Through adopting above-mentioned technical scheme, in the middle of the process that the sampling tube descends, under the effect of rivers, the ball sealer is located the top of drain pipe for water in the middle of the sample cell can discharge in the middle of the wash port, the sample is ended and in the middle of the process of upward movement, ball sealer downstream and sealed at the sampling tube top under hydraulic effect heart, make water can't enter into the sampling tube in the middle of from the sampling tube top, realize rising in the middle of the process sealed to the sampling tube.

The utility model discloses further set up to: the sampling tube overcoat is equipped with solid fixed ring, gu the fixed ring overcoat is equipped with and gu fixed ring threaded connection's go-between, go-between and a plurality of connecting plate fixed connection are in the same place.

Through adopting above-mentioned technical scheme, through setting up go-between and solid fixed ring, be convenient for fix the sampling tube on the connecting plate to can be in the same place the firm connection of sampling tube and drain pipe.

The utility model discloses further set up to: the sealing ball is a rubber ball.

Through adopting above-mentioned technical scheme, set up the ball sealer into the rubber ball for in the middle of the process that rises, the ball sealer can be inseparabler through the elasticity of self seals the top of sampling tube.

To sum up, the utility model discloses compare and have following beneficial effect in prior art:

the utility model discloses a set up drain pipe, wash port and ball sealer, in the middle of the sampling tube descends, the ball sealer is located the top of drain pipe, makes the water in the middle of the sample tube discharge in the middle of can passing through the wash port, and the sample is over and in the middle of the upward movement process, the ball sealer moves downwards and seals at the sampling tube top under the hydraulic effect center, makes water can't enter the sampling tube in the middle of from the sampling tube top, realizes the sealing to the sampling tube in the middle of the process of rising;

according to the invention, the sealing ball is set to be the rubber ball, so that the sealing ball can more tightly seal the top of the sampling tube through the elasticity of the sealing ball in the rising process.
