The material of PE42tex6 × 3, etting are equipped with enough floats and guarantee that headline floats on the water surface, and bottom is equipped with enough sinkers and guarantees
Infraclass is sunk to the bottom, and upper infraclass uses the rope of PE Ф 3cm, and the fence net of 2 sides is arranged in "eight" shape.Every side wall net can be divided into when setting
2 sections, length is followed successively by 90m and 30m, with rise/angle of ebb tide water (flow) direction is respectively 30 ° and 15 °, formed 111.6m ×
109.0m fence net setting area.Along fence net direction every the fixed fence net etting of 10m steel pipe, fence net long 120m, high 10m when laying；
Wherein body net can be considered the continuity of fence net, the selection of unilateral etting and mounting means and fence net in the side etting structure of front
Unanimously, netting hanging is having a size of 26.0m × 10.0m, and horizontal hanging ratio takes 0.707 in assembly, mesh size 3.0cm, etting
Using the material of PE42tex6 × 3.The funnel structure at rear portion is composed of 3 monomer funnel structures.Outside single funnel structure
It is supported by rigid frame, the size of outer framework is 3.0m × 3.3m × 6.0m, leakage stainless steel welded prefabricated using diameter Ф 2cm
Bucket is the rectangular entrance of 3.0m × 3.3m in its fluoran stream surface, makes the round exit of a diameter 1.0m at rear portion.Use size of mesh
Assembly production Criny after the mesh sheet of 2.0cm tenses, etting use the material of PE42tex6 × 3.The 2 side etting of front of body net is laid
When along body net direction fix a steel pipe every 10.0m piling, for hanging and fixing fence net, body net and fence net junction width
It is set as 6.0m, and is gradually narrowed along body net, until Criny front is contracted to 3.0m width, the side the 6.0m net at body net rear portion is not
It shrinks；Wherein fish gathering monitoring case, is uncovered cuboid net cage, net cage frame drawingdimension be 3.0m × 3.0m ×
10.0m.Monitoring case etting selection PE42tex8 × 3, mesh size 2.0cm, horizontal hanging ratio takes 0.707 (square mesh in assembly
Using).In fluoran stream surface, entrance of the sheepshank having a size of 1.0m is installed from bottom 1.0m, 4.3m and 7.6m equipotential.On the inside of monitoring case
Criny export top, it is each a chip size be installed be greater than outlet size cover mesh sheet.
The installation of netting gear:
The production of frame, iron anchor, iron chains, monitoring case etc. installation production in advance on the coast.Anchor line and monitoring case connecting rope
Can be customized in producer according to design specification, anchor line can be connected thereto before iron anchor transports when marine integrated installation.
Sinker is connect with floating ball with rope on auxiliary canoe, the length of connecting rope is close with the depth of water at anchor dispensing, throws
Lower sinker is as combination net cage anchor position point.According to the layout and anchor position spacing of the fixed mooring system of net cage, it is repeated in the above step
Suddenly, anchor position point of 18 sinkers as combination monitoring case is launched in order.According to positioning float position and 18 anchor position points on the water surface
Position coordinates are corrected, and make floating ball in the equal marshalling of vertical, horizontal.Floating ball can will finally be positioned in position, that is, conduct of the water surface
Throw reference placement position when anchor.
Iron anchor weight is 0.5 ton, selects hoisting weight to hang an iron anchor every time for 5 tons or more loop wheel machines, iron anchor
It sinks into water.It should select to flow combined pressure difference direction installation exercise with the wind, system installation is fixed in selection downwind when slack tide
Operation, in fair current to installation exercise when windage is little.It is dragged in the region of fixed system with installation ship by cabinet frame is monitored,
Net cage frame is fixed with anchor line, and is hauled.Fixed system after the installation is completed, according to frame in the state of the water surface, passes through anchor
The elastic of chain is adjusted, and keeps it no neat in water surface distribution.
According to entrance of Changjiang River landform and hydrologic regime, river mouth subtidal zone biological monitoring net is laid along Yangtze River channel, two groups of fence nets
It is respectively facing upstream and downstream, is on the whole in east-west direction, can satisfy the monitoring of fluctuation damp phase.Fence net is from shallow water to depth
Water extends laying, and the fence net of 2 sides is arranged in "eight" shape.In order to guarantee the attracting effect of fence net, when setting, every side wall net can divide
Be 2 sections, length is followed successively by 90m and 30m, with rise/angle of ebb tide water (flow) direction is respectively 30 ° and 15 °, form width 11.6m, length
9.0m fence net setting area.Fence net setting is steep after first delaying, so that induction individual enters body net.The 2 side etting cloth of front of body net
If when along body net direction every 10.0m piling fix a steel pipe, for hanging and fixing fence net, body net and fence net junction are wide
Degree is set as 6.0m, and gradually narrows along body net: 30.m is shunk along 20.0m, until Criny front is contracted to 3.0m width, body
The side the 6.0m net at net rear portion is not shunk.Body net rear portion length be the region 6.0m in, it is depending on the specific depth of water that 3 funnels are vertical
Arrangement is installed on body net final stage, and 2 side of entrance of fluoran stream surface is supervised uniformly around side etting, aft exit and fish gathering is sewn in
The entrance being accordingly arranged on measuring tank fluoran stream surface is connected；Such Criny, which is played, leads into collection for all individuals into body net
Fish monitoring case, and the individual of energy entry deterrence fish gathering monitoring case returns to escape.The etting of fish gathering monitoring case side is arranged and fence net
It is identical with body net side net etting setting method, cabinet is formed by 3.0m × 3.0m piling steel pipe when laying, and hangs fixed etting.
This netting gear is suitble to entrance of Changjiang River Special Geographic natural environment, combines the widely used networking in entrance of Changjiang River, throws the net and insert
The advantages of fishing style of net, can capture various aquatiles using tidal action and flow action.Estuarine organism monitoring net
Minimum mesh be 2.0cm, it is more enough to monitor mandarin sturgeon children sturgeon, while the injury such as will not cause death to other young fishs.
River mouth subtidal zone biological monitoring net will not destroy local ecological resources, nothing pollution-free to natural ecological environment while monitoring
It destroys.It rationally, not will cause escaping and missing for fish, greatly protect with good induction and fish-gathering effect, network interface design
The accuracy of monitoring result is demonstrate,proved.Its in the future protection of resources and ecosystem monitoring play the role of great, be conducive to
The development of Monitoring of Resource and Environment in the future.
According to the utility model method, applicant carries out and completes the inside proof test of netting gear.Launch installation effect in scene
Fruit is good, and netting gear working condition is normal.It is demonstrated experimentally that this netting gear can be suitable for Hekou Area waters, it can be to monitoring object
Play the role of induction to concentrate, can achieve the effect that monitoring resource in the case where not destroying living resources.
It is the preferred embodiment of the utility model above, those of ordinary skill in the art can also carry out respectively on this basis
Kind of transformation improves, and under the premise of not departing from the utility model total design, this reality is all should belong in this transformation or improvement
Within the scope of novel be claimed.
