Abstract

The invention relates to a manual ballast desertion device, which is characterized in that: the manual ballast desertion device comprises a driving mechanism, a desertion mechanism and a weight, wherein the driving mechanism is connected with an insertion pin through a steel cable; and when the weight is deserted, the driving mechanism pulls the insertion pin through the steel cable to make the weight get rid of the limitation of a rotary rod. The manual ballast desertion device has the advantages of good reliability and simple operation; when a hydraulic power source or a power supply is lost under emergency condition, the ballast can be quickly deserted manually, so that a submersible floats upwards quickly, the potential safety hazard is reduced, the loss of life and property is reduced and the emergency capacity is high; and in the ballast desertion operation, a handwheel is rotated positively and then rotated reversely to generate the driving force for derserting the ballast, so the potential safety hazard caused by misoperation of personnel is eliminated.

Description

technical field [0001] The invention relates to a ballast device, in particular to a manual ballast discarding device for a submersible. Background technique [0002] Deep-sea equipment such as diving bells, submarine rescue boats, and manned submersibles usually have one or more sets of ballast iron blocks. In an emergency or when it is necessary to obtain greater buoyancy after diving to a certain depth, the ballast iron is discarded to make the boat The body obtains enough positive buoyancy to safely return to the water surface or reach the set heavy buoyancy state. Whether the ballast can be safely and reliably discarded from the submersible is related to the emergency safety of the submersible and the operation of floating and diving. Therefore, the ballast discarding device must have extremely high reliability and emergency response capability. Existing ballast discarding devices usually use hydraulic cylinders to open the hook or electric explosion bolts to break the...
