The device generally comprises a main instrument and a sensor connected with the main instrument, wherein the sensor is divided into a rod sensor and a plane sensor. The plane sensor has less extension out of the ship bottom plate during measurement, so that the problem that the rod sensor is easy to collide in a shallow water area or a fishing net area is solved, and the plane sensor is widely concerned.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

With the advent of large ships and the demand for measuring the speed and range of ships, electromagnetic odometers have been widely used on ships as a device for measuring the speed and range of ships. The functions of the electromagnetic log include: measuring and displaying the speed and range, calibrating the speed measuring field, sending range and speed information to the outside, and the like. The components in the electromagnetic log comprise a main instrument and a sensor for providing a magnetic field, wherein the sensor is divided into a rod sensor and a plane sensor. The plane sensor has less extension out of the ship bottom plate during measurement, so that the problem that the rod sensor is easy to collide in a shallow water area or a fishing net area is solved, and the plane sensor is widely concerned.
The plane sensor and the bottom plate of the ship are usually installed through a water gate set, and the plane sensor extends out of the bottom plate of the ship by more than 10mm through a center hole of the water gate set to measure the speed. The water gate group is used for separating the opening of the ship cabin and the opening of the ship bottom plate by closing the flashboards in the water gate group when the plane sensor is replaced, so that the plane sensor is replaced. However, since the water gate set directly contacts with the seawater in the using process, the sealing performance of the gate plate can be affected by impurities in the seawater and the corrosivity of the seawater, and the sealing effect is reduced. In addition, along with the increase of the service life of the water gate group, the friction force of the sealing contact surface is increased, and the sealing effect of the gate plate is also affected along with the increase of the closing force of the gate plate, so that the water gate group needs to be maintained or replaced regularly.
