Description
Technical field
The invention belongs to fish-catching apparatus technical field, more particularly to a kind of big field ditch fish-catching apparatus and its installation method.
Background technology
Field ditch is seen everywhere in rural area, is typically categorized into small field ditch, middle field ditch and big field ditch.Wherein, small field ditch is more
For water storage inside farmland and draining, middle field ditch is used to accept the water of small field ditch, and big field ditch upstream connect small field ditch or in
Field ditch and downstream are directly connected to inland river and are otherwise known as ultimate gutter, how V-shaped.After Summer Heavy Rainfall, big field ditch accepts small field
Rainwater in ditch and middle field ditch, when the rainwater in big field ditch the more stores the more more, formation basin imports inland river at last.At this point, fish by
Like inverse trip in its nature, the shoal of fish in inland river, which will swim to upstream, to be converged in big field ditch, then how to capture these shoals of fish
Currently, being had not been reported to the device fished in big field ditch, there are many inland river fish-catching apparatus, but the landforms of big field ditch
Feature and the geomorphic feature in inland river have prodigious difference：Much smaller than inland river of the big field ditch of one；Secondly the side slope of big field ditch is usual
It has planted crops or has been covered with weeds, caused inland river fish-catching apparatus to be not particularly suited for fishing in big field ditch, grabbed if manually caught by force
Crops is necessarily damaged, or even damages ditch slope soil texture so as to cause serious soil erosion.In addition, the shoal of fish in big field ditch is only
Have after Summer Heavy Rainfall just can inverse trip and on, the short time survives in crop field ditch waters, suitable with the reduction of water level in big field ditch
Flow swims go back to inland river, if with fixed inland river fish-catching apparatus, fishing number is by the how many limitation of rainfall, if made or have much ado
Installation inland river fish-catching apparatus will lose more than gain.So seek a kind of fish-catching apparatus for being more applicable in big field ditch and taking into account ease for operation,
It is worth thinking deeply about.
Invention content
Goal of the invention：The purpose of the present invention is in view of the above-mentioned problems, proposing a kind of big field ditch fish-catching apparatus, effectively fishing is big
The shoal of fish in field ditch realizes the science and convenience of rainy season installation fish-catching apparatus, limes marginis is destroyed when avoiding manually fishing by force
Crops and soil texture.
Technical solution：In order to achieve the above-mentioned object of the invention, the present invention provides a kind of big field ditch fish-catching apparatus, the fishing
Device included water barrier, cross bar, fishing net and mesh bag, and the water barrier bottom open semicircle shape of crossing encircles mouth, and is fixed on the cross
It was covered in the bottom that half on water barrier is covered in big field ditch in tiltedly paving formula, the fishing net half on bar, the mesh bag is fixed
It is located on the fishing net behind arch mouth, the water inlet edge of heavy net stone fixed net, iron bores the corner of fixed net.
Preferably, described to cross that water barrier is identical by thickness length, giantreed that material is hard is worked out, giantreed and giantreed it
Between gap should not be too large also unsuitable too small, excessive gap is unable to hold out fishing net, and too small gap discharge capacity is too poor, giantreed seam
Gap 2mm is advisable.It crosses water barrier bottom and opens arch mouth, arch mouth is diametrically the semi-circular shape of 0.4m-0.5m, crosses water barrier and passes through bolt
Be fixed on cross bar, cross bar and it is corresponding cross water barrier bolt point can according to actual needs trepanning it is several, special bolt point
It was located at the focus point of water barrier and its point symmetrical above and below, the big little makings of the size matching pin hole of bolt, bolt and bolt
Hole needs slitless connection, to the stability for ensureing cross bar with crossing water barrier.Water barrier was freely adjusted according to the height of water level
Bolt point position and tiltedly paving angle, when water level is higher, cross water barrier oblique paving angle be 30 degree -45 degree, reduction fish fills
The water flow pressure born and impulse force are set, when water level is relatively low, the angle for crossing water barrier is 65 degree of -80 degree, improves the expansion of fishing net
Degree.
Preferably, cross bar is that the hollow steel pipe of several a length of x is spliced by articulation, the outer diameter 4cm internal diameters of steel pipe
3cm, wherein articulation are by nut, cloud cluster and flush three parts and form, and can facilitate installing and dismounting steel pipe, make according to demand arbitrary
The cross bar of length is applicable in any type of big field ditch.Sharp-featured square steel tube is selected at the both ends of cross bar, prevents cross bar from sliding,
Keep fish-catching apparatus more firm.
Preferably, the area coverage of fishing net can be as large as possible, can be by both sides when for relatively small big field ditch
Fishing net is curled in both sides, and the color of fishing net is blue, preferably fishing net can be hidden in flow, the mesh size of fishing net
For 2mm, the shoal of fish is avoided to escape from the mesh for being covered in flow bottom fishing net, the centre position opening diameter of fishing net is 0.4-
0.5m semicircles were to adapt to the arch mouth of water barrier for fixing mesh bag.The edge of fishing net influent side is fixed with heavy net stone, it is ensured that
Fishing net is seamless close to flow bottom, and the shoal of fish is avoided to slip away from fishing net bottom.The corner of fishing net influent side is bored with iron fix respectively, is used
In stablizing fish-catching apparatus, fishing equipment is avoided to be washed away by rapid stream.
Preferably, the color of mesh bag is identical as fishing net color, mesh size 20mm, for capturing the adult shoal of fish, keeps away
Exempt to capture juvenile fish and influence the ecological balance.It is embedded in iron ring at 1/3L, 2/3L of mesh bag (L is mesh bag length) respectively, for branch
Mesh bag is supportted, is being cinch cord at away from arch mouth 1/6L, when the shoal of fish is swum into mesh bag tail portion, is heaving out cinch cord, the shoal of fish is avoided to migrate from arch
Mouth is escaped.
The present invention also provides a kind of methods of installation fish-catching apparatus, including：
A selects the giantreed that thickness is identical with length, material is hard, and giantreed was woven into water barrier, is used in compilation process
2mm cardboards control the gap between giantreed and giantreed.
B measures the width of big field ditch, cross bar is made in the connection of several steel movable pipe joints, corner angle point are selected at the both ends of cross bar
Bright square steel tube, and be across between big field ditch.
C is punched on crossing water barrier and cross bar respectively with punching device, while being made and being matched suitable bolt with aperture.
D is tiltedly layered on water barrier is crossed on cross bar, and the angle tiltedly spread can be determined according to water level in big field ditch and flow rate of water flow, be used
Bolt fixes water barrier with cross bar.
E makes fishing mesh bag, iron ring is embedded at 1/3L, 2/3L of mesh bag (L is mesh bag length) respectively, away from arch mouth 1/
It is cinch cord at 6L.
F sews mesh bag on fishing net, and mesh bag stretching arch mouth was placed in the rear portion of water barrier and is stretched.
The half of fishing net was laid on water barrier by g, the other half is laid in the bottom of big field ditch, and fishing is fixed with heavy net stone
The quadrangle of fixed net is bored on the inlet side edge of net with iron.
Advantageous effect：
The present invention provides a kind of big field ditch fish-catching apparatus, effectively captures the shoal of fish for flowing back to trip in big field ditch downstream, realizes
The science and convenience of fish-catching apparatus, effectively prevent manually fishing the harmful effect brought by force.
