Description
Technical Field
[0001] The present invention relates to the technical field of in-situ observation instruments for fishery resources, and in particular to an underwater acoustic-optical dual-mode in-situ observation instrument for fishery resources. Background Art
[0002] In-situ observation instruments for fishery resources are mainly based on the integration of modern optical imaging technology and artificial intelligence technology. Their characteristics and advantages such as high-precision imaging and recognition, non-invasive monitoring, real-time and continuous monitoring, and wide applicability make them have broad application prospects and important scientific value in the fields of fishery resource management and ecological protection.
[0003] With the progress of technology and for the sustainable development of the ecosystem, during fishery catches, advanced in-situ observation instruments are usually used for observation to evaluate the quantity of fish stocks, individual sizes, etc. After obtaining the above information, the fish stocks are then selected for catching. However, existing observation instruments generally use cameras or acoustic detection methods for observation when in use. This method has a large error when used underwater and cannot accurately observe the specific information of the fish stocks. Moreover, most in-situ observation devices are designed for near-shore areas and have certain limitations in use.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] First, in the present invention, when using the underwater acoustic-optical dual-mode in-situ fishery resource observation instrument, the observation instrument is first installed in the catchable water area by means of a buoy, and multiple observation instruments are arranged in pairs during use to form diagonal observation. During observation, the observation instrument is provided with two cameras, forming a binocular camera distributed vertically to monitor simultaneously from above and below to compare differences, and at the same time, it is equipped with a sound wave monitor to improve the accuracy of monitoring.

[0022] Second, in the present invention, during use, the lower camera 1 mainly focuses on exploration. Through the four-way non-blind-zone detection in cooperation with the sound wave monitor, after detecting a fish school, it immediately rotates to a designated area for preliminary observation and locates the fish school. After determining the target, the upper camera 2 rotates as a whole to perform positioning and locking observation on this target until it is closed after fishing or giving up monitoring to save energy. During this period, camera 1 starts to cycle detection again, thus achieving the purpose of cycle detection and improving the detection efficiency.
[0023] Third, in the present invention, during use, the lower observation lower shell can be adjusted downward by an electric lifting rod, and can be adjusted to different heights according to the living habits of different fish schools for detection. At the same time, after adjustment, both cameras drive the function of adjusting the angle up and down, so as to accurately monitor the movement trend of the fish school. In cooperation with the adjustable function of the lower camera, after observing the appropriate fish school, the angle can be finely adjusted to track the position in real time, thus assisting in fishing. At the same time, through the linkage design with the buoy and the internal power supply system, the device can be put into any sea area according to requirements, so as to realize the in-situ observation of oceanic fishery resources.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1-7 , an underwater acoustic-optical dual-mode in-situ fishery resource observation instrument, comprising a buoy 1. A power supply system and a transmission system are arranged at the upper end of the buoy 1. Specifically, a tower 2 is fixed at the upper end on the buoy 1. A partition layer 3 is arranged on the tower 2, and different devices are installed on each partition layer 3, such as a main motor 4 and a transmission tower 5, etc. The transmission tower 5 transmits the observed data to a nearby fishing boat through a signal rod 6, and the main motor 4 draws power from a storage battery 19 to supply power to all components;
[0036] When in use, a rotating base 22 is provided at the lower end of the buoy 1. An electric lifting rod 7 is provided at the lower end of the rotating base 22. After the electric lifting rod 7 is started, it drives the adjusting base 8 at the lower end to perform lifting adjustment, relatively driving the protective partition net 9 to adjust. The observation lower shell 10 is fixedly installed on the protective partition net 9 and will also be adjusted. Especially when descending, the extension rod 15 provided at the upper end of the observation lower shell 10 will extend from the observation upper shell 11 to assist in adjustment. During the falling process of the protective partition net 9, it will protect the observation lower shell 10 from the bottom to avoid being impacted, etc. After descending, the target water area is observed through the camera one 13 and the acoustic monitor 14. Among them, four acoustic monitors 14 are provided. During the detection process, dead-angle-free acoustic detection is performed on the four surfaces centered on this device in the form of sound waves. After detecting a fish school, after the electric gear 26 is rotated, the main gear 25 is rotated, so that the circular observation area 24 is rotated, driving the camera one 13 to reach the position detected by the acoustic wave to perform a preliminary observation on the fish school, and judging whether the fish school has the need for fishing. If so, the camera two 12 is mobilized to this area for more accurate detection, and the data is transmitted to the monitoring room. The camera two 12 in the upper observation upper shell 11 will automatically adjust the angle to cooperate with the lower end for monitoring. After observing a suitable fish school, since the fish school is mobile, the provided adjusting motor 18 needs to be started. After the adjusting motor 18 is started, it will drive the connecting column 17 to rotate. Thus, the telescopic rotating rod 16 at the lower end of the connecting column 17 will drive the observation lower shell 10 to rotate up to 180°. During the rotation, the provided extension rod 15 will limit the rotation of the observation lower shell 10. The extension rod 15 rotates in the chute 23 on the observation lower shell 10, and the limit rotating shaft 20 will also rotate in the inner wall of the buoy 1 through the limit ring 21 to continuously monitor the fish school until it can no longer be monitored and then reset. Since multiple such buoys 1 are provided in a water area, synchronous monitoring will be performed in multiple directions, and the information will be transmitted to the fishing boat to assist in fishing;
[0037] If there is no need, the camera one 13 and the camera two 12 will work normally. The camera one 13 also performs circular observation in a rotating manner, cooperating with the acoustic monitor 14. When the camera two 12 is not in use, it can be in a closed state to save energy.
[0038] The working principle of the present invention is as shown in the figure. It includes a buoy 1. A power supply system and a transmission system are provided at the upper end of the buoy 1. Specifically, the iron tower 2 fixes the upper setting on the buoy 1. Different devices are installed on each layer 3 of the iron tower 2, such as the main motor 4 and the transmission tower 5, etc. The transmission tower 5 transmits the observed data to the nearby fishing boat through the signal rod 6, and the main motor 4 draws power from the storage battery 19 to supply power to all components;
[0039] When in use, a rotating base 22 is provided at the lower end of the buoy 1. An electric lifting rod 7 is provided at the lower end of the rotating base 22. After the electric lifting rod 7 is started, it drives the adjusting base 8 at the lower end to perform lifting adjustment, relatively driving the protective partition net 9 to adjust. The observation lower housing 10 is fixedly installed on the protective partition net 9 and will also be adjusted. Especially when descending, the extension rod 15 provided at the upper end of the observation lower housing 10 will extend from the observation upper housing 11 to assist in adjustment. During the falling process of the protective partition net 9, it will protect the observation lower housing 10 from the bottom to avoid being impacted, etc. After descending, the target water area is observed through the first camera 13 and the acoustic monitor 14. The second camera 12 in the upper observation upper housing 11 will automatically adjust the angle to cooperate with the lower end for monitoring. After observing suitable fish schools, since the fish schools are mobile, the set adjusting motor 18 needs to be started. After the adjusting motor 18 is started, it drives the connecting column 17 to rotate. Thus, the telescopic rotating rod 16 at the lower end of the connecting column 17 drives the observation lower housing 10 to rotate up to 180°. During the rotation, the set extension rod 15 restricts the rotation of the observation lower housing 10. Through the sliding groove 23 on the observation lower housing 10, the extension rod 15 rotates in the sliding groove 23, and the limit rotating shaft 20 also rotates in the inner wall of the buoy 1 through the limit ring 21 to continuously monitor the fish schools until the monitoring fails and then resets. Multiple such buoys 1 are set in a water area, so synchronous monitoring is carried out in multiple directions, and the information is transmitted to the fishing boat to assist in fishing.
