For stomata, upper side through hole is used to set water nozzle 122, and certainly, the effect of upper lower through-hole can also be exchanged, and the present invention is not limited this
System.
Jack 130 is fixed on hull, suitable for by folding and unfolding draught line 140 come lifting or sinking sampling tank 110, its
Sampling tank can be sunk into arbitrary target water level as needed, to realize the stratified sampling of each water level.According to one embodiment,
Jack 130 can be automatic winch.
In addition, layered sampling device 100 can also include pulley 160 and support 170.Wherein, pulley 160 is located at positioning seat
Above 120 intermediate throughholes, suitable for by draught line 140 around being mapped in intermediate throughholes.Support 170 can be lifted under suspension bracket 150,
Suitable for stationary positioned seat 120 and pulley 160.Support 170 includes two A font plates, and the two A font plates are separately fixed at positioning
The both sides of seat 120, it can be fixedly connected by one or more crossbeams between two plates, wherein a crossbeam can pass through pulley
160 center is to fix the pulley.Of course it is to be understood that the plate for other shapes, such as H can also be arranged as required to
Template, drum plate etc., as long as fixed undertaking effect, the invention is not limited in this regard can be realized.
According to one embodiment, support 170 can be lifted under suspension bracket 150 by universal structure.Such as institute in Fig. 5 A and 5B
Show, two crossbeams are provided with support 170, and downside crossbeam is used for fixed block 160, and upside crossbeam is arranged in the horizontal stroke of suspension bracket 150
In groove, a universal structure (i.e. two cross one another axles) is formed between suspension bracket 150.The connected mode of this universal structure
Hull rolling pitching can effectively be reduced to positioning seat and the influence for hanging operation, make positioning seat 120 and messenger wire is kept and the water surface
Vertical relation, positioning and guiding and hang operation so as to be better achieved.
Usually, in the sinking watching of sampling tank 110, the check valve of upper lower valve body is opened, and water body flows from lower valve body 113
Enter and flowed out again through upper valve body 112.Stop sinking when sampling tank 110 reaches the sampling depth of water, the water body of current depth is flowed into bucket
In vivo, the closed check valve of upper lower valve body.Recovery operation process, by winch acting in opposition lifted sampling tank 130, now by
Influence of hydraulic pressure check valve is closed all the time, to ensure that sampling water body will not be spilt out outside.And receive and carried when sampling tank 110
When being raised to 150 top of suspension bracket, by the guiding function of multi-joint structure in the guide plate 123 and sampling tank 111 of positioning seat 120,
The locating rod termination of the part of upper valve body 112 can be quickly with positioning seat 120 locating slot 121 coordinate, the suction of the part of upper valve body 112
Water pipe 115 can also engage with the water nozzle 122 of positioning seat quickly.Moreover, the universal structure between support 150 and suspension bracket 170 connects
Connect, further ensure that fast positioning process.The automatic method for rapidly positioning of the above substantially can be accelerated on the whole
Sample rate, further save manpower and materials.
Afterwards, it is possible to the water of sampling tank 110 is withdrawn into sampling via suction hose 114, water nozzle 122 and flexible pipe with pump
Storehouse carries out classification deposit, is not in any sample leakage in whole process.And in sampling process, a water suction of sampling tank
The connection flexible pipe of pipe 120, another suction hose connect the stomata on positioning seat 120, and gas endlessly can enter in water body,
To ensure that air pressure is consistent with the external world in staving, so as to effectively improve sampling rate.And if on the bucket wall of sampling tank 110
A pump mouth is specially set if being used to draw water, then to be required for opening the pump mouth when drawing water every time, after the completion of drawing water again
The pump mouth is closed, is likely to reduce the seal of the pump mouth over time, the leakage of lifting process further occurs
Water phenomenon.Moreover, this pumping method is also easy to because air pressure not enough causes sampling slowly or even can not sampled in bucket.And
This stratified sampling method of the present invention, fast positioning and quick sampling can be realized, and it is simple in construction easily operated.
