Description

Technical Field

[0001] This utility model relates to the field of electric ships, and more particularly to a rudder plate for connecting a controller and a propeller. Background Technology

[0002] In electric ships, a linkage is typically used to connect the propeller and the controller. The operator can control the direction of the propeller by rotating the linkage through the controller. The controller contains a chip that drives the propeller to rotate. The operator can control the start, stop and speed of the propeller through interactive keys and the chip.

[0003] In the prior art, such as the integrated high-power-density underwater direct-drive permanent magnet drive motor propeller disclosed in Chinese Patent Application No. 202321999999.6, a specific structure of a propulsion system for an electric ship is disclosed, and the working principle is explained. It uses a rudder-shaped central outer shell as a connecting rod, replacing the conventional round rod-shaped connecting rod. When rotating this connecting rod, the shape of the rudder plate can be used to guide airflow and reduce resistance. However, for the heat dissipation of the controller, it still relies on an external cooling fan for air cooling. But the application scenarios of propeller propellers are mostly humid, moisture-laden, or dusty aquatic environments. During fan operation, external moisture and dust can easily penetrate the fan's interior and the controller housing, easily causing the fan to jam and short-circuit, or even causing electrical components to be damaged by moisture.

[0017] Example 1: The rudder plate for connecting the controller and the thruster provided in Embodiment 1 of this utility model, such as Figures 1 to 4 As shown, the system includes a rudder body 1 and a control box 2. The control box 2 is fixed to the top of the rudder body 1. A water pipe 11 is vertically arranged inside the rudder body 1. A water inlet 12 is opened on the lower side of the rudder body 1. The water inlet 12 is connected to the water pipe 11. A water outlet 13 is opened on the upper side of the rudder body 1. The water outlet 13 is connected to the water pipe 11. A heat exchanger 3 is installed inside the control box 2. A cooling water inlet 21 is opened on the control box 2. The cooling water inlet pipe 31 of the heat exchanger 3 passes through the cooling water inlet 21 and connects to the water outlet 13. A cooling water outlet 22 is opened on the control box 2. The cooling water outlet pipe 32 of the heat exchanger 3 extends out from the cooling water outlet 22.

[0018] The rudder plate provided in Embodiment 1 of this utility model serves as a carrier connecting the controller and the thruster. Specifically, the lower part of the rudder plate body 1 is fixedly connected to the thruster (such as the underwater motor in the prior art document). The controller is directly fixed inside the control box 2 (which also contains a power supply) and electrically connected to the thruster. In actual operation, the user interacts with the controller inside the control box 2 to control the thruster's rotation speed. The user controls the thruster's propulsion direction by rotating the rudder plate body 1. The controller generates heat during this process. In this embodiment, a heat exchanger 3 (equipped with a self-priming pump) is installed inside the control box 2. The self-priming pump of the heat exchanger 3 is used to heat the rudder plate. Water in the lower part of the main body 1 (the part extending underwater) is drawn into the heat exchange core of the heat exchanger 3. The cooling part of the heat exchanger 3 dissipates heat from the heat-generating components in the control box 2. Specifically, the cooling water enters the water pipe 11 inside the rudder body 1 from the inlet 12, and then flows out from the outlet 13 and directly into the cooling water inlet pipe 31. The cooling water exchanges heat with the cooling medium (preferably a cooling pipe in this embodiment, specifically a cooling pipe wrapped around the outside of the heat-generating controller, and the cooling medium in the cooling pipe after heat exchange with the cooling water dissipates heat from the controller; the layout between the cooling pipe and the controller is existing technology and will not be described in detail here) in the heat exchanger 3. The cooling medium continuously dissipates heat from the controller, and the cooling water is finally discharged from the cooling water outlet 22 to the outside of the control box 2. Unlike existing technologies, which require ventilation openings on the control box 2 to ensure heat dissipation, this embodiment eliminates the need for ventilation openings, preventing moisture from entering the control box 2 and causing a short circuit in the controller.

[0019] The rudder plate for connecting the controller and the propeller provided in Embodiment 1 of this utility model solves the problem in the prior art that water vapor can easily enter the propeller controller of electric ships and affect the operation of the controller. It can reduce the impact of water vapor entering the controller on the operation of the controller.

[0020] In this embodiment, a control conduit 14 is vertically arranged inside the rudder body 1; a thruster mounting slot 15 is provided on the rudder body 1; a control conduit inlet 151 is opened on the inner wall of the thruster mounting slot 15; the control conduit inlet 151 is connected to the control conduit 14; and the outlet of the control conduit 14 is connected to the control box 2. The control wires and power supply wires of the thruster are both run through the control conduit 14 inside the rudder body 1 and are finally connected to the control box 2, avoiding direct exposure of the wires to the outside and direct contact with water.

[0021] In this embodiment, the rudder plate body 1 is also provided with several fixing holes 16; the fixing holes 16 are set perpendicular to the water pipe 11; the fixing holes 16 penetrate the water pipe 11; the fixing holes 16 are set vertically below the water inlet 12. The rudder plate body 1 needs to be rigidly connected to the thruster. When the thruster is working, the propeller rotation will generate lateral vibration, and the water flow impact will generate lateral force. Ordinary fixing holes are only opened on the surface of the rudder plate body 1, and the bolt force is concentrated on the surface of the rudder plate body 1. Long-term vibration is prone to cracking around the hole and loosening of the connection. In this embodiment, fixing holes 16 are set in the direction perpendicular to the water pipe 11 (i.e., horizontally penetrating the water pipe 11) to connect the thruster, and the rigid structure of the water pipe 11 is used to ensure the stability of the position of the fixing holes 16. The two openings after the water pipe 11 is penetrated form a connection structure that restricts a straight line at two points, avoiding changes in the connection angle between the thruster and the rudder plate body 1. Since the fixing holes 16 are set below the water inlet 12, they will not affect the normal entry of water into the water pipe 11 and the upward movement of water into the control box 2.

[0022] In this embodiment, a rudder hinge 4 is also included; a hinge mounting groove 17 is provided on the rudder body 1; a first rotating hole 171 and a second rotating hole 172 are vertically opened in the rudder body 1; the first rotating hole 171 is located vertically above the second rotating hole 172; the first rotating hole 171 and the second rotating hole 172 are coaxial; the first rotating hole 171 and the second rotating hole 172 communicate with the hinge mounting groove 17; the rudder hinge 4 is disposed in the hinge mounting groove 17; the rudder hinge 4 is rotatably fixed in the first rotating hole 171 and the second rotating hole 172 by a vertically extending rotating rod. The rudder hinge 4 is fixed to the hull. When the rudder body 1 rotates relative to the rudder hinge 4, the thruster fixed on its surface will rotate accordingly (i.e., rotate relative to the hull), thereby changing the direction of thrust. The rotation axis of the rudder body 1 relative to the rudder hinge 4 is the hole axis of the first rotating hole 171 and the second rotating hole 172. In this embodiment, the rudder hinge 4 with a rotating rod set in the vertical direction is used to fix the rudder hinge 4 so that the upper end of the rotating rod of the rudder hinge 4 is inserted into the first rotating hole 171 and the lower end of the rotating rod of the rudder hinge 4 is inserted into the second rotating hole 172.

[0023] In this embodiment, the direction of water flow is the front side; the front side of the cross-section of the rudder plate body 1 perpendicular to the water pipe axis is arc-shaped and convex, while the rear side gradually narrows away from the front side and forms a sharp edge; the arc-shaped convex contour of the front side and the narrowing contour of the rear side are transitioned by a smooth curve. In the prior art, such as the upper side of an aircraft wing, the arc-shaped convex design of the front side makes the water flow smooth along the arc surface and maintain a laminar flow state when it comes into contact with the rudder plate, avoiding the formation of local low-pressure vortices due to the separation of water flow caused by sharp corners or abrupt changes in shape; compared with the large area of ​​turbulent wake formed by the rear side of the traditional cylindrical or square cross-section, which generates a reverse drag force, the rear side of the rudder plate body 1 of this embodiment narrows into a sharp edge, so that the water flow after passing through the rudder plate will converge and separate at the sharp edge along the narrowed contour line, avoiding the generation of a wide wake vortex.

[0024] In summary, this utility model provides a rudder plate for connecting a controller and a propeller, relating to the field of electric ships. It includes a rudder plate body and a control box; the control box is fixed to the top of the rudder plate body; a water pipe is vertically arranged inside the rudder plate body; a water inlet is opened on the lower side of the rudder plate body; the water inlet connects to the water pipe; a water outlet is opened on the upper side of the rudder plate body; the water outlet connects to the water pipe; a heat exchanger is installed inside the control box; a cooling water inlet is opened on the control box; the cooling water inlet pipe of the heat exchanger passes through the cooling water inlet and connects to the water outlet; a cooling water outlet is opened on the control box; and the cooling water outlet pipe of the heat exchanger extends from the cooling water outlet. The rudder plate for connecting the controller and the propeller provided by this utility model solves the problem in the prior art where water vapor easily enters the propeller controller of an electric ship, affecting the controller's operation, and can reduce the impact of water vapor entering the controller on its operation.
