in addition, in the process that the liquid sampler sinks to the water area to be sampled, the liquid in different water areas can flow out from the first water inlet hole 121 and the second water inlet hole 231, so that in the ascending process of the liquid sampler, the float piece 2 and the sampling tank body 1 form a sealing space, and the sealing space can only be filled with the liquid in the water area to be sampled, namely, the liquid in the water area to be sampled plays a role in accurate sampling.

It should be noted that a fixing device may be disposed on the sampling tank 1, so that during the sinking and ascending processes of the liquid sampler, the sampling tank bottom 12 of the liquid sampler can move up and down towards the liquid level of the water area to be sampled through the fixing device; the fixing device may be a clamp fixed on the sampling tank 1, or a connecting rope tied outside the sampling tank 1, which is not limited in this application.

The working principle of the liquid sampler of the present invention is explained below:

as shown in fig. 1-7, a connecting rope with scales is tied on a sampling tank body 1, the sampling tank body 1 and a floater 2 are assembled before sampling, in the process that a liquid sampler sinks to a water area to be sampled, a sampling tank bottom 12 faces upwards the liquid level of the water area to be sampled, the liquid sampler slowly sinks to the depth of the water area to be sampled, and in the process of sinking, a movable plate 23 moves towards the liquid level of the water area to be sampled along a metal rod 13 due to the buoyancy effect of the liquid level of the water area to be sampled; at this time, the liquid sampler does not take the liquid sample in the water area to be sampled yet, and the liquid in the water area not to be sampled flows out through the first water inlet hole 121 and the second water inlet hole 231 and is not retained in the sampling tank body 1;

when the liquid sampler is regulated to sink to a specified position, the liquid sampler is slowly lifted to the liquid level of a water area to be sampled, the movable plate 23 is moved to the sampling tank bottom 12 by the pressure of the liquid, so that the movable plate is slowly attached to the sampling tank bottom 12, the groove 122 of the sampling tank bottom 12 is attached to the sealing bulge 232 arranged on the movable plate 23, and the effect of sealing and stopping water is achieved;

when the movable plate 23 reaches the sampling tank bottom 12, the sampling tank cover 21 of the float member 2 also completely covers the tank opening of the sampling tank body 1, so that the sealing effect is achieved, water is prevented from entering the sampling tank body 1 again, the sampling can be completed until the liquid sampler leaves the liquid, and at the moment, the liquid sample in the liquid sampler is the required liquid in the water area to be sampled.

The utility model comprises a sampling tank body 1 and a float part 2 movably connected with the sampling tank body 1; wherein, sample jar body 1 includes: a sampling tank wall 11; a sampling tank bottom 12 integrally formed with said sampling tank wall 11; a metal rod 13 with one end fixedly connected to the bottom 12 of the sampling tank; the float member 2 includes: a sampling tank cover 21; a connecting pipe 22 with one end fixedly connected with the sampling tank cover 21; a movable plate 23 fixedly connected to the other end of the connection pipe 22; connecting pipe 22 slip cover is established outside metal pole 13, solved and to have carried out the problem of taking a sample to appointed degree of depth water layer, simple structure, simple operation.
