Abstract
The utility model discloses a retractable floating-plant sampler, belongs to the field of biological breeding and cultivation and relates to a tool for large submerged plant sampling. The retractable floating-plant sampler is characterized in that the retractable floating plant sampler consists of an upper square frame and a lower square frame which are matched, i.e. an intercepting device and a framing device; the matching means that the upper square frame enters the lower square frame in a shearing state; the lower frame is the framing device and is provided with a vertical edge, a cutting edge is arranged on the inner side of the edge and is matched with a cutting edge on the outer side of the edge of the intercepting device, i.e. the upper square frame; the depth of each frame side is approximately equal to the width of a palm, the upper frame side is slightly shallower than the lower frame side, and an outward extension stop which is in parallel with the frame sides is arranged at the top of the upper frame; hooks are arranged at the bottom of the lower frame according to the needs, and a net bag is used as a collecting device. The retractable floating-plant sampler has the beneficial effects that floating plant which is used as a sample can be conveniently framed; the upper frame is pressed downwards, the inner cutting edge and the outer cutting edge on the edges of the upper frame and the lower frame are intersected, the floating plant outside the frames is cut off, the floating plant in the frames slide into the net bag, i.e. the collection device, and the floating plant with area of one square meter can be obtained; the sampler is convenient to operate, the sampling accuracy is high, the structure is simple, and the sampler is portable and is a practical floating-plant sampler.
Description
Technical field
Belong to biological self reproducing cultivation field, relate to the sampling thief instrument of a kind of pleuston, exactly relate to the instrument of aquatic floating plant Ecological Investigation, sampling.
Background technology
While gathering compared with pleuston in deep water body, ship is difficult for fixing in water, rises and falls indefinite with ripple, determines that sample prescription is more difficult and inaccurate.Traditional framework acquisition method by four long be that the batten of 2 meters is made, head and the tail connect, tie point is fixed, batten expansible closes up, and closes up into " one " word shape while carrying.Can substantially solve Sampling.But when investigation pleuston distribution, the sample prescription of collection, because ship is in water level fluctuation, makes pleuston rock, push at the water surface, so that assemble, the pleuston of final impact sampling distributes and density; In addition, for the relatively large pleuston of volume, as water caltrop, the chrysanthemum fire hose etc., existing a part for a strain plant outside sample prescription, if adopt existing sampling thief to collect, can only be collect or give up whole plant, cause investigation result to be a greater impact, very inaccurate.
Summary of the invention
The utility model provides a kind of sampling convenient, gathers accurately, simple in structure, carrying portable, easy to operate telescopic pleuston sampling thief.
The technical scheme that the utility model is taked:
Telescopic pleuston sampling thief, confines device, capture device, gathering-device and control handle by pleuston and is formed, and its scheme is: by upper and lower two square frames that match, be respectively and confine device and capture device; Described matching is that upper square frame enters lower square frame with shearing condition; Lower square frame, for confining device, is a lower square frame with perpendicular edge edge, and bead inner side band sword matches with the sword in square frame bead outside on capture device; The dark about palm of edge is wide, and upper edge is slightly shallower than lower frame, and there is the overhanging stopper of parallel edge on upper ledge top; Suspension hook is set at the bottom of lower frame as required, and the string bag is gathering-device, hangs on suspension hook; Two terminations of the X shape handle being connect by axle, are respectively vertically fixed on upper and lower edge mid point, and handle has sleeve can supply to extend.
The beneficial effects of the utility model are:
Can conveniently confine the pleuston as sample; Upper ledge presses down, and the inside and outside sword of upper and lower frame bead intersects, and cuts off the outer pleuston of frame, leaves pleuston in frame and slips into string bag gathering-device, obtains the pleuston of 1 square meter; Easy to operate, gather accurately, simple in structure, carrying portable, is a practical pleuston sampling thief.
Accompanying drawing explanation
The pleuston gathering-device schematic diagram of Fig. 1, closure state,
The pleuston gathering-device schematic diagram of Fig. 2, open configuration.
Embodiment
Now the utility model is described in further detail by reference to the accompanying drawings,
Telescopic pleuston sampling thief, confines device, capture device, gathering-device and control handle by pleuston and is formed, and its structure is: by upper and lower two square frames that match, be respectively and confine device 1 and capture device 2; Described matching is that upper square frame enters lower square frame with shearing condition; Lower square frame, for confining device, is a lower square frame with perpendicular edge edge, and bead inner side band sword matches with the sword in square frame bead outside on capture device; The dark about palm of edge is wide, and upper edge is slightly shallower than lower frame, and there is the overhanging stopper 3 of parallel edge on upper ledge top; Suspension hook is set at the bottom of lower frame as required, and the string bag is gathering-device 4, hangs on suspension hook; Two terminations of the X shape handle 5 being connect by axle, are respectively vertically fixed on upper and lower edge mid point, and handle has sleeve can supply to extend.
Described upper square frame enters lower square frame with shearing condition, and its structure is: upper and lower two edges (6,7) relative with handle are circular-arc take handle rotating shaft as the heart.
The described suspension hook that arranges is as required that set suspension hook can not make to intercept pleuston and skids off from hang seam.
The described string bag, its width of mesh skids off from mesh for not making to collect pleuston.
Described X shape handle has sleeve can supply to extend.
Described axle connects, and is that two handles are worn axle connection by punching.
Described square frame, its edge is respectively got 1 meter long.
