Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to solve the problem that a cable is wound with a propeller of an underwater robot, the invention particularly provides a sensor towing device for an unmanned self-made underwater robot, which can avoid the cable from being wound with the propeller and is convenient for replacing a floating ball or a sensor. To further illustrate the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:
example one
Referring to fig. 1 to 6, a sensor towing apparatus for an unmanned home-made underwater robot includes a torque towing shaft 1. Specifically, the torque pulling shaft 1 is a metal cylindrical shaft. The front end of the torque traction shaft element 1 is connected with a coupler 2. The front end of the torque traction shaft element 1 is connected with a propeller main shaft of the underwater robot through the shaft coupling 2. In this embodiment, the Underwater robot is an AUV device 18, that is, an Autonomous Underwater Vehicle (AUV). The coupler 2 is a known part in the mechanical field, and can be specifically selected and assembled according to the model size of a propeller main shaft of the underwater robot. In this embodiment, GIC 25X31 is preferably selected for the coupling 2.
The rear part of the torque traction shaft element 1 is provided with an axial tension bearing part 3. Specifically, the axial tension bearing part 3 is a circular plate which is fixed at the rear end of the torque traction shaft 1 and is coaxial with the torque traction shaft 1, and the diameter of the circular plate is larger than that of the torque traction shaft 1, so that a shoulder capable of transmitting traction force is formed at the transition part of the axial tension bearing part 3 and the torque traction shaft 1.
The torsion pulling shaft 1 is sleeved with a non-torsion pulling part 4 which has no torsion force transmission with the torsion pulling shaft 1. Specifically, the non-torsion stretching member 4 is also a circular plate, and a through hole having a diameter larger than that of the torsion stretching shaft 1 is formed in the center of the non-torsion stretching member 4, and the torsion stretching shaft 1 penetrates through the through hole. A spherical bearing is arranged between the non-torsion stretching component 4 and the torsion pulling shaft component 1, the inner ring of the spherical bearing is sleeved on the torsion pulling shaft component 1, and the through hole of the non-torsion stretching component 4 is sleeved on the outer ring of the spherical bearing.
The non-torsion stretching component 4 is positioned in front of the axial tension bearing part 3, and a thrust bearing 5 is sleeved on the torsion stretching shaft component 1. The shaft ring of the thrust bearing 5 is fixed on the torsion traction shaft element 1, the axial tension bearing part 3 is pressed against the end face of the shaft ring, and the non-torsion support-pull part 4 is pressed against the seat ring. The thrust bearing 5 is arranged between the axial tension bearing part 3 and the non-torsional bracing part 4. Thereby, the traction force can be transmitted between the torsion traction shaft element 1 and the non-torsion tension member 4 without transmitting the torsion force. In the technical scheme, the front is the advancing direction of the underwater robot.
The non-torsional bracing member 4 is detachably provided with a traction assembly. In this embodiment, the pulling assembly comprises a transverse pin 6. The axis of the transverse pin 6 is perpendicular to the axis of the torque-pulling shaft 1. The transverse pin 6 has two jaw members 7 mounted in scissor fashion. That is, the two claw parts 7 are provided with pin holes, and the two claw parts are arranged crosswise, and the transverse pin rod 6 penetrates through the pin holes of the two claw parts 7. The front part of the hook component 7 is provided with a hook part, and the rear part of the hook component 7 is provided with two sliding chutes with staggered projections. And a shear slide rod 8 is serially arranged in the sliding groove, and the axis of the shear slide rod 8 is parallel to the axis of the transverse pin rod 6. The shear slide bar 9 slides in the sliding groove, so that the crossing angle of the two claw parts 7 can be changed, and the opening and closing of the hook-shaped parts at the front ends of the two claw parts 7 are realized.
The shear slide bar 8 is connected with a traction annular component 9, the traction annular component 9 is positioned behind the claw component 7, and the shear slide bar 8 is conveniently driven.
The hook portion of the hook claw member 7 is hooked to the non-twist pulling member 4. That is, the hook portion of the hook claw member 7 hooks the outer edge portion of the non-twist stretching member 4 to transmit the traction force. A sleeve 10 is mounted on the transverse pin 6, the sleeve 10 extending to the side of the hook. The sleeve 10 prevents the non-twist stay member 4 from coming out from the side of the hook portion. Specifically, the sleeve 10 is a cylinder, and the side wall of the sleeve 10 is symmetrically provided with insertion holes inserted with the transverse pin rods 6. The two ends of the transverse pin 6 penetrate through the insertion holes and extend out of the sleeve 10. In this embodiment, the protruding end of the transverse insertion rod 6 is sleeved with a U-shaped frame 11, and the U-shaped frame 11 is connected with a floating ball or a sensor 13 through a cable 12. The distance between the inner wall of the sleeve 10 and the side of the hook is less than the diameter of the non-twist bracing member 4, thereby ensuring that the non-twist bracing member 4 can only be pulled out from between the finger members by axial displacement.
The outer side of the sleeve 10 is provided with a tail fin 14. The tail fin plate 14 enables the traction assembly to have a flow guiding function, and the running state of the device under water is enabled to be more stable. The tail fin 14 is a plate body welded to the sleeve 10. The tail fin plate 14 comprises an upper fin plate and a lower fin plate, and the lower fin plate is provided with a counterweight body 15. The balance weight body 15 improves the balance of the sleeve in water, and further improves the stability of the device in water. The counterweight body 15 is a metal block welded at the lower part of the lower fin plate, and the outer contour of the counterweight body is elliptic so as to reduce the self water flow resistance.
Example two
Referring to fig. 7, the present embodiment has the following distinguishing features compared with the embodiments: the diameter of the non-torsion stretching component 4 is larger than that of the axial tension bearing part 3, the specific structure of the traction assembly and the connection mode between the traction assembly and the non-torsion stretching component 4 are specifically that the traction assembly comprises a sleeve 16, the front end of the sleeve 16 is provided with a jack, the non-torsion stretching component 4 and the axial tension bearing part 3 are inserted into the jack, and the front end of the sleeve 16 is provided with a stop lever 17 through a screw.
The tail fin plate 14 is fixed on a sleeve 16, and the rear end of the sleeve 16 is connected with a floating ball or a sensor 13 through a cable 12.
