TECHNICAL FIELD
[0001] The utility model belongs to the technical field of deep sea and far sea culture work ship, and relates to a fish driving and gathering and catching auxiliary structure and system for a culture work ship. BACKGROUND
[0002] With the decline of marine fishing yield and the deterioration of nearshore ecosystem, people's demand for healthy and green marine products is growing, which promotes the marine aquaculture industry to gradually enter the deep blue sea area. The deep sea and far sea culture of large quantities of fish with good economic benefits by using high-quality water resources in the deep sea and far sea is an important way to expand the culture area and improve the yield of marine products. As a new type of deep sea and far sea culture equipment, the culture work ship has the advantage of avoiding disasters such as typhoon and red tide compared with the traditional culture platform. At present, the world's first 100,000-ton culture work ship operated by the applicant has been put into production. The ship is provided with 15 large culture cabins, the culture cabin is in the shape of a wide-mouthed bottle, the inner wall is smooth, the size of a single culture cabin is about 20m in length, 20m in width and 19m in height, the water depth in the cabin is 14m, the culture water of a single culture cabin is about 5600 square meters, and the main culture variety is large yellow croaker. This variety is sensitive to sound, and the traditional culture and fishing industry drives and catches large yellow croaker by knocking bamboo poles to produce noise, but this traditional method cannot be applied to the culture cabin environment of the culture work ship. At present, the culture work ship mainly drives and catches large yellow croaker by knocking the cabin wall with a metal block to produce vibration noise when the cabin is caught. The driving and catching by this method has the following shortcomings:
[0003] (1) Since the cabin wall of the culture work ship is made of metal steel as a whole, there is no other material buffer between the cabins, and the vibration produced by knocking the metal cabin bottom during catching will be directly transmitted to other cabins, which will cause strong stimulation to the cultured fish in other cabins that have not been caught, resulting in stress and even death.
[0004] (2) In order to prevent seawater erosion, the inner wall of the culture cabin is coated with a protective coating. Long-term and repeated knocking of the culture cabin bottom with a metal block will damage the coating on the cabin wall, resulting in corrosion of the culture cabin and safety hazards such as water leakage.
[0005] (3) After repeated catching and knocking, large yellow croaker will gradually adapt to the vibration noise produced by knocking, resulting in no stress and floating in the later stage, which reduces the catching efficiency.
[0006] (4) Since large yellow croaker needs to be caught in a light-shielded environment, the traditional driving method cannot judge the number of gathered fish groups, and too much driving will lead to failure to catch in time, and the fish groups will be damaged due to friction in the fishing net; too little driving will reduce the catching efficiency and increase the labor intensity. INVENTION CONTENTS
[0007] In view of the above prior art, the fish driving and catching auxiliary structure and system for the culture work ship provided by the utility model make use of automatic equipment to replace manual metal block knocking to drive large yellow croakers, and positively assist the catching of the large yellow croakers.
[0008] The utility model provides a kind of fish driving and catching auxiliary structure for culture work ship, including lifting assembly and functional assembly;
[0009] The lifting assembly includes a guide, a lifting member and a drive member, and the drive member is used to drive the lifting member to lift along the guide;
[0010] The functional assembly includes an underwater camera and an underwater transducer mounted on the lifting member.
[0011] As a preferred scheme, the guide is a slide rail vertically installed on the inner wall of the culture cabin of the culture work ship.
[0012] As a preferred scheme, the lifting member is a sliding block connected to the slide rail.
[0013] As a preferred scheme, the drive member is an electric winch arranged at the top of the slide rail and an umbilical cable wound on the electric winch, and the umbilical cable is electrically connected with the underwater camera and the underwater transducer.
[0014] The utility model also provides a fish driving and catching auxiliary system for culture work ship, which includes a plurality of groups of the above fish driving and catching auxiliary structure.
[0015] As a preferred scheme, the number of the fish driving and catching auxiliary structure is 3-8 groups, which are evenly distributed on the inner wall of the culture cabin of the culture work ship.
[0016] As a preferred scheme, the system further includes a water control mechanism, which is used to control the drive member and the functional assembly in each group of the fish driving and catching auxiliary structure.
[0017] As a preferred scheme, the water control mechanism includes a control unit, a display and a keyboard, wherein the display, the keyboard, the drive member and the functional assembly are electrically connected with the control unit.
[0018] As a preferred scheme, the system further includes a power supply assembly, which supplies power to the water control mechanism, the drive member and the functional assembly.
[0019] The utility model has the following beneficial effects:
[0020] (1)The sound wave generated by the underwater transducer mainly propagates underwater, has less influence on other culture cabins connected to the whole ship, and can avoid the stress reaction of the cultured fish in the cabin that does not perform catching.
[0021] (2)The fish driving and catching auxiliary structure is uniformly arranged on the inner wall of the culture cabin, and the underwater transducer can move up and down through the lifting assembly. Compared with the original fixed-point knocking of the metal block, the action range is wider and the driving efficiency is better. On the other hand, it can also avoid the damage of the original fixed-point knocking of the metal block to the coating of the culture cabin, prevent the damage of the cabin wall, and eliminate the safety hazard.
[0022] (3)The underwater camera and the underwater transducer are used in cooperation, which can effectively estimate the number of driven fish groups and prevent the problem of too much or too little catching.
[0023] (4)The frequency of the sound wave released by the underwater transducer can be adjusted through the water control mechanism. When the large yellow croaker adapts to a certain frequency of sound wave and the driving efficiency decreases, other frequency of sound wave can be replaced to ensure the driving effect.

[0033] Example 1:
[0034] like Figures 1-4 As shown, a fish-driving and aggregating auxiliary structure for aquaculture vessels includes a lifting component and a functional component.
[0035] The lifting assembly includes a guide, a lifting component, and a driving component, wherein the driving component is used to drive the lifting component to move up and down along the guide;
[0036] In one embodiment, the guide is a slide rail 2 vertically installed on the inner wall of the aquaculture compartment 1 of the aquaculture vessel; correspondingly, the lifting component is a slider 3 slidably connected to the slide rail 2. The driving component is an electric winch 4 installed at the top of the slide rail 2 and an umbilical cable 5 wound on the electric winch 4.
[0037] The functional components include an underwater camera 6 and an underwater transducer 7 mounted on a slider.
[0038] As one implementation method, the underwater camera 6 is equipped with night vision function to meet the actual working needs of the aquaculture tank 1.
[0039] In order to meet the electrical connection between the umbilical cable 5 and the underwater camera 6 and the underwater transducer 7, as an embodiment, a junction box is arranged on the sliding block 3, and the umbilical cable 5 is electrically connected with the underwater camera 6 and the underwater transducer 7 through the junction box.
[0040] As an embodiment, the sliding block 3 is provided with a mounting portion for mounting the underwater camera 6, the underwater transducer 7 and the junction box, and the underwater camera 6, the underwater transducer 7 and the junction box are detachably connected with the mounting portion.
[0041] The embodiment also provides a fish driving and gathering auxiliary system for a fish farming vessel, which comprises four groups of the above-mentioned fish driving and gathering auxiliary structures, and is uniformly distributed on the inner wall of the culture cabin 1 of the fish farming vessel, so as to ensure that the sound waves emitted by the underwater transducer 7 can fully cover the cross section of the culture cabin 1.
[0042] As an embodiment, the system further comprises a water control mechanism, which is used for controlling the electric winch 4, the underwater camera 6 and the underwater transducer 7 in each group of the fish driving and gathering auxiliary structures. Specifically, the water control mechanism can control the electric winch 4 to wind or unwind the umbilical cable 5 to realize the lifting of the sliding block 3 and the functional components on the sliding block 3, control the wavelength, frequency and other parameters of the sound emitted by the underwater transducer 7, and can also observe the gathering state of the underwater fish group through the underwater camera 6 and estimate the number of the fish group in a specific water layer through dynamic identification.

[0047] (2) When the underwater camera 6 observes that the fish group at the bottom of the cabin moves to the water surface, the water control mechanism controls to start the electric winch 4, and the sliding block 3 is slowly moved to the water surface under the action of the umbilical cable 5, and the underwater transducer 7 continues to drive the fish group to move to the water surface;
[0048] (3) When the information fed back by the underwater camera 6 estimates that the fish population in the water layer where the fishing net is located is insufficient, the underwater transducer 7 is continuously moved to the water surface to increase the fish population density on the water surface. When the information fed back by the underwater camera 6 estimates that the fish population in the water layer where the fishing net is located is too much, the fish population can move to the water layer below through the area by closing part or all of the underwater transducer 7, so as to prevent the number of fish caught by the single drag net from being too much and causing damage to the fish body.
