Abstract
The utility model relates to a kind of trawl door structure.Its structure comprises web plate main body, and described web plate main body comprises top panel, lower panel and side plate, and the lower panel of described web plate main body is evenly equipped with the multiple rollers contacted with sea bottom surface.The utility model drives trawlnet to move by the roller in web plate main body, time saving and energy saving, and roller seabed interaction is rolling friction, little on the impact in seabed, can not destroy the ecological environment in seabed.
Description
Technical field
The utility model relates to a kind of trawl door structure.
Background technology
Trawlnet is a kind of instrument of fishing for for fishery, and its concrete structure is made up of etting and the web plate that is connected with etting.When fishing operation, be first put net, namely by web plate, etting stretched out so that treat that fishing group enters in etting, after the shoal of fish enters etting, then carry out receipts net, by web plate, etting is withdrawn near hull.Due in this course, web plate is generally rigid structural, and when dragging web plate and driving etting to move, the web plate of rigidity directly can contact with surface, seabed, thus the ecological environment in destruction seabed, be unfavorable for the foundation of algae bed and the growth of marine alga.
Summary of the invention
In view of the foregoing, the utility model provides a kind of trawl door structure, and this trawl board can effectively prevent web plate to the destruction of seabed ecological environment.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of trawl door structure, comprise web plate main body, described web plate main body comprises top panel, lower panel and side plate, and the lower panel of described web plate main body is evenly equipped with the multiple rollers contacted with sea bottom surface.
Further, counterweight sinker is provided with between multiple rollers of described lower panel.
Further, the top panel of described web plate main body and side plate are also evenly equipped with multiple roller.
Further, described web plate main body is rectangle structure.
Further, described web plate main body is ellipsoidal structure.
Further, the lower panel of described web plate main body is distributed with flexible cover sheet.
The beneficial effects of the utility model are: the utility model drives trawlnet to move by being provided with roller in web plate main body, time saving and energy saving, and roller and seabed are rolling friction, little on the impact in seabed, can not destroy the ecological environment in seabed.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of description, and can become apparent to allow above-mentioned purpose of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the utility model trawl door structure schematic diagram.
Fig. 2 is the oval trawl door structure schematic diagram of the utility model.
Detailed description of the invention:
For further setting forth the utility model for the technological means reaching predetermined object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to the detailed description of the invention of the trawl door structure that the utility model proposes, structure, feature and effect thereof, be described in detail as follows.
As shown in Figure 1, a kind of trawl door structure of the utility model, comprise web plate main body 1 and multiple roller 2, described web plate main body 1 comprises top panel 3, lower panel 4 and side plate 5.
Described roller 2 is arranged on the lower panel 4 of web plate main body 1 lower end, and roller 2 is multiple, and is distributed on the lower panel 4 of web plate main body 1, between each roller 2, be also provided with counterweight sinker.When web plate main body 1 moves, web plate main body 1 is driven to move, below lower panel 4 is generally placed in by roller 2, when seabed is moved, owing to being rolling friction between the roller 2 on lower panel 4 and seabed, effectively can reduce the impact on seabed, can not damage the ecological environment in seabed.
The top panel 3 of described web plate main body 1 and side plate 5 are also evenly equipped with multiple roller 2.Make trawlnet in moving process, other faces of web plate main body 1 also can contact with seabed sea bed sometimes, can utilize roller 2 seabed interaction on it, can not damage like this to seabed ecological environment.
Described web plate main body 1 can be rectangle structure, shown in Figure 1.Certain web plate main body 1 also can be ellipsoidal structure, shown in Figure 2, and roller 2 is arranged along the periphery of web plate main body 1.
The lower panel of described web plate main body 1 also can be distributed with flexible cover sheet, avoid rigidity plate to contact with the direct of seabed, alleviate the destruction to seabed ecology further.
The above, be only the detailed description realizing the utility model specific embodiment and graphic that the utility model description describes, unrestricted for illustration, but feature of the present utility model is not limited thereto, those skilled in the art obviously understand, all scopes of the present utility model should be as the criterion with the protection domain of its claim, under the prerequisite not deviating from invention spirit that appended claims defines and invention scope, all other embodiments implemented according to spirit of the present utility model change similar with it, all should be included among protection category of the present utility model.
