Description
Technical field
The present invention relates to one and fish for device, what be specifically related to a kind of seining cultivation fishes for net.
Background technology
Ocean seining cultivation is a kind of mode of artificial aquaculture at present, and seining cultivation is divided into single variety to cultivate and multi items is raised together with; But no matter be single variety cultivation, or multi items raises together with the fish that all there are various different sizes, thus fishing in process at fishing net needs according to particular demands, selects the fishing net of different mesh size to fish for.And the mesh size of current fishing net is all specific standard usually, thus when fishing for the fish of different size specification, needing the fishing net adopting different mesh size, adopting the fishing net of large mesh when namely catching large fish, when catching small fish, adopting the fishing net of little mesh; This is for the fishing operation changed at any time, needs often to change netting gear and not only uses inconvenience, too increase the quantity of netting gear, cost.
Summary of the invention
The object of the invention is mesh size specification in order to overcome fishing net of the prior art specific, cannot regulate, the problem often changing netting gear is needed in fishing operation, there is provided a kind of mesh size of fishing net to regulate, and easy to operate seining cultivation fish for net.
Technical scheme of the present invention is:
A kind of seining cultivation fish for net, comprise fishing net body, described fishing net body is provided with the mesh adjusting device of the mesh size for regulating fishing net body, this mesh adjusting device comprises some airbag apparatus, and the airbag apparatus netting twine at each mesh edge of fishing net body is equipped with described at least one, described airbag apparatus comprises the mounting pipe be set on netting twine and the annular air-pocket bag be set in outside mounting pipe, and annular air-pocket bag is fixedly connected in mounting pipe, all annular air-pocket bags of described mesh adjusting device are interconnected by tube connector, have at least an annular air-pocket bag to be provided with in each annular air-pocket bag and fill exhaust nozzle.
Netting twine due to each mesh edge is equipped with at least one airbag apparatus, and the annular air-pocket bag of airbag apparatus is set on netting twine; Can, by the gas in inflation in annular air-pocket bag or release annular air-pocket bag, reach the object regulating mesh size, and it be easy to operate like this.
As preferably, in each annular air-pocket bag, be provided with balancing weight, and the gravity of balancing weight be more than or equal to annular air-pocket bag be full of air after buoyancy.Gravity due to balancing weight is more than or equal to annular air-pocket bag and is full of the buoyancy after air, and fishing net can be avoided like this to float, and ensures the normal use of fishing net.
As preferably, the middle part of fishing net body is provided with blanking port, and the below of fishing net body is provided with the blanking mesh bag of upper and lower both ends open, is provided with sealing gasbag in this blanking mesh bag, this sealing gasbag is connected with blanking mesh bag by connecting line, and sealing gasbag is provided with and fills exhaust nozzle; The upper port edge of described blanking mesh bag is connected with fishing net body, and blanking port is positioned at the upper port of blanking mesh bag, and the lower port edge of blanking mesh bag is provided with counterweight ring; After being full of air in sealing gasbag, the outer surface of sealing gasbag is close on blanking mesh bag, and the internal diameter sealing gasbag is greater than the internal diameter of counterweight ring.
After fishing net hauling, need the fish in fishing net to take out, and current fishing net is very inconvenient in this operating process; This programme just improves this problem, not affecting under fishing net gives and often wait upon imperial prerequisite, effectively addresses this problem.This programme, when fishing for, is full of air by sealing gasbag, and the outer surface of sealing gasbag is close on blanking mesh bag, thus shutoff blanking mesh bag.When fishing net hauling, the internal diameter due to the sealing gasbag being full of air is greater than the internal diameter of counterweight ring, and in a network process, sealing gasbag like this can not be extruded by fish, ensures that the fish in net can not come off.When after hauling, when needing the fish in fishing net to take out, only need discharge the gas in sealing gasbag, time fishing net in fish by the landing of blanking mesh bag, it is easy to operate.
As preferably, the gravity of counterweight ring is more than or equal in sealing gasbag the buoyancy after being full of air.
As preferably, annular air-pocket bag is cylindric.
As preferably, the mesh size of fishing net body is 50x50 millimeter.
As preferably, the sealike colour of fishing net body is 1.5-2.5 millimeter.
The invention has the beneficial effects as follows:
One, the mesh size with fishing net can regulate, and easy to operate feature.
Its two, after fishing net hauling, the fish in net can be taken out easily.
