This accuracy of detection.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with
The utility model is described in further detail for the drawings and specific embodiments.
Refer to Fig. 1, Fig. 1 is that plankton collecting device provided by the utility model is a kind of
The structural representation of detailed description of the invention.
In a kind of detailed description of the invention, plankton collecting device provided by the utility model
Including enrichment bottle 1, it is fastened on the bottle cap 2 of described enrichment bottle 1 opening, and is arranged at described richness
The collection ware 3 of collection bottle 1 liquid outlet, collects and there is not annexation between ware 3 and enrichment bottle 1,
Collection ware 3 is simply set in the liquid outlet of enrichment bottle 1, and collecting ware 3 can be relative to richness
Collection bottle 1 rotates；Described enrichment bottle 1 includes cylindrical section 11 and connects with described cylindrical section 11
Conical section 12, described conical section 12 is tapered in the direction upper shed away from described cylindrical section 11,
And the bottom contraction of its described conical section 12 forms liquid outlet；It is provided with on described liquid outlet and opens
Or the liquid valve door 4 closed, the sidewall of described cylindrical section 11 offers discharge outlet, described
The water discharging valve 5 opened or close it is provided with in discharge outlet.
Above-mentioned water discharging valve 5 can be the structure such as rubber stopper or plastic plug, opens row at needs
During penstock 5, pull out rubber stopper or plastic plug, when needing to close water discharging valve 5, clog rubber
Plug or plastic plug, to simplify apparatus structure, reduce cost.In theory, this draining
Valve 5 can be other forms such as slide valve, when needs are opened, promotes slide valve to open i.e.
Can.
In order to improve sampling precision, it is simple to read volume of water sample, the axial direction of cylindrical section 11 sets
Being equipped with scale 7, the precision of this scale 7 and scope can determine according to requirements, do not do at this
Repeat.
In the course of the work, sample collecting is placed in enrichment bottle 1, and water sample stands, and waits to swim
Biodeposition, to behind the bottom of enrichment bottle 1, opens out water discharging valve 5 to release unnecessary water sample,
And making supernatant maintain specific water level, in order to subsequent quantitation water outlet prepares；Then will collect
Ware 3 is set in the bottom of enrichment bottle 1, opens liquid valve door 4, and the collected concentrating sample of order is pressed
Preset vol enters collection ware 3.So, make to concentrate by the design of funnel shaped conical section 12
After bottom sample can be collected completely, and available water discharging valve 5 discharges unnecessary water sample, and
The bottle external and internal pressure of balance is provided in flowing water Valve sampling process；Therefore, this plankton is adopted
Acquisition means is easy to carry, simple to operate, and it can be avoided that bottom water body is disturbed by concentration process
Dynamic, thus ensure that the sample after concentration is closer to the truth, and then reduce reality
Test deviation, improve pattern detection precision.
Specifically, as shown in Figures 2 and 3, above-mentioned liquid valve door 4 includes canned paragraph 41 He
Active segment 42, described canned paragraph 41 is fixed on described liquid outlet, and is additionally provided with on it and axially passes through
Wearing the first through hole of described canned paragraph 41, described active segment 42 axial rotation is installed on described solid
The section of determining 41, and on it, offer the second through hole axially penetrating through described active segment 42；Described go out
When fluid valve 4 is in open mode, described first through hole is connected with described second through hole, institute
Stating liquid valve door 4 when being closed, described first through hole ends mutually with described second through hole.
When liquid valve door 4 is closed, the first through hole and the second through hole are staggered, and both do not connect
Logical, and when needs liquid valve door 4 is opened, drive active segment 42 relative to canned paragraph 41 turns
Move the position being connected to the first through hole and the second through hole, the controlling party of this liquid valve door 4
Just, and structure is relatively simple, thus simplifies apparatus structure, reduces the design of device and makes
Use cost.
From theory, liquid valve door 4 is not limited to above-mentioned form, as long as being capable of out
Opening or closing of liquid mouth, such as, liquid valve door 4 can also be electromagnetic valve, works as needs
When opening, sensor detects opening signal and automatically turns on electromagnetic valve, when needs are closed,
Sensor detects that shutdown signal Self-shut electromagnetic valve, opening signal and shutdown signal can be led to
Cross the modes such as button input to send.
Further, as shown in Figure 4 and Figure 5, this plankton collecting device also includes hollow
Control bar 6, one end of described control bar 6 is connected in described active segment 42, and its liquid enters
Mouth is connected with described second through hole, and the liquid outlet of described control bar 6 is positioned at described collection ware
3 is interior and affixed with collecting ware 3；When collection ware 3 being overlapped enrichment bottle 1, rotating collection
Ware 3 drives control bar 6 to rotate, and active segment 42 can be driven to rotate relative to canned paragraph 41,
Thus drive liquid valve door 4 to open, to improve operation ease and the reliability of liquid valve door 4,
And the control of liquid valve door 4 is realized by this kind of form, it is to avoid and water sample disturbance, improve and take
Sample precision.It is apparent that when being not provided with this control bar 6, collection ware 3 and enrichment bottle 1 can be made
When there is suitable distance, manually Unscrew liquid valve door 4.
For the ease of being fixed, prevent from rotation process occurs transfer, at described active segment 42
Offering square opening on the end face of described control bar 6, described control bar 6 is connected in described
One end of active segment 42 is square structure, and described square structure is connected in described square opening, this
Sample, provides anti-circumferential rotation structure by square fit form, improves operating reliability.
It should be appreciated that control bar 6 and active segment 42 fit, controlling bar 6 can overlap
Within being located at active segment 42, within active segment 42 also can be sheathed on control bar 6；On it addition,
State and circular port or the trapezoidal hole etc. with anti-rotation plane on the end face of active segment 42, can be offered
Form substitutes square opening, it is thus evident that the shape controlling bar 6 should be with the shape phase contract of this blocked hole
Close.
It is pointed out that ordinal numbers such as " first, second " described in literary composition is identical in order to distinguish
The different structure of title, convenient only for describing, do not indicate that certain order, more should not be construed as
Any restriction.
Above plankton collecting device provided by the utility model is described in detail.
Principle of the present utility model and embodiment are set forth by specific case used herein,
The explanation of above example is only intended to help to understand that method of the present utility model and core thereof are thought
Think.It should be pointed out that, for those skilled in the art, without departing from this reality
On the premise of new principle, it is also possible to this utility model is carried out some improvement and modification, this
A little improvement and modification also fall in this utility model scope of the claims.
