Description
Technical field
A kind of dip angle of steel warp measurement mechanism and the measuring method thereof that the present invention relates to use in the trawling.
Background technology
Trawlnet is one of fishing gear that better results in the present marine fishery production, also is important a kind of in traditional fishing gear, belongs to the initiative fishing gear.Draging guiding principle is the intermediate hub that connects trawlboat and netting gear, therefore, drags guiding principle and play key effect in the trawling process.It is significant to understand the production practices and the netting gear research of draging the tension force bull trawl of guiding principle in the time of trawling, because drag the distortion of guiding principle, the towing speed that tension force directly has influence on the trawler operation, the consumption of fuel etc.And dip angle of steel warp is to analyze to drag guiding principle distortion, a stressed important parameter.So-called dip angle of steel warp is exactly the angle that drags between guiding principle and the surface level.The principle that traditional angular instrument or inclinator adopt generally all is to make 0 scale mark of protractor parallel with surface level, and measures pointer parallel with measured object (or coincidence).Above-mentioned two parallelly can easily realize on land, but on the sea of fishing boat operation, the comparison difficulty is just arranged.Reason is: one, drag guiding principle identity distance off sea and have wave frequently from far away and sea; Two, drag guiding principle in motion.So can there be bigger error in the inclination angle of using traditional inclinator measurement to drag guiding principle, and inconvenient operation.
Summary of the invention
The dip angle of steel warp measurement mechanism and the measuring method thereof that the purpose of this invention is to provide a kind of with low cost, simple to operate, sturdy and durable and easy disassembly are to satisfy the requirement of accurately measuring dip angle of steel warp under this special environment of trawlboat.
The present invention adopts and measures pointer perpendicular to draging guiding principle, and allows 0 scale mark vertical all the time (vertical level just) downwards of measuring disk.Utilize the right-angle triangle principle, measure pointer on measuring disk right angle be exactly the inclination angle of draging guiding principle.
The present invention includes measuring disk and measure pointer, it is characterized in that also comprising that there is the pedestal in the hole of stationary fixture at two ends, these anchor clamps fixedly drag guiding principle on the pedestal of rectangular parallelepiped, rely on the center pit on column and the pedestal that the measuring disk activity is fixed on the pedestal, and have the screw on bolt and the pedestal will measure the pointer vertical fixing in pedestal, 0 scale place of measuring disk hangs with weight via aperture.
Dip angle of steel warp measuring method of the present invention, at first column is passed the circle center hole of measuring disk and the center pit of pedestal, it is fixing with nut pedestal and measuring disk to be carried out activity again, to measure the pointer vertical fixing on pedestal with bolt and screw then, with the hole of anchor clamps and pedestal pedestal is fixed in and drags on the guiding principle, at last weight is hung on the aperture of measuring disk and can measures.When measuring the pointer indication when stablizing, pointer right angle be exactly the dip angle of steel warp that will measure.
The present invention is simple in structure, easy to operate, measurement is accurate, cheap.In addition, the present invention can also conveniently dismantle preservation after measuring end.

Embodiment
As Fig. 1-Fig. 3, the present invention includes measuring disk 2 and measure pointer 3, it is characterized in that also comprising that there is the pedestal 1 in the hole 10 of stationary fixture 5 at two ends, anchor clamps 5 fixedly drag guiding principle on the pedestal 1 of rectangular parallelepiped, rely on the center pit 11 on column 7 and the pedestal 1 that measuring disk 2 activities are fixed on the pedestal 1, and have the screw 12 on bolt 9 and the pedestal 1 will measure pointer 3 vertical fixing in pedestal 1,0 scale place of measuring disk 2 hangs with weight 4 via aperture 14.Be that above-mentioned pedestal 1, measurement pointer 3 and measuring disk 2 etc. have constituted the basic structure that can conveniently dismantle of the present invention.
The length of above-mentioned pedestal 1 is 35cm, and wide is 8cm, and height is 5cm.
Above-mentioned measuring disk 2, measurement pointer 3 are all made with stainless steel material.
Above-mentioned measuring disk 2 is the protractor that the circular discs of 20cm is formed by radius, and the thickness of disk is 1cm, and angular range is 0-180 °, and minimum scale is 1 °.In addition, measuring disk 0 scale place has an aperture 14 to be used for hanging weight 4, and is vertical all the time downwards with 0 scale that guarantees measuring disk 2.
Terminal bolt is that diameter is that 1cm, length are 4cm before the above-mentioned column 7, and the rear end is a cap-like structure.
As Fig. 1-Fig. 3, the present invention measures the dip angle of steel warp method, earlier column 7 is passed the circle center hole 13 of measuring disk 2 and the center pit 11 of pedestal 1, it is fixing with nut 8 pedestal 1 and measuring disk 2 to be carried out activity again, to measure pointer 3 vertical fixing on pedestal 1 with bolt 9 and screw 12 then, with the hole 10 of anchor clamps 5 and pedestal 1 pedestal 1 is fixed in and drags on the guiding principle 6, at last weight 4 is hung on the aperture 14 of measuring disk 2 and can measures.When measuring pointer 3 and stablize, pointer right angle be the dip angle of steel warp of measurement.
