Description

The utility model relates to technical means used to control the operation of tread protection systems for steel hulls of ships and ships.

Known reference electrode zinc type "Rainbow" ESU-RA [1, p. 7], which is designed for installation in water, including sea water. ESU-RA reference electrode includes: plastic case, zinc electrode, measuring cable, cable lug. The zinc electrode is electrically connected to the measuring cable and installed in a plastic housing. For connection to the terminal block, the measuring cable is terminated with a cable lug.

This reference electrode has the following disadvantages:

high cost;

the ship's crew cannot make such an electrode on their own;

the junction of the measuring cable with the cable lug is not protected from the external environment.

The closest to the proposed utility model is the zinc reference electrode ESU-1 "Mendeleevets" [2, p. eight]. This device includes: plastic housing, zinc electrode, measuring cable, cable lug, heat-shrinkable tube, plate (nameplate), label. The zinc electrode is electrically connected to the measuring cable. The measuring cable is terminated with a cable lug. The junction of the measuring cable and the cable lug is insulated with a heat-shrinkable tube.

This device has the following disadvantages:

high cost;

the ship's crew cannot manufacture such an electrode on their own.

The technical result of the proposed utility model is to simplify its design, reduce labor and material costs in the manufacture of the reference electrode.

The technical result is achieved by the fact that a reference electrode is proposed, including an electrode, a measuring cable soldered to the electrode, a cable lug soldered to the free end of the measuring cable, a heat-shrinkable tube insulating the junction of the measuring cable and the cable lug, characterized in that the electrode is made of galvanized steel.

The design of the proposed device is shown in Fig. one.

The device contains an electrode made of galvanized steel 1; a measuring cable 3 is soldered to the electrode, while the place of soldering 2 is protected by VK 9 glue; a cable tip 4 is soldered to the free end of the measuring cable 3, while the soldering point is isolated with a heat-shrinkable tube 5.

The operation of the device is as follows

The reference electrode using a cable lug is connected to a measuring device - a millivoltmeter;

millivoltmeter with the help of an additional measuring cable, equipped with a clamping contact, is attached to the ship's bulwark;

the reference electrode is immersed in sea water to a depth of 0.5-1 m, while the distance between the reference electrode and the ship's hull should not exceed 2 m;

turn on a portable millivoltmeter and take readings of the device (at least three single readings), while the time interval between taking readings is 5 s;

for effective operation of the protective protection, the readings of the millivoltmeter should be in the range of (-250) ÷ (+50) mV.

The proposed device is advisable to use on any marine ships and vessels for periodic monitoring of the operation of the protector protection of the hulls of ships and ships.

The proposed utility model is illustrated by the drawing of Fig. one.

The designations in Figs. one:

1 - electrode made of galvanized steel; 2 - place for soldering the measuring cable, protected with VK 9 glue; 3 - measuring cable; 4 - tip of the measuring cable; 5 - heat-shrinkable tube.
