Description

Technical Field

[0001] The invention relates to the technical field of marine mobile observation platforms, in particular to a single-structure wave glider based on flexible fins. Background Art

[0002] The ocean has abundant wave energy. Converting this energy into forward power for ocean mobile observation platforms can solve the energy bottleneck problem of unmanned mobile observation platforms, and thus meet the requirements of ocean observation missions for long-term and large-scale operation capabilities of observation platforms.

[0003] At present, the traditional wave glider is usually a catamaran structure, which can convert the ups and downs of waves into forward power. The working principle is: under the action of waves, the water particles have an up and down movement amplitude on the water surface, and as the water depth increases, the up and down movement amplitude of the water particles decreases. In this way, the surface mother ship can drive the underwater tractor 6 to 8 meters to do ups and downs through the flexible cable, so that the swing wing installed on the tractor and the water particles produce relative movement, thereby generating forward thrust and completing the wave energy conversion work. Therefore, the traditional catamaran wave glider has the following three shortcomings: 1. The forward speed of the catamaran wave glider is difficult to increase significantly; 2. Due to the use of the catamaran structure and the installation of a 6 to 8 meter armored cable between the surface mother ship and the underwater tractor, the deployment and recovery of the wave glider are more difficult; 3. Due to the use of the catamaran structure, the manufacturing cost of the wave glider is increased, the manufacturing process of the wave glider is increased, and manpower and material resources are wasted. Therefore, under the general trend of domestic production and mass production of wave gliders, there is an urgent need for a single-structure wave glider with low manufacturing cost and simple design.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] like Figure 1-3 As shown, an embodiment of the present invention provides a single-structure wave glider based on flexible fins, including a hull 1, a solar power generation module 2, a satellite communication module 3, a side flexible fin 4, a ventral flexible fin 5, a propeller thruster 6, a steering rudder 7, a rigid shaft 8, an elastic plate 9, and a flexible rubber 10;

[0026] The hull 1 adopts a streamlined design and has a small fluid resistance. The hull 1 has a large draft, and the waterline is basically close to the upper surface of the hull 1. The center of gravity of the hull 1 is low and the center of buoyancy is high. It has a large righting moment and good vertical stability. A rectangular groove is opened on the hull 1. The solar power generation module 2 and the satellite communication module 3 are fastened in the rectangular groove of the hull 1 by bolts. The solar power generation module 2 and the satellite communication module 3 are connected to the watertight connector through wires. The electric energy of the satellite communication module 3 is provided by the solar power generation module 2. The solar power generation module 2 is used to provide the required electric energy for the wave glider. The satellite communication module 3 is used to provide the position information of the wave glider. The propeller thruster 6 is embedded in the groove of the hull 1 and is connected to the solar power generation module 2 through a watertight connector. The steering rudder 7 is installed at the tail of the hull 1 through a rotating shaft. The side flexible fins 4 are fixed on both sides of the hull 1 through a rigid shaft 8. The side flexible fins 4 are used to obtain wave energy in the vertical direction. The rigid shaft 8 makes the side flexible fins 4 fixed relative to the hull 1. The ventral flexible fins 5 are fixed to the lower part of the hull 1 through the rigid shaft 8. The ventral flexible fins 5 are used to obtain wave energy in the horizontal direction. The rigid shaft 8 makes the ventral flexible fins 5 fixed relative to the hull 1. The side flexible fins 4 and the ventral flexible fins 5 are both embedded with rigid shafts 8. Elastic plates 9 are welded around the rigid shafts 8. The elastic plates 9 will bend greatly when subjected to force, and can return to their original state after the external force is removed. The rigid shafts 8 and the elastic plates 9 are covered with flexible rubber 10 and can swing with the elastic plates 9. Hull 1, solar power generation module 2, satellite communication module 3 , lateral flexible fins 4, ventral flexible fins 5, propeller thrusters 6, steering rudders 7, rigid shafts 8, elastic plates 9, and flexible rubbers 10 are organically combined to convert wave energy perpendicular to the sea surface and wave energy parallel to the sea surface into the driving force for the wave glider to move forward, forming the present invention. The wave glider with a single-body structure is equivalent to a rigid body floating on the water surface. Under the action of waves, the rigid body will produce six degrees of freedom in the direction of pitch, roll, deflection, forward, sideways movement, and lifting. The lateral flexible fins 4 fixedly installed on both sides of the hull 1 can convert the movement of the single-body underwater glider in the lifting, rolling and pitching directions into forward thrust. The ventral flexible fins 5 fixedly installed just below the belly of the hull 1 can convert the single-body underwater glider in the directions of roll, deflection and sideways movement into forward thrust. The movement of the wave glider is converted into forward thrust. Based on the structural characteristics of the flexible fin, compared with the catamaran wave glider, the single-body wave glider can be used without affecting various functions. A rectangular groove is opened on the hull 1, and the solar power generation module 2 and the satellite communication module 3 are fastened in the rectangular groove of the hull 1 by bolts. The solar power generation module 2 and the satellite communication module 3 are connected to the watertight connector through wires. The electric energy of the satellite communication module 3 is provided by the solar power generation module 2. The solar power generation module 2 is used to provide the required electric energy for the wave glider, and the satellite communication module 3 is used to provide the position information of the wave glider. The propeller thruster 6 is embedded in the groove of the hull 1 and connected to the solar power generation module 2 through a watertight connector. The steering tail rudder 7 is installed at the tail of the hull 1 through a rotating shaft.The side flexible fins 4 are fixed to both sides of the hull 1 through the rigid shaft 8. The side flexible fins 4 are used to obtain wave energy in the vertical direction. The rigid shaft 8 makes the side flexible fins 4 fixed relative to the hull 1. The ventral flexible fins 5 are fixed to the lower part of the hull 1 through the rigid shaft 8. The ventral flexible fins 5 are used to obtain wave energy in the horizontal direction. The rigid shaft 8 makes the ventral flexible fins 5 fixed relative to the hull 1. Rigid shafts 8 are embedded inside the side flexible fins 4 and the ventral flexible fins 5. Elastic plates 9 are welded around the rigid shafts 8. The elastic plates 9 will bend greatly when subjected to force, and can return to their original state after the external force is removed. The rigid shafts 8 and the elastic plates 9 are covered with flexible rubber 10, which can swing with the elastic plates 9.

[0027] The structure of the side flexible fin 4 is consistent with that of the ventral flexible fin 5. A battery is arranged inside the hull 1 and below the solar power generation module 2. The ventral flexible fin 5 is fixedly connected to the middle of the lower end of the hull 1 at an equal distance. The ventral flexible fin 5 is fixedly connected to the hull 1 through the rigid shaft 8. Handles are fixedly connected to both sides of the upper end of the hull 1. The satellite communication module 3 is located in the middle of the upper end of the hull 1.

[0028] The hull 1, the solar power generation module 2, the satellite communication module 3, the side flexible fins 4, the ventral flexible fins 5, the propeller thruster 6, the steering rudder 7, the rigid shaft 8, the elastic plate 9, and the flexible rubber 10 are organically combined to convert the wave energy perpendicular to the sea surface and the wave energy parallel to the sea surface into the driving force for the wave glider to move forward, thus constituting the present invention.

[0029] The monolithic wave glider is equivalent to a rigid body floating on the water surface, which will produce six degrees of freedom movement under the action of waves, namely pitch, roll, yaw, forward, sideways and heave. The side flexible fins 4 fixedly installed on both sides of the hull 1 can convert the movement of the monolithic underwater glider in the heave, roll and pitch directions into forward thrust, and the ventral flexible fins 5 fixedly installed just below the belly of the hull 1 can convert the movement of the monolithic underwater glider in the roll, yaw and sideways directions into forward thrust.

[0030] Based on the structural characteristics of the lateral flexible fins 4 and the ventral flexible fins 5, compared with a catamaran wave glider, a single-body wave glider can greatly improve its maneuverability and speed without affecting various functions.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
