Referring to fig. 1, a sampling device for sampling liquid according to an embodiment of the present invention includes a U-shaped tube 10, balls 20 disposed in the U-shaped tube 10, and a gas source 30.
The bottom 11 of the U-shaped pipe 10 of this embodiment is connected to and communicates with a bevel pipe 40, and the bevel pipe 40 is disposed obliquely upward with respect to the bottom 11.
The pipe diameter of the bevel pipe 40 in this embodiment gradually decreases from a direction away from the pipe bottom 11, and the balls 20 can enter the bevel pipe 40 from the pipe bottom 11 along the lower pipe wall 41 of the bevel pipe 40 to seal the bevel pipe 40. In the present embodiment, the portion of the upper tube wall 42 of the bevel-mouth tube 40 connected to the U-tube 10 is formed with a reduced-diameter portion 101, and the diameter of the reduced-diameter portion 101 is smaller than the outer diameter of the ball 20. So that the balls 20 can only enter the bevel-in tube 40 when moving in the U-shaped tube 10 and realize the sealing of the bevel-in tube 40.
The air source 30 of the present embodiment is capable of blowing air toward the one end pipe orifice 12 of the U-shaped pipe 10 to allow the balls 20 to enter into the bevel pipe 40 from the pipe bottom 11 and to block the bevel pipe 40, and at the same time, to discharge the liquid placed in the U-shaped pipe 10 to the outside. That is, the sampling device of the present embodiment can discharge the liquid entering the U-shaped tube 10 by blowing the air source 30 into the tube orifice 12 of the U-shaped tube 10.
As can be seen from the above, when the sampling device of the present embodiment works, the balls 20 stay at the bottom 11 of the U-shaped tube 10 due to the gravity, and when the U-shaped tube 10 is inserted into the liquid, the liquid can enter the U-shaped tube 10 from the bevel pipe 40 until the bevel pipe 40 moves to the required sampling depth of the sampling device; then, the air source 30 is directed to the pipe orifice 12 of the U-shaped pipe 10, on one hand, the liquid in the U-shaped pipe 10 is completely discharged into the liquid in the U-shaped pipe 10, on the other hand, the ball 20 can be blown into the bevel-mouth pipe 40 to realize the plugging of the bevel-mouth pipe 40, and in the process, the empty U-shaped pipe 10 and the bevel-mouth pipe 40 can be made to enter the depth to be sampled in the liquid. Then, the air source 30 stops blowing air into the U-shaped pipe 10, so that the ball 20 releases the blocking of the bevel-mouth pipe 40 under the action of gravity and the pressure of the liquid entering the bevel-mouth pipe 40, the liquid at the position of the bevel-mouth pipe 40 enters the U-shaped pipe 10 through the bevel-mouth pipe 40, and then the air source 30 blows air into the pipe orifice 12 of the U-shaped pipe 10, and blows out the part of the liquid from the U-shaped pipe 10, namely, the sampling of the liquid is realized.
Wherein, be provided with baffle 401 on the inner wall of bevel connection pipe 40 of this embodiment, ball 20 can support and lean on baffle 401 to shutoff bevel connection pipe 40, so that the shutoff of ball 20 to bevel connection pipe 40 when moving in bevel connection pipe 40 to improve the leakproofness when ball 20 shutoff bevel connection pipe 40.
Specifically, the shutter 401 of the present embodiment is provided in a tapered structure, and the aperture of the shutter 401 gradually decreases from a direction away from the balls 20. In order to enhance the blocking of the shutter 401 when the balls 20 are abutted against the shutter 401, a rubber plate may be specifically attached to the shutter 401 against the end face of the balls 20.
In this embodiment, the lower pipe wall 41 of the bevel pipe 40 of this embodiment is in transitional connection with the bottom 11 of the U-shaped pipe 10, so that the balls 20 enter the bevel pipe 40 from the bottom 11 of the U-shaped pipe 10 along the lower pipe wall 41 of the bevel pipe 40, and the sealing of the bevel pipe 40 is achieved.
