Description

Isolated water sample acquisition water intake and drainage system device

Technical Field

The utility model relates to a drainage technical field is advanced in the water sample collection especially relates to an isolated water sample collection drainage system device.

Background

At present, on-line water quality monitoring in the market mainly comprises the steps of placing water quality sensors (dissolved oxygen, ammonia nitrogen, nitrite, water temperature and other sensors) into water for a long time, monitoring the change of relevant parameters in water quality in real time, determining the water quality of a test water area, and then taking targeted measures. However, in general culture water, microorganisms, algae, excrement of fishes and shrimps, food feeding and the like cause extremely complicated water conditions, and cause pollution and even damage to sensitive membrane systems with fragile sensors. In addition, because the aquatic plant mostly needs electrical equipment such as oxygen-increasing machine to provide sufficient oxygen for aquatic products to and the existence of other interference sources such as place periphery has high-voltage line, often because ground protection does not in place causes phenomenons such as electric leakage, causes the sensor to be disturbed, above circumstances lead to the sensor to reduce and measure the accuracy. Even directly leading to sensor damage, resulting in measurement failures and loss of significance of measurement result data. At present, a duty maintenance mode is generally adopted for the situation, and for a large-batch deployed aquaculture base, the workload is quite large, so that the cost is high.

In order to avoid the electric interference of the water body, the related art also designs a detection device to pump water out of the water body for detection, but the following problems still exist.

1. After the water suction pump is stopped, water flows back through the water inlet pipeline.

2. The position of the water inlet pipe is too high, so that a large amount of air is mixed in the water inlet process, the components of the sampling water body are changed, and the measuring significance is lost.

3. The flow velocity of the inlet water flow is too large, silt particles in the inlet water flow impact the sensor membrane system, and the membrane system is damaged after a long time.

4. Although the water inlet part adopts a filtering device, the filtering device cannot be used too finely, otherwise, the turbidity index is seriously deviated from the actual water body, so that microorganisms in water are possibly enriched in the sensor part, a sensitive membrane system of the sensor is polluted and even damaged, and the detected data is inaccurate.

5. Because the oxygen content (dissolved oxygen value) in water is very low at night or under the condition of unbalance of algae microorganisms in the natural aquaculture water body, the oxygen content in the water is seriously low, and fish and shrimp die. Therefore, under a specific condition, the measurement time is too long, the oxygen content of the collected water sample in the water storage container and the oxygen in the air are fully combined to increase the oxygen content of the water sample, so that the measurement value is inaccurate, and if the measurement value is used as a basis for controlling the oxygen increasing equipment, the situation that the oxygen dissolved in the actual water body is too low and the oxygen increasing equipment is not opened can be caused, so that the serious economic loss of oxygen deficiency death of fishes and shrimps can be caused.

6. When water quality monitoring device is deployed in the field (breeding fishponds are mostly in the field), under the condition of sunshine insolation, the temperature of the water storage container rises, and the water temperature is raised when water storage is caused, so that the temperature acquired by the temperature sensor is higher than the actual natural water body, and the data needing temperature compensation is caused to generate large deviation.
