technical field

The invention relates to the technical field of environmental monitoring equipment, in particular to a remote water quality monitoring device and a system thereof.

Background technique

As we all know, the existing water quality monitoring system is generally fixed. The sensor is placed in the water system to be tested, and the electrical control system is placed on the shore. Such a detection device can only detect one location at a fixed point, and it is inconvenient to move. The prior art continues a movable remote water quality monitor capable of remote monitoring of water quality and a detection system thereof.

And yes, most of the monitoring devices in the prior art require manual data supervision, but cannot automatically realize supervision and control, and need to be manned all the time.

And yes, most of the monitoring devices in the prior art require manual data supervision, but cannot automatically realize supervision and control, and need to be manned all the time.

For example, a probe for online water quality monitoring equipment in the prior art, application number CN201720957888.7, discloses a probe for online water quality monitoring equipment, including a probe shell, a conductive circuit and a data storage card, and the left side of the bottom of the probe shell is installed There is a pH sensor, a temperature sensor is installed on the right side of the pH sensor, a turbidity sensor is installed on the right side of the temperature sensor, and a dissolved oxygen sensor is installed on the right side of the turbidity sensor. It is equipped with a mobile rod, data storage card and solar panels, which can break the traditional detection probe mode, realize mobile data collection in the lake surface, and can effectively detect water quality data at different positions and directions on the lake surface, improving the detection efficiency. Functionality and usefulness of the probe. Obviously, this utility model cannot raise and lower the probe device, and cannot collect data of different water depths in the water area, and in water areas with rapid currents, the probe device will sway in the water, which may cause components to enter water due to bumps damage, and it cannot be fixed in place in water.

Obviously, although the monitoring device can monitor the water quality of different water depths in the water area, when it is working, because the depth of the specified water area is uncertain, when using the push rod motor to extend the push rod, it is easy to be overextended. As a result, the collection part collides with underwater obstacles or obstacles in the water, resulting in equipment failure; and the detection equipment is exposed on the water surface, which is not concealed enough, and it is easy to be maliciously damaged after being discovered by environmental pollution producers.
