Description
Technical field
The utility model relates to a kind of trawlnet auxiliary traction instrument, relates in particular to energy-conservation trawlnet device.
Background technology
Trawlboat is by can divide two fishing boats that drag, singly drag and double as by mode of operation.Wherein, parallel the closing of two ships dragged 1 net of resisting and delaying during the two boat trawler, pair operation.The general job deck is at the middle front part of ship, superstructure in after, the cabin is rear, fish hold is front.20～40 meters of captains, 60～1000 kilowatts of main engine powers.Parallel shrimp trawl net relates to single ship shrimp trawlnet, needs to solve the technical matters of single trawler shrimping netting gear.The technical scheme of this utility model comprises net and web plate, it is characterized in that adopting skid that the net of two top same specifications is connected in parallel, the upper guiding principle of every top net, lower guiding principle hanging ratio are all in the 0.5-0.7 scope, sleeve net length and net gap perimeter ratio 22%-30%, body net length and net gap perimeter ratio 36%-40%, square length and net gap perimeter ratio 6%-10%, the force rate of drifting along example 30%-80%; The employing aspect ratio is 0.41 rectangle plane web plate; Skid becomes the spider shape, and drags iron at bottom welding, and the front portion is connected with drags the guiding principle fixing base, and the welding of spider rear portion is two fork guiding principle plates up and down.Yet it controls inconvenience, and efficient is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of novel structure, subtended angle to change energy-conservation trawlnet device rapid, efficient energy-saving for prior art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: energy-conservation trawlnet device, comprise the suspension board that is connected with trawlnet, and wherein: suspension board runs through to be provided with and can promote water body and make suspension board change the steering hardware of working direction; Suspension board also is connected with tow strap; The free end of tow strap can be connected and installed with the towboat of registration device; The suspension board top is connected with buoyancy aid, and on the buoyancy aid positioning antenna is installed.Registration device on the towboat is communicated by letter with positioning antenna, goes out the relative position of registration device and buoyancy aid by the triangle location Calculation, and then provides decision information for the running of steering hardware.Suspension board generally is positioned on the water surface, also can be as required by the water filling of buoyancy aid submerged.The running of steering hardware is according to the registration device positioning control, to change the direct of travel of suspension board in water, and then change connects the subtended angle of the tow strap of rear trawlnet, thereby the network interface of indirectly control trawlnet size and the direction of throwing the net, realize the purpose of a trawlnet of single ship operation, more energy-conservation, efficient is higher.
For optimizing technique scheme, Adopts measure also comprises: steering hardware is to run through main screw and the secondary screw propeller that can promote by ahead running and reversing control suspension board orientation that is arranged on the suspension board.The cooperation running of main screw and secondary screw propeller can change the lateral attitude of suspension board in water, and then changes the direct of travel of suspension board in water.Suspension board arranges when operation in pairs, main screw on the suspension board is sprayed water laterally, secondary screw propeller is sprayed water to the inside, so that in traveling process, suspension board is towards movement outside, and then two distances between the suspension board are strengthened along with the increasing of travel distance, so that the network interface of trawlnet progressively magnifies.
It is first that one end of suspension board is shaped with the plate that is acute angle; Suspension board has the hollow cavity structure, and is provided with the discharge port of advancing that can adjust displacement.One end of suspension board is shaped with the plate head that is acute angle can reduce resistance in the traveling process, and the hollow cavity structure that suspension board has changes buoyancy by the water filling draining.
In the use procedure, towboat connects two symmetrically arranged suspension boards through a pair of tow strap.Suspension board connects trawlnet through tow strap.When advancing, towboat drags suspension board, the locus that a pair of positioning antenna on each suspension board received and calculated registration device on suspension board and the towboat according to the triangle location.After obtaining the relative tertiary location of each suspension board and towboat, the telecommand of sending according to the operator increases or reduces two distances between the suspension board.For example, when needs reduce fast between two suspension boards apart from the time, the main screw on the suspension board and secondary screw propeller be water spray laterally simultaneously, promotes the inside quick travel of suspension board.Also can control main screw and secondary screw propeller towards different side spray water, form torsion, change the direct of travel of suspension board.
Because the energy-conservation trawlnet device of the utility model, adopted breeding wastewater at first after most of particulate matter is removed in the Separation of Solid and Liquid processing, behind the remaining dissolved organic matter of biological mode first treatment, ammonia nitrogen, nitrous acid nitrogen, remain in dissolved organic matter, ammonia nitrogen, nitrous acid nitrogen in the breeding wastewater through O3 contacted oxidation; Breeding wastewater after O3 contacted oxidation is processed is again through reducing with air aeration or removing to be dissolved in and process methods and the technological means such as strong oxide that produces because of O3 contacted oxidation in the breeding wastewater.Thereby, the utlity model has that novel structure, subtended angle change rapidly, the advantage of efficient energy-saving.
