The invention relates to a positive and negative paddle negative pressure adsorption device based on a Bernoulli principle. The adsorption device comprises a main frame, a power motor, a power input shaft, a contra-rotating generation mechanism, a forward propeller power output shaft, a reverse propeller power output shaft, a forward propeller, a reverse propeller and a support. The contra-rotating generation device converts one-way rotating torque transmitted from the power input shaft into positive and negative two-way rotating torque. The positive propeller power output shaft is of a hollowshaft structure; the upper end is connected with the contra-rotating generation mechanism; the reverse propeller power output shaft is of a solid shaft structure; the upper end of the reverse propeller power output shaft penetrates through the forward propeller power output shaft and is connected with the contra-rotating generation mechanism; strict same rotating speed and opposite rotating directions of the positive and negative paddles are realized; the forward rotating torque generated by the forward paddle and the reverse rotating torque generated by the reverse paddle are mutually counteracted, and the forward paddle and the reverse paddle adopt the propellers with opposite spiral coefficients, so that the fluid movement directions are consistent, the fluid acceleration enhancement effect is achieved, and the negative pressure adsorption efficiency is improved.

    本发明涉及一种基于伯努利原理的正反桨负压吸附装置,所述吸附装置包括主框架、动力电机、动力输入轴、对转发生机构、正桨动力输出轴、反桨动力输出轴、正桨、反桨和支架组成,对转发生装置将从动力输入轴传递的单向转动力矩转换为正反双向转动力矩,正桨动力输出轴为空心轴结构,上端与对转发生机构连接,反桨动力输出轴为实心轴结构,反桨动力输出轴上端穿过正桨动力输出轴与对转发生机构连接,实现正反桨的严格相同转动速度和相反转动方向,不仅保证了正桨产生的正向旋转力矩与反桨产生的反向旋转力矩相互抵消,而且由于正桨和反桨采用相反螺旋系数的螺旋桨,从而使流体运动的方向一致,起到流体加速增强效果,提高了负压吸附效率。
