DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0026] In the first aspect, the utility model embodiment provides a bottom traveling device, please refer to Figures 1-3 , including frame 10, slide plate 210 mechanism 20 and track 320 mechanism 30;Track 320 mechanism 30 includes driving piece 310 and track 320 that sets on driving piece 310, and driving piece is arranged on frame 10, and slide plate 210 mechanism 20 includes slide plate 210 and lifting piece;Lifting piece is connected frame 10 in one end, and is connected slide plate 210 in other end, and lifting piece is used to extend and retract to make slide plate 210 touch ground and track 320.
[0027] The water bottom traveling device of the embodiment can be used in the following conditions: when the water bottom is hard, or when the silt layer of the water bottom is shallow, the driving member 310 in the track 320 mechanism 30 drives the track 320 to move, so as to make the underwater robot walk. The underwater robot can adapt to various rugged water bottoms. When it is found that the silt is too deep, the lifting member is started, the slide plate 210 contacts the silt, and the track 320 is elevated. Since the slide plate 210 has a larger contact surface relative to the track 320, the underwater robot will not be in the silt.
[0028] In an embodiment, the driving member includes a support member 3110 and a driving unit 3120, the driving unit 3120 is arranged on the frame 10 and partially arranged in the support member 3110, and the support member 3110 is used for supporting the track 320.
[0029] In the embodiment, the support member 3110 is mainly used for tensioning the track 320, and the driving unit 3120 is mainly used for driving the track 320. The driving unit 3120 generally includes a driving wheel and a transmission shaft, the transmission shaft is connected with the driving wheel and the frame 10, and the driving wheel is generally arranged on the support member 3110.

[0031] In the embodiment, the track 320 has a certain deformation ability. The inclined arrangement of the end portions 3110b on both ends of the main body 3110a can ensure that part of the track 320 falls between the two end portions 3110b in a relaxed state, so as to avoid the track 320 from falling due to excessive relaxation.
[0032] In an embodiment, the part of the end portion 3110b away from the main body 3110a is in an arc shape.
[0033] The arc-shaped part of the end portion 3110b away from the main body 3110a can better fit the track 320, so as to avoid mutual abrasion between the track 320 and the end portion 3110b.
[0034] In an embodiment, the driving unit 3120 is provided with three driving units, and the three driving units are equally spaced on the support member 3110.
[0035] Since the track 320 is relatively heavy and has a large friction with the sea bottom, a larger driving force is required. The provision of three driving units on the support member 3110 can ensure that the track 320 is evenly stressed and has sufficient power.
[0036] In an embodiment, the slide plate 210 mechanism 20 further includes an inclined plate 220, and the inclined plate 220 is arranged on one end of the slide plate 210 in an upwardly inclined manner.
[0037] The inclined plate 220 can play a guiding role to avoid the sliding plate 210 from being inserted into the silt, and the principle is equivalent to a ski.
[0038] In the second aspect, the utility model provides a kind of underwater robot, including propeller 40 and the water bottom travelling device of any one of first aspect, propeller 40 is connected on frame 10 and is used to push underwater robot swim.
[0039] Using underwater robot of the embodiment, in the case where sliding plate 210 touches ground, propeller 40 is started, and propeller 40 will make underwater robot have a advancing force.The friction of sliding plate 210 with silt is very low, so propeller 40 can push sliding plate 210 to slide relative to silt.Using underwater robot in the utility model, the purpose that water robot can travel in soft silt can be realized.
[0040] In an embodiment, further comprising manipulator 50, manipulator 50 is arranged on frame 10.
[0041] The setting of manipulator 50 is generally used to cut damaged cable, or reconnect to repair broken cable.Alternatively, manipulator 50 can be used to complete some underwater maintenance, installation and other operations.
[0042] In an embodiment, further comprising hydraulic system 60, hydraulic system 60 is arranged in frame 10, and is used to drive water bottom travelling device, propeller 40 and manipulator 50.
[0043] In an embodiment, please refer to Figure 1 And Figure 4 Hydraulic system (not shown in figure) includes motor 610, oil tank 620, pump 630, servo valve 640, output end 650 and oil pipe 660, oil pipe 660 is in series with oil tank 620, pump 630, servo valve 640 and output end 650 in sequence, motor 610 is used to drive pump 630, pump 630 is used to drive liquid to flow in oil pipe 660, servo valve 640 is used to control the flow of liquid and control liquid flow direction between servo valve 640 and output end 650, output end 650 is used to drive water bottom travelling device, propeller 40 and manipulator 50.
[0044] In the embodiment, motor 610 drives pump 630, and pump 630 makes oil in oil pipe 660 have certain oil pressure.By electromagnetic valve control liquid flow and liquid flow direction in oil pipe 660, so that output end 650 is driven.
[0045] Generally speaking, the form of the output end 650 is mostly a plunger motor. The plunger motor is a type of hydraulic motor, which works on the principle that the working medium (such as hydraulic oil) acts on the end face of the piston or plunger to make the piston or plunger do linear reciprocating motion, and then the reciprocating motion of the piston or plunger is converted into the circular motion of the output shaft through a motion conversion mechanism (such as a swash plate, a cam, a crank, etc.). The conversion mechanism of the plunger motor enables it to convert hydraulic energy into mechanical energy, thereby driving various equipment.
[0046] It should be noted that the hydraulic system also includes an oil pressure control assembly 670, which can be used to distribute the liquid pressure on a pipeline, so that one pump machine 630 can drive multiple output ends 650.
