Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an aquaculture cage and a buffer device for fixing and connecting the cage. Background Art

[0002] Huge cages are set up in the ocean, and then fish, shrimps and other marine organisms are cultured in the cages. This breeding technology has been widely promoted. The cages in the prior art are basically composed of a large number of trusses, which makes the structure of the entire cage complex and the amount of construction materials is large, resulting in high costs. In addition, the connections between the trusses are all rigidly connected, and the fixed connection equipment of the breeding cage is mainly connected by the cage body and several steel wire cables. Each steel wire cable is connected to the anchor pile for fixing, which makes the cage less adaptable and less capable of resisting wind and waves. It cannot withstand the impact of large waves. When there are large winds and waves, the cage will shake and collide as a whole, and the windward rope will break under the huge impact of the wind and waves, causing the cage to overturn and be damaged, squeezing the aquatic products, and seriously affecting the normal survival of the organisms in the cage. The damage to the cage causes the cultured aquatic products to be injured or even die or escape, causing economic losses to the farmers.

[0020] The aquaculture net cage 1 includes a net 11, which is a corrugated cylindrical shape, and the four corners of the net 11 are connected with ears 12, and the ears 12 are fixedly connected to the second connecting rope 5. The pleated shape of the net 11 can facilitate the lifting and deformation of the aquaculture net cage 1 in the water body, and each pleat at the four corners of the net 11 is provided with an ear 12, that is, the four corners of the net 11 can simultaneously pull multiple second connecting ropes 5 to shape the net 11, thereby preventing the net 11 from shaking with the water body and rubbing against the aquatic products in the water body.

[0021] The floating platform 2 includes four L-shaped steel frames 21, which are spliced ​​diagonally into a cross shape. A connecting hole 22 is opened in the middle of the steel frame 21, and a bolt 23 is fixedly installed inside the connecting hole 22. The bottom of the bolt 23 is connected to a cross-shaped floating plate 24, and the bottom of the bolt 23 is fixedly installed on the connecting frame 3. Both ends of the steel frame 21 are installed with a fixing sleeve 25, and a floating ball 26 is fixedly installed inside the fixing sleeve 25. The steel frame 21 floats on the water surface through the floating plate 24 and the floating ball 26, which is convenient for positioning and installing the aquaculture cage 1. The steel frame 21 is set on the water body, which is convenient for the staff to move. The steel frame 21 is connected to the connecting frame 3 by bolts 23. When the wind and waves are strong, the bolts 23 come out from the inside of the connecting frame 3, causing the connecting frame 3 to lose the fixation of the floating platform 2. The connecting frame 3 and the aquaculture cage 1 sink to the seabed and are only softly connected to the steel frame 21 by ropes 38, so that the aquaculture cage 1 avoids the wind and waves on the sea surface, ensures the integrity of the aquaculture cage 1 and the aquatic products inside, and reduces the losses of the farmers. The upper end of the rope 38 can be connected and fixed by a winch to control the sinking distance of the aquaculture cage 1, and is also convenient for pulling the aquaculture cage 1 up again later.

The connecting rods 31 and the aquaculture net box 1 are woven and fixed into one. The upper end of the connecting rod 31 is fixed to the first folding rod 32 and the second folding rod 33 by a screw 34. The second folding rod 33 and the first folding rod 32 are connected to the first connecting block 37 and the first connecting block 36 through the second connecting block 37, so that when the second connecting block 37 is pulled by the rope 38, it will drag the first folding rod 32 and the second folding rod 33 to bend along the first connecting block 36 and the second connecting block 37, and finally close in a cross shape to seal the upper port of the aquaculture net box 1, so as to prevent the aquatic products from escaping from the top opening when the aquaculture net box 1 sinks to the bottom of the water body and floats with the waves, thereby reducing the losses of the farmers.

[0023] The guide plate 39 includes a main plate 391, the upper end of which is fixedly connected with four guide rollers 392, and the middle of the main plate 391 is provided with four vertical positioning holes 393, which are threadedly connected with the bolts 23.

[0024] A fixed connection buffer device is applied to an aquaculture cage, comprising a connection buffer mechanism 6, the connection buffer mechanism 6 comprising a rope ring 61 and a fixed plate 65, the bottom end of the rope ring 61 is fixedly connected to a guide rod 62, the upper end of the fixed plate 65 is connected to a sleeve 64, the bottom end of the guide rod 62 is fixedly connected to a piston disc 63, the piston disc 63 is slidably installed inside the sleeve 64, and a plurality of buffer components 66 are also sleeved and installed on the guide rod 62, the buffer component 66 is installed inside the sleeve 64 near one side of the rope ring 61 and in the middle of the piston disc 63; the number of the buffer components 66 is not less than four; the buffer component 66 comprises a first connecting piece 661 and a second connecting piece 662, and a spring 6 is fixedly connected between the first connecting piece 661 and the second connecting piece 662 63, the first connecting piece 661, the second connecting piece 662 and the spring 663 are all sleeved on the cylindrical surface of the guide rod 62, the first connecting piece 661 is connected to four first connecting rods 664, the second connecting piece 662 is connected to four second connecting rods 665, the other end of the first connecting rod 664 is hinged to the other end of the second connecting rod 665, and the fixed connection buffer device is installed on the bottom circle and the upper end of the aquaculture cage. By arranging a plurality of compressible and deformable buffer components 66 between the sleeve 64 and the piston disc 63, when the first connecting rope 4 or the second connecting rope 5 connected to the connecting buffer mechanism 6 is subjected to large wind and waves, the few cables facing the wind direction can buffer the impact force through the deformation of the buffer component 66 to prevent the cables from being broken.

[0025] Specifically, when the aquaculture net cage and the buffer device for fixed connection are used: the four corners of the bottom end of the aquaculture net cage 1 are tightened with the second connecting rope 5 to shape the aquaculture net cage 1, and a foldable connecting frame 3 is fixedly installed at the upper port of the aquaculture net cage 1. The connecting frame 3 and the floating platform 2 are connected by a rope 38, and the rope 38 is wound and fixed on the floating platform 2 by a winch. The other end of the second connecting block 37 is connected to the first connecting rope 4, and the first connecting rope 4 bypasses the end of the floating platform 2 and is fixed to the bottom of the water body. The middle of the first connecting rope 4 and the second connecting rope 5 are both buffered by the connecting buffer mechanism 6. If the first connecting rope 4 connected to the upper end of the aquaculture net cage 1 is subjected to When the impact force breaks, the aquaculture cage 1 will lose its upward pull and sink to the seabed as a whole. At this time, the descending rope 38 of the aquaculture cage 1 will tighten the second connecting block 37 inward, and the first folding rod 32 and the second folding rod 33 will be closed. The upper end opening of the aquaculture cage 1 is closed and sinks to the seabed, separating from the wind and waves on the sea surface, thereby avoiding damage to the aquaculture cage and the escape of farmed fish, reducing losses in the aquaculture industry. After the wind and waves, the rope 38 is pulled up again by the winch, and the aquaculture cage 1 is positioned and the first connecting rope 4 is re-fixed to complete the repair of the aquaculture cage 1.
