Embodiment
The present invention will be further described below in conjunction with accompanying drawing, but the present invention is not limited to following examples.
As Fig. 1-shown in Figure 4, provided by the inventionly be suitable for the barrier net that the big 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 usefulness polyethylene netting twines (are made up of 3 line thighs, contain 5 of polyethylene monofilaments in the every line thigh, 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 3/25(such as the Tilapia mossambica fingerling total length 12cm of cultured fishes fingerling total length, and then 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.
Can adjust as the case may be in the spacing that floating guiding principle 5 is provided with between every group of float of many group float 4(4, be 1.0m～2.0m) as the spacing between per 2 floats, can adjust as the case may be in the spacing that bottom line 8 is provided with between a plurality of gabion 9(gabions 9, be 0.5～1m) as the spacing between per 2 gabions.As shown in Figure 3, the every group of float 4 among the present invention comprises 2 cylinders that be arranged in parallel 11, and it is made by 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 that arranges among the present invention comprises the mesh bag that is sewn into by the polyethylene rope and the stone that is filled in this mesh bag, should not adorn too much (overfill) stone in the gabion 9, prevent from bursting mesh bag on the one hand, on the other hand, a bit loosening tighter shakedown of gabion of being convenient to is pressed on the high hollow uneven bed mud.
Be provided with a clump 1 at floating guiding principle 5, 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, makes floating guiding principle 5 and etting 7 emerge and the avale purpose of the water surface to reach.As shown in Figure 4, vertical rotating winch 2 comprises rotation steel ring 13, pinion 14, gear wheel 17, reel 15 and pedestal 16; Wherein, rotation steel ring 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 rotation steel ring 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, and floating guiding principle 5 is strained with auxiliary fixing whole barrier net.
Among the present invention, vertical rotating winch 2 is located on the float 4, and this vertical rotating winch 2 can be arranged at small log cabin night shift room 3 so that personnel or goods boats and ships by the time, open in good time and close " lock net ", prevent that fish escape in the fence.
The installing of barrier net provided by the invention and use as follows:
If selection and the bottom surface of net position are leveled: it is suitable narrow unsuitable wide to establish gulf, storehouse, net place mouth, and section should be less, and water is more shallow, generally is not more than 10m, and the depth of water changes little; The bank base is solid, and the bottom is comparatively smooth, and substrate is preferably cohesive soil, is conducive to save material, and sets up and fixing barrier net; In the reservoir low water level, when water is more shallow, suitably arrangement proposes the falling zone at net place, infraclass engaging bottom the mouth section of gulf, storehouse when being convenient to adorn 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 section configuration figure processed (theoretical parameter) roughly, determine shape and the yardstick of block etting according to section configuration figure.In the making, the infraclass physical length should be than section long (loose) degree theoretical value ﹥ 15～20% on the block clothing; 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: after the barrier net etting is made and finished, mark, and respectively be 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; Install at the net place and preliminary fastening floating guiding principle in establishing; Lay the etting of the unassembled heavy stone of infraclass by boats and ships along floating guiding principle direction to the other end from establishing net gulf mouth embankment one end; Etting (headline) and floating guiding principle are linked; Arrangement, smooth-going infraclass, will " gabion " with the infraclass binding and compress infraclass; Reel on the bank is installed, with the fastening floating guiding principle of reel; Installing and fastening waist guiding principle are with the etting binding of waist guiding principle and corresponding site; The installing float.
Ship pass mouth night shift room is installed and the barrier net management: after barrier net installs, set up and fix the small log cabin night shift room at the float place of crossing the ship navigation channel, then the vertical rotating winch is mounted and fixed on the small log cabin night shift room, clump and the vertical rotating winch that will be fixed on the floating guiding principle with cable connect.During the breed, when boats and ships need pass through block, the small log cabin operator on duty unscrews the rotation steel ring of vertical rotating winch, put down floating guiding principle and etting that the ship pass mouth is reserved, make ship current, treat that boats and ships " are crossed net " after, screw the rotation steel ring of vertical rotating winch again, floating guiding principle and etting that pull-up ship pass mouth is reserved recover the original shape of block, prevent cultured fishes flight in the fence.
Small log cabin night shift room operator on duty cultures affairs and crosses the switching in ship navigation channel except being responsible for, and should make regular check on, removes contamination and nurse block, prevents from escaping accident generations such as fish.
