Abstract
A layered water sample synchronous sampler is characterized in that it is provided with a support, the support is arranged with vertical layers, the layer is provided with a plurality of parallel division located water sampling pipe, one end of which is taken as water intake, water outlet on the other end is communicated with the corresponding sampling bottle which is located with exhaust port and movable enclosed water sample outlet, the exhaust is communicated with the corresponding air inlet of the negative pressure divider, the air outlet located in which is communicated with vacuum pump by conduit. Buffer bottle is suggested to be arranged between the air outlet of the negative pressure divider and the vacuum pump, the air outlet of the negative pressure divider is communicated with the buffer bottle by conduit, the air outlet of the buffer bottle is communicated with the vacuum pump by conduit, and the buffer bottle is provided with movable enclosed water outlet. Vertical layer of the support is provided with scale and divisions are arranged in equidistance.
Description
Technical field
The utility model relates to the equipment that is used for gathering in ground, Research of Environmental Sciences water sample, and particularly a kind of layering water sample synchronized sampler is applicable to the layering water sampling in shallow lake and river.
Background technology
Water sampling is one of indispensable instrument of lake environment and ecosystem research.About the general high 50cm of hydrophore that produces both at home and abroad, gather water sample and be generally 50 centimeters thickness compound samples at present.When carrying out the distribution characteristics research of lake physics, biology, chemical parameters Characteristics of Vertical Distribution, especially near interface, these samplings are difficult to reach the research requirement.Lake research needs different water layers or different water sample point synchronous acquisition water sample usually in addition, needs great amount of manpower and material resources with existing single water sampler, and needs the staff to coordinate accurately almost can not realize.Prior art all can not solve above-mentioned difficult point.The utility model can overcome the defective of prior art, aspect research water body material vertical demixing and boundary material exchange, plays a great role.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of layering water sample synchronized sampler that is applicable to shallow lake and river layering water sampling is provided.Above-mentioned purpose of the present utility model is realized by following technical scheme: layering water sample synchronized sampler, it is characterized in that being provided with a support, support is provided with vertical demixing, layering is provided with many parallel, layer water gathering tube every layout, water gathering tube one end is a water inlet, other end water delivering orifice is communicated to corresponding sampling bottle by conduit, sampling bottle is provided with the water sample outlet of exhausr port and movable sealing, exhausr port is communicated to the corresponding air intake opening of negative pressure divider by conduit, the negative pressure divider is provided with a gas outlet, is communicated to vacuum pump by conduit.Preferably be provided with surge flask between negative pressure divider gas outlet and the vacuum pump, negative pressure divider gas outlet is communicated to surge flask by conduit, and the gas outlet of surge flask is communicated to vacuum pump by conduit, and surge flask is provided with the freeing port of movable sealing.Vertical demixing on the support can be provided with scale, and layer is every can be equidistant.
Advantage of the present utility model and effect: (1) can obtain lake water column different levels and a plurality of water samples of measuring point synchronously, fast; (2) can improve the layering precision (1cm layering) of gathering water sample; (3) easy and simple to handle, only need a people to get final product.
Description of drawings
Fig. 1 is the utility model overall construction drawing.
Embodiment
Referring to Fig. 1, can make accurately equidistant layering and be provided with the support 1 of scale by aluminium alloy, water gathering tube 2 (water gathering tube quantity as required can less than hierarchy number) is set in each layering, water gathering tube one end is a water inlet 13, other end water delivering orifice 14 is communicated to corresponding sampling bottle 3 by conduit, sampling bottle is provided with the water sample outlet 5 of exhausr port 4 and movable sealing, exhausr port 4 is communicated to the corresponding air intake opening 7 of negative pressure divider 6 by conduit, the negative pressure divider is provided with a gas outlet 8, be communicated to surge flask 9 by conduit, its gas outlet 10 is communicated to vacuum pump 11 by conduit, and surge flask is provided with the freeing port 12 of movable sealing.During device work, start vacuum pump, at first making surge flask is negative pressure (surge flask is set can make the negative pressure effect increase), make negative pressure distribute inner chamber to become negative pressure by conduit, by the effect of conduit, sampling bottle becomes negative pressure, and then each water layer water body is under the effect of lake surface air pressure, be pumped to sampling bottle, and then finish the sampling overall process.Because pressure propagation speed is exceedingly fast, so each sampling bottle almost arrives negative pressure state simultaneously, so the water body of lake different depth almost is sucked into sampling bottle simultaneously along each water layer sampling pipe, reaches the purpose of synchronization gain lake water column different levels and measuring point.During use, support is vertically put into and hammered into shape into the bottom, the upper end support fixation, all the other equipment can be placed on the work boat.
