Abstract
The utility model relates to a measuring ruler of fishing mesh size, belonging to a measuring tool of fishing mesh size in order to provide a measuring ruler for inspecting conveniently and rapidly the small fishing mesh size in the spot, the utility model adopts a rigid measuring ruler countermarked with digital mark and is characterized in that the ruler body is flatly wedged, the inclination pitch of the inclined edge of the ruler body is 1 to 8, the head of the narrow end of the ruler body is arc-shaped, the narrow end of the ruler body is provided with a round hole, and the wide end of the ruler body is provided with a hand-held hole. The utility model relates applied for measuring the fishing mesh size.
Description
Technical field:
The utility model relates to fishing net mesh dimensional measurement instrument.
Background technology
Fishing net is because of the operating type difference, and the size of mesh difference is bigger.China's fishery law regulation bans use of less than the netting gear of minimum size of mesh fishes for, and implements in full minimum size of mesh system.Fish-farming operation fishing port superintendence at different levels administrative authority is according to GB 11779 " east, the minimum size of mesh of Huanghai Sea district trawlnet net capsule " and GB 11780 " the minimum size of mesh of Nanhai District trawlnet net capsule ", SC4008-1983 " the minimum size of mesh of silvery pomfret drift net ", SC 4009-1983 " the minimum size of mesh of Chinese herring drift net ", the regulation of SC 4010-1983 " the minimum size of mesh of scomberomorus niphonius drift net " and SC 4013-1983 " the minimum size of mesh of chord net net capsule is arranged " standard is checked the minimum size of mesh of above-mentioned netting gear.So-called size of mesh is inner diameter of mesh, mesh size and bar size.Inner diameter of mesh is meant when mesh is fully stretched, the distance between two diagonal angle knot or the tie point inner edge.Mesh size is meant when mesh is fully stretched, the distance between two diagonal angle knot or the tie point center.Bar size is meant between the center of two adjacent bonds or tie point when the order pin and fully stretches and the distance of not extending.Existing fishing net mesh dimension measurement method (GB/T 6964-1986 " fishing net mesh dimension measurement method ") is the small-mesh fishing net of the inner diameter of mesh 66mm～124mm that can measure in the laboratory.The instrument of the measurement inner diameter of mesh of regulation is steel ruler or vernier caliper among the GB/T 6964-1986 " fishing net mesh dimension measurement method ".When being defined in the size of mesh measurement among the GB/T 6965-2004 " gear material test pacing items pre-tension ", the tension force that is added in advance on each order pin should equal the deadweight of the 250m ± 25m length of same material, specification netting twine.The survey instrument and the pre-tension of the inner diameter of mesh of stipulating in above-mentioned two standards, the professional aids in Other Instruments equipment and can implement in the laboratory, but it is also cumbersome to operate, and requires crewman, fish-farming operation personnel almost cannot in the correct enforcement of fishing boat and fishing port.The equipment that does not also have at present the inner diameter of mesh of scene detection quickly and easily, this has just restricted Production Management of Fisheries, give to fish for and brought hidden danger, press for a kind of on-the-spot quickly and easily dip stick that detects the small-mesh fishing net inner diameter of mesh with the sustainable sound development of fishery.
The utility model content
The utility model technical issues that need to address provide a kind of on-the-spot quickly and easily dip stick that detects the small-mesh fishing net inner diameter of mesh.
The utility model adopts mint-mark figure notation rigidity gage, it is characterized in that the chi body is flat wedge shape, and the gradient of chi body hypotenuse is 1 to 8, and the narrow termination portion of chi body is in the arc-shaped, and the narrow end of chi body has a circular hole, and the wide end of chi body has a hand-hold hole.
The utility model is pressed the required standard of fishing net mesh dimension measurement method and gear material test pacing items pre-tension, quickly and easily with dip stick perpendicular to the fishing net plane along knotted netting vertically or the long axis direction of knotless netting insert mesh, just can on-the-spotly detect inner diameter of mesh, show that through the demonstration testing interpretation of result technical indicator is practical, rationally reliable.
Description of drawings
What accompanying drawing was represented is the utility model fishing net mesh inner diameter measurement chi.
Embodiment
Implement best way of the present utility model below in conjunction with description of drawings: the utility model chi body adopts rigid material to make, as stainless steel, aluminium alloy, alloy steel or rigidity plastics; Chi body thickness 3mm, all thickness direction corners of chi body are in the arc-shaped, and arc radius is 1.5mm, can avoid sharp edges to damage netting twine or cut-out fishing net mesh when inner diameter of mesh is measured; The flat wedge shape of the external formation of chi, the gradient of chi body hypotenuse is 1 to 8; Inner diameter of mesh dip stick number of division word mark from the narrow end 4 last 30mm of range arm body along the wide mint-mark 66mm～124mm of hypotenuse 3mm for ease of reading, also has scale mark in the center line both sides of dip stick, and the scale interval of range is 1mm; The head of the narrow end 4 of chi body is in the arc-shaped 5, and it is 8mm circular hole 2 that the narrow end 4 of chi body has a diameter, and circular hole 2 is used for hook spring balance when applying pre-tension; The wide end 3 of chi body has a hand-hold hole, and hand-hold hole growth strip gab 1 grips usefulness for hand during measurement; The chi surface is coated with corrosion-inhibiting coating can be in case seawater, water or other liquid corrosion keep the chi face clear.
When measuring inner diameter of mesh, hand grips the opening 1 of the wide end 3 of inner diameter measurement chi, with the narrow end 4 of inner diameter measurement chi perpendicular to the net plate plane that stretches along knotted netting vertically or the long axis direction of knotless netting insert mesh, circular hole 2 with the narrow end 4 of spring balance hook inner diameter measurement chi, pre-tension (pressing GB/T 6965-2004 regulation) with regulation inserts mesh with dip stick at the maximum inner diameter place, till dip stick is blocked by mesh.Dip stick be stuck the place width be this inner diameter of mesh.During measurement, read the width number, to guarantee all to obtain identical numerical value on the both sides of dip stick in the top of netting twine (or order payment to a porter).Measure 20 continuous meshes, its arithmetic mean is the inner diameter of mesh of this time measurement.
Inner diameter of mesh is the key technical indexes of fishing net, the management of the fishing net mesh internal diameter that on-the-spot quickly and easily detection fishing net directly has influence on.The utility model shows that through the demonstration testing interpretation of result technical indicator is practical, and is rationally reliable.
