Description

Underwater active monitoring-based underwater acoustic transducer

Technical Field

The utility model belongs to underwater acoustic transducer field, concretely relates to underwater acoustic transducer based on active interception under water.

Background

The underwater acoustic transducer operates by utilizing the piezoelectric effect of crystal (quartz or potassium sodium tartrate) piezoelectric ceramics (barium titanate, lead zirconate titanate, and the like) or the magnetostrictive effect of iron-nickel alloy, namely, the piezoelectric effect is that a crystal is cut into thin sheets in a certain direction, pressure is applied to the crystal thin sheets, and positive charges and negative charges are respectively generated on two end faces of the crystal thin sheets.

However, when the underwater acoustic transducer is actively monitored, in order to avoid the bolt from damaging the receiving surface of the underwater acoustic transducer, most of the underwater acoustic transducers are fixed by using a mold and a tool, but the mold is easy to slip off from the underwater acoustic transducer, and the mold is worn for a long time, so that the service life of a shell of the underwater acoustic transducer is easily influenced, and therefore the underwater acoustic transducer based on the underwater active monitoring is required to solve the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an underwater acoustic transducer based on active interception under water can carry out spacing fixed with the fixture block on underwater acoustic transducer through the draw-in groove, avoids the fixture block to slide on underwater acoustic transducer easily, leads to droing of fixture block, sets up the rubber pad through the interior table wall at the fixture block, can prevent that the fixture block from long-term in underwater acoustic transducer's outward appearance wall sliding friction, influences the life of underwater acoustic transducer casing easily.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model relates to an underwater acoustic transducer based on active interception under water, including the underwater acoustic transducer body, the top of underwater acoustic transducer body is provided with the connector, and the outward appearance wall of underwater acoustic transducer body has seted up the draw-in groove, the inside block of draw-in groove is connected with the fixture block, the both sides of fixture block all are provided with the dead lever, two the below of dead lever all is provided with the connecting rod, two the below of connecting rod is provided with the mounting panel, the interior table wall of fixture block is provided with the rubber pad.

As an optimal technical scheme of the utility model, fixture block and rubber pad are pasted fixedly through glue.

As an optimized technical scheme of the utility model, the mounting panel is the cylinder structure.

As an optimized technical scheme of the utility model, four mounting holes have been seted up on the mounting panel, and four mounting panels are the annular form and distribute.

As an optimal technical scheme of the utility model, fixture block and draw-in groove looks adaptation.

Compared with the prior art, the beneficial effects of the utility model are that:

the clamping block can be limited and fixed on the underwater acoustic transducer through the clamping groove, so that the clamping block is prevented from easily sliding on the underwater acoustic transducer to cause the clamping block to fall off.

The rubber pad is arranged on the inner surface wall of the clamping block, so that the clamping block can be prevented from sliding and rubbing on the outer surface wall of the underwater acoustic transducer for a long time, and the service life of the casing of the underwater acoustic transducer is easily influenced.
