Problems solved by technology

[0004] Because super-large ponds are more seriously affected by wind and waves, the bacterial film on the surface often gathers on the leeward side of super-large ponds, resulting in poor water quality. Therefore, the remains of dead animals are often seen here, which exacerbates the deterioration of water quality in local waters. and thus affect the overall farming results
Especially after the low air pressure, under the action of level 8 or above for more than 2 hours, most of the jellyfish are likely to concentrate in the leeward, squeeze each other, and lose their mobility, resulting in a large area of ​​death

Embodiment 1

[0021] 1. Construction of the unit device

[0022] The unit device is composed of fixed pile 1, pile cable 2, floating ball 4, strip curtain 6, cable 5 and other structures. The cables run perpendicular to the direction of wind and waves common to the pond. The cable is connected with the pile cable, and the pile cable 2 forms an angle of 120° with the cable 5, and the fixed floating ball 3 is suspended at the joint. And according to water depth, keep cable length constant, adjust the length of pile cable 2, make cable 5 be in tight state. A strip curtain 6 is hung on the cable 5. The width of the strip curtain 6 is 0.2 meters and the length is 2-3 meters; a falling stone 7 is hung below the strip curtain to prevent the strip curtains from floating and entangled with each other, and form a top-down wave-dissipating curtain. Floats are attached directly to the cable, and the number is increased or decreased to keep the cable above the water.

Embodiment 2

[0030] 1. The construction of the unit device, the same as above

[0031] In the breeding base of Dalian Yulong Seafood Breeding Co., Ltd. located in Chengziyuan District, Dalian City, the outer pond of the breeding base is trapezoidal, with an upper base of 1696 meters, a lower base of 1520 meters, a height of 1123 meters, and a total of 2707 mu of 180.6 hectares. The average water depth is 2.7 meters, and sea cucumbers are cultivated on the outside of the above pond and at the bottom.

[0032] 2. The construction of Xiaolang monomer is the same as above

[0033] 3. Arrangement of wave dissipation device

[0034] Along the two ends in the north-south direction, leave about 150 meters free, and set up two wave-dissipating devices in the east-west direction, docking, see Figure 4 . Same as above, set up 7 rows and 14 wave-dissipating devices in the north-south direction (in Figure 4 Only 5 rows are shown in the middle), and 8 rows and 16 wave-dissipating devices are set i...

Abstract

The invention aims to provide a wave-attenuating device for extra-large pond culture so as to remedy the defects in the prior art. The wave-attenuating device provided by the invention is composed of a plurality of unit devices, wherein each of the unit devices comprises a cable rope, a strip curtain suspended on the cable rope and a pile cable for fixing the cable rope; a counterweight is suspended below the strip curtain; and a floating ball is mounted on the cable rope. A dynamic enclosure formed by the wave-attenuating device provided by the invention becomes good supplement of dissolved oxygen, thereby remedying the deficiency of dissolved oxygen which may happen after wave attenuation. Joint is formed between the water surface and the underwater, so that generation of an upwelling current is facilitated, and anaerobic condition is prevented. Therefore, the efficiency and benefit can be remarkably improved, and the device is convenient to operate and suitable for being widely applied in farms.

Description

technical field [0001] The invention belongs to the technical field of aquaculture devices, and in particular relates to a wave-elimination device for super-large pond cultivation. Background technique [0002] When wild sea cucumbers and other economic animals grow in natural sea areas, due to the influence of wind, waves and tidal currents, sea cucumber aquatic products often seek shelter from waves, so they are more common in the crevices of rocks and reefs, making it difficult to harvest and feed. The feed factor is low and the growth rate is low. Sea cucumbers cultured in small ponds have clear activity boundaries and are easy to harvest, but due to the small water body, the water quality changes greatly during the culture period and the mortality rate is high. Therefore, aquaculture practitioners have been researching various specific breeding methods, such as the invention patent "A Sea Cucumber Breeding Method" with the publication number CN102077801A, which disclos...
