The invention relates to the field of irrigation and water conservancy engineering, in particular to a drainage collection and water quality real-time monitoring device which is characterized by comprising a control board, a driving board, an executing mechanism, a pipeline, a collection container, a water quality monitoring module and energy equipment. The control panel comprises a main control chip and an Internet of Things communication module connected to the main control chip; the Internet of Things communication module is connected to the main control chip; the signal input end of the main control chip is connected to the water quality monitoring module, and the signal output end of the main control chip is connected to the driving plate; the driving plate is in signal connection with the executing mechanism; the executing mechanism comprises a sampling valve and a submersible pump; the submersible pump is arranged at the pipeline water inlet end; the collecting container is communicated with the pipeline; the sampling valve is arranged between the pipeline and the collecting container and is used for controlling water passing of the collecting container; the water quality monitoring module is arranged at the opening of the collection container; the energy device is used for supplying power to the control board and the driving board. The device is high in precision, high in automation degree and high in water sampling efficiency.

Description

technical field [0001] The invention relates to the field of farmland water conservancy engineering, in particular to a device for collecting drainage and real-time monitoring of water quality. Background technique [0002] The sources of agricultural non-point source pollution are scattered and numerous, the discharge is greatly affected by time and space, and the discharge process is characterized by dispersion, concealment and complex path. One of the important contents of prevention and treatment. [0003] The existing mainstream water sample collection devices at home and abroad are as follows: [0004] 1. Bottom water sampling device [0005] 1. Equipment introduction: rely on artificial throwing and use the sampler's own weight to make it sink to the bottom of the water body, and pull it through ropes and use the sampler's own weight to open and close. [0006] 2. Disadvantages: [0007] (1) It is difficult to control the sampling depth by only relying on its own ...

AI Technical Summary

Problems solved by technology

[0007] (1) It sinks to the bottom of the water body only by its own weight, it is difficult to control the sampling depth, and it has a certain degree of blindness

[0008] (2) Opening and closing is achieved only by rope traction and the weight of the sampler itself. The effect of opening and closing is not good, and it is easy to cause the sediment to fall during the lifting process.

[0009] (3) No remote operation

[0013] (1) It is labor-intensive and time-consuming, and the buffering effect is not obvious when taking water

[0014] (2) When the equipment enters the water, it will cause turbulence in the water body and cause agitation, which will cause the water sample to be turbid. When collecting drainage water samples in the entire farmland, the efficiency is low and it will have a certain impact on the quality of the sampled water.

[0015] (3) No remote operation

[0018] 1. The accuracy is low, and there are problems such as sediment falling during the sampling process and sample turbidity due to turbulent water flow.

[0019] 2. The degree of automation is weak, it is difficult to collect water samples remotely, it is difficult to avoid manual operation, low cost performance, high labor costs, and high cost of water sample collection

[0020] 3. The efficiency of water collection is low. Most of the products on the market adopt the "one bag multiple times" water collection method, which has low flexibility when applied to multiple water collection.
