices that can accurately calculate soil diameter flowing liquid product, make soil diameter
The monitoring of flow liquid has the characteristics that at low cost, manufacture and easy for installation, easy implementation, result are reliable.The device can be scientific and effective
Acquisition agricultural surface runoff, convenient for subsequent monitoring and prevent the rainwash bring nutrient loss in farmland, be conducive to agriculture
The loss of surface runoff of field area source pollutants is studied.
Detailed description of the invention
Fig. 1 is dry land rainwash collection device overall structure diagram；
Fig. 2 is the schematic top plan view on Fig. 1 intermediate cam weir；
Detailed description of the invention: earth's surface 1；Triangular-notch weir 2；Water inlet 2.1；Water outlet 2.2；Flow monitoring device 2.3；Covering plate 3；Turn
Connector 4；Receiving flask 5；Aperture plate 6；Overflow port 7.
Specific embodiment
The present invention is described in further detail with specific embodiment with reference to the accompanying drawings of the specification.
As shown in Fig. 1, a kind of dry land rainwash collection device, including be arranged in earth's surface 1 triangular-notch weir 2, cover
Plate 3, adapter 4 and receiving flask 5；
2 open upper end of triangular-notch weir is simultaneously covered by covering plate 3, as shown in Fig. 2, the both ends of triangular-notch weir 2 in the horizontal direction point
Water inlet 2.1 and water outlet 2.2 are not offered；The flow monitoring device for monitoring flow is provided at water outlet 2.2
2.3；Water outlet 2.2 is less than water inlet 2.1；Water outlet 2.2 is identical as 2.1 height of water inlet；
Water outlet 2.2 is connected by adapter 4 with the receiving flask 5 of upward opening；
Overflow port 7 is offered in the bottle wall of 5 upper end of receiving flask；Overflow port 7 is lower than water outlet 2.2.
Preferably, 5 inner cavity upper end of receiving flask, which is additionally provided with, is divided into two-part aperture plate 6 for 5 inner cavity of receiving flask；Aperture plate 6
