Special adjustable and environment-friendly support rod for deep sea aquiculture and fabrication method of support rod

Abstract

The invention discloses a special adjustable and environment-friendly support rod for deep sea aquiculture, which comprises a rod body, wherein the rod body is provided with a columnar hollow core; an external wall of the rod body is polygonal; an internal wall of the rod body is circular; the upper part of the rod body is fixedly provided with a stop web curtain bar by fastening clamps; a mud stop tray limited by a fastening clamp is arranged on the rod body; a connection rope is connected between the mud stop tray and the fastening clamp for limiting the mud stop tray; a fixed empennage is arranged at the bottom of the rod body, and comprises an empennage seat fixed on the rod body; and a plurality of empennage sheets are symmetrically arranged on the empennage seat. The invention further discloses a fabrication material and a fabrication method of the support rod. The support rod is very reasonable in structural design, large in support load, and high in wind / wave resistance, and does not break or crack; skin of the support rod is smooth and delicate, so that an arm cannot be scratched, and the rope cannot be abraded during operation; shells, plankton and algae in an ocean can be prevented from adhering to the support rod; and the support rod is free from peeling and residue falling, and is higher in corrosion resistance, long in service life, green, environment-friendly, shock-resistant, and ageing-resistant.

Description

technical field [0001] The invention relates to an aquaculture pole, in particular to an adjustable and environment-friendly deep-sea aquaculture special pole; the invention also relates to a preparation method of the adjustable and environment-friendly deep-sea aquaculture special pole. Background technique [0002] Inserting rod type seaweed farming technology is the best among the existing farming models. After years of accumulated experience, the farmers have continuously optimized the combination and explored the most practical production method. This method can produce high-quality, high-quality seaweed. Yield of laver. However, as the pollution of the coastal waters continues to increase, the nutrient content in the seawater continues to decrease, and the demand for land reclamation and construction in the country continues to expand, forcing laver cultivation to develop in the deep sea. The circular hollow fiberglass pultrusion pipes disclosed in the prior art are u...

Problems solved by technology

[0003] 1. Not strong enough to meet the needs of deep-sea farming

The length of the circular hollow tube support rod is generally only about 14 meters. If it is longer, it will bend as a whole when it is vertical and cannot support any load. Due to its structural form and process formula, even if it is thicker and thicker Even if it exceeds 15 meters, there will still be overall bending and other phenomena, so it cannot be used

[0004] 2. The inner and outer skin of the strut lacks a protective layer

The original design of the hollow rod body of the round tube is soaked in seawater, blown by wind, beaten by waves, and exposed to the sun. Since there is no isolation protective layer, it is very easy to accelerate degradation and aging. One of the components, calcium carbonate, is easily deteriorated in seawater to form calcium chloride and Unstable carbonic acid will form small holes and gaps on the surface of the rod body, allowing seawater to enter the inside of the rod body. After a vicious cycle, the surface of the rod body is more prone to peeling and slag. After the glass fiber is soaked in water, the strength decreases, and more broken fibers appear. Falling into sea water, wrapped in laver, eventually rendering the laver inedible

It has been proved by practice that after one year of use, the poles will peel off and the glass fibers will be exposed. Some users' palms have been stabbed by the glass fibers during use.

[0005] 3. The knot fixing piece, limit tray, and spiral piece of the pole are all hand-laid up. They are glued and fixed on the pole body. They cannot be adjusted in time according to the depth of the water and the thickness of the mud layer. After use, it is very unreasonable and even becomes a burden.

[0006] (1) The height of the hanging net curtain cannot be adjusted according to the production needs due to the two knotted fixing pieces. In addition, the hand lay-up process is solidified, and the surface is not smooth, especially rough, and the rope and the net curtain are often worn out. Therefore, Not practical

[0007] (2) The limit tray is also fixed and cannot be adjusted according to the thickness of the mud layer in each breeding area

[0009] 4. Due to the insufficient height of the poles, the net curtains are often dropped and torn, and the normal drying cannot be carried out, resulting in poor or no laver harvest.

[0010] 5. Since the support rod has no base, it is easy to shift, which makes the hanging curtain angle increase and cannot be used, and the insertion rod must be relocated
