Technical field
The present invention relates to one and fish for device, be specifically related to a kind of floating type expanded metals fishing gear of seining cultivation.
Background technology
Ocean seining cultivation is the artificial aquaculture mode of one in fishery cultivating field.The work of fishing for of traditional ocean seining cultivation is a very heavy manual labor job, because netting gear is heavy, all compares effort when shedding and receive net, impact fishing efficiency.
On the other hand, seining cultivation is divided into single variety cultivation and multi items to raise 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 first object of the present invention is large in order to overcome labor intensity of fishing for of the prior art, the problem of impact fishing efficiency, the floating type expanded metals fishing gear of the seining cultivation of fishing efficiency that provides a kind of easy to operate, effectively can reduce labour intensity, improves.
Another object of the present invention be the 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, a kind of mesh size of fishing net is provided to regulate, and the floating type expanded metals fishing gear of easy to operate seining cultivation.
Technical scheme of the present invention is:
A kind of floating type expanded metals fishing gear of seining cultivation, comprise fishing net body and the first air pump, described fishing net body comprises gusset net and the spacer screen of annular, lower limb and the spacer screen edge of described gusset net are connected as a single entity, the top edge of gusset net is provided with a circle air bag, and the inflation inlet of described first air pump is connected with air bag by gas ducting, 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.
The floating type expanded metals fishing gear of the seining cultivation of this programme can be inflated in air bag by the first air pump in a network process, make the top edge of gusset net float up on the water surface, receive fish speed fast, easy to operate, effectively labour intensity be can reduce, fishing net frequency of utilization and fishing efficiency improved.
On the other hand, the 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, be provided with blanking port in the middle part of spacer screen, the below of spacer screen is provided with the blanking mesh bag of upper and lower both ends open, is provided with sealing gasbag in this blanking mesh bag, and 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 spacer screen, 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, 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 lower limb of gusset net is provided with some nets pendant.
As preferably, annular air-pocket bag is cylindric.
As preferably, the mesh size of fishing net body is 45x45 millimeter.
As preferably, the sealike colour of fishing net body is 2 millimeters.
The invention has the beneficial effects as follows:
One, has easy to operate, effectively can reduce labour intensity, improve the feature of fishing efficiency.
Its two, the mesh size with fishing net can regulate, and easy to operate feature.
Its three, after fishing net hauling, the fish in net can be taken out easily.
