Description

Fish early resource drifting egg collecting device

Technical Field

The utility model relates to a fish early resource collection system field, concretely relates to fish early resource drift nature ovum collection system.

Background

Traditionally, a fusiform net is generally adopted for collecting drifting eggs of an early fish resource, and the fusiform net mainly comprises a net cover and a fry collecting barrel. The principle of use is that the collection point that has rivers puts into the aquatic at the collection point, utilizes the rope to fix it, and the roe enters into collection seedling bucket through the netting. The traditional collecting net can only collect in the river reach with slow water flow speed, and the net mouth and the net cage sink due to too high flow speed; various domestic wastes, branches and the like are contained in water, so that the collection net is easily blocked, the collection of eggs is affected, and the data is inaccurate. In addition, the net is very troublesome to get up, and a large amount of physical power needs to be consumed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a problem to prior art exists provides rubbish, labour saving and time saving's fish early resource drift nature ovum collection system in can in time clearing up the net, improves drift nature ovum collection efficiency, has reduced the impaired condition of roe.

In order to further realize the above purpose, the utility model adopts the following technical scheme: a fish early resource drifting egg collecting device comprises:

the net cage with the bracket comprises a bracket and a box-type net fixed on the bracket, wherein the box-type net is provided with a steel wire ring net inlet;

the front end of the fusiform netting is fixed on the semicircular net entrance bracket, the tail end of the fusiform netting is sewed by a steel wire ring, and the fusiform netting passes through the steel wire ring net entrance of the box-type netting;

the movable blocking net is sleeved in the fusiform netting, a net opening of the movable blocking net and a net opening of the fusiform netting are fixed with the net inlet support through binding bands, and the movable blocking net is used for blocking large garbage in water and slowing down water flow;

and the fixed blocking net is fixed at the middle section of the fusiform netting and is used for slowing down water flow for the second time.

Optionally, the closed PVC pipe and the bamboo chips are assembled into a semicircular mesh opening support through a tee.

Optionally, the support includes 4 vertical sealed stainless steel pipes and 4 horizontal sealed PVC pipes, and each sealed PVC pipe is fixed on two adjacent vertical sealed stainless steel pipes horizontally.

Furthermore, 8 top corners of the box-type netting are bound at the upper end and the lower end of the sealed stainless steel pipe by using binding bands.

Optionally, the center of the bottom of the movable blocking net is tied with a hemp rope, and the hemp rope is used for pulling the hemp rope connected with the bottom of the net outwards to take out the garbage.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. under the condition of rapid current, the movable blocking nets and the fixed blocking nets reduce the impact force of water flow and reduce the flow velocity in the net cage.

2. Under the condition of rapid flow, the movable blocking net can clean garbage in the net in time, so that the fish eggs and the garbage are prevented from being accumulated together, and sufficient space is provided for the fish eggs; in addition, the flow velocity in the net cage is greatly reduced by the movable blocking nets and the fixed blocking nets, and the condition that fish eggs are damaged is reduced.

3. The garbage in the net can be cleaned in time without getting up the net, time and labor are saved, and the drifting egg collecting efficiency is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail with reference to fig. 1-2.

A device for collecting drifting eggs of early fish resources is shown in figure 1, and comprises a main body, a fusiform net 1 and a net cage 8 with a bracket. The closed PVC pipe 2 and the bamboo chips 4 are assembled into a semicircular net inlet support through a tee joint 3, and the front end of the fusiform netting 1 is fixed on the semicircular net inlet support through a binding band; the net mouth of the pocket-type movable blocking net 7 is the same as that of the fusiform netting 1 in size, the pocket-type movable blocking net is sleeved in the fusiform netting 1, and a hemp rope is tied in the center of the net bottom of the movable blocking net 7, so that garbage can be cleaned conveniently; the net mouth of the movable blocking net 7 and the net mouth of the fusiform netting 1 are fixed with the net mouth bracket through the binding band; the fixed type barrier net 5 is fixed at the middle section of the fusiform net 1, and the tail end of the fusiform net 1 is sewed by a steel wire ring 6 and then passes through a steel wire ring net inlet 12. The movable blocking net 7 mainly functions in blocking large garbage in water, outwards pulls hemp ropes connected with the net bottom to take out the garbage, and is used for slowing down water flow. Fixed block 5 mainly functions in slowing down rivers for the second time, prevents that the seedling ovum from being destroyed by the rivers impact.

As shown in fig. 2, the net cage 8 with the bracket comprises 4 vertical sealed

stainless steel pipes

9, 4 horizontal sealed PVC pipes 10 and a box-type netting 11, each sealed PVC pipe 10 is horizontally fixed on two adjacent vertical sealed

stainless steel pipes

9, and 8 vertex angles of the box-type netting 11 are bound on the upper and lower ends of the sealed stainless steel pipes 9 by using a binding band for fixing.

The collecting device is put into water at a collecting point with water flow, and is fixed by a rope, and fish eggs enter a box-type net 11 with a support net cage 8 through a spindle-shaped net 1.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
