In an exemplary embodiment of the present utility model, referring to fig. 1 and 2, the conductive detection and protection device 100 includes a liquid containing cavity 110 and an electrode protection circuit. The liquid-holding chamber 110 is used for holding a conductive solution, which in this embodiment includes, but is not limited to, an aqueous solution.
The electrode protection circuit comprises a control unit 121, two electrodes and a power supply 122, wherein the power supply 122 supplies power to the electrode protection circuit.
The two electrodes are a first electrode 123 and a second electrode 124, respectively, the first electrode 123 and the second electrode 124 are disposed in the liquid containing cavity 110, and the first electrode 123 and the second electrode 124 are disposed at intervals. When the first electrode 123 and the second electrode 124 are not in contact with the conductive solution, the first electrode 123 and the second electrode 124 are not conducted; when the first electrode 123 is in contact with the second electrode 124 and the conductive solution, the first electrode 123 and the second electrode 124 are in conduction through the conductive solution. In this embodiment, the first electrode 123 and the second electrode 124 are disposed at the same height of the liquid-containing chamber 110, so that the first electrode 123 and the second electrode 124 can be simultaneously contacted with the conductive solution.
In this embodiment, the first electrode 123 and the second electrode 124 are made of a corrosion-resistant conductive material. The anti-corrosion conductive material can be made of any one or more of platinum material, gold material, carbon material and silver material.
In this embodiment, referring to fig. 2, the first electrode 123 and the second electrode 124 are disposed on the inner wall of the liquid-containing chamber 110, so that the first electrode 123 and the second electrode 124 are in contact with the conductive solution in the liquid-containing chamber 110.
The control unit 121 is directly electrically connected to the first electrode 123 such that the first electrode 123 is energized.

When the first electrode 123 and the second electrode 124 are in contact with the conductive solution, the control unit 121 supplies power to the first electrode 123 according to a preset period, so that the time for the first electrode 123 to perform electrolytic reaction with the second electrode 124 and the conductive solution in the power-on state is significantly shortened, the electrolysis of the first electrode 123 and the second electrode 124 in the conductive solution is significantly slowed down, and the corrosion of the first electrode 123 and the second electrode 124 is reduced. The duration of the preset periods is set by the control unit 121, for example, 3s or 6s or 9s or the like for each preset period.
For example, in the case where the first electrode 123 and the second electrode 124 are simultaneously contacted with the conductive solution, if the duration of the preset period is 3s, the control unit 121 continuously supplies power to the first electrode 123 every 3s, relative to the control unit 121, the corrosion rate of the first electrode 123 and the second electrode 124 may decrease by more than 20 times, that is, when the preset period is 3s, the service lives of the first electrode 123 and the second electrode 124 may be prolonged by more than 20 times. Therefore, the timer 129 is used for supplying power to the first electrode 123 periodically, so that the corrosion rate of the first electrode 123 and the second electrode 124 can be remarkably reduced, and the service lives of the first electrode 123 and the second electrode 124 can be prolonged.

The first electrode 123 and the second electrode 124 are disposed at the same height of the liquid containing chamber 110, and the height is calculated from the bottom of the liquid containing chamber 110. The heights of the first electrode 123 and the second electrode 124 in the liquid containing cavity 110 represent the water level, and when the first electrode 123 and the second electrode 124 are connected, the water level of the conductive solution in the liquid containing cavity 110 represents at least the water level corresponding to the first electrode 123.
The voltage sampling module 125 is disposed between the control unit 121 and the first electrode 123, one end of the voltage sampling module 125 is electrically connected to the control unit 121, and the other end is connected to the first electrode 123. The voltage sampling module 125 is configured to collect voltage data of the first electrode 123, and the voltage sampling module 125 outputs the collected voltage data to the control unit 121, and the control unit 121 determines whether the first electrode 123 and the second electrode 124 are turned on according to the magnitude of the voltage data.
A voltage dividing resistor 126 is further disposed between the control unit 121 and the first electrode 123, and the voltage of the first electrode 123 is divided by the voltage dividing resistor 126.
The voltage of the first electrode 123 when not connected to the second electrode 124 is referred to as a threshold voltage, and the collected voltage of the first electrode 123 is referred to as a connection voltage. When the first electrode 123 and the second electrode 124 are conducted through the conductive solution, the conductive solution has an impedance, so that the conducting voltage is less than the threshold voltage after being divided by the conductive solution.
The control unit 121 compares the obtained turn-on voltage with a threshold voltage, when the turn-on voltage is smaller than the threshold voltage, the control unit 121 determines that the first electrode 123 is turned on with the second electrode 124, and the level of the conductive solution in the liquid containing cavity 110 is equal to the height of the first electrode 123 and the second electrode 124, or the level of the conductive solution is higher than the height of the first electrode 123 and the second electrode 124. When the turn-on voltage is equal to or similar to the threshold voltage, the control unit 121 determines that the first electrode 123 and the second electrode 124 are not turned on, and the water level of the conductive solution in the liquid containing cavity 110 is below the height of the first electrode 123 and the first electrode 123.
In this embodiment, the voltage sampling module 125 includes a sampling unit and a digital-to-analog converter, the sampling unit is configured to collect a level signal of the first electrode 123, the sampling unit outputs the collected level signal to the digital-to-analog converter, the digital-to-analog converter converts the level signal into voltage data, the level signal is an analog signal, and the voltage data is a digital signal.
In this embodiment, a filter circuit is further disposed between the voltage sampling module 125 and the first electrode 123, and the filter circuit is configured to filter the level signal. Specifically, the filter circuit includes a first resistor 127 and a first capacitor 128, where the first resistor 127 is connected in parallel with the first circuit, and the first capacitor 128 is grounded, the first resistor 127 is electrically connected to the first electrode 123, and the first resistor 127 and the first capacitor 128 form an RC low-pass filter circuit.
