Abstract
The utility model relates to marine aquaculture apparatus, particularly relates to a kind of crashworthiness blue crab cultivation net cage, comprises circular upper frame, underframe and is connected to the metal etting between upper frame, underframe.This structure also includes several anti-percussion devices arranged around metal etting even circumferential; This anti-percussion device includes a fixed head along the radial projection of upper frame, along No. two fixed heads of the radial projection of underframe, the cylinder wheel being vertically connected to the wheel shaft between a fixed head, No. two fixed heads and being set in outside wheel shaft, a fixed head, No. two fixed heads are mutually corresponding, leave space between cylinder wheel and metal etting outer wall.Impulsive force when the utility model slows down shock by the rolling action of cylinder wheel, drives and bumps against net cage and stagger, thus prevent from continuing to impact the damage brought, possess good crashworthiness protective effect, substantially prolongs the service life of net cage.
Description
Technical field
The utility model relates to marine aquaculture apparatus, particularly relates to a kind of crashworthiness blue crab cultivation net cage.
Background technology
Cage culture is a kind of blue crab cultivation new method of rising in recent years, has the advantage that breeding density is large, growth is rapid, the incidence of disease is low, be easy to management and fish for.Usually be equipped with the anchoring device playing firm control action in existing blue crab cultivation net cage, make net cage be subject to certain traction and can not be arbitrarily floating with water body flow direction.But work as spring tide season, typhoon season temporarily, sea beat is very violent, anchoring device may because of being difficult to keep out too fast water volume flow rate and huge wave bounces and lost efficacy, net cage loses and pins down and float arbitrarily loose, easily breakage is bumped against between two between net cage, mud crab escapes in a large number, brings great economic loss.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above; and a kind of crashworthiness blue crab cultivation net cage is provided; when there is certain contact-impact in net cage; make both be separated rapidly and avoid continuing increasing the weight of clashing into that the etting caused is damaged, mud crab escapes; available protecting net cage, significantly extends its service life.
The technical solution of the utility model is:
A kind of crashworthiness blue crab cultivation net cage described in the utility model, comprise circular upper frame, underframe and be connected to the metal etting between upper frame, underframe, it is characterized in that: also include several anti-percussion devices, several described anti-percussion devices are arranged around metal etting even circumferential; Described anti-percussion device includes a fixed head along the radial projection of upper frame, along No. two fixed heads of the radial projection of underframe, the cylinder wheel being vertically connected to the wheel shaft between a fixed head, No. two fixed heads and being set in outside wheel shaft, a described fixed head, No. two fixed heads are mutually corresponding, leave space between described cylinder wheel and metal etting outer wall.
Above structure, the utility model can play himself defense mechanism, reaches the object effectively preventing from colliding.Described cylinder wheel, as the main impetus clashed into when occurring, rolls around its wheel shaft when clashing into stressed, and make net cage along the slip of cylinder wheel tangential direction, two collision net cages stagger separation mutually thus, avoid the secondary under water impact to collide.
Further, in a kind of crashworthiness blue crab cultivation net cage described in the utility model, described cylinder wheel height is 0.8-0.9 times of axle articulation.
Further, in a kind of crashworthiness blue crab cultivation net cage described in the utility model, the central axis of described cylinder wheel overlaps completely with the central axis of wheel shaft.
Further, in a kind of crashworthiness blue crab cultivation net cage described in the utility model, the quantity of described anti-percussion device is no less than 8, and spacing is excessive and cause impact resistance effect to decline between two effectively can to avoid anti-percussion device, and metal etting is damaged.
Further, in a kind of crashworthiness blue crab cultivation net cage described in the utility model, a described fixed head and upper frame, No. two adopt welding manner to be connected between fixed head with underframe, connect more firm.
The beneficial effects of the utility model are:
1, impulsive force when the utility model slows down shock by the rolling action of cylinder wheel, drives and bumps against net cage and stagger, thus prevent from continuing to impact the damage brought, possess good crashworthiness protective effect, substantially prolongs the service life of net cage.
2, rational in infrastructure, technique is simple, low processing cost, is easy to promote realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of crashworthiness blue crab cultivation net cage described in the utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described:
With reference to shown in Fig. 1, a kind of crashworthiness blue crab cultivation net cage disclosed in the present embodiment, the metal etting 3 comprising circular upper frame 1, underframe 2 and be connected between upper frame 1, underframe 2.The innovative point of the present embodiment is: also include several anti-percussion devices 4 in the present embodiment, and several described anti-percussion devices 4 are arranged around metal etting 3 even circumferential.And efficiently can play its crashworthiness effect in order to ensure the present embodiment, anti-percussion device 4 spacing is not easily crossed thin excessive, and therefore the quantity of anti-percussion device 4 described in the present embodiment is no less than 8.
Described in the present embodiment, the concrete structure of anti-percussion device 4 is described as follows: described anti-percussion device 4 includes a fixed head 5 along the radial projection of upper frame 1, along No. two fixed heads 6 of the radial projection of underframe 2, the cylinder wheel 8 being vertically connected to the wheel shaft 7 between a fixed head 5, No. two fixed heads 6 and being set in outside wheel shaft 7, a described fixed head 5, No. two fixed heads 6 are mutually corresponding, and a described fixed head 5 adopts welding manner to be connected with No. 1, two, upper frame between fixed head 6 with underframe 2.It should be noted that and leave space between described cylinder wheel 8 and metal etting 3 outer wall, ensure that cylinder wheel 8 has enough rotation spaces, this is the key point that the present embodiment plays its impact resistance effect.
In the present embodiment, the central axis of described cylinder wheel 8 overlap completely with the central axis of wheel shaft 7 and described cylinder wheel 8 highly for wheel shaft 7 height 0.8-0.9 doubly.
The impact resistance principle of the present embodiment is: when sea beat power is excessive, net cage departs from its anchoring device and collides with other net cages.In the moment that collision occurs, described cylinder wheel 8 plays carrying stressed effect rolling around its center-wheel arbor 7 under impact effect, and net cage is sliped off along its tangential direction, and two collision net cages stagger separation thus, can effectively prevent deep shock.
Specific embodiment described herein is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses as long as have in art, must be contained by claim of the present utility model.
