Description
Technical Field
The invention relates to a cuttlefish egg attaching device, in particular to a bottom sinking type cuttlefish egg attaching device.
Background
The cuttlefish spawning habitat range is narrow, the cuttlefish spawning requirement on attachments is high, the cuttlefish spawning attachments in natural sea areas mainly comprise coral, large seaweed and artificial residues 3, wherein the coral accounts for over 60 percent, the artificial residues accounts for about 30 percent, and the seaweed bases account for about 10 percent; however, with the damage of the marine environment, the egg attachment resource quantity mainly comprising the gorgonian in the natural sea area is seriously damaged, the quantity is sharply reduced, and the area of the traditional spawning site is sharply reduced; therefore, the artificial egg attachment is put into the cuttlefish culture medium and widely used as a supplementary means in the proliferation process of the cuttlefish resources. At present, natural cuttlefish egg attachments and artificially thrown cuttlefish egg attachments are generally fixed attachments or attachments capable of swinging left and right like seaweed, when cuttlefish lays eggs, a large number of cuttlefish eggs are generally accumulated at a certain position of the attachments, each string of cuttlefish eggs is too large, sometimes each string of cuttlefish eggs can reach more than 300 grains, and a large number of cuttlefish eggs are stacked together, so that a large number of cuttlefish eggs wrapped in the middle are delayed in development and even rotten and dead, the hatching rate is seriously reduced, and serious obstacles are caused to the propagation of cuttlefish resources in natural sea areas.
Disclosure of Invention
The invention aims to provide a bottom-sinking type cuttlefish egg attachment device which can effectively disperse cuttlefish eggs to avoid the problem that a large number of cuttlefish eggs wrapped in the middle are delayed in development, even rotten and dead and seriously reduced in hatching rate due to the fact that a large number of cuttlefish eggs are stacked together.
The technical scheme of the invention is as follows:
a bottom-sinking cuttlefish egg attaching device comprises a bottom frame and a lifting egg attaching device, wherein the bottom frame is sunk and supported on the surface of the sea bottom; the lifting type egg attaching device comprises a self-settling egg attaching structure, a first floating ball, a connecting rope and a guide wheel set, wherein the self-settling egg attaching structure comprises a second floating ball, a vertical guide rod arranged on the underframe, an upper limiting block and a lower limiting block which are arranged on the vertical guide rod, a sliding sleeve arranged on the vertical guide rod in a sliding mode, a balancing weight arranged on the sliding sleeve and an egg attaching rope connecting the sliding sleeve and the second floating ball, the sliding sleeve is arranged between the upper limiting block and the lower limiting block, and the buoyancy of the second floating ball is larger than the sum of the gravities of the egg attaching rope, the sliding sleeve and the balancing weight, so that the sliding sleeve slides upwards along the vertical guide rod and abuts against the upper limiting block under the buoyancy effect of the second floating ball; the first floating ball floats on the sea surface, the guide wheel group comprises a first guide wheel positioned below the vertical guide rod, the connecting rope is connected with the first floating ball and the sliding sleeve, the connecting rope bypasses the first guide wheel, the first floating ball fluctuates up and down under the action of sea waves, and when the first floating ball floats up under the action of sea waves, the first floating ball drives the sliding sleeve to slide down along the vertical guide rod through the connecting rope so that the egg-attached rope moves down together until the sliding sleeve abuts against the lower limiting block; when the first floating ball floats downwards under the action of sea waves, the second floating ball drives the egg-attaching rope and the sliding sleeve to move upwards together until the sliding sleeve abuts against the upper limiting block; when the cuttlefish attaches the ovum on attaching the ovum rope, along with the increase of the cuttlefish ovum on attaching the ovum rope, the gravity of effect on the second floater increases gradually, when the cuttlefish ovum on attaching the ovum rope, attach the ovum rope, the gravity sum of sliding sleeve and balancing weight is greater than the buoyancy of second floater, under the effect of balancing weight, the sliding sleeve will slide down along vertical guide arm, until the sliding sleeve supports on stopper down.
