Aquiculture stay bar and production method thereof

Abstract

The invention relates to an aquiculture stay bar, which comprises a bar body. The aquiculture stay bar is characterized in that the bar body is a hollow bar body; a spirally-arranged spiral piece is fixedly arranged at the lower part of the bar body; a limiting tray is fixedly arranged on the bar body above the spiral piece; and a rope knot fixing piece is fixedly arranged at the upper part of the bar body. The invention further discloses a production method of the aquiculture stay bar. The production method is characterized in that the aquiculture stay bar is produced by extruding and forming through a die, taking m-benzene type unsaturated polyester resin and the like as base materials, taking alkali-free twistless glass fiber roving as a radial framework, taking a polyester composite felt as a weft covered felt and taking hemming felts as a weft sandwich felt and a weft inner felt. The aquiculture stay bar has the advantages of reasonable structure, firmness in support, no floating, lightness in inserting into mud, capability of rotating, high firmness, light weight, high elasticity, strength which is 3-5 times that of a bamboo pole, low possibility of breaking off, favorable acid and alkali and salt resistance, insolubility, favorable temperature resistance, ageing resistance, no pollution, capable of being repaired and long service life.

Description

technical field [0001] The invention relates to equipment for aquaculture, in particular to an aquaculture pole, and also relates to a preparation method of the aquaculture pole. Background technique [0002] Inserting rod-type laver culture technology is developed by absorbing the respective advantages of semi-floating and full-floating culture methods, combined with the characteristics of my country's cultured sea areas. It is flexible and changeable, and its breeding is highly controllable. Its advantages are very obvious. It can advance the harvesting time by one month and increase the yield by an average of about 700 kilograms per mu. To obtain such a good harvest and high-quality laver, the pole is the most critical Yes, it can be said that the performance of the pole determines whether the cultured laver can be successfully harvested or not, and determines whether the industry can continue and develop. [0003] Existing moso bamboo struts have few advantages and man...

Problems solved by technology

[0006] 2. Bamboo poles have insufficient strength, low density, and poor wind and wave resistance

Whenever there is bad weather, thousands of bamboo poles are pulled up or broken by the wind and waves, and then large pieces of laver net curtains are rolled up by the wind and waves, resulting in no harvest and huge economic losses.

[0007] 3. The moso bamboo that is broken off every year drifts on the sea everywhere, affecting the cultivation of other seafood, affecting the smooth flow of waterways, and increasing the difficulty of management of maritime affairs and other departments, which is very harmful

A large amount of seabed garbage is accumulated over time, which seriously pollutes the sea area for cultivation, making it very difficult to insert the rods in the second year, seriously affecting the layout of the laver cultivation field every year, and passing ships cannot drive, which is very dangerous
