Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] One of the purposes of the present invention is to provide an underwater robot based on a vector eight-push layout, which has significantly improved the freedom of movement and omnidirectionality by adopting a vector eight-push layout of the thruster, and can efficiently perform various tasks in a complex and dynamic underwater environment to solve the problems existing in the prior art.

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Example 1

[0056] like Figure 1 to Figure 5As shown, this embodiment provides an underwater robot 100 based on a vector eight-push layout, including a buoyancy body 1, a propulsion mechanism 2 and an external environment monitoring mechanism 7. A control system is configured in the buoyancy body 1, and the control system can be connected to a remote terminal for communication. The remote terminal is generally set on the shore and is mainly used to collect and process a series of information collected by the underwater robot 100. The propulsion mechanism 2 includes a plurality of propellers evenly distributed on the buoyancy body 1, and any propeller is connected to the control system for communication. The propulsion mechanism 2 can drive the buoyancy body 1 to move forward, backward, move sideways, move diagonally and rotate underwater under the control of the control system, thereby realizing the multi-directional operation of the buoyancy body 1 underwater; the external environment monitoring mechanism 7 is arranged on the buoyancy body 1, and the external environment monitoring mechanism 7 is connected to the control system for communication. The external environment monitoring mechanism 7 can monitor the marine environment information and transmit the collected marine environment information to the control system.

[0057] In a feasible implementation manner, the propulsion mechanism 2 includes eight propellers, and the eight propellers are arranged in two layers, the first layer of propellers and the second layer of propellers each include four propellers, wherein: Figure 1 to Figure 5 As shown, the four thrusters of the first layer of thrusters are thruster 1 21, thruster 22, thruster 3 23 and thruster 4 24, thrusters 1 21, thrusters 22, thrusters 3 23 and thrusters 4 24 are respectively arranged at the four corners of the buoyancy body 1, and thrusters 1 21, thrusters 22, thrusters 3 23 and thrusters 4 24 of the first layer are evenly distributed on the periphery of the buoyancy body 1, thrusters 1 21, thrusters 22, thrusters 3 23 and thrusters 4 24 are arranged parallel to the up and down directions of the buoyancy body 1, and by regulating the forward and reverse rotation and / or thrust size of thrusters 1 21, thrusters 22, thrusters 3 23 and thrusters 4 24, the buoyancy body 1 can sink, ascend or maintain up and down balance in the water. Correspondingly, as Figure 3 and Figure 4As shown, the four thrusters of the second layer of thrusters are thruster 5 25, thruster 6 26, thruster 7 27 and thruster 8 28, wherein thruster 5 25 and thruster 7 27 are a group, respectively arranged at the left front and right rear of the buoyancy body 1, thruster 5 25 and thruster 7 27 face oppositely and are both arranged parallel to a diagonal line in the horizontal direction of the buoyancy body 1, wherein thruster 5 25 faces the left rear, and thruster 7 27 faces the right front; similarly, thruster 6 26 and thruster 8 28 are a group, respectively arranged at the left rear and right front of the buoyancy body 1, thruster 6 26 and thruster 8 28 face oppositely and are both arranged parallel to another diagonal line in the horizontal direction of the buoyancy body 1, wherein thruster 6 26 faces the left front, and thruster 8 28 faces the right rear. The two diagonals in the horizontal direction of the above-mentioned buoyancy body 1 intersect, and the angle between the two diagonals can be 90 degrees to 110 degrees, and the vertical state of the two diagonals is the best.

[0058] The second-layer propeller is mainly used to control the robot to accurately adjust its position in various directions, such as forward, backward, left and right lateral movement, diagonal movement, and rotation. Several feasible control methods are as follows:

[0059] (i) Forward: Turn off the two rear thrusters (thruster six 26 and thruster seven 27), and simultaneously start the two front thrusters (thruster five 25 and thruster eight 28) to run in the same direction and with the same thrust.

[0060] (ii) Backward: Turn off the two front thrusters (thruster five 25 and thruster eight 28), and simultaneously start the two rear thrusters (thruster six 26 and thruster seven 27) to run in the same direction and with the same thrust.

[0061] (III) Left lateral movement: turn off the two thrusters on the left side (thruster five 25 and thruster six 26), and simultaneously start the two thrusters on the right side (thruster seven 27 and thruster eight 28) to run in the same direction and with the same thrust.

[0062] (IV) Right lateral movement: turn off the two thrusters on the right side (thruster seven 27 and thruster eight 28), and simultaneously start the two thrusters on the left side (thruster five 25 and thruster six 26) to run in the same direction and with the same thrust.

[0063] (V) Rotational motion: Close one of the two groups and start the other group in the same direction and with the same thrust.

[0064] (vi) Diagonal movement: Close one of the two groups and start the other group with different thrust in the same direction.

[0065] It should be noted that there are many ways to achieve the robot's forward, backward, left and right lateral movement, diagonal movement and rotational movement, which are not limited to the above-mentioned ones. The forward, backward, left and right lateral movement, diagonal movement and rotational movement of the above-mentioned robot can be achieved by controlling the thrusters in different combinations.

[0066] In a feasible implementation, Figure 3 to Figure 5 As shown, the first layer of thrusters is preferably located on the upper or lower layer of the second layer of thrusters, and the thrusters in the two layers of thrusters are preferably arranged evenly and symmetrically, and the central axes of the two layers of thrusters coincide with the central axis of the buoyancy body 1, so as to improve the control accuracy of the movement direction of the buoyancy body 1 and ensure the balance and stability of the underwater robot.

[0067] In a feasible implementation, it is preferred that the first layer of propellers is located on the upper layer of the second layer of propellers. The first layer of propellers is arranged in layers above and below the second layer of propellers, which can reduce the peripheral volume of the robot and improve integration. The second layer of propellers is located below the first layer of propellers, which is conducive to improving the accuracy of direction control.

[0068] The above-mentioned first-layer thrusters and the first-layer thrusters realize the vector eight-thrust layout of the thrusters. The two-layer thrusters are used in combination, and each thruster can be independently controlled by the control system to control the steering and thrust. On the basis of ensuring the rising and sinking functions of the buoyancy body 1, the buoyancy body 1 is realized. Precise position adjustment in multiple directions such as forward, backward, left and right lateral movement, diagonal movement and rotational movement is achieved, which significantly improves the robot's freedom of movement and omnidirectionality, thereby significantly improving the robot's flexibility and movement precision in complex underwater environments.

[0069] In a feasible implementation manner, the buoyancy body 1 preferably has an independent packaging shell to achieve modularization. At the same time, the buoyancy body 1 is preferably made of high-strength alloy materials, such as titanium alloy, to ensure its stability and pressure resistance in deep-sea high-pressure environments, so as to enhance the overall strength and safety of the underwater robot and enable it to operate under extreme conditions.

[0070] In a feasible implementation, each thruster is preferably fixed to the outside of the buoyancy body 1 through a high-strength alloy frame to ensure its stability in a high-pressure environment. Each thruster is connected to the control system through a waterproof cable to ensure the reliability of signal transmission.

[0071] In this solution, by configuring an external environment monitoring mechanism 7 on the buoyancy body 1 of the underwater robot 100, the monitoring needs of the underwater robot can be met. At the same time, the propulsion mechanism 2 realizes a vector eight-push layout of multiple thrusters on the buoyancy body 1. By controlling the start-up or combined use of different thrusters, the robot can be adjusted in all directions such as forward, backward, lateral movement, diagonal movement and rotational movement, which significantly improves the robot's freedom of movement and omnidirectionality, thereby significantly improving the robot's flexibility and movement precision in complex underwater environments, and can efficiently perform various tasks in complex and dynamic underwater environments.

[0072] Example 2

[0073] like Figure 1 to Figure 7 As shown, this embodiment proposes an underwater robot 100 based on a vector eight-push layout. On the basis of Example 1, a structurally symmetrical collision buffer frame 3 is further provided on the underwater robot 100. The collision buffer frame 3 is mounted on the outer periphery of the buoyancy body 1 and is fixedly connected to the buoyancy body 1.

[0074] In a feasible implementation, the collision buffer frame 3 is preferably an icosahedral structure frame, and is made of high-strength energy-absorbing material, such as polyurethane foam material, and any tip position of the icosahedral structure frame is provided with a shock absorbing unit 4. The shock absorbing unit 4 can specifically be a silicone pad.

[0075] Collision buffer frame 3 adopts Figure 1 to Figure 7 The icosahedral structural design shown in the figure adopts high-strength energy-absorbing materials, which can effectively absorb and disperse the collision energy; the icosahedral structural frame cooperates with the shock-absorbing unit 4 to form a shock-absorbing system outside the buoyancy body 1, which can reduce the impact of external shocks on internal components and enhance the impact resistance of the underwater robot.

[0076] In a feasible implementation manner, the aforementioned icosahedral structural frame adopts an icosahedron-based intelligent roll cage.

[0077] In a feasible implementation, some or all of the shock absorbing units 4 are also provided with pressure sensors 5 and sonars 6, and both the pressure sensors 5 and sonars 6 are connected to the control system in communication. The collision buffer frame 3 with the additional pressure sensors 5 and sonars 6 has a pressure detection node, which can monitor the pressure changes inside and outside the frame in real time, provide accurate external environmental characteristics for the underwater robot, improve the reliability and life of the underwater robot in high pressure and impact environments, and ensure its safe operation under extreme conditions. Among them, the pressure sensor 5 is mainly used to sense the pressure changes in the underwater environment, especially the water pressure that increases with depth. By real-time monitoring of the environmental pressure, the robot can automatically adjust the buoyancy or posture according to the pressure feedback to ensure stable operation; the pressure sensor 5 can also be used to detect the integrity of the underwater structure or monitor potential external pressure mutations to prevent the robot from being damaged. The sonar 6 is mainly used to detect the distance of obstacles. It calculates the distance between the robot and the surrounding objects by emitting sound waves and measuring the echo time; this function of the sonar 6 is very suitable for helping the robot to perform safe navigation and obstacle avoidance operations in the underwater environment, especially under the condition of low visibility underwater, the sonar 6 is a very effective detection means.

[0078] The above-mentioned collision buffer frame 3 realizes the integration of the buffer energy absorption frame and the sensor system, and can monitor and feedback the collision situation in real time.

[0081] In a feasible implementation, Figure 1 to Figure 5 As shown, the bracket 71 preferably adopts a bilaterally symmetrical six-claw bracket, the top midpoint of which is fixed to the front center of the buoyancy body 1, and the six branches are diffusely pointed forward and extended to the outside of the collision buffer frame 3. A flow field information collector 73 is respectively set at the end of the six branches to facilitate the all-round collection of flow field information.

[0082] In a feasible implementation manner, the image collector 72 is preferably a binocular camera.

[0083] In a feasible implementation, the speed meter is preferably a Doppler speed meter. If a plurality of speed meters are arranged on the buoyancy body 1, they are preferably symmetrically distributed.

[0084] The above-mentioned external environment monitoring mechanism 7 adopts a front-end form, which can collect flow field information in real time, analyze water flow speed, direction and turbulence characteristics, assist the robot in navigation and obstacle avoidance, improve the robot's environmental perception ability and navigation accuracy, and ensure its stability and safety in complex water flow environments.

[0087] like Figure 1 to Figure 7 As shown, a plurality of information relay units 8 are provided on the collision buffer frame 3, and the plurality of information relay units 8 are evenly distributed on the collision buffer frame 3, which is beneficial to maintaining the overall balance of the robot.

In this embodiment, the battery compartments 9 are preferably arranged symmetrically on the left and right sides of the buoyancy body 1 to ensure the balance of the robot in the water.

[0090] In a feasible implementation, any battery compartment 9 has a high-strength waterproof packaging shell, such as titanium alloy, which not only realizes the modular design of the battery and can be connected to the buoyancy body 1 through a standard interface, which is convenient for rapid disassembly, replacement and maintenance from the buoyancy body 1, but also the high-strength alloy packaging shell provides the battery compartment with high strength and good sealing performance, ensuring the safety of the battery in a high-pressure underwater environment.

[0091] In a feasible implementation, an intelligent power management system is also provided, which is preferably provided in the buoyancy body 1 and is communicatively connected with the control system. The intelligent power management system is used to monitor the battery status in the battery compartment 9, which not only simplifies the management and maintenance of the battery, but also ensures that the battery compartment can provide continuous power support during the mission execution.
