Description
Technical Field
[0001] The utility model relates to the technical field of marine engineering equipment, in particular to an adsorption-type acoustic behavior recorder for cetaceans. Background Art
[0002] In the field of underwater acoustics, marine organisms with their own acoustic characteristics, represented by cetaceans and dolphins, hold significant research value. Specifically, in underwater acoustic communication, the sounds produced by marine organisms' own vocal organs and the acoustic signals generated by other behaviors are significant sources of ocean background noise, and biological communities can also cause reverberation interference to active sonar. In underwater acoustic detection and identification, whales can use acoustic signals to identify and communicate with one another. In underwater acoustic positioning, the click signals emitted by dolphins while foraging can locate surrounding objects and detect and map the general outline of target objects. In short, cetaceans rely on sound to survive underwater, and biosonar enables them to communicate with each other, avoid predators, locate food, and migrate underwater, among other biological behaviors. The underwater acoustic detection and identification technologies used in this process are of great significance to the expansion of human acoustic research.
[0003] In order to study the correlation between the calls and behaviors of cetaceans and dolphins, it is necessary to simultaneously collect the sound and movement information of cetaceans. The traditional way to collect the acoustic and behavioral characteristics of cetaceans is to use a hydrophone array to collect the sound information of cetaceans over a large area. However, the fixed hydrophone array has a low signal-to-noise ratio due to the long distance. At the same time, since the hydrophone body is not associated with the cetaceans, it cannot collect specific movement information. Therefore, there is an urgent need for a device that can be attached to the cetaceans and automatically detached from the cetaceans to record the acoustics and behavior of cetaceans to solve the above difficulties.

The suction cup is flexible and will not cause harm to the cetacean, reflecting its bio-friendliness. The simple structure and the electrochemical corrosion characteristics of magnesium metal are used to achieve the release of the suction cup, with low cost and high reliability.

The attachment adopts a suction cup negative pressure adsorption, has a strong ability to resist horizontal lodging, and can effectively reduce the device from falling off due to the rapid swimming of cetaceans; a PU tube 11 is connected to the top; the PU tube 11 is connected to the inside of the watertight connector 5 and the suction cup 4; the connection holes 17 opened on the left and right edges of the upper shell 1 and the lower shell 3 are set to two, and correspondingly, the suction cup 4 and watertight connectors 5 are each provided with two, and the PU tube 11 is provided with two; the PU tube 11 is a bendable PU tube 11; the four suction cups are divided into two groups and distributed to the side positions of the equipment, and are distributed in a support manner to balance the forces on both sides; the binding hole 6 is penetrated by a cable tie 8, the cable tie 8 restrains the PU tube 11, and the other end of the cable tie 8 is tied with a threaded magnesium rod 14, and the two ends of the threaded magnesium rod 14 are threadedly connected with a connecting buckle 13, and the cable tie 8 passes through the connecting buckle 13 to be tied with the threaded magnesium rod 14; the cable ties 8 on both sides of the shell are tightened by the threaded magnesium rod 14 so that the PU tube 11 is bent so that the inside of the PU tube 11 is not connected, and the threaded magnesium rod 14 is located above the electrochemical corrosion hole 15;The upper housing 1 is provided with a positive electrode 9 and a negative electrode 16 for detecting water inflow and outflow, respectively, on the left and right sides.

The positive and negative electrodes 9 and 16 are electrically connected to the control board to form a circuit for detecting water inflow and outflow. The copper negative electrode in the electrochemical corrosion hole 15 is electrically connected to the control board. When the control board is powered on, the copper negative electrode in the electrochemical corrosion hole 15, the seawater, and the positive electrode for detecting water inflow and outflow form a circuit, thereby accelerating the corrosion of the threaded magnesium rod 14 above the electrochemical corrosion hole 15 and causing it to break quickly (in about 5 minutes). As the threaded magnesium rod 14 breaks, the PU tube 11 returns to its original position and no longer bends. At this time, seawater enters the suction cup 4 from the exposed opening of the PU tube 11, causing the suction cup 4 to fall off the cetacean.
[0025] The working principle and use process of this utility model:

At this time, the cable tie 8 restrains the PU tube 11, and the cable ties 8 on both sides of the shell are tightened by the threaded magnesium rod 14 to make the PU tube 11 bent, so that the inside of the PU tube 11 is not connected; when in use, the entire device is dropped by a drone, a javelin, a dropping rod, etc. to make the suction cup 4 adsorbed on the smooth surface of the cetacean (because the PU tube is tightened and bent by the threaded magnesium rod 14, the inside is not connected, so that the suction cup 4 is adsorbed on the surface of the cetacean due to the internal pressure); while the device floats and sinks with the cetacean, the hydrophone 2 and the temperature and pressure sensor 12 collect acoustic signals The signal and sensor information are recorded and stored. After a collection period, the copper electrode in the electrochemical corrosion hole 15 is energized through the control board in the built-in chamber. The copper negative electrode in the electrochemical corrosion hole 15, seawater and the positive electrode 9 for water inlet and outlet detection form a circuit, thereby accelerating the corrosion of the threaded magnesium rod 14 above the electrochemical corrosion hole 15, causing it to break quickly (about 5 minutes); as the threaded magnesium rod 14 breaks, the PU tube 11 is not tightened by the threaded magnesium rod 14, so the PU tube 11 is reset and no longer bends. At this time, seawater enters the suction cup 4 from the other end of the PU tube 11, causing the suction cup 4 to fall off the cetacean; at the same time, the control board switch circuit turns on the GPS positioning and VHF transmission module for equipment recovery.
