Portion 1062 opens or closes water inlet.
Specific workflow is as follows：
Before water acquisition is started, sample bottle pipe 101 is first placed in the vertical water acquisition of composition build in closing device stent 104
Device, while remote-controlled launcher sends to remote-receiver and instructs, electromagnet must make energization, the water inlet and bottle of sample bottle pipe
Mouth closing assembly is in 90 degree of right positions between lower part, and the water inlet of sample bottle pipe is in open position.Then separation type is stood
Formula hydrophore is put into the river of lake, is reached and is specified water acquisition position, adopts to obtain columnar water.After water acquisition, remote-controlled launcher to
Remote-receiver sends instruction, electromagnet dead electricity, and bottleneck closing assembly lower part is closed to bottleneck closing assembly top, seals sample
The water inlet of product bottle pipe.The vertical hydrophore of separation type is finally pulled out into lake river, is covered in the both ends open of sample bottle pipe
After bottle cap, the water acquisition flow of sample bottle pipe progress next time is replaced.
Variation as the present embodiment：
As shown in Figure 1, liquid level sensor (depth transducer, GPS etc.) is also equipped with above-mentioned stent, for determining to set
Standby underwater depth and position coordinates；
Elevating mechanism is additionally provided with above-mentioned stent, for sinking under water or pulling out the water surface by equipment；The elevating mechanism can
Think automatically controlled lifting motor, the scaling of rope which is connected by driving with stent etc., realizes and stent is lifted and put
Under.
Scheme one, during use, which is sent to equipment current depth or position coordinates in real time
Control device；
After depth or position coordinates reach setting range, control device carries out following process：
S1：Sent to elevating mechanism and stop declining instruction；Elevating mechanism stops putting rope after receiving the signal, makes equipment not
Decline again；
S2：Send the instruction for closing electromagnet；Electromagnet is closed, and the intake of sample bottle pipe is closed；
S3：The instruction risen is sent to elevating mechanism；Elevating mechanism starts upward tow.
After sample bottle pipe leaves the water surface, electromagnet can be manually opened, and in sample bottle pipe two end cap upper bottle cover
To realize finishing for the phase flow.
Sample bottle pipe sample bottle pipe
The effect of the present embodiment and effect：
1. it is in the present embodiment, dismantled and assembled composite module by sample bottle pipe and closing device support Design, according to difference
Water acquisition require it is replaceable needed for sample bottle pipe.
