- the underwater sound frequency of the underwater sound signal can be constant or it can change with each emission or at a certain time.
- Underwater sound signal is to be understood in particular as the signal first emitted by the mobile water sound transmitter during a mission.” Multiple emission of the underwater sound signal "can be assumed if the mobile water sound transmitter has at least two temporally spaced apart ones
- a "sound transducer” is a device which in particular converts electrical energy into sound, in particular underwater sound, such as a piezoelectric transducer, for example a piezoceramic, to which a voltage is applied, and the reverse process can also be realized with the present sound transducer. so that an underwater sound signal applied to the transducer is converted into an electrical signal which can be processed and evaluated accordingly.
- a projector In the event that the sound transducer is designed only as a transmitter, this is referred to by a projector.
- the "power supply device” supplies both the sound transducer and the corresponding electronics, which controls the sound transducer or which evaluates corresponding signals applied to the sound transducer, with the associated supply voltage.
- the "locking device” is a device that provides physical contact between the mobile waterborne sounder and the corresponding one
- the mobile water sound transmitter is an integral part or a detachable-solid part of the corresponding underwater structure.
- the underwater structure can be either artificial underwater structures such as a pipeline or a wreck, as well as a natural structure such as a rock.
- the "firm connection” can be both substantially end-tight and releasably-strong, and the end-to-end connection essentially results in the removal of the mobile waterborne sounder, resulting in subsequent damage to the underwater structure, providing a releasably strong connection if due to appropriate forces of the mobile Water sound transmitter can be removed substantially without residue from the underwater structure.
- the locking device is a bolt setting device, in particular nail setter, a suction cup and / or a magnet, in particular an electromagnet.
- Underwater structure is ferrous and / or magnetic, One magnet or several magnets can be used.
- the connection can be solved without leaving any residue by switching off the electromagnet.
- the sound transducer can be set up such that the sound transducer is a time-regular
- Underwater sound signal transmits. For example, such an underwater sound signal can be emitted every 3 seconds. Due to this high repetition rate, a meaningful and fast activation can be realized, for example, by means of a ROV (remotely operated vehicle), which can then be controlled essentially directly on the mobile waterborne sound transmitter.
- ROV remotely operated vehicle
- the mobile water sound transmitter has a time delay device, in particular a time delay circuit, which delays the first time transmission of the underwater sound signal time.
- the energy consumption of the mobile waterborne sounder can be reduced or the duration of use extended accordingly.
- the mobile waterborne sounder may emit the first underwater sound signal, for example, for the next scheduled inspection. If this takes place, for example, in 2 or 3 weeks, the mobile can shortly before Waterborne sounder start sending out the first ping and the other pings.
- the mobile water sound transmitter In order to activate the mobile water sound transmitter only when needed, it may have an activation device which controls by an external signal, in particular external underwater activation sound signal, the first time transmission of the underwater sound signal.
- an external signal in particular external underwater activation sound signal
- a pipeline provided with the mobile waterborne sounder may, in the case of an inspection, be encoded by a correspondingly coded
- Underwater sound signal to be activated Due to the specific sequence of underwater activation sound signals and / or, for example, a frequency coding, individual mobile water sound transmitters can be activated so that they start to send the pings.
- the mobile water sound transmitter can be free from
- the mobile water sounder is on its essential components such as the power supply equipment, the transducer and the locking device and the corresponding electronics or control limited. Also, such a very inexpensive mobile water sound transmitter can be provided.
- the mobile water sound transmitter may have an envelope, which comprises a Wasserschallenendervolumen less than 12000cm 3 , in particular smaller 3000cm 3 or less than 900cm 3 and in particular smaller 150cm 3 .
- An "envelope” is defined in particular by the volume delimiting the outer surface or the housing surface of the mobile waterborne sounder.
- an unmanned underwater vehicle which comprises a previously described mobile
- the mobile waterborne sounders in the present case also called underwater sounders
- the mobile unmanned underwater vehicles After having been reached by the unmanned underwater vehicle the appropriate position for attaching or locking the mobile water sounder, the activation of the activation device, the firm connection with the underwater structure can be realized.
- unmanned underwater vehicles are both so-called ROVs, which are supplied by a cable connection, for example, with energy and / or information or AUVs, which can act autonomously under water.
- the mobile hydrophone transmitter is a detachable component of the unmanned underwater vehicle.
- the mobile waterborne sounder can be placed as a kind of mask on the unmanned underwater vehicle. This has the particular advantage that certain characteristics of the unmanned
- Underwater vehicle can be shared.
- this may provide a repulsion mass that improves the use of the nail setting device.
- the unmanned underwater vehicle can release the connection with the mobile hydrophone transmitter, and thus the hydrophone transmitter on the underwater structure remains and the unmanned underwater vehicle can be returned.
- the mobile waterborne sounder may also use data, energy or other means of the unmanned underwater vehicle
- the unmanned watercraft may have a supply line from the unmanned vessel to the mobile water sounder.
- this supply line may be electrical energy or it may also be a hydraulic line.
- the object is achieved by a watercraft, in particular a submarine, which has a mobile waterborne sound transmitter described above and / or a previously described unmanned underwater vehicle.
