Furthermore, a thread-shaped winch groove is formed in the winch, and the water pipe is wound in the winch groove.

Furthermore, a lead screw in transmission connection with the winch is arranged on one side of the winch, a lead screw nut is arranged on the lead screw, a distribution block is fixedly connected below the lead screw nut, a through hole is formed in the distribution block, and the lower end of the water pipe penetrates through the through hole and then is immersed in water.

Furthermore, a feed bar is arranged below the lead screw, and the distribution block is arranged on the feed bar in a sliding manner.

Furthermore, a plurality of limiting plates are arranged on the circumference of the winch through the support, and the water pipe is prevented from being separated from the groove of the winch.

Furthermore, the sampling bottle has a plurality of, and communicates with the water pipe through the reposition of redundant personnel pipeline, all is equipped with pinch valve on every reposition of redundant personnel pipeline.

Furthermore, a rinsing pipeline is connected to the water pipe, and a pinch valve is arranged on the rinsing pipeline.

Furthermore, the box body is arranged on a cross beam, and the cross beam is fixed with the unmanned ship.

The utility model has the positive effects that: according to the utility model, the winch is used for lowering the sampling head, the winch can be lowered to a specified depth according to requirements for sampling, the sampling pump is used for directly pumping water into the sampling bottle, and the pipeline is automatically recovered after sampling is finished. This operation process automation realizes, need not personnel and operates the sample on the spot, has improved the convenience of sample greatly.

Detailed Description

As shown in the attached figures 1-5, the sampling device comprises a box body 1, a winch 7 fixed in the box body 1, a water pipe wound on the winch 7 and a sampling bottle 6 communicated with one end of the water pipe, wherein the other end of the water pipe is connected with a sampling head 3 with a balance weight, the box body 1 is divided into an upper layer and a lower layer by a partition plate, the winch 7 is arranged in a lower layer of space, a bottle lining 4 is arranged in an upper layer of space, and the sampling bottle 6 is arranged in the bottle lining 4.

In this embodiment, there are 4 sampling bottles 6, which are all communicated with the water pipe through the shunt pipes, and each shunt pipe is provided with a pinch valve 11, and the water pipe is also communicated with a rinsing pipe 15 with the pinch valve 11. A sampling pump 12 is arranged on the water pipe 1, and the sampling pump 12 is a peristaltic pump in the embodiment. A pump valve cover 5 is arranged on one side of the bottle liner 4, and a sampling pump 12 and a pinch valve 11 are both arranged in the pump valve cover 5.

The winch 7 is provided with a thread-shaped winch groove, the water pipe is arranged in the winch groove, the winch 7 is driven to rotate by a motor, and the sampling head 3 is placed or recovered in the rotating process. And be equipped with limiting plate 14 through the support in capstan winch 7's four-axis, in this embodiment, limiting plate 14 is 4, and evenly distributed is around capstan winch 7, prevents that the water pipe from deviating from in the capstan winch groove.

Preferably, a lead screw 8 in transmission connection with the winch 7 is arranged on one side of the winch 7 where the sampling head 3 is placed, a lead screw nut 9 is arranged on the lead screw 8, a distribution block 13 is fixedly connected below the lead screw nut 9, the distribution block 13 is slidably arranged on a feed rod 10, and the feed rod 10 is fixedly arranged below the lead screw 8. The distribution block 13 is provided with a through hole through which the lower end of the water pipe passes and enters the water.

Preferably, the box body 1 of the utility model is arranged on a cross beam, and the whole body can be fixed on the unmanned ship through the cross beam. And a control device is also arranged.

When the sampling device is used, the sampling head 3 is only required to be lowered to a specified depth, the box body 1, the sampling bottle 6 and other equipment are still on the ship, the counter weight required by the sampling head 3 is small, and the use is more convenient.

When the unmanned ship is used, the unmanned ship is driven to a specified water area, and the longitude and latitude of the position are recorded. When needing the sampling, the manual work is passed through the remote controller at the bank and is sent the instruction, sets up the sampling depth, sets up the sampling volume, and after the instruction was received to the sample thief, transfer sampling head 3 through inside capstan winch, transfer appointed length water pipe to appointed layer depth voluntarily, after the sample pump is with the water sample that awaits measuring rinses the pipeline, leave the appearance with appointed water yield to sampling bottle 6. And after sampling is finished, automatically recovering the pipeline. The operation process is automatically realized, only personnel are needed to carry out remote control operation, and the personnel are not needed to carry out on-site operation sampling. And automatically recording the sampling amount, the sampling layer depth and the longitude and latitude information. The sampling head adopts plastic construction, avoids the iron material to pollute and waits to get the water sample.
