The invention aims to solve the problems in the prior art, and provides a flow avoiding device for large yellow croaker purse net culture, which has the characteristic of good use effect.
The purpose of the invention can be realized by the following technical scheme: the flow avoiding device in large yellow croaker purse net culture comprises anchor piles and is characterized in that a plurality of anchor piles are arranged at equal intervals, the bottoms of the anchor piles are inserted into a seabed, a main net is arranged between the front surfaces of every two adjacent anchor piles, a guide sleeve is sleeved on each anchor pile, a first net rope is fixedly connected between the top surfaces of every two adjacent guide sleeves, a vertical auxiliary net is arranged at the top of each first net rope, a second net rope is arranged at the top of each vertical auxiliary net, a plurality of floating blocks are arranged at the top of each second net rope at equal intervals, scraping plates are arranged on the bottom surfaces of the guide sleeves, a third net rope is arranged on one side, close to each other, of every two adjacent guide sleeves, and a transverse auxiliary net is arranged between every two third net ropes.
The cross section of the anchor pile is formed by splicing an arc and a rectangle, and the arc is an arc larger than one half.
The middle part of uide bushing is equipped with the recess, just the shape of recess is the same with the shape of the cross section of anchor pile.
The scraper blade sets up around the periphery of recess, the scraper blade is by the bottom surface slope of uide bushing downward setting, the one end that the scraper blade is close to the anchor pile apart from the distance that is less than the inner wall of recess apart from the anchor pile.
The horizontal auxiliary net is located behind the main net, the vertical auxiliary net is located behind the horizontal auxiliary net, and gaps between the horizontal auxiliary net and the main net and gaps between the vertical auxiliary net and the horizontal auxiliary net are smaller than the size of the large yellow croaker fry.
The main net and the vertical auxiliary net are overlapped all the time in the vertical direction.
The lower surface of the first net rope is fixed with balancing weights at equal intervals through ropes, and the sum of the gravity of the balancing weights is smaller than the sum of the buoyancy of the floating blocks.
Adopt this structure, squeeze into the anchor pile into the seabed and enclose into the breed area, put into the fry in the purse seine, the floating block is located the sea all the time, when the tide rises, the floating block drives second net line, vertical auxiliary net, first net line rebound, when the tide falls, the floating block moves down along with the sea water, under the action of gravity of balancing weight, the uide bushing moves down along the anchor pile to make vertical auxiliary net flush with the sea level all the time, prevent that the fry from escaping from the purse seine top along with the sea wave, horizontal auxiliary net prevents that the fry from escaping from the horizontal gap between major network and the vertical auxiliary net, excellent in use effect.
Compared with the prior art, the flow avoiding device in large yellow croaker purse net culture has the following advantages:
according to the invention, through the arrangement of the guide sleeve, the balancing weight and the floating block, the net head line on the vertical auxiliary net is always flush with the sea level, so that the fry is prevented from escaping from the top of the purse net in the tide rising process, and the salvage of floaters in the purse net is not influenced.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1-3, the current avoiding device in large yellow croaker purse net culture comprises anchor piles 1, wherein a plurality of anchor piles 1 are arranged at equal intervals, the bottoms of the anchor piles 1 are inserted into a seabed, a main net 2 is arranged between the front surfaces of two adjacent anchor piles 1, guide sleeves 8 are sleeved on the anchor piles 1, first net ropes 4 are fixedly connected between the top surfaces of the two adjacent guide sleeves 8, vertical auxiliary nets 3 are arranged at the tops of the first net ropes 4, second net ropes 6 are arranged at the tops of the vertical auxiliary nets 3, a plurality of floating blocks 7 are arranged at the tops of the second net ropes 6 at equal intervals, scraping plates 10 are arranged on the bottom surfaces of the guide sleeves 8, third net ropes 11 are arranged on one sides, close to each other, of the two adjacent guide sleeves 8, and a transverse auxiliary net 12 is arranged between the two third net ropes 11.
The cross section of anchor pile 1 is formed by arc and rectangle concatenation, and the arc is for being greater than half the circular arc, prevents that uide bushing 8 from reciprocating the in-process and breaking away from anchor pile 1.
The middle part of uide bushing 8 is equipped with recess 9, and the shape of recess 9 is the same with the shape of the cross section of anchor pile 1, and uide bushing 8 passes through recess 9 and slides along anchor pile 1.
