[0003] Although the current squid artificial spawning collection device can be used as a squid spawning attachment to expand the area of the spawning field; but when collecting eggs, the artificial spawning collection device needs to be lifted by a rope, which is inconvenient to operate, and the artificial spawning collection During the rising process of the device, it is impacted by sea water, and it is easy to cause the attached eggs attached to the artificial spawning collection device to fall off and lose

Embodiment Construction
[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0029] Such as figure 1 As shown, a vertical lifting anti-shed squid spawning collection device includes: a lowering rope, a support frame, an egg attachment device 3, a floating protection device 2, and a trigger release mechanism 4.
[0030] The support frame includes four vertical support rods 1, and the four vertical support rods are distributed at the four apex positions of the rectangle. The outer surface of the vertical support rod is provided with a lower limit block 1.1 of the support rod, a middle limit block 1.2 of the support rod and an upper limit block 1.3 of the support rod. The lower limit block of the support rod, the middle limit block of the support rod and the upper limit block of the support rod are distributed sequentially from bottom to top. The lower limit block of the support rod is located at the bottom of the vertica...

The invention discloses a vertical lifting anti-drop squid spawning collection device, and aims to provide a squid spawning collection device which is convenient in egg taking operation and effectively avoids the problem of drop loss of eggs attached onto an egg attaching device due to seawater impact in the rising process of the egg attaching device. The squid spawning collection device comprises a supporting frame, the egg attaching device and a floating protection device, the supporting frame comprises a plurality of vertical supporting rods, the egg attaching device comprises a lifting flat plate, an auxiliary floating block, a lower supporting flat plate, a connecting vertical rod and a plurality of egg attaching ropes, the lifting flat plate can slide along the vertical supporting rods, the auxiliary floating block is arranged on the upper surface of the lifting flat plate, the lower supporting flat plate is positioned above the lifting flat plate, the lifting flat plate is connected with the lower supporting flat plate through the connecting vertical rods, and the egg attaching ropes are arranged between the lifting flat plate and the lower supporting flat plate. The floating protection device comprises a floating frame, a protection box, a main floating block and a trigger release mechanism, wherein the floating frame can slide along the vertical supporting rods, the protection box is arranged on the floating frame, and the main floating block is arranged on the outer side face of the protection box.
Description
technical field [0001] The invention relates to a squid spawning collection device, in particular to a vertical lifting type anti-shedding squid spawning collection device. Background technique [0002] The range of squid spawning habitat is very narrow, and squid spawning has high requirements for attachments. The squid spawning attachments in natural sea areas are mainly corals, large seaweeds, and artificial debris, of which corals account for more than 60% and artificial debris It accounts for about 30%, and the base of seaweed accounts for about 10%. However, with the destruction of the marine environment, the resources of spawning attachments in natural sea areas, mainly gorgonians, have been severely damaged, the number has dropped sharply, and the area of traditional spawning grounds has plummeted ; Thereby putting artificial spawning attachments is widely used as a supplementary means in the squid resource multiplication process. [0003] Although the current squ...
