Description

A kind of HDPE self-tension flat bottom lift type anti-type net cage system and control method

Technical field:

The present invention relates to seawater cage culture facility field, especially relate to a kind of HDPE self-tension flat bottom lift type anti-type net cage system and control method.

Background technology:

Develop rapidly along with deep water wind wave resistance net cage facility and supporting technology, the core lifting technology of deep water elevated live cage not only will have resists the function that strong storm attacked and hid the red tide disaster, also to utilize its characteristics that sink to the seabed, can build a kind of suitable ecotope that is bordering on the seabed for the breed of left-eyed flounder; Therefore also gradually by improving wind wave resistance performance and anti-current ability, the special-purpose net cage direction that is fit to breed different cultivars fish towards multi-element ecology develops the research emphasis of deep water mesh cage.

In recent years, the breed upsurge of flounder fish had been risen in the northern China coastal area, and was in full swing in the mode of cage culture, the relay breed of net cage north and south, batch production and net cage relay breed, and economic benefit is rich.The special-purpose net cage of multi-functional high-tech that now is used for the left-eyed flounder breed both at home and abroad yet there are no report, the domestic net cage that is used for the left-eyed flounder breed now is wooden traditional floating raft type small-sized net cage of 5m * 5m mostly, it is characterized in that a steel underframe being set in the etting bottom, the etting bottom is tightened on the underframe, forms comparatively smooth flounder sole and perch platform.But wooden traditional floating raft type small-sized net cage capacity of anti-storm is poor, the steel construction underframe is unsuitable excessive because of weight and limit deformation, net cage again can not lifting, run into bigger stormy waves weather, very easily cause the breakage of net cage to run fish, therefore cause great economic loss to the raiser, developing a kind of net bottom, to perch the big elevation (over-and-under) type wind wave resistance net cage that is fit to the left-eyed flounder breeding environment again of platform area imperative.

The left-eyed flounder fish culture net cage is particularly suitable for the life habit characteristics that sandy sea bed upper base is dwelt in the shallow sea according to left-eyed flounder, and it is that net bottom is more smooth that its structure requires, environment is more stable, net bottom platform area is big, and culturing the depth of water should not be shallow excessively, the effect that preferably has the lift adjustment depth of water.

Summary of the invention:

The purpose of this invention is to provide a kind of HDPE self-tension flat bottom lift type anti-type net cage system and control method, it not only can culture the usefulness of left-eyed flounder, can also culture other swimming property fish uses, both had elevating function, can be separated into the large-area platform of culturing of multilayer again under water perches for the flounder sole, increase the space availability ratio of net cage, improved the cultured output and the economic benefit of net cage, had use value and positive social benefit widely.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the sphere shape net cage main frame 1 that it is constructed by HDPE tubing, high-strength fishing are formed with socketing rope 2, center gravity suspending hammer self balancing device 3, etting 4, HDPE pipe inflatable and exhaust mouth 5, high strength inflatable and exhaust flexible pipe 6, HDPE intake-discharge pipe mouth 7; HDPE tubing sphere main frame 1, high-strength fishing are with socketing rope 2, center gravity suspending hammer self balancing device 3, etting 4 formation net cage main bodys, with HDPE tubing and threeway and the welding of four-way connecting tube, utilize HDPE tubing elastic bending from tension force, socket platform at the bottom of the HDPE tubing sphere main frame 1 of the spherical shape that constitutes and the case by high-strength fishing with socketing rope 2; The suspending hammer rope of center gravity suspending hammer self balancing device 3 is hung by the sphere centre place and descend, by the net bottom plane socket the rope crosspoint, utilize the interconnection rope of the gravity effect net cage bottom surface of suspending hammer, maintenance net cage integral body is in poised state all the time; According to the height needs of net cage lifting water outlet, the length of following stay pipe leg at the bottom of the design HDPE net cage case is controlled the freeboard of whole net cage according to this; The net cage frame 1 of spherical shape carries out three-dimensional culture with etting 4 layering settings as required.

HDPE pipe inflatable and exhaust mouth 5, high strength inflatable and exhaust flexible pipe 6, HDPE intake-discharge pipe mouth 7 are formed lift control system, according to the exhaust or the inflation of breed demand manipulation high strength inflatable and exhaust flexible pipe 6, realize the elevating function of net cage.

Operation principle: the buoyancy that in seawater, utilizes the floating pipe of the HDPE cabin of sealing to provide, net cage is normally floated on the sea, open the exhaust valve venting, regulate the net cage buoyancy of net cage and the relation of gravity successively, when buoyancy during less than net cage gravity, the net cage sinking; Otherwise, in blast pipe, to inflate, floating pipe cabin buoyancy increases, and net cage come-up even part emerge; And can make part net cage casing emerge above as required.Center gravity plummet means is to utilize action of gravity to adjust the inclination that produces with balance net cage casing wind-engaging wave flow action and topple.

The present invention 1, make full use of the material behavior of HDPE bending pipes good springiness, construct a sphere shape and culture space frame; 2, center gravity suspending hammer self balancing device; 3, the most casings of net cage can rise from the water surface; 4, utilize constructing net bottom from tension force and culturing platform of HDPE bending, need not to be provided with steel net cage underframe.

The present invention has following beneficial effect: design principle is reasonable, the simple and clear easily row of structure, the big layer stereo of platform is cultured, saves the space, is increased the benefit, can sink under water or rest on different water layers, flexible, the attack that can hide typhoon and red tide but cheap, easy operating, the anti-fluidity of cage structure system can be cultured good, under water, can culture different types of fish, have wide range of applications.
