In addition, when zoobenthos being collected to sampling, therefore because zoobenthos is freely distributed in water body unlike plankton, but conventionally live in the more environment of the foreign material such as shale or cobble substrate, sometimes only with above-mentioned, adopt suction nozzle 101a and can not aspirate efficiently sampling.For being applicable to such sampling environment, the inventor proposes the suction nozzle of adopting of variation as follows.
As shown in Fig. 2 (b), this variation adopt suction nozzle 101b on above-mentioned basis of adopting suction nozzle 101a, in a side of suction inlet, along suction inlet direction, be placed with the harrow nail of some teeth.Collecting when sampling, utilize this harrow nail that cobble or impurity are pushed aside, and disturbance is hidden in zoobenthos wherein, by suction inlet, this zoobenthos is sucked and adopts suction nozzle 101a simultaneously.Thus, water-bed bulk object (such as stone, fallen leaves, rubbish etc.) rake can be opened, and the zoobenthos of energy disturbance respective regions, is convenient to suction collection.Preferably harrow nail is arranged in to the scanning direction advance side of suction inlet.In addition, also can all be arranged with this harrow nail in the both sides of suction inlet, so that adopt the shuttle-scanning suction of suction nozzle.
In addition, Fig. 2 (c) proposed the another kind of suction nozzle of adopting with harrow nail.This adopts suction nozzle 101c whole is mace shape, and caput is general cylindrical shape, the sealing of columnar one end, and the other end is communicated in conduit 103, along columnar side circumference, is scattered with some outstanding harrow nails laterally, and the space between each harrow nail is scattered with suction inlet.Utilize the suction nozzle of adopting of this shape, water-bed bulk object (such as stone, fallen leaves, rubbish etc.) rake can be opened equally, the zoobenthos of the respective regions of energy disturbance simultaneously, is convenient to suction collection.
In addition, Fig. 2 (d) proposed the another kind of suction nozzle of adopting with harrow nail.This adopts suction nozzle 101d whole is seedpod of the lotus head, is scattered with some outstanding harrow nails laterally in the general plane part of shower nozzle, and the space between each harrow nail is scattered with suction inlet.Utilize the suction nozzle of adopting of this shape, water-bed bulk object (such as stone, fallen leaves, rubbish etc.) rake can be opened equally, meanwhile, the zoobenthos of energy disturbance respective regions, is convenient to suction collection.
In addition, the gross area of the suction inlet shown in preferably above Fig. 2 (a)～(d), with sucker rod (or conduit) with to adopt the sectional area of suction nozzle connection suitable, the swabbing pressure when guaranteeing to adopt suction.
(quantitatively frame)
In addition,, when needs carry out the quantitative collection of zoobenthos for example, quantitative frame can be set and coordinate the work of inhaling device 100 of adopting.Fig. 3 is the figure of the structure of explanation quantitative frame of the present invention and variation thereof.(a) of Fig. 3 illustrates a kind of quantitative frame 104, it comprise rectangle (containing square) framework 1041, be connected in framework 1041 recovery rope 1042, be connected in the mooring anchor 1043 of framework 1041.
The a pair of length of side of design framework 1041, makes it suitable with above-mentioned suction inlet length of adopting suction nozzle (101a or 101b) on one side, and design its another to the length of side, make to meet required quantitative area.
The one end of reclaiming rope 1042 is connected in quantitative frame 1041, and the other end is grasped by user, for reclaiming quantitative frame.
Due to when the quantitative collection zoobenthos, quantitatively frame 104 is actual is placed in water-bedly, and when current are stronger, quantitatively frame is easily moved, and causes intending the area inaccurate of quantitative collection especially.Therefore mooring anchor 1043 is set, is not moved after making quantitative frame 104 fall into the bottom.At this, it should be noted that, so long as can temporarily fix the member of the position of quantitative frame 104, be not limited to above-mentioned mooring anchor 1043, pouring weight 1044 that for example also can be as shown in Fig. 3 (b), or at least diagonal position (being four bights in this example) at framework 1041 as shown in Fig. 3 (c) arranges staple 1045, make when quantitative frame 104 is placed in to the bottom, staple 1045 can stretch into water-bed mud or crack of stone, thereby accurately fixes quantitative frame 104.Now, also can staple 1045 be set respectively at the upper and lower surface of framework 1041, no matter which faces down while making framework 1041 fall into the bottom, staple 1045 that can be by respective face is fixed position effectively.In addition, can also as shown in Fig. 3 (d), by cotton rope, connect buoy 1046 respectively by least diagonal position (being four bights in this example) at framework 1041; buoy 1046 can not only make quantitative frame 104 according to required posture, fall into the bottom reposefully; can also play a role as the station location marker of quantitative frame 104; special in the sampling environment of water turbidity, this effect is very outstanding.Certainly, the gross buoyancy of buoy 1046 is less than the weight of quantitative frame 104 own, so that quantitatively frame 104 can sink under water.
Certainly, above-described quantitative frame is not only applicable to aquatile harvester of the present invention, can also effectively be applicable to zoobenthos harvester, such as rope uncle net, D type net, right angle net etc. of prior art.
In addition, Fig. 4 be explanation another kind of variation quantitative frame 104 structure and with the figure coordinating that adopts suction nozzle 101.As shown in Figure 4, quantitatively frame 104 is right angle " U " shape, should on the dual-side of " U " shape frame, have chute 105, and base length matches with the length of adopting suction nozzle 101.In addition, as shown in Figure 4, the two ends of adopting suction nozzle 101 have respectively an outstanding limit component 106 laterally, in the present embodiment, this limit component 106 is for having the nail-like of minor diameter part and large-diameter portion, and one end of minor diameter part is connected in the side of adopting suction nozzle 101, and the other end is connected in large-diameter portion.The path length of minor diameter part is slightly less than the width of the chute 105 of quantitative frame 104, makes to stretch into chute and moves along chute; The path length of large-diameter portion is greater than the width of chute 105, and while making in minor diameter part stretches into chute, large-diameter portion is stuck in the outside of quantitative frame 104, and the movement of suction nozzle 101 in the direction of quantitative frame base adopted in restriction.Thus, in the time will using quantitative frame 104, the minor diameter part of adopting the limit component 106 at suction nozzle 101 two ends is slipped into from one end of corresponding chute respectively, under the restriction of large-diameter portion, adopt suction nozzle 101 and can only move along chute 105.In the situation that it is certain to adopt the length of suction nozzle 101, by designing the length of the chute on the side of quantitative frame, just can gather needed quantitative area.
In addition, the technical characterictic of the mooring anchor of using about above-described quantitative frame, weight block, staple, buoy, quantitatively frame also can have wherein multiple simultaneously, now by the technique effect that has each feature concurrently and bring.
(classified filtering device)
Get back to Fig. 1, the unitary construction of classified filtering device 200 has been shown in Fig. 1.In the example of Fig. 1, classified filtering device comprises three layers of screen 201,202,203 being inclined relative to horizontal on the screen frame 301 that is arranged on main body 300.The sieve aperture (mesh) of three metafiltration sieves 201,201,203 successively reduces, thereby can sort out the object to be checked (such as plankton, zoobenthos, sand grain etc.) of different-grain diameter.The concrete size of the sieve aperture of each metafiltration sieve need to design according to actual sampling.
In addition, screens at different levels are set to certain angle of inclination with respect to the horizontal plane, make the object to be checked that is fed into screen under Action of Gravity Field, to flow downward and to filter on one side on one side, thereby compare when being horizontally disposed with screen, more be conducive to object to be checked being uniformly distributed on screen, guarantee the effect of fully filtering, also help the collection of sample collection device, , because screen tilts, therefore as long as sample collection device 400 is set in screen lower end, the filtrate being filtered out will automatically be collected in sample collection device 400 under the washing away of current, without specially cleaning again, collect operation.
Shown in Fig. 1 be three metafiltration sieves parallel oblique the state installed, screen progression is not limited to three layers, for example, can be also one deck, preferably more than two-layer, more preferably more than three layers, can increase as required or reduce.Multilayer screen also may not need parallel oblique, can, according to the state of current (such as flow velocity, flow etc.) or the adequacy requirement of filtering etc., set respectively the angle of inclination of each layer.In addition, each metafiltration sieve can not be also to tilt towards a direction, but intersects to tilt with "the" shape state.
In addition,, when the water turbidity being aspirated is up larger, for improving the efficiency of filtering, the effect that adds strong filter, can make each metafiltration sieve rock.The mechanical realization rocking about realizing this, that for example can utilize crank connecting rod apparatus is converted into rotation reciprocating theory of mechanics, for example, as shown in Fig. 5 (a), a side at screen frame 301 is installed crank axle device 302, and respectively by connecting rod connecting crank shaft device 302 and screen at different levels, specifically, one end of connecting rod is connected in the crank-pin of crank axle device 302 in the mode that can freely rotate along the circumferencial direction of crank axle, the other end is connected in screen in mode free to rotate.In addition, the head and the tail two ends of screens at different levels are erected at respectively on the set slide rail of screen frame 301, and screens at different levels can, under the drive of crank connecting rod apparatus, laterally be slided along slide rail.Manner as screens at different levels, herein exemplified with slide rail, but also can adopt other mechanical realization, for example hang on last layer screen or screen frame 301 in mode that can Free Slosh by messenger wire at four angles of each metafiltration sieve, thus, when the main shaft of crank axle device 302 is rotated, crank-pin drivening rod moves back and forth, and then drives each metafiltration sieve to rock regularly.In addition, also screen 201 that can the Jin Shi the superiors is connected in crank axle device 302, other each metafiltration screening is relatively unfixing by the screen 201 of the mode Yu Gai the superiors of for example welding, thus, when the superiors' screen 201 rocks with crank axle device 302, below each metafiltration sieve also synchronize and rock with it.
These are only an example, the mechanical schemes of rocking is also not limited to crank axle linkage, such as realizing this effect by any-modes such as cam gear, connecting rod of eccentric wheel devices.In addition, be also not limited to make each metafiltration sieve synchronously to rock, as long as guarantee that the screen of lower floor can receive the object to be checked after upper strata screen filters completely, also can only make the screen of certain layer rock as required.
More than show the example that screen frame is motionless, each metafiltration sieve is rocked relatively.In addition, can also as shown in Fig. 5 (b), make each metafiltration sieve relative with screen frame fixing, by being installed on the crank axle device 302 of main body, drive whole screen frame and screen to rock with respect to main body.
In addition,, when adopting the aspirator of vacuum draw mode described later, can drive whole suction filtration case to rock with respect to main body by being installed on the crank axle device 302 of main body.
