Description
Technical field
The invention belongs to the improvement of net cage for sea farming frame structure, is a kind of double-tube round lifting type net cage frame specifically.
Background technology
China's tradition is with the net cage wind wave resistance poor performance of plank, bamboo pole, steel-tube construction.The wind wave resistance measure of adopting at present both at home and abroad has two kinds, and the one, utilize the physical property of net cage frame material to come storm resisting, as utilize the premium properties etc. of high-strength polyethylene (HDPE) tubing; The 2nd, be the Wave Theory of exponential damping according to wave height with the increase of the depth of water, net cage is deposited to certain depth water layer under water.Above-mentioned two important technique measure that the aspect is the net cage wind wave resistance.At present both at home and abroad elevated live cage has four kinds of forms, and a kind of is the steel-tube construction sink and emerge type net cage of Japan, this net cage mainly be utilize several type inflatable floats fill draining and fixedly float and balance are controlled the lifting of net cage.Second kind is the dish-shaped net cage of U.S.'s development, and it utilizes gin pole inflatable drainage and water inlet exhaust to control the net cage lifting.The third is the two-tube circular net cage of high-strength polyethylene (HDPE) that Norway develops, and this net cage utilization realizes the lifting of net cage to net cage frame hollow circular tube inflatable drainage and water inlet exhaust.The 4th kind is to adopt water pump to realize lifting to framework water filling draining.The wind wave resistance elevated live cage that China uses has at present been applied for and the patented technology that obtains all adopts inflatable drainage and two processes of water inlet exhaust to control lifting, with above-mentioned four kinds belong to same technology category.But all there are shortcomings such as complicated operating process, the heavy power of time-consuming and net cage configuration are overweight, in case misoperation, the balance lifting difficulty.
Summary of the invention
The objective of the invention is problem at the prior art existence, a kind of double-tube round lifting type net cage frame is provided, has simple, convenient, quick, the steady reliable characteristics of lifting process, only adjust the overall buoyancy of net cage frame self with inflation and exhaust mode, can finish the descending operation of net cage, also can improve the ability of wind wave resistance.
The objective of the invention is to be achieved through the following technical solutions: a kind of double-tube round lifting type net cage frame, comprise: the master floats pipe, guardrail pipe, fence upright pipe and fills exhaust apparatus, it is characterized in that the floating pipe of described master comprises the floating round rubber gas tube of managing and being arranged on the outer ring of the circular HDPE master who is arranged on inner ring, and be connected as a single entity by connector, inflated rubber Guan Weiyi sealed whole body, on its tube wall, gas is housed and chews, fill the appendix that the intake and exhaust valve is housed in the exhaust apparatus and chew with gas and be connected.
Described inflated rubber tube wall comprises inner bag, hose lining, polyamide cord fabric and outer layer glue from inside to outside, and be processed into through over cure, its external diameter is consistent with the caliber of the floating pipe of HDPE master, at straight inflated rubber pipe closed at both ends place, extend one section band glue polyamide cord fabric respectively, cord fabric is through the cutting slivering and behind woollen yarn knitting, as inflated rubber pipe two ends connecting rope, after the two ends rope connected, inflated rubber is tubular to circularize.
Have at least 6 segmentation separation pipes that the equilibrium of the floating pipe of HDPE master is divided into mutual disconnected multistage chamber in the floating pipe of described circular HDPE master, comprise sealing airtight chamber that does not intake and the intake antrum that is provided with water inlet, and be provided with at interval.
There are two gas to chew on the described inflated rubber pipe,, connect a markfloat on the buoy rope that the other end of appendix connects by the end of a T joint to appendix.
The present invention compared with prior art has many advantages and good effect:
(1) traditional elevated live cage adopts come-up and the dive that realizes net cage to net cage frame buoyancy aid inflatable drainage and water inlet exhaust.And the present invention only adjusts the overall buoyancy of net cage frame self with inflation and exhaust, the intake and exhaust valve is connected on the inflator pump low inflation or opens the intake and exhaust valve and exits and can finish the descending operation of net cage, has omitted draining, water inlet process.Have simple, convenient characteristics efficiently.The rapid dive of net cage can improve the ability of resisting the high wind wave.
(2) compare with the net cage frame that the two-tube circle of HDPE that tradition adopts is made, circle adopts HDPE tubing in the present invention only, and the inflated rubber pipe is adopted in the outer ring, and price only is 1/3 of a HDPE tubing, and in light weight, is easy to carry and install.
(3) circle kept frame shape in the HDPE pipe of the present invention's employing was done, outer circle uses the inflated rubber pipe to adjust the overall buoyancy of net cage, have whole light characteristics, when marine red tide and pollution particularly take place, can shift fast, be dragged and dropped into safe marine site, improved the antipollution ability of cage culture, thereby guarantee cultured fishes safety.
(4) the present invention adopts the material of two kinds of unlike materials to make net cage frame, be rigidity and the flexibility of utilizing HDPE tubing, the deflection of bound rubber gas tube, bounce and endergonic physical characteristic are when having strengthened net cage and having kept afloat, as the capacity of anti-storm of floating cage.
(5) have at least 6 segmentation separation pipes that the equilibrium of the floating pipe of HDPE master is divided into mutual disconnected multistage chamber in the floating pipe of the present invention's circle HDPE master pipe, comprise sealing airtight chamber that does not intake and the intake antrum that is provided with water inlet, and be provided with at interval.Can reduce overweight heavy power and be equipped with, help controlling balance lifting.
(6) the present invention can charge and discharge the gas speed by valve control and control net cage dive and floating speed, and can tie the degree of depth of rope length control net cage sedimentation water layer by buffering.
