[0002] Underwater robots are robots that can perform various tasks underwater. They are usually used in the fields of marine science research, seabed resource exploration, underwater archaeology, marine biology research, marine environment monitoring, etc. Underwater robots are usually equipped with thrusters, sensors, cameras, robotic arms and other equipment, and can perform various tasks underwater autonomously or remotely.

[0003] The propulsion of underwater robots usually uses propellers, underwater thrusters or underwater jets to achieve underwater propulsion and control. At the same time, underwater robots also need to be equipped with various sensors, such as sonar, cameras, underwater positioning systems, etc., in order to obtain information about the surrounding environment. These sensors can help underwater robots perform tasks such as navigation, obstacle avoidance, and target recognition.

[0004] The rapid stop of underwater robot thrusters can be achieved in the following ways:

[0005] Utilizing the reverse operation of the electric thrusters: When a quick stop is required, the movement of the underwater robot can be quickly slowed down and stopped by controlling the electric thrusters to operate in reverse.

[0006] Utilizing the attitude control system of the underwater robot: By adjusting the attitude of the underwater robot, such as changing the pitch and yaw angles of the robot, the thrust of the thrusters can be reduced, thereby achieving a quick stop.

[0007] It can be seen from the above-mentioned prior art that the propeller of the underwater robot usually needs to reverse thrust or change posture when stopping, etc., which causes high energy consumption and long stopping time.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 In this embodiment, a propulsion assembly of an underwater robot includes a driving body 1, a turbine 2 and a protective cover 3. The turbine 2 is fixedly mounted on the right output shaft of the driving body 1, and the protective cover 3 located outside the turbine 2 is fixedly mounted on the right outer side of the driving body 1.

[0031] A switch closure member is provided on the left side of the driving body 1 in this embodiment.

[0032] It should be noted that the switch closing member includes a plurality of annular hinge seats 4 which are fixed to the outside of the driving body 1 and are equidistant from each other. The outside of the hinge seats 4 is rotatably connected to a resistance-increasing housing 5 .

[0033] Among them, the resistance-increasing shell 5 is assembled and spliced ​​into a bullet shape, which is convenient for reducing water resistance during propulsion.

[0034] The driving body 1 in this embodiment is also provided with a driving switch structure for driving the switch closure member to expand and close.

[0035] It should be noted that the driving switch structure includes an electric push rod 9 fixedly installed inside the driving body 1, a movable seat 10 is fixedly installed at the push rod of the electric push rod 9, and a rotating rod 11 is rotatably connected between the movable seat 10 and the resistance-increasing housing 5.

[0036] When the push rod of the electric push rod 9 is in the maximum extended state, the resistance increasing shell 5 is perpendicular to the driving body 1. When the push rod of the electric push rod 9 is in the fully retracted state, the resistance increasing shell 5 is in the closed state, and a sealing rubber pad 8 is attached to the outer side of the resistance increasing shell 5.

[0037] The sealing rubber pad 8 is arranged on the mutually fitting surfaces of the resistance increasing housings 5 ​​when they are combined.

[0038] The switch closure member in this embodiment is provided with an elastic resistance increasing component which is expanded and contracted according to the switch closure member.

[0039] The elastic resistance increasing component comprises an installation receiving groove 6 which is arranged on the outer side of the resistance increasing housing 5 , and an elastic retractable cloth 7 is installed and fixed between two adjacent installation receiving grooves 6 .

[0040] The elastic stretch fabric 7 is a waterproof elastic fabric that can be elastically stretched and contracted.

[0041] When the resistance-increasing housing 5 is in a closed state, the elastic retractable cloth 7 is located in the installation and storage groove 6 , and when the resistance-increasing housing 5 is in an expanded state, the elastic retractable cloth 7 is fully extended.

[0042] In this embodiment, a pumping structure for pumping water out of the switch closure is provided in the driving body 1 .

[0043] It can be understood that the water pumping structure includes a micro water pump 12 installed and fixed inside the driving body 1, and the water suction port of the micro water pump 12 is connected to a water suction pipe 13 that penetrates the driving body 1 and is located in the closed space of the resistance increasing shell 5, and the other end of the water suction pipe 13 is connected to a circular tube 14, and the outer side of the circular tube 14 is connected to a number of suction heads 15, and the discharge port of the micro water pump 12 is connected to a discharge pipe 16 that penetrates and extends to the outside of the driving body 1.

[0044] The working principle of the above embodiment is:

[0045] When the underwater robot needs to be stopped urgently, the driving body 1 is stopped to drive the turbine 2 to rotate and provide power. At the same time, the electric push rod 9 is started to work to push the movable seat 10 at the push rod to move. Under the hinged rotation of the resistance-increasing shell 5 and the hinged seat 4, the resistance-increasing shell 5 can be expanded by the movement of the movable seat 10 under the connection and rotation of the rotating rod 11, the resistance-increasing shell 5 and the movable seat 10. At the same time, when the resistance-increasing shell 5 is expanded, the elastic retractable cloth 7 installed in the storage groove 6 is synchronously extended under the action of the expansion pulling force, so that each resistance-increasing shell 5 and the elastic retractable cloth 7 are expanded to form a resistance-increasing barrier, forming resistance in the water to prevent the robot from moving further, shortening the emergency stop time and reducing energy consumption.

[0046] On the contrary, in combination with the above principle, the electric push rod 9 works to pull the movable seat 10 at the push rod to move and reset, while driving the resistance-increasing shell 5 to merge, and the elastic retractable cloth 7 elastically shrinks to the installation storage groove 6 for storage. At the same time, the sealing rubber pad 8 seals the resistance-increasing shells 5 to prevent water from entering the combined space of the resistance-increasing shell 5, thereby facilitating the cooperation with the micro water pump 12. By utilizing the connection between the micro water pump 12, the water pump pipe 13, the round pipe 14, the suction head 15 and the drain pipe 16, the suction head 15 draws out the water in the combined space of the resistance-increasing shell 5 and discharges it through the drain pipe 16, so as to facilitate the pushing component to continue to advance its work.

[0047] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
