Abstract
The utility model relates to an upper and lower separator for an offshore buoyant raft breeding cage and changes the upper and lower separator of the net cage to be steering wheel-shaped for satisfying a new technique that the fitting demand is met for a net cage underwater automatic cleaning device (an annular net scraper). The technical scheme includes that: the upper and lower separator of the net cage is made of plastics with certain elasticity through one-step injection or compression molding to form steering wheel shape, according to traditional method, the upper and lower separator and other net cage middle separator are assembled to form a net cage with steering wheel-shaped upper and lower separator. The ring part diameter of the steering wheel is equal to the diameter of the net cage middle separator, the steering handle is a sheet-type bar, the radius of the steering handle from the top end to the steering core is more than the inner ring radius of the annular net scraper to more than 80 mm. The steering wheel-shaped net cage separator can prevent the annular net scraper nested on the net cage from separating from the net cage upwards and downwards, and the steering handle can be artificially bent to make the annular net scraper conveniently be nested on the net cage through separators. The steering wheel-shaped net cage separator has the beneficial effects that the separator is labor saving, economical, has simple operation and easy operation.
Description
Affiliated technical field
The utility model relates to a kind of lower clapboard of going up on the marine suspended longline farming cylinder mould, is that dividing plate about the existing circular cylinder mould is transformed into steering wheel shape, to satisfy a kind of new technology---and cylinder mould is the supporting needs of automatic flushing device (the annular net is scraped) under water.
Background technology
China marine site is vast, and the mariculture industry development is swift and violent, and cultured output occupies first of the world, and wherein shellfish culture accounts for more than 70% of gross yield, and what extensively adopt at present is buoyancy raft net cage culture.Marine shellfish is cultured the research of preventing and kill off of stained thing on the cylinder mould and is carried out for many years, and domestic and international many papers all have report, are to cause one of shellfish undergrowth and main causes of death attached to the stained thing on the cylinder mould.How effectively to prevent and kill off the stained thing of culturing on the cylinder mould and become one of important subject of culture fishery.
" a kind of device that cylinder mould is cleaned under water automatically " comes out at present, other has multinomial patents of invention such as " a kind of method and apparatus that cylinder mould is cleaned automatically " to be disclosed under water, these patented technologies have effectively solved the problem that stained thing is prevented and kill off on the mariculture cylinder mould, concrete grammar all is with a kind of exterminating device---the annular net is scraped and is sleeved on the cylinder mould, " and making it all can not break away from cylinder mould up and down ".Lower clapboard can not directly satisfy above-mentioned specification requirement on the existing cylinder mould, need on lower clapboard on the cylinder mould, to add in addition a cover annex and scrape the disengaging cylinder mould to prevent the annular net, these annexes have plenty of to intersect with iron wire and pass lower clapboard on the cylinder mould, having plenty of the large size cylinder mould dividing plate that will scrape internal diameter greater than the annular net is fixed on the cylinder mould on the lower clapboard with cotton rope, make the annular net scrape the specification requirement that all can not break away from cylinder mould up and down to reach, these methods all exist take a lot of work, take material, the loaded down with trivial details and cost of operation is crossed problems such as height.
Summary of the invention
For overcome taking a lot of work of adding in addition on lower clapboard on the cylinder mould that the annex method exists, consumptive material, operation is loaded down with trivial details and the too high problem of cost, the utility model provides a kind of steering wheel shape cylinder mould dividing plate, it can stop effectively that the annular net scrapes, and makes it all can not break away from cylinder mould up and down.
The technical solution adopted in the utility model is: dividing plate about the circular cylinder mould is scraped the size size by the annular net be transformed into steering wheel shape, the annulus section diameter of steering wheel is identical with the diameter of cylinder mould central dividing plate.Steering handle is the sheet bar shaped, the interior ring radius that scrape greater than the annular net to the radius of the rudder heart on its top is more than 80 millimeters, the annular net is scraped up and down all can not be broken away from cylinder mould, but can be under artificial effect with the bending respectively of sheet bar shaped steering handle, the annular net scraped to be sleeved on the cylinder mould or from cylinder mould easily take out, behind the complete operation, steering handle can recover straightened condition automatically.
The beneficial effects of the utility model are; Saving of labor, economy, simple in structure, processing ease.
Description of drawings
Fig. 1 is the utility model steering wheel shape cylinder mould dividing plate front view.
Fig. 2 is Figure 1A-A cutaway view Amplified image.
Embodiment
Selection has certain flexible plastics, presses disposable injection moulding of planform or the compression molding of Fig. 1, by conventional method itself and etting is assembled into the cylinder mould that lower clapboard is a steering wheel shape with other cylinder mould central dividing plate.
When installing or taking out the annular net and scrape, sheet bar shaped steering handle bending respectively with steering wheel shape dividing plate, the annular net scraped to be contained on the cylinder mould or from cylinder mould by steering wheel shape diaphragm housing ring take out, behind the complete operation, sheet bar shaped steering handle can recover straightened condition automatically and break away from cylinder mould under water to stop the annular net to be scraped.
Claims (1)
1. steering wheel shape cylinder mould dividing plate, steering wheel annulus section diameter is identical with the diameter of cylinder mould central dividing plate, steering handle is the sheet bar shaped, and the interior ring radius that scrape greater than the annular net to the radius of the rudder heart on its top is more than 80 millimeters, and it is characterized in that: this cylinder mould dividing plate is a steering wheel shape.
