Problems solved by technology

Their outstanding disadvantages are: they cannot obtain continuous water samples, and cannot meet the actual needs of continuous sampling or high-density sampling; under similar workload conditions, static sampling takes a lot of time and costs a lot

Embodiment Construction

[0007] The utility model has a drag body 3, which can maintain the stability of the entire water collector. A submersible pump 1 is installed in the middle and lower part of the trailer 3, the tail of the latter is connected with a cable 14, and the joint of the cable 14 must be sealed with water-resistant glue to ensure safety and reliability. A sensor 2 is installed in the middle and upper part of the trailer 3, one end of the latter is connected with a cable 13, the water inlet of the water pipe 4 is connected with the water outlet of the submersible pump 1, and the water inlet and the water outlet are fixed together with a pipe clamp 5. The water pipe 4 extends upwards from the tow body 3, and the upper end of the hook 7 is fixed together with waterproof glue between the hook loop 9 and the nylon tie 10 through the steel cable 8 and placed on the upper part of the water pipe 4. The lifting ring 6 is hung on the hook body of the lifting hook 7, and the lower end of the lifting ...

Abstract

It is a drag sailing water sampler with a dragged body, which has a dive pump on its middle and down part and a sensor on its middle and upper parts inside. The water-in mouth of the pipe is connected with the water-out mouth of the dive pump and the water-in mouth and water-out mouth are fixed together by use of catcher and the pipe sticks out of the drag body and the hanging hook upper end is fixed together with hook ring and nylon through steel cable and is located on the upper end of the water pipe. The wire and cable are located on one side of the water pipe through anti-water adhesive tape. The advantages in this invention are the following: first it can make water sample continuously with high intensity in sailing status; second to accurately control water sample depth and adjust sample depth when needed on real time; third to improve the sample efficiency and lower the investigate cost.

Description

Technical field [0001] The invention relates to a water harvester, in particular to a towed water harvester. Background technique [0002] In conducting rivers, lakes, ocean physics, chemistry, biology, and environmental surveys, water samples must be collected. For many years, the metal upside down water harvester imported from the former Soviet Union in the 1950s and the organic glass water harvester imported from Japan by Professor Tang Siqi of Ocean University of China in the last century and later imitated by the Qingdao Institute of Oceanography have been used. The above two kinds of water collectors are connected, fixed and lowered by steel wire ropes, and the hammer is triggered to realize the collection of water samples at the predetermined level when the ship is stopped. Due to the flow of the water body, the wire rope is bent in the water body, resulting in the inconsistency between the preset horizon and the actual water depth. Although the approximate value of the wi...
