Specific implementation mode
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the underwater robot external shell that the present invention imitates jellyfish movement includes 1 He of hemisphere translucent cover on top The conical shell 10 of lower part, the two hollow outer sealing, carries out water-proofing treatment.It is fixed with inside hemisphere translucent cover 1 fixed flat Platform, each solar panel 2 cut oblique placement in 45 degree of angles with fixed platform, are uniformly distributed and face four direction.Under fixed platform Aspect is equipped with swing steering engine 3, and rotate gear is fixed in 3 rotation axis 11 of swing steering engine.Turn to iron block 5 by particularly customized, It is welded on a rigidity to swing on iron, similar iron hammer shape is fixed in the rotate gear of swing steering engine 3, works as swing steering engine It when receiving instruction and turning an angle, correspondingly rotates gear and can drive and turn to iron block 5 and turn an angle, as shown in Figure 5.Such as Shown in Fig. 2,1 lower end of hemisphere translucent cover is uniformly distributed along the circumference 6 and drives steering engine 9(The driving steering engine uses waterproof construction, is set to underwater The hull outside of robot), swing flabellum 7 and be nested in the rotation axis 11 of corresponding driving steering engine 9, driving steering engine passes through certain angle The rotation of degree, which drives, swings the swing certain angle of flabellum 7, as shown in Figure 6.Meanwhile being fixed with main control in hemisphere translucent cover 1 Plate 4 and power supply 6, power supply 6 can carry out charging replacement, the service life was up to 2 years or more using the lead-acid accumulator of 12v.Simultaneously Solar panel 2 is connected with power supply 6 by power management module, and voltage conversion is carried out in module.Power management module includes Input/output module, Voltage stabilizing module, module for metering electric quantity, solar panel pass sequentially through input/output module, Voltage stabilizing module Power generation electricity is stored into accumulator, accumulator is exported by Voltage stabilizing module and module for metering electric quantity to control panel and steering engine etc. Electrical appliance is powered, specifically, Voltage stabilizing module powers the power conversion of 12v at the voltage of other circuits, such as 3.3v of controller It powers etc. with the 5v of steering engine;Input/output module correspond to respectively 3.3v, 5v and 12v power interface;Module for metering electric quantity can be with The electricity of current storage is fed back to master board.When electric quantity of power supply exhausts, generated electricity to accumulator by solar panels Charging.As shown in Figure 2.Master board 4 is connected with each steering engine(Including swing steering engine and driving steering engine), control steering engine operating.Under Portion's conical shell 10 is fixed at 1 lower end of hemisphere translucent cover, and lower inside center position is fixed with heavy burden iron block 8, this is negative Weight iron block 8 is remained unchanged relative to the external of conical shell 10.When heavy burden iron block 8 and the line and conical shell that turn to iron block 3 When 10 coaxial line, the height at the top of iron block 3 to hemisphere translucent cover 1 is turned at a distance from heavy burden iron block 8 to 1 top of hemisphere translucent cover Than being 1:3.
Underwater robot can also carry underwater ultrasound sensor, camera and all kinds of detection sensors simultaneously, carry out obstacle Object is hidden to be explored with seabed.Detection sensor such as depth transducer obtains bathymetric data by detecting current hydraulic pressure;Or water quality Sensor can detect the data such as pH value and the dissolved oxygen of seawater.
As shown in figure 4, the course of work of underwater robot is as follows:When underwater robot enters water, swings flabellum 7 and hang down position In the peripheral side of conical shell 10, underwater robot is integrally conical state, and due to the presence of heavy burden iron block 8, this body weight is big It, can submerged in the buoyancy of water.Master board sends out work order, and six driving steering engines rotate certain model with certain frequency It encloses, the effect brought, which is the swing flabellum 9 of connection, to be swung up and down, to push underwater robot to move, motion principle and water Female opening and closing tentacle movement is consistent.When there is barrier in front, the underwater ultrasound sensor of carrying can detect, send a signal to master Control panel 4 sends out instruction by master board 4, and swing steering engine 3 is allowed to rotate, and turning to iron block 5 can also shift so that half ball cover Center of gravity deflects(As shown in Figure 3), to realize divertical motion.The 6 serial electric quantity metering module of power supply of underwater robot simultaneously(It should Module for metering electric quantity is by integrated sample resistance, the size of current flowed through by resistance test unit interval inner looping, electric current It changes over time, will produce different pressure differences after flowing through different electric currents, integrated, obtained by the electric current that this is changed The electricity of present battery).The master board 4 of underwater robot detects whithin a period of time, when supply current is less than normal value, System judges that robot electric quantity is remaining insufficient, charges.At this moment master board 4 sends out control instruction, adjusts driving rudder Machine, which slowly rotates, makes swing flabellum open, and the buoyancy suffered by robot can be increasingly greater than gravity itself at this time, slowly floats, until On climbing up on top of the water completely, the solar panel 2 of carrying can carry out charging operation, ensure the long-time continuation of the journey of underwater robot Work.
