Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be given with reference to the accompanying drawings and preferred embodiments.

As shown in the attached drawings 1-5, the utility model discloses a portable automatic water sampler, which comprises a box body 1, two or more rows of sampling bottles 5 arranged in the box body 1 and a sample introduction head 7 correspondingly arranged above each row of sampling bottles 5, wherein the sample introduction head 7 can perform linear motion along the arrangement direction (namely, the direction of each row) of the sampling bottles under the action of a driving device. In this embodiment, two rows of sampling bottles are provided, each row has 6 sampling bottles, and along the transverse arrangement shown in fig. 2 (i.e. the length direction of the box body 1), two corresponding sampling heads 7 are also provided, and the driving device drives the sampling heads 7 to also move transversely.

Utilize the unit of adopting water to pump water to advance kind head 7 position department from the waters of awaiting measuring to add in the sampling bottle that corresponds, adopt the water unit including sampling pump 2, with the pipeline of the delivery port intercommunication of sampling pump 2 and set up the appearance head 7 that advances at the pipeline other end. Preferably, a sample injection pump 3 is further arranged on the pipeline, that is, the sampling pump 2, the sample injection pump 3 and the sample injection head 7 are communicated in sequence. The number of the sample injection heads 7 corresponds to that of the sample injection pumps 3, and the sample injection pumps 3 are connected in series in front of each sample injection head 7. Similarly, for the present embodiment, there are two sample injection pumps 3, which are respectively communicated with the two sample injection heads 7, so as to implement the independent control liquid injection for the two sample injection heads 7. When two sampling pumps 3 work simultaneously, can realize parallel sampling, adopt the water of a position into two sampling bottles simultaneously, realize parallel sampling. And if only one sample feeding pump 3 works, the sampling is carried out by conventional single bottle separation. The excess water sample can be discharged from the water outlet.
