Abstract

The utility model relates to a steering wheel-shaped positioning ring for an offshore buoyant raft breeding cage and aims to satisfy a new technique that the fitting positioning is realized for a net cage underwater automatic cleaning device (an annular net scraper). The technical scheme includes that: the steering wheel-shaped positioning ring is composed of an annular steering ring and a sheet-type bar steering handle, the inner diameter of the steering ring is less than the diameter of the upper and lower separators of the net cage to 20-30 mm, the radius from the top end of the steering handle to the steering center is more than the inner ring radius of the annular net scraper to more than 80 mm, the upper and lower separator of the net cage are bent to be nested into the steering wheel-shaped positioning ring respectively, and then sheet-type bar steering handle is respectively bent, the annular net scraper is nested on the net cage (or removed from the net cage), when the operation is finished, the steering handle can automatically recover to flat state for preventing the annular net scraper from separating from the underwater net cage. The steering wheel-shaped positioning ring can be made of plastics with certain elasticity through one-step injection or compression molding. The utility model has the beneficial effects that the positioning ring is labor and time saving, has convenient operation and reduces the cost.

Description

A kind of steering wheel shape locating ring

Affiliated technical field

The utility model relates to attachment exterminating device on the marine suspended longline farming cylinder mould---and the supporting location that the annular net is scraped is scraped in seawater the annular net that is sleeved on the cylinder mould and all can not be broken away from cylinder mould up and down.

Background technology

China marine site is vast, and mariculture industry develops 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, and only the area, Dalian has platform raft of cultivation up to a million, and the breed cylinder mould is hundreds of millions of.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, have plenty of to be fixed on the cylinder mould with cotton rope greater than the large size cylinder mould dividing plate that the annular net is scraped internal diameter and make the annular net scrape the specification requirement that all can not break away from cylinder mould up and down to reach on the lower clapboard, these methods all exist takes a lot of work, takes material, the loaded down with trivial details and too high problem of cost of operation.

Summary of the invention

For taking a lot of work of overcoming that annexes such as adding iron wire and large size cylinder mould dividing plate on lower clapboard on the cylinder mould in addition 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 locating ring, it can stop the annular net to scrape the disengaging cylinder mould.

The technical solution adopted in the utility model is: form steering wheel shape locating ring by annular rudder circle and sheet bar shaped steering handle, the internal diameter of rudder circle is gone up the diameter 20-30 millimeter of lower clapboard less than the net dragon, the ring radius was more than 80 millimeters in scraped greater than the annular net to the radius of the rudder heart on the steering handle top, lower clapboard on the cylinder mould enclosed be inserted in steering wheel shape locating ring respectively after curved, again with the bending respectively of sheet bar shaped steering handle, the annular net scraped be sleeved on the cylinder mould (or take out from cylinder mould), behind the complete operation, steering handle can recover straightened condition automatically and break away from cylinder mould under water to stop the annular net to be scraped.

The beneficial effects of the utility model are: the saving of labor, save time, easy to operate, reduce cost.

Description of drawings

Fig. 1 is the front view and the local cutaway view Amplified image of the utility model steering wheel shape locating ring.

Embodiment

Selection has certain flexible plastics, press disposable injection moulding of planform or the compression molding of Fig. 1, broken section enlarged drawing among Fig. 1 represents that this steering wheel shape locating ring has reinforcement, the size of its reinforcement can be decided according to the stressed size that the annular net is scraped in seawater, to guarantee effectively to stop the annular net to scrape the disengaging cylinder mould under water.Steering wheel shape locating ring is sleeved on the cylinder mould behind the lower clapboard, lower clapboard can play the axial location effect to it on the cylinder mould, make itself can not break away from cylinder mould, this moment, etting always was in tensioned state under the action of gravity of material culture, and steering wheel shape locating ring is played the radial location effect.

Claims

1. steering wheel shape locating ring, form by annular rudder circle and sheet bar shaped steering handle, the internal diameter of rudder circle is less than the diameter 20-30 millimeter of lower clapboard on the cylinder mould, and the ring radius was more than 80 millimeters in scraped greater than the annular net to the radius of the rudder heart on the steering handle top, and it is characterized in that: this locating ring is a steering wheel shape.
