Background
When finless porpoise is searching for food, sound waves can be emitted, and the sound waves can be received by artificially distributed hydrophones, so that the finless porpoise can be used for researching the sound production characteristics of finless porpoise. If the observation time is long enough to cover a certain area, the method can be used for researching the number of the finless porpoise in the area, the activity rule and the like. At present, a lot of devices and methods for monitoring the finless porpoise by using self-contained hydrophones are available, when observation is needed, the self-contained hydrophones with preset monitoring programs are arranged under water and are recycled after a period of time, and then the sound production information of the finless porpoise can be obtained by using a data analysis method. The existing method has the defects that firstly, ships and people need to be sent to the site every time the cloth is placed and the recovery is carried out, and more manpower and material resources need to be consumed; secondly, the result of data analysis is always lagged, and the requirement of monitoring the activity of the finless porpoise in real time or quasi-real time is difficult to meet.
Disclosure of Invention

The invention is realized by the following technical scheme:
a finless porpoise underwater sound monitoring buoy is characterized in that the underwater sound monitoring buoy comprises a ship-shaped buoy body, a solar panel, an electronic bin, a hydrophone array, an anchor chain and a weight block;
the ship-shaped floating body provides buoyancy support for the whole buoy, and an anchor chain hanging point is arranged below the ship-shaped floating body;
the solar panel provides power supply for the electronic bin and is arranged above the ship-shaped floating body through the instrument bracket;
an electronic cabin is arranged in the ship-shaped floating body; the electronic bin comprises a hydrophone signal conditioning and collecting module, a signal processing module, a communication module and a power supply module; the hydrophone signal conditioning and collecting module is used for amplifying, filtering and collecting analog signals of the hydrophone; the signal processing module analyzes, processes and transmits the acquired signals in real time, and the communication module is used for communicating with the shore terminal; the power supply module can receive and store the electric power of the solar panel and supply power to other modules of the electronic bin;
the hydrophone arrays are arranged below the ship-shaped floating body, and the number of the hydrophone arrays is selected to be more than 3, so that the purpose of sound production positioning is achieved;
two ends of the anchor chain are respectively connected with the ship-shaped floating body and the weight, and a shock insulation measure is required to be made between rings of the anchor chain to prevent additional noise.
The weight realizes the fixation of the whole buoy system.
Further, the anchor chain is made of stainless steel material.
Furthermore, a shock insulation object is arranged between the rings of the anchor chain.
The utility model has the advantages of compared with the prior art:
the underwater sound monitoring buoy can obtain the sounding condition of marine mammals in the distributed sea area in real time; the hydrophone array is used, so that the purpose of positioning sounding can be achieved, and further the number of finless porpoises can be estimated to a certain extent; meanwhile, the whole system of the invention has controllable cost, reasonable and stable structural design and convenient maintenance.

Detailed Description
The technical solution of the present invention is further explained by the following examples, but the scope of the present invention is not limited in any way by the examples.
Example 1:
fig. 1 shows a schematic structural diagram of a finless porpoise underwater sound monitoring buoy. The ship-shaped floating body 1 provides buoyancy support for the whole buoy, and an anchor chain hanging point is arranged below the ship-shaped floating body; the instrument support is installed on the upper surface and used for fixing the solar panel 2, and the size and the number of the solar panel are selected according to the power consumption of the instrument.
The electronic cabin 3 is arranged in the ship-shaped floating body, and the electronic cabin 3 consists of four parts, namely a hydrophone signal conditioning and collecting module 7, a signal processing module 8, a communication module 9 and a power supply module 10, as shown in figure 2. The hydrophone signal conditioning and collecting module is used for amplifying, filtering and collecting analog signals of the hydrophone; the signal processing module analyzes and processes the acquired signal in real time, and when the finless porpoise click is detected, the signal is sent to a shore terminal through the communication module; the communication module is composed of a mobile phone network terminal and can be communicated with a shore terminal; the power supply module is a storage battery, can receive and store the electric power provided by the solar panel, and supplies power to other modules of the electronic bin.
The hydrophone array 4 is installed below the ship-shaped floating body and consists of 3 hydrophones at equal intervals, cables of the hydrophones are packaged in a stainless steel tube by using a vulcanization process, the hydrophones are arranged at the top end of the stainless steel tube, and the cables penetrate out of the other end of the stainless steel tube and are connected to the hydrophone signal conditioning and collecting module 7. This mode of installation facilitates routine inspection and maintenance, while taking into account the shock and noise reduction and robustness requirements.
The anchor chain 5 is connected with the ship-shaped floating body and the weight 6 and is generally made of stainless steel materials, shock insulation measures are needed to be made between rings of the anchor chain, and the anchor ring of the anchor chain is wound by adhesive tapes so as to achieve the purpose of eliminating noise. The weights are made of cement to provide the anchoring weight for the entire system.
