Abstract
The trawlnet that the utility model provides, there is the string bag [1], there is pull rope [4] network interface [A] both sides, network interface has exaggerated and infraclass, exaggeratedly be connected with float [2], infraclass is connected with and heavily falls, and described heavy pendant is the roller [6] that an axle [5] and axle configure, and net bottom is also connected with float.The trawlnet that the utility model provides, substitutes the weight that infraclass connects with roller, and makes chance can not roll front at ordinary times and then not prick by hooking, has also been carried with float by net bottom simultaneously and made the whole not seabed interaction of the string bag.Compared with prior art, the utility model avoids the generation damaged by seabed reef.
Description
Technical field
The utility model provides a kind of trawlnet, especially a kind of as the trawlnet of tour itineraries confession visitor based on amusement.
Background technology
Along with the carrying out of tourism development, many visitors participate in recreational fishing activity for the purpose of experiencing, and wherein have one to be the trawlnet activity carried out by the sea.What the trawlnet experience carried out at present was used is by practical trawlnet scaled down version, has much inconvenience, can only carry out when mainly carrying out by the sea at sandy beach or mash, just can be pricked by hook damage as reef beach.Heavily fall because trawlnet infraclass is embroidered with, against seabed in phytal zone, running into stone of not redressing will be caught on.
Summary of the invention
For above-mentioned deficiency, the utility model is exactly the trawlnet that a kind of guiding principle off the net will be provided not land.
The trawlnet that the utility model provides, has the string bag, and there is pull rope network interface both sides, and network interface has exaggerated and infraclass, is exaggeratedly connected with float, and infraclass is connected with and heavily falls, and described heavy pendant is the roller that an axle and axle configure, and net bottom is also connected with float.
Described net bottom is the end of the string bag, is the other end of relative network interface.
The trawlnet that the utility model provides, substitutes the weight that infraclass connects with roller, and makes chance can not roll front at ordinary times and then not prick by hooking, has also been carried with float by net bottom simultaneously and made the whole not seabed interaction of the string bag.Compared with prior art, the utility model avoids the generation damaged by seabed reef.
The described string bag connects into wedge-like pocket by four mesh sheet, and four mesh sheet are respectively left and right sides triangle mesh sheet and upper and lower two panels rectangle mesh sheet, and around upper, four limits are all embroidered with float, gross buoyancy is less than the gravity of roller and axle thereof.
Described roller has multiple being arranged on equably on whole axle.
Structure like this makes the string bag farthest avoid net to touch seabed, only can closest to net just likely occurring by the problem hooked during waterside, and now activist has been to be at physical existence to net, available pole etc., and instrument removes to hook pricks, and do not make net damaged.
The trawlnet that the utility model provides, has two winch spools, and described two pull ropes are respectively connected with a winch spool, not only also must, by the operation of shake winch spool, can have more recreational for operated by two people.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment, in figure: the 1-string bag, 2-float, 3-winch spool, 4-pull rope, 5-axle, 6-roller, A-network interface.
Embodiment
As shown in Figure 1, have an amusement type trawlnet, by the wedge shape string bag 1 be made up of four mesh sheet, the string bag upper slice surrounding is all have float 2, bottom sheet front rope ties up on an axle 5, axle has been installed five spherical rollers 6.The network interface A formed by each mesh sheet front pulls open up and down through float and axle and roller.Two pull rope 4 one end tie up to axle two ends, and other end stake ties up on two winch spools 3 respectively, and crum shaft is equipped with rocking handle.
During use, first dropped in water in place far away by net with ship, the gravity due to axle and roller is greater than the gross buoyancy of float, and net is pressed into float under water and then the string bag is suspended in water.Two people shake winch spool simultaneously makes pull rope be dragged closely by net, until the pull-out water surface.During operation, two people must coordinate, therefore recreational stronger.
