Description
Technical field
The utility model relates to arrive fish production technical field, it is related specifically to a kind of fixed fish ovum seedling acquisition netting gear
Device.
Background technique
During fish early stage resource investigation, it is raw to do fish to need to be acquired the ovum seedling of rivers Mesichthyes identification
State research.Fish ovum seedling acquisition equipment routinely is mostly fixed against ship and carrys out operation, spends biggish manpower and cost, and
The more dangerously steep uneven area of some topographies, streamflow is rapid, and in the case where being furnished with gravel along the river, the acquisition of fish ovum seedling is set
It is standby to be difficult to dispose, extreme difficulties are brought to investigation work, largely limit the development of investigation work.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of devices to fix fish ovum seedling acquisition netting gear.It can solve
Certainly in topography precipitous terrain, it is furnished in the uneven situation of gravel along the river and makes proper arrangements fish ovum seedling acquisition netting gear and energy Xiang Jiangzhong
The device of extension.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of device of fixed fish ovum seedling acquisition netting gear, comprising: center base, supporting element, support rod, winding roll, volume
Wire coil shaft, preceding extension rod, middle extension rod, rear extension rod, spring, aft hook and front hook, described device fill in center base
There are supporting element and support rod, winding roll is housed, after being respectively provided at the top of support rod in the spiral dish axle of the middle and upper part of support rod
Extension rod and aft hook, the end sleeve of rear extension rod are equipped with middle extension rod, and the end sleeve of middle extension rod is equipped with preceding extension rod, preceding to prolong
The front of stock is equipped with front hook.
The spring with the decorative pearl on top of an official cap, preceding extension rod and middle extension are respectively provided in middle extension rod and rear extension rod in described device
Aperture is provided on bar.
Rocking bar is housed, spiral disk center is provided with axis hole, and winding roll passes through axis hole and support rod on the winding roll of described device
On spiral dish axle be connected.
Compared with prior art, the good effect of the utility model are as follows:
1, the device of fixed fish ovum seedling acquisition netting gear, also can preferably dispose fish ovum along the river by firm banking
Seedling acquires netting gear；
2, the device controls the distance that fish ovum seedling acquires netting gear by extension rod, more easily to acquire required fish
Ovum seedling；
3, the device substantially reduces the cost of fish early stage resource investigation, improves the working efficiency of investigation.

Specific embodiment
Clear, complete description further is carried out to the technical solution of the utility model with reference to the accompanying drawing.
Referring to attached drawing 1-4, the device is assembled first, center base 1 is crux, and 1 four sides of center base is
Embedded, each section of supporting element 2 is embedded composition pedestal, and 1 center position of center base has a hole, inside there is screw thread and support rod
3 are attached；Support rod 3 is a solid steel tube, and lower end has the screw thread hole for being threaded through center base 1 to be connected, middle part edge
There is spiral dish axle 5, winding roll 4 is connected on support rod 3 by spiral dish axle 5, and lateral ends are fixed by nut, on being set in
The joystick 6 in face shakes winding roll 4, and there are screw thread hole and hook 11 in the upper end of support rod 3, passes through screw thread hole and rear extends
Bar 9 connects, and hook 11 is connected to winding roll 4 for hanging the rope of fish ovum seedling acquisition netting gear；Entire extension rod is divided into three
Section, is made of preceding extension rod 7, middle extension rod 8 and rear extension rod 9, and three sections of extension rods are hollow steel pipe, and preceding extension rod 7 is in
Extension rod 8 is scalable, and is respectively arranged with 10 pressable of spring of a protrusion thereon.And it is distributed on middle extension rod 8 and rear extension rod 9
There are three equidistant apertures, 10 protrusion of spring is corresponding with the aperture on preceding extension rod 7 and middle extension rod 8 when stretching, for controlling
Development length processed.Meanwhile preceding 7 front end of extension rod acquires netting gear for hanging fish ovum seedling equipped with hook 12.
Specific work process is as follows: the device each section being connected, is placed in along the river, fish ovum seedling acquisition netting gear is passed through
In on the front hook 12 of preceding extension rod 7, rope is pulled to aft hook 11 and lies on winding roll 4 rope suspensions, extension rod 7 before stretching
Required length is arrived with middle extension rod 8, netting gear is made not have Yu Shuizhong, after a period of time, the rocking bar 6 in spiral dish axle 5 is shaken, receives
Netting gear pull-up is collected the fish-egg in netting gear and fry by contracting rope.
