Description

A flotation pontoon for mariculture

Technical Field

The utility model belongs to a mariculture device, relates to an appliance which is lifted upwards by utilizing buoyancy, in particular to a buoy which can automatically increase air pressure so as to prevent the pressure in seawater from being biased by water pressure.

Background

At present, shallow sea beach culture is widely promoted, and products such as oysters, laver and the like are mostly cultured in seawater. In mariculture, people need to prevent the aquaculture net cage from losing along with seawater drift or sinking into the sea bottom to be incapable of fishing, and the aquaculture net cage is often fixed by a floating body, so that the floating body can float in the seawater, and can also be fixed.

In recent years, many countries prohibit people from adopting products made of foam by issuing laws, and then people start to turn to the form of adopting other plastics which are made into a shape similar to a floating ball or a buoy to replace the original floating body.

Three relevant documents are given below to reveal the current development of the floating ball.

The Chinese patent application 200610164372.3 discloses a float with automatic buoyancy compensation, which comprises a hollow cavity 9, wherein the hollow cavity 9 is provided with an openable hole for convenient inflation and deflation, a connecting sealing element 10 is used for sealing the hole, and the hollow cavity 9 can play a role of enabling the float tail 2 to be positioned above and below the water surface.

Chinese utility model patent 201520833580.2 discloses an inflatable floating ball, which is used as an article for aquaculture and comprises a floating body 10 and a sealing cover 13, wherein the floating body 10 is provided with an inner plug 12 on a sealing opening 11, and an inflating nozzle 14 is arranged in the inner plug 12.

Chinese utility model patent 201720655849.1 discloses an aerify reinforcing structure that seals of floater again, it is equipped with interior stopper 2 on sealing port 1, is equipped with charging connector 3 in the interior stopper 2, and the top of interior stopper 2 forms shoulder hole 24 in charging connector 3's top, can set up sealed plug 5 in the shoulder hole 24 to form resealing to charging connector 3.

Therefore, in the prior art, people usually adopt a floating body, a hole is formed in the floating body, gas is filled into the floating body from the hole, and the hole is sealed by an inner plug or a valve.

Disclosure of Invention

The utility model aims at providing a flotation pontoon for mariculture, this flotation pontoon structure is simpler, and its preparation is also very fast, and the cost is also lower.

The purpose of the utility model is realized like this:

a float bowl for seawater culture is composed of an air bag made of plastics and a sealing cover made of plastics, and features that a sealing ring is arranged on the top surface of air bag port, a gas releaser is arranged in said air bag, and said air bag and sealing cover are fused together.

Preferably, in the above scheme, the gas releaser is dry ice or liquid chlorine dioxide or liquid nitrogen.

The buoy thus obtained will subsequently release gas at room temperature, which will fill the whole air chamber with a gas pressure that will enable the buoy to generate a partial pressure against the seawater in the seawater, preventing the buoy from deforming and affecting the use of the buoy due to the effect of a greater pressure.

Preferably, in the above scheme, the outer side wall of the airbag port is formed with a lower step, and a resealing weld ring is formed on the lower step, and the edge of the sealing cover extends downwards to form a welding convex ring, and the resealing weld ring and the welding convex ring are also welded together.

Thus, two sealing structures are formed between the sealing cover and the airbag, and the function of preventing gas from escaping can be more effectively achieved.

The buoy for mariculture is made of plastics, and even if the buoy is abandoned, the buoy is not easy to crush into small particles, so that the defect that the buoy made of foam is adopted as a floating body can be overcome, namely the defect that the floating body made of foam is easy to damage fishes because the floating body is abandoned and becomes small particles is overcome.

The utility model discloses a flotation pontoon for mariculture, owing to adopt the butt fusion to fuse sealing cover and gasbag integrative, and release gas by built-in gaseous releaser, can save and set up the pneumatic valve and aerify the operation, it is structural simpler and assemble more swiftly, be favorable to save material and cost of labor.

This a flotation pontoon for mariculture adopts twice seal structure between closing cap and the gasbag, utilizes sealed weld ring and reseal weld ring respectively with closing cap and butt fusion bulge loop butt fusion on different aspect, and its sealing performance is more excellent, can satisfy the continuous impact of sea water better and be difficult for producing gas leakage.

fig. 3 is a schematic view of the welded front closure cap and bladder of the buoy of fig. 1.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings:

referring to fig. 1, 2 and 3, the buoy for mariculture of the present embodiment comprises an air bag 1 made of plastic, a sealing cover 2 made of plastic and dry ice 3, wherein a connecting device 11 is formed on the sealing cover 1, a sealing weld ring 12 is formed on the top surface of the port of the air bag 1, a lower step is formed on the outer side wall of the port of the air bag 1, a resealing weld ring 13 is formed on the lower step, a welding convex ring 21 extends downwards along the edge of the sealing cover 2, the dry ice 3 is placed in the air bag 1, the air bag 1 and the sealing cover 2 are welded into a whole by the sealing weld ring 12 and the resealing weld ring 13 with the inner top surface of the sealing cover 2 and the welding convex ring 21 respectively, and the purpose of the present invention can be achieved.
