When the water-entering detection probe is conducted in water, a current loop is formed, the direction of the current loop is opposite to the movement direction of electrons, current flows from a positive electrode to a negative electrode outside a battery, and electrons flow from the negative electrode to the positive electrode, so that the electrons are accumulated near the positive electrode probe and react with positive ions of a coating with positive charges on the surface of the probe to cause falling or damage of the coating, namely deplating/deplating, so that the protection effect on a metal substrate of the probe is lost, the corrosion of the probe is caused, the function is lost, and the like.
In one embodiment, the housing 2 includes: a top cover 21 and a base 22. Wherein, the base 22 has a placing groove 221, the placing groove 221 is used for placing the detecting device 3, and the base 22 is hermetically connected with the top cover 21 to form a containing space.
In an embodiment, the bottom of the placing groove 221 is formed with a through hole 222, and the through hole 222 communicates the accommodating space and the outside of the housing 2. The detecting device 3 extends to the outside of the housing 2 through the through holes 222, and at least three through holes 222 are provided.
Fig. 2A is a schematic structural diagram of a detection apparatus 3 according to an embodiment of the present disclosure, and fig. 2B is a cross-sectional view taken along a-a direction in fig. 2A, where the detection apparatus 3 includes at least two probes 31 and an active metal rod 32. One end of the probe 31 passes through the through hole 222 and extends to the outside of the housing 2, one end of the active metal rod 32 passes through the through hole 222 and extends to the outside of the housing 2, and the other end of the active metal rod 32 is electrically connected with the other end of the probe 31. In one embodiment, the surface of the probe 31 is plated with a corrosion-resistant alloy or an inert metal, and the active metal rod 32 is a magnesium rod or a zinc rod.
Fig. 3 is a schematic structural diagram of another detection apparatus 3 provided in the embodiment of the present application, and the probe 31 includes a positive probe 311 and a negative probe 312. The other end of the positive electrode probe 311 is electrically connected to the other end of the active metal rod 32.

In an embodiment, taking a fish finder as an example, the number of the probes of the fish finder is three, namely, the positive electrode pin, the signal pin and the negative electrode pin, and the probe substrate is stainless steel, so the stainless steel is selected, because the conventional metals are Fe, Cu, Al and alloys thereof, the Al and the alloys thereof are oxidized to form a compact aluminum oxide film, the aluminum oxide cannot conduct electricity, the strength of the aluminum alloy is poor, the Cu and the alloys thereof are nonferrous metals, copper oxide is formed after oxidation, and the conductivity of the copper oxide is greatly reduced, which affects the detection of the normal conduction of the device. Therefore, the stainless steel which is cheap and commonly used is selected as the base material. The surface of the probe is electroplated with corrosion-resistant alloy or inert metal through an electroplating process, and in order to avoid deplating and corrosion of the probe, a Zn rod is respectively connected with the positive pin and the signal pin through metal wires, and meanwhile, the Zn rod and the pins are required to be ensured to be in contact with the water surface together.
At this time, when conducting, Zn is more active than Fe, and is better than the metal of the probe 31, and reacts with surrounding electrons, so that Zn is oxidized, the metal of the probe is protected, and deplating, corrosion and rusting of the metal of the probe are avoided.
In one embodiment, the Zn rod can be a hidden design, that is, when contacting water, the Zn rod can be ensured to contact water to form a loop, and the Zn rod is invisible in appearance, so that after the Zn rod is oxidized and corroded for a long time, white zinc oxide cannot be seen, and the strength and corrosion resistance of the probe are protected. The probe is made of stainless steel, and other metal materials can be used.
The probe adopts an electroplating process as an example, and the method is still effective to electrochemical corrosion of passivation, acidification and other processes.
The number of the probes is only three, and the number of the probes can be only two or more than three, and at least one positive pole or signal line and one negative pole or ground line are required to be ensured.
The Zn rod is merely an example, and may be an active metal such as a Mg rod, but it is necessary to ensure that the Zn rod can be oxidized relatively easily, and the relatively easy degree is to ensure that the Zn rod is at least more active than the metal of the probe 31 substrate.
It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
