Abstract
The utility model relates to a gillnet float, which is used on deep-sea fishing nets. The gillnet float is a claviform floating body with a hollow cavity, and both ends of the gillnet float are provided with binding rope grooves. The utility model is characterized in that the middle part of the claviform floating body is provided with a plurality of concave and convex reinforcing ribs, and the width of each reinforcing rib is 2 to 8 mm. The utility model provided with the constructional characteristics through the arrangement of the reinforcing rib structure can all reach the requirement of higher pressure resistant on the premise that the wall thickness is not increased and the buoyancy of the float is not damaged.
Description
The gill net float that the utility model is used about a kind of deep-sea fishing net.
Increase along with the aquatic product fishery dynamics, aquatic resources are subjected to influencing significantly, coastal waters shallow water catch descends significantly, fishing operation was forced to the deep-sea development in recent years, existing gill net Floater Structure is the hollow clavate buoyancy aid of a cavity, the surface circular arc is smooth, form by plastic material blowing, the requirement maximum of existing float operation can only adapt to depth of water deepwater work between 100 meters to 120 meters, if the depth of water is about 200 meters or darker, these gill net floats just can't be resisted the seawater pressure that increases considerably, the main path that in the past improved gill net float compressive property is the wall thickness that increases float, but faces supercharging significantly and continue to increase wall thickness and will lose float buoyancy and not reach the requirement of knotting.
The purpose of the utility model is exactly will overcome the deficiency that prior art exists and by changing the method for float force structure, make the gill net float reach the deep ocean work requirement.
This gill net float is the hollow clavate buoyancy aid of a cavity, and two ends are provided with watchman's wooden clapper rope groove, it is characterized in that being provided with some concavo-convex reinforcements in the middle of the clavate buoyancy aid, and its width is 2～8mm.
Have the setting of the utility model of said structure characteristics, under the prerequisite that does not increase wall thickness and infringement float buoyancy, can both reach higher requirement of withstand voltage by reinforcing rib structure.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously:
Fig. 1 is the utility model example structure cutaway view.
As shown in the figure, reinforcement 2 is a groove reinforcement among the utility model embodiment, relative groove, and this groove is preferably arc groove, well width is preferably 3～6mm, arc radius is 1.5～3mm, and the wall thickness of groove is suitable with other whole chamber wall thickness, that is to say much the same thickness, the reinforcement 2 that is provided with is at common size float, generally have 5～9 reinforcements 2 to get final product, select groove reinforcement 2 to be provided with axial watchman's wooden clapper rope groove 3 relatively, the structure setting is the most reasonable.
Claims (2)
