When the windproof and energy-saving device is used for exhaust equipment such as forced exhaustion type gas water heaters, ventilators and the like, the device can lower the forced exhaustion power, reduce heat loss, realize energy conservation and carbon emission reduction, improve energy utilization rate, and reduce noise and pollution; and a rectangular or circular large-scale air-outlet windproof and energy-saving device which is formed by arranging and combining a plurality of air-outlet windproof and energy-saving devices and used for a rectangular or circular large-area air outlet has the advantages of small longitudinal size and attractive appearance.

The invention belongs to the field of bionics, and provides a bionic wall-climbing robot with self-adaptive wall surface roughness, which is rigid and soft combined with wet-absorbing feet, comprising tendons, lateral movement tendon branches, downward movement tendon branches, two claws, and a claw base. , foot frame, foot pad, liquid storage cavity, claw piece, vertical handle, elliptical flexible hinge; under the stretching of tendons, the two claws can hook the rough wall surface to crawl upward mechanical force; tendon stretching foot pad adsorption The wall surface with small roughness provides motion friction; tendon stretching means that the liquid in the liquid cavity is compressed into the foot pad, so that the folds on the surface of the foot pad expand and increase the contact area; the liquid is discharged to the contact surface along the micropores on the surface of the foot pad, Increase adsorption. When the tendons relax, the claws return to their original shape under the action of the flexible joints at the bottom, the liquid returns to the chamber, and the foot pads are separated from the wall surface to achieve rapid desorption. In this way, under the control of a tendon, it can automatically adapt to the wall environment of different roughness, quickly realize adsorption and desorption, and meet the motion requirements of the bionic wall-climbing robot.
