Problems solved by technology
When the vibration amplitude is large, the hydrophone cannot work normally, causing the received signal to be unstable or even lost
At present, the method of controlling the speed of the ship and adjusting the length of the tow is usually used to reduce the vibration of the linear hydrophone, but the effect is not good

The invention relates to a hydrophone device and a hydrophone system. The hydrophone device comprises a hydrophone and a spoiler, wherein the hydrophone comprises a hydrophone body and a signal cable;one end of the signal cable is connected with a signal processor disposed on a geophysical vessel and the other end is connected with the hydrophone body; the spoiler comprises a spoiler body and a spoiling wing plate; a first mounting hole is arranged in the spoiler body; the spoiler body sleeves the signal cable through the first mounting hole and is located between the hydrophone body and thesignal processor; and the spoiling wing plate is spirally wound on the spoiler body. The hydrophone system comprises the signal processor and the hydrophone device, wherein the hydrophone device is used for monitoring underwater acoustic wave signals through the hydrophone body and transmitting the underwater acoustic wave signals to the signal processor through the signal cable; and the signal processor is used for acquiring a detection result according to the underwater acoustic wave signals. The hydrophone device can ensure the stability of the detected acoustic signals, and the hydrophonesystem can ensure the reliability of the detection result.
Description
technical field [0001] The present invention relates to the field of marine science and technology, in particular to a hydrophone device and a hydrophone system. Background technique [0002] Offshore towed hydrophones are often used in offshore seismic exploration and engineering geophysical prospecting operations. The common operation method is to connect the hydrophone to the signal processor installed on the geophysical prospecting ship, and then tow the hydrophone to a certain distance below the sea level at the stern of the geophysical prospecting ship , to receive the acoustic signal. During the towing process, the hydrophone is often in a state of vibration due to the joint action of the stern current of the geophysical survey ship. When the vibration amplitude is large, the hydrophone cannot work normally, causing the received signal to be unstable or even lost. At present, the method of controlling the speed of the ship and adjusting the length of the tow is usua...
