Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicles, and more specifically, to an underwater vehicle. Background Art

[0002] Underwater vehicles can perform long-term autonomous tasks in complex and changeable underwater environments, such as seabed terrain mapping, marine biological monitoring, pollution detection, and underwater infrastructure inspection, etc., which greatly expands human's ability to understand and utilize the ocean. By carrying advanced sensors and communication devices, underwater vehicles can not only collect and transmit high-precision ocean data, but also conduct exploration and operations in areas that are difficult for humans to reach, such as the deep sea and polar regions.

[0003] Underwater communication of underwater vehicles usually relies on acoustic wave transmission. However, the propagation speed of acoustic waves in water is slow, the distance is limited, and it is easily affected by environmental noise, which makes it difficult to maintain real-time communication with ground stations or other devices in deep sea or long-distance tasks. Buoys can conduct radio communication with satellites or ground stations on the water surface, expanding the communication range and capabilities of large rotating bodies, thereby realizing the collaborative execution of complex tasks and data sharing, and improving the completion degree of underwater tasks.

[0004] However, in the prior art, the release of buoys is mainly to eject the buoy from the vehicle through a mechanical trigger release method, without a clear setting for the release direction of the buoy in the vehicle, which may lead to unstable direction and speed when the buoy is released. For example, when an underwater vehicle releases a load, the inside of the underwater vehicle is in a state of water ingress, and buoyancy is likely to affect the release path and final position of the buoy. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art, and provide an underwater vehicle that can achieve the safe release and stable positioning of the buoy through precise design and control.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows:

[0007] The present invention provides an underwater vehicle for an underwater vehicle, characterized by comprising:

[0010] The first driving mechanism, the first driving mechanism is connected to the buoy assembly, the first driving mechanism drives the buoy assembly to reach the hatch, the sleeve releases the cable, and the buoy body is released from the hatch.

[0011] Implementing the embodiments of the present invention will have the following beneficial effects:

Detailed implementation mode

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1 to 2 、 Figure 5 , Figure 1 In [], the first drive mechanism 3 is in the deployed state, Figure 2 In [], the first drive mechanism 3 is in the retracted state. The underwater vehicle disclosed in this embodiment includes: a carrier cabin 1, a buoy assembly 2, and a first drive mechanism 3.

[0023] The carrier cabin 1 is provided with a hatch 11. The buoy assembly 2 is arranged in the carrier cabin 1. The buoy assembly 2 includes a sleeve 21, a cable 22, and a buoy body 23. The cable 22 is connected to the buoy body 23 and is wound around the outside of the sleeve 21. The first drive mechanism 3 is connected to the buoy assembly 2. The first drive mechanism 3 drives the buoy assembly 2 to reach the hatch 11, and the sleeve 21 releases the cable 22, and the buoy body 23 is released from the hatch 11.

[0024] In this embodiment, the first drive mechanism 3 drives the buoy assembly 2 to move towards the hatch 11. The carrier cabin 1 is also provided with a hatch door (not shown in the figure) for closing the hatch 11. When the buoy assembly 2 reaches the hatch 11, the hatch door opens. The first drive mechanism 3 drives the buoy assembly 2 to move outside the hatch 11. The buoy body 23 obtains buoyancy, the cable 22 unwinds from the sleeve 21, and the buoy body 23 is released. By setting the first drive mechanism 3 to drive the buoy assembly 2 to move to the hatch 11 to release the buoy, the first drive mechanism 3 limits the movement direction of the buoy assembly 2, effectively reducing the deviation during the buoy release process, improving the positioning accuracy, and realizing the stable release of the buoy.

[0025] Furthermore, in combination with Figure 1 、 Figures 4 to 5The buoy assembly 2 also includes an installation shell 25 , and a side of the installation shell 25 close to the hatch 11 is open. The sleeve 21 , the cable 22 and the buoy body 23 are all arranged in the installation shell 25 , and the first driving mechanism 3 is connected to the installation shell 25 .

[0026] In this embodiment, the first driving mechanism 3 drives the installation housing 25 to move toward the hatch 11. When the installation housing 25 reaches the hatch 11, the hatch is opened, seawater enters the installation housing 25 through the opening, the buoy body 23 obtains buoyancy, the cable 22 is unwound from the sleeve 21, and the buoy body 23 is released. The installation housing 25 shortens the movement path of the buoy assembly 2, and the release of the buoy body 23 is more convenient. Moreover, when the underwater vehicle is flooded, the installation housing 25 blocks seawater from entering the installation housing 25, thereby preventing the buoy body 23 from obtaining buoyancy in the underwater vehicle and affecting the release path.

[0028] In this embodiment, the power source 33 is used to set the folding assembly 32 close to one end of the supporting base plate 31, and the supporting base plate 31 limits one end of the folding assembly 32. The folding assembly 32 can be extended and folded under the drive of the power source 33, thereby driving the buoy assembly 2 to move linearly to the hatch 11, reducing the deviation during the buoy release process and realizing the stable release of the buoy.

The two power sources 33 are connected to the first connecting rod 321 and the second connecting rod 322 respectively, and the power is increased while the power is balanced, which improves the stability of the folding and unfolding assembly 32.
