Embodiment 1

[0021] A marine ranching device for deep-sea farming areas, comprising a rectangular floating block 1, positioning piles 2 are welded at the four corners of the bottom of the floating block 1, anchor blocks 3 are fixedly connected to the ends of the positioning piles 2, and netting is arranged between the positioning piles 2 Box 4, a lead screw 2a is arranged in the positioning pile 2, a motor 2b is fixedly connected to the top of the positioning pile 2, the motor 2b is located in the floating block 1, the lead screw 2a is connected with the motor 2b, and a motor 2b is arranged between two adjacent positioning piles 2 Fixed frame 5, fixed frame 5 is positioned at the outside of net cage 4 and has no contact, is welded with several fixed blocks 5a on the fixed frame 5, and fixed block 5a is sleeved with bearing 5b, and bearing 5b inner ring is connected with rotating shaft 6, and on rotating shaft 6 Several arc-shaped plates 7 are provided. The positioning pile 2 can support th...

Embodiment 2

[0030] The positioning pile 2 is welded under the floating block 1. The positioning pile 2 and the anchor block 3 can position the marine ranch device. The cage 4 is between the positioning piles 2. The motor 2b in the floating block 1 drives the screw 2a to move up and down. , lead screw 2a drives net cage 4 to move up and down, similarly, fixed frame 5 also can move up and down, when the ocean current of sea bottom is bigger, can move fixed frame 5 to be flush with net cage 4, utilize arc plate 7 to Resist the impact of ocean currents. In this embodiment, there are four arc-shaped plates 7 to protect the net cage 4 and the safety of breeding. When the ocean current on the seabed is too large, the net cage 4 can be lifted to the shallow sea where the ocean current is small to avoid the ocean current. impact, and the wind power generation device 17 and solar panel 14 above the buoyant block 1 can provide energy for the marine ranching device, and the helicopter landing field ca...

Embodiment 3

[0032] In order to ensure the feasibility of this experiment and avoid the influence of factors such as bad weather on the ocean, this experimental model is carried out in the experimental still water pool. This experiment uses a trailer drag model to simulate the relative movement between seawater and marine pastures. When the shaped plate 7 was 1.1rad, the speed dragged by the trailer was set to 1m / s uniform motion, and a flow meter was housed in the net cage 4. At this moment, the flow meter would record the flow velocity in the net cage 4. After the numerical value was measured, the The arc plate 7 is respectively set to 1.2rad, 1.3rad, 1.4rad, 1.5rad to repeat the above experiment to obtain the first set of data,

[0033] When the trailer speed is 1.2m / s, repeat the above experiment to get the second set of experimental data,

[0034] When the trailer speed is 1.4m / s, repeat the above experiment to obtain the third set of experimental data; the experimental results are at...

Abstract

The invention relates to the field of deep sea culture, in particular to a marine ranching device used in a deep sea culture area. The marine ranching device used in the deep sea culture area comprises a rectangular floating block, gauge piles are welded to the four corners on the bottom of the floating block, the tail ends of the gauge piles are fixedly connected with anchor blocks, a cage is arranged among the gauge piles, and screw rods are arranged in the gauge piles. Motors are fixedly connected with the tops of the gauge piles, the motors are located in the floating blocks, the screw rods are connected with the motors, a fixing frame is arranged between every two adjacent gauge piles, the fixing frames are arranged outside the cage and make no contact with the cage, a plurality of fixing blocks are welded to the fixing frame, bearings sleeve the fixing blocks, rotary shafts are connected with inner rings of the bearings, and a plurality of arc-shaped plates are arranged on the rotary shafts. By means of the marine ranching device, the problems in the prior art are solved that the cage volume loss rate is high, the breeding efficiency is low and the breeding environment is poor.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture, in particular to a marine pasture device for deep-sea aquaculture areas. Background technique [0002] Driven by the social economy and the development of the tourism industry, my country's recreational fishery has developed rapidly. Whether it is from the perspective of economic or social benefits, it has good development prospects and great development potential. Therefore, recreational fishery has a broad space for development. Potential guide, actively guide tourists to participate in recreational fishing activities. Moreover, with the large amount of fishing in the offshore area, the number of fish in the offshore area has decreased greatly, and deep-sea aquaculture is particularly important. At present, the area of ​​mariculture in my country is about 30 million mu, accounting for only about 15% of the usable area of ​​shallow tidal flats. The utilization space and potential of tidal flat...
