Description

Technical Field

[0001] This invention belongs to the field of tools specifically applicable to underwater operations, and in particular relates to a vehicle body and an underwater unmanned vehicle. Background Technology

[0002] During maritime rescue operations, underwater unmanned vehicles are needed to detect underwater information, while rescue personnel on ships use cameras to observe the surface. In actual rescue operations, due to the large search area, multiple ships are often required, wasting manpower and resources.

[0003] To overcome the aforementioned problems, the new type of underwater unmanned vehicle is equipped with a drone. During operations, the drone searches on the water's surface while the underwater unmanned vehicle searches simultaneously underwater. This allows the search to be completed with only a few ships and multiple new underwater unmanned vehicles, saving manpower and resources.

[0004] For example, Chinese invention patent application CN112061354A, with a publication date of December 11, 2020, discloses an autonomous underwater vehicle capable of carrying and recovering drones. The underwater vehicle carries drones and can release or recover the drones when it surfaces.

[0005] However, in the aforementioned underwater vehicles, when releasing or recovering the drone, ocean waves can affect the attitude of the underwater vehicle, causing the drone to come into contact with seawater, which in turn leads to release failure and damage to the drone.

[0006] To address the aforementioned issues, Chinese invention patent CN113212713B, with an authorization announcement date of July 5, 2022, discloses an underwater vehicle supporting vertical launch. This underwater vehicle (equivalent to the vehicle body) carries a drone. Specifically, the underwater vehicle includes a storage compartment in which the drone is carried. The storage compartment has an openable hatch. An airbag is located at the front of the underwater vehicle. The hatch is located at the front of the underwater vehicle, and when the hatch is opened, it forms a launch port for the drone to pass through.

[0007] When releasing the drone, a high-pressure gas cylinder is used to inflate the airbag, causing the airbag to open. After the airbag opens, the underwater vehicle is in a vertical position due to buoyancy. Then, the propeller at the tail of the underwater vehicle starts, which moves the launch port above the water surface. Finally, the drone is launched through the launch port.

[0008] The aforementioned invention patent does not disclose whether the airbag is deflated, so there are two possibilities. First, the airbag is not deflated, and the crew uses a ship to retrieve the underwater vehicle. In this case, the underwater vehicle can no longer continue the search. Second, the airbag is deflated. In this case, it is necessary to ensure that the gas inside the airbag is completely discharged and that seawater does not enter the airbag. The aforementioned invention patent does not disclose the structure related to the above. Summary of the Invention

[0009] The purpose of this invention is to provide a vehicle body to solve the technical problem of ocean waves affecting the release of unmanned aerial vehicles.

[0010] Another objective of this invention is to provide an underwater unmanned vehicle to solve the same technical problems mentioned above.

[0011] To achieve the above objectives, the technical solution for the aircraft body provided by this invention is as follows:

[0012] An aircraft body includes a storage compartment for carrying a drone. The storage compartment has an openable hatch. The aircraft body is provided with a jet nozzle, a control unit, a high-pressure gas source storing high-pressure gas, and a jet channel connecting the high-pressure gas source and the jet nozzle. A jet valve is provided at the jet channel and / or the jet nozzle. The control unit is used to control the opening and closing of the jet valve. The jet valve has a closed state and an open state for ejecting high-pressure gas from the jet nozzle to raise the hatch above the water surface. The control unit is used to control the hatch to open when the jet valve is in the open state, and to control the hatch and the jet valve to close sequentially after the drone is released or recovered.

[0013] Furthermore, jet wings are provided on both sides of the vehicle body, with the jet nozzles located at the tail end of the jet wings.

[0014] Furthermore, the vehicle body is provided with a housing, and the jet wing has a retracted state located inside the housing to reduce the drag encountered by the vehicle body when it is underwater, and an deployed state located outside the housing. The control unit is used to control the jet valve to open when the jet wing is in the deployed state.

[0015] Furthermore, both the jet nozzles and the hatch are located at the head of the aircraft.

[0016] Furthermore, the direction of the jet nozzles is perpendicular to the axis of the vehicle body.

[0017] Furthermore, the high-pressure gas source is a high-pressure gas cylinder that is detachably installed in the storage compartment.

[0018] Furthermore, the storage compartment is equipped with a catapult system for launching drones.

[0019] Furthermore, the ejection device includes an ejection seat for launching the drone, a compression elastic element between the bottom wall of the storage compartment and the ejection seat, a telescopic mechanism inside the storage compartment, and a slot on the ejection seat for the telescopic mechanism to insert into. The telescopic mechanism has a longer state when it is inserted into the slot and a shorter state when it is not inserted into the slot when the compression elastic element is compressed. The control unit is used to control the telescopic mechanism to switch from the longer state to the shorter state so that the compression elastic element is reset and the drone is ejected.

[0020] Furthermore, the hatch is located on the outer circumferential surface of the vehicle body, and the hatch and the jet nozzle are located on opposite sides of the vehicle body.

[0021] The beneficial effects of the aircraft body of this invention are as follows: This invention is an improved invention. In this invention, the aircraft body is equipped with a jet nozzle, a jet valve, and a high-pressure air source. In use, the drone can be carried in a storage compartment and transported to the search area using the aircraft body.

[0022] During the release of the drone, the control unit opens the jet valve, allowing high-pressure gas to be ejected from the jet nozzle, providing an upward force to the vehicle body and raising the hatch above the water surface. The control unit then opens the hatch, releasing the drone from the storage compartment. Finally, the control unit sequentially closes the hatch and jet valve, allowing the vehicle to continue its underwater search operations. Throughout the entire release process, the opening formed by the open hatch remains above the water surface, preventing the drone from contacting seawater and ensuring successful release without damage from seawater.

[0023] Correspondingly, during the recovery of the drone, the jet valve is also in the open state, so as to ensure that the entrance and exit formed after the hatch is opened are always above the water surface, thus preventing the drone from coming into contact with seawater.

[0024] To achieve the above objectives, the technical solution for the underwater unmanned vehicle provided by this invention is as follows:

[0025] An underwater unmanned vehicle includes a vehicle body and a drone mounted on the vehicle body. The vehicle body includes a storage compartment for carrying the drone, the storage compartment having an openable hatch. The vehicle body is provided with a jet nozzle, a control unit, a high-pressure gas source storing high-pressure gas, and a jet channel connecting the high-pressure gas source and the jet nozzle. A jet valve is provided at the jet channel and / or the jet nozzle. The control unit is used to control the opening and closing of the jet valve. The jet valve has a closed state and an open state for ejecting high-pressure gas from the jet nozzle to raise the hatch above the water surface. The control unit is used to control the hatch to open when the jet valve is in the open state, and to control the hatch and the jet valve to close sequentially after the drone is released or recovered.

[0026] Furthermore, jet wings are provided on both sides of the vehicle body, with the jet nozzles located at the tail end of the jet wings.

[0027] Furthermore, the vehicle body is provided with a housing, and the jet wing has a retracted state located inside the housing to reduce the drag encountered by the vehicle body when it is underwater, and an deployed state located outside the housing. The control unit is used to control the jet valve to open when the jet wing is in the deployed state.

[0028] Furthermore, both the jet nozzles and the hatch are located at the head of the aircraft.

[0029] Furthermore, the direction of the jet nozzles is perpendicular to the axis of the vehicle body.

[0030] Furthermore, the high-pressure gas source is a high-pressure gas cylinder that is detachably installed in the storage compartment.

[0031] Furthermore, the storage compartment is equipped with a catapult system for launching drones.

[0032] Furthermore, the ejection device includes an ejection seat for launching the drone, a compression elastic element between the bottom wall of the storage compartment and the ejection seat, a telescopic mechanism inside the storage compartment, and a slot on the ejection seat for the telescopic mechanism to insert into. The telescopic mechanism has a longer state when it is inserted into the slot and a shorter state when it is not inserted into the slot when the compression elastic element is compressed. The control unit is used to control the telescopic mechanism to switch from the longer state to the shorter state so that the compression elastic element is reset and the drone is ejected.

[0033] Furthermore, the hatch is located on the outer circumferential surface of the vehicle body, and the hatch and the jet nozzle are located on opposite sides of the vehicle body.

In use, the drone can be carried in a storage compartment and transported to the search area by the vehicle body.

[0035] During the release of the drone, the control unit opens the jet valve, allowing high-pressure gas to be ejected from the jet nozzle, providing an upward force to the vehicle body and raising the hatch above the water surface. The control unit then opens the hatch, releasing the drone from the storage compartment. Finally, the control unit sequentially closes the hatch and jet valve, allowing the vehicle to continue its underwater search operations. Throughout the entire release process, the opening formed by the open hatch remains above the water surface, preventing the drone from contacting seawater and ensuring successful release without damage from seawater.

[0036] Correspondingly, during the recovery of the drone, the jet valve is also in the open state, so as to ensure that the entrance and exit formed after the hatch is opened are always above the water surface, thus preventing the drone from coming into contact with seawater.

[0045] To address the problems in the background art, the core inventive concept of this invention is to use high-pressure airflow to raise the hatch above the water surface, and then control the hatch to open to release or recover the drone, thereby avoiding contact between the drone and seawater.

[0046] The present invention will be further described in detail below with reference to the embodiments.

[0047] Specific embodiments of the underwater unmanned vehicle provided by this invention:

[0048] like Figures 1-6As shown, as a basic specific embodiment of the first type, the underwater unmanned vehicle includes a vehicle body 1 and a drone 7 mounted on the vehicle body 1. The vehicle body 1 includes a storage compartment 6 for carrying the drone 7. The drone 7 is mounted in the storage compartment 6, which has an openable hatch. The vehicle body 1 is provided with a jet nozzle 3, a control unit, a high-pressure gas source storing high-pressure gas, and a jet channel connecting the high-pressure gas source and the jet nozzle 3. A jet valve 5 is provided at the jet channel and / or the jet nozzle 3. The control unit is used to control the opening and closing of the jet valve 5. The jet valve 5 has a closed state and an open state for ejecting high-pressure gas from the jet nozzle 3 to make the hatch higher than the water surface 9. The control unit is used to control the hatch to open when the jet valve 5 is in the open state, and to control the hatch and the jet valve 5 to close sequentially after the drone 7 is released or recovered.

[0049] To reduce the drag experienced by the vehicle body 1 when it travels underwater, the shape of the vehicle body 1 is a rotary hydrodynamic shape. Of course, the vehicle body 1 can also be a teardrop shape or other shapes that experience less drag when traveling underwater.

[0050] In the first-type specific embodiment, the aircraft body 1 is provided with a high-pressure air chamber, and the jet valve 5 is installed at the entrance of the jet channel (or the exit of the high-pressure air chamber).

[0051] In the first-second type of specific implementation, the difference from the first-first type of specific implementation is that the jet valve 5 is installed at the jet port 3.

[0052] In the first-third type of specific embodiments, the difference from the first-first type of specific embodiments is that the jet valve 5 is installed in the middle of the jet passage.

[0053] In the first to fourth types of specific embodiments, the difference from the first to first type of specific embodiments is that the jet valve 5 is installed at both the jet port 3 and the jet passage.

[0054] In this invention, the installation position of the jet valve 5 is not limited, as long as the jet valve 5 can prevent high-pressure gas from being ejected from the jet port 3 when closed, and allow high-pressure gas to be ejected from the jet port 3 when open.

[0055] In the specific embodiments of categories 1-5, the difference from the specific embodiments of category 1-1 is as follows: Figures 1-6 As shown, the high-pressure gas source is a high-pressure gas tank 4 that is detachably installed in the storage compartment 6. By replacing the high-pressure gas tank 4, high-pressure gas can be quickly replenished to the vehicle body 1. At the same time, since the high-pressure gas tank 4 is located in the storage compartment 6, compared with the technical solution of setting up an additional chamber to accommodate the high-pressure gas tank 4, there is no need to set up an additional chamber to accommodate the high-pressure gas tank 4, and the structure is simple.

[0056] In this invention, the vehicle body 1 is equipped with a jet nozzle 3, a jet valve 5, and a high-pressure air source. During use, the drone 7 can be carried in the storage compartment 6, and the vehicle body 1 can transport the drone 7 to the search area, thereby saving energy and extending the drone 7's operating time. During search operations, personnel only need to remotely monitor the data transmitted by the vehicle body 1 and the drone 7 from the ship or shore base, effectively saving manpower and resources.

[0057] During the release of UAV 7, the control unit opens the jet valve 5, allowing high-pressure gas to be ejected from the jet nozzle 3, providing an upward force to the vehicle body 1 and raising the hatch above the water surface 9. The control unit then opens the hatch, releasing UAV 7 from the storage compartment 6. Finally, the control unit sequentially closes the hatch and jet valve 5, allowing the vehicle body 1 to continue its underwater search operations. Throughout the entire release process, the opening and exit formed by the open hatch remains above the water surface 9, preventing UAV 7 from contacting seawater and ensuring successful release without damage from seawater.

[0058] Correspondingly, during the recovery of the drone 7, the jet valve 5 is also in the open state, so as to ensure that the entrance and exit formed after the hatch is opened are always higher than the water surface 9, thus preventing the drone 7 from coming into contact with seawater.

[0059] In the first type of specific embodiment, the jet nozzle 3 is directly disposed on the vehicle body 1.

[0060] Compared to the first type of specific embodiment, in order to increase the lift on the vehicle body 1, in the second type of specific embodiment, such as... Figures 1-6 As shown, jet wings 2 are provided on both sides of the vehicle body 1, and the jet nozzle 3 is located at the tail end of the jet wing 2. At this time, after the high-pressure gas hits the water surface 9, some of the gas will return to exert an upward force on the jet wing 2, thereby increasing the lift of the vehicle body 1 and enabling the vehicle body 1 to emerge from the water better.

[0061] In the second-first specific embodiment, the jet wing 2 is fixed to the vehicle body 1. When the vehicle body 1 is underwater, the jet wing 2 experiences greater drag, which in turn causes greater drag on the vehicle body 1. As a result, the maximum speed and maximum range of the vehicle body 1 are both lower. Although this does not affect normal use, the vehicle body 1 needs to be recharged frequently.

[0062] To improve the maximum speed and range of the vehicle body 1, in the second-2 specific embodiment, unlike the second-1 specific embodiment, the vehicle body 1 is provided with a housing compartment. The jet wing 2 has a retracted state located inside the housing compartment to reduce the drag experienced by the vehicle body 1 during underwater navigation, and an deployed state located outside the housing compartment. The control unit is used to control the jet valve 5 to open when the jet wing 2 is in the deployed state. When the vehicle body 1 is underwater navigation, the jet wing 2 can be switched to the retracted state, thereby reducing the drag experienced by the vehicle body 1 and improving the maximum speed and range of the vehicle body 1.

[0063] In the specific implementation of type 2-2-1, such as Figures 1-5 As shown, the jet wing 2 is rotatably mounted on the vehicle body 1. Figure 2 As shown, when the vehicle body 1 is navigating underwater, the jet wing 2 retracts into the receiving slot, thereby reducing the drag experienced by the vehicle body 1. When releasing the UAV 7, firstly, as... Figures 3-4 As shown, jet wing 2 switches from the retracted state to the deployed state; then, as... Figure 5 As shown, jet nozzle 3 ejects air, the hatch opens after leaving the water surface 9, and drone 7 leaves storage compartment 6 through the entrance / exit; finally, refer to Figures 2-4 As shown, the jet nozzle 3 stops jetting, and the jet wing 2 switches from the deployed state to the retracted state.

[0064] Accordingly, when recovering drone 7, firstly, refer to Figures 3-4 As shown, jet wing 2 switches from the retracted state to the deployed state; then, referring to... Figure 5 As shown, jet nozzle 3 ejects air, the hatch opens after leaving the water surface 9, and drone 7 enters storage compartment 6 through the inlet / outlet; finally, refer to Figures 2-4 As shown, the jet nozzle 3 stops jetting, and the jet wing 2 switches from the deployed state to the retracted state.

[0065] In the second-2-2 type specific embodiment, the jet wing 2 is retractably mounted on the vehicle body 1.

[0066] It should be noted that the higher the maximum speed of the vehicle body 1, the shorter the time it takes for the vehicle body 1 to reach the designated search area, the earlier the search can begin after a maritime disaster, and the higher the survival rate of the victims.

[0067] To optimize the water exit effect of the vehicle body 1, the position of the jet nozzle 3 has been improved in this invention as follows:

[0068] In a preferred third embodiment, both the jet nozzle 3 and the hatch are located at the head of the vehicle body 1. In this case, the vehicle body 1 needs to be lower than the height above the water, which is beneficial for the hatch to be completely exposed above the water surface 9.

[0069] In the fourth type of specific implementation, the difference from the third type of specific implementation is that the hatch is located in the middle of the vehicle body 1, and at this time, the vehicle body 1 needs to be at a higher height above the water.

[0070] In the fourth-first embodiment, compared with the third embodiment, the gas pressure in the high-pressure gas source is higher, which enables the vehicle body 1 to rise above the water at a higher altitude, ensuring that the hatch is completely above the water.

[0071] In the specific embodiment of type 4-2, the jet nozzle 3 is simultaneously located at the head and middle of the vehicle body 1. When the vehicle body 1 emerges from the water, the jet nozzle 3 at the head ejects air first, followed by the jet nozzle 3 at the middle, thereby enabling the vehicle body 1 to emerge from the water at a higher height and ensuring that the hatch is completely submerged.

[0072] To further optimize the water exit effect of the vehicle body 1, the orientation of the jet nozzle 3 has been improved in this invention as follows:

[0073] In a preferred fifth embodiment, the jet nozzle 3 is oriented perpendicular to the axis of the vehicle body 1. At this time, when the hatch is fully submerged, the vehicle body 1 is tilted. By controlling the pressure of the high-pressure gas, the tilt angle of the vehicle body 1 can be easily controlled, thereby adjusting the release angle of the UAV 7.

[0074] In a preferred sixth embodiment, the jet nozzle 3 is oriented parallel to the axis of the vehicle body 1. In this case, similar to the invention patent with authorization publication number CN113212713B, the vehicle body 1 is in a vertical position when the hatch is fully submerged. In the sixth embodiment, the release and recovery angles of the UAV 7 cannot be adjusted, but this does not affect the release and recovery of the UAV 7.

[0075] In other specific embodiments, the orientation of the jet nozzle 3 is neither parallel nor perpendicular to the axis of the vehicle body 1. The component of the force exerted by the high-pressure gas on the vehicle body 1 is used to provide lift for the vehicle body 1. The lift experienced by the vehicle body 1 is relatively small, so it is necessary to adaptively increase the pressure of the high-pressure gas or adjust the number and position of the jet nozzles 3.

[0076] To improve the release speed of the drone 7, the release method of the drone 7 has been improved in this invention as follows:

[0077] In the seventh specific embodiment, the storage compartment 6 is equipped with a catapult device 8 for launching the drone 7. The catapult device 8 can quickly launch the drone 7, which on the one hand can shorten the release time of the drone 7, allowing the drone 7 to quickly start the search work and improve the survival rate of the victims; on the other hand, it can enable the drone 7 to quickly leave the sea surface, thereby completing the release of the drone 7 on the turbulent sea surface.

[0078] In the specific embodiment of type 7-1, the ejection device 8 includes an ejection seat 84 for launching the drone 7. A compression elastic element is provided between the bottom wall of the storage compartment 6 and the ejection seat 84. A telescopic mechanism is also provided inside the storage compartment 6. The ejection seat 84 has a slot for the telescopic mechanism to be inserted. The telescopic mechanism has a longer state when it is inserted into the slot and a shorter state when it is not inserted into the slot, provided that the compression elastic element is compressed. The control unit is used to control the telescopic mechanism to switch from the longer state to the shorter state so that the compression elastic element is reset and the drone 7 is ejected. The structure is simple. The compression elastic element is preferably a compression spring 83, and the telescopic mechanism is preferably an electric telescopic rod composed of a motor 81 and a telescopic rod 82.

[0079] When recovering the drone, firstly, the drone contacts the ejector seat 84 and compresses the elastic element. Then, the telescopic mechanism switches from a shorter state to a longer state. Finally, the drone switches to standby mode to save energy.

[0080] In the specific embodiments of type 7-2, the ejection device 8 is a conventional electromagnetic ejection device 8. For example, the drone 7 is equipped with a magnet, and the ejection device 8 is an electromagnet. When not ejecting, the electromagnet is not energized, and at this time, the magnet of the drone 7 is attracted to the electromagnet; when ejecting, the electromagnet is energized, and the magnetic poles of the electromagnet are opposite to the magnetic poles of the magnet of the drone 7, thereby ejecting the drone 7.

[0081] In the eighth specific embodiment, the aircraft body 1 does not include the catapult device 8. In this case, the UAV 7 moves out of the storage compartment 6 on its own.

[0082] It should be noted that the underwater unmanned vehicle corresponding to the Type 8 specific embodiment cannot be used in harsh environments with rough seas, and can only be used in ordinary environments with relatively calm seas. When using the underwater unmanned vehicle corresponding to the Type 7 specific embodiment, if the sea conditions are too harsh and the UAV 7 cannot safely land in the storage compartment 6, the UAV 7 can be landed on a ship, and personnel can then recover both the UAV 7 and the underwater unmanned vehicle separately.

[0083] To reduce the impact of high-pressure gas on the UAV 7, the following restrictions are placed on the location of the hatch in this invention:

[0084] In the ninth specific embodiment, the hatch is located on the outer peripheral surface of the vehicle body 1, and the hatch and the jet nozzle 3 are located on opposite sides of the vehicle body 1, thereby reducing the impact of high-pressure gas on the UAV 7.

[0085] In the 10 specific embodiments, the same as the invention patent with authorization announcement number CN113212713B is that: the hatch is located at the foremost front of the vehicle body 1, and the UAV 7 leaves the storage compartment 6 along the axial direction of the vehicle body 1.

[0086] Specific embodiments of the aircraft body 1 provided by the present invention:

[0087] Reference Figures 1-6 As shown, the only difference between the vehicle body 1 provided by this invention and the underwater unmanned vehicle is that the vehicle body 1 does not include the drone 7, while the underwater unmanned vehicle includes both the vehicle body 1 and the drone 7. The specific structure of the vehicle body 1 in this embodiment is the same as the specific structure of the vehicle body 1 in any specific embodiment of the underwater unmanned vehicle of this invention, and will not be described again here.

[0088] It should be noted that the classification of specific embodiments in this invention is based solely on specific features and does not imply that other categories do not contain this specific feature. For example, a Class 1 embodiment may have the same structure as a Class 3 or Class 5 embodiment.

[0089] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features, or organically combine different types of specific implementation methods to create supplementary solutions. Figures 1-6 The two specific embodiments given are, of course, those skilled in the art can combine them to create other specific embodiments not shown in the accompanying drawings. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
