[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] This embodiment provides a sealing device for an underwater robot, such as... Figures 1-4 As shown, the underwater robot sealing device includes a propeller thruster 1. The propeller thruster 1 includes a housing 11, a battery 12 housed in the housing 11, a magnetic coil 13 fixedly installed at the opening of the housing 11, a rotating shaft 131 rotatably connected to the center of the magnetic coil 13, and a propeller hub 14 fixedly installed at the opening of the housing 11 with the propeller blades fixedly installed to the rotating shaft 131. The magnetic coil 13 is connected to the electrodes of the battery 12, and the propeller thruster 1 is equipped with a relay 15 connected to the magnetic coil 13.
[0024] The propeller 1 is externally fitted with a protective housing 2. The protective housing 2 includes a protective housing 21 with two parallel water flow holes 211 for accommodating the propeller 1, a relay sealing housing 22 fixedly connected to the protective housing 21 for accommodating the relay 15, and a conduit 23 fixedly connected between the protective housing 21 and the relay sealing housing 22 for threading the connecting wires of the propeller 1 and the relay 15.
[0025] In use, when the underwater robot needs to be started, the relay 15 is activated by an external control signal. The relay 15 closes the circuit, allowing the battery 12 to power the magnetic coil 13. After the magnetic coil 13 is energized, it generates a magnetic field, which interacts with the rotating shaft 131, driving the rotating shaft 131 to rotate. The rotation of the rotating shaft 131 drives the propeller hub 14 and the propeller blades to rotate, thereby generating forward thrust. The propeller thruster 1 is tightly wrapped by the protective shell 2. The water flow hole 211 on the protective shell 21 allows water to flow through to propel the propeller blades, while preventing the thruster from being bumped. The relay sealing shell 22 and the conduit 23 provide additional sealing protection for the relay 15 and its connecting wires, ensuring the airtightness and safety of the entire device. When it is necessary to maintain or replace the propeller thruster 1, the entire thruster assembly can be easily disassembled by simply loosening the fasteners that fix the protective shell 2, without the need for welding or complicated disassembly operations.
[0026] Specifically, the relay sealing shell 22 comprises a containing groove 221 and a groove cover 222 covering the opening end of the containing groove 221; the relay sealing shell 22 is composed of the containing groove 221 and the groove cover 222, forming a closed cavity for containing the relay 15, and the detachable structure design makes subsequent disassembly more convenient, facilitating maintenance and replacement, and reducing maintenance cost.
[0027] Further, the wire joint 151 of the relay 15 penetrates the groove cover 222 and extends to the outside, the front end of the wire joint 151 is embedded with a sealing sleeve 152 for wrapping the joint, and a locking ring 153 is screwed on the outside of the sealing sleeve 152 and in contact with the end of the sealing sleeve 152 away from the wire joint 151 for abutting against the sealing sleeve 152; the sealing sleeve 152 wraps the front end of the wire joint 151 for providing a preliminary sealing effect, and the locking ring 153 is screwed on the outside of the sealing sleeve 152 and in contact with the end of the sealing sleeve 152 away from the wire joint 151, abutting against the sealing sleeve through the locking force to further enhance the sealing effect.
[0028] It should be noted that the outer wall of the shell 11 is fixedly connected with a connecting frame 111 for fixedly mounting on the inner wall of the water flow hole 211; the connecting frame 111 enables the paddle propeller 1 to be conveniently mounted and dismounted without the need for large-scale modification of the underwater robot main body, and when maintenance or replacement of the paddle propeller is required, only dismounting and mounting through the connecting frame 111 is needed without the need for complex disassembly operation of the entire underwater robot.
[0029] Specifically, the paddle hub 14 and the end of the shell 11 close to each other respectively have a side hole 141 and a screw hole 112 corresponding to the side hole 141; the paddle hub 14 can be firmly connected to the shell 11 by penetrating the side hole 141 and screwing into the screw hole 112 through a bolt or other fastener, and the bolt connection design enables the paddle hub 14 to be conveniently dismounted and replaced without the need for complex disassembly operation of the entire paddle propeller.
[0030] Specifically, an O-shaped sealing ring is sleeved at the connection between the paddle hub 14 and the shell 11; sleeving the O-shaped sealing ring at the connection can provide additional sealing effect.
[0031] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
