Embodiment Construction

[0022] Based on the principle that the pressure difference received by objects with different cross-sectional areas at both ends changes correspondingly when the external environment pressure changes, the invention develops a mechanical underwater depth-fixing releaser. The releaser does not need any sensor and electronic equipment, and the work is very reliable and stable. The following detailed description is given in conjunction with the accompanying drawings.

[0023] like Figure 1-2 As shown in the figure, a mechanical underwater depth fixing releaser includes a cylindrical shell 1, and a movable block 2 is arranged in the inner chamber of the shell 1. The cross-sectional areas of the two ends of the movable block 2 are different, and the bottom of the movable block 2 A trigger mechanism 3 is provided. The chamber inside the shell 1 is communicated with the external environment, that is, the movable block 2 is subjected to a pressure difference under the seawater press...

Abstract

The invention discloses mechanical underwater depth fixing releaser which includes a housing, A movable block is arranged inside the housing, the cross-sectional areas of the two ends of the movableblock are different, a triggering mechanism is provided at one end of the movable block, A water inlet hole is arranged on the housing, The movable block is subjected to pressure difference under seawater pressure, a first spring applied to the movable block and a reverse resistance to the pressure difference is arranged between the movable block and the shell, and with the change of seawater pressure, when the pressure difference reaches a set critical point, the movable block pushes the triggering mechanism to generate some mechanical actions, thereby completing the designated work. The releaser of the invention is mechanical, does not use any sensor and electronic equipment, works very reliably and stably, can be used for releasing and throwing loads at any depth under water, and has wide application range.

Description

technical field [0001] The invention relates to an underwater automatic release device, in particular to a mechanical underwater depth-fixing releaser. Background technique [0002] Submersibles or underwater profiling instruments used in ocean observations are equipped with releasers that can work at corresponding water depths. At present, the releaser mostly adopts an electronic control structure, which has relatively strict requirements on the external environment, and has problems such as complex circuit structure, high cost, and poor stability. SUMMARY OF THE INVENTION [0003] Based on the above technical problems, the present invention provides a mechanical underwater fixed depth releaser. [0004] The technical solution adopted by the present invention is: [0005] A mechanical underwater depth fixer and releaser comprises a casing, a movable block is arranged inside the casing, two ends of the movable block have different cross-sectional areas, a trigger mechani...
