Embodiment Construction
[0026] The present invention will be described in detail below through specific examples.
[0027] This embodiment proposes a portable layered water intake device, which includes a housing, a fixed base and a water sample extraction device, wherein the housing can be disassembled and assembled according to the actual water intake depth at intervals of 20 cm. The surface of the shell 7 is provided with several water intakes 9, and each water intake is an ellipsoid-shaped accommodation space at the connection with the shell, and a small rubber ball 11 is restricted in the accommodation space. When the water intake is along the direction of water flow, the small rubber ball is blocked. The connection port between the water intake and the shell; the upper end of the shell is provided with a device holder 8, and 3 device holders are evenly arranged on the same horizontal plane, painted in brighter colors, and play the role of marking the horizontal plane.
[0028] Base comprises an...

The invention discloses a portable layered water taking device which comprises a shell, a fixing base and a water sample taking device, wherein a plurality of water taking holes are formed in the surface of the shell; the connecting part of each water taking hole and the shell is an elliptic spherical accommodation space; a small rubber ball is constrained inside the accommodation space; the fixing base comprises an anti-buoyancy weight, a lower cover and a sliding rod fixing device; a sliding rod is fixed inside the sliding rod fixing device; the sliding rod is sleeved by a large rubber ball; a rope is connected with the upper part of the large rubber ball; and the water sample taking device comprises a hard water taking tube, a soft water taking tube and a peristaltic pump. Water samples at different depths are taken by using the peristaltic pump layer by layer, and the sampling depth is precisely controlled by using the pull rope with scales. The portable layered water taking device is simple in structure and low in cost, can be assembled in a modularized manner, can be assembled by multiple layers according to depths of water bodies expected by actual testing demands, can be conveniently carried over after being disassembled, can be used for precisely taking water bodies at different depths, can be fixed at a sampling site, and is convenient and rapid in sampling operation.
Description
technical field [0001] The invention relates to the technical field of sample collection devices, in particular to a portable layered water intake device and a method for using the device. Background technique [0002] In fields such as environmental protection, it is often necessary to conduct stratified sampling of water bodies and conduct hydrochemical analysis of water samples at different depths. The traditional layered sampling method is to draw samples by hanging buckets with ropes, and take water at different depths in multiple times. This method is difficult to guarantee the sampling accuracy. Afterwards, the method is improved, adopting the device of setting interlayer water tanks, and water intakes that can be opened and closed simultaneously are set on each layer of water tanks, and water of different depths can be taken simultaneously. Although this method improves the sampling accuracy, the sampling takes a lot of effort of the operator, and the safety of the ...
