Detailed Description

The present invention will be further described with reference to fig. 1 to 4.

A river water sampling device comprises a suction component 1, a floating body 2, a transfer bottle 3, a sampling pipe 4 and a floating and sinking component 5. The suction assembly 1 comprises a piston cylinder 13, a connecting bottle 14 and a sampling bottle 15; the float and sink assembly 5 comprises a sheave 6 and a weight 7. The floating body 2 may be self-driven or non-driven as desired. The piston cylinder 13 and the hose are respectively arranged at two ends of the connecting bottle 14, the piston cylinder 13 is detachably connected with the connecting bottle 14, the connecting bottle 14 is communicated with the transfer bottle 3 through the hose 17, and the sampling bottle 15 is arranged between the piston cylinder 13 and the hose. The transfer bottle 3 is fixedly connected to the floating body 2, a reel 6 is connected to the floating body 2, and one end of the reel 6 is connected with a weight 7 through a lifting rope. One end of the sampling tube 4 is communicated with the transfer bottle 3, and the other end is fixed with the weight 7. One end of the sampling pipe 4 is connected to the bottom of the transfer bottle, and one end of the hose is connected to the top of the transfer bottle. The reel 6 is driven by the motor 8 to rotate, and the weight block drives one end of the sampling tube 4 to float up and down under the drive of the motor so as to collect water quality samples at different depths.

Specifically, the weight 7 includes a first connecting block 9 and a second connecting block 10; first connecting block 9 and second connecting block 10 pass through the bolt and form and can dismantle the connection, be provided with fixed orifices 11 on the pouring weight 7, the end of sampling pipe 4 is provided with flange 12, the end cover of sampling pipe 4 is established and is connected in fixed orifices 11, flange 12 offsets with the terminal surface of pouring weight 7 to avoid pouring weight 7 and sampling pipe 4 to take place to break away from.

One end of the connecting pipe 14 extends outwards to form a connecting nozzle 16, one end of the hose is fixedly connected with a connecting cap, and the connecting cap is connected with the connecting nozzle through threads. Under the effect of piston cylinder 13, connecting bottle 14, sampling bottle 15 and transit bottle form the negative pressure, and the quality of water sample gets into transit bottle through the sampling pipe in proper order, and transit bottle gets into the connecting bottle through the hose, and the connecting bottle communicates with each other with the sampling bottle, therefore the sample finally can get into in the sampling bottle. Be connected with the stop valve on the hose, when many bottles of samples under the same degree of depth of needs gathering, close the stop valve, it can to change the sampling bottle.

When the depth of a sample to be collected is large and the piston rod cannot provide enough negative pressure, the piston rod can be replaced by a negative pressure machine.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
