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 so that the rudder can be stably installed at the stern of the hull to ensure the ship's maneuverability. During the navigation of the ship, the rudder arm needs to transfer the torque generated by the steering gear to the rudder so that the rudder can turn 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 a ship is sailing in high latitudes or going 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 is frozen, 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 is significantly increased. At the same time, the weight of the ice layer causes the rudder arm to bear additional loads, resulting in increased stress on the rudder arm and its connecting parts. If the ice is severe, it may even exceed the designed load-bearing capacity of the rudder arm, causing deformation, cracks and other structural damage, which seriously threatens the navigation safety of the ship.

[0004] At present, 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

[0014] Compared with the prior art, the present invention has the following beneficial effects: Through the arranged rudder arm main body, reciprocating lifting mechanism, heating and knocking deicing 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 deicing 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 deicing. 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 deicing effect.

[0015] 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 the use of strong external de-icing methods 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.

[0016] Through the set lubricating oil adding mechanism and lubricating oil adding active trigger mechanism, the connection and installation position of the rudder arm and the rudder stock can be automatically and intermittently filled with lubricating oil, so as to avoid the wear of the rudder stock and the rudder arm due to friction and vibration during long-term use, resulting in loose connection and displacement of the rudder arm position, which will affect 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 the single filling amount is. Because the metal parts in the corresponding connection seat of the rudder arm shrink at low temperatures, the gap becomes smaller, and more lubricating oil is needed to ensure lubrication and buffering effects and reduce component wear.

[0025] 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, percussion 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.

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. A connecting rod 76 is fixedly connected to the shaft wall of the transmission shaft 72, and a conductive block 77 corresponding to the position of the forward electric connection block 74 and the reverse electric connection block 75 is fixedly connected to the end of the connecting rod 76 away from the transmission shaft 72.

[0026] 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 ambient temperature of the rudder arm body 1 is lower than the threshold value, so that the rudder arm body 1 has an icing problem, the PLC controller controls the reciprocating lifting mechanism 2, the heating 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 section 22 set on the rotating shaft 21 and the threaded sleeve connection of the hollow lifting plate 23 enable the hollow lifting plate 23 to achieve reciprocating lifting and moving, thereby driving multiple heating mechanisms. 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 can be solved based on the set vents 9. Since the top of the rudder arm body 1 will be directly connected to the ship, the vents 9 set on the rudder arm body 1 and the reinforcing plate 8 can realize air circulation in the rudder arm body 1. The PLC controller synchronously controls the operation of the drive motor 73. The drive motor 73 drives the conductive block 77 to continuously move 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 force electromagnetic plate 310 is connected, so that the force electromagnetic plate 310 generates the same magnetism as the force-bearing 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 provide a knocking force to the rudder arm body 1, knocking off the ice layer condensed on the outer wall of the rudder arm body 1, and when the conductive block 77 moves to the connection position with the reverse electrical connection block 75, the reverse power supply circuit of the force electromagnetic plate 310 is connected, so that the force electromagnetic plate 310 generates the opposite magnetism to the force-bearing 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 knocking block 35 continuously provides a knocking force to the rudder arm body 1. By combining heating and knocking, the advantages of each can be brought into play, which is more efficient than a single de-icing method. Heating changes the physical properties of ice, and knocking directly acts on the ice layer to make it fall off. The ice layer on the surface of the rudder arm can be quickly removed, reducing the impact time of the ice layer on the navigation of the ship. The ice layer that has been formed can be removed in time, which can prevent the ice layer from continuously thickening 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 coordination method can be used to process the ice layer when it is thin, reducing the difficulty and workload of de-icing. Compared with the use of strong external de-icing methods when the ice layer is very thick, de-icing by combining heating and knocking from the inside is more gentle and uniform, which can avoid damage to the surface of the rudder arm caused by strong external de-icing, such as scratches and deformation, which is conducive to protecting the structural integrity and performance of the rudder arm. 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 air blower 41 and the driving motor 73 to work at a higher power, thereby increasing the heating intensity, the knocking intensity and the processing frequency of the hanging rudder arm body 1, and increasing the heating knocking intensity of the hanging rudder arm body 1 as a whole, thereby ensuring the quality and efficiency of the deicing work; The PLC controller and the reduction motor 63 work synchronously, and the reduction motor 63 drives the reciprocating screw 62 to rotate. The threaded sleeve connection between the reciprocating screw 62 and the trigger plate 64 allows the trigger plate 64 to move slowly in the trigger shell 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 cavity 52 in the connecting seat 10, and then injects it into the shaft hole of the connecting seat 10 through multiple oil supply grooves 53 to complete the filling of lubricating oil. This can avoid the connection between the rudder arm body 1 and the hull and the rudder blade from being worn due to friction, vibration, etc. after long-term use, resulting in loose connection, causing the position of the rudder arm body 1 to shift, affecting the heading stability of the ship, and when the ambient temperature is low, the heating air supply mechanism 4 works, and at this time the PLC controller also controls the electric heat exchange coil 55. The control valve 56 is opened, so that part of the hot air blown out by the hot air blower 41 is transported to the heat exchange coil 55 to heat the oil supply pipe 51, so as to avoid the problem that the lubricating oil has poor fluidity due to the low ambient temperature, thereby affecting the stable filling. Specifically, the lower the ambient temperature, the greater the opening degree of the electric control valve 56, so that more hot air is injected, the heating efficiency is improved, and the fluidity of the lubricating oil is ensured. At the same time, based on the ambient temperature, the PLC controller regulates the working power of the oil supply pump 54. The lower the ambient temperature, the higher the working power of the oil supply pump 54, so that in the process of filling a single lubricating oil, more lubricating oil is injected within the fixed filling time of 60s, because at low temperatures, the metal parts in the connecting seat 10 corresponding to the rudder arm will also shrink, resulting in a smaller fitting clearance. A smaller clearance requires more lubricating oil to fill, so as to ensure good lubrication and buffering effects and reduce friction and wear between parts. Therefore, increasing the amount of lubricating oil added at a single time can ensure the stability of the use of the rudder arm.
