Embodiment 1

[0138] Such as Figure 1~2 As shown, an underwater bionic dolphin robotic device 1000 includes a main body unit 1100 , a tail fin unit 1200 , a pectoral fin unit 1300 , a floating unit 1400 , a center of gravity adjustment unit 1500 and a control unit 1600 . Wherein, the caudal fin unit 1200 is detachably arranged at the tail end of the main unit 1100, and it at least swings up and down to make the main unit 1100 move forward; the pectoral fin unit 1300 is symmetrically and detachably arranged on both sides of the main unit 1100, and its Rotate at least to make the main unit 1100 change the direction of movement; the floating unit 1400 is arranged inside the main unit 1100 for adjusting the weight of the main unit 1100 so that the main unit 1100 floats or sinks; the center of gravity adjustment unit 1500 is arranged on the main body The interior of the unit 1100 is used to adjust the center of gravity of the main unit 1100 so that the head end of the main unit 1100 remains hor...

Embodiment 2

[0269] This embodiment is a modified embodiment of Embodiment 1. The difference between this embodiment and Embodiment 1 lies in that the structure of the tail fin unit 1200 is different.

[0270] In the first implementation of this embodiment, the tail fin unit 1200 further includes a fourth driving element 1230, and the fourth driving element 1230 is respectively connected to the first driving element 1210, the tail fin element 1220, and is connected to the control unit 1600 for driving the tail fin. Element 1220 rotates.

[0271] Specifically, the fourth driving element 1230 is fixedly connected to the third bracket 1214 of the first driving element 1210 , and the output end of the fourth driving element 1230 is connected to the first connecting bracket 1222 .

[0272] Such as Figure 9a As shown, the fourth driving element 1230 includes a fourth driving motor 1231 , the fourth driving motor 1231 is fixedly connected to the third bracket 1214 , and the output end of the f...

Embodiment approach

[0275] In the second implementation mode of this embodiment, the tail fin unit 1200 further includes a fourth driving element 1230, and the fourth driving element 1230 is respectively connected to the tail end of the main body unit 1100, the first driving element 1210, and is connected to the control unit 1600. The tail fin element 1220 is driven to rotate.

[0276] Specifically, the fourth driving element 1230 is connected to the first installation element 1120 , and the output end of the fourth driving element 1230 is rotatably connected to the first bracket 1211 of the first driving element 1210 .

[0277] Such as Figure 9b As shown, the fourth driving element 1230 includes a fourth driving motor 1231 and a fourth bracket 1232 . Wherein, the output end of the fourth driving motor 1231 is connected to the first connection bracket 1222 ; the fourth bracket 1232 is fixedly connected to the first mounting element 1120 and the fourth driving motor 1231 respectively.

Abstract

The invention relates to an underwater bionic dolphin machine device and system. The device comprises a main body unit, a tail fin unit, a pectoral fin unit, a floating and sinking unit, a gravity center adjusting unit and a control unit. The system comprises a bionic dolphin machine device and a remote control device. The underwater bionic dolphin machine device has the advantages that through the floating and sinking unit, the self-weight is increased, meanwhile, the sealing structure of the main body unit is utilized, air in the main body unit is compressed, the effect of changing the self-weight is achieved, buoyancy is changed, and hovering is achieved; the gravity center is changed through the gravity center adjusting unit, so that floating and sinking actions are realized; the floating and sinking unit is matched with the gravity center adjusting unit, so that the freedom degree and flexibility of the bionic dolphin machine device moving in water are improved; the gravity center of the bionic dolphin machine device is at the lower half part, and balance can be achieved under the condition that the bionic dolphin machine device enters water at any angle.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an underwater bionic dolphin machine device and system. Background technique [0002] When conducting exploration, monitoring, and sampling in rivers, lakes, and seas, underwater operations are required, and staff are generally asked to dive. However, when encountering strong winds, rising water levels, and floods, potential safety hazards are prone to occur. [0003] When it comes to underwater operations, it is time-consuming and labor-intensive to drive professional boats or use manpower for underwater operations. Traditional propeller underwater robots are easily affected by aquatic plants, sand and stones. [0004] In order to solve the above problems, scientific research institutions and enterprises have developed many underwater robots to complete the above work. [0005] The Intelligent Bionic Machine Laboratory of Peking University School of Engineering has ...
