Description

TECHNICAL FIELD

[0001] The present application relates to the field of deep sea aquaculture, in particular to a semi-submersible deep sea aquaculture net cage. BACKGROUND

[0002] At present, the net cover of the aquaculture net cage is mostly gravity type, that is, the upper end of the net cover is hung on the floating body, and the lower end is connected with the heavy weight or structure by using the traction rope. The net cover of this type will be deformed greatly with the increase of flow rate and wave, which will affect the water volume and the swimming range of the cultured fish, and the repeated movement in the sea water will also affect the service life of the net cover. Moreover, due to the poor environment of the sea area where the net cage is located, the wind, wave and flow are large, and the deep sea aquaculture net cage has many structural components, so the movement of the net cover under the action of wind, wave and flow is increased, which tests the service life of the net cover. During the movement of the net cover, the repeated friction with the structural components greatly reduces the service life of the net cover.

[0003] In addition, under the action of wind and wave, the netting is always in the process of swinging and shaking, and the fatigue damage of the connection between the netting and the structure is large. The netting and the netting often break at this position. The extension amount of the polymer net cover is more than 6%, so after being bound on the large size component, the net cover is always in a relaxed state, and it is easy to collide with other components during the swinging process of the net cover, which leads to abnormal wear of the net cover. If the damage of the net cover is not found in time, the cultured fish will run out from the damaged part, causing certain economic loss. SUMMARY

[0037] The binding line 90 includes a binding rod binding line 96 for binding the net sheet 80 to the binding rod 70.

[0038] The binding rod 70 is arranged on the outer side wall of the structural frame 20 and is arranged on the inner side of the outer side wall relative to the ear plate 40.

[0044] The semi-submersible deep-sea aquaculture net cage 100 of the application, the vertical net is the side net of the net cage, and the horizontal net is the bottom net. The form of the bottom net can be consistent with the vertical net, and the side net can be composed of the net cage units 102 connected in sequence. The bottom net can also be composed of the net cage units 102. Adjacent net cage units can share part of the structural frame.

[0045] The application is mainly applied to a frame type deep-sea aquaculture net cage. The tensioning type net hanging method is to hang the net in a tensioning form on the structural frame, so as to avoid the friction of the net cable and the damage of the net.

[0046] The structural frame 20 of the present application comprises a top structural frame 22, a left structural frame 26, a right structural frame 28, and a bottom structural frame 24.

[0047] The structural frame 20 is evenly distributed with the perforated ear plates 40, and the binding rods 74 and the binding rod bases 30 are welded around the structural frame 20. The binding rods 74 can be made of round steel binding rods. The binding rod bases 30 are made of round steel bases.

[0048] The structural frame 20 is welded by the top structural frame 22, the left structural frame 26, the right structural frame 28, and the bottom structural frame 24. The top structural frame 22, the left structural frame 26, the right structural frame 28, and the bottom structural frame 24 can be round pipes, square pipes, rectangular pipes, or box-shaped structures. The formed frame can be square, rectangular, regular polygon, or irregular polygon.

[0049] The structural frame 20 is evenly distributed with the perforated ear plates 40, and the perforated ear plates 40 are arranged and designed to be consistent with the positions of the horizontal net cords 62 and the vertical net cords 64 of the netting. Moreover, the perforated ear plates 40 on the top structural frame 22 and the bottom structural frame 24 correspond to each other, and the perforated ear plates 40 on the left structural frame 26 and the right structural frame 28 are similar. The directions of the perforated ear plates 40 are consistent with the directions of the horizontal net cords 62 and the vertical net cords 64.

[0050] The binding rods 70 and the binding rod bases 30 are installed on the inner side or the outer side of the perforated ear plates 40, and the distance between the installation and the perforated ear plates 40 is basically consistent with the distance between the vertical net cords 64 or the horizontal net cords 62 and the ear plates 40, so as to ensure that the net sheet 80 has a certain distance with the ear plates 40 after installation, and prevent the net sheet 80 from being damaged by rubbing with the ear plates.

[0051] The round steel structure of the binding rod 70 forms a continuous and closed loop structure, and the binding rod base 30 is evenly distributed between the binding rod 70 and the top structural frame 22, the left structural frame 26, the right structural frame 28, and the bottom structural frame 24.

[0052] The netting is made of the net sheet 80 and the horizontal net cords 62 and the vertical net cords 64 which are bound by the binding wire 90.

[0053] The end of the horizontal net cord 62 or the vertical net cord 64 is inserted and knitted with the lifting ring 602, and the lifting ring 602 is inserted into the lifting ring sheath 603 in advance before being inserted and knitted, so as to prevent the lifting ring 602 from being damaged by directly rubbing with the bolt after being tensioned.

[0054] The length of the vertical net cord 64 is determined by the near-net-cord end bolt hole of the perforated ear plate 40 installed on the top structural frame 22 and the bottom structural frame 24 at both ends. In order to ensure tensioning, the length of the vertical net cord 64 is determined according to the relationship between the net cord elongation and the tension value.

[0055] The length of the horizontal cable 62 is determined by the bolt holes of the perforated lug 40 installed on the left and right structural frames 26 and 28 at the near cable end. To ensure tension, the length of the horizontal cable 62 is determined according to the relationship between the elongation of the cable and the tension value, and the length of the horizontal cable 62 is determined according to the determined tension value.

[0056] As shown in Figure 7 For example, the maximum elongation of the cable is 6% according to the elongation curve of the Φ18 ultra-high molecular weight polyethylene rope. The maximum elongation basically reaches the maximum breaking load. The greater the tension value, the greater the elongation. If the distance between the left and right vertical lug plates 44 is 10 m, the preset tension value is 14.15 KN, which is determined by experiment. Take 10,000 mm of cable, and pre-tension. When the tension reaches 14.15 KN, record the actual cable length of 10,200 mm, and the elongation rate is 2%. Therefore, the length of the 10 m cable should be 9.8039 m minus the elongation rate.

[0057] The horizontal cable is similar to the vertical cable. Table 1 shows the experimental results of the elongation rate under a certain load.

[0058] Table 1

[0059]

[0060] The edge cable of the vertical cable 64 is inside the insertion and weaving position of the horizontal cable 62. The vertical cable 64 is evenly distributed according to the mesh density and stress condition except for the edge cable.

[0061] The edge cable of the horizontal cable 62 should be inside the insertion and weaving position of the horizontal cable 62. The horizontal cable 62 is evenly distributed according to the mesh density and stress condition except for the edge cable.

[0062] The horizontal binding line 92 and the vertical binding line 94 are bound within the range of the edge cable of the vertical cable 64 and the horizontal cable 62.

[0063] The net is connected to the structural frame 20. When the net made of the mesh 80 and the horizontal cable 62 and the vertical cable 64 bound by the horizontal binding line 92 and the vertical binding line 94 is installed, the lifting ring 602 should be installed first, and the lifting ring 602 is connected to the perforated lug 40 by using bolts, nuts and gaskets. The perforated lug 40 uses the bolt hole at the near cable end, and the bolt hole at the near structural frame end is used as a backup. When the cable is stretched for a long time, the backup is used.

[0064] The mesh 80 is bound with the vertical cable 64 and the horizontal cable 62. The edge of the remaining mesh 80 that is not bound with the vertical cable 64 and the horizontal cable 62 is bound and connected to the binding rod 70 by using the binding rod binding line 96.

[0065] The hanging net mode of the tension type deep sea culture net cage of the application can make the net cord tensioned between structures, the net piece 80 is sewn on the net cord 60, the formed net cover is not easy to swing with wind and wave flow, the friction with the structure is reduced, and the collision and friction with other accessory structures or components are also reduced, so that the service life of the net cover is effectively improved.
