Automatic gate and time-phased water level and water sample collection composite device

Abstract

The invention discloses an automatic gate and a time-phased water level and water sample collection composite device. The device comprises an automatic gate system, a water level flow monitoring system, a time-phased water sample collection system, a control system, a solar panel, a rainwater sensor, a containing box, a vertical supporting rod and a connecting wire. According to the present invention, the device is started by the rainwater sensor; by automatically and flexibly controlling a gate to be opened and closed, and utilizing a multi-fork pipe and an electromagnetic valve, the time-phased water sample collection is achieved, so that the time-phased water taking is accurately controlled. The device has the advantages that the water samples in different time periods can be collectedinto different sampling bottles, the water level information in each time period can be monitored at the same time for flow calculation, and the water quantity and the water samples can be obtained atthe same time; the gate can be flexibly adjusted to store and drain water, the manual operation is little, and the management cost is low; the water samples remaining in a water inlet pipe can be flushed out in a pressurized manner, the mutual influence of sampling in different time periods is avoided, and meanwhile the sampling bottles can be spontaneously sealed when being filled with the watersamples.

Description

technical field [0001] The invention relates to an automatic gate and a time-divided water level and water sample collection composite device, belonging to the field of farmland water conservancy engineering and the field of water environment monitoring equipment. Background technique [0002] With the gradual improvement of point source pollution control capabilities, the severity of non-point source pollution has become increasingly prominent, especially agricultural non-point source pollution is the most common and serious. Agricultural non-point source pollution mainly refers to the soil particles, nitrogen, phosphorus, pesticides and other organic or inorganic substances in the farmland in the process of precipitation or irrigation in agricultural production activities, through farmland surface runoff, farmland drainage and underground seepage. , A large amount of pollutants enter the water body and form water environment pollution. It has the characteristics of decent...

Problems solved by technology

In agricultural areas, gates are currently used to intercept drainage ditches for water storage, and the opening and closing of gates needs to be done manually. If it is not opened in time when it rains, drainage will be affected

[0005] At present, there is no system and device that combines the gate, water level, and water sample collection on the market, but the gate can be organically combined with the water level and water sample collection device, so that the flow rate at the corresponding time can be obtained while collecting water samples to meet the needs of hydrological and water quality analysis. requirements and the need for measured data for calibration and verification of hydrological models
