Description
Technical field
The utility model relates to a kind of river fry harvester, is specifically related to the young postlarva harvester of the many water layers in a kind of river.
Background technology
The investigation of young postlarva is an important content of aquatic products and aquatile subject, when young postlarva is investigated, need different offshore distances sample with different water layers in the river.The bank sampling will be gathered net usually and fixedly gathered; And in the river zone line when sampling since the restriction of the depth of water just must pull netting gear and realize by boats and ships; This just makes sampling process become very complicated; Also be not easy to regulate and gather net water depth of living in, be difficult to collect the fry in the target waters, each sampled point is understood respectively because of the inconsistent error that increases investigation result greatly of time; Therefore, will exist during sampling to the high dependency of boats and ships and to gathering probabilistic problem of the net degree of depth of living in.
The utility model content
The purpose of the utility model provides the young postlarva harvester of the many water layers in a kind of river; To the boats and ships high dependency and to gather the net degree of depth of living in uncertain, make the problem of the fry that is difficult to collect the target waters when having in the river to solve that different offshore distances are sampled with different water layers now.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: it is cone barrel that the said fry of the utility model is gathered net; The big opening end that fry is gathered net is fixed on the head rope, and the osculum end that fry is gathered net connects collection seedling bucket one end, and the other end of collection seedling bucket is equipped with valve; One end of nettle is connected on the head rope; The end of restricting that suspends is connected with flotation gear, and the suspend other end of rope and the other end of nettle tie up on the static line jointly, and an end of static line is connected with fixture.
The utlity model has following beneficial effect: the utility model can to young postlarva in the river different offshore distances sample with different water layers; It is cone barrel that fry in the harvester is gathered net; Can the effective collection fry; It is 28-35 that fry is gathered the order number of netting, and this order is counted the made fry collection net of scope and both avoided fry from fry collection net, to escape, and it is excessive to prevent that again fry collection net from receiving impact force of water flow.The osculum end that fry is gathered net connects collection seedling bucket one end, and the other end that collects the seedling bucket is equipped with valve, thereby the effect of collection seedling bucket is with the flow direction fry to be got in the collection seedling bucket to store fry, and the effect of valve is when collecting work finishes, conveniently to take out fry.Regulate the rope that suspends and conveniently to control the depth of implements that fry is gathered net; This work mainly be on the water with survey tool measure to suspend rope length and be fixed on the nettle; Again whole young postlarva harvester is put into water, an end of the rope that suspends is connected with flotation gear, has accomplished the collecting work by different depth waters, bottom to top layer thereby can make fry collection net be in suspended state; Fixture is positioned in the selected waters, has played the fixation of fry being gathered net.The utility model can be a plurality of uses to throw in diverse locations and different water layers are set simultaneously to be gathered, the error of having avoided the result of multi-site single acquisition to cause because of the time is inconsistent.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model, and Fig. 2 is the left view that the fry of the utility model is gathered net.
Embodiment
Embodiment one: combine Fig. 1 that this embodiment is described; The young postlarva harvester of the many water layers in the river of this embodiment comprises the fry collection net 1 and the head rope 2; It is characterized in that the young postlarva harvester of the many water layers in said river also comprises flotation gear 3, valve 4, nettle 5, the rope 6 that suspends, collection seedling bucket 7, static line 8 and fixture 9, it is cone barrel that said fry is gathered net 1, and the big opening end that fry is gathered net 1 is fixed on the head rope 2; The osculum end that fry is gathered net 1 connects collection seedling bucket 7 one ends; The other end of collection seedling bucket 7 is equipped with valve 4, and an end of nettle 5 is connected on the head rope 2, and an end of the rope 6 that suspends is connected with flotation gear 3; The other end of suspension rope 6 and the other end of nettle 5 tie up on the static line 8 jointly, and an end of static line 8 is connected with fixture 9.
Embodiment two: the flotation gear 3 of this embodiment is a ball float; The effect of flotation gear in collecting work is that the connection of restricting through suspending makes fry collection net be in suspended state; Flotation gear 3 is a ball float; Also can be to float on other less objects of density waterborne, the annexation of other composition be identical with embodiment one.
Embodiment three: the fixture 9 of this embodiment is an anchor; Also other big objects of density that can sink under water; Fixture 9 has played and can remain in the fixing water layer during operation under water whole harvester; Thereby can obtain specifying the fry in the water layer, the annexation of other composition is identical with embodiment one.
Embodiment four: combine Fig. 2 that this embodiment is described, the head rope 2 of this embodiment is the steel ring of diameter 60-80cm.The diameter of the head rope 2 can cause harvester weight excessive greater than 80cm, is unfavorable for controlling the degree of depth of harvester residing water depth, especially shallow water body; The diameter of the head rope 2 can make the opening part of the head rope 2 too small less than 60cm, and inconvenient fry gets into fry and gathers net 1, thus the result that influence is gathered, and the annexation of other composition is identical with embodiment one, two or three.
Embodiment five: the order number that the fry of this embodiment is gathered net 1 is 28-35; This order is counted the made fry of scope and is gathered the collection that net relatively is fit to young postlarva; Both having avoided fry to gather the net from fry escapes; It is excessive to prevent that again fry collection net from receiving impact force of water flow, and the annexation of other composition is identical with embodiment one, two or three.
Operating process: when different offshore distances were gathered with different water layers simultaneously, the use river young postlarva harvester of many water layers carried out collecting work in can guaranteeing at one time.When carrying out collecting work, measure required length to the rope 6 usefulness survey tools that suspend at first on the water and be fixed to again on the nettle 5, whole harvester is put into water; Rope 6 length are fixing owing to suspend, thereby whole harvester can be suspended in the waters layer of observer's appointment, and the rope 6 that suspends will no longer be regulated under water; Be as the criterion with regular length waterborne; Fixture 9 is put into the bottom, whole harvester is fixed on specifies in the layer of waters, along with water impact fry collection net 1 opens; Fry gets into collection seedling bucket 7 with current, when collecting work finishes, opens valve 4 and can take out fry.
