Description

Technical Field

[0001] The utility model relates to the technical field of steering devices, and more specifically to a marine steering gear with a rotary steering device. Background Art

[0002] There are currently two types of marine steering gears: one is a fully hydraulic type, which uses a fully hydraulic steering gear to control the direction of the ship's rudder. The steering gear is installed in the front cab of the ship, and the rudder is at the rear of the ship. The pump outputs through hydraulic pipelines to the front, rotates the steering gear to make the oil circuit reach the rear of the ship, and pushes the hydraulic cylinder to form a rudder rotation. The span between the front and the rear is relatively long. The disadvantages of this are that there are noises during steering, response time, heavy feel, and lag; the other is a fixed electric control type, which uses an electric conversion switch (normally closed or normally open) to control the direction of the ship's rudder. Its principle is formed by the conversion of high and low pressure oil, and directly supplies oil to the hydraulic cylinder at the rear of the ship through the pump to form the rotation direction of the rudder. There is no noise, but the electric control switch directly controls through the normally open or normally closed state of electricity, and the speed cannot be controlled, and the stability performance of the ship's rudder is not good. Therefore, we propose a marine steering gear with a rotary steering device. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a marine steering gear with a rotary steering device to solve the problems existing in the above-mentioned background art.

[0004] The utility model provides the following technical solutions: A marine steering gear with a rotary steering device includes a driving control console, a rotary steering wheel, an electronic steering gear, a regulated power supply, a proportional current amplifier board, a rudder angle indicator, a 485 signal rudder angle feedback control module, a rotary integrated control box, a left electromagnetic directional valve, a right electromagnetic directional valve, and a steering gear actuator. One end of the rotary steering wheel is connected to the steering shaft of the electronic steering gear through an elastic coupling. The output end of the electronic steering gear is electrically connected to the rotary integrated control box. Electromagnets are provided on both the left electromagnetic directional valve and the right electromagnetic directional valve. The output end of the rotary integrated control box is electrically connected to the electromagnets on the left electromagnetic directional valve and the right electromagnetic directional valve. The rudder angle indicator is electrically connected to the rotary integrated control box. The steering gear actuator includes a left hydraulic cylinder and a right hydraulic cylinder.

[0005] Further, the left electromagnetic directional valve is connected to the left hydraulic cylinder, and the right electromagnetic directional valve is connected to the right hydraulic cylinder.

[0006] Further, the proportional current amplifier board and the 485 signal rudder angle feedback control module are installed inside the rotary integrated control box.

[0007] Further, the angle of the rudder angle indicator is controlled by signals through the 485 signal rudder angle feedback control module.

[0008] Further, an emergency steering wheel is installed on the control console.

[0009] Further, the external power supply of the regulated power supply is DC 24V 6A.

[0014] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and the shipborne steering gear with a rotating follow-up type of the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0015] Embodiment 1:

[0016] As Figure 1-2As shown, the marine steering gear with a rotary steering device includes a driving console, a rotary steering wheel, an electronic steering gear, a regulated power supply, a proportional current amplifier board, a rudder angle indicator, a 485-signal rudder angle feedback control module, a rotary integrated control box, a left electromagnetic reversing valve, a right electromagnetic reversing valve, and a steering gear actuator. One end of the rotary steering wheel is connected to the steering shaft of the electronic steering gear through an elastic coupling. The output end of the electronic steering gear is electrically connected to the rotary integrated control box. Electromagnets are provided on both the left electromagnetic reversing valve and the right electromagnetic reversing valve. The output end of the rotary integrated control box is electrically connected to the electromagnets on the left electromagnetic reversing valve and the right electromagnetic reversing valve. The rudder angle indicator is electrically connected to the rotary integrated control box. The steering gear actuator includes a left hydraulic cylinder and a right hydraulic cylinder. The left electromagnetic reversing valve is connected to the left hydraulic cylinder, and the right electromagnetic reversing valve is connected to the right hydraulic cylinder. The proportional current amplifier board and the 485-signal rudder angle feedback control module are installed inside the rotary integrated control box. The angle of the rudder angle indicator is signal-controlled through the 485-signal rudder angle feedback control module. An emergency steering wheel is installed on the driving console. The external power supply of the regulated power supply is DC 24V 6A.

[0017] In this embodiment, the main function of the rudder angle indicator is to indicate the rotation direction and angle of the ship's rudder blade. By displaying the angle of the ship's rudder blade, the rudder angle indicator helps the crew control the direction of the ship and ensures that the ship can accurately turn according to the instructions. The regulated power supply provides a stable power supply for the steering device to prevent damage to the steering device caused by voltage fluctuations or interference. The 485-signal rudder angle feedback control module can prevent the formation of current loops through electrical isolation and signal isolation, avoid electrical interference and equipment damage, and at the same time avoid signal crosstalk and mutual interference, improving stability and reliability. The proportional current amplifier board receives the control signal and amplifies it to the current required by the electromagnet of the electromagnetic reversing valve, thereby driving the electromagnetic reversing valve.

[0018] To sum up, as Figure 1-2 shown, for this marine steering gear with a rotary steering device, when the crew adjusts the ship's rudder, the crew rotates the rotary steering wheel. The rotary steering wheel drives the steering shaft of the electronic steering gear, causing the electronic steering gear to indicate the proportional current amplifier board and the 485-signal rudder angle feedback control module to work and compare. The working output current is applied to the electromagnets on the left electromagnetic reversing valve and the right electromagnetic reversing valve. When the rotary steering wheel rotates to the left, the electromagnet on the left solenoid valve obtains the corresponding current, pushing the spool of the left solenoid valve to supply medium oil to the left hydraulic cylinder, so that it reaches the angle required by the ship's rudder. Conversely, when the rotary steering wheel rotates to the right, the electromagnet on the right solenoid valve obtains the corresponding current, pushing the spool of the right solenoid valve to supply medium oil to the right hydraulic cylinder, so that it reaches the angle required by the ship's rudder. When the rotation stops, the rudder remains in a static state, which is more convenient and flexible than using normally open or normally closed switches to control the electromagnetic reversing valve to control the direction of the ship's rudder, and at the same time has stable reliability.
