Problems solved by technology
This underwater acoustic release system receives / sounds signals through the acoustic transducer, and can determine the slant distance between the above-water machine and the underwater machine, but cannot accurately locate the underwater machine, so it cannot precisely control the underwater machine's working position. Depth, at the same time, due to the complexity of the system design, it is expensive, and the short-term test is not cost-effective

Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0017] The invention provides an underwater release device for a self-floating test. The release device has a simple and firm structure and is easy to operate, and can realize automatic release of heavy objects when the depth is set underwater.
[0018] The release device includes a trigger mechanism, a drive mechanism, a release mechanism and a tool housing. When in use, the release device is installed at the tail of the self-floating test model. In order to ensure the smooth shape and structure of the self-floating test model, the tooling shell and the self-floating test model are designed in an integrated way, so that its external dimensions are the same as those of the self-floating test model. Dimensions match. The tooling housing is an inverted cone structure, and the trigger mechanism and the driving mechanism are located in corresponding mounting ...

The invention discloses an underwater release device, which is controlled by a mechanical principle and can effectively realize the automatic release of heavy objects at a set depth underwater. It specifically includes trigger mechanism, drive mechanism, release hook and tooling housing. In the release device, the trigger response of the trigger mechanism is transmitted to the spring sleeve of the drive mechanism through the trigger rod, and then the constraint of the spring sleeve is released. During the spring stress release process, the spring sleeve is pushed to move laterally to form the drive mechanism. force to drive the release shaft to rotate around the release shaft shaft, so that the release hook is separated from the release shaft to realize the release function.
Description
technical field [0001] The invention relates to a release device, in particular to an underwater release device, and belongs to the technical field of vibration and noise testing. Background technique [0002] When the underwater vehicle is running at high speed, the hydrodynamic noise is an important radiation noise source. In order to verify the hydrodynamic noise characteristics of the underwater vehicle by means of tests, two test methods, shallow water dragging and deep water flotation, are usually used to test the model. test. Among them, the deep water floating test connects the test model and the ballast weight through the underwater release device. Under a certain water depth, the underwater release device works to separate the test model from the ballast weight. Under the action of the positive buoyancy of the model itself, The model is accelerated to float up to realize the hydrodynamic noise test at a higher speed of the model. [0003] At present, the acoustic...
