An underwater protection device with a propulsion device for an underwater robot

Abstract

The invention relates to an underwater protection device with a propulsion device for an underwater robot, which includes a cover body. The outer wall of the cover is provided with a plurality of uniformly arranged water inlet holes, and the water inlet holes are fixed with the inner wall of the cover body. The fixed rod, the side wall of the water inlet is provided with an arc-shaped cavity, the fixed rod is fixed with a positioning rod in the same direction as the water inlet, the positioning rod is covered with a baffle plate slidingly connected with it, and the baffle plate There is a spring socketed on the outer wall of the positioning rod between the fixed rod and the spring is squeezed to cover the stop plate on the water inlet hole so that the surface of the cover body is smooth and the resistance is reduced for easy advancement, avoiding the uneven surface from affecting the advancement of the propulsion device and not It will affect the normal water intake of the water inlet hole. When the cylinder moves to the position of the water inlet hole, because the water pressure is greater than the pressure in the cover, the baffle plate will be opened to facilitate the internal water filling. When the cylinder is moved to a staggered position, the water inlet will be blocked. The hole stops water intake, and the buffer spring acts as a buffer to reduce the unstable shaking caused by the impact force generated when water rushes in.

Description

technical field [0001] The invention relates to the technical field of robot propulsion devices, in particular to an underwater protection device with a propulsion device for an underwater robot. Background technique [0002] An underwater robot is a mechanical device that can replace manual work underwater. Because it is more flexible and can complete more complicated work steps, it is called an underwater robot or an underwater working robot. It works underwater. It needs to have a propulsion device in order to increase its flexibility and adaptability, and it needs a protective device to protect it from damage caused by the propulsion device being wound around some unknown objects. [0003] The existing underwater robot propulsion device is simple, which leads to its single function and poor performance. Poor, it is easy to shake, which affects the more precise operation, and the water inlet hole is easy to be entangled and blocked by debris, which increases maintenance ...
