As shown in fig. 1 and 2, a float ball 51 for indicating the position of the page is provided in the sample storage barrel 5, and a drain pipe 52 for draining the waste liquid is provided at the bottom of the sample storage barrel 5. Through setting up floater 51 in storing up appearance bucket 5, the user of being convenient for observes the extraction condition of water sample through floater 51, through setting up drain pipe 52 in the bottom of storing up appearance bucket 5, is convenient for discharge and the washing with the remaining water sample in storing up appearance bucket 5 after finishing detecting, avoids causing the pollution to the water sample of next extraction.
Embodiment two:
As shown in fig. 8 and 9, this embodiment is basically the same as the first embodiment except that: the outer peripheral surface of the rigid connecting rod 24 is sleeved with a floating plate 9 which can slide up and down, the floating plate 9 is made of a light material and can float on the surface of a water sample, the diameter of the outer edge of the floating plate 9 is slightly smaller than the inner diameter of the cylinder 21, the floating plate 9 is provided with a plurality of filter holes 91 which are penetrated up and down, the filter holes 91 are annularly arranged around the axial lead of the floating plate 9, and the lower end of the suction pipe 6 can be opposite to at least one filter hole 91 along the vertical direction. Thus, when the sampling tube 2 finishes sampling, the floating plate 9 floats on the surface of the water sample, and meanwhile, the floating plate 9 can keep a horizontal state under the constraint of the cylinder 21 and the rigid connecting rod 24, so that the floating plate 9 can generate a constraint effect on the water sample in the sampling tube 2, wave and wobble of the water sample in the rising process of the sampling tube 2 are reduced, the gravity center of the whole sampling tube 2 is kept stable in the rising process, the swinging phenomenon is relieved, and the convenience of sampling in a small-diameter wellhead is further improved; the lower end of the suction pipe 6 can be propped against the floating plate 9 and pressed into the water sample after the suction pipe is lifted in place, and the floating plate 9 cannot generate excessive resistance because the volume of the floating plate 9 is not large, and the filter holes 91 on the floating plate 9 can ensure that the suction pipe 6 cannot be blocked when the suction pipe 6 is propped against the floating plate 9 to suck the water sample, so that normal operation is ensured.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
