Piezoelectric-driven underwater detection robot

Abstract

The piezoelectric-driven underwater robot comprises a robot body, a piezoelectric propeller and a steering mechanism, the robot body comprises a shell, a power source and a main control module, the power source and the main control module are arranged in the shell, the shell is provided with a dorsal fin and a side fin which are used for keeping the posture stable, and the piezoelectric propeller is rotationally connected with the robot body; comprising a water inlet cabin, a water drainage cabin and a piezoelectric driving device arranged between the water inlet cabin and the water drainage cabin, the piezoelectric driving device is electrically connected with a main control module, the piezoelectric driving device is formed by compounding two piezoelectric patches, and high-frequency vibration energy generated by vibration acts on water flow flowing into the water inlet cabin, so that the water flow is sprayed out at a high speed from the tail of the water drainage cabin; therefore, high-speed advancing of the robot is achieved. The advantages of piezoelectric driving are fully applied to driving of the underwater robot, cavitation bubbles cannot be generated when the robot advances at a high speed, damage to a propelling system is avoided, maneuverability and maneuverability are high, rollover or rotation cannot occur underwater, and posture control is easy.

Description

technical field [0001] The invention relates to an underwater detection robot, in particular to an underwater detection robot capable of advancing at high speed. Background technique [0002] Most traditional underwater robots are driven by propellers, but when the required speed of the robot is fast, the high-speed rotation of the propellers will cause cavitation, which will easily lead to damage to the propellers and make the robot unable to drive. On the other hand, propellers are used for driving It is difficult to meet the needs of miniaturization and high-speed drive at the same time. With the application of underwater robots in recent years, the maneuverability of underwater robots has become more and more important in various performances. Propeller drive may no longer meet the needs of underwater robots. mobility needs. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide an underwater detection robot that does n...

[0002]Most traditional underwater robots are driven by propellers, but when the robot needs to travel at a high speed, the high-speed rotation of the propellers will cause cavitation, which will easily lead to propeller The damage of the robot caused the robot to be unable to drive. On the other hand, it is difficult to meet the needs of miniaturization and high-speed driving at the same time by using propellers. With the application of underwater robots in recent years, the maneuverability of underwater robots has become more and more important in various performances. The more important the position, the propeller drive may no longer be able to meet the mobility needs of underwater robots
