[0001] This utility model belongs to the field of diving equipment technology, and in particular relates to an underwater drone. Background Technology

[0002] With the rapid development of drone technology, the application of drones in underwater environments, such as aquaculture biological behavior analysis, marine engineering operation inspection, and underwater infrastructure structural health monitoring, has attracted widespread attention. Underwater drones typically consist of a fuselage, a propulsion system, and operational components such as cameras mounted on the fuselage; the propulsion system enables the drone to move horizontally and vertically in the water. However, due to size limitations, these underwater drones experience significant drag in water, making ascent and descent difficult. Utility Model Content

[0003] The technical objective of this invention is to provide an underwater drone that addresses the problem of high drag on underwater drones in water.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: an underwater drone includes: a body with a sealed cabin and a camera fixed inside the sealed cabin; the head end of the body has a transparent viewing window facing the camera; the body includes a middle section and extension sections symmetrically connected to opposite sides of the middle section; the middle section and the extension sections are naturally connected, and the size of the extension sections gradually decreases from the side closer to the middle section to the side farther away from the middle section; a perforated window is also formed between the middle section and the extension sections, and a first flow guide is provided at the perforated window.

[0005] Furthermore, the extension section includes a first assembly section connected to opposite sides at the head end of the intermediate section and a second assembly section connected to opposite sides at the tail end of the intermediate section. Each first assembly section is provided with a first mounting compartment, each second assembly section is provided with a second mounting compartment, and the tail end of the intermediate section is also provided with a third mounting compartment. Each first mounting compartment, each second mounting compartment, and each third mounting compartment is equipped with a propeller. The axes of the first mounting compartment and the third mounting compartment are perpendicular to the axis of the sealed compartment, and the axis of the second mounting compartment is parallel to the axis of the sealed compartment.

[0006] Furthermore, a handle is connected between the first assembly part and the second assembly part, and the middle section, the first assembly part, the second assembly part and the handle together form a hollow window.

[0007] Furthermore, the first guide portion includes a "V"-shaped or "U"-shaped guide surface formed in the first assembly portion.

[0008] Furthermore, a second guide section is formed at the end of the first assembly section away from the second assembly section, which is gradually inclined outward and backward from the middle section.

[0009] Furthermore, a third guide portion is formed at the end of the handle that is connected to the first assembly portion, which gradually slopes outward and backward from the first assembly portion.

[0010] Furthermore, a guide fin is also connected to the outer periphery of the middle section's tail end.

[0011] Furthermore, the guide fins are also provided with anti-detachment holes for securing cables.

[0012] Furthermore, the end of the first assembly part away from the second assembly part is provided with an assembly cavity, in which an LED light is installed.

[0024] Example:

[0025] like Figure 1-5As shown, in this embodiment, the underwater drone includes: a body 1 with a sealed chamber 111 and a camera 2 fixed inside the sealed chamber 111; the head end of the body 1 has a transparent viewing window facing the camera 2; the body 1 includes a middle section 11 and extension sections 12 symmetrically connected to opposite sides of the middle section 11; the middle section 11 and the extension sections 12 are naturally connected, and the size of the extension sections 12 gradually decreases from the side closer to the middle section 11 to the side farther away from the middle section 11; a perforated window 13 is also formed between the middle section 11 and the extension sections 12, and a first guide portion 1212 is provided at the perforated window 13.

[0026] Specifically, camera 2 is fixed inside the sealed chamber 111 to achieve stable assembly. A transparent viewing window 115 is provided at the head end, through which camera 2 can acquire water images with good framing stability. The body 1 is designed with two parts: a middle section 11 and an extension section 12. The size of the extension section 12 gradually decreases from the side closer to the middle section 11 to the side farther away from the middle section 11, and the extension section 12 is symmetrically arranged on both sides of the middle section 11, which helps maintain the balance of the drone in the water. A hollow structure is designed between the middle section 11 and the extension section 12, namely a hollow window 13 and its guide surface, which reduces the weight of the body 1 and helps reduce the drag of the drone during movement, especially during ascent and descent. This can effectively reduce turbulence and improve the energy efficiency and endurance of the drone.

[0027] Furthermore, the extension section 12 includes a first assembly part 121 connected to opposite sides of the head end of the intermediate section 11 and a second assembly part 122 connected to opposite sides of the tail end of the intermediate section 11. Each first assembly part 121 is provided with a first mounting compartment 1211, and each second assembly part 122 is provided with a second mounting compartment 1221. The tail end of the intermediate section 11 is also provided with a third mounting compartment 112. Each first mounting compartment 1211, each second mounting compartment 1221, and each third mounting compartment 112 is equipped with a propeller. The axes of the first mounting compartment 1211 and the third mounting compartment 112 are perpendicular to the axis of the sealed compartment 111, and the axis of the second mounting compartment 1221 is parallel to the axis of the sealed compartment 111.

[0028] Specifically, in this embodiment, the thrusters installed in the first mounting compartment 1211 and the third mounting compartment 112 can be vertical thrusters. In some specific embodiments, the vertical thrusters can be integrated push-switch brushless vector water pumps to achieve precise rise and fall of ±30N. The hull of the mounting compartment can be designed with a "mackerel tendon" curved surface to reduce wake detachment. In this embodiment, the thrusters installed in the second mounting compartment 1221 can be horizontal thrusters. In some specific embodiments, the second mounting compartment 1221 has a closed-loop guide vector nozzle. The horizontal thrusters can be high-torque brushless direct-drive motors, and the maximum thrust of each horizontal thruster can reach 45N. This arrangement of the thruster positions in this embodiment is beneficial for achieving stable take-off and landing and navigation operations of the UAV in water.

[0029] In this embodiment, a handle 123 is connected between the first assembly part 121 and the second assembly part 122. The middle section 11, the first assembly part 121, the second assembly part 122, and the handle 123 together form a perforated window 13. The handle 123 facilitates user handling. In some specific embodiments, the handle 123 can also be designed with a gripping surface adapted to human hands, and a protective sleeve can be provided on the outer periphery of the handle 123. The protective sleeve can be a skin-friendly TPS-V protective sleeve, thereby improving the anti-slip performance of the handle 123 and making it convenient to hold with wet hands.

[0030] In this embodiment, as Figure 4 As shown, the first guide portion 1212 includes a "V"-shaped or "U"-shaped guide surface formed on the first assembly portion 121. In this embodiment, a second guide portion 1213 is also formed at the end of the first assembly portion 121 away from the second assembly portion 122, gradually sloping outward and backward from the middle section 11. In this embodiment, a third guide portion 1231 is also formed at the end of the handle portion 123 connected to the first assembly portion 121, gradually sloping outward and backward from the first assembly portion 121.

[0031] Specifically, the design of the first guide section 1212, the second guide section 1213, and the third guide section 1231 significantly reduces the resistance of the UAV in both the traveling and ascending directions, thereby improving the propulsion efficiency of the thruster. In this embodiment, the guide surfaces corresponding to the second guide section 1213 and the third guide section 1231 are structures determined by CFD (Computational Fluid Dynamics) optimization, referencing the streamlines of the octopus mantle. This facilitates efficient guidance of water flow, reduces turbulence and energy loss, and thus improves propulsion efficiency.

[0032] In this embodiment, an assembly cavity 1214 is provided at the end of the first assembly part 121 that is away from the second assembly part 122, and an LED light 3 is installed in the assembly cavity 1214. The LED light 3 can emit light close to natural light at a color temperature of 5000K to assist the camera 2 in acquiring high-definition images. In some specific embodiments, a diffuser can also be provided at the outlet of the assembly cavity 1214, so that the LED light 3 and the quartz glass diffuser work together to form a shadowless light field, which can present true colors even in night diving and murky water environments.

[0033] In this embodiment, as Figure 2 As shown, a guide fin 113 is also connected to the outer periphery of the tail end of the middle section 11. The guide fin 113 helps guide the direction of water flow and improves the balance and stability of the UAV in the horizontal direction. Furthermore, in some specific embodiments, the guide fin 113 is also provided with an anti-detachment hole 1131 for fixing the cable. The anti-detachment hole 1131 can be used to fix the cable, distribute the force, and prevent the cable from loosening.

[0034] In some specific embodiments, the sealed chamber 111 also includes a processing module and a power supply component electrically connected to the processing module. The camera 2, the processing module, and the power supply component can be encapsulated as a single unit by the encapsulation shell 4. The camera 2, each thruster, and the LED lights 3 can be electrically connected to the processing module, and the power supply component can provide power to the processing module, camera 2, each thruster, LED lights 3, and other components. In some specific embodiments, the processing module can achieve communication connection with external devices through the wiring port 114, which can be located at the tail end of the middle section 11. When wiring is required, the cable can be fixed through the anti-detachment hole 1131 to effectively prevent the cable from loosening between the cable and the drone. In some specific embodiments, a limiting ring 5 adapted to the shape of the encapsulation shell 4 can be provided. The fiber ring can be an arc-shaped metal ring, alloy ring, or plastic ring, etc. The fiber ring is sleeved on the outer periphery of the encapsulation shell 4, and both ends are connected and fixed to the body 1 by screws.

[0035] In this embodiment, the body 1 includes an upper shell and a lower shell that covers the upper shell. A clearance opening for a communicating sealed chamber 111 is formed between the head end of the upper shell and the head end of the lower shell. A flange is installed at the clearance opening, and a transparent window 115 is fixed to the flange. Specifically, the upper shell and the lower shell enclose the sealed chamber 111, and a clearance opening for a communicating sealed chamber 111 is formed between the head end of the upper shell and the head end of the lower shell. An integrated titanium alloy flange can be installed at the clearance opening, and high-throughput optical glass can be installed on the inner side of the flange to form a transparent window 115, achieving a water depth seal of 0.02MPa. The capture center axis of the camera 2 is aligned with the center of mass of the body 1, which helps to reduce attitude disturbance and ensure stable framing. In some specific embodiments, the camera 2 can refer to an edge intelligent camera, integrating intelligent functions at the camera 2 end, which can perform data processing and analysis at the network edge without transmitting the original image to a remote server for processing.

[0036] The implementation of this application enables underwater drones to possess excellent environmental adaptability and intelligence, allowing them to be applied to tasks such as aquaculture biological behavior analysis, marine engineering operation inspection, and underwater infrastructure structural health monitoring, significantly improving underwater data acquisition efficiency and intelligent decision-making capabilities. Its biomimetic body 1 design balances operational portability with environmental adaptability, providing an efficient and reliable technical solution for intelligent underwater operations.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
