Description
Technical Field
The utility model relates to a flexible purse net cultivation device, and mainly relates to the fields of maritime purse net cultivation, shrimps and the like.
Background
Mariculture, i.e. a method of using a seine suspended in water to form a semi-closed seine with an open top, in which fish, shrimp, etc. are cultivated. At present, the technology used for purse net cultivation has a square or round floating frame for providing buoyancy, and anchor chains are arranged inside and outside the floating frame so as to enable the floating frame to keep shape and be relatively fixed in a water area, and the purse net is connected with the floating frame and is of an open structure with bottom and surrounding meshes. The outer anchor chain of the floating frame is often connected with the anchor pile. The lower end of the anchor pile is inserted into the mud layer. In the prior art, the floating frame is often in an integral hard connection structure, for example, hard pipes which are integrally formed by splicing sections, the spliced parts are often in fixed connection, and therefore, under the extreme conditions of typhoons and the like, the floating frame is easy to locally damage due to relative displacement, and therefore, the purse net is likely to break. In addition, in the prior art, outer anchor chain one end links to each other with the floating frame, and the anchor pile is directly connected to the other end, and when the bad weather is encountered like this, the circumstances that the anchor chain will float the frame and draw apart probably appears in the quick travel of floating frame.
Disclosure of Invention

One end of the floating frame centripetal connecting rope is connected with the spherical floating frame unit, and the other end of the floating frame centripetal connecting rope is mutually connected with the center of the circular floating frame, namely the floating frame centripetal connecting ropes are distributed in a central symmetry manner; the purse net is of an open structure, namely, the purse net is provided with a side face and a bottom, the upper end of the purse net is connected with each spherical floating frame unit, and the lower end of the purse net is connected with the purse net annular counterweight, so that the purse net has tension for keeping the annular open structure. The upper ends of the floating frame longitudinal connecting ropes are connected with spherical floating frame units, and the lower ends of the floating frame longitudinal connecting ropes are connected with buffer balancing weights. The upper end of the second longitudinal connecting rope is connected with the buffer balancing weight, and the lower end of the second longitudinal connecting rope is connected with the anchor chain system so as to be fixed. Preferably, the anchor chain system is provided with a ring-shaped stay rope, a bottom anchor chain and an anchor pile, the lower end of the second longitudinal connecting rope is connected with the ring-shaped stay rope, the bottom anchor chain is connected with the ring-shaped stay rope, and the connecting point of the bottom anchor chain and the connecting point of the second longitudinal connecting rope and the ring-shaped stay rope are staggered. The outer end of the bottom anchor chain is connected with an anchor pile, and the anchor pile is inserted into the mudstone layer to be kept fixed. Preferably, the anchor chain system is only an anchor pile.
The purse net ring-shaped counterweight is provided with the counterweight continuously or intermittently around, and the tension of the ring-shaped open structure can be maintained because the diameter of the opening of the purse net is larger than that of the bottom.
Further, the included angle between the floating frame longitudinal connecting rope and the second longitudinal connecting rope is smaller than 180 degrees, and the buffer balancing weight plays a role in tensioning. When the tension force is increased due to external impact, the included angle between the floating frame longitudinal connecting rope and the second longitudinal connecting rope is automatically increased, so that the tension force is reduced.
Preferably, the spherical floating frame unit of the device is provided with two circles of concentric circles, and the top of the spherical floating frame unit is also provided with a working platform, an inner ring railing and an outer ring railing. The bottom of the working platform is fixed with the top of the spherical floating frame unit, and the spherical floating frame unit forms a two-circle concentric circle structure, so that the working platform can be supported to prevent rollover. The working platform provides the work support requirements of feeding, catching and the like for workers. Further, the working platform, the inner ring railing and the outer ring railing all adopt multi-section combined structures, so that damage caused by severe weather is avoided.
The utility model has the beneficial effects that each spherical floating frame unit has a spherical structure, high overall stability and strong impact resistance, and when the spherical floating frame units shake in sea water, the spherical floating frame units have no sharp corners, so that the problem of stress concentration is avoided when the spherical floating frame units collide with each other, and the force is easier to unload. The cooperation of each floating frame centripetal connecting rope and the floating frame transverse connecting rope ensures that the whole stress is balanced. The combination of the floating frame longitudinal connecting ropes, the buffer balancing weights and the second longitudinal connecting ropes provides flexible stretching, so that reliability is improved. The bottom anchor chain is connected with the annular pull rope, and the connecting points of the bottom anchor chain and the second longitudinal connecting rope are staggered with the connecting points of the annular pull rope, so that a flexible stretching effect is further provided. Thereby the reliability of the whole device in severe environment is obviously enhanced.
