Description

Technical Field

[0001] It relates to the field of underwater operation technology, specifically a multi-functional underwater vehicle. Background Technology

[0002] Underwater vehicles were initially used as special operations equipment in the defense and military field. However, with the development of underwater vehicle technology, underwater vehicles with improved structures have begun to appear in the public eye and are used as general underwater recreational and operational equipment.

[0003] Existing underwater vehicles still suffer from insufficient flexibility in use, partly due to the docking issue between the two hulls. The docking structure simplifies the docking process and is crucial for the ease of use of the underwater vehicle, making it a primary reason why it remains a key area for structural improvement. Secondly, existing underwater vehicles typically carry only one to two people, limiting their underwater applications. If more personnel are needed, the vehicle's structure cannot meet the requirements, impacting its endurance and preventing underwater personnel from reaching designated locations. Furthermore, existing underwater vehicles lack versatility in functionality. Their primary function is carrying personnel underwater, without offering additional features to assist with underwater activities. This limitation restricts the expansion of underwater vehicle capabilities, hindering their wider adoption and innovation. Summary of the Invention

[0004] To address the technical deficiencies in the background technology, this invention proposes a multifunctional underwater vehicle that solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

The sealing plate is disposed on the top end face of the first docking part above the hook plate and on the main body wall outside the first control box. The connecting plate extends into the space below the sealing plate of the main body. The front end of the hook plate is provided with a connecting post. The end of the connecting post away from the hook plate is fixedly connected with a hemispherical fixed end. The radius of the fixed end is larger than the radius of the connecting post. The connecting plate is provided with positioning grooves. The high part of the positioning groove is a first through hole with a circular cross-section.

The connecting arm has its rotation center at the position where it is connected to the rotating platform shaft, and its rotation center is perpendicular to the rotation center of the rotating platform. The other end of the connecting arm is connected to a limiting block with an elliptical cross-section via a rotating shaft. The limiting end is provided on the top surface of the auxiliary compartment outside the rotating platform and at the top of the first docking part. The top of the limiting end is provided with a second through hole with the same cross-sectional shape as the limiting block. A third mating hole is provided in the limiting end below the second through hole. The diameter of the third mating hole is the same as the length of the long end of the limiting block.

[0034] This invention provides a multifunctional underwater vehicle, such as... Figures 1-6 As shown, the underwater vehicle includes a main body 1, at least one auxiliary body 2, and a communication system 3. The communication system 3 is distributed in the main body 1 and the auxiliary body 2. The communication system 3 includes a first control box 31, which is detachably connected to the front end of the main body 1. The main body 1 has a docking cavity 11. One end of the auxiliary body 2 is a first docking part 21. The first docking part 21 is connected to the part of the main body 1 near the first control box 31 through a first docking structure 4. The first docking part 21 is connected to the main body 1 through a second docking structure 5. The auxiliary compartment 2 is fixed near the docking cavity 11. The other end of the auxiliary compartment 2 is the second docking part 22. The second docking part 22 is provided with a third docking structure 6. The two auxiliary compartments 2 are connected by the third docking structure 6. The internal space of the main compartment 1 in front of the docking cavity 11 is the first inner cavity 7. The internal space of the auxiliary compartment 2 behind the first docking part 21 is the second inner cavity 8. Both the first inner cavity 7 and the second inner cavity 8 are provided with battery compartments 9 on their outer sides. The power unit 10, which is electrically connected to the battery in the battery compartment 9, is provided on the outer side of the battery compartment 9.

[0035] It should be noted that: through the first docking structure 4, the first docking part 21 in the auxiliary compartment 2 is connected to the wall of the main compartment 1 in front of the docking cavity 11, thereby realizing the connection between the auxiliary compartment 2 and the main compartment 1. The docking cavity 11 can surround the outside of the first docking part 21, thereby initially positioning the auxiliary compartment 2. In order to increase the number of underwater workers that the underwater vehicle can carry, another auxiliary compartment 2 can be connected to the rear of the auxiliary compartment 2 connected to the main compartment 1. The connection between the two auxiliary compartments 2 can be realized through the second docking structure 5. The operation is simple, the connection is tight, and it can realize rapid docking and detachment underwater, thereby adjusting the number of underwater workers that can be carried.

[0036] Each sub-cabin 2 is equipped with a power unit 10 and a battery compartment 9, enabling it to continue to function normally after detaching from the main cabin 1 or the sub-cabin 2. This allows each underwater worker to detach from the underwater vehicle using the sub-cabin 2 and move to other locations to carry out underwater operations.

[0037] In addition, the communication system 3 equipped with the underwater vehicle allows underwater personnel to communicate with each other underwater and maintain contact with personnel on the ground. Moreover, the first control box 31 in the communication system 3 can be used as a docking structure between the main body 1 and the auxiliary body 2. It can also be detached from the main body 1 for use. It has multiple functions and can meet the needs of underwater personnel when performing different tasks underwater.

[0038] It needs to be further explained that, such as Figures 4-8 As shown, the second docking structure 5 includes a rotating frame 41, a docking roller 42, and a docking post 43. The end face of the first docking part 21 is provided with a first recess 44. One end of the rotating frame 41 is connected to the first recess 44 near the middle of the auxiliary compartment 2 via a rotating shaft. The other end of the rotating frame 41 is provided with a first mating hole 45. The middle part of the docking roller 42 is fitted into the first mating hole 45. Both ends of the docking roller 42 are provided with locking interfaces 46. The rear end of the bottom of the docking cavity 11 is provided with a mating groove 47. The docking post 43 is fixedly connected to the walls of the main compartment 1 on the left and right sides of the front end of the mating groove 47. The first docking part 21 is fixed to the main compartment 1 near the docking cavity 11 by the engagement of the locking interface 46 with the docking post 43 and by the rotation of the docking roller 42. The bottom end of the auxiliary compartment 2 is provided with a positioning component 48, which is fitted to the outside of the first docking part 21 that has been fixed in the docking cavity 11.

[0039] When the auxiliary compartment 2 needs to be docked with the main compartment 1, rotate the docking roller 42 to adjust the locking interface 46 to face the front of the first docking part 21 and to a horizontal position. Then, along the direction of the locking interface 46 and the docking post 43, engage the first docking part 21 into the docking cavity 11. Then, continue to rotate the docking roller 42 so that the locking interface 46 faces downward. Finally, engage the positioning component 48 into the mating groove 47 to limit the docking roller 42. This completes the docking of the auxiliary compartment 2 and the main compartment 1. The operation is simple.

[0040] Specifically, such as Figures 6-8 As shown, the positioning assembly 48 includes a positioning plate 481 and a torsion spring 482. Connecting seats 483 are provided on both the left and right sides of one end of the positioning plate 481. A first groove 484 is provided at the bottom of the sub-cabin 2, and a second mating hole 485 is provided on the outer side of the first groove 484. The connecting seat 483 is connected to the shaft of the second mating hole 485 via a rotating shaft, thus connecting to the bottom of the sub-cabin 2. The torsion spring 482 is fitted outside the rotating shaft of the connecting seat 483, and its two ends respectively abut against the wall surface of the sub-cabin 2 at the second mating hole 485. At least one protrusion 486 is provided at the end of the positioning plate 481 away from the connecting seat 483. The protrusion 486 moves into the locking interface 46 by rotating the positioning plate 481, fixing the position of the docking roller 42. A second recess 487 is provided on the surface of the positioning plate 481 near the protrusion 486.

[0041] When it is necessary to detach the auxiliary compartment 2 from the main compartment 1, the positioning plate 481, which flips up from the second recess 487, prevents the protrusion 486 from being locked in the locking interface 46, thereby allowing the docking roller 42 to rotate. By rotating the docking roller 42, the locking interface 46 is adjusted to face forward and horizontally towards the first docking part 21. With the first docking structure 4 also detached, the auxiliary compartment 2 can be detached from the main compartment 1 by pushing it backward. During the process of the auxiliary compartment 2 docking with the main compartment 1, when the docking roller 42 rotates to face the locking interface 46 towards the first docking part 21... After the main body 1 is in a horizontal position, the torsion spring 482 acts on the positioning plate 481, which causes the protrusion 486 to abut against the surface of the docking roller 42, thereby positioning the docking roller 42. This facilitates the alignment of the locking interface 46 with the docking post 43, allowing the locking interface 46 to fit more accurately onto the docking post 43. After the locking interface 46 is facing down, the protrusion 486 fits into the locking interface 46 to limit the docking roller 42, preventing the docking roller 42 from rotating without human intervention, thus ensuring a tight connection between the auxiliary compartment 2 and the main compartment 1.

[0042] It needs to be further explained that, such as Figures 9-11 As shown, the first docking structure 4 includes a hook plate 51, a connecting plate 52, and a sealing plate 53. The hook plate 51 is fixedly connected to the top end face of the first docking part 21. The connecting plate 52 is disposed at the bottom end of the first control box 31. The sealing plate 53 is disposed on the top end face of the first docking part 21 above the hook plate 51 and on the wall of the main body 1 outside the first control box 31. The connecting plate 52 extends into the space below the sealing plate 53 of the main body 1. The front end of the hook plate 51 is provided with a connecting post 54. The end of the connecting post 54 away from the hook plate 51 is fixedly connected with a hemispherical fixed end head 55. The radius of the fixed end head 55 is larger than the radius of the connecting post 54. The connecting plate 52 is provided with positioning grooves 56. The higher part of the positioning groove 56 is a first through hole 57 with a circular cross-section. The radius of the first through hole 57 is the same as the radius of the fixed end head 55. The radius of the higher part of the positioning groove 56 is the same as the radius of the connecting post 54.

[0043] When connecting the auxiliary compartment 2 to the main compartment 1, the hook plate 51 at the front end of the first docking part 21 first enters the space of the main compartment 1 below the first control box 31. After the fixed end 55 passes through the first through hole 57, the connecting column 54 is moved into the lower part of the positioning groove 56 by moving the auxiliary compartment 2. At this time, the fixed end 55 is located outside the lower part of the positioning groove 56 and cannot be moved out of the lower part of the positioning groove 56 by translation, thereby realizing the docking of the auxiliary compartment 2 to the main compartment 1. The gap between the first docking part 21 and the main compartment 1 can be sealed by two sealing plates 53 to prevent foreign objects from entering the docking position of the first docking part 21 and the main compartment 1 and affecting the connection between the two.

[0044] Specifically, such as Figures 9-11 As shown, the bottom end of the sealing plate 53 located at the first docking part 21 is provided with a sealing strip 531, and the top of the sealing plate 53 located at the main body 1 is provided with a second groove 532. After the connecting column 54 and the positioning groove 56 are engaged at the lower part, the sealing strip 531 engages with the second groove 532.

[0045] The cooperation between the sealing strip 531 and the second groove 532 not only seals the gap between the first docking part 21 and the main body 1, but also provides a certain interlocking connection between the two sealing plates 53, making the connection between the first docking part 21 and the main body 1 tighter.

[0046] It needs to be further explained that, such as Figure 2 , Figure 12 , Figure 13 and Figure 14 As shown, the third docking structure 6 includes a connecting arm 61 and a limiting end 62. A rotating platform 63 is provided on the top wall of the auxiliary compartment 2 at the second docking part 22. The top end of the rotating platform 63 is connected to one end of the connecting arm 61 via a rotating shaft. The connecting arm 61 uses its position where it is connected to the rotating platform 63 as its rotation center, and its rotation center is perpendicular to the rotation center of the rotating platform 63. The other end of the connecting arm 61 is connected to a limiting block 64 with an elliptical cross-section via a rotating shaft. The limiting end 62 is provided on the top surface of the auxiliary compartment 2 outside the rotating platform 63 and at the top end of the first docking part 21. The top end of the limiting end 62 has a second through hole 65 with the same cross-sectional shape as the limiting block 64. A third mating hole 66 is provided in the limiting end 62 below the second through hole 65. The diameter of the third mating hole 66 is the same as the length of the long end of the limiting block 64. The rotating shaft connected to the limiting block 64 is connected to a torsion handle 67.

[0047] When connecting two sub-cabins 2, the connecting arm 61 can be rotated using a combination of a rotating table 63 and a rotating connecting arm 61. The connecting arm 61, located on the front sub-cabin 2, can be rotated to the front end of the rear sub-cabin 2. Then, the connecting arm 61 can be rotated further to allow the limiting block 64 to enter the second through hole 65. Further movement of the connecting arm 61 allows the limiting block 64 to enter the third mating hole 66. Finally, the torsion handle 67 can be rotated to make the limiting block 64 perpendicular to the second through hole 65. At this point, both sides of the long end of the limiting block 64 abut against the wall surface of the limiting end head 62 below the second through hole 65. It is impossible to fix the position of the entire connecting arm 61 and thus connect the two auxiliary compartments 2 by translating it out of the third mating hole 66 along the axial direction of the second through hole 65. When it is not necessary to connect more auxiliary compartments 2, the connecting arm 61 can be rotated by combining the rotating table 63 and the rotating connecting arm 61. The connecting arm 61 is rotated to the limiting end 62 in front of the rotating table 63. By operating in the same way as when connecting the two auxiliary compartments 2, the limiting block 64 is fixed in the limiting end 62 in front of the rotating table 63, thereby fixing the connecting arm 61 and preventing the rotating end of the connecting arm 61 from rotating on its own without human operation.

[0048] It needs to be further explained that, such as Figure 1 , Figure 2 and Figure 15 As shown, the power unit 10 is connected to both sides of a C-shaped connecting frame 101. The two sides of the connecting frame 101 penetrate the wall of the main body 1 located outside the battery compartment 9 or the wall of the auxiliary body 2 located outside the battery compartment 9.

[0049] The drive direction of the power unit 10 can be adjusted by rotating the connecting frame 101, so that both the main body 1 and the auxiliary body 2 can move forward, dive or surface in the water, which is simple to operate.

[0050] It needs to be further explained that, such as Figure 16 As shown, the communication system 3 includes a second control box 32, a first controller 33, and a second controller 34. The first control box 31 is provided with a retractable antenna 313. The first control box 31 is wirelessly connected to the second control box 32 through the antenna 313. The first controller 33 is wirelessly connected to the second control box 32, and the second controller 34 is wirelessly connected to the first control box 31.

[0051] In this system, personnel on land can wirelessly transmit control signals to the second control box 32 via the first controller 33. The second control box 32 then uses a wireless communication connection with the first control box 31 to transmit the control signals, allowing the first control box 31 to control the underwater vehicle's operation by executing the received signals. This method also enables information exchange between land and underwater personnel, such as providing underwater navigation and voice communication. The second controller 34 is provided for each underwater worker. After the first control box 31 forms a wireless local area network underwater, underwater workers can connect to this network via the second controller 34 to establish wireless communication, facilitating communication between underwater workers during underwater missions and enabling communication with the land via the first control box 31. Contact is established with personnel. Furthermore, after the second controller 34, equipped with each underwater worker, connects to the wireless local area network formed by the first control box 31, it uses the processor and signal transceiver in the first control box 31 to measure the signal strength or signal arrival time, calculates the relative distance between the second controller 34 and the wireless communication access point in the first control box 31, and then uses this distance information to calculate the specific location of the second controller 34 using triangulation, thereby locating all underwater workers who have formed wireless communication within the designated area. In addition, both the first control box 31 and the second controller 34 are equipped with antennas. After surfacing to a position close to the water surface, they can extend their antennas out of the water surface to transmit radio waves, which can be captured by the Beidou satellite system, thereby achieving the location of underwater workers.

[0052] It needs to be further explained that, such as Figure 1 , Figure 2 , Figure 10 , Figure 11 and Figure 17 As shown, both the main compartment 1 below the first control box 31 and the wall of the auxiliary compartment 2 near the second docking part 22 are provided with female docking ends 12. The front end face of the first docking part 21 is provided with a male docking end 13. A sealing gasket 14 with an opening is provided at the docking point of the female docking end 12 and the male docking end 13, and the docking post 43 of the female docking end 12 is wrapped when the male docking end 13 is not connected to the female docking end 12. The female docking end 12 in the main compartment 1 is electrically connected to the battery compartment 9 in the main compartment 1. Both the female docking end 12 and the male docking end 13 in the auxiliary compartment 2 are electrically connected to the battery compartment 9 in the auxiliary compartment 2.

[0053] After the main compartment 1 and the auxiliary compartment 2 are docked, the batteries in the main compartment 1 and the auxiliary compartment 2 can be connected in series via the sub-docking end 13 to the female docking end 12. If either the main compartment 1 or the auxiliary compartment 2 experiences a power shortage, the other battery can provide power to drive the entire underwater vehicle to continue its underwater journey. Similarly, after the two auxiliary compartments 2 are docked, their batteries can also be connected in series via the sub-docking end 13 to the female docking end 12, allowing the batteries in one of the auxiliary compartments 2 to be connected in series. In the event of insufficient power, the battery of another sub-hull can provide power to enable the underwater vehicle composed of two or more sub-hulls 2 to continue underwater navigation. The sealing gasket 14 can keep the internal terminals of the sub-dating end 13 and the female docking end 12 waterproof when they are not docked. When the sub-dating end 13 and the female docking end 12 are docked, they can be flipped outward under the action of external force to connect the terminals and realize the electrical connection between the sub-dating end 13 and the female docking end 12.

[0054] It needs to be further explained that, such as Figure 3 and Figure 4 As shown in the figure, both the first inner cavity 7 and the second inner cavity 8 are equipped with water pumps 15 that are connected to the outside.

[0055] The main body 1 can actively submerge by pumping water from the outside into the first inner cavity 7 using water pump 15, and the auxiliary body 2 can actively submerge by pumping water from the outside into the second inner cavity 8 using water pump 15. When the main body 1 needs to actively rise, water pump 15 pumps water out of the first inner cavity 7 into the outside, thus enabling the main body 1 to actively rise. Similarly, water pump 15 pumps water out of the second inner cavity 8 into the outside, thus enabling the auxiliary body 2 to actively rise. Moreover, when the main body 1 or the auxiliary body 2 is in a rising or sinking state, the reverse thrust of the power unit 10 maintains the main body 1 or the auxiliary body 2 at a certain depth underwater, thereby enabling the entire underwater vehicle to hover in the water.
