Description

Technical Field

[0001] The invention belongs to the technical field of rudder hanging arms, and in particular relates to a rudder hanging arm for large ships with high stability and low resistance. Background Art

[0002] The rudder arm is a key component connecting the hull and the rudder. It supports and hangs the rudder structure, allowing the rudder to be stably installed at the stern of the hull to ensure the ship's maneuverability. During the ship's navigation, the rudder arm needs to transmit the torque generated by the steering gear to the rudder so that the rudder can rotate according to the driver's operation. At the same time, it also needs to withstand various forces exerted on the rudder in the water, including hydrodynamic force, steering torque, etc., to ensure that the ship's heading control is accurate and reliable.

[0003] When ships sail in high-latitude areas or go out to sea in cold seasons, the ambient temperature often drops below 0°C, creating conditions for the rudder arm to freeze. Once the rudder arm freezes, its original shape and surface smoothness will change. When water flows through, additional resistance and turbulence will be generated, which will greatly affect the ship's maneuverability. The ship's steering becomes insensitive, the rudder efficiency is reduced, and the difficulty of controlling the course during navigation increases significantly. At the same time, the weight of the ice layer causes the rudder arm to bear additional load, resulting in increased stress on the rudder arm and its connecting components. If the ice is severe, it may even exceed the designed load-bearing capacity of the rudder arm, causing structural damage such as deformation and cracks, which seriously threatens the safety of ship navigation.

[0004] Currently, the method for dealing with ice on the rudder arm is mostly to use high-pressure water guns or ice-breaking equipment to clean it when the ship is docked. However, this method is extremely untimely. As time goes by, the thickness of the ice continues to increase, and the cleaning work becomes more and more difficult. Moreover, cleaning the ice from the outside of the rudder arm can easily damage its surface paint, thereby affecting the quality of the rudder arm. Summary of the Invention

[0020] Compared with the existing technology, the beneficial effects of the present invention are:

[0021] Through the set rudder arm main body, reciprocating lifting mechanism, heating and knocking de-icing mechanism, and heating air supply mechanism, when the ambient temperature is detected to be low enough to cause the rudder arm to freeze, the heating and de-icing work of the rudder arm can be automatically triggered. The rudder arm is heated and the heat is transferred to the surface, reducing the strength and adhesion of the ice layer. When the temperature rises above 0°C, the ice layer gradually melts. Even if it is not completely melted, it will become loose, which is conducive to subsequent knocking and de-icing. The system can also automatically adjust the heating intensity according to the ambient temperature. The lower the temperature, the stronger the heating, so as to ensure the de-icing effect.

[0022] Through the set heating and knocking de-icing mechanism and the positive and negative power supply mechanism, when the ice layer becomes brittle after heating, the knocking device installed inside the rudder arm starts to work and knocks the inner wall of the rudder arm. The knocking force can be transmitted to the ice layer on the surface of the rudder arm, making it easier to break and fall off, thereby effectively removing the formed ice layer and preventing the ice layer from continuing to accumulate. The combination of heating and knocking gives full play to the advantages of both, which is more efficient than a single de-icing method. Compared with using strong external de-icing means when the ice layer is very thick, de-icing from the inside with heating and knocking is more gentle and uniform, which can avoid damage to the surface of the rudder arm caused by strong external de-icing, and is beneficial to maintaining the structural integrity and performance of the rudder arm. At the same time, it can also automatically adjust the knocking force according to the ambient temperature. The lower the ambient temperature, the higher the knocking intensity, thereby ensuring the best de-icing effect.

[0023] Through the set lubricating oil adding mechanism and lubricating oil adding active trigger mechanism, lubricating oil can be automatically added to the connection and installation position of the rudder arm and the rudder stock at intervals to avoid wear and tear of the rudder stock and the rudder arm due to long-term use due to friction and vibration, which may lead to loose connection and displacement of the rudder arm position, affecting the ship's heading stability. When the ambient temperature is low, the heating equipment on the inner wall of the rudder arm is used to compensate for the temperature of the lubricating oil adding process to prevent the lubricating oil from condensing and ensure smooth filling. At the same time, the single filling amount of lubricating oil can be automatically adjusted according to the ambient temperature. The lower the temperature, the more lubricating oil is added at a single time. This is because the metal parts in the corresponding connection seat of the rudder arm shrink at low temperatures, causing the gap to become smaller, and more lubricating oil is needed to ensure lubrication and buffering effects and reduce component wear.

[0041] The active trigger mechanism 6 for adding lubricating oil is fixedly installed inside the rudder arm body 1, and is used to send a start instruction to the lubricating oil adding mechanism 5, and is electrically connected to the PLC controller. The PLC controller is used to send a power adjustment instruction to the active trigger mechanism 6 for adding lubricating oil based on the real-time temperature data fed back by the ambient temperature sensor. The active trigger mechanism 6 for adding lubricating oil includes a trigger shell 61. The inner wall of the trigger shell 61 is rotatably connected to a reciprocating screw 62. The outer wall of the trigger shell 61 is fixedly provided with a reduction motor 63 for driving the reciprocating screw 62 to rotate. The rod wall of the reciprocating screw 62 is threadedly sleeved with a trigger plate 64. A trigger switch 65 arranged opposite to the trigger plate 64 is fixedly installed on the upper side of the inner wall of the trigger shell 61. A limit slider is fixedly installed on the outer wall of the trigger plate 64. The inner wall of the trigger shell 61 is provided with a limit slide groove that matches the limit slider.

[0042] The positive and negative power supply mechanism 7 is fixedly mounted on the inner wall of the rudder arm body 1, and is connected in series to the power supply circuit of the heating, striking and de-icing mechanism 3, and is electrically connected to the PLC controller. The PLC controller is used to send power adjustment instructions to the positive and negative power supply mechanism 7 based on the real-time temperature data fed back by the ambient temperature sensor. The positive and negative power supply mechanism 7 includes a switching shell 71, and a transmission shaft 72 is rotatably connected to the center of the inner wall of the switching shell 71. A driving motor 73 for driving the transmission shaft 72 to rotate is fixedly mounted on the outer wall of the switching shell 71. A forward electric connection block 74 and a reverse electric connection block 75 are symmetrically fixedly mounted on the inner wall of the switching shell 71. The shaft wall of the transmission shaft 72 is fixedly connected to a connecting rod 76, and the end of the connecting rod 76 away from the transmission shaft 72 is fixedly connected to a conductive block 77 arranged corresponding to the positions of the forward electric connection block 74 and the reverse electric connection block 75.

[0043] The operating principle of the present invention is described as follows: an ambient temperature sensor is installed on the ship and close to the position of the rudder arm body 1, and the temperature of the environment in which the rudder arm body 1 is located is monitored in real time. When the ambient temperature sensor detects that the operating environment temperature of the rudder arm body 1 is lower than the threshold value, causing the rudder arm body 1 to have an icing problem, the PLC controller controls the reciprocating lifting mechanism 2, the heating and air supply mechanism 4, and the positive and negative power supply mechanism 7 to work, and the motor rotating assembly 25 drives the rotating shaft 21 to rotate. The reciprocating screw rod segment 22 provided on the rotating shaft 21 is connected with the threaded sleeve of the hollow lifting plate 23, so that the hollow lifting plate 23 can realize reciprocating lifting and moving, thereby driving multiple heating elements. The hot knocking de-icing mechanism 3 moves on the inner wall of the rudder arm body 1, and the hot air blower 41 supplies hot air into the hollow lifting plate 23 through the elastic telescopic tube 42, and then transports it to the hot air head 33 through the extension tube 31 for spraying, so that the hot air acts on the inner wall of the rudder arm body 1, heats the rudder arm body 1, and thus melts the ice layer condensed on the outside of the rudder arm body 1. The air circulation problem caused by the hot air blower 41 here can be solved based on the provided vents 9. Since the top of the rudder arm body 1 will be directly connected to the ship, the vents 9 provided on the rudder arm body 1 and the reinforcement plate 8 can achieve air circulation in the rudder arm body 1;

[0044] The PLC controller synchronously controls the operation of the drive motor 73, and the drive motor 73 drives the conductive block 77 to move continuously in the switching shell 71 through the transmission shaft 72 and the connecting rod 76. When the conductive block 77 contacts the positive electrical connection block 74, the positive power supply circuit of the forcing electromagnetic plate 310 is connected, so that the forcing electromagnetic plate 310 generates the same magnetism as the forced permanent magnet plate 39, thereby providing a magnetic thrust to the push-pull plate 36. The push-pull plate 36 cooperates with the push-pull rod 34 to push the knocking block 35 toward the inner wall of the rudder arm body 1 to impact the rudder arm body 1, providing a knocking force to the rudder arm body 1, and knocking off the ice layer condensed on the outer wall of the rudder arm body 1. When the conductive block 77 moves to the connection position with the reverse electrical connection block 75, the reverse power supply circuit of the forcing electromagnetic plate 310 is connected, so that the forcing electromagnetic plate 310 generates the opposite magnetism to the forced permanent magnet plate 39, thereby providing a magnetic attraction force to the push-pull plate 36, causing the knocking block 35 to move in the opposite direction, thereby The striking block 35 continuously provides a striking force to the rudder arm body 1. By combining heating and striking, their respective advantages can be brought into play, which is more efficient than a single de-icing method. Heating changes the physical properties of ice, and striking directly acts on the ice layer to make it fall off, which can quickly remove the ice layer on the surface of the rudder arm, reducing the time that the ice layer affects the navigation of the ship. It can timely remove the ice layer that has already formed, and can prevent the ice layer from continuing to thicken on the original basis. Once the thickness of the ice layer increases, its weight and adhesion will increase, and the difficulty of removal will also increase significantly. This combination method can be used to deal with the ice layer when it is relatively thin, reducing the difficulty and workload of de-icing. Compared with using strong external de-icing methods when the ice layer is very thick, de-icing from the inside by combining heating and striking is more gentle and uniform, and can avoid damage to the rudder arm surface caused by strong external de-icing, such as scratches and deformation, which is beneficial to protecting the structural integrity and performance of the rudder arm.

[0045] Based on the ambient temperature monitored by the ambient temperature sensor, when the ambient temperature is lower, the PLC controller controls the motor rotating assembly 25, the hot air blower 41 and the drive motor 73 to operate at a higher power, thereby increasing the heating intensity, knocking intensity and processing frequency of the hanging rudder arm body 1, and improving the heating knocking intensity of the entire hanging rudder arm body 1, thereby ensuring the quality and efficiency of the de-icing work;

[0046] The PLC controller and the reduction motor 63 work synchronously. The reduction motor 63 drives the reciprocating screw 62 to rotate. The threaded connection between the reciprocating screw 62 and the trigger plate 64 causes the trigger plate 64 to slowly move in the trigger housing 61 until the trigger plate 64 presses on the trigger switch 65, indicating that the position of the corresponding shaft hole of the connecting seat 10 needs to be filled with lubricating oil. At this time, the PLC controller controls the oil supply pump 54 to work for 60 seconds. The oil supply pump 54 cooperates with the oil supply pipe 51 to transport the lubricating oil in the external oil storage container to the dispersion chamber 52 in the connecting seat 10, and then injects the lubricating oil into the shaft hole of the connecting seat 10 through multiple oil supply grooves 53 to complete the lubricating oil filling. This can prevent the connection between the rudder arm body 1 and the hull and rudder blade from wearing out due to friction, vibration, etc. after long-term use, resulting in loose connection, causing the position of the rudder arm body 1 to shift, and affecting the heading stability of the ship. When the ambient temperature is low, the heating air supply mechanism 4 is operated. At this time, the PLC controller also controls the electric current on the heat exchange coil 55 The control valve 56 opens, allowing a portion of the hot air blown by the hot air blower 41 to be transported to the heat exchange coil 55, heating the oil supply pipe 51 and preventing the lubricating oil from having poor fluidity due to low ambient temperature, which in turn affects stable filling. Specifically, the lower the ambient temperature, the wider the opening of the electric control valve 56, allowing more hot air to be injected, improving heating efficiency and ensuring the fluidity of the lubricating oil. Simultaneously, the PLC controller regulates the operating power of the oil supply pump 54 based on the ambient temperature. The lower the ambient temperature, the higher the operating power of the oil supply pump 54. This allows more lubricating oil to be injected during a single lubricating oil filling process within the fixed 60-second filling time. At low temperatures, the metal components in the connecting seat 10 of the rudder arm will shrink, resulting in a smaller clearance. Smaller clearances require more lubricating oil to fill to ensure good lubrication and cushioning, reducing friction and wear between components. Therefore, increasing the amount of lubricating oil added per filling can ensure the stability of the rudder arm.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
