Abstract
The utility model relates to a plankton collector. The plankton collector comprises a collection net and a box body connected with the collection net, wherein floating balls are arranged on the upper surface of the box body, a water pump is arranged in the box body, a water inlet is arranged on the upper portion of the box body, a filter screen is arranged on the water inlet, water is sucked into a water inlet pipe by the water pump after the water passes through the filter screen, enters into a water outlet on the lower portion of the box body through the water pump, and then enters into the collection net so as to filter plankton, and the floating balls suspend on a water surface. The plankton collector can suspend on the water surface, enables the plankton to enter into the water outlet after the plankton is sucked and filtered through the water pump in the box body, and collects the plankton through the collection net on the exterior of the water outlet. Compared with a common barrel type plankton collection net, the plankton collector has the advantages that passive collection is changed into active collection, collection efficiency is obviously improved, collection of the plankton is facilitated due to the fact that phototaxis lamps are arranged on the floating balls, and the plankton collection net can separate different sizes of the plankton, is convenient to use and low in cost, and can effectively save manpower and material resources.
Description
Technical field
The utility model relates to the biological harvester of a kind of Ecology, particularly relates to a kind of plankton collector.
Background technology
Plankton is to suspend to live in the aquatile in water, their abilities of not moving about completely, or the ability of moving about is very weak, can not make long distance moving, is not enough to resist the mobile of water.Plankton comprises phytoplankton and the large class of zooplankton two, and plankton individuality is very little conventionally, but quantity is more, distributes wide, aquatile circle, occupies critical positions.Plankton is not only the important bait of fish, and its structure of community and species composition are commonly used to evaluate the ecotope of water body.
Current, gathering shallow-layer waters plankton used tool is generally easy bucket formula plankton nets, its structure comprise collection ring and on collection ring fixing guard, plankton enters and gathers in net through collection ring circle mouth, so the size of collection ring mouth directly affects collecting efficiency.Meanwhile, collection ring circle mouth is also the outlet of the plankton escape of network access.The efficiency that this collection ring gathers is lower, needs special messenger to take time to gather, and while working in the wild, can waste time, and collecting efficiency is low, and impurity, rubbish etc. easily enter netting gear and causes drainage not smooth in addition, affect collecting efficiency.
Utility model content
The technical problems to be solved in the utility model: overcome defect of the prior art, the plankton that a kind of collecting efficiency is high, easy to use, automaticity is high collector is provided.
The technical solution of the utility model:
A kind of plankton collector, comprise collection net, also comprise the casing being connected with collection net, casing upper surface center is provided with ball float, between ball float and casing for being fixedly connected with or being flexibly connected, in casing, be provided with water pump, casing top is provided with water inlet, and water inlet is provided with filter screen, lower box is provided with delivery port, delivery port and collection net communicate, and described ball float is suspended on the water surface, on ball float top, is provided with light modulation.
Described collection net is inside and outside two-layer, gathers in net and is provided with bracing ring, and the outer aperture that gathers net is 60-66 μ m, and the aperture of internal layer collection net is 80-90 μ m.
Described water inlet is arranged on casing top, and around tank one week.
positive beneficial effect of the present utility model:
Collector of the present utility model can be suspended on the water surface, by the water pump in casing, will contain planktonic water and enter delivery port after by water pump suction filtration, by the collection net outside delivery port, plankton is collected, this device gathers net with common bucket formula and compares, from passive collection, become active collection, collecting efficiency can be obviously provided.
Collector ball float of the present utility model is provided with light modulation, is conducive to the planktonic collection of phototaxis; The biological collection of trip net is made as two-layer, the plankton varying in size can be collected respectively, and easy to use, cost is lower, can use manpower and material resources sparingly.
The outer import department of collector casing of the present utility model arranges filter screen, and effectively the part foreign material in filtered water, improve the collection efficiency that gathers net.
Collector of the present utility model adopts water pump to control water (flow) direction, can effectively prevent that the plankton in net from escaping, and greatly improves planktonic collecting efficiency.
Collector of the present utility model can all weather operations, and simple to operate, safety, is easy to apply.
Accompanying drawing explanation
Fig. 1 is one of structural representation of plankton collector.
Fig. 2 be plankton collector structural representation two.
In figure, 1 is ball float, and 2 is water inlet net, and 3 is casing, and 4 is water pump, and 5 for gathering net, and 6 is bracing ring, and 7 is the light modulation that becomes.
Embodiment
embodiment 1: ginsengsee Fig. 1, a kind of plankton collector, comprises collection net, also comprise and the casing that gathers net and be connected, the center of casing upper surface is provided with ball float, between ball float and casing for being fixedly connected with, in casing, be provided with water pump, casing top is provided with water inlet, and water inlet is provided with filter screen, and water is by sucking water inlet pipe by water pump after filter screen, through water pump, enter the delivery port of lower box, then water enters and gathers net filtration and go out plankton, and the ball float of harvester is suspended on the water surface, and collection net is individual layer; Described water inlet is arranged on casing top, and around tank one week, has so not only been conducive to filter but also do not affect the flow velocity of water.
embodiment 2:basic identical with example 1, difference is:
ginsengsee Fig. 2, between ball float and casing, for being flexibly connected, be provided with light modulation on the top of ball float, it is inside and outside two-layer gathering net, gathers in net and is provided with bracing ring, and the outer aperture that gathers net is 60-66 μ m, and the aperture of internal layer collection net is 80-90 μ m.
It is larger that internal layer gathers screen distance, for gathering larger plankton; Outer collection screen distance is less, for gathering less plankton, has realized when gathering plankton is carried out to initial gross separation.
Claims (3)
1. a plankton collector, comprise collection net, it is characterized in that: also comprise the casing being connected with collection net, casing upper surface center is provided with ball float, between ball float and casing for being fixedly connected with or being flexibly connected, in casing, be provided with water pump, casing top is provided with water inlet, and water inlet is provided with filter screen, lower box is provided with delivery port, delivery port and collection net communicate, and described ball float is suspended on the water surface, on ball float top, is provided with light modulation.
2. plankton collector according to claim 1, is characterized in that: described collection net is inside and outside two-layer, gathers in net and is provided with bracing ring, and the outer aperture that gathers net is 60-66 μ m, and the aperture of internal layer collection net is 80-90 μ m.
