Abstract
The invention relates to a device used in the operation technology for using a barrier net to bar fish, in particular to a fish barring device of an ascending type waterway barrier net. The device mainly consists of a main barrier net, a covering net, and an ascending channel floppa. The part of the main barrier net at the channel is provided with a navigation gap which is connected with the ascending channel floppa, float lines at two sides of the main net are connected to the covering net which partially floats on the water surface. In navigation, the ascending channel floppa overturns downwards under the action of a downward drawing force. After a ship passes, the drawing force is eliminated, and the floppa is raised to the water surface.
Description
Technical field
The present invention relates to a kind of is to guarantee the navigation requirement in reservoir, lake, rivers breed waters, implements to block the device of fish operation technique, especially relates to a kind of device for blocking fish with barrier net in ascending sea-route.
Background technology
Cut apart when carrying out aquaculture by water body in waters such as lake, rivers at present, general way is directly to cut apart water body with block, for guaranteeing navigation, on block the navigation channel is set directly, and during navigation, block sinks.Because of the influence of factors such as wind-engaging, current and navigation sinkings, consider again that fish have to trace back and along the habit of net activity, the probability of net escape can be very big more for fish that it is not fine blocking the fish effect.
Summary of the invention
The present invention mainly is that the technical problem that solves provides a kind of fish to net the escape probability more low, the device for blocking fish with barrier net in ascending sea-route easily of opening the navigation or air flight.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: establish a navigation breach at the place, navigation channel, top of main hurdle net, this design makes not to be needed when navigation the whole sinking of major network.The main block headline place of breach both sides is connected with cover net.When being subjected to stormy waves and influencing office's cloth and sink,, can not cause fish to get over net owing to there is cover net to bubble through the water column when raising to the higher plane of principle yet.The navigation indentation, there is connecting the adaptive with it floppa that rises, and rises floppa and overturns downwards when navigation.Like this, in the navigation process, can depress the fish lid of swimming over to the place, navigation channel heavy when floppa sinks and can't get over net, improve greatly and blocked the fish effect.
As a kind of preferred structure of the present invention, the headline of main hurdle net is located under the horizontal plane, bubbles through the water column in the top of cover net.This design has been saved to greatest extent and has been used web area, and also the action effect of cover net has also obtained best embodiment simultaneously.
As a kind of preferred structure of the present invention, it is dustpan-shaped to rise being shaped as of floppa, and nearly main block one end width is big, highly be 4-8 rice, and the width of the main end of blocking far away is little, highly is zero.Flow velocity when this design has strengthened the water current on the one hand through the navigation channel breach reduces the difficulty that fish escape; Also reduce the area of escaping gap on the other hand, reduced fish escape probability.
As a kind of preferred structure of the present invention, the bottom that rises the floppa big opening end is connected with the periphery of main block navigation channel breach, and top is connected with the cover net of both sides.This connected mode makes the each several part of device obtain effective combination.
As a kind of preferred structure of the present invention, the end that rises floppa stretches to downstream one side in navigation channel, and the headline that rises floppa is bubbled through the water column.This design makes that to rise floppa tightr with being connected of cover net, also is to have the habit of tracing back to design according to fish.
As a kind of preferred structure of the present invention, main block and the headline that rises floppa all are provided with and are evenly distributed, the ball float of reasonable quantity.Play positioning action.
The utility model blocks the fish technology with respect to existing block following advantage: at first, it is effective to block fish, has reduced the probability that fish escape greatly, easy to operate when having guaranteed navigation simultaneously, and also simple in structure, easy to make.Be very beneficial for the large-scale popularization in fish production.
Description of drawings
Accompanying drawing 1 is the structural representation of device for blocking fish with barrier net in ascending sea-route of the present invention.
Accompanying drawing 2 is structural representations of the floppa of device for blocking fish with barrier net in ascending sea-route of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail.
Accompanying drawing 1 is a kind of structural representation of the present invention, and accompanying drawing 2 is structural representations of the floppa of device for blocking fish with barrier net in ascending sea-route of the present invention.As seen from the figure, the bottom of device is a main hurdle net 1, and length is 450 meters, and height is 40 meters.The online portion in main hurdle is provided with the navigation breach at the place, navigation channel, and length is 80 meters, highly is 3 meters.It highly is 6 meters cover net 3 that the main block headline place of navigation breach both sides is connected with, and bubbles through the water column in the top of cover net, is subjected to the stormy waves influence and when fluctuating at main block, and it is unaffected that cover net can keep blocking the effect of fish.The navigation indentation, there is connecting the adaptive with it floppa 5 that rises, and it is dustpan-shaped to rise being shaped as of floppa, and nearly main block one end width is 80 meters, highly be 4-8 rice, and the block width of an end of master far away is 60 meters, highly is zero.The 3 meters high peripheries with main block navigation channel breach in bottom that rise road floppa big opening end are connected, and 3 meters on top is connected with the cover net of both sides, and end stretches to downstream one side in navigation channel, and headline 4 is bubbled through the water column.Main block and the headline 2,4 that rises floppa all are provided with the ball float of even distribution, reasonable quantity.Entire equipment is cut by the waist in the navigation channel.During navigation, draw high floppa downwards, after shipping agency is crossed, decontrol and rise floppa, return to the origin-location.
