Built-in load underwater radial release device

Abstract

The invention discloses a built-in load underwater radial release device, and belongs to the field of underwater glider load release. The device comprises a frame structure, a door opening mechanism and a release mechanism, and the frame structure serves as one section of the NACA airfoil profile in the spanwise direction; the door opening mechanism comprises a fixed cabin door, a movable cabin door, a hinge mechanism and a rotating motor; the movable cabin door is hinged to the fixed cabin door through the hinge mechanism. Opening and closing of the movable cabin door are controlled through the rotating motor. The release mechanism comprises a control system, electromagnets and fixed clamping rings; the plurality of electromagnets are fixed on the movable cabin door; the electromagnets are placed in counter bores in the outer ring faces of the fixed clamping rings, the multiple fixed clamping rings are evenly distributed on the outer circumferential face of the load in the axial direction of the load, and the electromagnets and the counter bores are arranged in a one-to-one correspondence mode and can attract each other; the control system is used for controlling on-off of the electromagnets; when a Hall sensor senses an induction piece, the control system judges that the movable cabin door is opened to a designated position and also controls the electromagnets to be powered on and demagnetized, in other words, the attraction force between the electromagnets and the fixed clamping rings disappears, and the load is released.

Description

technical field [0001] The invention belongs to the field of underwater glider releasing loads, in particular to an underwater radial releasing device for built-in loads. Background technique [0002] The ocean is the space on which human beings depend for survival and development, and the strategic development base for energy, biological resources and metal resources, which is related to the survival and development of human beings. Due to the indiscriminate exploitation of resources by human beings, some resources are facing the problem of shortage. Therefore, more and more countries have begun to turn their attention to the ocean space which is rich in energy and resources. At present, all countries are actively carrying out marine surveys for the investigation of seabed and aquatic biomineral resources. Due to the harsh marine environment, autonomous unmanned exploration equipment is necessary for marine surveys. [0003] The underwater glider is a new type of underwate...

Problems solved by technology

The ejection mechanism carries the load and releases it vertically from basically the same height as the platform. After the load is released, it may collide with the platform due to the disturbance of the water flow. Moreover, the separation method between the load and the main body is not safe and reliable.
