Abstract

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.

Description

technical field [0001] The invention relates to a negative pressure adsorption device, in particular to a positive and negative paddle negative pressure adsorption device based on Bernoulli's principle. Background technique [0002] The wall-climbing robot is an automatic robot that can climb on the vertical wall and complete the work. The negative pressure adsorption method is a common adsorption method for the wall-climbing robot to climb on the vertical wall and complete the work. During negative pressure adsorption, propellers, etc. The negative pressure generator sucks the fluid to the suction cup, and the fluid inside and outside the suction cup generates a pressure difference, and the fluid presses the suction cup to realize the pressure and adsorption of the robot. The application number is CN201920267178.0, which discloses a negative pressure adsorption suction cup, including a power source and a suction cup. The mechanism realizes fluid suction and propulsion, and ...
