Description
Technical field
The invention belongs to marine life investigation field, particularly relate to a kind of network interface top that is positioned at single hull bottom laminar boom type trawlnet of ocean stratobios investigation sampling, in order to support the rod-like members of network interface transverse width.
Background technology
Single hull bottom laminar boom type trawlnet is to rely on the boom that is banded in the network interface headline to expand network interface, but there is following problem in traditional boom:
1, traditional boom mostly is wooden or bamboo, but former rod and mao bamboon pole are difficult to satisfy the requirement on intensity and the yardstick.Boom in the production is many between the length of 20.00-30.00m, and minimum also will be more than 8.00m, and so rod of length or bamboo pole are difficult to reach, and also are difficult to meet the requirements on intensity.So staggered extension of several rods commonly used or bamboo pole tied up to satisfy in producing, this causes whole boom very thick, heavy, not Portable belt transportation.
2, because the fast development of steel production in China ability, multiplex hot galvanized steel pipe is made boom in recent years, although changed thick, the heavy situation of boom of the wooden work of bamboo, because seawater has extremely strong corrosive property, reduced greatly the service life of steel pipe.And the problem of the long not Portable belt transportation of boom is still unresolved.Particularly flowing power, rapidity and the maneuverability requirement of the investigation work of ocean stratobios are very high, and the boom of Portable belt transportation does not meet the needs of investigation work.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, lightweight, intensity is high, be easy to carry the transportation the tubular trawlnet boom of disassembled glass-felt plastic.The present invention is that ocean, applicant Hebei province and aquatic science research institute are bearing public welfare industry (agricultural) scientific research special (200903005)-" investigation of yellow Bohai Sea living resources and maintenance technology research ", obtain through creative the effort, concrete technical scheme is as follows.

The tubular trawlnet boom of glass-felt plastic that the present invention is disassembled, the material of wherein said fork guiding principle positioning systems ring is corrosion-resistant steel.
The tubular trawlnet boom of the glass-felt plastic difference from prior art that the present invention is disassembled is that the tubular trawlnet boom of the disassembled glass-felt plastic of the present invention adopts some glass reinforced plastic pipes to form the boom body of rod, and the proportion of glass-reinforced plastic material is little, and intensity is high.Glass-felt plastic has outstanding decay resistance, and it neither can corrosion as many metals, also can be not rotten as bamboo and wood materials; Glass-felt plastic can be corroded by media such as oil, water hardly; The medium such as the acid of low concentration, alkali, salt and solution thereof there is preferably stability; The super performance of resisting atmosphere, seawater and microbial action is more arranged.Glass-felt plastic also has heat resistanceheat resistant, freeze proof and wear resisting property good, friction drag is little and the aging-resistant advantage.The trawlnet boom adopts some glass reinforced plastic pipes and glass-felt plastic connector bushing to assemble, and can carry out quick-detachment 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 glass-felt plastic of the present invention, adopt between glass reinforced plastic pipe and the glass-felt plastic connector bushing to be threaded, Assembly ﹠Disassembly is convenient, also is convenient to processing; Fork guiding principle positioning systems ring adopts hexagonal cylindrical head tightening screw in the metric system that dead ring is fixed on the optional position of glass reinforced plastic pipe, does not need speciality tool, is convenient to the location and adjusts.
Below in conjunction with accompanying drawing the tubular trawlnet boom of disassembled glass-felt plastic of the present invention is described further.
