Problems solved by technology

The sucker structure prepared by the above method shows excellent reversible adsorption and desorption performance under water, but it often needs external force to realize it, and it is impossible to rely on the material itself to achieve controllable adsorption and desorption.
[0005] At present, there are few reports on the autonomous controllable adsorption and desorption of underwater biomimetic adhesive structures.

Abstract

The invention belongs to the technical field of adsorption structures, and relates to a controllable underwater bonding device which comprises a bonding suction cup and an air pump regulation and control system. The bonding suction cup and the air pump regulation and control system are connected through a soft guide pipe, the bonding suction cup can achieve underwater contact and adsorption with an object interface, the radius is 4-30 mm, and the height is 1-20 mm; the air pump regulation and control system controls the internal pressure of the bonding suction cup through air suction and air inflation, and controllable adsorption and desorption of the bonding suction cup are achieved; during use underwater, the bonding suction cup is adsorbed to the surface of an object, then an air inflation / air suction pump and a valve are opened at the same time through a controller, the air inflation / air suction pump conducts air suction, negative pressure appears in the bonding suction cup, and therefore, the adsorption strength of the bonding suction cup is improved; when the air inflation / suction pump injects air into the bonding suction cup, the negative pressure in the bonding suction cup disappears, and the bonding suction cup is autonomously desorbed from the surface of the object; and the controllable underwater bonding device is simple in structure, convenient to manufacture and capable of achieving controllable adhesion and desorption underwater.

Description

Technical field: [0001] The invention belongs to the technical field of adsorption structures, and relates to a controllable underwater bonding device, specifically a bonding device imitating the structural characteristics of an octopus sucker, whose adhesion and desorption are controlled pneumatically, and are especially suitable for underwater environments . Background technique: [0002] Traditional adhesive materials mainly rely on mechanical interlocking or molecular attraction between the adhesive structure and the surface of the object to achieve adhesion. However, once it encounters liquid, it will often lead to problems such as a decrease in bonding strength and a shortened service life. Especially in a water environment, the use of traditional bonding materials is even worse. [0003] Octopuses are common marine molluscs with eight arms, each of which is covered with conical suction cups. Through these conical suction cups, octopuses can grab objects arbitrarily u...
