Description
Technical field:
The utility model relates to the fish culture net cage technical equipment, mainly refers to the into silt particle device of preventing of net cage frame buoyancy standpipe bottom.
Background technology:
A kind of advanced person's net cage for sea farming with self-balancing sink-float function; Its framework is formed with its upper and lower side horizontal trombone slide structure that is connected to each other by many vertical buoyancy standpipes; Its top of buoyancy standpipe is provided with air inlet and exhaust valve; Its bottom has water-inflow and drain valve, and fills exhaust apparatus and constitutes net cage self-balancing sink-float system jointly.There is a defective in existing this system, i.e. the spool under shed of buoyancy standpipe bottom water-inflow and drain valve is so when net cage is in the seabed and need floats; The seabed silt particle easily with seawater under shed gets into the buoyancy standpipe; And become silted up knot in it, and finally cause the spool under shed to stop up, lose into draining and net cage self-balancing sink-float function; If the unimpeded obstruction that has that each buoyancy standpipe has then very easily produces rollover damage accident again in the sinking floating net cage process.
Summary of the invention:
The goal of the invention of the utility model; Be to provide a kind of novel net cage frame buoyancy standpipe bottom to prevent into silt particle device; Can effectively avoid the seabed silt particle to get in the buoyancy standpipe; Guarantee that buoyancy standpipe bottom water-inflow and drain valve central through hole is unimpeded, the control function is sensitive reliable, guarantees net cage self-balancing sink-float safety and steady.
The technical scheme of this invention is, into silt particle device is prevented in novel net cage frame buoyancy standpipe bottom, and its shape is the upper shed cylindrical shell; Its end opening has elastic cover plate, is a plurality of perpendicular ribs of radial even distribution in the entire body, and perpendicular rib outer rim and cylinder inboard wall join; Perpendicular rib inner edge joins with the collar nut outer wall that is in vertical centre position in the cylindrical shell, and perpendicular rib is in nut and tilts to cylinder inboard wall with edge within the top, and perpendicular rib is in nut and joins with edge within the lower part and base plate outer wall; Perpendicular rib constitutes vertical through holes and the cross through hole of opening on base plate to each other; The central through hole of chamber and water-inflow and drain valve spool links within cross through hole and the nut, and water-inflow and drain valve spool lower part is connected with nut thread, and top is bell mouth shape; Be mounted on buoyancy standpipe bottom center opening part, water-inflow and drain valve spool end face is turbination.
This device is threaded with the spool lower part of buoyancy standpipe bottom water-inflow and drain valve through collar nut in the cylindrical shell and is fixed in buoyancy standpipe bottom, at this moment, will have the bigger draining slit 15 of advancing between cylindrical shell upper edge of this device and the buoyancy standpipe bottom outer rim.
This device of sinking floating net cage process prevents that into the principle of silt particle is:
When the net cage that floated sank, the gas in the buoyancy standpipe was constantly discharged, and seawater is prevented the into slit 15 entering cylindrical shells between the silt particle device cylindrical shell upper edge and buoyancy standpipe bottom outer rim via this; Central through hole 9 via opening 6 within vertical through holes 5, cross through hole 6, the cross through hole 6 ' entering water-inflow and drain valve spool 7; Get into chamber within the buoyancy standpipe 11 through central through hole 9,10 in chamber inner sealing ball floats on the water level surface of continuous rising, so; Sink down into sea bottom surface until net cage; Always by 12 sealings of rubber cover plate, silt particle advances less than in the buoyancy standpipe at the end opening of whole sinking process cylindrical shell 1, has guaranteed that the buoyancy riser bottom do not have sediment deposition; Make the water-inflow and drain valve central through hole keep unimpeded, make net cage self-balancing sink-float function normal reliable.When net cage floats; Constantly inflate with aerating device in the buoyancy standpipe; Water in the buoyancy standpipe will and prevent that into the silt particle device is constantly gone out by pressure through the bottom water-inflow and drain valve; The path is to be forced out via central through hole of water-inflow and drain valve spool 79 and cross through hole 6; And then divide two parts to be gone out outside the cylindrical shell by pressure, a part is through the external (not shown) of cylindrical shell end opening rubber cover plate 12 peripheral openings expelling tubes that is pressed off, and partly is that slit 15 expelling tubes between vertical through holes 5, cylindrical shell upper edge and buoyancy standpipe bottom outer rim are external in addition.
As above analyze, this device design science is reasonable, and working stability is reliable, can guarantee to advance not go silt particle in the buoyancy standpipe, and water-inflow and drain valve is not blocked, and the work that makes it is sensitive normal, guarantees that net cage self-balancing sink-float function-stable is reliable.
