It is simple that fixation cylinder operation is set, but because cylinder is fixed on the river bed, so be subjected to the restriction of permanent plant length, generally can only be fixed on the offshore zone.Especially when carrying out scientific research activity, cylinder to be taken out the ovum amount of wherein adopting of calculating every the set time.Such operation is labor intensive very often, and operating personnel's operation of will paddling has certain danger.

The advantage of adopting ovum by the ship linked network is a conveniently moving, can carry out any position in the river, and shortcoming is that cost is higher, receives in the network process to damage fish-egg, often can not obtain than accurate data when carrying out the fish-egg statistics.

Prior art two kinds of method defectives commonly used in gathering the fish-egg process are, can not continued operations, need additional energy source, and the operating cost height, operating personnel have certain danger, and it is vulnerable to be gathered fish-egg.Adopting ovum equipment generally speaking is inconvenient to move.

Summary of the invention

The purpose of this utility model is to provide a kind of simplicity of design, and low cost is moved continuously, gathers the water fish ovum automatically and focuses on the device of egg-collecting box.

A kind of automatic collection fish-egg device that promotes by waterpower of the utility model comprises: floating platform, egg-collecting box, skimming ladle, mistake oviduct, pillar, rotating shaft, baffle plate, four-way pipe, water conservancy diversion hyoplastron;

Above-mentioned skimming ladle becomes axial symmetry to arrange, is fixed in the rotating shaft, and symmetry axis is rotating shaft, skimming ladle when sinking under the water opening towards the downstream;

Above-mentioned two baffle plates become axial symmetry to arrange that symmetry axis is rotating shaft, and baffle plane and skimming ladle plane intersect vertically, and are fixed in the rotating shaft;

Above-mentioned oviduct excessively is fixed on skimming ladle near in the middle of the bottom of rotating shaft one side, and skimming ladle communicates with the mistake oviduct;

Above-mentioned egg-collecting box comprises framework and etting, and etting is fixed on the framework;

Above-mentioned skimming ladle comprises spoon of the waterproof end and permeable skimming ladle, and spoon of the waterproof end is wrapped in the permeable skimming ladle outside, and permeable skimming ladle can be selected the hard skimming ladle of self-supporting for use, also can select soft etting external pillared stent for use as the steel wire skimming ladle;

Above-mentioned rotating shaft is the stereoplasm tube of hollow, can be pvc pipe, steel pipe or other stereoplasm tubes;

Above-mentioned oviduct excessively and rotating shaft are communicated with by four-way pipe;

Above-mentioned four-way pipe center is provided with the water conservancy diversion hyoplastron;

Above-mentioned water conservancy diversion hyoplastron be fixed on four-way pipe inside with the separated hard plate of four-way pipe, its partitioning scheme is for when four-way pipe becomes vertical state, the water conservancy diversion hyoplastron from left to bottom right or from upper right to the lower-left, four-way pipe is equally divided into not connected two parts.

The utility model has following beneficial effect:

1, simplicity of design, cheap, be convenient to mobile operating, job area is wide;

2, rationally utilize current to promote, need not additional energy source, long-time running continuously, operating cost is cheap, and fish-egg health is gathered in protection;

3, operating personnel's job safety on floating platform;

When 4, carrying out the science sampling, method is unified, and the data reliability that obtains is higher.

Embodiment

Following embodiment is used to illustrate the utility model, but is not used for limiting scope of the present utility model.

Shown in Fig. 1,4,5, a kind of automatic collection fish-egg device that promotes by waterpower of the utility model comprises floating platform 1, egg-collecting box 2, skimming ladle 3, crosses oviduct 4, pillar 5, rotating shaft 6, baffle plate 7, four-way pipe 8, water conservancy diversion hyoplastron 9;

3 one-tenth axial symmetry of described skimming ladle arrange that be fixed in the rotating shaft 6, symmetry axis is rotating shaft 6, skimming ladle 3 when sinking under the water opening towards the downstream;

7 one-tenth axial symmetry of described two baffle plates arrange that symmetry axis is rotating shaft 6, and baffle plate 7 planes and skimming ladle 3 planes intersect vertically, and are fixed in the rotating shaft 6;

Described oviduct 4 excessively is fixed on skimming ladle 3 near in the middle of the bottoms of rotating shaft 6 one sides, and skimming ladle 3 communicates with mistake oviduct 4;

As shown in Figure 2, described egg-collecting box 2 comprises framework 2a and etting 2b, and etting 2b is fixed on the framework 2a;

As shown in Figure 6, described skimming ladle 3 comprises waterproof end spoon 3a and permeable skimming ladle 3b, and waterproof end spoon 3a is wrapped in the permeable skimming ladle 3b outside, and permeable skimming ladle is the steel wire skimming ladle;

As shown in Figure 3, described rotating shaft 6 is the pvc pipe of hollow, and above-mentioned oviduct 4 excessively and rotating shaft 6 are communicated with by four-way pipe 8, and four-way pipe 8 centers are provided with water conservancy diversion hyoplastron 9;
