The solution that the utility model solves its technical problem is: coastal waters demersal fishes sample collecting device, it comprises main rope, one end of described main rope is provided with stainless steel and props up, the other end that described stainless steel props up is in series with a plurality of fishings unit, in each fishing unit, at least one fish hook is all installed, the two ends that stainless steel props up are all provided with nylon rope, and stainless steel props up with two nylon ropes and forms a triangular form structure, and traction weight is installed on the tie point of two nylon ropes.
Further improvement as technique scheme, described fishing unit comprises auxiliary rope, is arranged on the triangle change of auxiliary rope end and is arranged on the branch line in triangle change, described auxiliary rope is connected with the triangle change of main rope or a upper fishing unit, described fish hook is arranged on branch line, straight line change is installed between described fish hook and branch line, described stainless steel prop up and the auxiliary rope of first fishing in unit between straight line change is installed.
As the further improvement of technique scheme, between described main rope and stainless steel prop up, straight line change is installed, between the tie point of two nylon ropes and traction weight, straight line change is installed.
As the further improvement of technique scheme, the length of described auxiliary rope is greater than the length of branch line.
As the further improvement of technique scheme, first contact that is arranged in the triangle change of a last fishing unit is connected with auxiliary rope, and its second contact is connected with branch line, and its 3rd contact is provided with branch line and fish hook.
The beneficial effects of the utility model are: the utility model arranges traction weight and fishing unit by the one end at main rope, during fishing, one end of main rope is tied up to staff on hand, on fish hook, load onto bait, traction weight and fishing unit are put into marine, fishing unit enters coastal waters deep layer or bottom under the gravity of traction weight drives, and staff pulls up and down main rope and then lures fish to rise to the bait, such fishing device is with low cost, simple to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiment that those skilled in the art obtains under the prerequisite of not paying creative work, all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in literary composition, not singly refer to that member directly joins, and refer to and can by adding or reducing, connect auxiliary according to concrete performance, form more excellent draw bail.
With reference to Fig. 1, coastal waters demersal fishes sample collecting device, it comprises main rope 1, one end of described main rope 1 is provided with stainless steel and props up 2, stainless steel props up 2 its supporting roles, described stainless steel props up 2 the other end and is in series with a plurality of fishings unit, the quantity of fishing unit is generally 5 ~ 7, in each fishing unit, at least one fish hook 8 is all installed, stainless steel props up 2 two ends nylon rope 3 is all installed, stainless steel props up 2 and two nylon ropes 3 and forms Stability Analysis of Structures after a triangular form structure, traction weight 5 can not prop up 2 rotations around stainless steel, be beneficial to traction weight 5 and in coastal waters deep layer or bottom, keep stable, article two, traction weight 5 is installed on the tie point of nylon rope 3.Traction weight 5 is plummet.The degree of depth that need to fish according to difference is installed the plummet of the rhombus of different quality on the tie point of two nylon ropes 3.
By the one end at main rope 1, traction weight 5 and fishing unit are set, during fishing, by one end of main rope 1 tie up to staff on hand after, on fish hook 8, load onto bait, traction weight 5 and fishing unit are put into marine, fishing unit enters coastal waters deep layer or bottom under the gravity of traction weight 5 drives, and staff pulls up and down main rope and then lures fish to rise to the bait, such fishing device is with low cost, simple to operate.
