Description

Technical Field

[0001] This invention relates to the field of hydrological monitoring, and more specifically, to a portable amphibious unmanned vessel. Background Technology

[0002] Hydrological monitoring is a core foundation for water resource management, disaster prevention and mitigation, and ecological protection. Traditional monitoring relies on manual equipment deployment, which suffers from low efficiency, high risk, and limited coverage. With the development of unmanned technology, drones and unmanned vessels have become important tools for hydrological monitoring: drones, with their advantages of maneuverability and wide field of view, can quickly complete image acquisition and meteorological parameter measurement of large areas of water; unmanned vessels can get close to the water surface and accurately collect core hydrological parameters such as water temperature, pH value, flow velocity, and water depth. Currently, more applications combine unmanned vessels and drones to achieve coordinated amphibious operation.

[0003] However, since most floating vessels and drones are currently independent structures, their current applications are simply combinations and assemblies. For floating vessels, in order to provide stable navigation support for drones, a trimaran structure is often required. However, this presents another problem: they cannot be folded and stored, occupy a large space, and are inconvenient for handling and transportation, affecting their practical use and requiring improvement.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2 As shown, a portable amphibious unmanned surface vessel (USV) is disclosed in a specific embodiment of the present invention, comprising a floating vessel 100 and two floats 200; a propulsion device 300 is installed at the rear end of the floating vessel 100; a frame 400 is installed on the top surface of the floating vessel 100, and multiple rotor power assemblies 500 for flight are installed on the frame 400; the two floats 200 are symmetrically arranged on both sides of the floating vessel 100; a retraction mechanism 600 is installed on both sides of the frame 400, and the floats 200 are installed on the retraction mechanism 600; the retraction mechanism is driven to deform, causing the floats to move inward or outward.

[0028] The aforementioned portable amphibious unmanned vessel has a foldable float structure. When folded, it reduces space occupation and facilitates handling and transportation. When unfolded, it expands the contact area and range with the water surface, providing more stable support. Furthermore, it uses a folding and unfolding mechanism as the structural component for folding and unfolding, which can achieve automatic adjustment and is convenient to use and operate.

[0029] Furthermore, the float 200 includes a first float 210, which is mounted on the retraction mechanism 600. Second floats 220 are mounted at both ends of the first float 210. The side of the second float 220 closest to the float is connected to the side wall of the first float 210 via a hinge 230. A matching latch assembly 240 is installed on the side of the second float 220 furthest from the float and the side wall of the first float 210. The outwardly unfolded second float is connected to the first float via the latch assembly, so that the end face of the second float abuts against the end face of the first float. This structure allows the float to be further folded, further reducing space occupation.

[0030] Furthermore, when the retractable mechanism is in the folded state, the distance between the two first floats is less than 2.5 times the width of the second floats. With this structural layout, the two second floats can occupy each other's space, and even if the second floats are not fixed in the overall folded state, the second floats will at least not exceed the folding range and will not swing to the end of the first floats. Furthermore, it is even better if the distance between the two first floats is twice the maximum width of the second floats, which can further reduce the swaying of the second floats.

[0031] Furthermore, another set of latches can be added to the first and second floats to fix the second float in the folded state to the first float. Combined with the above layout design, a more stable folding fit can be provided.

[0032] Furthermore, the free end of the second float 220 gradually narrows away from the first float, forming a bow-shaped structure, which can reduce water resistance and allow for smoother navigation.

[0033] Furthermore, a first support frame 710 is fixedly installed at both ends of the first float 210; a second support frame 720 is correspondingly fixedly installed on the frame 400; each retraction mechanism 600 includes a drive structure 610 and two sets of linkage transmission mechanisms 620; one end of the linkage transmission mechanism 620 is connected to the first support frame 710, and the other end is connected to the second support frame 720; the drive structure 610 is installed on the frame 400, and the drive structure 610 is connected to the two sets of linkage transmission mechanisms 620 for transmission, which drives the linkage transmission mechanism to swing around the fulcrum near the frame, so that the float moves inward or outward; the float unfolds and folds in cooperation with the drive structure and the linkage transmission mechanism, achieving an automatic adjustment effect, which is convenient for operation and use; and one float is supported by two sets of linkage transmission mechanisms, providing sufficient support force and structural strength.

[0034] Furthermore, such as Figure 1 , Figure 3 As shown, the linkage transmission mechanism 620 includes a first link 621, a second link 622, and a worm gear 623. A gear 624 is fixedly mounted at one end of the first link 621, and the first link passes radially through the center of the gear. The gear 624 is rotatably mounted on a second support frame 720, and the other end of the first link 621 is hinged to the first support frame 710. Both ends of the second link 622 are respectively hinged to the first support frame 710 and the second support frame 720. The worm gear 623 is rotatably mounted on the second support frame 720, and the worm gear 623 meshes with the gear 624 for transmission. One end of the worm gear is connected to the drive structure for transmission. The double-linkage structure effectively strengthens the support structure and its support force. Furthermore, the gear and worm gear work together to achieve effective locking, maintaining the folded or unfolded state even when the drive structure is not activated, preventing easy loosening or deformation.

[0035] Furthermore, a pair of first lugs and a pair of second lugs are fixedly provided on the first support frame; the first lugs have a first through hole, and the second lugs have a second through hole; the second lugs are located on the side of the first lugs away from the frame, and the height of the second through hole is higher than the height of the first through hole; the second support frame has a pair of third through holes and a pair of fourth through holes; the axes of the fourth through hole, the third through hole, the second through hole, and the first through hole are parallel; the gear is rotatably mounted on the third through hole via the third rotating shaft, and the other end of the first connecting rod is rotatably mounted on the first through hole via the first rotating shaft; one end of the second connecting rod is rotatably mounted on the fourth through hole via the second rotating shaft, and the other end is rotatably mounted on the third through hole via the fourth rotating shaft; the worm gear is rotatably mounted on the second support frame via a bearing; the whole structure is an assembly type, which facilitates the processing and production of each structural component and also facilitates the disassembly and replacement of parts.

[0036] Furthermore, such as Figure 3 As shown, the drive structure 610 includes a motor 613, a synchronous belt 614, a first pulley 611, two second pulleys 612, and two tension pulleys 615. The motor 613 is mounted on the frame 400 via a third support frame 730, and the first pulley 611 is mounted on the output shaft of the motor 613. The two tension pulleys 615 are mounted on the third support frame 730 and are respectively located on both sides of the first pulley 611. The second pulleys 612 are mounted on the shaft end of the worm gear 623. The first pulley 611 and the second pulleys 612 are connected by a synchronous belt 614, and the tension pulleys are adjusted to keep the synchronous belt taut. By synchronously driving two sets of linkage transmission mechanisms with one motor, the equipment cost and power consumption can be reduced. The synchronous movement of both sets of linkage transmission mechanisms can drive the float to perform smooth unfolding and folding actions. It should be noted that the synchronous belt, pulleys, and tension pulleys are all common transmission components, and their connection and combination methods are well known to those skilled in the art, and will not be described in detail.

[0037] Furthermore, there are two propulsion devices 300, which are respectively installed on both sides of the rear end of the floating vessel 100 via folding booms 310;

[0038] The propulsion device is a shaftless pump propeller structure, which completely eliminates the possibility of weeds getting tangled and improves the stability of surface operations; it can also be further folded and stored, which also prevents it from affecting the folding of the float and protects the shaftless pump propeller.

[0039] Furthermore, the rotor powertrain is a foldable structure; the rotor powertrain includes a foldable arm, a brushless motor fixed at the end of the arm, and blades assembled at the output end of the brushless motor, forming an independent integrated power output module, which is a commonly used structural module in current drones and can be purchased and used on the market, so details will not be elaborated.

[0040] Furthermore, the frame is also equipped with mounting holes for batteries and other hydrological monitoring instruments, including but not limited to the following: multi-parameter water quality meters for monitoring parameters such as pH, turbidity, and dissolved oxygen; ADCP-current meters for real-time feedback of flow velocity, water depth, and other factors; echo sounders, sonar, and other equipment for collecting underwater hydrological and topographic data. It should be noted that the instruments carried by the unmanned surface vessel mentioned above are all relatively common and can be purchased and used on the market, and will not be elaborated further.

[0041] In addition, the device is powered by both a shaftless pump and a drone, allowing it to return to base in case of underwater propulsion failure, thus improving equipment safety. Primarily used for hydrological monitoring, the device can also be used for emergency rescue in specific situations. It can precisely deploy rescue supplies such as lifebuoys, carry lighting equipment and communication relays, and conduct surface search and rescue operations with no risk of entanglement. The device can also return to base in case of malfunction, ensuring safe and efficient rescue operations.

[0042] In one preferred embodiment, the rotor powertrain of the portable amphibious unmanned surface vessel (USV) adopts a foldable structure, using a foldable UAV; the propulsion device of the floating vessel adopts a shaftless pump propulsion structure, with foldable booms installed on both sides of the rear end of the floating vessel, and the shaftless pump propulsion structure mounted on the foldable booms, which are L-shaped. Figure 2 The portable amphibious unmanned surface vessel (USV) is in its placement position. The rotor powertrain is folded, the rotors are retracted, and the folding boom connecting to the shaftless pump propulsion structure is folded upwards, detaching the shaftless pump propulsion structure from the ground to protect it. The second float of the two floats on either side of the floating vessel is folded inwards, and the retraction mechanism retracts the floats to a close position. The overall size of the equipment is minimized, reducing space occupation and facilitating handling and transportation. Figure 1 The portable amphibious unmanned surface vessel (USV) is in operational status. The rotors of the propulsion system are deployed and in normal working condition. The folding boom is folded downwards, and the shaftless pump propulsion structure is lowered to the water surface and in driving mode. The deployment and retraction mechanism is deployed, and the floats are in the deployed state. The second float in the two floats extends outwards, and the entire equipment is in operational status. Figure 1 .like Figure 2 The portable amphibious unmanned surface vessel (USV) is in its storage state. When in use, it is moved to the designated area, the deployment mechanism unfolds, and the two first floats separate to their operational positions. The two second floats are then manually deployed, causing the rotors of the propulsion system to deploy and activating. The entire USV lifts off the ground, and the folding boom folds down, lowering the shaftless pump propulsion structure to its operational position. The USV then flies to the designated working area and is in operational status. Figure 1The portable amphibious unmanned surface vessel (USV) completes hydrological monitoring or emergency rescue missions. After taking off from the work area, the folding boom folds upward, causing the shaftless pump propulsion structure to rise and retract. It then lands on a flat surface on the shore, where the rotor of the rotor powertrain folds and retracts. After a smooth landing, the two second floats are manually folded and retracted. Finally, the deployment and retraction mechanism closes, bringing the two first floats together, and the USV is in a stationary position. Figure 2 .
