Description
Technical Field
The invention relates to the field of ship control, in particular to a rudder device based on an intelligent temperature control surface.
Background
The traditional rudder system consists of five parts, namely a rudder blade, a steering engine, a steering device, a rotating device and the like. When steering is needed, the ship rotates the rudder blade through the steering device to generate a deflection angle, so that water flows on two sides of the rudder blade are not symmetrical any more. The side that deflects is the upstream side, and the other side is the downstream side. The flow velocity of water flow on the water-facing side is small, the flow velocity of water flow on the water-backing side is large, and under the action of the Bernoulli effect, the water flow generates pressure difference on the rudder blade, so that a rotating torque is provided for the ship, and the course of the ship is changed. In the traditional control mode, the rudder blade bears larger resistance when rotating, more energy is consumed, and a related rotating device is matched, so that a large amount of structural space of a ship is occupied. Therefore, there is a need to improve the conventional manner of manipulation.
When the object surface generates slippage, the water flow does not simply contact with the fixed wall surface with larger adhesiveness but contacts with the air bubbles with smaller obstruction, and the loss of the water flow speed flowing through the side surface is less; the water flow on the side where no slippage occurs contacts the fixed wall surface with large adhesion, and the loss of the water flow speed is large. In addition, boundary slip can also reduce the resistance to it, and the longer the length of slip formed on the surface, the greater the slip velocity of the water flow and the wall surface. (Wangkai. Solid-liquid sliding boundary research of lattice Boltzmann method [ D ] Huazhong university of science and technology, 2018.) A thermally responsive super-hydrophobic material with boundary sliding effect, which can show different wettability under the influence of temperature. When the material is not subjected to heat treatment, the material has the same physical properties as the surface of a common material; when the material is heated, the contact angle of the surface of the material is increased, and when the material is heated to a certain temperature, the contact angle reaches the maximum value and is kept unchanged, and the surface of the material shows the characteristics of super-hydrophobicity and slippage. (Jiangre, von Lin, bionic intelligent nano interface material [ M ], chemical industry Press, 2007.)
At present, steering of a ship is realized by turning a rudder blade through a steering device. When the ship deviates from a set air route in the navigation process and small-angle correction is carried out, a rudder in a cockpit needs to be operated, so that the matched rudder equipment works to rotate a rudder blade. This conventional operation is complicated and consumes a lot of energy during the rotation. In the field of small unmanned intelligent aircrafts, the traditional control mode needs more supporting devices and occupies too much structural space of the aircrafts.

The rudder blade structure builds an intelligent temperature control surface according to the actual requirements in the ship navigation process, and controls the slippage distribution of the rudder blade surface. The rudder blade structure comprises a plurality of rudder blades, the rudder blades are made of steel, and the inside of each rudder blade is designed to be a hollow structure and used for installing the temperature control device 1. The size and the like of the rudder blade are designed and manufactured according to actual requirements, the thickness of the rudder blade is reduced as much as possible under the condition of ensuring the strength, and steel with better heat conduction efficiency is adopted; the characteristics of the temperature control device 1 and the requirements in the actual working condition are comprehensively considered in the design of the rudder blade structure.
As shown in fig. 2, the thermally responsive super-hydrophobic layer exhibits a super-hydrophobic characteristic when reaching a certain temperature, thereby generating a slip phenomenon on the surface of the rudder blade. The thermal response super-hydrophobic material is coated on the outer surface of the rudder blade by a specific method so as to reduce the loss of the material under water; the outer surface of the rudder blade is coated regularly, so that materials can be effectively covered on the surface of the rudder blade during normal operation. The paint surface shows different wettability to water under the influence of temperature. When the heating treatment is not carried out, the material does not show the super-hydrophobic characteristic, and the surface of the rudder blade and the common surface have the same physical property; when heated to a certain temperature, the material shows super-hydrophobic characteristics, so that a super-hydrophobic surface is created on the rudder blade. The thermal response super-hydrophobic material shows different wettability to water under the influence of temperature, and when the environment temperature is below 10 ℃, the surface of the coated rudder blade and the common surface have the same physical properties and can not slide. Along with the rise of the temperature, the contact angle between the water flow and the surface of the rudder blade is gradually increased, when the temperature reaches a certain value, the contact angle of the surface of the rudder blade is 150-160 degrees, the super-hydrophobic characteristic is shown on the surface of the rudder blade, the slippage phenomenon is generated, and the water flow speed flowing through the surface of the side rudder blade is increased.
By utilizing the characteristics of the thermal responsiveness super-hydrophobic material, a super-hydrophobic surface is intelligently built on the rudder blade. Due to the generation of the slippage phenomenon, the velocity gradient on the boundary surface is reduced, the shearing force on the boundary surface is correspondingly reduced, the resistance applied when the water flow flows through the surface of the rudder blade is also reduced, the velocity of the fluid on the surface of the rudder blade is not 0, namely, the slippage velocity occurs, and the velocity difference is formed by the water flow flowing through the two sides of the rudder blade. According to the Bernoulli equation, under the same position height, the larger the flow speed, the smaller the pressure, the smaller the flow speed, the larger the pressure, and thus, the pressure difference is generated on the two sides of the rudder blade. The speed of water flowing through the two sides of the rudder blade is changed by regulating and controlling the slippage distribution of the two sides of the rudder blade, so that the transverse acting force required by the steering of the aircraft is generated, and the purposes of steering and turning of the aircraft are achieved.
The temperature control device 1 changes the temperature environment of the material by means of electric heating, and is installed inside the rudder blade structure so as not to increase the additional resistance of the ship. Because the steel has good thermal conductivity, the steel is heated and transferred to the surface of the rudder blade through the inner wall surface, so that the temperature environment of the material is adjusted. The rudder blade works underwater for a long time, the temperature can be reduced rapidly when water flows through the surface of the rudder blade, and the adopted heating device has the characteristics of rapid heating and sustainable heating. The heat-sensitive magnet 8 is a chemical substance, is sensitive to temperature, has magnetic property to attract the magnet 9 when the temperature is lower than a certain temperature, and can weaken the magnetism when the temperature is higher than the certain temperature, and the weakening speed is higher; the temperature setting can be realized by changing the proportion of the chemical components, and the invention sets according to the temperature characteristic of the thermal response super-hydrophobic material.
As shown in fig. 4, the rudder blade to be heated has a large area, and the shape of the inner wall surface of the rudder blade is irregular depending on the specific operating conditions. When the heating plate 6 is arranged, the plate surface 21 is designed into a shape of the plate surface 21 which is suitable for the shape of the rudder blade, a fixing buckle 5 is arranged on the heating plate 6, a fixing hole 4 is arranged on the inner wall surface of the rudder blade, and the heating plate 6 is arranged along the inner wall surface of the rudder blade; the size, shape, number and position of the heating pipes are ensured according to the actual shape of the inner wall surface of each side rudder blade. The positive electrode 17 of the heating plate 6 is connected with the U-shaped support frame 11 through the fixing groove 7; the heating tube 16 is filled with a conductive and exothermic chemical material, the tail end of the heating tube is connected with the negative electrode 18, and the heating tube 16 is fixed on the upper surface of the plate surface 21 through a fixing frame 19 and a screw 20.
The steel materials have different heat conductivities at different temperatures, and in order to heat the surface of the rudder blade to a certain temperature, the material is uniformly heated; and (3) carrying out block design, block installation and block control on the heating plate 6 according to the actual shape of each rudder blade. The size of the U-shaped support frame 11 in the temperature control device 1 should not be too large, so as to prevent the heating effect on the surface of the rudder blade from being affected. Every two heating plates 6 are symmetrically arranged on a fixing groove 7 of the temperature control device 1 to form a set of independent heating devices; when one of the heating plates fails, the normal work of other heating plates 6 cannot be influenced. In the invention, only the slip distribution on the surface of the rudder blade on one side is independently controlled to change the ship course. The temperature control devices 1 arranged on the inner wall surface of the same side are connected in series and then connected in parallel with the other side to a control panel in the cockpit.
The temperature control devices 1 are all connected with a control panel in the cockpit, a user can regulate and control the slippage distribution on the surface of the rudder blade through the control panel, and power required by the temperature control devices 1 is provided by a power generation system of a ship. The rudder blade is made of steel, the steel has good thermal conductivity, when the rudder blade on one side is heated, the temperature is prevented from being transferred to the other side, the environmental temperature on the surface of the rudder blade is changed, the side material also shows super-hydrophobic characteristics, so that the speed difference and the pressure difference of water flows on the two sides are small, the effective rudder turning force cannot be formed, and the purpose of ship steering cannot be achieved. The two sides of the axis direction of the rudder blade are respectively provided with a layer of heat insulation layer 2, and the arrangement of the heat insulation layer 2 at the joint of the rudder blade at the two sides needs attention. Each heating plate 6 outside adds one deck insulating layer 2, and this can effectual improvement heating efficiency, also can ensure that the rudder device can reach better steering effect.
In the preferred embodiment of the invention, in navigation, if the aircraft needs to turn to the right, a control panel in a cockpit is controlled, so that a binding post 14 in the temperature control device 1 connected in series with the inner wall surface of the left side of the rudder blade is connected with a power supply, the thermo-magnet 8 and the magnet 9 attract each other, and the metal plate 12, the metal sheet 10 and the U-shaped support frame 11 are closed; the lever 13 is made of metal material, and current is connected to the positive electrode 17 of the heating plates 6 at two sides through the lever 13 to form a closed circuit with the negative electrode 18, so that the chemical material in the heating tube 16 generates heat in an electric conduction mode to heat the material on the left side surface. When the temperature is increased to a certain temperature, the magnetism of the heat-sensitive magnet 8 is weakened until the magnet 9 is not attracted to the heat-sensitive magnet; the metal plate 12 in the device is light, and under the action of gravity, the metal plate 12 is disconnected from the metal sheet 10, the heating plate 6 is not heated any more, and the power supply in the device is automatically disconnected.
When the material on the left side surface shows super-hydrophobic characteristics, the contact angle of the water flow and the left side rudder blade surface reaches 150 degrees, namely a super-hydrophobic surface is built on the left side of the rudder blade. The left rudder blade can generate slippage, so that the flow velocity of water flowing through the left rudder blade is larger than that of water flowing through the right rudder blade. The Bernoulli principle shows that the pressure is small when the flow velocity on the left side is large, and the pressure is large when the flow velocity on the right side is small, so that leftward transverse acting force is generated on the rudder blade, and the aircraft turns rightward. The rudder blade works underwater, the heat dissipation effect is good, and a heat dissipation device does not need to be additionally arranged; when the temperature is reduced, the magnetism of the heat-sensitive magnet 8 is recovered and attracted with the magnet 9, the temperature control device 1 is in a closed state, and the heating plate 6 can work after the control panel is powered on; if the expected steering effect is not achieved, the left rudder blade can be continuously heated. On the surface of the rudder blade where the slip occurs, the resistance on the side surface of the rudder blade is smaller than that on the side where the slip does not occur, which contributes to the improvement of the rudder steering efficiency. After the steering is finished, the surface of the left rudder blade is restored to be the common surface, so that the water flows through the two sides of the rudder blade are in a symmetrical state, the flow rates of the two sides are the same, the transverse acting force generated during the steering disappears, and the ship is restored to be in a straight line sailing state. Similarly, when the aircraft needs to turn left, the thermally responsive material on the right side surface is heated to a certain temperature according to the above operation. The invention only relates to the independent control of the slippage distribution on the surface of the rudder blade on one side, and can also consider the slippage distribution on the two sides, rather than the full slippage state on one side, and explore which slippage distribution has larger speed difference on the two sides of the rudder blade to form larger steering force, thereby shortening the time required by steering and improving the steering efficiency.
The invention has three application modes:
firstly, when the ship needs small-angle course correction, the ship can adjust and control the surface slip distribution of the rudder blade without a steering device.
Secondly, when the ship needs to turn, the ship can be combined with a traditional rudder device, so that the rudder turning efficiency can be improved, and the time required by turning can be shortened.
Thirdly, the novel rudder for regulating and controlling the surface slippage distribution of the rudder blade does not need to occupy a large amount of structural space, can be considered to be applied to a small aircraft, is not provided with a traditional rudder steering device, and is also favorable for improving the intelligent degree of the aircraft.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
