The netting fixing device embedded in the circular floating net cage will be further described and explained below.
The structure of the netting fixing device comprises:
the arc-shaped metal rod 4 is an arc-shaped metal round rod with two ends provided with connecting plates 5 and a middle inner side provided with a lantern ring 6, has high strength and rigidity, and can bear large load without buckling and deformation.
Connecting plates 5 at two ends of the arc-shaped metal rod 4 are welded on the inner side of the arc-shaped metal rod 4, the number of bolt holes 7 in the connecting plates 5 is not less than 2, the bolt holes 7 are in a long strip shape, the length of the bolt holes 7 is not less than 3 times of the diameter of the bolts 8, the width of the bolt holes 7 is not less than 1.5 times of the diameter of the bolts 8, the length direction of the bolt holes 7 is arranged along the circumferential direction of the arc-shaped metal rod 4, and the width direction of the bolt holes 7 is arranged along the radial. Fig. 2 and 3 show a schematic structural view of the connecting plate 5 with 2 bolt holes 7.
The arc metal rods 4 can be connected end to form a closed circular ring based on bolt holes 7 in the corresponding connecting plates 5 fixed by bolts 8, and the number of the arc metal rods 4 required for assembling the circular ring is not less than 3. The connecting plate 5 and the lantern ring 6 are both positioned on the inner side of the arc-shaped metal rod 4, and the annular arc-shaped metal rod 4 is assembled in a smooth and continuous distribution mode on the outer side, so that the arc-shaped metal rod is convenient to use as shown in figures 3-5. The outside and the net cage netting contact of the circular ring form arc metal rod 4, and smooth continuous distribution's the arc metal rod 4 outside can not take place to entangle with the net cage and drag, makes things convenient for reciprocating of net cage fixing device when inside installs additional.
Fig. 5 shows a structural schematic diagram that the arc-shaped metal rods 4 have a sector radian of 90 degrees, and 4 arc-shaped metal rods 4 are mutually assembled into a closed circular ring shape. The fan-shaped arc degree value of the arc-shaped metal rods 4 can also take other numerical values as long as a plurality of arc-shaped metal rods 4 can be mutually assembled into a closed circular ring. Each arc-shaped metal rod 4 is at least provided with a lantern ring 6, one lantern ring 6 corresponds to one steel wire rope 9, so the number of the arc-shaped metal rods 4 required for assembling into a circular ring shape is not less than 3, and each circular ring-shaped arc-shaped metal rod 4 can be kept balanced and stable under the fixing action of at least 3 steel wire ropes 9.
The sleeve 10 is a straight pipe made of metal or plastic, the inner diameter of the sleeve 10 is not less than 3 times of the outer diameter of the steel wire rope 9, the outer diameter of the sleeve 10 is greater than the outer diameter of the lantern ring 6, and the diameter of a hole of the lantern ring 6 is not less than 2 times of the outer diameter of the steel wire rope 9. Generally, the length of the sleeve 10 may be determined based on the approximate average of the mesh depth divided into multiple equal parts, such as the length of the sleeve 10 of FIG. 9 at approximately 1/4 of the mesh depth.
The function of the sleeve 10 is: 1. the relative position of the adjacent circular arc-shaped metal rods 4 is restrained and controlled, so that the position of each circular arc-shaped metal rod 4 clinging to the netting is basically fixed; 2. the netting inclines when being impacted by ocean current, the inclination of the netting enables the netting to be collided with the netting fixing device inside the netting fixing device necessarily, the steel wire ropes 9 on the netting fixing device incline synchronously, the sleeve 10 sleeved on the steel wire ropes 9 restrains and controls the inclination amplitude of the flexible steel wire ropes 9, the inclination slopes of the steel wire ropes 9 inside the sleeve 10 are the same up and down, namely the periphery of the netting is restrained to generate approximately the same inclination slope in the same direction, the netting is difficult to gather under the restraining and restraining of the sleeve 10 and the arc-shaped metal rod 4, and therefore the volume ratio of the netting is maintained to the maximum extent.
The number of the circular arc-shaped metal rods 4 shared by the netting fixing device is not less than 2, and as shown in fig. 9, the structural schematic diagram of the circular arc-shaped metal rods 4 shared by 4 is shown.
The outer diameter of the arc-shaped metal rod 4 is slightly smaller than the smaller of the diameter of the netting 2 and the inner diameter of the floating pipe in the net cage frame 1, so that the arc-shaped metal rod 4 assembled into a circular ring shape can sink from the upper part of the net cage and is embedded into the net cage. Generally, the inner diameter of the inner floating pipe is the maximum diameter of the internal space of the net cage frame 1, and the inner diameter of the inner floating pipe of the net cage frame 1 and the diameter of the net coat 2 are both larger than the outer diameter of the circular arc-shaped metal rod 4, so that the net cage frame 1 and the net coat 2 cannot prevent the net coat fixing device from being embedded. Certainly, the outer diameter of the circular arc-shaped metal rod 4 cannot be too small, and the arc-shaped metal rod 4 is difficult to contact and hold the netting due to the too small outer diameter, so that the function of maintaining the volume ratio of the net cage is reduced.
The lifting netting fixing device is simple in structure, light in weight, few in material consumption, high in strength, low in overall price, suitable for netting reinforcement of the existing circular floating net cage, and economical and practical.
Secondly, installation of the netting fixing device:
firstly, the length of the sleeve 10, the sector radian of the arc-shaped metal rods 4, the number of the circular arc-shaped metal rods 4 and the like are designed according to the depth and the diameter of the net cage netting 2, and then accessories are processed for later use.
The installation process of the netting fixing device is as follows: firstly, all the arc-shaped metal rods 4 are mutually assembled into a circular shape, a steel wire rope 9 is respectively moored and bound on each lantern ring 6 of one circular arc-shaped metal rod 4, then pulling the steel wire ropes 9 to immerse the circular arc-shaped metal rod 4 into the water body in the net cage, sleeving a sleeve 10 on each steel wire rope 9, then a second circular arc-shaped metal rod 4 is sleeved into each steel wire rope 9 based on the lantern ring 6 and then is sunk into the water, a sleeve 10 is sleeved on each steel wire rope 9, then a third circular arc-shaped metal rod 4 is sleeved into each steel wire rope 9 based on a lantern ring 6 and then is sunk into water, by analogy, a structure that the circular arc-shaped metal rods 4 and the sleeves 10 are alternately distributed on the steel wire ropes 9 is gradually formed, all the sleeves 10 and the circular arc-shaped metal rods 4 are sleeved, and then the steel wire ropes 9 are straightened and bound on the net cage frame 1.
In the design, after all the sleeves 10 and the circular arc-shaped metal rods 4 are sleeved, the length of the steel wire rope 9 is slightly smaller than the depth of the netting. Namely, after the device is arranged on the net cage frame 1, the annular arc-shaped metal rod 4 at the bottommost part needs to be away from the net bottom by a certain distance, and the annular arc-shaped metal rod 4 at the bottommost part cannot contact and press the net bottom. The weight of the lifted device is transferred to the net cage frame 1 through the steel wire rope 9, and the net 2 does not bear the weight of the lifted device.
Therefore, the connection method of the device is simple, underwater operation is not needed when the device is additionally arranged inside the net cage, and construction is simple and convenient. Fig. 4 to 9 show an assembly process of the netting fixing device, fig. 10 shows a schematic structural view of the net cage with the netting fixing device, and fig. 11 and 12 show detailed views of the netting fixing device embedded in the netting.
Thirdly, dismantling the netting fixing device:
when the operations such as netting replacement, net cage cleaning, cultured fish harvesting and the like are carried out, the netting fixing device additionally arranged in the net cage can be detached; after the operation is finished, the netting fixing device is additionally arranged inside the net cage.
The detaching process of the netting fixing device is as follows: the method comprises the steps of unfastening the steel wire ropes 9 bound on a net cage frame 1, drawing out and removing the sleeve pipes 10 sleeved on the steel wire ropes 9 at the uppermost parts, gradually drawing up the steel wire ropes 9, drawing out and removing the lantern rings 6 of the circular arc metal rods 4 from the steel wire ropes 9 when the first circular arc metal rod 4 is exposed out of water, finishing the dismantling work of the first circular arc metal rod 4, then continuing to draw out and remove the sleeve pipes 10 sleeved on the steel wire ropes 9, gradually drawing up the steel wire ropes 9, dismantling the second circular arc metal rod 4 in the same method, and so on until all components of the netting fixing device are lifted away from the water surface, and completing the dismantling.
Therefore, the dismounting method of the device is very simple, underwater operation is not needed, and construction is simple and convenient.
Different lengths of the sleeve 10 and different arc-shaped arcs of the arc-shaped metal rod 4 can be used according to actual needs, and several embodiments are described below.
Example 1: as shown in fig. 2 to 12, the connecting plates at the two ends of the arc-shaped metal rod 4 are provided with 2 bolt holes 7, and the middle part of the inner side of the arc-shaped metal rod 4 is welded with a lantern ring 6. The arc-shaped metal rods 4 have a sector radian of 90 degrees, and the 4 arc-shaped metal rods 4 are fixedly connected end to form a closed circular ring shape, as shown in fig. 5. The length of the sleeve 10 is about 1/4 of the depth of the netting, so the proposed device uses 16 curved metal rods 4, 16 sleeves 10 and 4 steel cables 9 in total, as shown in fig. 6.
