Description
Technical Field
The invention belongs to the technical field of marine natural energy aircrafts, and particularly relates to a wave wing plate with functions of floating state real-time monitoring and automatic adjustment.
Background
For the research of marine science, the acquisition of marine basic hydrological data is an important link, and the key of the link is long-term real-time monitoring of marine environment. The existing monitoring method mainly comprises a large ocean observation ship, an offshore buoy, a submerged buoy and the like. However, the monitoring modes are limited, high research and development cost needs to be invested in the early stage of the observation ship, and maintenance and management needs to be carried out in the later stage; although the investment is low, the monitoring range is extremely limited, and a large amount of arrangement is needed.
The wave energy unmanned platform is observation equipment which is applied more recently, has lower manufacturing cost and wider monitoring range, and can bear long-time and large-range operation tasks. With wave-powered craft technology mature but with some problems.
Wave energy refers to kinetic energy and potential energy of waves generated by movement of fluid on the sea level driven by wind power, and belongs to mechanical energy category in a broad sense. The wave-driven vehicle is propelled by capturing wave energy in the ocean and converting the wave energy into wave-driven vehicle forward power. The ship body can generate pitching motion in waves to drive the wave wing plates to do heaving and pitching motion, and forward thrust is generated to push the ship body to move forward. A wave-driven vehicle is an offshore vehicle which is propelled by means of wave energy, and wave wing plates are generally arranged at the front and the rear of a ship body to provide thrust for the ship.
The main mode of the wave driving technology is that wave wing plates are arranged at the front and the back of a ship body and can rotate around a shaft. During the advancing process of the ship, the ship body continuously does pitching motion due to the fluctuation of the waves. Taking the wave wing plate at the bow as an example, when the bow moves upwards, the wave wing plate rotates anticlockwise around a shaft, the acting force of the fluid above the wave wing plate is inclined downwards, and the fluid has a forward component force; when the bow moves downwards, the wave wing plates rotate clockwise around the shaft, the acting force of the fluid below the wave wing plates is obliquely upward, and the forward component force drives the ship body to move forwards under the reciprocating action of waves. The working principle of the wave wing plate is shown in figure 1.
The standard posture of the wave wing plate in a still water state is a positive floating state, and the chord line of the wave wing plate is kept horizontal. Due to the fact that the machining precision is low or the surface of the wing plate is sunken due to the fact that the wave-driven vehicle has a long sailing time, the change of buoyancy possibly caused by the fact that the ship body is in a working environment for a long time, biological adhesion on the surface of the wing plate and the like are considered, and the wave wing plate shell is easy to deform. Wave pterygoid lamina shell deformation can lead to wave pterygoid lamina floating core position to change, and wave pterygoid lamina buoyancy will change when buoyancy moment is unbalanced with gravity moment and produce the angle of attack, and the wave pterygoid lamina produces the angle of attack and can lead to the increase of navigation resistance in still water.
The wave pterygoid lamina can utilize the reciprocating action of wave to provide thrust for the hull in wave environment, compares in making the wave pterygoid lamina keep just floating state in initial position, makes the wave pterygoid lamina keep specific angle of attack delta 0 in initial position, can effectively improve the propulsive effect of wave pterygoid lamina.
Application number 201610118446.3, entitled "a wave propelled catamaran that adjusts hydrofoil angle of attack by means of hidden floats" provides a method of adjusting hydrofoil angle of attack. The device connects the float arranged on the water surface with the hydrofoil, but the change of wave height along with the increase of depth under the condition of deep water waves is not considered at all, and the design can lead the influence of the attack angle problem not to be reduced or increased.
Application number 201910048763.6, entitled "an angle positioner for wave glider to adjust the angle of the wing" provides a wing angular position for wave gliders. The device can only be used to adjust the flap angle before the start of the task, and cannot be adjusted during the task. If the operation task area is large, the buoyancy moment is changed due to the change of the seawater density, and the device cannot be adjusted.

The working principle of the device is explained below by means of a specific adjustment process:
1. and (5) acquiring the floating state of the wing plate. After the wave-driven aircraft launches, the control system acquires the floating state of the wing plate by collecting current data of a monitoring circuit in the floating state monitoring system I. Metal coil 12 evenly twines on fixed axle 11, and the metal coil 12 access circuit of gleitbretter 10 centre gripping position right, and the hydrofoil floats from the flagging state gradually, floats the state monitoring slider 9 and drives gleitbretter 10 and remove left, and pterygoid lamina angle size is directly proportional with the length that the resistance wire inserts in the circuit, knows circuit current size and pterygoid lamina angle inverse ratio (for the person to set for the pterygoid lamina angle that the pterygoid lamina is in the positive superficial state 90, is 0 when being in the natural flagging state) by ohm law (I = U/R).

Taking the NACA0012 airfoil as an example, the position of the center of buoyancy of the wing after the wing is immersed in water is known to be 0.416L from the leading edge (L is the chord length of the wing), and therefore the buoyancy moment is determined. The gravity center position of the wing plate is related to the position of the floating state adjusting slide block 2, when the floating state adjusting slide block 2 moves, the gravity center position of the wave wing plate changes along the chord length direction of the wing plate, the gravity moment changes, and the wing plate rotates around a shaft due to moment unbalance.

The problem that the hydrofoil generates an attack angle in still water due to overlong processing precision and working time or biological attachment can be monitored and adjusted in real time, so that the processing difficulty is reduced on one hand, and the test time is saved on the other hand. In the task execution process, if the device needs to enter an area with large seawater density change, real-time adjustment can still be carried out without return voyage, and energy is saved.
