[0001] The present invention relates to an underwater vehicle, in particular to a vehicle with a catapult communication relay station. Background Art

[0002] Underwater vehicles use their own energy and various detection equipment to complete ocean detection activities such as obtaining ocean environmental parameters, monitoring the ocean environment, underwater reconnaissance and communication, underwater target detection and identification positioning, and underwater target search; they can also be used as weapon launch platforms, communication nodes, and reconnaissance platforms. In recent years, with the development of sensor technology and information technology, underwater vehicles have received more and more attention from various countries and have become a hot spot for the development of marine engineering, further promoting the development of underwater vehicles towards intelligence, integration, and refinement.

[0003] For vessels with limited size and weight, the installed hydroacoustic communication is small in size, with narrow transmission bandwidth and low transmission rate. The stable transmission distance of high-speed data at sea is short, so long-distance transmission technology has problems of low transmission rate and high transmission delay. The high mobility of ships, the complex and changeable environment of the ocean, and potential high-intensity electromagnetic interference will affect the quality of the communication link, causing frequent interruptions of the communication link or even network paralysis. Summary of the invention

A clamping device is arranged in the main cabin, and is used for clamping the positioning part of the positioning signal carrier device, and is released when the signal carrier device is ejected.

[0007] Furthermore, the clamping device includes a piezoelectric platform with a hollow interior, two piezoelectric stacks arranged in the hollow part, and two L-shaped clamping rods. The two L-shaped clamping rods are symmetrically arranged about the center of the signal carrier device. Each L-shaped clamping rod is hinged to the piezoelectric platform and the piezoelectric stack. The piezoelectric stack is extended and retracted to drive the L-shaped clamping rod to approach or move away from the signal carrier device, thereby clamping or releasing the signal carrier device.

[0008] Furthermore, the ejection device includes an electromagnetic device and a spring.

[0022] The propulsion device adopts the structure of bionic jellyfish, which has the characteristics of high flexibility and simple control, can meet the needs of complex and changing scenes, and has high adaptability to the environment. The bionic underwater vehicle takes the movement mode of jellyfish as a typical bionic model. Its configuration and control are relatively simple, the cost is low, and it has excellent stability. It can be used for detection, search, emergency rescue and other occasions in complex environments; it can also be used as a weapon launch platform, communication node, reconnaissance platform, etc. The propulsion device includes a plurality of webbed structured swing leaves 11, connecting rods 12, and electric push rods 13. The number of connecting rods 12 is N (N≥3). The end of the electric push rod 13 of the electric cylinder is evenly hinged to one end of the plurality of connecting rods 12 in a circumferential direction. The other end of the connecting rod 12 is hinged to the body of the swing leaf 11. The bolt holes of the cylinder body 10 of the electric cylinder are fastened to the connecting portion 807 at the lower end of the cabin 8. A connecting shaft 805 is provided at the lower end of the cabin 8. The upper end of the swing leaf 11 is hinged to the connecting shaft 805 at the lower end of the main cabin 8. The extension and retraction of the electric cylinder is controlled by a control unit. The extension and retraction power of the electric cylinder is transmitted to the connecting rod 12, causing the webbed structured swing leaf 11 to swing up and down, thereby driving the movement of the main cabin.

[0023] like Figure 3As shown, the signal carrier device 2 includes a fairing 201, a positioning part, an airbag 204, and a signal loading box. The positioning part includes a positioning ring 202 and a positioning part bottom plate 203. The fairing 201 is fixedly arranged at the front end of the positioning part. A vertically extending positioning column 802 is fixedly arranged in the main cabin 8. The positioning ring sleeve 202 is arranged on the positioning column 802. The positioning column limits the positioning part to move in the vertical direction in the main cabin. The inflatable part includes a first airbag 204 and an inflatable part bottom plate 210. The first airbag 204 is fixedly connected to the positioning part bottom plate 203 and the inflatable part bottom plate 210 to form a closed cavity for accommodating the signal loading box. The signal loading box includes a box cover 205 with a through hole, a thin film encapsulated with a strong oxidant, and a cover 205 with a through hole. The film layer 206, the sealing plate 207 located below the film layer, and the bottom plate 208 of the box body. The space below the sealing plate 207 and between the bottom plate 208 of the box body is a space for accommodating the signal device. The signal loading box is fastened to the bottom plate 210 of the inflation part through the bolt holes 209 at the bottom of the box. The space between the film layer and the sealing plate is filled with hydrogen peroxide. A spike is arranged below the bottom plate 203 of the positioning part. The signal carrier device 2 is equipped with an ejection device. When the signal carrier device 2 ejects upward, the bottom plate 203 of the positioning part moves downward by inertia. The spike passes through the through hole of the box cover 205 and pierces the film layer 206. The strong oxidant contacts the hydrogen peroxide to generate oxygen. The oxygen overflows from the through hole of the box cover and fills the first airbag 204. The first airbag is inflated to increase its volume. The first airbag 204 needs to have strong ductility.

[0024] like Figure 4 As shown, the ejection device includes an electromagnetic device 6 and a spring 7. The electromagnetic device 6 includes a circular track and two electromagnetic sliders arranged in the circular track. The inner diameter of the circular track is larger than the outer diameter of the spring 7, allowing the spring 7 to extend out of the circular track. The circular track is symmetrically provided with two grooves, the grooves are radially along the circular track, an electromagnet 602 is arranged in the groove, the electromagnetic slider is arranged outside the groove, and compresses the spring 7. When the electromagnet is energized, the electromagnetic slider is adsorbed, and the electromagnetic slider moves along the groove, and the spring 7 restores the shape to eject the signal carrier device.

[0025] like Figure 5 As shown, the clamping device includes a piezoelectric platform 401 with an internal hollow part, two piezoelectric stacks 402 arranged in the hollow part and two L-shaped clamping rods. The two L-shaped clamping rods are symmetrically arranged about the center of the signal carrier device 2. Each L-shaped clamping rod is hinged to the piezoelectric platform and the piezoelectric stack 402. The piezoelectric stack 402 is extended and retracted to drive the L-shaped clamping rod to approach or move away from the signal carrier device 2, thereby clamping or loosening the signal carrier device 2. The clamping device is fixed in the main cabin by fastening it to the upper boss 803 of the cabin 8 through the bolt hole 403 with bolts.

[0026] like Figure 6 and Figure 7As shown, a central platform 810 for accommodating the spring 7 is arranged at the bottom of the main cabin 8, a circular track is fixedly arranged on the top of the central platform 810, an upper boss 803 and a lower boss 804 are arranged on the side wall of the main cabin, and an air hole 808 for the inflation pipe to pass through is arranged at the bottom of the main cabin. The attitude adjustment device 5 includes 3 groups of adjustment motors and wheels, the output shaft of the adjustment motor is along the radial direction of the main cabin, the wheel is connected to the output shaft of the adjustment motor, the wheel rotates with the output shaft of the adjustment motor as the central axis, and the adjustment motor is fastened to the lower boss 804 inside the cabin. When the wheel rotates, it has angular momentum around the vertical axis. Due to the existence of angular momentum conservation, the entire system needs to rotate in the opposite direction to the spin to maintain balance. After that, three reaction vector wheels are respectively installed at different positions on the inner wall of the aircraft. The attitude of the entire system is changed by adjusting the rotation speed of the vector wheels respectively. Each power switch controls the rotation speed of a motor, and the overall moving direction of the aircraft is controlled by different rotation speed differences.

[0027] like Figure 8 As shown, the emergency escape device 9 includes a plurality of second airbags 903, whose mounting holes 901 are fastened to the holes 809 at the bottom of the cabin 8 by bolts, and the second airbags 903 are inflated by the inflation tube through the air hole 808 and the inflation hole 902. The second airbags are inflated to increase the volume and are located outside the main cabin. The bottom of the aircraft body is equipped with six compressed airbags to achieve buoyancy and floating on the sea. In case of emergency buoyancy, the six airbags are inflated to generate large buoyancy; after being inflated, they can float on the sea, achieving the purpose of energy saving.

[0028] The control unit includes a power supply, a controller, an electric cylinder, and an air pump. The power supply has multiple power switches, which respectively control the opening and closing of the hatch, the extension and retraction speed of the electric cylinder, and the motor speed of the three attitude adjustment devices to change the attitude of the aircraft. The aircraft will tilt to the side with a faster speed. The on and off status of the power supply of the piezoelectric clamping mechanism 4 and the ejection device is controlled. When disconnected, the piezoelectric clamping mechanism 4 is in a clamped state, the electromagnetic device 6 is in a closed state, and the spring 7 is in a tightened state. When the power is energized, the piezoelectric 402 obtains that the piezoelectric clamping mechanism 4 is in a loosened state, and the electromagnet 602 attached to the electromagnetic device is energized to move the sliders 601 at both ends to the ends of the groove, so that the spring is reset. The power spring resets, thereby driving the loader equipped with the communication relay station to be ejected into the air along the positioning rod.

[0029] The operation principle of the above-mentioned aircraft is as follows: by learning from the movement of jellyfish, the entire propulsion device drives the push rod through the electric cylinder to drive the paddle-shaped structure of the swing leaf 11 to swing up and down to realize the movement of the aircraft underwater; three reaction vector wheels are installed at different positions on the inner wall of the aircraft, and the attitude of the entire system is changed by adjusting the rotation speed of the vector wheels. In case of emergency, the airbags at the corresponding positions at the bottom are quickly filled with gas, and the attitude of the aircraft is adjusted in time to avoid danger; when reaching the designated position, all airbags are filled with gas, so that the aircraft floats to the surface, thereby completing the preparation work for the launch of the signal relay station; usually, the signal loader is placed on the ejection device, and it is fixed and stabilized by the piezoelectric clamping mechanism and the guide rod. When the hatch is opened for launch, the controller sends a signal to start the ejection program, causing the electromagnet device to shift and then trigger the ejection device, so that the projectile equipped with the signal device is ejected into the air. At the same time, due to inertia, the upper and lower plate layers are brought close to each other and the film layer is pierced, allowing the catalyst on it to enter the hydrogen peroxide and react violently to generate a large amount of oxygen, causing the surrounding air bags to expand rapidly to fill the entire space. After being launched to a certain height, it slowly descends in the form of a parachute and finally floats on the sea.
