Space, upper position is gas chamber, lower orientation be liquid chamber；Gas chamber has air-flow interface, and liquid chamber has feed liquor interface and out liquid interface,
Liquid interface connects collection bottle out；One end connection air-flow interface, the other end of short plastic flexible pipe are connected to host；Long plastic flexible pipe
One end connection feed liquor interface, the other end protrude into river and lake.
The above-mentioned small-sized water sample acquisition filter device suitable for river and lake, battery is housed in host, is set on host
It is equipped with the charging interface for charging.
The aforementioned small-sized water sample acquisition filter device suitable for river and lake, be additionally provided on host control to adjust key and
Display screen.
The aforementioned small-sized water sample acquisition filter device suitable for river and lake, graduation mark is equipped on the side wall of collection bottle.
The utility model has the beneficial effects that compared with prior art, the utility model utilizes the micro computer control in host
The movement for the intermittent pressing filter that circuit board, solenoid valve and the pressure of air pump automatic mold apery hand one one are put, realizes automatic water collecting
Filtering, liberated manpower, saved manpower, greatly improved work efficiency, and its structure is simple, small in size, convenient disassembly,
Easy cleaning, portable, cost much less than the water sampler of profession, it is practical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the solenoid valve and air pump control principle drawing of the utility model.
The utility model is further described with reference to the accompanying drawings and detailed description.
Specific embodiment
Embodiment 1: as shown in Figure 1, by host 1, three-way connection device 2, long plastic flexible pipe 3, short plastic flexible pipe 4, filtering
Net 5 and collection bottle 6 are constituted, and filter screen 5 is mounted on the top of long plastic flexible pipe 3, for being filtered to the water sample of acquisition；Collecting
The side wall of water bottle 6 is equipped with graduation mark 10, convenient to measure to the water sample of acquisition.Control circuit board, electricity are provided in host 1
Magnet valve and air pump can press one to put intermittent pressing filter movement with automatic mold apery hand one.Control circuit board uses single-chip microcontroller, gas
Pump uses commercially available micro air pump, and solenoid valve uses commercially available two-position four-way solenoid valve, and its principle is as shown in Figure 2.It is controlled when passing through
When circuit board controls solenoid valve D switching electricity, by the mechanical movement of electromagnet in solenoid valve D, to control the pumping of air pump F
And outgassing, to complete to collect and filter the process of water sample.The size of electric current determines the extraction rate of air pump, to reach control
The purpose of dynamics.It is provided on host 1 and controls to adjust key 8 and display screen 9, key 8 is adjustable to be squeezed by controlling to adjust
Surging, since different monitoring points water quality situation is different, excessively muddy water sample is squeezed difficult, and the extruding dynamics needed is larger,
Opposite clear water sample extruding is easier to, and the smaller of the dynamics needed can show the working time by display screen 9, facilitate sampling people
Member's record.One disc diaphragm 11 is housed in 2 inner cavity of three-way connection device, is opened among disc diaphragm 11 with open in usual
The inner cavity of three-way connection device 2 is divided into two opposite skies in orientation in diagonally distributing by the cusp 12 of mouth, disc diaphragm 11
Between, upper position is gas chamber 13, and lower orientation is liquid chamber 14；Gas chamber 13 has air-flow interface 15, and liquid chamber 14 has 16 He of feed liquor interface
Liquid interface 17 out, liquid interface 17 connects collection bottle 6 out；One end of short plastic flexible pipe 4 connects air-flow interface 15, short plastic flexible pipe 4
The other end be connected to host 1；One end of long plastic flexible pipe 3 connects feed liquor interface 16, and the other end of long plastic flexible pipe 3 protrudes into river
In lake, for acquiring water sample from river and lake.According to on-site actual situations and needs, the length of long plastic flexible pipe 3 is 3-5 meters, is needed
It is inserted directly into the water surface, the length of short plastic flexible pipe 4 is usually at 0.3 meter or so.For convenience of field work, equipped with storage in host 1
Battery is provided with charging interface 7 on host 1, and 4-5 hour of sustainable work, facilitates outdoor study after charging.
Working principle: when air pump pumping, the opening of cusp 12 is bonded closing, then forms negative pressure in gas chamber 13, when
When negative pressure reaches a certain size, disc diaphragm 11 is overturn, and position outstanding reversely protrudes, and 13 space of gas chamber is made to become smaller and liquid
14 space of room becomes larger, and then generates negative pressure in liquid chamber 14, the suction function in insertion river and lake in long plastic flexible pipe 3 on, this
When the water body that is inhaled into flow from below to up, 14 lower section of liquid chamber is temporarily stored into after filter screen 5 goes out 16 surrounding space of liquid interface；
When air pump outgassing, gas chamber 13 restores rapidly normal pressure, and disc diaphragm 11 restores its shape and cusp 12 opens opening, makes liquid chamber
14 space becomes smaller, air pressure becomes normal pressure, and the water body for being then temporarily stored into 14 lower section of liquid chamber will be rapidly flowing into collection bottle 6, real
Existing water sample automatic collection.
The embodiments of the present invention is not limited to the above embodiments, and is done without departing from the purpose of the present invention
Various change out belongs within the protection scope of the utility model.
