Problems solved by technology

Changing the net of the breeding net is easy to cause an emergency response of the fish in the net, leading to the escape of the cultured fish, affecting the normal growth and development of the cultured fish, and affecting the cost and benefit of the net breeding
During the development of aquaculture nets, many technical problems that have not been solved for a long time have been exposed, such as the problem of broken and lodging of the net column piles, the direct contact and continuous wear between the net column piles and their attached organisms and the net clothing, Poor overall wind, wave and current resistance of the enclosure, poor exchange of water inside and outside the enclosure, fish escaping from the bottom of the enclosure, and high consumption of raw materials for the enclosure have seriously affected the safety of enclosure farming.

Embodiment Construction

[0008] The best way to implement the present invention is illustrated below in conjunction with the accompanying drawings:

[0009] The invention adopts reinforced concrete column, channel steel, nylon rod, PVC coated canvas, ultra-high-strength rope, marine antifouling paint, high-strength polyethylene monofilament (hereinafter referred to as HSPE monofilament), and the column pile adopts "reinforced concrete column pier + Reinforced concrete column + column pile arm frame + column pile traction rope + column pile hanging grid" combined structure; first use a twisting machine (such as NX30 / 90 large steel twisting machine) to twist 72 wires with a diameter of 0.2mm The HSPE monofilament with a strength of 7.34g / D is processed into a HSPE monofilament rope yarn with a twist of 66 twists / meter, and then 155 HSPE monofilament rope yarns are processed in the same way; ) Processing 52 pieces of HSPE monofilament rope yarn into one HSPE monofilament rope strand according to the spec...

Abstract

The invention relates to an upright pile for surrounding a cultivation net. The upright pile utilizes a reinforced concrete upright column and is characterized by utilizing a combined structure consisting of a reinforced concrete upright pier, the reinforced concrete upright column, upright pile arm frames, an upright pile pulling rope and an upright pile hanging net force headrope; as to the reinforced concrete upright column, the outer diameter is 50cm, the length is 21m and the wall thickness is 10cm; anti-fouling paint for ships is painted on the outer surface of the reinforced concrete column, and an upright pier is arranged at the upper end of the reinforced concrete upright column; cylindrical nylon rods are utilized as the upright pile arm frames; a high-strength polyethylene monofilament rope passes through a PVC (polyvinyl chloride) coating canvas pipe to form the upright pile hanging net force headrope; the upright pile hanging net force headrope and the upright pile arm frames are fixed; the upright pile arm frames are arranged at intervals of 2.5m from a 2.5m-position from the top end of the reinforced concrete upright column; an ultra-high-strength rope is taken as the upright pile pulling rope for connecting the reinforced concrete upright column, the upright pile hanging net force headrope and the upright pile arm frames, all connection parts are bound sequentially, and the upright pile for surrounding the cultivation net is obtained.

Description

technical field [0001] The invention relates to the technical field of aquaculture net enclosures, in particular to column piles for aquaculture net enclosures. Background technique [0002] The column pile of the breeding net fence is an important part of the breeding net fence. It plays an important role in supporting the net clothing, stabilizing the formation of the net fence and warning ships in the breeding net fence project. Due to different habits or regions, net fence post piles are also called net fence poles or net fence posts. Existing aquaculture net column piles use single structures such as bamboo poles or small reinforced concrete columns with rough surfaces, and the failure of the net enclosure column piles under bad weather often occurs. The existing breeding net enclosure directly binds the net clothing on the rough reinforced concrete small column pile. Net fence posts, net fence clothes and net fence ropes are very easy to grow attached organisms (such...
