Submersible ultra-deep protective device and method

Abstract

The invention belongs to the technical field of submersible ultra-deep protection and relates to a submersible ultra-deep protective device. The submersible ultra-deep protective device comprises an electronic protection unit, a mechanical protection unit and a floating load throwing unit. A protection method includes the steps that an MCU (Microprogrammed Control Unit) of the electronic protection unit determines whether a submersible works at the safety depth or not according to the working depth and the height to the bottom of the submersible, which are obtained through a depth meter and a height meter, and the MCU controls the floating load throwing unit to throw away a floating load if the working depth of the submersible is too large or the height to the bottom of the submersible is too small; a rubber pad of the mechanical protection enables a reed to perform elastic deformation to push a push rod to move through the pressure in deep water, and when the working depth is too large, a micro switch is touched to act and a normally closed contact is disconnected to throw away the floating load. The electronic protection unit and the mechanical protection unit are connected in series and the floating load throwing unit can be triggered to throw away the floating load when either the electronic protection unit or the mechanical protection unit is activated, so that the safety of the submersible is protected maximally, wherein the safe working depth / height of the submersible can be set according to the actual situation. The submersible ultra-deep protective device has high applicability.

Description

technical field [0001] The invention relates to a submersible ultra-deep protection technology, in particular to a submersible ultra-deep protection device and a protection method thereof. Background technique [0002] Ultra-deep protection technology has been widely used in the design of submersibles, and it is also an important indicator for evaluating the safety design of submersibles. At present, the usual implementation methods of ultra-deep protection technology are divided into control type and mechanical type. The control type is through the submersible. Realized by the control system of the submersible, the control system monitors the working depth and height from the bottom of the submersible in real time, and when the actual working depth is greater than the predetermined safety depth or the height from the bottom is less than the safety predetermined height, it will perform the load-throwing and floating action. This implementation method can realize The ultra-de...

[0002] Ultra-deep protection technology has been widely used in the design of submersibles, and it is also an important indicator for evaluating the safety design of submersibles. At present, the usual implementation methods of ultra-deep protection technology are divided into control type and mechanical type. The control type is through the submersible. Realized by the control system of the submersible, the control system monitors the working depth and height from the bottom of the submersible in real time, and when the actual working depth is greater than the predetermined safety depth or the height from the bottom is less than the safety predetermined height, it will perform the load-throwing and floating action. This implementation method can realize The ultra-deep protection of the submersible is far from enough for the safety design of the submersible. Once the control system is temporarily or permanently paralyzed, the submersible will lose its ultra-deep protection capability

The mechanical ultra-deep protection technology uses the mechanical pressure transmission device to use the pressure change as the control value of the micro switch. Once the pressure change exceeds the set value, the micro switch is triggered to perform the action of throwing up the floating ballast, but the mechanical There are many problems in the ultra-deep protection technology. It can only ensure that the working depth of the submersible does not exceed the set depth, but cannot make adjustments according to the actual water situation and the mission of the submersible.
