Description
Technical field
The utility model relates to a kind of fish population and strengthens the integrated ship of mark, relates in particular to the cuttlefish population and strengthens releasing ship.
Background technology
The Sepiella maindroni growth is fast, and life cycle short (life in 1 year), resource are replenished and recovered fast, are ideal marine life enhancement species.Along Zhejiang Coast is the main areal area of Sepiella maindroni, and the spawning ground is near Shengsi, Putuo, Xiangshan, Jiangjiang, island, east, Dongtou, and the wintering ground is in off-lying sea, the middle and south, Zhejiang.Long-term res shows, cuttlefish resource magnitude of recruitment then is closely related with the resource situation of next year.The reason that leads to the Sepiella maindroni resource exhaustion is mainly that fishing intensity is excessive.At present cuttlefish cage, cuttlefish trawlnet, cuttlefish plate once waited and specially catch work and already do not exist, throw the net, trawlnet, purse seine etc. are double catches also corresponding minimizing of operation, " the fishing for chain " that affects the Sepiella maindroni resource is progressively lax, and the Sepiella maindroni that can be enhancement releasing obtains the fully chance of rehabilitation.Through investigation, the Sepiella maindroni spawning ground attachment gorgonian of laying eggs, resource quantity also is tending towards recovering.Prior art is many improves by the damage that reduces the fingerling of releasing the effect of releasing, as Chinese invention patent " marine continuous enhancement releasing device ", the patent No. 200910194494.0 discloses a kind of marine continuous enhancement releasing device, is positioned on deck in ship structure and works.It comprises that the casing of releasing, antinose-dive leg, coolant inlet pipe, pin dish, the chute of releasing, butterfly valve, chute supported seat form.the casing of releasing is positioned on circular support, be used for placing the fry that to release, the bottom half of releasing is designed with apopore, be connected with chute by seal ring, fry is released to water body by chute, coolant inlet pipe is fixed on small arc-shaped on antinose-dive leg, chute divides, gliding groove two parts, upper hopper chute is connected with seal ring by locating dowel pin with the casing of releasing, gliding groove is released fry to water body, on, be connected by butterfly valve between gliding groove, chute is fixed by the chute supported seat, the valve of twitching in butterfly valve when releasing operation can be released, antinose-dive leg and supporting seat bottom all is connected with the pin dish, be convenient to regulate arbitrarily height according to the height of hull.Yet, the natural enemy of realm of nature cuttlefish is more, due to the predation of natural enemy, greatly reduce the survivor's rate of the population of releasing, therefore after the fingerling entry, need to manage the strengthened artificial population to accelerate the flouring of Artificial Population, improve enhancement effect, a whole set of carries out the equipment of specific reinforcement mark fast quick-recovery fishery resources, and matching design soon, and adaptive corresponding ship, fast breeding and the population being convenient to carry out in the target marine site cuttlefish are strengthened.
Summary of the invention
The purpose of this utility model is a kind of novel structure, the interior predator fish mark in the directed removing of energy Fast Calibration zone to be provided, to be applicable to the cuttlefish population reinforcement releasing ship that scale is released, kind of group energy carried out fast breeding and reinforcement for prior art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the cuttlefish population is strengthened releasing ship, comprise that the side is equipped with the hull of the controlled pipeline of releasing, wherein: the controlled pipeline top of releasing is attached with cuttlefish releasing population intensifying device and demarcates conveyor line; Cuttlefish releasing population intensifying device is demarcated conveyor line and is comprised the demarcation annular groove that caliberating device is installed; Caliberating device contains cantilever, and the cantilever near middle is provided with slip pipe; The end of cantilever is equipped with can release the population intensifying device propelling movement hammer that caliberating device is demarcated fast; The propelling movement hammer is provided with reciprocating device near the below; Demarcate annular groove and have installed inside tank through motor-driven column spinner is arranged, and the approaching part of column spinner and tank is provided with catch, monolithic top is run through and is shaped with drain gutter; Tank is provided with the import chute away from a side of caliberating device; Being provided with near the import chute can be to the coolant outlet pipe of water filling between catch; Tank is shaped with opening and the corresponding outlet chute that is provided with away from the opposite side of caliberating device.The motor-driven column spinner rotates catch in tank, form between a plurality of separate water proofs.Water pump is input to coolant outlet pipe with water, and injects between near the water proof of import chute.Cuttlefish to be calibrated is placed into the import chute, falls between corresponding water proof, and along with the below that turns to caliberating device between water proof.Caliberating device is injected the population intensifying device in the cuttlefish bone.Demarcated good cuttlefish and continued along with moving between water proof, and by the outlet chute discharge the centralized collection sterilization or directly through pipe to being discharged to the sea area of releasing.This device can be realized the streamlined operation, demarcates rapidly, is fit to extensive sea area and releases.
Be to optimize technique scheme, Adopts measure also comprises: slip pipe lower end bead is connected with the filling orienting lug group of reinforcing through coupling link; Filling orienting lug group is shaped with guiding surface.Filling orienting lug group is by a plurality of, generally 3 to 6 filling orienting lug monomer compositions, and between filling orienting lug monomer, each filling orienting lug monomer has guiding surface, the population intensifying device can be fallen in vertical mode after the guiding surface guiding, and fall in the mark orienting lug group of reciprocating device.
