Description

Technical Field

[0001] The present invention relates to the field of unmanned marine vehicles, and in particular to a self-sinking wave energy glider. Background Art

[0002] The wave glider is an unmanned vehicle that is mainly powered by wave energy. It consists of a surface hull and an underwater wave energy propeller, which are connected by a flexible cable of about 7 meters. The design of the wave glider allows it to sail on the sea for a long time, but long-term sailing and the influence of severe sea conditions may damage the wave glider.

[0003] Wave gliders generally work in the deep sea. Once damaged, they cannot return home. The cost of recovering them may far exceed the equipment itself. Wave gliders that lose control or power will become floating garbage in the ocean, which may pose a threat to ships sailing and operating at sea, and will also affect the marine environment to a certain extent. Therefore, it is best to remotely or automatically destroy damaged and unrecoverable wave gliders. Summary of the invention

[0004] The purpose of the present invention is to provide a self-sinking wave energy glider, which can trigger the self-sinking function through remote control or under specific conditions, so that the wave glider sinks to the seabed to achieve the purpose of self-destruction.

[0005] In order to achieve the above object, the basic scheme of the present invention is as follows: A self-sinking wave energy glider, comprising: A surface hull and an underwater wave energy propeller, wherein an umbilical cable is arranged between the surface hull and the underwater wave energy propeller, the surface hull is a hollow structure, and a cavity is arranged inside the surface hull; An exhaust assembly connected to the cavity for exhausting gas from the surface boat body; A water intake assembly connected to the cavity for sucking water from the outside into the surface boat body; The control unit is signal-connected to the exhaust component and the water inlet component.

[0006] Preferably, the surface boat body comprises an inner wall and an outer wall, and the cavity is formed between the inner wall and the outer wall.

[0007] Preferably, the exhaust assembly comprises an exhaust pipe and an exhaust solenoid valve, and the exhaust pipe connects the cavity and the exhaust solenoid valve.

[0008] Preferably, a buoyancy material is provided at the connection between the surface boat body and the exhaust pipe.

[0009] Preferably, the water inlet assembly includes a water pump, a water inlet solenoid valve, a through hole and a water inlet, the through hole is opened at the bottom of the surface hull, the water inlet is opened on the inner wall of the cavity, the water pump is connected to the through hole and the water inlet solenoid valve, and the water inlet solenoid valve is connected to the water inlet.

[0010] Preferably, the exhaust solenoid valve, the water inlet solenoid valve and the water pump are respectively connected to the control unit signal.

[0011] Preferably, the exhaust solenoid valve and the water inlet solenoid valve are normally closed solenoid valves.

[0012] Preferably, the self-sinking triggering conditions are remote control triggering, fault triggering, and cross-boundary triggering.

[0013] Compared with the prior art, the self-sinking wave energy glider of the present application has the following beneficial effects: The present invention, through the ingenious design of the surface hull of the wave energy glider, can realize the rapid self-sinking of the wave energy glider by simply adding components such as a water pump and a solenoid valve. At the same time, the buoyancy material inside the surface hull can realize the normal discharge of air during the self-sinking process, ensuring that the surface hull can sink reliably. The invention has multiple protection measures, and even if a certain component is damaged or malfunctions, it will not cause the wave glider to sink. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following is further described in detail through specific implementation methods: The reference numerals in the drawings of the specification include: a surface hull 1, an umbilical cable 2, an underwater wave energy propeller 3, an exhaust pipe 4, a buoyancy material 5, an exhaust solenoid valve 6, a water inlet solenoid valve 7, a water pump 8, and a control unit 9.

[0016] As attached Figure 1-4 As shown, this embodiment shows a self-sinking wave energy glider, including: a surface hull 1 and an underwater wave energy propeller 3, and an umbilical cable 2 is set between the surface hull 1 and the underwater wave energy propeller 3. The surface hull 1 is a hollow structure, and a cavity is set in the surface hull 1.

[0017] Specifically, the surface boat body 1 includes an inner wall and an outer wall, and a cavity is formed between the inner wall and the outer wall.

[0018] Under normal conditions, the internal cavity provides buoyancy for the entire wave energy glider. When it is necessary to sink, the internal cavity is filled with water and the device sinks.

[0019] The wave energy glider is internally provided with an exhaust assembly, a water intake assembly and a control unit 9. The exhaust assembly is connected to the cavity for exhausting the gas in the surface hull 1; the water intake assembly is connected to the cavity for sucking water from the outside into the surface hull 1; the control unit 9 is signal-connected to the exhaust assembly and the water intake assembly.

[0020] The exhaust assembly includes an exhaust pipe 4 and an exhaust solenoid valve 6, and the exhaust pipe 4 connects the cavity and the exhaust solenoid valve 6. The exhaust pipe 4 is close to the upper part of the surface boat 1 in the cavity. The air inlet of the exhaust pipe 4 is located at a corner of the internal cavity, and a buoyancy material 5 is provided at the connection between the surface boat 1 and the exhaust pipe 4. The air outlet of the exhaust pipe 4 passes through the inner wall of the surface boat 1 and is connected to the exhaust solenoid valve 6.

[0021] The water inlet assembly includes a water pump 8, a water inlet solenoid valve 7, a through hole and a water inlet. The surface hull 1 has a through hole at the bottom for the water pump 8 to pump water. The inner wall of the cavity has a water inlet, the water pump 8 is connected to the through hole and the water inlet solenoid valve 7, and the water inlet solenoid valve 7 is connected to the water inlet. The water outlet of the water pump 8 is connected to the water inlet of the water inlet solenoid valve 7. The upper part of the inner wall of the surface hull 1 has a water inlet, and the water outlet of the water inlet solenoid valve 7 is connected to the water inlet at the upper part of the inner wall of the surface hull 1.

[0022] At the same time, the exhaust solenoid valve 6 , the water inlet solenoid valve 7 and the water pump 8 are respectively connected to the control unit 9 by signals.

[0023] Among them, the exhaust solenoid valve 6 and the water inlet solenoid valve 7 are normally closed solenoid valves.

[0024] like Figure 4 As shown, the self-sinking triggering conditions are remote control self-sinking command triggering, fault triggering, and cross-boundary triggering.

[0025] When the wave energy glider is working normally, the control unit 9 does not output, and the exhaust solenoid valve 6, the water inlet solenoid valve 7, and the water pump 8 are all in a closed state. When the control unit 9 receives a self-sinking instruction or the self-sinking conditions are met, the control unit 9 opens the exhaust solenoid valve 6, the water inlet solenoid valve 7, and the water pump 8 in sequence. Under the action of the water pump 8, seawater enters the internal cavity of the surface hull 1 through the water inlet solenoid valve 7. The excess air in the cavity is discharged to the outside of the boat through the exhaust pipe 4 and the exhaust solenoid valve 6. The air inlet of the exhaust pipe 4 is located at a corner of the surface hull 1, and a buoyancy material 5 is designed at the corner. During the water intake process, the internal cavity of the surface hull 1 is gradually filled with water. Due to the action of the buoyancy material 5, the surface hull 1 will tilt, and the remaining air in the cavity will gather at the air inlet of the exhaust pipe 4 to ensure that the air can be discharged normally.

[0026] The control unit 9 outputs a self-sinking command when it receives it or the self-sinking conditions are met, wherein the self-sinking conditions include the occurrence of a specific fault and being outside a preset boundary range.

[0027] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
