Abstract
The invention discloses a buoyant vertical pipe inflating dewatering vortex-resistant device for a cultivation net cage and relates to a submerged device for a submergible cultivation net cage. The buoyant vertical pipe inflating dewatering vortex-resistant device comprises a buoyant vertical pipe, a pipe bottom water inflow and drain hole and a floating ball in the pipe. A hollow permeable column is arranged in a pipe cavity of the buoyant vertical pipe, a plurality of permeable through holes are distributed in a column wall of the permeable column, the bottom of a permeable cavity in the permeable column is in a cone bowl shape, the center of the bottom of the permeable cavity is provided with a water inflow and drain opening to be communicated with the water inflow and drain hole at the bottom of the buoyant vertical pipe, the floating ball is arranged in the permeable cavity, the permeable column is covered with a counter-flow cover with a lower opening, and a water passing gap is reserved between the lower opening edge of the counter-flow cover and the bottom of the buoyant vertical pipe. The buoyant vertical pipe inflating dewatering vortex-resistant device has the advantages when water in the pipe enters the counter-flow cover in the reverse direction through the outside of the counter-flow cover and the water passing gap at the lower opening edge of the counter-flow cover and enters the permeable cavity through the permeable through holes in the column wall of the permeable column, mutual collision offset is caused, the water in the permeable cavity is in a turbulence state, and rotational flow and vortex cannot be formed, so that the net cage can be stably and safely submerged in a balanced mode.
Description
Technical field:
But the present invention relates to the submerged floating fish culture net cage, but relate generally to the submerging and surfacing device of submerged floating fish culture net cage, particularly feeding/discharging device at the bottom of the pipe of submerged floating fish culture net cage buoyancy standpipe.
Background technology:
But existing submerged floating fish culture net cage buoyancy standpipe, its pipe top has air inlet-and-exhaust device, and the pipe bottom has drainage arrangement.Pipe jacking exhaust apparatus comprises conical cavity Ding, center porting; Pipe end feeding/discharging device comprises that boring bowl-shape Qiang Di, center advances discharge outlet; Also comprise the tube chamber inner float ball.When net cage needs dive, the buoyancy standpipe carries out the pressure release water inlet, and seawater advances discharge outlet through the pipe end and enters in pipe, and ball float constantly floats with water level, finally blocks pipe jacking exhaust outlet.When net cage need float while rising, the buoyancy standpipe carries out inflatable drainage, and compressed air is filled with in pipe by pipe jacking exhaust outlet, and in manage, water advances the discharge outlet pressure through the pipe end and goes out, in inflation will be managed water drained after, ball float blocks manages the end and advances discharge outlet.In above-mentioned net cage floating inflatable drainage process, find that in tube chamber, water easily forms eddy current in lower row's process, revolves nest under the effect of inflation pressure, the pipe inner float ball easily is threaded into funnel-form Xuan Wo center, so, when water is also drained in pipe, ball float is threaded into and revolves the nest centre bottom and will advance discharge outlet and block, cause in managing and can not continue draining, water is arranged endless, water, the inflation floating that this will affect net cage, also easily cause floating uneven sometimes, and the net cage overthrow accident occurs.
Summary of the invention:
The present invention's purpose, be to provide a kind of fish culture net cage buoyancy standpipe inflatable drainage vortex eliminator, and it can effectively avoid the formation of eddy current in buoyancy standpipe inflation floating-upward process pipe, and in pipe, water can drain smoothly fully, make net cage steadily, the floating of balance, safety.
Within the present invention, hold: a kind of fish culture net cage buoyancy standpipe inflatable drainage vortex eliminator, comprise buoyancy standpipe 1, osculum 7 is advanced at the pipe end, pipe inner float ball 5, feature is, be provided with hollow permeable post 2 in buoyancy standpipe tube chamber, the post jamb of permeable post is distributed with a plurality of permeable through holes 4, it is bowl-shape that 3 its ends of permeable chamber in permeable post, be cone, its center have into discharge outlet 7 ', advance discharge outlet 7 ' with advance osculum 7 at the bottom of buoyancy standpipe pipe and communicate, be provided with ball float 5 in permeable chamber 3, permeable post 2 is covered with the anti-stream cover 8 of under shed, peristoma 8 under anti-stream cover ' and buoyancy standpipe pipe at the bottom of between there is water space 9.
Further preferably, the permeable chamber 3 of described permeable post is provided with 1 to 3 in the present invention, respectively is provided with a ball float in each permeable chamber.
The beneficial effect that the present invention produces:
When buoyancy standpipe inflatable drainage, water in buoyancy standpipe pipe under the effect of inflation pressure by permeable post counter flow cover outer through anti-stream cover hypostome 8 ' and buoyancy standpipe pipe at the bottom of between mistake water space 9, oppositely enter that permeable post is counter to flow in cover, enter in permeable post through the set all a plurality of permeable holes 4 of permeable post jamb, then advance discharge outlet 7 ' efflux to advancing osculum 7 at the bottom of buoyancy standpipe pipe by bottom, permeable chamber.When the water outside permeable post enters in permeable chamber by all a plurality of permeable holes, to produce collision negative function mutually, make permeable chamber Nei Shui be turbulent condition, can not form eddy flow, eddy current, can not form and revolve nest, ball float 5 will unanimously float on the water surface, decline with water level descends, and can not be screwed into too early at the bottom of chamber, will not advance discharge outlet 7 ' block, so, can make to manage interior water and drain fully, net cage balance, steady, safe snorkeling.
