Description
Technical field
The utility model relates to a kind of environmental monitoring instrument, particularly a kind of water examination sampling thief.
Background technology
Current, under water quality detection personnel mostly need in the time carrying out water quality detection in water or hand-held bucket sample in stretching into water, and in the time that different depth water sample is sampled, sampling bottle need to be moved down into after certain depth at open bottle cover, existing situation is to use good main equipment to accomplish, but its use cost is higher, and because weight is very much not portable, but in existing simple device, there is no good sampling apparatus, if sampling depth is inadequate simultaneously, also can cause testing result under-represented.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple to operate and can determine the water examination sampling thief of sampling depth.
The technical solution of the utility model is achieved in that a kind of water examination sampling thief, comprise pump bowl, surge flask, sampling bottle and soup stick, described pump bowl is connected and fluid communication by the first conduit with described surge flask, and the mouth of pipe that described the first conduit is positioned at one end of described surge flask is positioned at the bottleneck of described surge flask; Described surge flask is connected and fluid communication by the second conduit with described sampling bottle, the mouth of pipe that described the second conduit is positioned at one end of described surge flask closes on the bottom of described surge flask, and the mouth of pipe that described the second conduit is positioned at one end of described sampling bottle is positioned at the bottleneck of described sampling bottle; Described sampling bottle is connected and fluid communication by the 3rd conduit with described soup stick, and the mouth of pipe that described the 3rd conduit is positioned at one end of described sampling bottle closes on the bottle end of described sampling bottle; Described soup stick shaft indicates scale, and the water intake end of described soup stick is equipped with the suction nozzle with filter screen, and described suction nozzle is fixedly connected with by screw thread with described soup stick; The volume of described surge flask is V1, and the volume of described sampling bottle is V2, V1=0.5V2～1.5V2, and described surge flask adopts heavy wall vial.Described surge flask volume is difficult for excessive, described surge flask volume is excessive can cause the variation of system internal pressure less, need repeatedly bleed and just can complete the sampling to water sample, but that described surge flask volume is also difficult for is too small, described surge flask volume is too small can not have buffer action under individual cases.
Above-mentioned water examination sampling thief, described soup stick is two or more, it is internal thread that there are external thread, the other end in wherein one end of each soup stick, is threaded connection and fluid communication between two described soup sticks.
When use, described pump bowl, described surge flask, described sampling bottle and described soup stick are connected to conducting with conduit successively, then described soup stick test is arrived to the required water layer of water quality sampling, follow with described pump bowl in sampling bottle described in water sample suction, until stop in the satisfied detection of water sample needs, and in the time getting the water sample of different depth, only need change described sampling bottle and described soup stick, without changing described surge flask and described pump bowl.When within the scope of arm exhibition, water body samples, only need to keep soup stick vertical with the water surface, arrive after predetermined depth at described suction nozzle, with pump bowl by this degree of depth water sample suction sampling bottle, in the time that the water sample water yield meets detection demand, can stop pumping, in the time that water sample no longer flows into sampling bottle, soup stick can be packed up, the water sample degree of depth can be read by the scale on soup stick, for the water body sampling that exceeds arm exhibition scope, the water sample degree of depth can be by simply calculating, and utilizes the angle of soup stick and level and soup stick to enter water length and calculate the water sample degree of depth.
The beneficial effects of the utility model are:
1. the utility model is simple in structure, reasonable in design, easy to operate, practicality is high, function admirable and easy to carry, can increase work efficiency.
2. can determine comparatively accurately, easily sampling depth, improve the representativeness of testing result, reduce water examination personnel's repetitive operation.
3. the surge flask in the utility model can be avoided effectively because misoperation causes the pollution of excessive water sample to whole device, effectively avoids the pollution between different water samples simultaneously, has improved the representativeness of testing result.
