Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but the present invention is not limited to following examples.
As Figure 1-Figure 4, be provided by the inventionly suitable for the barrier net that the large water surface fence of reservoir breeds fish and comprise etting 7, floating guiding principle 5, waist guiding principle 6 and bottom line 8; Wherein, floating guiding principle 5, waist guiding principle 6 and bottom line 8 are the polyethylene rope that diameter is 10 ~ 14mm, etting 7 polyethylene netting twine (is made up of 3 line stocks, containing polyethylene monofilament 5 in every root line stock, the line density of every root monofilament is 42tex) adopt single fast knot and two fast knot 2 kinds of weaves comprehensively to weave to form, and the mesh pin length of etting 7 should be no more than the 3/25(of cultured fishes fingerling total length as Tilapia mossambica fingerling total length 12cm, then mesh pin length should be less than 1.44cm).Top, the middle and upper part of etting 7 are connected with bottom line 8 with floating guiding principle 5, waist guiding principle 6 by 3 ~ 6mm polyethylene rope respectively with bottom.
Floating guiding principle 5 is provided with the spacing how group float 4(often organizes between float 4 can adjust as the case may be, if the spacing between every 2 floats is 1.0m ~ 2.0m), spacing bottom line 8 is provided with between multiple gabion 9(gabion 9 can adjust as the case may be, if the spacing between every 2 gabions is 0.5 ~ 1m).As shown in Figure 3, the float 4 of often organizing in the present invention comprises 2 cylinders be arranged in parallel 11, and it is made up of foam, ties up composition by 10mm polyethylene rope.And these 2 cylinders 11 are connected by a cuboid galvanized steel pipe support 10, and float 4 is linked by polyethylene rope and this cuboid galvanized steel pipe support 10.The gabion 9 arranged in the present invention comprises the mesh bag be sewn into by polyethylene rope and the stone be filled in this mesh bag, too much (overfill) stone should not be filled in gabion 9, on the one hand prevent from bursting mesh bag, on the other hand, a little loosen and be convenient to gabion and body more closely spread and be pressed on high hollow uneven bed mud.
Floating guiding principle 5 is provided with a clump 1, and this clump 1 is connected with a vertical rotating winch 2 by cable, and this vertical rotating winch 2 can carry out folding and unfolding to clump, to reach, floating guiding principle 5 and etting 7 is emerged and avale the object of the water surface.As shown in Figure 4, vertical rotating winch 2 comprises rotating steel rim 13, pinion 14, gear wheel 17, reel 15 and pedestal 16; Wherein, rotating steel rim 13 and pinion 14 are coaxial setting, pinion 14 is meshed with gear wheel 17, gear wheel 17 and reel 15 are coaxial setting, such setting, the rotation of rotating steel rim 13 makes coaxial pinion 14 drive the gear wheel 17 of engagement, thus the reel 15 that ease rotation follows gear wheel 17 coaxial.Vertical rotating winch 2 screws and was connected to the pulling winch hawser that ship navigation channel mouth mesh sheet floats guiding principle, and floating guiding principle 5 is strained with auxiliary fixing whole barrier net.
In the present invention, vertical rotating winch 2 is located on float 4, and this vertical rotating winch 2 can be arranged at small log cabin night shift room 3, so that when personnel or cargo vessel pass through, open and close " lock net " in good time, prevents fish in fence from escaping.
Installing and the use of barrier net provided by the invention are as follows:
If the selection of net position and bottom surface are leveled: establish gulf, storehouse, net place mouth suitable narrow unsuitable wide, section should be less, and water is more shallow, is generally not more than 10m, and water depth ratio is little; Bank base is solid, and bottom is comparatively smooth, and substrate is preferably cohesive soil, is conducive to saving material, and sets up and fixing barrier net; When reservoir low water level, water are more shallow, suitably arrange the falling zone proposing net place, joint when being convenient to fill net bottom infraclass and gulf, storehouse mouth section.
If the exploration of net place section and block make: the width of net place section and the degree of depth of bottom different loci are established in exploration, retouch roughly section configuration figure processed (theoretical parameter), determine shape and the yardstick of block etting according to section configuration figure.In making, on block clothing, infraclass physical length should than section length (loose) topology degree value ﹥ 15 ~ 20%; Height (deeply) degree of block looks depth of water situation, should than section depth theoretical value ﹥ 5 ~ 10%.
The installation of barrier net: barrier net etting is marked at A, O, B3 point (infraclass two ends and mid point) of main block infraclass respectively, and is respectively the stone pier of one piece of 30 ~ 50kg in mark after making; Install and preliminary fastening floating guiding principle in establishing net place; By boats and ships from the etting establishing net mouth embankment one end, gulf to the other end along the unassembled heavy stone of floating guiding principle direction laying infraclass; Etting (exaggerated) and floating guiding principle are linked; Arrangement, smooth-going infraclass, link " gabion " and infraclass and compress infraclass; Reel is on the bank installed, with the fastening floating guiding principle of reel; Install and fastening waist guiding principle, the etting of waist guiding principle and corresponding site is linked; Installing float.
Ship pass mouth night shift room is installed and barrier net management: after barrier net installs, set up at the float place crossing ship navigation channel and fix small log cabin night shift room, then vertical rotating winch is mounted and fixed on small log cabin night shift room, with cable, the clump be fixed on floating guiding principle and vertical rotating winch is connected.During cultivation, when there being boats and ships to need by block, small log cabin operator on duty unscrews the rotating steel rim of vertical rotating winch, put down the reserved floating guiding principle of ship pass mouth and etting, allow ship pass through, after boats and ships " cross net ", screw the rotating steel rim of vertical rotating winch again, the floating guiding principle that pull-up ship pass mouth is reserved and etting, recover the original shape of block, prevents cultured fishes flight in fence.
Small log cabin night shift room operator on duty is except responsible cultivation affairs and cross except the opening and closing in ship navigation channel, should make regular check on, removes contamination and nurse block, prevents escaping the accidents such as fish and occurs.
