Emergency locking device for fin instrument cabin of polar region scientific expedition ship

Abstract

The invention discloses an emergency locking device for a fin instrument cabin of a polar region scientific expedition ship. The emergency locking device comprises a cabin body and a deep well; the cabin body is located in the deep well; guiding plates are fixedly connected with the head end and the tail end of the cabin body through connecting columns; two guiding grooves are formed in the innerwall of the deep well; two guiding plates are located in the guiding grooves respectively; limiting blocks are fixedly connected with the same sides of the two guiding plates correspondingly; limitinggrooves matched with the limiting blocks are formed in the inner walls of the two guiding grooves correspondingly; the two limiting blocks and the two limiting grooves are located at the same horizontal height; fixed plates are fixedly connected with groove openings of the two guiding grooves correspondingly; extension mechanisms are arranged at the positions, corresponding to the fixed plates, at the groove openings of the two guiding grooves correspondingly; and the two connecting columns are positioned between the corresponding extension mechanisms and the corresponding fixed plates. The emergency locking device has the beneficial effects that in the ship body moving process, the stability of the cabin body can be well guaranteed, the cabin body is prevented from being impacted by water flow to collide with the inner wall of the deep well, and the safety of the cabin body is guaranteed.

Description

technical field [0001] The invention relates to an emergency locking device for a fin instrument compartment of a polar scientific research ship, belonging to the technical field of polar scientific research ships. Background technique [0002] Polar research ships are professional marine research ships that conduct marine surveys and surveys in the Arctic and Antarctic waters. It has the characteristics of strong hull, strong ice breaking ability and good cold resistance. The fin instrument compartments for underwater detection are usually installed in deep wells. [0003] When the scientific research ship moves on the sea surface, the fin instrument cabin is in a suspended state and will be impacted by the water flow, resulting in collision between the fin instrument cabin and the inside of the deep well, resulting in damage to the fin instrument cabin. Therefore, it is necessary to set up a Set the locking device for the fin instrument compartment to ensure the safety o...
