Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises an outer shell 1 with an opening at the upper end, a balancing weight 2 is fixed at the bottom of the outer shell 1, an inner shell 3 is installed in the outer shell 1, the inner shell 3 is attached to the inner wall of the outer shell 1 and can move up and down, a tension spring 4 is connected between the bottom of the inner shell 3 and the bottom of the outer shell 1, a plurality of water inlet holes 5 are distributed on the circumference of the top of the side wall of the inner shell 3, the inner shell 3 is positioned in the outer shell 1 under the action of the tension spring 4, and the water inlet; a horizontal floating plate 6 is arranged in the inner shell 3, the floating plate 6 floats to the top of the inner shell 3 to seal the water inlet hole 5, and a plurality of vertical first through holes 7 are formed in the floating plate 6; the top of the inner shell 3 is connected with a lifting rope 8.

The bottom of the outer shell 1 is provided with a second through hole 9 for balancing the water pressure of the upper end and the lower end of the inner shell 3 during sampling.

The top of 3 inner walls of interior casing be big end down's toper, inlet opening 5 is seted up on the conical surface, kickboard 6 be can with 3 top complex cones in interior casing, conical surface cooperation can make kickboard 6 more effective seal inlet opening 5.

The top of the inner shell 3 is screwed with an end cover 10 through screw threads, and a water sample in the inner shell 3 can be taken out by opening the end cover 10.

The upper surface of the floating plate 6 and the lower surface of the end cover 10 are respectively provided with a magnet 11, and the two magnets 11 are mutually attracted and arranged, so that the pressing force between the floating plate 6 and the conical surface of the shell can be increased, and the water inlet 5 is more effectively sealed.

The position that the inner wall top of shell body 1 and inlet opening 5 are relative is equipped with round rubber pad 12, improves the sealed effect of 5 outer ends of inlet opening.

After the side wall of the floating plate 6 and the conical surface of the side wall of the inner shell 3 are compressed, a gap is reserved between the upper end of the floating plate 6 and the top of the inner shell 3, so that the conical surface can be effectively compressed, and the situation that the upper end of the floating plate 6 is pushed against the top of the inner shell 3 to cause the conical surface to be not compressed is avoided.

When the utility model is used, firstly the lifting rope 8 is discharged with the same length as the sampling water depth, then the device is put into the water body, the device sinks under the action of gravity, under the action of the tension spring 4, the water inlet 5 is positioned in the outer shell 1 and is opposite to the rubber pad 12, the outer end of the water inlet 5 is sealed, when the device sinks to the sampling depth, the lifting rope 8 is tensioned and exerts upward tension on the inner shell 3, and the outer shell 1 is exerted downward tension by the counterweight block 2, therefore, the tension spring 4 is lengthened, the upper end of the inner shell 3 and the water inlet 5 extend out of the outer shell 1, the water inlet 5 is opened, at the moment, the water enters the inner shell 3 from the water inlet 5 and flows to the lower part of the floating plate 6 through the first through hole 7, the floating plate 6 is kept still for a period of time at the depth, the conical surface of the floating plate 6 gradually moves upwards, the attraction between the two magnets 11 is gradually increased, when, the inner end of the water inlet hole 5 is sealed by the floating plate 6, under the action of buoyancy and the attraction force of the magnet 11, enough pressing force is kept between the conical surface of the floating plate 6 and the conical surface of the inner shell 3, the inner end of the water inlet hole 5 can be effectively sealed, then the device is lifted out of the water, and the water sample in the inner shell 3 can be taken by opening the end cover 10.

The utility model discloses under the condition for practical electronic component, can guarantee effectively sealed of interior casing 3, no matter dust process still promotes the process down, all can avoid not holding the deep water sample of layer to mix in the sample, the effectual accuracy that improves the inspection of can sampling.
