Abstract
The invention relates to an acoustic beacon signal extraction device independent of an aqueous medium. An acoustically transparent polyurethane material is used as a sound transmission medium instead of the aqueous medium, and a signal trigger is used for triggering the water switch of an acoustic beacon to make the acoustic beacon work; the acoustic beacon is tightly attached to the acoustically transparent polyurethane material; and a signal extractor is vulcanized in the acoustically transparent polyurethane material and used for receiving and extracting an acoustic beacon signal. The acoustic beacon signal extraction device has the advantages that the device can activate the acoustic beacon to work and extract the acoustic beacon signal independent of the aqueous medium, and both the acoustic beacon and the device can work in the water-free state, thus being simple to operate and convenient to use.
Description
Technical field
The invention belongs to Underwater Acoustics Engineering technical field, relate to acoustic beacon signal extracting device, be related specifically to a kind of acoustic beacon signal extracting device being independent of aqueous medium.
Technical background
Acoustic beacon is a kind of device that can send acoustical signal in water, and its working method is to send the acoustic impluse signal of certain frequency, some cycles in water. In order to test acoustic beacon, it is necessary to activated and in running order by acoustic beacon, then extract the signal of acoustic beacon with corresponding signal receiving device, finally by signal evaluation circuit, it is determined that the duty of acoustic beacon. Due to acoustic beacon signal frequency and sound source level size, beacon signal is difficult in air dielectric to propagate extraction, and currently used underwater sound signal extracting mode is to put in water by acoustic beacon and signal extracting device, extracts signal in water. But, this mode is excessively loaded down with trivial details, not easily operates, and every time after detection, is attached to the water stain of acoustic beacon surface, also can affect duty and storage, the transport of acoustic beacon; Meanwhile, the water stain cleaning work on acoustic beacon also makes test job become complicated simultaneously, it is difficult to detect acoustic beacon quickly, in a large number.
Summary of the invention
It is an object of the invention to provide a kind of acoustic beacon signal extracting device being independent of aqueous medium, this device can when not having aqueous medium, acoustic beacon is excited to work, and can underwater sound signal be delivered in signal extracting device, solve acoustic beacon device signal extraction and rely on aqueous medium, operate an excessively loaded down with trivial details difficult problem.
The technical scheme is that employing entrant sound polyurethane material substitutes aqueous medium and becomes sound transmission medium, utilize signal trigger to trigger the taps of acoustic beacon so that it is work; Being close to by acoustic beacon on entrant sound polyurethane material, dector vulcanizes in entrant sound polyurethane material, receives and extract acoustic beacon signal.
Described sound transmission medium adopts entrant sound polyurethane material, use sulfuration process, pour into a mould sulfidization molding in a mold, and vulcanize according to the shape of acoustic beacon shell and acoustic beacon installing hole, the size of acoustic beacon installing hole is consistent with acoustic beacon shell sizes, after guaranteeing that acoustic beacon is installed, shell can be close on sound transmission medium.
Described signal trigger is made up of two contacts and relay, signal trigger is arranged on the bottom of acoustic beacon installing hole, and two contacts are stretched out from below, after acoustic marker inserts, contact can touch the two poles of the earth of the taps of acoustic beacon, and relay control signal triggers circuit work.
Described dector uses piezoelectric ceramics annulus, and overall sulfuration is in underwater sound transmission medium, and dector connects external circuit, is transferred out by the signal of extraction.
When carrying out acoustic beacon detection, by downward for its taps, insert in the installing hole of underwater sound transmission medium, signal trigger triggers acoustic beacon, make it start working, the acoustical signal of acoustic beacon is delivered to dector by underwater sound transmission medium and passes, it is achieved acoustic beacon is independent of the purpose of aqueous medium detection.
The invention have the advantages that this device can be independent of aqueous medium and activate acoustic beacon work, and extract the signal of acoustic beacon, acoustic beacon and this device all can work under anhydrous conditions, simple to operate, easy to use.
