[0002] A rudder angle transmitter is a device that converts the steering and angle of the rudder blade into electrical signals and sends them out. Its working principle is based on the process of converting mechanical motion into electrical signals. This process is particularly important in ship engineering because it involves the ship's heading control and navigation.

[0003] Existing rudder angle transmitters are directly fixed on the ship's steering gear equipment, which is inconvenient for the installation and maintenance management of the power equipment data acquisition transmitter, and inconvenient for maintenance personnel to quickly inspect the ship's steering gear and transmitter, which is time-consuming and labor-intensive, and delays the normal launching operation of the ship. Summary of the Invention

[0004] The purpose of the present invention is to provide a 360-degree rudder angle transmitter to solve the above-mentioned defects caused by the prior art.

[0005] The 360-degree rudder angle transmitter includes a device shell, a sealing plate seat is fitted on one side of the device shell, an electrical connector is connected through one side of the sealing plate seat, a positioning mechanism is provided on one side of the interior of the device shell, and the positioning mechanism is used to install multiple groups of electrical components in a sub-shell, so that the electrical components can be easily removed from the interior of the device shell, reducing the difficulty of replacing and disassembling the electrical components. A transceiver mechanism is provided on the other side of the interior of the device shell, and the transceiver mechanism converts mechanical motion into electrical signals. The rudder angle transmitter makes the navigation control of the ship more intelligent.

[0006] Preferably, the positioning mechanism includes an inner device box, a fastening hole, a fin plate and a guide rod. The interior of the device shell is connected through the guide rod, the tail end of the guide rod is connected to the interior of the device shell, fastening holes are opened at equal intervals on one side of the device shell, and the bottom end of the inner device box is fitted with a fin plate.

[0008] Preferably, the transceiver mechanism includes a data turntable, a connecting rod, a gear pair, an inner device box, a sampling potentiometer, a power supply filter, an information transceiver module and a single-chip microcomputer. The data turntable is installed on the outside of the connecting rod, the tail end of the connecting rod is connected to one of the gear pairs, the other side of the gear pair is connected to the input end of the sampling potentiometer, the power supply filter is installed inside the inner device box, a single-chip microcomputer is provided inside the inner device box, one side of the single-chip microcomputer is connected to the input end of the information transceiver module, and the single-chip microcomputer is installed inside the inner device box.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The voltage range of the sampling potentiometer is 0-5V. Since the rudder angle changes in two directions, 2.5V is defined to correspond to 0 rudder angle.

[0029] The practical application of this 360-degree rudder angle transmitter includes the following tasks:

[0030] Step 1: During use, the sampling potentiometer 14, the power filter 15, the information transceiver module 16 and the single-chip computer 17 are sequentially installed inside the inner device box 9, one side of the inner device box 9 is connected through the guide rod 13, and the connecting rod 5 is sequentially connected to the sealing plate seat 3 and the other set of gears in the end gear pair 8, and the gears in the gear pair 8 at the input end of the sampling potentiometer 14 are connected, and then the bolts are inserted into the fastening holes 10 to connect and position the inner device box 9 and the device housing 1, and the device housing 1 is contacted with the sealing plate seat 3, and locked by the fastener 6;
