Embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As Figure 1-Figure 4, the utility model provides is suitable for the barrier net that the large water surface fence of reservoir breeds fish and comprises 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 use polyethylene netting twines (are comprised of 3 line thighs, in every line thigh, contain 5 of polyethylene monofilaments, the line density of every monofilament is 42tex) adopt single fast knot and the comprehensive braiding of two 2 kinds of weaves of fast knot 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, and mesh pin length should be less than 1.44cm).The top of etting 7, middle and upper part and bottom are connected with floating guiding principle 5, waist guiding principle 6 and bottom line 8 respectively by 3～6mm polyethylene rope.
The spacing being provided with on floating guiding principle 5 between every group of float of many group float 4(4 can be adjusted as the case may be, if the spacing between every 2 floats is 1.0m～2.0m), the spacing being provided with in bottom line 8 between a plurality of gabion 9(gabions 9 can be adjusted as the case may be, if the spacing between every 2 gabions is 0.5～1m).As shown in Figure 3, the every group of float 4 in the utility model comprises 2 cylinders that be arranged in parallel 11, and it is made by foam, by 10mm polyethylene rope, ties up composition.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 arranging in the utility model comprises the mesh bag being sewn into by polyethylene rope and is filled in the stone in this mesh bag, in gabion 9, should not fill too much (overfill) stone, prevent from bursting mesh bag on the one hand, on the other hand, a little loosening tighter shakedown of gabion of being convenient to is pressed on high hollow uneven bed mud.
On floating guiding principle 5, be provided with a clump 1, this clump 1 is connected with a vertical rotating winch 2 by cable, this vertical rotating winch 2 can carry out folding and unfolding to clump, to reach, makes floating guiding principle 5 and etting 7 emerge and the avale object (respectively as shown in Fig. 2 (a) and Fig. 2 (a)) 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 is coaxial setting with pinion 14, pinion 14 is meshed with gear wheel 17, gear wheel 17 is coaxial setting with reel 15, arrange like this, the rotation of rotating steel rim 13 makes coaxial pinion 14 drive the gear wheel 17 of engagement, thereby easily rotates with the coaxial reel 15 of gear wheel 17.Vertical rotating winch 2 screws and is connecting the pulling winch hawser of crossing the floating guiding principle of ship navigation channel mouth net sheet, makes floating guiding principle 5 strain to assist fixing whole barrier net.
In the utility model, vertical rotating winch 2 is located on float 4, and this vertical rotating winch 2 can be arranged to small log cabin night shift room 3 so that personnel or goods boats and ships by time, open in good time and close " lock net ", prevent that in fence, fish escape.
The installing of the barrier net that the utility model provides and use are as follows:
If selection and the bottom surface of net position are leveled: establishing gulf, storehouse, net place mouth should be narrow unsuitable wide, and section should be less, and water is more shallow, is generally not more than 10m, and the depth of water changes little; Bank base is solid, and bottom is comparatively smooth, and substrate is preferably cohesive soil, is conducive to save material, and sets up and fixing barrier net; When reservoir low water level, water are more shallow, suitably arrange the falling zone that proposes net place, engaging bottom infraclass and gulf, storehouse mouth section while being convenient to dress net.
If the exploration of net place section and block are made: 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), according to section configuration figure, determine shape and the yardstick of block etting.In making, on block clothing, infraclass physical length should be than section long (loose) degree theoretical value ﹥ 15～20%; Height (deeply) degree of block is looked depth of water situation, should be than section depth theoretical value ﹥ 5～10%.
The installation of barrier net: barrier net etting is marked, and is respectively the stone pier of a 30～50kg in mark at A, O, the B3 point (infraclass two ends and mid point) of main block infraclass respectively after making; In establishing, install at net place and preliminary fastening floating guiding principle; By boats and ships, from establishing net mouth embankment one end, gulf, to the other end along floating guiding principle direction, lay the etting of the unassembled heavy stone of infraclass; Etting (exaggerated) and floating guiding principle are linked; Arrange, smooth-going infraclass, will " gabion " and infraclass link and compress infraclass; Reel is on the bank installed, with the fastening floating guiding principle of reel; Installing fastening waist guiding principle, link the etting of waist guiding principle and corresponding site; Installing float.
Ship pass mouth night shift room is installed and barrier net management: after barrier net installs, at the float place of crossing ship navigation channel, set up 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 and the vertical rotating winch that are fixed on floating guiding principle is connected.During cultivation, when having boats and ships to pass through block, small log cabin operator on duty unscrews the rotating steel rim of vertical rotating winch, put down ship pass mouth reserved floating guiding principle and etting, make ship current, after boats and ships " are crossed net ", screw again the rotating steel rim of vertical rotating winch, floating guiding principle and etting that pull-up ship pass mouth is reserved, recover the original shape of block, prevents cultured fishes flight in fence.
Small log cabin night shift room operator on duty, except being responsible for cultivation affairs and crossing the switching in ship navigation channel, should make regular check on, removes contamination and nurse block, prevents from escaping the accidents such as fish and occurs.
