The tubular trawlnet boom of fiberglass that the utility model is disassembled, the two ends of wherein said fiberglass joint sleeve are respectively arranged with female thread portion, described adjacent two mutually close ends of glass reinforced plastic pipe are provided with male thread portion, female thread portion on male thread portion on the described glass reinforced plastic pipe and the glass tube joint sleeve cooperates and is connected the closed at both ends of glass reinforced plastic pipe.It is airtight that shutoff can be carried out with same glass-reinforced plastic material in the two ends of glass reinforced plastic pipe, also can use different materials.
The tubular trawlnet boom of fiberglass that the utility model is disassembled, wherein each described fork guiding principle positioning systems ring comprises hexagonal socket cap trip bolt in dead ring, connecting ring and the metric system, described connecting ring is fixedly welded on the outside of dead ring, described dead ring is sleeved on the glass reinforced plastic pipe, hexagonal socket cap trip bolt radially is installed on the dead ring by the screwed hole on the dead ring in the described metric system, and in the metric system go deep into contacting with glass reinforced plastic pipe in the dead ring in the termination of hexagonal socket cap trip bolt.
The tubular trawlnet boom of fiberglass that the utility model is disassembled, the external diameter of wherein said glass reinforced plastic pipe is 50-80mm, thickness of pipe wall 6-10mm, every length is 1-2m.
The tubular trawlnet boom of fiberglass that the utility model is disassembled, the material of wherein said fork guiding principle positioning systems ring is stainless steel.
The tubular trawlnet boom of the fiberglass difference from prior art that the utility model is disassembled is that the tubular trawlnet boom of the disassembled fiberglass of the utility model adopts some glass reinforced plastic pipes to form the boom body of rod, and the proportion of glass-reinforced plastic material is little, the intensity height.Fiberglass has outstanding decay resistance, and it neither can corrosion as many metals, also can be not rotten as bamboo and wood materials; Fiberglass can be corroded by media such as oil, water hardly; Medium such as the acid of low concentration, alkali, salt and solution thereof there is stability preferably; The superperformance of resisting atmosphere, seawater and microbial action is more arranged.Fiberglass also has heat resistanceheat resistant, freeze proof and anti-wear performance good, frictional resistance is little and the aging-resistant advantage.The trawlnet boom adopts some glass reinforced plastic pipes and fiberglass joint sleeve to assemble, and can carry out fast quick-detach and the installation of random length, and is easy to carry and transport, is conducive to carrying out fast of ocean stratobios investigation work.
In the disassembled tubular trawlnet boom of fiberglass of the utility model, adopt between glass reinforced plastic pipe and the fiberglass joint sleeve to be threaded, installation and removal are convenient, also are convenient to processing; Fork guiding principle positioning systems ring adopts hexagonal socket cap trip bolt in the metric system that dead ring is fixed on the optional position of glass reinforced plastic pipe, does not need special tool(s), is convenient to the location and adjusts.
Below in conjunction with accompanying drawing the tubular trawlnet boom of disassembled fiberglass of the present utility model is described further.
