An up-floating and down-dive submerged ballast discarding device

Abstract

The invention discloses an up-floating and down-dive ballast discarding device, which comprises a frame, a screw rod, a top plate, a pressing iron and a thrust bearing. The top plate is suspended on the frame for carrying the weight of the ballast; The upper part of the screw rod is a shaft shoulder, the upper part of the shaft shoulder is a top optical axis, and the lower part of the shaft shoulder is a trapezoidal thread; The shaft shoulder is seated on the thrust bearing, and the thrust bearing is seated on the top plate; The center of the pressing iron is provided with a trapezoidal threaded hole, and the parameters such as the profile, the lead and the screw pitch of the trapezoidal threaded hole are coupled with the trapezoidal threads of the screw threads, and the pressing iron rotates through the trapezoidal threads and is self-locked on the screw threads. The invention can finely control the weight of discarded ballast, reduce the intervention time of the buoyancy adjustment system and facilitate the adjustment of zero buoyancy by adjusting the weight and the quantity of the single press iron.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and relates to a manned submersible, in particular to a jetting device for floating and submerging ballast. Background technique [0002] Since the operational manned submersible needs to have a large underwater load capacity and the need for fast unpowered up and down dives, it is necessary to configure a larger weight of ballast. [0003] The existing floating and diving ballasts are usually equipped with two pieces (left and right symmetrical arrangements), and the corresponding dumping mechanism needs four sets. hundred kilograms. The problem is: firstly, when dumping the load, the submersible will shake violently, which is a potential danger; secondly, after the entire piece of ballast is discarded, if the submersible does not reach the expected zero buoyancy state, the buoyancy adjustment system needs to intervene ; Again, multiple sets of dumping mechanisms have improved the ...

Problems solved by technology

The problem is: firstly, when dumping the load, the submersible will shake violently, which is a potential danger; secondly, after the entire piece of ballast is discarded, if the submersible does not reach the expected zero buoyancy state, the buoyancy adjustment system needs to intervene ; Again, multiple sets of throwing mechanisms have increased the requirements for the system. If one of them fails to work, the submersible will inevitably be out of balance, increasing the risk of underwater operations

But the problem is that the steel balls are easy to rust in seawater and form a ball, which affects the dumping effect. In order to maintain the magnetic field of large-mass steel balls, the electromagnetic coil needs to be continuously powered and the current is large. For today's limited underwater batteries Capacity is a huge challenge
